Abstract
The invention discloses a rapid clamping mechanism for bearing block end face machining. A first pressing plate, a second pressing plate, a third pressing plate, an end face supporting pin and a horizontal supporting block are arranged on the front wall of an L-shaped angle iron plate. The first pressing plate and the horizontal supporting block are arranged at the lower left corner of the L-shaped angle iron plate. The second pressing plate and the end face supporting pin are arranged at the lower right corner of the L-shaped angle iron plate. The third pressing plate is arranged over the part between the first pressing plate and the second pressing plate. A sliding positioning pin is inserted in a strip-shaped groove of the horizontal supporting block and used for being inserted in a circular hole correspondingly formed in a workpiece. Each pressing plate is provided with a bolt and a nut for pressing the workpiece. A movable strut with the axis extending front and back is arranged between each pressing plate and the front wall of the L-shaped angle iron plate. The horizontal supporting block is fixed to the L-shaped angle iron plate through one screw and two positioning pins. By means of axial press fitting, machining of two end faces is finished at a time, the clamping frequency is reduced, the component precision is guaranteed, and the production efficiency is improved.

Technical field
The present invention relates to technical field of tooling clamps, especially for the clamping mechanism 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.
Summary of the invention
The present invention aims to provide a kind of clamping mechanism 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 solution adopted in the present invention is: a kind of bearing block end face processing quick clamping mechanism, 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, 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.
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 ".
Beneficial effect of the present invention: 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 invention.
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 invention will be further described:
Shown in composition graphs 1-Fig. 3, a kind of bearing block end face processing quick clamping mechanism, 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.
First pressing plate 2, horizontal support block 6 are arranged on the lower left corner of L shape angle bar plate 1, and the second pressing plate 3 and end face supporting pin 5 are arranged on the lower right corner of L shape angle bar plate 1, and the 3rd pressing plate 4 is arranged on directly over first, second pressing plate 2,3 between two parties.
First, second, third pressing plate 2,3,4 is equipped with bolt and nut for by Work-sheet pressing respectively.End face supporting pin 5 is horizontally disposed with the end face for holding workpieces 8 lower right corner, and the end face of horizontal support block 6 is used for the end face in the holding workpieces lower left corner.The top of horizontal support block 6 is provided with the bar-shaped trough of front and back extension, and in bar-shaped trough, is fitted with slide jaw 7 in the circular hole inserting corresponding setting on workpiece.Be shelved with the portable stanchion 11 extended before and after axis between the antetheca of each pressing plate and L shape angle bar plate 1, portable stanchion 11 is positioned at the one end away from workpiece, and wherein the front end of the portable stanchion 11 of the second pressing plate 3 correspondence is longer than the front end of end face supporting pin 5.When avoiding the second pressing plate 3 workpiece pressing 8 and the front end of end face supporting pin 5 interfere.Bolt and nut is positioned in the middle part of corresponding pressing plate, one end of pressing plate is pressed on workpiece, the other end of pressing plate is supported by portable stanchion 11, again by nut check, during dismounting workpiece, unscrew nut a little, portable stanchion 11 can be taken off, pressing plate is tilted towards away from one end of workpiece, can workpiece under fast fetching.
