Description

Technical Field

[0001] The invention relates to the technical field of lock processing, in particular to a lock body and lock tongue assembly machine and an assembly method thereof. Background Art

[0002] The deadbolt is one of the components of the lock and the central part of the door lock. Its shape and functional design are mainly to fix the position between the door leaf and the door frame, thereby achieving the closing and locking of the door.

[0003] A bolt assembly machine disclosed in announcement number CN210025207U relates to the technical field of lock production devices. The bolt assembly machine includes an operating table, the top of which is fixed with a bolt assembly machine body by bolts, and the bottom of the operating table is welded with support tubes near the four corners. For operators of different heights, the bolt assembly machine can turn the hand plate by hand, and the hand plate drives the first threaded rod to rotate in the threaded tube. The operating table will drive the support tube and the slide rod to move, and the height of the entire device can be adjusted to meet the needs of the operator. Before use, you can check whether the pointers set around the operating table are aligned with the calibration block. If there is a misalignment, you can twist the corresponding second threaded rod, and the second threaded rod rotates in the threaded base to adjust the height of that side. When the four pointers all point to the calibration block, it means that the operating table is no longer tilted at this time, ensuring that the production will not be affected by the tilt of the operating table.

[0004] In the prior art, the height of the support tube is adjusted to accommodate workers of different heights in assembling the lock tongue. However, in actual operation, it is found that although this device solves the height problem, during the assembly process, the workers still need to clamp and fix the lock body and lock tongue to facilitate subsequent assembly. However, this causes the workers to feel tired after working for a long time. When assembling in a tired state, errors may occur in the installation of the lock, thereby affecting the quality of the lock body assembly, increasing the scrap rate of the product, and possibly requiring rework, thereby increasing production costs.

[0051] The material conveying assembly 8 is arranged between the material storage assembly 9 and the driving assembly 5 and is used for conveying the lock body;

[0052] The assembly component 2 includes an assembly table 21; the fixing component 3 is arranged on the assembly table 21; the fixing component 3 includes a fixing base 31; the fixing base 31 is fixedly connected to the assembly table 21; the fixing base 31 is provided with four groups; the bottom of the fixing base 31 is rotatably connected to a driving shaft 32; the end of the driving shaft 32 away from the fixing base 31 is fixedly connected to a crown gear 33; the side wall of the fixing base 31 is fixedly connected to a middle plate 36; the side wall of the middle plate 36 is rotatably connected to a bidirectional screw rod 34; the end of the bidirectional screw rod 34 away from the middle plate 36 is rotatably connected to the side wall of the fixing base 31; the bidirectional screw rod 34 is fixedly connected to a transmission gear 35; the transmission gear 35 is meshed with the crown gear 33; the bidirectional screw rod 34 is threadedly connected to a connecting plate 37; the side wall of the fixing base 31 is fixedly connected to a rubber plate 38; the connecting plate 37 is arranged to penetrate the rubber plate 38; the end of the connecting plate 37 away from the bidirectional screw rod 34 is fixedly connected to a fixing plate 371;

[0053] During operation, in the prior art, the height of the support tube is adjusted to accommodate workers of different heights to perform the assembly of the lock tongue. However, in the actual operation process, it is found that although this device solves the height problem, during the assembly process, the workers still need to clamp and fix the lock body and lock tongue to facilitate subsequent assembly. However, this causes the workers to feel tired after working for a long time. When assembling in a tired state, errors may occur in the installation of the lock, thereby affecting the quality of the lock body assembly, increasing the scrap rate of the product, and possibly requiring rework, thereby increasing the production cost. In order to prevent such incidents from happening, first, a large number of lock bodies are placed in the storage component 9, and then the lock bodies in the storage component 9 are transported to the feeding component 8, and then the loading component 6 on the driving component 5 is used to load the lock bodies into the fixing component 3, and after the meshing component 4 drives the fixing component 3 to fix the lock bodies, the assembly component 4 is assembled. Part 2 moves the fixing assembly 3 and the lock body to the bottom of the riveting mechanism 7, assembles the lock body and the lock tongue, and finally carries out unloading. Through the arrangement of the feeding assembly 6 and other components such as the fixing assembly 3, automatic loading of the lock body can be realized, and the automatic fixing and clamping of the lock body can be realized after automatic loading, reducing the steps of manual clamping, improving work efficiency, and reducing the defective rate of the product. After the feeding assembly 6 clamps the lock body to the rubber plate 38 in the fixed base 31, the driving shaft 32 and the crown gear 33 at the bottom of the fixed base 31 are driven to rotate. When rotating, the crown gear 33 drives the two sets of transmission gears 35 above to rotate, and then drives the two sets of bidirectional screw rods 34 to rotate. When the bidirectional screw rod 34 rotates, it will drive the two sets of fixing plates 371 to move toward the lock body, and then use the fixing plates 371 to clamp and fix the lock body. After the fixing is completed, the assembly table 21 is driven to move the fixed base 31 to the bottom of the riveting mechanism 7 for assembling the lock tongue.

[0054] like Figure 2-Figure 9As shown, the meshing assembly 4 includes a meshing base 41 and a limiting sleeve 44; the meshing base 41 and the limiting sleeve 44 are fixedly connected below the fixed base 31; a hexagonal column 42 is slidably connected in the limiting sleeve 44; a meshing gear 43 is fixedly connected to the middle of the hexagonal column 42; the driving assembly 5 includes a driving base 51; the driving base 51 is fixedly connected to the workbench 1; a driving groove 52 is opened in the middle of the driving base 51; the feeding assembly 6 includes a moving block 61; the moving block 61 is slidably connected in the driving groove 52; the end of the moving block 61 away from the driving groove 52 is fixedly connected to the connecting block 62; the side wall of the connecting block 62 is fixedly connected to the connecting tooth 621; the end of the connecting block 62 away from the moving block 61 is rotatably connected to the rotating column 63; the rotating gear 64 is fixedly connected to the rotating column 63; the end of the rotating column 63 away from the connecting block 62 is fixedly connected to the telescopic cylinder 65; the telescopic cylinder 65 away from the rotating column 63 A clamping arm 66 is hinged at one end; the first driving rod 53 and the second driving rod 55 are rotatably connected at both ends of the driving base 51; the first driving rod 53 is fixedly connected with the first driving gear 531 and the first driven gear 532; the second driving rod 55 is fixedly connected with the second driving gear 551 and the second driven gear 552; the first driving gear 531 and the second driving gear 551 are sleeved with the first driving belt 54; the connecting teeth 621 are meshed and connected with the first driving belt 54; the first driven gear 532 is movably meshed with the meshing gear 43; a top plate 10 is fixedly connected to the workbench 1; the top plate 10 is fixedly connected to the end of the driving base 51 away from the second driving rod 55; a telescopic spring 101 is fixedly connected inside the top plate 10; the end of the telescopic spring 101 away from the top plate 10 is fixedly connected to the top column 102; the top column 102 is protruding from the top plate 10; the end of the top column 102 is movably abutted against the hexagonal column 42;

[0055] During operation, the moving block 61 in the driving groove 52 is connected via a linear motor so that it can move linearly in the driving groove 52. The clamping arm 66 is used to clamp the lock body from the feeding assembly 8. After clamping, the moving block 61 is driven to move toward the assembly table 21. While moving, the assembly table 21 is driven to rotate, and the fixed base 31 is rotated to be parallel to the driving base 51. When the fixed base 31 is about to reach the parallel position of the driving base 51, the bottom engaging base 41 contacts the top column 102 on the lower top plate 10 and squeezes the top column 102 into the top plate 10. At the same time, the telescopic spring 101 inside the top plate 10 is squeezed. When the fixed base 31 completely reaches the parallel position of the driving base 51, the top column 102 is engaged with the bottom of the base 41. The notch contacts the hexagonal column 42, and then the telescopic spring 101 rebounds to lift the top column 102, and at the same time, the hexagonal column 42 is pushed into the fixed base 31 to engage with the drive shaft 32, and when the hexagonal column 42 is lifted, the meshing gear 43 on the hexagonal column 42 is lifted to a certain height, just so that the meshing gear 43 is meshed and connected with the first driven gear 532 on the drive base 51. At this time, the clamping arm 66 also reaches the top of the fixed base 31, and then the telescopic cylinder 65 drives the clamping arm 66 to descend, placing the lock body in the fixed base 31. After placement, the moving block 61 is driven to move away from the fixed base 31 to the feeding assembly 8. When the moving block 61 is away from the fixed base 31, the connecting teeth 621 above the moving block 61 will drive the first driving belt 54 to move When the first driving belt 54 moves, it will drive the first driving gear 531 and the second driving gear 551 to rotate, and the first driving gear 531 will drive the first driven gear 532 on the first driving rod 53 to rotate, and then the first driven gear 532 will drive the meshing gear 43 to rotate. When the meshing gear 43 rotates, it will drive the hexagonal column 42 to rotate, and the hexagonal column 42 will drive the driving shaft 32 and the crown gear 33 to rotate, and then drive the fixing plate 371 to clamp and fix the lock body. When the moving block 61 reaches the feeding assembly 8, the lock body is fixed, and then the assembly table 21 is driven to rotate, and the fixed base 31 with the lock body is moved to the bottom of the riveting mechanism 7 to assemble the lock tongue. While the assembly table 21 is rotating, the next group of The fixed base 31 reaches the parallel position of the driving base 51 again and contacts the top column 102. At the same time, the moving block 61 drives the clamping arm 66 and the lock body on the clamping arm 66 to reach the fixed base 31 again. Then the clamping arm 66 places the lock body on the fixed base 31 again. The above steps are repeated to fix the next group of lock bodies. Through the arrangement of the fixed base 31 and the meshing base 41, the first transmission gear 35 and the meshing gear 43 can be used to fix the lock body while feeding the material, thereby reducing the operating cost of the equipment and increasing the clamping speed of the lock body, thereby improving the assembly efficiency of the lock body and the lock tongue. Through the arrangement of the top plate 10 and the top column 102, the meshing gear 43 can be lifted up when the fixed base 31 moves to the parallel position of the driving base 51.It is meshed with the first driven gear 532 to avoid the phenomenon of jamming caused by direct meshing between the two.

[0056] like Figure 7 As shown, the side wall of the driving base 51 is fixedly connected with a side rack 56; the side rack 56 is meshedly connected with the rotating gear 64;

[0057] During operation, when the clamping arm 66 clamps the lock body from the feeding assembly 8, the clamping arm 66 faces the feeding assembly 8. When the moving block 61 moves the clamping arm 66, the rotating gear 64 on the rotating column 63 is driven by the side gear to drive the clamping arm 66 to rotate 180 degrees, so that the clamping arm 66 faces the fixed base 31 when reaching above the fixed base 31, which facilitates the placement of the lock body.

[0058] like Figure 7-Figure 9 As shown, the feeding assembly 8 includes a first support column 81; the first support column 81 is fixedly connected to the workbench 1; the end of the first support column 81 away from the workbench 1 is rotatably connected to the first connecting column 85; the end of the first connecting column 85 away from the first support column 81 is fixedly connected to the feeding platform 83; the feeding platform 83 is provided with a loading slot 84; the first connecting column 85 is fixedly connected to the feeding gear 82; the storage assembly 9 includes a second support column 91; the second support column 91 is fixedly connected to the workbench 1; the second support column 91 is away from the workbench One end of the workbench 1 is rotatably connected to a second connecting column 96; a material storage gear 92 is fixedly connected to the second connecting column 96; an end of the second connecting column 96 away from the second supporting column 91 is fixedly connected to a material storage bin 95; a rotating column 93 is rotatably connected inside the material storage bin 95; a stirring rod 94 is fixedly connected to the side wall of the rotating column 93; the output end of the second connecting column 96 is fixedly connected to the input end of the rotating column 93; a second driving belt 553 is sleeved on the material storage gear 92 and the second driven gear 552; the feed gear 82 is meshedly connected to the second driving belt 553;

[0059] During operation, when the clamping arm 66 is away from the feeding platform 83, the loading slot 84 on the feeding platform 83 is located below the storage bin 95. When the clamping arm 66 moves toward the feeding platform 83, it drives the first driving belt 54 to move through the connecting teeth 621, and then uses the first driving belt 54 to drive the second driven gear 552 on the second driving rod 55 to rotate. When the second driven gear 552 rotates, the second driving belt 553 is used to drive the storage gear 92 and the feeding gear 82 to rotate. When the storage gear 92 rotates, it drives the rotating column 93 and the stirring rod 94 in the storage bin 95 to rotate. When the stirring rod 94 rotates, it pushes the lock body At the connection between the storage bin 95 and the feed platform 83, there is a notch. When the lock body reaches the notch, it will fall into the loading slot 84 on the feed platform 83. At the same time, when the feed gear 82 is rotated by the second driving belt 553, it will drive the feed platform 83 to rotate, and rotate the loading slot 84 loaded with the lock body to the bottom of the clamping arm 66 at the driving base 51. At this time, the telescopic cylinder 65 drives the clamping arm 66 to descend to clamp the lock body and then move it to the fixed base 31. While moving, the second driving belt 553 is used to drive the storage gear 92 and the feed gear 82 to rotate, so that the loading slot 84 moves to the bottom of the storage bin 95 to receive the material.

[0061] During operation, the fixed base 31 assembled by the riveting mechanism 7 rotates again and rotates it to the discharge box 22. During rotation, the meshing gear 43 in the bottom meshing base 41 will drop a certain distance due to the loss of the lifting of the top column 102, but when it drops a certain distance, the hexagonal column 42 is still engaged with the driving shaft 32 in the fixed base 31, and the dropped distance is just parallel to the discharge teeth 26 under the assembly table 21. During rotation, the meshing gear 43 will mesh with the discharge teeth 26, and the drive of the discharge teeth 26 will drive the hexagonal column 42 to reverse again, so that the fixed plate 371 is away from the lock body, and then the discharge screw 25 drives the slider 23 and the ejector 24 to move, and the ejector 24 passes through the discharge groove 39 to eject the lock body out of the fixed base 31.

[0062] like Figure 1 As shown, a material discharge channel 11 is fixedly connected to the side wall of the workbench 1; the material discharge channel 11 is arranged below the assembly table 21;

[0063] During operation, the lock body ejected by the ejector pin 24 will fall into the material discharge channel 11 and be discharged through the material discharge channel 11 .

[0064] See also Figure 1-Figure 11 As shown, the present application provides a lock body and lock tongue assembly method, comprising the following steps:

[0065] S1, the lock bodies are uniformly placed in the storage bin 95, and then the stirring rod 94 in the storage bin 95 is driven to rotate, so that the lock bodies fall from the bin opening of the storage bin 95 to the loading slot 84 on the feeding platform 83;

[0066] S2, control the clamping arm 66 to clamp the lock body in the loading slot 84 onto the fixed base 31, then the moving block 61 drives the clamping arm 66 back to the feeding platform 83, and while moving back, the first driven gear 532 and the meshing gear 43 are used to drive the fixing plate 371 to clamp and fix the lock body;

[0067] S3, then drive the assembly platform 21 to rotate, move the lock body to the bottom of the riveting mechanism 7, assemble the lock tongue to the lock body, and then move the assembly platform 21 to the material box 22 again. When moving, the meshing gear 43 contacts and rotates with the material teeth 26, so that the fixing plate 371 releases the lock body, and then the lock body is pushed to the material channel 11 by the ejector pin 24 for material removal;

[0068] During operation, the lock bodies are uniformly placed in the storage bin 95, and then the stirring rod 94 in the storage bin 95 is driven to rotate, so that the lock bodies fall from the port of the storage bin 95 into the loading slot 84 on the feeding platform 83, and the clamping arm 66 is controlled to clamp the lock bodies in the loading slot 84 onto the fixed base 31, and then the moving block 61 drives the clamping arm 66 back to the feeding platform 83, and while moving back, the first driven gear 532 and the meshing gear 43 are used to drive the fixing plate 371 to clamp and fix the lock bodies, and then the assembly platform 21 is driven to rotate and the lock bodies are moved to the bottom of the riveting mechanism 7. After the lock tongue is assembled onto the lock body, the assembly platform 21 is moved to the unloading box 22 again, and during the movement, the meshing gear 43 contacts and rotates with the unloading teeth 26, so that the fixing plate 371 releases the lock bodies, and then the lock bodies are pushed to the unloading channel 11 by the ejector pin 24 for unloading.

[0069] The working principle of the present invention is as follows: the moving block 61 in the driving groove 52 is connected via a linear motor so that it can move linearly in the driving groove 52, and the clamping arm 66 is used to clamp the lock body from the feeding assembly 8. After clamping, the moving block 61 is driven to move toward the assembly table 21, and the assembly table 21 is driven to rotate while moving, and the fixed base 31 is rotated to be parallel to the driving base 51. When the fixed base 31 is about to reach the parallel position of the driving base 51, the bottom engaging base 41 contacts the top column 102 on the lower top plate 10, and squeezes the top column 102 into the top plate 10, and squeezes the telescopic spring 101 inside the top plate 10 at the same time. When the fixed base 31 completely reaches the parallel position of the driving base 51, the top column 102 The notch at the bottom of the meshing base 41 contacts the hexagonal column 42, and then the telescopic spring 101 rebounds to lift the top column 102, and at the same time, the hexagonal column 42 is pushed into the fixed base 31 to engage with the drive shaft 32, and when the hexagonal column 42 is lifted, the meshing gear 43 on the hexagonal column 42 is raised to a certain height, just so that the meshing gear 43 is meshed and connected with the first driven gear 532 on the driving base 51. At this time, the clamping arm 66 also reaches the top of the fixed base 31, and then the telescopic cylinder 65 drives the clamping arm 66 to descend, placing the lock body in the fixed base 31. After placement, the moving block 61 is driven to move away from the fixed base 31 to the feeding assembly 8. When the moving block 61 is away from the fixed base 31, the connecting rod 66 above the moving block 61 is connected to the fixed base 31. The connecting tooth 621 will drive the first driving belt 54 to move. When the first driving belt 54 moves, it will drive the first driving gear 531 and the second driving gear 551 to rotate. The first driving gear 531 will drive the first driven gear 532 on the first driving rod 53 to rotate, and then the first driven gear 532 will drive the meshing gear 43 to rotate. When the meshing gear 43 rotates, it will drive the hexagonal column 42 to rotate. The hexagonal column 42 drives the driving shaft 32 and the crown gear 33 to rotate, and then drives the fixing plate 371 to clamp and fix the lock body. When the moving block 61 reaches the feeding assembly 8, the lock body is fixed, and then the assembly table 21 is driven to rotate, and the fixed base 31 with the lock body is moved to the bottom of the riveting mechanism 7 to install the lock tongue. When the assembly table 21 rotates, the next set of fixed bases 31 without lock bodies are parallel to the driving base 51 again and contact the top column 102. At the same time, the moving block 61 drives the clamping arm 66 and the lock body on the clamping arm 66 to reach the fixed base 31 again. Then the clamping arm 66 places the lock body on the fixed base 31 again. Repeat the above steps to fix the next set of lock bodies. When the clamping arm 66 is away from the feeding table 83, the loading slot 84 on the feeding table 83 is below the storage bin 95. When the clamping arm 66 moves toward the feeding table 83, it drives the first driving belt 54 to move through the connecting teeth 621, and then uses the first driving belt 54 to drive the second driven gear 552 on the second driving rod 55 to rotate.When the second driven gear 552 rotates, the second driving belt 553 will be used to drive the storage gear 92 and the feeding gear 82 to rotate. When the storage gear 92 rotates, the rotating column 93 and the stirring rod 94 in the storage bin 95 will be driven to rotate. When the stirring rod 94 rotates, the lock body will be pushed to the connection between the storage bin 95 and the feeding platform 83. The connection is provided with a notch. When the lock body reaches the notch, it will fall into the loading slot 84 on the feeding platform 83. At the same time, when the feeding gear 82 is rotated by the second driving belt 553, it will drive the feeding platform 83 to rotate, and rotate the loading slot 84 loaded with the lock body to the bottom of the clamping arm 66 at the driving base 51. At this time, the telescopic cylinder 65 drives the clamping arm 66 to descend to clamp the lock body and then move it to the fixed base 31. While moving, the second driving belt 553 is used to drive the storage gear 92 and the feeding gear 82 to rotate, so that the loading slot 84 moves to the bottom of the storage bin 95 to receive the material.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
