Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig bracket with adjustable lateral distance. Background Technique

[0002] A jig refers to a device used to fix a processing object during the mechanical manufacturing process, so that it occupies the correct position to receive construction or inspection, also known as a fixture. Broadly speaking, any device used to quickly, conveniently and safely install a workpiece in any process of the technological process can be called a jig.

[0003] For the existing Chinese utility model patent with the reference publication number: CN208432389U, it discloses a jig bracket, which includes: a bracket body, a disk fixing block, a jig fixing disk, and a base; the jig fixing disk is connected to the disk fixing block pivotally connected to the bracket body, the bracket body is pivotally connected to the base, the jig fixing disk has a first pivot axis along its own axial direction relative to the disk fixing block, the disk fixing block has a second pivot axis relative to the bracket body, and the bracket body has a third pivot axis relative to the chassis, and the first, second, and third pivot axes are perpendicular to each other. The jig bracket of the utility model can conveniently adjust the three-dimensional angle, thus significantly improving the test efficiency and being beneficial to ensuring the accuracy of the test results.

[0004] During the welding process of two parts, it is necessary to fix the parts through a jig to ensure that the positions of the parts do not change during the welding process, so as to facilitate welding. The position of the jig of the existing jig bracket cannot be adjusted. When the center of gravity of the part deviates too much from the center of the jig, an included angle will be generated on the contact surface of the part, which affects the welding operation. At the same time, after the welding operation is completed, it is necessary to support the part before the jigs on both sides can be removed, which is very inconvenient. Content of the Utility Model
