Abstract

The utility model discloses a tapping guide apparatus comprising a guide sleeve, wherein a guide hole is arranged in the guide sleeve, and the tapping guide apparatus further comprises a magnetic seat, wherein the bottom surface of the magnetic seat is a flat surface, and a guide sleeve is connected on the magnetic seat, and the axial cord of the guide hole is perpendicular to the bottom surface of the magnetic seat. The magnetic seat can be utilized to be conveniently absorbed on the surface of a to-be processed work piece (materials, such as steel and the like), which enables the guide hole on the guide sleeve to be aligned to a bottom hole on the work piece, the tapping can be carried out only through inserting a screw tap, since the guiding function of the guide sleeve, the screw tap can be rightly inserted into the bottom hole for tapping. The tapping guide apparatus guarantees the perpendicularity of the tapping and improves the efficiency and the pass percent of the tapping, the screw tap is not easy to break, and the tapping guide apparatus has the advantages of simple structure and convenient use.

Description

The tapping guider

Technical field

The utility model relates to a kind of tapping aid, guarantees the steering tool of screw tap perpendicularity when being specifically related to a kind of tapping.

Background technology

Tapping is to utilize screw tap to process the process of screwed hole on the workpiece of accomplishing fluently bottom outlet, and in machining, assembling or maintenance process, tapping is the work that often will do.In tapping process, the perpendicularity between screw tap and the machined surface that is threaded there is higher requirement, generally require perpendicularity about 0.05～0.1mm, could guarantee the axiality between screw tap and the bottom outlet like this.

Yet,, can only control the direction of screw tap by range estimation because tapping process is manual finishing, after screw tap inserts bottom outlet, be difficult to guarantee the axiality of screw tap and bottom outlet, in tapping process, just be easy to like this cause screw tap to fracture, the pore-forming qualification rate is low, and the activity duration is long, and efficiency is low; And in a single day screw tap breaks in bottom outlet, just can't take out, and may cause whole work-piece to scrap.

The utility model content

The technical problems to be solved in the utility model provides a kind of tapping guider, can guarantee the correct direction of screw tap when tapping.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of tapping guider, comprise a fairlead, be provided with pilot hole in the fairlead, also comprise a magnet base, the bottom surface of magnet base is the plane, and described fairlead is connected on the magnet base, and the bottom surface of the axis of pilot hole and magnet base is perpendicular.

The beneficial effects of the utility model are: utilize magnet base can be adsorbed on the surface of workpiece to be processed (material such as iron and steel) easily, make the bottom outlet on the pilot hole alignment pieces on the fairlead, insert screw tap and just can carry out tapping, because the guide effect of fairlead can be inserted in the bottom outlet screw tap with correct direction and is carried out tapping.Guaranteed the perpendicularity of tapping, screw tap is frangibility not, improves tapping efficient and qualification rate.The utility model also has advantage simple in structure, easy to use.

As improvement of the technical scheme, described fairlead removably is connected on the magnet base.Can change the fairlead in different apertures according to the size of screw tap like this.

Preferably, described magnet base is provided with through hole, and described fairlead can be connected in this through hole with plugging.

Further, described magnet base and fairlead are revolving body.

Preferably, described magnet base comprises housing and is installed in the interior magnet of housing.

As improvement of the technical scheme, the end face of described magnet base also is the plane, and the side of described fairlead is provided with the tabular projection, the cooperation that contacts with the end face of magnet base of the bottom surface of this tabular projection.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the sectional structure schematic diagram of the utility model tapping guider.

Fig. 2 is the vertical view of magnet base part.

Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model tapping guider.

The specific embodiment

As Figure 1-3, a kind of tapping guider of the present utility model comprises a fairlead 2 and a magnet base 3, and fairlead 2 and magnet base 3 are revolving body.Be provided with pilot hole 21 in the fairlead 2, the center of magnet base 3 is provided with circular through hole 31, and the diameter of through hole 31 is identical with the external diameter of fairlead 2, and fairlead 2 can insert in the through hole 31 easily, thereby is connected with magnet base 3; Also can pull out easily and change fairlead 2.

Magnet base 3 is made of housing 33 and the magnet 34 that is installed in the housing, and the bottom surface 35 of magnet base is the plane, and when fairlead 2 was connected on the magnet base 3, the axis of pilot hole 21 and the bottom surface of magnet base 35 were perpendicular.

A kind of structure of more optimizing is to be provided with tabular projection 22 in the side of fairlead 2, the end face 32 of magnet base also is the plane, when fairlead 2 inserts magnet base 3, the cooperation that contacts with the end face of magnet base 32 of the bottom surface of this tabular projection 22, can increase the contact area of fairlead 2 and magnet base 3 like this, help guaranteeing the perpendicularity between the bottom surface 35 of the axis of pilot hole 21 and magnet base.

When tapping, magnet base 3 is adsorbed on the surface of iron and steel to be processed (also can be other ferromagnetic material) workpiece, make the bottom outlet on pilot hole 21 alignment pieces on the fairlead 2, screw tap 1 is inserted along pilot hole 21 in the bottom outlet of workpiece and just can carry out tapping.The diameter of pilot hole 21 and the diameter of screw tap adapt, because pilot hole 21 is vertical with the bottom surface 35 of magnet base, just guaranteed that screw tap 1 also is vertical with the surface of workpiece, so just guaranteed the correct direction of screw tap, improved tapping efficient and qualification rate, the phenomenon that screw tap is twisted into two parts can not take place.

When adopting the screw tap of different-diameter,, very easy to use as long as change fairlead with different pilot hole internal diameters.
