Sand core overturning clamp

Abstract

The invention relates to the technical field of sand core clamping equipment, and particularly relates to a sand core overturning clamp. The sand core overturning clamp comprises a first clamping arm,a second clamping arm, a first overturning power source, a second overturning power source, a first clamping piece and a second clamping piece, wherein the first overturning power source is installedon the first clamping arm, and the output end of the first overturning power source is in transmission connection with the first clamping piece; and the second overturning power source is installed on the second clamping arm, the output end of the second overturning power source is in transmission connection with the second clamping piece, and the first clamping piece and the second clamping piece are used for clamping the two ends of a sand core correspondingly. According to the sand core overturning clamp, a structure bypassing the periphery of the sand core for avoiding the sand core doesnot exist, and therefore interference is not likely to happen during sand core overturning, and the sand core and the clamping arms are not likely to be damaged.

Description

technical field [0001] The invention relates to the technical field of sand core clamping equipment, in particular to a sand core turning fixture. Background technique [0002] The sand core will use the sand core turning fixture during the transfer process, which generally has two clamping arms, namely the first clamping arm and the second clamping arm, and a synchronization device is set between the two clamping arms. The connection frame, the sand core can be clamped between the active end and the passive end of the synchronous connection frame; the first clamping arm is provided with a turning power source, the active end of the synchronous connection frame is connected to the turning power source, and the synchronous connection The passive end of the frame cooperates with the rotation of the second clamping arm, and the turning power source can drive the synchronous connection frame to turn over, and then the synchronous connection frame can drive the sand core to turn ...

AI Technical Summary

Problems solved by technology

[0003] However, the synchronous connection frame on the existing sand core turning fixture needs to avoid the position of the sand core, so the synchronous connection frame needs to be surrounded by the sand core by the periphery of the sand core. If the structure interferes, once the interference occurs, the synchronous connection frame will exert an unfavorable torque on the sand core and the clamping arm, which will easily cause damage to the sand core and the clamping arm
