Currently, the position of the clamping mechanism is fixed by pressing a knob on the side of the mounting base. However, this pressing method results in unstable fixing and causes the PCB circuit board to be clamped unsteadily. Therefore, this utility model proposes a PCB circuit board processing fixture. Utility Model Content

The mounting base is fitted onto the surface of the support mechanism, and bolts pass through both sides of the mounting base and the base. The bracket is fixed to the top of the mounting base, and the clamping component is disposed on the top of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By designing an adjustment component, the problem of unstable PCB board positioning is improved by addressing the issue of inconsistent PCB board positioning caused by the use of knobs to press the symmetrically arranged clamping mechanisms during PCB board processing and repair.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

The support mechanism 2 is composed of a rod A21 and a rod B22. The rod B22 is located at the end of the rod A21. An adjustment component is provided at the connection between the rod A21 and the rod B22. The adjustment component is composed of a limiting component 211, a movable groove 212, a stud 213, and a threaded groove 214. The rod A21 is adjusted by the adjustment component. The distance between the rods B22 is adjustable to accommodate the symmetrically arranged clamping mechanisms 3 during PCB circuit board usage. A movable slot 212 is located at the end of rod A21, and a threaded slot 214 is located at the end of rod B22. A stud 213 is located inside the movable slot 212 and the threaded slot 214. A limiting component 211 is located at the connection between one end of the stud 213 and the end of the movable slot 212. This adjustable component improves the previously inadequate clamping mechanism arrangement during PCB circuit board processing and repair, which required adjusting the distance between the symmetrically arranged clamping mechanisms. The distance between the clamping mechanisms 3 is fixed by pressing with a knob, which is somewhat unstable and causes instability in the position of the PCB circuit board. By setting an adjustment component between rods A21 and B22, the distance between the symmetrically arranged clamping mechanisms 3 can be adjusted to fix PCB circuit boards of different lengths. This improves the stability of the symmetrically arranged clamping mechanisms 3 after position adjustment while ensuring convenient adjustment operation. The stud 213 has a cylindrical structure, and the surface of the stud 213 is flush with the inner wall of the movable groove 212 and the threaded groove 21. The inner wall of the support mechanism 2 is fitted together. The diameter of the movable groove 212 is the same as the diameter of the threaded groove 214. The other end of the stud 213 is threadedly connected to the inner wall of the threaded groove 214. The clamping mechanism 3 consists of a clamping component 31, a bracket 32, and a mounting base 33. The mounting base 33 is fitted onto the surface of the support mechanism 2. The mounting base 33 and the base 1 are bolted together. Bolts pass through both sides of the mounting base 33 and the base 1. The bracket 32 ​​is fixed to the top of the mounting base 33. The clamping component 31 is located on the top of the bracket 32. The clamping component 31 consists of a locking block 311, a spring 312, and a fixing base 3. 13. The bracket consists of a fixing post 314, a locking block 311 located on the top side of the bracket 32, a fixing seat 313 located inside the bracket 32, and a spring 312 located between the locking block 311 and the fixing seat 313. The spring 312 has a certain elasticity to ensure that the distance between the PCB circuit board and the symmetrically arranged clamping mechanism 3 is such that even with a small deviation during installation, the PCB circuit board can be installed smoothly. The fixing post 314 is located on the side of the bracket 32, and the end of the fixing post 314 penetrates the bracket 32 ​​to press against the side of the fixing seat 313. The clamping assembly 31 is used to clamp the PCB circuit board.

[0021] In this embodiment, preferably, the limiting component 211 consists of a limiting rotating groove 2111 and a limiting rotating block 2112. The limiting rotating groove 2111 is opened at one end of the stud 213, and the limiting rotating block 2112 is disposed inside the limiting rotating groove 2111. The end of the limiting rotating block 2112 is fixed to the bottom end of the movable groove 212. The limiting component 211 connects the movable groove 212 and one end of the stud 213 through the limiting component 211, ensuring normal distance adjustment of rod A21 and rod B22. The surface of the limiting rotating block 2112 is in contact with the inner wall of the limiting rotating groove 2111, and the side cross-section of the limiting rotating block 2112 has a T-shaped structure.

[0022] The working principle and usage process of this utility model are as follows: During the processing and repair of the PCB circuit board, the PCB circuit board is fixed by a clamp. The PCB circuit board is placed between symmetrically arranged clamping mechanisms 3, and the two ends of the PCB circuit board are engaged by the locking blocks 311 to fix the position of the PCB circuit board. When the distance between the symmetrically arranged clamping mechanisms 3 is insufficient for the installation of the PCB circuit board, the distance between rod A21 and rod B22 is adjusted. First, a finger is inserted into the groove at the top of the threaded groove 214, and then the stud 213 is pushed to rotate inside the movable groove 212 and the threaded groove 214. Through the threaded connection between the stud 213 and the threaded groove 214, the distance between rod A21 and rod B22 is extended or retracted, completing the distance adjustment between the symmetrically arranged clamping mechanisms 3. This allows the clamp to fix PCB circuit boards of different lengths and sizes, facilitating subsequent processing and repair.
