Description

Technical Field

[0001] This invention relates to the field of motor housing technology, specifically a grinding device for new energy motor housings. Background Technology

[0002] In the manufacturing process of new energy motor housings, precision grinding of the outer wall is a crucial step to ensure appearance quality, eliminate casting defects, and provide a qualified reference surface for subsequent painting or assembly. Currently, the machining of the cylindrical or polygonal outer surface of the motor housing often employs a method of fixing the workpiece and moving the tool, using an external grinding head or handheld grinder to process each surface of the housing. However, this method is limited by the segmented structure of the motor housing's outer circumference. Each surface machining often requires manual readjustment of the workpiece clamping posture or movement of the grinding equipment, making the operation cumbersome and prone to arbitrary positioning. Repeated clamping not only leads to excessive machining auxiliary time but also makes it difficult to guarantee the dimensional and positional tolerances between the machined surfaces due to multiple switching of clamping references. This easily results in tool marks, overlapping grinding, or missed areas, directly affecting the cylindricity of the outer circle of the motor housing and the smoothness of the surface transition.

[0003] Furthermore, existing open or semi-open grinding methods lack effective integration of workpiece rotation and grinding feed. Operators must rely on experience to control grinding pressure and stroke, which can easily lead to localized overheating or under-grinding of the outer surface, resulting in significant differences in roughness between different areas of the same housing. Simultaneously, the high-temperature metal dust generated during grinding is scattered everywhere, not only worsening the working environment and endangering the health of operators, but also increasing the difficulty of subsequent cleaning. These drawbacks are particularly prominent in mass production, severely restricting the automation level and quality consistency of the motor housing outer surface grinding process, becoming one of the main bottlenecks in the efficient and high-precision machining of new energy motor housings.

[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 1-8 This invention provides a technical solution: a grinding device for a new energy motor housing, used for grinding the motor housing 2. The main grinding area is the side shell of the motor housing 2, excluding the upper and lower ports of the motor housing 2. It includes: a housing 1, a rotating mechanism 3, and a grinding mechanism 4. The housing 1 houses the grinding mechanism for the motor housing 2. Grinding the motor housing 2 inside the housing 1 prevents grinding debris from flying and causing pollution or injury. The rotating mechanism 3 is located in the housing 1 and is used to clamp and rotate the motor housing 2. Since the outer shell of the motor housing 2 is divided into seven equal parts, the rotating mechanism 3 clamps and rotates the motor housing 2 to ensure that the entire surface of the motor housing 2 can be ground. The clamping is to ensure more stable grinding of the motor housing 2 and prevent tilting or tipping. The rotation is to ensure that the entire surface of the motor housing 2 can be ground. The grinding mechanism 4 is located in the outer casing 1 and is situated on one side of the rotating mechanism 3. The grinding mechanism 4 can also move up and down to ensure that when the motor housing 2 rotates to the side that needs to be ground, the grinding mechanism 4 can grind the motor housing 2 from top to bottom in all directions.

[0020] The motor housing 2 to be processed is fed into the outer shell 1 and clamped and fixed from the end or outer periphery by the rotating mechanism 3. The clamping action ensures that the motor housing 2 maintains axial stability during high-speed rotation and grinding, avoiding uneven grinding depth or workpiece flying out due to tilting or vibration. Subsequently, the rotating mechanism 3 rotates intermittently according to the seven-eighths circumferential feature of the outer shell of the motor housing 2, stopping after each division angle, so that the corresponding side area of ​​the motor housing 2 is facing the working position of the grinding mechanism 4. At the same time, the grinding mechanism 4, driven by itself, makes a reciprocating up-and-down feeding motion along the height direction of the outer shell 1, starting from the upper edge of the side of the motor housing 2 and continuously descending to the lower edge, completing the longitudinal grinding of the current division side. When the side is ground, the rotating mechanism 3 rotates to the next seven division angle, and the grinding mechanism 4 feeds from top to bottom again, and so on, until all seven sides of the motor housing 2 are evenly ground. Throughout the process, the outer shell 1 always surrounds the grinding area, trapping the metal chips and dust inside and preventing them from flying into the external environment. At the same time, the inner wall of the outer shell 1 can also work with dust suction or cooling airflow to remove grinding heat and chips in time, avoiding wear of the grinding wheel and thermal deformation of the workpiece, thereby ensuring that each equally divided side obtains a consistent surface roughness and dimensional accuracy.

[0021] The rotating mechanism 3 includes a rotary motor and a clamping mechanism. The rotary motor is located inside the rotating mechanism 3 and is used to drive the clamping mechanism and the motor housing 2 to rotate. The rotation is to adjust the angle that the motor housing 2 needs to be polished, to turn the plane that needs to be adjusted toward the polishing mechanism 4 and align it, and to ensure that the polishing mechanism 4 can polish the entire outer shell of the motor housing 2.

[0022] The clamping mechanism includes a clamping motor 31 located within the rotating mechanism 3 and connected to the rotary motor. When the clamping motor 31 drives the clamping mechanism to clamp and stabilize the motor housing 2, the rotary motor starts, causing the motor housing 2 to rotate. The clamping motor 31 has a connecting block 32, which is hollow and penetrating, used to transmit power from the clamping motor 31. The connecting block 32 is located at the output end of the clamping motor 31, stabilizing the connection of the clamping motor 31 without hindering its normal operation. The output end of the clamping motor 31 has a lead screw 311 that passes through the connecting block 32, ensuring that the power of the clamping motor 31 can be transmitted. A through hole is provided at the connection between the bearing plate 33 and the connecting block 32.

[0023] When the motor housing 2 is fed into the outer casing 1, the clamping motor 31 in the rotating mechanism 3 starts first, and its output end drives the lead screw 311 to rotate. The lead screw 311 passes through the hollow through-shaped connecting block 32 and transmits power to the execution end of the clamping mechanism, so that the clamping component gradually tightens along the direction of the bearing plate 33 until a stable and uniform clamping force is applied to the motor housing 2. During this process, the through hole opened on the bearing plate 33 provides axial movement clearance space for the lead screw 311 or related transmission rods, ensuring that the clamping stroke is not interfered with. After the clamping is secure, the clamping motor 31 remains locked to maintain a constant clamping force. Then, the rotary motor starts, which drives the entire clamping mechanism and the clamped motor housing 2 to rotate around its own axis through the connecting block 32. Each rotation is indexed according to a preset seven-division angle, so that the side of the motor housing 2 to be polished is precisely aligned with the working surface of the polishing mechanism 4. During the rotation, the lead screw 311 does not rotate relative to the clamping motor 31 because it is locked, thus ensuring that the clamping force will not fluctuate or loosen due to rotational inertia. At the same time, the hollow through-structure of the connecting block 32 serves as a torque transmission channel between the rotary motor and the clamping mechanism, and also allows the lead screw 311 to move freely within it. This ensures that the clamping and rotation actions do not interfere with each other in space, realizing a cyclical working mode of "clamping first, then indexing and rotating, with each rotation corresponding to one longitudinal polishing." This ensures that all seven equally divided sides of the motor housing 2 can be processed sequentially and completely without clamping deviation.

[0024] A support block 34 is provided on the support plate 33, and two support blocks are provided on the support block 34. A connecting shaft 35 is provided on the support block, and the connecting shaft 35 is used to allow the gripper 36 to rotate on the connecting shaft 35, thereby switching the placement state and the fixed state of the clamping mechanism. The connecting shaft 35 is provided with gripper 36, which is used to engage with the motor housing 2 to ensure that the motor housing 2 is clamped and fixed. The gripper 36 can rotate on the connecting shaft 35. There are three grippers 36, arranged in a circular array on the outside of the meshing plate 37. When rotating away from the lead screw 311, all the grippers 36 will open, so that the motor housing 2 can be placed on the clamping mechanism. When the grippers 36 rotate towards the lead screw 311, the grippers 36 will engage, thereby clamping the motor housing 2.

[0025] Before the motor housing 2 is placed in, the grippers 36 are initially in the open state, meaning the three grippers 36 rotate and open around the connecting shaft 35 in a direction away from the lead screw 311. Since the three grippers 36 are arranged in a circular array on the outside of the meshing plate 37, when they flip outwards simultaneously, they will form a sufficiently wide opening above the bearing plate 33, making it easy for the operator or robot to easily slip the motor housing 2 into the clamping area from above. After the motor housing 2 is placed in place, the drive element pushes the meshing plate 37 to move axially toward the lead screw 311. The meshing plate 37 simultaneously drives the three grippers 36 to rotate in the opposite direction around their respective connecting shafts 35, that is, to close toward the lead screw 311. At this time, the ends of the grippers 36 engage from the outside to the inside, gradually fitting against the outer wall of the motor housing 2, until the three grippers 36 evenly hug the motor housing 2 from the circumferential direction, achieving a self-centering clamping effect. During this process, the two bearing blocks on the support block 34 provide end support for the connecting shaft 35, ensuring that the connecting shaft 35 will not bend or shift when subjected to the radial reaction force during repeated rotation and friction of the gripper 36 and grinding. At the same time, the connecting shaft 35 serves as a fulcrum for rotation, allowing the opening angle and clamping stroke of the gripper 36 to be precisely controlled. This ensures both the ease of loading and unloading the motor housing 2 and provides sufficient and balanced clamping force in the fixed state, preventing deformation of the thin wall of the motor housing 2 due to excessive clamping force on one side. In addition, when the gripper 36 is in the clamped and fixed state, the elastic pad or anti-slip structure that can be added to its inner side will undergo slight deformation due to the clamping force, further compensating for the dimensional tolerance of the outer circumference of the motor housing 2. This ensures that the clamping mechanism maintains a reliable grip on the motor housing 2 during rotation, and even if the grinding mechanism 4 applies a large lateral cutting force, there will be no slippage or displacement.

[0026] A meshing plate 37 is provided on the support plate 33. A connecting pipe is located on the side of the meshing plate 37 closest to the support plate 33 and is inserted into the support plate 33. The connecting pipe is hollow and allows the lead screw 311 to pass through and mesh with the meshing plate 37. When the lead screw 311 rotates, it moves up and down on the support plate 33 due to its meshing with the meshing plate 37. The connecting pipe of the meshing plate 37 is inserted into the support plate 33 to ensure the stability of the meshing plate 37. The meshing plate 37 is driven by the lead screw 311 to move on the support plate 33, moving up and down. When the meshing plate 37 moves downwards, it causes the gripper 36 to rotate in the opposite direction to the lead screw 311; conversely, when the meshing plate 37 moves upwards, it causes the gripper 36 to rotate away from the lead screw 311.

[0027] A connecting groove 371 is provided on the meshing plate 37. One end of the adapter block 372 is connected to the connecting groove 371 via a connecting shaft 35. The other end of the adapter block 372 is connected to the gripper 36 via the connecting shaft 35. This design allows the adapter block 372 to connect the gripper 36 to the meshing plate 37. When the positional relationship between the meshing plate 37 and the support plate 33 changes, the resulting change will alter the rotation of the gripper 36. Both the upper and lower ends of the adapter block 372 can rotate, with the connecting shaft 35 on the support block 34 serving as a fulcrum, around which the gripper 36 will rotate.

[0028] During the clamping action, the clamping motor 31 drives the lead screw 311 to rotate. The lead screw 311 drives the meshing plate 37 to move up and down along the surface of the support plate 33 through the threaded engagement. Since the meshing plate 37 has a hollow connecting tube on the side near the support plate 33 and is inserted into the support plate 33, the connecting tube serves as a guide post to restrict the meshing plate 37 to move only axially without deflection, and also provides a channel for the lead screw 311 to pass through, thus ensuring that the meshing plate 37 remains stable when subjected to a large transmission load. When the lead screw 311 rotates in one direction, the meshing plate 37 moves downward. At this time, the meshing plate 37 pushes the upper end of the adapter block 372 through the connecting shaft 35 in the connecting groove 371. The lower end of the adapter block 372 pulls the middle part of the gripper 36 through another connecting shaft 35. Since the connecting shaft 35 on the support block 34 serves as a fixed fulcrum, the gripper 36 rotates around the fulcrum towards the lead screw 311, that is, it engages inward. Conversely, when the lead screw 311 rotates in the opposite direction, causing the meshing plate 37 to move upward, the adapter block 372 converts the lifting force of the meshing plate 37 into a pushing force on the middle of the gripper 36. The gripper 36 rotates around the fixed fulcrum in a direction away from the lead screw 311, that is, it opens outward. The gripper 36 includes a push block 361 and a contact point 362. The push block 361 and the adapter block 372 are connected, and the contact point 362 will contact the motor housing 2 in the fixed state, thereby fixing the motor housing 2.

[0029] During this process, both the upper and lower ends of the adapter block 372 can rotate around their respective connecting shafts 35, allowing the change in the angle between the linear motion of the meshing plate 37 and the rotational motion of the gripper 36 to be automatically compensated, avoiding motion interference. At the same time, the connecting groove 371 provides a fine-tuning allowance along the length of the groove for the connecting shaft 35, which is used to absorb the travel deviation caused by part machining errors or assembly deviations, ensuring that the three grippers 36 open and close synchronously and symmetrically on the circular array. In addition, the travel of the meshing plate 37 and the rotation angle of the gripper 36 are in a fixed proportional relationship. When the meshing plate 37 moves to the lower limit position, the clamping angle of the gripper 36 reaches its maximum. At this time, the clamping force generated by the inner side of the gripper 36 on the outer wall of the motor housing 2 also reaches the set value, and this position can be precisely positioned by the number of rotations of the lead screw 311, thereby realizing the adjustable clamping force for motor housings 2 of different diameters, ensuring that the workpiece does not loosen during the grinding process, and avoiding elastic deformation of the thin-walled housing due to over-clamping.

[0030] A support structure 38 is provided on the support plate 33 to support the motor housing 2. The support structure 38 includes a support column 381 on the support plate 33, which is used to stably support the base 382 to ensure stable support for the motor housing 2. The support column 381 is provided with a base 382, ​​and the base 382 has an adapter groove 383 for accommodating the rotation range of the gripper 36. So when the gripper 36 clamps and rotates the motor housing 2, the gripper 36 will rotate within the adapter groove 383.

[0031] When the motor housing 2 is placed above the support plate 33, the support column 381 in the support structure 38 fixes the base 382 from below. The upper end face of the base 382 directly supports the bottom edge or lower end face of the motor housing 2, providing a horizontal and stable support platform for the motor housing 2. This allows the motor housing 2 to maintain a vertical posture before being clamped by the gripper 36, preventing it from tilting due to instability. At the same time, the support column 381 vertically transmits the weight of the motor housing 2 on the base 382 and the downward pressure generated during grinding to the support plate 33, which then distributes the force to the entire housing of the rotating mechanism 3, thereby effectively suppressing the up-and-down vibration caused by the cutting force during grinding. When the gripper 36 performs the opening and closing action, the adapter groove 383 through the base 382 provides sufficient space for the rotation path of the three grippers 36. When the gripper 36 rotates around the connecting shaft 35 towards the lead screw 311 to engage, the lower end of the gripper 36 will enter the recessed area of ​​the adapter groove 383. The groove wall will not hinder the swing of the gripper 36, ensuring that the gripper 36 can be fully retracted to the clamping position that fits against the outer wall of the motor housing 2. Conversely, when the gripper 36 rotates away from the lead screw 311 to open, the adapter groove 383 also allows the lower part of the gripper 36 to exit outward without interfering with the base 382. Furthermore, the depth and width of the adapter slot 383 are designed to ensure that the gripper 36 maintains a non-contact gap with the base 382 at different opening angles. This avoids collision and wear between metal parts and prevents debris or dust from accumulating in the slot due to excessive gaps, thus affecting the flexible rotation of the gripper 36. At the same time, the upper surface of the base 382 can also serve as a reference surface for axial positioning of the motor housing 2. When the lower end face of the motor housing 2 is in contact with the base 382, ​​the engagement position of the gripper 36 is relatively fixed, thereby ensuring that the grinding starting height of the motor housing 2 is consistent after each clamping. This is beneficial for the grinding mechanism 4 to achieve accurate and repeatable positioning along the feed stroke of the outer shell 1.

[0032] The grinding mechanism 4 includes a rack 41 housed within the outer casing 1, with a gear compartment 42 engaged on the rack 41. A drive electrical box 43 is located on the outer side of the gear compartment 42. The gear compartment 42 contains gears meshing with it and a movable motor that drives the gears to rotate. The movable motor is driven by the drive electrical box 43. When the drive electrical box 43 drives the movable motor within the gear compartment 42 to rotate the gears, the drive electrical box 43 moves up and down on the surface of the rack 41.

[0033] A grinding motor 44 is also provided on the outside of the drive box 43. The output end of the grinding motor 44 is provided with a grinding wheel 45 for machining the motor housing 2. While the drive box 43 carries the grinding motor 44 to move up and down, the grinding motor 44 drives the grinding wheel 45 to rotate, and grinds one side of the motor housing 2 clamped on the rotating mechanism 3.

[0034] After receiving the control command, the drive box 43 drives the moving motor in the gearbox 42 to operate. The moving motor drives the gear at its output end to rotate. This gear meshes with the rack 41 fixed to the inner wall of the outer shell 1. Since the rack 41 is stationary, the rotational motion of the gear is converted into a linear reciprocating motion of the entire gearbox 42 and the drive box 43 fixed to it along the length of the rack 41, that is, moving up and down along the height of the outer shell 1. While the drive box 43 moves up and down, the grinding motor 44 fixedly installed on its outer side starts synchronously. The output end of the grinding motor 44 drives the grinding wheel 45 to rotate at high speed. The circumferential working surface of the grinding wheel 45 always faces the side of the motor housing 2 clamped on the rotating mechanism 3. When the drive box 43 feeds from top to bottom or from bottom to top, the rotating grinding wheel 45 applies a continuous grinding action to the side of the motor housing 2 that is currently facing, completing the complete grinding stroke of that side from top to bottom. During this process, the moving speed of the drive box 43 and the rotation speed of the grinding motor 44 can be adjusted independently. The moving speed determines the length of the workpiece surface swept by the grinding wheel 45 per unit time, while the rotation speed of the grinding wheel 45 determines the number of cuts and the grinding depth per unit area. The two work together to adapt to the grinding process requirements of motor housing 2 with different wall thicknesses or different materials. At the same time, the meshing of the rack 41 and the gear in the gear compartment 42 has a self-locking characteristic. When the moving motor stops running, the drive box 43 can be stably stopped at any height position of the rack 41, thereby allowing the grinding wheel 45 to perform fixed-point fine grinding or reciprocating polishing in a specific area on the side of the motor housing 2. Furthermore, the rotation direction of the grinding wheel 45 is perpendicular to the feed direction of the drive box 43, so that the tangential force generated by the grinding wheel 45 when it contacts the surface of the motor housing 2 forms a compound cutting effect with the feed force. This not only improves the material removal efficiency, but also carries away the grinding heat along the tangential direction of the grinding wheel 45 through the rotational motion, avoiding excessive heat concentration in the local area of ​​the workpiece. The vertical stroke range of the drive box 43 is set to cover the upper edge to the lower edge of the side of the motor housing 2, and the end of the stroke can be precisely stopped by the limit switch at the end of the rack 41 or the program soft limit, ensuring that the grinding area of ​​each side is neither missed nor exceeded. After the current side is ground, the drive box 43 can quickly return to the upper or lower starting position of the rack 41, waiting for the rotating mechanism 3 to rotate the next equally divided side to the working position, thus entering the next cycle.

[0035] The outer casing 1 has a mounting chamber 11 on the upper side of the rotating mechanism 3. The mounting chamber 11 can rotate within the outer casing 1. When the mounting chamber 11 is opened, the motor housing 2 can be mounted on the rotating mechanism 3. The outer casing 1 also has a cleaning chamber 12 on the outside of the grinding mechanism 4. The cleaning chamber 12 is used to clean the debris generated by the grinding wheel 45 grinding the motor housing 2. A chip discharge hole 14 is opened in the cleaning chamber 12 in the outer casing 1. The position of the chip discharge hole 14 corresponds to the position of the grinding wheel 45. In this way, most of the debris and dust generated when the grinding wheel 45 grinds the motor housing 2 will be discharged outward through the chip discharge hole 14. The outer side of the outer casing 1 also has a control panel 13. The control panel 13 is used to control and adjust the entire device, including the rotation angle, clamping force, vertical adjustment position, and the start time of the grinding wheel 45, etc.

[0036] During the clamping process, the operator first issues an unlocking command through the control panel 13, and the placement chamber 11 rotates and opens to the outside of the outer shell 1, exposing the operating space above the rotating mechanism 3. At this time, the operator can easily place the motor shell 2 onto the base 382 of the bearing structure 38. After clamping, the placement chamber 11 rotates back in the opposite direction and closes tightly, so that the entire outer shell 1 forms a closed grinding chamber, which effectively prevents metal chips from splashing into the external environment during subsequent processing. At the same time, the closed chamber can also significantly reduce the interference of grinding noise to the outside world. During the grinding process, the cleaning chamber 12 remains open or is started intermittently according to the setting. It can be connected to a dust suction pipe or an air nozzle to continuously remove or blow away the high-temperature metal chips and dust generated in the contact area between the grinding wheel 45 and the side of the motor shell 2 from the processing surface, avoiding the accumulation of chips between the workpiece and the grinding wheel 45 and causing secondary scratches. It also prevents chips from falling into the movement gaps such as the adapter groove 383 and the connecting groove 371, which would affect the flexible rotation of the gripper 36 and the adapter block 372. All actions of the entire device are centrally controlled by the control panel 13. The operator can preset the seven equal angle values ​​of each rotation of the rotating mechanism 3, the output torque of the clamping motor 31 to adjust the clamping force of the jaw 36, the vertical travel range and moving speed of the drive box 43 on the rack 41, and the start, stop and speed of the grinding motor 44 through the control panel 13. It can even set the number of grinding times on one side and the reciprocating strategy of the feed path. The control unit inside the control panel 13 will automatically coordinate the timing of the indexing rotation of the rotating mechanism 3 and the lifting and lowering feed of the grinding mechanism 4 according to the set parameters. It ensures that the grinding wheel 45 is started to move downward only after the jaw 36 is stably engaged and the motor housing 2 is completely stationary, and the rotating mechanism 3 is allowed to make the next indexing rotation only after the grinding wheel 45 is removed from the workpiece surface, so as to avoid motion interference that causes the grinding wheel 45 to collide or the jaw 36 to loosen. Meanwhile, the control panel 13 can also monitor the current and temperature of each motor in real time. When the grinding resistance of the grinding wheel 45 is too high or the drive box 43 is overloaded, it will automatically alarm and stop operation. After the operator observes the internal condition through the cleaning chamber 12 and eliminates the abnormality, the processing can be resumed through the control panel 13, thereby realizing the safe, controllable and automated operation of the entire grinding process.

[0037] When using the grinding device for the new energy motor housing, the operator issues an unlocking command through the control panel 13 on the outside of the housing 1. The mounting chamber 11 located on the upper side of the rotating mechanism 3 rotates outward and opens, revealing the internal operating space. At this time, the three grippers 36 are in the open state—that is, the three grippers 36 rotate around the connecting shaft 35 set on the support block 34 in a direction away from the lead screw 311, forming an opening above the bearing plate 33. The operator or robot arm places the motor housing 2 onto the base 382 of the bearing structure 38 on the bearing plate 33. The upper end face of the base 382 supports the lower end face of the motor housing 2, and the support column 381 vertically transmits the gravity to the bearing plate 33 to ensure vertical stability. After the motor housing 2 is placed in place, the mounting chamber 11 rotates back in the opposite direction and closes tightly, so that the entire housing 1 forms a closed grinding chamber.

[0038] The clamping action is then executed: the clamping motor 31 in the rotating mechanism 3 starts, and its output end drives the lead screw 311 to rotate. The lead screw 311 passes through the hollow through-shaped connecting block 32 and is threaded into the hollow connecting tube on the lower side of the meshing plate 37. The rotation of the lead screw 311 drives the meshing plate 37 to move downward along the surface of the bearing plate 33. The connecting tube of the meshing plate 37 is inserted into the bearing plate 33 to ensure that it only moves axially without deflection. When the meshing plate 37 descends, it pushes the upper end of the adapter block 372 through the connecting shaft 35 in the connecting groove 371, and the lower end of the adapter block 372 is pulled by another connecting shaft 35. In the middle of the moving jaw 36, due to the connecting shaft 35 on the support block 34 serving as a fixed fulcrum, the three jaws 36, arranged in a circular array on the outside of the meshing plate 37, synchronously retract and engage around their respective fulcrums towards the lead screw 311. The lower ends of the jaws 36 enter the fitting grooves 383 on the base 382, ​​and the ends adhere to and grip the outer wall of the motor housing 2 from the outside, achieving self-centering clamping. The upper and lower ends of the fitting block 372 can rotate around the corresponding connecting shaft 35 to compensate for changes in the motion angle. The connecting groove 371 provides a fine-tuning margin to absorb assembly deviations, ensuring that the three jaws open and close synchronously and symmetrically. After the clamping is stable, the clamping motor 31 locks to maintain a constant clamping force. The through hole at the connection between the bearing plate 33 and the connecting block 32 provides axial clearance space for the lead screw 311. Then the rotary motor starts, and through the hollow connecting block 32, it drives the entire clamping mechanism and the clamped motor housing 2 to rotate around its own axis. Based on the seven-part circumferential feature of the motor housing 2, it rotates intermittently according to the preset seven-part step angle. It stops after rotating one part angle, so that the corresponding side faces the working surface of the grinding mechanism 4.

[0039] Once one side is in place, the grinding mechanism 4 begins longitudinal grinding: the drive box 43 receives the command from the control panel 13 and drives the moving motor in the gearbox 42 to operate. The gear at the output end of the moving motor meshes with the rack 41 fixed to the inner wall of the outer casing 1. Since the rack 41 is stationary, the rotation of the gear is converted into the up-and-down linear motion of the gearbox 42 and the drive box 43 along the length of the rack 41. At the same time, the grinding motor 44 on the outside of the drive box 43 starts, driving the grinding wheel 45 to rotate at high speed. The circumferential working surface of the grinding wheel 45 always faces the current side of the motor housing 2. When the drive box 43 feeds from top to bottom, the rotating grinding wheel 45 applies continuous grinding to this side, completing the complete longitudinal grinding from top to bottom. The moving speed of the drive box 43 and the rotation speed of the grinding motor 44 can be independently adjusted to adapt to different process requirements. The self-locking characteristic of the rack 41 meshing with the gear allows the drive box 43 to be stably stopped at any height for fixed-point fine grinding. The rotation direction of the grinding wheel 45 is perpendicular to the feed direction to form a compound cutting effect and remove grinding heat. The upper and lower stroke range covers the upper and lower edges of the side and is precisely stopped by limit switches or soft limits.

[0040] After single-sided grinding is completed, the drive box 43 returns to the starting position, the rotating mechanism 3 rotates to the next seven-eighths angle, and the grinding mechanism 4 feeds from top to bottom again. This cycle continues until all seven sides are evenly ground. Throughout the entire processing, the outer shell 1 always surrounds the grinding area to prevent debris from flying and reduce noise. The cleaning chamber 12 on the outer shell 1 is connected to a dust suction pipe or air nozzle to continuously remove or blow away the high-temperature metal debris generated in the contact area between the grinding wheel 45 and the motor housing 2, avoiding debris accumulation that could cause secondary scratches, and also preventing debris from falling into the movement gaps such as the adapter groove 383 and the connecting groove 371, which could affect the flexible rotation of the gripper 36 and the adapter block 372. All actions of the entire device, such as rotation angle, clamping force, vertical stroke position, grinding wheel 45 start time, and number of grinding cycles per side, are centrally controlled by the control panel 13 on the outside of the outer casing 1. The control unit inside the control panel 13 automatically coordinates the indexing rotation of the rotating mechanism 3 and the lifting and feeding sequence of the grinding mechanism 4—ensuring that the gripper 36 is stably engaged and the motor housing 2 is completely stationary before starting the grinding wheel 45 to descend, and allowing the next indexing rotation only after the grinding wheel 45 has retracted from the workpiece surface, thus avoiding motion interference. The control panel 13 also monitors the current and temperature of each motor in real time, and automatically alarms and pauses when overload or excessive grinding resistance occurs. Processing can be resumed after the operator observes the internal condition through the cleaning chamber 12 and eliminates the abnormality, thereby realizing a safe, controllable, and automated full-process grinding operation.
