Description
Technical field
The clamping tooling of neck rubbing down is turned the present invention relates to a kind of Large Crankshaft and with the method for its rubbing down.
Background technique
Certain Large Crankshaft, tactical diameter is big, and eccentricity 400mm, shelves of cranking arm out are relatively narrow, turn neck roughness requirements compared with
Height needs rubbing down to can be only achieved requirement, and still large-scale grinding machine is not ground this big size crankshaft.Such as numerical-control crankshaft
Grinding machine and follow-up grinder, grinding method are all restricted due to apparatus factor, the lesser crankshaft of eccentricity are only used for, for this revolution
Diameter and the crankshaft that eccentricity is larger and shelves of cranking arm out are relatively narrow, can not be ground, therefore be badly in need of developing a kind of new method.
Summary of the invention
The purpose of the present invention is be directed to above-mentioned status, it is desirable to provide one kind can be applied to turn round that larger, eccentricity is biggish
Large Crankshaft turns neck rubbing down, and rubbing down method is reliable and stable, high-efficient；The smooth rounding in surface, circularity and straightness are assurable
Achievable Large Crankshaft turns the clamping tooling and rubbing down method of neck rubbing down.
Implementation of the invention are as follows: Large Crankshaft turns the clamping tooling of neck rubbing down, left drive shaft and right transmission shaft one end
For cylindrical body, the other end is rectangular, square end band square groove；The cylindrical end of left drive shaft and right transmission shaft fill in tile mounting base with
In inner hole after connection seat combination, and fastened with attachment bolt；The trunnion at the left and right both ends of crankshaft fills in connection seat under respectively
It is fastened in inner hole after the combination of watt seat and with attachment bolt；Left drive shaft and right biography are filled in cranking arm for the left and right both ends of crankshaft respectively
In the square groove of the square end of moving axis, and fastened with screw；Connection seat is identical as the threaded hole center spacing of lower tile mounting base, connection
Seat upper end, lower end inner hole center away from identical as eccentricity of crankshaft；When clamping Large Crankshaft turns neck, left drive shaft and right transmission shaft
Center and crankshaft to turn neck center concentric.
The clamping tooling of neck rubbing down is turned with Large Crankshaft and with the method for its rubbing down, the specific steps are as follows:
1) entirety hangs on lathe, head of a bed chuck dress to the clamping tooling and crankshaft installed for Large Crankshaft being turned neck rubbing down after the completion
Clamp left drive shaft, the centre bore of top top left drive shaft；The top centre bore for withstanding right transmission shaft of tailstock, makes Left Drive
Axis, right transmission shaft and crankshaft turn neck and lathe spindle is concentric；
2) being rotated by lathe spindle drives left drive shaft, right transmission shaft and crankshaft to rotate together；
3) by polish-grinding grinding wheel clamping to lathe saddle, lathe rotation, knife rest moves back and forth, and the polish-grinding grinding wheel on knife rest is
Rubbing down, rubbing down to necessary requirement can be carried out to the neck that turns of crankshaft.
Present invention can apply to turn round larger, the biggish Large Crankshaft of eccentricity to turn neck rubbing down, rubbing down method is reliable and stable,
It is high-efficient.
The Large Crankshaft crossed through rubbing down of the present invention turns the smooth rounding in neck surface, and circularity and straightness more easily guarantee.
Detailed description of the invention
Fig. 1 is the Large Crankshaft schematic diagram of eccentricity 400mm,
Fig. 2 is that clamping Large Crankshaft of the present invention turns neck state diagram,
Fig. 3 is the A-A of Fig. 2, B-B direction cross-sectional view.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings.
Referring to Fig.1,2,3, left drive shaft 4 and 6 one end of right transmission shaft are cylindrical body, and the other end is rectangular, square end band side
Connected in star；The cylindrical end of left drive shaft 4 and right transmission shaft 6 is filled in the inner hole after tile mounting base 5 is combined with connection seat 8, and with connection
Connecting bolt 7 fastens；The trunnion 1 at the left and right both ends of crankshaft is filled in the inner hole after connection seat 8 is combined with lower tile mounting base 9 respectively and is used in combination
Attachment bolt fastening；The left and right both ends of crankshaft crank arm 2 fill in respectively left drive shaft 4 and right transmission shaft 6 square end it is rectangular recessed
In slot, and fastened with screw 10；Connection seat 8 is identical as the threaded hole center spacing of lower tile mounting base 9,8 upper end of connection seat, lower end inner hole
Center away from identical as eccentricity of crankshaft, be 400mm.
The material of a whole set of tooling is 45# quenched and tempered steel, it is ensured that the rigidity of a whole set of tooling.
The method of the clamping tooling rubbing down of neck rubbing down is turned with Large Crankshaft, the specific steps are as follows:
1) entirety hangs on lathe, 11 chuck of the head of a bed to the clamping tooling and crankshaft installed for Large Crankshaft being turned neck rubbing down after the completion
Clamping lives left drive shaft 4, the centre bore of top top left drive shaft 4, and the top centre bore for withstanding right transmission shaft 6 of tailstock 12 makes
Left drive shaft 4, right transmission shaft 6 and crankshaft turn neck 3 and lathe spindle is concentric (Fig. 2).
2) being rotated by lathe spindle drives left drive shaft 4, right transmission shaft 6 and crankshaft to rotate together.
3) by polish-grinding grinding wheel clamping to lathe saddle, lathe rotation, knife rest moves back and forth, and the polish-grinding grinding wheel on knife rest is
Rubbing down can be carried out to the neck 3 that turns of crankshaft.
Rubbing down is carried out using clamping Large Crankshaft of the present invention and turns neck, the smooth rounding in neck surface is turned, turns roundness and straightness
It mores easily guarantee, high production efficiency.
