Please refer to Figures 1-3, an embodiment provided by the present invention: a clamping device for the production and processing of mechanical parts, including a servo motor 5, a workbench 6 and a support leg 7, and a bolt is used on one side of the top of the workbench 6 The control host 8 of model KD-RBOP is fixedly installed, and the control host 8 has a programming system, which can program the drive structure of the entire device to make it automatically rotate. The top side of the workbench 6 is fixed with a model 130ST with bolts. The servo motor 5 of M15025 is the main rotating device. The top rotation of the servo motor 5 is equipped with a rotating disk 501. The rotating disk 501 can drive the top device to rotate. Through the rotation, the clamped materials can be transferred in position. The motor 5 is rotated and installed with a support arm 4 through the rotating disk 501, which mainly accepts the movement of the top device. The support arm 4 is inlaid and installed with a connecting arm 3 through a slot, and the support arm 4 and the connecting arm 3 are fixed by a fixed knob 401, It can be installed and disassembled more conveniently, bringing better convenience to later maintenance work. The connecting arm 3 is movably installed with an electric push rod 2 through the first rotary joint 301. The electric push rod 2 is mainly composed of a motor, a push rod and A linear actuator composed of a control device and other mechanisms. The motor drives a pair of screw nuts through a pair of gears to reduce the rotation of the motor into a linear motion. The motor is used to complete the push and pull action in the forward and reverse directions, thereby driving the clamp 1103 to move the position. , The output end of the electric push rod 2 is fixed and installed with a hydraulic telescopic rod 9 through the connecting seat 1 using bolts. The hydraulic telescopic rod 9 is composed of a cylinder, a piston and a connecting rod. There is a piston in the cylinder that is in close contact with the inner wall of the cylinder. , The top of the piston is connected with a telescopic rod. The lower and upper ends of the piston are filled with hydraulic oil. When the hydraulic pump injects hydraulic oil into the lower end of the piston, the piston moves downwards, the connecting rod extends, and the hydraulic oil at the upper end of the piston is discharged from the connecting pipe.

The rod 1102 pushes the clamp 1103 to slide to the inside to achieve the purpose of clamping. When the push column 901 drives the sliding rod 902 to lift up, the movable rod 1102 can drive the clamp 1103 to slide outward, so that the clamp 1103 opens and loosens the material. This structure is relatively stable, can reduce the maintenance frequency of the operators, and can hold and transfer materials more stably for a long time.

The inside of the clamp 1103 is fixed and installed with a clamp head 1104 with bolts, and the inside of the clamp head 1104 is evenly distributed with anti-skid teeth, which can effectively fit the surface of the material to increase friction, prevent falling, enhance safety, and facilitate maintenance.
