Description
Technical field
The utility model relates to a kind of grip device processing eccentric shaft, and the location particularly for eccentric shaft clamps, as the processing of some multidiameters, little crank throw.
Background technology
Axial workpiece is one of typical part often run in machine.It is mainly used in the driving members such as supporting gear, belt wheel, cam and connecting rod in machinery, with transmitting torque.Because slender axles rigidity is very poor, work in-process is very easily out of shape, and affects very large on machining accuracy and crudy.In working angles, workpiece produces flexural deformation by thermal stretching, and turning is just difficult to carry out, and workpiece can be made time serious to block at top.Workpiece by cutting force, deadweight and rotation time centrifugal force effect, can produce bending, vibration, have a strong impact on its cylindricity and surface roughness.So the jig Design of axial workpiece is extremely important, in order to improve the machining accuracy of eccentric shaft, devise a kind of locating clip clamper for the not processing of axle class on the same line of eccentric shaft and center line.
Existing a kind of fixture processing eccentric shaft, be made up of fixture cover, base plate, installing plate, the first adapter sleeve, the second adapter sleeve, fixed head, inner conical drogue, eccentric cushion block, elastic conical drogue, cover plate and Compress Spring, this fixture can ensure the eccentric throw precision of eccentric shaft, fixture eccentric throw easily easy to adjust, and the mar proof of fixture is improved.
A kind of eccentric shaft processing clamp for lathe, comprise eccentric axle, eccentric mounting and collet, eccentric mounting connected with eccentric axle sliding joining, center line in the center line of its mating holes and eccentric axle is parallel to each other, but not on the same line, eccentric mounting by screw in compression in eccentric axle, eccentric mounting is provided with the mesopore for mounting spring chuck, collet is locked on eccentric mounting by tight loop, changes the collet of different size, can process the eccentric shaft of different size.The utility model has the features such as structure is simple, working (machining) efficiency is high, universal performance is good.
A kind of frock clamp of oblique cambered axle processing, belong to Special tooling clamp, overcome the problems such as the processing cost that existing processing axle head occurs containing the oblique cambered axle of incline structure is high, processing method is loaded down with trivial details, frock clamp of the present utility model, its d-axis and sloping portion are an entirety, its d-axis is stairstepping d-axis, and sloping portion has shoulder hole, and shoulder hole center line is identical with the inclined shaft portion tilting angle being processed oblique cambered axle by it with the angle of d-axis main shaft; Shoulder hole aperture is identical with the last two-stage outside diameter of the straight shaft portions being processed oblique cambered axle by it successively.The utility model structure is simple, easy to manufacture, application the utility model is on engine lathe, just processing tasks can be completed through clamped one time, according to the change requirement of workpiece to be machined medium dip structural point, can the angle of corresponding change fixture, form the seriation of Fixture Design and facilitate the management of frock.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of grip device processing eccentric shaft.
A kind of grip device processing eccentric shaft comprises fixed station, right angle fixed mount, V-type groove, V-type groove piece and holding screw; 4 bolts hole that right angle fixed mount is established by bottom surface are fixed on fixed base, and V-type groove is connected with right angle fixed mount by 2 bolts hole of side, and V-type groove piece is connected with V-type groove by 2 bolts hole, and holding screw is through the screw hole on V-type groove piece.
Described V-type groove offers V-shape breach.
Described holding screw holds out against machining shaft through the screw hole spinning in and out on V-type groove piece.
Leave space along V-type groove vertical direction between described V-type groove and right angle fixed mount, there is no plane-plane contact.
Because slender axles rigidity is very poor, work in-process is very easily out of shape, and affects very large on machining accuracy and crudy.The utility model, as the fixture of processing eccentric shaft, solves in process and locates clamping problems, and the mismachining tolerance that when substantially reducing processing parts, problem of misalignment causes owing to moving, improves production efficiency, reduces processing cost.The utility model fixture is not only with low cost, and processing is simple, and cost is low, and using method is simple, easy to operate, ensure that the crudy of eccentric shaft axle, is also applicable to the processing of some multidiameters, little crank throw in addition.
