Fixture for grinding pressure casting

Abstract

The invention discloses a fixture for grinding a pressure casting. The fixture comprises a bottom plate; the bottom plate is vertically provided with a first side plate and a second side plate; the first side plate is horizontally and convexly provided with a first cylindrical pin towards the second side plate; the first cylindrical pin is matched with a round hole in one end surface of the pressure casting; the second side plate is provided with a locking mechanism comprising a first connecting plate, a second connecting plate, a push plate and a clamping plate; one end of the first connecting plate is connected to the second side plate through a first screw, and the other end of the first connecting plate is connected to one end of the second connecting plate through a movable screw; the other end of the second connecting plate is connected to the push plate through a second screw; the surface, close to the second side plate, of the push plate is fixedly provided with a slide block; the second side plate is horizontally provided with a guide rail; the slide block is arranged on the guide rail; the clamping plate is fixedly arranged on the push plate; the clamping plate is horizontally and convexly provided with a second cylindrical pin and a clamping block towards the first side plate; and the second cylindrical pin and the clamping block are matched with a round hole and a boss which are formed in the other end surface of the pressure casting. The fixture disclosed by the invention is precise in location, simple in clamping, suitable for large-scale processing of products and capable of increasing the production efficiency.

Description

Technical field [0001] The invention relates to a clamp device for grinding mechanical parts, in particular to a clamp for grinding die castings. Background technique [0002] At present, mechanical production and processing often need to polish the product. The usual method is that the operator holds the workpiece directly to polish, especially for the large and complex shape of the workpiece, which cannot effectively guarantee the consistency and standardized operation of the polishing. The labor protection effect is not good, thus affecting the quality of the product. The existing grinding fixtures for die castings generally need to be manually turned to adjust the direction, which is time-consuming and labor-intensive. [0003] Therefore, it is necessary to provide a better grinding clamp to solve the above problems. Summary of the invention [0004] In view of the problems in the prior art, the present invention provides a fixture for die casting grinding that is suitable for...
