Abstract
The utility model relates to a screw tap, and belongs to a metal cutting processing tool. A through hole is arranged at the handle portion of the screw tap, and the through hole is matched with a screw. The connecting part of the through hole and the screw is capable of preventing slipping in the process of transmitting a torque. The screw tap has the advantages of solving the problem of the slipping of a drill chuck in the working process, improving work efficiency when working, preventing the drill chuck from being damaged and reducing the unnecessary loss.
Description
Technical field
The utility model relates to a kind of screw tap, belongs to a kind of metal cutting machining tool.
Background technology
In the operation of machining, tapping is last procedure.For increasing work efficiency, the modern times are processed substantially all steering box tapping, and well-known screw tap clamps transmitting torque by drill chuck.In process; although machine is fast with tapping speed; but often because the relation of processing parts material; and cause between the drill chuck and skid and can't transmitting torque; just must shut down and again beat drill chuck to step up screw tap this moment; cause that drill chuck is impaired serious, both reduced operating efficiency, increased again production cost.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art part and a kind of screw tap is provided, thereby the skidding that has overcome in the process of hole reduces drill chuck damaged phenomenon and Decrease production cost.
The purpose of this utility model is to solve by following technical proposal:
A kind of screw tap is characterized in that: the shank at screw tap is provided with through hole, and the central shaft of the central shaft of through hole and screw tap shank intersects and be vertical.
Screw tap described in the utility model also comprises the screw that matches with through hole.
Screw tap described in the utility model, the quantity of through hole are 1 ~ 4.
Compared to existing technology, the utlity model has following advantage:
1, loads conveniently, in the corresponding machine hole of only screw tap need being packed into, with the through hole on the corresponding machine of the through-hole alignment of screw tap, screw is pacified into getting final product, in use can not skid.
2, do not need to stop frequently machine and beat chuck, both saved the time, improved the service life of drill chuck, reduced production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the D-D cutaway view of Fig. 1.
Fig. 3 is the structural representation of screw (3).
The specific embodiment
Below in conjunction with accompanying drawing the utility model solution is described in detail.
As shown in Figure 1, be provided with through hole 2 at screw tap shank 1, be provided with screw thread in the through hole 2.Fig. 2 is through hole 2 position cross-sectional views, and the central shaft of the central shaft of through hole 2 and screw tap shank 1 intersects and be vertical.Fig. 3 is the screw 3 that through hole 2 matches.Screw 3 peaces are entered in through hole 2, fixedly screw tap.The effect of skidding of preventing is played at screw 3 and the handing-over position of through hole 2 in the transmitting torque process.
When tapping was used, the screw tap transmitting torque directly relied on drill chuck, and the antiskid function that through hole is set on this basis again skids to prevent screw tap, increased the operating efficiency of screw tap.
Claims (3)
1. screw tap, it is characterized in that: the screw tap shank is provided with through hole, and the central shaft of the central shaft of through hole and screw tap shank intersects and is vertical.
2. screw tap according to claim 1 is characterized in that: also comprise the screw that matches with through hole.
3. screw tap according to claim 1, it is characterized in that: the quantity of through hole is 1 ~ 4.
