Pure pneumatic sand core full-automatic transferring sling

Abstract

The invention discloses a pure pneumatic sand core full-automatic transferring sling which comprises a hoisting ring, an overturning connecting rod and an opening-closing air cylinder, wherein the hoisting ring is fixedly arranged in the middle of the top side of a cross beam; positioning plate lifting air cylinders are arranged on the cross beam on the two sides of the hoisting ring; connecting plates are arranged at the top; sand core height positioning blocks are connected with the lower sides of the connecting plates through four guide pillars; two bearing pedestals are symmetrically arranged on the outer sides of the bottom wall of the cross beam;tips at the two ends of an overturning driving shaft and an opening-closing shaft are mounted on the inner sides of the bearing pedestals; and the overturning driving shaft is rotatably mounted; two graphite copper bush linear bearings are symmetrically arranged on the two side walls of the cross beam; and the four guide pillars are mounted in the graphite copper bush linear bearings in a sliding manner, so that the guide pillars can be effectively limited to prevent the guide pillars from deflected motion during the up-down moving process so as to avoid damage to the guide pillars.

Description

technical field [0001] The invention relates to the technical field of special casting equipment for commercial vehicles, in particular to a purely pneumatic sand core fully automatic transfer hanger. Background technique [0002] During the production of cylinder block castings in the No. 1 Commercial Vehicle Foundry Factory, the main core group needs to be translated from the transport trolley to the mold of the automatic core setting machine. The previous transfer fixture was replaced. This time, the cylinder sand core (DDI50) needs to be turned over during the transfer process. The transfer fixture cannot use power supply due to site requirements, so a purely pneumatic fixture must be designed and manufactured. to achieve this function. [0003] After patent retrieval, the existing patent No. 201910022733.8 is an invention of an overturning spreader, which is used in the field of casting technology to solve the problem of overturning and dumping of sand cores, sand mold...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a purely pneumatic sand core automatic transfer sling to solve the problem that the structural design proposed in the above background technology is traditionally simple, and it is impossible to turn over the hoisting cylinder core group, and unnecessary shaking is prone to occur during hoisting , the problem of low intelligent operation and relatively cumbersome operation
