Technical Field
[0001] This utility model relates to the field of lock processing equipment technology, and in particular to a lock cylinder processing equipment. Background Technology
[0002] The lock cylinder is the core component of a lock, responsible for controlling its opening. It employs multiple anti-theft technologies, including various irregularly shaped anti-picking pins and a precision numbered pin structure, providing high security against technical unlocking. The lock cylinder, through its multiple combinations of irregularly shaped pins, can program billions of key combinations, achieving zero cross-keying within a given area. Furthermore, the lock cylinder incorporates a lateral inward-pressing side pin locking device, enhancing its ability to prevent forced twisting.
[0003] The processing steps for lock cylinder shells typically include drilling, chamfering, tapping, corner setting, and polishing. Currently, there are two methods for switching between these workstations: the first is manual switching by workers, which is extremely inefficient; the second is switching using a robotic arm. The robotic arm first transports the lock cylinder shell to the drilling station, where a drilling machine drills a hole. Then, the robotic arm transports the lock cylinder shell to the chamfering station, where a chamfering machine polishes the burr-covered end of the newly machined hole. The lock cylinder shell is chamfered and then transported to the tapping station by a robotic arm. The tapping machine taps the holes on the lock cylinder shell to create threads. The robotic arm then transports the lock cylinder shell to the corner step station, where a drilling machine performs corner step treatment on both ends of the lock cylinder. Finally, the robotic arm transports the lock cylinder shell to the grinding station, where a grinding machine grinds both ends of the lock cylinder shell. Since one lock cylinder shell must be processed before the next lock cylinder shell can be processed, the processing efficiency is still low and it is difficult to handle the processing of large batches of lock cylinder shells. Utility Model Content
[0004] The purpose of this invention is to provide a lock cylinder processing equipment that can significantly improve the processing efficiency of lock cylinder shells, facilitate the processing and production of large-scale products, and thus bring good economic benefits to enterprises.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lock cylinder processing equipment, comprising a processing platform and a reciprocating conveying mechanism. The processing platform, extending in a specific direction, is sequentially provided with a drilling positioning seat, a chamfering positioning seat, a tap positioning seat, a corner step positioning seat, a grinding positioning seat, and a discharge station for positioning the lock cylinder shell. The drilling positioning seat is connected to a conveying track for transporting the lock cylinder shell. A first drilling machine is positioned on the side of the processing platform corresponding to the drilling positioning seat. A chamfering machine is positioned on each side of the processing platform corresponding to the chamfering positioning seat. A tapping machine is positioned on one side of the processing platform corresponding to the tap positioning seat. A second drilling machine is positioned on each side of the processing platform corresponding to the corner step station. A grinding machine is positioned on each side of the processing platform corresponding to the grinding positioning seat. The reciprocating conveying mechanism simultaneously and reciprocally transports the lock cylinder shell from the drilling positioning seat, chamfering positioning seat, tap positioning seat, corner step positioning seat, and grinding positioning seat to the chamfering positioning seat, tap positioning seat, corner step positioning seat, grinding positioning seat, and discharge station.
[0006] By adopting the above technical solution, the lock cylinder shell is transported by the transmission track to the drilling positioning seat for drilling. Then, the reciprocating conveying assembly transports the lock cylinder shells on the drilling positioning seat one by one to the chamfering positioning seat for chamfering, to the tapping positioning seat for tapping, to the corner step positioning seat for corner step treatment, to the grinding positioning seat for grinding, and to the unloading station for unloading. Moreover, only one reciprocating conveying mechanism is needed to transport five adjacent lock cylinder shells. This ensures that there are always lock cylinder shells being processed at the drilling positioning seat, chamfering positioning seat, tapping positioning seat, corner step positioning seat, and grinding positioning seat, achieving uninterrupted processing. This can significantly improve the processing efficiency of lock cylinder shells, which is beneficial for the processing and production of large-scale products, thereby bringing good economic benefits to enterprises.
[0007] The present invention is further configured such that the reciprocating conveying mechanism includes a bracket, a horizontal electric slide table disposed on the bracket, a vertical electric slide table disposed on the movable end of the horizontal electric slide table, and five sets of gripping components disposed on the movable end of the vertical electric slide table for gripping the lock cylinder shell.
[0008] By adopting the above technical solution, the horizontal electric slide and the vertical electric slide work together to grasp the component housing to achieve the "down (grab)-up-right-down (release)-up-left" action. The reciprocating action enables the five lock cylinders to move simultaneously and perform corresponding processing.
[0009] The present invention is further configured such that the gripping component includes a fixed frame mounted on the movable end of a vertical electric slide, a finger cylinder mounted on the fixed frame, and a push rod mounted on the two movable ends of the finger cylinder.
[0010] By adopting the above technical solution, the finger cylinder drives the two push rods to move closer or further apart. The lock cylinder shell can be gripped by clamping the two push rods, or the lock cylinder shell can be gripped by pressing against the inner wall of the lock cylinder shell groove.
[0011] The present invention is further configured such that a rotating component is provided between the fixing frame of at least one set of gripping components and the finger cylinder, and the rotating component drives the finger cylinder to rotate.
[0012] By adopting the above technical solution, the grasped lock cylinder shell can be rotated to meet the processing requirements of different parts.
[0013] The present invention is further configured such that the rotating component is a rotary cylinder or a motor.
[0014] By adopting the above technical solutions, the rotary cylinder has the advantages of fast response speed, high efficiency and lower cost, while the motor has the advantages of more flexible control, higher precision and simpler system structure.
[0015] The present invention is further configured such that the drilling positioning seat, the chamfering positioning seat, the tap positioning seat, the corner step positioning seat, and the grinding positioning seat are respectively provided with a first positioning groove, a second positioning groove, a third positioning groove, a fourth positioning groove, and a fifth positioning groove for embedding the lock cylinder shell.
[0016] By adopting the above technical solution, it is beneficial to position the lock cylinder shell on each positioning seat, thereby achieving stable and precise processing of the lock cylinder shell.
[0017] The present invention is further configured such that the drilling positioning seat is provided with a limiting component, the limiting component including a limiting block disposed on the drilling positioning seat and a limiting screw threadedly connected to the limiting block, and when the limiting screw is rotated, the limiting screw moves toward the end of the first positioning groove.
[0018] By adopting the above technical solution, the travel limit component can be used to limit the lock cylinder shell transported to the first positioning slot of the drilling positioning seat, so that after drilling is completed, the reciprocating conveying mechanism can grab the lock cylinder shell and accurately place it on the corresponding positioning seat for processing. Moreover, the position can be adjusted according to the specifications of the lock cylinder shell, that is, by rotating the limit screw, which is very convenient to operate.
[0019] The present invention is further configured such that a preload nut is threadedly connected to the limiting screw, and the preload nut abuts against the drilling positioning seat.
[0020] By adopting the above technical solution and tightening the preload nut, the thread friction of the limit screw can be increased, making the limit screw less prone to loosening and ensuring that it always stays in one position, making its limit adjustment more accurate and reliable.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example: As attached Figures 1-3The lock cylinder processing equipment shown includes a processing platform 1 and a reciprocating conveying mechanism 2. The processing platform 1 has, in its extending direction, a drilling positioning seat 3, a chamfering positioning seat 4, a tap positioning seat 5, a corner step positioning seat 6, a grinding positioning seat 7, and a discharge station 31 for positioning the lock cylinder shell. The discharge station 31 is the discharge position and can be equipped with a discharge conveyor belt or a robotic arm to transport the processed lock cylinder shell to the target position. Each positioning seat is connected to the processing platform 1 by screws. The drilling positioning seat 3 is connected to a transmission rail 8 for transporting the lock cylinder shell. The lock cylinder shell in the transmission rail 8 can be pushed into the drilling positioning seat 3 by a cylinder, hydraulic cylinder, or electric telescopic rod. A first drilling machine 9 is located on the side of the processing platform 1 corresponding to the drilling positioning seat 3. A chamfering machine 10 is located on each side of the processing platform 1 corresponding to the chamfering positioning seat 4. A tapping machine 11 is provided on one side of the processing platform 1 corresponding to the tap positioning seat 5. A second drilling machine 12 is provided on both sides of the processing platform 1 corresponding to the corner step station. A grinding machine 13 (a belt grinding machine 13 is used in this embodiment) is provided on both sides of the processing platform 1 corresponding to the grinding positioning seat 7. The first drilling machine 9, chamfering machine 10, tapping machine 11, second drilling machine 12 and grinding machine 13 are all commercially available mass-produced parts. Therefore, their specific structures are not described in detail here, and their specifications can be selected according to design needs. The reciprocating conveying mechanism 2 is used to simultaneously and reciprocally transport the lock core shell on the drilling positioning seat 3, chamfering positioning seat 4, tapping positioning seat 5, corner step positioning seat 6 and grinding positioning seat 7 to the chamfering positioning seat 4, tapping positioning seat 5, corner step positioning seat 6, grinding positioning seat 7 and the discharge station 31. The lock cylinder shell is transported by the transmission track 8 to the drilling positioning seat 3 for drilling. Then, the reciprocating conveying assembly transports the lock cylinder shells on the drilling positioning seat 3 one by one to the chamfering positioning seat 4 for chamfering, to the tapping positioning seat 5 for tapping, to the corner step positioning seat 6 for corner step treatment, to the grinding positioning seat 7 for grinding, and to the unloading station 31 for unloading. Only one reciprocating conveying mechanism 2 is needed to transport five adjacent lock cylinder shells. This ensures that there are always lock cylinder shells being processed at the drilling positioning seat 3, chamfering positioning seat 4, tapping positioning seat 5, corner step positioning seat 6, and grinding positioning seat 7, achieving uninterrupted processing. This significantly improves the processing efficiency of lock cylinder shells, which is beneficial for the processing and production of large-scale products, thereby bringing good economic benefits to the enterprise.
[0027] As attached Figure 1 and attached Figure 2As shown, the reciprocating conveying mechanism 2 includes a bracket 14, a horizontal electric slide 15 mounted on the bracket 14, a vertical electric slide 16 mounted on the movable end of the horizontal electric slide 15, and five sets of gripping components 17 mounted on the movable end of the vertical electric slide 16 for gripping lock cylinder shells. The horizontal electric slide 15 and the vertical electric slide 16, in conjunction with the gripping components 17, achieve a "down (grip) - up - right - down (release) - up - left" motion. This reciprocating motion allows the five lock cylinders to move simultaneously and undergo corresponding processing.
[0028] As attached Figure 1 and attached Figure 2 As shown, the gripping assembly 17 includes a fixed frame 18 mounted on the movable end of the vertical electric slide 16, a finger cylinder 19 mounted on the fixed frame 18, and push rods 20 mounted on the two movable ends of the finger cylinder 19. The finger cylinder 19 drives the two push rods 20 to move closer to or further away from each other. The two push rods 20 can clamp the lock cylinder shell to grip it, or they can press against the inner wall of the lock cylinder shell groove to grip it.
[0029] As attached Figure 1 and attached Figure 2 As shown, at least one set of gripping components 17 has a rotating member 21 between its fixing frame 18 and finger cylinder 19, and the rotating member 21 drives the finger cylinder 19 to rotate. This allows for rotation of the gripped lock cylinder shell, satisfying the processing requirements of different parts of it.
[0030] The rotating component 21 can be a rotary cylinder or a motor. Rotary cylinders have the advantages of fast response, high efficiency, and lower cost, while motors have the advantages of more flexible control, higher precision, and simpler system structure.
[0031] As attached Figure 1 As shown, the drilling positioning seat 3, chamfering positioning seat 4, tap positioning seat 5, corner step positioning seat 6, and grinding positioning seat 7 are respectively provided with a first positioning groove 22, a second positioning groove 23, a third positioning groove 24, a fourth positioning groove 25, and a fifth positioning groove 26 for the insertion of the lock cylinder shell. This design facilitates the positioning of the lock cylinder shell on each positioning seat, thereby achieving stable and precise machining of the lock cylinder shell.
[0032] In this embodiment, as shown in the appendix Figure 1 As shown, the first positioning groove 22, the second positioning groove 23 and the third positioning groove 24 are all arranged horizontally, and the fourth positioning groove 25 and the fifth positioning groove 26 are arranged vertically. Therefore, when the lock cylinder shell is transported between the third positioning groove 24 and the fourth positioning groove 25, the angle needs to be rotated by 90°. Therefore, the aforementioned rotating component 21 is set on the third group of gripping components 17 from left to right.
[0033] Through holes or clearance slots can be opened on the corresponding positioning seats to connect with the corresponding positioning slots, so that the corresponding cutting tools can be inserted to process the lock cylinder shell. This structure can be set according to actual processing needs.
[0034] As attached Figure 1 and attached Figure 3 As shown, the drilling positioning base 3 is equipped with a limiting component 27. The limiting component 27 includes a limiting block 28 connected to the drilling positioning base 3 by screws and a limiting screw 29 threadedly connected to the limiting block 28. Specifically, the limiting block 28 has a threaded hole, and the limiting screw 29 is threaded into the threaded hole. When the limiting screw 29 is rotated, it moves towards or away from the end of the first positioning groove 22. The limiting component 27 can limit the travel of the lock cylinder shell transported to the first positioning groove 22 of the drilling positioning base 3, so that after drilling is completed, the reciprocating conveying mechanism 2 can grasp the lock cylinder shell and accurately place it on the corresponding positioning base for processing. Moreover, this position can be adjusted according to the specifications of the lock cylinder shell, that is, by rotating the limiting screw 29, which is very convenient to operate.
[0035] As attached Figure 3 As shown, a preload nut 30 is also threaded onto the limiting screw 29, and the preload nut 30 abuts against the drilling positioning seat 3. Tightening the preload nut 30 increases the thread friction of the limiting screw 29, thereby making the limiting screw 29 less prone to loosening and ensuring that it always stays in one position, making its limiting adjustment more precise and reliable.
