Abstract
The utility model discloses a machine tool cross beam locking device which comprises a flange plate, a disc spring, a piston, a pipe connector, a pressure plate, a cross beam, a bolt and an upright post, wherein the upright post is arranged on the right side of the cross beam, the upper end surface of the cross beam is in planar connection with the guide rail surface of the upright post, the right end of the pressure plate presses the connection part of the two plane surfaces and is fixed through bolts; and a hydraulic loosening and spring locking mechanism composed of the flange plate, the disc spring, the piston and the pipe connector is mounted between the left end of the cross beam and the pressure plate. The machine tool cross beam locking device provided by the utility model has the benefits as follows: the device achieves the purpose of pressure plate mechanical force increasing and locking through the structural style of the locking and the hydraulic loosening of the disc spring. The device increases the locking force of the pressure plate in a way of cross beam mechanical force increasing and locking, and the produced locking force is more than four times of the pressure of the disc spring.
Description
Technical field
The utility model relates to a kind of machine tool beam locking device, belongs to the Machining Technology field.
Background technology
Present heavy vertical lathe crossbeam mostly adopts skewback wedging pressing plate to come as locking device, and the piston rod by hydraulic jack pulls skewback.The shortcoming that arranges like this is that number of spare parts is more, structure is more complicated; and hydraulic jack needs to be connected with hydraulic oil all the time in the course of work of lathe; not only easily cause Hydraulic System Fever excessive; but also easily cause hydraulic system generation seepage, often can cause crossbeam can not normally lock phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of machine tool beam locking device, and this device has safe and reliable advantage.
The technical solution of the utility model is: this device is made of ring flange, disk spring, piston, pipe joint, pressing plate, crossbeam, screw, column; Column is arranged on the right side of crossbeam, and the guide pass plane of the upper surface of crossbeam and column is connected, and the right-hand member of pressing plate is pressed in the joining place on two planes, and is fixed by screw; Be equipped with between the left end of crossbeam and pressing plate and connect by ring flange, disk spring, piston and pipe that the hydraulic pressure that consists of loosens, the spring retaining mechanism.
The beneficial effects of the utility model are: this device by the version that disk spring is locked, hydraulic pressure loosens, has been realized the tight purpose of pressing plate machinery force-increasing lock by lever principle.This device has strengthened the coupling mechanism force of pressing plate by the tight mode of crossbeam machinery force-increasing lock, its coupling mechanism force that produces is more than four times of disk spring pressure, has solved well dangerous, insecure problem in traditional machine tool crossbeam hydraulic jack locking mechanism.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Number in the figure:
1, ring flange 2, disk spring 3, piston 4, pipe joint 5, pressing plate
