[0024] The present invention will be further described below with reference to the accompanying drawings. The high-speed section disassembly and assembly tool includes a base plate 1 and a guide rail 2, and also includes a support column 12, which is disposed on the base plate and is used to support one end of the cross pin 9 (specifically, during disassembly, it can be supported on the first bracket 91 of the cross pin - two need to be set; during installation, it is supported on the bottom end face of the second bracket - only one needs to be set); a support frame 21 is disposed on the guide rail, and its top end is provided with an installation groove 211 for placing the shaft 93 of the high-speed section; a crossbeam 13 is mounted on the base plate and is equipped with a liftable pressure mold driven by a power source 94. The pressure mold is detachably connected to the power source and includes a first pressure mold 31 or a second pressure mold 32. The first pressure mold is disposed opposite to the second bracket 95 of the cross pin; the second pressure mold is disposed opposite to the bearing 91 at the top of the cross pin. Meanwhile, the base is provided with a long groove 18 to adjust the installation position of the support column. The bottom of the support column is a plate that fits with the long groove, which can be used to accommodate shafts of different lengths and as a support during installation. Of course, threaded holes in different positions can also be provided to install support frames in different positions.

[0025] Disassembly steps

[0026] 1. Use snap ring pliers to remove the four corresponding snap rings (99) from the output shaft (cross shaft).

[0027] 2. Select the corresponding first die and thread it onto the connecting rod.

[0028] 3. The two ends of the first bracket at the high-speed section half-shaft are placed on the support columns.

[0029] 4. Adjust the V-blocks on the guide rails until the product is visually positioned horizontally.

[0030] 5. When the first die is pressed down, place one hand lightly on the product's safe position behind the V-block to prevent the product from shifting due to force. Press down to the appropriate position (you will hear a sound of it falling off). The specific process is that the bottom end face of the first die presses on the second bracket, causing it to descend vertically. This exposes the bearing inside (its structure from the inside out consists of the journal, bearing, and bracket). At this point, it can be easily removed manually.

[0031] 6. Loosen the return valve (fine adjustment), and after completing one angle, rotate the shaft to perform the same operation in the other direction.

[0032] Assembly steps of the cross shaft for high-speed products

[0033] 1. Select a second pressure head and assemble it onto the push rod of the hydraulic cylinder or the connecting rod of the push rod;

[0034] 2. Place the bracket on the journal accordingly.

[0035] 3. Place the needle roller bearing into the mounting hole of the bracket.

[0036] 4. Adjust the V-blocks on the guide rails until the product is visually positioned horizontally.

[0037] 5. Press down the second die, placing one hand lightly on the product's safety position behind the V-block. The boss of the second die will directly act on the needle roller bearing in the bracket mounting hole, causing it to move downwards along the journal until it reaches its position.

[0038] 6. Visually inspect to ensure the snap ring groove is exposed (pressed down to the bottom of the mold).

[0039] 7. Loosen the return valve (fine adjustment)

[0040] 8. Manually assemble the upper and lower retaining rings.

[0041] This device can greatly reduce labor intensity and increase assembly efficiency.

[0042] In this embodiment, as shown in the figure, the first mold is provided with a receiving groove 311, which is used to place the bearing. This ensures that the bearing will fall into the receiving groove after the bracket moves down.

[0043] In this embodiment, as shown in the figure, the second die is provided with a boss 321, which is positioned opposite to the bearing at the top of the cross pin. Pressing down the boss will cause the bearing to move downwards; this is during assembly, before the bearing is fully installed on the journal.

[0044] In this embodiment, as shown in the figure, the power source includes a drive rod, and the die is connected to the drive rod via a threaded connection. An external thread can be provided on the drive rod, and an internal thread on the die, to enable quick replacement.

[0045] In this embodiment, as shown in the figure, a slide block 20 is slidably mounted on the guide rail, and the support frame is mounted on the slide block. The position can be adjusted according to different shaft lengths.

[0046] In this embodiment, as shown in the figure, the mounting groove is a V-shaped groove. This makes the installation more stable.

[0047] In this embodiment, as shown in the figure, a screw 14 is provided on the base plate, and the screw contacts the bottom of the connecting seat 96 of the high-speed section. This supports the connecting seat and maintains the overall stability.

[0048] In this embodiment, as shown in the figure, the power source is a hydraulic cylinder or a pneumatic cylinder.

[0049] In this embodiment, as shown in the figure, the cross-section of the support column is circular.
