Abstract
Provided is a hydraulic controlled self-centering device, comprising a positioning seat, a positioning ring, and an oil cylinder. The positioning ring is installed on the positioning seat. The positioning ring and the positioning seat are in clearance fit. The positioning ring can rotate on the positioning seat. The positioning seat is uniformly provided with a plurality of positioning holes along a peripheral direction. The axial direction of the positioning hole is the radial direction of the positioning seat. The positioning hole is internally provided with a positioning pin. A spring is arranged between the positioning pin and the positioning seat. The corresponding position of each positioning hole is provided with a conical block. The positioning pin contacts the conical surface of the conical block. The conical block is fixedly arranged on the positioning ring. The outer ring of the positioning ring is provided with a gear. The oil cylinder is internally connected with a piston rod. The piston rod in the oil cylinder is connected with a rack. The rack and the gear on the positioning ring are arranged coordinately. Through the oil cylinder, hydraulic clamping and loosening on a device are realized, and operation steps of an operator are reduced, processing auxiliary time is reduced, and labor intensity of workers is reduced.
Description
Technical field
The present invention relates to Machining Technology field, particularly to 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, a crucial positioning datum of polish, and its importance is self-evident.Vertical boring mill is used man-hour to be processed adding, but no matter use gold steel boring or taking uniaxially or biaxially to stand boring all suffers from a cylinder sleeve orientation problem, if it cannot be guaranteed that the dead in line of cylinder sleeve bore axis and boring cutter after cylinder sleeve clamping, or control in a scope the least, after will causing cylinder sleeve right boring, wall thickness is overproof, and interior axially bored line during cylinder sleeve bore axis runout blank, affect cylinder liner blank surplus, more likely cause eccentric wear after cylinder sleeve installation.
Existing right boring positioner majority uses stationary positioned seam mode, and one is the machining accuracy height of requirement positioning spigot frock；Two be the size of the requirement big Excircle machining of preceding working procedure cylinder sleeve and form and position tolerance the highest, if but preceding working procedure does not use numerical control device, then its precision is difficult to reach requirement.Using stationary positioned seam mode to carry out right boring processing, after processing, cylinder sleeve Wall-Thickness Difference is difficult to control in a scope the least；Additionally when frock adjusts if it find that positioning spigot axis runout boring bar axis, the most loaded down with trivial details during adjustment.
Summary of the invention
The technical problem to be solved is to provide a kind of Self-centering device for cylinder sleeve right boring processing, can effectively solve the orientation problem in cylinder sleeve right boring processing, and device is simple and practical, adjusts more convenient.
nullFor solving above-mentioned technical problem，Present invention employs the Self-centering device of a kind of hydraulic control，Including positioning seat、Centring ring and oil cylinder，Described centring ring is arranged on positioning seat，It it is matched in clearance between centring ring and positioning seat，Described centring ring can rotate on positioning seat，Hole, multiple location along the circumferential direction it is evenly arranged with on described positioning seat，The axis direction in hole, described location is positioning seat radial direction，Described location is provided with alignment pin in hole，It is provided with spring between described alignment pin and positioning seat，It is provided with cone block on the correspondence position in each hole, location described，Described alignment pin and the taper-face contact boring block，Described cone block is fixedly mounted on centring ring，It is provided with gear on described centring ring outer ring，Connect in described oil cylinder and have piston rod，Described in-oil cylinder piston rod connects tooth bar，Described tooth bar is equipped with the gear on centring ring.
Further, heretofore described positioning seat is installed with end cap.
The present invention uses alignment pin that cylinder sleeve carries out location clamping, and owing to the movable distance of alignment pin is relatively big, set of device can meet the process requirements of various model cylinder sleeve, decreases the time that frock is changed, adjusted；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；Realize the hydraulic clamp to device by oil cylinder and unclamp, decreasing the operating procedure of operator, decreasing and process non-cutting time, alleviate the labor intensity of workman.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
nullWith reference to Fig. 1，For the Self-centering device processed for cylinder sleeve，Including positioning seat 1 and centring ring 2，Described centring ring 2 is arranged on positioning seat 1，It it is matched in clearance between centring ring 2 and positioning seat 1，Described centring ring 2 can rotate on positioning seat 1，Hole, multiple location 8 along the circumferential direction it is evenly arranged with on described positioning seat 1，The axis direction in hole, described location 8 is positioning seat 1 radial direction，It is provided with alignment pin 5 in hole, described location 8，It is provided with spring 6 between described alignment pin 5 and positioning seat 1，It is provided with cone block 4 on the correspondence position in each hole 8, location described，Described alignment pin 5 and the taper-face contact boring block 4，Described cone block 4 is fixedly mounted on centring ring 2，It is provided with gear 7 on described centring ring 2 outer ring，Connect in described oil cylinder 10 and have piston rod 11，Described piston rod 11 connects tooth bar 9，Described tooth bar 9 is equipped with the gear 7 on centring ring 2.
First positioning seat 1 is installed, adjusts axiality and the perpendicularity of seam and boring bar on positioning seat 1, meet after requiring, use bolt fastening 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 can lay cone block 4 at three, arrange the hole, location 8 that can lay alignment pin 5, spring 6 at decile processes on positioning seat 1 three.Can be rotated by band mantle block 4 by centring ring 2, cone block 4 promotes alignment pin 5 to advance when rotating, and at three, alignment pin 5 clamps the big excircle orientation of cylinder sleeve, can process after upper platen clamping cylinder sleeve.
After cylinder sleeve machines, rotating centring ring 2 counterclockwise, the elastic force by spring 6 ejects alignment pin 5, thus unclamps cylinder sleeve, finally takes out cylinder sleeve.
Centring ring 2 Excircle machining is become gear shape, and with the tooth bar 9 on piston rod 11 with the use of；Piston rod 11 and tooth bar 9 is driven to move forward and backward by mobile before and after piston 12 in oil cylinder 10, tooth bar 9 drives centring ring 2 to rotate clamping, unclamp cylinder sleeve by the gear 7 on centring ring 2, thus the hydraulic control that device clamping can be realized, unclamp, facilitate the processing of operator.
Described end cap 3 is fixedly mounted on positioning seat 1 by screw, can effectively prevent the iron filings produced in the course of processing from entering the gap between centring ring 2 and positioning seat 1, and cause device to occur grinding, pulling phenomenon.
