Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.Gantry machining center lathe bed bracing or strutting arrangement, is made up of spring support 1, spring 2, bearing pin 3, mounting seat 4 and rolling guide piece 5.
As shown in Figure 1, the structure of gantry machining center lathe bed bracing or strutting arrangement is: spring support 1 is rectangular cavities, be equipped with a circular open hole being positioned at upper surface 1/3 and 2/3 position, the degree of depth is 1/2 of spring support thickness, also be provided with through hole in circular open hole bottom dead center position and communicate with spring support 1 lower surface, spring support 1 corner location symmetry be provided with screwed hole.Mounting seat 4 is rectangular cavities, is equipped with a circle in the position of upper surface 1/4 and 3/4
Open pore, the degree of depth is 1/2 of mounting seat thickness, also establish and all have a circular open hole in the same position of lower surface, the degree of depth is 1/4 of mounting seat thickness, in the middle of the open pore of upper surface and lower surface, be provided with through hole and be connected, and the diameter of lower surface open pore is less than the diameter in upper surface open hole.Rolling guide piece 5 is rectangular cavities, is connected by screw with mounting seat 4.The annexation of spring support 1 and mounting seat 4 is: spring support 1 is connected by bearing pin 3 with the through hole in mounting seat 4, and bearing pin 3 is shaped as cylindrical stepped.Bearing pin 3 middle parts are provided with spring 2, and spring 2 is disk spring, adopt disk spring can bear the load that excursion is very large, and the deformation energy of its unit volume is larger, has good buffering vibration absorption ability.Between mounting seat 4 and spring support 1, gap is 1mm, can effectively prevent long-time
Contact causes contact surface abrasion, and gives the space with buffering in this device busy process.The present invention installs very convenient, without the plenty of time, and can ensure that workbench 6 table tops are indeformable, thereby improves the surface accuracy of processing work.
In order to realize better the function of this gantry machining center lathe bed bracing or strutting arrangement, if Fig. 2, Fig. 3 are respectively the syndeton schematic diagram of steel guideway on the present invention and machining center workbench and lathe bed and the location map of the present invention and machining center line slideway: two row line slideways 10 are arranged on both sides lathe bed 7 by screw, two row straight-line guide rail slide blocks are arranged on workbench 6 back sides, and lathe bed 7 has moved by the slide block on line slideway 10 with the relative motion of workbench 6.Be provided with in two row line slideway 10 centre positions the guide assembly that multiple devices are formed by connecting.On lathe bed, be paved with steel guideway 8, by screw, spring support 1 be fixed on to the back side of workbench 6, the lower surface of rolling guide piece 5 contacts with the upper surface that is arranged on the steel guideway 8 on lathe bed 7.
The use state of this gantry machining center lathe bed bracing or strutting arrangement: be that many devices combine when the actual use of this device.When workpiece clamping and when cutting on workbench, due to the gravity of workpiece and workbench self, can produce active force to pressing down, active force passes on spring support 1,
