Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a metal sheet butt joint jig. Background Art

[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electric control and some other handicrafts. It is mainly used as a tool to assist in controlling position or action. The fixture can be divided into three categories: process assembly fixture, project test fixture and circuit board test fixture. The structure of some electrical components requires multiple stacked metal sheets. The metal sheets before docking are all in a scattered single-piece state because a single metal sheet needs to be docked;

[0003] For example, the Chinese authorized patent with announcement number CN219726050U (a metal sheet docking jig): includes a bottom plate and a docking plate, a receiving groove is provided on the docking plate, a first placement groove is provided on the bottom plate, the docking plate is located in the first placement groove, a through groove is provided at the bottom of the first placement groove, the through groove is connected to the receiving groove, and also includes a lifting part and a baffle, the lifting part includes a lifting plate and an ejector pin, the ejector pin is fixedly connected to the lifting plate, the end of the ejector pin away from the lifting plate passes through the through groove and is located in the receiving groove, the lifting plate is connected with a driving device to drive the lifting part to rise and fall in the receiving groove, the baffle is located at the edge of the bottom plate, and the bottom plate is also connected with an oscillator. The jig in this scheme can oscillate the metal sheet into the receiving groove by oscillating the metal sheet, and complete the docking work of the metal sheet. The jig has low cost, simple operation and high efficiency, and reduces the use of human resources. At the same time, the number of metal sheets in the receiving groove can be adjusted by the lifting part, so that the jig is suitable for more types of metal sheet docking methods and has a wider range of uses.

[0004] However, the existing connection of multiple metal sheets is mostly carried out by using a placement machine, which is large in size and high in cost, resulting in inconvenience in use; therefore, it does not meet the existing needs. In this regard, we propose a metal sheet connection fixture. Utility Model Content
