[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A B-pillar error-proof welding fixture includes a support seat 1, a clamping assembly 2 connected to the top of the support seat 1 to press the B-pillar on the support seat 1, and a positioning detection device 3 connected to the support seat 1 by bolts. The utility model is used to detect whether there are leak holes or leak grooves in the B-pillar after punching and cutting in the previous process, and assist in locating the corresponding position of the B-pillar in the fixture.

[0021] The positioning detection device 3 includes a mounting block 301, which includes a fixing portion connected to the support seat 1, an extension portion is provided at the end of the fixing portion, and the extension portion is bolted to a detection block 302. Through the combination of different shapes of the fixing portion and the extension portion, the detection block 302 is sent to the detection position of the B-pillar workpiece.

[0022] The fixing part and the extension part of the mounting block 301 are arranged in a straight line, the top surface of the extension part is arranged perpendicularly to the side surface of the fixing part, and the detection block 302 is connected to the top surface of the extension part. That is, when the detection position of the B-pillar is located near the bottom surface of the support seat 1, and the plane where the slot or hole to be detected is located is perpendicular to the vertical direction, the detection block 302 is directly inserted upward into the detection position.

[0023] The fixed part and the extension part of the mounting block 301 are arranged in a straight line, the top surface of the extension part is not arranged perpendicularly to the side surface of the fixed part, and the detection block 302 is connected to the top surface of the extension part. That is, when the detection position of the B-pillar is located near the bottom surface of the support seat 1, but the plane where the slot or hole to be detected is located is at an angle to the vertical direction, the top surface of the extension part is arranged parallel to the plane where the slot or hole to be detected is located, and the detection block 302 is inserted obliquely into the detection position.

[0024] The fixing part of the mounting block 301 is set at an obtuse angle to the extension part, and the detection block 302 is connected to the outer side of the extension part. That is, when the detection position of the B-pillar is far away from the bottom surface of the support seat 1, and the plane where the slot or hole to be detected is located is at a certain angle to the vertical direction, the length of the extension part extends to the position to be detected, and the detection block 302 is connected to the outer side of the extension part and is obliquely inserted into the detection position.

[0025] The fixing part of the mounting block 301 is arranged at a right angle to the extension part, and the detection block 302 is connected to the inner side of the extension part. That is, when the groove to be detected is located on the side of the B-pillar, the extension part extends upward, bypasses the B-pillar body, and the detection block 302 is connected to the inner side of the extension part and protrudes inward to be inserted into the detection position.

[0026] The clamping assembly 2 includes a rotating block 201 rotatably connected to the support seat 1, the rotating block 201 is fixedly connected to a connecting block 202, and a clamping block 203 is fixedly connected to the connecting block 202. The rotating block 201, the connecting block 202 and the clamping block 203 are all provided with at least one threaded hole. When more than two threaded holes are provided, the clamping assembly 2 can change the position of the clamping block 203 to adapt to more specifications of B-pillar workpieces to be processed.

[0027] At least one support base positioning block 101 is disposed in the support base 1 .

[0028] Working principle: According to the detection position of the B-pillar to be processed, a positioning detection device 3 composed of a suitable fixing part and an extension part is selected, and the positioning detection device 3 is installed in the support seat 1. When the B-pillar after punching and cutting is placed in the support seat 1, the side with a groove on the side of the B-pillar is placed in the support seat 1 first, and the other side is placed later. When the groove on the side of the B-pillar is not opened or opened misaligned, the side placed later will not be able to be placed smoothly, and this B-pillar is judged to be a defective product. When the bottom surface of the B-pillar is blocked and cannot be placed in the support seat 1, it is judged that there is a leaking hole on the bottom surface of the B-pillar or the hole is misaligned. That is, when the B-pillar can be placed in the support seat 1, it is a qualified product, and when the B-pillar cannot be placed in the support seat 1, it is a defective product.
