Abstract
The utility model provides a cutting tool which completes the drilling and the tapping one time, comprising a drill head, a tap and a handle. When in tapping, the inner hole of the processed workpiece is sleeved on the outer diameter of the drill head of the cutting tool, which plays the function of the positioning and the guiding. Thus, the coaxiality of the inner hole and the screw hole of the processed workpiece is guaranteed. The utility model has the advantages of high precision and high work efficiency. In addition, the cutting tool has no use of changing, and the operation of the drilling and the tapping is completed one time. The utility model is suitable for the industrial and mining enterprise, and is especially suitable for the machine building.
Description
The utility model relates to the metal cutting cutlery, specially refers to the cutlery of boring, tapping.
Process inner bolt hole on drilling machine, lathe, boring machine and some other universal machine tools, often adopt earlier drill bit to be installed in drill chuck or some other clamping device, workpiece is holed, then, den bohrkopf abbauen is changed screw tap carries out tapping to workpiece step.Because the trueness error of drill chuck or some other clamping device, the central axis that can not guarantee clamped drill bit is consistent with the central axis of the screw tap of changing, and when the surperficial out of plumb of the air spots of workpiece or endoporus and workpiece, the guiding of screw tap front portion partly just can not be brought into play its positioning and guiding function fully effectively, causes that the central axis of endoporus of workpiece is not consistent with the central axis of screw.This different entity list has the depth in the screw thread of screw now, and the limiting value that causes screw to bear external force greatly descends.In addition, carrying out the secondary clamping needs the regular hour, and this improves an obstacle of work efficiency beyond doubt.
The purpose of this utility model is in order to overcome above-mentioned every the deficiencies in the prior art, to provide a kind of and can guarantee the screw precision, and can improve the cutlery that can once finish boring, tapping work of 1～3 times of work efficiency.
The purpose of this utility model realizes that by the following method the end of the screw tap of band handle is processed with the drill bit that is combined as a whole with it.Described drill bit comprises fluted drill, chit drill, or reamer.Described screw tap comprises having straight shape chip area and have two kinds of spirality chip areas.Described handle is meant two kinds of garden post staight shank and garden taper shanks.The external diameter of drill bit is by parameters such as external diameter, pitch and the thread form decision of screw tap.The central axis of drill bit and the central axis of screw tap have the axiality requirement to the central axis of handle.
The utility model has the advantages that the precision that can guarantee screw effectively, and 1～3 times of work efficiency can be provided.The utility model is applicable to industrial and mining enterprises, is specially adapted to machinery manufacturing industry.
Below in conjunction with accompanying drawing the utility model embodiment one is elaborated:
Fig. 1 is the outline drawing of the utility model embodiment one.
Fig. 2 is the utility model embodiment one mechanical tapping duty cutaway view.
Referring to Fig. 1, have helical-shaped bit chip area 2 on the drill bit 1, have straight shape screw tap chip area 4 on the screw tap 3, the helical-shaped bit chip area is linked up mutually with straight shape screw tap chip area 4.On the top of screw tap 3, at upper top the be provided with side tenon 6 of machine with garden post staight shank 5, square tenon 6 is to attack screw for hand to establish to machine with garden post staight shank 5.Wherein the external diameter of drill bit is by parameters such as external diameter, pitch and the thread form decision of screw tap.
Referring to Fig. 2, drill jig 10 is clamped machine and is moved down with 5 rotations of cylinder staight shank, drill bit 1 drills workpiece 8, forms an endoporus 7, continues rotation and moves down, screw tap 3 contacts with workpiece 8, begin workpiece 8 tapping, at this moment, drill bit 1 is in endoporus 7, play the positioning and guiding effect of tapping, guarantee that the central axis of screw 9 is consistent with the central axis of endoporus 7.Tapping finishes, and drill chuck 10 drives in the cutlery opposite spin and moves, and finishes the once work of boring, tapping.
Claims (1)
1, a kind of screw tap of being with handle that comprises can once be finished boring, and the cutlery of tapping work is characterized in that the screw tap end is processed with the drill bit that is combined as a whole with it.
