Inner-hole processing clamp of thin-walled part for numerical control lathe

Abstract

The invention relates to an inner-hole processing clamp of a thin-walled part for a numerical control lathe. The inner-hole processing clamp comprises a clamp body arranged on the outer side of a workpiece to be processed, in a sleeving manner and fixed on the numerical control lathe and a clamp cover mounted at the front end of the clamp body and used for clamping the workpiece to be processed. During processing, the workpiece to be processed is inserted into the clamp body, and the clamp cover is fixed at the front end of the clamp body and tightly presses the front end of the workpiece to be processed. Compared with the prior art, the inner-hole processing clamp has the advantages that the clamp body is directly clamped by a three-jaw chuck, so that the clamp can be mounted convenientlyand quickly. After mounting of the clamp body, the clamp cover is screwed in to tightly press the workpiece for clamping. The inner-hole processing clamp is suitable for operations of various lengthsand wall thicknesses, and therefore, is strong in applicability. The workpiece to be processed is locked by the clamp cover, so that safe and reliable clamping is realized. The clamp cover is rotatedby a hook spanner for clamping, so that the operation is convenient.

[0002] At present, the inner hole processing of thin-walled parts has always been a major problem in the manufacturing industry. Because the wall is thin, it is not easy to clamp, and the clamping is easy to deform, the clamping force of the product is small, the processing efficiency is low, and the rigidity of the clamping of the parts is poor. , easy to produce vibrations that affect the surface quality of processed products and tool life

At present, boring soft jaws and elastic sleeves are basically used for clamping. The products clamped by soft jaws are easily deformed, and the inner hole becomes a triangle after processing. For parts with small inner hole tolerances, the scrap is extremely high.

Because the product wall is thin and the supporting force is poor, the clamping force is very small, the cutting parameters are very small during processing, and the efficiency is low

In addition, the elastic sleeve clamping method is often used to increase the rigidity of the product, but the elastic sleeve itself must have sufficient rigidity to ensure that it can be used for many times without deformation, but at the same time, the clamping force of the clamping sleeve itself is relatively large. Large, the clamping force is not easy to control when clamping the product

If the clamping force is too large, the product will still be deformed, if the clamping force is too small, it will not be clamped tightly, so the cutting parameters are still low during processing, and the product will have a high scrap rate due to the clamping force.

In addition, the current clamping methods are all radial clamping. For thin-walled parts, large deformation is inevitable. If the product has high precision, in addition to low efficiency, there are mainly high scrap rates and incorrect product clamping. Shortcomings
