DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific embodiments. The present invention is explained by means of the illustrative embodiments and descriptions of the present invention, but is not intended to be limiting of the present invention.

The two ends of a spring 9 are respectively connected to the support plate 6 and the wedge block 7. A separation push rod 11 is provided on the wedge block 7, and the separation push rod 11 passes through the support plate 6.

The positioning seat 3 is used to be inserted into the inner circle of the clutch hub 5.

[0030] The wedge block 7 is provided with an inclined surface, and a friction plate 10 is provided at the lower end of the wedge block 7, and the friction plate 10 has an angle with the horizontal direction.

[0031] Specifically, align the circular hole of the clutch hub 5 with the round head 4, put the clutch hub 5 into the round head 4, the inner circular boss of the clutch hub 5 matches the concave of the positioning seat 3, the bottom of the clutch hub 5 contacts the upper boss of the middle support column 2, and during the downward movement of the clutch hub 5, the side of the clutch hub 5 contacts the inclined surface of the wedge block 7, the clutch hub 5 drives the wedge block 7 to move outward, the spring 19 is compressed, and when the clutch hub 5 passes the inclined surface of the wedge block 7, the spring 19 provides power, the wedge block 7 moves toward the center, and the friction plate 10 presses the clutch hub 5. Since the friction plate 10 is an inclined surface, the friction plate 10 can clamp clutch hubs 5 of different sizes.

[0032] A disc 12 is rotatably provided on the platform 1 , and a gear 13 is provided on the disc 12 . The gear 13 is meshed with a gear 2 14 . The gear 2 14 is fixed on the rotating shaft of a motor 15 , and the motor 15 is fixed on the lower surface of the platform 1 .

[0033] Specifically, the motor 15 provides power, which is transmitted through the gear 1 13 and the gear 2 14 to drive the disc 12 to rotate.

[0034] Four separation arc plates 16 are provided on the side of the disc 12, and the four separation arc plates 16 are respectively used to drive the separation push rods 11 of the four groups of clamping devices.

[0035] Specifically, the side surface of the separation arc plate 16 is an inclined surface, and the disc 12 rotates forward. During the movement of the disc 12 from the fourth station to the first station, the inclined surfaces of the four separation arc plates 16 contact the round heads of the separation push rods 11 of the four clamping devices, driving the separation push rods 11 to move outward, thereby causing the wedge block 7 to move outward and the friction plate 10 to leave the clutch hub 5.

[0036] A detection column 17 is slidably disposed on the disc 12 , and two ends of a spring 18 are respectively connected to the disc 12 and the detection column 17 , and a shifting column 21 is disposed at the lower end of the detection column 17 .

[0037] A detection plate 19 is rotatably mounted on the detection column 17 , and two ends of a torsion spring 20 are respectively connected to the rotating shaft of the detection plate 19 and the detection column 17 .

[0038] The support frame 26 is arranged on the platform 1, and there are four torsion shafts 23. The torsion shafts 23 are rotatably arranged on the support frame 26. The two ends of the torsion spring 24 are respectively connected to the torsion shaft 23 and the support frame 26. The end of the torsion shaft 23 is provided with an inclined rotation plate 22, and the side of the inclined rotation plate 22 is provided with a transition plate 25. The transition plate 25 is fixed on the inner circular wall of the support frame 26. The inclined rotation plate 22 is provided with an inclined surface and a flat surface, and the flat surface of the inclined rotation plate 22 is flush with the lower flat surface of the transition plate 25.

[0039] Specifically, when the disc 12 rotates in the reverse direction, if the lever 21 contacts the inclined rotating plate 22, the lever 21 drives the inclined rotating plate 22 and the torsion shaft 23 to rotate in the forward direction, and the torsion spring 24 stores energy, so the inclined rotating plate 22 does not prevent the disc 12 from rotating in the forward direction; when the disc 12 rotates in the forward direction, if the lever 21 contacts the inclined surface of the inclined rotating plate 22, the transition plate 25 prevents the inclined rotating plate 22 from rotating, so the lever 21 drives the inclined surface of the inclined rotating plate 22 to move.

[0040] When the clutch hub 5 is inserted into the positioning seat 3, a square hole of the clutch hub 5 is placed in the detection column 17. When the disc 12 rotates in the opposite direction, the detection plate 19 automatically rotates on the detection column 17, and the detection plate 19 automatically contacts the side of the square hole of the clutch hub 5, thereby testing the transmission torque and strength performance of the first square hole of the clutch hub 5; when the disc 12 rotates forward, the lever 21 contacts the inclined surface of the inclined rotating plate 22, and the inclined surface of the inclined rotating plate 22 drives the lever 21 and the detection column 17 to move downward, the spring 18 is compressed, and the detection plate 19 moves to the clutch Below the disc hub 5, the disc 12 continues to rotate forward, and the lever 21 moves from the inclined surface of the inclined rotating plate 22 to the plane of the inclined rotating plate 22 and the lower plane of the transition plate 25. After the disc 12 rotates forward ninety degrees, the lever 21 disengages from the first transition plate 25, and the spring 18 provides power to insert the detection column 17 and the detection plate 19 into the second square hole of the clutch disc hub 5. The disc 12 rotates in the opposite direction again, thereby testing the transmission torque and strength performance of the second square hole of the clutch disc hub 5; similarly, the transmission torque and strength performance of the third and fourth square holes of the clutch disc hub 5 are tested.

[0041] The disc 12 is provided with a top arc-starting plate 27, a top rod 28 is slidably arranged on a slide seat 29, the slide seat 29 is fixedly arranged on the platform 1, the two ends of a spring 30 are respectively connected to the top rod 28 and the slide seat 29, a side of the top rod 28 is provided with an elastic bevel block 31, the top arc-starting plate 27 is used to drive the elastic bevel block 31, the upper end of the top rod 28 is provided with a top circular ring 32, the top circular ring 32 is used to eject the clutch disc hub 5, and the four separation arc plates 16 and the top arc-starting plate 27 are located in different planes.

[0042] Specifically, when the disc 12 moves from the fourth station to the first station, the friction plate 10 first leaves the clutch hub 5, and then the top arc plate 27 contacts the inclined surface of the spring-slope block 31. The top arc plate 27 drives the spring-slope block 31 and the push rod 28 to move upward, the spring three 30 is stretched, and the push rod 28 drives the top circular ring 32 to move upward, and the top circular ring 32 pushes the clutch hub 5 to move upward, so that the clutch hub 5 is located on the upper part of the inclined surface of the wedge block 7; when the disc 12 moves to the first station, the top arc plate 27 passes the spring-slope block 31, the spring three 30 pulls the push rod 28 to move downward, and the top circular ring 32 returns to its original state.

[0043] Working principle: in the original state, the detection plate 19 is in the upper position, the round hole of the clutch hub 5 is manually aligned with the round head 4, and the clutch hub 5 is placed in the round head 4. During the downward movement of the clutch hub 5, the side of the clutch hub 5 contacts the inclined surface of the wedge block 7, and the clutch hub 5 drives the wedge block 7 to move outward, and the spring 19 is compressed. When the clutch hub 5 passes the inclined surface of the wedge block 7, the spring 19 provides power, and the wedge block 7 moves toward the center. The friction plate 10 presses the clutch hub 5. Since the friction plate 10 is an inclined surface, the friction plate 10 can clamp clutch hubs 5 of different sizes. The inner circular boss of the clutch hub 5 matches the concave of the positioning seat 3, and the bottom of the clutch hub 5 contacts the upper boss of the middle support column 2, and the first square hole of the clutch hub 5 is placed in the detection column 17 and the slide seat 29.

[0044] The motor 15 provides power, which is transmitted through the gear 1 13 and the gear 2 14 to drive the disc 12 to rotate. The disc 12 has four workstations, which detect the transmission torque and strength performance of the four square holes of the clutch hub 5 in turn. Specifically, when the disc 12 rotates in the reverse direction, the detection plate 19 automatically rotates on the detection column 17, and the detection plate 19 automatically contacts the side of the square hole of the clutch hub 5, thereby testing the transmission torque and strength performance of the first square hole of the clutch hub 5; when the disc 12 rotates forward, the lever 21 contacts the inclined surface of the inclined plate 22, and the inclined surface of the inclined plate 22 drives the lever 21 and the detection column 17 to move downward, the spring 2 18 is compressed, and at the same time the detection plate 19 moves to the bottom of the clutch hub 5, and the disc 12 continues to rotate forward. , the lever 21 moves from the inclined surface of the inclined rotating plate 22 to the plane of the inclined rotating plate 22 and the lower plane of the transition plate 25. After the disc 12 rotates forward by ninety degrees, the lever 21 disengages from the first transition plate 25. The spring 18 provides power to insert the detection column 17 and the detection plate 19 into the second square hole of the clutch hub 5. The disc 12 rotates in the opposite direction again, thereby testing the transmission torque and strength performance of the second square hole of the clutch hub 5; similarly, the transmission torque and strength performance of the third and fourth square holes of the clutch hub 5 are tested.

[0045] When the disc 12 moves from the fourth station to the first station, the inclined surfaces of the four separation arc plates 16 contact the round heads of the separation push rods 11 of the four clamping devices, driving the separation push rods 11 to move outward, thereby causing the wedge block 7 to move outward, automatically causing the friction plate 10 to leave the clutch hub 5, and loosening the friction plate 10; then the top arc plate 27 contacts the inclined surface of the elastic bevel block 31, and the top arc plate 27 drives the elastic bevel block 31 and the push rod 28 to move upward, the spring three 30 is stretched, and the push rod 28 drives the top circular ring 32 to move upward, and the top circular ring 32 pushes the clutch hub 5 to move upward, so that the clutch hub 5 is located at the upper part of the inclined surface of the wedge block 7, and the clutch hub 5 that has been detected is automatically pushed out to the upper part of the inclined surface of the wedge block 7; when the disc 12 moves to the first station, the top arc plate 27 passes the elastic bevel block 31, the spring three 30 pulls the push rod 28 to move downward, and the top circular ring 32 returns to its original state.
