The rotating unit includes a support fixedly connected to one side of the top of the base, a disassembly assembly disposed inside the support, and a clamping assembly disposed on one side of the disassembly assembly. The locking unit includes two movable seats disposed on the other side of the top of the base, a locking assembly disposed inside the movable seats, and a moving assembly disposed at the bottom of the movable seats. This utility model is a clamping device for battery manufacturing. It can rotate a detachable column so that the limiting column fits into the vertical groove, and then pull out the detachable column to replace the new ring. It can also activate two cylinders to drive the telescopic column to descend, thereby driving the lifting plate to descend and limit the top of the battery. It can also change the distance between the two movable seats, improving the applicability of the device.

[0004] Although the device has many advantages, it still has the following problems: The single arc-shaped fixture structure driven by the pneumatic rod has a fixed clamping stroke, which cannot meet the clamping requirements of multiple specifications of workpieces. This results in the need to perform a complete fixture replacement when the production line is switched. Secondly, the mechanical sliding positioning of the slide rail combined with the spring reset mechanism requires manual pushing for position adjustment, which is difficult to meet the requirements of high-precision battery case stamping process.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a clamping device for manufacturing battery casings, including:

[0035] Please see Figures 1-5 This embodiment of a clamping device for manufacturing battery casings includes a base 100, a support plate 120 integrally formed and connected to the top of the base 100, a clamping assembly 200 provided on the side wall of the support plate 120, the clamping assembly 200 including a pressure roller 240 made of rubber, a moving assembly 400 provided inside the base 100, the moving assembly 400 including a mounting plate 450, a fixing assembly 300 provided on the top of the mounting plate 450, the fixing assembly 300 including an upper pressure block 330 and a lower pressure block 320.

[0036] It is worth noting that, in order to facilitate the movement of the fixing component 300, specifically, the top of the base 100 is provided with a sliding groove 110 to facilitate the sliding of the connecting block 440, and the side wall of the support plate 120 is provided with a fixing groove 121.

[0037] Next, in order to clamp the battery casing, specifically, the clamping assembly 200 includes an outer frame 210. The side wall of the outer frame 210 is integrally formed and connected with a fixing member 211, which facilitates the clamping assembly 200 to be fixed on the side wall of the support plate 120. The side wall of the outer frame 210 has a circular groove. Four buffer springs 220 are welded to the inner wall of the circular groove. A mounting base 230 is welded to the top of the buffer spring 220. A rotating shaft is inserted into the top of the mounting base 230. A pressure roller 240 is sleeved on the outer wall of the rotating shaft, which facilitates the clamping and fixing of the battery casing.

[0038] Meanwhile, in order to fix the battery casing in place, the fixing component 300 specifically includes a fixing frame 301. The fixing frame 301 is made of metal and has a hollow structure. A lower spring 310 is welded inside the hollow structure. A lower pressure block 320 is welded to the top of the lower spring 310. A pneumatic rod 350 is inserted into the top of the fixing frame 301. The output end of the pneumatic rod 350 passes through the fixing frame 301 and is welded to an upper spring 340. An upper pressure block 330 is welded to the bottom of the upper spring 340. The upper pressure block 330 is driven to press down by the pneumatic rod 350, which works with the lower pressure block 320 to compress and fix the battery casing.

[0039] Furthermore, to facilitate the movement of the fixed component 300 by the movable component 400, the movable component 400 specifically includes a worm gear 410, a worm wheel 420 meshing with the outer circumference of the worm gear 410, a rotating shaft inserted into the side wall of the worm wheel 420, a mounting base 430 sleeved on the side wall of the rotating shaft, a connecting block 440 welded to the top of the mounting base 430, a mounting plate 450 welded to the top of the connecting block 440, and a magnetic block 451 fixedly connected to the top of the mounting plate 450 by screws. The magnetic block 451 is used to magnetically fix the fixed frame 301.

[0040] It is worth noting that, in order to fix the clamping component 200 to the support plate 120, specifically, the fixing groove 121 has a circular groove inside, which makes it convenient for the fixing member 211 to be inserted into the fixing groove 121 and rotated for fixation. The shape and size of the fixing groove 121 match the shape and size of the fixing member 211, which makes it convenient for the fixing member 211 to be inserted. The bottom of the fixing frame 301 has multiple square grooves, the shape and size of which match the shape and size of the magnetic block 451, which makes it convenient for the fixing frame 301 to be fixedly connected to the mounting plate 450.

[0041] Finally, to facilitate the operation of the movable component 400, specifically, a worm gear 410 is inserted into the base 100, and a handle is sleeved on the side wall of the worm gear 410 through the base 100. By controlling the handle to rotate the worm gear 410, the ease of operation is improved.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of the clamping device for manufacturing battery casing according to this embodiment is as follows:

[0044] 1: Insert the fixing member 211 of the clamping assembly 200 into the fixing groove 121, and then rotate the outer frame 210 to rotate the fixing member 211 until it intersects with the groove opening of the fixing groove 121 to fix the clamping assembly 200. The fixing assembly 300 is then inserted and fixed by the magnetic block 451 protruding from the top of the mounting plate 450 and the square groove at the bottom of the fixing bracket 301.

[0045] 2: Insert the material into the circular groove opened on the side wall of the outer frame 210, and make the side wall of the material fit against the outer circumference of the pressure roller 240. Then, the pressure roller 240 clamps and fixes the material by the elastic thrust of the buffer spring 220. Move the fixing frame 301 to the other end of the material and insert the material into the hollow structure of the fixing frame 301. Then, the upper spring 340 and the upper pressure block 330 are driven to press down vertically by the pneumatic rod 350, and the material is squeezed and fixed by the lower spring 310 and the lower pressure block 320.

[0046] 3: When the position of the fixing component 300 needs to be adjusted, hold the handle and rotate it. Then the handle controls the worm gear 410 to rotate, which in turn drives the worm wheel 420 to make the connecting block 440 move laterally along the slide groove 110, and then the fixing bracket 301 moves laterally.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
