Description

Technical Field

[0001] The utility model relates to the technical field of test fixture structures, in particular to an electronic component test fixture. Background Art

[0002] Electronic components are components of electronic elements and small machines and instruments. They are often composed of several parts and can be used in similar products. The produced electronic components need to be tested, such as micro motors and electronic transformers, to ensure product quality.

[0003] The existing test requires personnel to test the electronic components one by one by powering on them. The personnel place the electronic components in the corresponding fixture room. When the test fixture clamps and fixes the electronic components to be tested, the test fixture itself is displaced by manual or pneumatic adjustment. There is no buffer structure in the clamping process. When the distance of the fixture displacement exceeds the standard, it is easy to cause surface damage to the electronic components to be tested, affecting the quality of the electronic components. Therefore, an electronic component test fixture is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

By embedding the rectangular block end of the movable shaft inside the limiting groove of the docking plate, the movable shaft can be prevented from detaching from the inside of the docking plate during outward pulling.

[0008] Preferably, the side of the rubber plate is connected to a rubber sleeve, and the rubber sleeve is arranged on the outside of the docking plate, so that the movable shaft and the buffer spring can be blocked by the rubber sleeve.

[0009] Preferably, two slide rails are installed at the bottom end of the movable plate through bolts, and the slide rails are embedded in the interior of the mounting seat through slide grooves. The slide rails slide in the slide grooves of the mounting seat to change and adjust the position of the movable plate.

[0010] Preferably, the back of the movable plate is connected to a connecting plate, and a threaded shaft is inserted into the top of the connecting plate through a threaded hole. The axial end of the threaded shaft is inserted into the surface of the mounting seat through a groove. After moving, the axial end of the threaded shaft can be inserted into the groove of the mounting seat to ensure the stability of the movable plate after adjustment.

[0011] Preferably, a pallet group is installed on the front of the movable plate, and the pallet group includes a bracket, and a fixing bolt is connected to the front of the bracket. The front of the bracket is docked and fixed to the movable plate through a sponge drag, and the fixing bolt can be extended through the bracket so that the fixing bolt can support the arm of the staff.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting a clamping assembly, clamping and buffering of electronic components can be achieved. Compared with the traditional structure, the device can push the docking plate to move through the extension and retraction of the output end of the cylinder. During the movement of the docking plate, it can cooperate with the rubber plate to clamp the electronic components. During the clamping process, the rubber plate is subjected to force to push the movable shaft to move inside the through hole of the docking plate, and then the buffer spring is compressed and deformed. The rebound force of the buffer spring generates a rebound interval, which can prevent the surface of the electronic component from being damaged due to the extension and retraction transition of the output end of the cylinder, thereby improving the safety of electronic component testing.

[0015] 2. By setting up a movable component, the displacement adjustment of the clamping component can be achieved. The device moves in the rail groove of the mounting seat through the slide rail, and the position of the movable plate can be adjusted so that the clamping component after adjustment can meet the usage needs of workers at different workstations. At the same time, the shaft end of the threaded shaft can move in the threaded hole of the connecting plate, and then the shaft end of the threaded shaft is pressed against the inside of the groove on the surface of the mounting seat to ensure the stability of the movable plate after adjustment.
