Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a polishing device capable of preventing excessive grinding damage to the exterior of a workpiece. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. During the production process of bicycle parts, particles, scale and burrs will be produced on the surface. Polishing equipment is needed to process the surface of the parts to reduce the surface roughness of the parts, remove defects, change the surface gloss of the parts, and make the surface smooth and flat. The dust and fine debris generated by existing polishing equipment during the polishing process can cause harm to the human body, and large debris cannot be recycled; the fixture style of the polishing equipment is single, and it cannot take into account parts of different sizes and shapes, which will cause unstable clamping. At the same time, the clamping force cannot be observed in real time. Excessive clamping force will cause damage to fragile parts, which is inconvenient for workers to use. Summary of the invention

A polishing wheel structure is installed above the support plate, and a touch screen structure is installed above the support plate near the edge. After the three-stage fixture structure is adjusted to clamp the parts by controlling the telescopic structure through the touch screen, the polishing wheel structure is controlled to make the polishing wheel reach a suitable height and angle, and the three-stage fixture structure and the polishing wheel are adjusted according to the pressure displayed on the touch screen. During the polishing process, harmful fines are treated by the dust absorption and filtering structure.

[0005] The polishing wheel structure includes a motor, a mechanical arm, a polishing wheel and a first pressure sensor. The motor is connected to a control system through a circuit. The motor is installed on one side of the mechanical arm, the polishing wheel is installed under the mechanical arm, and the first pressure sensor is installed inside the polishing wheel. The motor is controlled by a touch screen, and the motor controls the mechanical arm to adjust the polishing wheel to a suitable height and angle to process bicycle parts.

[0047] Working principle of the present invention:

[0048] During operation, the operator places the bicycle parts between the three-section clamp structure 7, and selects the corresponding clamp according to the size and shape of the parts. When clamping, the second pressure sensor 706 is pressed into groove one by the reset spring 710. For example, when clamping a small part 701, the operator operates the touch screen 1002, and the control system energizes the spring 708 according to the signal fed back by the touch screen 1002. After being energized, the spring 708 shrinks and drives the locking block to retract into groove two. At the same time, the operator controls the second retraction motor 6 through the touch screen 1002 to retract the medium-sized splint 702 along the helical toothed guide rail 704, and then controls the first telescopic structure 5 to make the small splint 701 clamp the parts; if the medium-sized splint 702 is needed, the operator controls the second telescopic structure 6 through the touch screen to push the medium-sized splint 702 to the baffle 705 along the helical toothed guide rail 704 to fix it, and then the operator controls the first telescopic structure 5 to make the combination of the small splint 701 and the medium-sized splint 702 When a large clamp 703 is needed, the operator controls the second telescopic structure 6 through the touch screen to push the large clamp 703 to the baffle 705 along the helical toothed guide rail 704 to fix it, and then controls the second telescopic structure 6 to push the medium clamp 702 to the baffle 705 along the helical toothed guide rail 704 to fix it, and then controls the first telescopic structure 5 through the touch screen to make the combined clamp of the small clamp 701, the medium clamp 702 and the large clamp 703 clamp the part. When the three-stage clamp structure 7 clamps the part, the second pressure sensor 706 inside will reflect the pressure on the touch screen 1002 in real time, and the operator can control the first telescopic structure 5 through the control screen to adjust the position of the three-stage clamp structure 7 so that the pressure is in a state of clamping the part without damaging the part.

[0049] After clamping the parts, the operator controls the mechanical arm 902 through the touch screen to adjust the polishing wheel 903 to a suitable height and angle to process the bicycle parts. During processing, the first pressure sensor 904 inside the polishing wheel 903 will sense the pressure changes in real time. When the pressure decreases, the rotating motor 4 will drive the first telescopic structure 5 to rotate, and the first telescopic structure 5 will promptly drive the three-stage clamp structure 7 to rotate, so that over-polishing will not occur, and excessive polishing of the parts' exterior can be prevented.

[0050] Harmful substances such as dust and fine debris generated by the polishing equipment during the polishing process will be absorbed by the fan 803 through the hose 802 into the filter box 804, and after passing through the filter 806, they will be discharged through the air outlet hole 805, and the fine debris will remain in the filter box 804; the large debris generated during the polishing process will be thrown onto the protective cover 801, and after losing power, it will fall downward into the recovery tank 2 under the action of gravity, thereby realizing the filtering and recovery of the debris generated during the polishing process.

[0051] After the work is finished, the operator controls the robot arm 902 through the touch screen 1002 to retract the polishing wheel 903, and then controls the first retracting structure 5 to retract the three-stage clamp structure 7 to release the parts.
