Abstract
The invention relates to an arbitrary adjustment mechanism of a reciprocating motion stroke of a slider. The arbitrary adjustment mechanism comprises an eccentric shaft and a rocking bar which are arranged on a machine body, and an adjusting slider arranged on the rocking bar, wherein the eccentric shaft drives the rocking bar and the adjusting slider to swing by a transmission rod, the adjusting slider drives a working slider to move in a reciprocating manner by a connecting rod, wherein a servo motor drives a screw rod and a guide slider by a worm wheel and gear mechanism to realize working of the adjusting slider on the rocking bar so as to change the reciprocating motion stroke of the slider. The arbitrary adjustment mechanism disclosed by the invention can realize arbitrary adjustment of the reciprocating motion stroke of the slider, is stronger in equipment generality and has the advantage of effectively reducing the equipment investment cost.
Description
Technical field
The present invention relates to punching machine, be specifically related to punching machine and move back and forth any governor motion of ram travel, belong to the punching machine technical field.
Background technology
At present, punching machine all is to lean on the reciprocating motion of slide block to realize the work purpose, wherein, the reciprocating motion of slide block will rotatablely move converted by toggle, the eccentricity of crank of existing punching machine is owing to being changeless all, so, the reciprocating motion stroke of slide block also is changeless, and still, punching machine in the course of the work, sometimes the forcing press that needs different ram travels, for this reason, must use the forcing press of relevant pressure stroke specification, so, there is the relatively poor defective of equipment interoperability, and brings the larger defective of investment cost of equipment.
Summary of the invention
The object of the invention is to: provide a kind of reciprocating motion ram travel any governor motion, this kind mechanism can realize that the reciprocating motion stroke of slide block regulates arbitrarily, makes the versatility of equipment stronger, and can effectively reduce the investment cost of equipment.
Any governor motion of a kind of reciprocating motion ram travel of the present invention, comprise: frame, eccentric shaft, drive link, connecting rod, rocking bar, adjusting slider, adjusting rod, guide runner, thrust bearing, servomotor, screw mandrel, worm gear, the feed screw nut, the work slide block, worm screw, on frame, be mounted with eccentric shaft, the two ends of drive link link to each other actively with an end of rocking bar and the crank throw position of eccentric shaft respectively, an other end of described rocking bar is hinged on above the fuselage actively, an adjusting slider that can be free to slide is set on rocking bar, a guide runner that can be free to slide and work slide block are set on fuselage, the two ends of connecting rod are hinged actively with work slide block and adjusting slider respectively, the two ends of adjusting rod are hinged actively with guide runner and adjusting slider respectively, on guide runner, install and fix a rhizoid thick stick, described leading screw axis is consistent with the movement locus of guide runner, be provided with feed screw nut at leading screw, cylindrical at feed screw nut is installed fixedly worm gear, described worm gear both sides are provided with thrust bearing, form intermeshing drive connection between worm gear and the worm screw, the end of servo motor shaft and worm screw is connected and fixed.
Operation principle of the present invention is: the rotation of eccentric shaft drives the swing of rocking bar by drive link, adjusting slider is passed through in the swing of rocking bar, connecting rod drive work slide block moves reciprocatingly, and the reciprocating motion stroke of work slide block is to be determined by the pendulum radius of adjusting slider, and the pendulum radius of adjusting slider is by its determining positions on rocking bar, so, if change the position of adjusting slider on rocking bar, just can change the reciprocating motion stroke of work slide block thereupon, because servomotor can rotate arbitrarily under the control of program in real time, so, servomotor just drives feed screw nut by worm and gear and does arbitrarily rotation, feed screw nut drives leading screw, leading screw tape guide slide block is mobile arbitrarily, thereby changes the position of adjusting slider on rocking bar.
Beneficial effect: can be found out by fundamental diagram of the present invention and operation principle, the present invention can realize that the reciprocating motion stroke of slide block regulates arbitrarily, makes the versatility of equipment stronger, and can effectively reduce the advantage of the investment cost of equipment.
