Description

Technical Field

[0001] The utility model relates to the technical field of machine tool legs, in particular to a machine tool leg structure with good stability. Background Art

[0002] Machine tools refer to machines used to manufacture machines and machinery. They play a significant role in the modernization of the national economy. Machine tools primarily use turning tools to perform turning processing on rotating workpieces. Drills, reamers, reamers, taps, dies, and knurling tools can also be used on machine tools for corresponding processing. Machine tools are mainly used to process shafts, discs, sleeves, and other workpieces with rotating surfaces. They are the most widely used type of machinery in machinery manufacturing and repair factories. The bottom of the machine tools is equipped with a bed foot structure, which enables the machine tools to be placed flat on the ground during placement.

[0003] The patent document with the prior art publication number CN209078370U provides a machine tool foot structure with good stability, including a machine tool body, the horizontal shock-absorbing device includes a connecting ring, and the top side wall of the connecting ring is connected to the bottom side wall of the machine tool body, and a horizontal base is movably sleeved on the horizontal slide bar, the front and rear side walls of the horizontal base are both provided with horizontal springs, and the vertical base is movably sleeved on the vertical slide bar, the bottom side wall of the vertical base is provided with an adjustment device, and the bottom side wall of the adjustment device is provided with a support leg plug rod, the device plays a role of vertical shock absorption through the expansion and compression of the support leg spring, and plays a role of slowing down horizontal vibration through the expansion and contraction of the vertical spring and the transverse spring, thereby reducing the vibration generated when the machine tool is working, improving the stability of the device, avoiding accidental movement of the device, and ensuring the normal operation of the device.

[0004] However, during use, when the machine tool is placed in the installation position, the existing machine tool foot structure will appear uneven due to the placement position. In order to ensure that the machine tool can maintain good stability after being placed, the machine tool foot structure needs to be adjusted. However, during the adjustment process, due to the certain weight of the machine tool and the poor flexibility of the machine tool foot structure, it is not convenient for the staff to adjust the foot structure. For this reason, we propose a machine tool foot structure with good stability. Utility Model Content
