Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

Referring to fig. 1 and 2, the device for testing the levelness of the cross beam of the planer type milling machine comprises two jacks 2 symmetrically arranged at the bottom of the cross beam 1, wherein a gasket 7 is arranged between each jack 2 and a guide rail A5, and each gasket 7 is a wood gasket.

The purpose of setting up the gasket is the guide rail A on the protection crossbeam, prevents that the jack from exerting oneself upwards, causes the injury to guide rail A.

The supporting device 3 is arranged between the two jacks 2 and aims to ensure that the level rises linearly, the level placing table 4 is arranged on the supporting device 3, the level placing table 4 rises and falls on the supporting device 3, the level placing table 4 is provided with a level, and the level is arranged between the two guide rails A5 of the beam 1. Place the spirit level and place the bench at the spirit level, this spirit level is prior art, and the figure is not shown, can guarantee spirit level rectilinear rise, can guarantee the levelness of spirit level again, because strutting arrangement sets up on the processing mesa, the levelness of processing mesa is in reasonable within range, therefore strutting arrangement also can guarantee the levelness.
