Abstract
The utility model discloses a manual tapping device with guiding function. The manual tapping device with guiding function comprises a screw tap component and a guiding sleeve. The screw tap component comprises a screw tap and a screw tap handle which is fixedly sleeved at the shank of the screw tap. The guiding sleeve is in a columned structure and provided with through holes along the axial direction. The through holes of the guiding sleeve are matched with the shank of the screw tap in clearance fit and the perpendicularity of the screw tap is maintained by the guiding sleeve in the tapping process. Due to the design of addition of the guiding sleeve, the phenomenon of skewing in the tapping process is effectively avoided.
Description
Technical field
The utility model relates to the parts and components of diesel engine manufacture field, particularly a kind ofly prevents that the hand tapping from attacking the inclined to one side tapping device with guide function.
Background technology
At present, when processing diesel engine parts such as cylinder body, need sometimes by hand tapping to be carried out in certain hole on the parts, at this moment need to use tap wrench.Existing tap wrench structure rotatably compresses this two slide blocks from both sides with two long bolts again for two slide block clamping screw tap shank square toes that have square opening.The artificial long bolt drive screw tap that rotates carries out tapping.Referring to Fig. 1 (slide block, long bolt are illustrated as a whole among the figure), comprise screw tap 1 ' and windeisen 2 '.
There are the following problems for above-mentioned prior art: at first, the square opening of existing tap wrench top shoe only contacts with screw tap shank square toes, cooperates area little, and easily wearing and tearing, and tapping is unreliable; Two long bolts of existing tap wrench are too short with the screw tap head distance, can not guarantee screw tap and vent surface perpendicularity in the tapping process, easily cause the screw inclination of processing, and have a strong impact on screw processing quality; Existing tap wrench because can not guarantee vertically, can reduce screw tap service life in tapping process, also easily cause the screw tap fracture in the tapping process.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art, by increasing the design of fairlead, can effectively to avoid the inclined to one side phenomenon of attacking in the tapping process.
For achieving the above object, the utility model provides a kind of hand with guide function to attack tapping device, comprising: the screw tap assembly, and it comprises screw tap and windeisen, the sheathed shank that is fixed on screw tap of windeisen; Fairlead, it is cylindrical-shaped structure, and fairlead is provided with through hole vertically, and fairlead through hole and screw tap shank are suitable and form matched in clearance, and fairlead keeps the perpendicularity of screw tap in tapping process.
In the technique scheme, windeisen is comprised of slide block and long bolt, and two slide blocks have corresponding square opening and are clamped on the shank square toes of screw tap, and two long bolts rotatably compress respectively two slide blocks from both sides, forms fixing of windeisen and screw tap.
Compared with prior art, the utlity model has following beneficial effect:
1, by increasing the structural design of fairlead, the screw tap that the tapping of going smoothly is used keeps perpendicularity in tapping process, prevents that Manual tapping from attacking partially, guarantees the crudy of screwed hole;
2, simultaneously owing in process, having guaranteed the perpendicularity of screw tap, can make in the process, can not make screw tap generation active force radially, screw tap has been played protective effect, thereby prevent the screw tap fracture that the screw tap out of plumb causes;
3, simple in structure, manufacturing process is succinct, only needs simple car, brill, cuts with scissors, attacks and can finish processing and manufacturing.

The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
Shown in Fig. 2, Fig. 3-1 and Fig. 3-2, hand with guide function of the present utility model is attacked tapping device and is comprised screw tap part and fairlead part, its plug tap partly comprises screw tap 1 and windeisen 2, the concrete structure of windeisen 2 is the slide block clamping screw tap shank square toes that have square opening with two, rotatably compress this two slide blocks from both sides with two long bolts again, drive screw tap by artificial rotation long bolt and carry out tapping.Also not shown among the Split type structure figure of the slide block of aforementioned windeisen and long bolt, only show the overall structure as windeisen among the figure.Fairlead 3 is a cylindrical-shaped structure, and fairlead 3 is provided with through hole 31 vertically, and the external diameter of the diameter of this through hole 31 and windeisen 2 is suitable, and both form matched in clearance.
Screw tap 1 among Fig. 2 are connected with windeisen connect after, insert and can prevent effectively in the through hole 31 in Fig. 3 fairlead 3 that the hand tapping from attacking inclined to one side phenomenon.After inserting fairlead, available tap wrench drives screw tap and carries out tapping.
The utility model is by increasing the structural design of fairlead; the screw tap that the tapping of going smoothly is used keeps perpendicularity in tapping process; prevent that Manual tapping from attacking partially; guarantee the crudy of screwed hole; owing in process, having guaranteed the perpendicularity of screw tap, can make in the process simultaneously, can not make screw tap generation active force radially; screw tap is played protective effect, thereby prevented the screw tap fracture that the screw tap out of plumb causes.The utility model is simple in structure, and manufacturing process is succinct, only needs simple car, brill, cuts with scissors, attacks and can finish processing and manufacturing.
Above disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
