Description

The coiling machine transmission mechanism

Technical field

The utility model relates to a kind of coiling machine transmission mechanism, refer to a kind of line sending that makes coiling machine especially and change line running alone respectively, and have that fuselage is light and handy, assembling and all reducible coiling machine transmission mechanism of manufacturing cost.

Background technology

Coiling machine is a kind of processing machine that spring wire bending is shaped, and it can be in order to part such as shaping spring or with wire forming processing ornaments; Announce No. 5363681 patent case as United States Patent (USP), its announcement has a kind of coiling machine to utilize first servo motor and second servo motor to cooperate the transmission of attached toothed belt, to make spring wire simultaneously produce rotation, one side is pushed ahead, and then spring wire is processed into required finished product, and use this coiling machine to drive the function of spring wire rotation, not only can reduce using and furnishing of same tool, shunt the time with minimizing, in addition via changeing line and line sending carrying out simultaneously, can modulate highly difficult spring, reduce purchasing and the manufacturing of mould of associated machines, reach the benefit that cost is in time asked; Especially with the making of highly difficult spring finished product, the spring finished product manufacturer that usually allows general nothing change the line board hangs back, the commentaries on classics line function of coiling machine also therefore reduced competitiveness and lost huge business opportunity, so certainly will become the important indispensable trend of following coiling machine.

Just, in the above-mentioned existing coiling machine, because its first and second servo motor is to do transmission by attached toothed belt, so need to drive with the bigger motor of transmission torsion, torsion because of its first and second servo motor is bigger again, so directly magnitude range is also more extensive for the line of the spring wire that this coiling machine can be processed, there is no the big or small suitable machine in certain line footpath in the therefore feasible at present common coiling machine; Yet, in case when coiling machine must use the bigger motor of transmission torsion, relative that this coiling machine overall volume is obviously increased was many, and makes its fuselage comparatively heavy; Moreover, the general goods that shape with coiling machine, the line footpath of its employed spring wire often is no more than 2mm, therefore, with regard to present coiling machine, need not assemble the bigger motor of transmission torsion in fact, increases unnecessary cost burden.

In addition, for generally aiming at the manufacturer that makes the spring wire finished product, when the buying coiling machine, often also must look the finished product demand of self producing and choose the machine of suitable production, but if there is no the difference of the scope of application with the present coiling machine of being sold, only with machine extensive use line footpath of all sizes, so not only make manufacturer when buying, have no selectivity, and its coiling machine of buying not only the price height non-again specially for the finished product of oneself production is suitable for, so and be not inconsistent consideration on the cost.

Above-mentioned existing coiling machine is in the running of line sending and commentaries on classics line, it is a kind of transmission mechanism of interlock, so it is first years old, the quite complicated and easy care not of the connection relationship at two servo motors and each position of coiling machine, and when changeing the line action, produce main line sending action, must control the counter-rotating of its first servo motor and can prevent that just spring wire from going out, be difficult for having accurately when the commentaries on classics line of this coiling machine and line sending operate simultaneously again " Synchronization Control ", be easy to generate the unstability of wire rod, and then the ratio that causes defective work to increase.

So as from the foregoing, above-mentioned existing coiling machine not only design at the spring wire of certain line footpath size, and the inconvenience on the function and the existence of scarce line are arranged obviously on its transmission mechanism, so can remain further improvement.

Summary of the invention

Main purpose of the present utility model, provide a kind of coiling machine transmission mechanism, make the line sending of coiling machine can distinguish running alone with the commentaries on classics line, simultaneously still program-controlled and cooperatively interact, to simplify the transmission mechanism of coiling machine, make its easy maintenance, and can make it program control more simple, promptly need not consider to change line and the offset of line sending in running, to reduce the probability that defective products produces.

Another purpose of the present utility model, be to provide a kind of coiling machine transmission mechanism, it not only can use the line sending motor of the less servo motor of torsion as coiling machine, to reduce its overall volume, and this line sending motor is located on the rotating disk of coiling machine, and is made this line sending motor line sending case direct and coiling machine do transmission, so, can make the fuselage of coiling machine comparatively light and handy, and assembling and manufacturing cost all can reduce.

In order to realize above-mentioned purpose, the utility model provides a kind of coiling machine transmission mechanism, comprising:

One rotating disk has one first end face and one second end face, and is provided with a driving shaft that runs through this first end face and second end face with eccentric manner, and this driving shaft is provided with a gear in this end that protrudes first end face;

One line sending case, be fixedly arranged on second end face of above-mentioned rotating disk, this line sending case inside is provided with the conical gear that a breast wheel, a spur gear and two are meshed, the one conical gear is located on this end that driving shaft protrudes second end face, another conical gear is then coaxial with breast wheel, and this breast wheel is meshed with spur gear again, is provided with two rollers in a side of this line sending case in addition, and the one roller is coaxial with this spur gear;

One line sending motor is positioned on first end face of above-mentioned rotating disk, and the rotating shaft of this line sending motor is provided with a gear, and this gear is nibbled mutually with the gear of driving shaft; And

One changes the line motor, be one can make the motor of positive and negative 180 degree rotations, and transmission one is placed on the driving belt on the above-mentioned rotating disk periphery.

Aforesaid coiling machine transmission mechanism has additional a plurality of rollers on one side of described line sending case, and establishes plural spur gear in addition and make interlock with an idle pulley between per two spur gears.

The beneficial effects of the utility model are, can improve existing coiling machine to do transmission and must adopt the defective of the bigger motor of transmission torsion as the line sending motor with attached toothed belt, simultaneously, the utility model coiling machine transmission mechanism is located at design on the rotating disk with this line sending motor, also help coiling machine alleviating on overall volume, and assembling and manufacturing cost all can reduce, and the comparatively inexpensive special-purpose machine of manufacturer that aims at the finished product of making spring wire is provided; The more important thing is, the commentaries on classics line motor of the utility model coiling machine transmission mechanism is to produce rotation in order to this rotating disk of transmission, the line sending motor then pushes spring wire in order to the roller that drives this line sending case and advances, so both are respectively for operating alone and still can cooperatively interacting, thereby make transmission mechanism comparatively simplify and be easy to maintenance, while can make program control more simple, promptly need not consider to change line and the offset of line sending in running, to reduce the ratio that defective products produces.
