A turning and milling combined machine tool and a high-low rail balance structure thereof

Abstract

This utility model provides a milling and turning composite machine tool and its high and low track balancing structure. The structure includes a base and a main slide. An upper fixed slide and a lower fixed slide are fixed above the base. The upper plane of the upper fixed slide is vertically higher than the upper plane of the lower fixed slide. The main slide is slidably connected to the upper and lower fixed slides. The upper surface of the main slide is horizontal, and the thickness of the main slide near the lower fixed slide is greater than the thickness of the main slide near the upper fixed slide. Through this technical solution, firstly, the upper surface of the main slide is designed as a horizontal plane, which provides an installation reference that conforms to a horizontal slide. Secondly, by making the thickness of the main slide near the lower fixed slide greater than the thickness of the main slide near the upper fixed slide, the overall center of gravity of the main slide shifts to the lower fixed slide side, resulting in higher stability during the sliding operation of the entire main slide.

Description

Technical Field

[0001] This utility model relates to machine tools, and in particular, to a turning-milling composite machine tool and its high and low track balancing structure. Background Technology

[0002] Currently, a slant bed design with a high-low rail structure exists in the machine tool field. Its specific technical solution has been disclosed in Chinese utility model patent announcement number CN217859944U. The structure described in this patent mainly consists of a bed body, a fixed table, and two sets of fixed slides. The fixed table is fixed to the bed body, and an upper fixed slide and a lower fixed slide are arranged in parallel on the table surface. The vertical height of the upper fixed slide is higher than that of the lower fixed slide. This high-low rail layout forms the basic structure of the slant bed. In the practical application of this type of high-low track machine tool, the same mounting table needs to be assembled on both the upper and lower fixed slide rails simultaneously, using the two sets of slide rails to achieve the left-right lateral movement of the mounting table. Because there is a preset vertical height difference between the upper and lower fixed slide rails, the table surface will naturally tilt after assembly, and the degree of tilt is directly determined by the height difference between the upper and lower fixed slide rails. This tilting structure has certain applicability when meeting the needs of specific machining scenarios. However, as these machine tools entered the market and were put into practical use, users raised new functional expansion requirements, namely, the need to add a horizontal slide to the mounting table to achieve more complex machining operations. However, the normal assembly, precise positioning, and stable operation of the horizontal slide all require the mounting table surface as a horizontal reference plane. The inclined table surface formed by the height difference between the high and low rails in the existing structure cannot provide a suitable mounting reference for the horizontal slide, making it difficult to guarantee its installation accuracy. This, in turn, affects the slide's motion accuracy and the overall machining performance of the machine tool. The existing high-low rail machine tool structure can no longer meet this new application requirement, therefore, it urgently needs to be redesigned and improved. Utility Model Content

[0003] In view of this, the first objective of this utility model is to provide a high-low track balancing structure that not only provides an installation reference that conforms to the horizontal slide, but also has high overall operational stability.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A high-low track balancing structure includes a base and a main slide. An upper fixed slide and a lower fixed slide are fixed above the base. The vertical height of the upper plane of the upper fixed slide is higher than that of the upper plane of the lower fixed slide. The main slide is slidably connected to the upper fixed slide and the lower fixed slide. The upper surface of the main slide is a horizontal plane, and the thickness of the main slide near the lower fixed slide is greater than that near the upper fixed slide.

[0005] Through the above technical solution, firstly, the upper surface of the main slide is designed to be horizontal, which can provide an installation reference that conforms to the horizontal slide; secondly, the thickness of the main slide near the lower fixed slide is greater than the thickness of the main slide near the upper fixed slide, thereby shifting the overall center of gravity of the main slide to the lower fixed slide side, resulting in higher sliding stability of the entire main slide.

[0006] Preferably, a counterweight is fixed below the main slide.

[0007] The above technical solution lowers the center of gravity of the main slide, further improving the sliding stability of the main slide.

[0008] Preferably, a secondary slide is horizontally slidably connected to the upper surface of the main slide, and a machine tool processing head is mounted on the secondary slide.

[0009] Through the above technical solution, the auxiliary slide can slide horizontally along the table surface of the main slide, thereby driving the machine tool processing head to slide horizontally, and ultimately adapting to the processing of more parts.

[0010] Preferably, the auxiliary slide is provided with a mounting base, the height of which gradually increases from the lower fixed slide to the upper fixed slide, and the machine tool processing head is mounted on the side of the mounting base near the upper fixed slide.

[0011] With the above technical solution, the center of gravity of a single mounting base is biased towards the side of the upper fixed slide, while the center of the main slide is biased towards the side of the lower fixed slide. After the mounting base is installed behind the main slide, the center of gravity of both will tend to be in the central position, thereby improving the operational stability of the entire mechanism.

[0012] Preferably, a reinforcing boss is provided between the mounting base and the secondary slide.

[0013] By employing the above technical solutions, strengthening the boss can improve the structural strength of the connection between the mounting base and the auxiliary slide.

[0014] Preferably, the machine tool processing head is vertically slidably connected to the vertical plane of the mounting base, and further includes a drive cylinder mounted on the mounting base, the drive cylinder being used to drive the machine tool processing head to perform vertical reciprocating sliding.

[0015] Through the above technical solution, the drive cylinder can drive the machine tool processing head to move up and down, thereby adapting to the processing needs of more parts.

[0016] The second objective of this invention is to provide a milling and turning machine tool that not only provides an installation reference that conforms to the horizontal slide, but also has high overall operational stability.

[0017] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A turning and milling composite machine tool includes the aforementioned high and low track balancing structure.

[0018] Through the above technical solution, firstly, the main slide of the composite machine tool adopts a horizontal surface design, which can provide an installation reference that conforms to the horizontal slide; secondly, the thickness of the main slide near the lower fixed slide is greater than the thickness of the main slide near the upper fixed slide, thereby shifting the overall center of gravity of the main slide to the lower fixed slide rail side, resulting in higher sliding stability of the entire main slide; finally, after installing the mounting base, the overall center of gravity is biased towards the center, and the operation is equally stable.
