For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Please see Figures 1 to 3 This embodiment shows a circuit breaker pole transfer fixture, including a mounting bracket 1, a clamping mechanism 2, a flipping mechanism 3, a floating mechanism 4, and a control handle 5.

[0024] See also Figure 4 and Figure 5 The clamping mechanism 2 includes a first clamping cylinder 21, a first gripper 22, a second clamping cylinder 23, and a second gripper 24. The piston rod of the first clamping cylinder 21 is fixedly connected to the first gripper 22, and the piston rod of the second clamping cylinder 23 is fixedly connected to the second gripper 24. When the first clamping cylinder 21 and the second clamping cylinder 22 are working, they can drive the first gripper 22 and the second gripper 24 to move towards or away from each other to clamp or release the circuit breaker pole.

[0025] Specifically, the clamping mechanism 2 also includes a clamping component mounting base 25, a cylinder connecting column 26, a first sliding sleeve 27, a second sliding sleeve 28, and a sliding rod 29.

[0026] The cylinder connecting column 26 is fixed at the center below the clamping assembly mounting base 25. The first clamping cylinder 21 and the second clamping cylinder 22 are located on opposite sides below the clamping assembly mounting base 25. The piston rod of the first clamping cylinder 21 is fixedly connected to one side of the cylinder connecting column 26, and the piston rod of the second clamping cylinder 23 is fixedly connected to the other side of the cylinder connecting column 26. The first clamping cylinder 21 is fixedly connected to the first gripper 22, and the second clamping cylinder 23 is fixedly connected to the second gripper 24. When the first clamping cylinder 21 and the second clamping cylinder 22 are working, the cylinder connecting column 26 is stationary, while the first clamping cylinder 21 and the second clamping cylinder 22 move towards or away from the first gripper 22 and the second gripper 24, respectively, thereby clamping or releasing the circuit breaker pole. Through the above design, not only is the clamping function of the pole achieved, but it can also be applied to poles of various diameters.

[0027] To improve the stability of the first gripper 22 and the second gripper 24 during movement, this embodiment provides a guide structure. Specifically, a slide rod 29 is fixedly installed below the clamping assembly mounting base 25, with its length direction parallel to the movement direction of the first gripper 22 and the second gripper 24. The first slide sleeve 27 is fixedly connected to the first gripper 22, and the second slide sleeve 28 is fixedly connected to the second gripper 24. The first slide sleeve 27 and the second slide sleeve 28 are respectively slidably sleeved on both ends of the slide rod 29. When the first gripper 22 moves, it drives the first slide sleeve 27 to slide along the slide rod 29, and when the second gripper 24 moves, it drives the second slide sleeve 28 to slide along the slide rod 29.

[0028] Furthermore, the inner side of the first gripper 22 and the inner side of the second gripper 24 are provided with elastic pads 2a, which avoids hard contact between the gripper and the electrode post and can protect the electrode post. At the same time, the elastic pads 2a undergo elastic deformation after contacting the electrode post, which can better adapt to the outer contour of the electrode post and increase the contact area, thereby clamping the electrode post more firmly and preventing the electrode post from falling out accidentally.

[0029] To achieve the flipping of the pole piece, this embodiment includes a flipping mechanism 3. To make the flipping principle clearer, this embodiment provides an example of the specific structure of the flipping mechanism 3. It should be noted that the following description is for illustrative purposes only and is not intended to limit the specific structure of the flipping mechanism 3 of this application: The flipping mechanism 3 includes a flipping cylinder 31 and a flipping arm 32. The flipping cylinder 31 is fixed on the mounting bracket 1. The piston rod of the flipping cylinder 31 is hinged to the top of the flipping arm 32. The bottom of the flipping arm 32 has a connecting plate 33. The clamping mechanism 2 is connected to the connecting plate 33 by a hinge, so that the clamping mechanism 2 can flip relative to the connecting plate. The flipping angle of the flipping cylinder 31 can be controlled by setting limit blocking measures or by control software. In this embodiment, after the flipping cylinder 31 drives the clamping mechanism 2 to flip 90 degrees, it stops working. After the pole piece is assembled, it flips 90 degrees in the opposite direction to reset, in preparation for flipping the next pole piece.

[0030] To achieve a slight angular deviation of the workpiece (i.e., the horizontal tilt angle of the workpiece), this embodiment adds a floating mechanism 4. The floating mechanism 4 includes two sets of adjustment components located on both sides of the hinge. Each set of adjustment components includes an adjustment screw and a fixing nut. The fixing nut is fixed on the connecting plate 33. The adjustment screw passes through the connecting plate and the fixing nut and is threadedly connected to the fixing nut. A pressing component is fixed at the bottom end of the adjustment screw. By turning the adjustment screws on both sides, the pressing component can move up and down, thereby pressing the two sides of the workpiece to adjust the horizontal tilt angle of the workpiece.

[0031] In this embodiment, the control system of the fixture is set on the control handle 5. The control handle 5 is equipped with a variety of function buttons. The function buttons are electrically connected to the corresponding cylinders in the fixture. By manually operating the function buttons, the corresponding cylinders on the fixture can be controlled to work, such as clamping or releasing the workpiece, flipping the workpiece, etc.

[0032] The fixture in this embodiment can be used as an end effector, mounted on an external device, such as the end effector of a robot arm. The robot arm can then move the fixture closer to the workpiece. To connect the fixture to the external device, this embodiment includes a mounting flange 11 at the top of the mounting bracket 1 for connection with the external device. This allows the external device to control the transfer fixture to perform actions such as movement or rotation.

[0033] In summary, the clamp of this embodiment can clamp the circuit breaker pole and achieve flipping. Applying the clamp of this embodiment to the hoisting or transportation of circuit breaker poles can reduce the labor intensity of workers and improve the assembly efficiency of circuit breaker poles. At the same time, the clamp can firmly clamp the workpiece, preventing the workpiece from accidentally falling and injuring workers.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
