Abstract
The utility model relates to a numerical control step air cylinder comprises a programmable position controller, a stepper motor with small power, an electromagnetic pneumatic reversing valve, a leading screw and nut pair, an air cylinder and a piston anti-rotating mechanism. The programmable position controller of the numerical control step air cylinder can control the electromagnetic pneumatic reversing valve to feed air to the air cylinder, and simultaneously control the stepper motor to rotate to drive the leading screw-nut pair, making a piston do rectilinear motion. The utility model has the advantages of simple structure, low cost and high precision, having the application to the controlling occasion which requires the multipoint positioning of the air cylinder.
Description
The utility model is to be used to finish the digital control of multipoint positioning, belongs to the digital control cylinder in pneumatic transmission and control engineering field.
Digital control cylinder is the new product that grew up in recent years, existing abroad many versions, but its principle is roughly the same, and a position detecting system such as magnetic scale system are promptly arranged; Coarse pitch ball-screw--photoelectric encoder system, its principle of work is to give controller with the cylinder location signal feedback, controller is according to position signalling of setting and feedback signal control air valve, and to the forward and reverse air feed of cylinder, the control brake device is realized braking to cylinder, its bearing accuracy is at ± 0.5～0.1mm, the shortcoming of this principle is a complex structure, technological requirement height, cost costliness, bearing accuracy is subjected to the influence of load and speed bigger, is difficult to improve.
In view of the problem that above-mentioned existing procucts exist, the purpose of this utility model is the numerical control stepping cylinder of a kind of open loop control of design, has simple in structure, with low cost, advantages such as precision is high, practicality.
Numerical control stepping cylinder described in the utility model adopts position able to programme controller control electromagnetic pneumatic reversal valve to the cylinder air feed, control step motor-driven leading screw rotation simultaneously, make the piston that nut is housed under gas pressure, do straight line and move, thereby realize multipoint positioning function.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is numerical control stepping cylinder control system figure;
Fig. 2 is a numerical control stepping cylinder structural drawing;
As shown in Figure 1, 2, the numerical control stepping cylinder mainly is made up of position able to programme controller (1), electromagnetic pneumatic reversal valve (2), stepper motor (3), bearing (4), nut (5), leading screw (6), piston (7), piston rod (8), cylinder barrel (9), piston rod anti-rotation (10), front end end cover (11), rear end cap (12), bearing (13).1 is position able to programme controller input signal, and 0 is the output signal of position able to programme controller.Stepper motor (3) is fixed on the bearing (13) of cylinder barrel (9) rear end, bearing (13) is fixedly connected with rear end cap (12), leading screw (6) is fixedly connected with the axle of stepper motor, is screwed on piston (7) with leading screw (6) nut engaged (5).Be provided with piston rod anti-rotation (10) at cylinder barrel (9) front end.Nut (5) and leading screw (6) have adopted the lead angle of self-locking and non-self-locking state.
Position able to programme controller (1) control electromagnetic pneumatic reversal valve (2) is to cylinder barrel (9) air feed, control step motor (3) drives leading screw (6) rotation simultaneously, make the piston (7) that nut (5) are housed under gas pressure, do corresponding straight line and move, realize multipoint positioning function.
The stepper motor that the utility model adopts is lower powered, by the position able to programme controller that single-chip microcomputer consists of it is realized control, have the functions such as movement velocity, cylinder startup or braking, threads of lead screw gap and accumulated error compensation elimination of adjusting cylinder piston.
The leading screw of the utility model design has rational lead angle, makes piston realize reliably starting and braking in the stepper motor torque range, guarantees that displacement and the stepper motor rotary synchronous of piston carries out, and obtains higher positional precision.
