Abstract
The invention discloses a milling and reaming combined cutter, which comprises a reaming cutter handle and a reaming cutter rod. The reamer comprises a reamer handle, a reamer rod, a conical milling cutter, a key and a cutter head, wherein the reamer handle and the reamer rod form a reamer whole, the conical milling cutter is arranged at the lower part of the reamer handle, the conical angle of the conical milling cutter is 120 degrees, and the conical milling cutter is tightly matched with the reamer handle by virtue of the key. The invention can finish the processing of the upper hole and the lower hole of the gear seat ring mounting hole at one time, thereby ensuring the coaxiality requirement of the upper hole and the lower hole and improving the production efficiency by more than two times.
Description
Technical field
The present invention relates to the machining tool field, relate in particular to a kind of hinge gang tool that mills.
Background technology
Cylinder of diesel engine has covered 8 gear seat ring installing holes, and the hole is a step, and top is that maximum outside diameter is that ф 36, coning angle are 120 ° of taper seats, and the bottom is the hole of ф 10+0.018, and the axiality in hole is not more than 0.02 up and down.Prior art is the hole of hinge ф 10 earlier, uses the hole of 120 ° of taper mill milling ф 36 again.So not only production efficiency is low, and is difficult to guarantee the specification requirement of hole axiality up and down.
Summary of the invention
For addressing the above problem, the present invention provides a kind of hinge gang tool that mills, and two holes about the gear seat ring installing hole of step are processed at one time, and with the axiality requirement in two holes about guaranteeing, and enhances productivity.
For achieving the above object, the present invention realizes through following technical scheme:
A kind of hinge gang tool that mills of the present invention comprises reamer handle, reamer bar.It is whole that described reamer handle and reamer bar constitute reamer, and at the taper mill that install the bottom of reamer handle, the coning angle of taper mill is 120 °, and taper mill becomes tight fit by key with the reamer handle.The hole of reamer bar processing bottom when Machining of Gear seat ring installing hole like this, the conical bore on the taper mill processing top on top reaches and processes at one time.
The invention has the beneficial effects as follows: gear seat ring installing hole processes at one time in two holes up and down, has guaranteed the axiality requirement in two holes up and down, and has enhanced productivity more than two times.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is A-A cutaway view.
The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is further described below, this embodiment only is used to explain the present invention, does not constitute the qualification of protection domain of the present invention.
As depicted in figs. 1 and 2: a kind of hinge gang tool that mills of the present invention comprises reamer handle 1, reamer bar 2.Described reamer handle 1 constitutes reamer integral body, the taper mill 3 that install the bottom of reamer handle 1 with reamer bar 2.The coning angle of said taper mill 3 is 120 °, and taper mill 3 is by 2 one-tenth tight fits of key 4 and reamer handle.Like this when Machining of Gear seat ring installing hole, the hole of reamer bar 2 processing bottoms, the conical bore on taper mill 3 processing tops has realized processing at one time two holes up and down.
After the present invention implements, can guarantee the axiality requirement in two holes up and down of gear seat ring installing hole, and enhance productivity more than two times.
