[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figure 2 and Figure 6 Existing dust-free screw grinding devices generate dust during screw grinding, making it difficult to make the grinding device dust-free. To solve this technical problem, this embodiment discloses the following technical content.

[0029] A vacuum head 12 is fixedly connected to the rear side of the upper surface of the operating table 1, and the rear end of the vacuum head 12 is connected to the front end of the collection box 13. A suction pump 14 is fixedly connected to the upper rear side of the collection box 13. A dustproof net 15 is fixedly connected to the front inner side of the connection between the collection box 13 and the suction pump 14, and a top cover 16 is snapped onto the top of the collection box 13.

[0030] The vacuum head 12 is positioned slightly above the fixing mechanism 2, and the collection box 13 is placed at the middle of the rear end of the upper surface of the operating table 1. When grinding screws, the suction pump 14 is started. When the suction pump 14 is running, the dust generated during grinding is sucked from the vacuum head 12 into the collection box 13. Since a dustproof net 15 is installed inside the connection between the suction pump 14 and the collection box 13, the collected dust will not enter the suction pump 14. When the collection box 13 is full, the top cover 16 is pulled upwards away from the collection box 13, and the dust in the collection box 13 can be collected and disposed of.

[0031] Example 2: Existing dust-free screw grinding devices are inconvenient for fixing screws during grinding, and due to the large number of screws, it is inconvenient to grind multiple screws simultaneously. Therefore, this example uses the following technical solution, such as... Figures 1-5 As shown;

[0032] The fixing mechanism 2 is composed of a first motor 201, a pulley 202, a connecting rod 203, a threaded rod 204, a rotating rod 205, a fixing box 206, a clamping plate 207, and an arc-shaped groove 208. The first motor 201 is fixedly connected to the middle of the front end of the lower surface of the operating table 1, and the output shaft of the first motor 201 is fixedly connected to the pulley 202. A set of pulleys 202 is installed at both the front and rear ends of the middle part of the operating table 1, and the connecting rod 203 is fixedly connected to the inner bottom of the pulley 202. Furthermore, a threaded rod 204 is fixedly connected to the inner side of the top end of the connecting rod 203, and a rotating rod 205 is threadedly connected to the outer side of the threaded rod 204. A fixing box 206 is connected through the inner end of the rotating rod 205, and the fixing box 206 is fixedly connected to the middle of the upper surface of the operating table 1. A clamping plate 207 is rotatably connected to the inner side of the rotating rod 205, and the lower surface of the clamping plate 207 is in contact with the upper surface of the operating table 1. Several arc-shaped grooves 208 are equally spaced from left to right on the inner side of the clamping plate 207.

[0033] Automatic telescopic rods 4 are fixedly connected to the top left, middle and right ends of the mounting frame 3, and a square frame 5 is fixedly connected to the output end of the automatic telescopic rod 4. A second motor 6 and several gear discs 7 are respectively installed on the upper and lower ends of the inner side of the square frame 5. The output shaft of the second motor 6 is fixedly connected to the middle of the upper surface of the middle gear disc 7, and the gear discs 7 are meshed together. A square rod 8 is fixedly connected to the middle of the lower surface of the gear disc 7. The lower surface of the square frame 5 is fixedly connected to the connecting plate 9 by several bolts. Several grinding blocks 10 are rotatably connected to the lower surface of the connecting plate 9, and a square groove 11 is opened in the middle of the upper surface of the grinding block 10. The bottom end of the square rod 8 is engaged with the square groove 11.

[0034] Before grinding, the screws need to be placed on the fixing mechanism 2. First, ensure that the distance between the front and rear clamping plates 207 is the maximum distance. Then, place the screws into the arc-shaped grooves 208 one by one. Multiple arc-shaped grooves 208 are provided so that multiple screws can be ground simultaneously. After all the screws are placed in the arc-shaped grooves 208 within the clamping plates 207, start the first motor 201. The output shaft of the first motor 201 drives the pulley 202 to rotate. A plate is rotatably connected to the upper outer side of the pulley 202. The plate at the upper end of the pulley 202 is fixedly connected to the operating table 1, providing support for the pulley 202. Since the front and rear pulleys 202 are fixedly connected by the connecting rod 203, the front and rear pulleys 202 can rotate simultaneously, causing the threaded rod 204 at the top of the pulleys 202 to rotate simultaneously. The threaded rod 204 and the rotating rod 205 are threadedly connected. Since the rotating rod 205 has a square structure, when the threaded rod 204 rotates, the rotating rod 205 moves back and forth in the fixed box 206. The rotating rod 205 moves the clamping plate 207, and the front and rear clamping plates 207 move in opposite directions. The clamping plates 207 move inward at the same time, clamping and fixing the screw, so that the screw can be ground.

[0035] When grinding, the automatic telescopic rod 4 is activated. The output end of the automatic telescopic rod 4 moves the square frame 5 downward, so that the grinding block 10 moves to the outside of the screw. Then the second motor 6 is activated. The output shaft of the second motor 6 rotates the gear plate 7. Since the gear plates 7 are meshed together, the gear plates 7 can rotate the grinding block 10 at the bottom at the same time, and grind the screws at the same time.

[0036] Since the connecting plate 9 is fixed to the bottom of the square frame 5 by bolts, when the connecting plate 9 is removed, the bottom end of the square rod 8 on the bottom of the gear plate 7 separates from the square groove 11, and different types of grinding blocks 10 can be replaced according to the diameter of the screw.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
