The padlock is used as a traditional lockset, and a lock body of the padlock is provided with a buckled annular or straight-line-shaped metal stem, namely a 'lock beam', so that the padlock is directly buckled with the lock body through the lock beam to form a closed lockset. The padlock comprises a lock body 9 and a lock beam, as shown in fig. 1, the lock body is provided with a lock beam shallow hole 91, a lock beam deep hole 92, a lock bolt hole 93, a lock cylinder hole 94, a vertical milling spring hole 95 and a spring hole 96, wherein the lock beam shallow hole 91 is communicated with the lock cylinder hole 94 through the lock bolt hole 93, the lock cylinder is arranged in the lock cylinder hole 94, a lock bolt 97 and a lock bolt 98 are arranged in the lock bolt hole 93, a lock bolt groove 971 is arranged in the middle of the lock bolt, a lock cylinder pin 991 on the end part of the lock cylinder 99 hooks the lock bolt groove 971 on the lock bolt, and a vertical milling spring is inserted into the vertical milling spring hole 95 of the lock body and is clamped in the vertical milling spring groove on the lock cylinder to prevent the lock cylinder. The two ends of the lock beam are respectively arranged in the lock beam shallow hole 91 and the lock beam deep hole 92, a buckling relation is formed between the lock bolt and the end part of the lock beam in the lock beam shallow hole 91, and when the lock is used, the lock bolt is controlled to move by controlling the lock core to rotate through a key, so that unlocking and locking actions are realized. In the installation, the installation of the lock beam is the last process of padlock assembly, and the preorder assembly action comprises the installation of a lock tongue spring, the installation of a lock tongue, the installation of a lock cylinder, the installation of a vertical milling bullet and the like. At present, in the existing assembly production of the padlock, a lock tongue and a lock tongue spring are firstly put into a lock tongue hole 93 of a lockset by manpower, positioned and installed by using an end milling marble, and then taken to a lockset assembly machine to continuously install accessories such as marbles and the like. In the traditional process, the lock tongue and the lock tongue spring are manually assembled, and the assembling efficiency is low.
The automatic bolt assembling machine comprises a bolt hole positioning mechanism, a bolt spring assembling mechanism, an end milling hole positioning mechanism and an end milling bullet assembling mechanism, wherein a lockset is arranged in a lock body clamp and is driven by a turntable to pass through the four mechanisms in sequence; when the lock bolt hole positioning mechanism is used, the positioning assembly of the station positions and aligns the lock bolt hole of the lock, and then the driving assembly acts on the driving part to enable the lock body clamp to clamp the lock; the lock tongue and the lock tongue spring are installed on a lock tongue and lock tongue spring assembling mechanism; when the hole positioning mechanism is milled vertically, the positioning assembly of the station positions and aligns the lock bolt hole of the lock, and then the driving assembly acts on the driving part to enable the lock body clamp to clamp the lock; in the end milling bullet assembly mechanism, the end milling bullet is installed, and the spring bolt can be prevented from falling off after the end milling bullet is installed. By the automatic spring bolt assembling machine, on one hand, high-precision assembling of the spring bolt can be realized, and assembling quality is improved; on the other hand, the efficient assembly of the lock tongue can be realized, and the assembly efficiency is improved. However, the automatic lock tongue assembling machine adopts a scheme that the rotating disc and the lock body clamp thereon are used for conveying the lock body, so that the lock tongue hole positioning mechanism, the lock tongue and lock tongue spring assembling mechanism, the end milling hole positioning mechanism and the end milling ball assembling mechanism are required to be arranged around the rotating disc, and compared with the prior art, the automatic lock tongue assembling machine is complex in structure and relatively large in size.
Further, the technical solution of the above prior application describes an assembly structure of a tongue as follows: the lock tongue and lock tongue spring assembling mechanism comprises a support, and an assembling cylinder, a lock tongue feeding device and a lock tongue spring feeding device which are arranged on the support; the support is provided with an assembly opening, the assembly cylinder is arranged above the assembly opening, and the output end of the assembly cylinder faces the assembly opening. The assembling mechanism synchronously installs the lock tongue and the lock tongue spring, and the lock tongue hole can be aligned by one-time positioning during installation, so that the assembling process is saved, transposition between different mechanisms is avoided, and the assembling efficiency is improved. During assembly, the lock tongue is input by the lock tongue feeding clamp and clamped, and the lock tongue feeding pair pushes the lock tongue to the upper part of the assembly opening; the locking tongue spring is input from a locking tongue spring feeding port and clamped, and the locking tongue spring feeding pair pushes the locking tongue spring to the upper part of the assembling port; because the output path of the spring bolt feeding pair is positioned below the output path of the spring bolt feeding pair, the spring bolt and the spring bolt are sequentially positioned on the output path of the assembly cylinder from top to bottom at the moment, and the spring bolt are synchronously pushed into a spring bolt hole of the lock through the assembly port during the output of the assembly cylinder, so that the assembly is completed. However, the above scheme does not describe how to standardize the direction of the lock tongue in the loading process, and because the lock tongue pins and the lock tongue grooves need to be hooked when the lock tongue is assembled with the lock core, the scheme does not describe how to limit the direction of the lock tongue, so that further optimization is needed.
In addition, when the lock core is assembled, the lock core is assembled into the lock core hole of the lock body through an assembling machine, but a plurality of lock cores have two sections, namely, one end of the lock core has a larger step; when the lock cylinder is fed, the lock cylinder needs to be tightly positioned, so that the lock cylinder clamp needs to be attached to the small-size end face of the lock cylinder, but the lock cylinder cannot pass through the lock cylinder clamp; therefore, improvements are urgently needed.
