[0042] Please refer to Figure 1 And 2 The utility model provides a machine tool body, including base 100, column assembly 200, first workstation 310 and second workstation 320.

[0043] The base 100 is located at the bottom and contacts the ground, for providing support for the base 100, column assembly 200, first workstation 310 and second workstation 320.

[0044] Please refer to Figure 2 And 3 The column assembly 200 is installed on the base 100, in the embodiment, the column assembly 200 includes three columns, three columns are spaced apart along the left-right direction of the base 100 and form two working channels on the base 100.

[0045] In order to facilitate the column to be installed on the base 100, the base 100 is provided with mounting boss 110;In the embodiment, the left, middle and right of the rear side of the base 100 along the left-right direction are provided with right mounting boss 110, and the number of mounting boss 110 is three, and the positions of the three mounting boss 110 correspond to the positions of the three columns respectively.

[0047] Please refer to Figure 1 and 2 , the specific connection mode between the column and the base 100 will be described below, the front side of the mounting step 203 of the column is connected with the mounting boss 110 on the base 100 through the first locking fastener 120, and the first locking fastener 120 penetrates the mounting boss 110; the rear side of the mounting step 203 of the column is connected with the mounting boss 110 on the base 100 through the second locking fastener 130, and the number of the second locking fastener 130 is greater than or equal to the number of the first locking fastener 120, and the second locking fastener 130 penetrates the mounting boss 110. Since the spindle box is mounted on the front side of the cross beam, under the action of the gravity of the spindle box, the cross beam will have a tendency to fall forward; the number of bolts behind the column is greater than that in front of the column, so that the cross beam is prevented from falling forward and is more stable, maintaining the balance of the cross beam front and rear.

[0048] Please refer to Figure 1 , 2 and 5, the specific structure of the auxiliary reinforcing fastener 140 will be described in detail below, the auxiliary reinforcing fastener 140 includes a first connecting plate 141, a second connecting plate 142, and a reinforcing plate 143 connected with the first connecting plate 141 and the second connecting plate 142, one of the first connecting plate 141 and the second connecting plate 142 is connected with the mounting boss 110 on the base 100, and one of the first connecting plate 141 and the second connecting plate 142 is connected with the mounting step 203 of the column.
