Round positioning clamp and using method thereof

Abstract

The invention discloses a round positioning clamp and a using method thereof. The round positioning clamp comprises a first clamp, a second clamp, a regulating bolt and a plurality of pressing mechanisms, wherein the first clamp is fixedly arranged at one side of the upper part of a clamp base; the second clamp is arranged at the other side of the upper part of the clamp base in a sliding mode; the first clamp and the second clamp are symmetrically arranged, and are of semi-cylindrical structures; the first clamp is matched with the second clamp to form a clamp datum positioning circle; a partdatum circle of the processed part sleeves the clamp datum positioning circle; one end of the regulating bolt is connected to the second clamp, and the other end of the regulating bolt is connected to the clamp base; and the pressing mechanisms are uniformly arranged on the outer side periphery of the clamp datum positioning circle, and are used for vertical positioning of the processed part. According to the round positioning clamp disclosed by the invention, the first clamp and the second clamp define the clamp datum positioning circle; and the regulating bolt is screwed up to regulate a gap between the clamp datum positioning circle and the part processing datum circle, so that the precise positioning clamping effect on the processed part and a quick dismounting function on the processed part are realized.

Description

technical field [0001] The invention belongs to the technical field of positioning fixtures, in particular to a circular positioning fixture and its usage method. Background technique [0002] In the mechanical processing of parts, most parts cannot be completed through one process or one clamping process. The subsequent processing must be based on the previously processed parts and surfaces, so as to ensure the position of the processing surface in the previous and subsequent processes. requirements; at present, there are two ways to ensure that the process is relative to the reference: 1. Use the method of reference alignment; The method keeps the relative position of the datum consistent with the processing part, so as to ensure the relative position of different surfaces of the part; 2. The method of positioning fixture is adopted; the part datum is installed on the fixture positioning datum, so that the two datums coincide, so that the position on the fixture Datums ca...
