Abstract
The utility model relates to a part of sewing machine, in particular to a motor connection structure of direct-driven sewing machine, which adopts technical proposal that: the part comprises a unit head and a motor fixing plate arranged at rear end of the unit head, a motor is arranged fixedly on the motor fixing plate by screws, the middle part of the motor fixing plate is provided with a through-hole that can be perforated by the motor, the main shaft of the motor is connected with the spindle of the sewing machine by a coupler assembly, the bottom surface of the rear-end pit of the unit head is provided with a mounting surface, the motor fixing plate is arranged fixedly on the mounting surface. The utility model has the advantages that: the motor fixing plate is embedded on the bottom surface of the rear-end pit of the unit head, the installation position of the motor is moved towards the left, so as to shorten the distance that the motor is exposed outside the unit head, so that the vibration of sewing machine is reduced greatly, thereby improving entire performance of sewing machine at the max intent and also shortening the length of sewing machine, moreover the packing dimension is reduced and the transportation cost is lowered.
Description
Technical field:
The utility model relates to accessaries of sewing machine, particularly a kind of motor connecting structure that directly drives Sewing machines.
Background technology:
The annexation of direct driving motor that uses and machine spindle as shown in Figure 1 at present, general all is that motor fixing plate 2 is fixed on the back pit end of head 1 along the P place by screw 3, motor 6 is fixed in motor fixing plate 2 outer ends by screw 7, motor fixing plate 2 middle parts are shaped on through hole, motor 6 main shaft the inners are passed this through hole and are utilized coupling assembly 4 to be connected with machine spindle, coupling assembly 4 outsides are provided with a plurality of screws 5 and fix, and motor 6 main shaft outer ends are installed with handwheel 8 by screw 9.Because the end that is connected with motor fixing plate 2 is distant from the pit bottom surface of bearing cap distance along P, the motor 6 that is installed on head 1 rear end like this can stretch out more, thereby cause the center of gravity of Sewing machines to move to right, the destabilizing factors such as vibrations increasing that cause Sewing machines, Package size strengthens simultaneously, and cost of transportation increases.
The utility model content:
The purpose of this utility model provides a kind of simple and compact for structure, motor connecting structure that directly drives Sewing machines of improving the complete machine performance.
The technical solution of the utility model is: comprise head, be installed on the motor fixing plate of back-end of machine head, motor is installed in motor fixing plate by screw, the motor fixing plate middle part is shaped on the through hole that the power supply machine main shaft penetrates, electric machine main shaft is connected with machine spindle by coupling assembly, back-end of machine head pit bottom surface is provided with installed surface, and motor fixing plate is installed on this installed surface.
Installed surface is placed in outside the machine spindle bearing, is connected in the above-mentioned pit of motor fixing plate setting-in and by screw and installed surface.Motor fixing plate is made up of a plurality of cushion blocks, packing ring closed assembly.
The utility model has the advantages that: motor fixing plate is flush-mounted in the pit bottom surface, rear end of head, the motor installation site is moved to the left, shorten motor effectively and be exposed at the outer distance of head, thereby the vibrations of Sewing machines are significantly reduced, improve the overall performance of Sewing machines to greatest extent, the contraction in length of while Sewing machines, Package size reduces, and cost of transportation reduces.
Description of drawings:
Fig. 1 directly drives the motor connecting structure of Sewing machines for tradition.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 2, the pit bottom surface, rear end of head 1 is provided with an installed surface M, and this installed surface M is placed in bearing, and bearing cap and installed surface M are on same vertical plane, or the relative installed surface M of bearing cap slightly outwards protrudes.Installed surface M is shaped on a plurality of screws, and this pit of motor fixing plate 2 setting-ins is loaded on installed surface M by screw 3, and motor 6 is installed on the outer end of motor fixing plate 2 by screw 7.Motor fixing plate 2 middle parts are shaped on through hole, and motor 6 main shaft the inners are passed through hole and utilized coupling assembly 4 to be connected with machine spindle, and coupling assembly 4 outsides are provided with a plurality of screws 5 and two main shafts are fixed, and motor 6 main shaft outer ends are with handwheel 8, and fixing by screw 9.Motor fixing plate 2 can be the plate of integral type, also can be made up of a plurality of cushion blocks, packing ring closed assembly, and motor fixing plate 2 damping effects of closed assembly are better.
