Abstract

The utility model relates to a self-positioning clamping device and belongs to the technical field of cylinder sleeve machining fixtures. The self-positioning clamping device is composed of a fixture shaft, an orientation pin, a tensioning sleeve, a flexible taper sleeve, a taper sleeve orientation pin and a pull rod. The pull rod is installed in a center through hole of the fixture shaft, the tensioning sleeve is installed in the middle of the outer surface of the fixture shaft, the flexible taper sleeve which is installed on the pull rod in a sleeved mode is installed on the right end portion of the fixture shaft, a nut is installed on the pull rod on the outer side of the flexible taper sleeve, and tapers are manufactured at two ends of the inner wall of the tensioning sleeve. By the adoption of the match of the fixture shaft, the tensioning sleeve and the flexible taper sleeve, the cylinder sleeve is enabled to be accurate and high-precision in locating when being processed. A machine tool does not need to be adjusted during each machining process, and therefore clamping time is greatly saved, and production efficiency is improved. The self-positioning clamping device solves the problems that due to the fact that in the prior art, no self-centering device exists, locating speed is low and not accurate, the machine tool needs to be adjusted during each machining process, working efficiency is low, and machining precision is affected. The self-positioning clamping device is convenient to operate, accurate in clamping and locating, and suitable for the clamping of the machining of various types of cylinder sleeves.

Description

A kind of self-align clamping device
Technical field
The utility model relates to a kind of self-align clamping device, belongs to cylinder jacket machining fixture technical field.
Background technology
When the cylinder jacket machined proceeds to fine turning outer circle, finish turning supporting shoulder height degree operation, higher than other operations to the required precision of anchor clamps.But there is following defective in the anchor clamps of existing fine turning outer circle and finish turning supporting shoulder height degree: at first be not have self locating device, add and can only cause locating speed slow by the range estimation location man-hour, locate inaccurate; Next is owing to can not be self-align, causes each processing must adjust lathe, wastes time, and working (machining) efficiency is low, and can not guarantee that allowance is identical, affects process quality.
Summary of the invention
The purpose of this utility model is, provide a kind of and cooperate by clamp shaft, expanding cover and movable tapered sleeve, when realizing the cylinder jacket machined automatically, accurately, quick location, and allowance is even, machining accuracy is high, saves the clamping time, the self-align clamping device of enhancing productivity.
The utility model is to realize by the following technical solutions above-mentioned purpose:
This self-align clamping device is made of clamp shaft, orienting pin, expanding cover, movable tapered sleeve, tapered sleeve orienting pin, nut and pull bar, it is characterized in that: the center of clamp shaft is manufactured with a through hole, pull bar is housed in the through hole, the outer surface middle part of clamp shaft is fixed with an expanding cover by orienting pin, the movable tapered sleeve that is sleeved on the pull bar is equipped with in the right part of clamp shaft, on the pull bar in the movable tapered sleeve outside nut is housed; The inwall two ends of expanding cover are manufactured with tapering, and the tapering of an end cooperates with cone on the clamp shaft, and the tapering of the other end cooperates with the cone of movable tapered sleeve end.
The utility model beneficial effect compared with prior art is:
This self-align clamping device adopts clamp shaft, expanding cover and movable tapered sleeve to cooperate, so that cylinder jacket accurate positioning when machined, speed is fast, and precision is high; The allowance that has guaranteed product is impartial, has improved the stability of product quality; Since configured orienting pin, accurate positioning, and each processing need not to adjust lathe, has greatly saved the clamping time, has improved production efficiency.Locating speed is slow, the location is inaccurate because causing without self locating device to have solved prior art, and the necessary lathe of adjusting of each processing, and work efficiency is low, and allowance is inhomogeneous, affects the problem of machining accuracy.This self-align clamping device is easy to operate, clamps contraposition accurate, and crudy is good, is fit to the mach clamping work of various cylinder jacket.
Description of drawings:
Accompanying drawing is a kind of structural representation of self-align clamping device.
Among the figure: 1, clamp shaft, 2, orienting pin, 3, the expanding cover, 4, movable tapered sleeve, 5, the tapered sleeve orienting pin, 6, nut, 7, pull bar, 8, through hole.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
This self-align clamping device is made of clamp shaft 1, orienting pin 2, expanding cover 3, movable tapered sleeve 4, tapered sleeve orienting pin 5, nut 6 and pull bar 7.The center of clamp shaft 1 is manufactured with a through hole 8, pull bar 7 is housed in the through hole 8, the outer surface middle part of clamp shaft 1 is fixed with expanding cover 3 by orienting pin 2, and the movable tapered sleeve 4 that is sleeved on the pull bar 7 is equipped with in the right part of clamp shaft 1, on the pull bar 7 in movable tapered sleeve 4 outsides nut 6 is housed; The inwall two ends of expanding cover 3 are manufactured with tapering, and the tapering of an end cooperates with cone on the clamp shaft 1, and the tapering of the other end cooperates with the cone of movable tapered sleeve 4 ends.
During this self-align clamping device work, clamp shaft 1 is fixed on the main shaft of lathe, clamping force is provided by the clamping cylinder on its machine tool chief axis, clamping cylinder is by pull bar drive activity tapered sleeve 4 reaches in the through hole 8 at clamp shaft 1 center, by the cone on the movable tapered sleeve 4 and the cone on the clamp shaft 1, force expanding to overlap the inner surface of 3 top tight workpieces and clamping work pieces.And can automatically locate fast and accurately, positioning accuracy is high, and need not to adjust lathe, and is easy to operate, saves the clamping time, improved production efficiency, guaranteed the uniformity of product allowance, improved the stability of product quality.
The above is the specific embodiment of this utility model, above-mentioned not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field can make an amendment or is out of shape the above-mentioned specific embodiment after having read this specification, and does not deviate from essence of the present utility model and scope.
