A spring is used to keep the sandpaper in constant contact with the grinding surface. This invention, by setting an extruder, uses a motor to drive a rotating shaft and a triangular chuck via a belt, causing the fastener to rub and grind against the sandpaper. Because the spring inside the extruder is compressed, it slowly rebounds as the fastener shrinks, ensuring that the sandpaper surface remains in constant contact with the fastener grinding surface without the need for further adjustment, thus improving work efficiency. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the sandpaper surface is guaranteed to always be in contact with the fastener grinding surface without the need for further adjustment, thus improving work efficiency, dust and debris are generated during grinding.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, this utility model provides a surface grinding device for bolt fasteners, including a workbench 1. A support plate 3 and a fixed plate 6 are fixedly installed on the top of the workbench 1. A hydraulic cylinder 7 is fixedly installed on the outer wall of the fixed plate 6.

Multiple evenly distributed first springs 803 are fixedly installed on the outer wall of the moving plate 801. An extension ring 804 is fixedly installed at one end of each of the multiple first springs 803.

[0024] The effect achieved by the entire embodiment 1 is as follows: when the extension ring 804 contacts the support plate 3, the first spring 803 is compressed. At this time, the debris generated during grinding can be blocked by the protective ring 802 and the extension ring 804, and finally fall along the inner wall of the protective ring 802 and the extension ring 804 onto the inner bottom surface of the protective ring 802 and the extension ring 804. When grinding is finished, the operator starts the cylinder 805, and the first scraper 806 moves to push away the debris until it is pushed into the extension ring 804. At this time, the first iron piece 810 enters the storage groove 807 and is attracted together with the first magnet 808. At this time, the second scraper 809 begins to move under the push of the first scraper 806 until the debris is pushed out of the extension ring 804, which is convenient for the operator to clean.

[0025] Example 2, as Figures 1-4As shown, the inner wall of the movable plate 801 is further provided with a grinding structure 9, which includes a U-shaped plate 901. Electric telescopic rods 902 are fixedly installed on both sides of the outer side of the U-shaped plate 901. The telescopic end of the electric telescopic rod 902 passes through the U-shaped plate 901 and is fixedly installed with a connecting plate 903.

[0026] Furthermore, two slots 904 are symmetrically opened on the outer wall of the connecting plate 903. A limiting groove 907 is opened on the inner wall of the slot 904. A second spring 909 is fixedly installed on the inner wall of the limiting groove 907. A locking block 910 is fixedly installed on one end of the second spring 909. A through opening 908 is opened through the inner wall of the limiting groove 907. A pull plate 911 is fixedly installed on the end of the locking block 910 near the through opening 908. A baffle 912 is fixedly installed on the outer wall of the pull plate 911.

[0027] Furthermore, a sandpaper 905 is provided on the outside of the connecting plate 903, and two slots 906 are opened through the outer wall of the sandpaper 905.

[0028] Furthermore, the outer wall of the movable plate 801 is fixedly connected to the output end of the hydraulic cylinder 7, and a limit rod 814 is fixedly installed on the outer wall of the extension ring 804. One end of the limit rod 814 is slidably inserted into the movable plate 801 to limit the extension ring 804.

[0029] Furthermore, a motor 4 is fixedly installed on the outer wall of the support plate 3, and the output end of the motor 4 passes through the support plate 3 and is fixedly installed with a clamp 5.

[0030] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the workbench 1.

[0031] The effect achieved by the entire embodiment 2 is that when replacing sandpaper 905, the worker pulls the two pull plates 911, the locking block 910 leaves the slot 906, the second spring 909 is compressed, and at this time the sandpaper 905 can be taken out. Then, the two ends of the sandpaper 905 are inserted into the two slots 904 respectively. The pull plates 911 are released, and the elastic force of the second spring 909 pushes the locking block 910 into the slot 906. In this way, the replacement can be completed, which improves the replacement efficiency.

[0032] Working principle: In use, the operator clamps the fastener using clamp 5, then activates two electric telescopic rods 902 according to the size of the fastener. The telescopic ends of the two electric telescopic rods 902 extend and push the connecting plate 903 to move, controlling the distance between the two sandpapers 905. Then, the hydraulic cylinder 7 is activated, and the output end of the hydraulic cylinder 7 pushes the two sandpapers 905 to the fastener. The motor 4 is started, and the fastener rotates to begin grinding. During grinding, the extension ring 804 approaches the support plate 3. When the extension ring 804 contacts the support plate 3, the first spring 803 is compressed. At this time, the debris generated during grinding is blocked by the protective ring 802 and the extension ring 804. Finally, the debris is blocked along the protective ring 802 and the extension ring 804. The inner wall of ring 804 rests on the bottom surface of the protective ring 802 and the extension ring 804. When the grinding is finished, the operator starts the cylinder 805, and the first scraper 806 moves to push away the debris until it is pushed into the extension ring 804. At this time, the first iron piece 810 enters the storage groove 807 and is attracted to the first magnet 808. Then, the second scraper 809 starts to move under the push of the first scraper 806 until the debris is pushed out of the extension ring 804 for easy cleaning by the operator. Then the first scraper 806 is reset, and the second iron piece 813 enters the fixing groove 811 and is attracted to the second magnet 812. At this time, the first iron piece 810 can be detached from the storage groove 807, thus completing the cleaning. When replacing sandpaper 905, the worker pulls the two pull plates 911, the locking block 910 disengages from the slot 906, and the second spring 909 is compressed. At this point, sandpaper 905 can be removed. Then, the two ends of sandpaper 905 are inserted into the two slots 904 respectively. The pull plates 911 are released, and the elastic force of the second spring 909 pushes the locking block 910 into the slot 906. This completes the replacement and improves the replacement efficiency.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
