The rear wall of described riser (4) is installed with the suit cylinder (6) perpendicular to rear wall, mate with back fork prong width and the locating piece (7) in back fork prong can be stretched into, for supporting the rest pad (8) of back fork upper surface, after back fork is rotated counterclockwise 180 °, and by the circle hole sleeve of back fork on suit cylinder (6), locating piece (7) stretches in the prong of back fork simultaneously, when rest pad (8) is bearing in below the upper surface of back fork, the waist of back fork is just in time bearing in after the push rod of vertical cylinder (5) protrudes upward, and locating piece (7), the push rod of vertical cylinder (5), suit cylinder (6), rest pad (8) from left to right sets gradually.
Using method: first place workpiece to be processed, after back fork (the back fork of the good upper surface of milling) is rotated counterclockwise 180 °, again the circle hole sleeve of this back fork is being set with on cylinder, and in the prong making locating piece snap in this back fork, rest pad be bearing in back fork upper surface below (because this back fork processes upper surface, therefore can directly use rest pad to be used for supporting smooth upper surface); Afterwards, restart vertical cylinder, be just in time bearing in the waist of back fork after the push rod of vertical cylinder is protruded upward, now Set and Positioning completes; The facing cutter of vertical knee-type milling machine is to lower feeding, thus the lower plane of processing back fork.After machining, vertical cylinder and facing cutter return, then the back fork machined is taken off.
Preferred as such scheme, described locating piece (7) is integrally made up of the localization part stretched in back fork prong, the mounting portion be positioned at outside back fork prong, the prong matched in clearance of localization part and back fork, the width of mounting portion is greater than localization part.Set up installation position for fixing with riser, the prong matched in clearance of localization part and back fork is with conveniently assemble and disassemble workpiece.
Further, the push rod termination of described vertical cylinder (5) is curved surface, and with the SURFACES MATCHING of selector fork supported portion position.Employing curved surface coordinates, and with enlarge active surface, improves supporting dynamics.
Beneficial effect of the present invention: novel, is designed ingenious, is located by clamping workpiece by clamping mechanism, then carries out fine finishining by the upper plane of vertical knee-type milling machine to shift fork, fast very convenient, substantially increases production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of clamping mechanism in the present invention.
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. 2, a kind of process equipment being exclusively used in milling back fork lower plane, primarily of clamping mechanism and vertical knee-type milling machine 10 two parts composition, wherein clamping mechanism is made up of stand 1, tool base plate 2, two-side supporting block 3, riser 4, vertically cylinder 5, suit cylinder 6, locating piece 7, rest pad 8 etc.
Tool base plate 2 is positioned at directly over stand 1, and the middle part of tool base plate 2 is unsettled, two ends, left and right are fixed together by back-up heel 3 and stand 1.Tool base plate 2 adopts middle part unsettled, is in order to vacating space is for arranging vertical cylinder 5.
Between tool base plate 2 and stand 1, be provided with vertical cylinder 5, the top of tool base plate 2 is installed with riser 4 near the position of tool base plate 2 leading edge.The facing cutter of vertical knee-type milling machine 10 is positioned at the right outside side of riser 4.
The rear wall of riser 4 is installed with perpendicular to the suit cylinder 6 of rear wall, mates with back fork prong width and locating piece 7 in back fork prong can be stretched into, for supporting the rest pad 8 of back fork upper surface.After back fork is rotated counterclockwise 180 °, and by the circle hole sleeve of back fork on suit cylinder 6, simultaneously locating piece 7 stretches in the prong of back fork, rest pad 8 is when being bearing in below the upper surface of back fork, the waist of back fork is just in time bearing in after the push rod of vertical cylinder 5 protrudes upward, and the push rod of locating piece 7, vertically cylinder 5, suit cylinder 6, rest pad 8 from left to right set gradually, thus ensure that back fork on riser during clamping, lower plane be positioned at right side and upward, and prong be positioned at left side.
Preferably, locating piece 7 is by the localization part stretched in back fork prong, the mounting portion one composition be positioned at outside back fork prong, and the prong matched in clearance of localization part and back fork, the width of mounting portion is greater than localization part.Meanwhile, the suit diameter of cylinder 6 mates with the Circularhole diameter of back fork, both matched in clearance, convenient mounting or dismounting.
In addition, the push rod termination of vertical cylinder 5 is curved surface, and with the SURFACES MATCHING of selector fork supported portion position.
Before processing, first back fork 9 to be processed is placed, after the back fork 9 of the good upper surface of milling is rotated counterclockwise 180 °, again the circle hole sleeve of this back fork 9 is being set with on cylinder 6, and in the prong making locating piece 7 snap in this back fork 9, rest pad 8 is bearing in below the upper surface of this back fork 9, because the upper surface of back fork 9 processes, therefore can rest pad be directly used to support; Afterwards, restart vertical cylinder 5, be just in time bearing in the waist of back fork 9 after the push rod of left vertically cylinder 5 is protruded upward, now Set and Positioning completes; The facing cutter of vertical knee-type milling machine 10 is to lower feeding, thus the upper plane of processing back fork 9.After machining, vertical cylinder 5 and facing cutter return, then the back fork 9 machined is taken off.
