Technical field
Machining equipment technical field of the present invention, is specifically related to a kind of clamping mechanism used during plane on milling back fork.
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, in existing process by the upper plane of milling machine to shift fork, the circular shaft position of back fork clamps by usual employing scroll chuck, then adopts horizontal milling machine to process.Utilize scroll chuck to carry out clamping, bother very much, production efficiency is low.
Summary of the invention
For above-mentioned technical problem, intending the quick clamping mechanism that plane on a kind of milling back fork is provided, when carrying out fine finishining by the upper plane of milling machine to shift fork, by this clamping mechanism, clamping workpiece being located, fast very convenient, to enhance productivity.
For this reason, the technical solution adopted in the present invention is: the quick clamping mechanism of plane on 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), the first vertical cylinder (4) between described tool base plate (2) and stand (1), the top of described tool base plate (2) is installed with riser (5) near the position of tool base plate (2) leading edge,
The rear wall of described riser (5) 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, second vertical cylinder (8) is installed in the top of tool base plate (2), when the circle hole sleeve of back fork is on suit cylinder (6), when locating piece (7) stretches in the prong of back fork simultaneously, the lower surface of back fork is just in time bearing in after the push rod of the second vertical cylinder (8) protrudes upward, the waist of back fork is just in time bearing in after the push rod of the first vertical cylinder (4) protrudes upward, the push rod of the described second vertical cylinder (8), suit cylinder (6), the push rod of the first vertical cylinder (4), locating piece (7) from left to right sets gradually.
Using method: first place workpiece to be processed, by the circle hole sleeve of back fork on suit cylinder, and make locating piece snap in the prong of back fork, the lower surface due to back fork is matsurface, adopts the second vertical cylinder to use as pivoted shoe; Afterwards, restart the first vertical cylinder and the second vertical cylinder, just in time be bearing in the lower surface of back fork after the push rod of the second vertical cylinder is protruded upward, be just in time bearing in the waist of back fork after the push rod of the first vertical cylinder protrudes upward, now Set and Positioning completes; The facing cutter of vertical knee-type milling machine is to lower feeding, thus the upper plane of processing back fork.After machining, the first vertical cylinder, the second 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, mounting portion its localization part downward bending relatively of described locating piece (7).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, and 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 described first vertical cylinder (4) 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, designs ingenious, is located by clamping workpiece by this 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 using state figure of the present invention.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
As shown in Figure 1, the quick clamping mechanism of plane on a kind of milling back fork, is made up of stand 1, tool base plate 2, the vertical cylinder 4 of two-side supporting block 3, first, riser 5, suit cylinder 6, the vertical cylinder 8 of locating piece 7, second 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 the first vertical cylinder 4.
Between tool base plate 2 and stand 1, be provided with the first vertical cylinder 4, the top of tool base plate 2 is installed with riser 5 near the position of tool base plate 2 leading edge.
The rear wall of riser 5 is installed with perpendicular to the suit cylinder 6 of rear wall, mates the locating piece 7 that also can stretch in back fork prong with back fork prong width.Second vertical cylinder 8 is installed above tool base plate 2, when the circle hole sleeve of back fork is on suit cylinder 6, when locating piece 7 stretches in the prong of back fork simultaneously, just in time be bearing in the lower surface of back fork after the push rod of the second vertical cylinder 8 protrudes upward, after the push rod of the first vertical cylinder 4 protrudes upward, be just in time bearing in the waist of back fork.The push rod of the second vertical cylinder 8, the push rod of the vertical cylinder 4 of suit cylinder 6, first, locating piece 7 from left to right set gradually, thus ensure that back fork on riser during clamping, and upper plane is positioned at left side and upward, and on the right side of prong is positioned at.The push rod that first, second vertical cylinder 4,8 all can protrude upward with one.
Preferably, 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, mounting portion its localization part downward bending relatively of locating piece 7.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 the first vertical cylinder 4 is curved surface, and with the SURFACES MATCHING of selector fork supported portion position.
Shown in composition graphs 1, Fig. 2, before processing, first place back fork 9 to be processed, by the circle hole sleeve of back fork 9 on suit cylinder 6, and make locating piece 7 snap in the prong of back fork 9; Afterwards, restart the second vertical cylinder 8 and the first vertical cylinder 4, just in time be bearing in the lower surface of back fork 9 after the push rod of the second vertical cylinder 8 is protruded upward, be just in time bearing in the waist of back fork 9 after the push rod of the first vertical cylinder 4 protrudes 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, the first vertical cylinder 8 of vertical cylinder 4, second and facing cutter return, then the back fork 9 machined is taken off.
