Abstract
The utility model relates to a new driving mechanism of a sewing machine. A power mechanism can be used for driving a gear set and an intermittent mechanism through a power steering mechanism which is connected with the power mechanism; the intermittent mechanism is composed of a worm screw which is provided with parallel slot teeth and oblique parallel slot teeth and a drive gear which is meshed with the worm screw; the drive gear can be used for driving a shaft lever and a roller shaft which is connected with the shaft lever for rotation; when the parallel slot teeth segment on the worm screw circumference is engaged with the drive gear, the drive gear can not rotate; when the oblique parallel slot teeth segment on the worm screw circumference is engaged with the drive gear, the drive gear can rotate in forward and reverse directions. An electromagnetic clutch is arranged between a driving mechanism and the intermittent mechanism for acting a part in the forward and reverse intermittent actions of the worm screw.
Description
The utility model relates to the transmission mechanism of a kind of sewing machine, particularly a kind of sewing machine.
The transmission mechanism of traditional sewing machine all uses ratchet to promote gear and then drives roller and rotates, so that the cloth Shu of car flower goes ahead.The existing problem of this ratchet-type pushing mechanism is: ratchet causes the toothrow of gear impaired in the interlock rotation process easily, causes the damage of part.After parts depreciation or gear are cracked a joke, then can cause disconnected retaining and knitting in the transmission process, thereby cause the needle gage of the decorative pattern that cloth Shu car goes out not of uniform size, influence product quality.In addition, the ratchet pushing mechanism can only promote forward, and can't oppositely promote, so cloth Shu also can only be pushed toward a direction, has brought inconvenience to process and operation.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provide a kind of by intermittence worm screw promote the forward and reverse rotation of gear, be difficult for cracking a joke, car flower machined needles is apart from the transmission mechanism that keeps certain sewing machine.
The purpose of this utility model is to realize by following technical scheme: actuating unit turns gear train and the electronic-controlled power steering mechanism by companys of driving with it turns the indexing mechanism rotation, intermittently machine is provided with the worm screw of parallel slot tooth and dip-parallel groove tooth by one and the travelling gear that is meshed with worm screw is formed, the roller shaft rotation that travelling gear drives axostylus axostyle and links to each other with axostylus axostyle, when circumferential parallel slot tooth section of worm screw and travelling gear engagement, then travelling gear does not rotate, when circumferential dip-parallel groove tooth section of worm screw and travelling gear engagement, travelling gear then just, backward rotation.As an electromagnetic clutch is set, then also can play forward and reverse intermittent action of worm screw between rotating mechanism and indexing mechanism.
Therefore: remarkable result of the present utility model is:
1. by the applying of batch (-type) worm screw, can realize rotating forward and reverse intermittence.
2. worm screw intensity is good, stable drive, the not teeth of fragile travelling gear.
3. can guarantee that needle gage is certain, helps improving the quality of products.
4. simple in structure, reliable.
Order body structure of the present utility model realized by the following examples and accompanying drawing thereof,
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is the structure enlarged drawing of Fig. 1 discontinuous worm screw.
Below in conjunction with accompanying drawing 1-2 concrete structure of the present utility model is described in detail
The dynamic mechanism 1 of the utility model, actuating unit 1 and gear train 2 companies of driving, 3 companies of driving of steering mechanism that actuating unit 1 and bevel gear constitute, steering mechanism 3 links to each other with batch (-type) driving rotation mechanism 4, batch (-type) driving rotation mechanism 4 drive shaft rods 6 reach and axostylus axostyle 6 roller set 5 rotations of interlock mutually, it is characterized in that: batch (-type) driving rotation mechanism 4 is to be made of batch (-type) worm screw 41 and the travelling gear 42 that is meshed with batch (-type) worm screw 41, batch (-type) screw rod 41 is that the dip-parallel tooth section 412 by the parallel teeth section 411 of two groups of symmetries of basic bar 413 circumferential projection and two groups of symmetries constitutes, and two parallel teeth sections 411 and two dip-parallel tooth sections 412 seamlessly transit and constitute intermittently worm screw 41 of curve-like.Referring to Fig. 1 and Fig. 2
Architectural feature of the present utility model also is:
Between electronic-controlled power steering mechanism 3 and batch (-type) driving rotation mechanism 4, be provided with and install an electromagnetic clutch additional.
Operation principle of the present utility model is:
The electronic-controlled power steering parts 3 that constitute at the capable gear of umbrella with intermittence 4 of driving rotation mechanisms add an electromagnetic clutch, can control the driving rotation mechanism at intermittence of sewing machine and 4 make forward and backward, and then allow cloth Shu 7 that desire on the roller 51 of roller set 5 does the processing of car flower forward along with or fall back away.
See also shown in figure two and the cooperation figure one, intermittently worm screw 41 is provided with several parallel teeth groove section 411 in the upper end downwards in week, and each parallel teeth groove section 411 engages with inclination teeth groove section 412; When intermittence, worm screw 41 engaged transmission gears 42 rotated, when this intermittence, rainwater in puddles bar 41 turned to parallel teeth groove section 411, at this moment, travelling gear 42 promptly is in halted state, and when intermittently worm screw 41 turns to inclination teeth groove section 412, this intermittently worm screw 41 will promote that travelling gear 42 is done forward or rotation backward.
Claims (2)
1, a kind of transmission mechanism of sewing machine, dynamic mechanism 1, actuating unit 1 and gear train 2 companies of driving, 3 companies of driving of steering mechanism that actuating unit 1 and bevel gear constitute, steering mechanism 3 links to each other with batch (-type) driving rotation mechanism 4, batch (-type) driving rotation mechanism 4 drive shaft rods 6 reach and axostylus axostyle 6 roller set 5 rotations of interlock mutually, it is characterized in that: batch (-type) driving rotation mechanism 4 is to be made of batch (-type) worm screw 41 and the travelling gear 42 that is meshed with batch (-type) worm screw 41, batch (-type) screw rod 41 is that the dip-parallel tooth section 412 by the parallel teeth section 411 of two groups of symmetries of basic bar 413 circumferential projection and two groups of symmetries constitutes, and two parallel teeth sections 411 and two dip-parallel tooth sections 412 seamlessly transit and constitute intermittently worm screw 41 of curve-like.
2, according to the transmission mechanism of the described a kind of sewing machine of claim 1, it is characterized in that: between electronic-controlled power steering mechanism 3 and batch (-type) driving rotation mechanism 4, be provided with and install an electromagnetic clutch additional.
