Detailed Implementation

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example 1

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a screw grinding device, including a housing 1. A support plate 12 is horizontally fixed between the lower ends of the inner walls on both sides of the housing 1. A movable plate 16 that moves back and forth is arranged parallel to each other below the support plate 12. A fixed plate 20 is connected to the movable plate 16. One end of the fixed plate 20 is movably connected to the inside of the movable plate 16, and the other end is fixedly installed on the inner wall of the housing 1. The fixed plate 20 is used to guide the movable plate 16. Slider 21 is symmetrically fixed on the upper and lower surfaces of the fixed plate 20 near the movable plate 16. The slider 21 is used to restrict the relative movement between the movable plate 16 and the fixed plate 20.

[0024] The movable plate 16 has a movable groove 18 inside one end, and one end of the fixed plate 20 is movably inserted into the movable groove 18. A spring 19 is fixedly connected between the end of the fixed plate 20 and the wall of the movable groove 18. Sliding grooves 2101 are provided on the upper and lower side walls of the movable groove 18, and the slider 21 is slidably disposed in the sliding grooves 2101.

[0025] In this embodiment, when the movable plate 16 moves, one end of it slides outside the fixed plate 20, so that the slider 21 installed on the fixed plate 20 slides in the groove 2101. The slider 21 can prevent the movable plate 16 from separating from the fixed plate 20 when it moves. At the same time, the movement of the movable plate 16 will also drive the spring 19 to stretch or compress.

[0026] This embodiment can guide the movable plate 16 and improve the stability of the movable plate 16 when it moves. The fixed plate 20 is provided and is movably inserted into one end of the movable plate 16. While providing support for the movable plate 16, it also ensures that one end of the movable plate 16 is no longer suspended in the air, thus guiding the movable plate 16.

[0027] Example 2

[0028] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 3 As shown, in order to better realize this utility model, the following arrangement is adopted: In this embodiment, a second electric telescopic rod 15 is connected to the other end of the movable plate 16. The fixed end of the second electric telescopic rod 15 is fixedly inserted into the shell wall of the box 1, and the telescopic end is connected to the movable plate 16.

[0029] A plurality of first clamping blocks 14 are fixed at equal intervals on the upper surface of the support plate 12. A second clamping block 1401 is provided on one side of each first clamping block 14 at intervals. A fixing rod 17 is fixedly connected to the lower end of the second clamping block 1401. The fixing rod 17 is vertically fixed on the moving plate 16. A through hole 13 is provided on the support plate 12 at a position corresponding to the fixing rod 17. The fixing rod 17 is slidably disposed in the through hole 13.

[0030] A rubber pad 23 is fixedly adhered to the opposite side of the first clamping block 14 and the second clamping block 1401.

[0031] The bottom wall of the second clamping block 1401 is symmetrically embedded with balls 22 located on both sides of the fixing rod 17, and the balls 22 are in rolling contact with the surface of the support plate 12.

[0032] In this embodiment, the entire clamping part, including the second electric telescopic rod, the moving plate, the fixed rod, the first clamping block, and the second clamping block, and the structure and working principle are described in the patent document with publication number CN222059768U. The screw to be ground is placed between the first clamping block 14 and the second clamping block 1401. The second electric telescopic rod 15 is activated, which drives the moving plate 16 to move. The moving plate 16 drives the fixed rod 17 to move within the through hole 13. The fixed rod 17 drives the second clamping block 1401 to move, thereby clamping the screw between the first clamping block 14 and the second clamping block 1401. The rubber pad 23 can increase the friction between the clamping block and the screw, thereby increasing the clamping force on the screw. The ball bearing 22 at the bottom of the second clamping block 1401 can guide the second clamping block 1401 when it moves.

[0033] Example 3

[0034] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 4 As shown, to further better realize this utility model, the following arrangement is specifically adopted: In this embodiment, threaded rods 3 and guide rods 4 are installed parallel and spaced apart between the top ends of the inner walls on both sides of the box 1. The guide rods 4 are fixed inside the box 1, and the threaded rods 3 are rotatably installed inside the box 1. A forward and reverse motor 2 is installed on one side of the outer wall of the box 1. The output end of the forward and reverse motor 2 is fixedly connected to one end of the threaded rod 3. A moving block 5 is threaded on the outer side of the threaded rod 3. The upper end of the moving block 5 is slidably sleeved on the guide rod 4. A first electric telescopic rod 6 is fixedly installed on the lower end of the moving block 5. A connecting plate 7 is installed on the output end of the first electric telescopic rod 6. A servo motor 8 is fixed on the connecting plate 7. A grinding head 9 is installed on the output end of the servo motor 8.

[0035] The inner walls on both sides of the box 1 are set as inclined surfaces 10 below the second electric telescopic rod 15. The bottom ends of the two inclined surfaces 10 form a collection groove between the bottom surface of the box 1 and the bottom surface of the box 1. A collection box 11 is movably installed in the collection groove. A box door 101 is rotatably installed on the outside of the box 1.

[0036] In this embodiment, the structure and working principle of the entire movable grinding part, including the threaded rod, guide rod, first electric telescopic rod, and grinding head, refer to the content described in the patent document with publication number CN222059768U. When the two clamping blocks clamp the screw, the forward and reverse motor 2 is started. The forward and reverse motor 2 drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, it drives the moving block 5 to move. The moving block 5 drives the mechanism below it to move together. When it moves to the screw to be ground, the forward and reverse motor 2 is stopped, and the first electric telescopic rod 6 is started, so that the first electric telescopic rod 6 drives the servo motor 8 to move down until grinding. The head 9 can grind the screws. Then, the first electric telescopic rod 6 is closed, and the servo motor 8 is started. The servo motor 8 drives the grinding head 9 to rotate and grind the screws. After one screw is ground, the first electric telescopic rod 6 is started again, which drives the servo motor 8 to move upward. Then, the forward and reverse motor 2 is started, which causes the moving block 5 to drive the grinding head 9 to the next screw to be ground. The above steps are repeated. The debris generated during the grinding process falls onto the inclined plane 10 and then slides down the inclined plane 10 into the collection box 11. Then, the box door 101 is opened, the collection box 11 is pulled out, and the debris in the collection box 11 can be taken out.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
