[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-4 , a tooling for testing the strength of automotive battery terminals, including a test platform 1, a test base 2 is arranged on the top of the test platform 1, a terminal 3 is placed on the top of the test base 2, a bending arm 4 is sleeved on the surface of the terminal 3 above the test base 2, an insertion rod 5 is inserted through one side of the bending arm 4, and a torque wrench 6 is sleeved on the surface of the insertion rod 5.

[0023] Among them, the test base 2 includes a fixed base 21 placed on the top of the test platform 1, an installation base 22 is fixedly installed on the top of the fixed base 21, and the terminal 3 is inserted into the top of the installation base 22.

[0024] Secondly, the bending arm 4 includes a sleeve 41 sleeved on the surface of the terminal 3 above the test base 2, and a test plate 42 is fixedly installed on the top of the sleeve 41. The lower half of the terminal 3 is placed into the groove on the top of the installation base 22, and the sleeve 41 is sleeved on the upper half of the terminal 3, so that when a bending force is applied to the sleeve 41 through the test plate 42, the terminal 3 is stressed on the vertical center line, increasing the accuracy of the test.

[0025] At the same time, a square hole 421 is opened on one side of the test plate 42, and the insertion rod 5 is inserted into the interior of the square hole 421.

[0026] Among them, a baffle 51 is fixedly installed at one end of the insertion rod 5, and a display screen 61 is fixedly installed on the surface of the torque wrench 6. The test plate 42 is connected to the torque wrench 6 through the insertion rod 5. Rotating the torque wrench 6 drives the insertion rod 5 to rotate, drives the test plate 42 to rotate, drives the sleeve 41 to rotate, and performs a torsion test on the terminal 3.

[0027] Meanwhile, four mounting side plates 7 are fixedly installed on the top of the test platform 1, and the four mounting side plates 7 enclose the test base 2 inside.

[0028] Among them, limit rings 8 are fixedly installed on the inner sides of the four mounting side plates 7. A clamping screw 9 is slidably installed inside the limit ring 8. A limit block 81 is fixedly installed on the inner side wall of the limit ring 8. A card slot 91 adapted to the limit block 81 is formed on the surface of the clamping screw 9. The limit block 81 is stuck inside the card slot 91 on the surface of the clamping screw 9, so that the clamping screw 9 can only move back and forth along the direction of the limit ring 8, and the clamping screw 9 cannot rotate.

[0029] Embodiment 2: On the basis of Embodiment 1, a top plate 10 is fixedly installed at one end of the clamping screw 9 located inside the mounting side plate 7. An internally threaded tube 11 is rotatably installed on the outside of the mounting side plate 7. The clamping screw 9 extends into the internally threaded tube 11 and is threadedly connected to the internally threaded tube 11. A rotating plate 12 is fixedly installed at one end of the internally threaded tube 11. The staff holds a long rod and inserts it into the hole on one side of the rotating plate 12, and uses the lever to rotate the internally threaded tube 11 away, so that the clamping screw 9 drives the top plate 10 to clamp the fixed base 21 on the top of the test platform 1.

[0030] When this embodiment is in use, the test base 2 is placed on the top of the test platform 1. The four top plates 10 move towards the middle to clamp and fix the test base 2 on the top of the test platform 1. Then, the lower half of the terminal 3 is placed into the groove on the top of the mounting base 22, the sleeve 41 is sleeved on the upper half of the terminal 3, and the torque wrench 6 applies torque to the bending arm 4, and the torque value is read through the display screen 61.

[0031] All the electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technologies are not described in the text.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
