The specific implementation scheme of the present invention is as follows:

[0022] A machine tool spindle installation tool comprises a fixed plate 8, a plurality of guide rollers 3 are arranged at vertical intervals at the lower part of the fixed plate 8, the guide roller 3 is provided with a connecting plate 11 in a sliding structure, the connecting plate 11 is provided with a bolt 4 for connecting a direct-connected spindle, and the connecting plate 11 acts as a link, which is convenient for lifting the direct-connected spindle; the screw 9 is connected to the fixed plate 8 by threaded engagement, and a limit piece is provided on the lower end face of the screw 9, and the limit piece is connected to the screw 9 in a detachable structure. The installation tool pushes the direct-connected spindle installed on the connecting plate into or out of the spindle box through the rotation of the screw, and plays a guiding role by setting a guide roller to connect with the existing spindle fixing hole on the spindle box, thereby improving the installation efficiency and accuracy, ensuring the installation quality, and improving the product quality of the core components.

[0023] Furthermore, eye screws 5 are provided on both sides of the connecting plate 11 by means of threaded engagement, and the directly connected spindle on the connecting plate 11 is hoisted to the spindle box by the eye screws 5 , which is convenient and quick.

[0024] It should be noted that a nut A12 is provided at the upper end of the guide roller 3 through the fixed plate 8, and a nut B13 is provided at the guide roller 3 at the lower part of the fixed plate 8. Both the nut A12 and the nut B13 are connected to the guide roller 3 by threaded engagement. A thread is provided at the lower part of the guide roller 3 for connecting to the existing spindle fixing hole on the axle box. The guide roller 3 is used to connect the spindle box and the fixed plate 8, and at the same time guide the direct-connected spindle 2 and the connecting plate 8 to move along the guide roller 3. The direct-connected spindle 2 is accurately put into the main hole of the box body under the push of the screw 9.

[0025] It should be explained that a handle 10 is provided on the upper portion of the screw rod 9 to facilitate the rotation of the screw rod 9 .

[0026] Specifically, the connecting plate 11 is provided with a through hole 6 for the screw rod 9 to pass through, that is, the screw rod 9 is not in contact with the connecting plate, which facilitates the movement of the screw rod 9 .

[0027] Specifically, the limiting member is a circular washer 7 , which is connected to the screw rod 9 via a bolt, and the diameter of the circular washer 7 is larger than the diameter of the through hole 6 .

[0028] The working principle and working process of this utility model are as follows:

[0029] (1) Clean and wipe the main hole of the spindle box and the direct-connected spindle;

[0030] (2) Using the four evenly spaced screw holes on the front cover of the direct-connection spindle, the lower end face of the direct-connection spindle 2 is fixedly connected to the upper end face of the connecting plate 11 by means of bolts 4;

[0031] (3) Use a lifting rope to hook the eye screw 5, lift the direct-connected spindle 2 vertically to the top of the main hole of the spindle box 1, and stop when it is 2 mm away from the main hole. Confirm the position and direction, and evenly apply a small amount of lubricating oil to the inside of the main hole of the box and the outside of the spindle sleeve;

[0032] (4) Pass the four guide rollers 3 from top to bottom through the guide holes of the connecting plate 11 and the large sleeve mounting and fixing holes of the direct-connected main shaft 2. The size of the guide hole of the connecting plate 11 is consistent with the size of the main shaft large sleeve and the mounting and fixing holes of the box body. Then screw the lower end of the guide roller 11 into the main shaft fixing hole of the box body. After confirming that the four guide rollers are connected, start the crane hook to move up and down, and observe whether the connecting plate 11 with the direct-connected main shaft 2 can move smoothly and accurately into the main shaft mounting hole under the guidance of the guide rod 3;

[0033] (5) After confirming that it can be accurately guided, adjust the direct-connected main shaft 2 to the appropriate position, first install the nut B on the upper end of the guide roller 3, connect the fixed plate 8 to the four guide rollers 3, and then install the nut A12 on the upper end of the guide roller 3. After adjusting the position, lock the fixed plate 8;

[0034] (6) Screw the screw 9 into the M30 center threaded hole of the fixing plate 8. After the screw passes through the center threaded hole, connect the round washer 7 to the end of the screw with an M12 hexagon socket screw, so that a Φ36 mushroom head is formed at the end of the screw 9;

[0035] (7) Rotate the handle 10 clockwise to move the screw rod vertically downward. When the mushroom head round pad 7 of the screw rod touches the center hole of the connecting plate 11, gently rotate the handle 10 while slightly lowering the crane rope. Observe that under the push of the screw rod 9, when the front and rear sealing rings of the main shaft sleeve are all inserted into the main hole of the box body, the gap between the direct-connected spindle mounting surface and the box body joint surface is about 12 mm. Confirm again that the box body end face and the main shaft sleeve joint surface are clean. After confirmation, loosen the rope appropriately and continue to rotate the handle 10 to push the direct-connected spindle 2 completely into the box body.

[0036] (VIII) Confirm that the direct-connected spindle 2 is in place, remove the crane rope, dismantle the device in the reverse order of installation, screw on the spindle fixing screw, and push-fit the direct-connected spindle 2. Conversely, if you want to dismantle the direct-connected spindle 2, just remove the round washer 7 at the end of the screw 9, and after the screw 9 passes through the through hole 6, install the round washer at the bottom of the through hole 6 with the bolt. Then, with the help of the crane, hang the rope and hook the left and right eye screws 5 of the connecting plate. Rotate the handle 10 counterclockwise, the screw 9 rises, the crane rope rises, and the round washer 7 pulls the connecting plate 11 upward, thereby gradually disengaging the direct-connected spindle 2 from the main hole until it is completely disengaged.
