[0031] Please see Figure 1 and Figure 2 In a first aspect, an embodiment of the present utility model provides a base assembly. The base assembly includes a base body 100, a first reduction mechanism 200, a second reduction mechanism 300, a main shaft 400, a driving member 500 and an adjusting mechanism 600. The driving member 500 is mounted on the base body 100 through the first reduction mechanism 200, the main shaft 400 is passed through the base body 100, the working end of the main shaft 400 is located outside the base body 100, the second reduction mechanism 300 is arranged between the first reduction mechanism 200 and the main shaft 400, and the second reduction mechanism 300 is arranged inside the base body 100. The driving member 500 is transmission-connected to the main shaft 400 through the first reduction mechanism 200 and the second reduction mechanism 300. The adjusting mechanism 600 is arranged between the base body 100 and the first reduction mechanism 200, and the first reduction mechanism 200 adjusts its position relative to the main shaft 400 through the adjusting mechanism 600.

[0032] By providing a first reduction mechanism 200 and a second reduction mechanism 300 between the drive member 500 and the spindle 400, the torque of the spindle 400 can be increased through a two-stage reduction mechanism. Heavy cutting machining requires a higher torque on the spindle 400. Therefore, providing a two-stage reduction mechanism to increase the torque of the spindle 400 makes the machining center suitable for heavy cutting applications. The adjustment mechanism 600 facilitates adjustment of the position of the first reduction mechanism 200 and the drive member 500 relative to the base body 100.

The first reduction mechanism 200 includes a power input shaft 210 and a power output shaft 220. The power input shaft 210 is in driving connection with the driving member 500, and the power output shaft 220 is in driving connection with the second reduction mechanism 300. The transmission ratio between the power input shaft 210 and the power output shaft 220 is greater than 1. Specifically, the first reduction mechanism 200 also includes a fixing base 230 for mounting the power input shaft 210 and the power output shaft 220.

[0034] Please see Figure 2 The positional relationship between the first reduction mechanism 200, the driving member 500, and the base body 100 is as follows: the driving member 500 is mounted on the base body 100 via the first reduction mechanism 200. The direct connection between the driving member 500 and the first reduction mechanism 200 facilitates installation and removal of the driving member 500 and the first reduction mechanism 200.

[0035] Please see Figure 2 and Figure 4 The positional relationship between the second deceleration mechanism 300, the main shaft 400 and the base body 100 is as follows: the second deceleration mechanism 300 is a belt transmission mechanism, the second deceleration mechanism 300 is arranged between the first deceleration mechanism 200 and the main shaft 400, and the second deceleration mechanism 300 is arranged in the base body 100.

[0036] Please see Figure 4 The detailed structure of the second reduction mechanism 300 is described below. In some embodiments, the second reduction mechanism 300 includes a first transmission wheel 310, a second transmission wheel 320, and a transmission belt 330. The first transmission wheel 310 and the second transmission wheel 320 are connected in transmission via the transmission belt 330.

The first transmission wheel 310 is connected in transmission with the first reduction mechanism 200, and the second transmission wheel 320 is connected in transmission with the main shaft 400. At least two transmission belts 330 are provided, and the first transmission wheel 310 and the second transmission wheel 320 are connected in transmission via two parallel transmission belts 330. Compared to a solution with only one transmission belt 330, the provision of two parallel transmission belts 330 can further improve the transmission stability between the first transmission wheel 310 and the second transmission wheel 320.

The first reduction mechanism 200 and a portion of the driver 500 are housed within the mounting platform 101, and the working end of the spindle 400 is located above the machining groove 102. The provision of the mounting platform 101 reduces the space occupied by the driver 500 and the first reduction mechanism 200. Furthermore, a portion of the spindle 400 is located within the base body 100, thereby facilitating transmission connection between the first reduction mechanism 200, the second reduction mechanism 300, and the spindle 400.

[0038] Please see Figure 1 and 2 , the detailed structure of the machining groove 102 is introduced below: In some embodiments, the machining groove 102 includes a first slope 110, a chip removal channel 120 and a second slope 130. The chip removal channel 120 is arranged between the first slope 110 and the second slope 130, and the low positions of the first slope 110 and the second slope 130 are connected to the chip removal channel 120. By setting the first slope 110 and the second slope 130, the chips generated by machining can be conveniently discharged into the chip removal channel 120 through the first slope 110 and the second slope 130, avoiding excessive chips from remaining on the base body 100, thereby speeding up the chip removal efficiency. The spindle 400 is installed on the first slope 110 close to the chip removal channel 120, which can quickly remove chips. Please refer to Figure 2 In some embodiments, to facilitate installation of a column on the base body 100, a column mounting portion 105 is further provided above the base body 100, and the mounting recess 101 is located on the side of the machining groove 102 near the first slope 110. The column mounting portion 105 is located on the side of the machining groove 102 near the chip removal channel 120, thereby fully utilizing the space on the surface of the base body 100.

The adjustment member 620 is disposed between the mounting seat 610 and the mounting plate 630 and is used to adjust the position of the mounting plate 630 relative to the mounting recess 101. The adjustment accuracy of the adjustment member 620 can be adjusted according to actual conditions. For example, the adjustment member 620 is a bolt with an adjustment accuracy of one pitch length. Different types of bolts can be replaced to adjust the adjustment accuracy.

[0041] After the adjustment mechanism 600 is adjusted to the correct position, the mounting plate 630 needs to be locked with the base body 100. Figure 2 The following describes how to secure the mounting plate 630 to the base body 100: The base assembly also includes a fastener 700. The mounting plate 630 has a waist-shaped hole 631 extending along the direction of the adjustment member 620, and the mounting recess 101 has a corresponding mating portion. For example, the fastener 700 can be a bolt. The fastener 700 securely connects the mounting plate 630 to the base body 100 through the waist-shaped hole 631 and the mating portion, thereby facilitating the securement of the mounting plate 630 to the base body 100.
