Description

Technical Field

[0001] The invention relates to the technical field of lock drilling, in particular to an automatic drilling processing device for a lock precision component. Background Art

[0002] Lock precision components refer to the various fine parts that make up the lock. These parts usually have high processing accuracy requirements to ensure the reliability and safety of the lock. The design and manufacture of lock precision components involve a variety of technologies and processes; the lock core is the core part of the lock, which is responsible for cooperating with the key to achieve the functions of unlocking and locking; for the lock core in the padlock, it is generally necessary to first drill the key slot hole at the bottom of the lock core, and then drill multiple side holes connected to the unlocking hole on both sides of the lock core in turn, which are used for the subsequent assembly of small cylindrical parts, and lock or unlock by cooperating with the key slot hole.

[0003] The existing method of drilling the side holes of the lock core is to drill the holes one by one individually. Although this method can complete the drilling process, the overall time consumption of multiple drillings is relatively long.

[0034] The lock core with the key slot hole drilled at the bottom is placed on the rectangular matching block 2. The rectangular matching block 2 in the initial state is located at the rear side of the limiting groove 14. At this time, the upper and lower limit plates 41 are at the maximum distance. The upper and lower limit plates 41 move synchronously to the center until the bottom end of the placement plate 13 and the lock core are in a relatively static state. The lock core is further limited and fixed, and the drilling mechanisms 3 on the left and right sides are started. The two sides of the lock core will be drilled synchronously. After the side drilling operation is completed, the upper and lower limit plates 41 will be removed to fix the lock core, and the lock core will be fixed. The lock core is taken out. 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 shake up and down to a certain extent, and the debris generated during the drilling operation will slide out along the inclined chip guide groove 15. At the same time, the rectangular matching block 2 is moved from the rear side to the front side of the limiting groove 14, and the rotating gear 25 is driven to rotate 90 degrees through the rotating component 26, which synchronously drives the rectangular matching block 2 to rotate 90 degrees, and the lock core is placed on the rectangular matching block 2 again, and the self-cleaning component 22 is started to clean the multiple side holes of the lock core.

[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.

The rotating gear 25 does not contact the driving rack rod 262, and at this time, the lower part of the rectangular matching block 2 is clamped in the limiting groove 14, and the limiting groove 14 plays a certain limiting role on the rectangular matching block 2. When it is necessary to rotate the rectangular matching block 2, the first electric telescopic rod is started first, and the supporting slide bar 24 is pushed to move upward, and the rotating gear 25 will contact and mesh with the driving rack rod 262. At this time, the rectangular matching block 2 is located above the limiting groove 14, and the rectangular matching block 2 is no longer limited to the limiting groove 14.
