Description

Technical Field

[0001] The utility model relates to the technical field of lock body tooling and a transmission device, in particular to a lock body tooling and a transmission mechanism with positioning. 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] like Figure 1 As shown, the main components of the lock body include a main body 10, a lock tongue 12, a large torsion spring 13, a small torsion spring 14, a slanted tongue 15, a block 16, a cover plate 11, a square core 17 and a square core cap 18, etc. The front side of the main body 10 has an installation panel 19 for installing the slanted tongue 15 and the lock tongue 12. The lock body as mentioned above is a necessary device for opening and closing doors and windows, and is crucial to the protective effect.

[0004] The current lock body manufacturing scheme, for example, China's announcement number CN210878502U discloses a lock housing assembly machine that uses a housing feeding mechanism, a feeding manipulator device, a lever feeding mechanism, a lever feeding manipulator, a lever spring feeding mechanism, and a lever spring feeding manipulator to achieve automatic feeding and automatic assembly of the housing, lever, and lever spring. This method effectively improves the degree of automated production and assembly of the lock housing, reduces dependence on manual labor, and at the same time improves production efficiency and reduces production costs.

[0005] However, this lock body manufacturing solution still has some shortcomings:

[0006] 1. All components of the lock body feeding, such as the shell feeding mechanism, lever feeding mechanism, lever spring feeding mechanism, etc., are dedicated to a single lock body model and cannot meet the production needs of multiple models of lock bodies. If other models of lock bodies need to be produced, the entire set of feeding equipment needs to be replaced, which does not conform to the principles of lean production;

[0007] 2. The existing lock body tooling is not accurate enough in positioning the lock body and its internal components, which ultimately affects the production qualification rate of the lock body.

[0008] In view of this, the inventor specially designed a lock body tooling and a transmission mechanism with positioning, and this case was thus generated. Utility Model Content

[0009] In order to solve the above problems, one of the technical solutions of the utility model is as follows:

[0015] Preferably, the lock tongue fixing area and the inclined tongue fixing area are respectively arranged on both sides of the accommodating area, and the square core cap fixing area is arranged on one side of the lock body fixing area close to the inclined tongue fixing area. The large torsion spring fixing area, the small torsion spring fixing area, and the block fixing area are all arranged on the front side of the accommodating area.

[0016] Preferably, a hollow installation groove is arranged between the two fixing columns in the main body fixing area, a bearing part is arranged in the installation groove, and an insertion structure that can be inserted into the lock body square core is arranged in the middle of the bearing part.

[0017] Preferably, a front limiting groove for inserting and fitting with the bottom of the lock body installation panel is arranged on one side of the lock body fixing area close to the accommodating area so that the main body of the lock body can be stably placed on the end face of the tooling base plate.

[0018] Preferably, the tooling base plate is square, and several U-shaped slots with openings extending to its sides are arranged on both sides of it.

[0019] The second technical solution of the present utility model is as follows:

[0021] A rotary mechanism, which is rotatably arranged in a rectangular shape, and a closed rotary channel is formed at its upper end for the rotary movement of several continuously arranged lock body toolings;

[0022] Two transverse driving devices, which are used to drive the lock body tooling to horizontally move along the closed path formed by the rotary channel;

[0023] Two longitudinal drive devices are provided, which are used to drive the lock body tooling to move longitudinally along the closed path formed by the rotary channel;

[0024] Wherein, the lock body tooling is continuously and closely laid on the rotary channel and forms at least one vacant position of the size of the lock body tooling.

[0025] Preferably, the transverse drive device includes a pair of transmission shafts, a transmission member connected to the two transmission shafts, and a drive motor for driving the transmission shafts to rotate, and the transmission member is one of a synchronous wheel, a synchronous belt or a double-speed chain.

[0064] Embodiment 2

[0065] See also Figures 6 to 12 , is a transmission mechanism for transmitting lock body tooling as a second embodiment of the utility model, comprising:

[0066] The rotary mechanism 50 is arranged to rotate in a rectangular shape, and a closed rectangular rotary channel 51 is formed at its upper end for rotating a plurality of continuously arranged lock body fixtures 20. In this embodiment, the rotary mechanism 50 is integrally mounted and fixed on the upper end of the machine platform 100;

[0067] Two transverse driving devices 60 are provided and are respectively arranged at the bottom of the rotary channel 51 where the two long sides of the rotary mechanism 50 are located, and are used to drive the lock body tooling 20 to move horizontally to the corner position along the closed path formed by the rotary channel 51, that is, to drive the lock body tooling 20 to move from one end of the long side of the rotary channel 51 to the other end, and the movement directions of the two transverse driving devices 60 are opposite;

[0068] Two longitudinal drive devices 70 are provided and are respectively arranged at the top of the rotation channel 51 where the two wide sides of the rotation mechanism 50 are located, and are used to drive the lock body fixture 20 located at the corner to move to the next corner of the rotation channel 51, that is, drive the lock body fixture 20 to move along the end of one long side of the rotation channel 51 to the starting movement end of the other long side of the rotation channel 51, and the movement directions of the two longitudinal drive devices 70 are opposite, so as to cooperate with the two transverse drive devices 60 to form a rectangular rotation path for a plurality of lock body fixtures 20;

[0069] Among them, the lock body tooling 20 is continuously and densely laid on the rotating channel 51 and at least one vacant position the size of the lock body tooling 20 is formed. Therefore, at least one vacant position the size of the lock body tooling 20 can allow the lock body tooling 20 continuously and densely laid on the rotating channel 51 to smoothly realize the rotating motion and avoid interference at the corner position, so that the tooling can be recycled.

[0070] Preferably, Figure 8 , 910, the lateral drive device 60 includes a pair of transmission shafts 61, a transmission member 62 connected to the two transmission shafts 61, and a driving motor 63 for driving the transmission shaft 61 to rotate. The transmission member 62 is a synchronous wheel, a synchronous belt or a double-speed chain. In this embodiment, the lateral drive device 60 includes a pair of parallel transmission shafts 61, a pair of transmission members 62 arranged parallel between the two transmission shafts 61, and a driving motor 63 for driving the transmission shaft 61 to rotate. The rotary channel 51 includes a rectangular parallel block edge 511 and a plurality of support columns 512 for supporting the block edge 511. The support column 512 is a plurality of support columns 513. 12 is correspondingly arranged on the upper end surface of the machine table 100 for installation and fixation, the area between the adjacent retaining edges 511 forms a rotation path adapted to the edge of the lock body tooling 20, the two transmission shafts 61 are respectively arranged at the two ends of one of the long sides of the rotation path, and the two transmission members 62 transmitted on the two transmission shafts 61 are arranged close to the bottom of the edges on both sides of the rotation path, so that each lock body tooling 20 is continuously driven by the two transmission members 62 to move horizontally along the rotation path of the rotation channel 51, so that the lock body tooling 20 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 rotation channel 51 for discharge.

[0071] In addition, the transmission member 62 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 20 on the conveyor belt.

[0072] Preferably, Fig. 9 As shown, it also includes a lifting mechanism 80 disposed at the inlet end of the lateral driving device 60 and used to smoothly transition the lock body tooling 20 to the conveying member 62. In this embodiment, the lifting mechanism 80 includes a fixed seat 81, a lifting cylinder 82 disposed on the fixed seat 81, and a lifting plate 83 fixed to the end of the output shaft of the lifting cylinder 82. The size of the lifting plate is smaller than the minimum spacing of the rotary channel 51. The rotary channel 51 also includes a channel bottom plate 513 disposed between the bottoms of the two stop edges 511. The belt surface of the conveying member 62 is respectively disposed on the upper and lower sides of the channel bottom plate 513, and the channel bottom plate 513 is penetrated at the corner position of the rotary channel 51 to provide a clearance groove 514 for making way for the lifting plate. Therefore, the designed lifting mechanism 80 can temporarily lift the lock body tooling 20 at its upper end to make its end rise, thereby preventing the side wall of the lock body tooling 20 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 20 simpler and controllable; in addition, the setting of the channel bottom plate 513, on the one hand, provides stable support for the lock body tooling 20, so that it can move stably along the rotating channel 51, and on the other hand, it also provides support for the belt surface of the conveying member 62 on its upper end surface, avoiding deformation of the middle section under the heavy pressure of the lock body tooling 20, thereby achieving stable driving of the lock body tooling 20.

[0073] Preferably, Fig.11 As shown, the longitudinal drive device 70 includes a support frame 71 arranged on both sides of the wide side of the rotary channel 51, a guide rail 72 spanning between the two support frames 71, a driving seat 73 slidably arranged on the guide rail 72, a driving cylinder 74 arranged on the guide rail 72 and used to drive the driving seat 73 to move, a positioning cylinder 75 arranged on the driving seat 73 and with its output direction facing the lower rotary channel 51, and a positioning rod 76 connected to the output shaft of the positioning cylinder 75 and vertically slidably arranged on both sides of the driving seat 73. On the guide rail 72 and on both sides of the moving direction of the driving seat 73, there are in-position detection members 77. In this embodiment, the in-position detection member 77 is a travel switch. The spacing between the two positioning rods 76 is less than the minimum side length of the lock body fixture 20. In this embodiment, four U-shaped openings extending to the side edges of the lock body fixture 20 are symmetrically arranged on both sides of the lock body fixture 20. The spacing between the two positioning rods 76 is consistent with the spacing between the two U-shaped slots 22 on the same side, and the U-shaped slots 22 can completely accommodate the positioning rods 76. Therefore, when the lock body tooling 20 moves to the bottom of the longitudinal drive device 70, the positioning cylinder 75 is extended to allow the two positioning rods 76 to be inserted into the two U-shaped slots 22 at the corresponding positions below it, and then the driving cylinder 74 is extended and retracted to drive the driving seat 73 to move along the longitudinal direction of the rotary channel 51, so that the lock body tooling 20 can realize longitudinal movement in the rotary channel 51. The two U-shaped slots 22 on the other side of the lock body tooling 20 are opposite to the two positioning rods 76 of the longitudinal drive device 70 at the other corner of the rotary channel 51, so that it can realize longitudinal movement on the other side of the rotary channel 51, thereby smoothly realizing the rotary motion of the lock body tooling 20.

[0074] In addition, the longitudinal drive device 70 can be set above the rotating channel 51 according to site requirements. If the site permits, the transverse drive device 60 can also be set on the horizontal side of the rotating channel 51, and the lock body tooling 20 can be pushed horizontally by the cylinder, eliminating other components.

[0075] In addition, a stop mechanism 90 is provided on the front side of the longitudinal drive device 70, including a door frame 91 arranged above the rotating channel 51, a pair of stop cylinders 92 arranged on the door clamp with the output direction facing the lower rotating channel 51, and a stop bar 93 arranged at the end of the output shaft of the stop cylinder 92. The two stop bars 93 correspond to the two opposite U-shaped slots 22 on the front side of the movement direction of the aforementioned lock body tooling 20. When the stop cylinder 92 is extended, the stop bar 93 is inserted into the two U-shaped slots 22 at the corresponding positions, and at this time is located on the front side of the movement direction of the lock body tooling 20, thereby achieving the stopping of the lock body tooling 20, facilitating the movement control of the lock body tooling 20, and cooperating with the jacking mechanism 80 to further avoid the lock body tooling 20 from generating movement interference at the corner position of the rotating channel 51.

[0076] The working process and beneficial effects of the utility model are as follows:

[0077] First, the tooling base plates 21 of a plurality of lock body toolings 20 are placed on the rotary channel 51 and laid closely and continuously. When the equipment is started, the conveying members 62 of the two transverse drive devices 60 drive the lock body toolings 20 to move synchronously in opposite directions along the two long sides of the rotary channel 51. When the frontmost lock body tooling 20 reaches the end of the long side of the rotary channel 51, that is, the corner position of the rotary channel 51, the stop mechanism 90 stops the lock body tooling 20 that follows it, and the lock body tooling 20 at the corner position is immediately stopped. The lock body tooling 20 located at the end of the wide side of the rotary channel 51 is synchronously pushed to the entrance end of the long side of the rotary channel 51 and temporarily stops under the action of the lifting mechanism 80. After the lock body tooling 20 in front continues to be transmitted backward, the lifting mechanism 80 descends, so that the lock body tooling 20 continues to move backward under the action of the transverse driving device 60.

[0078] During this process, one of the two long sides of the rotary channel 51 can be used as the loading side of the lock body tooling 20, and a number of operators put corresponding parts into the cover plate fixing area 32, the main body fixing area 31, the lock tongue fixing area 41, the large torsion spring fixing area 42, the small torsion spring fixing area 43, the inclined tongue fixing area 44, the block fixing area 46 and the square core cap fixing area 45 on the blank lock body tooling 20, and the other long side can be used as the processing side, and the lock tongue, large torsion spring, small torsion spring, inclined tongue, block, cover plate 11, square core and square core cap are assembled to the main body 10 and tested by automated assembly equipment, and qualified products are clamped out by corresponding clamping equipment from the transmission end of the processing side, and the addition of corresponding testing equipment can also identify defective products, thereby separately removing the defective products.

[0079] Beneficial effects:

[0080] 1. By providing an adjustable lock body fixing area 30 and a parts fixing area 40, the lock body fixture 20 can adapt to lock bodies of different models and specifications, thereby enhancing its versatility, reducing equipment downtime caused by changing product models, and improving production efficiency.

[0081] 2. The positioning column and the specially designed part fixing area 40 provide precise positioning for the lock body and its parts, ensuring the accuracy of the assembly process, thereby improving the assembly quality and production qualification rate of the lock body.

[0082] 3. With the help of the transverse drive device 60 and the longitudinal drive device 70 in the rotary mechanism 50, the automatic transmission and positioning of the lock body tooling 20 are realized. With a certain amount of manual workstations, the efficiency of lock body assembly can be further improved. When other types of lock bodies need to be assembled, it is only necessary to replace the corresponding lock body tooling 20 without replacing the entire equipment used for loading.

[0083] 4. The designed lifting mechanism 80 can temporarily lift the lock body tooling 20 at its upper end so that its end rises, so that it can be normally transferred to the conveying member 62, thereby making the transmission process of the lock body tooling 20 simpler and more controllable.

[0084] 5. The continuous rotary transmission design and positioning structure optimize the entire production process, reduce the space occupied on the production line, and realize the efficient recycling of the lock body tooling 20.

[0085] 6. Through the reasonable design of the drive system of the transmission mechanism, rapid conversion between order change and production expansion can be achieved to meet different production needs and provide good expansion potential.

[0086] In summary, the design of the lock body tooling 20 and the conveying mechanism of the utility model greatly improves the accuracy and efficiency of lock body assembly, effectively reduces production costs, and at the same time has better product adaptability and can quickly convert tooling to adapt to the production of lock bodies of various models and specifications.

[0087] 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.
