Description

Technical Field

[0001] This application relates to the field of multi-axis machining equipment, and in particular to a bed structure and machining center. Background Technology

[0002] In the field of laser cutting, five-axis laser processing equipment is commonly used. This equipment employs a platform that coordinates the movement of the workpiece along three linear axes and two rotary axes. It uses a focused, high-power-density laser beam to melt the workpiece, achieving cutting and engraving. In conventional five-axis laser processing equipment, the drive components on the machine bed are usually assembled separately from the base. However, this connection method makes it easy for external vibrations or impacts to be transmitted to the drive components during operation, causing relative misalignment between the base and the drive assembly. This results in weak overall vibration resistance, making the equipment susceptible to interference from vibrations during processing, thus affecting the quality of laser cutting.

[0026] The following is combined Figures 1 to 5 The embodiments of this utility model are described below.

[0027] This application provides a bed structure, which includes a base 100, the base 100 being arranged horizontally;

[0028] A support 200 is disposed on the base 100, wherein the support 200 is disposed vertically on the base 100;

[0029] The guide rail assembly 300 includes a guide rail 310, which is integrally formed with the base 100 and extends along the length direction of the base 100.

[0030] During the processing, since the base 100 is fixed laterally, and the guide rail 310 is integrally formed with the base 100 and extends along the length of the base 100, the slider of the driving component can move stably along the guide rail 310. Compared with the guide rail that is detachably assembled to the base, this can more effectively suppress the interference of external environment or driving component vibration on the processing process.

[0031] Therefore, by integrally molding the guide rail 310 and the base 100, the assembly gap between the two is reduced, the rigidity of the bed structure is improved, and external vibrations or impacts can be isolated more effectively, reducing the impact of vibration on precision machining and creating conditions to ensure the surface quality of the machining work.

[0032] Optionally, the support 200 and the base 100 may be made of marble, which can improve the dimensional stability and deformation resistance of the bed and ensure long-term processing accuracy.

[0033] If the distribution of the traditional base 100 and legs 400 does not match the position of the support 200, the load of the support 200 will have an excessively long path transmitted through the base 100 to the legs 400. This can cause the middle of the base 100 to deform due to excessive bending moment, affecting the stability of moving parts. Therefore, in some embodiments, the bottom of the base 100 is provided with multiple legs 400 for height adjustment, and these legs 400 are spaced apart along the outer edge of the base 100. When installing the bed, the base 100 is leveled by adjusting the height of the multiple legs 400 spaced apart along the outer edge of the bottom of the base 100.

[0034] In related technical solutions, the base 100 is often set to be relatively long, while the support 200 is located near the middle of the base 100. The overall span of the intermediate structure is relatively long, resulting in poor stability at high speeds due to its own weight or vibrations from the driving components during equipment operation. Therefore, in some embodiments, the position of the support 200 corresponds to the installation positions of two oppositely arranged support legs 400. This correspondence between the support legs 400 and the support 200 allows the load of the support 200 to be directly borne by the lower support legs 400. In other words, the base 100 is shortened, and the support 200 directly bears the weight of the support legs 400. This reduces the span of the intermediate structure, avoids concentrating the load in the middle of the base 100, and reduces the risk of bending deformation of the base 100 or support 200 due to its own weight or external forces.

[0035] In actual configuration, a crossbeam is installed on the support 200, and a moving component is mounted on the crossbeam. When the moving component moves, the load is directly transferred to the support legs through the support. The shortened lever arm reduces the torque effect, further reducing vibration and swaying, and providing stability for the moving component under high-speed movement. Especially when the crossbeam on the base is under a large load, it can improve the stability of the equipment, thereby further improving the machining accuracy.

[0036] Furthermore, since it is not necessary to place the support 200 in the middle of the base 100, in some embodiments, the side of the support 200 away from the guide rail 310 is flush with the side edge of the base 100, so that the bed base 100 can be shortened as a whole, and there will be no concave or convex structure on the side of the bed, which facilitates the layout design of other components and thus improves the space utilization of the bed structure.

[0037] Furthermore, the outer edge of the support leg 400 is provided with a crash plate 410, and the crash plate 410 has through holes 411 for binding. During the transportation or use of the bed, the crash plate 410 covers the outer edge of the support leg 400. When subjected to external impact, the crash plate 410 directly bears the impact force, protecting the support leg 400 and the base 100 structure. When it is necessary to fix the bed, it can be bound and fixed with ropes or the like through the through holes 411 on the crash plate 410, enhancing the stability of the bed structure during transportation or use.

[0038] Furthermore, when the base 100 is long or bears a heavy load, relying solely on the outer edge support legs 400 for support would cause deformation in the middle of the base 100 due to excessive load. Therefore, a support leg 500 for load-bearing is provided between adjacent support legs 400. The support leg 500 increases the support points, distributes the load of the base 100 to more support locations, reduces the force on a single support point on the base 100, thereby enhancing the load-bearing capacity of the base 100, further reducing the deformation of the base 100 due to load, and improving the overall structural stability of the bed.

[0039] Traditional machine beds require an oil collection box on the base 100 to collect oil, which occupies space on the base 100 and may interfere with the movement of the drive unit. Therefore, in some embodiments, the base 100 is provided with an oil drain groove 110 extending outwards from the base 100. An oil drain hole 120 is located on the side of the base 100 near the guide rail 310, and the oil drain hole 120 communicates with the oil drain groove 110. In this way, residual oil on the base 100 flows into the oil drain groove through the oil drain hole 120, flows outwards along the path of the oil drain groove, and is finally discharged along a predetermined path, thus eliminating the need for an additional oil collection device and allowing for direct discharge. This reduces the space occupied by the base 100, saves machine base space, avoids interference with the movement of the drive unit, and facilitates further optimization and improvement of the overall layout of the equipment.

[0040] In some embodiments, a laser generating assembly 600 is further provided on the top of the support 200, and the laser generating assembly 600 is arranged along the width direction of the support 200. The laser generating assembly 600, located on the top of the support 200, can shorten the optical path compared to a laser originally located on one side of the support 200, thereby reducing intermediate optical components, reducing optical losses and assembly difficulty, and lowering the risk of misalignment of optical elements such as reflectors and beam expanders on the laser generating assembly 600 due to mechanical deformation or temperature changes. Simultaneously, the laser generating assembly 600 does not occupy the movement space of the drive assembly, making the overall machine tool bed more compact.

[0041] This application also provides a machining center including a bed structure as described in any of the preceding technical solutions. Since this machining center adopts the bed structure disclosed in the embodiments of this application, it possesses the technical advantages of the bed structure disclosed in the embodiments of this application. Furthermore, it can improve the machining accuracy, surface quality, operational stability, and layout compactness of the machining center, reduce maintenance difficulty and optical loss, and extend the service life of the equipment.
