Description

Technical Field

[0001] This utility model specifically relates to a nut force application device based on lithium battery testing. Background Technology

[0002] During the process of mounting the battery on the clamp, it is usually necessary to apply force to the nuts one by one with a torque wrench. Applying force individually will change the initial force on the nuts, and may even cause them to loosen. Repeated application of force is required to correct this, which affects work efficiency. It is also time-consuming and labor-intensive when dealing with clamps with many bolts. After some batteries have been tested, they expand and the battery clamps are difficult to disassemble manually. To address this, we propose a nut-applying device based on lithium battery testing. Utility Model Content

[0003] The purpose of this invention is to provide a nut-applying force device based on lithium battery testing to solve the problems mentioned in the background art.

[0008] The battery is located in the middle of the inner side of the housing, and the battery is electrically connected to the drive assembly via wires.

[0009] The battery drives the drive assembly, which in turn rotates multiple adjusting sleeves, making it easier to tighten multiple nuts and reducing the inconvenience of manual operation one by one.

[0010] Preferably, the drive assembly includes a motor module, a first adjusting rod, an adjusting groove, and a locking block structure. Multiple motor modules arranged in an array are disposed inside the housing. The first adjusting rod is slidably connected to the inner side of the motor module in the transverse direction, and the second adjusting rod is vertically offset from the first adjusting rod on the inner side of the motor module in the longitudinal direction. Both the first and second adjusting rods have locking block structures at their ends. The inner edge of the housing is provided with an adjusting groove that cooperates with the locking block structure.

[0011] This allows for easy movement and adjustment of the motor module, thereby changing the position of the adjusting sleeve to accommodate the position of the nut on different clamps.

[0012] Preferably, the locking block structure includes a locking plate and a limiting block. The locking plate is slidably sleeved on one end of the first adjusting rod, and a slider that cooperates with the adjusting groove is provided on one side wall of the locking plate. A spring button is fixed on one end of the slider, and a spring is provided between the spring button and the first adjusting rod. The limiting block is fixed on one side of the housing, and the limiting block cooperates with a locking groove opened on one side of the locking plate.

[0013] This allows for quick locking or unlocking of the ends of the first or second adjusting rod, thereby enabling the motor module to move and adjust via the first and second adjusting rods.

[0014] Preferably, the upper surface of the limiting block is serrated.

[0015] This allows for the restriction of block displacement via a serrated pattern after adjustment.

[0016] Preferably, the adjusting groove is rectangular, and the number of adjusting grooves is the same as the number of clamping plates.

[0017] Preferably, the handle is U-shaped.

[0035] Battery 8 is located in the middle of the inner side of housing 1, and battery 8 is electrically connected to drive assembly through wires;

[0036] This facilitates the supply of electrical power to the drive components, enabling multiple adjusting sleeves 6 to rotate simultaneously, thereby allowing the selection of nuts to apply force.

[0037] In this embodiment, preferably, the drive assembly includes a motor module 9, a first adjusting rod 10, an adjusting groove 12, and a locking block structure. Multiple motor modules 9 arranged in an array are disposed inside the housing 1.

The ends of the first adjusting rod 10 and the second adjusting rod 13 are both equipped with locking block structures. The inner edge of the housing 1 is provided with an adjusting groove 12 that cooperates with the locking block structure.

[0038] This allows for easy movement and adjustment of the position of the motor module 9 in the horizontal or vertical direction, thereby moving the adjusting sleeve 6 on the lower surface of the motor module 9 so that the adjusting sleeve 6 corresponds to the nuts at different positions and is connected to the nuts. The preferred motor model used in the motor module 9 is 12GFN20.

[0039] In this embodiment, preferably, the card block structure includes a card plate 11 and a limiting block 15.
