Aluminum alloy welding drilling hole positioning fixture

Abstract

The invention provides an aluminum alloy welding drilling hole positioning fixture, which comprises a base, positioning discs, and a machined workpiece. The left side and right side of the base are axially connected with a set of positioning discs correspondingly, and a set of rotating corner working tables are connected between the two sets of positioning discs in a hinged mode. The aluminum alloy welding drilling hole positioning fixture adopts the rotating corner working tables provided with plug pins, the included angle of the rotating corner working tables can be adjusted during using, welding of aluminum alloy plates with different angles can be realized, the aluminum alloy welding drilling hole positioning fixture is good in adaptability and is widely used, at the same time rotationof the positioning discs is realized by using a material worm driving machine, the machining angle of the machined workpiece can be arbitrarily adjusted during using, welding operation and drilling hole machining are convenient to perform, the good machining angle is provided, the machining accuracy is provided, at the same time, one time loading clamping can be realized to complete welding, holedrilling and other all processes, the error caused by multi-time loading clamping is avoided, the machining accuracy is improved, loading clamping times are decreased, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machining, welding and drilling positioning, and more specifically relates to an aluminum alloy welding and drilling positioning fixture. Background technique [0002] In mechanical processing, it is often necessary to weld two sets of aluminum alloy plates at a certain angle. When welding aluminum alloy plates, it is necessary to fix the two sets of aluminum alloy plates to facilitate welding. Welding tools are generally used when fixing aluminum alloys. to fix. [0003] For example, application number: CN201621150232.6 An angle steel tower foot welding tool of the present invention includes a bottom plate, four non-intersecting vertical plates are arranged on the bottom plate, and the central extension lines extending from the four vertical plates to the center of the bottom plate intersect at one point and The angle between two adjacent central extension lines is a right angle, and a movable splint is...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an aluminum alloy welding drilling positioning fixture to solve the problem that the installation angle of the parts of the existing welding tooling is generally fixed. When welding at other angles is required, the requirements cannot be met, and the tooling needs to be replaced , the adaptability is not high, and the cost of use is high. At the same time, the welding workpiece is fixed. During use, welding on both sides will cause vertical welding or overhead welding. Increased welding is prone to welding quality problems. At the same time, there will be problems after welding. Subsequent processing operations such as drilling and welding need to be re-clamped. Re-clamping is likely to cause errors and affect processing accuracy. Multiple clamping affects production efficiency.
