Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the present invention provides a special bearing mounting device for mounting a first bearing a1 and a second bearing a2 into a guide wheel B. The special bearing installation device comprises a base 1, a positioning screw rod 2, a lower pressing block 3 and an upper pressing block 4.
The positioning screw rod 2 is vertically arranged, and the bottom end of the positioning screw rod is fixed on the base 1.
The lower pressing block 3 is sleeved on the positioning screw rod 2 and fixed on the base 1, and particularly, the lower pressing block 3 is fixed on the base 1 through a screw.
Go up compact heap 4 and have the briquetting screw hole, its internal thread and positioning screw 2's external screw thread phase-match, go up compact heap 4 accessible screw hole threaded connection cover on positioning screw 2.
The first bearing A1, the guide wheel B and the second bearing A2 are sequentially sleeved on the positioning screw rod 2, when the first bearing A1, the guide wheel B and the second bearing A2 are located between the lower pressing block 3 and the upper pressing block 4, the upper pressing block 4 is rotated to move downwards along the positioning screw rod 2, and the first bearing A1 and the second bearing A2 are pressed into the guide wheel B by the upper pressing block 4.
