[0005] In view of the problems in the prior art, the present invention provides an inner circle finishing device for a motor stator.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an inner circle finishing device for a motor stator, including a first limit support structure, a processing structure, and a second limit support structure. The side end of the first limit support structure is fixedly connected to the second limit support structure. The processing structure is movably connected to the first limit support structure and the second limit support structure, and a control seat is installed on the first limit support structure and the second limit support structure; The first limit support structure includes a limit control component and a support processing component. The support processing component is fixedly connected to the limit control component. The limit control component performs preliminary limiting, and the limit control component has an alternating operation function. The support processing component performs limiting during processing, so as to protect the stator housing during processing; The processing structure includes a finishing and processing component, which is used for bidirectional processing of the stator casing and can move symmetrically to trim the inner circle of the stator casing. The finishing and processing mechanism in the finishing and processing component fixes the docking combination mechanism. The docking combination mechanism cooperates with the supporting processing component and can be flexibly adjusted to perform processing and limiting of the stator casing. The trimming and processing mechanism adopts a horizontal processing method to process the inner circle of the stator casing.

[0007] Specifically, the limit control component includes a hydraulic machine base, a matching connecting seat, a first telescopic control rod, a contact block, an arc bracket, a docking shaft seat and a second telescopic control rod. A matching connecting seat is connected to one side of the hydraulic machine base, and the first telescopic control rod is telescopically connected to the matching connecting seat. A second telescopic control rod is provided on the side of the hydraulic machine base away from the matching connecting seat. The second telescopic control rod is telescopically connected in the hydraulic machine base, and the second telescopic control rod and the first telescopic control rod move in opposite directions. The front end of the second telescopic control rod is fixedly connected to the docking shaft seat, the front end of the docking shaft seat is fixedly connected to the arc bracket, and the arc bracket is fixedly connected to the contact block.

[0008] Specifically, the arc-shaped bracket is arranged in an arc shape, and the arc-shaped bracket is pre-fixed with the stator housing through a contact block. When the first telescopic control rod is contracted, the oil pressure in the hydraulic machine base is changed by cooperating with the connecting seat, acting on the second telescopic control rod, so that the second telescopic control rod is extended and adjusted on the hydraulic machine base.

[0009] Specifically, the supporting processing components include a docking bottom rod, a supporting grid frame, a movable limit frame, an electrically-controlled hydraulic telescopic rod and a matching groove. The supporting grid frame is fixedly connected to the docking bottom rod, the docking bottom rod is hingedly provided with an electrically-controlled hydraulic telescopic rod, the upper end of the electrically-controlled hydraulic telescopic rod is hingedly provided with a movable limit frame, and the movable limit frame is provided with a matching groove.

[0011] Specifically, the trimming mechanism includes a trimming wheel, a sheath housing, a first motor, and a movable connection block. The upper end of the movable connection block is fixedly installed with a first motor. The side end of the first motor is fixedly connected to the sheath housing. The center of the side end of the first motor is drivingly connected to the trimming wheel. The trimming wheel is rotatably connected to the center of the sheath housing. Through the structural settings of the first limit support structure and the second limit support structure, the limiting work of the stator housing is facilitated. The first limit support structure is composed of a limit control component and a support processing component. The limit control component can perform preliminary limiting, and the support processing component performs limiting work during processing. Among them, the control seat controls the operation start of the hydraulic machine seat. The hydraulic machine seat and the matching communication seat control the telescopic adjustment of the first telescopic control rod, and simultaneously control the reverse movement of the contact block, the arc-shaped bracket, the docking shaft seat, and the second telescopic control rod. When the first telescopic control rod contracts, at this time, the movable connection block operates, pushing the trimming wheel, the sheath housing, and the first motor towards the center of the stator housing. At this time, the contact block and the arc-shaped bracket move forward to limit the stator housing. When the movable connection block passes through, the first telescopic control rod resets, and at the same time, the contact block and the arc-shaped bracket are controlled to move backward, without affecting the subsequent inner circle processing of the stator housing.

[0012] Specifically, the trimming mechanism further includes a limit groove plate, a second motor, a fixed groove plate, a first docking movable block, a first rack, a control gear disk, a second rack, and a second docking movable block. The center of the bottom of the limit groove plate is installed with a second motor. The upper end of the second motor is drivingly connected to the control gear disk.

The movable limit frame is connected to the hinged cooperation block through the cooperation groove, and the electric control hydraulic telescopic rod is hinged with the docking bottom rod. When the electric control hydraulic telescopic rod is telescopically adjusted, at this time, the movable limit frame can be rotationally adjusted through the cooperation groove and the hinged cooperation block, so that the movable limit frame is firmly limited to the stator housing. The second motor in the trimming mechanism can control the rotation of the control gear disk, making the first rack and the second rack move symmetrically and reversely, changing the positions of the first docking movable block and the second docking movable block on the limit groove plate, and at the same time making the symmetrically arranged trimming wheel, sheath housing, first motor, and movable connection block move symmetrically. The first motor can perform the finishing work on the inner circle of the stator housing through the trimming wheel.

[0013] Specifically, the first docking movable block and the second docking movable block are arranged inside the limit groove plate, and the second motor drives the first rack and the second rack to move symmetrically and reversely through the control gear disk. The dressing wheel is arranged in a protruding structure, and the inner circle of the stator housing is processed by the rotation of the dressing wheel.

[0014] Specifically, a fixed combined bracket is fixedly connected to the upper end of the fixed groove plate. The upper end of the hinged mating block is hinged to the movable limit frame through the mating groove. The electro-hydraulic telescopic rod expands and contracts, so that the movable limit frame rotates and adjusts around the mating groove.

[0015] Specifically, when the first rack and the second rack move to the extreme state, there is a gap between the two dressing wheels at this time, and the dressing wheels reach the central extreme gap position of the stator housing at this time.

[0016] Advantages of the present invention: First, through the structural settings of the first limit support structure and the second limit support structure of the present invention, it is convenient to carry out the limit work of the stator housing. The first limit support structure is composed of a limit control component and a support processing component. The limit control component can perform preliminary limit, and the support processing component performs limit work during processing. Among them, the control seat controls the operation and start of the hydraulic machine seat. The hydraulic machine seat and the mating communication seat control the telescopic adjustment of the first telescopic control rod, and simultaneously control the reverse movement of the contact block, the arc-shaped clamping frame, the docking shaft seat, and the second telescopic control rod. When the first telescopic control rod contracts, the movable connection block runs at this time, pushing the dressing wheel, the sheath shell, and the first motor towards the center of the stator housing. At this time, the contact block and the arc-shaped clamping frame move forward to limit the stator housing. When the movable connection block passes through, the first telescopic control rod resets, and at the same time controls the contact block and the arc-shaped clamping frame to move backward, which does not affect the subsequent inner circle processing of the stator housing.

[0017] Second, through the structural settings of the support processing component of the present invention, the stator housing can be limited before processing. The movable limit frame is connected to the hinged mating block through the mating groove, and the electro-hydraulic telescopic rod is hinged to the docking bottom rod. When the electro-hydraulic telescopic rod expands and contracts, the movable limit frame can rotate and adjust through the mating groove and the hinged mating block at this time, so that the movable limit frame is firmly limited to the stator housing. The second motor in the dressing and processing mechanism can control the rotation of the control gear disk, so that the first rack and the second rack move symmetrically and reversely, changing the positions of the first docking movable block and the second docking movable block on the limit groove plate, and at the same time making the symmetrically arranged dressing wheel, sheath shell, first motor, and movable connection block move symmetrically. The first motor can perform the finishing work on the inner circle of the stator housing through the dressing wheel. Description of the drawings

The position-limiting control component 4 is fixedly connected to the support processing component 5. The position-limiting control component 4 performs preliminary position limiting, and the position-limiting control component 4 has a staggered operation function. The support processing component 5 is limited during processing, thereby protecting the stator housing 17 during processing. The processing structure 2 includes a finishing and processing component 18, which is used for bidirectional processing of the stator casing 17 and can move symmetrically to trim the inner circle of the stator casing 17. The finishing and processing mechanism 20 in the finishing and processing component 18 fixes the docking combination mechanism 19. The docking combination mechanism 19 cooperates with the supporting processing component 5 and can be flexibly adjusted to perform processing and limiting of the stator casing 17. The trimming and processing mechanism 20 adopts a horizontal processing method to process the inner circle of the stator casing 17.

[0024] The limit control component 4 includes a hydraulic machine base 6, a matching connecting seat 7, a first telescopic control rod 8, a contact block 9, an arc bracket 10, a docking shaft seat 11 and a second telescopic control rod 12. One side of the hydraulic machine base 6 is connected with a matching connecting seat 7, and the first telescopic control rod 8 is telescopically connected to the matching connecting seat 7. A second telescopic control rod 12 is provided on the side of the hydraulic machine base 6 away from the matching connecting seat 7. The second telescopic control rod 12 is telescopically connected in the hydraulic machine base 6, and the second telescopic control rod 12 and the first telescopic control rod 8 move in opposite directions. The front end of the second telescopic control rod 12 is fixedly connected to the docking shaft seat 11, the front end of the docking shaft seat 11 is fixedly connected to the arc bracket 10, and the contact block 9 is fixedly connected to the arc bracket 10.

[0025] The arc-shaped clamping frame 10 is arranged in an arc shape. The arc-shaped clamping frame 10 is pre-fixed to the stator housing 17 through the contact block 9. When the first telescopic control rod 8 contracts, the oil pressure in the hydraulic machine base 6 is changed through the cooperation of the communication seat 7, acting on the second telescopic control rod 12, so that the second telescopic control rod 12 extends and adjusts on the hydraulic machine base 6.

[0026] The support processing component 5 includes a butt bottom rod 13, a support grid frame 14, a movable limit frame 15, an electric control hydraulic telescopic rod 16 and a mating groove 39. The butt bottom rod 13 is fixedly connected to the support grid frame 14. An electric control hydraulic telescopic rod 16 is hinged on the butt bottom rod 13. The upper end of the electric control hydraulic telescopic rod 16 is hinged with a movable limit frame 15. A mating groove 39 is provided on the movable limit frame 15. Through the structural settings of the first limit support structure 1 and the second limit support structure 3, it is convenient to carry out the limiting work of the stator housing 17. The first limit support structure 1 is composed of a limit control component 4 and a support processing component 5. The limit control component 4 can perform preliminary limiting, and the support processing component 5 performs the limiting work during processing. Among them, the control seat 38 controls the operation start of the hydraulic machine base 6. The hydraulic machine base 6 and the communication seat 7 control the telescopic adjustment of the first telescopic control rod 8, and simultaneously control the reverse movement of the contact block 9, the arc-shaped clamping frame 10, the docking shaft seat 11 and the second telescopic control rod 12. When the first telescopic control rod 8 contracts, at this time the movable connection block 29 operates, pushing the dressing wheel 26, the sheath housing 27 and the first motor 28 towards the center of the stator housing 17. At this time, the contact block 9 and the arc-shaped clamping frame 10 move forward to limit the stator housing 17. When the movable connection block 29 passes through, the first telescopic control rod 8 resets, and at the same time controls the contact block 9 and the arc-shaped clamping frame 10 to move backward, without affecting the subsequent inner circle processing of the stator housing 17.

[0027] The docking combination mechanism 19 includes a hinged mating block 21, a fixed protection end frame 22, a positioning connecting frame 23, a support fixing seat block 24 and a fixed combination bracket 25. The upper end of the fixed combination bracket 25 is fixedly connected with the support fixing seat block 24. The positioning connecting frame 23 is fixedly connected to the support fixing seat block 24. The support fixing seat block 24 is fixedly connected with the fixed protection end frame 22 through the positioning connecting frame 23. The hinged mating block 21 is fixedly connected to the fixed protection end frame 22. The stator housing 17 can be placed on the inclined movable limit frame 15 by a manipulator. At this time, the movable limit frame 15 supports the stator housing 17. The symmetrically arranged movable limit frames 15 are in an open state. The movable limit frame 15 is connected to the hinged mating block 21 through the mating groove 39 and can rotate and adjust around the hinged mating block 21. When the stator housing 17 reaches the movable limit frame 15 and is stable, at this time the electric control hydraulic telescopic rod 16 works to push the movable limit frame 15, so that the movable limit frame 15 rotates around the mating groove 39 and the hinged mating block 21, and the symmetric movable limit frames 15 are closed to realize the stable support of the stator housing 17.

[0028] The trimming mechanism 20 includes a trimming wheel 26, a sheath housing 27, a first motor 28, and a movable connection block 29. When the movable connection block 29 is out of the monitoring range, the hydraulic machine base 6 at this time controls the first telescopic control rod 8 and the second telescopic control rod 12 to reset, and the contact block 9 no longer contacts the stator housing 17 to prevent processing interference. At this time, the first motor 28 operates to drive the trimming wheel 26 to rotate at the center of the sheath housing 27, and the trimming wheel 26 is connected to the inner ring of the stator housing 17 to perform leveling processing on the inner ring of the stator housing 17. The first motor 28 is fixedly installed at the upper end of the movable connection block 29, the side end of the first motor 28 is fixedly connected to the sheath housing 27, the center of the side end of the first motor 28 is drivingly connected to the trimming wheel 26, and the trimming wheel 26 is rotatably connected at the center of the sheath housing 27. The first telescopic control rod 8 is in an extended state, and the control base 38 can control the operation of the hydraulic machine base 6. At this time, the second motor 31 drives to drive the control gear disk 35 to rotate. The control gear disk 35 is meshed with the first rack 34 and the second rack 36, so that the symmetrically arranged first rack 34 and the second rack 36 move in opposite directions, changing the positions of the first docking movable block 33 and the second docking movable block 37 on the limit groove plate 30. At this time, the movable connection block 29 moves accordingly, and at the same time drives the trimming wheel 26, the sheath housing 27, and the first motor 28 to move. When the sensor detects the movement of the movable connection block 29, the control base 38 at this time controls the hydraulic machine base 6 to work, so that the first telescopic control rod 8 contracts to prevent interference with the operation of the movable connection block 29. And due to the pressure change, the hydraulic machine base 6 controls the second telescopic control rod 12 to extend, driving the contact block 9, the arc-shaped clamping frame 10, and the docking shaft seat 11 to displace accordingly. At this time, the arc-shaped clamping frame 10 can clamp and contact the stator housing 17 to strengthen the protection and support of the stator housing 17.

[0029] The trimming mechanism 20 further includes a limit groove plate 30, a second motor 31, a fixed groove plate 32, a first docking movable block 33, a first rack 34, a control gear disk 35, a second rack 36 and a second docking movable block 37. A second motor 31 is installed at the center of the bottom of the limit groove plate 30. The upper end of the second motor 31 is drivingly connected to a control gear disk 35. One side of the control gear disk 35 is meshed with a first rack 34, and the other side of the control gear disk 35 is meshed with a second rack 36. The upper end of the second rack 36 is fixedly connected to a second docking movable block 37, and the upper end of the first rack 34 is fixedly connected to a first docking movable block 33. Fixed groove plates 32 are symmetrically and fixedly connected to the front and rear ends of the limit groove plate 30. Through the structural arrangement of the support processing component 5, the stator housing 17 can be limited before processing. The movable limit frame 15 is connected to the hinged fitting block 21 through the fitting groove 39, and the electro-hydraulic telescopic rod 16 is hinged to the docking bottom rod 13. When the electro-hydraulic telescopic rod 16 expands and contracts, the movable limit frame 15 can rotate and adjust through the fitting groove 39 and the hinged fitting block 21, so that the movable limit frame 15 is firmly limited to the stator housing 17. The second motor 31 in the trimming mechanism 20 can control the rotation of the control gear disk 35, so that the first rack 34 and the second rack 36 move symmetrically and in opposite directions, changing the positions of the first docking movable block 33 and the second docking movable block 37 on the limit groove plate 30. At the same time, the symmetrically arranged trimming wheels 26, the sheath housing 27, the first motor 28 and the movable connecting block 29 move symmetrically. The first motor 28 can perform the finishing work on the inner circle of the stator housing 17 through the trimming wheels 26.

[0030] The first docking movable block 33 and the second docking movable block 37 are arranged inside the limit groove plate 30, and the second motor 31 drives the first rack 34 and the second rack 36 to move symmetrically and in opposite directions through the control gear disk 35. The trimming wheel 26 is arranged in a protruding structure. The trimming wheel 26 performs the inner circle processing of the stator housing 17 by rotating.

[0031] A fixed combination bracket 25 is fixedly connected to the upper end of the fixed groove plate 32. The upper end of the hinged fitting block 21 is hinged to the movable limit frame 15 through the fitting groove 39. The electro-hydraulic telescopic rod 16 expands and contracts, so that the movable limit frame 15 rotates and adjusts around the fitting groove 39.

[0032] When the first rack 34 and the second rack 36 move to the extreme state, there is a gap between the two trimming wheels 26 at this time, and the trimming wheels 26 reach the central extreme gap position of the stator housing 17 at this time.

[0033] The working principle is as follows: When in use, the manipulator can place the stator housing 17 on the inclined movable limit frame 15. At this time, the movable limit frame 15 supports the stator housing 17. The symmetrically arranged movable limit frames 15 are in an open state. The movable limit frame 15 is connected to the hinged mating block 21 through the mating groove 39 and can rotate and adjust around the hinged mating block 21. When the stator housing 17 reaches the movable limit frame 15 and is stable, the electro-hydraulic telescopic rod 16 works at this time, pushing the movable limit frame 15, so that the movable limit frame 15 rotates around the mating groove 39 and the hinged mating block 21, and the symmetric movable limit frames 15 are closed to achieve stable support for the stator housing 17; At this time, the first telescopic control rod 8 is in an extended state. The control seat 38 can control the operation of the hydraulic machine base 6. At this time, the second motor 31 drives, driving the control gear disk 35 to rotate. The control gear disk 35 is meshed and connected with the first rack 34 and the second rack 36, so that the symmetrically arranged first rack 34 and second rack 36 move in opposite directions, changing the positions of the first docking movable block 33 and the second docking movable block 37 on the limit groove plate 30. At this time, the movable connecting block 29 moves accordingly, and at the same time drives the trimming wheel 26, the sheath housing 27, and the first motor 28 to move. When the sensor detects the movement of the movable connecting block 29, the control seat 38 controls the hydraulic machine base 6 to work, so that the first telescopic control rod 8 contracts to prevent interference with the operation of the movable connecting block 29. And due to the pressure change, the hydraulic machine base 6 controls the second telescopic control rod 12 to extend, driving the contact block 9, the arc-shaped clamping frame 10, and the docking shaft seat 11 to follow the displacement. At this time, the arc-shaped clamping frame 10 can clamp and contact the stator housing 17 to strengthen the protective support for the stator housing 17; When the movable connecting block 29 is out of the monitoring range, the hydraulic machine base 6 controls the first telescopic control rod 8 and the second telescopic control rod 12 to reset, and the contact block 9 no longer contacts the stator housing 17 to prevent processing interference. At this time, the first motor 28 works, driving the trimming wheel 26 to rotate in the center of the sheath housing 27, and the trimming wheel 26 is connected to the inner ring of the stator housing 17 to perform leveling treatment on the inner ring of the stator housing 17 to complete the work.
