Description

Technical Field

[0001] The invention relates to the technical field of end cover grinding, and in particular to a motor end cover processing and grinding device. Background Art

[0002] Motor end covers, also known as motor end cover plates, are a crucial component of the motor housing. Located at each end of the motor, they secure and seal key components such as the rotor, stator, and bearings. These covers are typically made of materials such as cast iron and aluminum alloy, offering excellent mechanical strength and insulation properties.

[0003] During the production process of servo motor end covers, polishing work mainly targets the following areas: First, the outer surface of the end cover is polished to remove burrs, unevenness, and oxide layers from the casting process, ensuring a smooth and beautiful surface. Secondly, the internal grooves, holes, and chamfers of the end cover are polished to eliminate casting defects and ensure the accuracy of the internal structure and the tightness of the assembly. Finally, the edges of the end cover are polished to ensure there are no sharp edges and smooth threads to facilitate subsequent assembly and disassembly operations. Through these polishing processes, the overall quality and service life of the motor end cover can be improved.

[0004] For example, the patent document with the authorization announcement number CN211053449U, named as a hydraulic chuck tool for grinding motor end cover, when preparing to process the end cover, it is necessary to fix the connecting flange on the main shaft of the lathe, fix the hydraulic rod on the lathe, place the guide body in the step through hole of the connecting flange and fix it together with the hydraulic rod, fix the positioning seat on the connecting flange, assemble the pull rod and the pressure block, screw the pull rod through the through hole of the positioning seat and the threaded hole of the guide body, rotate the pressure block 90°, and then the hydraulic rod pulls the guide body toward the lathe, and the end cover is tightly fixed on the positioning seat for processing; after processing, the hydraulic rod pushes the guide body forward, and the long side of the pressure block is placed in the same line with the pull rod, and the end cover can be removed.

[0005] Regarding the aforementioned related technologies, since both ends of the end cap need to be machined, the operator needs to rotate the end cap 180 degrees after removing it and then fix it on the grinder for grinding. In addition, when grinding the internal groove of the end cap, since the inner side of the groove has a chamfer, the operator needs to replace the corresponding grinding head to adjust the inclined chamfer. This makes the operator's operation more complicated when grinding the end cap, which has a negative impact on the end cap processing efficiency. Summary of the Invention

[0006] In view of this, the present invention provides a motor end cover processing and grinding device, which aims to solve the problem that when grinding the end cover, the operator's operation is relatively complicated, which has a negative impact on the processing efficiency of the end cover.

[0007] In order to solve the above technical problems, the present invention provides a motor end cover processing and grinding device, comprising a grinder body, a chuck for driving the end cover to rotate, and a grinding wheel for grinding the terminal; a universal joint is hinged between the grinder body and the chuck, and a linear drive 1 for adjusting the angle of the chuck is hinged between the grinder body and the chuck; the grinder body is fixedly connected to a linear drive 2, a driving shaft of the linear drive 2 is fixedly connected to a connecting frame, a linear drive 3 is provided on the connecting frame, and the driving shaft of the linear drive 3 is fixedly connected to a bracket, and the bracket is provided between the chuck and the grinding wheel, the outer side surface of the bracket is fixedly connected to a rotation source 1, the driving shaft of the rotation source 1 is fixedly connected to a flip frame, the inner side surface of the flip frame is connected to a rotating frame, and the rotating frame is connected to a clamping member for clamping the end cover.

[0008] By adopting the above technical solution, the clamping part continuously fixes the end cover, the linear drive 1 adjusts the angle of the chuck, and the rotation source 1 adjusts the angle of the end cover. When one side of the end cover is polished and needs to be flipped, the linear drive 1 first drives the chuck to rotate 45°, and the rotation source 1 drives the end cover to rotate 45°, so that the grinding wheel polishes the chamfer of the end cover. After the end cover is polished, the rotation source 1 flips the end cover so that the other side of the end cover is polished, thereby completing the chamfer polishing and double-sided polishing of the end cover, reducing the operator's manual flipping of the end cover and improving the grinding efficiency of the end cover.

[0009] Optionally, the bracket is provided with a liquid inlet groove for circulating the coolant, and the bracket is provided with a circulation groove and a liquid outlet groove. The two ends of the circulation groove are respectively connected to the liquid inlet groove and the liquid outlet groove, and the liquid outlet groove is used to transport the coolant to the terminal surface.

[0010] By adopting the above technical solution, when the grinding wheel is grinding the end cover, the coolant is transported to the surface of the end cover through the liquid inlet groove, the circulation groove and the liquid outlet groove in sequence, so as to cool the grinding of the end cover.

[0011] Optionally, the flip frame is hinged to the bracket through a connecting tube, the connecting tube is connected to the liquid inlet tank, the rotating frame is provided with an infusion tank connected to the connecting tube, the clamping member is slidingly connected to the infusion tank, and the clamping member is provided with a reset spring for driving the clamping member to separate from the end cover.

[0013] By adopting the above technical solution, after the end cap is ground, the second rotating source drives the two C-shaped frames to rotate 180° around the connecting plate, and the two C-shaped frames rotate and change positions. The end cap and the C-shaped frame rotate and change positions around the connecting plate synchronously, so that when the end cap on one rotating frame is ground, the other rotating frame is located outside the grinder body to facilitate the processing personnel to load and unload the end cap, further improving the processing efficiency of the end cap.

[0014] Optionally, the driving shaft fixing sleeve of the rotation source 2 is provided with a driving gear, the side wall of the connecting frame is rotatably connected to a transmission gear that can engage with the driving gear, the linear drive 3 is fixedly connected to the transmission gear, and the linear drive 3 is fixedly connected to the connecting plate through a transmission shaft.

[0016] By adopting this technical solution, the C-shaped frame rotates around the connecting plate, allowing the grinding and replacement of the end caps on both sides of the connecting plate to proceed synchronously while controlling the flow of coolant. In the end caps not being processed, the coolant pushes the clamps to fix the end caps, and does not flow to the end cap surface to cause waste.

[0017] Optionally, a counterweight is fixedly connected to the outer side surface of the rotating frame.

[0018] By adopting the above technical solution, when the chuck does not fix the end cover, the counterweight block drives the rotating frame to rotate to the initial position due to its own gravity, that is, the counterweight block is located at the lower end of the rotating frame. At this time, the two positioning rods are in a horizontal state, which is conducive to the chuck fixing the end cover in the vertical direction.

[0019] Optionally, the clamping member is composed of a sliding rod and a V-shaped block, the sliding rod is slidably connected to the rotating frame, and the V-shaped block abuts against the end cover.

[0020] Optionally, the grinding machine body is provided with a driving mechanism for driving the grinding wheel to move.

[0021] Optionally, the driving mechanism includes a rotation source 2 fixedly connected to the outer side of the grinder body, the rotation source 2 is fixedly connected to a transmission screw 1, the transmission screw 1 is threadedly connected to a sliding frame, the sliding frame is slidably connected to the grinder body, the upper surface of the sliding frame is fixedly connected to a rotation source 3, the rotation source 3 is fixedly connected to a transmission screw 2 perpendicular to the transmission screw 1, the transmission screw 2 is threadedly connected to the rotation source 3, the rotation source 3 is slidably connected to the sliding frame, and the grinding wheel is fixedly connected to the rotation source 3.

The clamping part continuously fixes the end cap, the linear drive adjusts the angle of the chuck, and the rotation source adjusts the angle of the end cap. When one side of the end cap is polished and needs to be flipped, the linear drive first drives the chuck to rotate 45°, and the rotation source drives the end cap to rotate 45°, so that the grinding wheel grinds the chamfer of the end cap. After the end cap is polished, the rotation source flips the end cap so that the other side of the end cap is polished, thereby completing the chamfer grinding and double-sided grinding of the end cap, reducing the operator's manual flipping of the end cap and improving the grinding efficiency of the end cap.

[0023] 2. The C-shaped frame rotates around the connecting plate, allowing the grinding and replacement of the end caps on the left and right sides of the connecting plate to proceed synchronously while controlling the flow of coolant. In the end caps not being processed, the coolant pushes the clamps to fix the end caps and is not delivered to the end cap surface, causing waste. In the end caps being processed, the coolant continues to push the clamps to fix the end caps and is simultaneously delivered to the end cap surface to cool the parts.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figures 1-6 , clearly and completely describe the technical solutions of the embodiments of the present invention.

[0027] This embodiment provides a motor end cover processing and grinding device, referring to Figure 1 、 Figure 2 and Figure 3 A motor end cover processing and grinding device includes a grinder body 1, a chuck 11 for driving the end cover 2 to rotate, a grinding wheel 3 for grinding the terminal, a bracket 4, and a flip frame 42 for driving the stator to flip. The grinder body 1 is erected on a horizontal plane, and the chuck 11 is arranged on the grinder body 1. Specifically, the chuck 11 is a two-jaw chuck 11, and the grinder body 1 can drive the chuck 11 to rotate. A universal joint 12 is hinged between the grinder body 1 and the chuck 11. Four linear drives 13 for adjusting the angle of the chuck 11 are hinged between the grinder body 1 and the chuck 11, and the four linear drives 13 are evenly distributed on the upper and lower sides of the chuck 11.

[0028] Reference Figure 1 、 Figure 2 and Figure 4The grinding machine body 1 is vertically fixedly connected to a linear actuator 2 14. The drive shaft of the linear actuator 2 14 is fixedly connected to a connecting frame 15. A linear actuator 3 16 is mounted on the connecting frame 15 and is in a horizontal position. A bracket 4 is fixedly connected to the drive shaft of the linear actuator 3 16. The bracket 4 is disposed between the chuck 11 and the grinding wheel 3. The arc-shaped outer side of the bracket 4 is fixedly connected to a rotation source 1 41. The drive shaft of the rotation source 1 41 is fixedly connected to a flip frame 42. The inner side of the flip frame 42 is rotatably connected to a rotating frame 43. The rotating frame 43 can rotate along the circumference of the flip frame 42. The rotating frame 43 is connected to two clamping members 44 for clamping the end cap 2. The two clamping members 44 are located at both ends of the rotating frame 43, and the central axes of the two clamping members 44 coincide. The clamping members 44 are composed of a slide rod 442 and a V-shaped block 443. The slide rod 442 is slidably connected to the rotating frame 43, and the two V-shaped blocks 443 cooperate to clamp the end cap 2.

[0029] First, the operator places the end cap 2 to be ground between two clamps 44. Clamps 44 clamp the ends of the end cap 2, securing it. Linear actuator 13 rotates the chuck 11 to a vertical position. Linear actuator 2 14 adjusts the vertical height of the bracket 4 via the connecting frame 15. Linear actuator 3 16 drives the bracket 4 toward the chuck 11. The end cap 2 moves synchronously with the bracket 4, abutting against the outer surface of the chuck 11. The sliding claws of the chuck 11 start to clamp the end cap 2. The grinding machine body 1 drives the end cap 2 to rotate via the chuck 11. The grinding wheel 3 starts to grind the side of the end cap 2. At this time, the rotating frame 43 rotates synchronously with the end cap 2.

[0030] Reference Figure 3 When the grinding wheel 3 has finished grinding one side of the end cap 2, it detaches from the end cap 2. The linear actuator 13 located above contracts, while the linear actuator 13 located below extends, driving the chuck 11 to rotate 45° counterclockwise. The rotation source 1 41 adapts to the chuck 11 and drives the flip frame 42 to rotate 45° counterclockwise. The flip frame 42 drives the end cap 2 to rotate 45° through the rotating frame 43, causing the bottom end of the 45° chamfer of the end cap 2 to rotate to a horizontal state. At the same time, the linear actuator 2 14 and the linear actuator 3 16 adapt to the chuck 11 and drive the end cap 2 to move. The grinding wheel 3 moves to the bottom end of the chamfer and fits the chamfer. The grinding machine body 1 drives the end cap 2 to rotate through the chuck 11, causing the grinding wheel 3 to grind the chamfer.

[0031] After the chamfering is completed, the grinding wheel 3 is separated from the end cap 2, the chuck 11 is loosened from the end cap 2, and the linear drive 3 16 drives the end cap 2 to separate from the chuck 11 through the bracket 4. The two linear drives 13 drive the chuck 11 to rotate clockwise to a vertical state, and the rotation source 1 41 drives the end cap 2 to rotate counterclockwise 135 degrees through the flip frame 42 and the rotating frame 43 (refer to Figure 3), thereby turning over the end cap 2. The second linear actuator 14 and the third linear actuator 16 drive the end cap 2 to move to the chuck 11. The grinding machine body 1 again drives the end cap 2 to rotate through the chuck 11, so that the grinding wheel 3 grinds the back side of the end cap 2.

[0032] The clamping member 44 continuously fixes the end cover 2, the linear drive 13 adjusts the angle of the chuck 11, and the rotating source 41 adjusts the angle of the end cover 2. When one side of the end cover 2 is polished and needs to be flipped, the linear drive 13 first drives the chuck 11 to rotate 45°, and the rotating source 41 drives the end cover 2 to rotate 45°, so that the grinding wheel 3 grinds the chamfer of the end cover 2. After the end cover 2 is polished, the rotating source 41 flips the end cover 2 so that the other side of the end cover 2 is polished, thereby completing the chamfer grinding and double-sided grinding of the end cover 2, reducing the operator's manual flipping of the end cover 2 and improving the grinding efficiency of the end cover 2.

[0033] Reference Figure 4 and Figure 5 The bracket 4 is provided with a liquid inlet groove 45 for circulating the coolant. The liquid inlet groove 45 can be connected to an external liquid infusion pipe for conveying the coolant. The bracket 4 is provided with a flow groove 46 and a liquid outlet groove 47. The flow groove 46 is arranged between the liquid inlet groove 45 and the liquid outlet groove 47, and the two ends of the flow groove 46 are respectively connected to the liquid inlet groove 45 and the liquid outlet groove 47. The liquid outlet groove 47 is provided on the inner side surface of the bracket 4. When the grinding wheel 3 is grinding the end cap 2, the coolant is sequentially conveyed to the surface of the end cap 2 through the liquid inlet groove 45, the flow groove 46, and the liquid outlet groove 47, thereby cooling the end cap 2 during grinding.

[0034] Reference Figure 4 and Figure 5 The tilt frame 42 is hingedly connected to the bracket 4 via a connecting tube 421. The connecting tube 421 is connected to the liquid inlet trough 45. The rotating frame 43 is provided with an infusion trough 431 connected to the connecting tube 421. The infusion trough 431 extends along the circumference of the rotating frame 43. The clamping member 44 is slidably connected to the infusion trough 431. The clamping member 44 is provided with a return spring 441 for driving the clamping member 44 away from the end cover 2. The return spring 441 is fixedly connected between the clamping member 44 and the inner side of the rotating frame 43. When the coolant in the liquid inlet trough 45 enters the infusion trough 431 through the connecting tube 421, the coolant pushes the clamping member 44 toward the central axis of the rotating frame 43. In other words, the coolant pushes the two clamping members 44 toward each other to clamp the end cover 2, and the return spring 441 is stretched. When the end cover 2 is polished, the processing personnel extract the coolant in the liquid inlet tank 45, and the stretched return spring 441 pulls the clamping member 44 out of the end cover 2 so that the end cover 2 can be unloaded.

[0035] Reference Figure 4 and Figure 5The bracket 4 consists of two C-shaped frames 48 and a connecting plate 49. The connecting plate 49 is fixedly connected between the two C-shaped frames 48. Two flip frames 42, two rotating frames 43, and two rotating sources 41 are each provided. Each flip frame 42, rotating frame 43, and rotating source 1 41 corresponds to a C-shaped frame 48. The flip frame 42 is rotatably connected to the C-shaped frame 48. The liquid inlet groove 45 is provided on the connecting plate 49. The flow groove 46 and the liquid outlet groove 47 are provided on the C-shaped frame 48. The flow groove 46 extends along the circumference of the C-shaped frame 48. Multiple liquid outlet grooves 47 are provided along the circumference of the C-shaped frame 48, and each liquid outlet groove 47 is provided along the radial direction of the C-shaped frame 48. The connecting frame 15 is fixedly connected to the rotating source 151. The drive shaft of the rotating source 151 is fixedly connected to the connecting plate 49. The rotating source 151 is used to drive the C-shaped frame 48 to rotate about the connecting plate 49.

[0036] After the end cover 2 is ground, the second rotation source 151 drives the two C-shaped frames 48 to rotate 180° around the connecting plate 49. The two C-shaped frames 48 rotate and change positions, and the end cover 2 and the C-shaped frames 48 rotate and change positions around the connecting plate 49 synchronously, so that when the end cover 2 on one rotating frame 43 is ground, the other rotating frame 43 is located outside the grinding machine body 1 so that the processing personnel can load and unload the end cover 2, further improving the processing efficiency of the end cover 2.

[0037] Reference Figure 2 The drive shaft of the second rotation source 151 is fixedly sleeved with a drive gear 152, which is rotatably connected to the connecting frame 15. A transmission gear 153, which meshes with the drive gear 152, is rotatably connected to the side wall of the connecting frame 15. The third linear actuator 16 is fixedly connected to the outer side of the transmission gear 153. The drive shaft of the third linear actuator 16 is fixedly connected to a transmission shaft 161, which passes through the transmission gear 153 and is fixedly connected to the transmission gear 153. The transmission shaft 161 is rotatably connected to the connecting frame 15 and can slide along the connecting frame 15. The end of the transmission shaft 161 away from the connecting frame 15 is fixedly connected to the connecting plate 49. The third rotation source 61 drives the connecting plate 49 to rotate via the drive gear 152, the transmission gear 153, and the transmission shaft 161, causing the two C-shaped frames 48 to rotate about the connecting plate 49.

[0038] Reference Figure 2 and Figure 6The control cam 5 is rotatably connected to the outer side of the connecting plate 49. A connecting rod 51 is fixedly connected between the control cam 5 and the connecting frame 15. The connecting plate 49 is horizontally slidably connected to two closing blocks 52, which are located on either side of the control cam 5. A return spring 53 is fixedly connected between the control cam 5 and the closing blocks 52. Because the connecting rod 51 is fixedly connected between the control cam 5 and the connecting frame 15, the control cam 5 remains stationary relative to the connecting frame 15. The end cap 2 located to the left of the control cam 5 is being ground, while the end cap 2 located to the right of the control cam 5 remains unmachined outside the grinding machine.

[0039] On the right side of the control cam 5, the far resting position of the control cam 5 can push the closing block 52 to the right to close the flow slot 46. At this time, the C-shaped frame 48 is located outside the grinding machine body 1. The coolant in the liquid inlet trough 45 is delivered to the surface of the end cap 2 without passing through the flow slot 46 and the liquid outlet trough 47. At this time, the return spring 2 53 is stretched. On the left side of the control cam 5, the return spring 2 53 pulls the closing block 52 to the left to disengage the flow slot 46. At this time, the coolant in the liquid inlet trough 45 is delivered to the surface of the end cap 2 being processed through the flow slot 46 and the liquid outlet trough 47.

[0040] Thus, the C-shaped frame 48 rotates around the connecting plate 49, allowing the grinding and replacement of the end caps 2 on the left and right sides of the connecting plate 49 to proceed synchronously while controlling the flow of the coolant. At the end caps 2 not being processed, the coolant pushes the clamps 44 to secure the end caps 2, and is not delivered to the surface of the end caps 2, causing waste. At the end caps 2 being processed, the coolant continues to push the clamps 44 to secure the end caps 2, while the coolant is delivered to the surface of the end caps 2 to cool the parts.

[0041] Reference Figure 1 A counterweight 432 is fixedly connected to the outer side of the rotating frame 43 and is located between the two clamping members 44. When the chuck 11 is not fixed to the end cap 2, the counterweight 432 drives the rotating frame 43 to rotate to its initial position due to its own gravity. That is, the counterweight 432 is located at the lower end of the rotating frame 43. At this time, the two clamping members 44 are in a horizontal state, which helps the chuck 11 to fix the end cap 2 in the vertical direction.

[0042] Reference Figure 1The grinding machine body 1 is provided with a driving mechanism 6 for driving the grinding wheel 3 to move. The driving mechanism 6 includes a rotation source 3 61, a transmission screw 1 62, a sliding frame 63, a rotation source 4 64, a transmission screw 2 65, and a rotation source 5 66. The rotation source 3 61 is fixedly connected to the outer side surface of the grinding machine body 1, the transmission screw 1 62 is fixedly connected to the drive shaft of the rotation source 2 151, the sliding frame 63 is threadedly connected to the transmission screw 1 62, and the sliding frame 63 is horizontally slidably connected to the grinding machine body 1. The rotation source 4 64 is fixedly connected to the upper surface of the sliding frame 63, the transmission screw 2 65 is fixedly connected to the drive shaft of the rotation source 4 64, and the transmission screw 1 62 and the transmission screw 2 65 are perpendicular to each other. The rotation source 5 66 is threadedly connected to the transmission screw 2 65, and the rotation source 5 66 is slidably connected to the sliding frame 63. The grinding wheel 3 is fixedly connected to the rotation source 5 66, and the rotation source 5 66 drives the grinding wheel 3 to rotate to grind the end cap 2.

[0043] Rotation source 3 61, drive screw 1 62, and slide 63 form a screw-slider structure. Rotation source 3 61 drives slide 63 horizontally and reciprocally via drive screw 1 62. Rotation source 4 64, drive screw 2 65, and rotation source 5 66 form another screw-slider structure. Rotation source 4 64 drives drive screw 5 66 horizontally and reciprocally via drive screw 2 65, with the direction of rotation source 5 66 moving perpendicular to that of slide 63. The grinding wheel 3 moves synchronously with rotation source 5 66, thereby adjusting the relative position between the grinding wheel 3 and end cap 2.

[0044] The operating principle of a motor end cap processing and grinding device according to an embodiment of the present invention is as follows: a clamping member 44 clamps both ends of the end cap 2, thereby securing the end cap 2. The sliding claws of the chuck 11 start to clamp the end cap 2. The grinding machine body 1 drives the end cap 2 to rotate via the chuck 11, and the grinding wheel 3 starts to grind the side of the end cap 2. When the grinding wheel 3 has finished grinding one side of the end cap 2, the upper linear actuator 13 contracts, while the lower linear actuator 13 extends, driving the chuck 11 to rotate 45°. The rotation source 1 41 adapts to the chuck 11, driving the end cap 2 to rotate 45° via the tilting frame 42. Simultaneously, the linear actuator 2 14 and the linear actuator 3 16 adapt to the chuck 11 to drive the end cap 2 to move. The grinding wheel 3 moves to the lowest end of the chamfer and aligns with the chamfer. The grinding machine body 1 drives the end cap 2 to rotate via the chuck 11, causing the grinding wheel 3 to grind the chamfer.

[0045] After chamfering is complete, the grinding wheel 3 disengages the end cap 2, the chuck 11 releases the end cap 2, and the linear actuator 3 16 drives the end cap 2 off the chuck 11 via the bracket 4. The two linear actuators 13 rotate the chuck 11 to a vertical position. The rotation source 1 41 rotates the end cap 2 135° via the tilting frame 42 and the rotating frame 43, thereby turning the end cap 2 over. The linear actuators 2 14 and 3 16 move the end cap 2 to the chuck 11. The grinding machine body 1 again drives the end cap 2 to rotate via the chuck 11, causing the grinding wheel 3 to grind the back surface of the end cap 2.

[0046] In addition, it should be noted that in the description of the present invention, the terms "install", "connect" and "connect" should be understood in a broad sense.

[0047] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
