Description

Technical Field

[0001] This invention relates to the field of motor housing turning technology, and in particular to a turning apparatus for machining motor housings. Background Technology

[0002] In existing technology, turning apparatus for machining motor housings typically includes an operating table, a spindle, a three-jaw chuck, a tool post, and a turning tool. When machining an automotive motor housing, the housing is self-centeringly held by the three-jaw chuck, causing it to rotate with the spindle. The tool post drives the turning tool to feed, thereby turning the inner hole of the motor housing. For bearing holes, oil seal holes, or reducer interface holes on the automotive motor housing that are eccentric to the overall geometric center of the housing, it is usually necessary to add an eccentric shim, eccentric sleeve, or special eccentric fixture between the three-jaw chuck and the motor housing to ensure that the axis of the hole to be turned is aligned with the spindle axis.

[0003] However, the existing devices have the following drawbacks: the dedicated eccentric fixture has poor versatility, and different specifications or different electric drive platforms of automotive motor housings often require different fixtures, increasing manufacturing costs and changeover time. When rotating eccentrically, it will generate large centrifugal force and periodic vibration. The three-jaw chuck lacks external dynamic support, which can easily lead to tool deflection and vibration during turning, resulting in out-of-tolerance hole diameter, roundness, and surface roughness. The radial stability of the chuck and motor housing relative to the spindle is insufficient, and it is easy to cause slight displacement under the action of cutting force. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a turning device for machining motor housing, so as to solve the problem that the radial stability of the chuck and motor housing relative to the spindle is insufficient and that they are prone to slight displacement under the action of cutting force.

[0016] The beneficial effects of this invention are:

[0017] By adjusting the structure to adjust the position of the rotary seat relative to the rotating shell, the axis of the hole to be machined on the motor housing coincides with the rotation axis of the rotating shell. This allows the eccentric hole to rotate around its own axis when the rotating mechanism drives the rotating shell to rotate, facilitating machining. Through the cooperation of the mounting slot, positioning fixture, positioning groove, and positioning mechanism, the positioning fixture and the motor housing are positioned separately, preventing the motor housing from shifting relative to the rotary seat during machining.

[0018] The rotary support structure supports the adjusted rotary seat, suppressing radial wobble relative to the rotary shell and preventing slight misalignment under cutting forces. This improves the dimensional accuracy and surface quality of the eccentric hole turning. The adjustment structure handles the synchronous rotational transmission between the rotary shell and the rotary seat, while the rotary support structure ensures the stability of the adjusted rotary seat, enhancing the overall rigidity of the device. The drive mechanism moves the turning tool first along the avoidance direction and then along the feed direction, facilitating the disassembly and assembly of the motor housing and its turning operations. By changing the positioning fixtures to fit different motor housings, the same device can adapt to the eccentric hole turning requirements of various motor housing specifications.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0032] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention includes an operating table 1, a rotary seat 2 and a turning tool 9 disposed above the operating table 1. The rotary seat 2 has a mounting groove 3 on the side facing the turning tool 9. A positioning fixture 4 is provided in the mounting groove 3. The positioning fixture 4 has a positioning groove 5 on the side facing the turning tool 9 for positioning the position of the motor housing 10. The rotary seat 2 is equipped with positioning mechanisms for positioning the positions of the motor housing 10 and the positioning fixture 4 respectively. The operating table 1 is equipped with a drive mechanism for driving the turning tool 9 to move along the feed direction to perform turning. The drive mechanism can also drive the turning tool 9 to move along the avoidance direction to avoid the motor housing 10. The feed direction and the avoidance direction are perpendicular to each other.

[0033] A frame 6 is provided on the side of the rotary seat 2 away from the turning tool 9. The bottom end of the frame 6 is fixedly connected to the operating table 1. A rotating shell 8 is provided between the frame 6 and the rotary seat 2. A rotator for driving the rotating shell 8 to rotate is installed on the frame 6. An adjustment structure for adjusting the position of the rotary seat 2 is installed on the rotating shell 8. A rotating support structure that cooperates with the rotary seat 2 is installed on the frame 6.

[0034] When this device is in operation, the turning tool 9 is first driven by the drive mechanism to move in the avoidance direction, moving the turning tool 9 away from the rotary table 2 and the subsequent clamping area, thereby providing clearance space for the installation of the motor housing 10 and the positioning fixture 4. Based on this, the operator selects the positioning fixture 4 that matches the specifications of the motor housing 10 to be processed, and installs the positioning fixture 4 in the mounting groove 3 of the rotary table 2. Subsequently, the positioning mechanism positions the positioning fixture 4, fixing it relative to the rotary table 2.

[0035] Next, by adjusting the structure, the rotating seat 2 and the positioning fixture 4 are moved relative to the rotating shell 8, so that the axis of the inner hole to be machined on the motor housing 10 is aligned with the rotation axis of the rotating shell 8. After the rotating seat 2 is adjusted into place, it is supported by the rotating support structure, so that the rotating seat 2 is constrained in the radial direction relative to the rotating shell 8, preventing the rotating seat 2 from wobbling relative to the rotating shell 8 during subsequent rotation. Then, the motor housing 10 to be machined is inserted into the positioning slot 5, and the positioning mechanism is used to position the motor housing 10, so that the motor housing 10 is fixed relative to the positioning fixture 4 and the rotating seat 2.

[0036] Subsequently, the turning tool 9 is moved to the turning station by the drive mechanism; simultaneously, the rotating shell 8 is driven to rotate by the rotator, and the rotating shell 8 drives the rotating seat 2, the positioning fixture 4, and the motor housing 10 to rotate synchronously through the adjustment structure. Based on this, the drive mechanism drives the turning tool 9 to move towards the motor housing 10 along the feed direction, and the turning tool 9 can then turn the rotating motor housing 10. Since the adjustment structure has aligned the axis of the hole to be turned on the motor housing 10 with the axis of rotation of the rotating shell 8, the eccentric hole on the motor housing 10 can be turned; at the same time, the rotary support structure supports the rotating seat 2 after it has been adjusted to position, preventing the rotating seat 2 and the motor housing 10 from rotating and wobbling relative to the rotating shell 8. The adjustment structure mainly undertakes the synchronous rotational transmission between the rotating shell 8 and the rotating seat 2, while the rotary support structure mainly undertakes the rotational stability of the rotating seat 2 after it has been adjusted to position. The two functions are separate but work together to improve the turning stability.

[0037] Example 2, based on Example 1, is... Figure 2 , Figure 5 and Figure 6The adjustment structure includes a support plate 22 disposed within the rotating shell 8. The support plate 22 and the rotating base 2 are fixedly connected by a connecting column 23. A rectangular hole 24 is provided on the inner wall of the rotating shell 8 to mate with the connecting column 23. A pressing component that mates with the support plate 22 is mounted on the frame 6. The pressing component includes a pressing plate 25 disposed on the side of the support plate 22 away from the connecting column 23. A plurality of guide holes 26 are provided on the pressing plate 25. A guide column 27 is slidably disposed within the guide holes 26. The guide column 27 is fixedly connected to the inner wall of the rotating shell 8. A rotating shaft 28 is fixedly connected to the side of the pressing plate 25 away from the support plate 22. A fixing frame is fixedly connected to the side of the frame 6 away from the rotating shell 8. 30. A sliding seat 29 is slidably sleeved on the fixed frame 30. A first hydraulic push rod 31 is fixedly connected to the fixed frame 30, and the telescopic end of the first hydraulic push rod 31 is fixedly connected to the sliding seat 29. A rotating shaft 28 passes through the rotating shell 8 and the frame 6 and is rotatably connected to the sliding seat 29. The self-rotator includes a first servo motor 33 fixedly installed on the frame 6. A gear 34 is fixedly connected to the output end of the first servo motor 33. A rotating sleeve 32 is sleeved on the outside of the rotating shaft 28. The rotating sleeve 32 passes through the frame 6 and is fixedly connected to the rotating shell 8. The rotating sleeve 32 is rotatably connected to the frame 6. A gear ring 35 is fixedly sleeved on the outside of the rotating sleeve 32, and the gear ring 35 and the gear 34 mesh with each other.

[0038] When the positioning fixture 4 is installed in the mounting slot 3, the first hydraulic push rod 31 drives the sliding seat 29 to slide relative to the fixed frame 30. Based on the connection relationship between the sliding seat 29 and the rotating shaft 28, the sliding seat 29 drives the pressing plate 25 to slide relative to the guide post 27 through the rotating shaft 28, so that the pressing plate 25 no longer presses tightly against the support plate 22. Thus, the operator can drive the support plate 22, the connecting post 23, and the rotating seat 2 to slide and rotate relative to the rectangular hole 24, so that after the motor housing 10 is installed in the positioning slot 5, the axis of the inner hole to be machined on the motor housing 10 is aligned with the axis of rotation of the rotating shell 8. After the position of the rotating seat 2 is adjusted, the first hydraulic push rod 31 drives the sliding seat 29 to move in the opposite direction relative to the fixed frame 30, so that the rotating shaft 28 drives the pressing plate 25 to press against the support plate 22, thereby fixing the support plate 22 relative to the pressing plate 25 and the rotating shell 8. Subsequently, the first servo motor 33 drives the gear 34 to rotate, and the gear 34 drives the rotating sleeve 32 and the rotating shell 8 to rotate through the gear ring 35. The rotating shell 8 drives the pressing plate 25 to rotate synchronously through the guide post 27. The support plate 22, which is clamped and fixed between the pressing plate 25 and the inner wall of the rotating shell 8, rotates synchronously. The support plate 22 can then drive the rotating seat 2 and the motor housing 10 to rotate synchronously through the connecting post 23, thereby turning the inner hole of the motor housing 10. In this way, the continuous coordination of adjustment, locking and synchronous rotation transmission is achieved, which not only ensures that the eccentric position is adjustable, but also ensures that the power transmission is reliable after adjustment.

[0039] Example 3, based on Example 1, is... Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The rotary support structure includes a limiting sleeve 7 mounted on the frame 6. The rotary seat 2 has at least three telescopic support units for rolling contact with the inner wall of the limiting sleeve 7, and these telescopic support units are evenly distributed circumferentially around the outside of the rotary seat 2. A blocking ring 51 is fixedly fitted around the outside of the rotary seat 2, and both the limiting sleeve 7 and the telescopic support units are located on the side of the blocking ring 51 away from the turning tool 9. The positioning mechanism includes movable plates 36 and blocking seats 37 respectively mounted on both sides of the blocking ring 51. The blocking ring 51 has clearance holes 38 that cooperate with the movable plates 36. The movable plates 36 pass through the clearance holes 38 and are fixedly connected to the blocking seats 37, with the blocking seats 37 located on the side of the blocking ring 51 facing the turning tool 9. On the side, the shielding seat 37 and the shielding ring 51 are in contact. The shielding seat 37 is used to shield the clearance hole 38. The shielding seat 37 and the rotating seat 2 are connected by several compression springs 40. Several second insert rods 39 are fixedly connected to both the movable plate 36 and the shielding seat 37. The ends of the second insert rods 39 pass through the rotating seat 2 and the positioning fixture 4 and extend into the positioning groove 5. The second insert rods 39 are used to insert into the mounting holes on the motor housing 10. A supporting mechanism that cooperates with the movable plate 36 is installed on the frame 6. The supporting mechanism includes a second hydraulic push rod 43 fixedly installed on the frame 6. The limiting sleeve 7 is composed of a first arc plate 41 and a second arc plate 42. The first arc plate 41 is fixedly connected to the frame 6, and the second arc plate 42 slides. Mounted on the frame 6, with the telescopic end of the second hydraulic push rod 43 fixedly connected to the second arc plate 42, the movable plate 36 on the side away from the rotating seat 2 is provided with several telescopic support units for rolling contact with the inner wall of the limiting sleeve 7. Each telescopic support unit includes a first lead screw 13 and a threaded sleeve 14 threaded onto the outside of the first lead screw 13. The first lead screw 13 on the rotating support structure is rotatably connected to the rotating seat 2, and the first lead screw 13 on the supporting mechanism is rotatably connected to the movable plate 36. A support frame 11 is fixedly connected to the end of the threaded sleeve 14 away from the first lead screw 13. Rollers 11 are rotatably connected to the support frame 11 for rolling contact with the inner side of the first arc plate 41 or the second arc plate 42, respectively. 2. A support part 16 is fixedly connected to the threaded sleeve 14. A guide plate 15 slides through the support part 16. The guide plate 15 located on the rotating support structure is fixedly connected to the rotating seat 2. The guide plate 15 located on the supporting mechanism is fixedly connected to the movable plate 36. A fixing ring 17 is fixedly sleeved on the outside of the first lead screw 13. Multiple slots 18 are opened on the fixing ring 17 in a circular arrangement. A first insert rod 19 slides through the guide plate 15. One end of the first insert rod 19 is located in the corresponding slot 18. The other end of the first insert rod 19 is fixedly connected to the movable plate 20. A tension spring 21 is sleeved on the outside of the first insert rod 19. The two ends of the tension spring 21 are fixedly connected to the movable plate 20 and the guide plate 15, respectively.

[0040] After the position of the rotating seat 2 relative to the rotating shell 8 is adjusted, the operator drives the movable disk 20 and the first insertion rod 19 on the rotating support structure and positioning mechanism to move, so that the first insertion rod 19 disengages from the corresponding slot 18. At this time, the tension spring 21 is in a stretched state, thereby releasing the restriction on the position of the first lead screw 13. Based on this, the operator drives the first lead screw 13 to rotate, and the first lead screw 13 can drive the threaded sleeve 14 and the support part 16 to slide relative to the guide plate 15, so that the rollers 12 on the support frame 11 abut against the inner side of the corresponding first arc plate 41 or second arc plate 42, and the side of the movable plate 36 away from the rollers 12 abuts against the rotating seat 2, and the compression spring 40 is in a compressed state. After the position of the roller 12 is adjusted, the operator releases the movable plate 20, and the tension spring 21 drives the movable plate 20 and the first insertion rod 19 to move, so that the end of the first insertion rod 19 is inserted into the corresponding slot 18, thereby preventing the fixing ring 17 and the first lead screw 13 from rotating and shaking due to non-human factors, and ensuring that the roller 12 always abuts against the inner wall of the first arc plate 41 or the second arc plate 42.

[0041] The rotating seat 2 is supported by several rollers 12 on the rotating support structure to prevent the adjusted rotating seat 2 from wobbling relative to the frame 6 and the limiting sleeve 7. At the same time, the end of the second insertion rod 39 passes through the positioning fixture 4 and extends into the positioning groove 5. The second insertion rod 39 positions the positioning fixture 4 to prevent the positioning fixture 4 from falling out of the mounting groove 3. When it is necessary to insert the end of the motor housing 10 into the positioning groove 5, the roller 12 located below the movable plate 36 contacts the inner side of the second arc plate 42. The second arc plate 42 is driven to move down by the second hydraulic push rod 43. The compression spring 40 pushes the shielding seat 37 and the movable plate 36 to slide relative to the clearance hole 38, so that the roller 12 located below the movable plate 36 moves down synchronously with the second arc plate 42. The movable plate 36 and the shielding seat 37 drive the corresponding second insertion rod 39 to move down synchronously. The end of the second insertion rod 39 is no longer located in the positioning groove 5. The operator can then insert the end of the motor housing 10 into the positioning groove 5, aligning the mounting hole on the motor housing 10 with the second insert rod 39. At this time, the telescopic end of the second hydraulic push rod 43 pushes the second arc plate 42 upward to its initial position. The second arc plate 42 and the first arc plate 41 then form a complete limiting sleeve 7. The end of the second insert rod 39 is inserted into the mounting hole on the motor housing 10. By positioning the motor housing 10 using several second insert rods 39, the motor housing 10 is prevented from dislodging from the positioning groove 5, thus completing the assembly between the motor housing 10 and the positioning fixture 4.

[0042] When it is necessary to remove the positioning fixture 4 from the mounting slot 3, similarly, the second hydraulic push rod 43 simply drives the second arc plate 42 to move down again, causing the second insert rod 39 to disengage from the positioning fixture 4, thus releasing the restriction on the position of the positioning fixture 4. The operator can then drive the positioning fixture 4 to translate relative to the mounting slot 3 and the rotating seat 2, allowing the positioning fixture 4 to be pulled out of the mounting slot 3. When the rotating seat 2 rotates, the rotating seat 2 drives several rollers 12 to roll sequentially on the inner sides of the first arc plate 41 and the second arc plate 42. The rollers 12 on the rotating support structure support the rotating seat 2, preventing the rotating seat 2 from rotating and wobbling relative to the rotating shell 8. The rollers 12 on the positioning mechanism support the movable plate 36. The end of the second insert rod 39 is always located in the mounting hole on the motor housing 10, ensuring that the motor housing 10 is fixed relative to the positioning fixture 4 and the rotating seat 2. Thus, the integrated cooperation of dynamic support, quick loading and unloading, and reliable positioning is achieved.

[0043] Example 4, based on Example 1, is... Figure 1 and Figure 3 The drive mechanism includes a mounting bracket 44 fixedly mounted on the top of the operating table 1. An adjusting seat 45 is slidably mounted on the mounting bracket 44. A second servo motor 47 is fixedly connected to the mounting bracket 44. A second lead screw 46 is fixedly connected to the output end of the second servo motor 47. The second lead screw 46 passes through the adjusting seat 45 and is threadedly engaged with the adjusting seat 45. A tool holder 48 is slidably provided below the adjusting seat 45. A turning tool 9 is fixedly connected to the tool holder 48. A third servo motor 49 is fixedly connected to the bottom of the adjusting seat 45. A third lead screw 50 is fixedly connected to the output end of the third servo motor 49. The third lead screw 50 passes through the tool holder 48 and is threadedly engaged with the tool holder 48.

[0044] The second servo motor 47 drives the second lead screw 46 to rotate, and the second lead screw 46 drives the adjusting seat 45 and the tool holder 48 to slide relative to the mounting bracket 44, so that the tool holder 48 and the turning tool 9 can slide synchronously, thereby moving the turning tool 9 in the avoidance direction to avoid the disassembly and assembly of the motor housing 10. When turning is required, the second servo motor 47 drives the second lead screw 46 to rotate in the opposite direction, so that the turning tool 9 moves to the preset turning position; then, the third servo motor 49 drives the third lead screw 50 to rotate, and the third lead screw 50 drives the tool holder 48 and the turning tool 9 to slide relative to the adjusting seat 45, so that the turning tool 9 moves in the feed direction to perform turning.
