Abstract

The invention relates to the field of mechanical engineering and can be used for grinding shaped parts. The purpose of the invention is to improve the accuracy of the device setup while simplifying its design. The device comprises a housing I, a rotary system 4 with a carriage 6 carrying the diamond holder 7, and a spring return mechanism consisting of a retaining ring fixed on the reversing system and a spring-loaded rod mounted on the carriage 6 and interacting with the retaining ring. When straightening, the diamond holder turns at a certain angle and moves progressively in a straight line at the extreme positions of the turning system. 4 il. "(L

The invention relates to mechanical engineering and can be used for grinding profile parts.

The aim of the invention is to improve the accuracy of the device settings while simplifying the design.

FIG. 1 shows the device; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 is an example of a grinding wheel profile.

The device consists of a housing 1, in which a yush is guided into a sleeve 2, in which a microscope 3 is located, whose optical axis is combined with the axis of a bearing of a sleeve. On the direction of yush, its sleeve has a rotary system consisting of a body 4 connected with a transverse rail 5, on which the carriage 6 with a diamond holder 7 is mounted for movement. On the right tool 8 there is a fixing ring 9. On the case of a rotary system Three separating sinus rollers 10 and a double-sided stop 11 are provided. The housing 1 has a groove in which rotation angle guides 12 are fixed and fixed with screws 13. A stopper 14 serves to fix the rotation system.

In the guide 5, there is a spring return mechanism comprising a stop ring 15 and a rod 16 having a cylindrical protrusion equal to the width of the stop ring. Spring-loaded thrust washers 17 are located on both sides of the protrusion. At the ends of the rod there is a handle 18 with a locking screw 19 and a handle 20, and a handle 21 is mounted on the body 4.

The housing 4 is connected to the guide 5 by means of the ring gear 22 and the rail 23. A compression spring 24 is mounted on the rod.

The device works as follows.

The vertical of the right instrument is combined with the optical axis of the microscope: in the horizontal plane with knobs 18 and 20, in the vertical plane with the help of the fixing ring 9. The radius of the right instrument 8 from the carriage 6 is adjusted using end gauges (not shown), extending

straightening corners (fig. 4) and are fixed by limiting the angle of rotation 12 when turning them until they come into contact with the stop 11.

The device is prepared for operation and installed on the machine table.

The grinding wheel is brought to the right tool so that its tip falls on the point O of the circle, the coordinates of which are determined with the help of a microscope 3. Rotate the handle 21 to fill the grinding wheel 10 radially.

On contact of the angle limiter 12 with the stop 1, the pivot system stops, the lath pair engages, and a smooth transition of the rotational movement into a straight line occurs. After editing Kpyi a, the guide carriage returns to its original position under the action of springs 24.

Using a microscope, the correctness of the grinding wheel is checked. 20 Thus, the proposed device, due to the adjustable rod spring return mechanism, ensures high tuning accuracy and high quality of editing of a single circle.
