[0002] With the development of society, lithium batteries are more and more widely used in life. Therefore, the detection of lithium batteries is becoming more and more strict, and the requirements for lithium battery performance detection fixtures will also be more comprehensive. However, the current lithium battery performance detection fixtures on the market cannot well adapt to the shapes and sizes of various lithium batteries and the clamping is not stable enough. In view of this, we propose a multifunctional lithium battery performance detection fixture. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a multifunctional lithium battery performance detection fixture to solve the problems raised in the related technology.

[0004] To achieve the above purpose, according to one aspect of the utility model, a multifunctional lithium battery performance detection fixture is provided, including a fixture main body and a clamping component. The two fixture main bodies are both fixedly connected with the clamping component. The two clamping components each include a fixed clamping block. A primary power source is fixedly connected to the two fixed clamping blocks. A reciprocating lead screw is arranged at one end of the primary power source. A nut is arranged on the reciprocating lead screw. A moving clamping block is fixedly connected below the nut.

[0005] Further, the clamping component includes a clamping plate. A buckle is fixedly connected to the clamping plate. Slots are opened on the fixed clamping block and the moving clamping block.

[0006] Further, a hinge hinge is fixedly connected to the fixture main body for hingedly connecting the two fixture main bodies to each other.

[0007] Further, springs are hinged to the tails of the two fixture main bodies.

[0008] Further, corrugated grooves are evenly distributed on the clamping surfaces of the fixed clamping block, the moving clamping block and the clamping plate.

[0009] Further, there are four groups of buckles, and their positions respectively correspond to the four groups of slots on the fixed clamping block and the moving clamping block.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] Through the cooperation between the reciprocating screw rod and the nut, the moving clamping block of the present utility model can move. Enlarging the distance between the clamping blocks enables the present utility model to adapt to circular lithium batteries of various sizes. The detachable structure of the clamping plate allows the present utility model to clamp square lithium batteries. The clamping contact surface is provided with a number of grooves to make the clamping more stable, solving the problems that the lithium battery performance detection fixtures on the current market cannot well adapt to the shapes and sizes of various lithium batteries and the clamping is not stable enough.

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in combination with the attached drawings and preferred embodiments, details the specific implementation modes, structures, features and their effects of the present utility model as follows.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A multifunctional lithium battery performance detection fixture, including a fixture main body 1 and a clamping assembly 3. The two fixture main bodies 1 are both fixedly connected with a clamping assembly 3. The two clamping assemblies 3 both include a fixed clamping block 31. A primary power source is fixedly connected to the two fixed clamping blocks 31. One end of the primary power source is provided with a reciprocating screw rod 33. A nut 34 is arranged on the reciprocating screw rod 33. A moving clamping block 35 is fixedly connected below the nut 34 for driving the moving clamping block 35 to move.

[0022] It is worth noting that: the primary power source is preferably a motor 32. The output shaft of the motor 32 is fixedly connected with a reciprocating screw rod 33. The reciprocating screw rod 33 is in threaded connection with the nut 34.

[0023] The clamping assembly 3 includes a clamping plate 36, and a buckle 37 is fixedly connected to the clamping plate 36. Claw chucks 31 and movable clamping blocks 35 are provided with clamping grooves 38 for fixing the clamping plate 36 on the movable clamping block 35.

[0024] It is worth adding that: the clamping plate 36 can be fixed and connected below the movable clamping block 35 by clamping the buckle 37 in the clamping groove 38.

[0025] A hinge hinge 11 is hinged on the fixture body 1 for hingedly connecting two sets of fixture bodies 1 to each other.

[0026] It should be added that the fixture body 1 is composed of two mutually hinged clamping arms, and a hinge hinge 11 is hinged between the two clamping arms for hingedly connecting two sets of fixture bodies 1 to each other.

[0027] Two sets of fixture bodies 1 are fixedly connected with a spring 2 at the tail for clamping the lithium battery tightly.

[0028] It is worth adding that: the upper and lower ends of the spring 2 are fixedly connected to the upper and lower ends of the tail of the fixture body 1.

[0029] The clamping surfaces of the claw chucks 31, the movable clamping blocks 35, and the clamping plates 36 are evenly distributed with corrugated grooves for increasing the friction during the clamping process.

[0030] The overall material of the device is stainless steel to ensure that the overall structure of the device is not damaged when contacting materials such as water, and a layer of insulating rubber is wrapped on the outside of the whole device.

[0031] There are four groups of buckles 37, and the positions respectively correspond to four groups of clamping grooves 38 on the claw chucks 31 and the movable clamping blocks 35.

[0032] The specific principle is as follows: If the lithium battery to be clamped is circular, the clamping plate 36 is removed from the clamping block, and then according to the size of the lithium battery, the motor 32 on the claw chuck 31 rotates to drive the reciprocating lead screw 33 to rotate, so that the nut 34 moves on the reciprocating lead screw 33, and the nut 34 drives the movable clamping block 35 to move to a suitable size for clamping the lithium battery, and then the lithium battery can be clamped between the upper and lower two clamping blocks. Due to the existence of the spring 2 and the hinge hinge 11, the lithium battery will be tightly clamped in the clamping block. If the shape of the lithium battery is square, the clamping plate 36 needs to be fixed on the claw chuck 31 and the movable clamping block 35 by clamping the buckle 37 on the clamping plate 36 into the clamping groove 38, and then the square lithium battery can be clamped.

[0033] The above are only the preferred embodiments of the present utility model, and do not impose any formal limitations on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the technical content disclosed above. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
