[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a positionable auxiliary platform for mechanical processing, including an auxiliary platform body 1. Because the four corners of the auxiliary platform body 1 are designed as curved surfaces, it can prevent the staff from bumping into the auxiliary platform body 1 and causing injuries, thereby protecting the staff. Four telescopic rods 2 are fixedly connected to the bottom of the auxiliary platform body 1, and one end of the four telescopic rods 2 is connected to a bottom plate 3. The top of the auxiliary platform body 1 is fixedly connected to a fixed frame 9, and four movable rods 21 are slidably connected to the fixed frame 9, and one end of two movable rods 21 is connected to a second triangular block 17.

[0021] A first spring 20 is sleeved on the movable rod 21, four limiting holes 18 are opened on the auxiliary platform body 1, and a second spring 23 is arranged inside the limiting hole 18. A fixing block 15 is arranged on the top of the auxiliary platform body 1, and two bearings 4 are fixedly connected to the bottom plate 3. The inner rings of the two bearings 4 are fixedly connected to the bidirectional screw rods 5.

[0022] Four limit rods 19 are fixedly connected to the bottom of the fixed block 15, the first triangular blocks 16 are fixedly connected to both sides of the fixed block 15, the U-shaped plate 12 is fixedly connected to the top of the fixed block 15, two moving blocks 6 are threadedly connected to the bidirectional screw rod 5, and the moving block 6 is hinged with a connecting rod 8.

[0023] A screw 13 is threadedly connected to the U-shaped plate 12, and a nut 14 is fixedly connected to one end of the screw 13. Because a number of grooves are provided on the nut 14, friction can be increased, which makes it convenient for the staff to turn the nut 14, thereby improving the convenience of operation. One end of the two movable rods 21 is fixedly connected to a handle 22. Because the handle 22 is designed as an arc surface, when the handle 22 is pulled to drive the movable rod 21 to move, the arc surface of the handle 22 can fit the palm, thereby improving the comfort of operation. One end of the screw 13 is fixedly connected to the splint 10, and one end of the bidirectional screw rod 5 is fixedly connected to the motor 7. Plastic pads 11 are provided on the U-shaped plate 12 and the splint 10. Because the plastic pad 11 is provided, when the splint 10 clamps the product, the plastic pad 11 can protect the product to prevent the splint 10 from damaging the product.

[0024] The working principle of the utility model is:

[0025] The fixing block 15 is placed above the auxiliary platform body 1 and placed inside the fixing frame 9. The two first triangular blocks 16 push the two second triangular blocks 17 away from each other. After a period of time, the second triangular block 17 is located in the groove formed between the first triangular block 16 and the U-shaped plate 12. The first spring 20 pushes the second triangular block 17 into the groove to fix the fixing block 15. At the same time, the limiting rod 19 overcomes the elastic force of the second spring 23 and is inserted into the limiting hole 18. At this time, the nut 14 is turned to drive the screw 13 to rotate, and the screw 13 drives the clamping plate 10 to move to clamp and position the product. When the fixed block 15 needs to be removed, the two handles 22 are pulled to make the two second triangular blocks 17 move away from each other, and the fixation of the first triangular block 16 is released. At this time, the second spring 23 pushes the fixed block 15 to rise a certain distance. The fixed block 15 can be removed by loosening the handle 22. When the height of the auxiliary platform body 1 needs to be adjusted, the starting motor 7 drives the bidirectional screw rod 5 to rotate, so that the two moving blocks 6 move away from or close to each other, and the height of the auxiliary platform body 1 is adjusted by the connecting rod 8.
