Feeding mechanism for shafts and machine tool head adopting same

Abstract

A feeding mechanism for shafts comprises a work bin, a feed plate, a first air cylinder, a material dialing plate, a second air cylinder, a material ejection plate and a third air cylinder, wherein the work bin is provided with a discharge port only allowing one workpiece to pass at a time; the feed plate is arranged below the work bin, used for undertaking the workpiece coming down the discharge port, and provided with a strip-shaped groove; the power output terminal of the first air cylinder is connected with the feed plate, and can drive the feed plate to move forth and back; the power output terminal of the second air cylinder is connected with the material dialing plate; the material ejection plate is arranged in parallel to the length direction of the strip-shaped groove; and the power output terminal of the third air cylinder is connected with the material ejection plate, and can drive the material dialing plate to move forth and back. Compared with the prior art, the feeding mechanism has the advantages that the operation continuity is excellent, the material leakage and malposition rates are small, the over-all structure is simple and compact, and the installation volume is small; and the feeding mechanism is suitable for being arranged on a numerical control processing machine tool for the shafts.

Description

technical field [0001] The invention relates to a feeding mechanism, in particular to a shaft feeding mechanism, which can be applied to the machine head of a numerically controlled machine tool. The invention also discloses a machine head using the feeding mechanism. Background technique [0002] Production and processing of shafts is common in various mechanical manufacturing fields. The production process of shaft processing generally includes two processes of feeding and processing, in which the feeding process directly determines the level of production efficiency. The traditional shaft feeding is mainly carried out by manual operation, which is time-consuming and labor-intensive, and the production efficiency is low. In order to effectively solve this problem, related feeding machines have been developed in the industry. Most of these machines have defects and deficiencies such as complex structure, poor feeding continuity, and unadjustable feeding speed. [0003] T...

Problems solved by technology

The traditional shaft feeding is mainly carried out by manual operation, which is time-consuming and labor-intensive, and the production efficiency is low

In order to effectively solve this problem, related feeding machines have been developed in the industry. Most of these machines have defects and deficiencies such as complex structure, poor feeding continuity, and unadjustable feeding speed.

[0003] The prior art discloses an improved feeder specifically for shafts, see the Chinese utility model patent "A Slender Shaft Feeder" with the patent number ZL201120362495.4 (the authorized announcement number is CN202296351U), the patent includes The upper part of the frame is equipped with a sloping plate for filling materials, and a slideway is vertically provided on one side of the frame. The lower side of the sloping plate for storing materials is provided with a feeding port, and the feeding port is connected with the slideway; the slideway can slide up and down. There is a slide plate, and there is a conveyor belt outside the side of the frame with a slideway. The conveyor belt is set in parallel with the slideway, and the energy is continuously fed to the shaft through the up and down movement of the slider, which greatly improves the production efficiency. This patent adopts the transmission To the transmission, the overall volume is large and the structure is relatively cumbersome, so it is not suitable for use on CNC shaft processing machine tools. Since the head space of the machine tool is relatively narrow, the above-mentioned disclosed feeder cannot be installed and installed. Therefore, it is necessary to develop a small and convenient Feeder installed and suitable for CNC shaft processing machine tools
