Description

A kind of aluminium alloy wheel hub inside and outside circle processing monoblock type composite cutter

Technical field

The utility model relates to wheel hub processing technique fields, and in particular to the production of Motorcycle Aluminum Alloy wheel hub.

Background technique

In aluminium alloy wheel hub machining processes, need to use borer 01 (as shown in Figure 1) and right angle cutter 02 (such as Shown in Fig. 2), two cutters are acted by tool changing, process respective position respectively.

If product structure is complicated and changeable, the cutter for needing to use is at two or more, and the Cutting tool installation manner position on numerically controlled lathe It is equipped with limit, needs replacing different cutters to meet the needs of production, in this way, production efficiency certainly will be influenced.

Utility model content

The technical issues of the utility model is solved: the efficiency of product inside and outside circle processing is improved.

In order to solve the above technical problems, the utility model provides the following technical solutions: a kind of aluminium alloy wheel hub inside and outside circle adds Work monoblock type composite cutter, including knife bar and the blade being mounted on knife bar, the end of knife bar is equipped with a mounting plane, the blade Quantity be two, two blades are mounted on the mounting plane, and two blades are located at the two sides of knife bar end center.

Above-mentioned technical proposal is optimized by a knife bar using the structure at its original point of a knife back side, and according to The suitable length of product restructuring and diameter increase a cutting tips (i.e. blade) at its point of a knife back side, make it at one In work step, it is provided simultaneously with the processing method of two kinds of inside and outside circles, in this way, can be reduced frequent tool changing band while enhancing tool strength The process time waste come, realizes one two kinds of functions of cutter, improves the utilization rate of machining apparatus.

Specific embodiment

Such as Fig. 3, a kind of aluminium alloy wheel hub inside and outside circle processing monoblock type composite cutter, including knife bar and the knife being mounted on knife bar Piece, the end of knife bar are equipped with a mounting plane, and the quantity of the blade is two, and two blades are mounted on the mounting plane On, two blades are located at the two sides of knife bar end center.Compared with the prior art, the design increases a blade installation site, The intensity of knife bar can be enhanced.

In conjunction with Fig. 3 to Fig. 5, the knife bar includes knife handle 10 and cutter head 20.The latter half 24 of cutter head is circle, cutter head The top half of first half is a gap 21, and the lower half portion of the first half of cutter head is the half elliptic that outer diameter becomes larger 22, the front end of cutter head is directed toward in the direction that half elliptic outer diameter becomes larger.The first half of cutter head is arranged in the mounting plane Lower half portion on, the mounting plane and the gap form a step 23.The top half of the first half of cutter head is slitted Mouth 21 designs, and provides space for product chip removal.The design of the half elliptic 22 of the lower half portion of the first half of cutter head, Neng Gouti The intensity of high cutter entirety, furthermore, it is possible to increase the chip space of product.

In conjunction with Fig. 3 to Fig. 5, the outer diameter of the knife handle 10 is greater than the outer diameter of the latter half 24 of the cutter head.Along knife bar Axial, the minimum outer diameter of the latter half 24 of cutter head is designed in this way, under the premise of not influencing knife bar integral strength, convenient for producing Product chip removal.

Such as Fig. 3, two blades are respectively hole boring cutter 30 and right angle knife 40.

In conjunction with Fig. 3, Fig. 4, two blades are directly installed on the mounting plane, alternatively, two blades pass through edge bearing 50 It is mounted on the mounting plane.As the optimization design in structure, such as Fig. 6, cutter groove 51 and cutter groove binding groove are opened up on edge bearing Mouth 52, cutter groove are connected to cutter groove fastening notch, and a fastening thread hole 53 passes perpendicularly through cutter groove fastening notch, the fastening thread hole In be bolted with clamp screw, tighten the clamp screw, the width of cutter groove fastening notch is compressed, in turn, cutter groove 51 Width is compressed, and cutter groove is clamped and installed in the blade in cutter groove.The design of cutter groove can also prevent convenient for positioning when blade installation Blade is fallen when disassembly.

Composite cutter described in the utility model is mounted on numerically controlled lathe, the inside and outside circle knot for processing on aluminium alloy wheel hub Structure.Work in-process, it is convenient to omit the forward and back knife and tool changing program needed because of the replacement of working position, only by program The processing at two positions can be completed in adjustment blade number.

The above content is only the better embodiment of the utility model, for those of ordinary skill in the art, according to this The thought of utility model, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be understood For limitations of the present invention.
