Description
Technical Field
[0001] This invention relates to the field of bearing grinding technology, and more specifically to processing equipment for synchronous grinding of the inner and outer rings of motorcycle clutch bearings. Background Technology
[0002] Motorcycle clutch bearings are key components in motorcycle transmission systems. Their function is to ensure the smooth transmission of power during clutch engagement and disengagement. The machining accuracy of the inner and outer rings of the bearing directly affects the assembly accuracy, operational stability, and service life of the clutch. As the motorcycle industry develops towards higher speeds and higher power, increasingly higher requirements are placed on the dimensional accuracy, roundness, coaxiality, and surface roughness of the inner and outer rings of the clutch bearing. In the existing technology, the grinding of the inner and outer rings of the bearing is usually carried out in steps, that is, the outer ring is ground first, and then the inner ring is ground, or one end face is machined first and then the other end face is machined. However, this solution can only process the outer ring, while the inner ring still needs to be clamped and processed separately. Another technical solution discloses a bearing inner and outer ring grinding device, which achieves synchronous processing of the inner and outer rings by placing a bearing between the inner and outer grinding discs and driving the bearing to rotate. However, this type of device mainly achieves grinding by the relative movement of the bearing itself and the fixed grinding disc, which has poor adaptability to bearings of different specifications and the grinding disc is inconvenient to replace. Therefore, we propose a processing equipment for synchronous grinding of the inner and outer rings of motorcycle clutch bearings to solve the above problems. Summary of the Invention
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a processing equipment for synchronous grinding of the inner and outer rings of a motorcycle clutch bearing, so as to solve the problems existing in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a processing equipment for synchronous grinding of the inner and outer rings of a motorcycle clutch bearing, comprising a mounting plate, wherein the mounting plate is provided with an outer ring grinding assembly and a grinding worktable, the grinding worktable comprising a support platform, a turntable assembly rotatably sleeved on the support platform and a stepper motor, wherein the turntable assembly has a turntable for placing the inner and outer rings of the bearing; The stepper motor drive end is connected to an inner ring grinding assembly, which includes an intermediate shaft, a cavity shell fixed to the side of the intermediate shaft, a grinding block slidably sleeved in the cavity shell, and a spring connecting the grinding block and the intermediate shaft. A deflection tube is rotatably connected to the top of the intermediate shaft, and a movable rod is slidably sleeved inside the deflection tube. A rectangular shell is fixedly connected to the end of the movable rod. Movable pins are slidably connected to the upper and lower parts of the rectangular shell, and a grinding plate is fixedly connected to the end of the movable pin. The inner ring grinding assembly also includes a conical block that is slidably sleeved in another cavity. Fan blades are fixed on both sides of the conical block. When the intermediate shaft rotates, the grinding block and grinding plate extend outward against the spring force under the action of centrifugal force to clamp and grind the inner ring of the bearing. The cone block rotates with the intermediate shaft to scrape off the grinding dust, and the fan blades rotate to generate airflow to remove the dust; the fan blades and the front end of the cone block form a 90° angle.
[0005] Furthermore, the outer ring grinding assembly includes a DC brushless motor, a motor shaft fixed to the motor drive end, and a grinding head fixed to the bottom end of the motor shaft. A sleeve block is rotatably sleeved on the side of the motor shaft, and one side of the sleeve block is fixed to the end of the suspension plate on the mounting plate.
[0006] Furthermore, the turntable assembly also includes a ring tube fixed to the bottom of the turntable and a speed reduction gear fixedly sleeved inside the ring tube, the inner side of which is fixedly sleeved to the side of the inner ring grinding assembly.
[0007] Furthermore, the speed reduction gear includes a gear ring, three traveling gears, one constant gear, and three support shafts. The constant gear meshes with the traveling gears, the traveling gears mesh with the gear ring, the gear ring is fixed to the inner side of the ring tube, and the constant gear is fixed to the side of the intermediate shaft.
[0008] Furthermore, there are four cavities in total, three of which have grinding blocks slidingly fitted inside, and the other cavity has a conical block slidingly fitted inside. The tail of both the grinding block and the conical block is provided with a limiting flange, and the opening end of the cavity is provided with a matching limiting step.
[0009] Furthermore, the outer surface of the grinding block is an arc surface that matches the inner wall of the bearing inner ring and is provided with a grinding layer; the front end of the cone block is cone-shaped with a cone angle of 60°-90°, and the outer surface of the cone block is provided with a scraping blade.
[0010] Furthermore, the bottom ends of the two deflection tubes are rotatably connected to the top of the intermediate shaft via a hinge seat. The deflection tubes can deflect 0°-90° in the horizontal direction around the hinge seat. The tube walls of the deflection tubes are provided with locking screws for fixing the extension length of the movable rod.
[0011] Furthermore, the grinding plate is an arc-shaped plate with its arc-shaped surface matching the outer wall of the bearing inner ring or the inner wall of the bearing outer ring and having a grinding layer. The rectangular shell has a compression spring inside that abuts against the end of the movable pin.
[0012] Furthermore, the airflow generated by the rotation of the fan blades along the intermediate shaft carries away and discharges the dust generated during the grinding of the inner ring of the grinding block and the grinding of the grinding plate.
[0013] Furthermore, four rectangularly distributed machine tool legs are fixed to the bottom of the mounting plate, and the machine tool legs include rubber pads and adjusting bolts; The surface of the slide rail is hardened and coated with lubricating grease; The cylinder is a double-acting cylinder. The two cylinders are controlled to extend and retract synchronously by an electromagnetic reversing valve so that the two outer ring grinding components can clamp or release the outer ring of the bearing synchronously from both sides.
[0014] The technical effects and advantages of this invention are as follows: 1. Place the inner and outer rings of the bearing together on the turntable. Move the connecting table using a cylinder to bring the two grinding heads closer together, eventually clamping the outer ring. Then, bend the deflection tube horizontally, placing the grinding plate between the inner and outer rings. Turn on the stepper motor, and under centrifugal force, the grinding block and grinding plate move outward to clamp the inner ring, thus fixing it in place. Grind the inner ring simultaneously. Then, using the turntable assembly, drive the turntable to rotate via the intermediate shaft. At this time, the inner and outer rings rotate under the rotation of the turntable. The grinding heads and grinding plates grind the outer and inner sides of the outer ring respectively, while the grinding plate and grinding block at the other end grind the outer and inner sides of the inner ring simultaneously. This avoids the problem of poor adaptability to different bearing specifications, which necessitates changing the grinding plate.
[0015] 2. The cone block rotates with the central shaft, scraping off the inner side of the inner ring of the grinding block's grinding dust. The airflow generated by the rotation of the fan blades carries away the grinding dust from the inner and outer rings, preventing dust accumulation in the grinding area. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The processing equipment for synchronous grinding of the inner and outer rings of motorcycle clutch bearings involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Reference Figure 1 This invention provides a processing device for synchronous grinding of the inner and outer rings of a motorcycle clutch bearing, comprising a mounting plate 1, a machine tool leg fixedly connected to the bottom of the mounting plate 1, two slide rails 101 fixedly connected to the top of the mounting plate 1, the two slide rails 101 being arranged facing each other, cylinders 102 fixedly connected to both ends of the top of the mounting plate 1, a moving table 103 fixedly connected to the driving end of each of the two cylinders 102, a connecting table 104 fixedly connected to the top of each of the two moving tables 103, a suspension plate 105 fixedly connected to one side of each of the two connecting tables 104, and an outer ring grinding assembly 2 fixedly connected to one end of each of the two suspension plates 105, a grinding worktable 3 fixedly connected to the middle of the top of the mounting plate 1, and the two outer ring grinding assemblies 2 being located above the grinding worktable 3.
[0020] In this embodiment, it is necessary to further explain that the machine tool legs at the bottom of the mounting plate 1 are preferably four rectangularly distributed shock-absorbing legs. Each shock-absorbing leg includes a rubber pad and an adjusting bolt. The level of the mounting plate 1 can be adjusted by rotating the adjusting bolt to ensure the stable operation of the equipment during the grinding process. The two slide rails 101 are arranged in parallel and are consistent with the length direction of the mounting plate 1. The moving table 103 is slidably sleeved on the slide rail 101. The surface of the slide rail 101 is quenched and coated with lubricating grease to reduce the frictional resistance when the moving table 103 slides. The two cylinders 102 are both double-acting cylinders. Their air inlets and outlets are connected to an external air source and an electromagnetic reversing valve through air pipes, respectively. The switching of the electromagnetic reversing valve controls the two cylinders 102 to extend or retract synchronously, thereby ensuring that the two outer ring grinding components 2 can synchronously approach or move away from the outer ring of the bearing from both sides to achieve precise centering and clamping. The connecting table 104 and the moving table 103, and the suspension plate 105 and the connecting table 104 are all fixedly connected by bolts to facilitate the disassembly and replacement of parts.
[0021] Reference Figure 2 The outer ring grinding assembly 2 includes a DC brushless motor 201. The drive end of the DC brushless motor 201 is fixedly connected to a motor shaft 202. The bottom end of the motor shaft 202 is fixedly connected to a grinding head 203. A sleeve block is rotatably sleeved on the side of the motor shaft 202. One side of the sleeve block is fixedly connected to one end of the suspension plate 105.
[0022] In this embodiment, it is necessary to further explain that the DC brushless motor 201 is preferably a DC brushless motor with a rated speed of 3000-6000 rpm. It is equipped with heat dissipation fins on the outside to facilitate heat dissipation during long-term continuous operation. The grinding head 203 is a detachable structure with an internal threaded hole at its top. The bottom end of the motor shaft 202 is equipped with an external thread that matches it. The grinding head 203 is fixed to the bottom end of the motor shaft 202 by threaded connection and is secured with a lock nut to prevent loosening. The outer circumference of the grinding head 203 is provided with a spiral chip removal groove, which can guide the generated chips along the spiral groove during grinding to avoid chip blockage affecting the grinding effect. The material of the grinding head 203 is preferably cubic boron nitride (CBN) or diamond grinding wheel, selected according to the material and hardness of the bearing outer ring. The sleeve is equipped with a rolling bearing. The motor shaft 202 is rotatably connected to the sleeve through the rolling bearing to reduce friction and vibration when the motor shaft 202 rotates.
[0023] Reference Figures 3 to 5 The grinding worktable 3 includes a support platform 301. The bottom of the support platform 301 is fixedly connected to the middle of the top of the mounting plate 1. A turntable assembly 302 is rotatably sleeved on the top of the support platform 301. A stepper motor 303 is fixedly connected to the middle of the bottom of the mounting plate 1, and the driving end of the stepper motor 303 passes through the mounting plate 1. An inner ring grinding assembly 304 is fixedly connected to the driving end of the stepper motor 303.
[0024] In this embodiment, it should be specifically noted that the support platform 301 is a hollow cylindrical structure with a bearing seat inside. The turntable assembly 302 is rotatably sleeved on the top of the support platform 301 via the bearing. The stepper motor 303 is preferably a hybrid stepper motor, whose drive end is fixedly connected to the intermediate shaft 3041 of the inner ring grinding assembly 304 via a coupling. The stepper motor 303 is externally connected to a stepper motor driver, which controls the speed and direction of the stepper motor 303 through pulse signals. Different speeds can be set according to the grinding process requirements.
[0025] Reference Figure 6 The turntable assembly 302 includes a turntable 3021, with a ring tube 3022 fixedly connected to the bottom of the turntable 3021. A speed reduction gear 3023 is fixedly sleeved on the inner side of the ring tube 3022, and an inner ring grinding assembly 304 is fixedly sleeved on the inner side of the speed reduction gear 3023. The speed reduction gear 3023 consists of a gear ring, three traveling gears, a constant gear, and a three-shaft bracket. The constant gear meshes with the three traveling gears. The bottom of the three traveling gears is rotatably connected to the speed reduction gear 3023. The inner side of the speed reduction gear 3023 is rotatably sleeved on the side of the inner ring grinding assembly 304, and the side of the inner ring grinding assembly 304 is fixedly sleeved with the inner side of the constant gear. The three traveling gears mesh with the gear ring, and the gear ring is fixedly sleeved on the inner side of the ring tube 3022.
[0026] In this embodiment, it should be specifically noted that the reduction ratio of the speed-reducing gear 3023 is preferably 3:1 to 5:1. That is, when the stepper motor 303 drives the constant gear to rotate, the gear ring and the ring tube 3022 and the turntable 3021, which are fixedly connected to it, rotate at a lower speed through the transmission of the traveling gear, thereby realizing the speed reduction and torque increase of the turntable 3021. The three traveling gears are evenly distributed around the constant gear, spaced 120° apart, and their relative positions are kept constant by three support shafts to ensure even load distribution and smoother transmission. The bottom of the three support shafts is rotatably supported inside the bearing platform 301 by thrust bearings to bear the axial load transmitted by the turntable 3021 and the bearing workpiece. A sealing ring is provided between the outer wall of the ring tube 3022 and the bearing platform 301 to prevent dust generated during grinding from entering the interior of the speed-reducing gear 3023 and causing wear.
[0027] Reference Figures 7 to 9The inner ring grinding assembly 304 includes an intermediate shaft 3041. The side of the intermediate shaft 3041 is rotatably sleeved on the inner side of the turntable 3021. Four cavity shells 3042 are fixedly connected to the side of the top end of the intermediate shaft 3041. Grinding blocks 3043 are slidably sleeved on the inner side of three of the cavity shells 3042, and a conical block 3044 is slidably sleeved on the inner side of the other cavity shell 3042. Fan blades 3045 are fixedly connected to both sides of the conical block 3044, and the fan blades 3045 and the front end of the conical block 3044 form an angle of 90°. One side of the grinding block 3043 and the conical block 3044... Each end is fixedly connected to a spring, and one end of the spring is fixedly connected to the side of the intermediate shaft 3041. The top end of the intermediate shaft 3041 is rotatably connected to two deflection tubes 3046. The inner side of the two deflection tubes 3046 is slidably sleeved with a movable rod 3047. The sides of the two movable rods 3047 are fixedly connected to fixed plates. One end of each of the two fixed plates is fixedly connected to a rectangular shell 3048. The top and bottom of the two rectangular shells 3048 are slidably sleeved with four movable pins, and the movable pins at the top and bottom of the rectangular shells 3048 are fixedly connected to grinding plates 3049.
[0028] In this embodiment, it is necessary to further explain that the cavity shell 3042 is a rectangular hollow shell, and its inner wall is polished to reduce the friction when the grinding block 3043 and the cone block 3044 slide. The tail of the grinding block 3043 and the cone block 3044 are provided with limiting flanges. The opening end of the cavity shell 3042 is provided with a limiting step that cooperates with the limiting flange to prevent the grinding block 3043 and the cone block 3044 from detaching from the cavity shell 3042 under the action of centrifugal force. The stiffness of the spring is selected according to the speed of the stepper motor 303. When the speed of the stepper motor 303 is low, the restoring force of the spring causes the grinding block 3043 and the cone block 3044 to retract into the cavity shell 3042. When the stepper motor 303 speed increases to the set value, the centrifugal force overcomes the spring force, causing the grinding block 3043 and the cone block 3044 to extend outward and contact the inner ring of the bearing, thereby realizing automatic clamping and grinding. The outer surface of the grinding block 3043 is an arc surface that matches the inner wall of the bearing inner ring. A grinding layer is provided on the arc surface. The grinding layer is preferably electroplated diamond or cubic boron nitride abrasive grains. The front end of the cone block 3044 is cone-shaped, and its cone angle is preferably 60°-90°. The outer surface of the cone block 3044 is provided with a scraping blade to scrape off the dust generated when the grinding block 3043 grinds the inner side of the inner ring.
[0029] The bottom ends of two deflection tubes 3046 are rotatably connected to the top end of the intermediate shaft 3041 via hinge seats. The deflection tubes 3046 can deflect horizontally from 0° to 90° around the hinge seats. A movable rod 3047 is slidably sleeved inside the deflection tubes 3046. Locking screws are provided on the walls of the deflection tubes 3046. When the movable rod 3047 extends to the required length, it can be fixed inside the deflection tubes 3046 by the locking screws, thereby adjusting the radial position of the grinding plate 3049 to accommodate the clearance width between the inner and outer rings of bearings of different sizes. One end of each movable pin is fixedly connected to the grinding plate 3049, and the other end of the movable pin is provided with a limit cap to prevent it from dislodging. The grinding plate 3049 is an arc-shaped plate whose arc-shaped surface matches the outer wall of the bearing inner ring or the inner wall of the outer ring. A grinding layer is provided on the arc-shaped surface of the grinding plate 3049. The rectangular shell 3048 is equipped with a compression spring inside. The two ends of the compression spring abut against the inner wall of the rectangular shell 3048 and the end of the movable pin, respectively. Under the action of centrifugal force, the movable pin drives the grinding plate 3049 to extend outward, so that the grinding plate 3049 fits against the outer wall of the inner ring or the inner wall of the outer ring for grinding.
[0030] The working principle of this invention is as follows: The inner and outer rings of the bearing are placed together on the turntable 3021 of the turntable assembly 302. The cylinders 102 on both sides are activated to drive the connecting platform 104 to move, so that the grinding heads 203 of the two outer ring grinding assemblies 2 move closer to each other and clamp the outer ring of the bearing from the outside. The deflection tube 3046 is bent horizontally so that the grinding plate 3049 is placed in the gap between the inner and outer rings. Then, the stepper motor 303 is activated. Under the action of centrifugal force, the grinding block 3043 and the grinding plate 3049 move outward and clamp the inner ring of the bearing from the inside, thereby fixing the inner ring and preparing it for grinding. The intermediate shaft 3041 of the inner ring grinding assembly 304 is driven by the stepper motor 303, which in turn drives the turntable 3021 to rotate through the speed reduction gear 3023 of the turntable assembly 302. The clamped inner and outer rings rotate under the drive of the turntable 3021. The rotating outer ring contacts the grinding heads 203 of the outer ring grinding assembly 2 on both sides, grinding the outer and inner sides of the outer ring. The rotating inner ring contacts the grinding plate 3049 and grinding block 3043 of the inner ring grinding assembly 304, grinding the inner and outer sides of the inner ring. This process enables the inner and outer rings to complete the grinding of all surfaces simultaneously in one clamping, avoiding the problems of step-by-step processing and frequent grinding disc replacement. During grinding, the intermediate shaft 3041 rotates, causing the conical block 3044 to rotate, scraping off the dust generated by the grinding block 3043 grinding the inner side of the inner ring. At the same time, the fan blades 3045 on both sides of the conical block 3044, which are at a 90° angle, generate airflow as the intermediate shaft rotates, which picks up and discharges the dust generated by grinding the inner and outer rings, effectively preventing the accumulation of dust in the grinding area and ensuring processing accuracy and surface quality.
