[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] See Figure 1-5 As shown, this embodiment provides an automatic torque testing machine, including a test platform 1. The test platform 1 is equipped with two sets of rotating mechanisms 2 and two sets of pressing mechanisms 3. The rotating mechanism 2 includes a torque testing mounting station 20 for mounting the lower part of the test component 4. The pressing mechanism 3 includes a vertically movable torque testing pressing column 30. The torque testing pressing column 30 is vertically aligned with the torque testing mounting station 20, used to press the upper part of the test component 4, and cooperates with the rotating mechanism 2 to apply torque to the test component 4. The test component 4 described herein is a twistable product, comprising an upper turntable assembly and a lower turntable assembly, the two parts being connected in series by a screw. Other forms of knob products are also included besides the above structure, but their structures will not be described in detail here. Through the vertically aligned cooperation of the rotating mechanism 2 and the pressing mechanism 3, the clamping and torque application of the test component 4 are achieved, avoiding errors and inconsistencies caused by manual operation, and improving the standardization and reliability of the test.
[0019] See Figure 4As shown, the rotating mechanism 2 includes a drive motor 21, a reducer 22, and a torque converter 23. The drive motor 21 is fixed to the lower part of the test bench 1, the reducer 22 is connected to the output end of the drive motor 21, and the torque converter 23 is connected to the output end of the reducer 22. A bushing 24 is connected to the output end of the torque converter 23, and a rotating clamp 25 is connected to the end of the bushing 24 away from the torque converter 23. A torque test mounting station 20 is provided on the upper part of the rotating clamp 25. The torque test mounting station 20 is used to accommodate the screw 40 of the test component 4. By adopting the transmission chain of drive motor 21 + reducer 22 + torque converter 23, precise torque control and stable output are achieved. At the same time, the modular design of bushing 24 and rotating clamp 25 facilitates the replacement of clamps of different specifications, enhancing the versatility and maintenance convenience of the equipment.
[0020] See Figure 4-5 As shown, the top end face of the rotary fixture 25 has circumferentially distributed rotation points 250, which engage with the grooves 410 on the lower part of the test component 4. Specifically, the rotation points 250 are used to accommodate the grooves 410 on the lower turntable 41 of the test component 4. The circumferentially distributed rotation points 250 on the top of the rotary fixture 25 engage with the grooves 410 on the lower turntable 41 of the test component 4, forming a rotation of the lower turntable assembly of the test component 4. The engagement between the rotary fixture 25 and the grooves 410 on the lower turntable 41 improves the accuracy of torque transmission and the reliability of test results.
[0021] The pressing mechanism 3 includes a mounting base 31, a telescopic cylinder 32, a fixing plate 33, and a slider 34. The mounting base 31 is fixed to the test bench 1, the telescopic cylinder 32 is fixed to one side of the mounting base 31, and the fixing plate 33 is fixed to the other side of the mounting base 31. The slider 34 is movably connected to the fixing plate 33 and connected to the output end of the telescopic cylinder 32. The pressing mechanism 3 drives the slider 34 to achieve linear reciprocating motion along the fixing plate 33 through the telescopic cylinder 32. It has a simple structure, fast response speed, and adjustable cylinder pressure to adapt to the needs of different components, thus improving the flexibility and adaptability of the equipment. When the slider 34 presses against the top of the torque test pressing column 30 and abuts against the anti-rotation part 300, it forms an anti-rotation mechanism against the torque test pressing column 30.
[0022] The fixed plate 33 has a through-type assembly opening 330, and a sliding groove 331 is provided on its side; the connecting end of the slider 34 is embedded in the sliding groove 331; the top end of the torque test pressure column 30 is hung in the assembly opening 330. The assembly opening 330 and the sliding groove 331 on the fixed plate 33 are designed so that the torque test pressure column 30 is suspended on the fixed plate 33, and the slider 34 moves linearly along the sliding groove 331 to form a guide.
[0023] The torque testing pressure column 30 has an anti-rotation part 300 at its top end, which extends outside the mounting opening 330 of the fixing plate 33 and cooperates with the slider 34 to prevent the torque testing pressure column 30 from rotating. The bottom end of the torque testing pressure column 30 has circumferentially distributed insertion bodies 301. The insertion bodies 301 are inserted into the holes 420 of the upper turntable 42 of the test component 4, forming an anti-rotation mechanism against the upper turntable assembly of the test component 4. The anti-rotation part 300 is designed to prevent the pressure column from rotating during the test, ensuring that the downward force is applied perpendicularly to the test component 4.
[0024] This automatic torque testing machine also includes a torque machine control box 5 and a start switch 6. The torque machine control box 5 is mounted on the test bench 1 and is electrically connected to the rotating mechanism 2 and the pressing mechanism 3. The torque machine control box 5 centrally controls the rotating mechanism 2 and the pressing mechanism 3, automating the testing process, reducing manual intervention, and improving testing efficiency and consistency. The start switch 6 is mounted on the mounting base 31 and is electrically connected to the torque machine control box 5. The start switch 6 is integrated into the mounting base 31, making operation convenient and ergonomic, while also avoiding the risk of accidental activation and improving equipment safety.
[0025] This automatic torque testing machine also includes a first proximity switch 7 for detecting the position of the slider 34 and a second proximity switch 8 for detecting the completion or abnormality of the test. Both the first proximity switch 7 and the second proximity switch 8 are electrically connected to the torque machine's electrical control box 5. The first proximity switch 7 monitors the position of the slider 34 in real time, ensuring that the slider 34 is pressed tightly against the lower pressure column and abuts against the anti-rotation part 300 before starting the torque test; the second proximity switch 8 detects the completion or abnormality of the test in real time.
[0026] The working process of this automatic torque testing machine is as follows: Lift the torque testing pressure column 30, place the test component 4 in the torque testing installation position 20 of the rotating mechanism 2, and engage the groove 410 of the lower turntable 41 of the test component 4 with the rotation point 250 of the rotating fixture 25; at the same time, the connector 301 of the torque testing pressure column 30 is inserted into the hole 420 of the upper turntable 42 of the test component 4. When the equipment is started, the telescopic cylinder 32 pushes the slider 34 to move along the fixed plate 33. The slider 34 abuts against the anti-rotation part 300 and presses the top of the torque test pressure column 30. The anti-rotation part 300 and the slider 34 cooperate to prevent the pressure column from rotating. The drive motor 21 in the rotating mechanism 2 drives the rotating clamp 25 to rotate through the reducer 22 and the torque generator 23, thereby applying torque to the lower turntable assembly of the test component 4. The torque generator 23 detects the torque value in real time, and the test data is transmitted to the electrical control box for processing and display. After the test is completed, the cylinder retracts, the rotating mechanism resets, the torque test pressure column 30 is lifted, and the test component 4 is taken out.
