Description

Automatic assembly machine for lock hook

Technical Field

The invention relates to the technical field of ox horn lock catch assembly machines, in particular to an automatic lock hook assembly machine.

Background

The ox horn lock catch 1 is a locking piece used for the opening of a flip type box body or a box body of a high-grade gift box or a wine box and the like. As shown in fig. 1 to 3, the ox horn latch 1 includes a latch hook 11 and a fixing base 12, and the latch hook 11 includes a bottom plate 13, a latch hook plate 15, a spring 110 and a pin 14. The middle part of the latch hook sheet 15 is provided with a latch bolt 17, the main body end part of the latch hook sheet 15 is provided with a pulling part 16, the fixed seat 12 is provided with a lock hole 18 for the latch bolt 17 to pass through, the latch hook 11 and the fixed seat 12 are respectively arranged at two sides of the opening of the box body when in use, the bottom sheet 13 of the latch hook 11 is fixed on the box body, the latch hook sheet 15 can rotate relative to the bottom sheet 13, so that the latch bolt 17 of the latch hook 11 penetrates into the lock hole 18 of the fixed seat 12, thereby realizing locking. The latch hook piece 15 and the bottom piece 13 are connected through the pin 14, when in assembly, one smaller end of the pin 14 needs to pass through the pin holes 111 on the latch hook piece 15 and the bottom piece 13, the spring 110 is sleeved outside the end, and then the end part of the end is riveted, so that the spring 110, the bottom piece 13 and the latch hook piece 15 are fixed between the two ends of the pin 14. Because the back of the bottom 13 is provided with a cavity 19, the spring is positioned in the cavity 19 after riveting.

The current China patent number 201711482682.4 discloses an automatic clamp assembling machine which comprises a frame, a rotating disc, a clamping piece mounting mechanism, a spring mounting mechanism, a pin pressing mechanism and a material taking mechanism. The number of parts of the latch hook is the same as that of the clip, and the bottom plate, the latch hook sheet and the spring are required to be fixedly assembled when the latch hook is assembled, then the pin penetrates through the bottom plate, the latch hook sheet and the spring, and finally the end part of the pin is extruded, so that the bottom plate, the latch hook sheet and the spring are positioned between the two ends of the pin. However, the clip automatic assembling machine cannot be directly used for installing the lock hook, and the main reasons are as follows: 1. because the upper end and the lower end of the clamping piece are both plane, the clamping piece can be longitudinally stacked when the clamping piece is installed, so that the pin hole is in a vertical state, and then the clamping piece is horizontally pushed into the clamping seat by the pushing rod arranged on the side surface; however, the upper surface and the lower surface of the bottom plate and the latch hook plate are not planar, when the bottom plate or the latch hook plate is longitudinally stacked, two adjacent bottom plates or latch hook plates interfere with each other during pushing, so that the bottom plate or the latch hook plate is blocked and damaged during pushing, and therefore, the clamping piece mounting mechanism in the patent cannot be used for mounting the bottom plate and the latch hook plate of the latch hook. 2. When the clip is assembled, the spring is arranged between the two clamping pieces, the spring of the lock hook is arranged at the lower part of the bottom piece, and the working procedures between the two clamping pieces are different, so that the clamping seat adopted by the clip cannot be suitable for the installation of the lock hook when the clip passes through the clamping piece installation mechanism and then is arranged through the spring installation mechanism. 3. The clip used in this patent is also not suitable for the assembly of the latch hook because the latch hook component and the clip component are different, and the assembly process of the latch hook and the clip is also different, so the structure of the clip of the latch hook also needs to be redesigned. Meanwhile, no automatic machine for assembling with the lock hook exists in the market at present, so that the lock hook can be assembled only manually.
