Abstract
The utility model discloses a buffering pneumatic swing arm mechanism on a printer. In the buffering pneumatic swing arm mechanism, a piston rod on a cylinder is in threaded connection with a long shaft through a long nut; a swing arm is provided with an assembling hole which is connected with a point B on the long shaft; reciprocating swing of the swing arm is limited by backers fixed on a frame; a slide block is sleeved on the long shaft, and is coaxial to the swing arm at the point B; a pressure spring is arranged at the upper end of the long shaft slide block, and is limited by using a nut; another pressure spring is arranged at the lower end of the long shaft slide block, and is fixed through a pin by using a nut; and the parameters of the pressure spring are the same as those of the other pressure spring. The buffering pneumatic swing arm mechanism has the effects that a driving swing arm of the cylinder can be buffered, and the buffering strength is adjustable; and moreover, the pairwise pressure springs are adopted, so that the swinging strength and speed of the cylinder working on the swing arm are not influenced.
Description
Technical field:
The utility model relates to the pneumatic oscillating arm mechanisms of a kind of buffering, is specially adapted to use on the sheet-fed press.
Background technology:
Traditional pneumatic and oscillating arm mechanisms, for cylinder directly drives the swing arm swing, the spacing determining positions of swing arm by swing arm both sides backer, its shortcoming is: produces when swing arm contacts with the backer and impacts, loud.
Summary of the invention:
The task of the utility model is that to propose a kind of buffering strength adjustable, does not influence cacheable pneumatic oscillating arm mechanisms on the printing machine of swinging strength and speed.The task of the utility model is to accomplish like this; It comprises that piston rod on the cylinder screws through long nut with major axis and is connected; There is pilot hole spacing by the backer who is fixed on the frame in the swing arm with the reciprocally swinging that major axis B point is connected swing arm; It is characterized in that: it is coaxial at the B point with said swing arm that the slide block sky is enclosed within major axis, and it is spacing with nut that stage clip is contained in the upper end of major axis slide block, and another stage clip is contained in the lower end of major axis slide block and fixes through pin with nut.Said stage clip is identical with each parameter of another stage clip.The utlity model has following effect: the driving oscillating arm mechanisms available buffer of cylinder, and also buffering strength is adjustable, owing to adopted the use of paired stage clip, thus swinging strength and the speed of cylinder operation in swing arm do not influenced.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Drawing explanation: 1, fulcrum, 2, cylinder, 3, long nut, 4, nut, 5, major axis, 6, stage clip, 6-1, stage clip, 7, slide block, 8, pin, 9, the backer, 9-1, backer, 10, swing arm.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, cylinder 2 is fixed on the frame through fulcrum 1, and the piston rod on the cylinder 2 screws with long nut 3 spirals respectively with major axis 5 and is connected; Slide block 7 skies are enclosed within on the major axis 5 coaxial at the B point with swing arm 10, have pilot hole to be connected with major axis B point in the swing arm, and backer 9 and 9-1 are fixed on the frame; Its objective is the swing arm reciprocally swinging spacing; Stage clip 6 is contained on the major axis of upper end of slide block spacing with nut 4, and it is fixing through pin 8 with nut that stage clip 6-1 end is housed on major axis below the slide block, and each parameter of stage clip 6 and 6-1 is identical; If when compress variation is consistent, can produce identical active force.
During work, when cylinder piston rod stretched, driving swing arm through slide block was that swing at the center with the A point, and extreme position is undertaken spacing by the backer.When two stage clip deflections are consistent, can produce identical active force.When stretching out like cylinder piston rod, because slide block is at the overhead cover of major axis, the deflection of two stage clips is identical, is that the force direction of swing arm is opposite to slide block, because two stage clip balance of powers, so do not change swinging strength and the speed of cylinder to swing arm.Reverse stroke is also like this.The buffering of swing arm is at swing arm pendulum during in the limit inferior position, promptly closes on when contact with backer 9, and cylinder has reached stroke terminal at this moment; At this moment swing arm causes stage clip 6-1 decrement greater than stage clip 6 under the inertia force effect, and promptly two stage clips to the force direction of slide block upwards; So swing arm is produced buffering; Swing arm is when the limes superiors position, and stage clip 6 decrements produce the buffering to swing arm simultaneously greater than stage clip 6-1.
The adjustable positions of this mechanism can be regulated buffering strength according to actual operating position, avoids simultaneously because the influence that part's machining errors is brought.Because the fixed-site of nut on major axis through the adjusting to nut, can change stage clip and stage clip total length in the course of the work so.Because backer and backer's fixed-site through the adjusting to long nut, can change the particular location of nut and C point when high-low limit, the relative size of the decrement of stage clip and stage clip when promptly adjusting two limit.Through common adjusting, accomplish the adjusting of the buffering strength of high-low limit position to nut and long nut.
