Embodiment 1

[0017] Embodiment 1 A kind of complex structure welding fixture

[0018] like Figure 2-4 As shown, a welding fixture with a complex structure includes a main body (1), a copper insert (2), a pressing plate (3) and a pressing screw (4).

[0019] The section of the red copper insert (2) is a U-shaped structure, one side profile of the main body (1) fits the inner wall of the U-shaped groove (5) of the red copper insert (2), and the pressure plate (3) and the red copper insert (2) ) connection, the compression screw (4) is threaded with the pressure plate (3).

[0020] The wall thickness of the copper insert (2) is 5mm.

Embodiment 2

[0021] Embodiment 2 Processing method of complex structure welding fixture

[0022] (1) Processing of the main body: After the planer processes the thick two sides of the main body (at this time, the thickness of the two sides is thickened by 10mm), the grinder grinds the thick two sides parallel, draws the contour line, and the milling machine processes the shape according to the line, and processes it with the copper insert 3-4mm allowance for CNC machining; after the fitter installs the tool board for CNC machining, use CNC machining for the main body shape, profile, and each step surface, CNC drilling and boring each hole, and then the fitter disassembles the tool board , Polish the surface of CNC machining.

[0023] (2) Processing of copper inserts: planer processes the thick two sides of the copper inserts parallel to each other (at this time, the thickness of the two sides is thickened by 10mm, which is equivalent to the wall thickness of the copper inserts being 10mm a...

Abstract

The invention relates to a processing method for a welding fixture with a complex structure. The welding fixture with the complex structure comprises a main body, a copper insert, a pressing plate and a compression screw, wherein the molded surface of one side of the main body is bound with the inner wall of a U-shaped groove of the copper insert; the pressing plate is connected with the copper insert; the compression screw is in threaded connection with the pressing plate. According to the processing method disclosed by the invention, the binding surface of the main body and the copper insert and the surface, bound with the main body, of the copper insert, are respectively and independently processed; at the time, the surface, bound with parts, of the copper insert, is not processed, so that machining allowance is reserved during integral processing, certain clamping allowance is reserved when the binding surface of the copper insert and the main body, and the processing intensity of the copper insert is improved; finally, the binding surface of the main body and the copper insert is ground; after the main body and the copper insert are assembled, the binding surface of the copper insert and the parts is integrally processed. According to the processing method disclosed by the invention, the difficult problem that the copper insert cannot be independently processed is solved; after the copper insert and the main body are integrally processed, the strength of the copper insert is improved, the convenience for processing is realized, and the processing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method of a welding fixture with a relatively complex structure. Background technique [0002] like figure 1 Shown is a part with a complex structure, the part is 1000mm long, 100mm wide, the aspect ratio is 10:1, and the structure is U-shaped. Due to the particularity of the structure, the quality of the parts cannot be guaranteed by conventional processing methods. Contents of the invention [0003] In order to solve the above problems, the present invention provides a welding jig for processing such parts. [0004] The technical solution adopted in the present invention is: a welding fixture with a complex structure, including a main body, a copper insert, a pressure plate and a compression screw. The inner wall of the block U-shaped groove is fitted, the pressure plate is connected with the copper insert, and the compression screw is threaded...
