Abstract
A transmission mechanism for realizing straight-line motion of needle boards of a double-crank shaft needle machine is characterized in that left and right eccentric shafts rotating at same speed but in different directions, and left and right crank shafts correspondingly connected with the left and the right eccentric shafts are included; the lower ends of the left and the right eccentric shafts are integrated with left and right arc connecting pairs fixed in connecting racks; left and right needle boards are fixedly mounted on the connecting racks, one end of each arc connecting pair is fixed, and the other end in rotation process center moves linearly, therefore, the connecting racks fixed at the lower ends of the crankshafts and the left and the right needle plates on the connecting racks can conduct the linear motion. The transmission mechanism has the advantages as follows: the present matching manner of a sliding shaft and a shaft sleeve is replaced by the crankshaft-connecting rod mechanism, and the rotation of the eccentric shafts is converted into the linear motion of the needle boards through the crankshaft-connecting rod mechanism, therefore, the oil-leakage problem of the needle machine is solved, the product quality is ensured, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to hyperbolic axonometer thorn eedle plate straight-line motion mechanism, is the rectilinear motion that the rotation of eccentric shaft is converted into the needing machine needle plate by linkage specifically.
Background technology
Require rotating speed more and more higher along with needing machine, old sliding axle is connected the leakage of oil problem with axle sleeve more and more serious, can not adapt to new development need, designing new can realize needle plate high speed, reliable straight-line transmission mechanism has become the problem that the technical staff is paid close attention in the industry.
Summary of the invention
The cover that the purpose of this utility model designs at the problems referred to above just can be realized the straight-line transmission mechanism of hyperbolic axonometer thorn eedle plate, this mechanism is converted into the rectilinear motion of needle plate by the arc auxiliary connection with the eccentric shaft of needing machine master driven by motor, and has guaranteed high speed, the reliability service of needing machine needle plate.
The purpose of this utility model is by following: transmission mechanism of the present utility model comprises with speed, counter-rotational left and right eccentric shaft and the corresponding left and right bent axle that is connected with left and right eccentric shaft, the lower end of left and right bent axle combines with the left and right arc auxiliary connection that is fixed in the link respectively, on link, be fixed with left and right needle plate, arc auxiliary connection one end is fixed, rectilinear motion is done at other end rotation process center, thus realize link that the bent axle lower end connected with and on left and right needle plate do rectilinear motion up and down.
In the utility model, left and right eccentric shaft is connected with left and right bent axle by bearing respectively; Left and right eccentric shaft is driven by the Bevel Gear Transmission reversing arrangement by same power transmission shaft.
Left and right arc auxiliary connection is converted into rectilinear motion up and down with bent axle lower end swing, and auxiliary connection can adopt gear, tooth bar engagement, also can adopt rise as high as the banks, the sheave engagement.
Advantage of the present utility model is: utilize brace and connecting rod framework to substitute existing glide axle and axle sleeve fit system, the rotation of eccentric shaft is converted into the rectilinear motion of needing machine needle plate by toggle, fundamentally solved the leakage of oil problem of needing machine, guarantee product quality, also prolonged the service life of equipment simultaneously.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Among the figure: 1 is the left avertence axle, and 2 is the right avertence axle, and 3 is left bent axle, and 4 is right bent axle, and 5 is left arc auxiliary connection, and 6 is right arc auxiliary connection, and 7 is link, and 8 is left needle plate, and 9 is right needle plate.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in the figure: transmission mechanism of the present utility model comprises with speed, counter-rotational left and right eccentric shaft 1,2 and passes through the coupled left and right bent axle 3,4 of bearing, the lower end of left and right bent axle combines with the left and right arc auxiliary connection 5,6 that is fixed in the link 7 respectively, on link 7, be fixed with left and right needle plate 8,9, arc auxiliary connection one end is fixed, rectilinear motion is done at other end rotation process center, thus realize link 7 that the bent axle lower end connected with and on left and right needle plate 8,9 do rectilinear motion up and down.
Left and right eccentric shaft 1,2 is driven by the Bevel Gear Transmission reversing arrangement by same power transmission shaft.
