Said invention can accurately finish various curved grinding wheels.
Description
Technical field
The present invention relates to a kind of dresser, particularly a kind of cylindrical grinder dresser.
Background technology
Grinding machine is a kind of common machining equipment, except that carrying out also can carrying out the processing of groove, curved surface to workpiece the grinding on surface to workpiece.Grinding machine is when processing work, and emery wheel can wear and tear, so emery wheel must repair emery wheel by dresser after using certain hour, makes emery wheel recapture the form accuracy and the sharpness on surface.The existing dresser that is used for form grinding mainly contains two big classes, one class is the mechanical type dresser, it adopts by the ready made mould the same with processing work is that the diamond moulding is repaired roller or made trimmer finishing pen produce desired movement locus by mechanical mechanism, to repair out the forming grinding wheel that meets the processing work requirement.Another kind of is NC dresser, it controls the finishing pen by application programming or the diamond dressing wheel movement locus comes trimming wheel, but existing these dressers its finishing pen or diamond dressing wheel when trimming wheel can only rely on the workbench of grinding machine to do to move with respect to emery wheel all around, and promptly dressing tool can only be made x with Grinder bench, the y axle moves.These trimmers are when the higher and more steep abrasive wheel forming face of as shown in Figure 1 curved surface of finishing, finishing pen or freeing wheel can interfere with emery wheel near the on the left side end points, at this moment can have a strong impact on dressing accuracy or just can't repair at all, therefore a kind of dresser that can the various complicated forming surface of finishing is provided is the problem that solves by every means for a long time in the industry.
Summary of the invention
The objective of the invention is to overcome the shortcoming that exists in the prior art, a kind of NC dresser that can repair various complicated forming surface is provided.
The present invention is achieved by the following technical solutions: a kind of grinder wheel trimmer, comprise dressing tool, base and digital control system, it is characterized in that: said base is installed on the Grinder bench, be provided with a rotating disk above the base, digital control system control servomotor A drives dial rotation, dressing tool is installed on the rotating disk, the direct trimming wheel of dressing tool, and the circular arc center of circle of its cutting edge is dropped on the rotational axis line of rotating disk.
Described dressing tool is finishing pen or diamond dressing wheel.
Described base has and the parallel plane translot of Grinder bench, is provided with a worm-and-wheel gear in the groove, and worm screw is driven by motor A, the turning cylinder of worm gear and above the base turning cylinder of rotating disk be same rotating shaft.
The rotation of the diamond dressing wheel on the described rotating disk is driven through transmission mechanism by motor B.
Described transmission mechanism is gear drive or belt transmission.
A described finishing nib is made or is cut the cutter head of emery wheel and makes by diamond.
Because fabricator's prodigiosin of the present invention is done all around to move with respect to emery wheel, and can rotate, so the present invention can accurately repair the emery wheel of various curved surfaces around the circular arc center of circle of dressing tool cutting edge, the present invention is simple in structure easy to make in addition, cost is low, the effect height, and numerical control programming is realized easily.

Grinder bench, 5. trimmer base, 6. rotating disk, 7. worm gear, 8. worm screw, 9. motor A, 10. motor B, 11. freeing wheel transmission mechanisms, 12. finishing points, 13. the dial rotation axle, 14. grinder beds, 15. grinder wheel bases, C. freeing wheel is symmetrical in the axis normal plane of freeing wheel, the normal of D. finishing point place emery wheel cross section curve.
The specific embodiment
With reference to Fig. 5,6, trimmer of the present invention constitutes by repairing pen 2 or diamond dressing wheel 3 and base 5, and trimmer base 5 is installed on Grinder bench 4 and can clamps on the workbench of processing work.Grinder bench 4 can move leftwards and rightwards as y on grinder bed 14, and emery wheel base 15 can be made x and move forwards, backwards on grinder bed.Trimmer base 5 tops are provided with a rotating disk 6, and the front end of base promptly offers a groove that is parallel to the Grinder bench plane near emery wheel one end, is provided with worm gear 7 and worm screw 8 in the groove, and worm screw is driven by motor A9.Worm screw 8 drives worm gear and rotates, the turning cylinder 13 of worm gear is the turning cylinder of rotating disk 6, realize that like this rotating disk is by motor A driven rotary, motor A controls rotational angle by digital control system, on the rotating disk clamping device can be installed directly, clamping finishing pen 2 or diamond dressing wheel 3 is installed, is that diamond dressing wheel then must be driven by motor B10 through transmission mechanism as dressing tool.In this trimmer, the circular arc center of circle that is installed in its cutting edge of dressing tool palpus assurance above the rotating disk is dropped on the rotational axis line of rotating disk, when the cutting edge of dressing tool is desirable sharp-pointed state, when the radius that is the cutting edge circular arc was zero, the finishing point 12 that dressing tool contacts with emery wheel directly dropped on the dial rotation axial line.
In the dresser of the present invention, base is installed on the Grinder bench, can be y to motion because of Grinder bench, and simultaneously, the emery wheel base can be x and move forwards, backwards.Therefore trimmer base itself can have been realized doing x, y axle with respect to emery wheel, i.e. motion all around, because of a rotating disk has been installed again on the trimmer base, so dressing tool of this trimmer, promptly finishing pen or diamond dressing wheel in fact relatively wheel face make two shifting axles and a turning cylinder promptly around the three-shaft linkage of Z axle, make the axis of finishing pen or axis normal plane C that freeing wheel is symmetrical in freeing wheel parallel as far as possible with the normal D of finishing point place emery wheel cross section curve, assurance dressing tool and emery wheel do not interfere.Main points of the present invention are the movement locus in the circular arc center of circle of control dressing tool cutting edge, when the cutting edge of dressing tool is desirable sharp-pointed state, when the radius that is the cutting edge circular arc is zero, be the finishing point movement locus that contact with emery wheel of control dressing tool, the floor projection of the movement locus of repairing when just controlling the circular arc center of circle or cutting edge for desirable sharply state must overlap with the floor projection of the movement locus of disk axes line.The worm-and-wheel gear of rotating disk is driven by servomotor A9, when controlling the angle of worm gear rotation by numerical control programming, the rotating disk that is fixed on the worm wheel shaft also correspondingly rotates identical angle, make the normal direction in the axis of finishing pen or the axis normal plane tracking emery wheel cross section that freeing wheel is symmetrical in freeing wheel, when the benefit that dressing tool rotates around the circular arc center of circle of cutting edge is numerical control programming, can not consider to rotate the rotation of moving axis to the influence of two shifting axles, programming realizes easily.
