Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The position of the positioning block in the device is fixed, and it can only be adapted to clamp circuit boards with a fixed width, and the scope of application is very limited; 2. The device The clamping adjustment process is relatively rough, which is easy to cause damage to the circuit board with high precision, and lacks a device that can perform fine-tuning operations

Abstract

The invention discloses a clamping device for a lifetime test of a circuit board. The clamping device comprises a fixed operation panel, the fixed operation panel is provided with a guide rail, the guide rail is provided with a recessed groove, a first clamping block is movably arranged in the recessed groove, a T-shaped connecting block is fixedly connected to a screw rod, one end, far from the T-shaped connecting block, of the screw rod is fixed to the center of a worm wheel in a penetrating manner, the worm wheel is movably arranged on a worm, the screw rod is movably provided with a nut base, and the nut base is fixedly provided with a second clamping block. According to the clamping device for the lifetime test of the circuit board, circuit boards of different specifications can be stably clamped, the application range is wide, coarse tuning and fine tuning can be respectively performed through the built-in first clamping block and the second clamping block, the refinement degreeis high, and lossless clamping of the circuit boards with high precision can be realized.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a clamping device for circuit board life testing. Background technique [0002] The devices in the circuit board are developing in the direction of miniaturization and pin spacing, and the demand and difficulty of testing the circuit board are also increasing. The traditional clamping device for circuit board life testing can only adapt to fixed-sized circuits. PCBs lack universality for circuit boards with different specifications and shapes. At the same time, the fixing of the circuit board by the clamping device is relatively rough, which is easy to cause damage to the circuit board. Therefore, for circuit boards with high precision, there is an urgent need for a Clamping device capable of fine-tuning and fixing. [0003] In the prior art, a circuit board test fixture with the application number "201720739929.5" includes a substrate, and the substrate is equipped wi...
