Description

Technical Field

[0001] The utility model relates to the technical fields of bracket welding and positioning tooling, and in particular to a bracket welding and positioning tooling. Background Art

[0002] Various types of brackets are often used in automobile chassis structural parts (such as front and rear subframes) to be welded to the main body such as the subframe, and various rods are connected by bolts for vehicle wheel alignment adjustment. There is a bracket used for adjusting the toe of the rear wheels. Its bolt mounting holes use waist-shaped holes. Brackets with waist-shaped holes are often used for positioning when welding to the main body of the subframe.

[0003] See Figure 1 and Figure 2 As shown, the conventional positioning method for bracket 30 is as follows: when welding parts, bracket 30 is first placed on positioning member 40 for simple positioning; then, positioning pin 20 is inserted from one side of the bracket. Positioning pin 20 has a tapered guide structure. When positioning pin 20 completely penetrates the waist-shaped hole of bracket 30, the part is in place and welding can begin. When the part is welded, the positioning pin 20 is pulled out of bracket 30 and the tooling with a pin puller 10, and the welded workpiece can be removed. However, due to welding deformation and shrinkage, the positioning pin 20 is difficult to remove after the bracket and subframe are welded, and there is a high probability of it getting stuck. A specially designed pin puller 10 is required to remove the positioning pin 20, which increases the time and labor intensity of the removal. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific implementations, but they are not intended to limit the present invention.

[0023] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size shall still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose of the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships shall also be considered as the scope of implementation of the present invention without substantially changing the technical content.
