Description
Technical field
The utility model is related to plain grinding processing technique fields, flat more particularly to a kind of internal tooth part end face that size is smaller
The tooling of mill.
Background technology
The smaller accurate internal tooth part end face of some sizes needs to carry out plain grinding polishing, but existing plain grinding is generally one by one
It carries out, not only handling trouble, the efficiency of grinding is also very low, and is difficult to be adjusted for difference part the required accuracy to be ground
Section, narrow scope of application.Therefore, it is necessary to which existing plain grinding machine frame is improved and is optimized.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provide it is a kind of for subtle internal tooth part end face plain grinding processing
Tooling, to improve grinding efficiency.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of subtle internal tooth part plain grinding tooling, including the locating piece that can be fixed on grinding machine, the locating piece upper side
Equipped with the threaded hole that multiple row size differs, it can be screwed into screw rod in the threaded hole, the screw rod top sets that there are one be adapted to therewith
Pinion gear, the interior tooth engagement of the pinion gear and part to be ground, the distance of the lower face of pinion gear to screw tip, which is less than, to be waited for
Grind the height of part；Location nut is additionally provided on screw rod below the pinion gear, location nut outer ring regular hexagon
Inscribed circle diameter is more than the tip diameter of pinion gear, and the lower face of the part to be ground is contacted with the upper side of location nut.
The upper side of the part to be ground to screw tip difference in height according to the size adjusting of part to be ground in 1~10mm
In range.
The locating piece is equipped at least three row threaded holes, and each row threaded hole is same size, the threaded hole of different lines
Size is different.
The depth of the threaded hole is arranged according to its size between the 1/4~1/3 of its spiro rod length being adapted to.
The location nut is contacted with the upper side of locating piece, and a Hexagon hole is equipped in the middle part of the screw tip.
The utility model has the beneficial effects that：By the way that multiple parts to be ground of same size are located in multiple pinion gears
On, pinion gear is screwed on the screw rod for being located in a row threaded hole, and pinion gear enables part standard to be ground with engaging for part to be ground
Determine position, and handling are very convenient, are vertically put into, remove；When grinding, grinding machine drives locating piece to move back and forth, and completes one
The grinding for arranging part upper surface to be ground, by the positioning of location nut, may be implemented difference and wait grinding to improve the efficiency of grinding
Its scope of application is widened in the adjusting of part the required accuracy.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the overlooking structure diagram of locating piece in the utility model；
Fig. 2 is the location structure schematic diagram of part to be ground in the utility model；
Fig. 3 is the half sectional view of Fig. 2.
Specific implementation mode
Referring to figs. 1 to 3, a kind of subtle internal tooth part plain grinding tooling, including the locating piece 1 that can be fixed on grinding machine, it is described
1 upper side of locating piece is equipped with the threaded hole 2 that multiple row size differs, and screw rod 3,3 top of the screw rod can be screwed into the threaded hole 2
If there are one the pinion gear 4 being adapted to therewith, the interior tooth engagement of the pinion gear 4 and part 5 to be ground, the lower face of pinion gear 4 is arrived
The distance on 3 top of screw rod is less than the height of part 5 to be ground；It is additionally provided with location nut 6, institute on the screw rod 3 of 4 lower section of the pinion gear
The inscribed circle diameter for stating 6 outer ring regular hexagon of location nut is more than the tip diameter of pinion gear 4, under the part 5 to be ground
End face is contacted with the upper side of location nut 6.By the way that multiple parts 5 to be ground of same size are located in multiple pinion gears 4,
Pinion gear 4 is screwed on the screw rod 3 for being located in a row threaded hole 2, and pinion gear 4 enables part to be ground with engaging for part 5 to be ground
It is accurately positioned, and handling are very convenient, are vertically put into, remove；When grinding, grinding machine drives locating piece 1 to move back and forth, and completes
To improve the efficiency of grinding, by the positioning of location nut 6, difference may be implemented in one grinding for arranging 5 upper surface of part to be ground
The adjusting of 5 the required accuracy of part to be ground, widens its scope of application.
Preferably, the upper side of the part to be ground 5 to the difference in height on 3 top of screw rod according to the size tune of part 5 to be ground
Whole that is, smaller part to be ground 5, difference in height is arranged smaller within the scope of 1~10mm, and larger part to be ground 5, difference in height is set
Set more greatly, the range of 1~10mm is the conclusion obtained through overtesting, and what this range can meet various sizes waits for mill zero
The grinding that part different accuracy requires.
As a further improvement of the above technical scheme, the locating piece 1 is equipped at least three row threaded holes 2, Mei Yilie
Threaded hole 2 is same size, and 2 size of threaded hole of different lines is different.By the setting of the same size of same row, when grinding, is same
The same product to be ground of row positioning, once can be completed the grinding of multiple parts to be ground 5, to improve grinding efficiency.
Further, the depth of the threaded hole 2 according to its size be arranged 3 length of screw rod being adapted to it 1/4~
Between 1/3, this range may insure that screw rod positioning is firm, effectively prevent it from falling off in grinding.
Further, the location nut 6 is contacted with the upper side of locating piece 1, and 3 top middle portion of the screw rod is equipped with six in one
Corner apertures, in order to which screw rod 3 to be threaded into hole 2.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-described embodiment,
As long as it reaches the technique effect of the utility model with any same or similar means, it should all be included in the protection of the utility model
Within the scope of.
