The grinding fixture of wheel bearing bore, while corresponding application method is provided, to improve the quality of cycloidal reducer product.
In order to achieve the above object, the grinding fixture of cycloid wheel bearing bore of the present invention includes the pedestal of lower hollow, described
The flexible sheet of fixing buckle lid on pedestal, the hollow part of the pedestal is equipped with drop-down cylinder, the tension of the drop-down cylinder
Bar presses the upper face center in flexible sheet by briquetting；There are six segmentation circular-arcs to constitute ring for the flexible sheet upper surface tool
The spigot edge of shape, the spigot edge are respectively embedded into circle spacing uniformly distributed three plane claws and three outer circle clamping jaw bottom surfaces
It is connected in the arc groove of matching, forms petal-shaped clamp structure；The upper surface of the plane claw supports Cycloidal Wheel to be ground,
The outer circle clamping jaw has the Inner arc matched with cycloidal gear teeth tip circle outer diameter pine to be ground, and upper surface middle part be equipped with it is to be ground
The profiling positioning tooth that Cycloidal Wheel matches.
In use, carrying out as follows：
The pedestal of cycloid wheel bearing bore grinding fixture is fixed on grinding equipment work platform by the first step；
Second step, that Cycloidal Wheel to be ground is placed on to plane claw upper surface is in place, with outer circle clamping jaw Inner arc and cycloid
The outside circle loose fit centralized positioning of wheel and angular positioning is engaged with profiling positioning tooth；
Third step, manipulation drop-down cylinder drop-down flexible sheet center, upper end is generated by positioning convex platform connection outer circle clamping jaw
The necking deformation of mouth Inner arc, centering clamp Cycloidal Wheel；
4th step starts grinding equipment, completes the precision grinding process in required hole；
5th step, release drop-down cylinder, make flexible sheet and outer circle pawl return, unclamp Cycloidal Wheel；
6th step removes the Cycloidal Wheel for completing hole grinding, clears up tooling.
The present invention effectively increases positioning accuracy, existing various avoiding grinding in pairs although single-piece is ground
Drawback, while significantly improve grinding quality, due also to clamping is very easy, (dismounting of double-disk will compress by hand, the time
It is long), therefore efficiency is improved instead, machining accuracy consistency is got well than traditional pairs of biplate is ground also.
Further, the tie rod upper external screw thread of the drop-down cylinder is equipped with the locking screw being located in briquetting medial recess
It is female.
Further, the medium pore that boss penetrates elastic sheet is stretched under the briquetting.
Further, the radial expansion edge lower surface on the boss is pressed in the upper surface of flexible sheet.
Further, the circumferential edges of the elastic sheet are towards lower convexity.
Further, the upper surface middle part of the outer circle clamping jaw has the recess for being embedded in profiling positioning tooth.
Further, the support portion that the plane claw and outer circle clamping jaw pass through inclined wall and top by the mounting portion of bottom
It constitutes whole.
