Clamping device and clamping method for machinery manufacturing

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] See Figure 1-3 The present invention provides a technical solution: a clamping device for machine manufacturing, comprising a frame 1 and a vertical plate 17, a slide rail 2 is installed inside the frame 1, and a pulley 3 is provided on the slide rail 2, and the pulley 3 passes The underframe 4 is connected to the bottom of the bottom plate 5. A first motor 6 is provided on the bottom plate 5, and the first motor 6 is connected to a hydraulic rod 7. There are two sets of hydraulic rods 7 and the hydraulic rods 7 are respectively arranged on the horizontal plate 8. The lower two sides enable the horizontal plate 8 to rise and fall smoothly. The hydraulic rod 7 and the horizontal plate 8 are connected to each other, and the horizontal plate 8 is equipped with a backing plate 9, and the backing plate 9 is equipped with a second motor 10 and a second motor 10. A rotating shaft 11 is provided at one end, a rotating rod 12 is installed on the rotating shaft 11, and a connecting block 13 is provided at one end of the rotating rod 12.

[0020] A fixed block 14 is installed on the side of the connecting block 13, and a spring 15 is installed on the fixed block 14, and the top of the spring 15 is provided with a spring pad 16; the fixed block 14 and the spring pad 16 at the upper end of the spring 15 are provided in two groups, and are fixed The spring pads 16 on the block 14 and the spring 15 are respectively arranged on the connecting block 13 and on the movable shaft 21 to facilitate the insertion of parts of different sizes and shapes that need to be clamped. The spring 15 is provided with 3 groups, and the bottom end of the spring 15 is welded On the top of the fixed block 14, and the upper end of the spring 15 and the spring pad 16 are an integral structure, so that the spring 15 is firmly installed on it, and it is not easy to fall when the parts are clamped. The shape of the spring pad 16 and the fixed block 14 are both curved And the diameter of the spring pad 16 and the fixed block 14 are the same, and the material of the spring pad 16 is rubber, and the arc can clamp parts of different shapes. The spring 15 pad is made of rubber, which is non-slip and has frictional force.

[0021] A threaded rod 18 is installed on the vertical plate 17, and one end of the threaded rod 18 is provided with a rotary button 19, and the other end of the threaded rod 18 is installed with a fixed shaft 20, and one side of the fixed shaft 20 is connected with the movable shaft 21, and the fixed shaft 20 sets Embedded on the movable shaft 21, the fixed shaft 20 and the threaded rod 18 are connected by threaded connection, and the movable shaft 21 and the fixed block 14 are connected by welding. When the second motor 10 is working, the movable shaft can be driven by the parts The connecting block 13 on the 21 rotates, and the parts can be polished by changing sides during the grinding of the parts. There is no need to change the sides manually, which saves time.

[0022] Working principle: When using this mechanical clamping device, first fix the frame 1, so that the pulley 3 on the base frame 4 is placed in the slide rail 2, so that the pulley 3 will drive the device on the bottom plate 5 to slide back and forth, which can slide To the required position, the first motor 6 on the bottom plate 5 drives the hydraulic rod 7 up and down, so that the device on the horizontal plate 8 can adjust the position up and down. The second motor 10 is installed on the backing plate 9. After the parts are placed on the spring washer 16 connected to the fixed block 14, the rotary knob 19 can be turned to extend the threaded rod 18 forward, and the fixed shaft 20 on the threaded rod 18 and the movable shaft 21 are sleeved and snapped together to be movable Rotate, and then the spring pad 16 on the fixed shaft 20 will fix the parts to be clamped with the spring pad 16 on the fixed block 14, and then it can be polished. As the parts become smaller during polishing, the spring pad 16 The force of the spring 15 is reduced, which will stretch and squeeze the parts, so that the parts will not fall due to the size of the parts after grinding. When one side of the parts is polished, and then the second motor 10 works, it will drive the rotation on the shaft 11 The rod 12 rotates, and then the connecting block 13 on the rotating rod 12 will also rotate, and then the fixed block 14 is driven, and the fixed block 14 on the fixed shaft 20 is also rotated through the parts, so that the parts can be replaced and polished. , It saves the time of manual replacement of parts and improves work efficiency.

[0023] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
