Abstract
The utility model discloses a main shaft driving device of a quilter, comprising a crank and an up-and-down coupling bar. The utility model is characterized in that it also comprises a slide bar (9), wherein the crank comprises a upper crank (2) and a lower crank (5), one end of the upper crank (2) is connected with one end of a upper coupling bar (3), one end of the lower crank (5) is connected with one end of a lower coupling bar (7), the other end of the upper coupling bar (3) is connected with one end of the slide bar (9), and the other end of the lower coupling bar (7) is connected with the other end of the slide bar (9). The utility model has the advantages of that no large amplitude of vibration will happen when the working speed is above 700rpm, thereby the quilting effect will not be affected and the quilter can operate reliably.
Description
Technical field
The utility model relates to the quilting mechanical field, belongs to a kind of speed of mainshaft that is applicable to greater than 850 rev/mins main shaft drive mechanism of quilting machine.
Background technology
The spindle drive of tradition quilting machines is a crank and rocker mechanism.The crank pivot all is not less than 600mm usually to the distance of rocking bar oscillation center.Deep groove ball bearing is housed on the crank, oscillating bearing is housed on the rocking bar, connecting rod is the elongate rod of one M16～M20, bigger vibration when machine works speed surpasses 700rpm, just took place greater than 20: 1 in its draw ratio, directly influence the quilting effect, even the situation that machine can't be worked occurs.
Summary of the invention
The purpose of this utility model provides a kind of main shaft drive mechanism of quilting machine that can be applicable to high rotating speed main shaft.
The purpose of this utility model is to realize like this, it comprises crank, goes up lower connecting rod, also comprise slide bar, crank is last crank and lower crank, last crank one end is connected with upper connecting rod one end, lower crank one end is connected with lower connecting rod one end, and the upper connecting rod other end connects slide bar one end, and the lower connecting rod other end connects the slide bar other end.
The utility model is owing to adopt the motion combination of two set of bell cranks slide block mechanisms, and one of them crank is a driving link, and another slide block is a driving link; when machine works speed surpasses 700rpm; bigger vibration can not take place, and influence the quilting effect, guarantee the machine reliably working.
Below in conjunction with accompanying drawing the utility model is further specified.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment
Fig. 2 is the schematic diagram of two extreme positions of crank on the utility model embodiment.
Among the figure: 7 times connecting pins of crank 2 upper connecting rod 3 linear bearings, 4 lower crank 5 synchronous pulleys, 6 lower connecting rods, 8 slide bars, 9 bearing blocks, 10 linear bearings, 11 flat keys, 12 lower link axles 13 on the main shaft 1
Below in conjunction with accompanying drawing the utility model is further specified.
The specific embodiment
With reference to Fig. 1, it comprises crank, upper connecting rod 3, lower connecting rod 7, slide bar 9, crank is last crank 2 and lower crank 5, last crank 2 one ends are connected with upper connecting rod 3 one ends, lower crank 5 one ends are connected with lower connecting rod 7 one ends, upper connecting rod 3 other ends connect slide bar 9 one ends by last connecting pin, and lower connecting rod 7 other ends connect slide bars 9 other ends by following connecting pin 8.Two above-mentioned set of bell cranks slide block mechanisms be arranged in main shaft under, the main shaft 1 that is contained in the bearing block 10 is connected with last crank 2 other ends, the limit of last crank 2 is upper to be horizontal, pivot angle is between 40～50 °, as shown in Figure 2.In order to guarantee machine mechanism stability under the high-speed cruising situation, slide bar 9 other ends pass two linear bearings 4,11 and are connected with lower connecting rod 7 other ends, 4,11 supportings of linear bearing guide effect.Lower crank 5 other ends are connected by the flat key 12 that is contained on the lower link axle 13 with synchronous sprocket wheel 6.Course of action: the main servo motor is with through synchronously synchronous pulley 6 is moved in a circle, do gyration by the flat key 12 drive lower cranks 5 that are contained on the lower link axle 13, by lower connecting rod 7, lower link pin 8, make slide bar 9 on linear bearing 4,11, do rectilinear motion again; After crank 2 on the upper connecting rod 3 makes main shaft obtain the reciprocally swinging of expection.
Claims (3)
