Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, in particular to a fixture for fixing a power amplifier board. Background Art

[0002] With the continuous development and refinement of the current electronic product production and maintenance field, the power amplifier board, as a key component in electronic equipment, is particularly important in the fixation and operation of the production and maintenance process.

[0003] Generally speaking, after the fixture firmly clamps the power amplifier board, it can no longer make any adjustments to the angle of the power amplifier board, which causes great inconvenience and limitations in actual production and maintenance work. When the power amplifier board needs to be welded, tested or debugged at a specific angle, the traditional fixing fixture cannot meet these complex and diverse operation requirements due to its fixed angle limitation. This will not only lead to a significant reduction in work efficiency, but also may affect the accuracy and precision of the operation because the ideal operating angle cannot be achieved, which will have an adverse effect on the quality and performance of the product. For this reason, we propose a power amplifier board fixing fixture. Utility Model Content

[0020] Please refer to Figure 1-2 As shown, the utility model provides a power amplifier board fixing fixture, including a mounting plate 1, a slide groove 14 is provided on the surface of the mounting plate 1, a slider 3 is slidably installed inside the slide groove 14, an adjustment component for driving the slider 3 to move is installed on one side of the mounting plate 1, and a first clamping plate 4 is rotatably installed on one side of the slider 3;

[0021] A second clamping plate 7 opposite to the first clamping plate 4 is rotatably mounted on the top surface of the mounting plate 1. Grooves for clamping the power amplifier board are provided on the surfaces of the first clamping plate 4 and the second clamping plate 7. A friction assembly for resisting the second clamping plate 7 is installed on one side of the mounting plate 1. The friction assembly is used to fix the angle of the second clamping plate 7.

[0022] Specifically, after the fixation of the second card plate 7 is cancelled by the friction component, the angle of the power amplifier board can be changed by rotating the second card plate 7 and the first card plate 4. Then, the angle of the second card plate 7 is fixed by the friction component, so that the angle of the power amplifier board can be fixed, and its adjustment is more convenient.

[0023] Among them: a plurality of through holes 2 are opened on the surface of the mounting plate 1, which reduces the area of ​​the first clamping plate 4 and the second clamping plate 7 contacting the mounting plate 1 in a horizontal state, slows down the heat conduction of the jig, and effectively prevents the need to spend longer heating time when heating the power amplifier board and placing components.

[0024] Wherein: the adjustment component includes a first threaded rod 5, the first threaded rod 5 threads through the mounting plate 1, one end of the first threaded rod 5 is rotatably mounted on one side of the slider 3, and the other end of the first threaded rod 5 is fixedly mounted with a first knob 6. By rotating the first knob 6, the first threaded rod 5 is driven to rotate, thereby driving the slider 3 to slide inside the slide groove 14.

[0025] Wherein: the friction assembly includes two telescopic rods 8, one end of the outer rod of the telescopic rod 8 is fixed to one side of the mounting plate 1, one end of the inner rod of the telescopic rod 8 is fixedly installed with a moving plate 9, an L-shaped connecting rod 10 is installed on the top surface of the moving plate 9, and one end of the L-shaped connecting rod 10 is fixedly installed with a friction plate 11 for resisting the second clamping plate 7, and one side of the mounting plate 1 is installed with a threaded assembly for driving the moving plate 9 to move, the threaded assembly includes a second threaded rod 12, the second threaded rod 12 is rotatably installed on one side of the mounting plate 1, the second threaded rod 12 threads penetrate the moving plate 9, and one end of the second threaded rod 12 is fixedly installed with a second knob 13, and the second threaded rod 12 is driven to rotate by rotating the second knob 13, thereby driving the moving plate 9, the L-shaped connecting rod 10 and the friction plate 11 to move.

[0026] Working principle: The utility model is a fixture for fixing a power amplifier board.

[0027] The first card plate 4 and the second card plate 7 can both rotate. When the angle of the power amplifier board needs to be adjusted, the second threaded rod 12 is driven to rotate by rotating the second knob 13, thereby driving the movable plate 9, the L-shaped connecting rod 10 and the friction plate 11 to move. The friction plate 11 does not interfere with the second card plate 7, so that the second card plate 7 and the first card plate 4 can rotate together with the power amplifier board. Subsequently, the second knob 13 is rotated in the opposite direction, so that the friction plate 11 and the second card plate 7 are in friction with each other, and the second card plate 7 is fixed by friction force, so that the positions of the second card plate 7, the power amplifier board and the first card plate 4 are fixed, so that the angle of the power amplifier board is fixed, so that it is convenient to adjust the angle of the power amplifier board when the power amplifier board is clamped, so that it is convenient to operate at a specific angle, thereby improving the flexibility of the use of the fixture.
