Description

Technical Field

[0001] The present invention belongs to the technical field of lock production and assembly, and in particular relates to a lock assembly machine and an assembly method. Background Art

[0002] As a safety protection device widely used in various places, the quality and performance of locks are directly related to the safety of the places of use. In modern industrial production, in order to improve the production efficiency of locks and ensure the consistency of product quality, lock assembly machines came into being. Lock assembly machines are a type of equipment specially used to automatically assemble various lock accessories, such as lock cylinders, lock tongues, handles, etc. Assembly through lock assembly machines can not only greatly improve production efficiency and reduce labor costs, but also effectively reduce assembly errors caused by human factors, ensuring that each lock meets strict quality standards. Therefore, in the large-scale production process of locks, the use of lock assembly machines for assembly is an indispensable link.

[0003] At present, the existing lock assembly machines have many shortcomings and deficiencies in actual use. In the lock assembly process, the placement and positioning of the lock body is a key link. Since the existing assembly machines lack an effective positioning mechanism, the lock body is often unstable when placed, which makes the lock body easy to shift during assembly. This shift will significantly affect the installation of other accessories, making it impossible for the accessories to be accurately installed in the predetermined position, thereby causing the problem of improper installation of the accessories, seriously affecting the overall assembly quality and performance of the lock; and the lock body has a variety of different shapes, and different models of lock bodies have differences in size, shape, etc., and the existing lock assembly machines lack the assembly limit function for different models of lock bodies, and cannot adapt to the assembly requirements of lock bodies of different shapes. They can only assemble lock bodies of specific models, which greatly limits the versatility and applicability of the lock assembly machines; therefore, there are deficiencies and cannot meet the assembly and use requirements of manufacturers. Therefore, it is necessary to further improve them.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lock assembly machine and assembly method are provided to achieve a more practical purpose. Summary of the Invention

A positioning mechanism for assembling and positioning the lock body is fixedly mounted on the transmission assembly. The bearing assembly includes a bearing plate for carrying the lock body to be assembled. The bearing plate is driven downward by the lock body under the action of gravity, which can drive the transmission assembly to drive the positioning mechanism to perform adaptive locking and positioning on the lock body. The positioning mechanism includes a positioning seat, on which a first positioning component is movably mounted, and on which a second positioning component is movably mounted. The first positioning component and the second positioning component can be adaptively fitted and positioned according to the shape of the lock body.

In the process of clamping the lock body, it can adaptively adjust to the position with the largest contact area with the outer wall of the lock body and the most stable force, forming the most reliable positioning state. This adaptive positioning mechanism greatly improves the accuracy and stability of the lock body positioning, so that the lock body can maintain a stable position during the subsequent assembly process, effectively avoiding the assembly errors and low assembly efficiency caused by inaccurate positioning. At the same time, the design is highly flexible and adaptable, and can automatically adapt to lock bodies of different shapes without the need for frequent replacement of lock body positioning tools.

[0014] As a further description of the above technical solution: the design of pushing the support slider to slide on the support seat through the support connecting rod effectively disperses the downward pressure of the transmission screw and the supporting plate, making the pressure on the supporting plate and the lock body more uniform, further improving their stability. This stable support structure provides a solid foundation for the precise assembly of the lock body.

[0015] Furthermore, a plurality of first movable grooves are provided inside the positioning seat, and a first limiting groove is also provided inside the positioning seat, and the first limiting groove is located in the first movable groove.

[0018] As a further description of the above technical solution: through the movement characteristic of the first positioning tooth that can rotate along the obstacle point when subjected to force, the first positioning tooth is driven to rotate in the first movable groove, so that the first positioning tooth can adaptively rotate to the position with the largest contact area with the outer wall of the lock body and the most stable force, thereby forming the most stable positioning state.

[0019] Furthermore, the second positioning assembly includes a second positioning tooth movably assembled in a second movable groove, a second movable shaft is rotatably mounted on the second positioning tooth, second limiting members are fixedly mounted on the upper and lower sides of the second positioning tooth, and the second limiting member is located in the second limiting groove.

[0021] Furthermore, the rotating assembly includes a rotator fixedly mounted on the frame, and a working platform for multi-station assembly conversion of the lock body is fixedly mounted on the upper side of the rotator; A control panel for controlling the equipment is fixedly mounted on the machine base.

[0022] As a further description of the above technical solution: the lock body is automatically shifted at multiple assembly mechanism stations to achieve automatic assembly of the lock body. Through this multi-station automatic shifting setting, the lock body can complete different assembly processes in sequence at different stations, thereby achieving continuous and efficient assembly of the lock.

[0023] A lock assembly method comprises the following steps: S1: First, place the lock body to be assembled on the bearing plate in the assembly seat; S2: The lock body exerts downward pressure on the load-bearing plate due to its own gravity, and the load-bearing plate moves downward while driving the transmission screw to move downward synchronously; S3: By moving the transmission screw downward, the screw thread of the transmission screw and the transmission gear rotates to drive the transmission gear to rotate. S4: The transmission gear and the transmission rack are meshed to drive the transmission rack to drive the transmission block, the transmission column and the positioning seat to move relative to each other, so that the positioning seat can automatically clamp and position the lock body; S5: The first positioning tooth and the second positioning tooth are then in contact with the outer wall of the lock body, and the first positioning tooth and the second positioning tooth are adaptively rotated to a position where the contact area with the outer wall of the lock body is maximized and the force is most stable; S6: Finally, the work platform is driven to rotate by the rotator, and the work platform is used to drive the assembly seat and the firmly positioned lock body to automatically change positions in multiple assembly mechanism stations to achieve automatic assembly of the lock body.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This lock assembly machine uses the weight of the lock body as the driving force, and through the coordinated action of the transmission screw, transmission gear, and transmission rack, the positioning seat realizes the automatic clamping and positioning of the lock body, and can rotate along the obstacle point when the first positioning tooth and the second positioning tooth are subjected to force. In the process of clamping the lock body, it can adaptively adjust to the position with the largest contact area with the outer wall of the lock body and the most stable force, forming the most reliable positioning state. This adaptive positioning mechanism greatly improves the accuracy and stability of the lock body positioning, so that the lock body can maintain a stable position during the subsequent assembly process, effectively avoiding the assembly errors and low assembly efficiency caused by inaccurate positioning. At the same time, the design is highly flexible and adaptable, and can automatically adapt to lock bodies of different shapes. There is no need to frequently replace the lock body positioning tool, which greatly saves assembly time and cost, improves production efficiency and product quality, and provides a strong guarantee for the large-scale and efficient assembly of locks.

[0025] 2. During the rotation of the first positioning tooth and the second positioning tooth, the lock assembly machine drives the first limiting member and the second limiting member to rotate synchronously in the corresponding first limiting groove and the second limiting groove respectively. The rotation of the first limiting member in the first limiting groove effectively limits the rotation angle of the first positioning tooth, and the rotation of the second limiting member in the second limiting groove effectively limits the rotation angle of the second positioning tooth. This rotation angle limiting mechanism ensures that the first positioning tooth and the second positioning tooth will not rotate excessively during the adjustment process, thereby ensuring that they can always remain in a reasonable positioning range, improving the stability and accuracy of positioning. At the same time, this design enables the device to adapt to lock bodies of more different shapes and sizes, further expanding its application range, and meeting the diverse needs of different customers for lock assembly.

[0026] 3. This lock assembly machine provides a stable supporting force for the load-bearing plate through the elastic force of the support spring and the load-bearing spring. When the lock body is placed on the load-bearing plate, the load-bearing spring and the support spring can effectively buffer the gravity impact of the lock body and ensure the stability of the load-bearing plate. At the same time, the design of the support connecting rod pushing the support slider to slide on the support seat effectively disperses the downward pressure of the transmission screw and the load-bearing plate, making the pressure on the load-bearing plate and the lock body more uniform, further improving their stability. This stable support structure provides a solid foundation for the precise assembly of the lock body. During the assembly process of the lock body, any slight shaking or instability may lead to assembly errors, affecting the performance and quality of the lock. This device effectively reduces vibration and shaking during the assembly process by optimizing the support structure, improves the assembly accuracy of the lock body, and ensures the reliability and safety of the lock.

[0040] A lock assembly method comprises the following steps: S1: First, place the lock body to be assembled on the carrying plate 41 in the assembly seat 30; S2: The lock body exerts downward pressure on the carrier plate 41 due to its own gravity, and the carrier plate 41 moves downward while driving the transmission screw 51 to move downward synchronously; S3: The transmission screw 51 moves downward, causing the screw 51 and the transmission gear 52 to rotate with each other. S4: The transmission gear 52 and the transmission rack 53 are meshed with each other, so that the transmission rack 53 drives the transmission block 54, the transmission column 55 and the positioning seat 71 to move relative to each other, so that the positioning seat 71 can automatically clamp and position the lock body; S5: The first positioning tooth 721 and the second positioning tooth 731 are in contact with the outer wall of the lock body, and the first positioning tooth 721 and the second positioning tooth 731 are adaptively rotated to a position where the contact area with the outer wall of the lock body is the largest and the force is the most stable; S6: Finally, the rotator 21 drives the working platform 22 to rotate, and the working platform 22 drives the assembly seat 30 and the firmly positioned lock body to automatically change positions at multiple assembly mechanism 12 stations to achieve automatic assembly of the lock body.

[0041] The specific usage and function of this embodiment are as follows: Working principle: When in use and during the assembly process of the lock, the lock body to be assembled is first placed on the supporting plate 41 in the assembly seat 30. The lock body exerts downward pressure on the supporting plate 41 due to its own gravity. This pressure is transmitted to the supporting spring 42 and the elastic pad 43 in turn, causing the supporting plate 41 to move downward, and the supporting plate 41 moves downward while driving the transmission screw 51 to move downward synchronously, and the lower end of the transmission screw 51 is used to push the support block 64 to move downward synchronously, prompting the supporting link 63 to push the supporting slider 62 to slide on the support seat 61 and squeeze the supporting spring 66 at the same time. In this process, the supporting spring 66 and the elastic force of the supporting spring 42 work together to provide a stable supporting force for the supporting plate 41, and the sliding of the supporting slider 62 by the supporting link 63 effectively disperses the downward pressure borne by the transmission screw 51 and the supporting plate 41, thereby significantly improving the stability of the supporting plate 41 and the lock body. In addition, as the transmission screw 51 continues to move downward, the transmission gear 52 can be driven to rotate by the threaded rotation effect of the transmission screw 51 and the transmission gear 52, and the meshing transmission of the transmission gear 52 and the transmission rack 53 is used to drive the transmission rack 53 to drive the transmission block 54 to move toward the transmission gear 52, and the movement of the transmission block 54 drives the transmission column 55 and the positioning seat 71 to move relative to each other, so that the positioning seat 71 can achieve the clamping and positioning action of the lock body. At the same time, in the process of the positioning seat 71 clamping the lock body, the first positioning tooth 721 and the second positioning tooth 731 are driven to fit and contact with the outer wall of the lock body. Based on the motion characteristics of the first positioning tooth 721 and the second positioning tooth 731 that can rotate along the obstacle point when subjected to force, the first positioning tooth 721 is driven to rotate in the first movable groove 711. When the second locking cam 731 is in the unlock state, the locking cam 731 is in the unlock state, and the second locking cam 731 is in the unlock state, so the second locking cam 731 is locked. In addition, during the rotation of the first positioning tooth 721 and the second positioning tooth 731 in the first movable groove 711 and the second movable groove 7211, the first positioning tooth 721 simultaneously drives the first limiting member 723 to rotate synchronously in the first limiting groove 712, and the second positioning tooth 731 simultaneously drives the second limiting member 733 to rotate synchronously in the second limiting groove 7212. The first limiting member 723 is rotated in the first limiting groove 712 to effectively limit the rotation angle of the first positioning tooth 721, and the second limiting member 733 is rotated in the second limiting groove 7212 to effectively limit the rotation angle of the second positioning tooth 731. This arrangement further improves its applicability. And when the lock body is firmly positioned, the rotator 21 drives the working platform 22 to rotate, and the working platform 22 drives the assembly seat 30 and the firmly positioned lock body to automatically shift positions at multiple assembly mechanism 12 stations, thereby realizing automatic assembly of the lock body. Through this multi-station automatic shifting setting, the lock body can complete different assembly processes in sequence at different stations, realizing continuous and efficient assembly of the lock.
