Abstract

The utility model, which discloses, a kind of exempts from tool changing combination cutter for hole in piece part rapid processing, the first drill bit and the second drill bit are respectively arranged in the lower end of drilling rod, and second drill bit diameter less than the first drill bit, be provided with PCD blade in the first drill bit and the second chisel edge.The purpose of this utility model be it is a kind of exempt from tool changing combination cutter for hole in piece part rapid processing, facilitate clamped one time to be processed twice, machining accuracy is higher, and substantially increases production efficiency, reduces processing cost.

Description

It is a kind of to exempt from tool changing combination cutter for hole in piece part rapid processing

Technical field

The utility model belongs to processing equipment field, specially a kind of to exempt from tool changing composite hinge for hole in piece part rapid processing Knife.

Background technique

Reamer is a kind of process tool for bore hole milling inner wall surface, and it is a kind of right to process under normal conditions Answer the hole inner wall of size.As described in Figure 1, one reamer can only generally be processed the corresponding hole D1, processes the hole inner wall of other sizes, It can only tool changing；And even if encountering stepped hole D1, D2 that two kinds of holes are concentric in Fig. 2, it also can only tool changing.

In this way, processing hole D1, D2 shown in Fig. 2, tool change time and tool changing process, brought to production and processing Biggish time waste.And multiple machining benchmark is be easy to cause to dock, it be easy to cause two hole machined rear centerline to offset, adds Work precision reduces.

Summary of the invention

The purpose of this utility model be in view of the above problems, provide it is a kind of for hole in piece part rapid processing to exempt from tool changing compound Reamer, clamped one time are processed twice, and machining accuracy is higher, and substantially increase production efficiency, reduce processing cost.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of to exempt from for hole in piece part rapid processing Tool changing combination cutter is respectively arranged with the first drill bit (2) and the second drill bit (3), and the second drill bit (3) in the lower end of drilling rod (1) Diameter less than the first drill bit (2), be provided with PCD blade (80) in the first drill bit (2) and the second drill bit (3) front end.

Further, cutting edge slot, the cutting edge slot are provided on the side wall of first drill bit (2) and the second drill bit (3) It is arranged along drill bit axial side wall, and the cutting edge slot connection of two drill bits；And first drill bit (2) the first blade (21) be arranged in sword Mouthful slot side, and the second blade (31) of the second drill bit (3) is arranged in cutting edge slot side, PCD blade (80) are separately positioned on the One blade (21), the second blade (31) front end.

Further, first drill bit (2) detachably separates with the second drill bit (3), and the axial end of the first drill bit (2) It is provided on face knife bar set (20), is provided with knife bar head (30) on the end face of corresponding second drill bit (3).

Further, movable block (22) and corresponding spring are provided on the inner sidewall of the knife bar set (20) (23), locking slot (32) corresponding with movable block (22) is provided on the side wall of the knife bar head (30).

The utility model has the beneficial effects that the utility model provide it is a kind of for hole in piece part rapid processing to exempt from tool changing multiple Reamer is closed, clamped one time is processed twice, and machining accuracy is higher, and substantially increases production efficiency, reduces and is processed into This.

1, using two reamers of concentric design, a tool changing clamping realization is processed twice, and only need to once be positioned, and is added Work is more convenient.

2, processing twice is because be ladder hole machined (such as Fig. 2), and the stroke of second of processing is on the basis of first time processing The upper stroke that further increases can be completed, and therefore, the processing used time when used time of Compound Machining than processing respectively twice is shorter, raw It produces more efficient.

3, it using dismountable combination cutter structure, can be exchanged with random combine, to adapt to the requirements of combination of different inner diameters, But combination rule requires internal diameter D1 > D2 in hole to be processed.

Label character described in figure indicates are as follows: 1, drilling rod；2, the first drill bit；21, the first blade；22, movable block；23, bullet Spring；3, the second drill bit；31, the second blade；32, locking slot；80, PCD blade；20, knife bar set；30, knife bar head.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model There is any restriction effect.

As shown in Fig. 2, the specific structure of the utility model are as follows: a kind of to exempt from tool changing composite hinge for hole in piece part rapid processing Knife is respectively arranged with the first drill bit 2 and the second drill bit 3 in the lower end of drilling rod 1, and the diameter of the second drill bit 3 is less than the first drill bit 2, PCD blade 80 is provided in the first drill bit 2 and 3 front end of the second drill bit.

Preferably, cutting edge slot is provided on the side wall of first drill bit 2 and the second drill bit 3, the cutting edge slot is along brill Head axial side wall setting, and the cutting edge slot connection of two drill bits；And first drill bit 2 the setting of the first blade 21 in cutting edge slot side, And second drill bit 3 the second blade 31 be arranged in cutting edge slot side, PCD blade 80 is separately positioned on the first blade 21, the second knife 31 front end of sword.

A kind of preferred mode, as shown in figure 4, first drill bit 2 is detachably separated with the second drill bit 3, and first bores It is provided with knife bar set 20 on first 2 axial end face, is provided with knife bar head 30 on the end face of corresponding second drill bit 3.
