Description

A motor shaft surface grinding device Technical Field

[0001] This invention relates to the field of motor shaft technology, and in particular to a motor shaft surface grinding device. Background Technology

[0002] Electric motors are widely used in many fields. Before the motor shaft is installed on the motor, it needs to be surface-polished to make its surface meet the usage conditions and avoid impurities such as burrs on its surface from affecting the accuracy of use.

[0003] However, traditional grinding equipment is usually installed manually, with one end of the motor shaft held by a clamping mechanism and the other end held in place by a contact seat. Then, grinding is performed using grinding rollers or sandpaper. First, manual installation results in a long preparation time for grinding the motor shaft, which is not conducive to the efficiency of batch grinding of motor shafts. Second, after the motor shaft is fixed, one end is held in place by the contact seat. When the grinding equipment approaches the motor shaft at the contact seat end, the motor shaft is prone to positional displacement during the grinding process, affecting the final grinding accuracy. Therefore, this invention proposes a motor shaft surface grinding device. Summary of the Invention

[0004] The main objective of this invention is to provide a grinding device for the surface of a motor shaft, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A grinding device for the surface of a motor shaft includes a worktable, a contact seat, a clamping mechanism, a drive mechanism, and two mounting plates, with a grinding structure disposed between the two mounting plates;

[0007] The grinding structure includes two limiting rings, two fixing rings, two gear rings, three connecting plates, one grinding roller, two limiting rollers, two fixing plates, and one gear transmission component. The limiting rings have three sliding holes on their outer surfaces. Slider blocks are fixedly installed at both ends of the connecting plates. The gear rings act on the sliders, causing them to slide within the sliding holes of the corresponding limiting rings, thus enabling the grinding roller and the two limiting rollers to synchronously contract and expand. The gear rings and the gear transmission component are meshed together. A shelf is fixedly connected to the outside of the connecting plates via several guide rods. One shelf has a fixing plate on its outer surface, and a motor is mounted on the outer surface of the fixing plate. The output shaft of the motor passes through the fixing plate and is fixedly connected to a rotating wheel. The rotating wheel is connected to the rotating wheel via a belt, and the rotating wheel is fixedly connected to the grinding roller.

[0008] As a preferred embodiment of the present invention, a crossbar is fixedly connected between two mounting plates, and a horizontal tube is fixedly connected to the crossbar through several connecting brackets. A connector and several nozzles are provided on the outside of the horizontal tube.

[0009] As a preferred technical solution of the present invention, a water tank and a water pump are fixedly installed on the outside of the workbench. A connecting pipe one and a connecting pipe two are installed on the outside of the water pump. One end of the connecting pipe one passes through the workbench and the water tank and is fixedly connected. Before use, a water pipe is connected between the connecting pipe two and the connector. Several drainage holes are opened on the top of the workbench. The water sprayed from the nozzle flows back into the water tank from the drainage holes of the workbench.

[0010] As a preferred embodiment of the present invention, the abutment seat is disposed outside one of the mounting plates, and the clamping mechanism and the driving mechanism are disposed outside the other mounting plate. The driving mechanism acts on the clamping mechanism to rotate as a whole, and the clamping mechanism clamps one end of the motor shaft, while the other end of the motor shaft is abutted by the abutment seat.

[0011] As a preferred technical solution of the present invention, the limiting ring, the fixing ring and the corresponding fixed mounting plate are fixedly connected, the gear ring and the fixing ring are rotatably connected, one of the shelves is penetrated by the grinding roller, and the other two shelves are penetrated by the two limiting rollers respectively.

[0012] As a preferred embodiment of the present invention, the second fixing plate and the mounting plate are fixedly connected, the two second fixing plates are penetrated by a gear transmission component, and the gear transmission component is fixedly connected to the output shaft of the second motor.

[0013] As a preferred embodiment of the present invention, a feeding structure is provided on the top of the workbench. The feeding structure includes a mounting frame 1, which is fixedly connected to the workbench. A motor 3 is provided on the outside of the mounting frame 1, and the output shaft of the motor 3 passes through the mounting frame 1 and is fixedly connected to a fixing rod. The fixing rod is rotatably disposed on the inside of the mounting frame 1. Several storage trays are fixedly disposed on the outside of the fixing rod, and four storage slots are opened on the outside of the storage trays. The storage slots are used to store motor shafts. A multi-stage electric telescopic rod is fixedly disposed on the outside of the mounting frame 1 through a fixing frame. A push plate is fixedly disposed at one end of the multi-stage electric telescopic rod. The multi-stage electric telescopic rod acts on the push plate to push the motor shaft located at the corresponding position on the storage tray toward the contact seat.

[0014] As a preferred technical solution of the present invention, the feeding structure further includes a feeding assembly, which includes a second mounting frame. The second mounting frame is fixedly connected to the worktable. A feeding box is fixedly installed on the outside of the second mounting frame, and the feeding box is fixedly connected to an arc plate by several stiffeners. The arc plate acts on the storage tray, thereby realizing the stability of the motor shaft during the rotation of the storage tray.

[0015] As a preferred embodiment of the present invention, the top of the workbench is provided with a material unloading buffer structure. The material unloading buffer structure includes a first mounting frame, a second mounting frame, a movable rod, several base plates, several buffer plates, and several springs. The first mounting frame, the second mounting frame, and the base plates are all fixedly connected to the workbench. The movable rod and the second mounting frame are slidably connected through each other. The two ends of the buffer plates are respectively penetrated by the first mounting frame and the movable rod. The springs are disposed between the buffer plates and the base plates.

[0016] As a preferred embodiment of the present invention, an inclined plate is fixedly installed on the top of the workbench, and two baffles are fixedly installed on the outside of the inclined plate. The inclined plate, together with the buffer plate, guides the motor shaft that has completed the grinding process for unloading.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a grinding structure, the equipment can ensure the stability of the motor shaft during the grinding process and prevent the motor shaft from shifting. During the grinding process, the limiting roller is also in close contact with the surface of the motor shaft to limit it. At the same time, before the grinding starts, the limiting roller provides limiting support for the motor shaft. After the grinding is completed, the grinding roller and the limiting roller can move synchronously to allow the ground motor shaft to fall out from the gap between two adjacent limiting rollers, avoiding the manual unloading process and saving manpower.

[0019] 2. By setting up a water pump in conjunction with the nozzle, the water in the tank is pumped into the horizontal pipe under the action of the water pump, and finally sprayed onto the surface of the motor shaft through the nozzle. This can cool down the grinding roller and the motor shaft during the grinding process. The drainage holes opened in the worktable are conducive to collecting the water sprayed by the nozzle back into the water tank during this process, which is beneficial to water recycling.

[0020] 3. By setting up a feeding structure in conjunction with a grinding structure, the motor shaft does not need to be manually fed and fixed, saving manpower and improving automation. This helps to improve the grinding efficiency of the equipment. The multi-stage electric telescopic rod acts on the push plate to push the motor shaft into the working range of the grinding structure, thereby clamping and fixing the motor shaft for grinding. The tray rotates under the action of the motor, which can rotate the motor shaft to the predetermined position, facilitating the pushing work of the multi-stage electric telescopic rod.

[0021] 4. By setting up a feeding component in conjunction with a feeding structure, it is beneficial to accurately feed the motor shaft and ensure that the motor shaft will not fall off during the rotation of the tray. The arc plate plays a role in limiting and protecting the motor shaft.

[0022] 5. By setting up a material unloading buffer structure in conjunction with the grinding structure, it is beneficial to guide the motor shaft to unload after the grinding work is completed. The spring and buffer plate can buffer the impact force generated by the falling motor shaft, avoid direct contact between the motor shaft and the worktable and cause damage, and help to improve the service life of the equipment.

[0023] 6. By setting up inclined plates, baffles and buffer plates, it is beneficial to guide the motor shaft after the grinding work is completed. With the help of external collection equipment, the motor shaft can eventually roll down to the collection equipment and be collected. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] As shown in Figures 1-15, a motor shaft surface polishing device includes a worktable 1, a contact seat 3, a clamping mechanism 4, a driving mechanism 5, two mounting plates 2, and a polishing structure 6 is provided between the two mounting plates 2.

[0042] The grinding structure 6 includes two limiting rings 9, two fixing rings 10, two gear rings 11, three connecting plates 12, one grinding roller 16, two limiting rollers 17, two fixing plates 23, and one gear transmission component 24. Three sliding holes are provided on the outside of the limiting rings 9. Slider blocks 13 are fixedly installed at both ends of the connecting plates 12. The gear rings 11 act on the sliders 13 to slide within the sliding holes of the corresponding limiting rings 9, thus enabling the grinding roller 16 and the two limiting rollers 17 to move synchronously. The device has contraction and expansion movements, and the gear ring 11 and gear transmission component 24 are meshed and connected. The outside of the connecting plate 12 is fixedly connected to a shelf 15 via several guide rods 14. One shelf 15 is provided with a fixing plate 19 on its outside. A motor 20 is provided on the outside of the fixing plate 19. The output shaft of the motor 20 passes through the fixing plate 19 and is fixedly connected to a rotating wheel 21. The rotating wheel 21 is connected to a rotating wheel 18 via a belt 22. The rotating wheel 18 is fixedly connected to the grinding roller 16.

[0043] The grinding structure 6 ensures the stability of the motor shaft during the grinding process, preventing it from shifting. During grinding, the limiting roller 17 also closely adheres to the surface of the motor shaft to limit its movement. Before grinding begins, the limiting roller 17 provides support and limit the motor shaft. After grinding is complete, the grinding roller 16 and the limiting roller 17 can move synchronously to allow the ground motor shaft to fall through the gap between two adjacent limiting rollers 17, eliminating the need for manual unloading and saving manpower.

[0044] In this embodiment, a crossbar 26 is fixedly connected between two mounting plates 2. The crossbar 26 is fixedly connected to a horizontal tube 28 through several connecting brackets 27. A connector 29 and several nozzles 30 are provided on the outside of the horizontal tube 28.

[0045] The nozzle 30 sprays water onto the surface of the motor shaft, which can cool down the grinding roller 16 and the motor shaft during the grinding process.

[0046] In this embodiment, a water tank 31 and a water pump 32 are fixedly installed on the outside of the workbench 1. A connecting pipe 33 and a connecting pipe 34 are installed on the outside of the water pump 32. One end of the connecting pipe 33 passes through the workbench 1 and the water tank 31 and is fixedly connected. Before use, a water pipe is connected between the connecting pipe 34 and the connector 29. Several drainage holes are opened on the top of the workbench 1. The water sprayed from the nozzle 30 flows back into the water tank 31 from the drainage holes of the workbench 1.

[0047] Under the action of the water pump 32, the water in the water tank 31 is pumped into the horizontal pipe 28, and finally sprayed onto the surface of the motor shaft through the nozzle 30. The drainage hole opened in the workbench 1 is conducive to collecting the water sprayed by the nozzle 30 back into the water tank 31 during this process, which is beneficial to water recycling.

[0048] In this embodiment, the abutment seat 3 is disposed outside one of the mounting plates 2, and the clamping mechanism 4 and the driving mechanism 5 are disposed outside the other mounting plate 2. The driving mechanism 5 acts on the clamping mechanism 4 to rotate as a whole, and the clamping mechanism 4 clamps one end of the motor shaft, while the other end of the motor shaft is abutted by the abutment seat 3.

[0049] The drive mechanism 5 acts on the clamping mechanism 4, causing the motor shaft to rotate as a whole.

[0050] In this embodiment, the limiting ring 9, the fixing ring 10 and the corresponding fixed mounting plate 2 are fixedly connected, the gear ring 11 and the fixing ring 10 are rotatably connected, one of the shelves 15 is penetrated by the grinding roller 16, and the other two shelves 15 are penetrated by the two limiting rollers 17 respectively.

[0051] The limiting roller 17, together with the grinding roller 16, provides limiting constraints on the motor shaft.

[0052] In this embodiment, the second fixing plate 23 and the mounting plate 2 are fixedly connected. The two fixing plates 23 are penetrated by the gear transmission component 24, and the gear transmission component 24 is fixedly connected to the output shaft of the second motor 25.

[0053] Motor 25 acts on gear transmission component 24 and gear ring 11 to mesh, thereby causing grinding roller 16 and limiting roller 17 to synchronously contract and expand.

[0054] In this embodiment, a feeding structure 7 is provided on the top of the workbench 1. The feeding structure 7 includes a mounting frame 35, which is fixedly connected to the workbench 1. A motor 36 is provided on the outside of the mounting frame 35, and the output shaft of the motor 36 passes through the mounting frame 35 and is fixedly connected to a fixing rod 37. The fixing rod 37 is rotatably disposed on the inside of the mounting frame 35. Several storage trays 38 are fixedly disposed on the outside of the fixing rod 37, and four storage slots are opened on the outside of the storage trays 38. The storage slots are used to store motor shafts. A multi-stage electric telescopic rod 40 is fixedly disposed on the outside of the mounting frame 35 through a fixing frame 39. A push plate 41 is fixedly disposed on one end of the multi-stage electric telescopic rod 40. The multi-stage electric telescopic rod 40 acts on the push plate 41 to push the motor shaft located at the corresponding position on the storage tray 38 toward the contact seat 3.

[0055] The feeding structure 7, in conjunction with the grinding structure 6, eliminates the need for manual feeding and fixing of the motor shaft, saving manpower and improving automation. This enhances the grinding efficiency of the equipment. The multi-stage electric telescopic rod 40 acts on the push plate 41, pushing the motor shaft into the working range of the grinding structure 6, whereby the motor shaft is clamped, fixed, and ground. The storage tray 38 rotates under the action of the motor 36, rotating the motor shaft to a predetermined position to facilitate the pushing operation of the multi-stage electric telescopic rod 40.

[0056] In this embodiment, the feeding structure 7 also includes a feeding component, which includes a second mounting frame 42. The second mounting frame 42 is fixedly connected to the workbench 1. A feeding box 43 is fixedly installed on the outside of the second mounting frame 42, and an arc plate 45 is fixedly connected to the feeding box 43 through several stiffeners 44. The arc plate 45 acts on the storage tray 38, thereby realizing the stability of the motor shaft during the rotation of the storage tray 38.

[0057] The feeding component, together with the feeding structure 7, can accurately feed the motor shaft and ensure that the motor shaft will not fall off during the rotation of the tray 38. The arc plate 45 plays a role in limiting and protecting the motor shaft.

[0058] In this embodiment, a material unloading buffer structure 8 is provided on the top of the workbench 1. The material unloading buffer structure 8 includes a first mounting frame 46, a second mounting frame 47, a movable rod 48, several base plates, several buffer plates 49, and several springs 50. The first mounting frame 46, the second mounting frame 47, and the base plates are all fixedly connected to the workbench 1. The movable rod 48 and the second mounting frame 47 are slidably connected through each other. The two ends of the buffer plate 49 are respectively penetrated by the first mounting frame 46 and the movable rod 48. The springs 50 are disposed between the buffer plate 49 and the base plate.

[0059] The unloading buffer structure 8, together with the grinding structure 6, can guide the motor shaft to unload after the grinding work is completed. The spring 50, together with the buffer plate 49, can buffer the impact force generated by the falling motor shaft, avoid direct contact between the motor shaft and the worktable 1, and prevent it from being damaged, which helps to improve the service life of the equipment.

[0060] In this embodiment, a sloping plate 51 is fixedly installed on the top of the workbench 1, and two baffles 52 are fixedly installed on the outside of the sloping plate 51. The sloping plate 51, together with the buffer plate 49, guides the motor shaft that has completed grinding to unload the material.

[0061] The inclined plate 51 and baffle 52, together with the buffer plate 49, can guide the motor shaft after the grinding work is completed. With the help of the external collection device, the motor shaft can finally roll down to the collection device and be collected.

[0062] It should be noted that the present invention is a motor shaft surface grinding device. Before use, the device is placed in the required location. Before use, a water pipe is connected between the connecting pipe 2 34 and the connecting head 29. A collection device is installed on the workbench 1 near the inclined plate 51 to collect the ground motor shaft, so that it can meet the operating conditions.

[0063] Several motor shafts are placed in the feeding box 43, causing the motor shafts to roll into the corresponding storage slots of the storage tray 38. The third motor 36 is started, causing the fixing rod 37 to rotate 90 degrees with several storage trays 38 and then stop. At this time, the centers of the motor shafts, the clamping mechanism 4, and the contact seat 3 coincide. The second motor 25 is started, causing the gear transmission component 24 and the gear ring 11 to mesh and move, thereby causing the slider 13 to move with the corresponding connecting plate 12. When the grinding roller 16 and the limiting roller 17 retract to the predetermined position, they stop. At this time, the gap between the two limiting rollers 17 will not cause the motor shafts to fall. The clamping mechanism 4 is started, causing the clamping mechanism 4 to expand until it expands to the predetermined range and then stops, ensuring that the clamping mechanism 4 will not obstruct the subsequent passage of the motor shafts.

[0064] Activating the multi-stage electric telescopic rod 40 causes the push plate 41 to push the motor shaft toward the contact seat 3. During this process, the motor shaft passes through the clamping mechanism 4, the limiting roller 17, and the grinding roller 16. The two limiting rollers 17 support the motor shaft. Meanwhile, since the grinding roller 16 and the limiting roller 17 retract around the center of the clamping mechanism 4 and the contact seat 3, the center of the motor shaft always coincides with the center of the clamping mechanism 4 and the contact seat 3 during the movement. When one end of the motor shaft is blocked by the contact seat 3, it stops. Then, the multi-stage electric telescopic rod 40 causes the push plate 41 to return to the initial position and stop. Next, the clamping mechanism 4 is activated so that the other end of the motor shaft is clamped and fixed by the clamping mechanism 4.

[0065] The drive mechanism 5 is activated, causing the clamping mechanism 4 to rotate with the motor shaft. The water pump 32 is activated, causing the water in the water tank 31 to be pumped into the horizontal pipe 28 and sprayed onto the surface of the motor shaft by the nozzle 30. This can cool down the subsequent grinding work of the grinding roller 16. The motor 20 is activated, and under the action of the motor 20 and the belt 22, the first wheel 18 and the second wheel 21 rotate, which in turn causes the grinding roller 16 to rotate. Since the grinding roller 16, the limiting roller 17 and the motor shaft were in contact with each other under the action of the second motor 25, the grinding roller 16 will be in contact with the surface of the motor shaft to perform the rotational grinding work. The limiting roller 17, in conjunction with the grinding roller 16, can ensure that the motor shaft will not deviate during the grinding process, which can avoid deviations in the grinding of the motor shaft surface and affect the final effect.

[0066] After the motor shaft is polished, the drive mechanism 5, motor 20, and water pump 32 are stopped. The clamping mechanism 4 engages the clamping constraint on one end of the motor shaft. Motor 25 causes the three connecting plates 12 to expand until the polishing roller 16 and the limiting roller 17 move to the predetermined position and stop. During this process, the gap between two adjacent limiting rollers 17 gradually increases, causing the motor shaft to lose the limiting constraint of the two limiting rollers 17 and fall to the buffer plate 49. The impact force generated by the falling motor shaft acts on the buffer plate 49 and compresses the spring 50, thereby buffering the impact force on the buffer plate 49. The spring 50 gradually rebounds, causing the motor shaft to roll along the buffer plate 49 to the inclined plate 51. Finally, the polished motor shaft is collected by the external collection device. The polishing of several subsequent motor shafts can be carried out in the same way.
