Abstract

The servo drive mechanism for a flat joint machine comprises: a feed bar (1), a feed lifting cam (2), a pin shaft (3), a socket base (4), a feeding connecting rod (5), a feeding cam (6), a upper shaft (12) drove by a servo motor (11), a lower shaft (14) in platform (18) drove by a rotary-shuttle servo motor (10), and feed lifting shaft (13) drove by a feed lifting servo motor (9). This invention uses two or three servo motors to drive opposite shafts, eliminates a bevel gear structure or an engagement gear structure to reduce assembly difficulty and cost.

Description

The servo-actuating device of Sewing machines
Technical field:
The invention belongs to sewing machine technique, particularly the servo-actuating device of flat seam machine
Background technology:
Traditional Sewing machines, particularly in the flat seam machine, be used for the cephalomotor axle of going up of driving needle and generally driven by clutch motor, by the transmission of bevel gear transmission mechanism, the lower shaft that is used to drive the rotating shuttle action passes through meshed transmission gear by feed lifting rock shaft to the feed lifting rock shaft that is used to drive the feed dog action by last axle.Because Sewing machines belongs to the high accuracy assembling, the accuracy of gear is had relatively high expectations, adding needs a vertical pivot hole to come the support teeth wheel shaft to realize the connection and the motion of bevel gear on the casing, cause part processing and assembly difficulty big, have influence on Sewing machines complete machine moment and noiseproof feature, and complex structure, production cost is higher.
Summary of the invention:
The objective of the invention is to design a kind of servo-actuating device that utilizes two or three servomotors to drive axle on the Sewing machines, lower shaft or/and feed lifting rock shaft respectively, to omit the bevel gear drive mechanism, even the meshed transmission gear structure between omission lower shaft and the feed lifting rock shaft, reduce assembly difficulty.
The servo-actuating device of Sewing machines of the present invention, comprise retainer, tooth lifting cam, bearing pin, block set, feeding connecting rod, feeding cam, axle is by driven by servomotor on the flat seam machine, it is characterized in that being positioned at the lower shaft of pedestal by the rotating shuttle driven by servomotor, feed lifting rock shaft is by lifting the tooth driven by servomotor, or feed lifting rock shaft is by lifting the tooth driven by servomotor, and feed lifting rock shaft and lower shaft are by gear drive.
Above-mentioned feed lifting rock shaft right-hand member is equipped with feeding cam and fixes with holding screw, and this feeding cam connects feed spool and drives this feed spool by the feeding connecting rod does swing, drives the retainer that the lower end is sleeved on the feed spool left end then and seesaws; The left end of feed lifting rock shaft is equipped with tooth lifting cam, and this tooth lifting cam connects retainer upper end drive retainer and moves up and down.
The feed lifting rock shaft gear is housed on the above-mentioned feed lifting rock shaft, and lower shaft is equipped with lower shaft gear, both engagements.
The present invention since utilize two or three servomotors drive respectively on the flat seam machine axle, lower shaft or/with feed lifting rock shaft, omitted the bevel gear drive mechanism between last axle and the feed lifting rock shaft, or further omit meshed transmission gear structure between lower shaft and the feed lifting rock shaft, simple in structure, part processing is easy, reduce assembly difficulty, reduced production cost.

The specific embodiment:
With reference to Fig. 1, Fig. 2, the upward axle 13 of flat seam machine is directly driven by servomotor 12 and rotates; Feed lifting rock shaft 14 is directly driven by servomotor 11 in addition and rotates.It is fixing that feed lifting rock shaft 14 right-hand members are equipped with feeding cam 6 usefulness holding screws 9, feed spool 16 two ends respectively are with block set 4 and fixing by holding screw 10, the upper end of feeding connecting rod 5 is connected in feeding cam 6, the lower end is connected in block set 4 by bearing pin 3, makes the rotation of feeding cam 6 drive feed spool 16 by feeding connecting rod 5 and does swing; The left end of feed lifting rock shaft 14 is equipped with tooth lifting cam 2, falcate retainer 1 (as shown in Figure 4) upper end is connected in tooth lifting cam 2, the lower end is connected in the block set 4 that is loaded on feed spool 16 left ends by bearing pin 3, thereby making feed spool 16 swings drive retainer 1 seesaws, the rotation drive retainer 1 of tooth lifting cam 2 is moved up and down, realize that retainer 1 drives feed dog and does the elliptical orbit motion.Feed lifting rock shaft gear 7 is housed on the feed lifting rock shaft 14, and lower shaft 15 correspondence positions that are used to drive rotating shuttle 17 are equipped with lower shaft gear 8, two gears engaged.Change lower shaft gear 8, can realization speed regulate.
As another embodiment, with reference to Fig. 1, Fig. 3, the upward axle 13 of flat seam machine is directly driven by servomotor 12 and rotates; The lower shaft 15 that is positioned at pedestal 18 is driven by rotating shuttle servomotor 19 and rotates, and feed lifting rock shaft 14 directly drives and rotates by lifting tooth servomotor 11 in addition.Servomotor 12 is fixed in the casing, rotating shuttle servomotor 19 and lift tooth servomotor 11 and be fixed in the pedestal 18.The feed dog driving mechanism is identical with previous embodiment.
Control each servomotor synchronous operation by microcomputer chip in the foregoing description.
