Feed device of minor-diameter rodlike workpiece processing equipment

Abstract

The invention relates to a feed device of minor-diameter rodlike workpiece processing equipment. The feed device comprises a horizontal feed channel, the front end of which is connected with a part of a cutting device; a pushing mandril which is driven by a power unit and can axially move in the feed channel is arranged at the rear section of the feed channel; a feed box is arranged above the feed channel; a discharge port which directly faces the feed channel is arranged at the bottom of the feed box and rodlike workpieces can pass through the discharge port one by one; a guide slope which enables the rodlike workpieces to roll to the discharge port under the actions of gravities is arranged inside the feed box; and the feed box is installed on a vibrating device and can vibrate up and down along with the vibrating device. The feed device has the advantages that: 1, with the feed device, the workpieces with small diameter and light weight can be discharged successfully, clamping stagnation is reduced, and the movement reliability is improved; 2, the strength of the pushing mandril and the structural strength of the entire guide structure are improved, and the fault of breakage of a small-size pushing mandril is reduced.

Description

technical field [0001] The invention relates to a part structure of an automatic equipment for processing small-diameter rod-shaped workpieces (such as drills with a diameter of less than 3 mm), in particular to a feeding device for small-diameter rod-shaped workpiece processing equipment. Background technique [0002] For automatic processing equipment for small-diameter rod-shaped workpieces such as small-diameter twist drills, such as automatic groove grinding machines for small-diameter twist drills, etc., it usually includes a feeding device, a clamping mechanism, a cutting (grinding) device, and an indexing and rotating mechanism. , discharge device and other parts, the feeding device is usually composed of a material box, a material guide groove, a push rod, etc., the bottom of the material box is provided with a discharge port facing the top of the material guide groove, and the rod-shaped blank in the material box can be drawn from the The discharge port at the bott...

AI Technical Summary

Problems solved by technology

In this structure, since the rod-shaped blanks in the magazine rely on gravity to naturally output and fall into the guide groove, for small-diameter workpieces, due to their small diameter and light weight, the falling stability is poor. Often can not fall completely reliably, and may be partially stuck at the discharge port, resulting in malfunction of the equipment

In addition, in this structure, the diameter of the push rod adapted to the diameter of the workpiece is also small, the strength is poor, and it is easy to break during the pushing process, which affects the reliable operation of the equipment
