[0024] refer to Figure 1As shown, an embodiment of the utility model provides an AR glasses optical module focusing knob torque testing device, including a base 1, a rotating mechanism 2, a torque acquisition mechanism 3 and a clamp 4.

[0025] The base 1 is a box-type structure, and a display screen 11 and a button 12 are provided at the front end of the base 1 .

[0026] refer to Figure 2 As shown, the rotating mechanism 2 includes a motor 21 and a carrying platform 22 .

[0027] The motor 21 is supported inside the base 1 by an adjustment plate 23. The output shaft of the motor 21 faces upward and is perpendicular to the ground. The adjustment plate 23 is slidably connected to the base 1 and can slide in the longitudinal direction relative to the base 1, which facilitates adjustment of the position of the motor 21 in the longitudinal direction. An adjustment frame 24 is also provided on the outside of the adjustment plate 23. The adjustment plate 23 and the adjustment frame 24 slide in the longitudinal direction, so that the adjustment plate 23 can slide in the longitudinal direction relative to the adjustment frame 24. The sliding direction of the adjustment plate 23 relative to the adjustment frame 24 is consistent with the sliding direction of the adjustment plate 23 relative to the base 1, and the adjustment frame 24 does not move when the adjustment plate 23 is slid in the longitudinal direction. The adjustment frame 24 also slides in the base 1 and can slide in the transverse direction relative to the base 1. The adjustment frame 24 and the adjustment plate 23 can slide synchronously in the transverse direction. That is, when the adjustment frame 24 is slid in the transverse direction, the adjustment frame 24 can drive the adjustment plate 23 to slide synchronously. In this way, the position of the motor 21 in the longitudinal and transverse directions can be adjusted. When the position of the motor 21 is adjusted to the right position, the adjustment plate 23 and the adjustment frame 24 can be locked.

[0028] A fixing flange 25 is provided on the upper side of the adjustment plate 23. A bearing is provided at the upper end of the fixing flange 25. A support plate 26 is provided on the upper side of the bearing. The support plate 26 is rotatable relative to the fixing flange 25. The output shaft of the motor 21 passes through the fixing flange 25 and is connected to the support plate 26, so that the motor 21 can drive the support plate 26 to rotate. The support plate 26 is also provided with a positioning hole. When assembling the equipment, ensure that the center of the positioning hole coincides with the axis of the motor 21. A Y-axis translation stage 27 is provided on the upper side of the support plate 26. An X-axis translation stage 28 is provided at the upper end of the Y-axis translation stage 27. The supporting platform 22 is disposed at the upper end of the X-axis translation stage 28. The Y-axis translation stage 27 can drive the X-axis translation stage 28 and the supporting platform 22 to move in the Y-axis direction (the Y-axis direction is also the longitudinal direction), and the X-axis translation stage 28 can drive the supporting platform 22 to move in the X-axis direction (the X-axis direction is also the transverse direction). Since the Y-axis translation stage 27 is fixedly connected to the support plate 26 , when the motor 21 drives the support plate 26 to rotate, it can drive the Y-axis translation stage 27 , the X-axis translation stage 28 and the carrying platform 22 to rotate synchronously.

[0029] Limit blocks are provided around the upper side of the carrying platform 22 , and the limit blocks around the upper side form a fixture installation area. The fixture 4 is set in the fixture installation area, and the workpiece to be measured is installed on the fixture 4.

[0030] refer to Figure 3 As shown, the torque acquisition mechanism 3 includes a column 31, a slide 32, a sensor positioning member 33, a torque sensor 34 and a screwdriver bit 35. The lower end of the column 31 is fixed to a position near the rear side of the base 1, and the slide 32 is slidably arranged on the column 31. The slide 32 can slide in the vertical direction of the column 31 (the vertical direction is also the Z-axis direction). After the slide 32 slides to the desired position, it can be locked by a screw. The sensor positioning member 33 is supported on the slide 32, the torque sensor 34 is arranged on the sensor positioning member 33, and the screwdriver bit 35 is arranged at the lower end of the torque sensor 34. A test area is formed between the screwdriver bit 35 and the fixture 4, and the axis of the screwdriver bit 35 coincides with the axis of the motor 21.

[0031] During the test, the workpiece to be tested is mounted on the fixture 4, and the X-axis translation stage 28 and the Y-axis translation stage 27 are adjusted so that the knob to be tested on the workpiece coincides with the bit 35. Then the slide 32 is adjusted so that the bit 35 abuts against the knob to be tested. Then, the motor 21 is started by pressing the button 12. The motor 21 drives the workpiece to rotate, and the torque sensor 34 obtains torque data in real time and stores the data. The test conditions can be set through the display screen 11 at the front end of the base 1, and some test data can be viewed.

[0032] This testing equipment can perform torque tests on knobs, which facilitates quality control and ensures user experience. It can also perform fatigue tests to simulate whether fatigue deformation and other problems will occur during repeated tightening, providing better protection for product quality.

[0033] The present invention is not limited to the above optional embodiments. Anyone can derive various other forms of products based on the inspiration of the present invention. The above specific embodiments should not be construed as limiting the scope of protection of the present invention. The scope of protection of the present invention shall be based on the scope defined in the claims, and the specification can be used to interpret the claims.
