Abstract
The utility model relates to a driving apparatus for a disc sewing machine, which overcomes the disadvantages of loose structure, poor precision and no adaptation to high-grade fineness sewing of the existing driving apparatus for a disc sewing machine. The driving apparatus of the utility model is provided with three cams on a vertical shaft connected with the motive power output end of the sewing machine, wherein each of the cams drives motion actuating mechanisms through a driving swing stem on the edge of each of the cams and a connecting rod hinged with an uppermost cam, and the motion actuating mechanisms are connected with the driving swing stem and the connecting rod, and a latch needle and a sewing needle which are used for sewing can be matched with each other to work. The disc sewing machine which adopts the driving device of the utility model has compact structure and favorable precision, and can satisfy the requirement of the high-grade fineness sewing.
Description
Technical field
The utility model relates to a kind of braiding robotic suturing device, is a kind of transmission device of disk sewing machine more accurately.
Background technology
The transmission device of sewing machine is the vitals of sewing machine, and whether its structure is reasonable, directly influences the serviceability of sewing machine, the quality and the operating efficiency of stitching.Traditional sewing machine transmission device is to adopt the cam link transmission, shown in Fig. 1 dashed rectangle, drive the vertical movement mechanism and the horicontal motion mechanism of the crochet hook of sewing up usefulness by connecting rod by interior external cam, drive suture needle with the synchronization-moving executing agency of dials by little cam by connecting rod, drive suture needle by eccentric wheel by connecting rod and radially wobble mechanism, make crochet hook and suture needle co-ordination.Interior external cam, little cam and eccentric wheel are not to be contained on the same axis, but be contained in respectively on two transverse axis, and with interior external cam, the connecting rod that little cam is connected with eccentric wheel is the slender axles that expose, whole transmission device is loosely organized, this slender axles very easily because of the vibration of sewing machine disk or in being subjected to the impact of external force be out of shape, thereby influence the precision of sewing machine, in addition, interior external cam, little cam and eccentric wheel be not on same axle, and be long when service time one, when deviation appears in rotating speed, very easily cause crochet hook and the suture needle can not synchronous coordination work, thereby the sewing machine of this transmission device can not adapt to the needs of high-grade meticulous stitching.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above existence, and the transmission device that a kind of compact conformation, precision are good, can adapt to the disk sewing machine of high-grade meticulous stitching needs is provided.
For achieving the above object, sewing machine transmission device of the present utility model, comprise that some cams, cam and crochet hook vertical motion, crochet hook horizontal movement, suture needle radially wobble connecting rod between the mechanism with dials with the transmission fork between each executing agency of moved further and cam and suture needle, above-mentioned cam be positioned at one with vertical shaft that the sewing machine clutch end is connected on, cam quantity is 3, and cam edge contacts with above-mentioned transmission fork; Above-mentioned rod hinge connection is in the uppermost cam end face of vertical shaft eccentric position place.
Transmission fork between above-mentioned cam and the crochet hook vertical motion executing agency contacts with following cam edge; Transmission fork between cam and the crochet hook horizontal movement executing agency contacts with middle cam edge; Cam and suture needle contact with top cam edge with the transmission fork between the moved further executing agency with dials.
Pollute workpiece because of need are oily for fear of each work package, on dials, establish one upright, opening upwards and housing with cover, this housing surrounds the transmission fork of each cam, cam edge and the connecting rod of cam end face, and the sidewall of housing has the outlet of transmission fork.
Transmission device of the present utility model has following advantage:
1, because three cams are contained on the same vertical shaft, and rocking bar is connected in uppermost cam, the synchronous rotation of three cams, the action that makes each motion is synchronous coordination more, has improved the precision of sewing machine, makes the needs of sewing up the high-grade meticulous stitching of functional adaptation.
2, be contained on the same vertical shaft owing to three cams, after can making the driving force of horizontal direction transfer the driving force of vertical direction earlier to, be converted into the driving force of another horizontal direction again, make the length of connecting rod that is connected with its edge shorten greatly, improve the rigidity of transmission device, reduce the vibration of dials, when having improved sewing machine precision, also make total seem compact.
3, because three cams are loaded on the same vertical shaft, so cam and transmission fork, connecting rod can be surrounded by a housing, the driving member of whole transmission device can not pollute workpiece and workbench because need are oily yet.

Specific embodiment
Shown in Fig. 2,3,4, transmission device of the present utility model reaches and with being connected of each motion is: the overlapping cam 3,4,5 that is equipped with on vertical shaft 7, and cam 3 edges are connected to transmission fork 10, and transmission fork 10 other ends connect rocker arm shaft 15; Cam 4 edges are connected to transmission fork 12, and transmission fork 12 other ends connect crochet hook connecting rod 16; Cam 5 edges are connected to transmission fork 13, and transmission fork 13 other ends connect another crochet hook connecting rod 18; End face eccentric position place at cam 3 also is hinged with connecting rod 11, and connecting rod 11 other ends connect rocker arm shaft 15.Its operation principle is: power drives three cams by vertical shaft and rotates simultaneously, and each cam promotes the transmission fork at edge and the connecting rod of cam 3 end faces separately, and the transmission fork 13 at cam 5 edges drives crochet hook connecting rods 18, by hooked needle shaft 17 crochet hook swung up and down; The transmission fork 12 at cam 4 edges drives crochet hook connecting rod 16, by hooked needle shaft 17 crochet hook is swung; The transmission fork 10 at cam 3 edges drives rocker arm shafts 15, by drawing pin rocking arm 14, suture needle and big dials are moved synchronously, the connecting rod 11 of cam 3 end faces drives rocker arm shaft 15, makes the suture needle swing by drawing pin rocking arm 14, thereby realizes crochet hook and the work of suture needle synchronous coordination.
Because driving member in the course of the work, often drip lubrication, and unnecessary lubricating oil easily sprays when driving member is worked, make workpiece contaminated, thereby a vertical cabinet 2 is set on dials, cam 3,4,5 and cam drive fork 10,12,13, connecting rod 11 are contained in the casing, the casing opening upwards, top, side has the outlet of cam drive fork, and unnecessary lubricating oil can be by the casing splendid attire, and the casing top is provided with a lid 1, when driving member need lubricate oiling or maintenance, lid is just opened, and during the transmission device operate as normal, lid is not opened.The bottom of casing also has an aperture, when the lubricating oil that accumulates reaches certain degree, can be discharged by aperture.Casing can also increase the rigidity of transmission device, reduces the vibration of dials, also makes structure compact more.
