[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3 , the utility model provides a technical solution:

[0020] A gripping device for mechanical manufacturing, comprising a mounting frame 1, a support frame 2 fixedly connected to the mounting frame 1, and clamping claws 3 movably mounted on both sides of the support frame 2. A lifting chamber is provided inside the support frame 2, a rotating shaft 4 and a driving mechanism for driving the rotating shaft 4 are installed inside the lifting chamber, a moving block 5 is connected to the outer side of the rotating shaft 4 through an external thread groove spiral transmission, and connecting rods 6 are installed on both sides of the moving block 5 respectively passing through the outside of the support frame 2. One end of the clamping claw 3 is movably connected to the connecting rod 6 through movable shaft 1, and is movably connected to the support frame 2 through movable shaft 2. The other end is provided with a fixed seat 8 and a clamping block 7 detachably mounted in the fixed seat 8.

[0021] When in use, the grasping device can be installed through the mounting frame 1. When working, the driving mechanism is started to drive the rotating shaft 4 to rotate, so that the moving block 5 can make a linear motion outside the rotating shaft 4, and at the same time drive the connecting rod 6 to move, thereby driving the two clamping claws 3 to rotate around the movable axis 1 and the movable axis 2, so as to achieve the purpose of opening and closing the clamping parts. The structure is simple and the operation is convenient. In actual operation, different clamping blocks 7 can be replaced according to the size of the parts, thereby increasing the contact area between the parts and the clamping blocks 7.

[0022] Through holes are provided on both sides of the lifting cavity, and both sides of the moving block 5 pass through the through holes to cooperate with the moving block 5 to perform linear motion.

[0023] The driving mechanism includes a bevel gear 1 installed at one end of the rotating shaft 4 and a bevel gear 2 meshing with one side of the bevel gear 1. A servo motor driving the bevel gear 2 is installed on the outside of the support frame 2. The servo motor drives the bevel gear 2 to rotate, and under the meshing transmission of the bevel gear 1, the rotating shaft 4 is driven to rotate.

[0024] A fixed shaft is installed on one side of the clamping block 7, and a number of anti-slip ridges are provided inside the other side to further improve the firmness of the grip.

[0025] Rubber pads are installed on the bottom wall of the installation groove and one side of the limiting block 11.

[0026] A mounting groove is provided in the middle of the fixing seat 8, and the fixed shaft is fixed in the mounting groove. A threaded rod 9 is threadedly connected on one side of the mounting groove, and a limiting hole is provided on the other side. A limiting rod 10 is slidably installed inside the limiting hole. A baffle and a spring are sleeved on the outside of the limiting rod 10. One end of the spring is connected to the baffle, and the other end is connected to the inner wall of the limiting hole. One end of the limiting rod 10 and the threaded rod 9 pass through the mounting groove and are provided with a limiting block 11. During installation, first rotate the threaded rod 9 according to the diameter of the fixed shaft, roughly adjust the position of the limiting block 11 at the bottom, and then pull the limiting rod 10 downward to insert the fixed shaft into the mounting groove. The fixed shaft is clamped and fixed between the two limiting blocks 11 by the elastic force of the spring, which is convenient for installation and disassembly to replace the clamping block 7.

[0027] It should be noted that in order to improve the stability of the installation, electromagnets with opposite magnetic properties are installed inside the two limit blocks 11 respectively, and a control button electrically connected to the electromagnet is installed on the outside of the fixing seat 8. After the installation is completed, the control button can be pressed to energize the electromagnet, so that the two limit blocks 11 generate a force of mutual attraction under the action of magnetism, thereby improving the fixing strength.
