In addition, through internal and external spray cooling, sufficient cooling of the cutting area is guaranteed, and the workpiece temperature is fully controlled to remain relatively stable. The above are all existing technologies, so this application is not described in detail.

[0023] The positioning cylinder 105 is fixedly connected to the support base 101 and is threadedly connected to the pressure rod 103. The driving assembly is arranged on the support base 101, the limiting assembly is arranged on the pressure rod 103, and the auxiliary assembly is arranged on the support base 101.

The two pressure rods 103 are respectively located in the two positioning cylinders 105, and the outer surface of the pressure rod 103 is threadedly connected to the inner surface of the positioning cylinder 105. There are two groups of driving assemblies, which are respectively arranged on both sides of the lower surface of the support base 101. When the driving assembly is started, it can drive the pressure rod 103 to move vertically inside the positioning cylinder 105, so as to adjust the height of the pressure rod 103. The height of the pressing plate 104 is adjusted so that the pressing rod 103 and the positioning cylinder 105 cooperate with each other, and the sleeve parts of different heights can be clamped and fixed. The limiting component is arranged at the bottom end of the pressing rod 103, and the limiting component is located in the positioning cylinder 105.

In the process of clamping and fixing the thin-walled sleeve, by starting the driving component, the driving component can drive the pressing rod 103 to move vertically inside the positioning cylinder 105 under threaded drive, so that the height of the pressing rod 103 changes, thereby changing the height of the pressing plate 104, and then making it easy to adjust the total length of the pressing rod 103 and the positioning cylinder 105, so that the equipment can adapt to sleeve parts of different heights and is easy to use.

[0024] Secondly, the driving motor 106 is fixedly connected to the supporting base 101 and is located on one side of the supporting base 101; the driving rod 107 is rotatably connected to the supporting base 101 and is located on one side of the supporting base 101, and the driving rod 107 is fixedly connected to the output shaft of the driving motor 106; the driving block 108 is fixedly connected to the driving rod 107 and is threadedly connected to the pressure rod 103.

The driving block 108 is located inside the pressure rod 103. The diameter of the driving block 108 is equal to the inner diameter of the pressure rod 103. The outer surface of the driving block 108 has an outer thread. The inner surface of the pressure rod 103 has an inner thread that matches the outer thread. The threaded connection direction of the driving block 108 and the pressure rod 103 is the same as the threaded connection direction of the pressure rod 103 and the positioning cylinder 105. In the opposite direction, when the driving motor 106 is started, it can drive the driving rod 107 to drive the driving block 108 to rotate in the pressure rod 103, so that the pressure rod 103 is driven by the thread of the driving block 108 to move vertically in the positioning cylinder 105 along the direction of the positioning cylinder 105, thereby changing the total height of the positioning cylinder 105 and the pressure rod 103, so that the height of the pressure plate 104 can adapt to sleeve parts of different heights, without the need to replace equipment of different sizes, and the operation is simple.

The inner diameter of the limiting ring 109 is equal to the diameter of the driving rod 107, and the inner diameter of the limiting ring 109 is smaller than the diameter of the driving block 108, so that the bottom end of the pressure rod 103 moves to When the pressure rod 103 is at the driving block 108, the limiting action of the limiting ring 109 can prevent the pressure rod 103 from separating from the driving block 108. The upper surface of the limiting ring 109 is fixed with the protective pad 110. The protective pad 110 is made of soft rubber material, has the characteristics of anti-slip and wear-resistant, and has good toughness. It can be elastically deformed by extrusion. The setting of the protective pad 110 enables the limiting ring 109 to contact the driving block 108 through the protective pad 110 when it moves to the bottom of the driving block 108, thereby protecting the limiting ring 109 and reducing the wear on the limiting ring 109.
