Abstract
The invention discloses a needle bar driven cam connecting shaft assembly of a high-speed computerized embroidery machine, which is composed of a needle bar driven cam connecting shaft and a transmission shaft. The needle bar driven cam connecting shaft assembly has the main technical characteristics that a cam on the needle bar driven cam connecting shaft and the driving connecting shaft are designed into an integral structure; two ends of the driving connecting shaft are respectively provided with an opening boss of the straight line shape; and two ends of the transmission shaft are respectively provided with an opening groove of the straight line shape, wherein the opening groove is matched with the opening boss of the straight line shape on two ends of the driving connecting shaft. Thus, the accuracy on assembling each needle bar driven cam connecting shaft assembly of the high-speed computerized embroidery machine can be guaranteed, the power of the high-speed computerized embroidery machine can be effectively transferred, and the high quality of embroidery can be guaranteed.
Description
Technical field
The present invention relates to a kind of improvement of computerized emboridering machine needle bar driving device, belong to machinery manufacturing technology field.
Background technology
High-speed electronic calculator embroidery machine shank driving cam connecting axle assembly is the vitals of computerized emboridering machine.Traditional computerized emboridering machine shank driving cam connecting axle assembly is made up of cam, driving connecting axle and power transmission shaft three parts, cam and driving connecting axle are split-type structural, the two ends that drive connecting axle interconnect by power transmission shaft, be connected with the drive motors output shaft by jockey then, to reach the purpose of transferring power.In the needle bar drive device of multi-end multi-needle bar high-speed electronic calculator embroidery machine, the shape and the angle of the cam on all computerized emboridering machine shank driving cam connecting axles must keep identical, could guarantee the uniformity that all shanks in the high-speed electronic calculator embroidery move up and down in the course of the work, embroider out high-quality embroidery.Otherwise, not only can influence high-speed electronic calculator embroidery machine production efficiency, and the quality of embroidery also can be suffered serious destruction.And the present common this traditional computerized emboridering machine shank driving cam connecting axle that adopts in the high-speed electronic calculator embroidery machine, because cam and driving shaft are split-type structural, therefore, in assembling process, be difficult to all install each cam in all the shank driving cam connecting axles in the multi-end multi-needle bar high-speed electronic calculator embroidery machine and the angle that drives connecting axle and power transmission shaft very accurate, like this, just brought very big difficulty to the assembly crewman.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of this invention is to provide a kind of rational in infrastructure, assembling is simple and easy, and can guarantee the high-speed electronic calculator embroidery machine shank driving cam connecting axle assembly of assembly quality again.
High-speed electronic calculator embroidery machine shank driving cam connecting axle assembly of the present invention is made of shank driving cam connecting axle and power transmission shaft two parts, its major technique characteristics are that cam on the shank driving cam connecting axle and driving connecting axle are designed to monolithic construction; Two ends driving connecting axle are provided with the opening boss that is the in-line structure; Two ends at power transmission shaft, be provided with and drive the open recess that is the in-line structure that opening boss that the connecting axle two ends are the in-line structure matches, like this, accuracy in the time of just guaranteeing each high-speed electronic calculator embroidery machine shank driving cam connecting axle component assembling, thus the effective transmission of high-speed electronic calculator embroidery machine power and the high-quality of embroidery guaranteed.
Through the present invention after the above-mentioned design, simple and reasonable for structure, assemble simple and easy, because it is designed to monolithic construction with cam and driving connecting axle, and the two ends that will drive connecting axle are designed to a word hatch frame, like this, have not only guaranteed the accuracy of high-speed electronic calculator embroidery machine shank driving cam connecting axle assembling, and simplified assembly process, and alleviated assembler's labour intensity greatly.

The specific embodiment
High-speed electronic calculator embroidery machine shank driving cam connecting axle assembly of the present invention is made of shank driving cam connecting axle 1 and power transmission shaft 2 two parts, its major technique characteristics are that cam on the shank driving cam connecting axle 13 and driving connecting axle 4 are designed to monolithic construction; Two ends driving connecting axle 4 are provided with the opening boss 5 that is the in-line structure; At the two ends of power transmission shaft 2, be provided with and drive the open recess that is the in-line structure 6 that opening boss 5 that connecting axle 4 two ends are the in-line structure matches.Like this, the opening boss 5 that is the in-line structure at driving connecting axle 4 two ends in the high-speed electronic calculator embroidery machine shank driving cam connecting axle assembly, can be connected with the open recess that is the in-line structure 6 that is arranged at power transmission shaft 2 two ends very easily, then, be connected with the output shaft of drive motors by jockey, thereby reach the purpose of transferring power.
The present invention is owing to be designed to monolithic construction with cam 3 and driving connecting axle 1, and the two ends that will drive connecting axle 4 are designed to the in-line hatch frame that matches with power transmission shaft 2, so not only guaranteed the accuracy and the precision of the assembling of high-speed electronic calculator embroidery machine shank driving cam connecting axle, and simplified assembly process greatly, improve efficiency of assembling, and alleviated assembler's labour intensity greatly.
