The positioning column 6 is vertically fixed to the center of the top surface of the processing table 1. The positioning column 6 is cylindrical. A pair of slide grooves 11 arranged radially along the positioning column 6 are opened on the top surface of the processing table 1. The two slide grooves 11 are distributed on both sides of the positioning column 6. A pair of first slide blocks 2 are slidably connected to the inner side walls of the two first slide grooves 11 respectively. The top surfaces of the two first slide blocks 2 are fixed with concave frames 3. The outer side walls of the concave frames 3 are horizontally installed with first motors 31. The output end of the first motor 31 is coaxially fixed to the concave frame 3. The rotating roller 32 is rotatably matched with the inner wall of the concave frame 3. A plurality of tooth blocks 33 are detachably mounted on the outer circumference of the rotating roller 32 by bolts. The plurality of tooth blocks 33 are evenly spaced along the outer circumference of the rotating roller 32. The plurality of tooth blocks 33 can respectively cooperate with different gears to be measured and be clamped in the gear teeth of the gear to be measured. The driving mechanism 4 is arranged on the side wall of the processing table 1. The driving mechanism 4 can make the two first sliders 2 move toward or away from each other, so that the tooth blocks 33 are clamped in the gear teeth of the gear to be measured or separated from the gear to be measured. The first motor 31 adopts a brake motor.

[0028] By sleeve-arranging the gear to be tested outside the positioning column 6 and adjusting the position, the driving mechanism 4 is used to drive the two first slide blocks 2 to move toward each other, so that the tooth blocks 33 on the two first slide blocks 2 are clamped in the gear teeth of the gear to be tested to fix the gear to be tested, so that the gear to be tested remains stable during the detection process. When testing gears to be tested with different outer sizes, the first motor 31 can be started to drive the rotating roller 32 to rotate, so that the tooth blocks 33 on the outer circumference of the rotating roller 32 that match the gear to be tested rotate to the specified position, so that gears to be tested of different sizes can be clamped and fixed, reducing the trouble of replacing the fixture and improving the detection efficiency.

[0032] The gear to be tested is sleeved on the outside of the positioning column 6 and placed on the processing table 1. The concave plate 61 will drive the ball 62 to contact the inner wall of the gear to be tested under the elastic force of the spring 63. The position of the placed gear to be tested is adjusted through the cooperation of the three balls 62, so that the gear to be tested and the positioning column 6 remain coaxial, so that the two tooth blocks 33 can clamp and fix the gear to be tested from both sides.

[0033] like Figure 1 and Figure 5 As shown, a detection mechanism 5 for performing hardness detection on the gear to be tested is also provided on the top surface of the processing table 1. The detection mechanism 5 includes a support frame 51, a hardness tester 52 and an electric push rod 53. The support frame 51 is vertically fixed on the top surface of the processing table 1. The support frame 51 is L-shaped. The side walls of the support frame 51 are vertical. The top wall of the support frame 51 is horizontal and extends to the top of the positioning column 6. The electric push rod 53 is slidably installed on the bottom surface of the top wall of the support frame 51. The output end of the electric push rod 53 is vertically downwardly arranged, and the hardness tester 52 is installed on the output end of the electric push rod 53.

[0034] When testing the gear hardness, the hardness tester 52 is moved to a specified position by moving the electric push rod 53, and then the electric push rod 53 is started to drive the hardness tester 52 to move down to contact the gear to be tested, so that the hardness of the gear to be tested can be tested by the hardness tester 52.

[0035] like Figure 5 and Figure 6As shown, a rotating motor 54 is vertically installed on the top surface of the top wall of the support frame 51, and a rotating shaft 541 coaxial with the positioning column 6 is coaxially fixed to the output end of the rotating motor 54, and a connecting plate 55 located at the bottom of the top wall of the support frame 51 is horizontally fixed to the end of the rotating shaft 541 away from the rotating motor 54, and the electric push rod 53 is slidably installed on the bottom surface of the connecting plate 55. A moving component 56 that can drive the electric push rod 53 to move is provided on the connecting plate 55. The moving component 56 includes a third motor 561, a second screw rod 562 and a second slider 563. A through groove arranged radially along the positioning column 6 is opened on the connecting plate 55. 551, the third motor 561 is horizontally installed on the outer wall of the connecting plate 55 close to one end of the rotating shaft 541, the second screw rod 562 is horizontally rotatably connected to the inner wall of the through slot 551, one end of the second screw rod 562 is coaxially fixed to the output end of the third motor 561, the second slider 563 is sleeved on the outer wall of the second screw rod 562, the second slider 563 is threadedly matched with the second screw rod 562, the second slider 563 is slidably matched with the inner wall of the through slot 551, the electric push rod 53 is vertically installed on the bottom surface of the second slider 563, and the rotating motor 54 and the third motor 561 are both brake motors.

[0036] During the gear hardness testing process, the rotating motor 54 is started to drive the rotating shaft 541 and the connecting plate 55 to rotate, and the connecting plate 55 drives the electric push rod 53 to adjust the position along the circumference of the positioning column 6. The third motor 561 is started to drive the second screw rod 562 to rotate, so that the second slider 563 drives the electric push rod 53 to move the position along the radial direction of the positioning column 6. The cooperation of the rotating motor 54 and the third motor 561 can realize the adjustment of the detection position of the hardness tester 52, so that the hardness tester 52 can be moved to the specified position according to the detection needs to perform gear hardness testing.

[0037] like Figure 1 and Figure 6 As shown, an annular plate 57 surrounding the outside of the connecting plate 55 is fixedly connected to the bottom surface of the top wall of the support frame 51, the annular plate 57 is coaxially arranged with the rotating shaft 541, an annular groove 571 is opened on the inner wall of the annular plate 57, and a limiting ball 552 extending into the annular groove 571 is fixedly connected to the outer wall of the connecting plate 55 away from the third motor 561 through a connecting rod, and the limiting ball 552 slides in cooperation with the inner wall of the annular groove 571.

[0038] When the rotating motor 54 drives the connecting plate 55 to rotate, the limiting ball 552 will slide along the inner wall of the annular groove 571. The limiting ball 552 cooperates with the inner wall of the annular groove 571 to limit the rotating connecting plate 55 and support the stationary connecting plate 55, so as to keep the connecting plate 55 horizontal, reduce the possibility of deformation of the connecting plate 55, and improve the stability of the connecting plate 55.

[0039] Working principle: When testing the hardness of a gear, the gear to be tested is sleeved on the outside of the positioning column 6 and placed on the processing table 1. The concave plate 61 on the positioning column 6 will make the ball 62 contact the inner wall of the gear to be tested under the elastic force of the spring 63. The placement position of the gear to be tested is adjusted through the cooperation of multiple balls 62, so that the gear to be tested and the positioning column 6 remain coaxial. Then, the second motor 41 is started to drive the first screw rod 42 to rotate and cause the two first sliders 2 to move toward each other, so that the tooth blocks 33 on the top surfaces of the two first sliders 2 that match the gear to be tested are clamped in the gear teeth of the gear to be tested to clamp and fix the gear to be tested. Then, the electric push rod 53 is started to drive the hardness tester 52 to move down and contact the gear to be tested, and the hardness test of the gear to be tested is performed by the hardness tester 52. When it is necessary to detect gears to be tested with different shapes and sizes, the first motor 31 can be started to drive the rotating roller 32 to rotate, so that the clamping tooth block 33 on the outer circumference of the rotating roller 32 that matches the gear to be tested can be rotated to a specified position, so that the gears to be tested with different shapes and sizes can be clamped and fixed, reducing the trouble of replacing the fixture and improving the detection efficiency; During the gear hardness testing process, the rotating motor 54 can be started to drive the rotating shaft 541 and the connecting plate 55 to rotate, and the connecting plate 55 can drive the electric push rod 53 to move along the circumferential direction of the positioning column 6. The third motor 561 can be started to drive the second screw rod 562 to rotate, so that the second slider 563 drives the electric push rod 53 to move along the radial direction of the positioning column 6. The cooperation of the rotating motor 54 and the third motor 561 can conveniently adjust the detection position of the hardness tester 52, so that the hardness tester 52 can perform hardness testing at different positions of the gear to be tested.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
