Problems solved by technology

The traditional processing method needs to manually check whether the parts are installed in the correct position one by one. The fixtures used in this method often cannot realize or partially realize the angular direction, end face and center positioning of the parts to be processed, and manually detect the position of the parts to be processed. Fixed position
Therefore, the processing efficiency is relatively low; the accuracy of the clamping position is not enough; the processing cost is also high

Abstract

The invention discloses a fixture suitable for flange part machining. The fixture comprises a chuck oil cylinder and a supporting piece. The chunk oil cylinder is an oil cylinder in a straight cylinder shape. The supporting piece is fixed to the upper end face of the chuck oil cylinder. A floating positioning block is fixed on the supporting piece. An elastic angular orientation positioning block is arranged on the side face of the supporting piece. The center position of the chuck oil cylinder is connected with a pulling rod in the vertical direction. The pulling rod is sleeved with a tensioning core shaft. The tensioning core shaft is sleeved with a spline tensioning sleeve. The spline tensioning sleeve is sleeved with a flange part to be machined. One end, far from the chuck oil cylinder, of the tensioning core shaft is sleeved with a tensioning block. The fixture has the beneficial effects that mounting and clamping are convenient, the structure is simple, the fixture is suitable for part machining in batches, the machine efficiency is high, and the cost is low.

Description

[0001] Technical field: [0002] The invention relates to a fixture, in particular to a fixture suitable for processing flange parts. [0003] Background technique: [0004] The flange parts are odd-shaped parts, and the fixing of the parts is an indispensable and important link in the manufacturing process. At present, the clamping and fixing method of flange parts mainly uses traditional clamping tools combined with manual operations. [0005] To complete the batch processing of flange parts on a vertical machining center, the success of the fixture is crucial. The traditional processing method requires manual inspection of the installation position of the parts one by one. The fixtures used in this method often cannot realize or partially realize the angular, end and center positioning of the parts to be processed, and manual inspection of the parts to be processed is required. Fixed position. Therefore, the processing efficiency is relatively low; the accuracy of the card mounti...
