Track shoe positioning clamp

Abstract

The invention provides a track shoe positioning clamp. Four clamping grooves which are divided into two rows two by two with the central line in the height direction of a positioning plate as an axis are formed in the positioning plate; the distances from the axes of the clamping grooves in the same row to the central line in the height direction of the positioning plate are equal to each other; a fixed positioning block is fixedly arranged in one row of the clamping grooves in a clamped manner; a movable positioning block which can generate displacement in the length direction of a pedestal is movably arranged in the other row of the clamping grooves in a clamped manner; a supporting table is arranged below the fixed positioning block and the movable positioning block; a clamping plate is arranged at the position opposite to the central position of the end surface, where the clamping grooves are located, of the positioning plate; and the end surfaces, facing the clamping plate, of the fixed positioning block and the movable positioning block are in an arc shape. According to the track shoe positioning clamp provided by the invention, the distance between the fixed positioning block and the movable positioning block can be adjusted in a self-adaptive mode through the movable positioning block, and it is ensured that the outer wall of another sleeve of a track shoe is also positioned in the arc-shaped end surface of the movable positioning block, so that the track shoe positioning clamp has the advantages of improving the fine boring quality of a track shoe and the efficiency and reducing the cost.

Description

technical field [0001] The invention relates to a clamp, in particular to a track shoe positioning clamp. Background technique [0002] The track shoe is an important component of the crawler walking device, which consists of two cylindrical sleeves and a connecting plate connecting the two sleeves. The track shoe needs to go through the fine boring process to become a qualified part. The size between the clamping and positioning parts of the existing track shoe positioning fixture is fixed. This design has great limitations. For the same type of track shoe, In the process of casting and molding, different batches often lead to a certain error in the center distance between the track shoe sleeves, which makes the size of the workpiece and the fixture inconsistent, resulting in unstable clamping and positioning effects, prone to fine boring eccentricity, boring Holes are not round and other phenomena, resulting in increased scrap rate and increased production costs.
