Description

Technical Field

[0001] This utility model relates to the technical field of counterweight cylinder support base, specifically a support base for a counterweight cylinder of a vertical machine tool. Background Technology

[0002] The counterweight cylinder is a crucial safety component in machine tools such as vertical machine tools, gantry milling machines, and lathes that have heavy vertical motion components (such as spindle boxes and turrets).

[0003] Currently, the counterweight cylinder of a vertical machine tool is generally installed directly inside the machine tool column. The bottom of the counterweight cylinder is connected to a shaft pin via a connecting lug. This shaft pin is generally directly connected to two plates, which can be welded inside the vertical machine tool column. This method cannot further improve the stability of the vertical machine tool column. Furthermore, the stability and structural strength of the shaft pin are not good with this structure, which may lead to a decrease in the accuracy of the counterweight cylinder. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content
