Description
Technical field
This utility model relates to rocking arm nuts Inner arc Vehicle Processing technology, is related specifically to a kind of rocking arm nuts Inner arc workpiece machining clamp.
Background technology
The global shape of rocking arm nuts is rectangular body, and both sides, outside have a chamfering respectively, and both sides, inner side have a platform respectively, and middle inside has a circular arc, for coordinating with other parts.Generally use forging mode to process rocking arm nuts blank, then, carry out machining.Further, Vehicle Processing mode is used to process the circular arc of middle inside.On the basis of prior art rocking arm nuts Inner arc Vehicle Processing method of clamping uses two sides, use pressing plate to be fixed on connection dish by rocking arm nuts blank and machine.Owing to the shape and size of two sides are not the most regular, it is difficult to ensure that the axis of blank Inner arc overlaps with shaft axis (i.e. so-called " centering " is inaccurate) behind location, add employing pressing plate and fix, have impact on the efficiency of loading and unloading.Obviously, prior art rocking arm nuts Inner arc Vehicle Processing method of clamping also exists that centering is inaccurate and the problem such as the efficiency of loading and unloading is relatively low.
Summary of the invention
For the problems such as centering is inaccurate and the efficiency of loading and unloading is relatively low solving that prior art rocking arm nuts Inner arc Vehicle Processing method of clamping exists, the utility model proposes a kind of rocking arm nuts Inner arc workpiece machining clamp.This utility model rocking arm nuts Inner arc workpiece machining clamp, including clutch disk and clamping device；Described clutch disk is provided centrally with feed hole, and two clamping devices are symmetricly set on upper and lower both sides, feed hole；Described clamping device includes locating piece, base plate, upper cover plate, lamina tecti, slide block and fastening bolt；Described locating piece is rectangle, and wherein two corner is provided with rectangular indentation；Two locating pieces are symmetricly set on the left and right sides, feed hole and are oppositely arranged with rectangular indentation, and, the distance that breach is relative is identical with the width of rocking arm nuts；Described base plate, upper cover plate and lamina tecti constitute slideway；Described slide block is arranged in slideway, and the front end of slide block be provided with rocking arm nuts outside the V-arrangement opening that matches of both sides chamfering；Described fastening bolt is connected through lamina tecti with slide block rear end.
The Advantageous Effects of this utility model rocking arm nuts Inner arc workpiece machining clamp is to use V-arrangement opening to promote both sides chamfering outside rocking arm nuts to realize location, has preferable centring property；Further, easy to loading and unloading, simple in construction.

With specific embodiment, utility model rocking arm nuts Inner arc workpiece machining clamp is further described below in conjunction with the accompanying drawings.
Detailed description of the invention
Accompanying drawing 1 is the schematic three dimensional views of rocking arm nuts, and as seen from the figure, the global shape of rocking arm nuts is rectangular body, and both sides, outside have a chamfering respectively, and both sides, inner side have a platform respectively, and middle inside has a circular arc, for coordinating with other parts.Generally use forging mode to process rocking arm nuts blank, then, carry out machining.Further, Vehicle Processing mode is used to process the circular arc of middle inside.On the basis of prior art rocking arm nuts Inner arc Vehicle Processing method of clamping uses two sides, use pressing plate to be fixed on connection dish by rocking arm nuts blank and machine.Owing to the shape and size of two sides are not the most regular, it is difficult to ensure that the axis of blank Inner arc overlaps with shaft axis (i.e. so-called " centering " is inaccurate) behind location, add employing pressing plate and fix, have impact on the efficiency of loading and unloading.Obviously, prior art rocking arm nuts Inner arc Vehicle Processing method of clamping also exists that centering is inaccurate and the problem such as the efficiency of loading and unloading is relatively low.
Accompanying drawing 2 is the front elevational schematic of utility model rocking arm nuts Inner arc workpiece machining clamp, accompanying drawing 3 is the diagrammatic side-view cross-sectional schematic diagram of utility model rocking arm nuts Inner arc workpiece machining clamp, in figure, 1 is clutch disk, and 2 is locating piece, and 3 is upper cover plate, 4 is lamina tecti, 5 is fastening bolt, and 6 is base plate, and 7 is slide block.As seen from the figure, this utility model rocking arm nuts Inner arc workpiece machining clamp, including clutch disk 1 and clamping device；Described clutch disk is provided centrally with feed hole, and two clamping devices are symmetricly set on upper and lower both sides, feed hole；Described clamping device includes locating piece 2, base plate 6, upper cover plate 3, lamina tecti 4, slide block 7 and fastening bolt 5；Described locating piece 2 is rectangle, and wherein two corner is provided with rectangular indentation；Two locating pieces 2 are symmetricly set on feed hole arranged on left and right sides and are oppositely arranged with rectangular indentation, and, the distance that breach is relative is identical with the width of rocking arm nuts；Described base plate 6, upper cover plate 3 and lamina tecti 4 constitute slideway；Described slide block 7 is arranged in slideway, and the front end of slide block 7 be provided with rocking arm nuts outside the V-arrangement opening that matches of both sides chamfering；Described fastening bolt 5 is connected through lamina tecti with slide block 7 rear end.Time specifically used, by rocking arm nuts blank to be processed from side, feed hole be placed on locating piece rectangular indentation relatively from, the distance relative due to breach is identical with the width of rocking arm nuts; inside rocking arm nuts blank, two corners are just stuck in rectangular indentation; screw fastening bolt; rocking arm nuts blank under the promotion of slide block to locating piece one side shifting; due to the front end of slide block be provided with rocking arm nuts outside the V-arrangement opening that matches of both sides chamfering; arm bolt hat felt part centering as far as possible will be promoted, there is preferable centring property.After completion of processing, unscrewing fastening bolt can take off the promotion arm bolt cap processed, and loads and unloads more convenient.
Obviously, the Advantageous Effects of this utility model rocking arm nuts Inner arc workpiece machining clamp is to use V-arrangement opening to promote both sides chamfering outside rocking arm nuts to realize location, has preferable centring property；Further, easy to loading and unloading, simple in construction.
