[0026] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0027] The technical solution of this utility model will be described in detail below through several specific embodiments. Unless otherwise stated, the raw materials and reagents used in the following embodiments are all commercially available products, or can be prepared by conventional methods in the art, and the instruments used in the embodiments are all commercially available.

[0028] Please see Figure 1 In the prior art, horizontal lathes include a spindle and a headstock, with the spindle extending from the headstock. When installing a horizontal lathe, the spindle accuracy needs to be adjusted. In order to improve the efficiency of spindle accuracy adjustment, this application provides a power device for adjusting the spindle of a horizontal lathe.

[0029] Please see Figure 2 The power unit for adjusting the spindle of a horizontal lathe provided by this utility model includes a drive unit 100, a first connecting sleeve 200, and a second connecting sleeve 300. The output shaft 110 of the drive unit 100 extends toward the spindle 10. The first connecting sleeve 200 is fixedly connected to both the spindle 10 and the output shaft 110. The second connecting sleeve 300 is sleeved around the spindle 10 and the first connecting sleeve 200, and is fixedly connected to both the housing of the drive unit 100 and the housing of the headstock 20. The drive unit 100 can be any device that transmits torque to the spindle 10; for example, the drive unit 100 is a geared motor. The power unit of this application transmits the torque of the output shaft 110 to the spindle 10 through the first connecting sleeve 200, driving the spindle 10 to rotate. It is easy to install, reduces the labor intensity of workers, and greatly improves work efficiency.

[0030] Please see Figures 2 to 5 In one embodiment, the first connecting sleeve 200 includes a top plate 210 and a first sidewall 220 fixedly disposed circumferentially along the top plate 210. The top plate 210 is fixedly connected to the main shaft 10, and the first sidewall 220 extends in a direction away from the main shaft 10. The first sidewall 220 forms a cavity 230 for placing the output shaft 110. The output shaft 110 extends into the cavity 230, abuts against the top plate 210, and is fixedly connected to the top plate 210. The cavity 230 can limit the output shaft 110, restricting the swing of the output shaft 110 in its radial direction, making the fit between the output shaft 110 and the first connecting sleeve 200 more stable, less prone to relative displacement, improving the reliability of the overall structure, and enhancing the bending and torsional resistance of the output shaft 110.

[0031] Please see Figures 3 to 5In one embodiment, the top plate 210 and the output shaft 110 are fixedly connected by screws. The output shaft 110 has a threaded hole that matches the screw, and the top plate 210 has a threaded through hole for the screw to pass through. Screw connection can provide precise and stable fixing force, ensuring tightness of the connection, and is convenient for installation and disassembly, facilitating maintenance. In this embodiment, the screw is a cylindrical head screw, and the top plate 210 has a groove 211 for placing the head of the cylindrical head screw. The groove 211 can increase the friction between the screw head and the top plate 210, thereby enhancing torque transmission capability and improving the stability and reliability of the connection. Placing the head of the cylindrical head screw in the groove 211 reduces the shape, weight, and manufacturing difficulty of the first connecting sleeve 200, facilitating installation and docking.

[0032] Please see Figure 6 In one embodiment, the first connecting sleeve 200 is fixedly connected to the spindle 10 by screws. Exemplarily, at least two threaded holes are provided on the end face of the spindle 10 along its circumference, symmetrically arranged around the axis of the spindle 10. A threaded through hole is provided at a corresponding position on the top plate 210. Screws pass through the threaded through holes on the top plate 210 and are threadedly connected to the spindle 10 to fix the top plate 210 to the spindle 10, thus achieving a fixed connection between the first connecting sleeve 200 and the spindle 10. The threaded holes on the spindle 10 are located near the outer edge of the spindle 10 to improve torque transmission efficiency. The number of threaded holes on the spindle 10 is not limited and can be adjusted according to actual needs. When there are multiple threaded holes on the spindle 10, the arc length between adjacent threaded holes is equal to ensure uniform force distribution on the spindle 10 and prevent shaking or vibration during rotation.

[0033] Please see Figure 2 and Figure 7In one embodiment, the second connecting sleeve 300 includes a first end ring 310, a second end ring 320, and a second sidewall 330 disposed between the first end ring 310 and the second end ring 320. One end of the second sidewall 330 is fixedly connected to the first end ring 310, and the other end of the second sidewall 330 is fixedly connected to the second end ring 320. The first end ring 310 is fixedly connected to the housing of the drive device 100, and the second end ring 320 is fixedly connected to the housing of the headboard box 20. By fixing the housing of the drive device 100 to the housing of the headboard box 20 through the second connecting sleeve 300, the rigidity of the entire structure can be enhanced, reducing the deformation and shaking of the housing caused by external forces or vibrations during use, thereby improving the stability and reliability of the equipment. At the same time, the second connecting sleeve 300 can provide additional protection for internal components, preventing the entry of external dust, water, oil, and other impurities, and also preventing internal components from being impacted and damaged. In this embodiment, the second sidewall 330 is provided with an opening 331 for observing the connection between the first connecting sleeve 200 and the output shaft 110 and the first output shaft 110 and the main shaft 10.

[0034] Please see Figure 2 and Figure 7 In one embodiment, the inner edge of the first end ring 310 extends radially along the second sidewall 330 to the inner side of the second sidewall 330, and the inner edge of the second end ring 320 extends radially along the second sidewall 330 to the inner side of the second sidewall 330. This arrangement can improve structural strength and stability, reduce deformation or displacement caused by external forces during use, enhance the reliability and stability of the second connecting sleeve 300, and optimize stress distribution. When the second connecting sleeve 300 is under stress, the portion located inside the second sidewall 330 can effectively disperse stress, avoid stress concentration, reduce the risk of fatigue failure of the second connecting sleeve 300 under high stress, and extend its service life.

[0035] Please see Figures 2 to 7 The installation process of the power unit used for the spindle debugging of the horizontal lathe in this application is as follows: a threaded hole is opened on the spindle 10, the threaded hole on the end face of the spindle 10 is adjusted to the horizontal direction, the spindle 10 is fixedly connected to the first connecting sleeve 200 by screws, one end of the second connecting sleeve 300 is fixedly connected to the housing of the drive device 100, and the other end of the second connecting sleeve 300 is fixedly connected to the housing of the headstock 20. Then, the first connecting sleeve 200 is fixedly connected to the output shaft 110 of the drive device 100 and the spindle 10 respectively through the opening 331 on the second connecting sleeve 300.
