Problems solved by technology

This compensation and unloading method can effectively reduce the load carried by the guide rail and improve the straightness of the tool holder slide seat moving on the beam, but the unloading structure is complicated, and it is difficult to process the convex line on the upper surface of the unloading beam
[0007] Moreover, the above two unloading devices have not considered how to reduce the vibration of the machine tool

Embodiment 1

[0022] Such as figure 1 and figure 2 As shown, the machine tool is a large-span heavy-duty gantry CNC machine tool with a mobile gantry frame. The gantry frame includes a beam 1 and columns 6A and 6B fixedly connected to the two ends of the beam 1. The beam 1 is provided with guide rails. Small friction between the traversing slide 8 and the beam 1, the top guide rail 9 is set on the top of the beam 1, the side guide rail 10 is set on the side of the beam 1, and the traversing slide 8 is respectively provided with a top guide and a side guide The top guide part is slidably matched with the top guide rail, and the side guide part is slidably matched with the side guide rail 10.

[0023] The crossbeam 1 is a crossbeam with a hollow structure, and an unloading beam 2 of polymer concrete material is arranged in the hollow cavity of the crossbeam 1. The two ends of the unloading beam 2 are fixed in the hollow cavity at the end of the crossbeam 1. Adjusting screws 11 are respecti...

Embodiment 2

[0027] Such as image 3 As shown, Embodiment 2 is a large-span heavy-duty gantry CNC machine tool with a fixed gantry frame and a movable workbench. Its structure is basically the same as that of Embodiment 1. The difference is that the columns 6A and 6B are columns of hollow structure, and the columns The hollow cavities of 6A and 6B are respectively provided with supporting core columns 7A made of polymer concrete (the supporting core columns in column 6B are not shown), and the columns 6A, 6B and the supporting core columns are respectively fixed to the foundation. Since the supporting core column is provided, the two ends of the unloading beam 2 are respectively fixed on the top of a supporting core column, so that the vibration generated by the equipment can be absorbed more and faster.

Abstract

The invention discloses a large-span heavy gantry numerical control machine tool. An unloading beam made of polymer concrete materials is arranged in a hollow cavity of a beam of the large-span heavygantry numerical control machine tool. Supporting bases upwards penetrating through the beam are arranged at the two ends of the unloading beam correspondingly and provided with sliding wheels. A balance rope is wound around the sliding wheels, the first end of the balance rope is connected to the part, on the outer side, of the unloading beam, and the second end is connected to the part, on the inner side, of the unloading beam. According to the large-span heavy gantry numerical control machine tool, on one hand, the middle portion of the unloading beam can be upwards jacked by adjusting thetightness of the balance rope, the force is transmitted to the beam through an adjusting screw, the deflection of the beam can be effectively balanced, the moving linearity of a transverse moving sliding base on the beam is improved, and accordingly the machining precision of the machine tool is improved; and on the other hand, good strength of stand columns and the beam made of cast iron materials is sufficiently utilized, due to the character of excellent vibration damping performance of the unloading beam and a supporting core column made of the polymer concrete materials, vibration absorption is accelerated, the two parts are combined, and mutual complementation is achieved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a large-span heavy-duty gantry numerical control machine tool. Background technique [0002] Large-span heavy-duty gantry CNC machine tools generally refer to CNC machine tools with a weight of more than 30t and a gantry span of more than 5m. Gantry CNC machine tools are divided into two types: fixed gantry, mobile table and mobile gantry (also known as bridge type) according to whether the gantry moves. The bridge-type gantry machine tool is characterized by a small footprint and a large load-carrying capacity. The gantry travel can reach 20 meters, which is convenient for processing extra-long or extra-wide workpieces. [0003] For this type of machine tool, there are various factors that affect the machining accuracy of the workpiece. There are four types in summary: the first type is that the span of the gantry causes the beam to deflect; the second t...
