[0035] For example, see Figures 1 to 14 , including a mounting seat 1, a grinding belt 2 is mounted on the mounting seat 1, and a rotating disk 4 is arranged on the side of the grinding belt 2, and a positioning seat 9 for placing hardware is arranged above the rotating disk 4; it also includes: a connecting gear ring 6, which is fixedly mounted on the outer wall of the mounting seat 1, and a driving gear 7 is meshedly arranged on the side of the connecting gear ring 6, and an adjustment mechanism for changing the grinding contact surface of the hardware on the positioning seat 9 is arranged on the top of the driving gear 7, the adjustment mechanism includes a docking column 8 fixedly arranged on the outer wall of the driving gear 7, and a fixing rod 17 is arranged at the bottom of the driving gear 7, and a docking ball 15 is arranged at the end of the fixing rod 17, and a docking groove 16 for limiting the movement of the docking ball 15 is opened inside the mounting seat 1, and the docking groove 16 includes a smooth portion 161 and a curved portion 162 arranged in communication; a driving motor 5 is installed inside the mounting seat 1, and a driving shaft 3 for driving the grinding belt 2 to move is arranged inside the grinding belt 2; By placing the automobile hardware that needs to be polished on the positioning seat 9, and controlling the rotation of the motor installed at the end of the driving shaft 3, the driving shaft 3 is driven to rotate, so as to drive the grinding belt 2 to move. It should be noted that a limiting member (not shown in the figure) is installed between the grinding belt 2 and the mounting seat 1 to limit the running arc of the grinding belt 2. Those skilled in the art can select a suitable limiting member according to actual needs to limit the grinding belt 2 to form a specific shape. Secondly, those skilled in the art can also set the grinding belt 2 to a fixed grinding sheet. The above content belongs to the prior art, and those skilled in the art can select it according to actual needs. No further details are given here. Subsequently, the driving motor 5 inside the mounting seat 1 is started to drive the rotating disk 4 to rotate, thereby driving the automobile hardware on the positioning seat 9 to contact with the grinding belt 2, so as to realize the grinding operation on the surface of the automobile hardware. A plurality of positioning seats 9 are arranged on the rotating disk 4, so that a plurality of automobile hardware can be polished at the same time, thereby improving the grinding efficiency of the hardware. A connecting gear ring 6 is fixedly installed on the mounting seat 1. When the rotating disk 4 drives the positioning seat 9 to rotate, the rotating disk 4 will drive the driving gear 7 at the bottom to rotate along the connecting gear ring 6, and the driving gear 7 is meshed with the connecting gear ring 6, so that the driving gear 7 rotates while following the rotation of the rotating disk 4. A docking column 8 is fixedly arranged between the driving gear 7 and the positioning seat 9, thereby driving the docking column 8 and the positioning seat 9 to rotate along with the driving gear 7, so that the hardware arranged outside the positioning seat 9 is rotated and conveyed with the rotating disk 4 and contacts with the grinding belt 2 during the grinding process, and the positioning seat 9 is used to drive the hardware to rotate, so that the hardware is fully in contact with the grinding belt 2, thereby improving the grinding effect of the hardware. In this way, uniform grinding of the surface of the hardware is achieved, and the grinding error caused by fixed-point grinding is effectively avoided; A fixing rod 17 is fixedly provided at the bottom of the driving gear 7, and a docking ball 15 is fixedly connected to the end of the fixing rod 17. When the driving gear 7 rotates with the rotating disk 4, it will drive the docking ball 15 to slide inside the docking groove 16.

When the docking ball 15 slides into the curved portion 162, the curved portion 162 is arranged in a wave shape, thereby driving the docking ball 15, the driving gear 7 and the positioning seat 9 to slide up and down. When the positioning seat 9 slides up and down, it will drive the hardware to slide up and down on the surface of the grinding belt 2. In this way, the hardware can be self-rotated and polished while following the rotation and grinding of the rotating disk 4, and an up and down motion grinding is superimposed, thereby further improving the grinding effect on the outer surface of the hardware and improving the grinding efficiency.

[0036] As another optional scheme of the adjustment mechanism of the present invention, the adjustment mechanism includes a reciprocating screw 42 fixedly arranged on the outer wall of the driving gear 7, and the external thread of the reciprocating screw 42 is connected to a lifting block 43, a fixed ball head 44 is arranged on the top of the lifting block 43, and the outside of the fixed ball head 44 is covered with a docking shaft 45, and the outer wall of the docking shaft 45 is provided with a fixed protrusion 46, the interior of the rotating disk 4 is provided with a second spiral groove 47 for limiting the sliding of the fixed protrusion 46, the lifting block 43 is slidably arranged inside the rotating disk 4, and the reciprocating screw 42 is rotatably arranged inside the rotating disk 4; When the rotating disk 4 drives the driving gear 7 to mesh with the connecting gear ring 6, the driving gear 7 will drive the reciprocating screw 42 fixed on the top to rotate inside the rotating disk 4, and the reciprocating screw 42 will be threadedly connected with the lifting block 43. When the reciprocating screw 42 rotates, it will drive the lifting block 43 and the fixed ball head 44 fixed on the top of the lifting block 43 to slide up and down inside the rotating disk 4. The lifting block 43 can only slide inside the rotating disk 4 and cannot rotate. When the fixed ball head 44 slides up and down, it will drive the docking shaft 45 and the positioning seat 9 to move up and down, so that the hardware set outside the positioning seat 9 moves up and down while following the rotation of the rotating disk 4, so that the hardware will slide up and down when it contacts and grinds with the grinding belt 2, so that the hardware can be superimposed with a longitudinal grinding on the basis of the transverse grinding; A fixing protrusion 46 is fixed to the outer wall of the docking shaft 45, and the fixing protrusion 46 is slidably arranged inside the second spiral groove 47. By utilizing the arrangement of the spiral second spiral groove 47, the fixing ball head 44 and the docking shaft 45 are movably connected. When the fixing ball head 44 drives the docking shaft 45 to move upward, the fixing protrusion 46 will slide in the second spiral groove 47, thereby driving the positioning seat 9 fixed at the end of the docking shaft 45 to slide up and down and rotate forward and reversely, thereby allowing the hardware outside the positioning seat 9 to be horizontally and longitudinally polished with the polishing belt 2 while superimposing a forward and reverse polishing, thereby improving the polishing effect on the surface of the hardware.

[0037] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. In order to realize the rapid positioning of the positioning seat 9 and the hardware, and avoid the mutual displacement between the hardware and the positioning seat 9 during the rotating conveying and grinding of the hardware, thereby affecting the grinding effect, for details, please refer to Figures 1 to 14 The inner core rod 12 is slidably provided inside the positioning seat 9, and the end of the inner core rod 12 is hingedly provided with a docking rod 11, and the end of the docking rod 11 is hingedly provided with a support block 10, the inner core rod 12 is penetrated and arranged inside the driving gear 7, and the end of the inner core rod 12 is provided with a limiting ball head 13, and the interior of the mounting seat 1 is provided with a limiting groove 14 for limiting the sliding of the ball head 13, and the limiting groove 14 includes a smooth groove 141, an ascending groove 142, a wave groove 143 and a descending groove 144 which are connected in sequence; The inner sliding of the driving gear 7 and the positioning seat 9 is provided with an inner core rod 12, and the end of the inner core rod 12 is fixed with a limiting ball head 13. When the rotating disk 4 drives the driving gear 7 to rotate, it will also drive the limiting ball head 13 to slide inside the limiting groove 14. The limiting ball head 13 initially slides inside the smooth groove 141. At this time, the hardware to be polished is placed above the positioning seat 9. As the rotating disk 4 drives the driving gear 7 to rotate, the limiting ball head 13 will slide from the smooth groove 141 to the rising groove 142, and the rising The height of the groove 142 is higher than that of the smooth groove 141. At this time, the limiting ball head 13 will drive the inner core rod 12 to slide inside the driving gear 7 and the positioning seat 9. When the inner core rod 12 slides, it will drive the docking rods 11 hinged on both sides to move. The docking rods 11 are hinged with the support blocks 10 and the support blocks 10 are slidably arranged inside the positioning seat 9. When the inner core rod 12 slides upward, it drives the support blocks 10 on both sides to slide outward, so that the support blocks 10 are in contact with the inner wall of the hardware, so as to realize the top support positioning of the hardware; As the rotating disk 4 continues to rotate, the limiting ball head 13 will slide into the wave groove 143, and the wave-shaped trajectory of the wave groove 143 will coincide with the smooth portion 161, so that the hardware will still be in a positioning state when sliding up and down; The surface of the support block 10 close to the inner wall of the hardware is provided with an elastic part, which can produce a certain degree of expansion and contraction. The setting of the elastic part is used to achieve stable positioning of the hardware. The elastic part can be rubber, and technical personnel in this field can select it according to actual needs. When the limiting ball head 13 slides to the descending groove 144, the inner core rod 12 slides downward at this time, driving the support block 10 to slide into the inside of the positioning seat 9, releasing the clamping and positioning of the hardware. When the limiting ball head 13 slides into the smooth groove 141 again, the processed hardware is taken out. It should be noted that the inner wall of the connecting toothed ring 6 located at the smooth groove 141, the ascending groove 142 and the descending groove 144 is not provided with a tooth mouth. At this time, the driving gear 7 is in the smooth groove 141, the ascending groove 142 and the descending groove 144, and will not mesh with the connecting toothed ring 6. When the driving gear 7 drives the positioning seat 9 on the reciprocating screw 42 to reciprocate up and down, the limiting ball head 13 moves up and down under the guidance of the wave groove 143, which can still ensure the support and positioning of the hardware by the support block 10 on the positioning seat 9.

[0038] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2, and further solves the problem that during the grinding process of hardware, the hardware will generate a certain amount of heat due to friction. For some hardware with thin outer walls, thermal stress is easily generated, which leads to an increase in the defective rate of hardware.

The resistance groove 41 is arranged in a wave shape, and the length from the lowest point to the highest point of the resistance groove 41 is greater than the length from the lowest point to the highest point in the wave groove 143. Then, when the extrusion seat 40 slides in the resistance groove 41, it will intermittently resist the extrusion seat 40 in the limiting ball head 13, allowing the extrusion seat 40 to slide in the liquid storage tank 39 and squeeze the liquid inside the liquid storage tank 39, allowing the liquid to flow from the connecting groove 38 into the inner core rod 12. As the liquid flows, it will resist the sealing seat 36, thereby driving the sealing seat 36 and the top support rod 29 to slide in the inner core rod 12 and the connecting spring 37.

When the movable seat 31 slides upward, it rotates, and the movable seat 31 is provided with a spray port 35 at an equal angle. The spray port 35 is used to spray liquid on the inner wall of the hardware to cool it down. During the liquid spraying process, the liquid will rotate and spray up and down at the same time, so that the liquid spray on the inner wall of the hardware is more uniform, thereby improving the cooling effect on the hardware. It should be noted that there is a certain distance between the top of the movable seat 31 and the top of the inner wall of the automobile hardware, and space is reserved to accommodate the movable seat 31 to rise and rotate.

[0039] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3.

During the upward movement of the driving gear 7, it will resist the resistance ring 18 connected by the surface sliding connection, so that the resistance ring 18 drives the blocking plate 19 to slide inside the docking shell 20 and stretches the docking spring 21. When the blocking plate 19 slides upward, it will squeeze the liquid inside the docking shell 20, allowing the liquid inside the docking shell 20 to enter the connecting ring groove 26 through the connecting pipe 25. The connecting ring groove 26 is sleeved on the docking column 8 and is connected to the docking column 8, allowing the liquid to enter the docking column 8 through the connecting ring groove 26, and enter the top support rod 29 through the circulation pipe 28. The top support rod 29 and the top support ball head 30 are provided with holes for liquid flow, so that the liquid can flow into the circulation groove 34 through the top support rod 29 and the top support ball head 30, and finally be sprayed out from the injection port 35; When the driving gear 7 moves downward, the docking spring 21 drives the docking shell 20 to reset, and a one-way valve 23 is arranged inside the connecting pipe 25 (liquid can only flow from the docking shell 20 to the connecting ring groove 26). At this time, a suction negative pressure will be generated in the docking shell 20. A sealing ring plate 22 is fixed on the top of the docking shell 20, and the two are connected, so that the liquid in the water storage tank 24 can flow smoothly into the docking shell 20, so that the next time the docking shell 20 moves upward, the liquid will be squeezed out from the injection port 35.
