专利说明:

The invention relates to machine tool industry.
The aim of the invention is to increase the processing productivity of COMPLEX contours of deep annular 5 grooves by automating the installation and positioning of tool blocks.
. In FIG. 1 shows a lathe support, front view; in Fig.2 - u section Aa in Fig. 1; in FIG. 3 is a section BB in FIG. 1; in FIG. 4 - the position of the tool holder in the cavity of the machined groove.
The lathe support for processing 15 deep annular grooves comprises a housing 1 mounted on the transverse slide of the support of the machine (not shown); the upper part of the housing 1 is made less than 20 g in width B in the grooves of the workpiece 2. The upper part of the housing 1 is made in the form of a half coupling with end teeth 3 and 4 located at an angle of 90 ° to each other and interacting with teeth 5 and 6 interchangeable tool holders 7 and 8, equipped with one 9 or two cutters 10, respectively, for one- and two-sided processing. The tool holders 7 and 8 are drunk on the case with the help of a clamping element made in the form of a vertically mounted rod 11, which in the upper part is equipped with a T-head 12 / 'included in the corresponding ₃₅ grooves of the replaceable tool holders 7 and 8. Choosing a gap the height of the grooves of the toolholders 7 and 8 and the T-shaped head 12 is carried out using gaskets 13. Dimension G ₄ θ across the width of the toolholders 7 and 8 is slightly smaller than the dimension B in the grooves of the workpiece. The rotation of the rod 11 and the toolholders 7 and 8 is carried out by the drive 14 through the rack 15 and the gear 16 mounted on the rod 11. The rod 11 and the toolholders 7 and 8 are raised to a size exceeding the height of the teeth 3, 4, 5 and 6 by the drive 17, connected to the wedge mechanism 18, the tightness of which is provided by a package 19 of Belleville springs.
The eubes 3-6 are cleaned with compressed air entering through the openings 20, the bore 21, the openings 22 - 26 of the rod 11. The lubricating coolant is supplied to the cutting zone to the cutters through the openings 27, 29 and pipelines 30, 31 and 32. The caliper housing is located pipelines 33 and 34 for supplying a cutting fluid.
The proposed support works as follows.
Pre-cut a rectangular groove width B to the required depth. Cutting of the sides of the expanded cavity of the groove is carried out by cutters 9 in the left and right versions installed in the tool holder 7. Simultaneous processing of the sides of the expanded cavity of the groove is performed by two cutters 10 of the replaceable tool holder 8. Installation of tool holders 7 and 8 with cutters is performed outside the workpiece 2. By means of the longitudinal and lateral displacement of the slide, the caliper with fixed toolholders is inserted inside the groove. Next, with the help of the actuators 17 and 14, the release and rotation and re-fixing of the toolholders 7 and 8 in the working position and the processing of the surfaces of the expanded groove cavity occur. After processing, using the aforementioned drives, the tool holder 7 or 8 is rotated to its original position and the caliper is withdrawn from the groove.
The proposed device provides an increase in processing productivity by automating the process of fixing and securing in the right position interchangeable toolholders when processing hard-to-reach surfaces.

t3tf 1 -w-mf. h. J The invention relates to a machine tool industry. The aim of the invention is to improve the processing performance of complex contours of deep ring grooves by automating the installation and positioning of tool blocks. . FIG. 1 shows the caliper of the lathe, front view; in FIG. 2, section A-A in FIG. 1, in FIG. 3 section bb in fig. one; in fig. 4 - the position of the toolholder in the cavity of the grooves being worked. The caliper of the lathe for machining deep annular ditches comprises a housing 1 mounted on a cross slide of a machine caliper (not shown); the upper part of the housing 1 is made in width less than the dimension B of the groove of the workpiece 2. The upper part of the housing 1 is made in the form of a coupling half with end teeth 3 and 4 located at an angle of 90 ° to each other and interacting with the teeth 5 and 6 of the tool holder 7 and 8, equipped respectively with one 9 or two crests 10 for one- and two-sided processing. The tool holders 7 and 8 are mounted on the housing with the help of a clamping element, made in the form of a vertically mounted rod 11, which in the upper part is equipped with a T-shaped head 12, which fits into the corresponding grooves of the replaceable tool holders 7 and 8. The choice of clearance the height of the grooves of the tool holders 7 and 8 and the T-shaped head 12 is carried out using gaskets 13, Dimension G in width of the tool holders 7 and 8 are somewhat smaller than the dimension B of the groove of the workpiece. The rotation of the rod 11 and the tool holders 7 and 8 is carried out by the drive 14 through the rail 15 and gear 16 mounted on the rod 11. The rod 11 and the tool holders 7 and 8 are raised to a size that exceeds the height of the teeth 3, 4, 5 and 6 using the actuator 17 connected to the wedge mechanism I, the tension of which is provided by a package of 19 cup springs. Cleaning the teeth 3-6 is performed with compressed air coming through the holes 20, the bore 21, the holes 22 - 26 of the rod 11, the cutting fluid is supplied to the EI the cutters through the holes 27 952 28 and 29 and the pipe rovody 30, 31 and 32. The caliper body has ducts 33 and 34 for supplying coolant. The proposed support works as follows. Pre-cut a rectangular groove of width B to the required depth. The sides of the enlarged groove cavity are cut by the cutters 9 in the left and right versions installed in the tool holder 7. Simultaneous processing of the side surfaces of the expanded groove cavity is made by two cutters 10 of the replaceable tool holder 8. The tool holders 7 and 8 are installed with the cutters outside the workpiece 2. Through the longitudinal and transverse movements of the slide, a caliper with fixed tool holders is inserted inside the groove. Next, using the drives 17 and 14, the release and rotation and re-fixation of the tool holders 7 and 8 in the working position and surface treatment of the expanded cavity of the groove occur. After finishing the machining, using the aforementioned drives, the toolholder 7 or 8 is rotated to the starting position and the caliper is withdrawn from the groove. The proposed device provides an increase in processing performance by automating the process of fixing and securing the replaceable tool holders in the desired position when machining hard-to-reach surfaces. Claims 1.
