Abstract

The application discloses a motor shell outer surface finishing mechanism which is used for polishing motor shell raw materials and comprises a first sliding frame, a second sliding frame and a polishing mechanism. The first sliding frame is used for mounting and rotating the motor shell raw materials. Since the motor shell raw materials are in a shape of seven equal parts and have seven planes, the first sliding frame rotates the motor shell raw materials so that the seven planes are all directed to the polishing mechanism for polishing. The second sliding frame is arranged on the same plane as the first sliding frame. The polishing mechanism is arranged on the second sliding frame and can move on the second sliding frame, and is used for polishing the surface of the motor shell raw materials. The polishing mechanism moves on the second sliding frame and is suitable for matching the length of the motor shell raw materials. The motor shell raw materials are uncut raw materials for producing motor shells. If the motor shell raw materials are to be polished comprehensively, the polishing mechanism needs to move in the direction parallel to the motor shell raw materials to polish the motor shell raw materials.

Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically to a precision machining mechanism for the outer surface of a motor housing. Background Technology

[0002] For cast workpieces like motor housings with cylindrical outer walls, surface grinding is a crucial step in the finishing process to ensure subsequent assembly accuracy and coating quality. Currently, existing technologies for grinding the outer surface of motor housings commonly employ handheld electric grinding tools with fixed fixtures for manual operation, or use general-purpose cylindrical grinding machines. However, these traditional processing methods have significant limitations: Since motor housing raw materials are typically uncutable, integral cast cylindrical structures before finishing, with considerable length and weight, using handheld grinding machines is not only labor-intensive and inefficient, but also makes it difficult to maintain constant grinding pressure, easily leading to uneven grinding, localized overheating, or scratches on the outer surface. Furthermore, while general-purpose cylindrical grinding machines can achieve a certain degree of automation, their grinding wheel feed mechanisms are complex, equipment costs are high, and the clamping process is cumbersome. They are unable to adapt to subtle differences in diameter and length between different batches of motor housing raw materials, and especially cannot meet the process requirements for continuous, one-time, comprehensive grinding of the outer wall of uncutable raw materials.

[0003] Furthermore, many existing automated grinding retrofit solutions employ a method of fixing the grinding head and moving the workpiece to achieve the grinding trajectory. However, when dealing with heavy, uncut motor housing materials, this approach requires significant power and a robust support structure to drive the workpiece's rotation and axial movement, resulting in large equipment footprint and high energy consumption. Moreover, existing devices generally lack a linkage mechanism that enables stable contact between the grinding tool and the surface to be processed, simultaneously achieving axial feed. This leads to an uneven path for the grinding head on the workpiece surface, easily creating step-like marks at joints. More critically, existing technologies fail to effectively address the issues of rapid positioning of the grinding position and precise control of the grinding depth during the grinding process. Mechanical vibration or clamping misalignment often causes abrupt changes in the interaction force between the grinding wheel and the workpiece's outer wall, ultimately affecting the cylindricity and surface roughness of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a precision machining mechanism for the outer surface of an electric motor housing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision machining mechanism for the outer surface of a motor housing, used for grinding the raw material of the motor housing, comprising: The first slide is used to mount the motor housing material and drive the motor housing material to rotate.

All the support blocks are located at both ends of the base, and a limiting rod is provided on the opposite side of each set of support blocks.

[0007] In some embodiments, a drive motor is connected to the support frame, the output end of the drive motor passes through the support frame, and a limit plate is provided on the output end of the drive motor located at the other end of the support frame. A plug-in rod is provided on the limit plate, and the plug-in rod is used to insert the motor housing material.

[0008] In some embodiments, the first carriage is further provided with an adjustment mechanism, the adjustment mechanism including a fixed seat provided on the support block, a second cylinder provided on the fixed seat, a push rod provided on the output end of the second cylinder, and the push rod being connected to the support frame.

[0011] In some embodiments, the driven mechanism includes a support frame disposed on the support block, a roller provided on the side of the support frame near the motor housing material, a driven wheel provided at one end of the roller, and the driven wheel being connected to the plug rod.

The first slide is used to mount the motor housing raw material and drive its rotation. Since the motor housing raw material is divided into seven equal parts, with seven planes, the first slide must drive the motor housing raw material to rotate so that all seven planes face the grinding mechanism for grinding. The second slide and the first slide are located on the same plane and parallel to one side of the first slide. The grinding mechanism is located on the second slide and can move on the second slide. The grinding mechanism is used to grind the surface of the motor housing raw material.

The motor housing raw material is the uncut raw material used to produce the motor housing, and it is relatively long. To perform comprehensive grinding of the motor housing raw material, the grinding mechanism needs to move in a direction parallel to the motor housing raw material to grind it. Furthermore, the grinding mechanism is not always in close contact with the motor housing material. To prevent defects in the motor housing material from obstructing the grinding mechanism, the grinding wheel included in the grinding mechanism will retract, thereby avoiding damage to the grinding wheel.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8This invention provides a technical solution: a precision machining mechanism for the outer surface of a motor housing, used for grinding the motor housing material 2, comprising: a first slide 1, a second slide 3, and a grinding mechanism 4. The first slide 1 is used to mount the motor housing material 2 and drive its rotation. Since the motor housing material 2 is divided into seven equal parts, having seven planes, the first slide 1 must drive the motor housing material 2 to rotate so that all seven planes face the grinding mechanism 4, allowing the grinding mechanism 4 to perform grinding. The second slide 3 is located on the same plane as the first slide 1 and is parallel to one side of the first slide 1. The grinding mechanism 4 is located on the second slide 3 and can move on the second slide 3. The grinding mechanism 4 is used to grind the surface of the motor housing material 2. The movement of the grinding mechanism 4 on the second slide 3 is suitable for matching the length of the motor housing material 2. The motor housing material 2 is the uncut raw material used to produce the motor housing, and is relatively long. To perform comprehensive grinding of the motor housing material 2, the grinding mechanism 4 needs to move in a direction parallel to the motor housing material 2 to grind it. Furthermore, the grinding mechanism 4 is not always in close contact with the motor housing material 2. To prevent defects in the motor housing material 2 from obstructing the grinding mechanism 4, the grinding wheel 46 included in the grinding mechanism 4 will retract to avoid damage to the grinding wheel 46.

[0020] First, the first carriage 1 positions and installs the uncut cylindrical motor housing material 2, and drives the material to perform step-by-step indexing rotation around its own axis, so that the seven surfaces to be processed on its outer wall are sequentially and precisely aligned with the working direction of the grinding mechanism 4. During the grinding cycle of each surface, the second carriage 3 guides the grinding mechanism 4 to feed at a uniform speed in a straight line along a direction parallel to the axis of the motor housing material 2, thereby achieving continuous coverage grinding of the entire outer wall of the material. In particular, the grinding wheel 46 included in the grinding mechanism 4 detects the contact pressure with the workpiece surface in real time during the feeding process. When encountering local defects such as casting protrusions, hard spots, or deformation on the surface of the material, the grinding wheel 46 can actively and elastically retract away from the axis to buffer overload impact and avoid damage to the grinding tool from rigid collisions; after passing the defect area, the grinding wheel 46 automatically returns to the preset grinding depth, resuming stable grinding of the subsequent normal surface. Through the coordinated operation of the rotation indexing and axial feed, and combined with the passive adaptive yielding mechanism of the grinding wheel 46, this mechanism can efficiently complete the fine grinding of all outer surfaces of the long, uncut motor housing material 2 without manual intervention, effectively ensuring the consistency of the processed surface, while significantly reducing the equipment failure rate and scrap rate caused by defects in the raw material itself.

[0021] The first carriage 1 includes a base 11, on which two sets of support blocks 12 are provided. All support blocks 12 are located at both ends of the base 11, and a limiting rod 13 is provided on the opposite side of each set of support blocks 12. A support frame 14 is sleeved in the limiting rod 13 and can move on the limiting rod 13. With this design, when installing the motor housing material 2 in the first carriage 1, the support frame 14 can be moved away from the motor housing material 2 until the motor housing material 2 and the support frame 14 are on the same plane, and then the support frame 14 can be pushed towards the motor housing material 2 to complete the assembly of the first carriage 1 and the motor housing material 2.

[0022] A drive motor 15 is connected to the support frame 14. The output end of the drive motor 15 passes through the support frame 14, and a limit plate 16 is provided on the output end of the drive motor 15 at the other end of the support frame 14. A plug-in rod 17 is provided on the limit plate 16. The plug-in rod 17 is used to insert into the motor housing material 2. The plug-in rod 17 is inserted into the motor housing material 2 and fixes the motor housing material 2. The drive motor 15 is used to drive the plug-in rod 17 to rotate the motor housing material 2. The rotation angle matches the seven equal divisions of the motor housing material 2, so that each plane faces the grinding mechanism 4 in sequence.

[0023] The first slide 1 is also equipped with an adjustment mechanism 7. The adjustment mechanism 7 includes a fixed seat 71 on the support block 12, a second cylinder 72 on the fixed seat 71, and a push rod 73 on the output end of the second cylinder 72. The push rod 73 is connected to the support frame 14. The adjustment mechanism 7 is used to adjust the position of the support frame 14 on the base 11 to facilitate the installation of the first slide 1 and the motor housing material 2.

[0024] By first retracting the support frame 14 from the processing position, the motor housing material 2 can be directly placed between the two sets of support blocks 12 on the base 11. Then, the support frame 14 is pushed back, allowing the insertion rod 17 to be accurately inserted into the end of the motor housing material 2 for fixation. During this process, the second cylinder 72 in the adjusting mechanism 7 provides driving force to switch the position of the support frame 14 on the base 11, thus effectively avoiding the cumbersome operation of hoisting and aligning large materials in traditional clamping methods. During processing, the drive motor 15 drives the fixed motor housing material 2 to rotate precisely at indexing intervals. Each rotation angle matches the seven equally divided planes of the outer wall of the material, ensuring that the seven planes to be processed face the grinding position sequentially and accurately. This, combined with the feeding movement of the grinding mechanism 4 along the axial direction of the material, achieves full-coverage grinding of the outer wall. In particular, the adjustment mechanism 7 is not only used to assist in coarse positioning during clamping, but also to fine-tune the support frame 14 in the processing gap according to the actual length of the raw material or the deviation of the installation position, so as to compensate for the axial position change caused by the casting error of the raw material or the clamping offset, thereby ensuring that the feed stroke of the grinding mechanism 4 always corresponds precisely with the effective grinding area of ​​the outer wall of the raw material, further improving the clamping adaptability and processing benchmark consistency of multiple batches and multiple specifications of uncut motor housing raw materials 2 in the finishing process.

[0025] The first carriage 1 is also equipped with a support mechanism 5 and a driven mechanism 6. The support mechanism 5 is used to support the motor housing material 2, ensuring the stability of the motor housing material 2 during grinding. The driven mechanism 6 is used to stabilize the rotation of the motor housing material 2 by the first carriage 1.

[0026] The support mechanism 5 includes a slider 51 mounted on the base 11, which is located on the support block 12. The slider 51 has a hollow cavity 52, within which a first cylinder 53 is installed. An extension rod 54 is mounted on the output end of the first cylinder 53, and a support seat 55 is mounted on the end of the extension rod 54. The support seat 55 supports the motor housing material 2. Before the motor housing material 2 needs to rotate, the first cylinder 53 retracts the extension rod 54, causing the support seat 55 to move away from the motor housing material 2, thus relinquishing its support and allowing the motor housing material 2 to rotate, preventing any conflict between the rotation of the motor housing material 2 and the support seat 55. After the motor housing material 2 has rotated completely, the first cylinder 53 drives the extension rod 54 to push the support seat 55 into contact with the motor housing material 2. The support base 55 continues to support the motor housing material 2. The support base 55 suppresses the shaking of the motor housing material 2 when it is being polished, ensuring the stability of the motor housing material 2 and thus improving the polishing quality.

[0027] The support mechanism 5 actively adjusts the support state of the motor housing material 2 through its internal power element, achieving alternating control of support and avoidance. Whenever the motor housing material 2 needs to perform indexing rotation to switch the plane to be processed, the telescopic element in the support mechanism 5 acts first, removing the support seat 55 from the contact position with the outer wall of the material, ensuring that the material will not interfere with the movement or rub against the support components during rotation; after rotation to the correct position and the next plane is accurately aligned with the grinding station, the support seat 55 re-extends and fits against the outer wall of the material, restoring stable auxiliary support. With the active intervention of the support seat 55 in the grinding process, additional rigid support points can be provided in the middle of the material or in the large span of the suspended area, based on the insertion and fixation of both ends of the material. This effectively suppresses the radial runout and processing chatter generated by the long, uncut motor housing material 2 under grinding force, thereby significantly improving the dynamic stiffness of the workpiece during grinding, ensuring the dimensional accuracy and surface consistency of each plane after processing, and avoiding physical interference caused by the fixed support structure to the indexing rotation action, thus balancing the flexibility and stability of processing.

[0028] The driven mechanism 6 includes a support frame 61 mounted on the support block 12. A roller 62 is provided on the side of the support frame 61 near the motor housing material 2. A driven wheel 63 is provided at one end of the roller 62, and the driven wheel 63 is connected to the plug rod 17. The roller 62 can rotate on the support frame 61. The driven wheel 63 connected to the roller 62 contacts the plug rod 17, supporting the plug rod 17 and preventing it from shaking when rotating. When the plug rod 17 rotates, the driven wheel 63 will rotate synchronously with the plug rod 17.

[0029] The driven mechanism 6 maintains dynamic contact with the insertion rod 17 through its freely rotatable components, providing auxiliary support for the rotating insertion rod 17. When the insertion rod 17 performs indexing rotation under the drive motor 15, the rotating element in the driven mechanism 6 rolls synchronously, conforming to the rotation trend of the insertion rod 17 and applying a continuous radial constraint force along its entire circumference. This effectively suppresses the radial sway and eccentric vibration of the long, overhanging insertion rod 17 caused by center of gravity offset or driving torque fluctuation during rotation. At the same time, the intervention of the driven mechanism 6 does not add additional rotational resistance. Its follow-up characteristics ensure that the support force on the insertion rod 17 is always uniform and continuous, thereby ensuring the angular positioning accuracy and rotational stability of the motor housing material 2 during successive indexing changes. This avoids the cumulative angular deviation caused by drive shaft wobbling, providing a stable and accurate workpiece posture reference for subsequent grinding processes, fundamentally improving the defect of insufficient rotational support affecting the final outer surface processing quality.

[0030] The grinding mechanism 4 includes a support plate 41 mounted on the second slide 3, which is movable on the second slide 3. A connecting plate 42 is mounted on the support plate 41, and a rotary motor 43 is mounted on the connecting plate 42. An extension frame 44 is mounted on the output end of the rotary motor 43, which drives the extension frame 44 to rotate. A grinding motor 45 is mounted on the other end of the extension frame 44, and a grinding wheel 46 is mounted on the output end of the grinding mechanism 4. The grinding wheel 46 is used to grind the surface of the motor housing material 2. A fixing frame 47 is mounted on the other side of the connecting plate 42 connected to the rotary motor 43. A cleaning component 48 is mounted on one end of the fixing frame 47, which is used to rub the surface of the motor housing material 2. The support plate 41 has built-in rollers that can move on the second carriage 3. The rotary motor 43 drives the extension frame 44 to rotate, thereby ensuring that the grinding wheel 46 rotates even when it is obstructed, preventing accidental damage to the grinding wheel 46 and the motor housing material 2. The grinding motor 45 drives the grinding wheel 46 to rotate at high speed and contact the motor housing material 2 to grind the outer surface of the motor housing material 2. The cleaning component 48 is essentially made of sponge and is used to wipe away dust adhering to the surface of the motor housing material 2 due to grinding.

[0031] The second carriage 3 is equipped with a drag chain 31, which is connected to the support plate 41. The drag chain 31 is used to transmit the power required for the extension frame 44 to the support plate 41.

[0032] The driven mechanism 6 maintains dynamic contact with the insertion rod 17 through its freely rotatable components, providing auxiliary support for the rotating insertion rod 17. When the insertion rod 17 performs indexing rotation under the drive motor 15, the rotating element in the driven mechanism 6 rolls synchronously, conforming to the rotation trend of the insertion rod 17 and applying a continuous radial constraint force along its entire circumference. This effectively suppresses the radial sway and eccentric vibration of the long, overhanging insertion rod 17 caused by center of gravity offset or driving torque fluctuation during rotation. At the same time, the intervention of the driven mechanism 6 does not add additional rotational resistance. Its follow-up characteristics ensure that the support force on the insertion rod 17 is always uniform and continuous, thereby ensuring the angular positioning accuracy and rotational stability of the motor housing material 2 during successive indexing changes. This avoids the cumulative angular deviation caused by drive shaft wobbling, providing a stable and accurate workpiece posture reference for subsequent grinding processes, fundamentally improving the defect of insufficient rotational support affecting the final outer surface processing quality.

[0033] When the finishing mechanism for the outer surface of the motor housing is in use, the second cylinder 72 in the adjusting mechanism 7 is activated, driving the support frame 14 to retract along the limiting rod 13 away from the workstation via the push rod 73, thus making room for the installation of the motor housing material 2. Subsequently, the long, uncut cylindrical motor housing material 2 to be processed is hoisted and placed between the two sets of support blocks 12 on the base 11, completing the initial positioning. Next, the second cylinder 72 drives the support frame 14 back towards the motor housing material 2, allowing the insertion rod 17 on the limiting plate 16 to accurately insert into the end of the motor housing material 2 and lock it in place, completing the clamping. During this process, the adjusting mechanism 7 can also fine-tune the position of the support frame 14 according to the actual length of the material or casting error to ensure the accuracy of the clamping reference.

[0034] After clamping, the drive motor 15 starts, driving the connector rod 17 to rotate the raw material 2 around its own axis, precisely aligning the first surface to be processed on its outer wall with the working direction of the grinding mechanism 4. Before this rotation is executed, the first cylinder 53 in the support mechanism 5 retracts the extension rod 54, removing the support seat 55 from the position in contact with the outer wall of the raw material to avoid motion interference with the rotating raw material. After rotation, the first cylinder 53 drives the extension rod 54 to extend, causing the support seat 55 to re-fit against the outer wall of the raw material, providing additional rigid support in the middle or suspended area of ​​the raw material, effectively suppressing radial runout and processing chatter during grinding. At the same time, the roller 62 and driven wheel 63 in the driven mechanism 6 maintain dynamic contact with the rotating connector rod 17 and roll synchronously, applying a continuous radial constraint force in its entire circumferential direction, suppressing the radial sway and eccentric vibration generated by the long overhanging connector rod 17 during rotation, ensuring the angular positioning accuracy and rotational stability during indexing conversion.

[0035] Once a plane is precisely positioned, the grinding mechanism 4 begins operation. The support plate 41 feeds at a constant speed in a straight line along the second slide 3 from one end to the other, simultaneously driving the grinding wheel 46 to traverse the entire length of the plane. The grinding motor 45 drives the grinding wheel 46 to rotate at high speed, contacting and grinding the outer surface of the workpiece at a preset grinding depth. During this process, if the grinding wheel 46 encounters local defects such as casting protrusions, hard inclusions, or deformation on the surface of the raw material, the rotary motor 43 responds quickly, driving the extension frame 44 to deflect and retract around the axis, causing the grinding wheel 46 to actively retract away from the axis to buffer overload impact and avoid damage to the grinding tool from rigid collisions; after passing the defect area, the extension frame 44 automatically resets, allowing the grinding wheel 46 to return to the preset grinding depth and continue stable grinding. Meanwhile, the cleaning component 48, which moves along with the support plate 41, follows closely behind the grinding wheel 46 to wipe the freshly processed outer wall surface, promptly removing metal dust and grinding debris adhering to the workpiece surface due to high-temperature sintering or electrostatic adsorption during grinding. The cable chain 31 continuously supplies the power required by the grinding mechanism 4 during the long-stroke reciprocating movement of the support plate 41, ensuring continuous and uninterrupted operation.

[0036] After one surface is polished, the support mechanism 5 retracts from the support base 55, and the drive motor 15 drives the motor housing material 2 to perform precise indexing rotation, aligning the next surface to be processed on its outer wall with the polishing station. Then, the support mechanism 5 re-supports, and the polishing mechanism 4 feeds axially to polish the next surface. This cycle of indexing rotation, support switching, and axial feed polishing is repeated until all seven surfaces on the outer wall of the motor housing material 2 have been finely polished. Throughout the process, the driven mechanism 6 continuously provides stable follow-up support for the rotating insertion rod 17, ensuring the cumulative accuracy of long-term indexing conversion. Ultimately, through the coordinated operation of all mechanisms, efficient, stable, and automated precision machining of the entire outer surface of the long, uncut motor housing material 2 is achieved.
