Abstract

The invention relates to a machining fixture for an eccentric part. The machining fixture for the eccentric part comprises a guide rail 1, an upper sliding block 5, a lower sliding block 6, an upper chuck 2, a lower chuck 3 and set screws 7, wherein a dovetail groove 8 is arranged on the guide rail 1, one side of the upper sliding block 5 and one side of the lower sliding block 6 are installed on the dovetail groove 8 on the guide rail, the upper chuck 2 is fixedly installed on the other side of the upper sliding block 5, the lower chuck 3 is fixedly installed on the other side of the lower sliding block 6, one end of the upper chuck 2 and one end of the lower chuck 3 are V-shaped, the two V-shaped end surfaces face to each other, the dimensions of the two V-shaped end surfaces are the same, and two set screws 7 are further arranged on the guide rail 1 and respectively press the upper sliding block 5 and the lower sliding block 6. When the eccentric part is machined, since the machining of the eccentric part is not required to be realized through a center hole of the part, the influences of the center hole and the area of the end surface are avoided, the machining precision is high and the reliability is good.

Description

The clamp for machining of eccentric element
Technical field
The present invention relates to a kind of clamp for machining, especially a kind of clamp for machining of eccentric element.
Background technology
In mechanical field, eccentric shaft is a kind of comparatively common structure, and the feature of this structure is on part, at least to comprise two circular shafts, the axis parallel of these two circular shafts but do not overlap.In the man-hour that adds of like parts, be generally the mode that adopts single shaft processing, be positioned at the machining center hole, position of axis at the two ends of axle, by processing after the top clamping on equipment.This mode need to all arrange centre bore on every axis, and the face area of and axle large for central axis distance enough greatly time, can be realized the object of processing.But for some eccentric shaft part, the distance of axis is very little, even only have several millimeters, in the time that end face arranges centre bore, boring, grinding etc. are very easily affected, two centre bores that arrange like this, intensity, precision and reliability are very poor, and what have even can not realize; Or as some part, eccentric shaft face size is very little, the axle center of a certain section of circular shaft is positioned at outside end face, cannot complete processing by the mode that centre bore is set at end face.
Summary of the invention
The object of this invention is to provide a kind of clamp for machining of eccentric element, avoid adding the impact that is subject to centre bore and face area man-hour, realize the processing of eccentric element, and reach the requirement of machining accuracy and reliability.
Technical scheme of the present invention is, the clamp for machining of eccentric element comprises guide rail, top shoe, sliding block, upper grip, lower chuck, holding screw, on described guide rail, be provided with dovetail groove, the one side of top shoe and sliding block is provided with dovetail structure, and be arranged on the dovetail groove on guide rail, described top shoe and sliding block can slide on guide rail; The another side of top shoe is installed with upper grip, and the another side of sliding block is installed with lower chuck, and described upper grip and one end of lower chuck are V font, and two described V font end faces are relative, measure-alike, and two V font end faces can clamping circular shaft; On described guide rail, be also provided with two holding screws, there is device for screwing up one end of holding screw 7, and the other end withstands on respectively on top shoe and sliding block.Described top shoe is provided with copper sheet with in the plane contacting with holding screw on sliding block.Described top shoe and upper grip, sliding block and lower chuck are fixed by screw, and described device for screwing up is flat recess.
The present invention is by arranging upper grip and the lower chuck that can move respectively along guide shaft, in use, can be by the position of the lower chuck of upper grip, not only can adapt to the clamping requirement of the different diameters of axle, and can be after eccentric part clamping, the axis of clamping position produces certain skew, makes to need the axis of Working position to overlap with process equipment main-shaft axis, realizes the object of processing.Holding screw, after part is installed, carries out the locked of slide block, ensures the reliability of processing.The present invention, in the time of processing eccentric element, does not realize by the centre bore of part, the therefore not impact of acceptor center hole and face area, and machining accuracy is high, good reliability.
