Description

Technical Field

[0001] The utility model relates to the technical field related to power battery clamping, and in particular to a clamping mechanism for power battery assembly. Background Art

[0002] The power battery module is generally composed of multiple power batteries arranged together. A clamping mechanism is required when assembling the power battery. The existing clamping mechanism for clamping a row of power batteries is a hand-cranked screw clamping mechanism. The handwheel is manually driven to rotate the screw, and the two clamping blocks are linked to each other to achieve clamping. The clamping speed is relatively slow, which affects the assembly efficiency of the power battery module. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a clamping mechanism for power battery assembly to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a clamping mechanism for power battery assembly is designed, comprising:

[0006] The base has two bakelite strips built into the top horizontally;

[0007] A first mounting seat is laterally adjustable and fixedly connected to the left end of the base, and a first clamping block is fixedly connected to the right end of the first mounting seat;

[0008] The second mounting seat is arranged at the right end of the base and is laterally slidably cooperated with the base through a guide assembly. A second clamping block is provided at the left end of the second mounting seat. The second clamping block corresponds to the first clamping block on the left and right. A clamping locking unit is fixedly connected to the bottom of the second mounting seat. When the clamping locking unit is activated, it can clamp the guide assembly to lock the movement of the second mounting seat.

[0009] By adopting the above technical solution, when the power batteries need to be clamped and assembled, a row of power batteries are placed between the first clamping block and the second clamping block of the clamping mechanism, and the two bakelite strips support the power batteries. Then, the second mounting seat is driven to move left and abut against the power batteries manually or by a robot or other driving unit. Then, the clamping locking unit starts the clamping guide assembly, thereby locking the movement of the second mounting seat to achieve long-term clamping of the power batteries. Compared with the existing hand-cranked screw clamping mechanism for clamping power batteries, it can achieve rapid clamping of power batteries and improve the assembly efficiency of power batteries.

[0010] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0011] In some embodiments, the guiding assembly includes a guide rail and a slider. The two guide rails are horizontally fixed on the base, and the two sets of sliders are fixed to the bottom of the second mounting seat and are horizontally slidably engaged with the two guide rails correspondingly. The clamping and locking unit is fixed to the bottom left end of the second mounting seat. When the clamping and locking unit is activated, it can clamp the guide rail to lock the movement of the second mounting seat.

[0012] In some embodiments, the first mounting seat is connected to the base by screws, and a number of threaded holes for adjusting the fixed position of the first mounting seat are horizontally spaced on the base.

[0013] In some embodiments, the second mounting seat includes a bottom plate, an E-shaped seat and a U-shaped seat fixed to the bottom plate. A limiting assembly for restricting the movement of the second mounting seat is installed on the U-shaped seat. When the clamping mechanism is in a non-clamping state, the clamping and locking unit is not activated. In order to prevent the second mounting seat from moving left and right, the limiting assembly is provided to restrict the movement of the second mounting seat.

[0014] In some embodiments, the limiting assembly includes a slide bar, a connecting rod, a spring, a T-shaped part and a limiting hole. The two slide bars are vertically slidably engaged with the U-shaped seat. The two ends of the connecting rod are correspondingly connected to the two slide bars. The lower ends of the two slide bars are connected to the T-shaped part. The spring is sleeved on the slide bar, and the upper end of the spring abuts against the U-shaped seat and the lower end abuts against the T-shaped part. The lower end of the T-shaped part is vertically slidably engaged with the through hole on the bottom plate. The limiting hole is provided on the base, and the lower end of the T-shaped part can be inserted into the limiting hole.

[0015] In some embodiments, a plurality of bearings are sleeved on the connecting rod.

[0016] In some embodiments, the clamping and locking unit is a pneumatic clamp.

[0017] In some embodiments, the clamping and locking unit is a hydraulic clamp.

[0018] In some embodiments, a limiting block is fixed to the right end of the base, and a stop bolt is fixed to the limiting block. The stop bolt corresponds to the bottom plate on the second mounting seat left and right. Thus, the rightward movement position of the second mounting seat can be restricted.

[0028] Two electric wooden strips 11 are horizontally fixed on the top of the base 1, and the electric wooden strips 11 are used to support the power battery.

[0029] The first mounting base 2 is horizontally adjustably fixed to the left end of the base 1. Specifically, the first mounting base 2 is connected to the base 1 by screws. A number of threaded holes 12 for adjusting the fixed position of the first mounting base 2 are horizontally spaced on the base 1. The threaded end of the screw passes through the through hole on the first mounting base 2 and is connected to the threaded hole 12 to fix the first mounting base 2. A first clamping block 20 is fixed to the right end of the first mounting base 2. The first clamping block 20 has one or two or three. In this embodiment, it is preferably that the first clamping block 20 has three.

[0030] The second mounting base 3 is arranged at the right end of the base 1 and is horizontally slidably matched with the base 1 through a guiding component 4. The guiding component 4 includes a guide rail 41 and a slider 42. Two guide rails 41 are horizontally fixed to the base 1. There are two groups of sliders 42. Each group of sliders 42 has two.
