Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a special-shaped clamping tool, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a special-shaped clamping tool, including a base, the top of the base is slidably connected to an arc clamp, the side of the arc clamp is fixedly connected to a movable plate, and the top of the base is provided with a conversion component;

[0005] The conversion assembly includes hydraulic chamber 1 and hydraulic chamber 2, wherein the piston at one end of the hydraulic chamber 1 is slidably connected to the joystick 1, and the piston at the other end of the hydraulic chamber 1 is slidably connected to the gear rod, the top of the movable plate is rotatably connected to the gear, the inner wall of the movable plate is slidably connected to the arc-shaped baffle plate, the piston at one end of the hydraulic chamber 2 is slidably connected to the joystick 2, and the piston at the other end of the hydraulic chamber 2 is slidably connected to the push rod, and the side of the push rod is fixedly connected to the vertical support plate.

[0006] Preferably, the gear is located at a side position of the gear rod, and the gear is in meshing state with the gear rod, so that when the gear rod moves, the gear can rotate accordingly.

[0007] Preferably, teeth are provided on one side of the arc-shaped baffle plate close to the gear, and the arc-shaped baffle plate is meshed with the gear through the teeth, so that when the gear rotates, the arc-shaped baffle plate can rotate accordingly.

[0008] Preferably, the vertical support plate is located on the side of the arc-shaped baffle.

[0009] Preferably, a clamping assembly is provided on the top of the base;

[0010] The clamping assembly comprises a fixing groove, the top of the movable plate is fixedly connected with a fixing plate, and the side of the fixing plate is connected with a clamping rod via a spring.

[0011] Preferably, the cross-sectional shape of the fixing groove is the same as the cross-sectional shape of the clamping rod, so that the clamping rod is placed in the fixing groove to limit the movement of the first and second operating rods.

[0012] The utility model provides a special-shaped clamping tool, which has the following beneficial effects:

[0013] (1) The special-shaped clamping tool can clamp the arc-shaped workpiece by pushing the movable plate to drive the arc-shaped clamp to move. When the vertical workpiece needs to be clamped, the vertical workpiece can be clamped by moving the joystick 1 upwards in conjunction with the hydraulic bin 1, the gear rod, the gear, the arc-shaped baffle plate, the joystick 2, the hydraulic bin 2, the push rod, and the vertical support plate. This allows the device to clamp both the arc-shaped workpiece and the vertical workpiece, making it easier to use.

[0014] (2) Before the joystick 1 and the joystick 2 need to be moved, the clamping rod needs to be moved toward the side of the fixed plate so that the clamping rod squeezes the spring and moves. At this time, the clamping rod moves out of the fixed groove, so that the joystick 1 and the joystick 2 are no longer restricted. In this way, the joystick 1 and the joystick 2 are difficult to be moved without moving the joystick 1 and the joystick 2, thereby reducing the possibility of accidentally touching the joystick 1 and the joystick 2.

The piston at one end of the hydraulic chamber 1 4 is slidably connected to an operating rod 1 6, and the piston at the other end of the hydraulic chamber 1 4 is slidably connected to a gear rod 7. When the vertical workpiece needs to be clamped, the operating rod 6 is moved upward to cooperate with the hydraulic chamber 1 4 slidably connected to the piston of the operating rod 6, so that the pressure in the hydraulic chamber 4 is reduced, driving the gear rod 7 slidably connected to the piston of the hydraulic chamber 4 to move. The top of the movable plate 3 is rotatably connected to a gear 8, and the gear 8 is located at the side of the gear rod 7. The gear 8 is meshed with the gear rod 7. The inner wall of the movable plate 3 is slidably connected to an arc-shaped baffle plate 9. The arc-shaped baffle plate 9 is provided with teeth on the side close to the gear 8. The arc-shaped baffle plate 9 is meshed with the gear 8 through the teeth. When the gear rod 7 moves, the gear rod 7 drives the gear 8 meshing therewith to rotate. The gear 8 drives the arc-shaped baffle 9 meshing with it to rotate, and the piston at one end of the hydraulic warehouse 25 is slidably connected to the joystick 2 10, and the piston at the other end of the hydraulic warehouse 25 is slidably connected to the push rod 11, and the side of the push rod 11 is fixedly connected to the vertical support plate 12, and the vertical support plate 12 is located on the side of the arc-shaped baffle 9.
