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), feed lifting shaft gear (7), a upper shaft (13) drove by a servo motor (12), and a feed lifting shaft (14) or lower shaft (15 ) drove by a servo motor (11). This invention eliminates a bevel gear structure to reduce assembly difficulty and manufacture cost.
Description
Technical field:
The invention belongs to sewing machine technique, particularly utilize servomotor to drive the device of flat seam machine running.
Background technology:
The tradition flat seam machine is that the general clutch motor of utilization drives and goes up axle and drive, and the feed lifting rock shaft in pedestal with on spool between utilize the bevel gear transmission.Because Sewing machines belongs to the high accuracy assembling, also high to the bevel gear required precision, adding needs a vertical pivot hole to support vertical pivot 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 are higher.
Summary of the invention:
The objective of the invention is to design a kind of two separately-driven flat seam machine servo drives of servomotor that utilize.
The present invention includes retainer, tooth lifting cam, bearing pin, block set, feeding connecting rod, feeding cam, axle is characterized in that feed lifting rock shaft or lower shaft by another driven by servomotor by driven by servomotor on the flat seam machine, and feed lifting rock shaft and lower shaft are by gear drive.
Above-mentionedly feeding cam is housed and fixes with holding screw by driven by servomotor feed lifting rock shaft right-hand member, 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 feed lifting rock shaft, lower shaft gear is housed on the lower shaft, both engagements.
The present invention has omitted the bevel gear drive mechanism owing to utilize two servomotors to drive on the flat seam machine axle respectively and feed lifting rock shaft rotates, and is simple in structure, part processing is easy, has reduced assembly difficulty, has reduced production cost.

Fig. 7 is the upward view of block set 4 among Fig. 1.
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 3) 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.
Another embodiment, servomotor 11 is coaxial with lower shaft 15, and feed lifting rock shaft 14 and lower shaft 15 are by gear drive.
Control each servomotor synchronous operation by microcomputer chip in the foregoing description.
The foregoing description all can be avoided the drawback brought by the bevel gear transmission mechanism.
