    The invention relates to technical measurements of taper locking threads, namely, devices for measuring the relative position of a taper thread diamat and its base end on a machine tool. A device is known for measuring the relative position of the diameter of the tapered thread and its base end face on a machine, comprising a housing with mechanisms for adjusting movements, for example, on the machine slide guides mounted on the housing with possible movement in the direction of the center line of the machine measuring gauge bearing contact element designed to interact with the control with the thread profile, and linear displacement meter, designed to interact with the control with the base end of the thread l, ment of the device when finalizing details rezry by treatment impossible, and in addition, its use reduces a manufacturer of papers, the processing equip Vani. The aim of the invention is to improve the performance of the device and expand its technological capabilities. This goal is achieved by the fact that the device for measuring the relative position of the diameter of the conical thread and its base end on the machine contains a housing with mechanisms for setting movements, placed ,. For example, on the machine slide guides mounted on the housing with the ability to move in the direction of the machine center line the measuring carriage, bearing contact element designed to interact with the control with the thread profile and linear displacement meter, designed to interact with the control with the base end of the thread1 equipped with a second measuring carriage installed between the body and the first measuring carriage oh with the possibility of movement in a direction perpendicular to the line of centers tank, and a second carrier measuring linear movement cooperating with the body. In this case, the second measuring carriage on the body and the first meter on the carriage to the second one are installed with the help of flat springs. The first and second measuring carriages are installed with a preload by means of a spring. A shaft-bore connection is provided between the second measuring carriage and the housing. The contact element is provided with at least one tooth with a profile, f n corresponding to the profile of the controlled thread. In addition, the contact element is provided with at least two teeth and is rotatably located on the axis. Moreover, the contact element is installed with the possibility of support on the carriage through two springs. FIG. 1 shows a device for testing parts with internal thread, general view; in fig. 2 - the same, top view; in fig. 3 - device for testing parts with external thread, general view; in fig. 4 - the same, top view. In the device of FIG. 1 and 2 on the slide 1 of the machine caliper there is a carriage 2 with a guide 3 on which the device body 4 is located. A second measuring carriage 7 is mounted on the body 4, which is moved together with the carriage 2 along the carriage 1, on the flat springs 5 and b. A spring 8 is installed between the body 4 and the second measuring carriage 7, which provides a preliminary tension of the flat springs 5 and 6. On The housing 4 is fixed with a stopper 9 with a trunnion 10, which mates with a hole 11 made in the second measuring carriage 7 and thereby limits the ability of the second measuring carriage 7 to move relative to the housing 4. There is a stop 1 on the stopper 9 2, with which the tip 13 of the second linear displacement meter 14 interacts, secured by a bracket 15 on the underside of the second measuring carriage 7. In an embodiment of the device shown in FIG. 1 and 2, the second measuring carriage 7 is L-shaped. On the second measuring carriage 7 by means of flat springs 16 and 17 placed at right angles to the flat springs 5 and b, the first measuring carriage 18 is installed. On the first measuring carriage 18 in its recess 19 the contact element 20 is rotatably mounted on the axis 21 , to which it is pressed by the springs 22. The contact element 20 is provided with two teeth 23 spaced apart from its axis of rotation, the profile and the distance between which corresponds to the profile of the measured diameter. On the first measuring carriage 18, the first gauge 25 is displaced with the help of the clamp 24, which, when controlled by its tip 26, contacts the base end of the cut. The device shown in figure 1, 2, works as follows. During machining of part 27, when thread 28 is cut in it and base end 29 is cut, the device is retracted from the treatment zone by carriage 2. At the end of the machining process, the carriage 2, carrying the device, moves to a fixed stop and then using the slide 1 to the programmed position relation to the thread. The flat springs 16 and 17 at the same time ensure the coupling of the teeth 23 of the contact element 20 with the thread profile 2 &. Depending on whether the thread in this place has a diameter greater or less than the specified one, there is a greater or lesser displacement of the second measuring carriage 7 relative to the housing 4, which is recorded by the second gauge 14 linear displacements. The first linear displacement meter 2 registers the displacement of the first measuring carriage 18 from a predetermined position, taking into account the position of the base end of the thread. A number of different cases may occur. If the average internal diameter of the tapered internal thread is too large, and the base is too short, this does not adversely affect the characteristics of the threaded connection, and no thread rework is required. The same applies to the opposite case. Only in the case when the ratio of the size of the diameter of the thread and the baseline value is such that the characteristics of the threaded connection are not provided, there is a need to refine either the internal thread or its base end. The device for testing parts with external threads shown in FIG. 3 and 4, contains the same elements as the device shown in FIG. 1 and 2. In contrast to the device specified in this design, the probe of the first gauge 25 linear displacement interacts with a two-arm lever 30 mounted with a flat spring 31 on the first measuring carriage 18. On the other arm of the two-arm lever there is a contact tip 26, which interacts during control with the base end of the part. A threaded pin 32 with locknuts 33 and a spring 3.4 is placed between the lever arm 30, which interacts with the first gauge 25 linear displacements and the measuring carriage 18. Using this mechanism, it is possible to set the required pre-tension of the two-arm lever 30. The operation of this device is similar to the operation of the previous one. With the help of the slide 1 and the carriage 2, the device is moved to a predetermined position. The flat springs 16 and 17 provide the mating of the teeth 23 of the contact element 20 with the thread profile. The second measuring carriage 7 is displaced relative to the housing 4 depending on the diameter of the thread. This displacement is determined by the second gauge 14 linear displacements. The first meter 25 linear movements through the lever JU with the contact tip 26, interacting with the base end, registers the position of the latter. The table presents examples of possible measurement cases, where T1 is the deviation of the actual external thread radius at a given location from the target, T2 is the deviation of the actual position of the base end from the target, x is a constant factor. In case 1, rework is not required, since both the thread and the base end do not deviate from the target position. In cases 3 and 5, no further work is required either, since both T1 and T2 are undersized (case 3) or oversized (case 5), and therefore the mutual position of the external thread 35 and the base end 36 is correct. in this case (since the characteristic of the threaded joint is provided. In cases 2, 7 and 9, the external thread needs to be refined, because in case 2, the external thread is overestimated and the base height is underestimated. In case 7, the base thread has understated size, and in case ae 9 male thread is made with an oversized size. In general, in both embodiments of the device, the comparison of the recorded values of linear displacement meters allows you to determine if there is a need to refine the thread or the base end. Such a comparison can be made using, for example, an electronic device. i.e., the correction may be indicated in digital or analog form. Corrections may be entered into the machine manually or automatically. Thus, the application of the proposed device on the machine allows to significantly increase the productivity and technological capabilities of the control.
