Description

Technical Field

[0001] The present invention relates to the technical field of laser drilling, and in particular to a drilling device for winding shaft processing. Background Art

[0002] Laser drilling allows for precise drilling of holes in winding shafts. This technology utilizes a high-energy-density laser beam to instantly generate high temperatures on the material surface, enabling fast and precise drilling. It is suitable for materials of varying hardness and thickness, ensuring consistent hole diameter and surface quality, and is widely used in fields such as machinery manufacturing and aerospace.

[0003] When punching holes, in order to ensure the balance and stability of the winding shaft, the holes or slots at both ends are usually symmetrical. The laser welding arm and the device that fixes the winding shaft move in coordination with each other, and a single-end processing method is usually adopted. After completing the processing of one end, it automatically flips 180 degrees to process the other end. However, when installing and replacing winding shafts of different lengths, it is necessary to measure and fix the middle point to ensure accurate alignment after flipping. This centering process is not only time-consuming and labor-intensive, but also prone to human errors. Summary of the Invention

A side of the positioning rack is set as a tooth surface, the tooth surface of the positioning rack is meshed with the gear, the distance between one end of the positioning rack on one side and the gear is equal to the distance between the other end of the positioning rack on the other side and the gear, the placement rack is rotatably connected to a cover rack, a torsion spring symmetrically distributed along the cover rack is fixed between the placement rack and the cover rack, the placement rack is slidably connected to a limit frame, the limit frame contacts the cover frame, the limit frame slides upward to push the cover frame to automatically cover the placement rack, the positioning rack is fixedly connected to a push rack, the push rack is used to push the limit frame to slide upward.

[0006] As an improvement to the above solution, a side of the push frame close to the limiting frame is provided with an inclined surface, and the push frame is extruded and fitted with the limiting frame via the inclined surface.

[0007] As an improvement to the above scheme, it also includes a card rack, which is slidably connected to the placement rack. The frame of the laser punching machine has card holes symmetrically distributed along the rotating block. The card rack is slidably inserted into the card holes. A tension spring is fixed between the rotating block and the card rack. The push rack is fixed with at least one guide frame, which is used to push the card rack to slide in the opposite direction to pull it out of the card hole.

[0008] As an improvement to the above solution, a side of the guide frame close to the card holder is provided with an inclined surface, and the guide frame squeezes the card holder through the inclined surface to slide in the opposite direction.

[0009] As an improvement to the above scheme, it also includes an adjusting frame, which is slidably connected to the cover frame, and the cover frame is slidably connected to threaded frames symmetrically distributed along the cover frame, the symmetrically distributed threaded frames fit together, and the cover frame is slidably connected to guide plates symmetrically distributed along the cover frame, and the guide plates are used to lock adjacent threaded frames, and screws are threadedly connected between the symmetrically distributed threaded frames, the screws are slidably connected to the cover frame, and the screws are rotatably connected to the adjusting frame.

[0010] As an improvement of the above solution, the self-unlocking component includes a push rod corresponding to the guide plate, the push rod is arranged on the corresponding guide plate, the push rod rotates and contacts the limit frame, and a first spring is fixed between the guide plate and the corresponding push rod.

[0014] Beneficial effect: The present invention can automatically adjust a winding shaft of any length to be placed in the center on the placement rack simply by starting the second motor.

[0015] The present invention provides a guide frame on the push frame of the positioning frame that is squeezed and matched with the clamping frame, so that the positioning frame automatically locks the clamping frame when it is reset, thereby preventing the placement frame from rotating.

[0017] When the cover frame of the present invention is rotated backward to open, the threaded frame automatically disengages from the screw rod, so that the second spring resets and drives the adjustment frame to automatically slide upward to release the winding shaft, thereby preventing the operator from forgetting to reset the adjustment frame and preventing the adjustment frame from directly forcibly covering a thicker winding shaft next time, thereby preventing stress damage to related components.

[0018] In the centering contact process of the present invention, the elastic buffering effect of the third spring can realize soft contact between the compression frame and the winding shaft, thereby protecting the compression frame and the winding shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0031] Example 1: A punching device for winding shaft processing, such as Figures 1-4 As shown, it includes a laser punching machine 1, a first motor 2 is fixedly connected to the left side of the top of the frame of the laser punching machine 1, the output shaft of the first motor 2 is fixedly connected to a rotating block 201, the rotating block 201 is fixedly connected to a placement rack 3 for placing the winding shaft 101, the bottom of the placement rack 3 is fixedly connected to a second motor 4, the output shaft of the second motor 4 is fixedly connected to a gear 5, the placement rack 3 is slidably connected to a positioning rack 6 distributed symmetrically along the center of the gear 5 in the left and right directions, the positioning rack 6 is used to center the winding shaft 101, the side of the positioning rack 6 close to the gear 5 is set to a tooth surface, the tooth surface of the positioning rack 6 is meshed with the gear 5, and the distance between the right end of the front positioning rack 6 and the gear 5 is equal to the distance between the right end of the rear positioning rack 6 and the gear 5. The distance between the left end of the positioning frame 6 and the gear 5, the upper side of the placement frame 3 is connected to the cover frame 7 along the front and rear direction, the placement frame 3 and the cover frame 7 jointly limit the winding shaft 101, and the placement frame 3 and the cover frame 7 are fixed with a torsion spring 8 symmetrically distributed along the left and right sides of the cover frame 7. The rear side of the placement frame 3 is connected to the limit frame 9 for sliding along the up and down directions. The limit frame 9 contacts the cover frame 7, and the limit frame 9 slides upward to push the cover frame 7 to automatically rotate forward and cover the placement frame 3. A push frame 10 is fixed to the positioning frame 6, and the side of the push frame 10 close to the limit frame 9 is set to an inclined surface. The push frame 10 is squeezed and matched with the limit frame 9 through the inclined surface, so that the push frame 10 pushes the limit frame 9 to slide upward.

[0032] Before using the laser punching machine 1 to perform laser drilling on the winding shaft 101, first place the winding shaft 101 of any length horizontally on the placement rack 3, then control the output shaft of the second motor 4 to drive the gear 5 to rotate, and the gear 5 drives the front positioning rack 6 to move to the right, and the gear 5 simultaneously drives the rear positioning rack 6 to move to the left. If the winding shaft 101 of any length is placed in the center on the placement rack 3, the front and rear positioning racks 6 will contact the left and right sides of the winding shaft 101 at the same time. If the winding shaft 101 of any length is placed on the placement rack 3 to the left, the front positioning rack 6 will first contact the winding shaft 101 during the process of moving to the right, and the front positioning rack will As the positioning frame 6 continues to move to the right, it pushes the winding shaft 101 to move to the right until the positioning frame 6 on the rear side contacts the winding shaft 101 again during the process of moving to the left. At this time, the winding shaft 101 is automatically adjusted to the right to be placed in the center on the placement frame 3. Similarly, if a winding shaft 101 of any length is placed on the placement frame 3 to the right, the winding shaft 101 will eventually be automatically adjusted to the left to be placed in the center on the placement frame 3. That is, the present invention only needs to start the second motor 4 to automatically adjust the winding shaft 101 of any length to be placed in the center on the placement frame 3. The operation is simple and convenient, which is conducive to the rapid balance adjustment of the winding shaft 101 of any length.

[0033] During the movement of the above-mentioned positioning frame 6, the positioning frame 6 drives the pushing frame 10 to move synchronously. When the pushing frame 10 moves to contact the limit frame 9, the pushing frame 10 slides upward by squeezing the limit frame 9 through the inclined surface. The limit frame 9 pushes the cover frame 7 to rotate forward, and the torsion spring 8 is deformed, thereby automatically fixing the winding shaft 101 of any length that is placed in the center.

[0034] After completing the above-mentioned adjustment and fixing preparatory operations, the output shaft of the first motor 2 is controlled to drive the rotating block 201 to rotate, thereby driving the placement frame 3 to adaptively deflect, so that the winding shaft 101 can be adaptively deflected according to the drilling angle requirements of the laser drilling machine 1. After completing the laser drilling, the output shaft of the first motor 2 is controlled to drive the rotating block 201 to reverse and reset, and then the output shaft of the second motor 4 is controlled to drive the gear 5 to reverse, so that the positioning frame 6 moves in the opposite direction to disengage from the winding shaft 101, and the positioning frame 6 drives the pushing frame 10 to move in the opposite direction synchronously. When the pushing frame 10 moves in the opposite direction to disengage from the limit frame 9, the torsion spring 8 resets and drives the cover frame 7 to rotate backward, and the cover frame 7 pushes the limit frame 9 to slide downward.

[0035] like Figure 5 and Figure 6As shown, it also includes a card rack 11, which slides in the front and rear directions on the placement rack 3. A card hole is opened on the side of the frame of the laser punching machine 1 close to the card rack 11, which is symmetrically distributed along the left and right sides of the rotating block 201. The card rack 11 slides backward and is inserted into the card hole. A tension spring 12 is fixed between the rotating block 201 and the card rack 11. Two guide frames 13 are fixed to the rear side of the push rack 10. The side of the guide frame 13 close to the card rack 11 is set as an inclined surface. The guide frame 13 squeezes the card rack 11 through the inclined surface to slide forward, so that the card rack 11 is pulled out of the card hole of the laser punching machine 1.

[0036] When the positioning frame 6 drives the pushing frame 10 to move synchronously, the pushing frame 10 drives the guide frame 13 to move synchronously. When the guide frame 13 moves to contact the card frame 11, the guide frame 13 squeezes the card frame 11 through the inclined surface to slide forward, and the tension spring 12 is stretched, so that the card frame 11 is separated from the frame of the laser punching machine 1. At this time, the card frame 11 can rotate, so that the placement frame 3 can rotate, and then the rotating block 201 can rotate.

[0037] When the positioning frame 6 drives the pushing frame 10 to move in the opposite direction synchronously, the pushing frame 10 drives the guide frame 13 to move in the opposite direction synchronously. When the guide frame 13 is disengaged from the clamping frame 11, the tension spring 12 resets and drives the clamping frame 11 to slide backward, so that the clamping frame 11 is inserted into the clamping hole corresponding to the frame of the laser punching machine 1. At this time, the clamping frame 11 cannot rotate, so that the placement frame 3 cannot rotate, and the rotating block 201 cannot rotate with the output shaft of the first motor 2, to prevent the placement frame 3 from easily deflecting during the preparation operation for adjustment and fixation, causing the winding shaft 101 to slip off the placement frame 3.

[0038] like Figure 7 As shown, it also includes an adjusting frame 14, which slides on the cover frame 7 in the up and down directions, and the top of the cover frame 7 slides in the left and right directions and is connected to a threaded frame 15 symmetrically distributed along the cover frame 7, and the left and right threaded frames 15 fit together, and the top of the cover frame 7 slides in the front and back directions and is connected to a guide plate 16 symmetrically distributed along the front and back of the cover frame 7, and a guide groove is opened in the middle of the guide plate 16, and the guide groove of the guide plate 16 is composed of a straight groove and an oblique groove connected to each other, and the straight groove of the guide plate 16 is used to lock the adjacent threaded frames 15, and a screw 17 is threadedly connected between the symmetrically distributed threaded frames 15, and the screw 17 can slide in the up and down directions on the cover frame 7, and the bottom of the screw 17 is rotatably connected to the adjusting frame 14.

[0039] like Figure 8 and Figure 9As shown, it also includes a push rod 18 corresponding to the guide plate 16. The push rod 18 is threadedly connected to the corresponding guide plate 16, so that the push rod 18 can be threadedly disassembled. The push rod 18 rotates to contact the limit frame 9. A first spring 181 is fixed between the guide plate 16 and the corresponding push rod 18, and a second spring 19 symmetrically distributed along the adjustment frame 14 is fixed between the adjustment frame 14 and the cover frame 7.

[0040] In order to enable the cover frame 7 to adapt to clamping winding shafts 101 of different thicknesses, an adjustment frame 14 is provided on the cover frame 7 so that winding shafts 101 of any thickness can be fixed. The specific operation is as follows: when the cover frame 7 is opened, the end of the push rod 18 away from the first spring 181 contacts the top of the limit frame 9, and the first spring 181 is in a compressed state. When the cover frame 7 is rotated forward and closed, the push rod 18 gradually disengages from the top of the limit frame 9. At this time, the first spring 181 resets and drives the guide plate 16 to slide in the opposite direction, and the guide plate 16 drives the push rod 18 to slide in the opposite direction synchronously. At the same time, the guide plate 16 pushes the screw through the guide groove thereon The threaded frame 15 slides toward the side close to the screw 17 until the threaded frame 15 and the screw 17 are threadedly engaged. At this time, the guide groove of the guide plate 16 locks the threaded frame 15 through the straight groove to prevent the two threaded frames 15 from sliding away from each other and disengaging from the screw 17. Afterwards, the screw 17 can be rotated to make the screw 17 drive the adjusting frame 14 to slide downward until it contacts the surface of the winding shaft 101. The second spring 19 is compressed, thereby fixing the winding shaft 101 to prevent the thinner winding shaft 101 from having too much freedom of movement between the cover frame 7 and the placement frame 3, which affects the accuracy of laser drilling.

[0041] When the cover frame 7 is rotated backward to open, the push rod 18 is pushed upward by the top of the limit frame 9, so that the push rod 18 pushes the guide plate 16 to slide toward the side of the compressed first spring 181, and the guide plate 16 pushes the threaded frame 15 to slide toward the side away from the screw 17 through the guide groove thereon, so that the threaded frame 15 no longer limits the screw 17. At this time, the second spring 19 in the compressed state is reset to drive the adjustment frame 14 to automatically slide upward, preventing the operator from forgetting to reset the adjustment frame 14, preventing the adjustment frame 14 from being directly forced to cover the thicker winding shaft 101 next time, thereby preventing stress damage to related components.

[0042] In addition, since the push rod 18 is designed to be detachable by thread, when a batch of winding shafts 101 of the same size are laser punched, the push rod 18 is removed after the punching process of the first winding shaft 101 is completed, so that the subsequent threaded racks 15 of the batch do not need to be opened.

[0043] like Figure 1 and Figure 10As shown, a compression frame 20 corresponding to the positioning frame 6 is also included. The compression frame 20 is slidably connected to the positioning frame 6. A third spring 21 is fixed between the positioning frame 6 and the corresponding compression frame 20. The third springs 21 on the two positioning frames 6 are exactly the same. In this way, during the centering contact process, the elastic buffering effect of the third spring 21 can achieve soft contact between the compression frame 20 and the winding shaft 101, thereby protecting the compression frame 20 and the winding shaft 101.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
