Description
Technical field
The utility model relates to cutter fields, and in particular to a kind of compound tool for step hole machined.
Background technique
A kind of extension box assembly product needs processing two step bearing holes of processing on main shaft, traditional processing technology need
Boring cutter boring level-one hole is wanted, then changes rose reamer chamfer angle, then change milling cutter spot facing, changes boring cutter boring second hole, then change rose reamer chamfered edge
Angle.Five guarded blade utility knife are needed altogether, and the preparatory process such as tool changing delay, and product processing time is caused to extend, the life of product
Low yield, to increase time cost.
Summary of the invention
Place, the utility model provide a kind of composite cutter for step hole machined in view of the deficiency of the prior art
Tool, simple and easy to get, one completes multinomial processing cutter, eliminates the program of tool changing.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of compound tool for step hole machined, including integrally formed cutter hub and the blade that is set on cutter hub,
It is characterized by: the cutter hub includes in the mounting portion of level Four multi-diameter shaft and the taper shank portion for location and installation, the blade
Including be positioned at mounting portion end the first boring cutter and successively be installed on the mounting portion shaft shoulders at different levels the first rose reamer,
Two boring cutters, the second rose reamer, first boring cutter, the second boring cutter include at least two, and the blade of the second boring cutter is right with it
The shaft shoulder end face answered is parallel, and the mounting portion is additionally provided at least two straight groove structures for running through mounting portion.
Further, the mounting portion is provided with installation position in the corresponding shaft shoulder portion of level Four multi-diameter shaft, first boring cutter,
First rose reamer, the second boring cutter, the second rose reamer are fixed by screws on the cutter hub.
Further, first rose reamer, the blade of the second rose reamer and the angle of the cutter hub axis are 30 °.
Further, the taper in the taper shank portion is 7:24.
The beneficial effects of the utility model, which include: the utility model, permeates much knives tool a cutter, can complete
Multinomial processing content, saves the time, greatly improves processing efficiency, and improves the consistency of product processing quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of compound tool for step hole machined as shown in Figure 1, mainly by integrally formed cutter hub 1 and fixed peace
The blade of dress forms.Cutter hub 1 divides to install the mounting portion of blade and for by the taper shank portion on Cutting tool installation manner to knife rest, wherein
Mounting portion is in the shape of level Four multi-diameter shaft.The end face of mounting portion and the corresponding shaft shoulder position of multi-diameter shaft at different levels are provided with knife
Piece installation position.The first boring cutter 2 is equipped with by screw on the corresponding installation position in the end of mounting portion.First boring cutter 2 includes pair
Claim two diamond shape alloy blades of installation, point of a knife is located at the periphery of corresponding first order Step Shaft.First boring cutter 2 is main
First order hole for boring processing shoulder hole.
The first rose reamer 3 is equipped with by screw on the installation position at the shaft shoulder position of second level multi-diameter shaft, wherein second
The shaft shoulder end face of grade Step Shaft is inclined-plane, and the first rose reamer 3 of corresponding installation is triangle alloy blade, blade and cutter hub
1 axis is in 30 ° of angle installations.First rose reamer 3 is mainly used for the first order hole chamfer angle of stepped hole.
The second boring cutter 4 is equipped with by screw on the installation position at the shaft shoulder position of third level multi-diameter shaft.Youngster's boring cutter 4 wraps
Include two diamond shape alloy blades being symmetrically installed, point of a knife is located at the periphery of corresponding first order Step Shaft, blade with
Its corresponding shaft shoulder end face is parallel.Second boring cutter 4 is mainly used for second level hole and the flat first order of ream of boring processing shoulder hole
The end face of stepped hole.
The second rose reamer 5 is equipped with by screw on the installation position at the shaft shoulder position of fourth stage multi-diameter shaft, wherein the 4th
The shaft shoulder end face of grade Step Shaft is inclined-plane, and the second rose reamer 5 of corresponding installation is triangle alloy blade, blade and cutter hub
1 axis is in 30 ° of angle installations.Second rose reamer 5 is mainly used for the second level hole chamfer angle of stepped hole.Make to adapt to a variety of lathes
It is 7:24 by the taper design in its taper shank portion with the compound tool of the utility model.Meanwhile in order to be applicable in the compound tool
Material ranges are wider, have at least two straight groove structures for running through mounting portion in the mounting portion design of cutter hub 1, keep its chip removal suitable
Freely, intensity is higher.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
