Description

Technical Field

[0001] This utility model relates to the field of clamp tension adjustment technology, and in particular to a clamp tension adjustment device for a testing device. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for operation or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. Fixture testing mainly involves testing and experimenting on the function, principle, lifespan, and performance of a product.

[0003] Existing tensile testing machines use upper and lower clamps to hold the test object during testing to measure the clamping force. Start-up via a control console causes the ball screw inside the lifting device to drive a moving beam with the upper clamp via a motor. The clamping tightness can be adjusted according to the height reached. However, with prolonged operation, the ball screw rotates continuously, and the sliding block rubs against it, causing dust and wear to accumulate on its surface. This can lead to the sliding block getting stuck along the ball screw surface, affecting the accuracy of the lifting height test data and impacting work efficiency.

[0004] To address this issue, we propose a clamping tension adjustment device for the testing apparatus. Utility Model Content

A rectangular block is fixedly installed on the front surface of the 4 to effectively fix the moving crossbeam 3. A fixed crossbeam 4 is installed between the lifting devices 2 to support the oil tank 41 and prevent lubricating oil from overflowing during operation. An oil tank 41 is fixedly installed on the upper end of the fixed crossbeam 4 to facilitate the storage of lubricating oil and prevent insufficient lubricating oil from affecting work efficiency. Conveying pipes 42 are sleeved on both sides of the oil tank 41 to facilitate effective conveying and prevent lubricating oil from overflowing and affecting the working environment. One end of the conveying pipe 42 is connected to the outlet of the water pump 43 for effective control and to prevent waste.

[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the bottom of the lifting device 2 is provided with a slot, and the ball screw 23 passes through the lifting device 2 and connects to the drive motor inside the base 1, so as to facilitate effective control by the control console. The surface of the lifting device 2 is provided with a groove, and a cover plate 21 is fixedly installed inside the groove. The cover plate 21 is connected and fixed by a three-in-one connecting rod. The surface of the cover plate 21 is provided with a through groove that matches the rectangular block, so as to facilitate the vertical sliding of the rectangular block at the front end of the sliding block 24.

[0025] Furthermore, refer to Figure 2 and Figure 3It can be seen that a sliding block 24 is sleeved at the center of the ball screw 23, which facilitates the movement of the sliding block 24 by rotating the ball screw 23. A rectangular block is fixedly installed on the front surface of the sliding block 24, which facilitates the fixed support of the moving crossbeam 3 and the testing of the clamping force of the upper and lower clamps. Lubricating blocks 25 are connected to the upper and lower sides of the sliding block 24, and cotton strips 26 are installed and connected inside the hole, which facilitates the even application of lubricating oil to the surface of the ball screw 23 according to the sprayed lubricating oil, and prevents rust and jamming.

[0026] Furthermore, refer to Figure 4 It can be seen that the upper surface of the oil tank 41 is provided with a feed port, which facilitates timely and effective replenishment of lubricating oil and convenient and effective extraction of lubricating oil, preventing the oil from being unable to be extracted due to sealing issues.
