Circle a is individually fixed in Telescopic joint rod 13, and the grinding wheel c is fixed with auxiliary extracting member b with one end of circular shaft 12 on the contrary, described two
A Telescopic joint rod 13 is respectively cooperating with there are five grinding wheel c, and the circular shaft 12 is double-layer structure, and wherein internal layer is solid axes body
122, and activity is combined with pressure spring 121 respectively in the outer end two sides of axes body 122, which uses sealed construction, institute
Sanding body 1 is stated to form with the fan-shaped disk activity of four equivalent structures.
The grinding wheel slot 11 is divided into the quartering, and interstitial site between any two is equipped with Telescopic joint rod 13.
It is mounted on chuck 2 in a sector disk joined together by two Telescopic joint rods 13, the chuck 2 and grinding wheel slot
11 match.
The inside of the grinding wheel slot 11 is equipped with grinding wheel c, and the notch through grinding wheel c is equipped in the grinding wheel slot 11.
The Telescopic joint rod 13 idler wheel machinery with two telescopic shaft 13a is formed by connecting, wherein one end of telescopic shaft 13a
Weld together with limiting retainer ring a, and the other end is engaged on the outside of pressure spring 121 by semicircle buckle ear 13b.
It include to draw ear b1 and lock shaft b2 in the auxiliary extracting member b, the drawing ear b1 forms inverted T-shaped structure, wherein
The horizontal straight end of ear b1 is drawn to be threadedly engaged with lock shaft b2.
The lock shaft b2 contacts fixation with grinding wheel c.
The working principle of the gear grinding device in above-mentioned technical proposal is explained as follows below:
The present invention is mostly installed on grinding machine bed, mainly manufactures gear technique, due on middle and small scale gear grinding machines
Substantially it is not equipped with special tooth mesh device, grinding wheel can only be manually operated by operator in work and pass through range estimation judgement close to workpiece
It is circumferentially positioned to carry out workpiece, is based on this, mainly disposes gear in sanding body 1 of the invention, when gear is placed and is interior, gear
Axle center matches with circular shaft 12, and due to the double-layer structure design that circular shaft 12 uses, the axle center of gear touches outer layer with propulsion
Continuous compression press spring 121, and the angle between the Telescopic joint rod 13 that pressure spring 121 is fixed constantly becomes smaller, to form one
A V-shape, the sector disk for indirectly promoting Telescopic joint rod 13 to be connected and grinding wheel c are directly contacted in gear tooth slot, work as sand
When wheel c and gear are enough to coincide, with deepening continuously for propulsion, circular shaft 12 can be in rotational structure, if not coincideing, circular shaft
12 just must not rotate, and operator can easily judge that preliminary grinding wheel c and gear tooth slot can not coincide at this time, and operator just needs to make
It adjusts out；
If so, circular shaft 12 can deepen continuously and be constantly in rotation, then then illustrate gear and grinding wheel c when circular shaft 12 gos deep into
Circumferentially positioned completion, when completing circumferentially positioned, the main metamorphosis by Telescopic joint rod 13 is to grinding wheel c and sector disk
The flank surplus with gear is constantly inwardly reduced in movement in the same direction, can not only calibrate the circumferentially positioned of gear tooth slot automatically while may be used also
Unanimously with flank surplus, processing efficiency and spoilage are improved, that is, solves the defect being positioned manually and reduces machinery positioning band
The cost problem come.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this
The range of invention is indicated by the appended claims rather than the foregoing description, it is intended that the equivalent requirements of the claims will be fallen in
All changes in meaning and scope are included within the present invention.It should not treat any reference in the claims as limitation institute
The claim being related to.
