Clamping tool

Abstract

The invention provides a clamping tool. The clamping tool comprises a base, a locating unit and a clamping unit; the locating unit comprises two parallel locating plates; the clamping unit comprises two clamping plates, one clamping plate is arranged at one end of the base, the other clamping plate is arranged at the other end of the base, the locating unit is located between the two clamping plates, the end faces, facing the locating unit, of the clamping plates are arc-shaped clamping faces matched with the outer walls of sleeves of a track plate, and the clamping plates are provided with power mechanisms capable of driving the clamping plates to move in the length direction of the base in a matched mode. The clamping tool aims to tightly clamp the outer walls of the sleeves of the track plate through the arc-shaped clamping faces of the two clamping plates, there is no requirement on the center distance between the two sleeves of the track plate, and therefore the problem that existing equipment cannot clamp or locate the track plate according to the machining requirement when the center distance between the two sleeves of the track plate is not consistent with a standard center distance is solved, the problems that the phenomenon that precision bored holes are eccentric or bored holes are not round occurs frequently when the sleeves undergo subsequent precision boring are solved, and waste is reduced.

Description

technical field [0001] The invention relates to a positioning device, in particular to a clamping tool. Background technique [0002] The track shoe is an important component of the crawler walking device. It consists of two cylindrical sleeves and a connecting plate connecting the two sleeves. This shape is very inconvenient for clamping and positioning. In the process of casting and molding, different batches often lead to inconsistent center distances between track shoe sleeves, and this inconsistency occurs randomly, so that the track shoe special fixture set in a fixed way using the existing clamping parts The effect of clamping and positioning the track shoes is not good, which leads to frequent phenomena such as fine boring eccentricity and out-of-round boring when the sleeve is subjected to subsequent fine boring processing, resulting in serious waste. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a clampin...

[0002] The track shoe is an important component of the crawler walking device. It consists of two cylindrical sleeves and a connecting plate connecting the two sleeves. This shape is very inconvenient for clamping and positioning.

However, in the process of casting and molding, different batches often lead to inconsistent center distances between track shoe sleeves, and this inconsistency occurs randomly, so that the track shoe special fixture set in a fixed way using the existing clamping parts The effect of clamping and positioning the track shoes is not good, which leads to frequent occurrence of fine boring eccentricity and out-of-round boring when the sleeve is subjected to subsequent fine boring processing, resulting in serious waste
