Technical Field

The invention relates to a steering machine, in particular to an automatic steering machine.

Background

At present, in the sand lined metal mold process, the steering machine for transporting the metal molds is manual, one production worker in one shift needs to turn over the steering machine for more than 900 times, which is quite tired, and the production efficiency is low, and meanwhile, certain potential safety hazards also exist.

Disclosure of Invention

In view of this, the invention aims to provide an automatic steering machine, aiming at overcoming the defects of high labor intensity, low production efficiency, potential safety hazard and the like of the steering machine for transporting iron molds in the existing iron mold sand-lined process.

In order to achieve the purpose of the invention, the technical scheme is as follows:

an automatic steering machine comprises an iron type conveying device, a mechanical linkage device and a driving device which are connected in sequence;

the iron-type conveying device comprises two parallel square steels and a plurality of side rollers, the side rollers are fastened on the square steels through nuts and gaskets, and first connecting plates are welded below the two square steels;

the mechanical linkage device is arranged below the iron-type conveying device and comprises a rotary table, four support legs are symmetrically arranged on the rotary table, second connecting plates are welded on the support legs, and the second connecting plates are connected with the first connecting plates through bolts and nuts;

the driving device is arranged below the mechanical linkage device and comprises a base, and a transmission mechanism and a power mechanism are arranged on the base;

the transmission mechanism is arranged in the middle of the base and comprises a gear shaft, a bearing sleeve and rolling bearings, the bearing sleeve is arranged in the middle of the base, two rolling bearings are arranged in the bearing sleeve along the vertical direction, the gear shaft penetrates through the rolling bearings, one end of the gear shaft is fixed in the center of the turntable, the other end of the gear shaft is connected with the gear, a rack meshed with the gear is arranged at the same vertical height with the gear, and the rack is perpendicular to the gear shaft;

the power mechanism comprises an air cylinder, a speed regulator and a controller, the air cylinder is fixed on the base through a self bolt, the air cylinder is connected with a piston rod, the piston rod is connected with a rack, the piston rod and the rack are arranged along a straight line, the speed regulator is fastened on the air cylinder and connected with a motor of the air cylinder, the speed of the air cylinder can be controlled by the speed regulator, and the controller is electrically connected with the air cylinder and the speed regulator.

Preferably, the controller controls the cylinder to drive the piston rod and the rack to do reciprocating linear motion in the horizontal direction, and meanwhile, the gear meshed with the rack rotates by 90 degrees.

Preferably, the automatic steering machine further comprises a stop iron.

The invention has the beneficial effects that: in the process of transporting the iron mold, when the iron mold needs to rotate by 90 degrees, the controller of the invention is controlled, the control cylinder drives the piston rod and the rack to do reciprocating linear motion, so that the gear meshed with the rack rotates by 90 degrees, meanwhile, the gear shaft connected with the gear drives the turntable to rotate, the iron mold transporting device fixed on the turntable rotates, finally, the iron mold placed on the iron mold transporting device realizes 90-degree rotation, and the rotating speed can be adjusted by the speed regulator. The invention has simple and convenient operation, effectively lightens the labor intensity of workers and improves the working efficiency; one purchase needs thirty-thousand yuan, while six thousand yuan is needed for making the invention, thus greatly reducing the production cost.
