Description

Technical Field

[0001] The utility model relates to the technical field of copper needle plate detection and positioning, in particular to an adjustable copper needle plate positioning mechanism. Background Art

[0002] As Figure 7 shown, a copper needle plate 3 is an integrated structure composed of a rectangular copper plate 30 and copper needles 31. This kind of copper needle plate is usually applied to the IGBT radiator of new energy vehicles. The copper needle plate is made by cold forging the copper plate. After cold forging, the lengths of the copper needles are different. Subsequently, the pins need to be processed by cutting, grinding, etc. Finally, it is necessary to detect the length and position accuracy of the copper needles. When detecting, it is necessary to position the copper needle plate. Since there are many types of copper needle plates, currently, a dedicated positioning plate is usually designed separately for each type of copper needle plate, that is, a positioning groove adapted to the shape of the rectangular copper plate is provided on the positioning plate for positioning. When detecting copper plates of different models, the positioning plate needs to be repeatedly disassembled and assembled, which is very troublesome to operate. Summary of the Utility Model

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An adjustable copper needle plate positioning mechanism includes a base plate. Four groups of positioning components are arranged on the top surface of the base plate, and the four groups of positioning components are distributed in a cross shape with two opposite groups. Each positioning component includes a fixed seat, a lead screw, and a positioning member. The fixed seat is fixedly connected to the base plate. The lead screw slides through the fixed seat, and the inner end of the lead screw is fixedly connected to the positioning member. The positioning member is slidably connected to the base plate. A driving component is provided on the fixed seat for driving the positioning member to approach or move away from the fixed seat.

[0006] By adopting the above technical scheme, the base plate is installed on the workbench of the detection device. A copper needle plate to be detected is placed on the base plate. The position of the positioning member is adjusted through the driving component, so that the four positioning members are respectively adjusted to abut against the four sides of the copper plate. At this time, the position adjustment of the positioning component is completed. Then, the copper needle plate is taken out. In this way, every time the copper needle plate is loaded, the four sides of the copper needle plate are limited. When the model of the copper needle plate changes, the position of the positioning member is adjusted again according to the above process, so as to be able to adapt to the positioning of various different models of copper needle plates, which is convenient to use and has strong versatility.
