[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] Please refer to the following: Figure 1 and Figure 2 The present invention will now describe the equipment for processing magnetic steel holes on the inner and outer walls of a drum. The equipment includes an operating table 1, a driving component 2, an adjusting unit 3, and a drilling device 4. The driving end of the driving component 2 is connected to a driving shaft 21, which drives the drum to rotate on the operating table 1. The adjusting unit 3 is mounted on the operating table 1 and is used to adjust the position of the drum on the operating table 1 so that the axis of the drum coincides with the axis of the driving shaft 21. The drilling device 4 is equipped with a movable arm that moves along the axis of the driving shaft 21, and a working part for processing magnetic steel holes on the drum is mounted on the movable arm.

[0047] The magnetic steel hole processing equipment for the inner and outer walls of the roller provided in this embodiment, compared with the prior art, features an operating table 1 with an adjustment unit 3 for placing the roller. A drive component 2 for rotating the roller is located on one side of the operating table 1. The drive component 2 uses a CNC machine tool to drive the drive shaft 21, thereby achieving precise control of the roller's rotation angle during rotation. A drilling device 4 is located on the opposite side of the drive component 2. The drilling device 4 achieves precise drilling on the roller's sidewall by driving a moving arm to move along the axial direction of the drive shaft 21. In this application, the drilling device 4 uses a CNC drilling machine, which can process multiple magnetic steel holes on the roller's sidewall along the axial direction of the drive shaft 21. In use, the roller is hoisted onto the adjustment unit 3, and the adjustment unit 3 is used to adjust the roller to maintain coaxiality with the drive shaft 21, thus fixing the drive shaft 21 to the roller. By setting the drilling program inside the drilling device 4, the drilling device 4 operates, drilling along the axis of the drive shaft 21. After one row of holes is processed, the drive component 2 controls the roller to rotate at a certain angle. The drilling device 4 then restarts to drill. This process of roller rotation and drilling is repeated to complete the processing of the magnetic holes on the entire side wall of the roller. This effectively improves the processing efficiency of the magnetic holes and reduces labor costs.

[0048] Specifically, in this embodiment, the equipment for processing magnetic steel holes on the inner and outer walls of the drum also includes a controller. After the drilling device 4 completes the processing of a row of magnetic steel holes, the drilling device 4 sends a signal to the controller. The controller controls the drive component 2 to work, and the drive component 2 drives the drum to rotate at a certain angle according to the program settings. After the rotation is completed, a feedback signal is sent to the controller, and the controller controls the drilling device 4 to work, thereby realizing continuous drilling operations.

[0049] Specifically, in this embodiment, a drilling mechanism is also provided between the driving member 2 and the drilling device 4. The working part on the drilling mechanism is used to drill holes in the radial direction of the driving shaft 21. It can drill holes on the outer wall of the drum, so as to realize the simultaneous processing or separate processing of the inner hole and the outer hole of the drum.

[0050] In some embodiments, the adjustment unit 3 described above may employ, for example... Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The adjustment unit 3 includes two support rollers 31 and a drive mechanism 32. The axes of the support rollers 31 are parallel to the axis of the drive shaft 21, forming a support position for placing the roller. The drive mechanism 32 is positioned between the two support rollers 31 and drives them to move closer or further apart. The two support rollers 31 are rotatably mounted on the operating table 1. When the drive unit 2 drives the support rollers 31 to rotate, they rotate together with the roller without affecting its operation. The drive mechanism 32 can drive the support rollers 31 to move horizontally in a direction perpendicular to the axis of the drive shaft 21, thereby changing the position of the roller. This design simplifies operation and reduces complex operations such as hoisting the roller during position adjustment.

[0051] Optionally, in this embodiment, each of the two support rollers 31 is provided with a separate drive mechanism 32, which can independently adjust the position of the support roller 31 on the operating table 1. This facilitates adjustment of the roller's position in the height direction and horizontal direction along the direction perpendicular to the drive shaft 21.

[0052] In some embodiments, the support roller 31 may be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 Both support rollers 31 are located on the same horizontal plane, and the axes of the two support rollers 31 are equidistant from the axis of the drive shaft 21. When the roller is placed between the two support rollers 31, the projection of the roller's axis and the axis of the drive shaft 21 in the vertical direction coincides. After the roller is placed between the two support rollers 31, the roller can be moved vertically by driving the two support rollers 31 to move synchronously relative to each other. This makes it easier to align the coaxiality of the roller and the drive shaft 21. In use, by placing the roller between the two support rollers 31, the outer wall of the roller abuts against the two support rollers 31, achieving horizontal positioning of the roller in the direction perpendicular to the axis of the drive shaft 21. The height of the roller can then be adjusted by adjusting the distance between the two support rollers 31. This is convenient to operate and shortens the time required to adjust the position of the roller on the operating table 1.

[0053] In some embodiments, the drive mechanism 32 described above may employ, for example... Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The drive mechanism 32 includes a fixed frame 321, a drive rod 323, and threaded sleeves 324. The fixed frame 321 is mounted on the operating table 1, and two support frames 322 are slidably mounted on the fixed frame 321. Support rollers 31 are rotatably mounted on the support frames 322. The drive rod 323 is rotatably mounted on the fixed frame 321. Two threaded sleeves 324 are mounted on the two support frames 322 respectively, and the threaded holes on the two threaded sleeves 324 have opposite directions of rotation and are both threadedly connected to the drive rod 323. The drive rod 323 has two threaded sections with opposite directions of rotation and the same thread pitch. In use, rotating the drive rod 323 synchronously moves the two support frames 322 together, thereby adjusting the distance between the two support rollers 31.

[0054] Optionally, in this embodiment, a turntable is fixedly installed at the end of the drive rod 323, and the drive rod 323 can be rotated by rotating the turntable.

[0055] Optionally, in this embodiment, a motor is fixedly installed on the fixed frame 321, and the drive shaft 21 of the motor is connected to the drive rod 323. The distance between the two support rollers 31 can be adjusted by controlling the working state of the motor.

[0056] Specifically, in this embodiment, the processing of magnetic steel holes on the inner and outer walls of the roller can be switched by adjusting the height of the roller.

[0057] In some embodiments, the drive shaft 21 may be as follows: Figure 2 , Figure 9 The structure shown. See also... Figure 2 , Figure 9 The drive shaft 21 is also equipped with a connecting arm for connecting to the roller. The connecting arm includes a connecting plate 22, a mounting plate 222, and a tightening member 223. The connecting plate 22 is fixedly mounted on the drive shaft 21, and multiple connecting plates 221 are provided on the connecting plate 221, with the length direction of the multiple connecting plates 221 arranged radially along the drive shaft 21. The mounting plate 222 is fixedly connected to the connecting plates 221, and the mounting plate 222 is provided with mounting holes for fixed connection to the end of the roller. The tightening member 223 is provided through the mounting plate 222 and is used to fix the mounting plate 222 to the end of the roller. Threaded holes are machined at the end of the roller, and the tightening member 223 is a bolt. The mounting plate 222 can be fixedly connected to the end of the roller through the tightening member 223, which can avoid damage to the inner or outer wall of the roller when the drive shaft 21 is connected to the roller, and can improve the rotational accuracy of the roller.

[0058] Optionally, in this embodiment, the threaded hole connecting the roller end to the tightening member 223 is the same threaded hole that is later connected to the roller end cover. This avoids the need to machine the threaded hole separately at the roller end.

[0059] Specifically, a fixing sleeve is provided between the connecting plate 22 and the drive shaft 21. The fixing sleeve includes a first arc-shaped plate, a second arc-shaped plate, and fasteners. The axis of the first arc-shaped plate is parallel to the axis of the drive shaft 21, and one end of the first arc-shaped plate is fixedly mounted on the connecting plate 22. The second arc-shaped plate is detachably connected to the first arc-shaped plate, and the second arc-shaped plate and the first arc-shaped plate form an installation space for accommodating the drive shaft 21. Fasteners are provided between the first arc-shaped plate and the second arc-shaped plate to press the drive shaft 21 between the first arc-shaped plate and the second arc-shaped plate. The inner arcs of the first arc-shaped plate and the second arc-shaped plate are arc-shaped structures adapted to the outer side of the drive shaft 21. Wing plates are fixedly connected to both sides of the first arc-shaped plate and the second arc-shaped plate. The fasteners fix the drive shaft 21 between the first arc-shaped plate and the second arc-shaped plate by threading through the wing plates on the first arc-shaped plate and connecting with the wing plates on the second arc-shaped plate. This facilitates the connection and fixation between the connecting plate 22 and the drive shaft 21.

[0060] Specifically, in this embodiment, a clearance hole is provided on the connecting plate 22 to allow the drive shaft 21 to pass. This allows for convenient adjustment of the position of the connecting plate 22 along the length of the drive shaft 21.

[0061] Specifically, in this embodiment, an anti-rotation key is provided between the fixed sleeve and the drive shaft 21 to prevent the fixed sleeve from rotating on the drive shaft 21. Keyways for installing the anti-rotation key are provided on both the fixed sleeve and the drive shaft 21. The length direction of the keyway is along the axial direction of the drive shaft 21. By providing the anti-rotation key, rotation of the fixed sleeve on the drive shaft 21 can be prevented, avoiding relative displacement between the fixed sleeve and the drive shaft 21 that could affect the rotation angle of the roller.

[0062] Optionally, in this embodiment, a keyway for placing an anti-rotation component is provided on the drive shaft 21. The length of the keyway is set along the length direction of the drive shaft 21, and the keyway extends through both ends of the drive shaft 21.

[0063] Optionally, in this embodiment, the connecting plate 221 is provided with an elongated through hole for fixed connection with the connecting disk 22, and the length direction of the elongated through hole is along the length direction of the connecting plate 221. The elongated through hole on the connecting plate 221 allows adjustment of the position of the connecting plate 221 on the connecting disk 22 along the radial direction of the drive shaft 21. The position of the mounting plate 222 can be adjusted according to rollers of different diameters, thus making this application applicable to the processing of permanent magnet mounting holes on rollers of different diameters. An arc-shaped through hole corresponding to the elongated through hole is provided on the connecting disk 22. When the connecting disk 22 is installed on the drive shaft 21, the center of the arc-shaped through hole is located on the axis of the drive shaft 21. The arc-shaped through hole facilitates adjustment of the position of the mounting plate 222, allowing the mounting holes on the mounting plate 222 to align with the threaded holes at the ends of the rollers.

[0064] In some embodiments, the drive shaft 21 may be as follows: Figure 2 , Figure 7 The structure shown. See also... Figure 2 , Figure 7 The drive unit 2 is also equipped with a chuck 23, and a fixed disk is fixedly connected to the drive shaft 21. The fixed disk is coaxial with the drive shaft 21. The chuck 23 is equipped with jaws 231 for fixing the fixed disk onto the chuck 23. The chuck 23 is a conventional three-jaw chuck 23. The fixed disk can be clamped onto the chuck 23 by using a clamping mechanism. The fixed disk has a cylindrical structure and is coaxial with the drive shaft 21.

[0065] In some embodiments, the aforementioned fixed disk may be adopted as follows: Figure 2 , Figure 7 The structure shown. See also... Figure 2 , Figure 7 A fixing assembly for mounting the jaw 231 is fixedly installed on the fixed plate. The fixing assembly includes a fixing block 232 and a clamping member 233. There are two fixing blocks 232, both of which are fixed on the fixed plate, and the two fixing blocks 232 form a placement groove for accommodating the jaw 231. The clamping member 233 is threadedly connected to the fixing blocks 232, and one end of the clamping member 233 is located inside the placement groove to fix the jaw 231 in the placement groove. The fixing blocks 232 are fixedly installed on the fixed plate by bolts or welding. When the fixed plate is installed on the chuck 23, the fixing blocks 232 are located on the side of the fixed plate away from the chuck 23, and the jaw 231 protrudes from the side of the chuck 23 closer to the fixed plate. The clamping member 233 is a bolt. When the fixed plate is installed on the chuck 23, the jaw 231 is located in the placement groove. By rotating the clamping member 233, the end of the clamping member 233 can abut against the jaw 231. The two fixing blocks 232 are located on both sides of the jaw 231, thereby clamping the jaw 231 between the two fixing blocks 232. The operation is convenient and facilitates the installation and removal of the fixed plate and the chuck 23.

[0066] In some embodiments, the aforementioned connecting disk 22 may adopt the following... Figure 2 , Figure 4 , Figure 5 and Figure 6 The structure shown. See also... Figure 2 , Figure 4 , Figure 5 and Figure 6A buffer unit 24 for preventing roller warping is also provided between the connecting plate 22 and the drive shaft 21. The buffer unit 24 includes a center plate 241, a fixed plate 242, and a tightening assembly 25. The center plate 241 is located on one side of the connecting plate 22 and has a degree of freedom to slide along a first direction on the connecting plate 22. The fixed plate 242 and the connecting plate 22 are located on opposite sides of the center plate 241. The connecting plate 22 is fixedly connected to the drive shaft 21, and the center plate 241 has a degree of freedom to slide along a second direction on the fixed plate 242. The first direction and the second direction are perpendicular to each other and are both radially arranged along the drive shaft 21. The tightening assembly 25 is provided between the connecting plate 22, the fixed plate 242, and the center plate 241 to tighten the fixed plate 242 and the connecting plate 22 towards the center plate 241. In use, the connecting plate 22 is fixedly installed on the drive shaft 21 of the drive component 2, and the fixed plate 242 is fixedly connected to the roller. The connecting plate 22 is connected to the fixed plate 242 and the center plate 241 via tightening components 25. There are multiple tightening components 25, and when the connecting plate 22 is installed on the drive shaft 21, the multiple tightening components 25 are evenly arranged around the outside of the drive shaft 21. To ensure uniform force distribution between the connecting plate 22, the center plate 241, and the fixing plate 242, this application, during use, involves installing the connecting plate 22 onto the drive shaft 21 of the drive component 2 and connecting the fixing plate 242 to the roller. When the drive shaft 21 of the drive component 2 drives the roller to rotate, if the axis of the drive shaft 21 and the roller are not coaxial, the center plate 241 will slide relative to the connecting plate 22 in a first direction during the rotation of the drive shaft 21, and the fixing plate 242 will slide relative to the center plate 241 in a second direction. This compensates for the error in the relative position of the axes between the drive shaft 21 and the roller, ensuring that the axis of the drive shaft 21 and the axis of the roller remain parallel, preventing the roller from warping and affecting the service life of the drive shaft 21 and the machining accuracy of the magnetic holes on the roller.

[0067] In some embodiments, the aforementioned center plate 241 may adopt the following... Figure 2 , Figure 4 and Figure 5 The structure shown. See also... Figure 2 , Figure 4 and Figure 5The center plate 241 and the connecting plate 22 are respectively provided with a first sliding key 2411 and a first sliding groove arranged along a first direction. The first sliding key 2411 and the first sliding groove are slidably engaged. A second sliding key 2412 and a second sliding groove arranged along a second direction are also provided between the center plate 241 and the fixing plate 242. The second sliding key 2412 and the second sliding groove are slidably engaged. The sliding engagement between the connecting plate 22 and the center plate 241 is achieved through the sliding engagement of the first sliding groove and the first sliding key 2411. The connection structure between the fixing plate 242 and the center plate 241 is the same as that between the connecting plate 22 and the center plate 241. Both the connecting plate 22 and the fixing plate 242 are provided with clearance holes to avoid the drive shaft 21, thereby facilitating the connection between the connecting plate 22 and the drive shaft 21. The tightening component 25 can simultaneously prevent the first slide key 2411 from sliding out of the first slide groove and the second slide key 2412 from sliding out of the second slide groove.

[0068] Optionally, in this embodiment, the first slide key 2411 has a degree of freedom to slide towards or away from the bottom of the first slide groove inside the first slide groove, and the second slide key 2412 has a degree of freedom to slide towards or away from the bottom of the second slide groove inside the second slide groove. The second slide key 2412 has the same structure as the first slide key 2411. The first slide groove and the second slide groove have the same structure. The cross-section of the first slide key 2411 and the first slide groove along the direction perpendicular to the length of the first slide key 2411 is a directional structure, which allows the first slide key 2411 to slide away from the bottom of the first slide groove. Thus, when the axis of the drive shaft 21 is not parallel to the axis of the roller, the angle between the drive shaft 21 and the roller can be balanced by the tilt angle of the first slide key 2411 inside the first slide groove. This avoids the drive shaft 21 from bending due to the angle between the roller and the drive shaft 21.

[0069] Specifically, in this embodiment, the tightening component 25 is used to limit the displacement of the connecting disc 22 and the fixing plate 242 relative to the center plate 241 along the axis of the drive shaft 21. This can prevent the first sliding key 2411 from sliding out of the first sliding groove, or the second sliding key 2412 from sliding out of the second sliding groove, thereby improving stability during use.

[0070] Optionally, in this embodiment, the first slide key 2411 and the second slide key 2412 are respectively fixedly installed on both sides of the center plate 241. This allows the connecting discs 22 and the fixing plates 242 on both sides to have the same structure with the first slide groove and the second slide groove, respectively. This facilitates the processing of the connecting discs 22 and the fixing plates 242.

[0071] Optionally, the connection method between the fixing plate 242 and the drive shaft 21 is the same as the connection method between the connecting plate 22 and the drive shaft 21.

[0072] In some embodiments, the tightening component 25 may employ, for example... Figure 2 , Figure 4 and Figure 6 The structure shown. See also... Figure 2 , Figure 4 and Figure 6 The tightening assembly 25 includes a connecting rod 251 and an elastic element 253. The connecting rod 251 passes through the connecting plate 22 and the center plate 241, and is fixedly connected to the fixing plate 242. A limiting platform 252 is provided at the end of the connecting rod 251 away from the connecting plate 22. The elastic element 253 is disposed between the connecting rod 251 and the connecting plate 22, with one end of the elastic element 253 abutting against the limiting platform 252 and the other end abutting against the connecting plate 22. The connecting rod 251 and the limiting platform 252 are an integral structure, and the connecting rod 251 and the limiting platform 252 are coaxial cylindrical structures. The outer diameter of the limiting platform 252 is larger than the outer diameter of the connecting rod 251. The elastic element 253 is a spring, which is sleeved on the connecting rod 251, with one end of the elastic element 253 abutting against the limiting platform 252 and the other end abutting against the connecting plate 22. The connecting rod 251 is threadedly connected to the fixing plate 242, thereby achieving a fixed connection between the connecting rod 251 and the fixing plate 242. Under the push of the elastic element 253, the connecting plate 22 moves towards the center plate 241, and the fixing plate 242 is pulled towards the center plate 241 under the pull of the connecting rod 251, so that both the connecting plate 22 and the fixing plate 242 can move towards the center plate 241.

[0073] Specifically, in this embodiment, the connecting plate 22 and the center plate 241 are provided with through holes for avoiding the connecting rod 251, and there is a sway gap between the inner wall of the through hole and the connecting rod 251. The inner diameter of the through hole is larger than the outer diameter of the connecting rod 251, so that the connecting rod 251 can change angle relative to the center plate 241 and the connecting plate 22. Therefore, when there is an angle difference between the axis of the drive shaft 21 and the roller, interference between the connecting rod 251 and the connecting plate 22 or the center plate 241 can be prevented, thus improving the stability during use.

[0074] Specifically, in this embodiment, a gasket is also provided between the elastic element 253 and the connecting plate 22, with one end of the elastic element 253 abutting against the gasket. The inner hole of the gasket is slidably engaged with the connecting rod 251, and the outer diameter of the gasket is larger than the inner diameter of the through hole on the connecting plate 22. This allows the elastic element 253 to abut against the gasket without being damaged, and prevents the elastic element 253 from sliding into the through hole, thus improving stability during use.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
