Problems solved by technology

[0004] However, the handle body, the fixed head and the expansion sleeve are fixed by welding, and there must be a weld between the two
On the one hand, the existence of welds affects the appearance of the hydraulic tool holder; on the other hand, the reliability of welding cannot be effectively guaranteed, and there is a possibility of hydraulic oil leakage in the welds
In addition, due to the existence of machining errors, the butt connection between the tool holder body, the fixed head and the expansion sleeve cannot be perfect, and there are more or less tiny dislocations or gaps, which also affect the final forming quality of the hydraulic tool holder

Abstract

A molding process of a slender hydraulic tool handle according to the present invention is characterized in that it includes the following steps: S1: processing and forming the tool handle body, the expansion sleeve and the fixed head respectively; the front end of the tool handle body is processed and formed with a cylindrical extension There is an oil passage in the tool handle body; the fixed head is a cylindrical structure that can be smoothly connected with the extension column; S2: Weld the expansion sleeve and the fixed head on the extension column, and make the tool handle body, expansion sleeve and An oil chamber communicating with the oil passage is formed between the fixed heads; S3: Carry out cutting processing on the outer surfaces of the extension column, the expansion sleeve and the fixed head to form a tapered chuck. It has the advantages of low process difficulty, high molding quality, and the hydraulic tool holder has an integrated appearance.

Description

technical field [0001] The invention relates to the technical field of hydraulic tool holders, in particular to a forming process of hydraulic tool holders. Background technique [0002] Compared with various types of rigid tool holders such as spring sleeve type, shrink-fit type, side-fixed type, and tapered needle roller pressing type, hydraulic tool holders are flexible and fixed, and when the tool holder vibrates, the tool The damage can be greatly reduced, and it has been widely used in modern CNC machining equipment. [0003] Existing slender hydraulic tool handles generally include a tool handle body, an expansion sleeve, a fixed head, a pressure applying component, and an oil seal component. The expansion sleeve is welded and fixed on the conical extension column through the fixed head to form a conical chuck, and an oil cavity is formed between the conical extension column and the expansion sleeve, and an oil passage connecting the oil cavity is also opened in the ...
