Description

Technical Field

[0001] This invention relates to the field of roller grinding technology, and more specifically, to a grinding apparatus suitable for rollers and its working method. Background Technology

[0002] The rollers of a copier-printer are a critical component of the equipment. They help paper pass steadily through the printing system and play a vital role in print quality and stability. The manufacturing process of the rollers for a copier-printer involves multiple steps, including material selection, design, CNC machining, heat treatment, surface treatment, and multiple tests and quality inspections, to ensure that the quality and performance of the product meet the requirements.

[0003] Currently, the rollers of multifunction printers on the market are usually secured at the tail end using a triangular chuck, while the front end is fixed with a two-point clamping method. The rollers of the multifunction printer are processed by clamping at both ends. During the grinding process of the roller surface, the triangular chuck at the tail end can reduce vibration during processing and prevent the roller from falling off during processing. The triangular chuck can adjust the clamping opening according to the size of the roller, which is convenient for processing rollers of different sizes.

[0004] During the processing of the rollers in a multi-function printer / copier, vibrations occur. These vibrations lead to uneven force distribution on the roller contact surface, increased friction between the roller and the clamping components, and material loss and wear at the friction points, thus shortening the roller's lifespan. Furthermore, multi-function printer / copier rollers require high surface precision, and vibrations must be avoided as much as possible during processing to prevent surface roughness. The balance and uniformity of the rollers can also be compromised by unstable clamping during processing. Current two-point clamping systems do not provide sufficient clamping force for special rollers and cannot accommodate all multi-function printer / copier rollers. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a grinding equipment and its working method suitable for rollers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A grinding device for rollers includes a grinding unit, an adjustment unit mounted on one side of the grinding unit, a clamping unit mounted on one end of the grinding unit, and a support unit mounted above the grinding unit.

[0008] The grinding unit includes a roller and a grinding mechanism, and the support unit includes a support frame, a drive mechanism mounted on the support frame, a connecting frame mounted in the middle of the support frame, and a first gripper and a second gripper arranged on both sides of the connecting frame.

[0009] The adjustment unit includes a connecting seat, on which an electric slide rail is mounted. A slider is slidably mounted on the electric slide rail. A fixed block is mounted on the slider. A swing motor is mounted on one side of the fixed block. A swing plate is rotatably mounted on the swing motor. A rotating motor is mounted on the swing plate. A fixed component is rotatably mounted on the rotating motor.

[0010] The present invention is further configured such that: the grinding unit includes a grinding base, the grinding base is L-shaped, a housing is installed at one end of the grinding base away from the clamping unit, a triangular chuck is installed on the housing, a ventilation opening is provided on the triangular chuck, and a roller shaft is clamped in the middle of the triangular chuck.

[0011] The present invention is further configured such that: a grinding slide rail is installed on one side of the grinding base, a grinding slider is slidably installed on the grinding slide rail, the grinding slider is fixedly connected to the grinding mechanism, the grinding mechanism includes a mounting plate, one side of the mounting plate is connected to the grinding slider, a slide block is installed on the other side of the mounting plate, a rotating block is rotatably installed above the slide block, and a grinding swing arm is installed on the rotating block.

[0012] The present invention is further configured such that: the fixing component includes a lifting plate, the lifting plate is rotatably mounted on a rotating motor, a lifting seat is mounted on the lifting plate, the lifting seat is above the rotating motor, a lifting cylinder is mounted on the lifting seat, an adjusting plate is mounted on the output end of the lifting cylinder, and a pressure shaft mechanism is mounted on the adjusting plate.

[0013] The present invention is further configured such that: the pressure shaft mechanism includes a pressure shaft seat, the pressure shaft seat is connected to the adjusting plate, a pressure shaft block is installed on the pressure shaft seat, a bottom mounting block is installed below one side of the pressure shaft block, a pressure shaft cylinder is rotatably installed on the bottom mounting block, and a rotating shaft is rotatably arranged above one side of the pressure shaft block.

[0014] The present invention is further configured such that: a pressure block is installed on the rotating shaft, a top mounting block is installed below the pressure block near one end of the bottom mounting block, and the output end of the pressure shaft cylinder is hinged to the top mounting block.

[0015] By adopting the above technical solution, the pressure cylinder drives the pressure block to rotate around the shaft, thereby locking the roller shaft. This achieves the effects of supporting the middle of the roller shaft, reducing the vibration generated during the grinding process, and adapting to workpieces of different sizes.

[0016] The present invention is further configured such that: the support unit includes a support slide rail, a support slider is slidably mounted on the support slide rail, a support telescopic rod is mounted in the middle of the support slider, and the output end of the support telescopic rod is connected to the drive mechanism.

[0017] The present invention is further configured such that: the driving mechanism includes a driving motor and a transmission shaft; the driving motor is mounted on the outer wall of the support frame; a belt is fitted on the output end of the driving motor and the transmission shaft; a driving wheel is mounted on the end of the transmission shaft away from the belt; a first driven wheel is meshed above the driving wheel; a rotating shaft is mounted in the middle of the first driven wheel; a second driven wheel is mounted on the top of the rotating shaft; the second driven wheel meshes with the bottom of the first gripper and the second gripper; and the driving mechanism is mounted on the support frame.

[0018] By adopting the above technical solution, the drive motor is installed on the outer wall of the support frame, and a belt is sleeved on the output end of the drive motor and the transmission shaft. A drive wheel is installed at the end of the transmission shaft away from the belt, and a first driven wheel is meshed above the drive wheel. A rotating shaft is installed in the middle of the first driven wheel, which supports the telescopic rod and the connecting frame. The second driven wheel meshes with the bottom serrations of the first and second grippers, thereby achieving the effect of adjusting the clamping size of the roller shaft and supporting the middle part of the roller shaft when the adjustment unit is removed.

[0019] The present invention is further configured such that: the clamping unit includes a clamping base, a clamping column is installed on the clamping base, a clamping frame is installed on the clamping column, the clamping frame is irregularly shaped, and three clamping telescopic rods are equiaxially arranged in the vertical hollow part of the clamping frame. A rotating wheel is rotatably installed at the output end of the clamping telescopic rod, and a clamping plate is installed on the rotating wheel.

[0020] By adopting the above technical solution, three sets of clamping telescopic rods are set up to extend and drive the rotating wheel and clamping plate closer to the roller shaft. The rotating wheel rotates to adjust the angle of the clamping plate, and the clamping plate is attached to the outer surface of the roller shaft. Ordinary clamping is difficult to clamp workpieces with special shapes. Compared with ordinary clamping, the rotating wheel of this invention can adjust the clamping plate to achieve the effect of tightly attaching to the outer surface of the truncated cone of the roller shaft.

[0021] A grinding method for rollers, according to the grinding equipment for rollers described above, includes the following steps:

[0022] S1. First, the grinding unit clamps one end of the roller shaft, and then the clamping unit clamps the other end of the roller shaft.

[0024] S3. The grinding mechanism grinds the side wall of the roller shaft near the clamping unit.

[0025] S4. After the end of the roller shaft near the clamping unit is polished, the adjusting unit lowers to relax the support on the roller shaft, and the adjusting unit rotates to exit from the bottom of the roller shaft.

[0026] S5. After the adjustment unit exits, the support unit moves to the position after grinding and continues to rise to clamp the roller shaft, providing support from the smooth position of the roller shaft.

[0027] S6. After the support unit completes its support, the grinding mechanism continues to grind the remaining part of the roller.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting three sets of clamping telescopic rods to extend and drive the rotating wheel and clamping plate closer to the roller shaft, the rotating wheel rotates to adjust the angle of the clamping plate, and the clamping plate is attached to the outer surface of the roller shaft. Ordinary clamping is difficult to clamp workpieces with special shapes. Compared with ordinary clamping, the rotating wheel of this invention can adjust the clamping plate to achieve the effect of tightly attaching to the outer surface of the truncated cone of the roller shaft.

[0030] 2. By setting a pressure cylinder to drive the pressure block to rotate around the shaft, the roller shaft is locked, which achieves the effect of supporting the middle of the roller shaft, reducing the vibration of the roller shaft during the grinding process, and adapting to workpieces of different sizes.

[0031] 3. By setting up a support telescopic rod and a connecting frame, the second driven wheel meshes with the bottom serrations of the first and second grippers, achieving the effect of adjusting the clamping size of the roller shaft and supporting the middle of the roller shaft when the adjustment unit is removed.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0048] Please see Figure 1-10 The present invention provides the following technical solutions:

[0049] Example 1, see Figure 1A grinding device for rollers includes a grinding unit 1 for clamping and processing workpieces. A clamping unit 4 is installed at one end of the grinding unit 1 to clamp the workpiece, thereby fixing both ends of the workpiece. The grinding unit 1 includes a roller 15 and a grinding mechanism 17. The roller 15 is a special-shaped workpiece that needs to be processed. Its overall shape is a frustum, and a groove is provided in the middle part. This means that ordinary clamping cannot meet the clamping requirements of this workpiece. The grinding mechanism 17 is used to realize the grinding function in the grinding unit 1 and grind the clamped roller 15.

[0050] See Figure 2 The grinding unit 1 includes a grinding base 11, which is L-shaped. A housing 12 is installed at one end of the grinding base 11 away from the clamping unit 4. A triangular chuck 13 is installed on the housing 12. A ventilation opening 14 is also provided on the triangular chuck 13. A roller shaft 15 is clamped in the middle of the triangular chuck 13.

[0051] See Figure 2 The grinding base 11 provides an installation environment. The special shape of the grinding base 11 facilitates installation and processing of the roller shaft 15. A triangular chuck 13 is installed on the machine housing 12. The triangular chuck 13 includes a clamping element, a clamping base and a motor. The clamping element on the triangular chuck 13 can be adjusted to clamp according to the size of the roller shaft 15.

[0052] See Figure 2 The motor drives the clamping base to rotate, and the clamping member can retract relative to the clamping base to clamp the roller 15. The vent 14 is used to dissipate the heat emitted by the motor driving the triangular chuck.

[0053] See Figure 2 and Figure 3 A grinding slide rail 16 is installed on one side of the grinding base 11. A grinding slider 18 is slidably installed on the grinding slide rail 16. The grinding slider 18 is fixedly connected to the grinding mechanism 17. The grinding mechanism 17 includes a mounting plate 171. One side of the mounting plate 171 is connected to the grinding slider 18. A slide block 172 is installed on the other side of the mounting plate 171. A rotating block 173 is rotatably installed above the slide block 172. A grinding rocker arm 174 is installed on the rotating block 173.

[0054] See Figure 2 and Figure 3The grinding slide rail 16 is mounted on the grinding base 11. The grinding slider 18 can slide on the groove of the grinding slide rail 16. One side of the mounting plate 171 is connected to the grinding slider 18, and the other side of the mounting plate 171 is connected to the slide block 172. The grinding slide rail 16 drives the grinding slider 18 to slide, and the grinding slider 18 drives the slide block 172 to slide. The rotating block 173 rotates relative to the slide block 172 and synchronously drives the grinding swing arm 174 to rotate. The grinding swing arm 174 can perform grinding processing on the roller shaft 15.

[0055] See Figure 10 The clamping unit 4 includes a clamping base 41, a clamping column 42 is mounted on the clamping base 41, a clamping frame 43 is mounted on the clamping column 42, the clamping frame 43 is irregularly shaped, and three clamping telescopic rods 46 are equiaxially arranged in the vertical hollow part of the clamping frame 43. A rotating wheel 45 is rotatably mounted on the output end of the clamping telescopic rod 46, and a clamping plate 44 is mounted on the rotating wheel 45.

[0056] See Figure 10 A clamping column 42 is installed on the clamping base 41. The clamping column 42 can adjust the height of the clamping frame 43. The rotating wheel 45 can rotate at the output end of the clamping telescopic rod 46. The rotating wheel 45 rotates to adjust the angle of the clamping plate 44, so that the clamping plate 44 is tightly attached to the outer surface of the frustum of the roller shaft 15. The three sets of clamping telescopic rods 46 extend, driving the rotating wheel 45 and the clamping plate 44 to move closer to the roller shaft 15. The rotating wheel 45 rotates to adjust the angle of the clamping plate 44, and the clamping plate 44 is attached to the outer surface of the roller shaft 15, thus completing the clamping of the roller shaft 15.

[0057] See Figure 2 and Figure 10 By setting three sets of clamping telescopic rods 46 to extend and drive the rotating wheel 45 and clamping plate 44 to move closer to the roller shaft 15, the rotating wheel 45 rotates to adjust the angle of the clamping plate 44, and the clamping plate 44 fits against the outer surface of the roller shaft 15. Ordinary clamping is difficult to clamp workpieces with special shapes. Compared with ordinary clamping, the rotating wheel 45 of this invention can adjust the clamping plate 44 to achieve the effect of tightly fitting the outer surface of the frustum of the roller shaft 15.

[0058] In the second embodiment, during the grinding process of the grinding unit 1, the clamps at both ends cannot stably support the roller 15, and vibration will occur during the grinding process. This will cause the balance and uniformity of the roller 15 to be damaged, and will also cause the surface to be rough.

[0059] See Figure 3 An adjustment unit 2 is installed on one side of the grinding unit 1. The adjustment unit 2 also includes a connecting seat 21. An electric slide rail 22 is installed on the connecting seat 21. A slider 23 is slidably installed on the electric slide rail 22. A fixing block 24 is installed on the slider 23.

[0060] See Figure 3The adjustment unit 2 is used to fix the middle part after clamping at both ends to avoid vibration and friction during grinding. The connecting seat 21 is used to provide the installation environment and connect the grinding base 11. The electric slide rail 22 is used to provide sliding conditions. The slider 23 slides on the electric slide rail 22 and drives the fixing block 24 synchronously.

[0061] See Figure 4 A swing motor 25 is installed on one side of the fixed block 24. A swing plate 26 is rotatably installed on the swing motor 25. A rotating motor 27 is installed on the swing plate 26. A fixed component 29 is rotatably installed on the rotating motor 27.

[0062] See Figure 4 The swing motor 25 is divided into a swing part and a drive part. The swing part is connected to the swing plate 26. The drive part can drive the swing part to relieve the vibration force transmitted by the roller 15. The rotating motor 27 is divided into a rotating part and a rotating part. The rotating part drives the rotating part to adjust the position of the fixed component 29.

[0063] See Figure 4 and Figure 5 The fixed component 29 includes a lifting plate 291, which is rotatably mounted on a rotating motor 27. A lifting seat 292 is mounted on the lifting plate 291, which is above the rotating motor 27. A lifting cylinder 293 is mounted on the lifting seat 292. An adjusting plate 294 is mounted on the output end of the lifting cylinder 293. A pressure shaft mechanism 295 is mounted on the adjusting plate 294. The pressure shaft seat 2951 is connected to the adjusting plate 294.

[0064] See Figure 4 and Figure 5 The rotating part of the rotating motor 27 is connected to the lifting plate 291. The lifting plate 291 is used to provide the installation environment. The output end of the lifting cylinder 293 is equipped with an adjusting plate 294. The lifting cylinder 293 can drive the adjusting plate 294 to adjust its up and down position. A pressure shaft mechanism 295 is installed above the end of the adjusting plate 294 near the grinding unit 1.

[0065] See Figure 6The adjustment unit 2 includes a pressure shaft seat 2951, which provides installation conditions. A pressure shaft block 2952 is mounted on the pressure shaft seat 2951. The pressure shaft block 2952 has an irregular shape, which makes the roller 15 easier to lock and reduces vibration. A bottom mounting block 2955 is mounted on one side of the pressure shaft block 2952. A pressure shaft cylinder 2953 is rotatably mounted on the bottom mounting block 2955. A rotating shaft 2957 is rotatably set on one side of the pressure shaft block 2952. A pressure block 2956 is mounted on the rotating shaft 2957. A top mounting block 2954 is mounted on the lower part of the pressure block 2956 near the bottom mounting block 2955. The output end of the pressure shaft cylinder 2953 is hinged to the top mounting block 2954. The rotation of the rotating shaft 2957 can drive the pressure block 2956 to rotate. If roller 15 of different sizes is replaced, it can be adjusted to achieve the effect of locking roller 15 of different sizes.

[0066] See Figure 4 , Figure 5 and Figure 6 When the roller 15 is grinding, the pressure block 2952 vibrates, and the vibration force is transmitted to the adjusting plate 294. The vibration force of the adjusting plate 294 is transmitted to the lifting plate 291. The rotating motor 27 provides the first relief for the vibration transmitted at the beginning. The remaining vibration force is transmitted to the swing plate 26. The swing part of the swing motor 25 is connected to the swing plate 26. The driving part can drive the swing part to relieve the vibration force transmitted by the roller 15.

[0067] See Figure 6 The output end of the pressure cylinder 2953 retracts, causing the pressure block 2956 to rotate counterclockwise around the pivot 2957, thereby opening the pressure mechanism 295. The lifting cylinder 293 continues to lift the adjusting plate 294 until the roller 15 abuts against the pressure block 2952. The output end of the pressure cylinder 2953 extends, causing the pressure block 2956 to rotate clockwise around the pivot 2957, thereby locking the pressure mechanism 295 and thus completing the support for the roller 15.

[0068] See Figure 6 By setting the pressure cylinder 2953 to drive the pressure block 2956 to rotate around the shaft 2957, the roller shaft 15 is locked, which achieves the effect of supporting the middle part of the roller shaft 15, reducing the vibration generated by the roller shaft 15 during the grinding process, and adapting to workpieces of different sizes.

[0069] In Example 4, since the clamping part of the adjustment unit 2 needs to be polished during the grinding process, when the adjustment unit 2 is removed, the intermediate support is lost, and the grinding will still produce vibration.

[0070] See Figure 1A support unit 3 is installed above the grinding unit 1. The support unit 3 is used to support the roller shaft 15 after the adjustment unit 2 is removed.

[0071] See Figure 7 and Figure 8 The support unit 3 includes a support frame 34 for supporting the roller shaft 15, a drive mechanism 37 mounted on the support frame 34 for providing driving force, a connecting frame 38 mounted in the middle of the support frame 34 for providing an installation environment, and a first gripper 35 and a second gripper 36 on both sides of the connecting frame 38. The bottom of the first gripper 35 and the second gripper 36 are both rectangular, and the rectangular surfaces of the first gripper 35 and the second gripper 36 relative to the connecting frame 38 are both serrated.

[0072] See Figure 7 and Figure 8 The support unit 3 includes a support slide rail 31, which provides sliding conditions. A support slider 32 is slidably mounted on the support slide rail 31. The support slider 32 slides on the support slide rail 31. A support telescopic rod 33 is installed in the middle of the support slider 32. The support telescopic rod 33 can adjust the height of the support. It can be adjusted by replacing rollers 15 of different sizes. The output end of the support telescopic rod 33 is connected to the bottom of the drive mechanism 37.

[0073] See Figure 9 The drive mechanism 37 includes a drive motor 371 and a transmission shaft 373. The drive motor 371 is mounted on the outer wall of the support frame 34. A belt 372 is fitted onto the output end of the drive motor 371 and the transmission shaft 373. The rotation of the drive motor 371 synchronously drives the belt 372, which in turn drives the transmission shaft 373 to rotate. A drive pulley 374 is mounted on the end of the transmission shaft 373 away from the belt 372. A first driven pulley 375 is meshed above the drive pulley 374. The rotation of the transmission shaft 373... The drive wheel 374 rotates, which in turn drives the first driven wheel 375 to rotate. A rotating shaft 377 is installed in the middle of the first driven wheel 375, and a second driven wheel 376 is installed on the top of the rotating shaft 377. The second driven wheel 376 meshes with the bottom serrations of the first gripper 35 and the second gripper 36. The drive mechanism 37 is mounted on the support frame 34. The rotation of the first driven wheel 375 synchronously drives the rotating shaft 377 to rotate, and the rotating shaft 377 drives the second driven wheel 376 to rotate.

[0074] See Figure 9The drive motor 371 drives the drive wheel 374 to rotate via the transmission shaft 373. The drive wheel 374 drives the first driven wheel 375 to rotate. The rotation of the first driven wheel 375 drives the rotating shaft 377 to rotate, which in turn drives the second driven wheel 376 to rotate. The rotation of the second driven wheel 376 causes the first gripper 35 and the second gripper 36 to move out of alignment, so that the upper gripper portions of the first gripper 35 and the second gripper 36 are brought closer together to clamp the roller shaft 15.

[0075] See Figure 9 By setting the support telescopic rod 33 and the connecting frame 38 to cooperate, the second driven wheel 376 engages with the bottom serrations of the first gripper 35 and the second gripper 36, thereby achieving the effect of adjusting the clamping size of the roller shaft 15 and supporting the middle part of the roller shaft 15 when the adjustment unit 2 is removed.

[0076] Example 4: A grinding method suitable for rollers, according to the above-mentioned grinding equipment suitable for rollers, includes the following steps:

[0077] S1. First, one end of the roller shaft 15 is clamped by the grinding unit 1, and then the other end of the roller shaft 15 is clamped by the clamping unit 4.

[0078] More specifically, the steps are as follows: S11, the clamping parts on the triangular chuck 13 are adjusted and clamped according to the size of the roller 15.

[0079] S12. The extension of the three sets of telescopic rods drives the rotating wheel 45 and the clamping telescopic rod 46 to move closer to the roller shaft 15. The rotating wheel 45 rotates to adjust the angle of the clamping telescopic rod 46, and the clamping telescopic rod 46 fits against the outer surface of the roller shaft 15 to complete the clamping of the roller shaft 15.

[0080] S2. After the roller shaft 15 is clamped, the adjusting unit 2 rises and contacts the bottom of the roller shaft 15 to support the roller shaft 15.

[0081] More specific steps are as follows: 21. After the roller 15 completes clamping, the lifting cylinder 293 lifts the adjusting plate 294 to reach the clamping height of the roller 15.

[0082] S22, the output end of the pressure cylinder 2953 retracts, causing the pressure block 2956 to rotate counterclockwise around the pivot point of the rotating shaft 2957, thereby opening the pressure mechanism 295. The lifting cylinder 293 continues to lift the adjusting plate 294 until the roller shaft 15 abuts against the pressure block 2952.

[0083] S23, the output end of the pressure cylinder 2953 extends out, driving the pressure block 2956 to rotate clockwise around the pivot point of the rotating shaft 2957, thereby locking the pressure mechanism 295 and thus providing support for the roller shaft 15.

[0084] S3, Grinding mechanism 17 grinds the side wall of roller shaft 15 near the clamping unit 4.

[0085] More specific steps are as follows: S31, the grinding slide rail 16 drives the grinding slider 18 to slide near the clamping unit 4, the grinding slider 18 drives the slide block 172 to slide, and the rotating block 173 rotates relative to the slide block 172, synchronously driving the grinding swing arm 174 to rotate.

[0086] S33. The sandpaper wound on the grinding lever 174 grinds the side wall of the roller shaft 15 near the clamping unit 4.
