Description
Technical field
The utility model relates to Machining Technology field, particularly a kind of Self-centering device for cylinder sleeve right boring processing.
Background technology
The right boring processing of cylinder jacket is requisite operation in current cylinder sleeve machining process, and the cylinder sleeve bore after right boring is as postorder semifinishing, an accurately machined crucial positioning datum, and its importance is self-evident.Vertical boring mill is adopted man-hour to process adding, but adopt golden steel boring or take single shaft or twin shaft to stand boring and be all faced with a cylinder sleeve orientation problem, the dead in line of cylinder sleeve bore axis and boring cutter after if cylinder sleeve clamping can not be ensured, or control in a very little scope, after cylinder sleeve right boring is caused in capital, wall thickness is overproof, and interior axially bored line during cylinder sleeve bore axis runout blank, affect cylinder liner blank surplus, eccentric wear after more likely causing cylinder sleeve to install.
Existing right boring positioner majority adopts stationary positioned seam mode, and one is that the machining accuracy of requirement positioning spigot frock is high; Two is that the size of the large Excircle machining of requirement preceding working procedure cylinder sleeve and form and position tolerance are all higher, if but preceding working procedure does not use numerical control device, then and its precision not easily reaches requirement.Use stationary positioned seam mode to carry out right boring processing, after processing, cylinder sleeve Wall-Thickness Difference is difficult to control in a very little scope; If find positioning spigot axis runout boring bar axis in addition when frock adjusts, very loaded down with trivial details during adjustment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Self-centering device for cylinder sleeve right boring processing, and effectively can solve the orientation problem in cylinder sleeve right boring processing, device is simple and practical, adjusts more convenient.
For solving the problems of the technologies described above, the utility model have employed a kind of Self-centering device for cylinder sleeve processing, comprise positioning seat and centring ring, described centring ring is arranged on positioning seat, it is matched in clearance between centring ring and positioning seat, described centring ring can rotate on positioning seat, described positioning seat is along the circumferential direction evenly provided with multiple locating hole, the axis direction of described locating hole is that positioning seat is radial, alignment pin is provided with in described locating hole, spring is provided with between described alignment pin and positioning seat, the correspondence position of each locating hole described is provided with cone block, described alignment pin and the taper-face contact of boring block, described cone block is fixedly mounted on centring ring, described centring ring is installed with handle.
Further, positioning seat described in the utility model is installed with end cap.
The utility model adopts alignment pin to position clamping to cylinder sleeve, and because the movable distance of alignment pin is comparatively large, set of device can meet the process requirements of various model cylinder sleeve, decreases the time of frock replacing, adjustment; Due to the reduction of bore hole Wall-Thickness Difference, the allowance of cylinder liner blank can be reduced, reduce cylinder liner blank casting cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, positioning seat; 2, centring ring; 3, end cap; 4, block is bored; 5, alignment pin; 6, spring; 7, handle; 8, locating hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1, for the Self-centering device processed for cylinder sleeve, comprise positioning seat 1 and centring ring 2, described centring ring 2 is arranged on positioning seat 1, it is matched in clearance between centring ring 2 and positioning seat 1, described centring ring 2 can rotate on positioning seat 1, described positioning seat 1 is along the circumferential direction evenly provided with multiple locating hole 8, the axis direction of described locating hole 8 is that positioning seat 1 is radial, alignment pin 5 is provided with in described locating hole 8, spring 6 is provided with between described alignment pin 5 and positioning seat 1, the correspondence position of each locating hole 8 described is provided with cone block 4, described alignment pin 5 and the taper-face contact of boring block 4, described cone block 4 is fixedly mounted on centring ring 2, described centring ring 2 is installed with handle 7.
First positioning seat 1 is installed, adjusts axiality and the perpendicularity of seam and boring bar on positioning seat 1, after meeting the demands, use bolted positioning seat 1.Centring ring 2 and positioning seat 1 are matched in clearance, and can rotate on positioning seat 1, and on centring ring 2, decile processes the groove that cone block 4 can be laid by three places, and three places that decile processes on positioning seat 1 arrange the locating hole 8 can laying alignment pin 5, spring 6.Mantle block 4 can be with to rotate by centring ring 2, promote alignment pin 5 when cone block 4 rotates and advance, three place's alignment pins 5 clamp the large excircle orientation of cylinder sleeve, can process after upper platen clamping cylinder sleeve.
After cylinder sleeve machines, be rotated counterclockwise centring ring 2, the elastic force by spring 6 ejects alignment pin 5, thus unclamps cylinder sleeve, finally takes out cylinder sleeve.
Described end cap 3 is fixedly mounted on positioning seat 1 by screw, effectively can prevent the iron filings produced in process from entering gap between centring ring 2 and positioning seat 1, and cause device to occur grinding, pull phenomenon.
Claims (2)
1. for the Self-centering device of cylinder sleeve processing, it is characterized in that: comprise positioning seat and centring ring, described centring ring is arranged on positioning seat, it is matched in clearance between centring ring and positioning seat, described centring ring can rotate on positioning seat, described positioning seat is along the circumferential direction evenly provided with multiple locating hole, the axis direction of described locating hole is that positioning seat is radial, alignment pin is provided with in described locating hole, spring is provided with between described alignment pin and positioning seat, the correspondence position of each locating hole described is provided with cone block, described alignment pin and the taper-face contact of boring block, described cone block is fixedly mounted on centring ring, described centring ring is installed with handle.
