Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] As shown in Figures 1 to 7 The utility model provides a kind of device and method for detecting clamping and electrically connecting potentiometer, including base 1, the top of base 1 is respectively fixedly installed with first fixed plate 2, second fixed plate 8 and third fixed plate 11 from left to right, the left side wall of first fixed plate 2 is fixedly installed with motor 3, the output shaft of motor 3 penetrates to the right side of first fixed plate 2 and is fixedly installed with shaft coupling 5, shaft coupling 5 is fixedly installed with chuck 6 on the right side, the outer wall of chuck 6 is fixedly installed with pointer 7, the right side of second fixed plate 8 is fixedly provided with clamping groove 10, and the top of third fixed plate 11 is threadedly sleeved with screw rod wrench 12;
[0026] Potentiometer 20 is clamped on the right side of clamping groove 10, three groups of terminal posts 22 are arranged on the top of potentiometer 20, base 13 is arranged between potentiometer 20 and screw rod wrench 12, step hole 14 is formed on the left side of base 13, blind hole 15 is formed in the middle of step hole 14, notch 24 is formed on the top edge of step hole 14, three groups of round holes 16 are evenly formed in the inside of notch 24, thimble 18 is arranged in the inside of three groups of round holes 16, and each group of thimble 18 is in abutment with terminal post 22.
[0027] When the staff needs to detect the potentiometer, the staff first rotates the dial 9, aligns the 0 position on the dial 9 with the pointer 7, and then fixes the dial 9 and the second fixed plate 8 through the screw. Then the potentiometer 20 and the base 13 are assembled. First, the staff aligns the terminal post 22 at the top of the potentiometer 20 with the thimble 18, and then inserts the left end of the potentiometer 20 into the clamping groove 10 and the right end of the potentiometer 20 into the stepped hole 14. At this time, the staff can press the base 13 with one hand to ensure that the base 13 and the second fixed plate 8 clamp and fix the potentiometer 20, and rotate the lead screw wrench 12 with the other hand to make the lead screw wrench 12 displace to the left. With the left displacement of the lead screw wrench 12, the left end of the lead screw wrench 12 abuts against the positioning hole 25, and the base 13 is further fixed between the second fixed plate 8 and the base 13 by the left force provided by the lead screw wrench 12. After the fixing is completed, one end of the mandrel 21 is located in the blind hole 15, and the other end is located in the counter interface 23. The thimble 18 abuts against the terminal post 22 through the elastic potential of the spring 19 to realize conduction. Further, the staff turns on the test power supply and starts the motor 3 through the motor controller 4 to drive the chuck 6 and the pointer 7 to rotate. The rotation of the pointer 7 on the surface of the dial 9 facilitates the staff to accurately read the rotation angle and displacement of the potentiometer. The rotation of the chuck 6 drives the mandrel 21 to rotate. When the mandrel 21 rotates, the resistance inside the potentiometer 20 changes. The staff detects the potentiometer 20 through the measuring device connected by the thimble 18. The staff observes the voltage linearity of the multimeter. If the pointer-type voltmeter needle moves at a constant speed with the rotation of the mandrel 21, it is determined that the potentiometer is qualified. If the potentiometer voltage is interrupted, large and small, does not change with the change of angle, and does not reach the upper limit of the voltage, it is determined that the potentiometer is unqualified.
[0028] The rotation angle or displacement of the potentiometer is accurately controlled by the motor controller, and the angle dial and the pointer are provided to facilitate the staff to accurately read the position of the potentiometer, improve the detection accuracy and reliability, and at the same time, the spring thimble and the potentiometer terminal post are elastically connected to realize conduction without direct contact with the potentiometer, effectively avoiding the risk of damage to the potentiometer caused by manual operation. In addition, the device fixes the potentiometer in the stepped hole through the design of the base and connects the spring thimble and the terminal post to effectively avoid the problem of potentiometer burnout caused by miswiring when connecting the potentiometer and the detection device. Finally, the chuck 6 drives the mandrel 21 to rotate smoothly and uniformly, so that the staff can detect the smooth line of the potentiometer 20 through the pointer voltmeter and the digital multimeter to ensure the detection quality and improve the detection efficiency.

[0030] Since the one end of the mandrel 21 is drivingly connected with the chuck 6 through the butt joint 23, the mandrel 21 rotates synchronously when the chuck 6 rotates, and further, the adjustment of the internal resistance change of the potentiometer 20 is realized through the mandrel 21, so that the staff can detect the potentiometer 20 through the rotation of the mandrel 21.
[0031] The right side of the base 13 is provided with a positioning hole 25, and the left end of the screw wrench 12 abuts against the positioning hole 25.
[0032] Through the arrangement of the positioning hole 25, the screw wrench 12 will be displaced to the left when rotating, and finally abuts against the positioning hole 25 with the left movement of the screw wrench 12, and the arrangement of the positioning hole 25 can ensure that the base 13 and the screw wrench 12 are aligned with each other, and the problem of deviation during clamping will not occur.
[0033] The inside of the circular hole 16 is fixedly installed with a sleeve 17, and the thimble 18 is movably installed in the inside of the sleeve 17.
[0034] The right end of the thimble 18 is elastically connected with the sleeve 17 through the spring 19, and the left end of the thimble 18 abuts against the terminal post 22.
[0035] When the base 13 is displaced to the left, the thimble 18 and the terminal post 22 will be in contact with each other, and further, with the continuous left displacement of the base 13, the thimble 18 will be pushed to the right by the terminal post 22, and the elastic potential energy of the spring 19 can ensure that the thimble 18 and the terminal post 22 are closely attached and reliably conduct electricity.
[0036] The left side of the second fixed plate 8 is rotatably installed with a dial 9, the dial 9 and the second fixed plate 8 are locked by screws, and the 0 position of the dial 9 is aligned with the pointer 7.
[0037] Through the rotation of the dial 9, the staff can rotate the dial 9 after each test to ensure that the dial 9 and the pointer 7 are aligned, and the structure is simple and convenient to operate through the screw fixation.
[0038] The base 13 is made of nylon material, and the right end of the thimble 18 is welded with a cable, and the other end of the cable is connected with a pointer type voltmeter, a digital multimeter and a direct current power supply respectively.
