[0002] A shock absorber is mainly used to suppress the oscillation after the spring absorbs shock and the impact from the road surface. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] In the prior art, there is an auxiliary disassembly equipment for locomotive oil pressure shock absorbers disclosed in CN210334210U. This technology includes an auxiliary ring. An activity groove is opened inside the auxiliary ring. A nut positioning plate is installed inside the activity groove. A buffer spring is installed inside one end of the nut positioning plate. A connecting plate is welded to the lower surface of the auxiliary ring. A handle is arranged on one side of the auxiliary ring. The nut positioning plate is installed inside the activity groove through the buffer spring, so that the rivet nut is fixed at the central position of the auxiliary ring through the nut positioning plate and the buffer spring. At the same time, the auxiliary ring is connected to the handle through the connecting plate and a hand-tightening bolt. One end of the hand-tightening bolt penetrates through the connecting plate and is screwed into the inside of the handle. When the product is fixed by the rivet nut, it avoids the contact between the hand and the stamping equipment and increases the safety of rivet nut installation. However, there are the following problems in use:

[0004] When the above technology is used, it is connected to the stamping equipment through auxiliary parts, avoiding the hand approaching the stamping equipment when manually installing the nut, which increases the work safety of workers. However, the above technology cannot adapt to hex nuts of different sizes, has limited use, and cannot automatically remove the hex nut from the bolt, and manual force is required to remove the hex nut, resulting in waste of labor. Content of the Utility Model

The disc is provided with six sliding grooves. The second electric telescopic rod is used to push the slider to slide in the sliding groove. The slider is used to push the fixing piece to contract, so that the fixing piece clamps hexagonal nuts of different sizes. And between the disc and the mounting plate, there is a driving mechanism for driving the disc to rotate and a telescopic mechanism for pulling the fixing piece for fixing the hexagonal nut outward, facilitating the automatic screwing out of the hexagonal nut from the bolt.

[0008] Preferably, the telescopic mechanism includes an annular support, which is fixedly connected to the end of the first electric telescopic rod. The inner wall of the annular support is fixedly connected with a first rotating shaft, and the first rotating shaft is arranged between the four first electric telescopic rods.

[0009] Preferably, the driving mechanism includes a fixing plate, which is fixedly connected to the end of the first rotating shaft. The outer wall of the fixing plate is fixedly connected with a driving motor, and the driving end of the driving motor is fixedly connected with a second rotating shaft.

[0011] Preferably, the six sliding grooves are equidistantly distributed on the upper part of the disc, and the second electric telescopic rod is arranged in the sliding groove.

[0012] Preferably, the disc is rotatably connected with the first rotating shaft.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] In the utility model, the second electric telescopic rod is turned on, so that the second electric telescopic rod pushes the slider to move, thereby pushing the fixing piece to contract, making the six fixing pieces abut against the six faces of the hexagonal bolt to fix the hexagonal nut and adapting to hexagonal nuts of different sizes. Then the driving motor is turned on, so that the driving end of the driving motor drives the second rotating shaft to rotate, and then the driving gear drives the meshed toothed ring to rotate, so that the toothed ring drives the disc to rotate on the outer wall of the first rotating shaft.

The slider 9 is used to push the fixing piece 6 to contract, so that the inner wall of the fixing piece 6 is attached to the outer wall of the hexagon nut. Then, the fixing piece 6 is used to clamp hexagon nuts of different sizes. And a driving mechanism for driving the disc 5 to rotate and a telescopic mechanism for pulling the fixing piece 6 for fixing the hexagon nut outward are arranged between the disc 5 and the mounting plate 1, which is convenient for automatically screwing out the hexagon nut from the bolt;

[0025] Six sliding grooves 7 are equidistantly distributed on the upper part of the disc 5. The second electric telescopic rod 8 is arranged in the sliding groove 7, which is convenient for pushing the fixing piece 6 to clamp the hexagonal nut at the same time, so that the six fixing pieces 6 fix the hexagonal nut at the same time;

[0026] The disc 5 is rotationally connected to the first rotating shaft 4, which is convenient for screwing out the hexagonal bolt fixed by the fixing piece 6.

[0027] The function principle of the present utility model can be described by the following operation method:

[0028] First, turn on the second electric telescopic rod 8 to make the second electric telescopic rod 8 push the slider 9 to move, and then make the slider 9 move in the sliding groove 7, thereby pushing the fixing piece 6 to contract, so that the six fixing pieces 6 are in contact with the six surfaces of the hexagonal bolt. Then turn on the driving motor 13 to make the driving end of the driving motor 13 drive the second rotating shaft 12 to rotate, and then the second rotating shaft 12 drives the driving gear 11 to rotate, so that the driving gear 11 drives the meshed toothed ring 10 to rotate, thereby making the toothed ring 10 drive the disc 5 to rotate on the outer wall of the first rotating shaft 4. Then turn on the first electric telescopic rod 2 to make the first electric telescopic rod 2 drive the annular support 3 to move, and then the annular support 3 will pull the first rotating shaft 4 to move, so that the hexagonal nut fixed by the fixing piece 6 is screwed out under the drive of the driving motor 13, and the hexagonal nut is automatically screwed out by the tensile force of the annular support 3 on the first rotating shaft 4.
