[0010] like Figure 1 As shown, a structure of a dovetail guide of a crossbeam and a column adopting an inclined iron cylinder positioning mechanism comprises a crossbeam 1, a column 2, a clamping lever 3, a dovetail guide rail 4, a crossbeam clamping hydraulic cylinder 5, a spherical pressure block 6, an inclined iron 7 and a clamping cylinder 8. The crossbeam 1 is provided with a dovetail guide rail 4, and the column 2 is installed in the dovetail guide rail 4. The dovetail guide rail 4 cooperates with the joint surface of the column 2 to form a dovetail guide structure; a crossbeam clamping hydraulic cylinder 5 is installed on the right side of the guide rail connection between the crossbeam 1 and the column 2, and the piston end of the crossbeam clamping hydraulic cylinder 5 is connected to the right side of the column 2. An oblique iron 7 is provided in between, and the piston end of the crossbeam clamping hydraulic cylinder 5 and the oblique iron 7 adopt a combined clamping form to clamp the right side of the column 2; a clamping cylinder 8 is provided on the top of the left side of the crossbeam 1, and on the left side of the clamping cylinder 8, a clamping lever 3 is hinged on the crossbeam 1, and the middle position of the clamping lever 3 is the hinge point. The piston end of the clamping cylinder 8 is hinged to one end of the clamping lever 3, and a spherical pressure block 6 is provided between the other end of the clamping cylinder 8 and the left side of the column 2, and the clamping lever 3 clamps the left side of the column 2 by squeezing the spherical pressure block 6.
[0011] In the CNC single-column vertical lathe, the crossbeam 1 is the carrier of the tool holder and makes vertical movement on the column 2. The crossbeam 1 drives the tool holder to make linear movement to process the workpiece. A dovetail guide structure is adopted on the mating surface of the crossbeam 1 and the column 2; a crossbeam clamping hydraulic cylinder 5 is installed at the guide rails of the crossbeam 1 and the column 2. The crossbeam clamping hydraulic cylinder 5 can select the strengthening or relaxation of the clamping force by controlling the change of oil pressure. The strengthening of the clamping force makes the crossbeam 1 and the column 2 clamped, and the crossbeam 1 is fixed. The relaxation of the clamping force makes the crossbeam 1 move up and down linearly on the column 2; the left side of the crossbeam 1 is the clamping cylinder 8 that pushes one end of the clamping lever 3, with the hinge point of the crossbeam 1 and the clamping lever 3 as the axis, and the other end of the clamping lever 3 squeezes the spherical pressure block 6 on the left side of the crossbeam 1, so that the left side of the crossbeam 1 can clamp the column 2, and the right side of the crossbeam 1 is the crossbeam clamping hydraulic cylinder 5 that clamps through the inclined iron 7, so that the right side of the crossbeam 1 can clamp the column 2.
[0012] The crossbeam 1 and the column 2 adopt dovetail guide to increase the contact area between the two components and improve the guiding accuracy; the crossbeam 1 is positioned and clamped by the crossbeam clamping hydraulic cylinder 5 and the clamping cylinder 8 on the left and right sides of the crossbeam 1, so that the clamping or loosening commands between the crossbeam 1 and the column 2 can be completed quickly and safely.
