Abstract
The utility model relates to a device for taking out screw taps, which is particularly used for taking out the parts of the screw taps broken off in workpieces, and the utility model is composed of pulling claws extended in chip flutes at the cutting parts of the screw taps and flat handles which can be clamped and rotated conveniently. The problem that the parts of the screw taps broken off in the workpieces are difficult to take out is completely solved. The utility model has the advantages of reasonable structure, easy fabrication and low cost.
Description
The utility model relates to a kind of screw tap driver-extractor, belongs to the machine tools technical field.
In machining, with the screw tap tapping is the most frequently used a kind of method, and owing to reasons such as the intensity of screw tap itself and misoperations, screw tap twists off and remains in workpiece and be difficult to avoid, bring a very thing of trouble like this, promptly must take out the fracture of wire awl in order not scrap workpiece, at present, the method for employing mainly contains four kinds, the first recoils with punching pin, this needs rich experience, and speed is slow and success is high, and the time is long; It two is to break screw tap into pieces, the low and destructible workpiece screw thread of efficient; It three is to use spark machined, complex process, cost height; It four is that bore with carbide drill annealing back, influences workpiece quality because of workpiece in the annealing process is heated simultaneously, and the cost height, and the time is long.Comprehensive above-mentioned four kinds of methods all can not be dealt with problems effectively, thereby make so minor accident and become the thing of trouble of one of machined people of fracture of wire awl.
The purpose of this utility model is exactly will design a kind of being specifically designed to take out the instrument that the fracture of wire awl remains in part in the workpiece, makes the work of taking out residual fracture of wire awl very convenient easily.
To achieve these goals, the utility model has adopted following technical scheme: the screw tap driver-extractor, and by forming for pusher dog [1] that can stretch into screw tap blade chip pocket and the flat handle [2] of being convenient to the clamping rotation.
Owing to adopted technique scheme, the utility model has ideally been realized its goal of the invention, has thoroughly solved the screw tap problem that part in workpiece is difficult to take out of breaking, and it is simple and reasonable, be easy to make, and cost is low, has practicality widely.
Description of drawings:
Accompanying drawing 1 is the utility model concrete structure schematic diagram
Accompanying drawing 2 is upward views of the utility model accompanying drawing 1
Embodiment:
Accompanying drawing has been described an embodiment of the present utility model, and with reference to accompanying drawing, the screw tap driver-extractor is by forming for pusher dog [1] that can stretch into screw tap blade chip pocket and the flat handle [2] of being convenient to the clamping rotation.
The profile of each pusher dog [1] is the real cylinder that matches with screw tap chip pocket profile.
Pusher dog [1] is parallel uniform three.
Flat handle [2] is six sides.
Using method of the present utility model is as follows:
1, selects for use and the supporting screw tap driver-extractor of fracture of wire awl;
2, screw tap driver-extractor pusher dog is inserted in three chip pocket of fracture of wire awl;
3, block the swing handle position with spanner, reverse rotation, the screw tap method is identical with moving back, and then can take out the fracture of wire awl;
4, spanner then inserts the swing handle position and impacts in the gong silk cutter as can not getting, and screws out with impacting gong silk cutter;
5, permit not in the character of workpiece, can drip a little strong acid and go in the fracture of wire awl to corrode two days, then easier taking-up fracture of wire awl.
