Description

Technical Field

[0001] The utility model belongs to a battery case clamp, and particularly relates to a clamp for battery case processing. Background Art

[0002] During the processing of a battery case, it is necessary to apply glue dots on the surface of the battery case. If the clamp for holding the storage battery cannot fix the case of the storage battery well, situations such as shaking and displacement may occur. When applying sealant glue dots to the battery case, the shaking and displacement of the battery case will cause the glue dots to shift.

[0003] Chinese Patent with the publication number CN220239134U discloses a battery case clamp, which has a clamp body. The clamp body includes a first clamp and a second clamp. The first clamp and the second clamp respectively hold both ends of the battery case. Both the first clamp and the second clamp have a first groove and a second groove with sizes larger than those of the battery case. The clamp body holds and fixes the battery case through the first groove and the second groove.

[0004] However, the above patent has the following deficiencies:

[0005] The above patent holds both ends of the storage battery case by setting the first clamp and the second clamp, and both ends of the storage battery case are received in the first groove and the second groove, which improves the stability of clamping and fixing. By setting the sizes of the first groove and the second groove to be larger than those of the storage battery case, it is convenient to load and unload the clamp. However, in the above patent, the sizes of the first groove and the second groove are not adjustable. As a result, if the sizes of the first groove and the second groove are set to be much larger than those of the storage battery case, the battery case will still shift after being clamped. If the sizes of the first groove and the second groove are set to be slightly larger than those of the storage battery case, it is still not convenient enough to hold and take out the battery case. Content of the Utility Model

[0006] The utility model provides a clamp for battery case processing, aiming at solving the problem in the above background art that the sizes of the first groove and the second groove in the above patent are not adjustable. As a result, if the sizes of the first groove and the second groove are set to be much larger than those of the storage battery case, the battery case will still shift after being clamped. If the sizes of the first groove and the second groove are set to be slightly larger than those of the storage battery case, it is still not convenient enough to hold and take out the battery case.

[0007] The present utility model is realized as follows. A fixture for processing a battery housing includes a base. The base is provided with anti-slip pads, which are made of rubber material, and the number of the anti-slip pads is set to be multiple. Above the top of the base, there is a fixed frame. One side of the fixed frame is provided with a positioning mechanism, which is used to limit the outer periphery of the battery housing, thereby improving the fixing accuracy of the battery housing. The number of the positioning mechanisms is set to be two;

[0008] Inside the fixed frame, there is a clamping mechanism, which is used to adjust the distance between the two positioning mechanisms, thereby fixing the battery housing;

[0009] Between the base and the fixed frame, there is a lifting mechanism, which is used to adjust the height of the fixed frame.

[0010] Preferably, the positioning mechanism includes an installation box and a limiting frame. A first stepping motor is fixedly connected to the side wall of the installation box. A sliding groove is opened on the outer periphery of the installation box, and the number of the sliding grooves is set to be four. Inside each of the four sliding grooves, a telescopic rod is slidably arranged. Grooves are opened on the side walls of the four telescopic rods, and driven racks are fixedly connected to the inner walls of the four grooves;

[0011] Inside the installation box, there is a rotating rod. One end of the rotating rod is rotatably connected to the inner wall of the installation box, and the other end of the rotating rod is fixedly connected to the output shaft of the first stepping motor. Driving gears are fixedly connected to the outer periphery of the rotating rod. The number of the driving gears is set to be four, and the four driving gears are coaxially distributed. The four driving gears are respectively meshed and connected with the four driven racks;

[0012] The limiting frame is composed of four positioning rods. Baffles are fixedly connected to the side walls of the four positioning rods, and the four positioning rods are respectively fixedly connected to the four telescopic rods;

[0013] By starting the first stepping motor to rotate clockwise, the rotating rod and the four driving gears can be driven to rotate synchronously. At the same time, the four driving gears will respectively drive the four meshed racks and the telescopic rods to slide away from the installation box in the sliding grooves. At the same time, the four telescopic rods will respectively drive the four positioning rods to move away from the installation box. At this time, the side wall of the installation box is abutted against the side wall of the battery housing, and the two first stepping motors are driven to rotate in the reverse direction. Through the above structure, the four positioning rods can be driven to move towards the installation box until the four positioning rods are combined into a limiting frame to limit and fix one side of the battery housing. The two positioning mechanisms are used to fix the two sides of the battery housing, thereby improving the fixing accuracy of the battery housing. When it is necessary to release the fixation of the battery housing, by starting the two first stepping motors to rotate clockwise, the two groups of positioning rods can be moved away from the installation box, thereby facilitating the disassembly of the battery housing.

[0014] Preferably, the clamping mechanism includes a second stepping motor and a bidirectional threaded rod, and the side wall of the second stepping motor is fixedly connected to the side wall of the limiting frame;

[0015] The bidirectional threaded rod is arranged on the inner wall of the fixed frame. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the fixed frame, and the other end of the bidirectional threaded rod is fixedly connected to the output shaft of the second stepping motor. Two driving blocks are threadedly connected to the outer periphery of the bidirectional threaded rod. Both driving blocks are slidably connected to the fixed frame. Connecting rods are fixedly connected to the side walls of both driving blocks, and connecting frames are fixedly connected to the ends of both connecting rods. The two connecting frames are respectively fixedly connected to the two mounting boxes;

[0016] By starting the second stepping motor, the bidirectional threaded rod can be driven to rotate, and the two driving blocks threadedly connected to the bidirectional threaded rod are limited by the fixed frame and cannot rotate on their own. Therefore, by controlling the rotation direction of the second stepping motor, the two driving blocks can be controlled to move towards or away from each other. At the same time, the two driving blocks will respectively drive the mounting box to move through the two connecting rods and connecting frames, thereby adjusting the distance between the two positioning mechanisms, so that the positioning mechanisms can be clamped on both sides of the battery case.

[0017] Preferably, the lifting mechanism includes a fixed sleeve rod, a lifting rod is slidably arranged at the top of the fixed sleeve rod, one end of the lifting rod away from the fixed sleeve rod is fixedly connected to the fixed frame, and a fixing bolt is threadedly connected to the side wall of the fixed sleeve rod, and the end of the fixing bolt abuts against the lifting rod;

[0018] By adjusting the height of the lifting rod, the height of the fixed frame can be adjusted, so that the height of the clamped battery case can be adjusted, so that the battery case can match processing devices of different heights. Finally, by rotating the fixing bolt, the end of the fixing bolt abuts against the lifting rod, so that the lifting rod can be fixed by friction.

[0019] Preferably, reinforcing rods are arranged on both sides of the fixed sleeve rod. The reinforcing rods are inclined. One end of the reinforcing rod is fixedly connected to the base, and the other end of the reinforcing rod is fixedly connected to the fixed sleeve rod;

[0047] The working principle and usage process of the present utility model:

[0048] By starting the first stepping motor 23 to rotate clockwise, the rotating rod 28 and the four driving gears 29 can be driven to rotate synchronously. At the same time, the four driving gears 29 will respectively drive the four meshed racks and the telescopic rods 25 to slide away from the installation box 21 in the chute 24.

The two positioning mechanisms 2 are used to fix the two sides of the battery housing, so as to improve the fixing accuracy of the battery housing;

[0051] When it is necessary to release the fixation of the battery housing, by starting the two first stepping motors 23 to rotate clockwise, the two groups of positioning rods 210 can be moved away from the mounting box 21, so as to facilitate the disassembly of the battery housing;

[0052] By adjusting the height of the lifting rod 42, the height of the fixed frame 12 can be adjusted, so that the height of the clamped battery housing can be adjusted, so that the battery housing can be matched with processing devices of different heights.
