Description

Technical Field

[0001] The utility model relates to the technical field of hardware clamps, in particular to an adjustable clamp for hardware testing. Background Art

[0002] Hardware test fixtures are special fixtures used to test and inspect hardware products. Hardware products include various hardware parts, hardware tools and hardware accessories. Hardware test fixtures can be used to test the size, shape, hardness, strength, density, electrical performance and other indicators of hardware products to evaluate the quality and reliability of the products.

[0003] Some existing hardware testing fixtures are composed of two adjusting parts and a clamping plate. When using them, the staff first needs to rotate the adjusting part so that the adjusting part pushes the clamping plate to clamp the hardware parts. This method requires the staff to manually rotate the adjusting part to adjust and clamp it. Since the staff needs to manually rotate the adjusting part to adjust the clamping force and position, this requires a certain amount of strength and labor, especially when frequent clamping adjustments are required, which will increase the labor intensity of the staff. In addition, it takes a certain amount of time to manually rotate the adjusting part for clamping adjustments, especially when multiple hardware parts need to be adjusted, which will increase the time consumption of the testing process and reduce production efficiency.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 - Figure 3As shown, the utility model provides a technical solution: an adjustable clamp for hardware testing, comprising: a clamping mechanism 1, the clamping mechanism 1 comprises a workbench 11, a fixing mechanism 2 is arranged at the bottom of the workbench 11, a motor 12 is arranged on one side of the workbench 11, a first threaded rod 13 is arranged at one end of the output shaft of the motor 12, a first gear 14 is arranged on the surface of the other end of the first threaded rod 13, a second gear 15 is arranged on the surface of the first gear 14, a second threaded rod 16 is arranged on the inner wall of the second gear 15, nuts 17 are arranged on the surfaces of the first threaded rod 13 and the second threaded rod 16, connecting frames 18 are arranged on the surfaces of the two nuts 17, clamp rings 19 are arranged on one side of the top of the two connecting frames 18, and sliders 110 are arranged on the surfaces of the two clamp rings 19.

[0027] In this embodiment, the surface of the motor 12 is fixedly connected to one side of the workbench 11, and one end of the output shaft of the motor 12 is fixedly connected to the slot provided on the same side of the workbench 11 and one end of the first threaded rod 13; the above components are matched, and when the staff uses it, they can first start the power, and when the motor 12 starts, it will drive the first threaded rod 13 to rotate; the driving method of the motor 12 can reduce the physical burden of the staff, especially when the clamp is operated for a long time or frequently. The staff only needs to start the motor 12, and there is no need to forcefully rotate the threaded rod, thereby reducing labor intensity and improving work comfort;

[0028] The other end surface of the first threaded rod 13 is fixedly connected to the inner wall of the second gear 15, the teeth of the first gear 14 are meshed with the second teeth, the inner wall of the second gear 15 is fixedly connected to the surface of one end of the second threaded rod 16, and the other end of the second threaded rod 16 is rotatably connected to the slot provided on the inner wall of the workbench 11. The above components cooperate with each other, and when the first threaded rod 13 rotates, it will synchronously drive the first gear 14 to rotate, and when the first gear 14 rotates, its teeth will mesh with the tooth grooves of the second gear 15, thereby driving the second gear 15 to rotate synchronously, and when the second gear 15 rotates, it will synchronously drive the second threaded rod 16 to rotate. This method realizes its synchronous rotation, and through the meshing of the teeth of the gears, it can achieve higher synchronization and rotation accuracy. When the first threaded rod 13 rotates, the gear transmits the torque, so that the second threaded rod 16 rotates at the same speed, direction and angle, ensuring that the fixture clamps the workpiece symmetrically on both sides to prevent deviation or unevenness. Through gear transmission, the power can be effectively transmitted to the second threaded rod 16. Gear transmission has high transmission efficiency, can reduce energy loss, and improve the efficiency and effect of power transmission;

[0029] The surfaces of the first threaded rod 13 and the second threaded rod 16 are both threadedly connected with nuts 17, and the surfaces of the two nuts 17 are fixedly connected with connecting frames 18, and the two connecting frames 18 are slidably connected with the slots opened on one side of the workbench 11, and the tops of the two connecting frames 18 are fixedly connected with clamping rings 19, and the surfaces of the two clamping rings 19 are fixedly connected with sliders 110, and the bottoms of the two sliders 110 are slidably connected with the sliding grooves opened on the workbench 11. The above components cooperate with each other, and when the first threaded rod 13 and the second threaded rod 16 rotate, the two corresponding nuts 1 7 will also cooperate with the threads opened on the inner wall and the threads opened on its surface to achieve the synchronous adjustment position of the two nuts 17. When the nut 17 moves, it will synchronously drive the connecting frame 18 and the clamping ring 19 to adjust. The slider 110 can be more stable when the clamping ring 19 is adjusted to avoid displacement when it is hit. The staff only needs to start the motor 12 to adjust the position of the clamping ring 19, so as to control its clamping of hardware parts of different sizes and the clamping force. By adjusting the position of the nut 17, not only the adjustment of the connecting frame 18 and the clamping ring 19 can be achieved. In this way, the size of the clamping hardware parts can be flexibly controlled to meet the size requirements of different workpieces. The clamping force can also be adjusted to ensure the stability and safety of the clamping parts. Only by starting the motor 12, the position of the clamping ring 19 can be adjusted by the movement of the nut 17. Compared with manual adjustment or other complicated operation methods, this method is simpler and more efficient, reducing the difficulty and time cost of the staff. At the same time, through the drive of the motor 12, the moving speed of the nut 17 can be controlled more accurately and stably. This can improve the efficiency of adjustment, reduce adjustment time, and also improve the stability and reliability of clamping the workpiece.

[0030] Example 2

[0031] like Figure 1 - Figure 4 As shown, the fixing mechanism 2 includes a support plate 21, two support plates 21 are fixedly connected to the bottom of the workbench 11, the inner walls of the slots opened on one side of the multiple support plates 21 are fixedly connected to the mounting plates 22, and the inner walls of the slots opened on the multiple mounting plates 22 are threadedly connected to the fixing parts 23.

[0032] In this embodiment, by cooperating with the above components, a more stable structure can be formed by combining two more support plates 21 and mounting plates 22. The workbench 11 will not shake or sway during use, ensuring the accuracy and stability of the work. The staff can also fix the mounting plate 22 to the ground through the fixing member 23, so that the whole is more stable during use and avoids displacement or tilting due to collision.

[0033] Working principle:

[0034] like Figure 1 - Figure 4As shown, when the staff uses it, they can first start the electric motor 12. When the motor 12 is started, it will drive the first threaded rod 13 to rotate. When the first threaded rod 13 rotates, it will synchronously drive the first gear 14 to rotate. When the first gear 14 rotates, its teeth will mesh with the tooth grooves of the second gear 15, thereby driving the second gear 15 to rotate synchronously. When the second gear 15 rotates, it will synchronously drive the second threaded rod 16 to rotate. This method realizes their synchronous rotation. When the first threaded rod 13 and the second threaded rod 16 rotate, the two corresponding nuts 17 will also cooperate with the threads opened on the surface through the threads opened on the inner wall to realize the synchronous adjustment position of the two nuts 17. When the nuts 17 move, they will synchronously drive the connecting frame 18 and the clamping ring 19 to adjust. The slider 110 can be more stable when the clamping ring 19 is adjusted to prevent it from shifting when it is collided. The staff only needs to start the motor 12 to adjust the position of the clamping ring 19, thereby controlling its clamping of hardware parts of different sizes and the clamping force.
