CS243320B1 - Lapping palette for bonding roller bearing faces - Google Patents

Abstract

By adjusting the working position to the filling-transport position and back to the required position, the rollers can be filled into the pallet outside the lapping machine. It consists of two rotary discs connected to each other and provided with an indexing device for fixing the required position, which is achieved by rotating the lower disc so that the roller openings cover or only partially overlap.

Description

The invention relates to a lap-shaped construction. pallets for lapping NNK bearing roller faces on lapping machines.

Lapping is carried out, for example, on a Hahn Kolb lapping machine in six pallets per operation, with a number of rollers from 90 to about 400 pieces. The lapping pallets are placed on the bottom lapping disc in the machine and the rollers are inserted into the holes in the lapping pallets by the operator.

With the upper lap disc, the lap pallet is lowered and the machine is lowered for about 10 minutes. After the operation is completed and the upper lap disc is lifted, the operator also lifts the lap pallet, the rollers remain on the bottom lap disc and collapse into the hopper.

This cycle must be repeated as the pallets cannot be filled outside the lapping machine. The machine is not running while the pallet is being filled and the operator is not used again during the lapping operation. When filling the lapping pallets in the machine, the operator still has to be inclined over the machine during this work, which are undesirable and physically strenuous movements for women who mostly work on these operations.

These drawbacks are solved by the construction of the lapping pallet according to the invention, which is provided with two rows of holes for receiving and guiding the rollers and with circumferentially generated toothing. It is an object of the present invention that the lapping pallet consists of two discs joined to one another in a bayonet manner and that the lower disc is rotatably mounted in a circular recess of the upper disc. The depth of the recess is the same as that of the lower disc. Both discs have a centering hole and are provided with an indexing device.

By using the new lapping pallet according to the invention, the lapping operation is achieved by reducing the operation of the lapping machine. Also, the operation time has been considerably shortened, eliminating operator downtime and unwanted working attitude when loading pallets in the machine.

The lapping pallet according to the invention is shown in the attached drawing, in which Fig. 1 is a lapping pallet assembled, Figs. .

The lapping pallet 6 according to the invention consists of discs 6 and 6 which are centered by means of a centering hole 4. They can be pivoted relative to each other since they are connected by a bayonet connection 8. The disks 12 and 16 are circumferentially provided with a toothing 6, which fits into the pin rim of the lapping machine rolling device.

Two rows of holes 4 for receiving and guiding the rollers are drilled in the disc 21. The disc 6 has a recess 6, in which the disc 6 is mounted. The disc 6 has an indexing device 6.

In working position; 10, the roller holes 6 are covered. In the filling-transport position, the lapping pallet 6 is adjusted by rotating the disc 6 so that the holes 6 do not cover, the rollers cannot fall out and are filled into the lapping pallet 6 on a mechanical filling device. The position of the working 10 and the position of the filling-transporting 9 are provided by the indexing device 6.

With lapovací! With the pallets 1 according to the invention, the operator operates as follows. It fills 6 pcs of lapping pallets 6, which are fixed in the filling-transport position 6 by the indexing device 5 on the mechanical filling device.

Then, the filled lapping pallets 6 are rollers, still in position 6, placed on the bottom lapping disk of the lapping machine so that they fit into the pin rim of the lapping machine rolling device and, by means of the indexing device 8, bring the lapping pallets into position 10.

The upper lapping disc tilts the lapping pallet 1 and the machine is lowered to lapping. During the lapping operation, the operator fills the reserve lapping pallet 6 on the mechanical filling device. After lapping, the operator lifts the lapping disk and lapping pallet 6, bringing it into position 6 by the indexing device 6 and depositing it on the mechanical filling device. The rollers that remain on the lapping machine are packed into a magazine and loaded into the machine by the filled pallets 6, brought into position 10 and lowered. The whole cycle is repeated.

The lapping pallet according to the invention achieves a standard-hour saving and improvement of the workplace in terms of hygiene and ergonomics when lapping the roller faces on the lapping machine. Usage is. possible eg in the consumer industry.
