Abstract
The utility model discloses a polishing bar with a polishing belt for a deep hole. The polishing bar comprises a core bar, a taper shank capable of being inserted into a taper hole of a vertical drilling spindle is arranged at one end of the core bar, a rectangular slot and a threaded hole are arranged at the other end of the core bar, the polishing belt is arranged in the rectangular slot, and a set screw capable of fixing the polishing belt in the rectangular slot is arranged in the threaded hole. Compared with the prior art, the polishing bar has the advantages of being simple in structure, convenient, skillful in design, safe, reliable, low in production cost, high in polishing efficiency and the like.
Description
Technical field
The utility model relates to a kind of polished rod, particularly a kind of deep hole polished rod with sand belt.
Background technology
At present, general rubber mold is because its profile is larger, quality is large, and the shape chamber is dark, and the surface roughness in shape chamber is little, after process machining, the shape chamber all will adopt manual polishing to reach the roughness requirement, if when adopting manual the polishing, all be the rotation of lathe holding workpiece, hand-held polishing tool polishes, because workpiece is usually larger, high rotating speed can not be arranged, and the strength of staff is limited, efficient is very low in polishing process, do not reach processing request, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical,
Easy to operate, safe and reliable, can greatly improve polishing efficiencyA kind of deep hole polished rod with sand belt, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of deep hole polished rod with sand belt, comprise core bar, end at core bar is provided with the taper shank that can insert the vertical drilling spindle taper hole, the other end at core bar is provided with rectangular groove and screwed hole, in rectangular groove, sand belt is installed, in screwed hole, is provided with the holding screw that sand belt can be fixed in the rectangular groove.
Owing to having adopted technique scheme, when using the deep hole polished rod, at first sand belt is contained in the rectangular groove of opening, holds out against with holding screw, deep hole polished rod assembly is installed in the spindle taper hole of upright drill, with clamping workpiece on the workbench of upright drill, the hole and the alignment of shafts that polish align, and sand belt are wrapped on the core bar slowly to insert in the hole again, start lathe, main shaft is moved up and down, and the centrifugal force that utilizes sand belt to produce when rotated polishes; Compared with prior art, the utility model not only has advantage simple in structure, easy to use, and designs ingenious, safe and reliable, low cost of manufacture, the polishing efficiency advantages of higher.

Description of reference numerals: 1-core bar, 2-taper shank, the rectangular groove of 3-, 4-screwed hole, 5-sand belt, 6-holding screw, 7-rubber mold.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind of deep hole polished rod with sand belt, shown in Fig. 1～3, comprise core bar 1, end at core bar 1 is provided with the taper shank 2 that can insert the vertical drilling spindle taper hole, the other end at core bar 1 is provided with rectangular groove 3 and screwed hole 4, in rectangular groove 3, sand belt 5 is installed, in screwed hole 4, is provided with the holding screw 6 that sand belt can be fixed in the rectangular groove 3.
When using the utility model, at first sand belt 5 is contained in the rectangular groove 3 of opening, hold out against with holding screw 6, the taper shank 2 of core bar 1 is installed in the spindle taper hole of upright drill; On the workbench of upright drill, hole and the alignment of shafts that rubber mold 7 will polish align with clamping workpiece; Again sand belt 5 is wrapped on the core bar and slowly inserts in the hole, start lathe, main shaft is moved up and down, the centrifugal force that utilizes sand belt to produce when rotated polishes, the speed of mainshaft is 1200～1600 rev/mins, the utility model not only has advantage simple in structure, easy to use, and designs ingenious, safe and reliable, polishing efficiency advantages of higher.
