[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a clamping assembly for detecting an automobile pulley, comprising a frame 1, wherein walking mechanisms 2 are provided on both sides of the bottom of the frame 1, and the walking mechanisms 2 are at least used to drive the frame 1 to walk on the truss guide rail; a lifter 3 is provided in the middle part below the frame 1, and the lifter 3 is at least used to move up and down; a transposition tooling 4 is provided below the lifter 3, and a rotary beam 5 is provided at the bottom of the transposition tooling 4, and the transposition tooling 4 is at least used to rotate and reposition the rotary beam 5, and the lifter 3 drives the transposition tooling 4 and the rotary beam 5 to move synchronously; a power module 6 is provided above both ends of the rotary beam 5, and a clamping mechanism 7 is provided below both ends of the rotary beam 5, the power module 6 is connected to the clamping mechanism 7 by transmission, the power module 6 is at least used to drive the clamping mechanism 7 to move, and the clamping mechanism 7 is at least used to fix and release the automobile pulley.

[0037] In this embodiment, the frame 1 is made of steel structure to ensure its support strength;

[0038] Specifically, weight-reducing holes 11 are provided on both sides of the rack 1. The weight-reducing holes 11 are rectangular structures, which can reduce the weight of the rack 1, making the component lightweight. Several through holes 12 are provided on the outer wall of the top of the rack 1. The guide rod 36 described below can be inserted into the through hole 12 to limit the guide rod 36.

[0039] In this embodiment, Figure 3 As shown, a walking mechanism 2 is provided on both sides of the bottom of the frame 1, and the walking mechanism 2 is at least used to drive the frame 1 to move on the truss guide rail;

[0040] Specifically, the walking mechanism 2 includes a walking motor 21, which is fixedly mounted on the outer wall of the bottom of the frame 1. Synchronously rotating transmission shafts 22 are provided at both ends of the walking motor 21, and transmission wheels 23 are provided at the ends of the transmission shafts 22. Belts 24 are provided on the transmission wheels 23. Bearing seats 26 are provided on the outer walls of both sides of the bottom of the frame 1, and a walking gear 25 is provided on the bearing seats 26 through a rotating shaft. One side of the walking gear 25 is connected to the belt 24 through the transmission wheel 23. When the walking motor 21 is started, the transmission wheel 23 is driven to rotate through the transmission shaft 22, and the traveling gear 25 is driven to rotate through the belt 24.

[0041] Specifically, the traveling gears 25 on both sides of the frame 1 are symmetrically distributed, and at least two traveling gears 25 are provided on each side of the frame 1. The traveling gears 25 are engaged with the racks on the truss guide rails. The traveling gears 25 can move on the racks on the truss guide rails, thereby ensuring the stability and accuracy of the movement of the traveling mechanism 2.

[0042] In this embodiment, Figure 5 and 6 As shown, a lifter 3 is provided at the middle portion below the frame 1, and the lifter 3 is used for at least lifting and moving up and down;

[0043] Specifically, the lifter 3 includes a mounting base 31 fixed to the outer wall of the bottom of the frame 1, a plurality of guide holes 32 are provided on the top of the mounting base 31, a lifting motor 33 is provided on the outer wall of the bottom of the mounting base 31, and a lifting rod 34 is provided at the bottom of the lifting motor 33, a connecting support rod 37 is movably installed at the bottom end of the lifting rod 34, a guide sleeve 35 is provided at both ends of the connecting support rod 37, and a plurality of guide rods 36 slidably inserted into the inside of the guide hole 32 are fixedly provided on the outer wall of the top of the guide sleeve 35. When the lifting motor 33 is started, the lifting motor 33 drives the lifting rod 34 to move up and down. The lifting rod 34 can be a threaded screw. The connection between the lifting motor 33 and the threaded screw drives the threaded screw to rotate, so that the lifting rod can move up and down inside the lifting motor 33. Since the bottom end of the lifting rod 34 is movably connected to the connecting support rod 37, the lifting rod 34 can be used to drive the guide sleeve 35 to move up and down.

[0044] Specifically, the internal dimensions of the guide sleeve 35 are larger than the external dimensions of the lifting motor 33, and the guide sleeve 35 is slidably sleeved on the outside of the lifting motor 33. When the guide sleeve 35 moves up and down, the guide sleeve 35 slides on the outside of the lifting motor 33 to avoid motion interference. The structural design is reasonable. When the guide sleeve 35 is lifted or lowered, the guide rod 36 slides inside the guide hole 32 and the through hole 12.

[0045] In this embodiment, Figure 5 and 6 As shown, a transposition tooling 4 is provided below the lifter 3, and a rotary beam 5 is provided at the bottom of the transposition tooling 4. The transposition tooling 4 is at least used to rotate and reposition the rotary beam 5. The lifter 3 drives the transposition tooling 4 and the rotary beam 5 to move synchronously up and down.

[0046] Specifically, the reversing tool 4 includes a reversing motor 41. A mounting plate 43 is mounted on the rotating shaft at the bottom of the reversing motor 41. The mounting plate 43 is fixed to the outer wall of the bottom of the rotating beam 5. A positioning assembly 42 is provided between the reversing motor 41 and the rotating beam 5. When the reversing motor 41 is started, it can drive the rotating beam 5 to rotate from 0 to 180 degrees. At the same time, the reversing motor 41 is in forward and reverse motion.

[0047] Specifically, such as Figure 4 As shown, the positioning assembly 42 is composed of a fixed plate 421 fixed on the outer wall of one side of the reversing motor 41 and a movable plate 422 fixedly installed on the outer wall of the top of the rotary beam 5. Since the reversing motor 41 is a relatively fixed structure, when the reversing motor 41 is used to drive the rotary beam 5 to rotate, it can drive the movable plate 422 to move with the rotary beam 5. The contact between the movable plate 422 and the fixed plate 421 can achieve the limiting of the rotation of the rotary beam 5. The positioning assembly 42 here can also be set on both sides of the position change tooling 4 at the same time, which can package the accuracy of the 0-180 degree rotation of the rotary beam.

[0048] In this embodiment, Figure 7and 8 As shown, power modules 6 are provided above both ends of the rotary beam 5, and the power modules 6 are at least used to drive the clamping mechanism 7 to operate;

[0049] Specifically, the power module 6 includes a forward and reverse motor 61 fixedly mounted on the top outer wall of the rotating beam 5, and a connecting shaft 62 is provided at the bottom of the forward and reverse motor 61, which passes through the bottom of the rotating beam 5. A turntable 63 is provided at the bottom end of the connecting shaft 62, and a plurality of guide channels 64 are provided on the turntable 63. When the forward and reverse motor 61 is started, the turntable 63 is driven to rotate forward and reverse through the connecting shaft 62. For example, when the turntable 63 rotates forward, the trajectories of several clamps 76 can be enlarged at the same time. When the turntable 63 rotates reversely, the trajectories of the clamps 76 can be reduced at the same time.

[0050] In this embodiment, Figure 7 and 8 As shown, a clamping mechanism 7 is provided below both ends of the rotary beam 5, and the power module 6 is transmission-connected to the clamping mechanism 7, which is at least used for fixing, clamping and releasing the automobile pulley;

[0051] Specifically, the clamping mechanism 7 includes a plurality of legs 72 fixed to the outer wall of the bottom of the rotating beam 5, and a bracket 71 is welded to the outer wall of the bottom of the leg 72, a slide groove 73 is provided on the bracket 71, and a slide saddle 74 is slidably inserted in the inner part of the slide groove 73, and a follower pin 75 inserted into the guide channel 64 is fixedly installed on the top of the slide saddle 74. A clamping claw 76 is fixedly installed on the outer wall of the bottom of the slide saddle 74, and a pad 77 is provided on the outer wall of one side of the clamping claw 76. The number of the clamping claws 76 can preferably be three, and the corresponding slide saddle 74 is also three. The pad 77 can be made of soft rubber material, which can play a protective role when the clamping claw 76 is used to clamp the outer part of the automobile pulley.

[0052] Start the forward and reverse motor 61 to drive the turntable 63 to rotate. Since the follower pin 75 is inserted into the inside of the guide channel 64, the turntable 63 will drive the follower pin 75 to move inside the guide channel 64, so that several saddles 74 can slide inside the slide groove 73, so that several clamps 76 move centripetally at the same time, and the clamps 76 are used to achieve stable clamping of the automobile pulley.

[0053] Working principle: The utility model can be designed with multiple inspection stations, such as appearance inspection station, dynamic balance inspection station, sealing inspection station, etc., and a conveyor is set between the above inspection stations;

[0054] Workers can place the automobile pulley to be tested on the conveyor and use the conveyor to transport the automobile pulley;

[0055] The frame 1 is driven to move on the truss guide rail by the walking mechanism 2, so that the clamping mechanism 7 moves. When the clamping mechanism 7 moves above the automobile pulley on the conveyor, the lifter 3 is started to drive the clamping mechanism 7 to descend. Driven by the power module 6, the clamping mechanism 7 can achieve fixed clamping of the automobile pulley, and the lifter 3 is started to drive the clamping mechanism 7 and the automobile pulley to rise.

[0056] Next, the traveling mechanism 2 is started again, so that the traveling mechanism 2 drives the frame 1 to move to one of the above-mentioned inspection stations, and the rotary beam 5 is rotated by the position change tool 4, so that the automobile pulley on the clamping mechanism 7 is sent to the inspection station, and the lifter 3 is started again to move downward, and the clamping mechanism 7 is released by the power module 6, so that the automobile pulley is stably placed on the inspection station;

[0057] In this way, by repeating the above actions, the automobile pulley can be switched between different workstations, and a more automated detection operation of the automobile pulley can be achieved, which greatly improves the efficiency of automobile pulley detection.

[0058] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
