The lower part of the conical seat pull ring 8 and the conical seat mounting groove 4 form a second sealing space 11. The second oil passage 3 is connected to the second sealing space 11.

[0034] When the first oil passage 2 enters the first sealed space 10 through the oil inlet 7, the cone seat pull ring 8 moves downward, and the limiting steel ball 9 disengages from the limiting groove 6 and locks the tool holder pull pin 12; when the second oil passage 3 enters the second sealed space 11, the cone seat pull ring 8 moves upward, and the limiting steel ball 9 enters the limiting groove 6 under the thrust of the drive assembly, and the tool holder pull pin 12 disengages from the limiting steel ball 9.

The bulletproof pad 19 is fitted onto the bulletproof screw 17 and inserted into the central hollow structure of the pull ring from the lower end of the cone seat pull ring 8, and fixed to the cone seat center rod 15. The bulletproof pad 19 is stuck at the bottom of the limiting ring 13 to prevent the cone seat center rod 15 from being ejected by the compression spring 16. Finally, the fixing screw 14 is installed into the bottom of the cone seat pull ring 8.

[0038] More specifically, the compression spring 16 provides elastic force to the cone seat center rod 15, while the cone seat center rod 15 provides upward support force to the tool holder pull stud 12, and the fixing screw 14 is wrapped with PTFE tape to isolate the internal structure of the cone seat pull ring 8.

[0039] Preferably, a first sealing ring 20 and a second sealing ring 21 are provided between the cone seat fixture 1 and the lower cone seat 5.

[0044] Specifically, the support ring is used to support the sealing ring, ensuring that the sealing ring is not pressed by hydraulic oil when the cone seat pull ring 8 moves, and preventing the cone seat pull ring 8 from tilting when moving up and down, which would affect the accuracy of the steel ball limit.

[0045] Preferably, the cone seat fixture 1 has an adjustment ring 27 on its disc surface for adjusting the direction of the lower cone seat 5, and the adjustment ring 27 is coaxially arranged with the lower cone seat 5.

[0046] More preferably, the adjusting ring 27 is axially connected to the cone seat fixture 1 via an axial screw 28, and the adjusting ring 27 is radially connected to the lower cone seat 5 via a radial screw 29.

[0047] Specifically, the adjusting ring 27 is sleeved on the outside of the lower cone seat 5 and coaxially arranged with the lower cone seat 5. Then, it is set on the disc surface of the cone seat fixture 1 by an axial screw 28. The axial screw 28 is locked in with a little force, but not tightened, so that the radial screw 29 on the side can make fine adjustments to the adjusting ring 27. In this embodiment, there are 8 radial screws 29, which are evenly distributed to adjust the lower cone seat 5 in 8 directions.

[0048] More specifically, both the axial screw 28 and the radial screw 29 are internal hex socket head cap screws.

[0049] Preferably, there are four lower cone seats 5, which are located around the cone seat fixture 1 and are arranged symmetrically around the center.

[0050] Specifically, the lower conical seat 5 is mounted on the disc surface of the conical seat fixture 1 by a lower conical seat screw 30, wherein the lower conical seat screw 30 is an internal hexagon socket head cap screw, which is convenient for installation and disassembly.

[0051] More specifically, the oil inlets of the first oil passage 2 and the second oil passage 3 of the cone seat fixture 1 are provided with quick connectors 31, which are used to quickly supply oil to the cone seat fixture 1.

[0052] Preferably, the cone seat fixture 1 is provided with a pressure gauge 32 for monitoring the internal oil pressure of the cone seat fixture 1, and the pressure gauge 32 is located at the first oil passage 2 and / or the second oil passage 3.

[0053] Specifically, pressure gauge 32 constantly monitors whether the internal oil pressure of cone seat fixture 1 is within the standard requirements.

[0054] In specific implementation, when oil enters the first oil passage 2, the first sealed space 10 is filled with hydraulic oil, the conical seat pull ring 8 moves downward, and the upper limiting steel ball 9 disengages from the limiting groove 6 of the lower conical seat 5, thereby locking the tool holder pull pin 12 and ensuring a tight fit between the tool holder pull pin 12 and the upper conical seat. When oil enters the second oil passage 3, the second sealed space 11 is filled with hydraulic oil, the conical seat pull ring 8 moves upward, and the limiting steel ball 9 enters the limiting groove 6 of the lower conical seat 5 under the pushing force of the tool holder pull ring, thereby unlocking the tool holder pull pin 12 and allowing it to move freely with the upper conical seat. During this process, a coordinate measuring machine is used to measure the relative position and relative height of the tool holder pull pin 12 before and after movement to check whether the tool holder pull pin 12 meets the design requirements. During the testing process, multi-directional precision adjustments can be made using the adjusting ring 27, and multiple tests are performed after adjustment to ensure the accuracy of the test. The entire structure is easy to install and disassemble, greatly improving the testing speed.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
