Description

Technical Field

[0001] The present invention relates to the technical field of lock drilling, and specifically relates to an automatic drilling processing device for precision components of locks. Background Art

[0002] Precision components of locks refer to various fine parts that make up the locks. These parts usually have high machining accuracy requirements to ensure the reliability and safety of the locks. The design and manufacture of precision components of locks involve multiple technologies and processes; among them, the lock core is the core part of the lock, responsible for cooperating with the key to achieve the functions of unlocking and locking; for the lock core in a padlock, generally, a key slot hole needs to be drilled at the bottom of the lock core first, and then a plurality of side holes communicating with the unlocking hole are drilled in sequence on both sides of the lock core for subsequent assembly of small cylindrical components, and the lock or unlock is achieved through the cooperation with the key slot hole.

[0003] The existing drilling of the side holes of the lock core is carried out one by one in a separate manner. Although this method can complete the drilling processing operation, the overall time consumption of multiple drillings is relatively long. Moreover, during the drilling process of the lock core, due to the unilateral force, the clamping stability requirement for the lock core is relatively high, and the accuracy of the lock core drilling cannot be ensured.

[0004] After the lock core is drilled, due to the electrostatic reaction generated by the debris, some debris is likely to adhere to the inner wall of the side hole. The existing blowing method of cleaning cannot completely clean it, which affects the subsequent installation of other components on the lock core. Summary of the Invention

Detailed implementation manners

[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 , Figure 2 and Figure 7 , an automatic drilling processing device for precision components of a lock, including an L-shaped base 1. A fixed base 11 is fixedly connected to the middle of the horizontal section of the L-shaped base 1. A placement groove is opened at the upper end of the fixed base 11. A spring telescopic rod 12 is fixedly connected inside the placement groove. The top end of the spring telescopic rod 12 is fixedly connected to a placement plate 13. A limit groove 14 is opened at the upper end of the placement plate 13. A rectangular fitting block 2 for internally supporting the lock core is arranged inside the limit groove 14. Arc-shaped grooves 21 are opened on the left and right sides of the rectangular fitting block 2. A receiving groove is opened at the bottom end of the rectangular fitting block 2. A self-cleaning component 22 is arranged inside the receiving groove. Docking through holes 23 communicating with the receiving groove are opened at the front and back of the rectangular fitting block 2. A support sliding rod 24 is fixedly connected to the bottom end of the rectangular fitting block 2. A rotating gear 25 is fixedly connected to the support sliding rod 24. A rotating component 26 for driving the rotation of the rotating gear 25 is arranged at the frontmost side of the limit groove 14.

[0033] Continue to refer to Figure 1 , a drilling mechanism 3, arranged on the left and right sides of the vertical section of the L-shaped base 1, for synchronously drilling the lock core. Among them, the drilling mechanism 3 includes a sliding groove 31 opened on the front side of the vertical section of the L-shaped base 1. A drilling machine mounting block 32 is slidably arranged inside the sliding groove 31. A plurality of drill bits are arranged on the opposite sides of the left and right two drilling machine mounting blocks 32. A drilling synchronous driving mechanism 33 is arranged on the opposite back sides of the two drilling machine mounting blocks 32; a limiting mechanism 4, arranged on the upper and lower sides of the vertical section of the L-shaped base 1, and located on the upper and lower sides of the limit groove 14, for further limiting and fixing the placed lock core; the limiting mechanism 4 includes two upper and lower groups of limiting plates 41, and each group of limiting plates 41 consists of two left and right ones.

[0034] Place the lock core with the bottom key slot hole already drilled on the rectangular fitting block 2. In the initial state, the rectangular fitting block 2 is located at the rearmost side of the limit groove 14. At this time, the upper and lower groups of limit plates 41 are in the state of the maximum distance. The upper and lower groups of limit plates 41 move synchronously and centrally until the bottom end of the placement plate 13 and the lock core are in a relatively static state, further limiting and fixing the lock core. Start the drilling mechanisms 3 on both the left and right sides, and synchronous drilling operations will be performed on both sides of the lock core. After the side drilling operation is completed, release the fixation of the lock core by the upper and lower limit plates 41 and take out the lock core. Since the placement plate 13 is elastically connected by the spring telescopic rod 12, when the lock core is taken out, the placement plate 13 will vibrate up and down to a certain extent. The debris generated during the drilling operation will slide out along the inclined chip guide groove 15. At the same time, move the rectangular fitting block 2 from the rear side to the front side of the limit groove 14, and drive the rotating gear 25 to rotate 90 degrees through the rotating assembly 26, synchronously driving the rectangular fitting block 2 to rotate 90 degrees. Place the lock core on the rectangular fitting block 2 again, and start the self-cleaning assembly 22 to perform cleaning operations on multiple side holes of the lock core.

[0035] Refer to Figure 6 , the self-cleaning assembly 22 includes a micro blower 221 fixedly connected to the bottom end of the accommodation groove. The upper end of the micro blower 221 is fixedly connected with a fixed support rod 222 through a connecting rod. The fixed support rod 222 is arranged inside the main airbag 223, and the bottom end of the main airbag 223 is communicated with the inflation port of the micro blower 221. A plurality of side airbags 224 are communicated on both sides of the main airbag 223. The side airbags 224 correspond to the positions of the docking through holes 23 one by one. The side away from the main airbag 223 of the side airbag 224 is an arc structure, and a flexible rubber protrusion is fixedly connected to the outside of the side airbag 224.

[0036] Continue to refer to Figure 6 , an adsorption magnet 225 is fixedly connected to the arc-shaped side of the side airbag 224. Electromagnets 226 are arranged on both sides of the fixed support rod 222 corresponding to the positions of the side airbags 224. An elastic rope is fixedly connected between the adsorption magnet 225 and the electromagnet 226.

[0037] The self-cleaning component 22 is set to perform self-cleaning operation on the lock core after the drilling operation. The docking through holes 23 on the rectangular matching block 2 correspond to the drilled holes on both sides of the lock core. In the initial state, multiple electromagnets 226 are in a powered state, and the electromagnets 226 and the adsorption magnets 225 are adsorbed on each other. The micro-blower 221 is started to fill the main airbag 223 with air first. At the same time, the side airbag 224 connected to the main airbag 223 will move along the docking through hole 23 toward the side hole of the lock core. The flexible rubber protrusions on the outside of the side airbag 224 will drive the debris in the side hole of the lock core to push outward to clean the side hole. At this time, the elastic rope is in a stretched state. When the side airbag 2 One side of the arc 24 passes through the outside of the side hole of the lock core, and the placement plate 13 is pushed by external force. The placement plate 13 shakes up and down again under the action of the spring telescopic rod 12, and the debris adhered to the flexible rubber protrusions on the side airbag 224 will be shaken off. When the side airbag 224 is cleaned, the main airbag 223 and the side airbag 224 are deflated first. The elastic rope will drive the adsorption magnet 225 to move towards the direction close to the main airbag 223 under the action of its own elastic contraction, reducing the distance between the electromagnet 226 and the adsorption magnet 225, and the electromagnet 226 is energized, and the adsorption magnet 225 and the electromagnet 226 are adsorbed for the next cleaning operation.

[0038] See also Figure 4 and Figure 5 The upper end of the placement plate 13 and the left and right sides of the limiting groove 14 are provided with inclined chip guide grooves 15, and the bottom end of the limiting groove 14 is provided with a placement circular groove 16. The bottom end of the placement circular groove 16 is fixedly connected with a first electric telescopic rod, and the upper end of the first electric telescopic rod is rotatably connected to the bottom end of the supporting slide bar 24. The height of the placement circular groove 16 is higher than the height of the supporting slide bar 24.

[0039] See also Figure 5 The rotating assembly 26 includes a rectangular through groove 261 connected to the front side of the limiting groove 14, and the rectangular through groove 261 is connected to the upper part of the circular groove 16. A driving rack rod 262 is slidably connected in the rectangular through groove 261, and a second electric telescopic rod 263 is fixedly connected to one side of the driving rack rod 262. The second electric telescopic rod 263 is fixedly connected to one side of the rectangular through groove 261 through a mounting seat.

[0040] The rotation assembly 26 is provided to drive the rectangular mating block 2 to rotate 90 degrees each time. When it is necessary to limit the rectangular mating block 2, the first electric telescopic rod is in a contracted state, the support slide rod 24 drives the rotation gear 25 to be at the bottom of the placement circular groove 16, the rotation gear 25 is not in contact with the driving rack bar 262, and at this time the lower part of the rectangular mating block 2 is clamped in the limit groove 14, and the limit groove 14 plays a certain limiting role on the rectangular mating block 2. When it is necessary to rotate the rectangular mating block 2, first start the first electric telescopic rod to push the support slide rod 24 upward, and the rotation gear 25 will contact and mesh with the driving rack bar 262. At this time, the rectangular mating block 2 is located above the limit groove 14, and the rectangular mating block 2 no longer limits the limit groove 14. Then start the second electric telescopic rod 263 to push the driving rack bar 262 to one side. The driving rack bar 262 meshes with and rotates the rotation gear 25, driving the rotation gear 25 to rotate 90 degrees, and further driving the rectangular mating block 2 to rotate 90 degrees.

[0041] Participate Figure 2 , the drilling synchronous drive mechanism 33 includes L-shaped connecting frames 331 fixedly connected to the opposite sides of the two drill mounting blocks 32. The left and right L-shaped connecting frames 331 are located at different upper and lower heights of the drill mounting blocks 32 respectively. Moving racks 332 are fixedly connected to the rear sides of the L-shaped connecting frames 331, and a driving gear 333 is meshed and connected in the middle of the upper and lower moving racks 332.

[0042] The setting of the drilling synchronous drive mechanism 33 is to synchronously drill the side holes on both sides of the lock core. An external motor (not shown specifically in the figure) is provided on the driving gear 333. During specific operation, start the external motor to drive the driving gear 333 to rotate. The driving gear 333 will synchronously drive the upper and lower moving racks 332 to move, and the moving racks 332 drive the L-shaped connecting frames 331 to push the sliding groove 31 towards the lock core.

[0043] Refer to Figure 1 , the limiting mechanism 4 further includes two groups of vertical grooves 42, each group of vertical grooves 42 consists of two left and right ones. U-shaped fixing rods 43 are fixedly connected to the rear ends of each group of limiting plates 41 together. Rubber pads are provided on the side close to each other and the bottom side of the upper two limiting plates 41. The front sides of the U-shaped fixing rods 43 slide through the vertical grooves 42, and a limiting drive assembly 44 is provided on the upper and lower U-shaped fixing rods 43.

[0044] Refer to Figure 2, the limit driving assembly 44 includes threaded holes and sliding holes formed in two U-shaped fixing rods 43. A guiding rod 441 is commonly connected in the sliding holes of the upper and lower U-shaped fixing rods 43. The guiding rod 441 is fixedly connected to the rear side of the L-shaped seat 1 through a bracket.

One end of the bidirectional threaded rod 442 is fixedly connected to a motor, and the motor is fixedly connected to the rear side of the L-shaped seat 1 through a motor seat. The other end of the bidirectional threaded rod 442 is rotatably connected to a support, and the support is fixedly connected to the rear side of the L-shaped seat 1.

[0045] The limit mechanism 4 is provided to limit and fix the lock core of the drill. Start the motor on the bidirectional threaded rod 442. The bidirectional threaded rod 442 drives the upper and lower U-shaped fixing rods 43 to move closer. The guiding rod 441 limits the movement of the upper and lower U-shaped fixing rods 43. The U-shaped fixing rods 43 drive the upper and lower groups of limit plates 41 to fix the lock core. Since the upper limit plate 41 directly contacts the lock core, the provided rubber pad avoids damaging the lock core.
