Description

Technical Field

[0001] The present application relates to the technical field of integrated drilling and grinding devices, and in particular to an integrated drilling and grinding device for processing a reducer housing. Background Art

[0002] A reducer is a mechanical device used for speed reduction transmission between the prime mover and the working machine. It is widely used in various industrial equipment and mechanical systems. For example, a common planetary gear reducer includes upper and lower housings fixedly connected by bolts and nuts, as well as components such as a gear structure located inside the housing.

[0003] In order to ensure the connection accuracy and sealing performance of the shell, when processing the shell, the principle of first face and then hole is usually followed. The end face and the joint surface of the shell are milled first, and then the shell is clamped and fixed with the end face as the positioning reference, and the connection holes for bolts and nuts are processed on the joint surface. Usually, a drilling machine is used to drill holes in the shell to achieve rough processing of the connection holes. After the drilling is completed, the technicians transport the shell to the grinder for fixation, and then grind the connection holes to achieve micro-grinding of the inner wall of the connection hole, thereby expanding the hole and grinding the burrs generated during drilling to improve the accuracy of the connection hole.

[0004] Regarding the above-mentioned related technologies, when the drilling and grinding processes are carried out in steps, after drilling, the technicians need to transport the shell to the grinder and clamp and fix the shell. The secondary clamping may easily cause position deviation and introduce new relative errors, thereby affecting the shape accuracy of the connecting hole and aggravating the wear of the grinding tool. At the same time, when the shell is clamped only with the end face as the reference, it is not easy for the technicians to position the shell and keep the center circle formed by the multiple connecting holes processed coaxial with the bearing hole on the shell, affecting the connection strength and sealing performance of the upper shell and the lower shell, so it needs to be improved. Summary of the Invention

[0005] In order to improve the housing clamping and positioning accuracy, reduce the precision error caused by secondary clamping and positioning, and improve the accuracy and processing efficiency of the connecting holes, the present application provides an integrated drilling and polishing device for processing the reducer housing.

[0006] The present application provides an integrated drilling and grinding device for processing a reducer housing, which adopts the following technical solutions: A drilling and grinding integrated device for processing a reducer housing comprises a frame and a mounting plate that is lifted and lowered on the frame, a rotating plate that is coaxially rotatably provided on the mounting plate, a processing assembly that processes connecting holes in the housing is provided on the rotating plate, the housing is placed on the frame and is located below the processing assembly, a first power member that drives the mounting plate to lift and lower, a rotating assembly that drives the rotating plate to rotate, and a positioning assembly that positions and fixes the housing are provided on the frame, and a locking assembly that locks the rotating plate and the mounting plate is also provided on the frame; The machining assembly includes a plurality of switching blocks rotatably disposed at the bottom of the rotating disk, the plurality of switching blocks being evenly spaced along the circumference of the rotating disk, a drill bit and an internal grinding rod being rotatably disposed on the switching blocks, the drill bit and the internal grinding rod being spaced around the rotation axis of the switching blocks, one of the drill bit and the internal grinding rod being corresponding to the housing, and a transmission member for driving the drill bit and the internal grinding rod to rotate being disposed on the frame; The rotating assembly includes a driven gear coaxially arranged on the rotating shaft of the switching block, an inner gear ring coaxially arranged on the mounting plate, multiple driven gears are meshed with the inner gear ring, and a limiting member for limiting the switching block and a driving member for driving the inner gear ring to rotate are provided on the frame; The positioning assembly comprises a positioning wheel coaxially arranged at the bottom end of the inner grinding rod, the diameter of the positioning wheel is smaller than the diameter of the inner grinding rod, and the outer peripheral wall of the positioning wheel is movably pressed against the outer peripheral wall of the shell.

[0007] By adopting the above technical solution, when it is necessary to process the connecting hole on the shell, the technician places the shell on the frame. At this time, the drill bit, internal grinding rod and positioning wheel are all located above the shell, which is convenient for the technician to place the shell. At the same time, the drill bit corresponds to the shell, and the locking assembly locks the rotating disk and the mounting disk, so that the rotating disk and the mounting disk remain relatively fixed. This is the initial state.

[0008] Then the technician starts the equipment. At this time, the first power part works and drives the mounting plate to descend, drives the rotating plate and the switching block to descend, thereby driving the positioning wheel to descend until the bottom end of the positioning wheel is located below the joint surface of the shell. At this time, the drill bit and the internal grinding rod are still located above the shell, and are in the positioning state.

[0009] Then the driving part works and drives the inner ring gear to rotate. Since the rotating disk and the mounting disk remain relatively fixed at this time, the inner ring gear drives the driven gear and the switching block to rotate, thereby causing the positioning wheel to rotate around the rotation axis of the switching block until the outer peripheral wall of the positioning wheel is tightly pressed against the outer peripheral wall of the shell. At this time, multiple positioning wheels are pressed against the shell at the same time, so that the shell and the rotating disk remain coaxial, thereby realizing the positioning of the shell, and then the positioning assembly fixes the shell, thereby improving the clamping accuracy of the shell.

[0010] At the same time, since the positioning wheel is coaxial with the internal grinding rod, the positioning wheel, drill bit and internal grinding rod all move based on the same mechanical coordinate system during positioning, drilling and grinding, reducing the position error between the positioning wheel, drill bit and internal grinding rod, and improving the position accuracy of the drill bit / internal grinding rod during drilling / grinding.

[0011] After the positioning and fixing are completed, the first power member drives the mounting plate to rise, and then the driving member drives the inner gear ring to rotate, so that the mounting plate, the drill bit and the inner grinding rod move to the initial state, and then the first power member drives the mounting plate to descend, and at the same time the transmission member drives the drill bit to rotate to realize drilling of the shell.

[0012] After the drilling is completed, the first power member and the driving member work to move the mounting plate, the drill bit and the internal grinding rod to the initial state, and then the driving member drives the inner gear ring to rotate to realize the rotation of the switching block until the internal grinding rod corresponds to the shell. At this time, the internal grinding rod and the connecting hole remain coaxial, and then the first power member drives the mounting plate to descend, and at the same time the transmission member drives the internal grinding wheel to rotate to realize the grinding of the connecting hole and improve the accuracy of the connecting hole.

[0013] Then the first power member and the driving member work to move the mounting disk, the drill bit and the inner circular grinding rod to the initial state, and then the first power member drives the mounting disk to rise. At this time, the locking assembly unlocks the rotating disk and the mounting disk, so that the rotating disk and the mounting disk keep rotating relative to each other, and then the driving member drives the inner ring gear to rotate. At this time, the limit member limits the switching block, so that the switching block is less likely to rotate than the rotating disk. At this time, the driven gear and the inner ring gear remain relatively fixed, so that the inner ring gear drives the rotating disk to rotate, and the drill bit and the inner circular grinding rod move to the processing position of the next connecting hole. Then the first power member drives the mounting disk down to the initial state and performs the next processing. By repeating the above steps, multiple high-density connecting holes can be quickly processed, thereby improving processing efficiency.

[0014] At the same time, the switching block is driven to rotate by the driving member, so that the drill bit and the internal grinding rod are selected to correspond to the housing, so that the internal grinding rod is not easy to contact with the housing during drilling, thereby reducing additional wear of the internal grinding rod and improving the service life of the internal grinding rod. At the same time, the drill bit is not easy to drop and extend into the polished connecting hole during grinding, thereby reducing the impact on the polished connecting hole and improving the accuracy of the connecting hole.

[0015] Through the above solution, during the drilling and grinding process, the precision error caused by secondary clamping and positioning is reduced, the precision and processing efficiency of the connecting holes are improved, and by setting up multiple drill bits and multiple internal grinding rods, the tangential force during the processing process is effectively balanced, the vibration and deflection of the drill bits or internal grinding rods are reduced, and the precision of the connecting holes is further improved.

[0016] Optionally, the transmission member includes a first drive gear coaxially arranged on the drill bit, and a second drive gear coaxially arranged on the internal grinding rod. The first drive gear and the second drive gear are both engaged with the driven gear, and a one-way bearing is provided at the connection between the driven gear and the switching block shaft.

[0017] By adopting the above technical solution, when the drill bit and the internal grinding rod are switched, the inner ring gear drives the driven gear to rotate. At this time, the one-way bearing is in a locked state, so that the driven gear drives the switching block to rotate, thereby causing the drill bit and the internal grinding rod to rotate around the rotation axis of the switching block until the internal grinding rod corresponds to the housing, thereby realizing the switching of the drill bit and the internal grinding rod.

[0018] When drilling / grinding, the inner gear ring drives the driven gear to reverse. At this time, the one-way bearing is in a free rotation state. At the same time, the limiting member limits the switching block, making it difficult for the switching block to reverse, so that the driven gear drives the first drive gear and the second drive gear to rotate, thereby realizing the rotation of multiple drill bits / multiple internal grinding rods. When the drill bits / internal grinding rods are idling, it is beneficial to throw off metal debris attached to the drill bits / internal grinding rods to achieve self-cleaning. At the same time, multiple drill bits drill holes or multiple internal grinding rods grind synchronously, further reducing the vibration and deflection of the drill bits or internal grinding rods, improving the accuracy of the connecting holes, and saving power sources.

[0019] Optionally, the limiting member includes a fixed ratchet coaxially arranged on the rotating shaft of the switching block, a movable ratchet is slidingly arranged in the rotating disk, the fixed ratchet and the movable ratchet are coaxially arranged, and the side walls of the fixed ratchet and the movable ratchet close to each other are movably engaged, a limiting structure for limiting the rotation of the movable ratchet is provided on the rotating disk, and an elastic member is provided on the rotating disk for pressing the movable ratchet against the fixed ratchet.

[0020] By adopting the above technical solution, when it is necessary to drive the switching block to rotate, due to the characteristics of the fixed ratchet and the movable ratchet, and the movable ratchet is slidably arranged in the rotating disk, the locking assembly locks the rotating disk and the mounting disk, so that the rotating disk and the mounting disk remain relatively fixed. When the inner ring gear rotates, it drives the switching block and the fixed ratchet to rotate. At this time, the movable ratchet overcomes the force of the elastic member and slides in the direction away from the fixed ratchet, so that the fixed ratchet and the movable ratchet can rotate relative to each other until the switching block rotates to the set position. At this time, the elastic member makes the movable ratchet press against the fixed ratchet. At the same time, due to the action of the limiting structure, the movable ratchet and the fixed ratchet are not easy to rotate, thereby realizing the rotation of the switching block.

[0021] When the drill bit / internal grinding rod needs to be driven to rotate, the locking assembly is in a locked state, so that the rotating disk and the mounting disk remain relatively fixed. When the inner ring gear drives the driven gear to reverse, at this time, due to the one-way gear set, the fixed ratchet and the limit ratchet are not easy to rotate relative to each other, so the switching block remains relatively fixed, so that when the drill bit / internal grinding rod is driven to rotate, the rotating disk and the switching block remain in a fixed state, thereby improving the stability of the drill bit / internal grinding rod and the accuracy of the connecting hole.

[0022] When the rotating disk needs to be driven to rotate, the locking assembly unlocks the rotating disk and the mounting disk, so that the rotating disk and the mounting disk keep rotating relative to each other. At the same time, the elastic member makes the movable ratchet press against the fixed ratchet, making the switching block less likely to rotate than the rotating disk. When the inner ring gear rotates, the inner ring gear and the driven gear remain relatively fixed. At this time, the inner ring gear, the driven gear and the rotating disk rotate synchronously, thereby realizing the rotation of the rotating disk.

[0023] Compared with achieving multiple steps through multiple power sources, which requires high coordination of the power sources and is not easy to arrange and install on the mounting plate, the above solution uses one power source to achieve the switching of the drill bit / internal circle grinding rod, the driving of the drill bit / internal circle magic head and the rotation of the rotating plate, thereby improving the stability and coordination of the equipment operation and improving the processing accuracy and efficiency of the connecting holes.

[0024] Optionally, the locking assembly includes a plug-in rod elastically slidably arranged in the rotating disk, one end of the plug-in rod movably protrudes from the outer wall of the rotating disk, a plurality of plug-in holes are opened on the mounting disk, and the plug-in holes are evenly spaced along the circumference direction of the mounting disk. The plug-in rod corresponds to one of the plurality of plug-in rods, the plug-in rod is movably inserted into the plug-in hole, and movably pressed against the inner wall of the plug-in hole, and a sliding adjustment member for driving the plug-in rod is provided on the rotating disk.

[0025] By adopting the above technical solution, when it is necessary to unlock the rotating disk and the mounting disk, the adjusting part drives the protruding end of the plug-in rod to slide in the direction away from the plug-in hole, so that the plug-in rod is separated from the plug-in hole, thereby unlocking the rotating disk and the mounting disk. At this time, the rotating disk can rotate relative to the mounting disk, which is convenient for subsequent driving of the rotating disk to rotate, thereby improving the processing efficiency of the connecting hole.

[0026] When the rotating disk and the mounting disk need to be locked, the plug-in rod slides into the plug-in hole under the elastic force. At this time, the plug-in rod and the inner wall of the plug-in hole are tightly pressed against each other, making it difficult for the rotating disk to rotate, thereby locking the rotating disk and the mounting disk, improving the stability of the rotating disk, and thus improving the stability of drilling / grinding.

[0027] Optionally, the adjusting member includes an adjusting block elastically slidingly arranged at the axis of the rotating disk, one end of the adjusting block movably protrudes from the top wall of the mounting disk, and the protruding end of the adjusting block movably presses against the side walls of the frame that are close to each other, and the end of the adjusting block close to the plug-in rod is inclined, and one end of the plug-in rod presses against the inclined side of the adjusting block.

[0028] By adopting the above technical solution, when it is necessary to unlock the rotating disk and the mounting disk, the first power member drives the mounting disk to rise, so that the side walls of the frame and the adjustment block that are close to each other are pressed against each other, and drives the adjustment block to slide down. At this time, the connecting rod is pressed against the inclined side of the adjustment block under the elastic force, and slides in the direction close to the adjustment block, so that the connecting rod is separated from the connecting slot, thereby achieving unlocking of the rotating disk and the mounting disk.

[0029] When the first power member drives the mounting plate to descend and separates the adjusting block from the frame, the adjusting block slides up under the elastic force, so that the inclined side of the adjusting block presses against the plug-in rod and drives the plug-in rod to slide into the plug-in slot, thereby locking the rotating plate and the mounting plate.

[0030] Through the above solution, the lifting and lowering of the installation disk and the locking and unlocking of the rotating disk are carried out synchronously, and the automatic adjustment of the locking of the rotating disk and the installation disk is realized, which improves the coordination and stability of the equipment operation and saves power sources.

[0031] Optionally, the driving member includes a rotating worm wheel coaxially arranged on the mounting plate, the rotating worm wheel is coaxially connected to the inner gear ring, a rotating worm is rotatably arranged on the mounting plate, the rotating worm is engaged with the rotating worm wheel, and a second power member driving the rotating worm to rotate is provided on the mounting plate.

[0032] By adopting the above technical solution, when it is necessary to drive the inner gear ring to rotate, the second power part works and drives the transmission worm to rotate, drives the transmission worm wheel to rotate, and thus drives the inner gear ring to rotate, thereby realizing the steps of drilling and grinding, switching the drill bit and the internal grinding rod, and adjusting the rotating disk. Moreover, due to the self-locking characteristics of the worm gear, and the meshing clearance between the transmission worm wheel and the transmission worm is not easy to change with time or vibration and other factors, the precise and stable control of the number of rotations of the inner gear ring is improved, thereby improving the processing accuracy.

[0033] The cam is fixedly mounted on the support frame, and the cam is located below the support frame, and the cam is provided with a locking block for locking the cam, so that the cam can be locked to the support frame when the cam is locked.

[0034] By adopting the above technical solution, when clamping and fixing the shell, the technician places the shell coaxially with the center tube on the frame. At this time, the end of the clamping block away from its own rotation axis is close to the outer wall of the center tube, so that the clamping block is not easy to hinder the placement of the shell, which is convenient for the technician to operate.

[0035] After the positioning is completed, the control part controls the center rod to slide, so that the center rod slides in the direction away from the rotating disk, the connecting rod moves in the direction close to the clamping block, and the end of the clamping block away from its own rotation axis moves in the direction away from the center tube until the clamping block rotates to a horizontal state. At this time, the side walls of the clamping block and the center tube that are close to each other are pressed against each other, and at the same time, the ear plate and the side walls of the clamping block that are close to each other are pressed against each other, and drive the clamping block and the center tube to slide in the direction away from the rotating disk until the bottom side of the clamping block presses against the step of the housing used to support the outer ring of the bearing, thereby fixing the housing, reducing manual operation steps, and improving processing efficiency.

[0036] When disassembling the shell, the control part controls the sliding of the center rod, causing the center rod to slide toward the rotating disk, and the tightening block to rotate to its initial position, making it easier for technicians to remove the shell. At the same time, the center tube slides toward the rotating disk under the elastic force, making it easier to fix it next time.

[0037] Optionally, the control component includes a displacement sensor arranged on the movable ratchet, and the frame is also provided with a third power component for driving the center rod to slide. The frame is also provided with a controller, and the displacement sensor, the first power component, the second power component and the third power component are all electrically connected to the controller.

[0038] By adopting the above technical solution, when the shell is positioned, under the action of the first power piece, the mounting plate is at the height of the positioning state, the second power piece works to realize the rotation of the switching block, and drives the positioning wheel to rotate around the rotation axis of the switching block. At this time, the fixed ratchet rotates, and the movable ratchet overcomes the force of the elastic piece and slides back and forth until the displacement sensor detects that the movable ratchet is no longer sliding. At this time, the displacement sensor transmits an electrical signal to the controller. If the first power causes the mounting plate to be at the height of the positioning state at this time, the controller causes the third power piece to work and drives the center rod to slide in the direction away from the rotating disk, thereby fixing the shell, and the shell fixing and shell positioning are automated to improve processing efficiency.

[0039] In summary, this application includes at least one of the following beneficial technical effects: 1. When machining the connecting hole, the second power piece is used to drive the inner gear ring to rotate. At this time, the one-way bearing is in a locked state, thereby driving the driven gear and the switching block to rotate, thereby switching the drill bit and the internal grinding tool. When drilling is switched to grinding, the steps of secondary clamping and positioning are reduced, and the coaxiality of the drill bit and the internal grinding rod is ensured during drilling and grinding, thereby improving the accuracy and machining efficiency of the connecting hole. When the second power piece is used to drive the inner gear ring to reverse, the one-way bearing is in a free rotation state, so that the inner gear ring drives the driven gear to rotate. At this time, the limiting piece is set to prevent the switching block from rotating easily, so that the driven gear stably drives the first drive gear and the second drive gear to rotate, thereby driving multiple drill bits and multiple internal grinding rods, thereby realizing synchronous drilling and synchronous grinding, thereby effectively balancing the tangential force during the machining process, reducing the vibration and deflection of the drill bit or internal grinding rod, and further improving the accuracy of the connecting hole; At the same time, compared with using multiple power sources to achieve multiple steps, which requires high coordination of the power sources and is not easy to arrange and install on the mounting plate, the above solution uses a single power source to achieve the switching of the drill bit / internal grinding rod and the driving of the drill bit / internal grinding head, thereby improving the stability and coordination of the equipment operation and the processing accuracy and efficiency of the connection holes. 2. When the shell needs to be positioned, the technician places the shell on the frame, and then the first power member drives the mounting plate to descend so that the bottom side of the positioning wheel is located below the joint surface of the shell. Then the second power member drives the switching block to rotate, so that the positioning wheel rotates around the rotation axis of the switching block until multiple positioning wheels simultaneously press against the outer peripheral wall of the shell, so that the shell and the rotating plate remain coaxial, and the shell is positioned. At this time, the shell bearing hole and the rotating plate remain coaxial, so that the center circle formed by the subsequently processed connecting hole remains coaxial with the shell bearing hole, thereby improving the processing accuracy, improving the connection strength and sealing performance of the shell, and saving power source at the same time; 3. When positioning the shell, under the action of the first power member, the mounting plate is at the height of the positioning state, and then the second power member works to realize the rotation of the switching block and drive the positioning wheel to rotate around the rotation axis of the switching block. At this time, the fixed ratchet rotates, and the movable ratchet overcomes the force of the elastic member and slides back and forth until the displacement sensor detects that the movable ratchet no longer slides. At this time, the displacement sensor transmits an electrical signal to the controller. If the first power makes the mounting plate at the height of the positioning state at this time, the controller makes the third power member work, so that the third power member drives the center rod to slide in the direction away from the rotating disk. Under the action of the connecting rod, the clamping block is rotated to a horizontal state. At this time, the ear plate is pressed against the clamping block, and drives the clamping block and the center tube to slide in the direction away from the rotating disk, so that the clamping block is pressed against the step of the outer ring of the bearing for supporting the outer ring of the bearing, thereby fixing the shell, realizing automatic control of shell positioning and shell fixation, reducing manual operation steps, and improving processing efficiency.

Figure 5The adjusting member 53 includes an adjusting block 531 elastically and slidably connected to the axis of the rotating disk 12. The elastic force applied to the adjusting block 531 is greater than the elastic force applied to the connecting rod 51. The sliding direction of the adjusting block 531 is consistent with the direction of the rotation axis of the rotating disk 12. One end of the adjusting block 531 movably protrudes from the top wall of the rotating disk 12. The protruding end of the adjusting block 531 is rotatably connected to the friction block 532. The rotation axis of the friction block 532 is consistent with the rotation axis of the rotating disk 12. The friction block 532 and the side wall of the frame 1 that are close to each other are movably pressed against each other. The friction block 532 is provided, which can effectively reduce the friction between the rotating disk 12 and the frame 1. The end of the adjusting block 531 close to the connecting rod 51 is inclined, and the end of the connecting rod 51 close to the rotating disk 12 is arc-shaped, and the arc end of the connecting rod 51 is pressed against the inclined side of the adjusting block 531.

[0051] When it is necessary to process the connecting hole 71 on the shell 7, the technician places the shell 7 on the frame 1. At this time, the drill bit 22, the internal grinding rod 23 and the positioning wheel 41 are all located above the shell 7, which is convenient for the technician to place the shell 7, and the drill bit 22 corresponds to the shell 7. At the same time, the adjustment block 531 slides up under the elastic force, so that the inclined side of the adjustment block 531 is pressed against the arc side of the plug-in rod 51, and drives the plug-in rod 51 to slide into the plug-in slot. At this time, the plug-in rod 51 is pressed against the inner wall of the plug-in slot to achieve locking of the rotating disk 12 and the mounting disk 11. The rotating disk 12 and the mounting disk 11 remain relatively fixed, and this is the initial state.

[0052] The technician then starts the equipment, at which time the positioning assembly 4 positions and fixes the housing 7 .

[0053] Then the first power member 13 drives the mounting plate 11 to descend, and then the second power member 353 works, and drives the transmission worm to rotate, drives the transmission worm wheel to rotate, and thus drives the inner ring gear 32 to rotate. Due to the self-locking characteristics of the worm gear, and the meshing clearance between the transmission worm wheel and the transmission worm is not easy to change with time or vibration and other factors, the precise and stable control of the number of rotations of the inner ring gear 32 is improved, thereby improving the processing accuracy.

[0054] At this time, the inner ring gear 32 drives the driven gear 31 to rotate, and the driven gear 31 is reversed, and the one-way bearing 243 is in a free rotation state. At this time, the rotating disk 12 and the mounting disk 11 remain relatively fixed. At the same time, under the action of the elastic member 333, the movable ratchet 332 is engaged with the fixed ratchet 331, and the limit block 341 is tightly pressed against the inner side wall of the limit hole 342, so that the movable ratchet 332 is not easy to rotate, so that the fixed ratchet 331 and the switching block 21 remain relatively fixed. At this time, the driven gear 31 drives the first drive gear 241 and the second drive gear 242 to rotate, thereby realizing the rotation of the four drill bits 22 / four internal grinding rods 23. Since the drill bit 22 corresponds to the shell 7 at this time, drilling of the shell 7 is realized.

[0055] After the drilling is completed, the first power member 13 and the second power member 353 work to make the mounting plate 11, the drill bit 22 and the internal grinding rod 23 move to the initial state, and then the second power member 353 drives the inner ring gear 32 to rotate, and drives the driven gear 31 to rotate. At this time, the driven gear 31 is in forward rotation, the one-way bearing 243 is in a locked state, the rotating disk 12 and the mounting plate 11 remain relatively fixed, so that the driven gear 31 drives the switching block 21 to rotate. At this time, the movable ratchet 332 overcomes the force of the elastic member 333 and slides in the direction away from the fixed ratchet 331, so that the fixed ratchet 331 and the movable ratchet 332 can rotate relative to each other until the switching block 21 rotates 90°. At this time, the internal grinding rod 23 corresponds to the housing 7, and the elastic member 333 makes the movable ratchet 332 press against the fixed ratchet 331, so that the switching block 21 is not easy to rotate, thereby ensuring that the internal grinding rod 23 is not easy to deflect.

[0056] Then the first power member 13 drives the mounting plate 11 to descend, and at the same time the second power member 353 works, driving the driven gear 31 to reverse, realizing the rotation of the drill bit 22 and the internal grinding wheel, thereby grinding the connecting hole 71 and improving the accuracy of the connecting hole 71. At this time, the drill bit 22 is idling, which is conducive to throwing off the metal debris attached to the drill bit 22 and realizing simple self-cleaning.

[0057] At the same time, the rotating disk 12 and the mounting disk 11 remain relatively fixed during drilling / grinding, thereby improving the stability of the drilling and grinding process. Multiple drill bits 22 and multiple internal grinding rods 23 work synchronously, effectively balancing the tangential force during the processing process, reducing the vibration and deflection of the drill bits 22 or the internal grinding rods 23, and further improving the accuracy of the connecting hole 71. In addition, during the drilling and grinding process, the precision error caused by secondary clamping and positioning is reduced, thereby improving the accuracy and processing efficiency of the connecting hole 71.

[0058] After the grinding is completed, the first power member 13 and the second power member 353 move the mounting plate 11, the drill bit 22 and the internal grinding rod 23 to the initial state again, and then the first power member 13 drives the mounting plate 11 to rise, so that the frame 1 is pressed against the top of the friction block 532, and drives the friction block 532 and the adjustment block 531 to slide down. At this time, the plug-in rod 51 is pressed against the inclined side of the adjustment block 531 under the elastic force, and slides in the direction close to the adjustment block 531, so that the plug-in rod 51 is separated from the plug-in slot, thereby unlocking the rotating disk 12 and the mounting disk 11, so that the rotating disk 12 and the mounting disk 11 maintain relative rotation.

[0059] Then the second power member 353 drives the driven gear 31 to rotate forward, and the one-way bearing 243 is in a locked state. At the same time, the elastic member 333 causes the movable ratchet 332 to press against the fixed ratchet 331, making the switching block 21 less likely to rotate than the rotating disk 12, so that the inner ring gear 32 and the driven gear 31 remain relatively fixed. At this time, the inner ring gear 32, the driven gear 31 and the rotating disk 12 rotate synchronously, thereby realizing the rotation of the rotating disk 12 until the rotating disk 12 rotates 45°. At this time, the switching block 21 rotates to the top of the four remaining connection holes 71 that need to be processed, and then repeat the above steps to realize the processing of the remaining four connection holes, thereby improving the processing efficiency.

[0060] Further, in order to facilitate the positioning of the housing 7, refer to Figure 5 、 Figure 6 and Figure 7 The positioning assembly 4 includes a positioning wheel 41 coaxially connected to the bottom end of the inner grinding rod 23. The diameter of the positioning wheel 41 is smaller than the diameter of the inner grinding rod 23. The outer peripheral wall of the positioning wheel 41 is movably pressed against the outer peripheral wall of the shell 7.

[0061] In order to facilitate the fixing of the housing 7, refer to Figure 5 、 Figure 6 and Figure 7 The positioning assembly 4 also includes a center tube 42 elastically slidably connected to the frame 1. The center tube 42 is coaxially arranged with the rotating disk 12 and is located below the rotating disk 12. A tightening block 43 is rotatably provided on the side wall of the center tube 42 close to the rotating disk 12. The rotation axis of the tightening block 43 is arranged horizontally, and the tightening block 43 and the housing 7 are used to support the step of the outer ring of the bearing. A center rod 44 is coaxially slidably provided on the center tube 42. The two ends of the center rod 44 protrude from the center tube 42. The top of the center rod 44 is rotatably connected with a connecting rod 45. The direction of the rotation axis of the connecting rod 45 is aligned with the tightening block 43. The rotation axis direction of the tightening block 43 is consistent, and the end of the connecting rod 45 away from its own rotation axis is rotatably connected to the end of the tightening block 43 away from its own rotation axis. There are multiple tightening blocks 43 and connecting rods 45, and multiple tightening blocks 43 correspond to multiple connecting rods 45 one by one. The multiple tightening blocks 43 and the multiple connecting rods 45 are evenly spaced around the circumference direction of the central tube 42. In this application, there are three tightening blocks 43 and connecting rods 45. In other embodiments, the tightening blocks 43 and connecting rods 45 can also be six, ten, eighteen, etc., and the layout method can be consistent with this application.

[0062] An ear plate 46 is fixed on the side wall near the center of the rotating disk 12. When the pressing block 43 rotates to a horizontal state, the bottom of the pressing block 43 presses against the top of the center tube 42, and the bottom of the ear plate 46 presses against the top of the pressing block 43.

[0063] In order to realize the automatic control of the fixing of the housing 7, a control member 47 for controlling the sliding of the central rod 44 is provided on the frame 1. Figure 5 、 Figure 6 and Figure 7 The control member 47 includes a displacement sensor 471 fixed to the top of the movable ratchet 332. A third power member 472 for driving the center rod 44 to slide is also fixed on the frame 1. In this application, the third power member 472 is a hydraulic cylinder. A controller 6 is also fixed on the frame 1. The displacement sensor 471, the first power member 13, the second power member 353 and the third power member 472 are all electrically connected to the controller 6.

[0064] When the shell 7 needs to be positioned and fixed, the technician places the shell 7 coaxially with the center tube 42 on the frame 1. At this time, the end of the tightening block 43 away from its own rotation axis is located close to the outer wall of the center tube 42, so that the tightening block 43 is not easy to hinder the placement of the shell 7 and is easy for the technician to operate.

[0065] Then the technician starts the equipment, and the controller 6 controls the first power part 13 to work, driving the mounting plate 11 to descend, and the bottom side of the positioning wheel 41 is located below the joint surface of the shell 7. At this time, the drill bit 22 and the internal grinding rod 23 are still located above the shell 7, and the rotating disk 12 and the mounting disk 11 remain relatively fixed, and are now in a positioning state.

[0066] Then the controller 6 controls the second power part 353 to work, driving the driven gear 31 to rotate forward. At this time, the one-way bearing 243 is in a locked state, and the rotating disk 12 and the mounting disk 11 remain relatively fixed, so that the driven gear 31 drives the switching block 21 to rotate. At this time, the movable ratchet 332 overcomes the force of the elastic member 333 and slides in the direction away from the fixed ratchet 331, so that the fixed ratchet 331 and the movable ratchet 332 can rotate relative to each other, thereby driving the switching block 21 to rotate, so that the positioning wheel 41 rotates around the rotation axis of the switching block 21, and the movable ratchet 332 slides up and down with the rotation of the switching block 21 until the displacement sensor 471 detects that the movable ratchet 332 no longer slides. At this time, the outer peripheral wall of the positioning wheel 41 is tightly pressed against the outer peripheral wall of the shell 7, so that the four positioning wheels 41 are pressed against the shell 7 at the same time, so that the shell 7 and the rotating disk 12 remain coaxial, thereby realizing the positioning of the shell 7.

[0067] At this time, the displacement sensor 471 transmits an electrical signal to the controller 6, and the first power makes the mounting plate 11 at a positioning height. The controller 6 makes the third power part 472 work, and drives the center rod 44 and the connecting rod 45 to descend, and makes the clamping block 43 move away from one end of its own rotation axis in the direction away from the center tube 42 until the clamping block 43 rotates to a horizontal state. At this time, the clamping block 43 and the side walls of the center tube 42 that are close to each other are pressed against each other, and at the same time, the ear plate 46 and the side walls of the clamping block 43 that are close to each other are pressed against each other, and drive the clamping block 43 and the center tube 42 to descend, so that the bottom side of the clamping block 43 presses against the step of the shell 7 used to support the outer ring of the bearing, thereby fixing the shell 7, reducing manual operation steps, and improving processing efficiency.

[0068] When the shell 7 is disassembled, the third power member 472 drives the center rod 44 to rise, causing the tightening block 43 to rotate to the initial position, thereby unlocking the shell 7, making it easier for technicians to remove the shell 7. At the same time, the center tube 42 slides upward under the elastic force to facilitate the next fixation.

[0069] The implementation principle of an integrated drilling and grinding device for processing a reducer housing in an embodiment of the present application is as follows: when it is necessary to process the connecting hole 71 on the housing 7, the technician places the housing 7 coaxially with the center tube 42 on the frame 1, and then the technician starts the equipment, and the controller 6 controls the first power part 13 to work, driving the mounting plate 11 to descend, so that the bottom side of the positioning wheel 41 is located below the joint surface of the housing 7, and the drill bit 22 and the internal grinding rod 23 are still located above the housing 7.

[0070] Then the controller 6 controls the second power member 353 to work, driving the rotating worm 352 to rotate, thereby driving the rotating worm wheel 351 and the inner ring gear 32 to rotate, and then driving the driven gear 31 to rotate forward. At this time, the driven gear 31 drives the switching block 21 to rotate, so that the positioning wheel 41 rotates around the rotation axis of the switching block 21. At the same time, the movable ratchet 332 slides back and forth up and down with the rotation of the switching block 21 until the displacement sensor 471 detects that the movable ratchet 332 no longer slides. At this time, the outer peripheral wall of the positioning wheel 41 is pressed against the outer peripheral wall of the shell 7, so that the four positioning wheels 41 are pressed against the shell 7 at the same time, so that the shell 7 and the rotating disk 12 remain coaxial, thereby realizing the positioning of the shell 7.

[0071] Then the displacement sensor 471 transmits the electrical signal to the controller 6, and the controller 6 activates the third power member 472 and drives the center rod 44 and the connecting rod 45 to descend, so that the clamping block 43 rotates to a horizontal state. At this time, the ear plate 46 presses against the top of the clamping block 43 and drives the clamping block 43 and the center tube 42 to descend, so that the bottom side of the clamping block 43 presses against the step of the shell 7 used to support the outer ring of the bearing, thereby fixing the shell 7.

[0072] Then the first power piece 13 drives the mounting plate 11 to rise, so that the bottom side of the positioning wheel 41 is located above the housing 7, and then the second power piece 353 drives the rotating worm 352 to rotate, so that the driven gear 31 rotates forward, drives the switching block 21 to rotate, and makes the drill bit 22 correspond to the housing 7, and then the first power piece 13 drives the mounting plate 11 to descend, and at the same time the second power piece 353 drives the rotating worm 352 to rotate, so that the driven gear 31 is reversed. At this time, the switching block 21 remains fixed, so that the driven gear 31 drives the first drive gear 241 and the second drive gear 242 to rotate synchronously, thereby driving the drill bit 22 and the internal grinding rod 23 to rotate. At this time, the internal grinding rod 23 is idling, and the drill bit 22 drills the housing 7.

[0073] After the drilling is completed, the first power member 13 drives the mounting plate 11 to rise until the positioning wheel 41 is located above the shell 7, and then the second power member 353 drives the rotating worm 352 to rotate, so that the driven gear 31 rotates forward, and drives the switching block 21 to rotate 90°. At this time, the internal grinding rod 23 corresponds to the shell 7, and then the first power member 13 drives the mounting plate 11 to descend, and at the same time the second power member 353 drives the rotating worm 352 to rotate, so that the driven gear 31 rotates in reverse, thereby realizing the grinding of the connecting hole 71.

[0074] After the first driving member 13 has been driven, the first driving member 13 drives the mounting plate 11 to rise until the frame 1 is pressed against the top of the friction block 532, and drives the friction block 532 and the adjusting block 531 to fall relative to the rotating plate 12. At this time, the connecting rod 51 is pressed against the inclined side of the adjustment and slides in the direction away from the plug-in slot under the elastic force, so that the plug-in block is separated from the plug-in slot, so that the rotating plate 12 and the mounting plate 11 keep rotating. Then the second driving member 353 drives the rotating worm 352 to rotate, realizing the positive rotation of the driven gear 31. Due to the action of the fixed ratchet 331 and the movable ratchet 332, the switching block 21 is less likely to rotate than the rotating plate 12, so that the inner gear ring 32, the driven gear 31 and the rotating plate 12 rotate synchronously, thereby realizing the rotation of the rotating plate 12 until the rotating plate 12 rotates 45°. At this time, the switching block 21 rotates to the top of the four remaining connecting holes 71 that need to be processed, and then the above steps are repeated to realize the processing of the remaining four connecting parts.

[0075] After the processing is completed, the third power member 472 drives the center rod 44 to rise, so that the tightening block 43 rotates to the initial position, thereby unlocking the shell 7, and the technician can remove the shell 7.

[0076] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
