Abstract
The utility model discloses a kind of drill bit processing jigs, and including chuck, locating piece and clamping device, array opens up three bar shaped grooves equidistantly arranged on the chuck, and bar shaped groove extends outwardly from the core of chuck；It is slided in the bar shaped groove and is equipped with locating piece；The chuck rear end is equipped with clamping device, pressing device includes main body, rear cover, pipe fitting, the first ring seal circle, the second ring seal circle, dovetail groove type inclined wedge, tricyclic sealing ring, pilot bushing, protective cover, gripping block, auxiliary support bar and dustband；The utility model is guaranteed on the premise of driving dovetail groove type inclined wedge, make the strength that gripping block holds out against drill bit smaller, it will not be deformed drill bit, when drill bit is processed, if drilling rod is applied to one larger power of gripping block, due to the effect of Self-locking angle, auxiliary support bar will not generate displacement, ensure to hold out against and support drill bit always, the generation for preventing cutting from shaking.
Description
Technical field
The utility model is related to a kind of fixtures, are specifically a kind of drill bit processing jig.
Background technology
Cutter is the instrument that machining is used in machine-building, also known as cutting element, and most of cutter is that machine is used
, but also have hand, since the cutter used in machine-building is substantially all for cutting metal material, so " cutter " one
Word is generally just interpreted as metal cutting tool, drill bit be on solid material drilling go out through hole or blind hole, and can be to having
Hole reaming cutter.Common drill bit mainly has fluted drill, chit drill, centre drill, depth drill and cylindrical drill.
At present, inclined wedge locking auxiliary is held out against always by oil pressure mostly in the fixture of the prior art for processing drill
The mode of supporting rod, for such mode with the fluctuation of oil pressure, Auxiliary support pressure can also generate fluctuation, be easy to cause clamping and lose
Effect；Spring reset is relied primarily in the prior art, but since spring force is more difficult to control, and spring easily loses in use
Elasticity is gone, so not being very reliable by spring reset.
Utility model content
The purpose of this utility model is to provide a kind of drill bit processing jig, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical solution：
A kind of drill bit processing jig, including chuck, locating piece and clamping device, array opens up three on the chuck
A bar shaped groove equidistantly arranged, and bar shaped groove extends outwardly from the core of chuck；It slides and sets in the bar shaped groove
There is locating piece；The chuck rear end is equipped with clamping device, and pressing device includes main body, rear cover, pipe fitting, the first ring seal
Circle, the second ring seal circle, dovetail groove type inclined wedge, tricyclic sealing ring, pilot bushing, protective cover, gripping block, Auxiliary support
Bar and dustband, main body are fixedly connected with chuck；The dovetail groove type inclined wedge is fitted in the endoporus of main body, dovetail groove type
Inclined wedge can be moved up and down along main body, and rear cover is mounted in the endoporus of main body one end, and pipe fitting covers after being mounted on, and and main body
Connection, main body other end installation protective cover, pilot bushing are mounted on body side, and the outer dovetail of auxiliary support bar lower part is matched somebody with somebody
It closes on the interior dovetail groove of dovetail groove type inclined wedge, the outer circle of auxiliary support bar is fitted on the endoporus of pilot bushing,
Auxiliary support bar, which is oppositely oriented bushing, can do relative linear motion, and gripping block is fixedly mounted on auxiliary support bar；Gripping block with
Locating piece is fixedly connected.
Further, the second ring seal circle and tricyclic sealing are installed in the groove of the dovetail groove type inclined wedge
Circle.
Further, the first ring seal circle is installed in the groove of the rear cover.
Further, the bar shaped groove tail end extends outside chuck.
Further, the chuck end face is upper is equipped with symmetrical graduation mark in bar shaped groove both sides.
Further, dustband is installed in the groove of the pilot bushing.
Compared with prior art, the utility model is guaranteed on the premise of driving dovetail groove type inclined wedge, makes gripping block top
The strength of tight drill bit is smaller, will not be deformed drill bit, when drill bit is processed, if drilling rod is applied to gripping block one
Larger power, due to the effect of Self-locking angle, auxiliary support bar will not generate displacement, it is ensured that hold out against and support drill bit always, prevent
Only cut the generation of vibrations.
