Balance supporting auto-alignment device of machine tool

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.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a device for automatic alignment of vertical hydraulic balance supports of machine tools. Background technique [0002] At present, the vertical lifting motion box that is manufactured, sold and used in China is used for CNC machine tools or machining centers. In order to ensure the service life of the screw and the movement sensitivity of the machine tool, a hydraulic balance support mechanism will be used. Because the hydraulic balance support is Installed on two parts that move with each other, there will be assembly errors. There are the following defects: 1. The damping of the vertical movement of the machine tool is increased, which affects the accuracy of the machine tool; 2. The assembly cycle is increased; 3. The processing requirements for the shape and position tolerance of the parts are high, and the cost is increased. Contents of the inve...
