Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a welding jig for a fuel filter bracket. Background Art

[0002] An automotive fuel filter is a device for purifying fuel. The automotive fuel filter is connected to the pipeline between the fuel pump and the fuel inlet of the throttle body. The function of the automotive fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel, prevent blockage of the fuel system, especially blockage of the fuel injector, reduce mechanical wear, ensure stable operation of the engine, and improve reliability. Currently, the bracket assembly for an automotive fuel filter generally consists of a main bracket and a C-shaped pipe clamp bracket. It is fixed to the corresponding position on the vehicle body by passing bolts through the mounting holes of the main bracket, and then the fuel filter is locked to the bracket assembly through the C-shaped pipe clamp bracket and bolts and nuts.

[0003] The C-shaped pipe clamp bracket generally has two ear structures, and a gap is reserved between the two ear structures for reserving a clamping space for the installation of the fuel filter. In order to facilitate the clamping and assembly of the C-shaped pipe clamp bracket to the fuel filter, in the prior art, a nut is welded to one of the ear structures. Due to the reserved gap between the two ear structures, the ear structure will shake during the welding process, resulting in easy occurrence of conditions such as false welding and welding deviation when welding the nut. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of easy occurrence of false welding and welding deviation when pre-installing and welding nuts on the C-shaped pipe clamp bracket in the prior art, and to propose a welding jig for a fuel filter bracket.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A welding jig for a fuel filter bracket, the fuel filter bracket includes a main bracket and a C-shaped pipe clamp bracket. The two ends of the C-shaped pipe clamp bracket respectively extend with a first ear part and a second ear part. The first ear part and the second ear part both have mounting through holes. A buffer gap is provided between the first ear part and the second ear part. One side of the C-shaped pipe clamp bracket extends with an extension part along its axial direction, and the end of the extension part extends with an axis limiting part. The welding jig includes a bottom support, and a first vertical clamp and a second vertical clamp capable of abutting the main bracket and the C-shaped pipe clamp bracket together are installed on the bottom support;

[0007] A third vertical clamp and a horizontal support assembly are installed on the bottom support. The fuel filter bracket includes a nut. One side of the nut abuts against the first ear part, and the other side of the nut abuts against the chuck of the third vertical clamp. At least part of the horizontal support assembly supports on the side of the first ear part away from the nut.

[0008] The horizontal support assembly includes a first support rod arranged horizontally. The first support rod is horizontally and slidably connected to the bottom support. One end of the first support rod close to the C-shaped pipe clamping bracket is fixedly connected with a support plate. Sliding the first support rod can make the support plate insert into the buffer seam and support on the side of the first ear away from the nut.

[0009] There is a stepped surface between the support plate and the end of the first support rod. When the support plate supports on the side of the first ear away from the nut, the stepped surface abuts against the end face of the first ear.

[0010] The first support rod is a first cylindrical rod. The bottom support is provided with a first round hole and a second round hole. The first support rod slidably penetrates through the first round hole. A second support rod is slidably inserted into the second round hole. The second support rod is a first cylindrical rod. The first support rod and the second support rod are fixedly connected by a connecting plate.

[0011] The bottom surface of the main body bracket supports on the bottom support. The axis of the C-shaped pipe clamping bracket is horizontally arranged. Part of the outer peripheral surface of the C-shaped pipe clamping bracket abuts against the main body bracket. Part of the main body bracket is clamped between the chuck of the first vertical clamping device and the bottom support. Part of the extension part is clamped between the chuck of the second vertical clamping device and the bottom support.

[0012] The bottom support has a limit block. The axis limiting part abuts against the limit block.

[0013] A fuel filter bracket welding tooling proposed by the present utility model has the beneficial effects that: this device stably supports the first ear and the nut between the horizontal support assembly and the third vertical clamping device, avoids the shaking of the first ear when welding the nut, effectively reduces the probability of false soldering or welding skew when welding the nut, and improves the yield rate.

Then, one side of the nut 8 is abutted against the first ear part 5 by the third vertical clamp 11, and at the same time, it is supported on the side of the first ear part 5 away from the nut 8 by the horizontal support assembly 13.
