Description
Technical Field
The utility model relates to an industrial sewing machine field, especially a sewing machine clutch.
Background
The currently used zigzag sewing flat sewing machine encounters the thread jamming of the rotating shuttle in the sewing process or other misoperation, such as when leather, cloth and the like are clamped into the rotating shuttle, and the lower shaft still runs, so that the damage of the rotating shuttle and other safety accidents can be caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the sewing process of the zigzag sewing flat sewing machine, the utility model provides a clutch device of the sewing machine.
This kind of sewing machine clutch, including the bearing housing, a bearing, the jump ring, lower synchronizing wheel, the steel ball, sleeve and pressure regulating screw, a serial communication port, telescopic left end passes through the jump ring and links together with lower synchronizing wheel, lower synchronizing wheel passes through the bearing and installs on the tip of bearing housing, 180 symmetrical arrangement has 2 through-holes on the sleeve, the steel ball has been placed in proper order in the through-hole, spring and gasket, the through-hole right-hand member pins through pressure regulating screw, 180 symmetrical arrangement has the blind hole on the terminal surface of lower synchronizing wheel and steel ball contact.
Furthermore, a belt is meshed outside the small end of the lower synchronizing wheel, and the other end of the belt is meshed with the upper synchronizing wheel.
Further, a lower shaft is installed in the center of the sleeve, and an upper shaft is installed in the upper synchronizing wheel.
The beneficial effects of the utility model are that when the material was gone into to rotating shuttle card line or rotating shuttle mistake in sewing machine sewing process, can realize that the lower shaft breaks away from the transmission relation to guarantee that the rotating shuttle is not damaged, avoid appearing the incident.
Drawings
Fig. 1 is a schematic view of the structure of the present invention
FIG. 2 is a schematic view of the clutch part
In fig. 1 and 2, (1), a sleeve, (2), a pressure regulating screw, (3), a double gasket, (4), a spring, (5), a steel ball, (6), a lower synchronizing wheel, (7), a snap spring, (8), a bearing, (9), a bearing sleeve, (10), a lower shaft, (11), a belt, (12), a synchronizing wheel, (13), an upper shaft, (14), a through hole, (15) and a blind hole.
Detailed Description
The invention will be further described in the following with reference to the accompanying drawings in which specific embodiments are shown.
In the figures 1 and 2, the clutch device of the sewing machine comprises a bearing sleeve (9), a bearing (8), a clamp spring (7), a lower synchronizing wheel (6), a steel ball (5), a sleeve (1) and a pressure regulating screw (2), and is characterized in that the left end of the sleeve (1) is connected with the lower synchronizing wheel (6) through the clamp spring (7), the lower synchronizing wheel (6) is installed on the small end of the bearing sleeve (9) through the bearing (8), 2 through holes (14) are symmetrically arranged at 180 degrees on the sleeve (1), the steel ball (5), a spring (4) and a gasket (3) are sequentially placed in the through holes (14), the right end of the through hole (14) is locked through the pressure regulating screw (2), blind holes (15) are symmetrically arranged at 180 degrees on the end face, which is contacted with the steel ball (5), of the lower synchronizing wheel (6), a belt (11) is meshed outside the small end of the lower synchronizing wheel (6), and an upper synchronizing wheel (12) is meshed with the other end of the belt (11, the center key of the sleeve (1) is connected with a lower shaft (10), and the middle key of the upper synchronizing wheel (12) is connected with an upper shaft (13).
When the device is used, the large end of the bearing sleeve (9) is fixed on the shell, the upper shaft (13) rotates to drive the upper synchronizing wheel (12) to move, the upper synchronizing wheel (12) drives the lower synchronizing wheel (6) to move through the belt (11), the lower synchronizing wheel (6) drives the sleeve (1) to rotate through the steel balls, so that the lower shaft (10) is driven to operate, due to the fact that the double steel balls (5) are adopted, the double springs (4), the double gaskets (3) and the double pressure regulating screws (2) are symmetrical about 180 degrees of the axis, so that the stress is uniform, the practical service life of the whole device is prolonged, the pressure regulating screws (2) can increase the pretightening force, the steel balls (5) are located in the blind holes (15), when the rotating speed is too fast, the steel balls (5) are separated from the blind holes (15).
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
Claims (3)
1. The utility model provides a sewing machine clutch, including the bearing housing, a bearing, the jump ring, the synchronizing wheel, the steel ball, sleeve and pressure regulating screw, a serial communication port, telescopic left end links together through jump ring and lower synchronizing wheel, lower synchronizing wheel passes through the bearing and installs on the tip of bearing housing, 180 symmetrical arrangement has 2 through-holes on the sleeve, the steel ball has been placed in proper order in the through-hole, spring and gasket, the through-hole right-hand member pins through the pressure regulating screw, 180 symmetrical arrangement has the blind hole on the terminal surface of lower synchronizing wheel and steel ball contact.
