[0023] Please see Figures 1 to 3 This invention provides a torsion testing device for electronic devices, comprising: A machine base 10 is provided with a fixed frame 11 and a workpiece clamping mechanism 12. The workpiece clamping mechanism 12 includes a movable clamping assembly 13 and a fixed clamping assembly 14. The movable clamping assembly 13 is rotatably mounted on the fixed frame 11. The fixed clamping assembly 14 is mounted on the machine base 10 and located on one side of the movable clamping assembly 13. A clamping space 17 is formed between the fixed clamping assembly 14 and the movable clamping assembly 13. The fixed clamping assembly 14 is movably connected to the machine base 10 and can move closer to or further away from the movable clamping assembly 13. The fixed clamping assembly 14 and the movable clamping assembly 13 cooperate to clamp the workpiece on opposite sides. A rotary drive assembly 20 is mounted on the fixed frame 11 and is driven to the movable clamping assembly 13 via a torque sensor 21. The rotary drive assembly 20 drives the torque sensor 21 and the movable clamping assembly 13 to rotate together. A control processing module (not shown) is disposed within the machine tool 10 and is signal-connected to the rotary drive assembly 20 and the torque sensor 21. The display 30 is mounted on the machine base 10 and is signal-connected to the control processing module.

[0024] The working principle of an angle torsion testing device according to an embodiment of the present invention is explained below: The workpiece is placed in the clamping space 17, with its two sides arranged on the fixed clamping assembly 14 and the movable clamping assembly 13 respectively. The clamping seat 15 of the fixed clamping assembly 14 can be adjusted to accommodate workpieces of different sizes.

[0025] The control processing module sends control signals to the rotary drive assembly 20 based on the requirements of the test angle, test rotation speed, and number of tests. The rotary drive assembly 20 drives the torque sensor 21 and the clamping seat 15 of the movable clamping assembly 13 to rotate based on the control signals. The clamping seat 15 of the movable clamping assembly 13 will apply torque to the workpiece, and the torque applied to the workpiece can be detected by the torque sensor 21, thereby completing the acquisition of torque data. The torque data is then transmitted to the control processing module for processing.

[0026] The control and processing module can be a computer, a main control board, etc., and is not limited to this example. The display 30 is used to display the result of the control processing module processing the torque data. The method of processing the torque data is a technique known to those skilled in the art and will not be described in detail here.

[0027] The signal connection method mentioned in this embodiment can be implemented using a wired connection.

[0028] In some optional embodiments, both the movable clamping assembly 13 and the fixed clamping assembly 14 include a clamping base 15 and a plurality of clamping structures 16. The clamping base 15 of the movable clamping assembly 13 is rotatably mounted on the fixed frame 11, and the clamping base 15 of the fixed clamping assembly 14 is movably mounted on the machine base 10 and located on one side of the clamping base 15 of the movable clamping assembly 13. A clamping structure is formed between the clamping base 15 of the fixed clamping assembly 14 and the clamping base 15 of the movable clamping assembly 13. The clamping space 17; the clamping base 15 is provided with a transverse adjustment track 151, which extends perpendicularly from the clamping base 15 of the movable clamping assembly 13 to the clamping base 15 of the fixed clamping assembly 14; the clamping structure 16 includes a clamping member 161 and an adjusting member 162, the adjusting member 162 being movably engaged with the transverse adjustment track 151, and the clamping member 161 being vertically and flexibly disposed on the adjusting member 162 for pressing the workpiece onto the clamping base 15. After the workpiece is placed in the clamping space 17, the two sides of the workpiece are respectively arranged on the clamping base 15 of the fixed clamping assembly 14 and the clamping base 15 of the movable clamping assembly 13. Then, the adjusting member 162 is adjusted relative to the transverse adjustment track 151 so that the clamping member 161 is arranged above the workpiece. Subsequently, the clamping member 161 descends along the adjusting member 162, thereby pressing the workpiece onto the clamping base 15.

[0029] Please see Figure 4In some optional embodiments, a control box 40 is provided on the machine base 10, and an operation button assembly 41 is provided on the control box 40. The operation button assembly 41 is signal-connected to the control processing module. The control box 40 is covered on the outside of the fixed frame 11, and the display 30 is disposed on the control box 40. The rotary drive assembly 20 and the torque sensor 21 are located inside the control box 40. The operation button assembly 41 facilitates operation by the operator. The control box 40 can protect the rotary drive assembly 20 and the torque sensor 21 from dust. In this embodiment, an electrical control chamber is formed inside the machine base 10, and the control processing module is disposed inside the electrical control chamber. A cooling fan assembly 50 communicating with the electrical control chamber and an interface assembly 51 for electrical connection with the control processing module are provided on one side of the machine base 10.

[0030] In some alternative implementations, the bottom of the machine base 10 is provided with a plurality of casters 52 and a plurality of adjustable feet 53 to facilitate the movement and fixation of the machine base 10.

[0031] Please see Figure 5 In some optional embodiments, the clamping seat 15 of the movable clamping assembly 13 is connected to a sensing element 152; a position detection assembly is provided on the fixed frame 11, which includes an intermediate detection sensor 111 and two extreme position detection sensors 112. One extreme position detection sensor 112, the intermediate detection sensor 111, and the other extreme position detection sensor 112 are sequentially arranged on the fixed frame 11 around the rotation axis of the movable clamping assembly 13. The intermediate detection sensor 111 and the two extreme position detection sensors 112 are all inductively engaged with the sensing element 152, and both are signal-connected to the rotation drive assembly 20. When the clamping seat 15 of the movable clamping assembly 13 is in its initial position relative to the clamping seat 15 of the fixed clamping assembly 14, the sensing element 152 is inductively engaged with the intermediate detection sensor 111. At this time, the clamping seats 15 of the movable clamping assembly 13 and the clamping seats 15 of the fixed clamping assembly 14 are approximately parallel, and the workpiece has not yet been subjected to torque.

[0032] The function of the limit position detection sensor 112 can be designed according to actual needs. For example, in one embodiment, when the clamping seat 15 of the movable clamping assembly 13 rotates to the limit position relative to the clamping seat 15 of the fixed clamping assembly 14, the limit position detection sensor 112 and the sensing element 152 are inductively engaged. If the clamping seat 15 of the movable clamping assembly 13 continues to rotate away from the initial position, it may cause damage to the workpiece. Thus, the arrangement of the limit position detection sensor 112 prevents excessive rotation. Of course, in other embodiments, the position of the limit position detection sensor 112 can be arranged in a suitable position according to the detection requirements, so that when the clamping seat 15 of the movable clamping assembly 13 rotates to the test angle triggered by the sensing element 152, the workpiece just bears the predetermined test torque. Therefore, the rotary drive assembly 20 drives the clamping seat 15 of the movable clamping assembly 13 to rotate back and forth to the test angle, so that the workpiece continuously bears the predetermined test torque. During the test, it is necessary to record: the number of tests, the rotation speed of the clamping seat 15 of the movable clamping assembly 13 driven by the rotary drive assembly 20, the interval angle between the limit position detection sensor 112 and the intermediate detection sensor 111 relative to the rotation axis of the clamping seat 15 of the movable clamping assembly 13, and the state of the workpiece, so as to determine whether the workpiece meets the requirements.

[0033] It should be noted that the specific structure of the intermediate detection sensor 111 and the extreme position detection sensor 112 can be designed according to actual needs. For example, the intermediate detection sensor 111 and the extreme position detection sensor 112 can be photoelectric sensors, infrared sensors, proximity switches, etc., while the sensing element 152 is selected according to the type of sensor.

[0034] In addition, in this embodiment, the fixed frame 11 is provided with an arc-shaped adjustment track 113 arranged around the rotation axis of the clamping seat 15 of the movable clamping assembly 13. The intermediate detection sensor 111 and the extreme position detection sensor 112 are locked to the arc-shaped adjustment track 113 by threaded locking parts. When the threaded locking parts are loosened, the intermediate detection sensor 111 and the extreme position detection sensor 112 can adjust their positions relative to the arc-shaped adjustment track 113 according to the actual test requirements.

[0035] Please see Figure 6In some optional embodiments, the fixed frame 11 is provided with an angle marking scale 114 arranged around the rotation axis of the movable clamping assembly 13; the clamping base 15 is connected to an angle indicator 153, the angle indicator 153 and the angle marking scale 114 are positioned correspondingly. When the clamping base 15 of the movable clamping assembly 13 rotates, the rotation angle of the clamping base 15 of the movable clamping assembly 13 can be determined by comparing the angle indicator 153 and the angle marking scale 114, which is convenient for calibrating test data and accurately judging the angle, and helps to improve test accuracy.

[0036] Please see Figure 7 In some optional embodiments, the lateral adjustment track 151 includes several adjustment grooves disposed on the clamping base 15. A limiting part 1621 is provided at the bottom of the adjustment member 162, and the limiting part 1621 is slidably disposed within the adjustment groove to prevent the adjustment member 162 from disengaging from the adjustment groove. When the clamping member 161 is pressed against the workpiece, the limiting part 1621 presses against the inner wall of the adjustment groove, thereby preventing the adjustment member 162 from disengaging from the adjustment groove. In this embodiment, the adjustment member 162 is a threaded member, and the clamping member 161 is threadedly engaged with the threaded member. By rotating the clamping member 161, the clamping member 161 is driven to rise and fall relative to the adjustment member 162.

[0037] In some alternative embodiments, both the movable clamping assembly 13 and the fixed clamping assembly 14 include a plurality of clamping structures 16 arranged sequentially along the extension direction of the transverse adjustment track 151. The plurality of clamping structures 16 can more stably clamp the workpiece, and the plurality of clamping structures 16 can adjust their position relative to the transverse adjustment track 151 according to workpieces of different sizes, thereby stably clamping the workpiece.

[0038] In some optional embodiments, the clamping base 15 is provided with position marking scales 154 arranged along the extension direction of the transverse adjustment track 151. When the clamping bases 15 of the movable clamping assembly 13 and the clamping bases 15 of the fixed clamping assembly 14 are placed on both sides of the workpiece, the central axis of the workpiece needs to be parallel to the direction from the clamping bases 15 of the movable clamping assembly 13 and the clamping bases 15 of the fixed clamping assembly 14, and the central axis and the rotation axis of the clamping base 15 of the movable clamping assembly 13 need to be on the same vertical plane and parallel to each other. Preferably, the central axis and the rotation axis of the clamping base 15 of the movable clamping assembly 13 are on the same straight line. If there is an angular deviation in the central axis of the workpiece, it can easily lead to uneven force on the workpiece, affecting the test structure. Therefore, the position marking scales 154 can be used to determine whether the workpiece is tilted.

[0039] In some optional embodiments, the clamping structure 16 further includes a lifting guide post 163 and a support block 164. The lifting guide post 163 is disposed on the clamping seat 15, and the support block 164 is movably disposed on the lifting guide post 163. The support block 164 is located on the side of the adjusting member 162 away from the clamping space. The clamping member 161 includes a clamping plate 1611 and a lowering member 1612. The clamping plate 1611 and the lowering member 1612 are movably disposed on the adjusting member 162 from bottom to top. The clamping plate 1611 extends out to both sides of the adjusting member 162. The support block 164 is also located between the clamping plate 1611 and the top of the clamping seat 15. The support block 164 is mainly used to adjust the force balance of the adjusting member 162. Without the support block 164, the force applied by the clamping member 161 to the workpiece may not be perpendicular to the surface of the clamping seat 15, affecting the stability of the clamping. The design of the liftable support block 164 ensures that the support block 164 is at the same height as the workpiece. When the pressing member 1612 presses down, the clamping plate 1611 presses down on both the support block 164 and the workpiece. The pressing member 1612 is positioned between the position where the support block 164 abuts against the clamping plate 1611 and the position where the workpiece abuts against the clamping plate 1611. This ensures that the downward pressure of the clamping plate 1611 applies a force perpendicular to the clamping base 15 to the workpiece and the support block 164, resulting in a more stable and balanced force on the workpiece and a more stable clamping.

[0040] The lifting guide column 163 can be a threaded guide column, and the support block 164 can be threadedly engaged with the threaded guide column. The bottom end of the lifting guide column 163 abuts against the top of the clamping base 15. When the adjusting member 162 moves along the transverse adjusting track 151, both the lifting guide column 163 and the support block 164 can move with the adjusting member 162. By rotating the threaded guide column, the support block 164 can be raised or lowered, while the bottom end of the lifting guide column 163 remains abutting against the top of the clamping base 15; this is not a limited example.

[0041] In some optional embodiments, both the movable clamping assembly 13 and the fixed clamping assembly 14 further include a mounting base 18. The mounting base 18 of the movable clamping assembly 13 is rotatably mounted on the fixed frame 11. The rotation drive assembly 20 is driven to connect with the clamping seat 15 of the movable clamping assembly 13 through the mounting base 18. The clamping seat 15 of the movable clamping assembly 13 is vertically and flexibly mounted on the corresponding mounting base 18. The mounting base 18 of the fixed clamping assembly 14 is movably mounted on the fixed frame 11. The clamping seat 15 of the fixed clamping assembly 14 is vertically and flexibly mounted on the corresponding mounting base 18. In this embodiment, the sensor 152 and the angle indicator 153 are both mounted on the mounting base 18, and the rotation drive assembly 20 is driven to connect with the mounting base 18. Due to the different thicknesses of the workpieces, when a thicker workpiece is clamped on the clamping base 15, the central axis of the workpiece will rise relative to the rotation axis of the clamping base 15. By adjusting the height of the clamping base 15 relative to the mounting base 18, the central axis of the workpiece will be closer to the rotation axis of the mounting base 18, so that the central axis of the workpiece will not deviate too far from the rotation axis of the mounting base 18, which would result in the applied torque not meeting the requirements.

[0042] The adjustment method of the clamping base 15 relative to the mounting base 18 can be designed according to actual needs. For example, the mounting base 18 can be provided with several lifting slides, and the clamping base 15 can be provided with several lifting threaded locking parts. The lifting threaded locking parts pass through the lifting slides and are then locked in place with the clamping base 15. Alternatively, a translation drive module (such as an electric cylinder, a lead screw drive module, etc.) can be provided on the mounting base 18 to drive the clamping base 15 to move up and down precisely.

[0043] Similarly, the adjustment method of the mounting base 18 of the fixed clamping assembly 14 relative to the machine base 10 can be designed according to actual needs. For example, several translational slides can be provided on the mounting base 18, and several translational threaded locking parts can be provided on the machine base 10. The translational threaded locking parts pass through the translational slides and then engage with the machine base 10 by threads, thereby pressing the mounting base 18 onto the machine base 10. Alternatively, a translational drive module (such as an electric cylinder, a lead screw drive module, etc.) can be provided on the machine base 10, and the mounting base 18 can be precisely translated by the translational drive module.

[0044] In some alternative embodiments, a pressure elastic pad 1613 is provided at the bottom of the clamping member 161. The pressure elastic pad 1613 can provide a cushioning effect to prevent the clamping member 161 from damaging the workpiece. The pressure elastic pad 1613 can be a rubber pad or a silicone pad. In this embodiment, the pressure elastic pad 1613 is provided at the bottom of the clamping plate 1611.
