Description

Technical Field

[0001] This utility model relates to the field of intelligent door lock assembly equipment components, and in particular to an automatic tooth-pulling mechanism for a semi-automatic intelligent lock line. Background Technology

[0002] A smart lock is a type of lock that differs from traditional mechanical locks in that it is more intelligent in terms of user identification, security, and management. A smart lock is the locking mechanism in an access control system. Electronic locks cannot be called smart locks; the intelligence of a smart lock is demonstrated by its ability to be remotely controlled via smartphone and integrated with smart home systems.

[0003] In some smart door locks, the clutch is a key mechanical component. The clutch connects the handle to the lock body and controls the opening and closing of the lock. The assembly process for this clutch requires the assembly and fixing of multiple components, including... Figure 1 As shown, the protruding teeth on the front round tube of the clutch will pass through the through holes on the front paddle during assembly. The exposed part of the protruding teeth needs to be bent laterally so that the front round tube and the front paddle can be connected and fixed together. Since most assembly lines are currently operated by stamping mechanisms, which use a straight up and down stamping method, the protruding teeth need to be bent in advance. However, this will increase the lateral profile size of the protruding teeth, increase the difficulty of pre-installation, and easily cause incomplete loading, resulting in poor stamping effect and defective products. Utility Model Content

[0004] This utility model provides an automatic tooth-shifting mechanism for a semi-automatic intelligent lock line, which helps to solve the problem of difficult pre-installation and unstable tooth quality caused by the use of a straight up-down stamping mechanism for the tooth shifting of the front round tube protrusion in the lock body clutch.

[0005] This utility model is implemented as follows:

[0006] An automatic tooth-gripping mechanism for a semi-automatic intelligent lock production line includes a support, a lifting module on the support, a first slider that can slide up and down along the front side wall of the support, a tooth-gripping assembly connected to the front side of the first slider, the tooth-gripping assembly including a base plate connected to the first slider, a transverse stamping mechanism on the base plate, the transverse stamping mechanism including a transverse drive, a transverse slider and a tooth-gripping block, the bottom of the tooth-gripping block having a groove adapted to the contour of the workpiece to be toothed, the lifting module and the transverse stamping mechanism each having a stroke limit structure, and the transverse stamping mechanism also having a stroke buffer structure.

[0007] Based on the above technical solution, the support includes an "L"-shaped frame structure, with mounting holes for connecting external mechanisms on its bottom horizontal plate, and ribs on the rear side of the support.

[0008] Based on the above technical solution, the first slider is connected to a lifting cylinder at the top, the main body of the lifting cylinder is fixedly connected to the top of the support, and a vertically arranged slide rail is provided between the first slider and the front side wall of the support, so that the first slider can slide linearly up and down along the slide rail.

[0009] Based on the above technical solution, the first slider has raised edges on both the left and right sides, and the support is located directly below the raised edges and has a first buffer and a limiting rod.

[0010] Based on the above technical solution, a first positioning switch is provided between the top of the first slider and the support.

[0011] Based on the above technical solution, two transverse stamping mechanisms are provided on the front sidewall of the substrate.

[0012] Based on the above technical solution, the bottom of the toothed block is provided with a protrusion, the inner side of the protrusion is a flat end face and the bottom corner of the inner side is provided with a chamfer structure, and the slot is located at the outer side of the protrusion.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This invention utilizes a support structure, on which a lifting module and a transverse stamping module are mounted. During operation, the lifting module lowers the transverse stamping module to a designated height. The transverse stamping module, using a toothed block, abuts against the workpiece after reaching its designated position. Applying force, the transverse stamping module uses the toothed block as a punch to laterally stamp the workpiece, achieving the desired processing effect. This automated mechanical structure effectively solves the problems of difficult pre-installation and unstable tooth quality in the front cylindrical protrusion teeth of the lock body clutch, which are often caused by a straight-up-down stamping mechanism.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Combination Figure 2-7 This embodiment discloses an automatic tooth-bending mechanism for a semi-automatic intelligent lock line, which aims to solve the problem that most assembly lines currently use stamping mechanisms for operation. Stamping mechanisms use a straight up-down stamping method, which requires the protruding tooth b to be bent in advance. However, this will increase the lateral profile size of the protruding tooth b, increase the difficulty of pre-installation, and easily cause incomplete loading, resulting in poor stamping effect and defective products.

[0031] In this embodiment, the automatic tooth-gripping mechanism specifically includes a support 1, a first slider 2, an extension block 3, a base plate 4, a second slider 5, and a tooth-gripping block 6.

[0032] The support 1 includes an "L"-shaped frame structure, with mounting holes 11 on its bottom horizontal plate for connecting external mechanisms. The mounting holes 11 are strip-shaped through holes to facilitate adjustment of the installation position. Ribs 12 are also provided on the rear side of the support 1. The support mainly serves to bear and support loads.

[0033] Combination Figure 4The support 1 is equipped with a lifting module, which includes a first slider 2 that can slide up and down along the front sidewall of the support 1. The top of the first slider 2 is connected to a lifting cylinder 22, and the body of the lifting cylinder 22 is fixedly connected to the top of the support 1. A vertically arranged slide rail 21 is provided between the first slider 2 and the front sidewall of the support 1, allowing the first slider 2 to slide linearly up and down along the slide rail 21. Furthermore, the first slider 2 has raised edges 24 on its left and right sides. The support 1 is equipped with a first buffer 25 and a limiting rod 26 directly below the raised edges 24. The first buffer 25 prevents the first slider 2 from being excessively pressed down, and the limiting rod 26 is a rigid structure that serves as a forced constraint structure at the bottom of the stroke of the first slider 2. Furthermore, a first position switch 23 is provided between the top of the first slider 2 and the support 1. The first position switch 23 is used to precisely control the initial position of the first slider 2.

[0034] The front side of the first slider 2 is connected to a toothed assembly. The toothed assembly includes a base plate 4 connected to the first slider 2. The base plate 4 is a vertically arranged plate structure. The rear side of the base plate 4 is connected to the first slider 2 through two left-right spaced extension blocks 3. The front side wall of the base plate 4 is provided with two left-right symmetrically arranged transverse stamping mechanisms.

[0035] In this embodiment, the transverse stamping mechanism includes a transverse drive, a transverse slider (second slider 5), and a toothed block 6. The bottom of the toothed block 6 is provided with a groove 62 adapted to the contour of the workpiece to be toothed. Figure 5 The main body of the transverse cylinder 51 is connected and fixed to the base plate 4. The telescopic rod of the transverse cylinder 51 is horizontally inward and connected to the second slider 5. The transverse inner end of the second slider 5 is connected to the tooth block 6. The bottom of the tooth block 6 extends to the bottom of the second slider 5, serving as the main end of the stamping tooth operation.

[0036] Furthermore, in combination Figure 6 The bottom of the toothed block 6 is provided with a protrusion 61. The inner lateral end of the protrusion 61 is a flat end face, and the bottom inner corner is provided with a chamfer structure. This makes the downward movement of the toothed block 6 and its upward movement after stamping smoother, reducing the occurrence of accidental interference. The slot 62 is located at the outer lateral end of the protrusion 61. The inner end face of the slot 62 is a curved surface structure adapted to the tooth b. (Refer to...) Figure 1 and Figure 7 .

[0037] To prevent the downward movement of the wrench assembly from accidentally squeezing the workpiece, a vertical elastic pressure bar 41 is provided at the bottom of the base plate 4. After the elastic pressure bar 41 comes into contact, it will adapt to different degrees of elastic movement, which is also conducive to providing a stable pressing effect on the workpiece, making the wrench operation more stable and reliable.

[0038] Combination Figure 5The transverse outer end of the transverse slider is provided with a second positioning switch 52. The function of the second positioning switch 52 is to precisely control the outer position of the tooth block 6 so that it can accurately engage with the protruding tooth b. The transverse inner end of the transverse slider is provided with a second buffer 53, which helps to prevent the tooth block 6 from moving too inward and can play a certain role in protecting the transverse stamping structure.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
