Abstract
The utility model discloses a ream rod, which comprises a handle part, a diameter changing part, and a guide part that are sequentially connected. The guide part is provided with a knife mounting hole, and the handle part is provided with a pin. The technical scheme is as follows: a beam rod Morse handle and the beam rod are respectively processed; through matching and connecting a ream rod mounting groove on the ream rod Morse handle and the handle part of the ream rod, and connecting the pin arranged at the handle part of the ream rod a pin hole on the ream rod Morse handle, the replacing and the assembling and disassembling are convenient, meanwhile, a positive ream and a negative ream at two end surfaces of the same base hole needs no replacing of knife rods, therefore, the working efficiency is increased. Furthermore, the using of the knife rod for a plurality of base holes under positive ream state or negative ream state is realized, and the material is saved.
Description
Technical field
The utility model relates to a kind of ream bar.
Background technology
The ream truncation of bolt hole end face is at present cut, and usually with the morse shank disjunctor ream bar of being with tang, and can only the upper surface of datum hole be processed, and the lower surface must adopt the clamping mode of changing shank to operate.And need to change together with morse shank according to each datum hole specification, can be described as the different size datum hole, must distinguish different knife bars, wherein the knife bar that forward and reverse ream is cut is distinguished again.Datum hole if any plurality of specifications on the same workpiece needs positive ream or anti-ream, and frock is changed frequent, reduces operating efficiency; And a datum hole adopts a knife bar, the making material of waste frock.
The utility model content
Technical problem to be solved in the utility model provides a kind of ream bar.Change easy to loading and unloadingly, two positive and negative reams of end face of same datum hole need not more changing knife rod, increase work efficiency.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the ream bar, comprise the shank, reducing portion, the guide part that connect successively, and described guide part is provided with the dress tool bore, and described shank is provided with latch.
Described latch and described shank are fixed.
Described latch one end stretches out in the outer surface of described shank.
Described guide part end is provided with tight cutter screw, and described tight cutter screw is communicated with the dress tool bore, so that cutter is adjusted.
The utility model is owing to adopted technique scheme, Counterboring bar morse shank and ream bar are processed respectively, be complementary with the shank of ream bar by the ream bar mounting groove on the Counterboring bar morse shank and be connected, the latch that is provided with by ream bar shank is connected with pin hole on the Counterboring bar morse shank again, make that the replacing of ream bar is easy to loading and unloading, two positive and negative reams of end face of same datum hole need not more changing knife rod, have improved operating efficiency.Simultaneously, can realize the use of a knife bar when positive ream of the datum hole of plurality of specifications or anti-ream, also save material.
Description of drawings
Fig. 1 is the structural representation of the utility model ream bar.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the utility model ream bar, comprise the shank 1, reducing portion 2, the guide part 3 that connect successively, described guide part 3 is provided with dress tool bore 5.Described shank 1 is provided with latch 4.Described latch 4 is fixed with described shank 1.Described latch 4 one ends stretch out in the outer surface of described shank 1.Described guide part 3 ends are provided with tight cutter screw 6, and described tight cutter screw 6 is communicated with dress tool bore 5.Tight cutter screw 6 is in order to adjust cutter tactical diameter (being that ream is cut diameter) back to the cutter tightening.
This ream bar must be used in combination with Counterboring bar morse shank, is all spendable many specifications instrument of positive and negative ream.Determine each size of reducing portion, guide part according to the requirement at processed position, and the size of the latch that shank and shank are provided with keeps suitable with the size of the mounting groove of Counterboring bar morse shank and pin hole respectively, the datum hole size difference at processed position no matter, or, all can reach processing purpose to the positive and negative ream of datum hole both ends of the surface.
