Description

Technical Field

[0001] The invention belongs to the technical field of star-shaped sleeve loading and unloading, and specifically refers to a star-shaped sleeve loading and unloading device. Background Art

[0002] The star-shaped sleeve is a workpiece with a special shape. In order to obtain a star-shaped sleeve with a precise shape and surface roughness, a special grinding device is required to grind it. The current method of processing the star-shaped sleeve is to manually place the star-shaped sleeve on the workpiece chuck and clamp the star-shaped sleeve. When the grinding is completed, the workpiece chuck is loosened, and then the star-shaped sleeve is manually removed. The star-shaped sleeve blank needs to be placed back and forth, which is more troublesome. The existing loading and unloading device does not have the ability to grind the star-shaped sleeve, and can only simply load and unload the star-shaped sleeve. The use function is single, and therefore, it cannot meet the use requirements of the existing loading and unloading device for the star-shaped sleeve. Summary of the invention

[0006] When in use, rotate the locking nut, the locking nut is unscrewed from the outside of the serial shaft, the serial shaft is pulled out of the loading shaft and the sliding frame, and multiple sets of star-shaped sleeves are inserted into the outside of the loading shaft. The star-shaped sleeves are placed on the load-bearing rod. The serial shaft passes through the loading shaft and the sliding frame, and the locking nuts are screwed into both ends of the loading shaft. In the initial state, the lifting frame is located at the end of the sliding frame close to the base, and the fixed electromagnet is energized to generate magnetism. The fixed electromagnet at the bottom of the sliding frame is set with the same pole as the lifting magnet, and the fixed electromagnet on the top of the sliding frame is set with the opposite pole to the lifting magnet. Under the action of the magnetic field between the fixed electromagnets and the lifting magnets at both ends of the sliding frame, the lifting frame slides and rises along the sliding frame, and the clamping spring is set to be shortened. The lifting frame drives the star-shaped clamping plate to rise to the level of the star-shaped sleeve at one end of the loading shaft close to the load-bearing rod. The driving and clamping electromagnet is energized to generate magnetism. The driving and clamping electromagnet and the clamping magnet are arranged with the same pole. The driving and clamping electromagnet is fixed on the inner wall of the lifting frame and pushes the clamping magnet under the deformation of the clamping spring. The clamping magnet drives the star-shaped clamping plate to move relative to each other through the clamping rod. The star-shaped teeth on the surface of the star-shaped clamping plate enter the tooth grooves on the surface of the star-shaped sleeve to complete the clamping operation of the star-shaped sleeve. The magnetic poles of the fixed electromagnets at both ends of the sliding frame change, and the lifting frame descends under the action of the magnetic field between the fixed electromagnet and the lifting magnet. The star-shaped sleeve clamped between the star-shaped clamping plates moves away from the outside of the loading shaft under the deformation of the bearing spring. When the clamped star-shaped sleeve is separated from the bearing spring and the bearing rod, the bearing spring elastically resets to support and block the star-shaped sleeve above the clamped star-shaped sleeve to complete the feeding operation of the star-shaped sleeve.

[0007] Preferably, the grinding body mechanism includes an abrasive tube shaft, a partition plate, a sliding sleeve, an airbag, an elastic grinding layer, a support spring and a pitch-adjusting screw block. The abrasive tube shaft passes through the base and is rotatably arranged on the bottom wall of the loading shaft. The partition plate is arranged in the middle part of the abrasive tube shaft. The sliding sleeve is symmetrically arranged on the outside of the abrasive tube shaft on both sides of the partition plate. The sliding sleeve is slidably arranged on the outside of the abrasive tube shaft. The support spring is arranged between the sliding sleeve and the partition plate on the outside of the abrasive tube shaft. The pitch-adjusting screw block is arranged on the outside of the abrasive tube shaft on one side of the sliding sleeve. The pitch-adjusting screw block is threadedly connected to the abrasive tube shaft. The airbag is arranged between the partition plate on the outside of the abrasive tube shaft and the side wall of the loading mechanism. Multiple groups of elastic grinding layers are arranged on the outside of the airbag; the inflation mechanism includes an inflation pump and an inflation port. The inflation pump is arranged on the bottom wall of the base. The inflation end of the inflation pump passes through the inner wall of the base. The inflation end inflation pump is in contact with the abrasive tube shaft, and the inflation port is arranged on the side walls of the abrasive tube shaft on both sides of the partition plate.

[0008] When in use, the pitch-adjusting screw block is rotated, and the pitch-adjusting screw block rotates along the axial direction of the abrasive tube away from the partition plate. There is a distance between the pitch-adjusting screw block and the sliding sleeve. The supporting spring is fixed on the side wall of the partition plate and pushes the sliding sleeve to slide toward the end of the abrasive tube axis close to the pitch-adjusting screw block through elastic force. The length of the airbag is extended, the working area of ​​the elastic grinding layer is increased, and the grinding time of the inner wall of the star-shaped sleeve is prolonged. As the grinding time of the elastic grinding layer on the inner wall of the star-shaped sleeve increases, the debris gathered between the elastic grinding layer and the inner wall of the star-shaped sleeve gradually increases. The increase in debris will increase the friction and heat in the grinding process, resulting in The wall becomes rough and the surface roughness increases. Therefore, when the elastic grinding layer grinds the inner wall of the star-shaped sleeve, the lifting frame continuously descends under the action of the magnetic field of the fixed electromagnet and the lifting magnet until the star-shaped sleeve is completely separated from the outer side of the elastic grinding layer. The elastic grinding layer after grinding the inner wall of the star-shaped sleeve is exposed to the outside as the lifting frame descends. The chip-absorbing magnet absorbs the iron chips remaining on the surface of the elastic grinding layer, the driving electromagnet is powered off and demagnetized, and the clamping spring elastically resets to drive the star-shaped clamping plates to move in opposite directions through the clamping rod. The ground star-shaped sleeve falls onto the base, completing the unloading operation of the star-shaped sleeve.

[0009] Specifically, the snap-fit ​​driving mechanism includes a driving groove, a driving block, a three-phase coil, a polygonal groove, a polygonal block, a driving magnet and a loading plate. The driving groove is arranged on the upper wall of the base, and the driving groove is opened at the upper end. The driving block is rotatably arranged on the bottom wall of the driving groove outside the abrasive tube axis. The three-phase coil is arranged on the outside of the driving block. The polygonal groove is arranged on the upper wall of the driving block. The driving block is opened at the upper end. The polygonal block is arranged at one end of the abrasive tube axis close to the polygonal groove. The polygonal block is snap-fitted inside the polygonal groove. Multiple groups of driving magnets are arranged on the inner wall of the driving groove. The three-phase coil and the driving magnet are arranged opposite to each other. Multiple groups of loading plates are arranged on the bottom wall of the base above the driving groove.

[0010] When in use, the abrasive tube shaft is inserted into the polygonal groove through the polygonal block, the abrasive tube shaft fits against the inflation end of the air pump, the air pump transports gas to the inside of the abrasive tube shaft through the inflation end, the gas inside the abrasive tube shaft enters into the airbag through the inflation port, the airbag swells up due to the deformation of the elastic grinding layer, when the lifting frame drives the star-shaped clamping plate to be level with the star-shaped sleeve on the outside of the material-carrying shaft near one end of the airbag, the air pump extracts the gas inside the airbag through the inflation end, the air pressure inside the airbag is reduced, and the diameter of the airbag is shortened, which makes it easier for the star-shaped clamping plate to drive the star-shaped sleeve to be inserted into the outside of the airbag. When the star-shaped clamping plate drives the star-shaped sleeve to enter the outside of the airbag, the air pump uses the inflation end to pass through the abrasive The airbag is filled with gas along the axis of the tube, and the airbag drives the elastic grinding layer to fit the inner wall of the star-shaped sleeve. The air pump continuously extracts and replaces the gas inside the airbag, which can prevent the gas inside the airbag from having a high temperature due to the grinding operation time being too long. The three-phase coil is energized and a magnetic field is generated between the driving magnet. The driving block rotates under the action of the three-phase coil and the driving magnet magnetic field. The driving block drives the polygonal block to rotate through the polygonal groove. The polygonal block drives the sliding sleeve and the partition plate to rotate through the abrasive tube axis. The partition plate and the sliding sleeve drive the elastic grinding layer through the airbag to grind the inner wall of the star-shaped sleeve. The ground star-shaped sleeve falls to the upper wall of the loading plate and is placed.

[0011] The beneficial effects achieved by adopting the above structure are as follows:

[0012] Compared with the prior art, the present invention adopts a combination of a vertical guiding structure and a segmented action structure. Through the provision of a clamping and conveying integrated material transport mechanism, an extended grinding mechanism and a snap-on driving mechanism, under the cooperation of the lifting mechanism, the clamping mechanism, the loading mechanism, the grinding body mechanism and the inflation mechanism, the grinding time of the star-shaped sleeve can be prolonged, and a large amount of debris accumulated between the inner wall of the star-shaped sleeve and the elastic grinding layer can be avoided, thereby ensuring the grinding quality of the star-shaped sleeve. With the support of the chip-absorbing magnet, the centrifugal force of the rotational force of the elastic grinding layer driven by the airbag is enhanced, thereby improving the cleaning force of the residual debris on the surface of the elastic grinding layer. At the same time, under the alternating operation of the air pump for exhausting and inflating, the gas inside the airbag can be replaced in time to avoid excessive temperature of the gas inside the airbag. By providing a loading shaft and a loading plate , the star-shaped sleeve is loaded and unloaded, and the gas inside the abrasive tube shaft enters the airbag through the inflation port, and the airbag swells up by the deformation of the elastic grinding layer. When the lifting frame drives the star-shaped clamping plate to be level with the star-shaped sleeve on the outside of the loading shaft near one end of the airbag, the inflation pump extracts the gas inside the airbag through the inflation end, and the air pressure inside the airbag is reduced, and the diameter of the airbag is shortened, which is convenient for the star-shaped clamping plate to drive the star-shaped sleeve to be inserted into the outside of the airbag. When the star-shaped clamping plate drives the star-shaped sleeve to enter the outside of the airbag, the inflation pump uses the inflation end to fill the airbag with gas through the abrasive tube shaft, and the airbag drives the elastic grinding layer to fit the inner wall of the star-shaped sleeve. Under the action of the inflation pump constantly extracting and replacing the gas inside the airbag, it can avoid the gas inside the airbag from having a high temperature due to the grinding operation time being too long.

The drive slot 31 is arranged on the upper wall of the base 1, and the drive slot 31 is opened at the upper end.

Multiple groups of carrier plates 37 are arranged on the bottom wall of the base 1 above the drive slot 31.

[0034] When in use, the locking nut 19 is rotated, and the locking nut 19 is unscrewed from the outside of the serial shaft 18, and the serial shaft 18 is pulled out of the loading shaft 15 and the sliding frame 2, and multiple sets of star sleeves are inserted into the outside of the loading shaft 15, and the star sleeves are placed on the bearing rod 17. The serial shaft 18 passes through the loading shaft 15 and the sliding frame 2, and the locking nut 19 is screwed into both ends of the loading shaft 15. The abrasive tube shaft 22 is inserted into the polygonal groove 34 through the polygonal block 35, and the abrasive tube shaft 22 is fitted with the inflation end of the inflation pump 28;

[0035] In the initial state, the lifting frame 6 is located at one end of the sliding frame 2 close to the base 1, and the fixed electromagnet 5 is energized to generate magnetism. The fixed electromagnet 5 at the bottom of the sliding frame 2 is set with the same pole as the lifting magnet 7, and the fixed electromagnet 5 at the top of the sliding frame 2 is set with the lifting magnet 7 with different poles. Under the action of the magnetic field between the fixed electromagnet 5 and the lifting magnet 7 at both ends of the sliding frame 2, the lifting frame 6 slides and rises along the sliding frame 2, and the clamping spring 10 is shortened. The lifting frame 6 drives the star-shaped clamping plate 38 to rise to The driving and clamping electromagnet 11 is energized to generate magnetism at one end of the star-shaped sleeve near the load-bearing rod 17 of the loading shaft 15. The driving and clamping electromagnet 11 and the clamping magnet 12 are arranged with the same pole. The driving and clamping electromagnet 11 is fixed to the inner wall of the lifting frame 6 and pushes the clamping magnet 12 under the deformation of the clamping spring 10. The clamping magnet 12 drives the star-shaped clamping plate 38 to move relative to each other through the clamping rod 9. The star-shaped teeth on the surface of the star-shaped clamping plate 38 enter the tooth grooves on the surface of the star-shaped sleeve to complete the clamping operation of the star-shaped sleeve.

[0036] The magnetic poles of the fixed electromagnets 5 at both ends of the sliding frame 2 change, and the lifting frame 6 descends under the action of the magnetic field between the fixed electromagnets 5 and the lifting magnets 7. The star-shaped sleeve clamped between the star-shaped clamping plates 38 moves away from the outside of the loading shaft 15 under the deformation of the bearing spring 16. When the clamped star-shaped sleeve is separated from the bearing spring 16 and the bearing rod 17, the bearing spring 16 elastically resets to support and block the star-shaped sleeve above the clamped star-shaped sleeve, thereby completing the feeding operation of the star-shaped sleeve;

[0037] According to user needs, the working area of ​​the airbag 25 and the elastic grinding layer 26 is adjusted, and the pitch-adjusting screw block 40 is rotated. The pitch-adjusting screw block 40 rotates along the abrasive tube axis 22 toward the end away from the partition plate 23. There is a distance between the pitch-adjusting screw block 40 and the sliding sleeve 24. The support spring 39 is fixed on the side wall of the partition plate 23 and pushes the sliding sleeve 24 to slide toward the end of the abrasive tube axis 22 close to the pitch-adjusting screw block 40 through elastic force. The length of the airbag 25 is extended, the working area of ​​the elastic grinding layer 26 is increased, and the grinding time of the inner wall of the star-shaped sleeve is extended. The air pump 28 delivers gas to the inside of the abrasive tube axis 22 through the inflation end, and the gas inside the abrasive tube axis 22 enters the inside of the airbag 25 through the inflation port 29. The airbag 25 bulges by the deformation of the elastic grinding layer 26. When the lifting frame 6 When the star-shaped clamping plate 38 is driven to be level with the star-shaped sleeve on the outside of the material-carrying shaft 15 near one end of the airbag 25, the air pump 28 extracts the gas inside the airbag 25 through the inflation end, the air pressure inside the airbag 25 is reduced, and the diameter of the airbag 25 is shortened, so that the star-shaped clamping plate 38 drives the star-shaped sleeve to be inserted into the outside of the airbag 25. When the star-shaped clamping plate 38 drives the star-shaped sleeve to enter the outside of the airbag 25, the air pump 28 uses the inflation end to fill the air into the airbag 25 through the abrasive tube shaft 22, and the airbag 25 drives the elastic grinding layer 26 to fit with the inner wall of the star-shaped sleeve. Under the action of the air pump 28 constantly extracting and replacing the gas inside the airbag 25, it can avoid the situation where the gas inside the airbag 25 has a high temperature due to the long grinding operation time;

[0038] When the three-phase coil 33 is energized, a magnetic field is generated between the three-phase coil 33 and the driving magnet 36. The driving block 32 rotates under the action of the magnetic field of the three-phase coil 33 and the driving magnet 36. The driving block 32 drives the polygonal block 35 to rotate through the polygonal groove 34. The polygonal block 35 drives the sliding sleeve 24 and the partition plate 23 to rotate through the abrasive tube shaft 22. The partition plate 23 and the sliding sleeve 24 drive the elastic grinding layer 26 to grind the inner wall of the star-shaped sleeve through the airbag 25. As the grinding time of the elastic grinding layer 26 on the inner wall of the star-shaped sleeve increases, the debris gathered between the elastic grinding layer 26 and the inner wall of the star-shaped sleeve gradually increases. The increase in debris will increase the friction and heat in the grinding process, causing the inner wall of the star-shaped sleeve to become rough and the surface roughness to increase.

[0039] Therefore, when the elastic grinding layer 26 grinds the inner wall of the star-shaped sleeve, the lifting frame 6 continuously descends under the action of the magnetic fields of the fixed electromagnet 5 and the lifting magnet 7 until the star-shaped sleeve is completely separated from the outer side of the elastic grinding layer 26. The elastic grinding layer 26 after grinding the inner wall of the star-shaped sleeve is exposed to the outside world as the lifting frame 6 descends. The chip-absorbing magnet 13 absorbs the iron chips remaining on the surface of the elastic grinding layer 26, thereby enhancing the centrifugal force of the elastic grinding layer 26 on the residual chips on the surface when the elastic grinding layer 26 rotates. The driving electromagnet 11 is powered off and demagnetized, and the clamping spring 10 elastically resets and drives the star-shaped clamping plate 38 to move in opposite directions through the clamping rod 9. The ground star-shaped sleeve falls to the upper wall of the carrier plate 37 for placement, thereby completing the unloading operation of the star-shaped sleeve.

[0040] When the star-shaped sleeve on the outside of the loading shaft 15 has been completely polished, it is necessary to take the star-shaped sleeve placed on the upper wall of the loading plate 37 out of the outside of the abrasive tube shaft 22, and the air pump 28 extracts the gas inside the airbag 25 through the inflation end. The lifting frame 6 drives the star-shaped clamping plate 38 and the partition plate 23 to be placed horizontally under the action of the magnetic field of the fixed electromagnet 5 and the lifting magnet 7. The driving electromagnet 11 pushes the clamping magnet 12 through the repulsive force, and the clamping magnet 12 drives the star-shaped clamping plate 38 to clamp the partition plate 23 through the clamping rod 9. The locking nut 19 is rotated, and the locking nut 19 is released from the loading rod. The outer side of 17 is unscrewed, and the bearing rod 17 is pulled out between the sliding frame 2 and the loading shaft 15. The fixed electromagnet 5 on the upper part of the sliding frame 2 continues to magnetically adsorb the lifting magnet 7, and the fixed electromagnet 5 at the bottom of the sliding frame 2 pushes the lifting magnet 7 with repulsive force. The lifting frame 6 rises and drives the abrasive tube shaft 22 through the partition plate 23. The abrasive tube shaft 22 drives the polygonal block 35 to be pulled out from the inside of the polygonal groove 34. At this time, a distance is generated between the abrasive tube shaft 22 and the loading plate 37, and the polished star-shaped sleeve is taken out to complete the grinding operation of the star-shaped sleeve; the above operation can be repeated when it is used next time.
