[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a shaft head disassembly and assembly auxiliary device, including a movable seat 1, a lifting mechanism 2 provided on the top of the movable seat 1, and a locking mechanism 3 provided on the top of the lifting mechanism 2.

[0031] The lifting mechanism 2 includes multiple slide rods 201 that are evenly distributed and symmetrically installed on the top of the movable seat 1. A lifting plate 202 is provided on the outer surface of the slide rods 201. A limit plate 203 is installed at the bottom center of the lifting plate 202. A T-shaped slider 208 is movably installed inside the limit plate 203. A connecting rod 207 is provided at the bottom of the T-shaped slider 208 through a hinge seat.

[0032] Specifically, the top of the lifting plate 202 has evenly distributed and symmetrically arranged through holes that are adapted to multiple sliding rods 201. The lifting plate 202 is slidably connected to the outside of the multiple sliding rods 201 through the through holes. The side of the limiting plate 203 has a T-shaped groove adapted to a T-shaped slider 208. The T-shaped slider 208 is slidably connected inside the T-shaped groove. Under the action of the multiple sliding rods 201, the stability of the lifting plate 202 during its up and down movement is ensured. When the connecting rod 207 flips, the T-shaped slider 208 moves in the groove of the limiting plate 203, which can raise or lower the lifting plate 202.

[0033] Specifically, the lifting mechanism 2 also includes upright plates 204 symmetrically installed at the top center of the movable seat 1. A first rotating shaft 206 is movably installed on one side of the two upright plates 204 through a bearing seat. One end of the first rotating shaft 206 extends to one side of the upright plate 204 and is provided with a first motor 205. A fixing hole adapted to the first rotating shaft 206 is opened on one side of the connecting rod 207. One end of the connecting rod 207 is fixedly installed on the outside of the first rotating shaft 206 through the fixing hole. Under the action of the two upright plates 204, the first rotating shaft 206 rotates smoothly, thereby driving the connecting rod 207 to rotate around the first rotating shaft 206, so that the other end of the connecting rod 207 drives the T-shaped slider 208 to move in the limiting plate 203.

[0034] Furthermore, the operation of the first motor 205 is controlled. The output end of the first motor 205 drives the first rotating shaft 206 to rotate on the opposite side of the two upright plates 204, thereby driving the connecting rod 207 to rotate around the first rotating shaft 206. This causes the connecting rod 207 to drive the T-shaped slider 208 to move within the limiting plate 203. During the movement of the T-shaped slider 208 driven by the connecting rod 207, the connecting rod 207 moves in an arc around the first rotating shaft 206, thereby lifting the limiting plate 203 upward. Under the action of multiple sliding rods 201, the limiting plate 203 lifts the lifting plate 202 to a certain height, and then lifts the snap-fit ​​mechanism 3 located on the top of the lifting plate 202 to match the height of the disassembly and assembly shaft head.

[0035] Example 2

[0036] Reference Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment. The snap-fit ​​mechanism 3 includes a fixed seat 301 fixedly installed on the top of the lifting plate 202. A second rotating shaft 303 is movably installed on one side of the fixed seat 301. A receiving block 304 is provided on one side of the second rotating shaft 303. A plug-in post 305 is movably inserted into the receiving block 304. A wrench 306 is symmetrically arranged on one side of the plug-in post 305. A stop post 307 adapted to the wrench 306 is symmetrically installed on one side of the plug-in post 305.

[0037] Specifically, the receiving block 304 has a slot inside that is adapted to the insertion post 305. The insertion post 305 is movably inserted into the slot. The second rotating shaft 303 is movably installed inside the fixed base 301 through a bearing. One end of the second rotating shaft 303 extends to one side of the fixed base 301 and is equipped with a second motor 302. When the second rotating shaft 303 is driven to rotate, it can drive the receiving block 304 to rotate. The insertion post 305 drives the two stop posts 307 to rotate. Under the action of the two stop posts 307, a certain rotational force is applied to the wrench 306, and the nut placed inside the wrench 306 is disassembled and assembled.

[0038] Specifically, the receiving block 304 has a locking block 308 inside, a pull rod 309 is installed at the center of one side of the locking block 308, a spring 310 is installed on one side of the locking block 308, and a slot adapted to the locking block 308 is opened on one side of the insertion post 305. The locking block 308 is movably inserted into the slot. Under the action of the locking block 308, after the insertion post 305 is inserted into the receiving block 304, the locking block 308 is pushed into the slot of the insertion post 305 by the spring 310, fixing the insertion post 305 in the receiving block 304, and also facilitating the quick replacement of the insertion post 305.

[0039] Specifically, the receiving block 304 has a square groove inside that is adapted to the locking block 308. The locking block 308 is slidably connected inside the square groove. The spring 310 is located outside the pull rod 309. The receiving block 304 has a round hole on one side that is adapted to the pull rod 309 and is connected to the square groove. The pull rod 309 is slidably connected inside the round hole. Under the action of the spring 310, a pushing force is applied to the locking block 308, so that the locking block 308 fixes the plug-in post 305 in the receiving block 304. When the pull rod 309 is pulled outward, the locking block 308 is removed from the slot of the plug-in post 305, and the plug-in post 305 adapted to the wrench 306 can be replaced.

[0040] Furthermore, the wrench 306 is secured to the nut on the shaft head. The movable seat 1 is controlled to move the insertion pin 305, causing the stop pin 307 to engage with the wrench 306. The second motor 302 is then controlled to rotate the second shaft 303, which in turn rotates the receiving block 304. The receiving block 304 then rotates the insertion pin 305. Through the action of the two stop pins 307, the wrench 306 rotates, thus disassembling the nut. To install, simply rotate the plug 305 in the opposite direction, pull the lever 309 outward, pull the locking block 308 out of the slot of the plug 305, then pull the plug 305 out of the receiving block 304, replace it with a plug 305 that is compatible with the wrench 306, insert the plug 305 into the receiving block 304, and under the action of the spring 310, push the locking block 308 into the slot of the plug 305 to complete the installation and removal of the plug 305.

[0041] Working principle: The device is connected to an external power domain controller via a wiring harness. The wrench 306 is engaged with the nut on the shaft head. The control movable seat 1 moves the plug pin 305, causing the stop pin 307 to engage with the wrench 306. The operation of the second motor 302 is controlled, which drives the second rotating shaft 303 to rotate. The second rotating shaft 303 drives the receiving block 304 to rotate, and the receiving block 304 drives the plug pin 305 to rotate. Through the action of the two stop pins 307... Rotate the wrench 306 to remove the nut. For installation, simply rotate the connector 305 in the opposite direction. When removing or installing nut caps of different sizes, pull the lever 309 outwards to pull the retaining block 308 out of the connector 305's slot. Then pull the connector 305 out of the receiving block 304, replace it with a connector 305 compatible with the wrench 306, and insert the connector 305 into the receiving block 304. (The spring 31...) Under the action of 0, the locking block 308 is pushed into the slot of the plug-in post 305 to complete the replacement of the plug-in post 305. The matching wrench 306 is then locked onto the shaft head nut. The principle is the same as above, and the shaft head is disassembled and assembled. When encountering shaft heads of different heights, the operation of the first motor 205 is controlled. The output end of the first motor 205 drives the first rotating shaft 206 to rotate on the opposite side of the two vertical plates 204, thereby driving the connecting rod 207 to rotate around the first rotating shaft 206. This causes the connecting rod 207 to drive the T-shaped slider 208 to move in the limiting plate 203. During the movement of the T-shaped slider 208 driven by the connecting rod 207, the connecting rod 207 moves in an arc around the first rotating shaft 206, thereby lifting the limiting plate 203 upward. Under the action of multiple sliding rods 201, the limiting plate 203 lifts the lifting plate 202 to a certain height, and the stop post 307 placed on the top of the lifting plate 202 is lifted to the height suitable for disassembling and assembling the shaft head.

[0042] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
