Abstract

The invention discloses a balance supporting auto-alignment device of a machine tool and relates to the technical field of machinery manufacturing. The balance supporting auto-alignment device of the machine tool comprises a supporting seat. One end of the supporting seat is connected with a lifting main shaft box, and the other end of the supporting seat is connected with a boss of the end portion of a piston rod. An upper auto-alignment spherical gasket and a lower auto-alignment spherical gasket are sleeved on the connecting position between the boss of the end portion of the piston rod and the supporting seat. The plane of the lower auto-alignment spherical gasket is contacted with the supporting seat. The convex spherical surface of the lower auto-alignment spherical gasket is contacted with concave spherical surface of the upper auto-alignment spherical gasket. The upper auto-alignment spherical gasket sleeved on the end of the boss of the piston rod is locked through a locking nut. The balance supporting auto-alignment device of the machine tool can solve the problems that the precision of the machine tool is not good due to the large geometric tolerance after a liquid-level balance mechanism is installed on a machine tool, the assembly period is prolonged and the production cost is increased.

[0012] The present invention will be described in further detail below in conjunction with the drawings:

[0013] figure 1 Automatic aligning device for machine tool balance support; includes a support base 2; one end of the support base 2 is connected to the machine lifting headstock 1 through bolts and pins, and the other end is connected to the boss at the end of the piston rod 6 in the cylinder, The cylinder body of the oil cylinder is fixedly installed on the sliding seat of the lifting headstock 1; the upper self-aligning spherical washer 4 and the lower self-aligning spherical washer are sleeved at the connection between the boss at the end of the piston rod 6 and the supporting seat 2 5; One side of the upper self-aligning spherical washer 4 is a plane, the other side is a convex spherical surface, one side of the lower self-aligning spherical washer 5 is a plane, and the other side is a concave spherical surface; the lower self-aligning spherical washer 5 The plane is in contact with the supporting seat 2, the convex spherical surface of the lower self-aligning spherical washer 5 is in contact with the concave spherical surface of the upper self-aligning spherical washer 4; the upper self-aligning spherical washer 4 sleeved on the boss end of the piston rod 6 is secured by a lock nut 3 Lock tightly.

[0014] When the machine tool lifting headstock 1 moves up and down, the piston rod 6 supports the support base 2 connected to the lifting headstock 1 through the upper self-aligning spherical pad 4 and the lower self-aligning spherical washer 5, and the hydraulic balance supports are installed in two In the relative moving parts, when there is an error, the upper self-aligning spherical washer 4 and the lower self-aligning spherical washer 5 are automatically aligned, which is equivalent to a mechanical movable joint, which keeps the linear motion with the lifting headstock 1 at any time during the up and down movement. Dynamic verticality, to solve the problem of automatic alignment of the spherical washer when the hydraulic balance support is installed on the two relative moving parts, and the purpose of reducing the damage to the accuracy of the machine tool.
