[0022] 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.

[0023] Please see Figures 1-6This utility model provides the following technical solution: a grinding device for processing hardware products, including a workbench 1, a first side frame 2 connected to the surface of the workbench 1, a first motor 3 installed on the top of the first side frame 2, a lead screw 4 connected to the bottom of the first motor 3 by bolts, the bottom of the lead screw 4 being sleeved in a bearing provided on the inner wall of the first side frame 2, a threaded block 5 connected to the surface of the lead screw 4 by threads, a top plate 6 connected to the other side surface of the threaded block 5, a slider 7 connected to the other end surface of the top plate 6, the slider 7 being slidably connected to the surface of a slide rod 8 provided on the inner wall of a second side frame 9, the bottom surface of the second side frame 9 being connected to the top of the workbench 1, a mounting bracket 10 provided on one side bottom of the top plate 6, a second motor 12 threadedly connected to the surface of the mounting groove on the top of the mounting bracket 10 by a first fixing bolt 11, a grinding disc 13 threadedly connected to the surface of the shaft of the second motor 12 by bolts, a crossbar surface of the other end of the grinding disc 13 being sleeved in a bearing provided on the top of the top plate 6, a fourth motor 14 installed on one side surface of the workbench 1, and a bidirectional lead screw 15 threadedly connected to the shaft of the fourth motor 14 by bolts.

[0024] Preferably, the other side of the bidirectional lead screw 15 is sleeved in the bearing provided on the other end surface of the worktable 1, and the surface of the bidirectional lead screw 15 is threadedly connected to the bottom block 16. The surface of the bottom block 16 is threadedly connected to the rectangular frame surface provided on one side of the clamping ring 18 by the second fixing bolt 17.

[0025] In practical use, the bearing on one side of the worktable 1 facilitates the rotation of the bidirectional lead screw 15 in place under the drive of the fourth motor 14, thereby driving the bottom blocks 16 threaded to both sides of the bidirectional lead screw 15 to move simultaneously toward the midpoint of the top of the worktable 1.

[0026] Preferably, a limiting rod 19 is provided at the top of the rectangular frame on one side of the clamping ring 18, the surface of the limiting rod 19 is sleeved on the surface of the limiting frame on one side of the first protective cover 20, and a rubber sleeve 21 is bonded to the surface of the open end of the first protective cover 20.

[0027] In practical use, the rubber limiting rod 19 at the top of the clamping ring 18 allows the limiting brackets at the bottom of the first protective cover 20 and the second protective cover 22 to be fitted onto the top of the clamping ring 18, increasing the friction between the two contact surfaces and thus fixing their connection with the clamping ring 18.

[0028] Preferably, the other side of the rubber sleeve 21 is movably sleeved onto the opening end of the second protective cover 22, and the bottom surface of the second protective cover 22 is sleeved onto the surface of the limiting rod 19.

[0029] In practical use, the rubber sleeve 21 bonded to the surface of the opening end of the first protective cover 20 can be fitted onto the opening end of the second protective cover 22 when the second protective cover 22 moves and abuts against the opening end of the first protective cover 20, thereby blocking the gap between the first protective cover 20 and the second protective cover 22 and preventing debris from splashing out from the gap where the two intersect.

[0030] Preferably, the top surface of the workbench 1 is engaged with the plug 23, and the other side surface of the plug 23 is connected to the dustproof brush 24, with the surface of the dustproof brush 24 abutting against the rectangular slide groove surface opened on the top of the workbench 1.

[0031] In practical use, the insert block 23 on one side of the dustproof brush 24 is inserted and locked onto the top of the worktable 1, thereby fixing the position of the dustproof brush 24 on the rectangular slide groove on the top of the worktable 1, thus blocking its open end and preventing a large amount of debris generated during processing from falling onto the surface of the bidirectional lead screw 15 on the top of the worktable 1.

[0032] Preferably, one side of the clamping ring 18 has a semi-circular structure, and the other side surface has a rectangular frame, and the shape and size of the groove on the inner wall of the rectangular frame are adapted to the upper end of the bottom block 16.

[0033] In practical use, the rectangular frame on one side of the clamping ring 18 can be easily fitted onto the top of the base block 16 to fix the connection between the two. At the same time, the rubber pad on the inner wall surface of the clamping ring 18 can provide protective clamping to the surface of the hardware product it clamps. This not only protects the surface of the hardware product from damage caused by rigid contact, but also increases the friction between the clamping ring 18 and the surface of the hardware product, thereby making the clamping of the clamping ring 18 more stable.

[0034] Preferably, the opening ends of the first protective cover 20 and the second protective cover 22 are both provided with rectangular grooves, and the shape and size of the rectangular grooves are adapted to the top plate 6.

[0035] In practical use, the grooves opened on the surfaces of the first protective cover 20 and the second protective cover 22 are respectively fitted onto both sides of the surface of the top plate 6. At the same time, the grooves opened on the surfaces of the first protective cover 20 and the second protective cover 22 allow the height of the top plate 6 to be slightly adjusted on both surfaces.

[0036] Working principle: During the processing of hardware products, the surface of the product is polished using a grinding disc 13. Depending on the shape and size of the hardware product to be processed, a clamping ring 18 of appropriate shape is selected. The rectangular frame on one side of the clamping ring 18 is then fitted onto the top of the base block 16. A second fixing bolt 17, threaded through the rectangular frame on the surface of the clamping ring 18, is then threaded onto the surface of the base block 16, thus fixing the clamping ring 18 at the top of the base block 16. In actual use, the clamping rings 18 are sequentially threaded onto the base block 16, with both ends threaded onto the double-acting screw 15. The hardware product to be processed is then placed at the midpoint of the top of the worktable 1, which is located at the bottom of the grinding disc 13. At the vertically lower position, based on the height of the hardware product placed on the workbench 1, the first motor 3 is started, causing the connected lead screw 4 to rotate within the bearing located on the inner wall of the first side frame 2. This causes the threaded block 5, threadedly connected to the lead screw 4, to drive the connected slider 7 to slide downwards on the slide rod 8, thereby stabilizing the downward sliding of the grinding disc 13 on the top plate 6 until the grinding disc 13 is 1 cm above the top of the hardware product. Then, the fourth motor 14 is started, causing the connected bidirectional lead screw 15 to rotate within the bearing located at the other end of the workbench 1. This causes the bottom blocks 16, threadedly connected to both sides of the bidirectional lead screw 15, to move simultaneously towards the top of the workbench 1. Finally, the clamping device connected to the top of the bottom block 16... The clamping rings 18 abut against each other on both sides of the surface of the hardware product, thereby clamping and fixing it. As the clamping rings 18 on both sides move towards the surface of the hardware product placed on the top of the workbench 1, the first protective cover 20 and the second protective cover 22, which are sleeved on the surface limiting rods 19, simultaneously move towards the center of the top of the workbench 1. When the open ends of the two clamping rings 18 abut against each other, the first protective cover 20 and the second protective cover 22, respectively connected to their surfaces, also abut against each other. Simultaneously, the grooves on the surfaces of the first protective cover 20 and the second protective cover 22 are respectively sleeved on both sides of the surface of the top plate 6. Then, the first motor 3 is restarted to rotate and drive the top plate 6 downwards again until it abuts against the surface of the hardware product. The second motor 12, which is connected to the grinding disc 13, is started to grind the surface of the hardware product that is abutted against the bottom of the grinding disc 13. The debris and dust generated during grinding are protected by the first protective cover 20 and the second protective cover 22 that are abutted against each other, so as to prevent them from splashing into the environment of the processing workshop and affecting the subsequent cleaning work. In addition, the rectangular sliding groove surface of the top of the worktable 1, which facilitates the movement of the bottom block 16, is plugged into the groove of the top of the worktable 1 by the rubber "T" shaped insert 23 on one side of the dustproof brush 24, thereby blocking the rectangular sliding groove on the top of the worktable 1 and preventing a large amount of debris generated during processing from falling into the surface of the bidirectional lead screw 15 provided on the top of the worktable 1, thereby affecting the smoothness of the movement of the bottom block 16.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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.
