Description

Technical Field

[0001] The utility model relates to the technical field of automatic fork materials, in particular to a feeding mechanism for a rivet button automatic press-fitting machine. Background Technique

[0002] In the existing fork lifting mechanism, a lifting mechanism is arranged behind the materials of the feeding linear vibrator. It is applicable to the mechanism of the material height vibration track. However, in actual use, the height of many materials is relatively high. If the track is set relatively low at this time, the materials are prone to tipping. Furthermore, the existing fork mechanism for directly positioning and then lifting the materials cannot be universal for various materials with different heights. Therefore, when actually carrying out fork lifting, it is necessary to design multiple fork lifting mechanisms, which is not conducive to reducing the equipment cost; and when the existing fork lifting mechanism is operating, it can only carry out fork lifting operations individually. For a high-efficiency production line, the efficiency of individual lifting is too low; for this reason, it is urgent to develop a high-efficiency fork lifting mechanism for universal operation.

The top end of the lifting cylinder 41 is fixedly equipped with the lifting and jacking seat 42, and four groups of upward convex jacking rods 43 are arranged on the lifting and jacking seat 42;

[0029] The material limiting mechanism 50 includes a horizontal front and back telescopic cylinder 51 and a cover plate 52,

[0037] The working principle is as follows: The feeding linear vibration conveys the material along the linear track to the end of the track. A stop mechanism (a mature existing technology) is provided at the end. After reaching the quantity N, the stopper in front of the end of the linear track is lowered (a mature existing technology). Then, the pressing heads of the piston push rods of N groups of parallel arranged thimble cylinders press forward and are inserted into the front end opening position of the material, and the top of the material is capped, so that the pressing heads can drive the material to move. The stop mechanism releases the stop. Then, the transverse translation cylinder drives the translation seat body to move to the area directly below the material feeding mechanism, thus completing the material dialing operation. During this period, the pressing cover part is located at the front to perform material pressing operation. After the material is dialed in place, the pressing cover retracts. Then, the jacking cylinder rises to drive the convex lifting rod to drive the material to rise into each feeding clamping area of the material feeding mechanism. The clamping mechanisms in each clamping area of the material feeding mechanism clamp the material. The jacking cylinder drives the convex lifting rod to descend and reset. The transverse translation cylinder drives the translation seat body to reset to the material receiving position. Then, the material dialing and transfer operation is repeated.
