Technical field
The utility model relates to vertical internal cylindrical honing machine, especially relates to a kind of main shaft control device of vertical internal cylindrical honing machine.
Background technology
The main shaft of vertical internal cylindrical honing machine also is attended by in rotation and pumps, and the oilstone grinding work piece inwall of its cutter (honing head) forms the spirality machining locus that intersects, and is called cross hatch.The shape of cross hatch, angle and the depth are to the performance of piston tube kind part, especially greasy property, power consumption and the pollutant emission of internal combustion engine (compressor) all have considerable influence, so to the rotation of honing machine spindle with to move back and forth accurate control be the target that the honing machine manufacturing is pursued always.
Domestic state-of-the-art honing machine is still the like product of copying German previous generation Hydraulic servo technology at present, because hydraulic cylinder is still adopted in up-and-down movement, rotatablely move and adopt direct current generator or variable-frequency motor, control accuracy is inadequate, random line can appear in the reticulate pattern that the top gem of a girdle-pendant goes out when commutation, has affected the quality of workpiece.
Summary of the invention
The purpose of this utility model is the defective for the prior art existence, a kind of main shaft control device of vertical internal cylindrical honing machine is provided, this device makes cross hatch become the constant helix of slope under the control of main control computer, avoid traditional honing machine in the random line phenomenon of reticulate pattern that main shaft occurs in the commutation process up and down, guaranteed the quality of grinding work-piece.
For achieving the above object, the utility model can be taked following technical proposals:
The main shaft control device of vertical internal cylindrical honing machine described in the utility model, comprise the frame with longitudinal rail, the main shaft that is driven simultaneously by reciprocating mechanism and rotational motion mechanism rotatablely moves up and down along described guide rail, in the lower end of described main shaft honing head is installed
Described reciprocating mechanism comprises the reciprocating motion servomotor that is arranged on described frame top and by the ball screw assembly, of its driven rotary, connecting rod one end of horizontal set on described ball-screw nut links to each other with described main shaft by bearing, and the other end and described guide rail are slidingly matched;
Described rotational motion mechanism comprise be arranged on the drive sprocket that is driven by reductor by rotating servo motor on the described frame and be sleeved on the described main shaft by movable sprocket, be provided with driving chain at described drive sprocket with between by movable sprocket.
Described reciprocating motion servomotor is electrically connected with the control module of industrial computer through the reciprocating motor driver; Described rotating servo motor is electrically connected with the industrial computer control module through the electric rotating machine driver.
The utility model has the advantage of simple in structurely, realized main shaft rotation and reciprocating accurate control have been guaranteed the crudy of workpiece.The reciprocating motion of main shaft adopts the ball-screw rectilinear motion of driven by servomotor secondary, employing servomotor-reductor-sprocket wheel chain drive rotatablely moves, two motors are controlled according to setting program is unified by a upper industrial control computer (industrial computer), can be according to size and the purposes of honing workpiece, by the main control computer of honing machine according to reticulate pattern and other requirements, when main shaft is commutated back and forth, the rotation acceleration-deceleration, acceleration time, the output torque, the synchronous uniform velocity value that arrives after accelerating, the uniform motion time etc. is accurately controlled, guarantee that cross hatch is the constant helix of slope (workpiece is the constant straight line of slope) when side bus launches, avoided traditional honing machine to form parabolic path in the commutation process up and down at main shaft, be that random line phenomenon appears in honed surface, and reticulate pattern angle and the depth all are in controllable state.Be used for the cylinder barrel honing of internal combustion engine, compressor, can guarantee to obtain good lubrication between piston and cylinder barrel, reduced lubrication oil consumption, reduced pollutant emission, make the various types of compact machine reduce power consumption, internal combustion engine has been saved fuel oil, has improved economy and the power performance of machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2, Fig. 3 are respectively the reticulate pattern schematic diagram of the utility model institute honing workpiece.
The specific embodiment
Shown in 1, the main shaft control device of vertical internal cylindrical honing machine described in the utility model, comprise the frame 2 with longitudinal rail 1, the main shaft 3 that is driven simultaneously by reciprocating mechanism and rotational motion mechanism also rotates when guide rail 1 moves up and down, lower end at main shaft 3 is equipped with honing head 4 by air guide dop 15, honing connecting rod 16
For guaranteeing the accurate control to main shaft, reciprocating mechanism comprises the reciprocating motion servomotor 5 that is arranged on frame top and by the ball screw assembly, 6 of its driven rotary, connecting rod 7 one ends of horizontal set on ball-screw nut link to each other with main shaft 3 by bearing, and the other end and guide rail 1 are slidingly matched;
Rotational motion mechanism comprise be arranged on the drive sprocket 9 that is driven by accurate retarding machine by rotating servo motor 8 on the frame and be sleeved on the main shaft 3 by movable sprocket 10, be provided with driving chain 11 at drive sprocket 9 with between by movable sprocket 10.
Moving back and forth servomotor 5 is electrically connected through the control module of reciprocating motor driver 12 with industrial computer 13; Rotating servo motor 8 is electrically connected with industrial computer 13 control modules through electric rotating machine driver 14; Controlled simultaneously by 13 pairs of two servomotors of industrial computer.
Because honing is short stroke processing, frequent commutation is its principal character, it is asynchronous owing to two kinds of motions when common honing machine honing commutates, can not accelerate simultaneously, can not reach simultaneously setting at the uniform velocity again, so cause random line at grinding face, these random schlierens have been rung conveying and the distribution of lubricating oil in the parts use; Adopt driven by servomotor control can be as accurate as ten thousand/forward 1,000,000 to/turn, and two motors can be under the industrial computer programmed instruction by the accurate synchronization that needs of reticulate pattern, so reticulate pattern is permanent slope.Fig. 2 and Fig. 3 are two kinds of reticulate pattern schematic diagrames that adopt main shaft control device honing workpiece of the present utility model.
