[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention sets a control device. When the equipment is in use, the fixing ring is fixed to the outside of the machine body, and the telescopic rod on the top of the fixing ring is extended under the control of the hydraulic system. The telescopic rod lifts the top plate upward, and the sealing ring is separated from the upper surface of the machine body. During this process, non-standard workpieces are stored inside the storage plate. Under the action of gravity and the pressure of the workpiece, the baffle falls, the limit rod moves downward, and the workpiece on the outer surface of the conical block slides downward under the action of gravity, and then falls from the through groove in the baffle wall to the inside of the machine body. The falling of the workpiece is automatically controlled by the telescopic rod, so that the workpiece inside the machine body does not need to be manually fed, which solves the problem that the feed amount of traditional polishing equipment cannot be controlled and the inside of the equipment is easy to be blocked.

[0016] 2. The present invention provides a polishing device. When the equipment is in use, the workpiece enters the interior of the machine body, and the discharge pipe sprays sand into the interior of the hollow ring. The high-speed splashing sand is sprayed from the circular hole in the hollow ring wall to the interior of the machine body, and the sand contacts the workpiece. The protrusions on the outer surface of the workpiece are impacted and removed by the high-speed sand. The fine sand achieves a polishing effect. After the sandblasting is completed, the pin is pulled out, and the retaining ring is pushed downward along the outer surface of the machine body. The through groove on the side wall of the machine body is opened, and the workpiece is taken out. The polished debris is discharged from the debris pipe to the outside of the machine body, and the air exchange hole performs air flow exchange, which solves the problem of direct grinding of traditional polishing equipment, limited polishing surface and poor polishing effect.

[0017] 3. The present invention is provided with a cyclone device. When the equipment is in use, the shaft rotates driven by an external motor, and high-pressure air is injected into the interior of the shaft from the air injection pipe at the bottom end of the shaft. Since the through hole opening in the shaft wall is inclined downward and the shaft rotates at a high speed, the high-pressure airflow carries sand and gravel to impact the outer surface of the workpiece. The workpiece is continuously turned over under the impact of the airflow, so that each surface of the workpiece can be polished. The number of openings of the through hole is controlled by the adjusting rod, thereby controlling the air pressure and flow rate of the injection. After the sandblasting and the workpiece polishing are completed, the sandblasting and debris fall from the leak plate, the workpiece is discharged from the through groove on the side wall of the machine body, the sandblasting and debris fall into the interior of the sieve plate, and the sieve plate rotates with the shaft. Inside the sieve plate, the sand and debris are separated, the debris has a small diameter and falls downward, the sand and gravel are sucked into the bent pipe, and the fallen debris is discharged from the debris pipe. When the sealing ring contacts and seals with the upper surface of the machine body, the outer surface of the ball rotates with the lower surface of the top plate, reducing the resistance when the shaft rotates, solving the problem that the debris is easily scattered in the traditional polishing equipment.

[0018] 4. The present invention provides a suction device. When the equipment is in use, the piston sucks upward, and the bent pipe sucks through negative pressure to suck the gravel inside the screen plate into the inside of the sealing tube. The gravel fills the space at the bottom of the piston. Then the piston is squeezed downward, and the fine gravel at the bottom of the piston pushes up the cover plate and the connecting rod through the circular hole of the piston, and the gravel enters the top of the piston. Then the piston is pulled upward, and the gravel is squeezed into the inside of the machine body from the discharge pipe under the action of pressure, thereby realizing the circulation of the gravel. The equipment realizes self-circulating multi-stage polishing, which solves the problem that traditional polishing equipment requires continuous addition of gravel and has poor polishing effect.

[0033] When in use, the fixing ring 10 is fixed to the outside of the machine body 20, and the telescopic rod 11 on the top of the fixing ring 10 is extended under the control of the hydraulic system. The telescopic rod 11 pushes the top plate 12 upward, and the sealing ring 17 is separated from the upper surface of the machine body 20. During this process, non-standard workpieces are stored inside the storage plate 13. Under the action of gravity and the pressure of the workpiece, the baffle 15 falls, the limit rod 14 moves downward, and the workpiece on the outer surface of the conical block 16 slides downward under the action of gravity, and then falls from the through groove in the wall of the baffle 15 to the inside of the machine body 20. The falling of the workpiece is automatically controlled by the telescopic rod 11 to avoid the need for manual feeding of the workpiece inside the machine body 20.

[0034] The workpiece enters the interior of the machine body 20, and the discharge pipe 44 sprays the sand into the interior of the hollow ring 21. The high-speed splashing sand is ejected from the circular hole in the wall of the hollow ring 21 to the interior of the machine body 20, and the sand contacts the workpiece. The protrusions on the outer surface of the workpiece are removed by the high-speed sandblasting. The fine sand achieves a polishing effect. After the sandblasting is completed, the pin 24 is pulled out, and the retaining ring 23 is pushed downward along the outer surface of the machine body 20. The through groove on the side wall of the machine body 20 is opened, and the workpiece is taken out. The polished debris is discharged from the debris pipe 25 to the outside of the machine body 20, and the air exchange hole 22 performs air flow exchange.

[0035] The shaft 30 rotates under the drive of the external motor, and high-pressure air is injected into the shaft 30 from the air injection pipe at the bottom of the shaft 30. Since the through hole 32 in the wall of the shaft 30 opens downward and the shaft 30 rotates at a high speed, the high-pressure airflow carries sand and gravel to impact the outer surface of the workpiece. The workpiece is constantly turned over under the impact of the airflow, so that each surface of the workpiece can be polished.

The sandblasting and the chips fall to the inside of the screen plate 35. The screen plate 35 rotates with the shaft 30. Inside the screen plate 35, the sand and chips are separated. The chips are smaller in diameter and fall downward. The sand is sucked into the bend pipe 45, and the fallen chips are discharged from the chip pipe 25.

[0036] The piston 40 sucks upward, and the bent pipe 45 sucks the gravel inside the screen plate 35 into the inside of the sealing tube 43 through negative pressure, and the gravel fills the space at the bottom of the piston 40. Then the piston 40 is squeezed downward, and the fine gravel at the bottom of the piston 40 pushes up the cover plate 42 and the connecting rod 41 through the round hole of the piston 40, and the gravel enters the top of the piston 40. Then the piston 40 is pulled upward, and the gravel is squeezed into the inside of the body 20 from the discharge pipe 44 under the action of pressure, realizing the circulation of the gravel, and the equipment realizes self-circulating multi-stage polishing.

[0037] Working principle:

[0038] When the equipment is in use, the fixing ring 10 is fixed to the outside of the machine body 20, and the telescopic rod 11 on the top of the fixing ring 10 is extended under the control of the hydraulic system. The telescopic rod 11 lifts the top plate 12 upward, and the sealing ring 17 is separated from the upper surface of the machine body 20. During this process, non-standard workpieces are stored inside the storage plate 13. Under the action of gravity and the pressure of the workpiece, the baffle 15 falls, the limit rod 14 moves downward, and the workpiece on the outer surface of the conical block 16 slides downward under the action of gravity, and then falls from the through groove in the wall of the baffle 15 to the inside of the machine body 20. The falling of the workpiece is automatically controlled by the telescopic rod 11, so that the workpiece inside the machine body 20 does not need to be manually fed, which solves the problem that the feed amount of traditional polishing equipment cannot be controlled and the equipment is easily blocked.

[0039] The workpiece enters the interior of the machine body 20, and the discharge pipe 44 sprays the sand into the interior of the hollow ring 21. The high-speed splashing sand is ejected from the circular hole in the wall of the hollow ring 21 to the interior of the machine body 20, and the sand contacts the workpiece. The protrusions on the outer surface of the workpiece are removed by the high-speed sandblasting. The fine sand achieves a polishing effect. After the sandblasting is completed, the pin 24 is pulled out, and the retaining ring 23 is pushed downward along the outer surface of the machine body 20. The through groove on the side wall of the machine body 20 is opened, and the workpiece is taken out. The polished debris is discharged from the debris pipe 25 to the outside of the machine body 20, and the air exchange hole 22 performs air flow exchange, which solves the problem of direct grinding of traditional polishing equipment, limited polishing surface and poor polishing effect.

[0040] The shaft 30 rotates under the drive of the external motor, and high-pressure air is injected into the shaft 30 from the air injection pipe at the bottom of the shaft 30. Since the through hole 32 in the wall of the shaft 30 opens downward and the shaft 30 rotates at a high speed, the high-pressure airflow carries sand and gravel to impact the outer surface of the workpiece. The workpiece is constantly turned over under the impact of the airflow, so that each surface of the workpiece can be polished. The number of openings of the through hole 32 is controlled by the adjustment rod 33, thereby controlling the air pressure and flow rate of the injection. After the sandblasting and workpiece polishing are completed, the sandblasting and debris fall from the leak plate 34, and the workpiece is polished. The sandblasted pieces are discharged from the through grooves on the side walls of the machine body 20, and the sandblasted pieces and the debris fall into the inside of the sieve plate 35. The sieve plate 35 rotates with the shaft 30. Inside the sieve plate 35, the sand and debris are separated. The debris has a smaller diameter and falls downward. The sand is sucked into the curved pipe 45, and the fallen debris is discharged from the debris pipe 25. When the sealing ring 17 contacts and seals with the upper surface of the machine body 20, the outer surface of the ball 31 rotates with the lower surface of the top plate 12, reducing the resistance of the shaft 30 when it rotates, thus solving the problem of easy scattering of debris in traditional polishing equipment.

[0041] The piston 40 draws upward, and the bent pipe 45 draws negative pressure to draw the gravel inside the sieve plate 35 into the interior of the sealing tube 43, and the gravel fills the space at the bottom of the piston 40. Then the piston 40 is squeezed downward, and the fine gravel at the bottom of the piston 40 pushes up the cover plate 42 and the connecting rod 41 through the circular hole of the piston 40, and the gravel enters the top of the piston 40. Then the piston 40 is pulled upward, and the gravel is squeezed into the interior of the body 20 from the discharge pipe 44 under the action of pressure, realizing the circulation of the gravel. The equipment realizes self-circulating multi-stage polishing, which solves the problem that traditional polishing equipment requires continuous addition of gravel and has poor polishing effect.
