Description

Technical Field

[0001] This disclosure relates to the technical field of lock tapping, and in particular to a rotary lock tapping machine. Background Technology

[0002] In the lock manufacturing industry, the tapping process is a crucial step, as its precision and efficiency directly impact the quality and production efficiency of locks. Traditional lock tapping methods often employ a single tapping pattern. This pattern requires removing the lock from its processing position and readjusting it before the next tapping operation. This increases the number of steps and processing time, reducing the number of locks produced per unit time and resulting in low overall production efficiency. Furthermore, during the repositioning process, inaccurate positioning can easily lead to tapping deviations, affecting the relative positional accuracy between different threads on the lock. This, in turn, reduces the assembly precision and stability of the lock's components, ultimately lowering the overall lock quality. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] like Figures 1 to 5 As shown, a rotary lock tapping machine 10 according to an embodiment of the present disclosure includes a frame 100, a lifting structure 200, a tapping structure 300, a rotary feeding structure 400, a clamping and fixing structure 500, and a plurality of clamping structures 600. The tapping structure 300 is connected to the power output end of the lifting structure 200. The lifting structure 200, the rotary feeding structure 400, and the clamping and fixing structure 500 are respectively fixedly connected to the frame 100. The clamping and fixing structure 500 is disposed between the lifting structure 200 and the rotary feeding structure 400.

[0030] The tapping structure 300 includes a split connector 310 and two tap assemblies 320. Both tap assemblies 320 are connected to the split connector 310. The two tap assemblies 320 are symmetrically arranged along the center line of the split connector 310. The turntable feeding structure 400 includes a rotating motor assembly 410 and a clamping rotating disk 420. The clamping rotating disk 420 is connected to the power output end of the rotating motor assembly 410. Multiple clamping structures 600 are spaced apart on the clamping rotating disk 420. The clamping end of the clamping and fixing structure 500 abuts against one of the clamping structures 600. The clamping end of the clamping and fixing structure 500 is located between two tap assemblies 320.

[0031] In this embodiment, during the operation of the rotary lock tapping machine 10, the rotating motor assembly 410 of the rotary feeding structure 400 starts to operate, driving the clamping rotary disk 420 to rotate. After the clamping rotary disk 420 rotates a certain angle, one of the clamping structures 600 containing the lock is conveyed to the area below the clamping end of the clamping and fixing structure 500. At this time, the clamping end of the clamping and fixing structure 500 abuts against the clamping structure 600 below to achieve stable fixing of the lock. Since the clamping end of the clamping and fixing structure 500 is located between the two tap assemblies 320, the lock, after being fixed, can be exactly within the tapping range of the two tap assemblies 320.

[0032] Furthermore, after the lock is accurately secured, the lifting structure 200 begins to operate. Its power output drives the tapping structure 300 downward. Since both tap assemblies 320 are connected to the taper connector 310 and are symmetrically arranged, the two tap assemblies 320 will move downward synchronously with the lifting structure 200 and simultaneously contact the secured lock. At this time, the two tap assemblies 320 begin tapping the lock.

[0033] Specifically, in traditional single-tapping methods, the lock needs to be repositioned after each tapping operation before the next tapping can begin. This not only increases the number of steps and time involved but also makes it easy for inaccurate repositioning to affect tapping accuracy. In contrast, in this embodiment, the two tap assemblies 320 tap simultaneously, completing the machining of two tap positions in a single operation. This improves machining efficiency while ensuring the relative positional accuracy between the two tap positions, thereby enhancing the quality of the lock.

[0034] After the two tap assemblies 320 complete the tapping operation, the lifting structure 200 drives the tapping structure 300 upward, causing the tap assembly 320 to disengage from the lock and return to its initial position. Simultaneously, the clamping and fixing structure 500 releases its clamping end, releasing the clamping structure 600 from its fixation. The rotary motor assembly 410 in the turntable feeding structure 400 restarts, driving the clamping turntable 420 to continue rotating, moving the tapped lock away from its current position, and simultaneously conveying the next clamping structure 600 containing an untasted lock to the clamping end position of the clamping and fixing structure 500. Then, the above feeding and positioning, simultaneous tapping, and resetting steps are repeated to achieve continuous cyclic operation of the lock tapping process.

[0035] The aforementioned rotary lock tapping machine 10 uses two tap assemblies 320 to tap simultaneously, completing the processing of two thread positions in one operation. This reduces processing time, thereby increasing the processing quantity per unit time and improving overall production efficiency. It also avoids the problem of inaccurate positioning caused by the need for repositioning when tapping a single thread, thus ensuring the relative positional accuracy between the two thread positions and improving the processing quality of locks by the rotary lock tapping machine 10.

[0036] like Figures 1 to 2 As shown, in one embodiment, each tap assembly 320 includes a tap 321 and a tool holder 322. The tap 321 is fixed to the tool holder 322, which is connected to the split connector 310. The two taps 321 have the same thread outer diameter; or the two taps 321 have different thread outer diameters. In this embodiment, when the two taps 321 have the same thread outer diameter, it can be used to simultaneously process threads of the same specification on the lock. Two taps 321 with the same thread outer diameter can simultaneously tap threads of the same specification, ensuring that the processing parameters of each thread are consistent, resulting in a high degree of consistency in the threaded holes on the processed lock, thereby ensuring the assembly accuracy and stability between the various components of the lock.

[0037] Furthermore, when the outer diameters of the two taps 321 are different, the machining requirements for different specifications of thread positions on the lock can be met, thus enabling the machining of threaded holes of different specifications on the lock. Two taps 321 with different outer diameters can complete the machining of different specifications of thread positions in one operation, eliminating the need to change tools or perform multiple positioning and adjustments of the lock during machining. This improves machining efficiency, reduces errors caused by multiple clamping and positioning, and ensures the relative positional accuracy between different specifications of thread positions. By designing a structure where the outer diameters of the two taps 321 can be the same or different, the rotary lock tapping machine 10 can adapt to the machining needs of more types of locks, thereby improving the versatility and flexibility of the rotary lock tapping machine 10.

[0038] In another embodiment, the tool holder is connected to the shaft of the split connector to drive the tool holder to perform a tapping operation. Specifically, the split connector 310 has a drive mechanism inside, which is connected to the shaft and provides precise rotational power to the shaft. When the tapping structure 300 moves downward under the drive of the lifting structure 200 to contact the lock, the drive mechanism inside the split connector 310 is activated, driving the shaft to start rotating. Since the tool holder 322 is tightly connected to the shaft, the rotation of the shaft directly drives the tool holder 322 to rotate synchronously. The tap 321 is fixed to the tool holder 322, so the tap 321 also rotates with the rotation of the tool holder 322, thereby realizing the tapping operation on the lock.

[0039] like Figures 3 to 4As shown, in one embodiment, the clamping and fixing structure 500 includes a fixed base 510, a lifting stroke cylinder 520, a lifting connecting assembly 530, and a clamping member 540. The fixed base 510 is disposed on the frame 100, the lifting stroke cylinder 520 is fixed to the side of the fixed base 510, the lifting connecting assembly 530 is connected to the power output end of the lifting stroke cylinder 520, one end of the clamping member 540 is connected to the lifting connecting assembly 530, and the other end of the clamping member 540 is used to clamp the clamping structure 600. In this embodiment, the fixed base 510 provides a stable foundation support for the entire clamping and fixing structure 500, ensuring that it will not shake or shift due to external forces during operation, thereby ensuring the accuracy of the clamping position. When the clamping rotating disk 420 transports the clamping structure 600 equipped with the lock to the designated position, the stability of the fixed base 510 enables the clamping member 540 to accurately align with the clamping structure 600. The lifting stroke cylinder 520 controls the up-and-down movement of the lifting connecting assembly 530, thereby driving the clamping member 540 to achieve lifting action. When clamping the fixture structure 600 is required, the lifting stroke cylinder 520 drives the clamping member 540 to descend, making it tightly abut against the fixture structure 600 to provide sufficient clamping force, ensuring that the lock remains stable during tapping and will not be displaced or vibrated due to the rotation and feed of the tap assembly 320, thereby improving the accuracy and quality of tapping.

[0040] like Figures 3 to 4 As shown, in one embodiment, the lifting connection assembly 530 includes a lifting plate 531, a limiting member 532, and a transmission member 533. The limiting member 532 is fixed to the fixed base 510 and located above the lifting stroke cylinder 520. The limiting member 532 has a limiting groove 5301. One end of the transmission member 533 is connected to the power output end of the lifting stroke cylinder 520, and the other end of the transmission member 533 is connected to the lifting plate 531, so that the transmission member 533 drives the lifting plate 531 to slide within the limiting groove 5301. In this embodiment, the limiting groove 5301 provides precise track restriction for the lifting movement of the lifting plate 531. When the lifting stroke cylinder 520 drives the transmission component 533 to move the lifting plate 531, the lifting plate 531 can only move up and down along the path specified by the limit through groove 5301. This effectively avoids instability such as deviation or shaking of the lifting plate 531 during movement, ensuring that the clamping component 540 can accurately lift and lower according to the predetermined trajectory, thereby achieving precise clamping and releasing of the clamping structure 600, and thus improving the accuracy of lock clamping.

[0041] like Figures 3 to 4As shown, in one embodiment, the lifting connection assembly 530 further includes a transmission fixing bolt 534. The transmission component 533 has a first fixing through hole 5302, and the lifting plate 531 has a snap-fit ​​groove 5303 and a second fixing through hole 5304. The transmission component 533 is provided with a snap-fit ​​boss 5331. The transmission fixing bolt 534 passes through the first fixing through hole 5302 and the second fixing through hole 5304 in sequence, and the snap-fit ​​boss 5331 snaps into the snap-fit ​​groove 5303. In this embodiment, the transmission fixing bolt 534 passes through the first fixing through hole 5302 and the second fixing through hole 5304 in sequence, ensuring that the transmission component 533 and the lifting plate 531 can accurately transmit power. When the lifting stroke cylinder 520 drives the transmission component 533 to move, kinetic energy is transferred to the lifting plate 531, enabling the lifting plate 531 to move up and down according to a predetermined speed and stroke. This ensures the accuracy and stability of the clamping component 540's movement, thereby achieving reliable clamping and releasing of the clamping structure 600 and providing a stable foundation for the lock tapping process. Furthermore, due to the cooperation between the engaging boss 5331 and the engaging groove 5303, the transmission component 533 can only drive the lifting plate 531 to move along specific directions and positions, effectively preventing deviation during transmission and ensuring the accuracy and stability of the entire lifting connection assembly 530.

[0042] like Figure 6 As shown, in one embodiment, the clamping and fixing structure 500 further includes a support base 550, which is fixed to the frame 100 and disposed between the fixed base 510 and the turntable feeding structure 400. In this embodiment, when the lifting stroke cylinder 520 drives the clamping member 540 to perform lifting and lowering actions to clamp and release the clamping structure 600, a certain reaction force is generated. The support base 550 can effectively distribute and transmit the reaction force to the frame 100, preventing the fixed base 510 from deforming or shaking due to uneven force, thereby ensuring that the clamping and fixing structure 500 maintains a stable working state.

[0043] like Figures 1 to 2As shown, in one embodiment, the rotating motor assembly 410 includes a rotating component 411 and a drive motor 412. The fixture rotating disk 420 has a turntable through hole 4201. The rotating component 411 is connected to the power output end of the drive motor 412, and passes through the turntable through hole 4201 and is engaged with the inner wall of the turntable through hole 4201. In this embodiment, after the drive motor 412 starts, the rotational power it generates can be accurately and efficiently transmitted to the rotating component 411. The rotating component 411 passing through the turntable through hole 4201 and being engaged with the inner wall ensures a stable connection between the rotating component 411 and the fixture rotating disk 420. When the drive motor 412 drives the rotating component 411 to rotate, the fixture rotating disk 420 can rotate synchronously and stably, avoiding slippage or asynchrony, and ensuring that the fixture rotating disk 420 rotates accurately according to the set direction and speed.

[0044] like Figure 2 and Figure 5 As shown, in one embodiment, the fixture rotating disk 420 also has a first fixture fixing hole 4202. The fixture structure 600 includes a workpiece fixing platform 610, fasteners 620, and a fixture base plate 630. The workpiece fixing platform 610 is disposed on the fixture base plate 630, and the fixture base plate 630 has a second fixture fixing hole 6301. The fasteners 620 are sequentially inserted into the second fixture fixing hole 6301 and the first fixture fixing hole 4202. In this embodiment, when the fasteners 620 are sequentially inserted into the first fixture fixing hole 4202 and the second fixture fixing hole 6301, the fixture base plate 630 can be firmly fixed on the fixture rotating disk 420, ensuring that the fixture structure 600 will not shake or shift during rotation. This allows the locking device to remain in an accurate position during tapping, thereby ensuring the accuracy and quality of tapping.

[0045] like Figure 5As shown, in one embodiment, the workpiece fixing table 610 has a workpiece limiting groove 6101 and two tapping grooves 6102. The two tapping grooves 6102 are symmetrically arranged along the centerline of the workpiece fixing table 610, and the workpiece limiting groove 6101 is connected to the two tapping grooves 6102 respectively. In this embodiment, when the lock workpiece is placed on the workpiece fixing table 610, the workpiece limiting groove 6101 can restrict the movement of the lock workpiece on the workpiece fixing table 610, ensuring that the lock workpiece can only be placed in a specific position and direction. This allows the tap assembly 320 to accurately find the position to be tapped, avoiding tapping deviation caused by inaccurate placement of the lock workpiece, thereby improving the tapping precision and accuracy. In addition, the two tapping grooves 6102 are symmetrically arranged along the centerline of the workpiece fixing table 610 and are connected to the workpiece limiting groove 6101 respectively, providing a tapping channel for the tap assembly 320. During the tapping process, the tap assembly 320 directly contacts the part of the lock workpiece to be tapped through the tapping groove 6102, avoiding the tapping operation being affected by the obstruction of the workpiece fixing table 610.

[0046] like Figure 5 As shown, in one embodiment, the workpiece fixing table 610 has a limiting boss 611, which is disposed within the workpiece limiting groove 6101 and is used to fix the workpiece. In this embodiment, the setting of the limiting boss 611 further refines the precise placement of the lock workpiece within the workpiece limiting groove 6101. When the lock workpiece is placed into the workpiece limiting groove 6101, the limiting boss 611 can precisely engage with a specific part on the lock workpiece, providing precise positioning of the lock workpiece in the horizontal direction. This ensures that the part to be tapped is exactly within the tapping range of the two tap assemblies 320, avoiding tapping position deviation caused by the workpiece being placed too deep or too shallow.

[0047] Compared with the prior art, this disclosure has at least the following advantages:

[0048] The aforementioned rotary lock tapping machine 10 uses two tap assemblies 320 to tap simultaneously, completing the processing of two thread positions in one operation. This reduces processing time, thereby increasing the processing quantity per unit time and improving overall production efficiency. It also avoids the problem of inaccurate positioning caused by the need for repositioning when tapping a single thread, thus ensuring the relative positional accuracy between the two thread positions and improving the processing quality of locks by the rotary lock tapping machine 10.

[0049] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
