[0035] A ball 18 is movably embedded in one end of the push rod 17 away from the articulated seat 15, and a spring 19 is fixedly installed at the center of one side of the articulated seat 15 away from the push rod 17. A positioning block 20 is fixedly connected to one end of the spring 19 away from the articulated seat 15, and the positioning block 20 is fixedly connected to the support plate 7 or the positioning plate 13. The spring 19 is used to drive the articulated seat 15 to move.

[0036] Baffle plate 22 is close to the right end of conveyor belt 2 5. Two symmetrically distributed baffle plates 23 are installed on the outer side of conveyor belt 1 4, and baffle plate 3 23 is close to the middle part of conveyor belt 1 4. Both ends of baffle plate 1 21, baffle plate 2 22 and baffle plate 3 23 are provided with beveled edges. The connection mode between ball bearing 18 and baffle plate 1 21, baffle plate 22 and baffle plate 3 23 is rolling contact. Ball bearing 18 is used to reduce the friction resistance between push rod 17 and baffle plate 1 21, baffle plate 22 and baffle plate 3 23.

[0037] Working principle: The left end of the machine base 1 is the loading station, and the right end of the machine base 1 is the unloading station. When the conveyor belt 4 drives the clamping mechanism 1 to move to the loading station, the ball 18 rolls and contacts with the baffle 21 through the bevel. During this process, the two hinge seats 15 on the positioning plate 6 will approach each other, and the hinge seat 15 drives the two support plates 7 away from each other through the oblique connecting rod 16. The personnel place the automobile bearing on the two sleeves 12 at the loading station, and make the inner wall side of the automobile bearing face upward. After the automobile bearing moves to the lower side of the auxiliary roller 36, the personnel The bearing can be released. Under the action of the auxiliary roller 36, the two ends of the automobile bearing can be located on the same straight line. The ball 18 moves away from the baffle plate 21. The two hinge seats 15 on the positioning plate 6 will move away from each other under the drive of the compression force of the spring 19. The two clamping plates 9 are close to each other to clamp and position the bearing. In the process of the clamping mechanism clamping the automobile bearing, the nozzle 2 on the upper side sprays the inner wall of the automobile bearing. When the automobile bearing moves to the dryer 3 on the upper side, the dryer 3 dries the coating on the inner wall of the automobile bearing.

[0038] When the conveyor belt 14 drives the automobile bearing to move to the baffle plate 22 through the clamping mechanism 1, the baffle plate 22 drives the two hinge seats 15 on the positioning plate 6 to approach each other through the push rod 17, that is, the two clamping plates 9 move away from each other to release the automobile bearing, so that the automobile bearing falls on the positioning plate 2 13 on the conveyor belt 25, and the outer wall of the automobile bearing falling on the positioning plate 2 13 faces upward, and the conveyor belt 25 drives the positioning plate 2 13 to move, so that the push rod 17 on the positioning plate 2 13 is separated from the baffle plate 3 23, and the two clamping strips 14 will clamp the automobile bearing under the drive of the compression elastic force of the spring 19. When the clamping mechanism 2 When the automobile bearing is clamped and moved to the nozzle 2 located on the lower side, the nozzle 2 sprays the outer wall of the automobile bearing. After spraying, the dryer 3 located on the lower side dries the coating on the outer wall of the automobile bearing. Finally, the clamping mechanism 2 drives the bearing to move to the unloading station of the machine base 1. The baffle 3 23 drives the two clamping strips 14 away from each other through the adjustment component, and the clamping of the automobile bearing is released. The personnel can remove the automobile bearing. The device can not only spray the inner and outer walls of the automobile bearing, but is also suitable for different models of automobile bearings, and can spray automobile bearings in batches. It has a wide range of uses.

[0039] Example 2: Please refer to Figure 2 , Figure 3The present embodiment further explains the first embodiment, the limit assembly includes a bent connecting rod 24 fixedly mounted at the center of the lower end of the sleeve 12, the end of the bent connecting rod 24 away from the sleeve 12 is movably sleeved with a roller 25, two symmetrically distributed arc guide rails 27 are fixedly mounted on the inner side of the machine base 1, and the connection between the roller 25 and the inner wall of the arc guide rail 27 is rolling contact, an inclined portion 28 is provided at the left end of the arc guide rail 27, and the connection between the roller 25 and the inclined portion 28 is rolling contact, and a counterweight block 26 is fixedly mounted on the outer side of the splint 9, and the counterweight block 26 is used to increase the weight of the splint 9.

[0040] In this embodiment: when the clamping mechanism 1 clamps the automobile bearing and moves it to the lower side of the conveyor belt 1 4, before the ball 18 on the positioning plate 1 6 contacts the baffle plate 2 22, the roller 25 will first break away from the arc guide rail 27. After the roller 25 breaks away from the arc guide rail 27, the two clamping plates 9 and the automobile bearing will move downward under the action of the gravity of the counterweight block 26, so that the automobile bearing falls on the positioning plate 2 13 on the clamping mechanism 2. Since the two clamping plates 9 still maintain the clamping state of the automobile bearing at this time, the automobile bearing that falls on the positioning plate 2 13 can be exactly located at the center of the positioning plate 2 13, thereby facilitating the stable handover of the automobile bearing by the clamping mechanism 1 and the clamping mechanism 2. When the clamping mechanism 2 clamps the automobile bearing and the ball 18 on the clamping mechanism 1 abuts against the baffle plate 22, the roller 25 will roll along the inclined portion 28 of the arc guide rail 27, so that the clamping plate 9 moves back and resets, thereby preventing the clamping mechanism 1 from affecting the normal movement of the bearing on the clamping mechanism 2.

[0041] Example 3: Please refer to Figure 5 , Figure 6 This embodiment further explains the second embodiment. The deceleration assembly includes a tooth plate 29 fixedly embedded on the outer side of the clamping plate 9. A rubber ball 34 is movably abutted on the outer side of the tooth plate 29. A connecting rod 31 is fixedly embedded on the outer side of the rubber ball 34. The connection between the rubber ball 34 and the tooth plate 29 is a sliding contact. A hinge seat 2 30 is installed on the outer side of the connecting rod 31, and the connecting rod 31 is rotatably connected to the hinge seat 2 30 through a positioning shaft 32.

[0042] The connection between the articulated seat 2 30 and the support plate 7 is a fixed connection. Two symmetrically distributed coil springs 33 are fixedly sleeved on the outer side of the positioning shaft 32, and the outer ends of the coil springs 33 are fixedly connected to the articulated seat 2 30. A stopper 35 is movably abutted on the upper side of the connecting rod 31, and the connection between the stopper 35 and the articulated seat 2 30 is a fixed connection. The stopper 35 is used to limit the rotation direction of the connecting rod 31.

[0043] In this embodiment: during the process of the splint 9 moving out from the inside of the support plate 7, the connecting rod 31 is blocked by the stopper 35, so the connecting rod 31 and the rubber ball 34 cannot rotate at this time, so the rubber ball 34 will directly contact and rub with the tooth plate 29, increasing the resistance of the splint 9 moving out of the support plate 7, thereby slowing down the speed of the splint 9 moving out of the support plate 7, and effectively preventing the automobile bearing from hitting the positioning plate 2 13 under the action of the gravity of the counterweight block 26. When the inclined portion 28 drives the splint 9 to move back and reset through the roller 25, the rubber ball 34 can rotate at this time, so it will not affect the moving back and resetting of the splint 9.
