Description

An automatic flipping processing device for two-stage punching and enlarging of motor housing Technical Field

[0001] This invention relates to the field of machining technology, and in particular to an automatic flipping machining device for a two-stage punching and enlarging process for motor housings. Background Technology

[0002] In the manufacturing process of motor housings, punching and reaming are two critical steps. Traditional processing methods typically employ manual operation or semi-automated equipment. In manual operation, workers must manually place the motor housing onto the punching equipment for punching, and then manually transfer it to the reaming equipment for reaming. This method is not only labor-intensive but also inefficient. Furthermore, due to human error, it easily leads to low processing precision and inconsistent product quality. Simultaneously, the frequent contact between workers and the punching and reaming equipment during manual operation poses significant safety hazards and increases the risk of workplace injuries.

[0003] While existing semi-automated equipment has improved processing efficiency to some extent, several problems remain. For example, some equipment can only automate a single process, either punching or reaming, and cannot automate two processes continuously. Manual transfer operations are still required in intermediate stages, failing to completely solve the problems of high labor intensity and safety hazards. Furthermore, some equipment lacks stable fixation and support for the motor housing during punching and reaming, easily causing the motor housing to wobble during processing, affecting processing accuracy and product quality. In addition, existing equipment is inadequate in waste disposal; waste generated during punching cannot be collected promptly and effectively, easily accumulating around the equipment and affecting its normal operation and working environment. Therefore, developing a processing device capable of continuous automated processing of both punching and reaming of motor housings, with stable support and effective waste disposal functions, is of significant practical importance.

[0023] An embodiment of the present invention: As shown in Figures 1-6, a dual-process punching and reaming automatic flipping processing device for motor housing includes a feeding unit, a punching unit, and a reaming unit. The feeding unit includes a lifter 1 and a material rack. The motor housing is vertically sleeved on the outside of the material rack. The lifter 1 is arranged side by side with the material rack and is connected to it in a transmission manner. The punching unit includes a drive box 2. The top surface of the drive box 2 is provided with a punching assembly and a drive component. The drive component is connected to the punching assembly in a transmission manner. A first robot 3 is provided on one side of the drive box 2 for transferring the motor housing from the material rack to the punching assembly. The reaming unit is located on the side of the drive box 2 away from the material rack. A second robot 4 is provided between the reaming unit and the drive box 2 for transferring the motor housing from the punching assembly to the reaming unit.

[0024] The design is further optimized. The material rack includes a base 5, with a guide rail 6 on the top surface of the base 5. A mounting plate 7 is slidably connected to the guide rail 6. Several material columns 8 are fixedly connected at equal intervals on the top surface of the mounting plate 7. The motor housing is fitted onto the outside of the material columns 8. One of the material columns 8 is directly opposite the elevator 1 and is detachably connected. The bottom surface of the mounting plate 7 has a guide groove that matches the guide rail 6. The mounting plate 7 slides relative to the base 5, allowing adjustment of its position on the base 5. This enables alignment between different material columns 8 and the elevator 1, facilitating the lifting of the motor housings on different material columns 8.

[0025] The design is further optimized. The lifting device 1 includes a lifting platform 9 and a lifting block 10. The lifting platform 9 and the lifting block 10 are connected by a drive mechanism. One end of the lifting block 10 has a slot 11, into which a first fork plate 12 is inserted. One end of the first fork plate 12 is adapted to and forks into one end of the motor housing. The first fork plate 12 first forks into the bottom end of the motor housing, pushing the mounting plate 7 to move the first fork plate 12 upward, thereby moving the motor housing upward.

[0026] Furthermore, the elevator 9 can drive the lifting block 10 through a lead screw or threaded rod to lift the first fork plate 12 that is inserted into the lifting block 10, thereby lifting several motor housings. This is existing technology and will not be described in detail here.

[0027] The design has been further optimized, with the punching components comprising several parts, the specific number depending on the specifications of the motor housing. The punching assembly includes a trolley 13, with slide bars 14 slidably connected to both sides of the trolley 13. The slide bars 14 are fixedly connected to the top surface of the drive box 2. A hinge seat 15 is fixedly connected to one end of the slide bar 14. A push wheel 16 is rotatably connected to one end of the hinge seat 15. The push wheel 16 is connected to the drive component. The trolley 13 slides along the length of the slide bars 14 through the two slide bars 14. A punch block 17 is fixedly connected to the other end of the trolley 13. A pressure head 18 is fixedly connected to one end of the punch block 17. One end of the pressure head 18 is adapted to and detachably connected to the outer side of the motor housing. A guide hole 19 is opened on the end face of the pressure head 18. By pressing the pressure head 18 against the outer side of the motor housing, it can abut against the motor housing when the punch is punching the mounting hole, providing sufficient support force during the punching process. Furthermore, the drive component can abut against one side of the push wheel 16, further increasing the rigidity of the trolley 13. The bottom end of the punch block 17 is provided with a material leakage groove 20, and the material guide hole 19 is connected to the material leakage groove 20. The material beans punched off by the motor housing will be continuously guided into the material leakage groove 20 through the material guide hole 19, and fall onto the top surface of the drive box 2 through the material leakage groove 20. Furthermore, the top surface of the drive box 2 is provided with a material leakage hole, which is connected to the waste collection hopper. This is existing technology and will not be described in detail here. One end of the press head 18 is provided with a punch, and the punch is fixedly connected to the drive box 2.

[0028] Further optimizing the design, the punch includes a mounting plate 21 with a through hole at its center. A mounting cylinder 22 is fixedly installed inside the through hole, and a pusher 23 is slidably connected inside the mounting cylinder 22. Several sliding holes 24 are formed at the top of the side wall of the mounting cylinder 22, and punches are slidably connected inside the sliding holes 24. The punches are connected to the pusher 23 via a transmission connection. A motor housing is fitted onto the top of the outer side of the mounting cylinder 22, and the bottom surface of the motor housing abuts against the top surface of the mounting plate 21. The driving components are fixedly connected to the pusher 23 and the driving box 2, respectively. The sliding holes 24 are square holes, and spring grooves 25 are formed on opposite side walls of the square holes. Springs 26, which are leaf springs, abut against the springs 25, and the middle part of the springs 26 abuts against the punches. The top side of the push core 23 is provided with a T-shaped groove. One side of the punch seat 27 of the punch is fixedly connected with a guide bar that matches the T-shaped groove. The guide bar can push the punch 28 to move in the sliding hole 24 during the up and down movement of the push core 23, so as to punch and retract the mounting hole on the side wall of the motor housing and prevent material jamming.

[0029] Furthermore, the spring 26 can use the elastic force of the leaf spring to push the punch seat 27 to reset, thereby resetting the punch 28 and preventing the punch 28 from getting stuck in the motor housing and being unable to retract.

[0030] The design is further optimized so that the punch includes a punch holder 27 and a punch 28. Both ends of the punch holder 27 abut against springs 26. A mounting hole is provided on the side of the punch holder 27. One end of the punch 28 is fitted into the mounting hole and detachably connected. The mounting of the punch 28 with the punch holder 27 facilitates maintenance and replacement of the punch 28. Pin holes are provided on the sides of both the punch holder 27 and the punch 28. The punch holder 27 and the punch 28 are detachably connected via the pin holes and pins 29. The pin holes and pins 29 position and fix the punch 28 and the punch holder 27, preventing the punch 28 from dislodging from the punch holder 27 and facilitating the installation and adjustment of the punch 28.

[0031] Further optimizing the design, the driving components include a first telescopic component 30 and a second telescopic component 31. The bottom surface of the push core 23 is fixedly connected to the first telescopic component 30. Several second telescopic components 31 are provided, and each second telescopic component 31 is fixedly connected to the drive box 2. A push rod 32 is fixedly connected to each second telescopic component 31. The bottom end of the push rod 32 has a square structure, and the push rod 32 is slidably connected to the drive box 2. The top end of the push rod 32 is round, and the side of the top end of the push rod 32 is connected to the push wheel 16 for transmission. The square bottom end of the push rod 32 can stop rotation during the up-and-down movement of the push rod 32, making it convenient to drive the push wheel 16 using the round end of the push rod 32.

[0032] Furthermore, the top of the push rod 32 is provided with a slope to reduce the driving force of the push rod 32 on the push wheel 16.

[0033] Furthermore, both the first telescopic member 30 and the second telescopic member 31 are hydraulic cylinders, which can use the thrust of the hydraulic cylinder to push the push rod 32 to limit the movement of the trolley 13.

[0034] A further optimized design includes a reaming unit comprising a drill box 33. Several CNC drill chucks 34 are fixedly connected to the inner cavity of the drill box 33. The drill chucks 34 are driven and adjusted by a CNC lifting device, and each chuck holds a drill bit. The rotation of the drill chucks 34 drives the drill bit to perform reaming operations on the mounting hole. The CNC lifting device is existing technology and will not be described in detail here. A support assembly is positioned directly opposite the lower end of each drill chuck 34. A motor housing is fitted onto one end of the support assembly, and the other end of the support assembly is rotatably connected to the drill box 33.

[0035] In a further optimized design, an adapter 35 is fixedly connected to the side of the drive box 2 away from the material rack, and the top surface of the adapter 35 is in limiting contact with one end of the motor housing.

[0036] Another embodiment of the present invention: As shown in Figures 7-8, the support assembly includes a chute 44, which is fixedly connected to the drill box 33. A slide plate 45 is fixedly connected to the inner wall of the chute 44. The slide plate 45 is inclined and is used to slide the motor housing that falls onto the slide plate 45 out by gravity. One end of the slide plate 45 is connected to a conveyor belt, which transports the motor housing that falls onto it to the end away from the drive box 2 for collection. The other end of the slide plate 45 is connected to a support roller 38. The motor housing is sleeved on the outside of the support roller 38. One end of the motor housing is forked with a second fork plate. The second fork plate is fixedly connected to a material feeder. The two ends of the material feeder slide in contact with the two sides of the chute 44 respectively. Furthermore, the material feeder has its own drive mechanism, which can reciprocate along the chute 44 under the control of an external control mechanism.

[0037] One end of the support roller 38 is fixedly connected to a support box 36. The support box 36 has a hollow structure, and one end of the support box 36 is drivenly connected to a servo motor 37. The servo motor 37 is fixedly connected to the drill box 33. The support roller 38 has a hollow structure, and one end of the support roller 38 has two clearance holes. A side top strip 39 is rotatably connected to the inner wall of the clearance holes. The side top strip 39 has an arc-shaped structure. One end of the side top strip 39 is fixedly connected to a top hammer 40, and the other end of the side top strip 39 is fixedly connected to a permanent magnet buckle 41. The two permanent magnet buckles 41 are arranged opposite each other and have the same magnetic poles. Through the interaction of the two permanent magnet buckles 41, the top hammer 40 can be flipped into the inner cavity of the support roller 38, avoiding interference and jamming when the second robot 4 puts the motor housing in. One end of the side top strip 39 is slidably abutted against a top block 42. The top block 42 is fixedly connected to a third telescopic member 43, which is fixedly connected to the inner cavity of the support box 36.

[0038] The third telescopic component 43 extends and pushes the top block 42 toward the permanent magnet buckle 41. When the top block 42 contacts the other end of the side top bar 39, it will continue to push the side top bar 39 to flip. Then the top hammer 40 will gradually extend out of the clearance hole and abut against the inner wall of the motor housing to prevent the motor housing from rotating during the hole enlargement process.

[0039] Furthermore, the third telescopic component 43, servo motor 37, first robot 3, second robot 4, elevator 9, first telescopic component 30 and second telescopic component 31 are all connected to a controller. The controller is a PLC controller, which can achieve stable operation of each process step through program control. This is existing technology and will not be described in detail here.

[0040] The working process of this embodiment is as follows: In the initial state, the motor housing is vertically sleeved on the outside of the material column 8 of the material rack. The mounting plate 7 of the material rack can slide on the guide rail 6 of the base 5 to adjust the alignment of different material columns 8 with the elevator 1. The lifting mechanism 9 of the elevator 1 drives the lifting block 10 through a lead screw or threaded rod. The first fork plate 12 inserted into the slot 11 of the lifting block 10 forks into the bottom end of the motor housing, pushing the mounting plate 7 to drive the first fork plate 12 upward, thereby driving the motor housing upward to a suitable height.

[0041] The first robot 3 transfers the lifted motor housing to the punch head 18 of the punching assembly and places it on the outside of the mounting cylinder 22. The punch head 18 abuts against the outer side of the motor housing, providing sufficient support for the punching process. Simultaneously, the first telescopic member 30 of the drive unit pushes the pusher 23 to slide within the mounting cylinder 22. The pusher 23 pushes the punch seat 27 via a guide bar, causing the punch 28 to move within the sliding hole 24, punching mounting holes in the side wall of the motor housing. The punched material is guided through the guide hole 19 into the discharge trough 20, and then falls into the waste collection hopper through the discharge hole on the top surface of the drive box 2. After punching, the spring 26 pushes the punch seat 27 to reset, causing the punch 28 to retract and prevent jamming. The other end of the first robot 3 transfers the punched motor housing to the adapter 35.

[0042] The second robot 4 transfers the motor housing from the adapter 35 to the support assembly of the reaming unit. The motor housing is fitted onto the outside of the support roller 38 of the support assembly. The third telescopic component 43 extends and pushes the top block 42, causing the side top bar 39 to flip. The top hammer 40 extends out of the clearance hole and abuts against the inner wall of the motor housing to prevent it from rotating. The CNC drill chuck 34 in the drill box 33 adjusts its position through a CNC lifting device, driving the drill bit to chamfer and ream the outside of the mounting hole. After processing, the motor housing falls into the slide plate 45 and slides onto the conveyor belt by gravity, where it is transported to the end away from the drive box 2 for collection. The entire process is controlled by a PLC controller to ensure stable operation of each component, realizing automated processing of punching and reaming of the motor housing, improving processing efficiency, and reducing labor intensity and safety hazards.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
