Abstract
The utility model relates to a clutch slide block for a sewing machine with two sewing heads. The utility model is characterized in that the outer circle of one end of the clutch slide block is provided with circumferential teeth 13, and the outer circle of the other end of the clutch slide block is provided with teeth 14; a convex circular clamping block is arranged between the circumferential teeth 13 and the teeth 14, and the inner circle of the clutch slide block is also provided with teeth 15. The clutch slide block is mainly used in a double-head sewing machine, and can distribute dynamic force and transfer dynamic force under the cooperation of a belt wheel, a shaft sleeve and a shift fork. The utility model has the advantages of compact structure, small volume and flexible use.
Description
The utility model relates to the clutch in the machine driving, specifically a kind of clutch slip piece that is mainly used in double-head sewing machine.
Though the application of clutch in machinery is very general, its function mostly is under the situation of not cutting off the electricity supply, control mechanically operated interruption or lasting, the general employing of structure is provided with tooth on the surface of clutch, power is from fixed block, reach above function by the sliding shoe of clutch and the engagement or the disconnection of fixed block, but can not play the effect of distributed power and direction of transfer.In the structure of common Sewing machines, be that clutch is not set, but in the design of carrying out double-head sewing machine, space with the logical flat seam machine of a Daepori holds flat seam machine, overlock machine, and adopt a power source to carry out the transmission of power distribution and power, the all functions that both kept original two machines, embody compact conformation again, occupy the little characteristic in space.
The purpose of this utility model is to provide a kind of clutch slip piece that is used for double-head sewing machine, and it can carry out the transmission of power distribution and power.
The technical solution of the utility model is achieved in that a kind of clutch slip piece that is used for double-head sewing machine, it comprises axis hole and the tooth that is arranged on the clutch slip piece in the clutch slip piece, it is characterized in that: the cylindrical of clutch slip piece one end is provided with circumferential teeth 13, the cylindrical of the other end is provided with tooth 14, also be provided with a circular fixture block that protrudes in circumferential teeth 13 and 14 in tooth, within the clutch slip piece, also be provided with tooth 15 in the circle.
The utility model is owing to be provided with tooth in an end of the two ends of clutch cylindrical and interior circle, on cylindrical, also be provided with the circular fixture block of protrusion, be contained in clutch slip piece on the axle sleeve under the cooperation of belt wheel, axle sleeve and the shift fork of clutch fixed block, can carry out the transmission of power distribution and power, the general idea novelty, and compact conformation, volume is little, and is easy to operate.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the E of Fig. 1 is to side view
Fig. 3 is that the F of Fig. 1 is to side view
Fig. 4 is the assembling schematic diagram of the utility model in double-head sewing machine
The utility model will be further described below in conjunction with drawings and Examples
The utility model is the clutch slip piece that is used for double-head sewing machine, it comprises axis hole 10 and the tooth that is arranged on the clutch in the clutch slip piece, its difference with prior art is: the cylindrical of clutch slip piece one end is provided with circumferential teeth 13, this circumferential teeth 13 is a spline tooth, the formed track of its tooth top and tooth root is the circumference coaxial with the cylindrical of clutch slip piece, in circumferential teeth 13 and 1 of circular fixture block escape 11 is arranged; The other end on clutch slip piece cylindrical is provided with tooth 14, and tooth 14 is a contrate tooth profile, and the formed track of its tooth top and tooth root is the transverse plane perpendicular with clutch slip piece axis hole 10; Also be provided with tooth 15 in the circle within the clutch slip piece, tooth 15 be a circumferential teeth, with tooth 14 same ends, the formed track of its tooth top and tooth root be with the clutch slip piece in justify coaxial circumference; Side at tooth 15 also is provided with escape 12, and in sum, the excircle of clutch slip piece has three flights; Inner periphery has two flights.
This clutch slip piece slides on the axle sleeve 3 of clutch fixed block, axle sleeve 3 is fixed tightly on the bent axle 6 of flush joint system, on the cylindrical of axle sleeve, external spline teeth is arranged, be provided with belt wheel 2 at an end of clutch sliding shoe as fixed block, interior circle at belt wheel 2 has inner spline gear, the right-hand member of tooth has escape, during assembling, the cylindrical circumference spline tooth 13 of clutch slip piece is maintained fixed engagement with interior round all spline tooths of belt wheel 2, the other end of clutch slip piece has belt wheel 5, be processed with the end tooth that matches with the tooth 14 of clutch slip piece on the belt wheel 5, tooth on when assembling belt wheel 5 not with tooth 14 engagements of clutch slip piece, belt wheel 5 reaches the overseam system by belt 9 with power, and shift fork 4 covers on the part circumference of fixture block 1 of clutch slip piece.Power connection, power is passed to the clutch slip piece by belt wheel 2 by spline tooth, the clutch slip piece is rotated, when the fixture block 1 of clutch slip piece is stirred when moving to left vertically by shift fork 4, tooth 14 on its left end face meshes with the tooth of belt wheel 5 its right end face, power reaches belt wheel 5, reaches the overseam component of a system through belt 9, makes the overseam system enter duty; When the fixture block 1 of clutch slip piece is stirred when moving to right vertically by shift fork, the spline tooth engagement on the spline tooth 15 in it on round week and the axle sleeve 3 cylindrical circumference, power reaches axle sleeve 3, drives bent axle 6 runnings, thereby makes the flush joint system enter duty; When the fixture block 1 of clutch slip is stirred when shifting to the centre position by shift fork 4, promptly be in when neither also not meshing with axle sleeve 3 with belt wheel 5, then overseam, flush joint system are neither in running order, drive friction pulley 7 by belt wheel 2 this moment, tighten up the axle 8 that links to each other with friction pulley 7 and also rotate the usefulness of the core that can wind the line synchronously.
