Description
Technical Field
[0001] This invention belongs to the technical field of motor processing equipment, and in particular relates to a processing device for high-performance motor end caps. Background Technology
[0002] The motor end cover is one of the two cover plates on the motor housing. It is usually divided into a front cover and a rear cover. It is mainly used to enclose the internal structure of the motor, protect the motor components, and provide support and fix the bearings.
[0003] After the rough machining of the motor end cover is completed and the basic shape is formed, drilling is required, and the drilled holes need to be ground. However, traditional machining equipment often has the following technical problems when grinding the motor end cover: During grinding, the grinding tool usually makes a circular motion in a specified direction, which causes the burrs in the motor end cover hole to tilt in the specified direction, reducing the grinding effect of the motor end cover; During grinding, the grinding force cannot be adjusted in real time, resulting in the grinding force remaining constant. Excessive grinding force causes hole diameter deformation or a rough surface, while insufficient grinding force results in poor grinding effect and reduced grinding precision.
[0004] Therefore, there is an urgent need for a high-performance motor end cap processing device that can prevent burrs from tilting along the grinding direction during grinding and adjust the grinding force in real time. Summary of the Invention

The outer sleeve and the inner sleeve are sealed together.
[0017] Compared with existing technologies, the advantages of this high-performance motor end cap processing device are:
[0018] This invention, by setting up a grinding component, allows two drive rods to rotate the semi-circular feed groove and the arc-shaped reset groove during grinding. This enables the first gear to selectively mesh with the semi-circular feed groove and the arc-shaped reset groove. When the first gear meshes with the semi-circular feed groove, it grinds the inner wall of the hole in the motor end cover. When the first gear meshes with the arc-shaped reset groove, it drives the rotating rod and the grinding roller on it to rotate in the opposite direction, achieving back-and-forth grinding of the inner wall of the hole in the motor end cover. This prevents the burrs on the hole from tilting in the specified direction, which would reduce the burr removal effect.
[0019] This invention, by incorporating a force adjustment component, allows hydraulic oil from the reservoir to be delivered to the fixed outer plate via the delivery chamber during grinding. The hydraulic oil then pushes the moving block within the fixed outer plate, altering the compression of the first spring. This changes the force of the grinding roller against the inner wall of the motor end cover hole, thus controlling and adjusting the grinding force. This avoids problems such as excessive grinding force leading to hole deformation or a rough surface, and insufficient grinding force resulting in poor grinding effects, thereby improving grinding accuracy.
[0020] This invention, by setting up segmented components, allows the guide wheels to make linear horizontal displacement perpendicular to the rack during grinding through the contact between different platforms on the stepped guide plate and the guide wheels. This, in turn, moves the piston block within the liquid storage cylinder. The grinding process can be divided into multiple stages based on the multiple platforms on the stepped guide plate. The grinding intensity can be adjusted for different stages, gradually decreasing the grinding intensity. This allows for the use of greater intensity to remove the main material in the initial stage of grinding, followed by a gradual reduction in intensity for fine grinding. This ensures the grinding effect on the inner wall of the motor end cover hole while also helping to ensure the hole's precision and surface finish.
[0021] This invention incorporates a cooling assembly. During grinding, the rotation of the rotating rod also drives the telescopic rod to rotate, causing the inner telescopic rod to consistently tend to move away from the rotating rod under centrifugal force. Because the arc-shaped plate is periodically pressed against the rotating rod by the abutment roller, the inner telescopic rod can reciprocate relative to the rotating rod, thereby reciprocatingly transporting the cooling liquid from the storage tank to the fixed outer rod through the infusion pipe, annular guide box, annular guide frame, and connecting pipe. Furthermore, the cooling liquid from the fixed outer rod is reciprocally sprayed out through the drain pipe and atomizing nozzle to the periphery of the grinding roller, effectively carrying away the heat generated during grinding, improving the cooling effect, and reducing thermal deformation during the grinding process.
[0022] This invention requires only one drive source, a motor, to achieve back-and-forth grinding of the motor end cover, real-time adjustment of the grinding force, and cooling of the grinding position, thereby improving energy utilization and machining accuracy of the motor end cover.

Detailed Implementation
[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0034] Example: Refer to Figures 1 to 9 A processing apparatus for high-performance motor end caps, comprising:
[0035] Processing platform 1;
[0036] Grinding assembly 2 includes a first support plate 21 fixedly connected to the upper wall of processing platform 1. A rotating rod 22 is rotatably connected through the first support plate 21. A telescopic plate 23 is fixedly connected to the rotating rod 22. A rotating seat 24 is fixedly installed at the telescopic end of the telescopic plate 23. A grinding roller 25 is rotatably connected to the rotating seat 24. A T-shaped plate 26 is fixedly connected to the upper wall of processing platform 1. Two drive rods 27 are rotatably connected above the T-shaped plate 26. A semi-circular feed groove 28 and an arc-shaped return groove 29 are fixedly connected to the two drive rods 27 respectively. A first gear 210 is fixedly connected to the rotating rod 22. The first gear 210 selectively meshes with the semi-circular feed groove 28 and the arc-shaped return groove 29.
[0037] Each of the two drive rods 27 is fixedly connected to a synchronous gear 211, which meshes with each other. The end of the T-shaped plate 26 away from the synchronous gear 211 is fixedly mounted with a first motor 3 for driving the drive rod 27. Thus, while the first motor 3 drives one of the two drive rods 27 to rotate, the synchronous gear 211 drives the other drive rod 27 to rotate, so that the two drive rods 27 always rotate synchronously in opposite directions, saving the drive source and ensuring that the first gear 210 always selectively meshes with the semi-circular feed groove 28 and the arc-shaped reset groove 29 without error.
[0038] Among them, the coverage angle of the arc-shaped reset tooth groove 29 is slightly smaller than that of the semi-circular feed tooth groove 28. This allows the semi-circular feed tooth groove 28 to drive the first gear 210 and the rotating rod 22 to rotate at a certain angle, while the arc-shaped reset tooth groove 29 drives the first gear 210 and the rotating rod 22 to rotate at a slightly smaller angle. This ensures the continuous feeding of the grinding roller 25 while grinding the inner wall of the motor end cover hole back and forth.
[0039] To address the problem in existing technologies where grinding tools typically perform circular motion in a specified direction, causing burrs inside the motor end cover hole to tilt in that direction and reducing the grinding effect on the motor end cover, this invention addresses this issue by incorporating a grinding assembly 2. During grinding, two drive rods 27 respectively rotate the semi-circular feed groove 28 and the arc-shaped return groove 29, allowing the first gear 210 to selectively mesh with both. When the first gear 210 meshes with the semi-circular feed groove 28, it drives the rotating rod 22 and the grinding roller 25 thereon to rotate clockwise. At a fixed angle, the inner wall of the hole in the motor end cover is polished. When the first gear 210 meshes with the arc-shaped reset tooth groove 29, it will drive the rotating rod 22 and the polishing roller 25 on it to rotate counterclockwise by a certain angle, so as to achieve back-and-forth polishing of the inner wall of the hole in the motor end cover, and prevent the burrs on it from tilting in the specified direction, which would reduce the burr removal effect. Since the angle of rotation of the polishing roller 25 under the action of the semi-circular feed tooth groove 28 is slightly larger than the angle of rotation under the action of the arc-shaped reset tooth groove 29, the continuous feeding of the polishing roller 25 is guaranteed, and the inner wall of the hole in the motor end cover is fully polished.
[0040] In addition, a second motor 4 for driving the grinding roller 25 is provided on the side wall of the rotating seat 24. The second motor 4 is a high-speed motor. In actual grinding, the grinding roller 25 can be driven to rotate at high speed by the second motor 4 to achieve grinding treatment of the inner wall of the motor end cover hole. At the same time, it can throw out the debris at the grinding area to avoid it getting stuck between the grinding roller and the workpiece, causing defects such as scratches during grinding.
[0041] It also includes a force adjustment component 5, which is used to adjust the grinding force during the grinding process. The force adjustment component 5 includes a liquid storage cylinder 51 fixedly installed above the processing platform 1. A liquid infusion chamber 52 is opened inside the rotating rod 22. The rotating rod 22 is sealed and rotatably connected to the side wall of the liquid storage cylinder 51, and the liquid infusion chamber 52 is connected to the inside of the liquid storage cylinder 51. The telescopic plate 23 includes a fixed outer plate 53 and a telescopic inner plate 54 slidably connected to the inner wall of the fixed outer plate 53. A moving block 55 is sealed and slidably connected inside the fixed outer plate 53. A first spring 56 is provided between the moving block 55 and the telescopic inner plate 54. The area inside the fixed outer plate 53 above the moving block 55 is connected to the liquid infusion chamber 52.
[0042] To address the problem in existing technologies where the grinding intensity cannot be adjusted in real time, resulting in a constant grinding intensity, excessive grinding intensity leading to hole deformation or a rough surface, and insufficient grinding intensity causing poor grinding effect and reduced grinding precision, this invention addresses this issue by incorporating a force adjustment component 5. During grinding, hydraulic oil from the reservoir 51 is delivered to the fixed outer plate 53 via the delivery chamber 52. The hydraulic oil compresses and pushes the moving block 55 within the fixed outer plate 53, altering the compression degree of the first spring 56. This changes the elasticity of the first spring 56, further altering the force of the grinding roller 25 on the telescopic inner plate 54 against the inner wall of the motor end cover hole. This allows for control and adjustment of the grinding intensity, enabling adjustments based on requirements. This avoids the problems of excessive grinding intensity causing hole deformation or a rough surface, and insufficient grinding intensity resulting in poor grinding effect, thus improving grinding precision.
[0043] It also includes a segmented component 6, used to divide the grinding process into multiple stages, each with a different grinding intensity. The segmented component 6 includes a second support plate 61 fixedly connected to the upper wall of the processing platform 1. A transmission rod 62 is rotatably connected through the second support plate 61. A large gear 63 is fixedly connected to the transmission rod 62, and a small gear 64 is fixedly connected to the rotating rod 22. The large gear 63 and the small gear 64 mesh with each other. A third gear 65 is fixedly connected to the end of the transmission rod 62 away from the large gear 63. A movable plate 66 is linearly slidably connected to the upper wall of the processing platform 1. Specifically, a longitudinal slide rail (not shown in the figure) can be set on the processing platform 1, and the lower end of the movable plate 66 is slidably connected to the longitudinal slide rail. A rack 67 is fixedly connected by a connecting rod, and a third gear 65 meshes with the rack 67. A stepped guide plate 68 is fixedly connected to the moving plate 66 by an extension rod. A piston block 69 is slidably connected to the inside of the liquid storage cylinder 51. A second spring 610 is provided between the piston block 69 and the inner wall of the liquid storage cylinder 51. An L-shaped rod 611 is fixedly connected to the side wall of the piston block 69. The L-shaped rod 611 extends to the outside of the liquid storage cylinder 51, and a guide wheel 612 is rotatably connected to the bottom of the L-shaped rod 611. The guide wheel 612 contacts and rolls with the stepped guide plate 68. It should be noted that there is a slope transition between two adjacent platforms of the stepped guide plate 68 to ensure that the guide wheel 612 can roll back and forth on the stepped guide plate 68.
[0044] To achieve more precise grinding of the inner wall of the motor end cover hole, this invention incorporates a segmented assembly 6. During grinding, the rotation of the rotating rod 22 drives the rotation of the large gear 63 via the pinion 64 (the cooperation between the pinion 64 and the large gear 63 achieves a speed reduction effect, ensuring sufficient grinding time for each stage and guaranteeing the grinding effect). This further drives the third gear 65 via the transmission rod 62, causing the rack 67 and the stepped guide plate 68 to undergo linear horizontal displacement. The contact between different platforms on the stepped guide plate 68 and the guide wheel 612 further enhances the grinding process. The guide wheel 612 can be driven to make a linear horizontal displacement perpendicular to the rack 67, thereby driving the piston block 69 to move inside the liquid storage cylinder 51 through the L-shaped rod 611. According to the multiple platforms on the stepped guide plate 68, the grinding process can be divided into multiple stages, and the grinding force can be adjusted for different stages, so that the grinding force gradually decreases. In the early stage of grinding, a larger force can be used to remove the main material, and then the force can be gradually reduced for fine grinding. This ensures the grinding effect on the inner wall of the motor end cover hole, while also helping to ensure the accuracy and surface smoothness of the hole.
[0045] It also includes a cooling assembly 7 to reduce thermal deformation during the grinding process. The cooling assembly 7 includes a telescopic rod 71 fixedly connected to the rotating rod 22. The telescopic rod 71 includes a fixed outer rod 72 and a telescopic inner rod 73 that is slidably connected to the inner wall of the fixed outer rod 72. An arc-shaped plate 74 is fixedly connected to the part of the telescopic inner rod 73 that extends outside the fixed outer rod 72. A roller 75 is provided above the processing platform 1. The arc-shaped plate 74 periodically abuts against the roller 75. The side wall of the fixed outer rod 72 is connected to a connecting pipe. There is an annular guide frame 76, and an annular liquid guide box 77 is fixedly connected to the upper end of the processing platform 1. The annular guide frame 76 is rotatably connected to the side wall of the annular liquid guide box 77. A liquid storage tank 78 is provided above the processing platform 1. A liquid delivery pipe 79 is connected between the inside of the liquid storage tank 78 and the inside of the annular liquid guide box 77. A drain pipe 710 is connected to the outer wall of the fixed outer rod 72 near the grinding roller 25. An atomizing nozzle is provided at the end of the drain pipe 710. A one-way valve is provided in both the liquid delivery pipe 79 and the drain pipe 710.
[0046] The one-way valve ensures that the coolant inside the fixed outer rod 72 can only be discharged through the drain pipe 710 to the atomizing nozzle. During suction, the coolant in the storage tank 78 can only be delivered to the fixed outer rod 72, ensuring continuous pumping of the coolant and preventing the backflow of the coolant from reducing the cooling effect on the grinding position.
[0047] The arrangement of the infusion pipe 79, the annular liquid guide box 77, the annular flow guide frame 76, and the connecting pipe ensures that when the rotating rod 22 rotates, the annular flow guide frame 76 rotates relative to the annular liquid guide box 77, thereby preventing the pipe conveying the cooling liquid from becoming tangled when the rotating rod 22 rotates and avoiding motion interference.
[0048] To reduce thermal deformation during the grinding process, this invention incorporates a cooling assembly 7. During grinding, the rotation of the rotating rod 22 also drives the telescopic rod 71 to rotate, causing the telescopic inner rod 73 to consistently tend to move away from the rotating rod 22 under centrifugal force. As the arc-shaped plate 74 is periodically pressed against the rotating rod 22 by the abutting roller 75, the telescopic inner rod 73 can reciprocate relative to the rotating rod 22, thereby reciprocatingly transporting the cooling liquid in the storage tank 78 through the infusion pipe 79, the annular liquid guide box 77, the annular guide frame 76, and the connecting pipe to the fixed outer rod 72. Furthermore, the cooling liquid in the fixed outer rod 72 is reciprocally sprayed out through the drain pipe 710 and the atomizing nozzle to the periphery of the grinding roller 25, effectively carrying away the heat generated during grinding, improving the cooling effect, and reducing thermal deformation during the grinding process.
[0049] In addition, a sliding plate 8 is linearly slidably connected to the upper end of the processing platform 1. Specifically, a transverse slide rail (not shown in the figure) can be set on the processing platform 1, and the lower end of the sliding plate 8 is slidably connected in the transverse slide rail. The abutment roller 75 and the liquid storage tank 78 are both fixedly installed on the upper end of the sliding plate 8. The end of the infusion pipe 79 near the annular liquid guide box 77 is connected to an outer sleeve 81. An inner sleeve 82 is connected to the side wall of the annular liquid guide box 77. The outer sleeve 81 and the inner sleeve 82 are sealed together. Before processing, the sliding plate 8 can be slid... Move away from the rotating rod 22 so that the outer sleeve 81 and the inner sleeve 82 are separated. At this time, the motor end cover can be conveyed from the end away from the motor 213 to the side of the rotating rod 22 and sleeved on the grinding roller 25. During processing, the sliding plate 8 can be slid close to the rotating rod 22 so that the outer sleeve 81 and the inner sleeve 82 are sealed. At this time, the rotation of the rotating rod 22 can cause the arc plate 74 to intermittently abut the roller 75, and the cooling liquid can be delivered to the fixed outer rod 72 to ensure the basic operation of the processing device.
[0050] In summary, this invention only requires one drive source, motor 213, to achieve back-and-forth grinding of the motor end cover, real-time adjustment of the grinding force, and cooling of the grinding position, thereby improving energy utilization and machining accuracy of the motor end cover.
[0051] The functional principle of this invention can be explained through the following operational methods:
[0052] Before grinding, slide the sliding plate 8 away from the rotating rod 22 so that the outer sleeve 81 and the inner sleeve 82 are separated. At this time, the motor end cover can be conveyed from the end away from the motor 213 to the side of the rotating rod 22 and sleeved on the grinding roller 25. The motor end cover is clamped and fixed by a separately set clamp (not shown in the figure). Then slide the sliding plate 8 close to the rotating rod 22 so that the outer sleeve 81 and the inner sleeve 82 are sealed. At this time, the rotation of the rotating rod 22 can cause the arc plate 74 to intermittently abut against the roller 75.
[0053] During grinding, the second motor 4 is turned on, driving the grinding roller 25 to rotate at high speed to grind the inner wall of the motor end cover hole. The first motor 3 is turned on, and under the action of the synchronous gear 211, it drives the two drive rods 27 to rotate synchronously. The two drive rods 27 drive the semi-circular feed groove 28 and the arc-shaped reset groove 29 to rotate respectively, so that the first gear 210 selectively meshes with the semi-circular feed groove 28 and the arc-shaped reset groove 29. When the first gear 210 meshes with the semi-circular feed groove 28, it will drive the rotating rod 22 and the grinding roller 25 on it to rotate clockwise by a certain angle to grind the inner wall of the motor end cover hole. When the first gear 210 meshes with the arc-shaped reset groove 29, it will drive the rotating rod 22 and the grinding roller 25 on it to rotate counterclockwise by a certain angle to grind the inner wall of the motor end cover hole back and forth.
[0054] The rotation of the rotating rod 22 will drive the large gear 63 to rotate via the small gear 64, and further drive the third gear 65 to rotate via the transmission rod 62. This causes the rack 67 and the stepped guide plate 68 to perform linear horizontal displacement. Through the contact between different platforms on the stepped guide plate 68 and the guide wheel 612, the guide wheel 612 can be driven to perform linear horizontal displacement perpendicular to the rack 67. This, in turn, drives the piston block 69 to move within the reservoir 51 via the L-shaped rod 611, transporting the hydraulic oil in the reservoir 51 to the fixed outer plate 53 through the infusion chamber 52. The hydraulic oil then moves the fixed outer plate 53. The squeezing and pushing of the inner moving block 55 changes the degree of compression of the first spring 56, thereby changing the elastic force of the first spring 56, and further changing the force of the grinding roller 25 on the telescopic inner plate 54 against the inner wall of the motor end cover hole. This not only realizes the control and adjustment of the grinding force, but also divides the grinding process into multiple stages according to the multiple platforms on the stepped guide plate 68. The grinding force is adjusted for different stages, so that the grinding force gradually decreases. In the early stage of grinding, a larger force is used to remove larger protruding materials on the hole wall, and then the force is gradually reduced for fine grinding.
[0055] The rotation of the rotating rod 22 will also drive the telescopic rod 71 to rotate, so that the telescopic inner rod 73 always tends to move away from the rotating rod 22 under the action of centrifugal force. As the arc plate 74 is periodically pushed close to the rotating rod 22 by the abutting roller 75, the telescopic inner rod 73 can reciprocate relative to the rotating rod 22, thereby reciprocatingly spraying the cooling liquid in the fixed outer rod 72 through the drain pipe 710 and the atomizing nozzle to the periphery of the grinding roller 25, effectively carrying away the heat generated during grinding and reducing thermal changes during the grinding process.
[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
