Description
Technical field
The utility model relates to technical field of tooling clamps, especially for the positioning fixture of fine finishining camshaft bearing bush seat end face.
Background technology
The physical dimension of heavy-duty engine camshaft bearing bush seat is large, by also needing the fine finishining carrying out two end faces after casting.Previous frock add man-hour for by mesoporous to press-fiting, mesopore is easily out of shape, and add man-hour intermediate demand shut down once change press-fit position, production efficiency is low, and twice clamping also can affect the precision of product.
Utility model content
The utility model aims to provide a kind of positioning fixture for the processing of camshaft bearing bush seat end face, can complete the processing of two end faces by clamped one time, production efficiency and product quality high.
For this reason, the technical scheme that the utility model adopts is: a kind of bearing block end face positioning clamp for machining, comprise L shape angle bar plate, the antetheca of L shape angle bar plate is provided with the first pressing plate, second pressing plate, 3rd pressing plate, end face supporting pin and horizontal support block, described first pressing plate, horizontal support block is arranged on the lower left corner of L shape angle bar plate, second pressing plate and end face supporting pin are arranged on the lower right corner of L shape angle bar plate, described 3rd pressing plate is arranged on first between two parties, directly over second pressing plate, first, second, 3rd pressing plate is equipped with bolt and nut for by Work-sheet pressing respectively, described end face supporting pin is horizontally disposed with the end face for the holding workpieces lower right corner, the end face of horizontal support block is used for the end face in the holding workpieces lower left corner, the top of horizontal support block is provided with the bar-shaped trough of front and back extension, and in bar-shaped trough, be fitted with slide jaw in the circular hole inserting corresponding setting on workpiece, the portable stanchion extended before and after axis is shelved with between the antetheca of each pressing plate and L shape angle bar plate, and portable stanchion is positioned at the one end away from workpiece, wherein the front end of the portable stanchion that the second pressing plate is corresponding is longer than the front end of end face supporting pin.
This frock is used for the positioning and clamping that camshaft bearing bush seat end face adds man-hour, first workpiece is placed on the antetheca of L shape angle bar plate, the workpiece lower left corner is supported by horizontal support block, inserted in the circular hole of corresponding setting on workpiece by slide jaw, the workpiece lower right corner is supported by end face supporting pin, last again by first, second, 3rd pressing plate is by Work-sheet pressing, the portable stanchion extended before and after axis is shelved with between the antetheca of each pressing plate and L shape angle bar plate, one end of pressing plate is pressed on workpiece, the other end is supported by portable stanchion, stress balance when ensureing that pressing plate compresses, can better by Work-sheet pressing.This frock carries out installation location by the principle of " two sides one is sold ", and the antetheca of L shape angle bar plate is " simultaneously ", and horizontal support block and end face supporting pin are combined into " simultaneously ", and slide jaw is " pin ".
Preferred as such scheme, horizontal support block is fixed on L shape angle bar plate by a screw and two alignment pins, and two alignment pins are symmetricly set on both sides up and down or the left and right sides of screw; Can reliably fix, again can anti-rotation.
The beneficial effects of the utility model: structure is simple, it is ingenious to design, Set and Positioning is convenient and swift, by axially press-fiting, once completing the processing of two end faces, decreasing clamping times, ensure that the relative accuracy of part, also improve production efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1-Fig. 3, a kind of bearing block end face positioning clamp for machining, forms primarily of L shape angle bar plate 1, first pressing plate 2, second pressing plate 3, the 3rd pressing plate 4, end face supporting pin 5, horizontal support block 6, slide jaw 7, screw 9, alignment pin 10, portable stanchion 11.
L shape angle bar plate 1 preferably adopts L shape angle bar plate to make, and vertical portion is for installing other parts, and the installation that horizontal component is used for self is fixed.The antetheca of L shape angle bar plate 1 is provided with the first pressing plate 2, second pressing plate 3, the 3rd pressing plate 4, end face supporting pin 5 and horizontal support block 6.
