Description
Technical field
The utility model belongs to and the matching used functional part of surface grinding machine, is especially mainly used in the grinding attachment technical field of structures of the high-precision grinding processing of major diameter part (as spacer, packing ring etc.) both ends of the surface.
Technical background
In traditional plain grinding processing, because the width of emery wheel is limited, in the time that major diameter part is carried out to grinding, because working (finishing) area is large, its processing stroke is long, along with the wearing and tearing of emery wheel, make the stock removal of successively processing of surface of the work inconsistent, thereby reduce the precision of workpiece grinding.And processing parts discontinuity, easily produces machining deformation, flatness, the depth of parallelism and the dimensional accuracy etc. of surface of the work all can be greatly affected.
Summary of the invention
The purpose of this utility model provides a kind of in the time that major diameter part is carried out to grinding in order to overcome the defect of above-mentioned prior art existence just, can make processing parts stressed evenly, reduce the machining deformation of part, guarantee the precisive plane grinding attachment of workpiece grinding accuracy.
The purpose of this utility model is achieved by the following technical solution.
A kind of precisive plane grinding attachment, comprises power section and working portion, and power section is made up of motor, the drive pulley that is connected on motor shaft; Working portion by main shaft, be fixed on driven pulley on main shaft hypomere, be set on main shaft and be positioned at the sleeve on driven pulley and be arranged at the rear end cap of sleeve bottom, the permanent magnetic chuck that is arranged on main shaft head end forms, wherein, sleeve is placed on base and by the upper taper roll bearing that is arranged on top section and connects with collar bush with the lower taper roll bearing that is arranged on stage casing, be arranged with rebound at main shaft head end, permanent magnetic chuck is connected on rebound; Between rebound and the top of sleeve, be provided with ring flange; At the bottom of main shaft, section has been attacked screw thread and has been locked driven pulley by locking nut; The motor shaft of power section is parallel with the main shaft of working portion and be vertically installed on respectively on base.
The utility model can make processing parts, and especially large-scale processing parts is stressed in the time of grinding evenly reduces the distortion of processing parts, guarantees the precision of workpiece grinding.
Accompanying drawing explanation
Fig. 1 is the utility model structure cross-sectional schematic.
The specific embodiment
See Fig. 1, a kind of precisive plane grinding attachment, comprises power section and working portion, and power section is made up of motor 11, the drive pulley 12 that is connected on motor shaft.Working portion is by main shaft 1, be fixed on the driven pulley 3 on main shaft hypomere, be set on main shaft and be positioned at the sleeve 6 on driven pulley and be arranged at the rear end cap 4 of sleeve bottom, the permanent magnetic chuck 10 that is arranged on main shaft head end forms, wherein, sleeve 6 is placed on base 14 and by the upper taper roll bearing 7 that is arranged on top section and connects with main shaft 1 cover with the lower taper roll bearing 5 that is arranged on stage casing, be arranged with rebound 9 at main shaft head end, permanent magnetic chuck 10 is connected on rebound 9, between rebound 9 and the top of sleeve 6, be provided with ring flange 8, attack screw thread and locked driven pulley 3 by locking nut 2 in 1 end of main shaft section.Rear end cap 4 is arranged between sleeve 6 and driven pulley, plays the effect of taper roll bearing 5 under capping.The motor shaft of power section is parallel with the main shaft of working portion and be vertically installed on respectively on base 14.Between motor 11 and base, support chip 13 can be set.
As shown in Figure 1, the utility model, for major diameter part (spacer, adjustment packing ring etc.) Accurate surface grinding, can support the use with the surface grinding machine of disposable type, completes the high-precision grinding to part.Add and man-hour the utility model is directly fixed on Grinder bench and is used, the part of grinding to be placed on revolution permanent magnetic chuck and suck, adopt driven by motor sucker to rotate, just can carry out grinding to workpiece.When work, main shaft 1, rebound 9 and permanent magnetic chuck 10 are Integral synchronous rotation.When the utility model work, rotatablely move by increasing by one to part to be processed, while making processing parts, the stock removal of grinding end face is consistent, so just guaranteed its dimensional accuracy, grind stressed evenly, reduce the machining deformation of part, this is guaranteed the geometrical and toleranging of part, thereby significantly improve the machining accuracy of part, this shows particularly evident in the processing of major diameter part, its two sides depth of parallelism≤0.003mm.This practical new construction compact overall structure, easy to use and maintenance.
