Abstract

The utility model discloses a threaded porous drill plate, which is of a cylindrical mould sleeve, wherein the mould sleeve is provided with a drilling hole. The mould sleeve consists of an upper mould sleeve and a lower mould sleeve, and the upper and the lower mould sleeves are combined with each other in a clamping way. A positioning bracket is arranged outside the mould sleeve, and the positioning bracket stays at a free state. The threaded porous drill plate has the advantages that the operation is simple, the production cost is low, rapid processing can be performed on an ordinary drill platform, and the requirement on the operation worker is low; the automatic centering is good, the processing efficiency is high, and the processing efficiency is improved by 2 to 3 times compared with that of the processing center; and the drill plate can be applicable to the processing of different threaded holes only through slight modification according to the requirement of the work piece.

Description

Screw thread porous drill jig
Technical field
The utility model relates to a kind of machining tool, especially a kind of screw thread porous drill jig.
Background technology
One screw mandrel workpiece requires to bore three circular hole and Φ 12.827 holes of intersecting 30 ° of Φ 4.4 mutually after the machining screw.Because drill bit is easy to be offset during the boring of screw thread processing back, and drill bit can't be processed downwards, drill bit is easy to break when serious, and position dimension can't guarantee.With commonsense method is unsatisfactory, because drill bit different position in screw thread, the stress point of drill bit is different, might be monolateral smear metal, might be that many another sides are few on one side, so drill bit is easy to displacement and forces disconnected.In order to address this problem, we begin to consider to divide elder generation to process a hole (footpath at the bottom of silk portion is given and bored first locating hole) with little milling cutter with machining center, and then down hole with drill bit.Though can guarantee precision like this, efficient is too low, and it is also higher that the workman is operated requirement, and production cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of screw thread porous drill jig, and this drill jig guarantees machining accuracy and adapt to produce in batches.
The technical solution of the utility model is: a kind of screw thread porous drill jig, and this screw thread porous drill jig is cylindric die sleeve, die sleeve is provided with boring.Die sleeve becomes Upper Die-sleeve and lower die-sleeve, and upper and lower die sleeve by clamping altogether.Die sleeve is provided with a locating support outward, and the position support is in free state.
Advantage of the present utility model is: simple to operate, production cost is low, and is with regard to the energy rapid processing, less demanding to the operator on common bench drill; Self-centering is good, the working (machining) efficiency height, than work in-process in the heart working (machining) efficiency improve 2-3 doubly; According to the method, as long as require drill jig is revised the processing that just can adapt to various screwed holes a little according to workpiece.

Fig. 1 is the utility model screw thread porous Drilling Jig Structure schematic diagram;
Fig. 2 is the utility model screw thread porous drill jig sectional schematic diagram.
The specific embodiment
A kind of screw thread porous drill jig, this screw thread porous drill jig is cylindric die sleeve 1, die sleeve 1 is provided with boring 2.Die sleeve is inserted in workpiece 4, and when drill bit was down holed by the boring in the die sleeve 12, the hole on the workpiece 4 was also with to getting out, and guaranteed position, hole non-migration, guaranteed dimensional accuracy from face.
1 one-tenth Upper Die-sleeve of die sleeve and lower die-sleeve are just finished clamping as long as upper and lower mould is linked in workpiece 4 and is inserted in the locating support 3 when clamping.
A locating support 3 of the outer design of die sleeve.The drill jig cover is nested in the locating support 3, and the outside of locating support 3 is for a plurality of various fixed angle faces, when with bottom surface A location, with drill jig hole 2a, when with bottom surface B location, with drill jig hole 2b, when with bottom surface C location, with drill jig hole 2c.So just solved the calibration problem in three holes,, therefore realized self-centering again because locating support is in free state.
