Description

Technical Field

[0001] This utility model relates to the field of magnetic polishing machine technology, specifically an auxiliary device for a magnetic polishing machine. Background Technology

[0002] During the processing of bolts and nuts, burrs and rough marks are left on the surface of the bolts and nuts after cutting. After magnetic polishing, the surface is smooth, so that the bolts and nuts can fit better. Therefore, a magnetic polishing machine is needed.

[0003] A Chinese patent with authorization announcement number CN117103100B discloses a magnetic polishing machine for parts processing, including a mounting bracket. The main body of the magnetic polishing machine is fixedly mounted on the upper end of one side of the mounting bracket, and a transfer mechanism is provided on the upper end of the other side of the mounting bracket. A separation mechanism and a circulation mechanism are fixedly mounted on the mounting bracket. Through the coordinated use of the main body of the magnetic polishing machine, the transfer mechanism and the separation mechanism, the parts loading operation, cleaning and drying operation and material unloading operation can be carried out simultaneously, thereby effectively improving processing efficiency. Through the coordinated use of the separation mechanism and the circulation mechanism, the polished parts and polishing liquid can be easily separated, and the separated polishing liquid can be easily introduced into another corresponding placement cylinder for recycling, thereby saving resources.

[0004] However, the aforementioned magnetic polishing machine still has some problems. In practical applications, the magnetic disk is installed in a certain position and rotates. The movement pattern of the steel balls under the action of the magnetic field is relatively simple and cannot be effectively guided to various parts of the workpiece. For some hard-to-reach corners and depressions on the surface of the workpiece, sufficient polishing cannot be performed, resulting in uneven polishing of the workpiece. Therefore, an auxiliary device for magnetic polishing machine is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes an auxiliary device for a magnetic polishing machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A magnetic polishing machine auxiliary device of this utility model includes a machine body. An installation groove is formed inside the machine body. A sliding groove is formed inside the bottom side of the installation groove. A sliding block is slidably installed inside the sliding groove. A mounting seat is installed on the top side of the sliding block. A drive motor is installed inside the mounting seat. An installation ring is installed at the output end of the drive motor. A magnetic disk is assembled inside the installation ring. A rack is installed on one side of the top of the sliding block. A support column is installed on the bottom inner wall of the installation groove. A servo motor is installed at the top of the support column. A circular gear is installed at the output end of the servo motor, and the circular gear meshes with the rack, realizing the reciprocating motion of the magnetic disk, thereby assisting the steel balls in better polishing the workpiece.

[0007] Preferably, two support plates are symmetrically installed at the top edge of the machine body. A rotating shaft is rotatably installed inside the support plate, and a polishing cavity is installed at one end of the rotating shaft, so that the polished workpiece can be discharged through the inclined polishing cavity.

[0008] Preferably, a driven gear is installed on the outer side of the other end of one of the rotating shafts, a support rod is installed on the top side of the machine body, a stepper motor is installed at the top of the support rod, a driving gear is installed on the working end of the stepper motor, and the driving gear and the driven gear mesh with each other, so that the polishing chamber can rotate at a predetermined angle and speed, thereby realizing the material discharge operation.

[0009] Preferably, a mounting plate is fixedly connected to the bottom edge of one side of the polishing chamber, away from the rotation axis. A trigger rod is fixedly connected to the bottom side of the mounting plate. A trigger switch is installed on the top side of the machine body directly below the trigger rod. The trigger switch is used to shut down the stepper motor, so as to stop the rotation of the stepper motor in time when the polishing chamber returns to its original position after material discharge, and avoid the polishing chamber and the magnetic disk from being out of parallel, which would affect the polishing operation.

[0010] Preferably, a fixing plate is fixedly connected to both sides of the top of the polishing cavity, a cylinder is installed on the bottom side of the fixing plate, an actuating rod is installed on the working end of the cylinder, and a side lug is installed on the top side of the actuating rod. A cover plate is fixedly connected between the side lugs. The cover plate is matched with the size of the polishing cavity to avoid splashing of polishing liquid or steel balls during the polishing process, thus ensuring the cleanliness and safety of the polishing environment.

[0011] Preferably, a control panel is installed on one side of the machine body. The control panel is electrically connected to the trigger switch and the stepper motor, and is used for signal transmission to the trigger switch and operation control of the stepper motor, thereby improving the automation level of the device.

[0012] The advantages of this utility model are:

[0013] 1. This utility model starts a servo motor and a drive motor. The servo motor drives the circular gear at its output end to rotate, so that the rack drives the sliding block to move linearly in the left and right direction along the slide groove. The mounting base and the magnetic disk will move left and right with the sliding block, and the output end of the drive motor will drive the magnetic disk base to move in a circular motion. During the movement of the magnetic disk, the steel balls located in the polishing cavity continuously change their motion state and position under the action of magnetic force, thereby polishing the workpiece placed in the polishing cavity in a comprehensive and uniform manner.

[0014] 2. In this invention, the output end of the stepper motor rotates in reverse. When the trigger rod touches the trigger switch as the polishing cavity rotates, the trigger switch transmits a signal to the control panel. After receiving the signal, the control panel controls the stepper motor to stop working, thereby realizing the timely stopping of the stepper motor's rotation when the polishing cavity returns to its original position after material discharge, avoiding the polishing cavity from being out of parallel with the magnetic disk, which would affect the next polishing operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3 As shown, an auxiliary device for a magnetic polishing machine includes a body 1. The body 1 has an internal mounting groove 2. A sliding groove 3 is formed inside the bottom side of the mounting groove 2. A sliding block 4 is slidably mounted inside the sliding groove 3. A mounting seat 5 is mounted on the top side of the sliding block 4. A drive motor 6 is mounted inside the mounting seat 5. A mounting ring 7 is mounted at the output end of the drive motor 6. A magnetic disk 8 is assembled inside the mounting ring 7. A rack 9 is mounted on one side of the top of the sliding block 4. A support column 10 is mounted on the inner wall of the bottom side of the mounting groove 2. A servo motor 11 is mounted at the top of the support column 10. A circular gear 12 is mounted at the output end of the servo motor 11, and the circular gear 12 meshes with the rack 9.

[0024] The polishing cavity 15 has fixed plates 23 on both sides of its top end. A cylinder 24 is mounted on the bottom side of the fixed plate 23. An actuating rod 25 is mounted on the working end of the cylinder 24. Side ears 26 are mounted on the top side of each actuating rod 25. A cover plate 27 is fixedly connected between the side ears 26. The cover plate 27 is appropriately sized to match the polishing cavity 15. During operation, in practical applications, the magnetic disk 8 rotates in a certain position. The movement pattern of the steel balls under the magnetic field is relatively simple and cannot be effectively guided to various parts of the workpiece. This affects the surface finish of the workpiece. Some hard-to-reach corners and recesses cannot be fully polished, resulting in uneven polishing of the workpiece. First, the workpiece to be polished, steel balls, and cleaning agent are placed into the polishing chamber 15. Then, the cylinder 24 is activated. The working end of the cylinder 24 drives the side ear 26 and the cover plate 27 to move downward through the action rod 25. The cover plate 27 is matched with the size of the polishing chamber 15. When the cover plate 27 covers the top of the polishing chamber 15, a relatively sealed polishing space is formed, which effectively avoids the splashing of polishing liquid or steel balls during the polishing process and ensures the cleanliness and safety of the polishing environment.

[0025] Subsequently, the servo motor 11 and the drive motor 6 are started. The servo motor 11 drives the circular gear 12 at its output end to rotate. Since the circular gear 12 meshes with the rack 9, the rotation of the circular gear 12 will cause the rack 9 to drive the sliding block 4 to move linearly in the left and right direction along the slide groove 3. The mounting base 5 and the magnetic disk 8 will move left and right with the sliding block 4, and the output end of the drive motor 6 will drive the magnetic disk 8 to move in a circular motion. During the movement of the magnetic disk 8, the steel balls located in the polishing cavity 15 continuously change their motion state and position under the action of magnetic force, thereby polishing the workpiece placed in the polishing cavity 15 in a comprehensive and uniform manner.

[0026] Please see Figure 1 , 2 As shown in Figures 4 and 5, two support plates 13 are symmetrically installed on the top edge of the machine body 1. A rotating shaft 14 is rotatably installed inside the support plate 13. A polishing cavity 15 is installed at one end of the rotating shaft 14. A driven gear 16 is installed on the outer side of the other end of one of the rotating shafts 14. A support rod 17 is installed on the top side of the machine body 1. A stepper motor 18 is installed at the top of the support rod 17. A driving gear 19 is installed at the working end of the stepper motor 18, and the driving gear 19 meshes with the driven gear 16.

[0027] A mounting plate 20 is fixed to the bottom edge of one side of the polishing chamber 15, away from the rotating shaft 14. A trigger rod 21 is fixed to the bottom side of the mounting plate 20. A trigger switch 22 is installed on the top side of the machine body 1, directly below the trigger rod 21. The trigger switch 22 is used to turn off the stepper motor 18. A control panel 28 is installed on one side of the machine body 1. During operation, after the bolts and nuts are processed, burrs and rough marks will be left on their surface. After magnetic polishing, the surface is smooth, allowing the bolts and nuts to fit better. Therefore, a magnetic polishing machine is needed. When the polishing operation is completed and the material needs to be discharged, the stepper motor 18 starts to work. The stepper motor 18 drives the drive gear 19 to rotate. Since the drive gear 19 and the driven gear 16 mesh with each other, the rotating shaft 14 rotates, which causes the polishing chamber 15 to tilt around the rotating shaft 14. Through this tilting rotation, the workpiece in the polishing chamber 15 moves to one side under the action of gravity, thereby realizing the material discharge operation.

[0028] After the material is discharged, when the polishing chamber 15 needs to be returned to its original position, the output end of the stepper motor 18 rotates in the opposite direction. When the trigger rod 21 touches the trigger switch 22 as the polishing chamber 15 rotates, the trigger switch 22 will transmit a signal to the control panel 28. After receiving the signal, the control panel 28 controls the stepper motor 18 to stop working, thereby realizing the timely stop of the rotation of the stepper motor 18 when the polishing chamber 15 is returned to its original position after material discharge, and avoiding the polishing chamber 15 from being out of parallel with the magnetic disk 8, which would affect the next polishing operation.

[0029] Working principle: First, the workpiece to be polished, steel balls, and cleaning agent are placed into the polishing chamber 15. Then, the cylinder 24 is activated. The working end of the cylinder 24 drives the side ear 26 and the cover plate 27 to move downward through the rod 25. The cover plate 27 is matched with the size of the polishing chamber 15. When the cover plate 27 covers the top of the polishing chamber 15, a relatively sealed polishing space is formed, which effectively avoids the splashing of polishing liquid or steel balls during the polishing process and ensures the cleanliness and safety of the polishing environment.

[0030] Subsequently, the servo motor 11 and the drive motor 6 are started. The servo motor 11 drives the circular gear 12 at its output end to rotate. Since the circular gear 12 meshes with the rack 9, the rotation of the circular gear 12 will cause the rack 9 to drive the sliding block 4 to move linearly in the left and right direction along the slide groove 3. The mounting base 5 and the magnetic disk 8 will move left and right with the sliding block 4, and the output end of the drive motor 6 will drive the magnetic disk 8 to move in a circular motion. During the movement of the magnetic disk 8, the steel balls located in the polishing cavity 15 will continuously change their motion state and position under the action of magnetic force, thereby polishing the workpiece placed in the polishing cavity 15 in a comprehensive and uniform manner.

[0031] When the polishing operation is completed and the material needs to be unloaded, the stepper motor 18 starts to work. The stepper motor 18 drives the drive gear 19 to rotate. Since the drive gear 19 and the driven gear 16 mesh with each other, the rotating shaft 14 rotates, which causes the polishing cavity 15 to tilt around the rotating shaft 14. Through this tilting rotation, the workpiece in the polishing cavity 15 moves to one side under the action of gravity, thereby realizing the unloading operation.

[0032] After the material is discharged, when the polishing chamber 15 needs to be returned to its original position, the output end of the stepper motor 18 rotates in the opposite direction. When the trigger rod 21 touches the trigger switch 22 as the polishing chamber 15 rotates, the trigger switch 22 will transmit a signal to the control panel 28. After receiving the signal, the control panel 28 controls the stepper motor 18 to stop working, thereby realizing the timely stop of the rotation of the stepper motor 18 when the polishing chamber 15 is returned to its original position after material discharge, and avoiding the polishing chamber 15 from being out of parallel with the magnetic disk 8, which would affect the next polishing operation.
