Description

Technical Field

[0001] The present invention relates to the technical field of motor housing processing, and specifically relates to a drilling and tapping device for motor housing processing. Background Art

[0002] When processing a motor housing, several threaded holes need to be machined on the end face of the motor housing so that when assembling the motor end cover later, bolts can be used to cooperate with the threaded holes to connect the motor housing and the motor end cover. When machining the threaded holes on the end face of the motor housing, a drill press can be used for processing.

[0003] When using a drill press to process threaded holes, first, a drill bit needs to be installed on the chuck of the drill press, and the drill bit is used to drill holes on the end face of the motor housing. After the drilling is completed, the drill bit is replaced with a tap, and then the drill press and the tap are used in cooperation to tap the holes, and the threaded holes can be processed. Since it takes a long time to replace the tap, when processing a large number of motor housings, all the motor housings are drilled first, and then the tap is replaced for tapping. In this way, when processing the threaded holes of one motor housing, at least two clampings are required to complete the processing of the threaded holes of one motor housing, thereby resulting in low processing efficiency.

[0004] Therefore, we propose a drilling and tapping device for motor housing processing to solve the above problems. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: Please refer to Figures 1 - 10 , a drilling and tapping device for motor housing processing, including a drill press main body 1, a motor 2, a first pulley 3, a second pulley 4 and a transmission belt 5. The inner wall of the second pulley 4 is fixedly connected with a driving shaft, and one end of the driving shaft is rotatably connected with the drill press main body 1. A driving component is arranged on one side of the driving shaft. The outer wall of the driving shaft is slidably sleeved with a sleeve 6, and a reversing pipe is rotatably sleeved on the sleeve 6. The lower end of the reversing pipe is fixedly connected with a housing 7, and two clamping components are arranged in the housing 7.

[0031] As can be seen from the above structure, by arranging two clamping components to cooperate with the reversing pipe, etc., during use, a drill bit and a tap can be respectively installed on the two clamping components. When using this device, the drill bit can be used for drilling first. After the drill bit finishes drilling, the reversing pipe can drive the two clamping components to swap positions, so that the tap is swapped to the position of the drill bit, and then the tap can perform tapping. In this way, when machining the motor housing, drilling and tapping can be completed at one time. For the machining of the motor housing, it only needs to be clamped up and down once at least, saving the clamping required during the machining of the motor housing, thereby improving the machining efficiency of this device for the motor housing.

[0032] Furthermore, the drive shaft includes a shaft rod main body 8, and a rectangular hole is formed at the lower end of the shaft rod main body 8. A rectangular rod 9 is slidably connected to the inner wall of the rectangular hole, and one end of the rectangular rod 9 penetrates through the housing 7 and extends into the housing 7. One end of the rectangular rod 9 located inside the housing 7 is fixedly connected to a first gear 10; by arranging the drive shaft composed of the shaft rod main body 8, the rectangular rod 9 and the first gear 10, the two clamping components can be driven to rotate, and at the same time, during use, the drive shaft can freely expand and contract.

[0033] Furthermore, the drive assembly includes a rotating shaft 11 rotatably connected to the drill press main body 1, and a second gear 12 is sleeved on the outer wall of the rotating shaft 11. A strip-shaped groove is formed on the outer wall of the sleeve 6, and a rack 13 is fixedly connected to the inner wall of the strip-shaped groove. The rack 13 meshes with the second gear 12. A first torsion spring 14 is sleeved on the outer wall of the rotating shaft 11, and one end of the first torsion spring 14 is fixedly connected to the rotating shaft 11, and the other end of the first torsion spring 14 is fixedly connected to the drill press main body 1. One end of the rotating shaft 11 penetrates through the drill press main body 1 and extends to the outside of the drill press main body 1, and a handle 15 is fixedly connected to the end of the rotating shaft 11 located outside the drill press main body 1; by arranging the cooperation of the rotating shaft 11 and the handle 15, etc., the sleeve 6, the reversing pipe, the clamping components, the drill bit and the tap can be driven to move downward through the handle 15, so that the drill bit and the tap can complete drilling and tapping.

[0034] Further, the commutation tube includes a tube body 16 rotatably sleeved on the outer wall of the sleeve 6. Two vertical grooves 17 and two inclined grooves 18 are formed in the outer wall of the tube body 16. The two ends of the two inclined grooves 18 are respectively communicated with the two vertical grooves 17. A relief groove 19 is formed in the side wall of the inclined groove 18. A retaining shaft 20 is rotatably connected to the inner wall of the relief groove 19. One end of the retaining shaft 20 is fixedly connected with a baffle 21. A second torsion spring 22 is sleeved on the outer wall of the retaining shaft 20. One end of the second torsion spring 22 is fixedly connected with the retaining shaft 20, and the other end of the second torsion spring 22 is fixedly connected with the relief groove 19. A retaining block 36 is fixedly connected to the inner wall of the drill press main body 1, and one end of the retaining block 36 is located inside the vertical groove 17. By arranging the cooperation of the tube body 16 and the retaining block 36, etc., when in use, the rotating shaft 11 is rotated through the handle 15. The rotating rotating shaft 11 drives the second gear 12 to rotate. The rotating second gear 12 drives the rack 13 to move downward. The downward moving rack 13 drives the sleeve 6 to move downward. The downward moving sleeve 6 drives the tube body 16 to move downward. The downward moving tube body 16 drives the housing 7 and the clamping assembly to move downward. The downward moving clamping assembly drives the drill bit to move downward, so that the drill bit can drill holes in the motor housing. After the drilling is completed, the handle 15 is released. At this time, the first torsion spring 14 drives the rotating shaft 11 to reverse. The reversing rotating shaft 11 drives the second gear 12, the sleeve 6 and the tube body 16, etc. to reset.

[0035] When the tube body 16 moves upward and resets, when the tube body 16 moves upward to a certain extent, the cooperation of the retaining block 36, the baffle 21 and the inclined groove 18 causes the tube body 16 to rotate half a turn. The tube body 16 that rotates half a turn drives the housing 7 and the clamping assembly to rotate half a turn, so that the drill bit and the tap are replaced.

[0036] Further, the clamping assembly includes a third gear 23 arranged in the housing 7. The third gear 23 meshes with the first gear 10. A connecting pipe 24 is fixedly connected to the lower end of the third gear 23. The lower end of the connecting pipe 24 penetrates through the housing 7 and extends to the outside of the housing 7. A chuck 25 is fixedly connected to the end of the connecting pipe 24 located outside the housing 7. A support spring 26 is sleeved on the outer wall of the connecting pipe 24. By arranging the cooperation of the third gear 23, the connecting pipe 24 and the chuck 25, etc., the chuck 25 can install a drill bit or a tap. When the first gear 10 rotates, the first gear 10 can drive the third gear 23, the connecting pipe 24, the chuck 25, the drill bit and the tap to rotate.

[0037] Further, one end of the third gear 23 is fixedly connected to a slide rod 27, and one end of the slide rod 27 penetrates through the housing 7 and extends to the outside of the housing 7. A cavity 28 is formed inside the housing 7, and a spring piece 29 is arranged in the cavity 28. One end of the spring piece 29 is fixedly connected to a fixing pin 30. A fixing hole 31 is formed in one side side wall of the slide rod 27. The side walls of the drill press main body 1 are respectively fixedly connected with a pressing plate 32 and a connecting frame 33, and a magnet 34 is fixedly connected to one side side wall of the connecting frame 33; by setting the slide rod 27, the fixing hole 31 and the fixing pin 30 to be used in cooperation, after the drilling is completed, when the tap rotates to the position of the drill bit and the housing 7 and the clamping assembly continue to move upward, the slide rod 27 on one of the clamping assemblies abuts against the pressing plate 32, so that the slide rod 27 is pressed down. The pressed-down slide rod 27 drives the clamping assembly and the tap to move downward. After the slide rod 27 moves downward to a certain position, the spring piece 29 pushes the fixing pin 30, so that the fixing pin 30 is inserted into the fixing hole 31 to limit the slide rod 27 and the tap, etc., to prevent the tap from moving randomly. Furthermore, when using the tap for tapping at this time, the tap will not be pushed by the workpiece;

[0038] When the other clamping assembly for fixing the drill head moves up to the highest position, the fixing pin 30 is located on one side of the magnet 34. At this time, the magnet 34 attracts the fixing pin 30, so that one end of the fixing pin 30 moves out of the fixing hole 31. At this time, the supporting spring 26 will push the third gear 23, the slide rod 27, the connecting pipe 24, the chuck 25 and the drill head to move upward. In this way, the tap moves downward and the drill head moves upward, which can avoid the problem that the drill head affects the tap processing during tapping. Then, tapping can be carried out through the handle 15.

[0039] Further, one end of the supporting spring 26 is fixed to the housing 7, and the other end of the supporting spring 26 is fixedly connected to a supporting ring 35. One side side wall of the supporting ring 35 contacts the third gear 23; by setting the supporting ring 35, it can be avoided that one end of the supporting spring 26 directly rubs against the third gear 23 and is damaged, thereby protecting the supporting spring 26.

[0040] In the present invention, before use, a drill bit is installed on one chuck 25, and a tap is installed on the other chuck 25. Then, the motor 2 is started. The started motor 2 drives the shaft rod main body 8, the rectangular rod 9 and the first gear 10 to rotate through the first pulley 3, the second pulley 4 and the transmission belt 5. The rotating first gear 10 can drive the third gear 23 to rotate. The rotating third gear 23 drives the two connecting pipes 24 and the chuck 25 to rotate. The rotating chuck 25 can drive the drill bit and the tap to rotate;

[0041] When in use, rotate the rotating shaft 11 by turning the handle 15. The rotating rotating shaft 11 drives the second gear 12 to rotate. The rotating second gear 12 drives the rack 13 to move downward. The downward-moving rack 13 drives the sleeve 6 to move downward. The downward-moving sleeve 6 drives the pipe body 16 to move downward. The downward-moving pipe body 16 drives the housing 7 and the clamping assembly to move downward. The downward-moving clamping assembly drives the drill bit to move downward, so that the drill bit can drill holes in the motor housing. After the drilling is completed, release the handle 15. At this time, the first torsion spring 14 drives the rotating shaft 11 to reverse. The reversing rotating shaft 11 drives the second gear 12, the sleeve 6, the pipe body 16, etc. to reset;

[0042] When the pipe body 16 moves upward and resets, when the pipe body 16 moves upward to a certain extent, the stopper 36, the baffle 21 and the inclined groove 18 cooperate to make the pipe body 16 rotate half a turn. The pipe body 16 that rotates half a turn drives the housing 7 and the clamping assembly to rotate half a turn, so that the drill bit and the tap are transposed. Since the tap is changed to the position of the drill bit, the next time it is operated, it is the same as operating the drill bit to drill holes, so that the tap can be moved downward to perform tapping;

[0043] And after the drill bit and the tap are transposed, the pipe body 16 drives the clamping assembly to continue to move upward. After the clamping assembly continues to move upward to a certain position, the sliding rod 27 on one of the clamping assemblies abuts against the pressing plate 32, so that the sliding rod 27 is pressed downward. The downward-pressing sliding rod 27 drives the clamping assembly and the tap to move downward. After the sliding rod 27 moves downward to a certain position, the spring piece 29 pushes the fixing pin 30, so that the fixing pin 30 is inserted into the fixing hole 31 to limit the sliding rod 27, etc.;

[0044] When the other clamping assembly for fixing the drill bit moves to the highest position, the fixing pin 30 is located on one side of the magnet 34. At this time, the magnet 34 attracts the fixing pin 30, so that one end of the fixing pin 30 moves out of the fixing hole 31. At this time, the supporting spring 26 will push the third gear 23, the sliding rod 27, the connecting pipe 24, the chuck 25 and the drill bit to move upward. In this way, the tap moves downward and the drill bit moves upward, which can avoid the problem that the drill bit affects the tap processing during tapping. Then, tapping can be performed by turning the handle 15. (The method of tapping is basically the same as that of drilling, and will not be described here).
