Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, and in particular to a stamping and forming clamping mechanism for sheet metal parts of a power exchange cabinet. Background Art

[0002] A battery swap cabinet is a device used to store and charge batteries. It usually has an appearance structure similar to a locker. It consists of multiple compartments, each of which can store a battery. It is also equipped with a charging device that can automatically charge the battery. Users can easily rent and return batteries by operating through the display screen or scanning a QR code. Battery swap cabinets are mostly made of sheet metal, which is a comprehensive cold processing process for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, and forming.

[0003] In the prior art, sheet metal stamping and forming refers to a processing and forming method in which a press and a mold apply external force to plates, strips, tubes, and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Existing stamping and forming equipment requires a clamping mechanism to clamp and position the sheet metal parts during processing. However, common clamping mechanisms can only simply clamp and fix the two sides of the sheet metal parts when positioning them, and the clamping strength is low. If the upper surface needs to be clamped at the same time, different clamping mechanisms need to be re-operated to fix it, and the operation method is relatively cumbersome. How to invent a clamping mechanism for stamping and forming sheet metal parts of a power exchange cabinet to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a stamping and forming clamping mechanism for sheet metal parts of a power exchange cabinet, aiming to improve the problem that common clamping mechanisms need to be re-operated with different clamping mechanisms for fixation, and the operation method is relatively cumbersome.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a punching and forming clamping mechanism for sheet metal parts of a power exchange cabinet, comprising a fixed platform, an adjustment block and a fixed plate arranged on the fixed platform, one end of the fixed platform is fixedly connected to a side plate, an adjustment groove is opened on the upper surface of the fixed platform, a double-headed screw is installed on the inner wall of the adjustment groove, and a motor is installed at one end of the fixed platform;

[0007] The lower end of the adjusting block is fixedly connected to a driving block which is slidably connected to the inner wall of the adjusting groove;

[0008] The lower end of the fixed plate is fixedly connected to a slider slidably connected to the inner wall of the adjustment groove, one end of the slider is provided with a mounting groove, the inner wall of the mounting groove is provided with a first spring fixedly connected to one end of the driving block, one end of the fixed plate is provided with a side clamping plate, the upper outer wall of the fixed plate is provided with a limiting rod, the outer side of the limiting rod is provided with a second spring, and one end of the second spring is provided with an upper clamping plate.

[0009] Preferably, both ends of the double-headed screw are rotatably connected to the inner wall of the adjusting groove, and the output end of the motor is fixedly connected to one end of the double-headed screw.

[0010] Preferably, the two adjusting blocks are symmetrically mounted at both ends of the adjusting groove, and the inner wall of the driving block and the outer wall of the double-headed screw are threadedly connected.

[0011] By adopting the above technical solution, the sheet metal to be stamped is placed on the fixed table, and one end of the side wall is pressed against the side plate. Then the motor is started to rotate the double-headed screw, thereby driving the adjustment blocks on both sides of the fixed table to approach each other and complete the clamping and fixing of the sheet metal through the side clamping plate.

[0012] Preferably, the inner wall of the slider is slidably connected to the outer wall of the double-headed screw, the first spring is sleeved on the outside of the double-headed screw, and the side wall of one end of the first spring is fixedly connected to the inner wall of the mounting groove.

[0013] Preferably, the side walls at both ends of the second spring are fixedly connected to the outer walls of the fixing plate and the upper clamping plate respectively, the outer wall of the limit rod is slidably connected to the inner wall of the upper clamping plate, and one side of the side clamping plate and the upper clamping plate are fixedly connected with multiple anti-slip strips.

[0014] Preferably, one end of the upper clamping plate is fixedly connected to an inclined block having the same angle as the inclined groove, and the inner wall of the inclined block is rollingly connected to a plurality of balls rollingly connected to the outer wall of the inclined groove.

[0015] By adopting the above technical solution, when the side clamping plate completes clamping the sheet metal part, the motor continues to work to make the adjustment block continue to slide, so that the outer wall of the inclined groove squeezes the inclined block, and then the inclined block drives the upper clamping block to slide down through the ball bearing to clamp the upper surface of the sheet metal part.

[0016] The beneficial effects of the utility model are:

[0017] The sheet metal to be stamped is placed on the fixed table, and the side wall of one end of it is against the side plate. Then the motor is started to rotate the double-headed screw, thereby driving the adjusting blocks on both sides of the fixed table to approach each other. At the same time, the first spring connected to the driving block drives the side clamping plate at one end to approach each other to clamp and fix the side wall of the sheet metal. The motor continues to work to make the adjusting block squeeze the first spring to continue sliding. At the same time, the inclined groove on one side of the adjusting block squeezes the inclined block at one end of the upper clamping plate. At this time, the ball on the inclined block and the outer wall of the inclined groove roll, forcing the upper clamping plate to squeeze the second spring and move downward to clamp and fix the upper surface of the sheet metal below, thereby directly clamping and fixing multiple positions of the sheet metal, improving the clamping effect and facilitating operation.
