Abstract
The invention discloses a drilling-tapping integrated composite screw tap comprising a handle portion and a blade portion. The key lies in that the blade portion is composed of a drill at an end portion thereof and a screw tap in the vicinity of the handle portion. The front portion of the drilling-tapping integrated composite screw tap is in the form of combination of the drill and the screw tap, so that screw thread tapping can be realized without changing a cutter after the drilling of a hole; the dispersed steps are rationally centralized, so that the number of steps is reduced and the flow is simplified; besides, the time of loading, changing and replacing the cutter is saved; the number of special machine tools and special clamps is reduced; the production line is shortened; the equipment design is simplified; and the production efficiency is improved; moreover, the drilling-tapping integrated structure also ensures the accuracy of processing, so that the quality of product is guaranteed. As the drill and the screw tap are combined with each other, the drilling-tapping integrated composite screw tap of the invention is capable of effectively improving the working efficiency of processing the internal thread, and also reducing the production cost while ensuring the quality of product.
Description
Technical field
The invention belongs to cutter manufacturing technology field, specially refer to a kind of brill and attack the one combined tap and drill.
Background technology
The processing method of tradition internal thread is to process thread Pilot hole with suitable drill bit earlier, and then remove to attack the system screw thread with screw tap, its shortcoming is: operation is disperseed, required lathe and operation are more, more the number of times of bit change and screw tap is frequent, and not only productivity ratio is low, and the axiality of drill bit and screw tap is difficult to guarantee after the tool changing, influence product quality, on producing, cause inconvenience.
Summary of the invention
The objective of the invention is to propose a kind of brill and attack the one combined tap and drill, can effectively improve the operating efficiency of machining internal thread, when guaranteeing product quality, can also reduce production costs.
Brill of the present invention is attacked the one combined tap and drill and is comprised shank and blade, and key is that described blade is made of the drill bit of its end and the screw tap of close shank.
The anterior combining form that adopts drill bit and screw tap of the present invention, after boring, need not tool changing and can realize attacking the system screw thread, the operation of disperseing is rationally concentrated, shorten the operation number, simplified flow process, save the clamping tool change time, reduced the number of special purpose machine tool and special fixture, shorten production line, simplified the equipment design, improved production efficiency; And bore the structure attack one and also guaranteed the precision of its processing, thereby guaranteed product quality.
Further, described drill bit and screw tap are made of along the same spiral slot that it axially is provided with blade.Spiral fluted tap has big cutting anterior angle, cuts briskly, and moment of torsion is little, can avoid because cutting is stopped up causes tipping and scratch workpiece, and the tapping quality is good, and drill bit has identical chip area with screw tap, and chip removal is smooth and easy, helps guaranteeing product quality.
Brill of the present invention is attacked the one combined tap and drill by drill bit and screw tap are combined, and can effectively improve the operating efficiency of machining internal thread, when guaranteeing product quality, can also reduce production costs.
Description of drawings
Fig. 1 is the structural representation that brill of the present invention is attacked the one combined tap and drill.
Among the figure: 1, shank; 2, blade; 3, drill bit; 4, screw tap.
The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment.
Embodiment 1:
As shown in Figure 1, the brill of present embodiment is attacked the one combined tap and drill and is comprised shank 1 and blade 2, and blade 2 is made of the drill bit 3 of its end and the screw tap 4 of close shank, and drill bit 3 and screw tap 4 are made of along same spiral slot that it axially is provided with blade 2.
The blade 2 of combined tap and drill adopts the combining form of drill bit 3 and screw tap 4, after boring, need not tool changing and can realize attacking the system screw thread, the operation of disperseing is rationally concentrated, shorten the operation number, simplified flow process, save the clamping tool change time, reduced the number of special purpose machine tool and special fixture, shorten production line, simplified the equipment design, improved production efficiency; And bore the structure attack one and also guaranteed the precision of its processing, thereby guaranteed product quality.
Claims (2)
1. a brill is attacked the one combined tap and drill, comprises shank and blade, it is characterized in that described blade is made of the drill bit of its end and the screw tap of close shank.
2. brill according to claim 1 is attacked the one combined tap and drill, it is characterized in that described drill bit and screw tap are made of along the same spiral slot that it axially is provided with blade.
