Description

[0002] On large-scale moving beam gantry boring and milling machines, the up and down movement of the crossbeam is generally driven by a ball screw. The feed mechanism is generally supported by the two ends of the screw. The special feature of the feed mechanism is that the screw in the feed mechanism is used in an upright state, and because the machine tool is too large, the positioning and installation of the feed mechanism can only be carried out in a horizontal state. When positioning and installing the feed mechanism in a horizontal state, the middle part of the screw will inevitably deform due to its own weight due to the excessive length of the screw, which seriously affects the positioning and installation accuracy of the screw, and further affects the positioning accuracy and repeat positioning accuracy of the machine tool in the later stage. When positioning the feed mechanism, it is necessary to use a screw support device to support the screw and compensate for the flexural deformation of the screw.

[0024] As a technical optimization solution of the present invention, by setting the turning handle 15 , the operator can use the principle of a labor-saving lever to easily rotate the first threaded rod and the guide wheel 9 .

[0025] refer to Figures 1 to 3 Both sides of the top of the V-shaped support block 8 are provided with docking grooves, the top of the V-shaped support block 8 is movably connected with a pressure plate 11, both sides of the bottom of the pressure plate 11 are fixedly connected with docking rods 12, the docking rods 12 are movably connected to the docking grooves, and both sides of the top of the pressure plate 11 are movably connected with first bolts 13, and the first bolts 13 are threadedly connected to the V-shaped support block 8.

[0027] refer to Figure 1 and Figure 3 Lifting plates 14 are fixedly connected to both sides of the pressing plate 11 .
