Detailed Implementation

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and by way of embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously.

For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0019] according to Figures 1-23As shown, an automated multi-process machining system for gearbox housings includes an automated housing conveyor and an automated housing transfer mechanism. The automated housing conveyor is positioned on the ground between a conventional machine tool and a CNC machining center, and is used to automatically convey gearbox housings 1 to be processed to each group of roughing and finishing processes. The automated housing transfer mechanism is positioned on the ground and above the automated housing conveyor, so as to automatically load the gearbox housings 1 conveyed by the automated housing conveyor onto the conventional machine tool. After roughing is completed on the conventional machine tool, the housings are automatically transferred to the CNC machining center for finishing. After finishing is completed, the gearbox housings 1 are transferred from the CNC machining center back to the automated housing conveyor for the next process. Furthermore, the automated housing transfer mechanism can move longitudinally along the automated housing conveyor to transfer multiple gearbox housings 1 conveyed by the automated housing conveyor to multiple groups of roughing and finishing processes.

[0020] It should be noted that each set of roughing and finishing processes consists of a conventional machine tool and a CNC machining center. The gearbox housing 1 is first roughed on the conventional machine tool, and then transferred to the CNC machining center for finishing, which constitutes one roughing and finishing process. Multiple sets of roughing and finishing processes are arranged longitudinally along the housing automatic conveyor. The conventional machine tool for each set of roughing and finishing processes is located on one side of the housing automatic conveyor, and the CNC machining center for each set of roughing and finishing processes is located on the other side. Furthermore, the conventional machine tool and CNC machining center for each set of roughing and finishing processes are symmetrically distributed on both sides of the housing automatic conveyor, and their loading directions are opposite. The multiple sets of roughing and finishing processes are evenly distributed longitudinally along the housing automatic conveyor, allowing the housing automatic transfer mechanism to simultaneously and automatically transfer the gearbox housing 1 to be processed for multiple sets of roughing and finishing processes.

[0021] The automatic housing conveying component includes a conveyor 2, which is installed on the ground between the conventional machine tools and CNC machining centers of the multiple sets of roughing and finishing processes. The conveyor 2 is used to transport multiple gearbox housings 1 one by one to the multiple sets of roughing and finishing processes, so that the automatic housing transfer component can grab and transfer them to the conventional machine tools, and from the conventional machine tools to the CNC machining centers. Then, the CNC machining centers transfer the finished gearbox housings 1 to the automatic housing transfer component, thereby improving the efficiency of the automatic transfer of gearbox housings 1 through multiple processes.

[0022] The automatic transfer component of the housing includes a transfer support component, a longitudinal sliding lifting component, a transverse transfer component, and a transfer clamping component. The transfer support component is disposed on the ground and is located above the conveyor 2. The longitudinal sliding lifting component is slidably disposed on the transfer support component. The transverse transfer component is disposed on the longitudinal sliding lifting component. The transfer clamping component is disposed on the transverse transfer component.

[0023] The transfer support includes a transverse support frame 3 and a longitudinal slide rail 4. The transverse support frame 3 spans the conveyor 2 and is positioned on the ground. The longitudinal slide rail 4 is mounted on the transverse support frame 3 and is located above the conveyor 2, with its longitudinal direction parallel to the longitudinal direction of the conveyor 2. The transverse support frame 3 is generally gantry-shaped. Its two support legs cross the conveyor 2 and are fixed to the ground, with the distance between the two support legs greater than the distance between the conventional machine tool and the CNC machining center within a set of roughing and finishing processes. Furthermore, multiple transverse support frames 3 are provided, evenly distributed along the longitudinal direction of the conveyor 2. Alternatively, the distance between two adjacent transverse support frames 3 satisfies the requirements of at least one set of conventional machine tool and CNC machining center for the roughing and finishing processes. That is, at least one conventional machine tool is positioned between two adjacent transverse support frames 3 on one side of the conveyor 2, and at least one CNC machining center is positioned between two adjacent transverse support frames 3 on the other side of the conveyor 2. The longitudinal slide rail 4 is horizontally fixedly mounted on the plurality of transverse support frames 3, providing sliding support for the longitudinal sliding lifting component. Furthermore, the longitudinal slide rail 4 is in the shape of a rectangular groove, with one groove wall of the longitudinal slide rail 4 horizontally fixedly mounted on the plurality of transverse support frames 3. Two longitudinal slide rails 4 are arranged parallel and symmetrically along a transverse interval, improving the stability of the longitudinal sliding lifting component during sliding.

[0024] The longitudinal sliding lifting component includes a longitudinal sliding component and a lifting component. The longitudinal sliding component is slidably mounted on the flow support component, and the lifting component is mounted on the longitudinal sliding component. The longitudinal sliding component includes a longitudinal support sliding component and a longitudinal sliding power component. The longitudinal support sliding component is slidably mounted on the flow support component, and the longitudinal sliding power component is mounted on the longitudinal support sliding component. The longitudinal support sliding component includes a longitudinal sliding seat 5, a longitudinal sliding plate 6, and a longitudinal pulley 7. The longitudinal sliding plate 6 is mounted on the longitudinal sliding seat 5, and the longitudinal pulley 7 is mounted on the longitudinal sliding plate 6, and the longitudinal pulley 7 is rotatably connected to the longitudinal slide rail 4. Four longitudinal sliding plates 6 are symmetrically distributed on the four sides of the top surface of the longitudinal sliding seat 5. One end of the shaft of the longitudinal pulley 7 is fixedly mounted on the longitudinal sliding plate 6, and the side of the longitudinal pulley 7 is rolledly connected to the groove wall on the other side of the longitudinal slide rail 4. Eight longitudinal pulleys 7 are evenly distributed on the four longitudinal sliding plates 6, and two longitudinal pulleys 7 on the same longitudinal sliding plate 6 are rolledly clamped on both sides of the groove wall on the other side of the longitudinal slide rail 4, thereby improving the sliding stability of the longitudinal sliding seat 5 on the longitudinal slide rail 4.

[0025] The longitudinal sliding power component includes a first motor, a first transmission wheel, and a rack. The first motor is fixedly mounted on the longitudinal sliding seat 5, the first transmission wheel is fixedly mounted on the shaft of the first motor, and the rack is fixedly mounted on the longitudinal slide rail 4, meshing with the first transmission wheel. Furthermore, the rack and the longitudinal slide rail 4 have the same length. When the first motor drives the first transmission wheel to rotate, the rack exerts a counterforce on the first transmission wheel, causing the longitudinal sliding seat 5 to slide longitudinally along the longitudinal slide rail 4. Alternatively, the first transmission wheel can be a gear.

[0026] The lifting component includes a lifting transmission component and a lifting power component. Both the lifting transmission component and the lifting power component are mounted on the longitudinal support sliding component, and the lifting power component is drive-connected to the lifting transmission component. The lifting transmission component includes a lifting transmission rod 8, a lifting transmission seat 9, and a guide rod 10. One end of the lifting transmission rod 8 slides downward vertically through the center of the longitudinal sliding seat 5, and the other end of the lifting transmission rod 8 is drive-connected to the lifting power component. The lifting transmission seat 9 is generally rectangular in shape, and the center of the outer side of the bottom of the lifting transmission seat 9 is horizontally fixed to one end of the lifting transmission rod 8. One end of the guide rod 10 slides through the guide hole on the longitudinal sliding seat 5 and is then fixed to the lifting transmission seat 9. The four guide rods 10 are evenly distributed on the lifting transmission seat 9 to improve the stability of the lifting transmission seat 9 during the lifting process pulled by the lifting transmission rod 8.

[0027] The lifting power component includes a third motor 44 and a lifting transmission wheel. The third motor 44 is fixedly mounted on the longitudinal sliding seat 5, and the lifting transmission wheel is mounted on the rotating shaft of the third motor 44. The teeth of the lifting transmission wheel mesh with the teeth on the side wall of the lifting transmission rod 8, thereby driving the lifting transmission rod 8 to rise and fall. Furthermore, a protective sleeve is fitted at the meshing point between the lifting transmission wheel and the lifting transmission rod 8. The lifting transmission wheel is a gear.

[0028] The transverse transfer component includes a transverse conveyor seat 11, a first transverse extension, a second transverse extension 12, and a transverse transmission component. The transverse conveyor seat 11 is disposed on the lifting transmission component. The first transverse extension and the second transverse extension 12 are slidably disposed at opposite ends of the transverse conveyor seat 11. The transverse transmission component is disposed on the transverse conveyor seat 11. Further, the transverse conveyor seat 11 is rectangular in shape, and its length is less than the horizontal transverse distance between the conventional machine tool and the CNC machining center in each group of roughing and finishing processes. One wall of the transverse conveyor seat 11 is horizontally fixed on the lifting transmission seat 9. Two sets of the transverse transfer component are provided, and the two sets are symmetrically distributed parallel to each other on the lifting transmission component.

[0029] The first lateral extension includes a lateral extension frame 13 and a linear actuator 14. The lateral extension frame 13 is rectangular and is axially slidably fitted into one end of the lateral conveyor seat 11. Further, the length of the lateral extension frame 13 is less than half the length of the lateral conveyor seat 11. The bottom end of the linear actuator 14 is horizontally fixed to one end of the groove wall on one side of the lateral conveyor seat 11, and the top end of the linear actuator 14 is fixedly connected to one end of the lateral extension frame 13 via a relay transmission block 15. When the linear actuator 14 extends, it drives the lateral extension frame 13 to extend towards the conventional machine tool, thereby transferring the transfer clamping member holding the gearbox housing 1 to be rough-machined to the worktable of the conventional machine tool, and finally transferring the gearbox housing 1 to be rough-machined onto the worktable of the conventional machine tool. Alternatively, the linear actuator 14 can be an electric, hydraulic, or pneumatic automatic jacking device.

[0030] The second lateral extension 12 has the same structure as the first lateral extension. The second lateral extension 12 is slidably disposed on the other end of the lateral conveying seat 11, and the second lateral extension 12 is symmetrically distributed with the first lateral extension.

[0031] After the rough machining of the gearbox housing 1 is completed, the transverse transmission member transfers the transfer clamping member to the rightmost side of the second transverse extension member 12. At this time, when the linear actuator 14 of the second transverse extension member 12 extends, it will drive the transverse extension frame 13 of the second transverse extension member 12 to extend towards the CNC machining center, thereby transferring the transfer clamping member holding the gearbox housing 1 to be finished from the ordinary machine tool to the CNC machining center, and finally transferring the gearbox housing 1 to be finished onto the worktable of the CNC machining center.

[0032] The transverse transmission component includes a transverse transmission power component and a transverse transmission extension tube 16. The transverse transmission power component is mounted on the transverse conveyor seat 11, and the transverse transmission extension tube 16 is axially slidingly and circumferentially locked to the transverse transmission power component. The transverse transmission power component includes a second motor 17, a second transmission wheel 18, a relay transmission wheel 19, a transverse transmission rod 20, and a third transmission wheel 21. The second motor 17 is fixedly mounted on the groove wall of the other side of the transverse conveyor seat 11. The second transmission wheel 18 is fixedly mounted on the rotating shaft of the second motor 17. The relay transmission wheel 19 is rotatably fitted into a relay through hole on the groove wall of the other side of the transverse conveyor seat 11 via its rotating shaft. The upper part of the relay transmission wheel 19 meshes with the second transmission wheel 18, while the lower part of the relay transmission wheel 19 penetrates into the groove of the transverse conveyor seat 11. The relay through hole is located at the axial center of the transverse conveyor seat 11. The transverse transmission rod 20 is disposed within the groove of the transverse conveying seat 11 via the transverse transmission extension tube 16. The third transmission wheel 21 is fixedly fitted at the axial midpoint of the transverse transmission rod 20, and the third transmission wheel 21 engages with the intermediate transmission wheel 19 below for transmission. Simultaneously, the transverse transmission rod 20 rotates circumferentially and is axially locked within the transverse conveying groove via the third transmission wheel 21 and the intermediate transmission wheel 19. Further, the outer diameter of the third transmission wheel 21 is smaller than the outer diameter of the transverse transmission extension tube 16. Alternatively, the second transmission wheel 18, the intermediate transmission wheel 19, and the third transmission wheel 21 can all be gears or friction transmission wheels.

[0033] The outer wall of the transverse transmission extension tube 16 is provided with external threads. One end of the transverse transmission extension tube 16 is axially sliding and circumferentially locked onto one end of the transverse transmission rod 20, and the other end of the transverse transmission extension tube 16 is circumferentially rotating and axially locked into a rotating groove 22 on one end face of the transverse extension frame 13. The rotating groove 22 is fixedly provided on one end face of the transverse extension frame 13. Further, there are two transverse transmission extension tubes 16, which are successively fitted onto both ends of the transverse transmission rod 20. The two transverse transmission extension tubes 16 are connected to the transverse transmission rod 20 and the transverse extension frame 13 in the same way, and one end of each of the two transverse transmission extension tubes 16 can be in contact with both end faces of the third transmission wheel 21. This is used to engage and push the transfer clamping member towards one end of the transverse extension frame 13, and to transfer the transfer clamping member between the transverse extension frame 13 of the first transverse extension member and the transverse extension frame 13 of the second transverse extension member 12.

[0034] The transfer clamping component includes a clamping support, a circumferential clamping component, and a clamping power component. The clamping support is disposed on the transverse transfer component, and both the circumferential clamping component and the clamping power component are disposed on the clamping support. The clamping support includes a transfer support and a circumferential clamping seat 23. The transfer support is disposed on the transverse transfer component, and the circumferential clamping seat 23 is disposed on the transfer support.

[0035] The transfer support includes a transfer transmission seat 24 and a clamping support rod 25. The transfer transmission seat 24 is slidably disposed on the first lateral extension and the second lateral extension 12, and one end of the clamping support rod 25 is disposed on the transfer transmission seat 24. The transfer transmission seat 24 is generally rectangular in shape. The bottom surface of the transfer transmission seat 24 is slidably disposed on a groove wall of the lateral extension frame of the first lateral extension and a groove wall of the lateral extension frame of the second lateral extension 12. Furthermore, the internal thread on the top surface of the transfer transmission seat 24 can simultaneously engage with the external threads below the inner ends of the two lateral transmission extension tubes 16. Further, the internal thread on the top surface of the transfer transmission seat 24 is located on the transmission arc surface of the top surface of the transfer transmission seat 24, and the transmission arc is arc-shaped. The circumferential angle of the transmission arc is no greater than 180 degrees, so that the internal thread can mesh upward with the lower side of the external thread. Since the outer diameter of the third transmission wheel 21 is smaller than the outer diameter of the transverse transmission extension tube 16, the internal thread will not contact the third transmission wheel 21.

[0036] Two sets of the transfer support components are provided, and the two sets of transfer support components correspond one-to-one with the two sets of transverse transfer components to support the circumferential clamping seat 23 from both sides, thereby improving the stability of the transfer process.

[0037] The circumferential clamping seat 23 includes an outer support seat 26, an inner support seat 27, and a connecting seat 28. The sidewall of the outer support seat 26 is disposed on the other end of the clamping support rod 25. Both the outer support seat 26 and the inner support seat 27 are cylindrical, with the outer diameter of the inner support seat 27 being smaller than the inner diameter of the outer support seat 26. The connecting seat 28 is an annular plate, with its outer ring edge fixedly disposed on the top port of the outer support seat 26 and its inner ring edge fixedly disposed on the top port of the inner support seat 27, such that the axis of the outer support seat 26 coincides with the axis of the inner support seat 27. The inner diameter of the inner support seat 27 is larger than the diameter of the gearbox housing 1 to be processed.

[0038] The circumferential clamping member includes an upper clamping member and a lower clamping member 43. Both the upper clamping member and the lower clamping member 43 are disposed on the circumferential clamping seat 23, and the clamping power member simultaneously transmits power to the upper clamping member and the lower clamping member 43.

One end of the outer guide tube 29 passes through the side wall of the outer support seat 26, and the axis of the outer guide tube 29 coincides with the radial line of the outer support seat 26. One end of the inner guide tube 30 passes through the side wall of the inner support seat 27, and the axis of the inner guide tube 30 coincides with the axis of the outer guide tube 29. One end of the radial sliding clamping rod 31 slides axially and is circumferentially locked, passing through the outer guide tube 29 and the inner guide tube 30 successively, extending into the inner support seat 27 tube. The radial clamping transmission tube 32 is fitted onto the radial sliding clamping rod 31, and the internal thread on the inner wall of the radial clamping transmission tube 32 engages with the external thread on the outer wall of the radial sliding clamping rod 31. A first thrust ball bearing 33 is provided between the radial clamping transmission tube 32 and the outer guide tube 29, and a second thrust ball bearing 34 is provided between the radial clamping transmission tube 32 and the inner guide tube 30. When the radial clamping transmission tube 32 is driven to rotate forward by the clamping force adjustment component, it will drive the radial sliding clamping rod 31 to move radially inward along the circumferential clamping seat 23, clamping the side wall of the gearbox housing 1 to be processed radially. Furthermore, an anti-slip pad 35 is provided at one end of the radial sliding clamping rod 31 to improve the clamping stability of the gearbox housing 1.

[0040] The clamping force adjusting component includes a fourth transmission wheel 36, a spring 37, and a circumferential transmission tongue 38. The fourth transmission wheel 36 is circumferentially rotated and axially locked onto the radial clamping transmission tube 32. The spring 37 is embedded in the bottom of a clamping hole on the inner wall of the fourth transmission wheel 36, with the axis of the clamping hole coinciding with the radial line of the fourth transmission wheel 36. Furthermore, multiple clamping holes are circumferentially distributed around the fourth transmission wheel 36, and each clamping hole contains a spring 37. The bottom end of the circumferential transmission tongue 38 axially slides and compresses the spring 37 embedded in the opening of the clamping hole. The top end of the circumferential transmission tongue 38 is pushed by the spring 37 and inserted into a clamping groove on the outer wall of the radial clamping transmission tube 32. Multiple clamping grooves are circumferentially distributed around the radial clamping transmission tube 32. Optionally, the number of clamping grooves is greater than the number of circumferential transmission tongues 38. Each of the multiple circumferential transmission tongues 38 corresponds one-to-one with a single clamping hole. Furthermore, the tip of the circumferential transmission tongue 38 is hemispherical, and the clamping groove is arc-shaped. Alternatively, the fourth transmission wheel 36 is a gear.

[0041] When the fourth transmission wheel 36 is driven to rotate in the forward direction, it will drive the radial clamping transmission tube 32 to rotate in the forward direction through the circumferential transmission tongue 38. The forward-rotating radial clamping transmission tube 32 will drive one end of the radial sliding clamping rod 31 to clamp the gearbox housing 1. When the radial clamping force of one end of the radial sliding clamping rod 31 on the gearbox housing 1 exceeds a predetermined value, the squeezing force of the clamping groove on the tip of the circumferential transmission tongue 38 will be greater than the pushing force of the spring 37, thereby causing the tip of the circumferential transmission tongue 38 to slide out of the clamping groove, preventing the radial sliding clamping rod 31 from causing clamping damage to the gearbox housing 1.

[0042] Eight sets of upper clamping members are provided, which are evenly distributed around the circumferential clamping seat 23, and are positioned near one end of the circumferential clamping seat 23. After the circumferential clamping seat 23 is fitted over the gearbox housing 1 to be processed, the eight sets of upper clamping members are used to circumferentially clamp the upper part of the gearbox housing 1.

[0043] The lower clamping member 43 and the upper clamping member have the same structure, and the connection method between the lower clamping member 43 and the circumferential clamping seat 23 is the same as that between the upper clamping member and the circumferential clamping seat 23. Furthermore, eight sets of lower clamping members 43 are sequentially arranged directly below eight sets of upper clamping members. The eight sets of lower clamping members 43 are used to circumferentially clamp the lower part of the gearbox housing 1, and by cooperating with the eight sets of upper clamping members, further improve the clamping firmness of the gearbox housing 1.

[0044] The clamping power component includes a clamping transmission component and a circumferential clamping power component, both of which are mounted on the circumferential clamping seat 23. The clamping transmission component includes a transmission guide seat and a clamping transmission block 39. The two sides of the transmission guide seat are respectively fixed to the inner sidewall of the outer support seat 26 and the outer sidewall of the inner support seat 27, and the longitudinal direction of the transmission guide seat is parallel to the axis of the circumferential clamping seat 23. The clamping transmission block 39 is rectangular in shape and is axially slidably fitted into a guide groove on the transmission guide seat. The rack teeth on one side of the clamping transmission block 39 mesh with the gear teeth on the fourth transmission wheel 36, and simultaneously, the rack teeth on one side of the clamping transmission block 39 also mesh with the fourth transmission wheel 36 of the lower clamping member 43. When the clamping transmission block 39 moves longitudinally on the transmission guide seat, it will simultaneously drive the fourth transmission wheel 36 of the upper clamping member and the fourth transmission wheel 36 of the lower clamping member 43 to rotate in the forward direction through the rack teeth, thereby simultaneously driving the radial sliding clamping rod 31 of the upper clamping member and the radial sliding clamping rod 31 of the lower clamping member 43 to clamp the gearbox housing 1.

[0045] Furthermore, eight sets of clamping transmission components are provided, and the eight sets of clamping transmission components are respectively provided in correspondence with the eight sets of upper clamping components and the eight sets of lower clamping components 43.

[0046] The circumferential clamping power component includes a circumferential transmission tube 40, a fourth motor 41, and a fifth transmission wheel 42. One end of the circumferential transmission tube 40 is rotatably mounted on the connecting seat 28, and the internal thread on the inner wall of the circumferential transmission tube 40 engages with the threaded groove on the other side of the clamping transmission block 39. Furthermore, the internal thread on the inner wall of the circumferential transmission tube 40 simultaneously engages with the threaded grooves on the other side of all eight clamping transmission blocks 39. The fourth motor 41 is fixedly mounted on the circumferential clamping seat 23, and the fifth transmission wheel 42 is fixedly mounted on the rotating shaft of the fourth motor 41, and the fifth transmission wheel 42 meshes with the gear teeth on the outer wall of the circumferential transmission tube 40. When the fourth motor 41 drives the fifth transmission wheel 42 to rotate in the forward direction, the fifth transmission wheel 42 will drive the circumferential transmission tube 40 to rotate in the forward direction. The rotating circumferential transmission tube 40 drives the clamping transmission block 39 to move longitudinally through the threaded groove, and then the clamping transmission block 39 drives the fourth transmission wheel 36 to rotate in the forward direction. Since the internal thread on the inner wall of the circumferential transmission tube 40 simultaneously engages with the threaded groove on the other side of the eight clamping transmission blocks 39, when the circumferential transmission tube 40 is rotated in the forward direction, it can simultaneously drive the eight sets of upper clamping members and the eight sets of lower clamping members 43 to clamp the gearbox housing 1.

[0047] It should be noted that, since the gearbox housing 1 to be processed has an irregular circumferential shape, some of the eight sets of upper clamping members first abut against the gearbox housing 1 radially and reach a predetermined clamping force (the eight sets of upper clamping members do not abut against the gearbox housing 1 simultaneously). Then, they slide out of the clamping groove via the circumferential transmission tongue 38 (and slide into the adjacent clamping groove), without further increasing the clamping force, to prevent damage to the gearbox housing 1. When the other sets of upper clamping members are not abutting or the clamping force has not reached the predetermined clamping force, they continue to move radially towards the gearbox housing 1 to clamp it. Once the clamping force of all eight sets of upper clamping members and the eight sets of lower clamping members 43 on the gearbox housing 1 reaches the predetermined clamping force, the clamping operation of the gearbox housing 1 can be completed.

[0048] The method of using the automated multi-process machining system for the gearbox housing is as follows: 1) The conveyor 2 transports multiple gearbox housings 1 to be processed to multiple sets of roughing and finishing processes; 2) Activate the longitudinal sliding power component to move the circumferential clamping seat 23 to directly above the gearbox housing 1 and then lower it so that the circumferential clamping seat 23 is fitted over the gearbox housing 1; 3) Activate the circumferential clamping power component to make the circumferential transmission tube 40 rotate in the forward direction, and then drive the radial sliding clamping rod 31 to move radially inward through the clamping transmission block 39, the fourth transmission wheel 36 and the radial clamping transmission tube 32, thereby circumferentially clamping the gearbox housing 1; 4) Activate the lifting component to raise the circumferential clamping seat 23 holding the gearbox housing 1 to a predetermined height; 5) Start the transverse transmission power component to drive the two transverse transmission extension tubes 16 to rotate in the forward direction at the same time, thereby causing the flow transmission seat 24 to slide horizontally into the transverse extension frame 13 and continue to slide to the limit at one end of the transverse extension frame 13 (at this time, the gearbox housing 1 is transferred to the side of the ordinary machine tool). 6) Extend the linear actuator 14 so that one end of the transverse extension frame 13 slides out from the groove at one end of the transverse conveyor seat 11 to directly above the worktable of the ordinary machine tool. 7) Activate the lifting component to drive the circumferential clamping seat 23 holding the gearbox housing 1 to descend, so that the gearbox housing 1 is released and transferred to the worktable of the ordinary machine tool, and then the circumferential clamping seat 23 is reset; 8) After the ordinary machine tool has completed the rough machining of the gearbox housing 1, the circumferential clamping seat 23 is fitted over the gearbox housing 1 to complete the clamping of the gearbox housing 1; 9) Shorten the linear actuator 14 so that the lateral extension frame 13 slides into the groove at one end of the lateral conveyor seat 11; 10) Start the transverse transmission power component to drive the two transverse transmission extension tubes 16 to rotate in opposite directions at the same time, thereby causing the flow transmission seat 24 to slide horizontally from one end of the transverse extension frame 13 into one end of the transverse extension frame of the second transverse extension component 12 to the limit (at this time, the gearbox housing 1 is transferred to the side of the CNC machining center machine tool). 11) Extend the linear actuator of the second lateral extension 12 so that one end of the lateral extension frame of the second lateral extension 12 slides out from the groove at the other end of the lateral conveyor seat 11 to directly above the worktable of the CNC machining center. 12) Activate the lifting component to drive the circumferential clamping seat 23 holding the gearbox housing 1 to descend, so that the gearbox housing 1 is released and transferred to the worktable of the CNC machining center, and then the circumferential clamping seat 23 is reset; 13) After the CNC machining center finishes the gearbox housing 1, the circumferential clamping seat 23 is placed on the outside of the gearbox housing 1 and clamps the gearbox housing 1. Then, the finished gearbox housing 1 is transferred to the conveyor 2 to continue to the next process.

[0049] As an option, the number of ordinary machine tools and CNC machining centers on both sides of the conveyor 2 can be different, and can be reasonably matched according to the difference in roughing and finishing times. Alternatively, the gearbox housing 1 processed by the ordinary machine tools in one set of roughing and finishing processes can also be transferred to the CNC machining centers in another set of roughing and finishing processes for finishing, according to the maintenance needs of each machine tool.
