Abstract
The utility model discloses a small screw hole tapping tool. The small screw hole tapping tool comprises a screw tap clamping handle (1) and a screw tap (2) as well as also comprises a guide ring (3) for locating, wherein a square hole (4) corresponding to the screw tap (2) is formed on the screw tap clamping handle (1); and a square handle (5) of the screw tap (2) is connected with the square hole (4) in a matched way. The small screw hole tapping tool disclosed by the utility model is located by the guide ring so that the perpendicularity of the threaded hole is guaranteed; in addition, the movable clamping of the general screw tap clamping handle is changed into square hole fixing clamping so that firmness for clamping and uneasiness for the screw tap to fall off are obtained; meanwhile, the special screw tap clamping handle is adopted according to the shell part space so that the machining requirement of the special space position is satisfied. The problems that intervention is easy to generate, the screw tap is easy to crack or the threaded hole is easy to be inclined during machining the shell part in the prior art, in particular the problem that the threaded hole cannot be machined because the intervention is easy to generate by using the traditional tool due to the space limitation during tapping the thread in the shell part, are preferably solved.
Description
Technical field
the utility model relates to a kind of little screw tapping frock, belongs to screw processing tool technical field.
Background technology
When
process housing part minor thread hole (below the M5) with conventional screw tap grip shank; Because the less conventional grip shank of screw tap is easy to generate interference when the processing housing part; Be easy to generate screw tap fracture or screwed hole and be prone to produce, particularly in housing part, in attacking the system screw thread owing to receive its limited space property; Adopt conventional frock to be easy to generate interference, cause screwed hole to process.
Summary of the invention
The purpose of
the utility model is, a kind of little screw tapping frock is provided.The processing of minor thread hole in housing part to below the M5 remedies and receives limited space property, and screwed hole generally is difficult to guarantee vertical, and the easy interference that produces of screw tap grip shank, improves the working (machining) efficiency of part, overcomes existing technical deficiency.
The technical scheme of the utility model
a kind of little screw tapping frock comprises screw tap grip shank and screw tap; Also comprise the guide collar that is used to locate; The screw tap grip shank is provided with and the screw tap corresponding square holes, and the square handle and the square hole of screw tap are connected.
In
aforesaid little screw tapping frock, the thickness of said guide collar is not less than 1/2nd of the screwed hole degree of depth.
In
aforesaid little screw tapping frock, the hardness of said guide collar is greater than the hardness of screw tap.
In
aforesaid little screw tapping frock, the length of said screw tap grip shank is the serial grip shank autocratic according to usage space.
compared with prior art, the utility model has guaranteed the perpendicularity of screwed hole through guide collar location; Activity clamping with general screw tap grip shank changes square hole geometrical clamp extension in addition, and clamping is firm, and screw tap is not easy to come off; Adopt special-purpose screw tap grip shank according to the space of housing part simultaneously, to satisfy the process requirements of special space position.Be easy to generate interference when well having solved prior art processing housing part; Being easy to generate screw tap fracture or screwed hole is prone to produce; Particularly in housing part; In attacking the system screw thread,, adopt conventional frock to be easy to generate interference, the problem that causes screwed hole to process owing to receive its limited space property.
Description of drawings
Fig. 1 is the basic structure sketch map of the utility model.
Be labeled as among
figure: 1-screw tap grip shank, 2-screw tap, 3-guide collar, 4-square hole, 5-side's handle.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.
a kind of little screw tapping frock, as shown in Figure 1.Comprise screw tap grip shank 1 and screw tap 2; Also comprise the guide collar 3 that is used to locate; The thickness of guide collar 3 is not less than 1/2nd of the screwed hole degree of depth.The hardness of guide collar 3 is greater than the hardness of screw tap 2.The length of said screw tap grip shank 1 is the serial grip shank autocratic according to usage space.Screw tap grip shank 1 is provided with and screw tap 2 corresponding square holes 4, and the square handle 5 and the square hole 4 of screw tap 2 are connected.
The method for using of the utility model
when carrying out hole processing, earlier make a call on the part to be processed diameter less than screwed hole at the bottom of directly bottom outlet; Size and screw thread locus of living in according to screwed hole are selected suitable screw tap 2 and suitable screw tap grip shank 1 for use; With reference to figure 1; In the square hole 4 on the 5 insertion screw tap grip shank 1 of the square handle on the screw tap 2; Side's handle 5 is an interference fits with square hole 4, and certain tightness is arranged during insertion, prevents to come off voluntarily after screw tap 2 from inserting.Hold the bottom outlet surface of position that guide collar 3 is positioned part to be processed with hand then,, screw in bottom outlet and carry out tapping, can guarantee that perpendicularity is within 0.02 scope the centre bore of screw tap 2 insertion guide collar 3.
