Description

Technical Field

[0001] The utility model relates to the technical field of lock body production equipment, in particular to a lean production line suitable for producing different lock bodies. Background Art

[0002] The lock body is the main component of the lock. There are many types of locks, such as one-way lock bodies, three-way lock bodies, four-way lock bodies, etc. They are widely used in anti-theft doors and play a basic protective role.

[0003] The main components of the lock body include the main body, lock tongue, large torsion spring, small torsion spring, inclined tongue, block, cover plate, square core and square core cap. The front side of the main body has an installation panel for installing the inclined tongue and lock tongue. The lock body as mentioned above is a necessary equipment for opening and closing doors and windows, and is crucial to the protection effect.

[0004] In the current lock body manufacturing technology, taking the Chinese utility model patent CN210878502U as an example, it discloses an innovative lock housing assembly system. The system integrates precision components such as housing feeding mechanism, feeding manipulator, lever feeding mechanism, lever feeding manipulator, lever spring feeding mechanism and corresponding spring feeding manipulator, realizing the automatic feeding and precise assembly of housing, lever and spring. This solution significantly enhances the automatic production capacity of lock housing, effectively reduces the dependence on manpower, and simultaneously improves production efficiency and saves costs.

[0005] Although this type of manufacturing solution has many advantages, it also exposes the following limitations:

[0006] Each feeding module in the current design, such as the dedicated feeding mechanism for the housing, lever and spring, is customized for a specific lock body model. When the production line needs to be switched to the production of a different type of lock body, the entire set of feeding equipment must be replaced as a whole. This "one-to-one" configuration mode is obviously contrary to the flexibility, versatility and rapid response to market demand advocated in the lean production concept, increasing equipment investment costs and production switching time, and is not conducive to the efficient operation of multi-variety, small-batch lock body production.

[0007] In view of this, the inventor specially designed a lean production line suitable for the production of different lock bodies, and this case was thus generated. Utility Model Content

[0065] At least one manual loading position 50 is provided on one side of the rotary channel 21;

[0066] And at least one of the following:

[0067] The lock tongue feeding mechanism 30 is arranged on the rotation path of the rotation channel 21 and is used to install the lock tongue on the lock body tooling 12 to the corresponding position in the lock body;

[0068] A small torsion spring feeding mechanism 40 is provided on the rotation path of the rotation channel 21 and is used to install the small torsion spring on the lock body tooling 12 to a corresponding position in the lock body;

[0070] The oblique tongue feeding mechanism 60 is arranged on the rotation path of the rotation channel 21 and is used to install the oblique tongue on the lock body tooling 12 to the corresponding position in the lock body;

[0071] The square core cap feeding mechanism 70 is arranged on the rotation path of the rotation channel 21 and is used to install the square core cap on the lock body tooling 12 to the corresponding position in the lock body;

[0072] The card block feeding mechanism 80 is arranged on the rotary path of the rotary channel 21 and is used to install the card block on the lock body tooling 12 to the corresponding position in the lock body;

[0073] The cover plate feeding mechanism 110 is arranged on the rotation path of the rotation channel 21 and is used to install the cover plate on the lock body tooling 12 to the upper end of the lock body to form a complete lock body;

[0074] The screw locking mechanism 120 is disposed on the rotation path of the rotation channel 21 and is located behind the cover plate feeding mechanism 110, and is used to lock the cover plate on the main body;

[0075] In this embodiment, the tooling conveying assembly 20 includes a transverse driving device 22 and a longitudinal driving device 23 .

[0076] Two transverse drive devices 22 are provided and are arranged at the bottom of the rotary channel 21 where the two long sides of the tooling conveying assembly 20 are located, and are used to drive the lock body tooling 12 to move horizontally to the corner position along the closed path formed by the rotary channel 21;

[0077] Two longitudinal drive devices 23 are provided and are arranged at the top of the rotary channel 21 where the two wide sides of the tooling conveying assembly 20 are located, and are used to drive the lock body tooling 12 located at the corner to move to the next corner of the rotary channel 21.

[0078] The lock body fixtures 12 are continuously and closely laid on the rotary channel 21 and form at least one vacant position of the same size as the lock body fixture 12 .

[0079] Preferably, it also includes:

[0080] The spot grease spraying mechanism 90 is arranged on the rotation path of the rotation channel 21 and is used to spray grease at corresponding positions in the lock body;

[0081] The visual inspection system 100 is arranged on the rotation path of the rotation channel 21 and is used to detect whether each component on the lock body is installed in place;

[0082] The testing device is arranged on the rotation path of the rotation channel 21 , and includes a lock tongue extension and torque detection mechanism 130 and a tilt tongue extension and torque detection mechanism 140 .

[0083] Specifically, Figure 3 , 45, the lateral drive device 22 includes a pair of transmission shafts 221, a transmission member 222 connected to the two transmission shafts 221, and a driving motor 223 for driving the transmission shaft 221 to rotate. The transmission member 222 is a synchronous wheel, a synchronous belt or a double-speed chain. In this embodiment, the lateral drive device 22 includes a pair of parallel transmission shafts 221, a pair of transmission members 222 arranged parallel between the two transmission shafts 221, and a driving motor 223 for driving the transmission shaft 221 to rotate. The rotary channel 21 includes a rectangular parallel block edge 211 and a plurality of support columns 212 for supporting the block edge 211. The support column 212 is correspondingly arranged on the upper end surface of the machine table 10 for installation and fixation. The area between adjacent retaining edges 211 forms a rotating path adapted to the edge of the lock body tooling 12. The two transmission shafts 221 are respectively arranged at the two ends of one of the long sides of the rotating path, and the two transmission members 222 transmitted on the two transmission shafts 221 are arranged close to the bottom of the edges on both sides of the rotating path. Therefore, each lock body tooling 12 is continuously driven by the two transmission members 222 to move horizontally along the rotating path of the rotating channel 21, so that the lock body tooling 12 is processed and assembled at each processing position on its movement path in turn, and finally moves to the end of the long side of the rotating channel 21 for discharge.

[0084] In addition, the transmission member 222 can be replaced by a synchronous wheel, a synchronous belt or a double-speed chain. In this embodiment, two parallel synchronous belts are specifically selected to realize the transmission of the lock body tooling 12 on the transmission member 222.

[0085] Preferably, Figure 3 , 45, it also includes a lifting mechanism 24 arranged at the inlet end of the lateral driving device 22 and used to smoothly transition the lock body tooling 12 to the conveying member 222. In this embodiment, the lifting mechanism 24 includes a fixed seat 241, a lifting cylinder 242 arranged on the fixed seat 241, and a lifting plate 243 fixed to the end of the output shaft of the lifting cylinder 242. The size of the lifting plate 243 is smaller than the minimum spacing of the rotary channel 21. The rotary channel 21 also includes a channel bottom plate 213 arranged between the bottoms of the two baffles 211. The belt surface of the conveying member 222 is respectively arranged on the upper and lower sides of the channel bottom plate 213, and the channel bottom plate 213 is penetrated at the corner position of the rotary channel 21 with a space for making way for the lifting plate 243. The designed lifting mechanism 24 can temporarily lift the lock body tooling 12 at its upper end to make its end rise, thereby preventing the side wall of the lock body tooling 12 from interfering with the synchronous belt at the edge during the transmission process, so that it can normally transition to the belt surface of two parallel synchronous belts, making the transmission process of the lock body tooling 12 simpler and controllable; in addition, the setting of the channel bottom plate 213, on the one hand, provides stable support for the lock body tooling 12, so that it can move stably along the rotary channel 21, and on the other hand, it also provides support for the belt surface of the conveying member 222 on its upper end surface, thereby preventing the middle section from being deformed under the heavy pressure of the lock body tooling 12, thereby achieving stable driving of the lock body tooling 12.

[0086] The longitudinal driving device 23 includes a support frame 231 arranged on both sides of the wide side of the rotary channel 21, a guide rail 232 spanning between the two support frames 231, a driving seat 233 slidably arranged on the guide rail 232, a driving cylinder 234 arranged on the guide rail 232 and used to drive the driving seat 233 to move, a positioning cylinder 235 arranged on the driving seat 233 and with its output direction facing the lower rotary channel 21, and a positioning rod 236 connected to the output shaft of the positioning cylinder 235 and vertically slidably arranged on both sides of the driving seat 233. In-position detection members are provided on the guide rail 232 and on both sides of the moving direction of the driving seat 233. In this embodiment, the in-position detection member is a travel switch. The spacing between the two positioning rods 236 is less than the minimum side length of the lock body tooling 12. In this embodiment, four openings extending to The spacing between the two positioning rods 236 in the U-shaped slot on its side is consistent with the spacing between the two U-shaped slots on the same side, and the U-shaped slot can completely accommodate the positioning rods 236. Therefore, when the lock body fixture 12 moves to the bottom of the longitudinal drive device 23, the positioning cylinder 235 is extended to allow the two positioning rods 236 to be inserted into the two U-shaped slots at the corresponding positions below it. Then, the driving cylinder 234 is extended and retracted to drive the driving seat 233 to move along the longitudinal direction of the rotary channel 21, so that the lock body fixture 12 can achieve longitudinal movement in the rotary channel 21. The two U-shaped slots on the other side of the lock body fixture 12 are opposite to the two positioning rods 236 of the longitudinal drive device 23 at the other corner of the rotary channel 21, so that it can achieve longitudinal movement on the other side of the rotary channel 21, thereby smoothly realizing the rotary motion of the lock body fixture 12. In this embodiment, the positioning grooves 1202 (combined with the positioning grooves 1202) are symmetrically arranged on both sides of the lock body fixture 12. Figure 4 ), the distance between the two positioning rods 236 is the same as the distance between the two positioning grooves 1202 on the same side, thereby facilitating the insertion of the positioning rods 236 and driving the lock body tooling 12 to move longitudinally.

[0087] In addition, the longitudinal drive device 23 can be set above the rotating channel 21 according to site requirements. If the site permits, the transverse drive device 22 can also be set on the horizontal side of the rotating channel 21, and the lock body tooling 12 can be pushed horizontally by the cylinder, eliminating other components.

[0088] Preferably, Figure 6As shown, it also includes a feeding conveying mechanism arranged on one side of the rotary channel 21, and the feeding and conveying mechanism 150 includes a pair of feeding conveyor belts 151 with different extension lengths, a feeding motor 152 that drives the feeding conveyor belts 151 to circulate, and a feeding clamping device for clamping and moving the complete lock body from the rotary channel 21 to one of the feeding conveyor belts 151. Specifically, the feeding clamping device includes a frame 153 with a sliding rod on the top, a feeding seat 154 slidingly arranged along the sliding rod, a telescopic component 155 arranged on the feeding seat 154, and a clamping device arranged at the output end of the telescopic component 155.

In this embodiment, the transverse movement assembly 157 is realized by a motor-driven belt circulation transmission, and one side of the unloading seat 154 is fixed on the belt, thereby realizing the overall transverse movement of the unloading seat 154. According to different scenarios, the clamping claw assembly 156 on the unloading clamping device can also be replaced with a magnetic or air suction clamping device, which is not limited here.

In this embodiment, the torsion spring fixing kit 46 is respectively set to a sleeve type or a limit type according to the large torsion spring and the small torsion spring. Therefore, during the working process, the large torsion spring or the small torsion spring is first clamped from the lock body tooling 12 by the torsion spring clamping device 45, and it is moved to the torsion spring limiting seat 48 for compression deformation so that it is deformed into an installable state. Subsequently, the deformed large torsion spring or the small torsion spring is taken out by the torsion spring fixing kit 46, and it is placed in the corresponding installation position in the lock body main body in an installed state to complete the installation process of the large torsion spring and the small torsion spring.

The unloading and conveying mechanism 150 is connected to the rearmost position of the above mechanisms.

[0105] The working process and beneficial effects of the utility model are as follows:

[0106] First, a plurality of transmission substrates 1201 of lock body fixtures 12 are placed on the rotary channel 21 and laid closely together. When the equipment is started, the transmission members 222 of the two horizontal drive devices 22 drive the lock body fixtures 12 to synchronously move in opposite directions along the two long sides of the rotary channel 21. When the frontmost lock body fixture 12 reaches the end of the long side of the rotary channel 21, that is, the corner position of the rotary channel 21, the stop mechanism stops the lock body fixture 12 following it. The lock body fixture 12 at the corner position is then pushed by the longitudinal moving device to move toward the wide side of the rotary channel 21. During the movement, the lock body fixture 12 retained in front is also pushed synchronously. Thus, the lock body fixture 12 at the end of the wide side of the rotary channel 21 is 2 is synchronously pushed to the long side entrance end of the rotary channel 21, and temporarily stops under the action of the lifting mechanism 24. After the lock body tooling 12 in front continues to be transmitted backward, the lifting mechanism 24 descends, so that the lock body tooling 12 continues to move backward under the action of the lateral driving device 22. One side of the rotary channel 21 is set as the worker feeding side, and the operator places the main body, cover plate and various parts of the lock body on the corresponding positions on the lock body tooling 12 on this side. The opposite side of the rotary channel 21 is set as the assembly side, and various assembly mechanisms are set to assemble various parts into the lock body respectively, and automatically lock and automatically detect, and finally the qualified products and unqualified products are separately transmitted, so as to realize the convenient assembly of the lock body tooling 12.

[0107] The utility model realizes the continuous and orderly movement of the lock body tooling 12 in the rotary channel 21 by adopting a rectangular rotary tooling transmission component 20, in conjunction with a transverse drive device 22 and a longitudinal drive device 23. When the lock body model to be produced needs to be changed, it can be realized by simply replacing the corresponding lock body tooling 12, thereby adapting to lock bodies of different models and specifications, enhancing its versatility, reducing equipment downtime caused by changing product models, and improving production efficiency.

[0108] In addition, the equipment integrates a grease spraying mechanism 90, a visual inspection system 100 and a testing device, which can lubricate key parts of the lock body, monitor the installation status of components in real time, and test the telescopic and torsional performance of the lock tongue and the oblique tongue, ensuring stable and reliable product quality and meeting strict process requirements.

[0109] In summary, the production equipment adapted to different lock bodies provided by the utility model realizes flexible adaptation and efficient production of various lock body models through modular design, efficient automated processes, comprehensive quality control and fine structural design, and significantly improves the economic benefits and market responsiveness of lock body manufacturing.

[0110] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
