Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1 in conjunction with Figure 2 and Figure 3, the bearing dismounting device designed by the utility model includes a base 8, and four pillars 3 arranged on the base 8, and the middle part of the four pillars 3 is covered with a movable baffle 4 , the upper part is connected with a screw rod baffle 2; the base 8 is provided with a sleeve 11, and three radially arranged top wires 10 are evenly distributed on the peripheral wall of the sleeve 11; Install the shaft 12, the top of the installation shaft 12 is provided with the main screw 1 that vertically runs through the movable baffle 4 to the top of the screw baffle 2; the main screw 1 and the installation shaft 12 are connected with a detachable small screw, the small screw The rod is located between the middle part of the movable baffle plate 4, the main screw mandrel 1 and the mounting shaft 12 connected with the block 9. The movable baffle 4 is connected with a claw 6 below the movable baffle 4, and the claw 6 is radially positioned by the fixed bracket 5 fixed below the movable baffle 4, and the claw 6 is axially positioned by a stopper 9 whose bottom is connected to the mounting shaft 12.

There are three claws 6, the top of the claws 6 runs through the U-shaped groove 13 set by the movable baffle 4, and is fixed by the claw connecting plate 14, the block 9 below the claws 6 is a trapezoidal block, and the trapezoidal block and Mounting shaft 12 links to each other; Claw 6 lower bar body is connected with fixed bracket 5 by fixed bracket connecting rod 15, and fixed bracket 5 top is fixed on movable baffle plate 4, and the bottom connects claw 6 by fixed bracket connecting rod 15, and fixed bracket connects One end of the rod 15 is fixedly connected to the claw 6, and the other end is connected to the fixed bracket 5 through a nut.

The utility model has a simple principle and adopts the combined principle of compression and puller. The whole device is composed of five parts: first, the screw part (the small screw connected to the bottom is detachable); second, the screw baffle; third, the movable baffle, which has three 120-degree angles on its upper U-shaped groove, three claws are installed, and a stopper is welded at the bottom of the claws. One end of the stopper is square and the other end is trapezoidal. A fixed bracket matching the three claws is welded on its lower end for positioning the card.
