Embodiment 1

[0022] Such as figure 1 , 2 As shown, the automatic direction-selecting transfer mechanism for the expansion screw blank is arranged at the discharge end of the vibrating tray 1. The transfer mechanism 9 includes two parallel and transversely arranged conveying shafts 2, between the two conveying shafts 2 Form conveying channel 3, one end of conveying channel 3 is connected with the discharge end of vibrating tray 1, and the other end extends laterally outwards, and the width of conveying channel 3 is less than the outer diameter of convex ring 41 that is arranged on the expansion screw blank 4 near the upper end and expands. The center of gravity of the screw blank 4 is located between the convex ring 41 and the lower end of the expansion screw blank 4, and the width of the conveying channel 3 is larger than the outer diameter of the rest of the expansion screw blank 4. During the passage 3, each expansion screw blank 4 is automatically adjusted to a vertical state under the...

Embodiment 2

[0028] Such as image 3As shown, in this embodiment, the stripping structure 5 includes two opposite side grooves 51 arranged on two conveying shafts 2, and the sum of the width of the conveying channel 3 and the depth of the two side grooves 51 is greater than that of the convex ring 41 outer diameter, the width of the side groove 51 is greater than the outer diameter of the protruding ring 41 and less than twice the outer diameter of the protruding ring 41 . The rest are similar to those in Example 1, and will not be described in detail herein.

Abstract

The invention belongs to the technical field of machining of expansion screws, and in particular, relates to an automatic direction selecting transfer mechanism of an expansion screw blank. The mechanism comprises two conveying shafts transversely arranged in parallel; a conveying channel is formed between the two conveying shafts; one end of the conveying channel is connected with a discharge end of a vibration tray, and the other end transversely extends outwards; the width of the conveying channel is smaller than the outer diameter of a convex ring arranged on the expansion screw blank near the upper end; the gravity center of the expansion screw blank is positioned between the convex ring and the lower end of the expansion screw blank; the width of the conveying channel is larger than the outer diameter of the rest part of the expansion screw lank; and when the expansion screw blank output by the discharge end of the vibration tray enters the conveying channel, each expansion screw blank is automatically adjusted in a vertical state under the effect of gravity, and the lower end of each expansion screw blank is positioned below the conveying channel. Compared with the prior art, the automatic direction selecting transfer mechanism for the expansion screw blank has the advantages of reasonable design, high automation degree and capability of saving labors.

Description

technical field [0001] The invention belongs to the technical field of expansion screw processing, and relates to a conveying device, in particular to an automatic direction-selecting transfer mechanism for expansion screw blanks. Background technique [0002] Expansion screws are generally referred to as metal expansion screws. The expansion screw is fixed by using the wedge-shaped slope to promote the expansion to generate friction and grip force to achieve the fixing effect. The screw is threaded at one end and tapered at the other end. Wrapped with an iron sheet (some are steel pipes) on the outside, there are several cuts in the half of the iron sheet cylinder (steel pipe), stuff them together into the hole punched in the wall, and then lock the nut, the nut pulls the screw outward, and pulls the taper into the iron sheet cylinder , the iron cylinder is stretched open, so it is tightly fixed on the wall, and is generally used for fastening fences, awnings, air conditio...
