Limiting block 3B and limiting groove 2A are both V-shaped structures. The V-shaped structure makes the limiting block 3B firmly clamped in the limiting groove 2A, so as to avoid the rotation of the rotating table 2 during processing.

[0030] Limiting groove 2A can be processed according to the required rotation angle of the user to adapt to different angle requirements. In this embodiment, rotating table 2 is composed of shaft 2B and cover plate, and support pad is arranged between cover plate and shaft 2B, and the support pad is arranged at one end of bridge plate 1. The cover plate and the shaft 2B press the support pad tightly through bolts, so that the rotating table 2 can only rotate in place on the bridge plate 1 through the first bearing 1A. Limiting groove 2A is symmetrically arranged around the shaft 2B, so that the rotating table 2 can be adjusted by 90 degrees at a time. Moreover, the first driving part 3A is provided with two, and the first driving part 3A is symmetrically arranged on both sides of the shaft 2B, so that the two sides of the shaft 2B are provided with limiting blocks 3B matched with the limiting groove 2A.

[0031] Moreover, the lower end of the bridge plate 1 is provided with a mounting seat 5 for fixing the first driving part 3A, and the mounting seat 5 is provided with a sliding groove 5A matched with the limiting block 3B.

The output end of the second driving part 8A is provided with a fixed block 81A matched with the fixed grooves 81B. In addition, the fixed block 81A and the fixed grooves 81B are in the form of teeth. One end of the base 6 is provided with a gas connection seat 10 for connecting with an external gas source.

In this way, fine control of the rotation angle of the bridge plate 1 can be realized, so as to meet different operation requirements. Users can also replace the rotating disc 8B with different adjustment angles according to the use requirements, so as to realize more flexible rotation angle adjustment.

[0034] In addition, one side of the rotating disc 8B is provided with a detachable limiting block 82B. When the bridge plate 1 needs to be fixed during transportation or placement in a warehouse, the rotating disc 8B can be clamped by the limiting block 82B, so as to avoid unnecessary rotation of the bridge plate 1 due to vibration or accidental collision during transportation.

The gear shift plate 9A is installed on the side of the rotary seat 6B near the second swing cylinder 7.

[0038] like Figure 7 As shown, the gear shift plate 9A is provided with a gear shift groove, which has an inner groove 91A and an outer groove 92A. Both the inner groove 91A and the outer groove 92A have an included angle of 90 degrees. The first drive element 91B cooperates with the inner groove 91A through a pin 9C, and the second drive element 92B and the third drive element 93B cooperate with the outer groove 92A through pins 9C, allowing for fixed angle restrictions of 90 degrees, 180 degrees, and 270 degrees. When a 90-degree rotation is required, the gear shift groove is restricted by the pins 9C on the first drive element 91B and the second drive element 92B, while the pins 9C on the third drive element 93B and the fourth drive element 94B are retracted to avoid affecting the rotation of the bridge plate 1. When a 180-degree or 270-degree angle rotation is required, the pins 9C on the first, second, and fourth drive elements 94B are retracted, and the gear shift groove is restricted by the pin 9C on the third drive element 93B. Furthermore, when rotating 180 degrees, adjustment must be completed by rotating in the opposite direction.

[0039] The gear shift plate 9A is also provided with three tapered holes 93A that cooperate with the fourth drive element 94B. The tapered holes 93A are arranged around the gear shift plate, forming an included angle of 120 degrees between them. In use, the pin 9C on the output end of the fourth drive element 94B can be pushed to cooperate with the tapered holes 93A to lock the tilt angle of the bridge plate 1.

[0040] The arrangement of the first drive element 91B, the second drive element 92B, the third drive element 93B, and the fourth drive element 94B allows the user to quickly adjust the bridge plate 1 to the commonly used tilt angle during operation, thereby improving work efficiency. When using the third drive element 9B, the fixing block 81A on the second drive element 8A must be retracted to avoid affecting the rotation of the bridge plate 1. Similarly, when using the second drive element 8A, the pins 9C on the third drive element 9B must be fully retracted. Furthermore, the included angle between the inner groove 91A and the outer groove 92A can be 30 degrees or 45 degrees. In actual use, different angled stop plates 9A can be replaced according to different requirements to adapt to different rotation angle needs.

[0041] In the embodiment, the first driving member 3A, the second driving member 8A and the third driving member 9B are all air cylinders, which makes the whole adjusting process more stable and accurate. Moreover, the air cylinders have fast response speed, so that the angle adjustment can be quickly completed, thereby improving the operation efficiency and reducing the manufacturing cost.
