Background technology
At present, the strand limit machine that the disclosed textile industry of prior art is used, particularly screw thread twists the limit machine, its structure generally comprises holder, fork, the perpendicular connecting rod that refers to, long connecting rod and the brachydactylia connecting rod of referring to, holder is provided with drive motors, the output shaft of drive motors is by transmission mechanism and fork, long connecting rod and the brachydactylia connecting rod of referring to flexibly connects, also be provided with the perpendicular connecting rod that refers on the fork, drive by drive motors and transmission mechanism, but the long three-dimensional arc spiral motion that refers on connecting rod and the brachydactylia connecting rod implementation space, perpendicular refer to that connecting rod then spurs lines and does and swing back and forth, machine is with the long connecting rod that refers to, brachydactylia connecting rod and the perpendicular strand limit effect that refers to the interoperation realization cloth of connecting rod.Yet, the screw thread strand limit machine of this mechanism, also have following 2 weak points in actual use: one, this transmission mechanism are generally the multi-stage gear transmission or the chain drive of external toothing, and centre part is more, the assembling trouble, the transmission noise is bigger, between the part wearing and tearing severe, long or when running up when machine service time, its transmission accuracy is subjected to restricting greatly, and the strand limit effect of cloth can not be guaranteed; Its two because machine adopts the gear drive or the chain drive of external toothing, for reaching a stable drive ratio, its structural volume is bigger, has limited actual installation and use, has also influenced the good looking appearance of complete machine.Therefore, existing screw thread strand limit machine, its transmission accuracy is low, and volume is big, is unfavorable for actual popularization.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of transmission accuracy height, volume little screw thread strand limit machine.
Goal of the invention of the present utility model is achieved in that a kind of screw thread strand limit machine, comprise holder, fork, the perpendicular connecting rod that refers to, long connecting rod and the brachydactylia connecting rod of referring to, holder is provided with drive motors, the output shaft of drive motors is by transmission mechanism and fork, long connecting rod and the brachydactylia connecting rod of referring to flexibly connects, the end of fork flexibly connects with the perpendicular connecting rod that refers to, perpendicular refer to connecting rod and flexibly connect and can rotate around tie point with holder, length refers to be provided with the fixed bar that is used for fixing both between connecting rod and the brachydactylia connecting rod, the perpendicular finger, be provided with position guiding rod and connecting rod between connecting rod front end and the fixed bar successively, it is characterized in that: described transmission mechanism comprises eccentric wheel and the external gear of being located in turn on the drive motors output shaft, eccentric wheel and fork flexibly connect, and holder is provided with the internal gear that matches with external gear and have the end axle.
The end axle of described internal gear is provided with the displacement axle.
Described displacement axle is provided with and is used for fixing the long mount pad that refers to connecting rod and brachydactylia connecting rod, is connected for bearing between mount pad and the displacement axle.
Be connected for bearing between described internal gear and the holder.
The utility model improves the screw thread strand limit machine of prior art, the transmission mechanism that replaces existing external gear engagement or chain with the transmission mechanism of external gear and internal gear formation, inside and outside gear meshing transmission, parts depreciation is little, the transmission noise is little, the transmission accuracy height has effectively prolonged service life of machine, and the strand limit of cloth is effective; And the part of transmission mechanism is less, has reduced the overall volume of machine greatly, installs easily, and easy to use, machine shape is attractive in appearance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, screw thread strand of the present utility model limit machine comprises holder 1, and holder 1 is provided with drive motors 6, and drive motors 6 is generally the stepper motor of tape program control, is provided with transmission mechanism at drive motors 6 outputs.For solving low, the bulky shortcoming of existing strand limit machine transmission accuracy, the transmission mechanism of the utility model strand limit machine comprises eccentric wheel 10 and the external gear of being located in turn on drive motors 6 output shafts 11, external gear 11 is located at the output the tip of the axis, on holder 1, be provided with the internal gear that matches with external gear 11, be connected for bearing between internal gear 12 and the holder 1, be provided with end axle outside an end face of internal gear 12, the end axle is provided with displacement axle 13, is connected for key between end axle and the displacement axle 13.The outer circumference surface of eccentric wheel 10 is provided with fork 2, for flexibly connecting, generally is connected to good with bearing between fork 2 and the eccentric wheel 10.The end of fork 2 is connected with the perpendicular connecting rod 3 that refers to, perpendicularly refers to connecting rod 3 and flexibly connect and can rotate around tie point with holder 1 that the perpendicular finger tip of connecting rod 3 that refers to is equipped with the rolling curve circle usually, under the driving of eccentric wheel 10 and fork 2, perpendicularly refers to that connecting rod 3 can spur lines and do and swing back and forth.Displacement axle 13 outsides are provided with to be respectively applied for installs the long mount pad 14 that refers to connecting rod 4 and brachydactylia connecting rod 5, and long 5 on connecting rod 4 and the brachydactylia connecting rod of referring to is fixed on the mount pad 14 with screw, and is connected for bearing between mount pad 14 and the displacement axle 13.Length refers to be provided with the fixed bar 7 that is used for fixing both between connecting rod 4 and the brachydactylia connecting rod 5, and fixed bar 7 is connected with the perpendicular end of connecting rod 3 that refers to position guiding rod 8 by connecting rod 9 successively.In the machine operation of strand limit, long connecting rod 4 and the brachydactylia connecting rod 5 of referring to moves by the drive realization flat thread shape of internal gear 12 and displacement axle 13, simultaneously also by the perpendicular drive that refers to connecting rod 3, position guiding rod 8 and connecting rod 9, the three-dimensional arc spiral motion of final realization, the long screw that refers to connecting rod 4 and brachydactylia connecting rod 5 and perpendicularly refer to the swinging back and forth to the pulling of warp, parallel of connecting rod 3 makes the final strand limit effect that realizes cloth of machine.Screw thread strand of the present utility model limit machine meshes as transmission mechanism with external gear 11 and internal gear 12, the little transmission accuracy height of parts depreciation, and the strand limit of cloth is effective; And overall volume is little, installs easily, and easy to use, machine shape is attractive in appearance.
