Description

Technical Field

[0001] This utility model relates to the field of tooling adjustment technology, and in particular to a bridge-type five-axis gantry machining center crossbeam anti-deformation assembly adjustment process device. Background Technology

[0002] Bridge-type five-axis gantry machining centers face more stringent precision requirements when processing composite materials such as carbon fiber. The linear motion precision of the horizontal axis beam is particularly critical, and the most significant factor affecting this precision is the sagging deformation of the beam under Z-axis load. Typically, achieving the required precision is achieved by increasing the beam's cross-sectional dimensions, which in turn leads to a substantial increase in the weight of the beam and other components. Therefore, exploring reasonable and simple reverse deformation adjustment methods without significantly increasing the overall weight is a worthwhile direction to investigate.

[0003] Currently, most five-axis gantry machining centers for processing composite materials exhibit significant sagging deformation of the crossbeam after assembly, making them unsuitable for shipment without adjustment. When this sagging deformation leads to out-of-tolerance accuracy of the crossbeam axis movement, the common solutions are to use shims on the guide rail positioning surfaces or, in severe cases, disassemble the machine tool and rework the crossbeam to adjust the guide rail surfaces. However, adjusting the crossbeam on-site when sagging deformation occurs is often risky, with unstable accuracy retention and a high risk of damaging the guide rail surfaces. When assembly adjustments fail to correct the sagging deformation, disassembling and reworking the crossbeam is time-consuming, labor-intensive, and costly. Therefore, a bridge-type five-axis gantry machining center crossbeam anti-deformation assembly and adjustment process device has been designed. Utility Model Content

[0015] First, let me explain the design intent of this utility model. Currently, most five-axis gantry machining centers for processing composite materials on the market exhibit significant sagging deformation of the crossbeam after assembly. Without adjustment, they cannot leave the factory. When the sagging deformation of the crossbeam causes the crossbeam axis motion accuracy to exceed the tolerance, most methods involve using shims on the guide rail positioning surface or, in severe cases, disassembling the machine tool to repair the crossbeam and milling the guide rail surface. When the crossbeam sagging deformation occurs, adjusting it on-site usually carries certain risks, and the accuracy retention is unstable, and it is easy to damage the guide rail surface, resulting in poor accuracy retention. When the sagging deformation of the crossbeam cannot be repaired through assembly adjustment, disassembling and repairing the crossbeam is time-consuming, labor-intensive, and wasteful of costs. Therefore, this utility model designs a bridge-type five-axis gantry machining center crossbeam anti-deformation assembly and adjustment process device.

[0016] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1-2As shown, a bridge-type five-axis gantry machining center crossbeam anti-deformation assembly and adjustment process device includes a crossbeam assembly 1. The crossbeam assembly 1 includes a crossbeam body 2. The crossbeam body 2 is provided with a horizontal fixing plate 3 and a side fixing plate 4. A crossbeam top seat 6 is provided on the top of the horizontal fixing plate 3 and the side fixing plate 4.

[0017] Several sets of anti-deformation assembly and adjustment components 5 are provided on the horizontal fixed plate frame 3 and the side fixed plate frame 4 of the crossbeam. The anti-deformation assembly and adjustment components 5 of the crossbeam are described in detail below. The anti-deformation assembly and adjustment components 5 of the crossbeam include a wire rope tightening end seat 7 and a wire rope fixing end seat 8.

[0018] A wire rope 9 is provided on the wire rope fixing end seat 8; one end of the wire rope 9 is connected to the wire rope fixing end seat 8 through a connecting pin 10, and a rope tension adjuster 11 is provided at the end of the wire rope 9 away from the wire rope fixing end seat 8; the rope tension adjuster 11 is connected to the wire rope tightening end seat 7 through a connecting pin 10.

[0019] The specific structure of this utility model has been described in detail above. The working principle of this utility model will be explained below: In use, multiple sets of anti-deformation assembly and adjustment components 5 are installed on the crossbeam assembly 1. The crossbeam of the composite material processing gantry five-axis machining center is in a horizontal state. The fixed connection positions of the crossbeam are on the left and right horizontal fixed surfaces of the horizontal fixed plate frame 3, while the remaining middle area is suspended. In this example, the total length of the crossbeam is 5500mm, and the load is not shown in the diagram. The total load weight is approximately 4 tons. The load slides on the horizontal guide rail of the crossbeam. When the load moves to the middle area, a relatively serious sagging deformation problem occurs, resulting in abnormal horizontal movement axis accuracy of the crossbeam load, measured at approximately 0.08mm, while the required accuracy is less than 0.02mm. Four sets of anti-deformation assembly and adjustment components 5 are provided, two sets symmetrically arranged on each side. The core component is a high-strength, heavy-load, low-extensibility rope tensioning adjuster 11, which has the advantage of being easy to install and adjust within the crossbeam. The head of the crossbeam... The fixed connection part of the adjustment device is the wire rope fixing end seat 8 and the wire rope 9 tightening end seat 7, which can be fixedly installed on the horizontal fixing plate 3 or the side fixing plate 4 of the crossbeam. The wire rope 9 is connected to the wire rope fixing end seat 8 through the connecting pin 10. The end of the wire rope 9 away from the wire rope fixing end seat 8 is equipped with a rope tension adjuster 11. The rope tension adjuster 11 is connected to the wire rope 9 tightening end seat 7 through the connecting pin 10. The rope tension adjuster 11 tightens the wire rope 9. The crossbeam component is an irregular part with a large length-to-diameter ratio. In use, the two ends are fixed and the middle is suspended without support auxiliary components. It is also far from the left and right fixed positions. Therefore, when the crossbeam moves horizontally under load, the crossbeam will have the maximum value of downward drooping deformation. Since the crossbeam is fixed on the left and right sides and the cross-sectional size is large, the crossbeam is subjected to uneven force. The introduction of this device has greatly changed this situation, maximizing the utilization rate of the overall rigidity index of the crossbeam and achieving complementary rigidity.

[0020] Assembly and usage method of the crossbeam anti-deformation adjustment device: During the pre-shipment accuracy calibration after the machine tool is assembled, abnormal data of the crossbeam load movement axis accuracy are measured and recorded using tools. This device, due to its flexible steel wire rope 9, is easy to install and can be installed and removed without restriction at any stage of assembly. Based on the measured sagging deformation data, external force (such as a jack) is applied upwards in the sagging area of ​​the lower part of the crossbeam to restore the crossbeam and load to their original deformation. Specific data is determined based on experience. Then, the rope tension adjusters 11 on the steel wire ropes 9 at both ends are adjusted to eliminate axial clearance, ensuring all four sets of the device are taut. The external force is then slowly released, and the accuracy is remeasured and compared. If the effect does not meet the expected value, the above operation can be repeated.

[0021] The anti-deformation assembly and adjustment process device for the crossbeam in this technical solution has an ingenious structural design, is highly usable, and is easy to install, reliable, and maintain. By using this anti-deformation assembly and adjustment process device, the sagging deformation of the crossbeam is effectively avoided, and the ease of installation is significantly improved.

[0022] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
