A coupling 15 is installed between the first ball screw 16 and the first handle 13. Second linear guides 17 are installed at the front and rear ends of the top of the base 6. A limiter 18 is provided on the side of the second linear guide 17 close to the outside;
[0024] The first ball screw 16 is connected to the first sliding seat 19 by threaded engagement. The threads on both sides of the first ball screw 16 are opposite to each other. The cylinder barrel 7 is disposed between the V-shaped positioning blocks 14. The first handle 13 is mounted on the right side of the first ball screw 16 via a coupling 15.
[0025] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, by shaking the first handle 13, the first handle 13 drives the first ball screw 16 to rotate through the coupling 15. Since the threads at both ends of the first sliding seat 19 are matched in opposite directions, the rotation of the first ball screw 16 can drive the V-shaped positioning block 14 to move inward or outward in the Y-axis direction at the same time, thereby realizing the clamping and loosening functions of the cylinder barrel 7 and the cooling cylinder barrel 8. The second linear guide 17 is connected to the V-shaped positioning block 14 to ensure the accuracy of transmission, and a limiter 18 is designed. By adjusting the position of the limiter 18, the clamping spacing of the V-shaped positioning block 14 is changed, which is compatible with the clamping of cylinder barrels 7 and cooling cylinder barrel 8 of different outer diameters. The cylinder barrel 7 is in the Y-axis and Z-axis position to ensure that the installation position is in the center. The design is flexible and versatile. It can be assembled for cylinder barrels 7 and cooling cylinder barrel 8 of various specifications and sizes, realizing multi-purpose use of one machine, saving manufacturing cost and storage space.

[0028] Working principle: When the utility model is in use, the first handle 13 is shaken, and the first handle 13 drives the first ball screw 16 to rotate through the coupling 15. Since the threads at both ends of the first sliding seat 19 are matched in opposite directions, the rotation of the first ball screw 16 can drive the V-shaped positioning block 14 to move inward or outward in the Y-axis direction at the same time, thereby realizing the clamping and loosening functions of the cylinder barrel 7 and the cooling cylinder barrel 8. The second linear guide 17 is connected to the V-shaped positioning block 14 to ensure the accuracy of transmission, and a limiter 18 is designed. By adjusting the position of the limiter 18, the clamping spacing of the V-shaped positioning block 14 is changed, which is compatible with the clamping of cylinder barrels 7 and cooling cylinder barrels 8 with different outer diameters. The cylinder barrel 7 is in the Y-axis and Z-axis position to ensure that the installation position is in the center. The design is flexible and has strong versatility. Cylinder barrels 7 and cooling barrels 8 of various specifications and sizes can be assembled to achieve multi-purpose use of one machine, saving manufacturing cost and storage space. After limiting the cylinder barrels 7 and cooling barrels 8, the second handle 23 is shaken to drive the second ball screw 25 to rotate, and the second sliding seat 24 with threaded engagement drives the top shaft 21 to move forward in the X-axis direction. The top shaft 21 slowly presses the cylinder barrel 7 and the cooling barrel into the end face of the hydraulic cylinder 4 to achieve press-fitting. The cylinder barrel press-fitting fixture 2 can move freely in the Y-axis direction through the first linear guide rail 5, leaving space for loading and unloading, preventing the cylinder barrel press-fitting fixture 2 from affecting loading and unloading. Assembly using this device can replace high-intensity manual assembly, greatly reduce labor load, and improve production efficiency.
