Description
Technical Field
The utility model belongs to the technical field of the lathe technique and specifically relates to a novel crossbeam ram integrated configuration.
Background
The three-axis linkage gantry machining center is a multipurpose machine tool machining center for performing moving machining by X, Y, Z three axes, wherein most gantry machining centers adopt a workbench to move to solve the movement of an X axis, a Y axis and a Z axis do workmanship on a cross beam and a ram, the cross beam is fixed on an upright post, the ram can move left and right on the cross beam by virtue of a saddle, namely the saddle drives the ram to move on the cross beam to realize the movement of the Y axis, and the movement of the Z axis is solved by adopting the up-and-down movement of the ram relative to the saddle. Therefore, three-axis linkage is formed, and the gantry machining center can machine complex planes and curved surfaces. For the gantry-shaped structure, two sides of a beam are supported by two upright posts, and the right bottom of the beam is a workbench, so that a gantry-shaped structure is formed, and the gantry-shaped structure is called a gantry.
At present, in gantry machining centers on the market, most of the machining centers are provided with a slide saddle which is hung on a cross beam, and a ram is hung on the slide saddle, so that the slide saddle can move left and right relative to the cross beam and the ram can move up and down relative to the slide saddle. Since the saddle needs to move on the cross beam and the ram moves on the saddle, a wire gauge needs to be arranged on the cross beam and the saddle to fix the moving direction of the saddle and the ram. And the main shaft is arranged at the lowest end of the ram, and when the main shaft is processed, the main shaft should vertically exert force, and processing of different planes or different curved surfaces is solved by means of movement of X, Y, Z three shafts.
Because the beam, the saddle and the ram are nested one layer (namely, hanging type), and are hung on the beam, two cantilever structures in the horizontal direction and the vertical direction are formed. An important factor affecting the horizontal cantilever structure is the amount of extension of the ram, the longer the cantilever structure. Due to the existence of the cantilever structure, the gravity center line of the main shaft in the vertical direction is deviated, so that the gravity center line of the main shaft and the direction of the machining force required during machining are not on the same straight line, the deviation is generated, the machining precision during machining products is influenced, and meanwhile, the cross beam is enabled to bear extra bending moment during machining the products by the machine tool. Moreover, the cantilever structure can cause the force born by the upper wire gauge and the lower wire gauge to be different, so that the abrasion degree of the upper wire gauge and the lower wire gauge is different, and the necessity of the cantilever structure is more obvious in the later stage of production.
