Embodiment Construction
[0016] Such as figure 1 As shown, the beam hydraulic locking device with lateral positioning is composed of the same 9 hydraulic locks. The power module of the CNC system is connected to the AC bus inside the machine tool electric cabinet. It is characterized in that the hydraulic locks are installed on the The auxiliary parts used on the column and the beam are different. Among them, 8 vertical locking devices 1 are installed on the beam, and their positions are relative to the two sides of the column of the machine tool gantry frame. The ninth hydraulic locking device, that is, the lateral locking device 2, is installed on the convex surface of the right column with different accessories (as the main guide when the convex surface of the right column is operated), and is used for the connection between the beam and the right column. The main rail part is laterally positioned and locked, and it is used for lateral positioning when it is perpendicular to the column 4 and the cr...

Provided is a beam hydraulic locking device with lateral locating. Nine hydraulic locking devices adopt auxiliary parts of different structures, and a power module of a numerical control system is connected onto an alternating current bus bar in a machine tool electric cabinet. The beam hydraulic locking device with lateral locating is characterized in that eight vertical locking devices and the auxiliary parts of the same structure are installed on a beam at the positions corresponding to two sides of the two vertical column guide rails and used for vertically locating and locking the beam, the ninth hydraulic locking device is a lateral locking device which is installed on a convex edge face of a right vertical column by utilizing the different auxiliary parts and used for locating and locking the beam and the convex edge face of the right vertical column in the lateral direction, and inclination of the beam is avoided. The hydraulic locking devices are controlled by a hydraulic pipeline, the hydraulic system provides hydraulic oil for the locking devices to enable the locking devices to be loosened, and vertical movement of the beam is ensured. When the beam is fixed on the vertical column guide rails, oil in oil pumps of the locking devices are recovered, and the hydraulic locking devices are automatically locked. Only one hydraulic oil supplying pipeline is arranged, and the oil is provided to a lateral locking oil cylinder through a branch pipe on the right vertical column. The beam hydraulic locking device with lateral locating is simple to control and even in locking force distribution, and locking pressure of each locking device can achieve 120 kN.
Description
technical field [0001] The invention relates to mechanical equipment manufacturing, in particular to a positioning and locking device for lifting and lowering beams of vertical turning and milling centers, vertical lathes, gantry boring and milling centers and the like. Background technique [0002] At present, there are roughly two types of beam components used in processing equipment for vertical turning and milling centers, vertical lathes, and gantry boring and milling centers. It cannot be raised and lowered, and the machine tool does not have a W axis. The other is that the beam can be lifted up and down along the guide rails of the two columns. When the beam needs to be fixed at a certain position, the beam is locked on the column by an oil cylinder. The oil cylinder is controlled by two hydraulic oil lines, one is for locking the oil cylinder, and the other is for releasing the oil cylinder. When the beam needs to move up and down, the oil cylinder is released, and ...
