Problems solved by technology

Due to the complex structure of the fixture and the deformation after repeated high-temperature brazing, the size deviation of the positioning hole ⑥ leads to product quality problems
In addition, the self-weight of the fixture is 2.8kg, and the self-weight of the product is 1kg. Therefore, during the brazing process, the heat absorbed by the fixture (useless work) is higher than the heat absorbed by the product (useful work), resulting in energy waste; and the overseas procurement cycle is long, the cost is high, and the structure is complicated. , short life, low productivity in assembly and welding processes

Embodiment Construction

[0013] The present invention proposes a welding jig for an evaporator core. Be described below in conjunction with accompanying drawing.

[0014] exist Figure 2-5 In the schematic diagram of the new welding fixture shown, the upper and lower cover plates 1 of the welding fixture have the same structure and are made of channel steel. A clamp square opening 1-1 is opened at both ends of the channel steel bottom, and a square opening 1-1 is opened on both sides. Two card slots 1-2 (such as Figure 4 As shown in a, b, and c); among them, the connecting card bar 2 is placed in the card bar square opening 1-1, and the card slot 1-2 is stuck on the track 3-4 of the base 3, which plays the role of fixing the product. The two sides connecting clip 2 are fixed on the two ends of the connecting clip 2 by upper and lower stoppers 2-1 and upper and lower limit rings 2-2 (such as Figure 5 As shown), the clips on both sides clamp the upper and lower cover plates and the product to form ...

Abstract

The invention discloses a welding clamp for an evaporator core body, which belongs to the range of brazing auxiliary moulds. The welding clamp for the evaporator core body is formed by connecting an upper cover plate, a lower cover plate and two clamping strips on the two sides into a square frame, and fixing the clamping strips on the two sides to a base. A product is fixed in the frame and is placed in a welding furnace for welding. The welding clamp for the evaporator core body is simple in structure, low in cost, simple in assembly process and high in speed; the welding process efficiency is improved by 40 percent; and the service life of the clamp is prolonged to 3 to 5 years from 1 to 2 years.

Description

technical field [0001] The invention belongs to the scope of brazing auxiliary molds, in particular to a welding fixture used for the core of an evaporator. Background technique [0002] The welding fixtures of the existing automotive air-conditioning evaporators mainly play a supporting and fixing role in the brazing process. Because it is a foreign technology cited, more than 95% of the tools and molds are imported from abroad. figure 1 Shown is the original imported fixture, which is composed of chassis base ①; rear support bar ②; side support frame ③; upper pressure plate ④; support plate ⑤ and other parts. When using, take out the upper pressing plate ④, put the product ⑧ into the fixture and then put the upper pressing plate ④ on the product, press the upper pressing plate ④ down a certain distance through the assembly equipment so that the sliding bayonets ⑦ at both ends of the upper pressing plate ④ are inserted into the The positioning holes ⑥ on both sides of the ...
