Problems solved by technology

The current traditional approach, such as figure 1 As shown, there are many small holes on the bottom plate of the jig, and the power module is inserted into the hole to fix it. The size and arrangement of the holes are determined by the power module, but the height of the jig cannot be adjusted, and it can only be used to detect power modules of the same height. , the same fixture can only be applied to modules of the same height, so the fixture cannot be widely used, and different heights require different fixtures, which is also a waste of cost

Embodiment Construction

[0013] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0014] The invention provides an adjustable height-limiting jig, where the component to be tested refers to an assembled switching power supply module. Such as figure 2 As shown, it includes a jig base 1, two guide posts 2, a screw 3 for adjusting the height of the pressing block, a slider 4, a scale 5, a pressure adjusting block 6, and a positioning screw pin 7.

[0015] Side structure such as image 3 As shown in , the slider 4 locks the pressure regulating block 6 through two adjustment screws 3 . The fixture base is a large horizontal plate to ensure that the module to be tested can be placed horizontally. On the horizontal base, screw holes are processed according to the positioning holes of the module to install the positioning screw pins. The screw pins are detachable to facili...

Abstract

The invention provides an adjustable tool for limiting height. The tool comprises a base. The base is provided with four pillars, a plurality of positioning screw pins, two guide pillars fixed by the pillars at two sides of the top part of the base and a sliding block supported by the two guide pillars. According to the tool of the invention, the positioning screw pins on the base are utilized to have a to-be-measured component fixedly arranged on the base and the sliding block on the sliding guide pillars limits the height of the component. The simply-structured commonly-used tool for limiting height reduces the manufacturing cost of the tools for components with different heights.

Description

technical field [0001] The invention relates to the application field of switching power supply circuit boards, in particular to an adjustable height-limiting jig. Background technique [0002] In recent years, with the rapid development of the power electronics industry, people have paid more and more attention to production efficiency, and inspection standardization has gradually occupied a dominant position in design control, among which high module standardization is a key link in quality control. If there are hand-soldered components in the module, human error causes the components to float high, which may cause the module to work abnormally or even damage other components of the customer, which will inevitably cause huge losses in manpower and cost. [0003] Usually, in circuit board design, ideally, the design ensures that components should not float high, but in actual operation, due to human operation or processing errors, components may float high. In order to che...
