Abstract
The invention belongs to a machining method, and in particular relates to a numerical control transmission method for a crankshaft follow-up grinder. The method is characterized in that: a rotating shaft is arranged on a fixed guide rail by a numerical control motor at a constant rotating speed; a numerical control machine drives the rotating shaft to rotate; the rotating shaft is provided with an eccentric shaft; the eccentricity of the eccentric shaft is the same as eccentricity R of a crankshaft connecting rod neck; a sleeve seat is sleeved outside the eccentric shaft; the bottom of the sleeve seat is connected with a linear guide rail slide block; the linear guide rail slide block can move on a linear guide rail; and the linear guide rail is arranged on a movable guide rail and is vertical to the motion direction of the movable guide rail. When the rotating shaft rotates, the eccentric shaft eccentrically rotates to drive the sleeve seat to move and finally drive the movable guide rail to do linear motion. When the rotation angle of the rotating shaft is alpha, the motion distance of the movable guide rail is R Sin alpha to meet sine wave motion. The numerical control motor can realize that the machine tool guide rail moves according to sine wave of the technological requirements at the constant rotating speed, and can simultaneously meet the grinding requirements of high precision and high efficiency.

Technical field
The invention belongs to machining methods, specifically is a kind of numerical control transmission method of bent axle follow-up grinder.
Background technology
The follow-up grinder of numerical-control crankshaft connecting rod neck be a kind of be the advanced processing method of benchmark processing connecting rod neck with the trunnion center, there are a variety of forms can realize this technology, wherein have the vertical and two groups of guide rails of level of a kind of usefulness drive emery wheel do with a connecting rod neck apart from be radius circular motion and with the rotation of connecting rod neck synchronously to process the method for connecting rod neck, has programming easily, debug easy advantage, but owing to need efficient in producing, high accuracy processing, vertical and two groups of guide rails of level are made circumference moving interpolation (generally being 1-2 one-period second), satisfy x=Rcos α simultaneously, y=Rsin α, two groups of guide rails will constantly make to become acceleration and deceleration motion when making the circumference moving interpolation, because numerical-control motor its behavioral characteristics when doing to become acceleration and deceleration motion is difficult to satisfy the interpolation precision of submicron order, this lathe can not satisfy the requirement of high efficiency and high accuracy processing simultaneously.
Summary of the invention
The objective of the invention is deficiency, provide scientific and reasonable, simple and convenient, realized that numerical-control motor machine tool guideway under constant rotational speed moves, can satisfy simultaneously the numerical control transmission method of high accuracy and high efficiency bent axle follow-up grinder by technological requirement realization sine wave at above-mentioned technology.
Technical scheme of the present invention is as follows:
A kind of numerical control transmission method of bent axle follow-up grinder, it is characterized in that: numerical-control motor adopts constant rotational speed, one rotating shaft is contained in decides on the guide rail, the rotation of Digit Control Machine Tool driven rotary axle, one eccentric shaft is arranged on the rotating shaft, the eccentric throw of eccentric shaft is identical with crank-shaft link neck eccentric throw R, eccentric shaft is with a block set outward, the block set bottom is connected with a straight line guide rail slide block, the line slideway slide block can move on line slideway, and line slideway is contained on the moving guide rail, and vertical with moving guide rail movement direction, when rotating shaft rotates, eccentric shaft is made eccentric rotary, drive block set and move, and final the drive is moved the guide rail moving linearly, when the rotating shaft rotational angle was α, moving guide rail displacement is sinusoidal wave motion for RSin α satisfies.To decide the rotating speed rotation, dynamic characteristic is a steady straight line to numerical-control motor, can satisfy high accuracy and high-speed requirement simultaneously always in the moving guide rail moving process of the present invention.
The present invention also can adopt another kind of method to realize that numerical-control motor is under constant rotational speed, machine tool guideway is done sinusoidal wave motion, specifically: deciding to adorn an edge cam on the guide rail, cam centre line is parallel with moving guide rail movement direction, drive the cylindrical shape edge cam around its center line rotation by numerical-control motor, on the moving guide rail roller seat is arranged, one roller is arranged on the roller seat, roller abuts against on the edge cam, when rotating, edge cam drives roller and moving guide rail rectilinear motion, moving guide rail is made the rectilinear motion of RSin α when the shape set of edge cam is rotated the α angle for satisfying, and produces sinusoidal wave motion.
Numerical-control motor is always to decide the rotating speed rotation in the moving guide rail moving process of the present invention, dynamic characteristic is a steady straight line, and the realization numerical-control motor realizes that under constant rotational speed machine tool guideway moves, can satisfy high accuracy and high efficiency grinding requirement simultaneously by the sine wave of technological requirement.
