Description

The invention relates to the abrasive machining of parts and can be used for grinding and polishing parabolic surfaces of rotation.

The aim of the invention is to improve the accuracy of processing.

FIG. Figure 1 shows schematically a device for grinding and polishing parabolic surfaces of rotation; in fig. 2 is a view A of FIG. one.

The cops 14 do not press on the springs 13 to the surface to be treated. The traverse of the lowering mechanism of the working member is fixed in this position and the drive is turned on, while the workpiece is set in rotation, the working member with RELIEF. And the cam 8 performs reciprocating oscillatory movements. To eliminate distortions of the rods 6 during operation, the cam 8 is mounted so that

The device consists of a body in which the pressure force coincides with the axis of the rods; the rum is fixed to the bearing 1 spindle 2; the rollers 9 are located in the forks with the dashboard 3, on which it is installed so that when the cam 8 turns

the workpiece 4, the working orga position of the minimum radius of the lever 5, the rods 6 with the springs 7, the cam 8 on the system of the working body 5 failed to drive the oscillating motion and the mechanical abrasive tools 14 to the axis of the working part 4 to lift and lower the workpiece 4. For ensuring the organ overrun (not shown).

The working body 5 consists of two levers pivotally connected at the point O, split the lever into two arms with a length L

and NL- The upper ends of the arms pivotally connecting the oscillatory movement of the abrasive indices at points B with rods 6, on which the parts are machined, the springs 7 are attached and fixed to the Regulator by driving the frequency of yours

rollers 9. The rods are installed with an optional-machined part and oscillatory

By mixing in the direction of abrasive tools, it is possible to choose the spindle of the part, in the direction of 35 to provide the necessary accuracy and quality bearings 10, eliminating the rotation of processing.

for the axis of the workpiece abrasive tools have sharpened the front face. Due to the joint rotational movement of the workpiece and the reciprocal of the invention. A device for grinding and polishing the rods around its axis. The lower ends of the arms of the working body have adjustable links 11 with locking screws 12. On adjustable links, there are springs 13 with abrasive tools of parabolic surfaces by the rods 14. and there is a housing with a rotating spindle mounted in it

The device works as follows and working body, made in the form

a hinged arm interconnected to each other. The workpiece 4 is fastened to the tongues associated with the oscillating drive.

on faceplate 3. A given 35 motion is set in the form of a cam and carriers on

Adjustable links for fastening abrasive tools, characterized in that, with the aim, my links 11 are pulled out at the lower ends or the accuracy of processing is increased, the device

at K 1, they are moved to the required length and are fitted with the K y coefficient installed in the housing, for which the i

they are fixed in this position with locking screws 12. The setting of the K coefficient is controlled by reference lines located on the adjustable links. Then, the tool body with the help of a reciprocating movement in the direction perpendicular to the axis of the product spindle, spring-loaded rods with rollers, while the upper ends of the arms are pivotally connected with lowering and lifting stonism, and the rollers are set down as long as the abrasive tool-contact with the actuator cam.

the working tool system 5 brought the abrasive tools 14 to the axis of the workpiece 4. To ensure the overrun

the oscillatory motion of abrasive tools, the part is machined;

for the axis of the workpiece abrasive tools have sharpened the front face. Due to the joint rotational movement of the workpiece and the reciprocal of the invention, a device for grinding and polishing parabolic surfaces has a retractable housing with a mounted reciprocating movement in the direction perpendicular to the spindle axis of the product, spring-loaded brushes with rollers, while the upper ends of the arms of the hinge are connected with stock
