The plurality of loading seats 8 fixedly arranged on the top receiving plate 7 and close to the second pre-installed grooves 50 are used to load the plug-in sleeve 9. The handle screw 10 plugged into the loading seat 8 is used to adjust the position of the sliding seat 12 in the loading seat 8. The movement trajectory of the sliding seat 12 is a linear motion. The sliding seat 12 sleeved on the handle screw 10 is used to fix the loading mechanism. The loading mechanism set on the sliding seat 12 is used to load and fix the cylinder 15.

The limiting mechanism is also arranged on the inner side of the loading seat 8 to limit the sliding seat 12, so that the sliding of the sliding seat 12 is more stable. When the handle screw 10 is rotated, the handle screw 10 drives the sliding seat 12 to move linearly on the inner side of the loading seat 8. The sliding seat 12 drives the loading mechanism to move together, and the loading mechanism drives the cylinder 15 to move together, so that the device can make the cylindrical rubber block 17 closer to the hydraulic shaft to facilitate the subsequent clamping of the cylindrical rubber block 17.

The rotating disk 22 and the rotating seat 23 are rotatably connected to facilitate the indexing rotation of the hydraulic shaft. The travel groove 24 opened on the inner side of the rotating seat 23 is used as the installation space of the middle clamping block 25. The middle clamping block 25 can be contracted or extended on the inner side of the travel groove 24, so as to realize the release or clamping of the hydraulic shaft. The middle clamping mechanism arranged on the inner side is used to clamp the middle part of the hydraulic shaft. The indexing rod 34 inserted on the middle receiving plate 5 is used to load the top turntable 35, and when the top turntable 35 is loaded, it can be driven to rotate, so that the hydraulic shaft can complete the indexing rotation during the processing.

The first toggle rod 36 installed on the top turntable 35 is used to control the rotating seat 23 to index and rotate. The second toggle rod 37 installed on the top turntable 35 is used to control the rotating seat 23 to index and rotate. After the rotating seat 23 rotates, it is used to limit the position of the rotating seat 23 to prevent the rotating seat 23 from rotating beyond the range. The bearing 41 provided at the bottom of the indexing rod 34 is used to receive the bottom receiving plate 2 and the indexing rod 34. The indexing rod 34 can rotate on the bottom receiving plate 2. The indexing plate 38 fixedly provided above the bearing 41 through the indexing rod 34 is used to limit the rotation of the indexing rod 34. The rotor 44 fixedly provided on the indexing shaft 43 is used to fit with the indexing plate 38. In this embodiment, the rotation angle of the indexing plate 38 is set to 90 degrees each time. The motor 42 fixedly arranged on the connecting plate 2 and close to the bearing 41 is used to load and drive the indexing shaft 43 to rotate. The indexing shaft 43 fixedly installed on the motor 42 is used to cooperate with the indexing plate 38 to complete a 90-degree angle rotation, and the indexing plate 38 is limited after the rotation, so that it can only rotate 90 degrees each time. The push seat 46 fixedly arranged on the indexing shaft 43 and located below the rotor 44 is driven by the motor 42 to rotate continuously, and the indexing plate 38 will be driven to complete a 90-degree rotation only when the push rod 47 is in contact with the indexing plate 38.

[0045] During the process of processing the hydraulic shaft, when the end face of the hydraulic shaft needs to be processed, the bottom holding mechanism cooperates with the middle clamping mechanism to stably clamp the hydraulic shaft. During this process, the end face of the hydraulic shaft can be processed, and during this process, the hydraulic shaft can be indexed and rotated by the indexing mechanism, so that the staff can process the end face of the hydraulic shaft in multiple directions, and the processing is more convenient.

[0046] When the side wall of the hydraulic shaft needs to be processed, the bottom of the hydraulic shaft is supported against the middle clamping mechanism through the bottom supporting mechanism, and in this process, the top receiving plate 7 is driven to move downward, so that the top clamping mechanism clamps the top of the hydraulic shaft, and then the hydraulic shaft is clamped by the top clamping mechanism and the middle clamping mechanism, and the middle part of the hydraulic shaft is exposed to facilitate the processing of its side wall. At this time, the hydraulic shaft can be driven to rotate in an indexing manner through the indexing mechanism, so that the staff can process the side wall of the hydraulic shaft in multiple directions, which makes the processing more convenient and the processing efficiency higher.
