Abstract
The invention relates to an axis component process using active center rest that includes center base that has an inner hole, which contains a sleeve. The feature is that: slider hole is set on center base, the direction of center line of slider hole is plumbed to the center line of sleeve; elastic slider that avoids the sleeve swaying is in the slider hole. The elastic slider could be slider connecting to spring, slider with hydraulic pressure or the slider with elasticity itself. The invention could avoid clearance between sleeve and center base and ensure machining accuracy.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of movable center rest in use for machining parts in types of axes.
Background technology
In the machine-building process; run into the processing of axial workpiece through regular meeting; generally process then in the Machining of Shaft-type Parts with the two top axial workpiece two ends centre bores that withstand; wherein on the top dead head that must be contained in the rolling center frame; specifically be with on the top sleeve that is contained in dead head; sleeve slides in the endoporus of dead head; thereby withstand or unclamp workpiece by top; owing to easily rub between sleeve and the dead head inner hole wall; the dead head endoporus is worn and torn; cause that interporal lacuna constantly increases in sleeve and the dead head, and then sleeve will swing in endoporus, influence the machining accuracy of part to be processed.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of simple and reasonable, can avoid sleeve and dead head inner hole wall that friction takes place and produce the movable center rest in use for machining parts in types of axes of wearing and tearing.
Technical scheme of the present invention is as follows:
A kind of movable center rest in use for machining parts in types of axes of the present invention, comprise dead head, dead head has endoporus, sleeve is housed in the endoporus, it is characterized in that: have slider bore on dead head, the direction of slider bore center line is vertical with sleeve centerline, elastic slide block is housed in the slider bore, elastic slide block one end withstands on sleeve on the endoporus one side inwall, and the other end of elastic slide block is supported, and sleeve can not swung.
Elastic slide block of the present invention can be the slide block that is connected with spring, also can be the slide block of band hydraulic pressure, or elastic elastomer block own.
The present invention is owing to be equipped with elastic slide block in the slider bore of dead head, slide block is pressed to sleeve one side inwall of dead head endoporus under external force, like this, sleeve can not swung in the dead head endoporus, sleeve and dead head endoporus just can not produce wearing and tearing, thereby can not cause producing the gap between the two, can not influence the machining accuracy of part to be processed.The present invention is simple and reasonable, can effectively improve the machining accuracy of axial workpiece.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of movable center rest in use for machining parts in types of axes of the present invention, comprise dead head 1, dead head 1 has endoporus 2, and sleeve 3 is housed in the endoporus 2, it is characterized in that: on dead head 1, have slider bore 4, the direction of slider bore 4 center lines is vertical with sleeve 3 center lines, and elastic slide block 5 is housed in the slider bore 4, and elastic slide block 5 one ends withstand on sleeve 3 on the endoporus 2 one side inwalls, the other end of elastic slide block is supported, and sleeve 3 can not swung.
Slider bore 4 of the present invention has a plurality of, and corresponding elastic slide block 5 also has a plurality of, with guarantee sleeve stressed evenly it is parallel that the center line that makes sleeve and inner hole centreline remain, sleeve does not produce skew.
