Abstract
The invention relates to a press rolling device for tubular workpieces, wherein the device comprises a lathe bed, a lathe spindle and a carriage. A fixed sleeve is fixedly arranged on the lathe spindle, a hydraulic moveable sleeve is coaxially fixedly arranged on the lathe bed between the fixed sleeve and the planker case, a hydraulic sleeve is coaxially sleeved outside the hydraulic moveable sleeve, and the hydraulic sleeve drives the coaxial displacement of the hydraulic moveable sleeve. A rotary sleeve is coaxially arranged on the front end of the hydraulic moveable sleeve. A rolling extruding cutter coaxially operating with the fixed sleeve is arranged in the hydraulic moveable sleeve, the rolling extruding cutter is coaxially fixedly equipped with a push rod coaxially fixedly arranged on a pressure plate, and the pressure plate is fixedly arranged on the planker case. The press rolling device for tubular workpieces is simple in result, scientific and reasonable in design, very compact in entire structure, low in cost, easy to manufacture, capable of being reshaped by using the existing lathe and finishing the extruding, rolling and fine grinding operations on inner holes of the tubular workpieces, good in fine grinding quality and high in degree of finish, so that the device is a more advanced fine grinding device at present.
Description
Technical field
The invention belongs to field of machining, relate to the correct grinding to the tubular workpiece inwall, especially a kind of edging of tubular workpiece is pressed equipment.
Background technology
In machining, the correct grinding of tubular workpiece inwall is cumbersome, and usually technology is: be installed on the lathe tubular workpiece is coaxial, adopt bistrique to carry out inner hole grinding; After having ground one section, tubular workpiece is unloaded, install conversely, remain the grinding of an end again.There is following defective in this technology: 1, twice installing/dismounting makes working (machining) efficiency on the low side; 2, twice installation is difficult to guarantee concentricity; 3, twice grinding is difficult to guarantee the uniformity of grinding accuracy; 4, fineness is relatively poor, and grinding is inhomogeneous.
Through retrieval, do not find identical with present patent application or akin publication document.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, provide the edging of a kind of simple in structure, design science, edging combines, grinding accuracy is high tubular workpiece to press equipment.
The objective of the invention is to realize like this:
A kind of edging of tubular workpiece is pressed equipment; Comprise the body of lathe bed, lathe spindle, carriage box; Side at the body of lathe bed installs lathe spindle, on the guide rail of the body of lathe bed, moves carriage box, and this carriage box is through lead screw transmission mode left and right displacement on the guide rail of the body of lathe bed; It is characterized in that: on lathe spindle, install a fixed cover; The coaxial hydraulic pressure movable sleeve that installs on the body of lathe bed between fixed cover and the carriage box, this hydraulic pressure movable sleeve has a hydraulic sleeve with outer shaft sleeve, and hydraulic sleeve promotes the same axial displacement of hydraulic pressure movable sleeve; At coaxial installation one pivoted housing of hydraulic pressure movable sleeve front end; In the hydraulic pressure movable sleeve, with the coaxial operation of fixed cover one edging cutter is installed, this edging cutter is coaxial to install with push rod, on the pressing plate that this push rod is coaxial to be packed on the carriage box to be installed.
And the head of said edging cutter is installed a blunt knife, and radial equipartition is equipped with roller bearing on the edging cutter at blunt knife rear portion.
And, between hydraulic sleeve and hydraulic pressure movable sleeve, being shaped on admission chamber respectively and going out sap cavity, admission chamber connects the feed tube of being installed on the hydraulic sleeve, goes out sap cavity and connects the drain pipe of being installed on the hydraulic sleeve.
Advantage of the present invention and good effect are:
1, this device adopts the hydraulic pressure locate mode, and between the coaxial fixed cover and hydraulic pressure movable sleeve that is packed in machine tool chief axis of tubular workpiece, accurate positioning is reliable.
2, this device installs push rod on the carriage box of lathe; At the coaxial edging cutter that installs of the head of push rod, this edging cutter is coaxial to be installed in the hydraulic pressure movable sleeve, and the power of carriage box capable of using is with the coaxial jacking of edging cutter; Though and the tubular workpiece machine tool chief axis rotates; The edging cutter is made up of the roller bearing of blunt knife and radial equipartition, can realize the crowded correct grinding that rolls to tubular workpiece, owing to adopted the extruding of blunt knife and the dual processing of roll extrusion of roller bearing; Make the inwall of tubular workpiece highly polished, high conformity, effectively improved the quality of correct grinding.
3, result of the present invention is simple, and design science is reasonable, and total is very compact; With low cost, easy to manufacture, existing lathe repacking capable of using gets final product; Endoporus that can disposable completion tubular workpiece squeezes and rolls correct grinding, and the correct grinding quality is good, highly polished, is comparatively advanced at present correct grinding equipment.

The specific embodiment
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative,
Not determinate, can not limit protection scope of the present invention with this.
A kind of edging of tubular workpiece is pressed equipment; Comprise the body of lathe bed 13, lathe spindle 1, carriage box 11; Side at the body of lathe bed installs lathe spindle, on the guide rail of the body of lathe bed, moves carriage box, and this carriage box is through leading screw 3 kinds of drive left and right displacement on the guide rail of the body of lathe bed.
Innovative point of the present invention is:
On lathe spindle, install a fixed cover 2; The coaxial hydraulic pressure movable sleeve 6 that installs on the body of lathe bed between fixed cover and the carriage box, this hydraulic pressure movable sleeve has a hydraulic sleeve 8 with outer shaft sleeve, promptly is positioned at coaxial installation one pivoted housing 5 of fixed cover direction at hydraulic pressure movable sleeve front end; Coaxial top tubulature shape workpiece 14 between this pivoted housing and the fixed cover; Between hydraulic sleeve and hydraulic pressure movable sleeve, be shaped on admission chamber 16 respectively and go out sap cavity 15, admission chamber connects the feed tube of being installed on the hydraulic sleeve 9, goes out sap cavity and connects the drain pipe of being installed on the hydraulic sleeve 7; Through the turnover of hydraulic pump control oil, promote hydraulic pressure thus and be actively set on the coaxial turnover displacement in the hydraulic sleeve; In the hydraulic pressure movable sleeve, with the coaxial operation of fixed cover one edging cutter 4 is installed, this edging cutter is coaxial to install with push rod 12, on the pressing plate 10 that this push rod is coaxial to be packed on the carriage box to be installed.
The head of said edging cutter is installed a blunt knife 17, and radial equipartition is equipped with roller bearing 18 on the edging cutter at blunt knife rear portion.
Operation principle of the present invention is:
Between the coaxial fixed cover and hydraulic pressure movable sleeve that is packed in machine tool chief axis of tubular workpiece, air-driven hydraulic pump installs the tubular workpiece location, starts machine tool chief axis, and tubular workpiece rotates; Promote the carriage box of lathe; The push rod that installs on it promotes in the endoporus of edging cutter entering tubular workpiece; Power through carriage box is with the coaxial jacking of edging cutter; Though and tubular workpiece machine tool chief axis rotation, the edging cutter is made up of the roller bearing of blunt knife and radial equipartition, has adopted extruding and the roller bearing of the blunt knife crowded correct grinding that rolls to tubular workpiece.
