Description

Technical Field

[0001] The utility model belongs to the technical field of power batteries, and in particular relates to a universal battery shell clamping device. Background Art

[0002] In the battery manufacturing process, it is often necessary to use a clamp to clamp and position the battery shell, and then assemble the battery. For example, in the battery shell assembly process, the battery shell needs to be placed in the clamp for positioning and clamping, and then transferred to the next station to load the battery; after the assembly is completed, the clamping assembly releases the battery. The existing clamp has excessive clamping force, which is easy to clamp the shell and cause poor appearance. A Chinese patent discloses a clamping device for top welding of metal shell batteries, application number: 201410816186.8, which includes a fixed plate, a clamping claw retracting mechanism for clamping the metal top cover, a long side positioning mechanism for clamping the long side of the metal shell, and a short side positioning mechanism for clamping the short side of the metal shell. The clamping claw retracting mechanism, the long side positioning mechanism and the short side positioning mechanism are all fixed on the fixed plate. The clamping claw retracting mechanism includes a clamping claw, a transmission mechanism, a first power device and a slide groove. The output end of the first power device is connected to the slide groove, and the slide groove is connected to the clamping claw through a first screw. The structure is too complicated and inconvenient for workers to operate. Utility Model Content

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0015] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0016] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figure 1 and Figure 2 As shown, a universal battery shell clamping device includes a base 1, a guide rail 2, a moving block 3, a spring 4, a connecting arm 5, a clamping block 6 and a positioning block 7; the guide rail is fixed on the base, the bottom of the moving block is slidably connected to the guide rail, the moving block slides left and right on the guide rail, one end of the moving block is connected to the spring mounting block 14 through the spring, the spring mounting block is fixed on the base, the spring gives a clamping force to the moving block, so that the moving block always moves toward the positioning block, and then clamps the battery shell, the connecting arm is fixed on the upper part of the moving block, the front end of the connecting arm is hinged with a clamping block, the positioning block is fixed to one side of the base and corresponds to the clamping block. The battery shell is placed between the positioning block and the clamping block to clamp the battery shell.

[0018] As a further improvement of the utility model, the front end of the clamping block is provided with two rubber clamping wheels 8. The rubber clamping wheels can be adjusted automatically according to the surface of the battery shell, which can avoid scratching the battery shell on the one hand and clamp the battery shell more firmly on the other hand.

[0019] In order to position the moving block, a positioning groove is provided on the side of the moving block, a positioning plate 9 is fixed on the base, a positioning pin 10 is inserted on the positioning plate, and the positioning pin cooperates with the positioning groove. The end of the positioning pin is in the shape of a needle tip, and the positioning pin passes through the positioning plate and can be inserted into the positioning groove of the moving block to position the moving block.
