[0030] Reference Figures 1-5,

[0031] A tension testing device for a balance bar 1 is disclosed. The balance bar 1 has a bushing 11 at its end. The testing device is mounted on a fixed platform 4 and includes a test module 21, a fixed module 3, and a drive module 22 connected to the test module 21, all mounted on the fixed platform 4. Both the test module 21 and the fixed module 3 are block structures made of stainless steel. The drive module 22 is a hydraulic cylinder or a pneumatic cylinder; in this embodiment, a pneumatic cylinder is preferred. The test module 21 forms a first abutting portion 2121 that abuts against the bushing 11, and the fixed module 3 forms a second abutting portion 321 that abuts against the bushing 11. The first abutting portion 2121 and the test module 21 are integrally formed, and the second abutting portion 321 and the fixed module 3 are integrally formed. The drive module 22 moves the test module 21 along a preset direction to move the first abutting portion 2121 and the second abutting portion 321 away from each other. When the first abutment portion 2121 and the second abutment portion 321 move away from each other, the balance bar 1 is subjected to tension along the preset direction. A bushing 11 at one end of the balance bar 1 is placed on the test module 21 and abuts against the first abutment portion 2121. A bushing 11 at the other end of the balance bar 1 is placed on the fixing module 3 and abuts against the second abutment portion 321. The drive module 22 moves the test module 21 along a preset direction to perform a tension test on the balance bar 1. If the balance bar 1 is not broken, it proves that the balance bar 1 has passed the tension test. If the connection between the balance bar 1's body 12 and the bushing 11 is broken, it proves that the balance bar 1 has failed the tension test. The preset direction matches the extension direction of the balance bar 1.

[0032] Specifically, the fixed platform 4 is provided with a guide 41 for moving the test module 21 along a preset direction. The guide 41 is a guide rail disposed within the fixed platform 4, and one end of the guide 41 penetrates through the fixed platform 4. During installation, the test module 21 can be directly installed on the fixed platform 4 via the guide 41, and then the fixed platform 4 is fixed to the test bench, making the operation simple. The extension direction of the guide 41 is consistent with the preset movement direction of the test module 21.

[0033] Specifically, the driving module 22 is connected with the mounting portion 211 formed on the test module 21 through a connecting piece 5, the driving module 22 can drive the test module 21 to move from the first position to the second position. The connecting piece 5 is a nut, and the mounting portion 211 is an integral structure with the test module 21. The mounting portion 211 is formed with a through hole matching the diameter of the output end 221, and the output end 221 is formed with a thread. After the output end 221 is inserted into the through hole, the output end 221 is fixed with the mounting portion 211 through the connecting piece 5. Since the connecting piece 5 is fixed with the mounting portion 211 after being installed on the output end 221, the test module 21 can be driven by the driving module 22 to move from the first position to the second position, which is simple in structure and convenient to install. After the connecting piece 5 is removed from the output end 221, the driving module 22 and the test module 21 can be separated, which is convenient to disassemble.

[0034] Specifically, the test module 21 is formed with an embedding groove 212 for placing the bushing 11 and a slot 213 communicating with the embedding groove 212. The embedding groove 212 is formed with a first abutting portion 2121. The slot 213 is used for placing part of the rod body 12 of the balance bar 1. The embedding groove 212 matches the size of the bushing 11, and the bushing 11 abuts against the first abutting portion 2121 after being placed in the embedding groove 212. In this embodiment, the depth of the embedding groove 212 on the test module 21 is greater than the height of the bushing 11. During the tension detection of the balance bar 1, the test module 21 moves towards the driving module 22, thereby applying a tension to the balance bar 1 towards the driving module 22. If the depth of the embedding groove 212 is less than or equal to the height of the bushing 11, the bushing 11 may be ejected from the embedding groove 212 and cause injury to the worker. Therefore, in this embodiment, the depth of the embedding groove 212 is greater than the height of the bushing 11.

[0035] Specifically, the test module 21 is formed with a position gap 214 between the embedding groove 212 and the mounting portion 211. The balance bar 1 tension detection device further comprises a blocking piece 6. The blocking piece 6 is a block structure, and is made of stainless steel. The blocking piece 6 is used for being installed in the position gap 214 and blocking the embedding groove 212 and the slot 213. During the tension detection of the balance bar 1, the connection between the bushing 11 and the rod body 12 of the balance bar 1 is relatively easy to break compared with the rod body 12 of the balance bar 1 and the bushing 11. If the connection between the bushing 11 and the rod body 12 of the balance bar 1 is broken, the bushing 11 may be ejected from the embedding groove 212, thereby causing injury to the worker. Therefore, the blocking piece 6 is arranged in the position gap 214 to avoid injury to the worker. During use, the convex portion formed on the blocking piece 6 is directly inserted into the position gap 214, which is simple to operate.

[0036] Specifically, the fixed module 3 is fixed with the fixed table 4. The fixed module 3 further forms a clamping part 32 and a clamping groove 33 accommodating the rod body 12 on the clamping part 32. The clamping part 32 is integrally formed with the fixed module 3. The bushing 11 can be placed in the groove formed on the fixed module 3, and the edge of the bushing 11 abuts against the clamping part 32, and part of the rod body 12 of the balance bar 1 is located in the clamping groove 33.

[0037] Specifically, the balance bar 1 tension detection device further comprises a protection piece 7. The protection piece 7 is a block structure and is made of stainless steel. The protection piece 7 is installed on the recess 31 and seals the recess 31 and the clamping groove 33. The protection piece 7 avoids the breakage of the connection between the bushing 11 and the rod body 12 of the balance bar 1, and the flying of the bushing 11 from the fixed module 3 to cause harm to the workers. In use, the protection piece 7 only needs to be placed on the fixed module 3, which is simple to operate.

[0038] Specifically, when the test module 21 is at the first position, the distance between the recess 31 and the embedding groove 212 matches the length of the balance bar 1, and at this time, the balance bar 1 can be placed in the detection device for tension detection.

[0039] Specifically, the balance bar 1 tension detection device further comprises a control module 8. The control module 8 is a controller for controlling the driving module 22. The control module 8 is used to control the test module 21 to move from the first position to the second position or to control the control module 8 to move from the second position to the first position.

Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
