Abstract
The invention relates to a dismounting device for a main shaft bearing of a polishing machine. The dismounting device comprises a circular disc, a screw nut, a pulling hook screw rod and a top thread screw rod, wherein one end of the pulling hook screw rod passes through a hole arranged at the outer edge of the circular disc and is fastened on the circular disc through the screw nut, the top thread screw rod passes through a hole arranged in the center of the circular disc to be movably connected with the circular disc through a chain and can move in the vertical direction, when the bearing is dismounted, the main shaft bearing is hooked by the pulling hook screw rod, then, the top thread screw rod upwards moves for driving the circular disc to upwards move, the circular disc drives the main shaft bearing to upwards move, and the main shaft bearing is dismounted. Compared with the prior art, the dismounting device has the advantages that the overhaul time is short, the dismounting is convenient, and the like.
Description
Technical field
The present invention relates to a kind of provision for disengagement of bearing, especially relate to a kind of provision for disengagement for main shaft bearing of polishing machine.
Background technology
Existing plate nitre polishing machine, although compact to design reasonable, when the repair demolition of main shaft bearing, then workload is huge.Need to take out whole gearbox; comprehensively disintegrate; and then one by one part and bearing are loaded onto in order; so often need just to finish the work of changing main shaft bearing 5 times about working day; utilization rate on equipment has certain impact; shutting down cost has increased, and the daily production of the company that directly has influence on affects finishing on schedule of order.
Summary of the invention
Purpose of the present invention is exactly the provision for disengagement that is used for main shaft bearing of polishing machine that short, convenient disassembly of a kind of repair time is provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of provision for disengagement for main shaft bearing of polishing machine, it is characterized in that, comprise disk, nut, drag hook screw rod and jackscrew screw rod, described drag hook screw rod one end passes the hole of disk outer rim, by fastening nuts on disk, described jackscrew screw rod passes hole and the disk active link of disk central authorities, can move in vertical direction, during the dismounting bearing, hook main shaft bearing by the drag hook screw rod, then the jackscrew screw rod moves up and drives disk and move up, and disk drives main shaft bearing and moves up, and main shaft bearing is disassembled.
Described jackscrew screw rod upper end is provided with rocking bar.
Compared with prior art, the present invention has the following advantages:
1, the repair time shortens;
2, convenient disassembly;
3, maintenance workload reduces.
Description of drawings
Fig. 1 is structural representation of the present invention
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of provision for disengagement for main shaft bearing of polishing machine, comprise disk 1, nut 2, drag hook screw rod 3 and jackscrew screw rod 4, wherein an end of drag hook screw rod 3 passes the hole of disk 1 outer rim, is fastened on the disk 1 by nut 2, and jackscrew screw rod 4 passes hole and disk 1 active link of disk 1 central authorities, can move in vertical direction, during the dismounting bearing, hook main shaft bearing by drag hook screw rod 3, then jackscrew screw rod 4 moves up and down the dismounting that realizes main shaft bearing.Described jackscrew screw rod 4 upper ends are provided with rocking bar.
