Description

TECHNICAL FIELD

[0001] The utility model relates to screw adjusting technical field, concretely relates to a ground screw quick adjusting device. BACKGROUND

[0002] In large gantry installation and debugging, the base or workbench is relatively wide, and the middle part needs to be adjusted horizontally by ground screws, and the middle part of the ground screw also needs to be fixed by a draw bolt. In actual use, the tightness of the two needs to be adjusted to achieve the horizontal adjustment of the machine tool. The X-axis stroke of a large machine tool is usually 8 meters, and the width is 4 meters. A large number of ground screws need to be installed, about 15. Moreover, the length of the ground screw is relatively long, about 13 cm. The middle part of the ground screw also has a draw bolt, and the length of the draw bolt exceeds the length of the ground screw by about 10 cm.

[0003] The existing screw adjusting tool on the market is mainly a wind cannon sleeve. The standard length is 8 cm, and the length is 16 cm. It can be seen that if the wind cannon sleeve is used, only the tightness of the relatively short ground bolt can be adjusted, the tightness of the ground nut cannot be adjusted, and only non-standard parts can be customized. The non-standard parts not only have a long cycle and high price, but also have relatively fixed sizes, which have great limitations. For ground nuts of different sizes, corresponding sizes need to be customized, which inevitably increases the customization cost. In addition, during use, the tool needs to be frequently replaced, which seriously affects the work efficiency. UTILITY MODEL CONTENT
