[0033] Example 1:

[0034] like Figures 1 to 7As shown, this embodiment provides an adaptive parts grinding and polishing device, comprising: a support frame 1, with a bottom platform 11 disposed below the support frame 1 and a top platform 12 disposed above the support frame 1 away from the bottom platform 11; an adaptive grinding component 2 disposed at the bottom of the top platform 12, with an abrasive belt 214 disposed at the lower end of the top platform 12 for grinding parts; a lifting component 3 disposed at the upper end of the bottom platform 11, with a telescopic column 36 located above the bottom platform 11 for lifting parts for grinding; and a sliding component 4 disposed at the upper end of the lifting component 3, with a clamping block 454 located above the lifting component 3 for clamping parts.

[0035] In this embodiment, the adaptive grinding component 2 and the sliding component 4 constitute an adaptive part grinding and polishing device according to this application.

[0036] It should also be understood that the drive motor 211 and the stepper motor 31 are common knowledge in the field. They are used without modification, so the control method and circuit connection will not be described in detail.

[0037] In addition, in this embodiment, the polished parts need to be placed inside the parts placement slot 453 first. The user rotates the knob 451, rotates the threaded rod 452, and rotates the clamping block 454 to move towards the parts and clamp them. Then the user starts the drive motor 211. The output end of the drive motor 211 drives the drive wheel 212 to rotate. The drive wheel 212 drives the outer sanding belt 214 and the tension wheel 213 to rotate.

[0038] It should be noted that the part is placed on the bottom platform 11, the telescopic column 36 of the lifting component 3 lifts the part, the clamping block 454 of the sliding component 4 clamps the part, and the sanding belt 214 of the adaptive grinding component 2 grinds the part, realizing automatic grinding of the part and adapting to parts of different heights and shapes.

[0039] Specifically, the adaptive polishing component 2 includes: a polishing component 21, which is disposed at the bottom of the top platform 12; and multiple sets of upper and lower adaptive components 22, which are located inside the polishing component 21.

[0040] In this embodiment, the polishing component 21 drives the sanding belt 214 to rotate, and the up-down adaptive component 22 automatically adjusts the position of the sanding belt 214 according to the height of the part to ensure that the sanding belt 214 is in full contact with the surface of the part and improve the polishing effect.

[0041] Specifically, the sliding assembly 4 includes: a push rod 41, disposed on one side of the lifting platform 34; a clamping sliding block 42, which slides inside the lifting platform 34 and is connected at one end to the push rod 41; a slide groove 43, which is formed on both sides of the inner wall of the lifting platform 34; two sets of sliders 44, which are fixed on both sides of the clamping sliding block 42 and are embedded in the slide groove 43 and slide; and multiple sets of clamping assemblies 45, which are located inside the clamping sliding block 42.

[0042] In this system, push rod 41 pushes clamping sliding block 42 to slide within slide groove 43, slider 44 guides the sliding direction, and clamping assembly 45 adjusts the clamping position to achieve flexible sliding of clamping block 454, adapting to parts of different sizes.

[0043] Specifically, the polishing assembly 21 includes: a drive motor 211, disposed on one side of the bottom of the top platform 12; a drive wheel 212, rotating on one side of the bottom of the top platform 12 and connected to the output end of the drive motor 211; a tension wheel 213, rotating on the bottom of the top platform 12 away from the drive wheel 212; an abrasive belt 214, sleeved on the drive wheel 212 and the tension wheel 213; a sliding shaft 215, disposed on one side of the bottom of the top platform 12 and passing through the center of the tension wheel 213; a crank handle 216, located at one end of the sliding shaft 215; an adjusting screw 217, threadedly connected to one end of the sliding shaft 215 and connected to the crank handle 216 at the other end; and a locking nut 218, threadedly rotating at the end of the adjusting screw 217 away from the crank handle 216.

[0044] As a preferred implementation, the drive motor 211 drives the drive wheel 212 to rotate, and the sanding belt 214 rotates between the drive wheel 212 and the tension wheel 213. The position of the tension wheel 213 is adjusted by the crank handle 216 and the adjusting screw 217 to keep the sanding belt 214 under appropriate tension, ensuring that the sanding belt 214 runs stably and adapts to different grinding needs.

[0045] Specifically, the clamping assembly 45 includes: a knob 451 located on the outside of the clamping sliding block 42 near the push rod 41; a rotating threaded rod 452 disposed and rotated inside the clamping sliding block 42, with one end extending and connected to the knob 451; a part placement groove 453 formed on the clamping sliding block 42; and a clamping block 454 sliding inside the part placement groove 453, with one end threadedly connected to the rotating threaded rod 452.

[0046] In this embodiment, rotating the knob 451 causes the rotating threaded rod 452 to rotate, and the clamping block 454 slides in the part placement groove 453 to clamp or release the part, thereby achieving stable clamping of the part and adapting to parts of different shapes.

[0047] Example 2:

[0048] Based on Example 1, the user then starts the stepper motor 31. The output end of the stepper motor 31 drives the double threaded screw 32 to rotate. The sliding block 33 slides to both sides on the bottom platform 11. The support rod 35 changes angle along the hinge point to lift the lifting platform 34. At the same time, the telescopic column 36 extends and retracts upward to provide auxiliary support until the surface of the part contacts the sanding belt 214 to polish the surface. At this time, the user slowly pushes the push rod 41. Under the action of the slider 44 sliding inside the slide groove 43, it clamps the sliding block 42 and moves it to the side of the sanding belt 214 to polish the surface of the part. When polishing the raised arc surface of the part, the protrusion of the part applies pressure to the surface of the sanding belt 214. The telescopic wheel 221 inside the sanding belt 214 is pressed and moves to the lower surface of the top platform 12. At the same time, the telescopic spring 223 tightens, the telescopic rod 224 retracts, and the sanding belt 214 deforms inward at the raised part of the part to adapt to the raised surface of the part.

[0049] Specifically, the lifting assembly 3 includes: a stepper motor 31, disposed at one end of the bottom platform 11; a double-threaded screw 32, rotating inside the bottom platform 11, with one end connected to the output end of the stepper motor 31; two sets of sliding blocks 33, threadedly connected to both ends of the double-threaded screw 32; a lifting platform 34, disposed on the bottom platform 11; four sets of support rods 35, with one end hinged to the upper surface of one side of the sliding block 33 and the other end hinged to the lower surface of the lifting platform 34; and four sets of telescopic columns 36, with one end connected to the upper surface of the bottom platform 11 and the other end connected to the lower surface of the lifting platform 34.

[0050] With this configuration, the stepper motor 31 drives the double-threaded screw 32 to rotate, the sliding block 33 moves along the screw, causing the lifting platform 34 to move up and down, and the telescopic column 36 extends and retracts to support the lifting platform 34. Effect: Enables height adjustment of parts to adapt to different grinding positions.

[0051] Specifically, the adaptive vertical assembly 22 includes: a telescopic wheel 221, which is arranged at the bottom of the top platform 12 and located inside the sanding belt 214, with its bottom surface in contact with the inner ring of the sanding belt 214; a telescopic block 222, which is arranged on both sides of the telescopic wheel 221; a telescopic spring 223, which is fixedly connected at one end to the telescopic block 222 and at the other end to the bottom of the top platform 12; and a telescopic rod 224, which is fixedly connected at one end to the telescopic block 222 and at the other end to the bottom of the top platform 12, and is arranged inside the telescopic spring 223.

[0052] In this embodiment, the telescopic spring 223 and the telescopic rod 224 automatically adjust the position of the telescopic wheel 221 according to the change in the height of the part, so that the sanding belt 214 adapts to the up and down movement of the part, thereby improving the adaptability and flexibility of sanding.

[0053] Example 3:

[0054] Based on Example 2, when the sanding belt 214 is loose and needs to be tightened, the user rotates the locking nut 218 to engage the adjusting screw 217, and then rotates the crank handle 216. The adjusting screw 217 rotates and engages the sliding shaft 215. The sliding shaft 215 slides to one side and drives the tensioning wheel 213 to move until the tightness of the sanding belt 214 is adjusted to a suitable tightness.

[0055] In actual use, the parts need to be polished and placed inside the parts placement slot 453. The user rotates the knob 451, rotates the threaded rod 452, and rotates the clamping block 454 to move towards the parts and clamp them. Then the user starts the drive motor 211. The output end of the drive motor 211 drives the drive wheel 212 to rotate. The drive wheel 212 drives the outer sanding belt 214 and the tensioning wheel 213 to rotate. The user then starts the stepper motor 31. The output of the stepper motor 31 drives the double-threaded screw 32 to rotate. The sliding block 33 slides to both sides on the bottom platform 11. The support rod 35 changes angle along the hinge point to lift the lifting platform 34. At the same time, the telescopic column 36 extends and retracts upward to provide auxiliary support until the surface of the part contacts the sanding belt 214 to polish the surface. At this time, the user slowly pushes the push rod 41. The slider 44 slides inside the slide groove 43 and clamps the sliding block 42 to move to one side of the sanding belt 214 to polish the surface of the part. When polishing the raised arc surface of the part, the protrusion of the part applies pressure to the surface of the sanding belt 214. The telescopic wheel 221 inside the sanding belt 214 is pressed and moves to the lower surface of the top platform 12. At the same time, the telescopic spring 223 tightens and the telescopic rod 224 retracts. The sanding belt 214 deforms inward at the raised part of the part to adapt to the raised surface of the part. When the sanding belt 214 is loose and needs to be tightened, the user rotates the locking nut 218 to engage the adjusting screw 217, and then rotates the crank handle 216. The adjusting screw 217 rotates and engages the sliding shaft 215. The sliding shaft 215 slides to one side and drives the tensioning wheel 213 to move until the tension of the sanding belt 214 is adjusted to a suitable tightness.
