Description

TECHNICAL FIELD

[0001] The utility model relates to machine tool technical field, concretely is a lightweight stand of precision machine tool. BACKGROUND

[0002] In the modern mechanical processing field, the precision machine tool plays a vital role, and its machining precision directly affects the quality and performance of parts. As a key supporting component of the machine tool, the machine tool stand not only bears the load of various moving parts and cutting force, but also has an important influence on ensuring the structural stability and machining precision of the machine tool as a whole. With the continuous improvement of the performance requirements of machine tools and the pursuit of lightweight equipment in some specific application scenarios, the design of lightweight stands emerges as the times require. Under the premise of meeting the strength and rigidity requirements, the lightweight stand effectively reduces its own weight by using new materials (such as high-strength aluminum alloy, etc.) and optimizing the structural design (such as reasonable internal stiffener layout, hollow structure, etc.), which is convenient for the installation, transportation and use of the machine tool in some places with strict weight restrictions. However, there are some problems to be solved in the actual application of the lightweight stand.

[0003] On the one hand, in the hoisting process of the stand, the bottom of the stand is usually wider than the top and more prominent, which is easy to collide with surrounding objects. Even a slight collision may cause scratches, dents and other damage to the outer wall of the stand, thereby affecting the appearance and structural precision of the stand, and even changing the stress distribution of the stand, which may adversely affect the installation and adjustment of the subsequent machine tool and the precision maintenance during long-term use.

[0004] On the other hand, the stand is connected and fixed with other components (such as base, beam, etc.) in the machine tool through a plurality of fixing bolts. These fixing bolts are usually directly exposed to the external environment and are easily disturbed by external factors such as dust, cutting fluid splashing, water vapor, etc. during the daily use of the machine tool. Dust accumulation may accelerate the wear of the bolts, the chemical components in the cutting fluid may corrode the surface of the bolts, and water vapor may cause the bolts to rust. Once the bolts have the above conditions, the tightness of the connection will decrease, causing the connection between the stand and other components to loosen, eventually causing the machine tool to vibrate intensively, the machining precision to decrease, and other adverse consequences.

[0005] In summary, the existing protection means for the lightweight stand of the precision machine tool is relatively single, and there is a lack of a comprehensive protection measure that can effectively protect the whole stand during hoisting and avoid collision, and can seal and protect the connecting fixing bolts of the stand and isolate external interference during normal use. UTILITY MODEL CONTENTS

[0006] The purpose of this invention is to provide a lightweight column for a precision machine tool to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightweight column for a precision machine tool, comprising a column, a lifting ring installed at the top of the column, fixing grooves provided at both the left and right sides and the front and rear ends of the column, fixing bolts installed at the bottom of the inner cavity of the fixing grooves, and a base connected to both the left and right sides and the front and rear ends of the column by pins, a sealing plate installed on one side of the base, and one end of a spring installed on the other side of the base, with a protective plate installed on the other end of the spring.

[0008] Preferably, one side of the base is provided with an anti-slip ridge.

[0009] Preferably, a rubber pad is provided on the outer wall of the protective plate.

[0010] Preferably, the fixing groove and the sealing plate are matched and their positions correspond.

[0011] Preferably, the protective plate is arranged in an "L" shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The lightweight column of this precision machine tool can be installed in a suitable position by fixing bolts. The opening of the fixing groove can be sealed by the base and sealing plate, thereby preventing the fixing bolts from being directly exposed to the air. Through the cooperation between the spring and the protective plate, the column can be protected on all sides. The device has a simple structure and reasonable design. It can not only protect the column and effectively prevent the column from being damaged by collisions during hoisting, thus protecting the equipment and extending its service life, but also seal and protect the fixing bolts during normal use, preventing them from being affected by external factors and ensuring that the equipment can be used normally and stably, meeting the current market demand.
