    专利说明:

    The invention relates to mechanical engineering, in particular, to machines, designed for finishing machining of the tooth profiles of spur gears, for example, by shaving, honing, fine plastic deformation, etc. A known machine for finishing the profiles of cylindrical gears under free wheel conditions with a gear tool, comprising a stand with a stand, a support with a carriage wired from two parts is mounted on a guide that can be vertically moved installed in a round guide caliper, and the lower part, made in the form of a hinged top of the carriage, on the axis of the carriage, traverse with a rocker mechanism and drive, and a slider with a ruler, under It is installed in the guides of the cross member, the copier ruler is hinged to interact with the rocker mechanism when the slide is moved by the drive, the tool head is mounted for rotation in the round guides of the bottom part of the carriage, and the gear wheel is fixed in the centers of the front and tailstocks located on the frame with the possibility of adjusting the distance between them 1. This machine design makes it possible to obtain the teeth of the gears being machined with a certain width (with a decreasing thickness of the tooth across the width of the gear rim) only with parallel or diagonal tool feed. In other directions of the tool feed (for example, tangential), tapering on the treated teeth x is difficult. The purpose of the invention is the expansion of the technological capabilities of the machine. The goal is achieved by the fact that in the machine tool there is a frame with a stand on which a guide with a carriage made of two parts is installed with the possibility of vertical movement: a vertical part mounted in a round guide support , and the lower part, made in the form of the upper part of the carriage pivotally mounted on the axis, the traverse with the rocker mechanism and the drive, and the slide with the carbon line with the ruler movably installed in the grass guides races, with a copier ruler hinged to interact with the rocker mechanism when moving the slide by means of a drive, while the tool head is rotatably mounted in the round guides of the bottom of the carriage, and the gear to be machined is fixed in the centers of the front and rear heads located on the bed with the possibility of / adjusting the distance between them, the upper part of the carriage is equipped with bushings with self-aligning bearings, in which the axis is placed, intended for mounting on a crosshead, wherein one of the sleeves is formed eccentrically rotatable relative to the upper part of the carriage, FIG. 1 shows an example of a machine; in fig. 2 - position of the carriage in the position when the tool is fed in parallel; in fig. 3 - the same, in the position of an attractive tool feed; FIG. 4, the upper part of the carriage; FIG. 5 is a view A of FIG. 4. On the bed 1 is rigidly installed. a stand 2, on which vertical guides 3 a movable caliper 4 with a drive is movably mounted, a carriage 5 is mounted on the lower side of the caliper, an instrumental head 7 is placed in the lower part of the carriage so as to rotate in a circular guide 6 around the vertical axis H 8. On the base 1 of the machine, the front 10 and rear 11 heads 9 are installed in the longitudinal guides, in the centers of which the gear wheel 12 is mounted. The tooth profiles are processed by rotating the tool 8, the axis of rotation F which intersects the axis of rotation of the wheel 12 to be machined. In this case, the tool 8 has the ability to move along the axis M. The possibility of appropriate installation and movement of the tool 8 is provided by making the carriage 5 of three parts mounted movably relative to one another: the upper part 13, the traverse 14
    3 1
    and a slider 15. The upper part 13 is mounted in a circular guide 16 of the caliper 4 and can be rotated around a vertical axis coinciding with the axis H and fixed in the desired position. Thus, any feed direction can be set including S or S.
    On the top of the carriage 13 on the axis 17, the crosshead 14 is pivotally mounted for rotation around the horizontal axis L. On the underside of the crosshead, a slider 15 is installed in the longitudinal guide 18 with a preload, while the longitudinal guide 18 perpendicular to the axis L. the movements of the slide 15 (for turning the upper part of the carriage 13), as well as the tool head 7, are known and are not described in this technical solution.
    The slider 15 has, at one end, a length-adjustable bracket 19, on the axis of which a copier line 20 is installed, with the possibility of rotation around this axis K parallel to the I turn of the axis L. The upper part of the installed carriage 13 has a console 21, at the end of which it is installed with by turning the link 22, a copy bar 20 is guided in the link.
    Due to the swivel of the slider 15 with the crossbeam 14 and with the upper part of the carriage 13, the slider 15 and the grass Xca 14 can make swing movements along the arrow P. The shortening or lengthening of the arm 19 compared to the length shown in FIG. 2, the ram 14 slider tilts left or right along arrow P, which allows longitudinal movement of the tool with its axis tilted to the desired angle relative to the axis of the gear to be machined, with the result that the processed tooth profiles get some taper. With an increase in the angle between the tool feed direction and the axis M of the wheel being machined with a parallel or diagonal processing method, the efficiency of the slant position of the slide 15 and
    74
    cross member 14 decreases, i.e. as the angle of inclination increases, the taper decreases.
    To obtain a given taper when machining, for example, with a tangential tool feed, the machine is equipped with the device shown in FIG. 4 and 5.
    An axle 17 is installed in the upper part of the carriage 1J by means of self-aligning bearings 23 and 24, at one end of which an eccentric sleeve 25 is located between the upper part of the carriage 13 and the self-aligning bearing 23.
    At one end of this axis, a lever 26 of a known device for barrel-shaped processing of tooth profiles can be mounted. Traverse 14 is mounted on axis 17 by means of roller bearings 27 and 28. An eccentric sleeve 25 in the upper part of the carriage can be rotated at a small angle about the axis Q. For this purpose it is equipped with a gear segment 29 which interacts with a screw 30 mounted in a protrusion 31. As a result of rotation of the screw 30, the toothed segment 29, and therefore the eccentric sleeve 25 rotates, and the geometrical axis L of the axis 17 lowers or rises by the value of and. Simultaneously with the raising or lowering of this axis, the yoke 14 raises or lowers, carrying the tool head 7, i.e. The rotation axis F of the tool .8 is inclined. The angle of rotation of the eccentric bushing 25 is set on a scale of 32. When the axis 17 is raised or lowered due to the turning movement of the eccentric sleeve 25, the axis of the axis V is also displaced horizontally.
    Thus, the proposed machine design provides a tooth with a predetermined taper for various processing methods, regardless of the tool feed direction.
