In this way, the workpiece can be fully clamped and fixed, and the workpiece can be limited in the longitudinal and transverse directions without causing excessive mechanical damage to the workpiece, so as to ensure that the workpiece does not shake or deflect during its rotation, thereby ensuring that the end face runout and side runout of the workpiece can be transmitted outward with high precision through the runout transmission rod to ensure the accuracy of runout detection.

[0034] The pushing assembly comprises a first mounting plate 301 which can be lifted and installed on the frame on the lower side of the group of pulley transmission belts 2, a corresponding rigid cylinder 302 can be rotatably installed on the first mounting plate 301, the rigid cylinder 302 is driven by a corresponding first lifting drive mechanism 303, a corresponding partition 304 is fixedly connected to the lower part of the top of the rigid cylinder 302, a plurality of corresponding guide holes are arranged in a circular array on the rigid cylinder 302 on the upper side of the partition 304, corresponding tightening rods 305 are movably inserted in the guide holes, a corresponding elastic compression block 306 is fixedly installed in the rigid cylinder 302 on the upper side of the partition 304, and the top of the elastic compression block 306 is located on the upper side of the top of the rigid cylinder 302;

[0035] A pressing assembly, comprising a second mounting plate 401 which can be lifted and lowered on the frame 1 on the upper side of the pulley transmission belt 2, a corresponding pressing fixture 402 can be rotatably mounted on the second mounting plate 401, the pressing fixture 402 is directly opposite to the elastic compression block 306, a cylindrical elastic member 403 with a bottom located at the lower side of the bottom of the pressing fixture 402 is fixedly sleeved on the periphery of the pressing fixture 402, and the pressing fixture 402 is driven by a corresponding second lifting drive mechanism 404;

[0036] The jumping transmission mechanism 5 comprises a fixed plate 501 movably mounted on the frame 1, a corresponding jumping transmission rod 503 is fixedly mounted on the fixed plate 501 through a corresponding flexible connection component 502, and a guide wheel 504 located between the pushing component and the pressing component is horizontally and rotatably mounted at the end of the jumping transmission rod 503;

[0037] The driving mechanism comprises a transmission wheel 601 fixed to the bottom side of the rigid cylinder 302, and the transmission wheel 601 is connected to the output shaft end of the corresponding driving motor 602 by belt transmission; the workpiece 7 enters between the pushing assembly and the pressing assembly under the transportation of a set of the pulley transmission belts 2; the first lifting driving mechanism 303 drives the rigid cylinder 302 upward to lift the workpiece 7, and the second lifting driving mechanism 404 drives the pressing fixing member 402 downward to clamp the workpiece 7 until the end faces of the rigid cylinder 302 and the pressing fixing member 402 respectively abut against the end faces of the workpiece 7; the elastic compression block 306 and the cylindrical elastic member 403 are respectively compressed to clamp the workpiece 7, and the clamping rod 305 moves outward and presses against the inner wall of the workpiece 7 under the push of the elastic compression block 306; one end of the guide wheel 504 is inserted into the belt mounting groove of the workpiece 7, the end of the guide wheel 504 abuts against the bottom of the belt mounting groove, and the upper side of the guide wheel 504 abuts against the top surface of the belt mounting groove; the driving motor 602 drives the rigid cylindrical member 302 to rotate to drive the workpiece 7 to rotate. During the rotation, the end face runout and side face runout of the workpiece 7 are transmitted outward through the runout transmission rod 503.

[0038] The present invention clamps the workpiece 7 by means of a push assembly and a press assembly, and then the guide wheel 504 of the jumping transmission mechanism 5 contacts the belt installation groove of the workpiece 7. Since the jumping transmission rod 503 of the jumping transmission mechanism 5 is installed by means of a flexible connection assembly 502, the workpiece 7 in the rotating process can fully transmit the end face jumping and side face jumping of its belt installation groove to the outside through the jumping transmission rod 503 under the drive of the driving mechanism. At this time, it is only necessary to detect the end face jumping and side face jumping of the jumping transmission rod 503 by means of a set of dial indicators, thereby greatly improving the convenience of the pulley jumping detection operation.

[0039] In order to prevent excessive mechanical loss to the workpiece 7, the existing push assembly and the pressing assembly mostly use flexible clamping when clamping the workpiece 7. Since the guide wheel 504 will react to the workpiece 7 during the bouncing transmission process with the workpiece 7, the use of flexible clamping will cause the workpiece 7 itself to shake, thereby affecting the bouncing detection accuracy of the workpiece 7. To this end, the present invention makes collaborative improvements to the push assembly and the pressing assembly, so that after the workpiece 7 is clamped, the end faces of the rigid cylinder 302 and the pressing fixing member 402 are respectively abutted against the end faces of the workpiece 7 to form a stroke limit on the workpiece 7 in the longitudinal direction; and the elastic compression block 306 and the cylindrical elastic member 403 are respectively compressed to clamp the workpiece 7; in addition, the clamping rod 305 moves outward under the push of the elastic compression block 306 and presses against the inner wall of the workpiece 7, so that the stroke limit of the workpiece 7 can be formed in the transverse direction. Thereby, the workpiece 7 can be sufficiently clamped and fixed, and without causing excessive mechanical damage to the workpiece 7, the travel of the workpiece 7 can be limited longitudinally and transversely, respectively, to ensure that the workpiece 7 does not shake or deflect during its rotation, thereby ensuring that the end face runout and side runout of the workpiece can be transmitted outwardly with high precision through the runout transmission rod, thereby ensuring the runout detection accuracy.

[0040] The flexible connection assembly 502 includes a group of connection blocks 5021 fixedly connected to the fixed plate 501 and the jumping transmission rod 503. The two sides of the connection block 5021 are supported and connected by corresponding elastic metal plates 5022.

[0041] A group of corresponding gear rods 8 are arranged on one side of the feeding end of a group of pulley transmission belts 2, and the gear rods 8 are driven by corresponding gear rod driving cylinders 9. A corresponding material detection sensor 11 is arranged on the upper part of a group of gear rods 8 through a corresponding support plate 10. A group of corresponding material blocking cylinders 12 are fixedly installed on the frame 1 on the front side of the push assembly, and the piston rod ends of a group of the material blocking cylinders 12 are arranged oppositely and fixedly connected with corresponding buffer blocks 13.

[0042] The first lifting drive mechanism 303 and the second lifting drive mechanism 404 both use lifting drive cylinders. The fixed plate 501 is driven by a fixed plate drive mechanism 14 fixedly mounted on the frame 1, and the fixed plate drive mechanism 14 uses a screw transmission mechanism. The outer ends of the tightening rods 305 are respectively arranged in a spherical shape.

[0043] Embodiment 2

[0044] A pulley runout detection device comprises a runout detection mechanism 15 and a pulley rotation transmission mechanism as described in Example 1, wherein the runout detection mechanism 15 comprises a first dial indicator 1501 for end face runout detection and a second dial indicator 1502 for side face runout detection, and the detection heads of the first dial indicator 1501 and the second dial indicator 1502 are respectively abutted against the upper side and outer side of the runout transmission rod 503.

[0045] A Z-shaped mounting block 16 is fixedly connected to the fixed plate 501 of the pulley rotation transmission mechanism, and the first dial indicator 1501 and the second dial indicator 1502 are fixedly connected to the top surface and the side surface of the Z-shaped mounting block 16 respectively.

[0046] During the detection process, the driving motor 602 drives the rigid cylinder 302 to rotate, so as to drive the workpiece 7 to rotate. During the rotation process, the end face runout and side face runout of the workpiece 7 are transmitted outwards through the guide wheel 504 and the runout transmission rod 503; and then the first dial gauge 1501 and the second dial gauge 1502 are used to respectively detect the runout transmission rod 503, that is, the end face runout and side face runout of the workpiece 7. The overall operation is extremely convenient, and the detection accuracy can meet the design requirements.
