Description
Technical field
The utility model relates to a kind of mechanical actuation device, and is especially a kind of for the reciprocating drive unit of grinding.
Background technology
At present, several modes below common employing the in the reciprocating driving on surface grinding machine or slideway grinder: 1, hydraulic jack drives.2, rack-and-pinion drives.3, ballscrew nut fitting drives.4, the steel cable tractive drives.Above-mentioned several mode has his some characteristics in the use with not enough, is particularly moving back and forth stroke above more than 5 meters, and problem is just more outstanding.
Once, hydraulic jack drive, the length of the long required oil cylinder of movement travel and piston rod is long, difficulty of processing is big.Also need the special fueller of a cover.Hydraulic pressure is in long-term use, and difficulty is avoided oil leakage phenomenon, in case leakage of oil will cause certain pollution to environment.Simultaneously pressure oil uses the regular hour and will change, change oil and once all want 4,5,000 yuan cost.
Two, rack-and-pinion drives.This type of drive is optimum to long stroke.But drive as grinding, when speed surpasses speed more than 10 meters/minute, be easy to produce vibration, the quality of grinding is had certain influence, so use few.
Three, ballscrew nut fitting drives.This drive form by servomotor drive ballscrew nut fitting is the most frequently used type of drive of present Digit Control Machine Tool.The transmission efficiency height.The kinematic accuracy height.But the grinding machine as long stroke drives the some shortcomings that just show him.When screw mandrel length surpasses more than 5 meters.Certain sag of chain just appears in the middle of behind the screw mandrel two supports.One works as the screw mandrel rotating speed above producing vibration more than the 500r/min, and this vibration will have influence on the easy motion of workbench, namely is the screw mandrel that adopts big helical pitch.Workbench reciprocating speed stably all is difficult to reach the above movement velocity of 10m/min.Therefore, also few in the application of the grinding machine of long stroke.
Four, steel cable tractive: use to some extent on this mechanism slideway grinder in early days.This mechanism generally is by the motor-driven wire wheel.Utilize the rotating of control steel wheel to drive the reciprocating motion of workbench, this drive form has the long steel wire rope simultaneously of movement travel, and to have that certain absorbing uses for grinding be proper.But this actuation movement ratio of precision is lower, and the driving mechanism volume is bigger, and inconvenience is installed, and also is of little use at present.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of novel grinding reciprocating drive unit, and its structure adopts the structure of steel cable tractive and feed screw nut pair, therefore has advantages such as precision height, cost is low, damping property is good.
The utility model solves the technical scheme that its technical problem adopts: this for the reciprocating drive unit of grinding, comprise the workbench that is installed on the slide rail, under the workbench drive unit is installed, drive unit comprises the Zola's rope that is connected on the workbench, right stay cord, the below of workbench is provided with the movable pulley that is installed on the guide rail, is respectively equipped with left fixed pulley, left stiff end, right fixed pulley and right stiff end at the left and right directions of movable pulley; Wherein Zola's rope is walked around left fixed pulley, movable pulley successively and is connected on the left stiff end, and wherein right stay cord is walked around right fixed pulley, movable pulley successively and is connected on the right stiff end; Wherein movable pulley is connected on the feed screw nut pair, and feed screw nut pair is connected with servomotor.The driven by servomotor screw mandrel rotates, and drives the movable pulley slip, and movable pulley drives stay cord and also draws the workbench reciprocating motion, and this reciprocator integrates the advantage of steel cable tractive and the advantage that ballscrew nut fitting drives.
Wherein an end of feed screw nut pair is connected with shaft coupling, and shaft coupling is connected with servomotor by transition axis.Because servomotor is bigger, be installed in the centre position inconvenience of drive unit, need fluting or headspace, therefore connect by transition axis, servomotor is installed in the end, be convenient to servomotor and install.
Wherein the outer end of transition axis is provided with synchromesh gear, and wherein servomotor is by the synchromesh gear of band connection synchronously.Play decelerating effect like this, simple in structure.
Wherein movable pulley also can be connected on the hydraulic jack.Adopt the hydraulic-driven movable pulley in this structure, have good stable, and cooperate with pull rope mechanism, shortened the length of hydraulic jack.
Wherein Zola's rope is connected on the right-hand member of workbench, and wherein right stay cord is connected on the left end of workbench.Can shorten the structure length of drive unit like this, namely shorten the distance between left fixed pulley and the right fixed pulley, make overall structure compact and reasonable more.
The effect that the utility model is useful is: the utility model reasonable in design, integrate the advantage of steel cable tractive and the advantage that ballscrew nut fitting drives, and have the following advantages: the length that 1, can shorten the spin screw mandrel.2, because the feed screw nut directly drives working table movement but by the steel cable tractive, the steel cable tractive has certain absorbing effect, the vibration of screw mandrel can directly not have influence on the workbench.3, the motion of movable pulley is to be driven the transmission efficiency height by the feed screw nut.4, servomotor directly drives movable pulley and moves back and forth characteristics such as have the positional precision height, control is convenient.Therefore, this type of drive has the using value of excellent popularization in the reciprocating motion executing agency of long stroke.
