Description
Technical field
The utility model relates to a kind of manual taking-up instrument, relates in particular to a kind of fracture fracture of wire awl taking-up instrument of screw tap of tapping process that is used for taking out.
Background technology
In machining, when utilizing the screw tap machining screw, tend to run into the screw tap situation in workpiece that fractures, product scrap loss than screw tap, more make us feeling to regret.Generally, take out the screw tap that fractures in screwed hole, the method for getting fracture of wire awl has spark erosion machining and welding, and spark machined machines away the matrix of part and faulty part easily, and expense high, can't process at the scene.Welding is unreliable, often damages parts itself.For the more shallow screw tap of screwed hole in workpiece that fractures, according to circumstances some easy screw tap withdrawing devices that adopt are back-outed the fracture of wire awl come as using clamp or homemade steel wire to insert in the screw tap groove more.Then owing to use the model of screw tap different; Its diameter is different; More homemade simple and easy fracture of wire awl withdrawing device difficulty or ease guarantee the fracture of wire awl of taking-up different model, and because the user twists force direction difference to some extent, the fracture of wire awl inner hole thread that easy damage has been attacked in the taking-up process.
The utility model content
For the weak point in addressing the above problem, the utility model provides a kind of fracture of wire awl taking-up instrument.
In order to solve above technical problem, the technical scheme that the utility model adopts is: a kind of fracture of wire awl taking-up instrument, and it is made up of clamping device and fast rotational device; Clamping device is made up of jaw, drill body, gear ring, push rod, compression spring, push rod flexible adjustment nut and push rod; The fast rotational device is pulled, ratchet mechanism, is tightened handle and form by sleeve; Ratchet mechanism is made up of ratchet, back-moving spring, ratchet;
Clamping device is provided with the collet automatic discharge mechanism that is made up of push rod, compression spring, push rod flexible adjustment nut and push rod;
Push rod is installed in the fixed handle centre, and the diameter of push rod is more smaller than the clamping diameter of chuck; The compression spring that extrudes the push rod effect has been equipped with at the minor diameter position of push rod back.
Be provided with between gear ring and the jaw and be used for the transmission mechanism that jaw opens and closed thread engagement forms.
Collet automatic discharge mechanism is made up of push rod, compression spring, push rod flexible adjustment nut and push rod; Collet automatic discharge mechanism is positioned at the center of fixed handle.
The beneficial effect of the utility model is: the utility model is easy to use, and reliable operation can be taken out the screw tap of in the screwed hole different-diameter of fractureing by hand under the situation of defective work piece not.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
Among the figure: the 1-jaw; 2 drill bodies; The 3-gear ring; The 4-push rod; 5-compresses spring; The flexible adjustment of 6-push rod nut; The 7-sleeve is pulled; The 8-ratchet; 9-tightens handle; The 10-fixed handle; The 11-push rod; The 12-back-moving spring; The 13-ratchet.
The specific embodiment
The utility model comprises that the clamping device that is formed by jaw 1, drill body 2, gear ring 3, push rod 4, compression spring 5, the flexible adjustment of push rod nut 6, push rod 11 reaches by sleeve and pulls 7, ratchet mechanism, tightens the fast rotational device that handle 9 forms and form.Ratchet mechanism is made up of ratchet 8, back-moving spring 12 and ratchet 13.Clamping device is provided with the collet automatic discharge mechanism that is made up of push rod 4, compression spring 5, push rod flexible adjustment nut 6 and push rod 11; Push rod 4 is installed in fixed handle 10 centres; Push rod 4 diameters are more smaller than the clamping diameter of chuck; Compression spring 5 is equipped with at the minor diameter position of push rod 4 back, and push rod 11 is equipped with in push rod 4 fronts, and push rod 11 always is forced out.The afterbody of push rod 4 has screw thread, stretches through push rod and adjusts the extension elongation that nut 6 can be regulated push rod 11.When the screw tap that fractures is back-outed, loosening fixed handle 10, push rod 4 stretches out under 5 effects of compression spring, automatically the fracture of wire awl is discharged.
The utility model is when being used for taking out the screw tap that fractures at the workpiece screwed hole; The jaw 1 of clamping device is placed in the screw tap chip area that has broken; With hand rotational fixation handle 10; Drive gear ring 3 and rotate, gear ring 3 moves jaw 1 downwards through worm drive in the inclined hole of drill body 2, thereby makes jaw 1 clamp the screw tap that fractures in screwed hole.The fast rotational device is cooperated through turret head to be installed on the turret head of drill body 2 again, rotate along positive direction with hand and tighten handle 9, clamping device rotates under the drive of tightening handle 9, thereby the fracture of wire awl is back-outed.Repeatedly rotate when tightening handle 9 at needs, can be with tightening handle 9 earlier along turning over certain angle in the other direction, at this moment ratchet 13 is beated on ratchet, and ratchet 8 is motionless, and then forward rotation is tightened handle 9.
The clamping device of the utility model; Be provided with collet automatic discharge mechanism; Push rod is installed in the fixed handle centre, and the push rod diameter is more smaller than the clamping diameter of chuck, and the compression spring is equipped with at the minor diameter position of push rod back; Push rod is equipped with in the push rod front, under spring action, push rod always is forced out.The afterbody of push rod has screw thread, stretches through push rod and adjusts the extension elongation that nut can be regulated push rod.When the screw tap that fractures is back-outed, loosening fixed handle, push rod stretches out under the compression spring action, automatically the fracture of wire awl is discharged.
Clamping device of the utility model and fast rotational device connect together through the turret head cooperation, can clamping device and fast rotational device be separated when not using, and are convenient to depositing and safeguarding of instrument.
The preferred embodiments that is merely the utility model of this specification lists, equivalent technologies and the structure conversion done under all operation principle and thinkings at the utility model all are regarded as the protection domain of the utility model.
