FIG. 3 is a schematic view of the bearing structure of the present invention;

in the figure, the device comprises a stepping motor 1, a mounting plate 2, a crank 3, a double bearing 4, a connecting rod 5, a connecting rod 6, a sliding rod seat 7, a bearing 8 and a sliding rod.

Detailed Description

As shown in the attached drawings, the utility model relates to an inorganic oil lubrication type slide bar device, including step motor 1, mounting panel 2, crank 3, duplex bearing 4, connecting rod 5, slide bar seat 6, bearing 7, slide bar 8.

Step motor 1 is the actuating mechanism of whole equipment, step motor 1 front end fixed mounting panel 2 that sets up, mounting panel 2 makes things convenient for to be connected in step motor 1 and sewing machine presser foot seat, the through-hole is seted up to mounting panel 2 middle part, the through-hole diameter size is the same with 3 rotating diameter of crank, in 3 installation through-holes of crank, 1 main shaft front end of step motor is cup jointed fixedly to the crank, 3 other ends of crank pass through duplex bearing 4 and connect 5 upper ends of connecting rod, slide bar 8 is connected to 5 lower extremes of connecting rod, 3 cranks drive 5 up-and-down motions of connecting rod, 5 motions of connecting rod drive slide bar 8 and do. A sliding rod seat 6 is arranged below the mounting plate 2, the sliding rod seat 6 is fixed on the end surface of the mounting plate 2, and the sliding rod seat 6 plays a role of supporting a sliding rod 8; four bearings 7 are correspondingly arranged at four corners of the upper end surface of the sliding rod seat 6, the peripheral surfaces of the bearings 7 are of U-shaped annular groove structures, the sliding rod 8 is arranged in the cracks of the four bearings 7, the inner walls of the annular grooves on the peripheral surfaces of the bearings 7 are of smooth design structures, the sliding rod 8 stretches and retracts in the cracks of the four bearings 7 to move back and forth, machine oil does not need to be added, the automatic cloth feeding of the cloth can be pushed to perform sewing work, the automatic operation of direct drive control is achieved, and the working efficiency is high.

The working principle is as follows: the slide bar and the four U-shaped surface bearings are matched to move to replace the previous mechanical complex operation structure action, no engine oil is required to be added, and the work of pushing the cloth to automatically feed the cloth to sew can be finished under the work of the stepping motor 1.
