[0034] The positioning group 111 and the pressing group 121 are correspondingly arranged in the horizontal direction.

[0035] By arranging a four-axis turntable 11 on one side of the base plate 1 and a tail stock 12 on the other side, the tail stock 12 can move a certain distance in the horizontal direction on the base plate 1, a positioning group 111 is arranged on the four-axis turntable 11, and a clamping group 121 is arranged on the tail stock 12, the shell is fixedly placed on the positioning group 111, and the positioning group 111 and the clamping group 121 are correspondingly arranged in the horizontal direction, that is, the central axis of the positioning group 111 and the clamping group 121 are on the same straight line, the four-axis turntable 11 can control the adjustment of the positioning group 111 in any position and angle in the three-dimensional space, so that the shell is fixed more firmly, and then the tail stock 12 drives the clamping group 121 to clamp the shell, the positioning group 111 limits the movement of the shell in the vertical direction, and the clamping group 121 limits the movement of the shell in the horizontal direction, the shell is clamped firmly, and will not interfere with the side of the shell, thereby improving the versatility of the clamping device, the positioning group 111 can adapt to a variety of shell sizes, has strong flexibility, accurate positioning, and improves the stability of shell fixation.

[0036] In this embodiment, the pressing group 121 includes a pressing plate 1211 and a cylinder 1212 . The cylinder 1212 pushes the pressing plate 1211 to move in a horizontal direction via a first connecting shaft 1213 .

[0037] The clamping group 121 includes a pressing plate 1211 and a cylinder 1212. The cylinder 1212 pushes the first connecting shaft 1213. The first connecting shaft 1213 pushes the pressing plate 1211 to move in a horizontal direction. The pressing plate 1211 contacts the shell surface and applies a certain pressure to clamp the shell, thereby improving the clamping reliability of the clamping device.

[0038] In this embodiment, the positioning group 111 includes a positioning plate 1111 and a cylinder 1112 . The cylinder 1112 pushes the positioning plate 1111 to move in a horizontal direction via a second connecting shaft 1113 .

[0039] The positioning group 111 includes a positioning plate 1111 and a cylinder 1112. The cylinder 1112 pushes the second connecting shaft 1113. The second connecting shaft 1113 pushes the positioning plate 1111 to move horizontally. When it moves to a predetermined position, the shell is placed, making it more convenient to fix the shell on the positioning plate 1111 and increasing the stability of the shell fixation.

[0040] In this embodiment, a bevel structure 11111 is provided inside the positioning plate 1111, and the bevel structure 11111 includes a pull rod 111112 and a bevel block 111111;

When the shell is placed on the positioning plate 1111, the oblique wedge structure 11111 moves a certain distance into the shell along the horizontal direction. During the movement, the bevel block 111111 will be stuck in the inner hole formed by the shell positioning. At this time, the second connecting shaft 1113 drives the pull rod 111112 to move toward the direction of the cylinder 1212, applying downward pressure to the bevel block 111111, so that the bevel block 111111 is in closer contact with the inner hole, thereby increasing the stability of the clamping device, and the bottom contact portion is arranged to be arc-shaped, thereby reducing the damage of the bevel block 111111 to the inner hole of the shell.

[0044] By arranging the guide rod 12111 on the pressing plate 1211, the guide rod 12111 plays a guiding role, supports the movement of the pressing plate 1211, and ensures the stability of its movement.

[0045] In this embodiment, a sensor 13 is fixedly disposed on the base plate 1, and a sensor plate 122 is also disposed on the tailstock 12;

[0046] When the pressing group 121 approaches the housing, the sensing plate 122 triggers the sensor 13 .

[0047] The base plate 1 is also fixed with a sensor 13, and the sensor plate 122 set on the tailstock 12 will trigger the sensor 13. When the clamping group 121 presses the shell surface, the sensor 13 is triggered, indicating that the clamping device is clamped in place, and the machining center starts to process the shell, thereby improving the machining quality of the shell.

[0048] In this embodiment, a floating positioning pin 12112 is provided in the pressing plate 1211 .

[0049] By setting a floating positioning pin 12112 in the pressure plate 1211 for positioning, the stability of the position of the pressure plate 1211 is maintained, the movement or swing of the position of the pressure plate 1211 is prevented, the impact of the pressure plate 1211 when pressing the shell is reduced, and the processing efficiency is improved.

[0050] In this embodiment, the travel and angle of the tailstock 12 are provided with inductive error-proofing detection.

[0051] By detecting the stroke and angle of the tailstock 12 through induction error prevention, it is ensured that there is no error in the clamping operation of the tailstock 12. If there is a problem, it can be adjusted in time to improve production efficiency.
