Abstract
The invention discloses a non-magnetic penetrating-through type grinder based on a curvature radius of a spherical fiducial surface of a conical roller. The grinder comprises a grinder body part, an grinding wheel frame part, a right guiding wheel part, a left guiding wheel part and a tool part, wherein a grinding wheel is arranged on the grinding wheel frame part; the right guiding wheel part is provided with a right guiding wheel shaft and a driven shaft; a left guiding wheel shaft is arranged on the left guiding wheel part; a left cutter disk seat, a left cutter disk, an isolating disk and a right cutter disk are arranged on the tool part; arc-shaped sliding grooves are formed in the grinder body part, and the grinding wheel frame part slides along the arc-shaped sliding grooves. Through the adoption of the structure, when the spherical fiducial surface of the conical roller is grinded, the continuous adjustability of the curvature radius is realized, the limitation that the isolating disk is used for grinding the spherical fiducial surface of the conical roller, of which the curvature radius is the same as the diameter of the isolating disk is changed, when the spherical fiducial surface of the conical roller with a large curvature radius is processed, an isolating disk of which the radius is smaller than that of the conical roller can be selected, the problems of poor rotational rigidity and poor instability when an isolating disk with a large diameter is grinded are solved, and accuracy requirements for the scattering difference of the grinded spherical fiducial surface of the conical roller and the circular run-out of an end surface are met.
Description
Technical field
The invention belongs to grinding special equipment technical field, particularly relate to a kind of based on spherical base surface of tapered roller radius of curvature without magnetic penetration type grinding machine.
Background technology
At present, the grinding machine of grinding spherical base surface of tapered roller mainly contains three kinds of versions, and one has magnetic penetration type structure, and one is without magnetic penetration type structure, and another is simple grain model accepted way of doing sth structure.Find in production practices, adopt the roller ball basal plane having the grinding machine of magnetic penetration type, the fluctuation of its Circular Run-out Tolerance is large, stock removal is little, when processing the taper roller of larger radius of curvature, be difficult to meet existing technological requirement, and grinding roller belts is out magnetic, follow-up demagnetization operation also to be increased.Adopt tradition without the roller ball basal plane of the grinding machine of magnetic penetration type, the scattered error of its radius of curvature is large, particularly evident when processing the taper roller of larger radius of curvature.And the lathe of two kinds of forms is when processing the roller of certain curvature radius, needs the separator large with its respective diameters, that is, process the roller of much radius of curvature, just need how large diameter separator.As long as the diameter of separator is certain conversely speaking, the radius of curvature of processing is just substantially certain, and the radius of curvature of roller can not adjust, and causing cannot with the as far as possible little separator of diameter, the taper roller that grinding diameter dimension may be large.And adopt the efficiency of the ball cardinal plane grinding machine grinding of simple grain model accepted way of doing sth structure low.
According to innovative point input keyword of the present invention, carry out retrieval type calculating, also do not find that the grinding carriage that innovative point of the present invention proposes moves adjustment by arc chute, make the continuously adjustable document of the angle of the center line of left guide wheel shaft and right guide wheel shaft and emery wheel axis.
Summary of the invention
The object of the invention is can not continuous setup, ball basal plane curvature scattered error is large, Circular Run-out Tolerance fluctuation is large and grinding efficiency is low technical problem in order to solve ball basal plane radius of curvature that existing grinding spherical base surface of tapered roller technology exists.
The object of the invention is to be achieved through the following technical solutions, this grinding machine comprises lathe bed portion, grinding carriage portion, right guide wheel portion, left guide wheel portion, frock portion; Described grinding carriage portion is provided with emery wheel, and right guide wheel portion is provided with right guide wheel shaft, driven axle; Left guide wheel portion is provided with left guide wheel shaft; Frock portion is provided with left cutter chuck holder adapted, left cutterhead, separator, right cutterhead; Described emery wheel is fixed in the arc chute in lathe bed portion by grinding carriage portion, left cutterhead is positioned at left cutter chuck holder adapted, and left cutter chuck holder adapted is fixed on the left guide wheel shaft of lathe, and separator is fixed on one end of driven axle, the other end and the right guide wheel shaft of driven axle are fixed, and right cutterhead is fixed on right guide wheel shaft; Described lathe bed portion is provided with the chute of arc, described grinding carriage portion arcuately slide.
Described grinding carriage moves adjustment by arc chute, makes the center line of left guide wheel shaft and right guide wheel shaft and the angle continuously adjustabe of emery wheel axis.
Wherein left guide wheel shaft is rotated by a servo principal axis driven by motor, and driven together the left cutterhead in left cutter chuck holder adapted to rotate, its rotary speed is stepless adjustable; Right guide wheel shaft is rotated by an other servo principal axis driven by motor, with and driven right cutterhead to rotate, rotary speed is same stepless adjustable, and separator is fixed on the driven axle that is connected with right guide wheel shaft, and its rotating speed is decided by the speed discrepancy of left and right guide wheel.The roller of grinding is wanted to do revolution motion under the guiding of separator, simultaneously, left and right cutterhead is by the contrary left and right guide wheel driven rotary of direction of rotation, the taper roller contacted with left and right cutterhead outer ring raceway is under the promotion of their frictional force, do rotation movement around its center line, during by wheel grinding district, achieve taper roller without magnetic through feed grinding.The rotation that whole grinding carriage can do wide-angle by arc chute regulates, make the center line of left and right guide wheel and the angle continuously adjustabe of emery wheel axis, achieve grinding spherical base surface of tapered roller radius continuously adjustabe on the device, reach the frock with minor diameter, the spherical base surface of tapered roller of processing larger radius of curvature.
Beneficial effect of the present invention: when grinding spherical base surface of tapered roller, achieve radius of curvature continuously adjustabe, change the limitation of the roller ball basal plane by the much radius of curvature of how large diameter separator grinding, when processing the roller ball basal plane of larger radius of curvature, the separator less than its radius can be selected, revolution poor rigidity when solving the grinding of major diameter separator and unstability, make the scattered error of the spherical base surface of tapered roller after grinding and Circular Run-out Tolerance reach required precision.
