Fig. 3 is the two-way multi-rib grinding grinding wheel structure schematic diagram of the present invention.
Specific embodiment
The present invention provides a kind of single-threaded unidirectional multi-rib grinding emery wheel and two-way multi-rib grinding emery wheel.
Unidirectional multi-rib grinding emery wheel in Fig. 2, wherein D swords are to correct thread crest for grinding to repair top sword；Below
Have successively grinding sword 1, grinding sword 2 ..., grinding sword i ... as auxiliary sword is ground, before being processed for thread forming, remove stock removal；
And sword n is ground as the main sword of emery wheel, for the final molding of thread grinding.
L in Fig. 2DTo repair top the distance between sword and emery wheel gyration central axis, LiIt is turned round for i-th of grinding sword with emery wheel
The distance between central axis；Li+1-LiThe amount of feeding of sword is ground for i+1, wherein 1≤i≤n-1.
The mode L uniformly fed may be employedi+1-LiFor J/ (n-1)；Or by the way of non-homogeneous feeding, such as with
The increase L of ii+1-LiIt is linear to reduce, preferably Li+1-LiLess than 3J/ (n-1)；Stepped feeding mode, i≤n/2 also can be used
When, Li+1-LiMore than J/ (n-1)；n/2<During i≤4n/5, Li+1-LiLess than J/ (n-1)；i>During 4n/5, Li+1-LiLess than J/2 (n-
1)。
, can be as needed when carrying out thread grinding processing using the emery wheel in Fig. 2, quantity and the grinding of grinding sword are set
Sword and the numerical value for repairing top sword so that LDFor the required size of thread crest, LnThe ruler needed for the final forming face tooth bottom of screw thread
It is very little, so pass through once unidirectional processing, you can complete the processing and forming of screw thread.It avoids single line emery wheel and feeds repeatedly and cause
Alignment error, improve grinding efficiency.The radial height for repairing top sword is less than 15% height of thread.
It is two-way multi-rib grinding emery wheel in Fig. 3, wherein D1 and D2 are to repair top sword, are to correct ridge for grinding
Top；Have successively below grinding sword 1, grinding sword 2 ..., grinding sword i ..., grinding sword 2n+1, wherein pair with (n+1)th grinding sword
Face is referred to as interface, and the grinding sword of the right and left is symmetrical, and sword n+1 is as the main sword of wheel grinding for grinding, for thread grinding
Final molding；It is the auxiliary sword of abrasive grinding wheel that sword 1, which is ground, to grinding sword n and grinding sword n+2 to grinding sword 2n+1, for thread forming
Before, remove stock removal.When the one side of emery wheel is worn, it could alternatively be opposite side and be processed, reduce grinding wheel shaping
Number improves processing efficiency.
L in Fig. 3D1To repair the radial height of top sword, LiFor the radial height of i-th of grinding sword；Li+1-LiIt is ground for i+1
Cut the amount of feeding of sword.So by once unidirectional processing, the processing and forming of screw thread can be completed, improves processing efficiency.
Structure shown in Fig. 3 is bidirectional grinding emery wheel, when the grinding sword on the left side has abrasion, can replace abrasive grinding wheel
Installation direction, adjustment use repairing from top sword D2, grinding sword 2n+1 is repaiied to the grinding sword progress emery wheel being ground between sword n+1
Shape after the wheel grinding sword of both sides is worn, carries out the correction of the flank shape of emery wheel.It so can further improve processing efficiency.
The grinding sword of the right and left can also use asymmetric distribution, and the total feed amount of both sides is identical, but the mode of substep
Difference for unlike material or different processing requests, can select the amount of feeding using which side.
The grinding sword of the right and left can also use different total feed amounts, process the workpiece of two kinds of specifications, reduce sand
The specification and quantity of wheel reduce emery wheel quantity in stock.
The above is only the optimal specific embodiment of the present invention, but protection scope of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.
The content not being described in detail in description of the invention belongs to the known technology of professional and technical personnel in the field.
