A kind of drill gun sharpening positioning fixture
The present invention relates to clamping tool for machine work technical fields, are a kind of drill gun sharpening positioning fixtures specifically.
Drill gun upon wear, needs in time correctly sharpening, when sharpening, by drill gun clamping on special fixture, starts sword
Grinding machine adjusts angle, is sharpened, and sharpening must assure that correct geometric angle and position of tool tip every time, existing drill gun
Positioning fixture disassembly installation is inconvenient, and precision is not high.
Chinese invention patent publication No. is a kind of Fixture for sharpening for single-blade drill gun of CN103213039A, discloses one
The drill gun that kind is suitable for minor diameter sharpens positioning fixture, but it is only capable of when adjusting the angle to Fixture for sharpening 4 along the direction A and B
Direction rotates adjustment, can not rotate along the excircle of chuck sleeve 3-2, inflexible for use, and on the other hand, Fixture for sharpening 4 wraps
Fan-shaped cone front and cylindrical rear portion are included, two parts are connected with each other, and are equipped with rifle in 4 center right-to-left of Fixture for sharpening
Mounting hole 4-3 is bored, when sharpening, needs for drill gun to be pierced by from drill gun mounting hole 4-3, then passes through lock-screw 4-1 and locking screw
The fixed drill gun of nail 4-2 uses locking device 3-3 finally, assembled drill gun 5 and Fixture for sharpening 4 are mounted in clamp member
It is fixed, sharpened, Fixture for sharpening and clamp member be it is split type, installing and dismounting is relatively cumbersome, and components are easy to be lost, because of peace
The diameter in hole is filled in 1-3mm, drill gun being not fixed firmly in mounting hole is leaned on, and the time is long, and when processing is easy to loosen, and is influenced
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of drill guns to sharpen positioning fixture, easy for assemble or unload easy,
Machining accuracy is high.
In order to achieve the above objectives, the technological means that the present invention uses are as follows: a kind of drill gun sharpening positioning fixture, including fixture sheet
The support portion of body and stationary fixture ontology, the chuck body includes the body upper part and body lower part being oppositely arranged, described
Body lower part is fan-shaped cone, and top is equipped with arc groove, and the body upper part bottom end is equipped with cone angle；The support portion packet
Support plate and branch fastener are included, is equipped with sliding slot in the middle part of the support plate, the branch fastener is connected in sliding slot, and the body upper part is logical
It crosses a fixed block to connect with support plate, the body lower part is fixed on branch fastener.
Further, there is the gap passed through for drill gun between the arc groove and cone angle.
Further, the support plate is to be flexibly connected with branch fastener.
Further, it is locked with fixed block by lock-screw at the top of the support plate.
Further, the support plate bottom is equipped with movable plate, and the movable plate is equipped with lock-screw.
Further, the cone angle is 120 °.
Further, the gun drill diameter is 0.8-10mm.
The beneficial effects of the present invention are: drill gun sharpening positioning fixture of the invention is easy to operate, convenient for fixing；Wherein arc
The cooperation of shape slot and cone angle so that drill gun it is fixed it is more firm, be not easy to loosen, precision it is higher；When being adjusted to drill gun, fixture
Ontology can arbitrarily be adjusted by three different freedom degrees, cooperate L-type guide rail and moving slide board on sliding body to use, according to reality
Border use demand carries out flexibly adjustment.
