[0008] When in use, rotate the locking bolt and the locking bolt is unscrewed from the inside of the rotating block. At this time, the rotating block is in an active state, and the rotating block is driven by the fixed cylinder to rotate around the adjusting column to adjust the inclination angle of the impurity cylinder and the forming cylinder, so as to facilitate the sliding of iron filings generated by the forming cylinder when forming automobile shaft accessories, thereby avoiding iron filings from remaining on the surface of automobile accessories, resulting in reduced processing accuracy and poor surface quality of automobile accessories, thereby ensuring the quality and accuracy of automobile accessories during forming processing.

[0009] Preferably, the guide mechanism includes a guide rod, a push plate, a guide spring and a limit plate, the guide rod is symmetrically arranged at both ends of the fixed cylinder, the guide rod is arranged through both ends of the fixed cylinder, the push plate is arranged on the side of the guide rod away from the fixed cylinder, the guide spring is arranged between the push plate on the outside of the guide rod and the side wall of the fixed cylinder, and the limit plate is arranged on the side of the guide rod away from the push plate; the clamping mechanism includes a drive motor, a drive sleeve, a clamping bolt, an anti-slip pad and a workpiece opening, the drive motor is arranged on the side of the push plate close to the guide rod, the drive sleeve is arranged at the power end of the drive motor, the clamping bolt is symmetrically arranged at the end of the drive sleeve away from the drive motor, the clamping bolt is threadedly connected to the drive sleeve, and the anti-slip pad is arranged close to the clamping bolt On the side close to the driving sleeve, the anti-slip pad is arranged inside the driving sleeve, and the workpiece opening is arranged on the side of the impurity cylinder away from the fixed cylinder; the annular grinding mechanism includes an annular airbag, a sponge grinding sheet, a guide tube and a cold air valve, multiple groups of the annular airbags are arranged on the inner wall of the forming cylinder, the sponge grinding sheet is arranged on the inner wall of the annular airbag, multiple groups of the guide tubes are penetrated and arranged on the side wall of the annular airbag, and the cold air valve is connected and arranged on the side of the forming cylinder away from the fixed cylinder; the pressure sensing mechanism includes a gas pressure sensor and an air pump, multiple groups of the gas pressure sensors are arranged on the inner wall of the forming cylinder, the detection end of the gas pressure sensor is penetrated and arranged on the forming cylinder and the inner wall of the annular airbag, multiple groups of the air pumps are arranged on the side wall of the forming cylinder, and the air inlet end of the air pump penetrates the forming cylinder and is arranged inside the annular airbag.

[0010] When in use, in the initial state, the guide spring is in an extended setting, and a certain distance is maintained between the limit plate and the side wall of the fixed cylinder. Then the push plate is pulled, and the push plate drives the guide rod to slide along the side wall of the fixed cylinder through the deformation of the guide spring. The guide rod drives the limit plate to fit the side wall of the fixed cylinder, and one end of the automobile shaft accessory is placed into the driving sleeve. The clamping bolt is rotated, and the clamping bolt rotates along the driving sleeve to drive the anti-slip pad to fit the automobile shaft accessory. The automobile shaft accessory is fixed inside the driving sleeve. Then the push plate is loosened, and the guide spring elastically resets to drive the other end of the automobile shaft accessory into the workpiece opening. The operator pushes The push plate is driven, and the compression deformation of the guide spring drives the guide rod to slide along the two ends of the fixed cylinder. The impurity cylinder rotates along the fixed cylinder and fits the side wall of the forming cylinder. The push plate drives one end of the automobile shaft accessories through the driving sleeve to penetrate the impurity cylinder and enter the inside of the forming cylinder. One end of the automobile shaft accessories enters between the inner walls of the sponge grinding sheet inside the first group of annular airbags. The distance from the automobile shaft accessories to the inside of the annular airbag is one quarter of the overall width of the sponge grinding sheet. Then the operator inflates the annular airbag with air through the vacuum pump. After the annular airbag is inflated, the sponge grinding sheet is driven close to the surface of the automobile shaft accessories. The sponge The grinding sheet is made of soft and elastic materials, such as polyurethane, so that it can better adapt to and fit the surface of automobile shaft accessories during the grinding process. Therefore, the sponge grinding sheet has a certain elasticity and can be stretched to a certain extent. The sponge grinding sheet stops moving after it fits the surface of automobile shaft accessories. Under the action of the vacuum pump continuously inflating the annular airbag, the annular airbag drives the sponge grinding sheet to fit closely with the surface of automobile shaft accessories. The sensing threshold of the gas pressure sensor is pre-set, and the gas pressure value inside the annular airbag is monitored in real time by the gas pressure sensor. When the annular airbag is When the gas pressure value inside the bag reaches the threshold value set by the gas pressure sensor, the vacuum pump stops inflating the annular air bag, and then the driving motor drives the automobile shaft accessories to rotate through the driving sleeve and the clamping bolt, and the operator pushes the push plate, so that the automobile shaft accessories enter the inner wall of the sponge grinding sheet in a rotating state. Due to the strong fit between the sponge grinding sheet and the automobile shaft accessories, the iron filings ground by the sponge grinding sheet on the surface of the automobile shaft accessories flow into the impurity barrel, and the adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet magnetically adsorbs the iron filings ground inside the impurity barrel through the impurity port;

[0011] After being ground by the first group of sponge grinding discs, the diameter of the automobile shaft accessories is relatively shortened. When the automobile shaft accessories enter the second group of sponge grinding discs, the vacuum pump inflates the annular airbag of the second group. When the gas pressure value inside the annular airbag reaches the threshold of the gas pressure sensor, the vacuum pump stops inflating the annular airbag to ensure that the automobile shaft accessories are ground under the same force. When the automobile shaft accessories enter the third and fourth groups of sponge grinding discs, the same operation is performed. The vacuum pump inflates the annular airbag to reach the sensing threshold of the gas pressure sensor, and then the automobile shaft accessories are ground. The consistent grinding force helps to improve the texture of the workpiece surface and form a more complete and uniform surface ceramic film, thereby improving the hardness, mechanical strength, wear resistance and other physical properties of the workpiece.

[0012] Since there is a certain squeezing force between the sponge grinding sheet and the surface of the automobile shaft accessories, the iron chips generated by the second group of grinding automobile shaft accessories are retained between the first group of annular airbags and the second group of annular airbags. The external cold air pipe is connected with the angle adjustment mechanism of the inclination self-adjusting mechanism. The cold air enters the inside of the forming cylinder through the angle adjustment mechanism of the inclination self-adjusting mechanism to cool the grinding operation of the automobile shaft accessories. At the same time, the fluidity of the cold air drives the iron chips to flow into the impurity cylinder through the guide pipe for placement. The diameter of the workpiece opening is larger than the diameter of the workpiece, which facilitates the cold air to flow out of the impurity cylinder, thereby completing the removal of the iron chips retained between the first group and the second group, the second group and the third group, and the third group and the fourth group, thereby avoiding the appearance of tiny protrusions or pits on the workpiece surface due to the failure to remove the iron chips in time, thereby affecting the sealing and friction resistance of the automobile shaft accessories.

[0013] When one end of the automobile shaft accessories is ground, the direction of the automobile shaft accessories is turned, and the push plate is pulled. The push plate drives the automobile shaft accessories to extend out from the impurity cylinder and the forming cylinder through the elastic reset force of the guide spring, and the clamping bolt is rotated. The clamping bolt rotates along the driving sleeve to drive the anti-skid pad away from the surface of the automobile shaft accessories. The push plate is pulled again, and the push plate drives the limit plate to fit the side wall of the fixed cylinder to take the automobile shaft accessories out of the driving sleeve, and then the ground end of the automobile shaft accessories is placed into the driving sleeve, and the clamping bolt is rotated to clamp the automobile shaft accessories through the anti-skid pad, and then the above operation is repeated to grind the other end of the automobile shaft accessories.

[0014] Specifically, a controller is provided on the upper wall of the molding base.

[0015] Wherein, the controller is electrically connected to the adsorption electromagnet, the driving motor, the gas pressure sensor and the air pump respectively.

[0016] The beneficial effects achieved by adopting the above structure are as follows:

[0017] Compared with the prior art, this solution adopts an inclined structure to perform forming processing on automobile shaft accessories. With the coordinated use of the inclination self-adjusting mechanism and the heavy-drop pushing mechanism, the probability of iron filings remaining between the sponge grinding sheet and the automobile shaft accessories after grinding can be reduced, thereby ensuring the processing accuracy and surface finish of automobile shaft accessories. Under the action of the gas pressure sensor and the vacuum pump, the surface grinding force of automobile shaft accessories can be kept consistent, ensuring that the processing force applied to automobile shaft accessories during the grinding process is the same, avoiding the problem of unstable processing quality of automobile shaft accessories due to inconsistent processing force, thereby improving the overall quality of automobile shaft accessories after forming to a certain extent. The sponge grinding sheet has a certain elasticity and can be stretched to a certain extent. The sponge grinding sheet stops moving after being fitted with the surface of the automobile shaft accessories, and the vacuum pump continues to move in an annular direction. Under the action of inflation inside the airbag, the annular airbag drives the sponge grinding sheet to fit tightly with the surface of automobile shaft accessories. The sensing threshold of the gas pressure sensor is set in advance, and the gas pressure value inside the annular airbag is monitored in real time by the gas pressure sensor. When the gas pressure value inside the annular airbag reaches the threshold set by the gas pressure sensor, the vacuum pump stops inflating the annular airbag, and then the driving motor drives the automobile shaft accessories to rotate through the driving sleeve and the clamping bolt, and the operator pushes the push-in plate to make the automobile shaft accessories enter the inner wall of the sponge grinding sheet in a rotating state. Due to the large fit between the sponge grinding sheet and the automobile shaft accessories, the iron filings ground by the sponge grinding sheet on the surface of the automobile shaft accessories flow into the impurity barrel, and the adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet magnetically adsorbs the iron filings ground inside the impurity barrel through the impurity port.

[0039] The controller 33 is electrically connected to the adsorption electromagnet 11 , the driving motor 20 , the gas pressure sensor 30 and the air pump 31 , respectively.

[0040] When in use, the locking bolt 6 is manually rotated, and the locking bolt 6 is unscrewed from the inside of the rotating block 5. At this time, the rotating block 5 is in an active state. The operator drives the rotating block 5 to rotate around the adjusting column 2 through the fixed cylinder 8 to adjust the inclination angle of the impurity cylinder 9 and the forming cylinder 12, so that the iron filings generated by the forming cylinder 12 during the forming process of the automobile shaft accessories can slide off, and the iron filings can be avoided from remaining on the surface of the automobile accessories, resulting in a decrease in the processing accuracy and poor surface quality of the automobile accessories, thereby ensuring the quality and accuracy of the automobile accessories during the forming process;

[0041] Specifically, in the initial state, the guide spring 17 is extended, and a certain distance is maintained between the limit plate 18 and the side wall of the fixed cylinder 8. Then, the operator manually pulls the push plate 16, and the push plate 16 is deformed by the guide spring 17 to drive the guide rod 15 to slide along the side wall of the fixed cylinder 8. The guide rod 15 drives the limit plate 18 to fit with the side wall of the fixed cylinder 8, and one end of the automobile shaft accessory is placed into the driving sleeve 21. The clamping bolt 22 is manually rotated, and the clamping bolt 22 rotates along the driving sleeve 21 to drive the anti-skid pad 23 to fit with the automobile shaft accessory. The automobile shaft accessory is fixed in the driving sleeve 21, and then the push plate 16 is released. The guide spring 17 elastically resets and drives the other end of the automobile shaft accessory to enter the workpiece opening 24.

[0042] The operator pushes the push plate 16, and the push plate 16 drives the guide rod 15 to slide along the two ends of the fixed cylinder 8 through the compression deformation of the guide spring 17. The impurity cylinder 9 rotates along the fixed cylinder 8 and fits the side wall of the forming cylinder 12. The push plate 16 drives one end of the automobile shaft accessories to penetrate the impurity cylinder 9 and enter the inside of the forming cylinder 12 through the driving sleeve 21. One end of the automobile shaft accessories enters between the inner walls of the sponge grinding sheet 27 inside the first group of annular airbags 26. The distance from the automobile shaft accessories to the inside of the annular airbag 26 is one quarter of the overall width of the sponge grinding sheet 27. Then the operator The personnel controls the vacuum pump 31 to start through the controller 33, and the vacuum pump 31 inflates the annular airbag 26. After the annular airbag 26 is inflated, the sponge grinding sheet 27 is driven to approach the surface of the automobile shaft accessories. The sponge grinding sheet 27 is made of a soft and elastic material, such as polyurethane, so that it can better adapt to and fit the surface of the automobile shaft accessories during the grinding process. Therefore, the sponge grinding sheet 27 has a certain elasticity and can be stretched to a certain extent. After the sponge grinding sheet 27 is in contact with the surface of the automobile shaft accessories, it stops moving. While the vacuum pump 31 is maintained Under the action of continuously inflating the annular airbag 26, the annular airbag 26 drives the sponge grinding sheet 27 to closely fit the surface of the automobile shaft accessories. The sensing threshold of the gas pressure sensor 30 is pre-set, and the controller 33 controls the gas pressure sensor 30 to start, and the gas pressure value inside the annular airbag 26 is monitored in real time through the gas pressure sensor 30. When the gas pressure value inside the annular airbag 26 reaches the threshold set by the gas pressure sensor 30, the controller 33 controls the air pump 31 to stop inflating the annular airbag 26, and then drives the motor 20 to drive The sleeve 21 and the clamping bolt 22 drive the automobile shaft accessories to rotate, and the operator pushes the push plate 16, so that the automobile shaft accessories enter the inner wall of the sponge grinding sheet 27 in the rotating state. Since the sponge grinding sheet 27 and the automobile shaft accessories have a strong fit, the iron filings ground by the sponge grinding sheet 27 on the surface of the automobile shaft accessories flow into the impurity barrel 9. The controller 33 controls the adsorption electromagnet 11 to start, and the adsorption electromagnet 11 is energized to generate magnetism. The adsorption electromagnet 11 magnetically adsorbs the iron filings ground inside the impurity barrel 9 through the impurity port 10.

[0043] After being ground by the first group of sponge grinding sheets 27, the diameter of the automobile shaft accessories is relatively shortened. When the automobile shaft accessories enter the second group of sponge grinding sheets 27, the controller 33 controls the vacuum pump 31 to inflate the annular airbag 26 of the second group. When the gas pressure value inside the annular airbag 26 reaches the threshold of the gas pressure sensor 30, the vacuum pump 31 stops inflating the annular airbag 26 to ensure that the automobile shaft accessories are ground under the same force. When the automobile shaft accessories enter the third and fourth groups of sponge grinding sheets 27, the same operation is performed. The vacuum pump 31 inflates the annular airbag 26 to reach the sensing threshold of the gas pressure sensor 30, and then the automobile shaft accessories are ground. The consistent grinding force helps to improve the texture of the workpiece surface and form a more complete and uniform surface ceramic film, thereby improving the hardness, mechanical strength, wear resistance and other physical properties of the workpiece.

[0044] Since there is a certain squeezing force between the sponge grinding sheet 27 and the surface of the automobile shaft accessories, the iron chips generated by the second group of grinding automobile shaft accessories are retained between the first group of annular airbags 26 and the second group of annular airbags 26, and the external cold air pipe is connected with the inclination self-adjusting mechanism 3 and the angle adjustment mechanism 4. The cold air enters the inside of the forming cylinder 12 through the inclination self-adjusting mechanism 3 and the angle adjustment mechanism 4 to cool the grinding operation of the automobile shaft accessories. At the same time, the fluidity of the cold air drives the iron chips to flow into the impurity cylinder 9 through the guide pipe 28 for placement. The diameter of the workpiece opening 24 is larger than the diameter of the workpiece, which facilitates the cold air to flow out of the impurity cylinder 9, thereby completing the removal of the iron chips retained between the first group and the second group, the second group and the third group, and the third group and the fourth group, avoiding the appearance of tiny protrusions or pits on the workpiece surface due to the failure to remove the iron chips in time, thereby affecting the sealing and friction resistance of the automobile shaft accessories after forming.

[0045] When one end of the automobile shaft accessories is ground, the direction of the automobile shaft accessories is reversed, and the operator pulls the push plate 16. The push plate 16 drives the automobile shaft accessories to extend out from the impurity cylinder 9 and the forming cylinder 12 through the elastic reset force of the guide spring 17, and rotates the clamping bolt 22. The clamping bolt 22 rotates along the driving sleeve 21 to drive the anti-skid pad 23 away from the surface of the automobile shaft accessories. The push plate 16 is pulled again, and the push plate 16 drives the limit plate 18 to fit with the side wall of the fixed cylinder 8, and the automobile shaft accessories are taken out from the driving sleeve 21. Then, the ground end of the automobile shaft accessories is placed into the driving sleeve 21, and the clamping bolt 22 is rotated to clamp the automobile shaft accessories through the anti-skid pad 23. Then, the above operation is repeated to grind the other end of the automobile shaft accessories.

[0047] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
