Casting inner cavity alignment device

Abstract

The invention provides a casting inner cavity alignment device comprising a first ejection block, a second ejection block, a drive block, a stand column, a positioning sleeve and a regulation part. The first ejection block and the second ejection block are arranged in the two ends of the positioning sleeve correspondingly. An opening is formed in one side of the positioning sleeve. A first throughhole is formed in the other side, opposite to the opening, of the positioning sleeve. A second through hole is formed in the middle of the first ejection block. A third through hole is formed in themiddle of the second ejection block. The two ends of the stand column are inserted in the second through hole and the third through hole correspondingly. A groove is formed in the middle portion of the stand column. A first end of the drive block enters the opening of the positioning sleeve and is connected with the regulation part after passing through the groove and penetrating out from the first through hole of the positioning sleeve. Scale lines are arranged at the position of the end face of a second end of the drive block. By means of movement cooperation between the first ejection block, the second ejection block and the drive block, the reference plane of a casting inner cavity is aligned, the center position or the eccentric position of the casting inner cavity is accurately indicated, and the casting inner cavity alignment device can be suitable for various types of surface quality and can be arranged in the casting inner cavity to be used.

Description

technical field [0001] The invention relates to the technical field of casting alignment, in particular to a casting inner cavity alignment device. Background technique [0002] Casting machining usually needs to process the rough datum plane of the workpiece according to the scribe line, and the scribe line needs to refer to the non-machined plane of the casting itself. This plane is generally determined by multiple reference points. How to align the non-machined casting plane and the number of reference points when aligning How much is the key to the processing quality of casting workpieces. [0003] The non-machined casting plane generally exists in two forms: the outer surface and the inner cavity surface. The outer surface can be aligned by conventional scribing needles and height gauges. For the inner cavity of the casting, especially the inner cavity plane that is often unreachable by the planning needle. Difficult to find. SUMMARY OF THE INVENTION [0004] The in...
