Description

Workpiece conveying equipment

Technical Field

The invention relates to the technical field of workpiece transportation, in particular to workpiece transportation equipment.

Background

The workpiece refers to a processing object in a machining process. The workpiece machining device can be a single part or a combination of a plurality of fixed parts, the machining modes of the workpiece are various, such as turning, milling, planing, grinding, casting, forging and the like, and the machining procedures of the workpiece are changed along with the change of the machining modes.

In general, a work is initially a blank, and the blank is processed through a process such as grinding to form a molded work. Blank generally can adopt the shallow to transport to processing equipment such as equipment of polishing, and the shallow mainly includes the automobile body and installs the gyro wheel in the automobile body bottom, installs on the automobile body and pushes away the handle, and operating personnel packs the blank into the automobile body in, then pushes away the shallow to processing equipment such as equipment of polishing through pushing away the handle, and consequently current shallow structural function is comparatively single, and in the transportation, the shallow can't process the work piece, and is less to the machining efficiency influence of work piece promptly.

Disclosure of Invention

The invention aims to provide workpiece conveying equipment which is used for partially processing a workpiece in the workpiece conveying process so as to improve the processing efficiency of the workpiece.

In order to achieve the purpose, the invention provides the following technical scheme: a workpiece conveying device comprises a frame and a supporting shaft fixed on the frame, wherein a plurality of placing groups are arranged on the supporting shaft;

the placing plate comprises an upper plate and a lower plate, the upper plate and the lower plate can be detachably connected with the supporting shaft, an inclined upper placing groove is formed in the upper plate, an inclined lower placing groove is formed in the lower plate, the inclination directions of the upper placing groove and the lower placing groove are opposite, and a pipe fitting for communicating the upper plate and the lower plate is arranged between the lower end of the upper placing groove and the high end of the lower placing groove;

the upper portion of pipe fitting is provided with the roller of polishing of being connected with the upper plate rotation, and the roller of polishing is fixed with the slave gear coaxially, is fixed with the driving piece on the back shaft, is fixed with the master gear with slave gear meshing coaxially on the output shaft of driving piece.

The principle and the beneficial effects of the invention are as follows: (1) use work piece transportation equipment to transport the work piece, can polish processing, specific to the work piece in the transportation: place the work piece in the last standing groove of upper plate, the grinding roller work is beaten in the driving piece drive, and the work piece is when beating the grinding roller, and the grinding roller is tentatively polished the work piece, so reaches the in-process of work piece transportation, the purpose of processing. Through the polishing processing during the transportation, when the work piece is polished and is processed, can reduce the process time of the equipment of polishing, and then improve the machining efficiency of work piece.

(2) The work piece after polishing, under the effect of gravity, the work piece can move the least significant end of supreme standing groove, then enters into through the pipe fitting and places the inslot under, and under the effect of gravity, the work piece can move to the least significant end of putting down the groove and concentrate, so the operating personnel of being convenient for collect the work piece.

(3) Because upper plate and hypoplastron can be dismantled with the back shaft and be connected, when the quantity of work piece was too much, can dismantle the work next shift of collecting full, then change other hypoplastron and continuously collect the work piece. When the upper plate or other components have faults, the upper plate and the lower plate are detached, so that an operator can conveniently maintain the upper plate or other components.
