Description
Technical field
Machining equipment technical field of the present invention, is specifically related to a kind of positioning tool for using during milling back fork lower planes.
Background technology
The gear shift fork that reverses gear is one of vitals of automotive transmission, for being cast as shaped piece, need to carry out fine finishining with milling machine to the lower planes of shift fork, in existing process, the circular shaft position of back fork clamps by usual employing scroll chuck, then adopts horizontal milling machine to process.Because the lower planes of back fork all will carry out Milling Machining, need to carry out twice clamping contraposition, bother very much, cause part processing precision low, and production efficiency is low.
Summary of the invention
For above-mentioned technical problem, plan provides a kind of milling back fork biplanar auxiliary locating tool equipment, when carrying out fine finishining with milling machine to the lower planes of shift fork, by this positioning tool, clamping workpiece is located, convenient and swift and once can process two workpiece simultaneously, enhance productivity and machining accuracy.
For this reason, the technical solution adopted in the present invention is: the biplanar auxiliary locating tool equipment of a kind of milling back fork, comprise stand (1) and tool base plate (2), it is characterized in that: described tool base plate (2) is positioned at directly over stand (1), 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), between described tool base plate (2) and stand (1), left and right is arranged at intervals with left vertically cylinder (9) and the vertical cylinder in the right side (10), the upper left side of described tool base plate (2) is installed with left riser (4), the upper right side of tool base plate (2) is installed with right riser (5), and it is left, right riser (4, 5) all near the leading edge of tool base plate (2),
The rear wall of described right riser (5) is installed with the right suit cylinder (6) perpendicular to rear wall, mate with back fork prong width and the right locating piece (7) in back fork prong can be stretched into, vertical cylinder (8) in the top of tool base plate (2) is provided with, when the circle hole sleeve of back fork is on right suit cylinder (6), when right locating piece (7) stretches in the prong of back fork simultaneously, in the push rod of vertical cylinder (8) protrude upward after be just in time bearing in the lower surface of back fork, the waist of back fork is just in time bearing in after the push rod of right vertically cylinder (10) protrudes upward, the push rod of vertical cylinder (8) in described, right suit cylinder (6), the push rod of right vertically cylinder (10), right locating piece (7) from left to right sets gradually,
The rear wall of described left riser (4) is installed with the left suit cylinder (11) perpendicular to rear wall, mate with back fork prong width and the left locating piece (12) in back fork prong can be stretched into, for supporting the left rest pad (13) of back fork upper surface, after back fork is rotated counterclockwise 180 °, and by the circle hole sleeve of back fork on left suit cylinder (11), left locating piece (12) stretches in the prong of back fork simultaneously, when left rest pad (13) 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 left vertically cylinder (9) protrudes upward, and left locating piece (12), the push rod of left vertically cylinder (9), left suit cylinder (11), left rest pad (13) from left to right sets gradually.
Using method: first place workpiece to be processed, by the circle hole sleeve of one of them back fork on right suit cylinder, and make right locating piece snap in the prong of back fork, after another back fork (the back fork of the good upper surface of milling) being rotated counterclockwise 180 ° simultaneously, again by the circle hole sleeve of this back fork on left suit cylinder, and make left locating piece snap in the prong of this back fork, (because the back fork in left side processes upper surface below the upper surface that left rest pad is bearing in back fork, therefore left rest pad can directly be used, and the lower surface of right side back fork is matsurface, vertical cylinder in increase by is also needed to use as rest pad), afterwards, vertical cylinder, left vertically cylinder and the vertical cylinder in the right side in restarting, the lower surface of right side back fork is just in time bearing in after the push rod of vertically cylinder is protruded upward, the waist of right side back fork is just in time bearing in after the push rod of right vertically cylinder protrudes upward, just in time be bearing in the waist of left side back fork after the push rod of left vertically cylinder protrudes upward, now Set and Positioning completes, because two back fork opposition are arranged, the facing cutter of vertical knee-type milling machine, just in time between two back forks, processes at one time the right side upper plane of back fork, the lower plane of left side back fork by facing cutter.After machining, in the push rod of vertically cylinder, left vertically cylinder and the vertical cylinder in the right side retract, the back fork in left side is taken off, right side back fork be rotated counterclockwise 180 ° after, the clamping position putting into left side proceeds the processing of lower plane, then a clamping position new workpiece being put into right side carries out the processing of upper plane.
Preferred as such scheme, the described right side, left locating piece (7,12) are by the localization part stretched in back fork prong, the mounting portion one composition 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, mounting portion its localization part downward bending relatively of described right locating piece (7).Set up installation position for fixing with each self-corresponding riser, the prong matched in clearance of localization part and back fork is with conveniently assemble and disassemble workpiece, mounting portion its localization part downward bending relative of right locating piece takes up room to reduce, thus reduces the height of right riser.
Further, the push rod termination of the vertical cylinder in a described left side (9), right vertically cylinder (10) 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, design ingenious, by this positioning tool, clamping workpiece is located, with vertical knee-type milling machine, fine finishining is carried out to the lower planes of shift fork again, the lower plane of the upper plane and another workpiece that once can complete a workpiece is processed, convenient mounting and clamping is quick, substantially increases production efficiency and machining accuracy.
