Description

Technical Field

[0001] This utility model relates to the technical field of automotive muffler clamping equipment, specifically a clamping mechanism for automotive mufflers. Background Technology

[0002] Automotive mufflers are components that reduce the noise generated by a vehicle's engine. The muffler's outer shell is generally elliptical in shape. On a production line, the transfer of automotive mufflers is typically achieved through a gripper mechanism and an industrial robot. Currently, each line generally uses a separate gripper mechanism for transfer. Sharing a single gripper mechanism between two different production lines could reduce costs. Furthermore, existing gripper mechanisms for automotive mufflers generally use a single set of grippers, leaving room for improvement in gripping efficiency. Therefore, an improved technology is urgently needed to address this problem in the current technology. Utility Model Content

The first connecting rod 14 is connected to the double claw plate 12. The first inner clamping plate 15 is provided on the inner side of the first connecting rod 14, and the second inner clamping plate 16 is provided on the outer side of the first connecting rod 14.

[0028] Installation method and operating principle: Install cylinder 3 inside connecting seat 2, then install panel 4 on the upper surface of connecting seat 2, and simultaneously install gear 8 in the middle position of panel 4 via bearing. Then connect the bottom end of connecting frame 11 to the piston of cylinder 3. Next, slide the first slide plate 6 with double claw plate 12 to guide rail 5 via slider, and slide the second slide plate 7 with single claw plate 13 to guide rail 5 via slider, and make the first rack 9 of the first slide plate 6 and the second rack 10 of the second slide plate 7 mesh with gear 8. Then fasten the top end of connecting frame 11 to the first slide plate 6 with bolts to complete the assembly of clamping mechanism. At this time, cylinder 3 drives the first slide plate 6 to move along guide rail 5, and through the cooperation of the first rack 9 and gear 8 with the second rack 10, the second slide plate 7 moves in the opposite direction at the same speed along guide rail 5. Two clamping mechanisms are symmetrically mounted on both ends of the base plate 1 via connecting seats 2. Then, the first inner clamping plate 15 is bolted to the inside of the first connecting rod 14, and the outer clamping plate 18 is bolted to the inside of the second connecting rod 17. Countersunk holes are provided in both the first and second connecting rods 14 and 17 to ensure proper bolt engagement. Next, the second inner clamping plate 16 is bolted to the sides of the first connecting rod 14 away from the first inner clamping plate 15, completing the installation. Finally, the base plate 1 is connected to the industrial robot 20, completing the installation. In use, the industrial robot 20 can be installed on two production lines. One size of automotive muffler is matched with the first inner clamping plate 15 and the outer clamping plate 18, while another size of automotive muffler is matched with the second inner clamping plate 16. When the first inner clamping plate 15 and the outer clamping plate 18 of the same clamping mechanism are engaged, the cylinder 3 drives the connecting frame 11 and the first slide plate 6 to move. Through the engagement of the first rack 9 and the gear 8 with the second rack 10, the second slide plate 7 moves in the opposite direction at the same speed along the guide rail 5, thereby realizing the approach and distance of the double claw plate 12 and the single claw plate 13, and thus clamping the car muffler through the inner clamping plate and the outer clamping plate 18. When engaged with the second inner clamping plate 16 of the two clamping mechanisms, the cylinder 3 of each clamping mechanism drives the connecting frame 11 and the first slide plate 6 to move closer to the middle position of the base plate 1, realizing that the double claw plates 12 of the two clamping mechanisms move closer to each other, and thus clamping a car muffler of another size through the second inner clamping plate 16 of each of the two clamping mechanisms. This utility model has a reasonable structure. Two clamping mechanisms are symmetrically arranged on the upper surface of the base plate 1. When the clamping mechanisms cooperate with the double claw plate 12 and the single claw plate 13, they can clamp the car muffler through the first inner clamping plate 15 and the outer clamping plate 18. When the two clamping mechanisms cooperate with the double claw plate 12, they can clamp the car muffler of another size through the two second inner clamping plates 16. The same clamping mechanism can clamp two types of car mufflers at the same time, which greatly reduces the cost and greatly improves the flexibility. Furthermore, by using two clamping mechanisms, when the clamping mechanisms cooperate with the double claw plate 12 and the single claw plate 13 of the main body, they can clamp two car mufflers at the same time, thereby improving production efficiency.
