[0048] The present invention also proposes a method for using a positioning guide device for disassembling and assembling a tapered roller of a ring rolling machine, comprising the following steps:

[0049] Step 1: First, power on the motor and electronic components of the device, then push the device to the cone roller disassembly location, then start the lifting motor 22, so that the lifting screw 25 rotates to drive the lifting slide 7 down to prevent the connection card frame 26 from blocking the entry of the inclined cone roller. Then continue to push the device so that the front end of the cone roller enters the device, then start the lifting motor 22 again, so that the connection card frame 26 rises and is supported on the lower end of the cone roller, and at the same time, the connection card frame 26 deflects between the two lifting slides 7, so that the abutment surface of the connection card frame 26 can better abut the side end of the cone roller.

[0050] Step 2, then start the second linear motor to drive the third lifting assembly to move forward to the inner side of the device. When it moves to the front end of the first slide rail 23, adjust the positions of the two movable limit blocks 6 so that the two movable limit blocks 6 are close to the entry side of the cone roller, and loosen the limit fixing nut, so that the sliding limit frame 20 is lifted and lowered on the movable limit blocks 6, so that the arc groove on the raised sliding limit frame 20 supports the cone roller, and then tighten the limit fixing nut. At the same time, lower the connecting card frame 26, and drive the third lifting assembly to move backward through the first linear motor until the third lifting assembly returns to the initial position. Then raise the connecting card frame 26 again, so that the connecting card frame 26 supports the cone roller again. Then lower the sliding limit frame 20 through the second lifting assembly, and loosen the support of the sliding limit frame 20 on the cone roller.

[0051] Step 3: Then, the third lifting assembly is pushed forward again by the first linear motor, so that the connecting clamp frame 26 pushes the cone roller forward again. The cone roller is continuously pushed forward by the above operation until the cone roller extends into the clamping support mechanism, and the two clamping limit sleeves 15 on the clamping support mechanism clamp and support the cone roller. Then, the front and rear positions of the movable limit block 6 are adjusted, and the limit fixing nut on the movable limit block 6 is loosened, and then the height of the sliding limit frame 20 is adjusted so that the arc groove on the sliding limit frame 20 is clamped and fixed in the stepped groove of the cone roller.

[0052] Step 4: Then adjust the sliding and pressing adjustment mechanism, and push the abutment plate 16 by rotating the adjustment bolt, so as to adjust the first spring 17 to push the connecting sleeve block and the connecting rod 18, so that the clamping limit sleeve 15 can stably clamp and fix the cone roller. When the connecting clamp frame 26 is at the step groove of the supporting cone roller, the limit convex block 27 is pushed out by the second spring 29, and the pushed limit convex block 27 can be clamped in the step groove, so as to better fix the cone roller and make the sliding of the cone roller more stable.

[0053] Step 5, finally start the second linear motor, which drives the two sliding boxes 8 to approach each other, so that the push rollers 35 on the two sliding boxes 8 abut against the cone roller. The rotary motor in the second sliding box 8 drives the connecting shaft 32 to rotate, and the connecting shaft 32 drives the connecting seat 33 to rotate, so that the push roller 35 abuts against the cone roller in parallel, and cooperates with the connecting clamp frame 26 to complete the abutment of the cone roller. Through the setting of the connecting seat 33 and the push motor 34, the pushing and rotation adjustment of the cone roller can be realized. At this point, the cone roller disassembly and assembly of the device is completed, and the steps for installing the cone roller are reversed.
