(5) DEVICE FOR CLEANING AND HARDENING TREATMENT OF SURFACE DETAILS

I

The invention relates to metal working, in particular to devices for rolling outer surfaces. , details such as rotation bodies.

A device for finishing and hardening the outer surfaces of rotation is known, in the case of which a forked holder is hingedly mounted, carrying deforming elements arranged at an angle to one another in its swing plane tl.

. A device is also known with two rollers mounted in a rotatable spring-loaded holder, which provides continuous processing of cylindrical surfaces and fillets 2.

The disadvantage of this device. It is necessary to rearrange it in the support of the machine when machining the end surface, which reduces the productivity of the operation.

The purpose of the invention is to increase productivity when processing the ends of the fillets and cylindrical surfaces of parts such as coils.

This goal is achieved by the fact that the device is equipped with two spring-loaded plungers, equidistant from the axis of the mandrel and designed to interact with the end of the holder, the latter being installed with the possibility of moving the axle of the housing.

FIG. 1 shows the proposed device when installed on a machine; FIG. 2 shows a device, a sectional view, in FIG. 3, section A-A in FIG. 2

In the mandrel 1, a fork 2 is installed, which with the help of pins 3 is secured against falling out and is prevented from rotating around its axis with the help of two tangential clamps t with nuts 5B, the fork 2 is inserted into the holder 6, in the slots of which x 2 in the bearings 8 are mounted knurling 939 The holder 6 is fixed by the axis 10 and its end surface is supported on two plunger 11 pressed against it by spring 12. The spring force is adjusted by screws 13. The covers Il and 15 prevent the bearings from axial mixing. The device works as follows. The mandrel 1 is attached to the tool holder of a lathe. The right roller touches the maximum diameter of the right end of the coil to be machined, the required rolling force is established along the longitudinal feed vernier (previously ottirovanny). In this case, the holder, deflected to the left, rotates around the axis 10 VI and receives the force of the plunger 11. The rotation of the part and the lateral flow of the machine are turned on. After machining the end face and the fillet, the cross feed is turned off, the longitudinal feed of the machine is turned on and the cylindrical surface of the coil is rolled. In this case, both rollers come into play, and the processing force is perceived by two plungers. Then, the left end of the coil is processed in the same manner. The proposed device provides consistent processing.
