Description
Technical Field
The utility model belongs to the field of machinery, and particularly relates to a valve core overturning type drill jig.
Background
The spool with cylindrical stepped structure, i.e. spool with large and small heads, needs to drill 3 holes in the large end face and 6 holes in the small end face symmetrically, and each hole needs to be positioned precisely. When the valve core of the type is processed, the valve core is difficult to fix first, and when the valve core is drilled, the valve core needs to be accurately turned over, so that the position needing to be drilled is adjusted to be below a drill bit, and the turning angle needs to be very accurate. This places very high demands on the machining, and precise measurements are required during machining to ensure machining accuracy, which greatly reduces machining efficiency and reduces machining accuracy.

Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
As shown in fig. 1 to 4, a valve core turning type drill jig of the present utility model includes a cylindrical jig body 10, and a center hole (not shown) for placing a workpiece 28 to be machined is provided in the jig body 10 so as to penetrate in an axial direction. The cross section of the clamp body 10 is regular hexagon, and each side of the clamp body 10 is provided with a first through hole 12 communicated with the central hole. The clamp body 10 comprises a front end face and a rear end face, a pressing plate 14 is pivotally arranged on the rear end face, and the free end of the pressing plate 14 is fixed on the clamp body 10 through a screw 16; the edges of the press plate 14 do not extend beyond the sides of the clamp body 10 so that the whole is within a regular hexagon for ease of handling on a drill press. The clamp plate 14 is provided with 3 threaded holes that run through, and a fastening screw 18 is all threaded connection in every threaded hole, still sets up 3 second through holes 20 that communicate the centre bore on the clamp plate 14, and the threaded hole sets up with the second through hole 20 is crisscross.
A drill sleeve 22 is disposed within each of the first and second through holes 12, 20. The drill sleeve 22 is a cylindrical structure made of teflon to protect the drill bit and the holder body 10.
Further, a convex pivot table 24 and a fixing table 26 are provided on the rear end face, the pressing plate 14 is pivotally connected with the pivot table 24, and a threaded hole for connecting the screw 16 is provided on the fixing table 26.
When the clamp is used, the clamp 14 is opened, the workpiece 28 is placed in the clamp, then the clamp 14 is closed, and the screw 16 locks the clamp 14; the three fastening screws 18 are rotated against the workpiece 28 to compress the workpiece 28. The jig body 10 is then put under the drill, and drilling is performed at the positions of the first through-holes 12 and the second through-holes 20. Because the locations of the first and second through holes 12 and 20 are designed to be accurate in advance, the drilled locations of the finished product are also very accurate without requiring measurement.
