Abstract
A swing type diameter changing mechanism of a spring machine comprises a sliding plate type post rod swing device and a connecting rod flexible swing device, and a hinge pin of the sliding plate type post rod swing device is connected onto a front wall plate of the spring machine. A post rod and a lead screw nut are fixed on a sliding plate of the sliding plate type post rod swing device, and when a lead screw I fixed on a reduction gearbox output shaft rotates, the post rod is driven to advance and retreat. A cylinder body arranged at the rear end of a connecting rod of the connecting rod flexible swing device can slide in an inner wall of a guide sleeve, and when a lead screw II fixed on the reduction gearbox output shaft rotates, the connecting rod can be driven to advance and retreat. The front end of the connecting rod and a slide rest hinge pin are connected, the slide rest is driven by the connecting rod to swing during advancing and retreating of the connecting rod, and the sliding plate and the connecting rod are controlled to advance and retreat respectively by a programmable logic controller. The sliding plate type post rod swing device and the connecting rod flexible swing device can separately swing, accordingly inclination angle of the post rod is changed all along during the moving process, and further the best force application direction to steel wires can be guaranteed. An arc-shaped sliding tenon arranged at the front end of the sliding slide rest and a pressing plate fixed on the front wall plate are matched, and accordingly swing track of the sliding plate type post rod swing device is more accurate.
Description
Technical field
The present invention relates to the swing type diameter changing mechanism of spring winding machinery field, especially coiling machine.
Background technology
Diameter changing mechanism is the prerequisite critical component of wire spring winding machinery, in the spring winding process, steel wire is forced to send, move to a direction, the push rod of diameter changing mechanism or roller must be arranged in several positions and go up from different directions steel wire is pushed, change the direction of advance of steel wire, just can make steel wire coil coiled spring.The various springs of coiling various outer diameter, different rotation directions must be adjusted application of force direction and the force application location of each push rod.So, a kind of mobile reducing mechanism of spring machine has appearred on the domestic market, its essential characteristic is: have a vertical mobile upper slide device to be provided with push rod at front wallboard, below the slide of upper slide device, be provided with again a lower skateboard device that laterally drives, utilize the vertical movement of upper slide and moving horizontally of lower skateboard, push rod can be vacillated on the coiling machine panel change the position.But no matter where vacillate, the angle of inclination of push rod and vertical direction is all fixed, all be thick-and-thin to the application of force direction of steel wire namely also, when push rod is vacillated edge machine extreme position, such as when the upper left corner or the lower right corner, steel wire can break away from the push rod front end groove and with the push rod contacts side surfaces, thus, making precision and stability for spring just can not get due guarantee, thereby is difficult to effective control spring quality.And two groups of skate apparatus of this kind structure are to stack up and down ， Po diameter changing mechanism is increased, and the horizontal thrust transmission link rigidity of lower skateboard descends; The push rod position is along with rising, and it is more to force winding unit to protrude toward the front wallboard outside, greatly reduces rigidity and the stability of winding mechanism, and this defective is particularly outstanding when reeling large and medium-sized spring.A lot of applicants think that use the numerical control new technology of in recent years develop rapidly, machine construction can also be simplified, operating function can also be strengthened, and this case occurs thus.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of shift position of push rod and the swing type diameter changing mechanism that application of force direction is controlled more convenient and flexible coiling machine are provided, push rod in movement changes the angle of inclination with vertical direction at any time, the application of force direction of push rod can dynamically be changed along with the movement of vertical direction, make the push rod axial line aim at all the time the coiling center, allow the groove of push rod front end effectively control the coiling motion of steel wire.
The objective of the invention is to realize by following technical solution.
The swing type diameter changing mechanism of coiling machine is characterized in that: comprise slide type push rod pendulous device and connecting rod telescopic oscillating device; All be provided with bearing pin below the base of every covering device and use the location and be connected on the coiling machine front wallboard, can both be around separately bearing pin rotary oscillation; Described bearing pin comprises slide bearing pin and connecting rod base bearing pin, all is screwed on front wallboard;
