These lock pins will be inserted into the jacks of the door frame after the door lock is locked to enhance the safety of the door lock. The lock pin is usually cylindrical. In order to be installed in the lock body, its top end and the outer periphery need to be drilled. The equipment used for lock body drilling in the prior art, such as a lock body drilling device disclosed in the existing announcement number CN220073336U, clamps the workpiece to be drilled, and then the drill bit is lowered to perform a drilling. After drilling once, the worker releases the clamp and adjusts the position of the workpiece to be drilled, and performs a second drilling. In this way, the drilling work of the two positions of the lock pin is completed twice. Two drilling devices can also be used.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 11 , Fig.14 and Fig.15 , this embodiment provides a technical solution: a lock body drilling device for fingerprint lock production, including a drilling device 1, a clamping component 2, a moving component 3 and an alignment component 4, the drilling device 1 is composed of a drilling platform 101 and a drilling component 102 fixed on the drilling platform 101, the drilling component 102 is composed of a lifting component 1021 fixed on the top of the drilling platform 101, a drill body 1022 fixed at the moving end of the lifting component 1021, and two driving racks 1023 fixed at the moving end of the lifting component 1021. The drilling platform 101, the lifting component 1021 and the drill body 1022 included in the drilling device 1 are all prior arts. In the prior art, by fixing the drilling workpiece on the drilling platform 101, and then driving the lifting component 1021 to drive the drill body 1022 to descend, and driving the drill body 1022 to work at the same time, when the drill body 1022 descends to the point where its drilling end contacts the outer wall of the drilling workpiece, it is possible to perform drilling work by continuing to drive it to descend; The clamping assembly 2 is slidably mounted on the top of the drilling platform 101, and is used to clamp the drilling workpiece and drive the drilling workpiece to flip during the drilling process. The clamping assembly 2 has two clamping stations 200, and there is always a clamping station 200 facing the drilling end of the drilling assembly 102, that is, there is always a clamping station 200 on the drilling station 100; By arranging two clamping stations 200 on the clamping assembly 2, the workpiece on the clamping station 200 of a clamping assembly 2 facing the drilling end of the drilling assembly 102 can be loaded and unloaded on the other clamping station 200 which is not on the drilling station 100 while the drilling work is being carried out. Therefore, after the drilling of the workpiece on the drilling station 100 is completed, the clamping assembly 2 can be directly driven to move, and the positions of the two clamping stations 200 can be switched, so that the newly loaded workpiece can directly reach the drilling station 100, and then the drilling work can be carried out directly. Compared with the traditional drilling equipment 1, which needs to release the clamping state of the drilling workpiece at the drilling station 100, then unload the workpiece, and finally load the new drilling workpiece and clamp the operation steps, the operation steps between the two drilling operations are greatly shortened, and the drilling processing efficiency of the lock body is improved; At the same time, since the clamping assembly 2 can drive the drilling workpiece to flip, when the drill body 1022 descends to drill a hole in the lock body and then rises, the drilling workpiece can be driven to flip, and then the drill body 1022 descends again to drill a second hole, so that the two drillings of a lock body do not need to be manually transferred between two drilling devices 1, but can be completed twice on the same device, and the two drillings only need to rotate the lock body, without the need for repeated clamping and unclamping operations of the lock body, which greatly reduces the drilling operation steps of the lock body and further improves the drilling efficiency of the lock body. The moving assembly 3 is fixed on the top of the drilling platform 101, and is used to drive the clamping assembly 2 to move and switch the positions of the two clamping stations 200. When the clamping assembly 2 needs to move and switch the positions of the clamping stations 200, the clamping assembly 2 can be driven to move by driving the moving assembly 3; The alignment component 4 is installed on the clamping component 2, and performs auxiliary positioning when the drilling workpiece is installed on the clamping component 2. When the drilling workpiece is inserted into the clamping component 2, the alignment component 4 performs the receiving work of the drilling workpiece below; The clamping assembly 2 includes two movable plates 22 fixed to each other and slidably connected to the drilling platform 101 through a first linear slide rail 21, a frame 24 is symmetrically slidably installed on the top of the movable plate 22 through a second linear slide rail 23, and a first rotating shaft 25 is rotatably connected to the frame 24 through a bearing, and a clamping block 26 is fixed to one end of the two first rotating shafts 25 above each movable plate 22 that are close to each other, and a V-shaped recess is formed on one side of the two clamping blocks 26 above each movable plate 22 that are close to each other, and the drilling workpiece is clamped in the V-shaped recess of the two clamping blocks 26 when being clamped, and a flipping assembly 27 for driving the drilling workpiece to flip is installed on the frame 24, and a driving assembly 28 for driving the frame 24 to move and perform clamping work is installed on the movable plate 22; When the movable plate 22 is at one side of the drill body 1022 and is not at the drilling station 100, the two frame frames 24 on the movable plate 22 are driven away from each other, thereby driving the two clamping blocks 26, so that the clamping blocks 26 are separated from the outer wall of the clamped workpiece, and a new drilled workpiece is placed between the two clamping blocks 26 after the drilled workpiece is unloaded, and the bottom of the drilled workpiece is supported on the top of the alignment component 4, and then the movable plate 22 is driven to move to the drilling station 100, and the two frame frames 24 on the movable plate 22 are driven to move closer to each other, and the drilled workpiece is clamped by the clamping blocks 26; The flip assembly 27 includes a second rotating shaft 271 rotatably connected to the middle position of the top surface of the frame 24 through a bearing, a driving wheel 272 is fixed to the middle of the second rotating shaft 271, a groove wheel 273 is fixed to the end of the first rotating shaft 25 away from the clamping block 26, the driving wheel 272 cooperates with the groove wheel 273, and a driven gear 274 is rotatably installed on the end of the second rotating shaft 271 away from the frame 24 through a one-way bearing, a first friction washer 275 is fixed to the side of the driven gear 274 close to the driving wheel 272, one side of the first friction washer 275 contacts the outer wall of the driving wheel 272, a second friction washer 276 is fixed to the side of the driving wheel 272 away from the first friction washer 275, the side of the second friction washer 276 away from the driving wheel 272 contacts the outer wall of the frame 24, and the driven gear 274 is driven by the drilling assembly 102; The two driving racks 1023 are respectively opposite to the two driven gears 274 on the drilling station 100, and the moving plate 22 is symmetrically provided with avoidance holes 221, and when the moving plate 22 is located on the drilling station 100, the driving racks 1023 are directly opposite to the avoidance holes 221; When the drill body 1022 descends to perform the first drilling operation on the drilling workpiece on the drilling station 100, the drill body 1022 descends to drive the rack 1023 to rotate the driven gear 274. Under the action of the one-way bearing, the driven gear 274 cannot drive the second rotating shaft 271 to rotate. Only when the drill body 1022 rises, the driving rack 1023 follows the rise and drives the driven gear 274 to rotate, and then the second rotating shaft 271 can be driven to rotate. It should be emphasized that the first friction washer 275 and the second friction washer 27 The function of 6 is to ensure the stability of the driving wheel 272 and prevent it from rotating randomly when the driving rack 1023 is separated from the driven gear 274, and to ensure the stability between the driven gear 274 and the driving wheel 272 and prevent the driven gear 274 from rotating randomly. It should be emphasized that the friction between the first friction washer 275 and the outer wall of the driving wheel 272 is much smaller than the friction between the second friction washer 276 and the outer wall of the frame 24, and the driving rack 1023 rotates the driven gear 274 exactly one circle each time it is moved; It should be further emphasized that when the driving rack 1023 descends and drives the driven gear 274 to rotate, it cannot drive the second rotating shaft 271 to rotate, and drives the first friction washer 275 to rotate. Since the friction between the first friction washer 275 and the outer wall of the driving wheel 272 is much smaller than the friction between the second friction washer 276 and the outer wall of the frame 24, the driving wheel 272 remains stable and does not rotate, so only the driven gear 274 rotates. When the driving rack 1023 rises, the driven gear 274 rotates, and the second rotating shaft 271 rotates under the action of the one-way bearing, driving the driving wheel 272 to rotate, so that the second friction washer 276 slides on the frame 24. After the drill body 1022 rises and its drilling end is completely separated from the drilling workpiece, the driving rack 1023 can mesh with the driven gear 274 after the drill body 1022 continues to rise for a certain distance, and then the driving rack 1023 continues to rise to drive the driven gear 274 to drive the second rotating shaft 271 to rotate, thereby driving the driving wheel 272 to rotate, until the driving rack 1023 is separated from the driven gear 274 again, the driven gear 274 rotates one circle, thereby driving the driving wheel 272 to rotate one circle, and the groove wheel 273 is driven to rotate 90 degrees, so that the drilling workpiece placed vertically can be turned 90 degrees to be horizontal, and then the drill body 1022 is lowered again to perform the second drilling work of the lock body, and each time the drill body 1022 is lowered, the driving rack 1023 descends and enters the avoidance hole 221, and the setting of the avoidance hole 221 prevents the moving plate 22 from obstructing the driving rack 1023; The driving assembly 28 includes a first bidirectional screw 281 rotatably connected to the middle of the top surface of the moving plate 22 through a bearing, a threaded sleeve 282 is fixed to the middle of the bottom surface of the frame 24, and the two threaded sleeves 282 above each moving plate 22 are respectively threadedly connected to the two ends of a first bidirectional screw 281 above the moving plate 22, and a first motor 283 is fixed to the top of the moving plate 22, and the output end of the first motor 283 is fixed to the end of the first bidirectional screw 281; When the driving assembly 28 is working, the first motor 283 rotates to drive the first bidirectional screw 281 to rotate, so that the frame frames 24 at both ends of the first bidirectional screw 281 can be moved closer to each other or farther away from each other. When the two frame frames 24 move closer to each other, the clamping blocks 26 move closer to each other to clamp the drilling workpiece. When the two frame frames 24 move away from each other, the two clamping blocks 26 move away from each other to release the clamping work of the drilling workpiece. The moving assembly 3 includes a linear motor 31 fixed on the top of the drilling platform 101, and the moving end of the linear motor 31 is fixed to the outer wall of the two moving plates 22. When the clamping assembly 2 is driven to move, the linear motor 31 drives the two moving plates 22 to move simultaneously, so that the switching of the clamping station 200 can be realized, so that the two clamped workpieces are alternately switched to the drilling station 100; The alignment component 4 includes a telescopic rod 41 slidably mounted on the movable plate 22 through a sliding hole, and a stabilizing sleeve 47 is fixed to the top and bottom of the movable plate 22 at positions corresponding to the telescopic rod 41. The telescopic rod 41 is slidably connected to the inner wall of the stabilizing sleeve 47, and the stabilizing sleeve 47 can make the telescopic rod 41 slide up and down stably on the movable plate 22 without shaking. A push rod 42 is provided on the sliding sleeve on the outer wall of the lower end of the telescopic rod 41, and a spring 43 is inserted in the inner cavity of the push rod 42. One end of the spring 43 is in compression contact with the inner wall of the push rod 42 and the other end is in compression contact with the bottom of the telescopic rod 41. An alignment plate 44 is fixed to the top of the telescopic rod 41, and the alignment plate 44 is located above the first bidirectional screw 281. The alignment plate 44 is located between the two clamping blocks 26 on the movable plate 22. Two guide rail plates 45 arranged in an inclined shape are symmetrically installed on the top of the drilling platform 101. The bottom of the push rod 42 is rotatably connected to a roller 46 through an axle pin, and the roller 46 cooperates with the guide rail plate 45. The function of the alignment component 4 is to receive the drilling workpiece when the movable plate 22 is at one side of the drilling tool body 1022 and not at the drilling station 100, and the drilling workpiece is installed. At this time, the two clamping blocks 26 are arranged longitudinally, and when the drilling workpiece is inserted between the two clamping blocks 26, the drilling workpiece will not leak out from the sides between the two clamping blocks 26. When clamping, it is only necessary to drive the two clamping blocks 26 to move a small distance closer to each other so that they are pressed against the outer wall of the drilling workpiece to complete the clamping work. When the drilling workpiece is inserted, the bottom of the drilling workpiece falls on the top of the alignment plate 44, and the alignment work is completed. Specifically, after the drilling workpiece is installed and follows the moving plate 22 to the drilling station 100 and is clamped, the drilling workpiece is arranged vertically, and its axis can be directly opposite to the drilling end axis of the drilling tool body 1022, that is, the drilling tool body 1022 descends to drill the middle part of the drilling workpiece; The alignment plate 44 can limit the position of the drilling workpiece when the drilling workpiece is installed, that is, when the drilling workpiece is installed, its bottom falls on the top of the alignment plate 44, and the alignment plate 44 limits the position of the drilling workpiece clamped between the clamping blocks 26, ensuring that after the drilling workpiece is turned over by the turning assembly 27, the position on its side wall to be drilled can also face the drilling end axis of the drilling tool body 1022 after turning over; It should be emphasized that, in the process of the movable plate 22 rotating from one side of the drilling tool body 1022 to the bottom of the drilling tool body 1022, the first motor 283 on the movable plate 22 first drives the first bidirectional screw 281 to rotate and clamp the drilling workpiece, and then the movable plate 22 moves to the side close to the drilling station 100. During the movement, the roller 46 under the movable plate 22 rolls along the guide plate 45, so that the alignment plate 44, the push rod 42 and the telescopic rod 41 assembly are lowered, and at the same time, they will move with the movable plate 22 until the movable plate 22 moves to the drilling station 100, the alignment telescopic rod 41, the push rod 42 and the alignment plate 44 are lowered to the lowest position. Since the alignment plate 44 is lowered, it will not hinder the flipping of the drilling workpiece, and after two drillings, the drilling workpiece is flipped 180 degrees downward, and then the movable plate 22 at the drilling station 100 is driven to move to one side. During this movement, the roller 46 can be pushed upward by the guide plate 45. The roller 46 rolls on it, so that the push rod 42 can move upward and also translate with the moving plate 22 until it moves to the alignment plate 44 and is pressed against the bottom of the drilling workpiece, and the alignment plate 44 no longer moves upward. Then, during the process that the moving plate 22 continues to move to one side, the roller 46 is acted upon by the guide plate 45 to continue to drive the push rod 42 to move upward. During this process, the telescopic rod 41 no longer moves upward and can compress the spring 43, and finally the moving plate 22 moves to one side, and the other moving plate 22 moves to the drilling station 100, and then drives the first motor 283 to work, so that the workpiece not on the drilling station 100 is released from the clamping. It should be emphasized that before releasing the clamping, the workpiece needs to be manually blocked by the two clamping blocks 26 to prevent the spring 43 from quickly rebounding and bouncing off the drilling workpiece. After the clamping is released and the drilling workpiece is removed, the spring 43 is reset, so that the telescopic rod 41 returns to the uppermost position on the push rod 42, and then the two clamping blocks 26 on this side continue to install new clamping workpieces. In summary, the specific use process of the entire device is as follows: 1. First, insert the drilling workpiece between the two clamping blocks 26 on the moving plate 22 on the non-drilling station 100, and the drilling workpiece falls on the alignment plate 44. It should be emphasized that the elastic force of the spring 43 is sufficient to support the drilling workpiece, that is, the drilling workpiece is placed on the alignment plate 44, and the spring 43 cannot be deformed, and the alignment plate 44 cannot be lowered, and then the clamping assembly 2 is driven to clamp the drilling workpiece. During this process, drilling work is being performed on the drilling station 100; 2. When the drilling of the workpiece on the movable plate 22 on the drilling station 100 is completed, the movable assembly 3 drives the two movable plates 22 to move simultaneously, so that the workpiece after drilling is moved away from the drilling station 100, and the newly loaded workpiece is moved to the drilling station 100. During the movement, the push rod 42, the telescopic rod 41 and the alignment plate 44 below the newly loaded workpiece are lowered under the action of the guide plate 45 until the newly loaded workpiece moves to the drilling station 100, and the push rod 42, the telescopic rod 41 and the alignment plate 44 below the newly loaded workpiece are lowered to the lowest position; 3. The lifting assembly 1021 drives the drilling tool body 1022 to descend to perform drilling work, and if Fig. 9 As shown, after the driving rack 1023 is meshed and separated from the driven gear 274, the drill body 1022 continues to descend a certain distance so that its drilling end can enter the lock pin drilling workpiece. After one drilling is completed, the drill body 1022 rises, and the driving rack 1023 rises to turn the driven gear 274 to make the drilled workpiece flip 90 degrees. Then the drill body 1022 continues to descend for the second drilling. After the drilling is completed, the drill body 1022 continues to rise until the driving rack 1023 rises to the uppermost end. After the two drillings, the drilled workpiece will be flipped 180 degrees to face downward. 4. The moving assembly 3 drives the moving plate 22 to move and continue to switch the clamping station 200, so that the drilled workpiece after drilling is moved to one side and leaves the drilling station 100. During the movement, the guide plate 45 pushes the push rod 42 and the telescopic rod 41 to move upward. However, since the drilled workpiece is turned downward, the alignment plate 44 is pressed against the bottom of the drilled workpiece, and the telescopic rod 41 will not continue to move upward, while the moving plate 22 continues to move to one side. At the same time, the push rod 42 continues to move to one side and rises, thereby compressing the spring 43. 5. Until the drilling workpiece reaches one side and the movement is completed, the person holds the drilling workpiece by hand, and then drives the clamping assembly 2 to release the clamping work, takes away the drilling workpiece, and the spring 43 pushes the telescopic rod 41 to rise and reset to its highest position on the top rod 42, and then loads a new drilling workpiece, and repeats the above steps to continue the workpiece loading and drilling work.

[0020] For example 2, please refer to Fig.12 and Fig.13The guide plate 45 is rotatably connected to the drilling platform 101 through an axle pin. An angle adjustment assembly 5 for simultaneously adjusting the inclination angles of the two guide plates 45 is also installed on the drilling platform 101. The angle adjustment assembly 5 includes a sink 51 provided on the top of the drilling platform 101. The inner wall of the sink 51 is rotatably connected to a second bidirectional screw 52 through a bearing. Both ends of the second bidirectional screw 52 are symmetrically threadedly connected to moving blocks 53. The moving block 53 is slidably connected to the inner wall of the sink 51. The top of the moving block 53 is rotatably connected to a flip bar 54 through an axle pin. The upper ends of the two flip bars 54 are rotatably connected to the outer walls of the two guide plates 45 through axle pins, and a knob 55 is fixed to one end of the second bidirectional screw 52. The sizes of lock bodies of different batches are different, which are specifically manifested in different diameters and heights and different second drilling positions of the side walls. The different diameters can be achieved by controlling the distance between the two clamping blocks 26. When the height of the drilling workpiece changes or the second drilling position of its side wall changes, the height of the alignment plate 44 can be adjusted by adjusting the inclination angle of the guide plate 45, that is, it can adapt to this situation. By adjusting the height of the alignment plate 44, it can be ensured that the drilling workpieces with various height requirements or different second drilling position requirements of the side wall are placed between the two clamping blocks 26 and carried on the alignment plate 44. By adjusting the height of the alignment plate 44, it can be ensured that after the clamping block 26 is clamped and turned 90 degrees, the position of the side wall that needs to be drilled again can be aligned with the axis of the drilling end of the drilling tool body 1022. The specific principle is that the drilling workpiece with the bottom mounted on the alignment plate 44 is longitudinally inserted between the clamping blocks 26. By adjusting the height of the alignment plate 44, it is ensured that the axis of the hole drilled twice on the side wall of the drilling workpiece in the vertical state can be perpendicular to the axis of the first rotating shaft 25. In this way, it can be ensured that after the drilling workpiece is clamped and turned 90 degrees to be horizontal, the position of the secondary drilling on the side wall can be aligned with the axis of the drilling end of the drilling tool body 1022. The specific adjustment process is to rotate the knob 55 to drive the second bidirectional screw 52 to rotate, thereby driving the two moving blocks 53 to move closer to or away from each other, so as to push the flip bar 54, thereby adjusting the inclination angle of the guide plate 45.

[0021] In summary, the present invention can complete the two drilling work of the lock pin of the lock body on one device, and the two drilling work only requires one clamping of the drilling workpiece, and there is no need to repeatedly disassemble and assemble the drilling workpiece twice, which greatly improves the drilling production efficiency of the lock body and reduces the manual operation steps. At the same time, due to the provision of the alignment component 4, it can assist workers to quickly position the drilling workpiece without manual positioning. During installation, workers only need to put the drilling workpiece between the two clamping blocks 26, and then the clamping blocks 26 clamp the drilling workpiece, which can ensure that the first drilling position and the second drilling position of the drilling workpiece can be aligned with the drilling end of the drill body 1022, further reducing the labor intensity of manual labor. At the same time, the angle adjustment component 5 is provided so that the height of the alignment plate 44 can be adjusted, so that the entire device can adapt to the drilling work of drilling workpieces of various heights and diameters and the drilling work required by different secondary drilling positions on the drilling workpiece.
