Specific implementation mode
The utility model is described in further detail with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
Include the workbench 1 with supporting leg 2, the work referring to a kind of Fig. 1 to shift fork bore hole fixture shown in Fig. 4
1 top of platform is provided with shift fork fixed seat 4, and 4 upper surface of shift fork fixed seat is provided with to be clamped the groove 8 at shift fork fork angle,
A relief hole 12 is additionally provided in the shift fork fixed seat 4, the workbench 1 is fixed with a guide sleeve 9, institute in relief hole 12
It states 9 inner wall of guide sleeve and is provided with guide protrusions 17, the lower surface of the workbench 1 is fixedly installed cylinder 3, the cylinder 3
A upright bar 6 is rotatably connected on cylinder rod 10, the upright bar 6 is connected in guide sleeve 9 across workbench 1, is set in the upright bar 6
It is equipped with and is connected with compression cross bar 7 with 17 matched helicla flute 16 of guide protrusions, 6 top of the upright bar.
Process is as follows when in use for the utility model, and angle is pitched due to being provided with clamping shift fork in shift fork fixed seat 4
Groove 8 after positioning is completed, starts cylinder so shift fork 13 can accurately be positioned by groove 8, cylinder rod to
Lower contraction will drive upright bar 6 also to move down, since upright bar 6 is rotatably connected on cylinder rod, so in decline at this time
Meanwhile, it is capable to be rotated by helicla flute 16 thereon and guide protrusions 17, finally, when cylinder rod reaches bottom
It waits, compresses cross bar and be just pressed on relief hole 13, after relief hole 13 is compacted, start the boring cutter on lathe, it can be right
Connecting hole carry out boring operation, when bore hole completion after, cylinder rod rise, upright bar 6 rise while rotate, finally from
Relief hole 13 is opened, at this point, again removing relief hole 13, puts next relief hole 13 for waiting for bore hole.The utility model
Cylinder rod and upright bar may be used various structures and be rotatablely connected, as shown in figure 4, being fixedly connected with a sleeve on cylinder rod
18, sleeve 18 is interior to be fixedly installed a rolling bearing 19, and upright bar interference is connected on rolling bearing inner ring, and by flange 20 and turns
The inner ring of dynamic bearing 19 is mutually clamped (as rotation water pipe head common on the market uses this principle).
Further, the helicla flute 16 is that can to compress the helicla flute 16 for rotating 90 degree.When upright bar 6 rotates 90 degree
When, it compresses cross bar 7 and also rotates 90 degree, this set so that the piece uploading or pickup that operator can be more convenient.
Further, the shift fork fixed seat 4 includes supporting table and fixed plate 5, and the fixed plate 5 is threaded in support
On platform.Being divided due to shift fork fixed seat 4 can be consolidated for two parts so when in face of the shift fork of different model by replacing
