Clamping device for special-shaped part inner hole grinding

Abstract

The invention discloses a clamping device for special-shaped part inner hole grinding. The clamping device comprises a square box, wherein the square box is of a hollow cuboid structure, a first through hole penetrating through the front end face and the rear end face of the square box is formed inside the square box, and the rear end face of the square box is connected with a grinding machine chuck through a bolt; a pressing plate is connected to each of the left side and the right side of the front end face of the square box, a first V-shaped groove is formed in each of the two sides, connected with the pressing plates, of the front end face of the square box, accordingly, a second V-shaped groove is formed in each of one faces, opposite to the square box, of the pressing plates, and when the two ends of the pressing plates are connected to the square box correspondingly, the first V-shaped grooves and the second V-shaped grooves are distributed oppositely; and one ends of the pressing plates are connected with the square box through connecting bolts, the other ends of the pressing plates are connected with the square box through supports, one ends of the supports are fixedly connected with the square box, and the other ends of the supports are hinged to the pressing plates. According to the clamping device, a special-shaped part to be machined can be clamped and positioned,so that the machining quality and the machining progress of the special-shaped part are ensured.

Description

technical field [0001] The invention relates to the technical field of special-shaped parts inner hole grinding, in particular to a special-shaped parts inner hole grinding and clamping device. Background technique [0002] There are a large number of special-shaped parts in the brake system and steering system of the automobile chassis. Most of these parts are cast and forged parts, which have the characteristics of complex structure and high processing precision. In mechanical processing, it is often divided into key and important parts by designers and craftsmen. Because of its various shapes, clamping, positioning, and processing are difficult, it is often identified as a key control process. At the same time, due to the long processing cycle, the input of spare parts is often increased to ensure the processing quality during production preparation, so as to ensure the production progress of the product. For this reason, the processing progress and processing quality of...

Problems solved by technology

[0003] Among them, for the special-shaped parts with inner holes, when the inner holes are ground, it is necessary to ensure that the parts to be processed have good stability, so as to ensure the processing quality and progress of the products, but in the prior art Due to the lack of corresponding clamping and positioning devices, when grinding the inner holes of special-shaped parts, there are often problems that the processing quality cannot be guaranteed and the processing progress is slow
