According to the rotary structure provided by the utility, as the angle encoder is mounted below the rotary shaft of the bed body lower body and is connected with the rotary shaft through a coupler, the rotary angle of the upper body can be read accurately; when different conical surfaces are grinded, the bed body can rotate to a required angle accurately through the angle encoder, as a result, various conical surfaces can be effectively grinded accurately, moreover, the rotary structure is convenient to mount and adjust, and reasonable in structure, and the taper precision and the surface precision of a grinded workpiece are high.
Description
Technical field
The utility model relates to a kind of lathe bed angle of revolution location structure, relates in particular to a kind of lathe bed revolution orientation angle structure of large-sized numerical control grinding machine.
Background technology
At present, no matter be domestic external, on all kinds of large-sized numerical control grinding machines, the workpiece of grinding strip tapering, a kind of method adopts two-axle interlocking exactly, and the poor benefit mode of numerical control is carried out grinding, though like this can grinding, surface accuracy is poor; Also have a kind of method by trimmer, emery wheel to be formed to finishing exactly, repair the angle the same with grinding workpiece, do like this efficiency lower, for the different surface of grinding, often remove to repair emery wheel, extremely inconvenience.
Summary of the invention
The purpose of this utility model is poor in order to overcome existing large-sized numerical control grinding machine band tapering workpiece accuracy, operation inconvenience, the shortcomings such as efficiency is low, provide a kind of lathe bed rotatable angle, install easy to adjust, more reasonable structure, the lathe bed revolving structure that the workpiece tapering surface accuracy of grinding is more easily guaranteed.
The technical solution of the utility model is: a kind of lathe bed revolving structure, comprise angular encoder, lathe bed upper body, rotating shaft, lathe bed lower body, butterfly spring, handwheel, connecting plate, be characterized in: lathe bed is fixedly connected with rotating shaft on upper body, rotating shaft bottom and lathe bed lower body are rotationally connected, angular encoder is equipped with in rotating shaft lower end, between lathe bed upper body and lathe bed lower body, the butterfly spring for lathe bed off-load is installed, lathe bed upper body connects gear and ball screw assembly, and handwheel by connecting plate.
Between rotating shaft and lathe bed upper body, be connected by lining and adjustment pad.
In lathe bed lower body, bearing holder (housing, cover) is housed, ball bearing is housed in bearing holder (housing, cover), and be rotationally connected by ball bearing and rotating shaft.
Between angular encoder and rotating shaft, be fixedly connected with by shaft coupling.
Butterfly spring is placed between rolling guide seat and pressing plate, and rolling guide seat is connected with lathe bed upper body by unloading sleeve with pressing plate.
The beneficial effects of the utility model are:
Lathe bed of the present utility model is divided into upper and lower body, in the part of upper body, mechanical disk spring is also installed in many places simultaneously, by disk spring, the load of lathe bed is unloaded to power, make lathe bed upper and lower body have some gaps, by the slew gear of lathe bed end face, gear adds ball screw assembly, and drives upper body revolution, and rotating angle shows by angular encoder.Angular encoder is loaded on lathe bed lower body rotating shaft below, connects by shaft coupling, can accurately read the angle value of upper body rotation.In the time of the different conical surface of grinding, by angular encoder, just can accurately forward required angle value to.So just can be accurately, the various conical surfaces of grinding efficiently.
Therefore, the utility model is installed easy to adjust, rational in infrastructure, makes the workpiece tapering surface accuracy of grinding high.
