Positioning fixture

Abstract

The invention discloses a positioning fixture. The positioning fixture comprises a positioning base, a first positioning unit and a second positioning unit, wherein the first positioning unit and thesecond positioning unit are arranged on the positioning base; the first positioning unit comprises a first clamping unit and a first supporting unit; the first clamping unit comprises a first inversely T-shaped support, a first movable table and a first clamp matched with the first movable table; one end of the first movable table is matched with the first clamp, a second inversely T-shaped support is provided with a second fixing frame, and the height ratio of the first inversely T-shaped support to the second inversely T-shaped support is (2-3):(1-1.5). According to the positioning fixture,the integral structural design is simple and reasonable, all components are matched with one another, the requirements of products can be met, and the function of supporting or clamping or positioningworkpiece components to be positioned and welded can be achieved so that the workpiece components to be welded can be attached point to point or face to face. After welding is finished by a welding fixture, the workpiece components are assembled into a complete workpiece through welding.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a fixture structure used in tack welding. Background technique [0002] In the traditional welding process, the welding of the workpiece to be welded is usually through simple cooperation between workers. Since the fixed clamping cannot be carried out stably, the stability and accuracy of welding cannot be guaranteed, and it directly leads to The production efficiency is low and the qualification rate of workpiece products is not high, which increases the difficulty of welding and labor costs, and cannot meet the needs of modern workpiece welding batch production, and the current positioning welding structure is relatively complicated, which makes it cumbersome to use and low production efficiency , increasing production costs. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of the prior art and provide a positioning fixture. [0004]...
