A kind of jig integrated with boring and drilling of chain rail link

Abstract

The invention provides a caterpillar track section boring and drilling integrated clamp, and belongs to the technical field of clamps of machining machines. The caterpillar track section boring and drilling integrated clamp comprises a rotatable rotary table provided with a bottom plate and a clamp. The clamp comprises two sets of cushion blocks, locating structures, a plane pressing structure andvertical pressing structures. Each locating structure comprises a shaft end side locating plate, a tread side locating block and a sliding block, wherein the tread side locating block and the slidingblock are arranged on the two sides of the corresponding set of cushion block correspondingly. The plane pressing mechanism acts on the sliding blocks, and the vertical pressing structures act on to-be-machined caterpillar track sections. The caterpillar track section boring and drilling integrated clamp can be used for vertical machining equipment machining through the rotatable rotary table, and no special machine needs to be ordered; the two caterpillar track sections can be clamped by the clamp at the same time, rough boring, fine boring and drilling machining can be completed through one-time clamping, the machining efficiency is high, and the cost is low; locating and pressing assemblies at the adjustable positions are arranged, machining on products of different types is achieved,and adaptability is higher; and the structure is simple, demounting and mounting are convenient, the manufacturing period is shorter, and later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of clamps for processing machines, in particular to a chain rail link boring and drilling integrated clamp. Background technique [0002] Many construction machinery are equipped with crawlers, and the chain link is the main component of the track. Boring holes on the chain link are used to assemble shafts and sleeves, and the processing quality of the link will directly affect the connection strength of the link. Therefore, , the processing of chain rail joints is the focus of current research. [0003] At present, the horizontal special machine is used to process the shaft hole and the casing hole at the same time for the processing of the chain rail section. Since the pitch span of different types of chain rail sections is large, the selection of the boring head of the equipment is affected by it, and only the pitch span is not large. It is impossible to process special types of chain rail links; at the ...

Problems solved by technology

[0003] At present, the horizontal special machine is used to process the shaft hole and the casing hole at the same time for the processing of the chain rail section. Since the pitch span of different types of chain rail sections is large, the selection of the boring head of the equipment is affected by it, and only the pitch span is not large. It is impossible to process special types of chain rail links; at the same time, the investment cost of custom-made special equipment and fixtures is high, and the production cycle is long, which is only suitable for the production of conventional models.

[0004] To sum up, the current special fixtures for chain rail links are only suitable for special boring machine equipment, and the investment cost is high, the production cycle is long, and it cannot adapt to the processing of special types of products, and the adaptability is poor.
