Automatic screw rod feeding device

Abstract

The invention provides an automatic screw rod feeding device which comprises a machine frame with a worktable, a quick-replaced material box, a feeding part and a material pushing part. The quick-replaced material box is arranged on the worktable of the machine frame and used for carrying screw rods to be conveyed; the feeding part is disposed on the worktable of the machine frame, is in butt joint with the quick-replaced material body and comprises a temporary material storing area and a sliding table of a sliding area, a first blocking element is arranged between the temporary material storing area and the sliding area in a convex mode, a material pushing through groove is formed in the tail end of the temporary material storing area and located in the first blocking element position, a discharging opening is formed in the tail end of the sliding area, and a second blocking element is disposed on the discharging opening; the material pushing part comprises a first-stage wedge angle push plate and a second-stage wedge angle push plate, the two push plates can be driven by a drive mechanism to move vertically, the first-stage wedge angle push plate is vertically arranged on the butt joint portion of the material box and the sliding table, and the second-stage wedge angle push plate is vertically inserted into the material pushing through groove. The automatic screw rod feeding device overcomes the defects that in the prior art, directional feeding of screw rods with special head characteristics is difficult, conveying efficiency is low, and the successful rate of directional feeding is low.

Description

technical field [0001] The invention relates to the technical field of feeding equipment, in particular to an automatic feeding device for small-sized screw rods. Background technique [0002] In the field of mechanical processing technology, the transmission of workpieces and materials is often involved. At present, there are many feeding processes and devices, such as the patent document published by the Chinese Patent Office: ZL200720005336.2, which involves a cam-type inclined push plate feeding process. There is a push plate combination, which has a synchronous lower push plate and an upper push plate combined into one body, and a middle push plate sandwiched between the lower and upper push plates, and reverse symmetrical cam grooves are provided on both sides of the cam by means of a cam , and combined with a swing arm, the inner edge of the roller walking groove at the end of the arm produces up and down swings in reverse timing, thereby driving the upper and lower p...
