Abstract

The utility model relates to a novel reaming and plane drill bit, comprising a drill bit (1), a white steel knife (2), a positioning bolt (3) and a positioning ring (4), wherein an open groove is formed in the upper end of the drill bit (1); a trapezoidal notch and a chip discharge groove are formed in the white steel knife (2); the white steel knife (2) is placed in the open groove of the drill bit (1); and the positioning ring (4) is sleeved on the outer layer of the drill bit (1). The novel reaming and plane drill bit can finish reaming operation and plane operation simultaneously at one step, can realize flatness and smoothness of orifice edges of pipe parts and has the advantage of high work efficiency.

Description

A kind of novel reaming plane drill bit

Technical field

The utility model relates to a kind of drill bit, relates in particular to a kind of reaming plane drill bit.

Background technology

At present, in the processing of pipe part, often relate to reaming and plane two procedures, and the common method that adopts is that pipe part is placed on the drilling machine, earlier with drill bit it is carried out reaming, reaming is finished after again with pipe part from the drilling machine taking-up then descend the plane operation one.Because each procedure all is independently to finish, and so not only greatly reduces the working (machining) efficiency of pipe part, has also increased working strength of workers.

Summary of the invention

Deficiency at above-mentioned technical background exists the utility model proposes a kind of reaming plane drill bit, can realize reaming and plane operations simultaneously by a procedure, and is simple to operate rapid.

The utility model is achieved by the following technical solutions: a kind of novel reaming plane drill bit, and by drill bit 1, white steel knife 2, bolt 3 and locating ring 4 are formed.Upper end at drill bit 1 is provided with open slot, and simultaneously white steel knife 2 is provided with trapezoidal cut and chip area, and white steel knife 2 places in the open slot of drill bit 1, and the skin of drill bit 1 is with locating ring 4.When the cutter head of white steel knife 2 is adjusted to suitable position in open slot, can be by bolt 3 fixing white steel knives 2.

The beneficial effects of the utility model are: because white steel knife 2 is fixed in the open slot of drill bit 1, when carrying out reaming, white steel knife 2 can be simultaneously to the mouth of pipe edge of the pipe part of reaming carrying out plane treatment, both reached the purpose of pipe part reaming, can realize the smooth smooth of mouth of pipe edge again, and white steel knife 2 can in time be discharged in chip area cut the chip that gets off from pipe part, has significantly improved the working (machining) efficiency of pipe part.

Fig. 1 is the utility model overall structure schematic diagram.

Among the figure, 1-drill bit, the white steel knife of 2-, 3-bolt, 4-locating ring.

Fig. 2 is the structural representation of drill bit.

Fig. 3 is the structural representation of white steel knife.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model is by drill bit 1, white steel knife 2, and bolt 3 and locating ring 4 are formed.Before the use, according to the needs of the pipe part reaming degree of depth, the cutter head of white steel knife 2 is adjusted to suitable position in open slot, by locating ring 4 and bolt 3 fixing white steel knives 2.The end of the drill bit 1 adjusted is fixed on the drilling machine, and clamps pretreated pipe part at drilling machine.Open drilling machine, by applying certain amount of feeding for drill bit 1, pipe part is carried out ream operation, when the EDGE CONTACT of the white steel knife 2 on the drill bit 1 and pipe part, at this moment, continue to apply the amount of feeding, the relative reaming degree of depth of pipe part remains unchanged, and white steel knife 2 begins the edge of pipe part is carried out plane operations, and will in time discharge by chip area from the chip of pipe part cutting, efficient orderly assurance the twice manufacturing procedure of pipe part is disposable here finishes smoothly.This drill bit has not only been realized the reaming requirement of pipe part, has guaranteed that also the mouth of pipe of pipe part is smooth smooth.

Claims (1)

1. novel reaming plane drill bit, by drill bit (1), white steel knife (2), bolt (3), locating ring (4) is formed, and it is characterized in that: described drill bit (1) upper end is provided with open slot, and white steel knife (2) is provided with trapezoidal cut and chip area, white steel knife (2) places in the open slot of drill bit (1), and the skin of drill bit (1) is with locating ring (4).
