A polishing machine with high processing efficiency

Abstract

This invention discloses a high-efficiency polishing machine, relating to the field of polishing machine technology. The high-efficiency polishing machine includes an adjustable polishing device. Through the adjustable polishing device, the machine sequentially activates a first pneumatic hydraulic cylinder, an air compressor, and a bidirectional motor, causing the bottom of a quarter-circular polishing piece to contact the top of a circular sample. The polishing piece penetrates deep into the inner ring of the circular sample. Activating the air compressor increases gas pressure, pushing a piston that moves the polishing piece outward and presses it against the inner wall of the circular sample. Activating the bidirectional motor allows the quarter-circular polishing piece and the polishing piece to simultaneously polish the top and inner wall of the circular sample, significantly improving work efficiency. An adjustable fixing device keeps the first semi-circular ring stationary while the second semi-circular ring continuously approaches and presses against the circular sample between them, preventing the circular sample from moving during subsequent polishing processes.

Description

Technical Field

[0001] This invention relates to the field of polishing machine technology, specifically to a polishing machine with high processing efficiency. Background Technology

[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, friction is applied to the surface to be polished, thereby removing paint contaminants, oxide layers, and shallow scratches. The polishing disc's rotation speed is generally between 1500-3000 rpm, and is mostly continuously variable, allowing for adjustment as needed during operation.

[0003] When polishing ring samples, most polishing machines on the market need to polish both the outer and inner surfaces of the ring. Most polishing machines polish them sequentially, which is time-consuming and labor-intensive. Some polishing machines can polish them simultaneously, but the size of the polishing discs cannot be adjusted, and they can only be used for ring samples of one size, resulting in poor comprehensiveness.

[0014] This invention provides a polishing machine with high processing efficiency. It has the following beneficial effects:

[0015] (1) This high-efficiency polishing machine, through an adjustable polishing device, sequentially starts the first pneumatic hydraulic cylinder, the air compressor, and the bidirectional motor, so that the bottom of the quarter-circle plate polishing part contacts the top of the ring sample, and the polishing part penetrates into the inner ring of the ring sample. The air compressor is started, and the increase in gas pressure pushes the piston. The piston moves the polishing part outward and presses the inner wall of the ring sample. The bidirectional motor is started, and the quarter-circle plate polishing part and the polishing part polish the top and inner wall of the ring sample at the same time, which greatly improves the working efficiency.

[0016] (2) This high-efficiency polishing machine, through an adaptive polishing mechanism, allows compressed gas to enter the piston through the air pipe, the air passage opened in the rotating shaft, the upper hole, the lower hole, the air pipe, the air hole, the connecting pipe, and the air inlet in sequence. At this time, the squeezing force on the side of the piston near the air pipe is greater than the elastic force of the second spring. The piston slides along the guide rail formed by the guide rod and the bottom wall of the fixed part. The piston moves away from the air pipe along the arc plate, the polished part, and the elastic connecting pipe. The second spring is compressed and the elastic connecting pipe is stretched. Finally, the outer side of the polished part contacts the inner wall of the ring sample. No manual adjustment is required. It can adapt to rings with different inner ring sizes, has strong adaptability, and is time-saving and labor-saving to adjust.

[0017] (3) This high-efficiency polishing machine, through an adjustable fixing device, keeps the first semi-circular ring stationary, reduces the distance between the second semi-circular ring and the first semi-circular ring, and the first extrusion arc plate and the second extrusion arc plate also move closer to the side of the lower part of the circular ring sample. The first semi-circular ring is provided with three first extrusion arc plates, and the second semi-circular ring is provided with two second extrusion arc plates. The circular ring sample squeezes the first extrusion arc plate, the second extrusion arc plate and the first spring in sequence. The first spring is compressed, and the inner sides of the five extrusion arc plates are provided with vertical grooves and horizontal grooves to increase friction and prevent the circular ring sample from moving during the subsequent polishing process.

[0018] (4) This high-efficiency polishing machine, through an adjustable fixing device and an adjustable polishing device, places the ring sample into the first semi-circular ring and the second semi-circular ring. Through the elastic action of the first spring and the rough surface of the extrusion arc plate, the ring sample is pressed. The adjustable polishing device polishes the top and inner wall of the ring sample at the same time. The ring sample is subjected to a large outward centrifugal force. The adjustable fixing device can ensure that the ring sample remains stationary. Both devices are operated automatically, saving time and effort. Attached Figure Description

An air compressor 74 is fixedly connected to the top of the micro powder suspension storage box 73. An air pipe 75 is connected to the top of the air compressor 74.

[0041] The adaptive polishing mechanism 78 includes a quarter-circle polishing component 781. The top of the quarter-circle polishing component 781 is fixedly connected to the bottom of the fixing component 77. There are four quarter-circle polishing components 781 in total, which are equidistantly distributed in the circumferential direction of the fixing component 77. A rectangular fixing plate 782 and two guide rods 783 are provided between two adjacent quarter-circle polishing components 781. The two sides of the rectangular fixing plate 782 are fixedly connected to the side of the two quarter-circle polishing components 781 that are close to each other. The side of the rectangular fixing plate 782 that is close to the axis of the fixing component 77 is fixedly connected to the side of the guide rod 783 that is away from the axis of the fixing component 77. The side of the two guide rods 783 that is away from each other is fixedly connected to the side of the two adjacent quarter-circle polishing components 781 that are close to each other.

[0042] The radius-adjustable polishing component 784 includes a connecting pipe 7841, which is connected to the vent pipe 18. An arc-shaped plate 7844 is provided at the end of the connecting pipe 7841 away from the vent pipe 18. An air inlet 7843 is provided through the arc-shaped plate 7844. The air inlet 7843 is connected to the end of the connecting pipe 7841 away from the vent pipe 18. A piston component 7842 is connected to the side of the air inlet 7843 away from the vent pipe 18. A second spring 7846 is fixedly connected to the side of the piston component 7842 away from the vent pipe 18.

There are four polishing components 7845, which are equidistantly distributed along the circumference of the vent pipe 18.

[0043] In use, the first semi-circular ring 611 and the second semi-circular ring 626 are open. The circular ring sample 9 is placed inside, and the first semi-circular ring 611 is fixed. The second pneumatic hydraulic pump 622 is started, and the piston rod 623 of the second pneumatic hydraulic pump 622 extends forward. The piston rod 623 moves the rotating ring 624, the fixed arm 625, and the second semi-circular ring 626 in sequence. The fixed arm 625 and the rotating plate 628 rotate around the rotating ring 624 and the fixed rod 619, respectively. The second semi-circular ring 626 continuously approaches the first semi-circular ring 611, and the distance between the second semi-circular ring 626 and the first semi-circular ring 611 decreases.

Finally, the locking rod 627 is locked into the locking groove 617, so that the first semicircular ring 611 and the second semicircular ring 626 are closed more tightly and are not easy to move. In addition, the inner sides of the five extrusion arc plates are provided with vertical grooves 12 and horizontal grooves 13 to increase friction and prevent the ring sample 9 from moving during the subsequent polishing process.

[0044] Next, the first pneumatic-hydraulic cylinder 1 is activated. The piston rod of the first pneumatic-hydraulic cylinder 1 moves the bidirectional motor 71, the quarter-circle polishing part 781, and the polishing part 7845 downwards. The bottom of the quarter-circle polishing part 781 contacts the top of the annular sample 9, and the polishing part 7845 is fully inserted into the inner ring of the annular sample 9. Then, the air compressor 74 is activated. The compressed gas from the air compressor 74 enters the piston part 7842 sequentially through the air pipe 75, the air passage opened in the rotating shaft 72, the upper hole 14, the lower hole 15, the vent pipe 18, the air hole 17, the connecting pipe 7841, and the air inlet 7843. When the squeezing force of the piston 7842 near the vent pipe 18 is greater than the elastic force of the second spring 7846, the piston 7842 slides along the guide rail formed by the guide rod 783 and the bottom wall of the fixing member 77. The piston 7842, along with the arc plate 7844, the polished part 7845, and the elastic connecting tube 7841, moves away from the vent pipe 18. The second spring 7846 is compressed, and the elastic connecting tube 7841 is stretched. Finally, the outer side of the polished part 7845 contacts the inner wall of the ring sample 9. No manual adjustment is required. It can adapt to rings with different inner ring sizes, has strong adaptability, and saves time and effort in adjustment.

[0045] Finally, the bidirectional motor 71 is started. The output end of the bidirectional motor 71 sequentially rotates the micro powder suspension storage box 73, the fixing part 77, the quarter-circle plate polishing part 781, the rectangular fixing plate 782, the guide rod 783, the connecting pipe 7841, the piston part 7842, and the polishing part 7845. The quarter-circle plate polishing part 781 and the polishing part 7845 simultaneously polish the top and inner wall of the annular sample 9, greatly improving work efficiency.
