Cast clamping mechanism of vibrating core remover

Abstract

The invention relates to a cast clamping mechanism of a vibrating core remover. The cast clamping mechanism comprises a vibrating core remover (1), wherein a cast clamp mechanism (3) is mounted at the middle part of the vibrating core remover (1) and can separately clamp two identical casts. Air hammers (2) are mounted at symmetrical two side areas of the cast clamp mechanism (3), areas between the air hammers (2) and the cast clamp mechanism (3) are cast placing positions (5), air bags (4) are separately arranged at the two sides, corresponding to the air hammers (2), of the cast clamp mechanism (3), and the casts are clamped or unclamped through inflating or deflating the air bags. According to the cast clamping mechanism of the vibrating core remover, the disadvantage of rigid clamping is overcome by a flexible clamping method, part of a hammering force can be buffered, and the damage to the casts is avoided; in addition, the size of a clamping force can be adjusted in accordance with that the size of the clamping force is slightly greater than that of the hammering force, and the time tact and reliability of clamping are in line with the requirements of a whole automated production line.

Description

technical field [0001] The invention relates to a cleaning of non-ferrous metal castings, in particular to a clamping mechanism for castings of a vibration core machine. Background technique [0002] When using the vibration method to clean the sand core in the inner cavity of non-ferrous metal castings, how the castings are clamped on the vibrating core machine is very important. If the casting is too tight, the casting will be damaged. If the casting is too loose, it will fall off when it is hammered. When it is rigidly clamped, the casting will be hammered. It will shatter when hit, so special clamping methods must be adopted. In addition, in the automatic batch production, the time beat of the vibration core must meet the needs of the entire production line, so there are also requirements for the time and reliability of the clamping, which are difficult to meet with the general clamping method. Contents of the invention [0003] The purpose of the present invention is...

When it is rigidly clamped, the casting will be hammered will shatter when hit, so special clamping is necessary

In addition, in the automatic batch production, the time beat of the vibration core must meet the needs of the entire production line, so the requirements for the time and reliability of the clamping are also put forward, and the general clamping method is difficult to meet
