[0021] When the present invention is in use: the base 1 is placed in a position, and then the whole is in an unclamped state for use. At this time, the required workpiece can be taken out and placed on the upper end of the outer wall of the pad 3, and the pad 3 is in the middle position, and the workpiece is used in the middle position as much as possible. After the workpiece is placed, the four groups of buckles 9 can be engaged first, and the opening on the front side of the buckle 9 can be pressed to make the front side of the buckle 9 in an open state, so that the middle of its inner part can be matched with the middle of the outer wall of the clamping ring 8, and the buckle 9 can be made to correspond to the use position of the clamp 7. After the four groups of buckles 9 are installed in the horizontal and vertical directions, the hydraulic rod 12 on the upper side of the baffle 2 can be started to make it move, and the lower side can be pushed out to make it vertical.

When the sleeve 15 is moved in the vertical direction, the pressure plate 22 is driven to move in the vertical direction at the same time. When the pressure plate 22 is moved, the pressure block 29 is driven to continuously approach the workpiece. At this time, the bottom of the pressure block 29 will first contact the outer wall surface of the workpiece, and the telescopic rod 28 and the spring 26 are adapted for use, so that the pressure block 29 is in contact with the outer wall surface of the workpiece. At the same time, when the pressure block 29 is clamped, the telescopic rod 28 and the damping block 27 are driven to squeeze the spring 26 inside the sleeve rod 24, so that the spring 26 generates a restoring force after being squeezed and pushes out the telescopic rod 28, and the workpiece is clamped between the pressure block 29 and the pad 3, so as to facilitate the vertical position clamping and stabilization of the workpiece. , so that the workpiece in the middle position will not move up and down, and after the clamping effect is achieved, the use of the hydraulic rod 12 can be ended to keep it in position, and then the electric push rod 13 can be started to push the motor 14 so that the motor 14 is at the lower side for use. Because the output end of the motor 14 is connected to the movable rod 17, the movable rod 17 can be driven to move vertically first, so that the gear 18 and the tooth 19 on the outer wall are staggered. At this time, the motor 14 is started by remote control to drive the movable rod 17 to rotate, so that it drives the sleeve 20 to rotate and reel the pull rope 10, thereby reducing the length of the pull rope 10 on the outer wall, and at the same time pulling the buckle 9, so that the buckle 9 simultaneously changes the position of the splint 7, and the four groups of splints can be 7 can be used to clamp the four corners of the outer wall of the workpiece stably, and the two groups of buckles 9 are used correspondingly with the two groups of clamps 7. At this time, the clamp 7 is moved horizontally on the outer wall surface of the fixed rod 5 through the sleeve block 6, so that the workpiece placed in the middle can be clamped at the four corners, and the clamp 7 will be pulled by the pull rope 10, and after the clamp 7 is moved, it can contact the outer wall surface of the workpiece. After clamping, the electric push rod 13 can be used to make a small change to the motor 14, so that the motor 14 drives the movable rod 17 to move vertically, and the gear 18 and the teeth 19 are meshed with each other, thereby increasing stability, making it less likely to slip, and reducing the self-locking pressure of the motor 14. At this time, the workpiece is stably clamped between the four corners and the upper and lower parts.It can be adapted to workpieces of different sizes. At the same time, when the pull rope 10 is rotated and tightened, if there is some looseness, it can be tightened by rotation to keep it stable.
[0022] Working principle: the base 1 is placed and the whole is in an unclamped state before use. The required workpiece is taken out and placed on the upper end of the outer wall of the pad 3. The pad 3 is in the middle position, so that the workpiece is also in the middle position. After the workpiece is placed, the four sets of buckles 9 can be engaged first, and the opening on the front side of the buckle 9 is pressed to make the front side in an open state, and the middle of the inner part is matched with the middle of the outer wall of the clamping ring 8. The buckle 9 corresponds to the use position of the clamp 7. After the buckle 9 is in the horizontal and vertical corresponding installation, the hydraulic rod 12 on the upper side of the baffle 2 is started to move it, and the lower side is pushed out to make it move vertically. When the collar 15 moves vertically, it drives the pressure plate 22 to move vertically. When the pressure plate 22 moves, it drives the pressure block 29 to approach the workpiece. The bottom of the pressure block 29 first contacts the outer wall surface of the workpiece, so that the four groups of pressure blocks 29 are used under different degrees of extrusion. The four groups of pressure blocks 29 are all in contact with the outer wall surface of the workpiece, and when the pressure blocks 29 are continuously clamped, they will drive the damping block 27 to squeeze the spring 26 inside the sleeve rod 24 through the telescopic rod 28, so that the spring 26 generates a restorative force after being squeezed and pushes out the telescopic rod 28, so as to effectively clamp the workpiece vertically and stabilize it. After the clamping effect is achieved, the use of the hydraulic rod 12 is ended to keep it in position, and then the electric push rod 13 is started to push the motor 14 so that the motor 14 is at the lower side for use, and the output end of the motor 14 is connected to the movable rod 17, driving the movable rod 17 to move vertically, so that the gear 18 and the tooth 19 on the outer wall are staggered. At this time, the motor 14 is started by remote control to drive the movable rod 17 to rotate, and the sleeve 20 is driven to rotate and reel the pull rope 10, thereby reducing the length of the pull rope 10 on the outer wall, and at the same time, the buckle 9 is pulled, so that the buckle 9 simultaneously changes the position of the splint 7, and the splint 7 is all at the same time. The outer wall of the workpiece can be clamped and stabilized at the four corners, and the clamping plate 7 is moved laterally on the outer wall surface of the fixed rod 5 through the sleeve block 6. After clamping, the motor 14 is slightly changed through the electric push rod 13. The motor 14 drives the movable rod 17 to move vertically, so that the gear 18 and the teeth 19 are engaged with each other, which increases stability and is not easy to slip, and reduces the self-locking pressure of the motor 14. At this time, the workpiece is stably clamped between the four corners and the top and bottom, and can be adapted to workpieces of different sizes. At the same time, by rotating and tightening the pull rope 10, when there is partial looseness, it can also be tightened by rotation to maintain stability.
