The present invention relates to a clamping apparatus for a rolling roller bearing, and more particularly, to a rolling roller bearing clamp, which makes it easier and safer to combine or disassemble a clamp for holding a large rolling roller bearing on a roller shaft. It is about a device

Bearing bundles of large rolling rollers are used by fastening a circular clamp on the inner ring of the bearing to facilitate separate separation and disassembly to facilitate disassembly and coupling with the shaft.

Conventionally, the left and right semicircular clamps are opposed to each other and the bolts are fastened to each other for fixing.

However, as described above, the semi-circular clamps butt together are configured to be disassembled after the operator opens the clamps on both sides by hand.

In this process, the body of the bearing is coated with black lubricating oil on the whole parts, which contaminates the surrounding environment during disassembly and assembly, and at the same time, the clothes get oil on the clothes.

In addition, it takes a lot of time to disassemble and assemble the bolts, which requires a considerable amount of maintenance time. In particular, some bolts and nuts have a significant tightening force for use, which requires considerable labor for bolt disassembly.

In addition, if the quantity is large, in order to decompose within the fixed maintenance time, many people have to be put in. As a result, the labor cost should be increased due to the increase of the labor volume, and as a result, the production cost is showing a lot.

To solve this problem, according to Korean Patent Application Publication No. 2002-0071805 filed by the present applicant, the clamp insertion hole is formed in the clamp jaw, and the clamp bar of the automatic clamping device is inserted into the clamp insertion hole, The clamp bar is configured to move open and close so that the clamp can be automatically removed.

As can be opened and closed automatically as described above can reduce the contamination of the workplace and the productivity is reduced by reducing the working time.

However, in order to open and close using a clamp automatic opening and closing device as described above, the clamp bar must be correctly inserted into the clamp insertion hole of the clamp jaw.

The present invention has been made to solve the above problems of the prior art, by controlling the operation of the clamp jaws only by the lifting operation of the plunger to perform the coupling and release, the clamp bar into the clamp insertion hole as in the prior art It is an object of the present invention to provide a clamping device for a rolling roller bearing that can eliminate the inconvenience to be inserted, which can significantly shorten the working time.

In order to achieve the above object a first embodiment of the present invention,
