In order to overcome drawbacks described above, the utility model provides a kind of upper needle plate Bearing sleeve auxiliary fixing device, not only
Installation is simple, and stability is good.
The utility model in order to solve its technical problem used by technical scheme be：A kind of upper needle plate Bearing sleeve auxiliary
Fixing device, including upper needle plate and lower needle plate, the lower needle plate are provided with guide pillar, and the upper needle plate corresponds to the guide pillar position and set
There is a Bearing mounting hole, be provided with Bearing sleeve in the Bearing mounting hole, the opening of the Bearing sleeve is towards on the lower needle plate
Guide pillar, the upper side of the upper needle plate is located at the mounting hole periphery and is provided with Bearing fixed seat, and the Bearing fixed seat has
Upper bottom surface and at least two outside-supporting faces, the upper bottom surface of the Bearing fixed seat are provided with the first screw installing hole, the training
The upper bottom surface of woods sleeve is provided with the second screw installing hole；It is additionally provided with Bearing fixed screw and Bearing location nut, the Bearing
Screw rod one end of fixed screw is sequentially passed through after the second screw installing hole, the first screw installing hole out of described Bearing sleeve by institute
Bearing location nut is stated to fix.
As further improvement of the utility model, the screw rod outer face of the Bearing fixed screw is revolved provided with screwdriver
Enter groove.
As further improvement of the utility model, the inner face of the screw rod of the Bearing fixed screw is provided with withdrawing
Groove.
As further improvement of the utility model, the Bearing fixed seat is cylindrical shape.
The beneficial effects of the utility model are：Needle plate Bearing sleeve auxiliary fixing device on upper needle plate by setting on this
Bearing fixed seat, Bearing sleeve is pulled in the Bearing mounting hole of upper needle plate by Bearing fixed screw and Bearing location nut and
Bearing fixed seat is fixed, not only easy for installation, is interference fitted without using hammer, and Bearing sleeve passes through Bearing fixed screw
It is fixed on Bearing location nut in Bearing fixed seat, and the outside-supporting face of Bearing fixed seat is supported in the upper side of needle plate
On so that Bearing sleeve is tensed upwards by Bearing fixed seat all the time, will not fall off, substantially increase Bearing sleeve stability and
Service life.
