Abstract
The utility model relates to an alternate-tooth screw tap provided with an internal containing groove. The alternate-tooth screw tap comprises a tap body (1), wherein a tap handle (2) is arranged at the bottom of the tap body (1), a through hole (3) is arranged at the bottom of the tap handle (2), the top of the tap body (1) is provided with a chip containing groove (4) which is communicated with the through hole (3), a cutting tap (5) is axially arranged on the outer surface of the tap body (1) and provided with a plurality of tooth threads (6) in the radial direction, each tooth thread (6) comprises a long tooth (7) and a short tooth (8), and the long teeth (7) and the short teeth (8) are arranged at intervals. Due to the fact that the top of the tap body is provided with the chip containing groove, chips can be discharged timely in the thread machining process to be prevented from damaging the screw tap. The long teeth and the short teeth are arranged at intervals on the tooth threads so that cutting resistance is reduced, the screw tap is protected, and service life is prolonged.
Description
(1) technical field
The utility model relates to the interrupted thread tap of tank in a kind of being provided with.
(2) background technology
Screw tap is the conventional tool of processing column shape and conical internal thread, be processing various in, the cutter of small size internal thread, it is simple in structure, and is easy to use, both manually actuated, also can on lathe, work, and uses very extensively aborning.General screw tap head does not have chip pocket at present, and the smear metal meeting that in the process of screw thread, produces contacts with screw tap, thereby screw tap is damaged to some extent; The tooth distance of tooth line and width all are certain, and the stressed and cutting resistance of tooth line is very big, easy abrasion, and service life is short.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and the interrupted thread tap of tank in a kind of being provided with is provided, and in the process of machining screw, can discharge smear metal and cutting resistance is little, thereby avoids damaging screw tap.
The purpose of the utility model is achieved in that
The interrupted thread tap of tank comprises cone in a kind of being provided with, and the bottom of said cone is provided with taper shank; The bottom of said taper shank is provided with through hole, and the top of said cone offers chip pocket, and said chip pocket is connected with through hole; The outer surface of said cone is axially arranged with cutting cone; Radially be provided with a plurality of tooth lines on the said cutting cone, said each tooth line comprises long teeth and brachydont, said long teeth and brachydont separation.
The interrupted thread tap of tank in the utility model is provided with, the cross section of said cone is cylindrical.
Compared with prior art, the beneficial effect of the utility model is:
The interrupted thread tap of tank offered chip pocket at the cone top in the utility model was provided with, and in the process of screw thread processing, can in time discharge smear metal, avoided smear metal to damage screw tap; Long teeth and brachydont separation on the tooth line in the process of screw thread processing, have reduced cutting resistance, have protected screw tap, increase the service life.
(4) description of drawings
Fig. 1 is provided with the interrupted thread tap structural representation of interior tank for the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of tooth line.
Wherein:
Cone 1
Taper shank 2
Through hole 3
Long teeth 7
Brachydont 8.
(5) specific embodiment
Referring to Fig. 1～Fig. 3, the interrupted thread tap of tank comprised cone 1 in the utility model was provided with; The cross section of said cone 1 is cylindrical, and the bottom of said cone 1 is provided with taper shank 2, and said taper shank 2 bottoms are provided with through hole 3; Said cone 1 top offers chip pocket 4, and said chip pocket 4 is connected with through hole 3, and the outer surface of said cone 1 is axially arranged with cutting cone 5; Radially be provided with a plurality of tooth lines 6 on the said cutting cone 5, said each tooth line 6 comprises long teeth 7 and brachydont 8, said long teeth 7 and brachydont 8 separation.
The interrupted thread tap of tank offered chip pocket 4 at cone 1 top in the utility model was provided with, and in the process of screw thread processing, can in time discharge smear metal, avoided smear metal to damage screw tap; Long teeth 7 and brachydont 8 separation on the tooth line 6 in the process of screw thread processing, have reduced cutting resistance, have protected screw tap, increase the service life.
Claims (2)
- One kind be provided with in the interrupted thread tap of tank; Comprise cone (1), it is characterized in that: the bottom of said cone (1) is provided with taper shank (2), and the bottom of said taper shank (2) is provided with through hole (3); The top of said cone (1) offers chip pocket (4); Said chip pocket (4) is connected with through hole (3), and the outer surface of said cone (1) is axially arranged with cutting cone (5), radially is provided with a plurality of tooth lines (6) on the said cutting cone (5); Said each tooth line (6) comprises long teeth (7) and brachydont (8), said long teeth (7) and brachydont (8) separation.
