Abstract
The utility model discloses a round ram structure for a five-axis vertical machining center. The round ram structure comprises a ram and fixed rails installed on the ram. The ram is a round ram with a round cross section, the fixed rails are installed on the round ram, stretch in the length direction of the round ram, are distributed in a central symmetry mode with the axis of the round ram as the center and are in sliding fit with a sliding block fixed to a ram box, and the ram box is fixedly connected with a machine tool frame. Due to the adoption of a round ram structure and the layout of the four linear guide rails, the defect that unbalance loading torque and deformation can be generated easily due to the self-weight of the ram and the influence of cutting force during machining is overcome, the ram is high in rigidity and strong in anti-deformation performance, and machining precision stability is guaranteed; the round ram structure is suitable for the five-axis vertical machining center.
Description
Technical field
The utility model relates to machining center ram structure technical field.
Background technology
Ram is the critical piece of machining center, and its inside is provided with main shaft and main drive, and in the quality of ram self rigidity and processing, the size of distortion directly has influence on the machining accuracy of lathe.
At present with the machining center of the ram mostly side's of employing ram or trapezoidal ram structure, guide pass form two line slideways or the rail plates of adopting more, guide rails assembling is at the left and right sides or the rear side of ram, its shortcoming is due to ram deadweight and adds and affected by cutting force, easily produces unbalance loading moment and distortion.
Utility model content
The technical problem that the utility model solves is to provide a kind of five shaft vertical machining centers circles ram structures, makes it have higher self rigidity and non-deformability, keeps the stability of machine finish.
The technical solution adopted in the utility model is a kind of five shaft vertical machining center circle ram structures, comprise ram and be installed on the orbit determination on ram, ram is the rounded round and smooth pillow of cross section, on round and smooth pillow, orbit determination is installed, orbit determination is extended along round and smooth pillow length direction, and the distribution that is centrosymmetric of relatively round and smooth pillow axis, and orbit determination and slide block are slidably matched, slide block is fixed on ram case, and ram case is fixedly connected with lathe frame.
Described orbit determination is four, orbit determination by screw fastening in round and smooth pillow.
The beneficial effects of the utility model are, adopt the layout of circle ram structure and four line slideways, overcoming due to ram deadweight and adding affected by cutting force, easily produce the shortcoming of unbalance loading moment and distortion, ram rigidity is high, and non-deformability is strong, thereby keeps the stability of machining accuracy, and part processing is simple, easy to assembly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the upward view that Fig. 1 is corresponding.
Fig. 3 is slide block and ram relative motion relation figure.
In figure, be labeled as: the round and smooth pillow of 1-; 2-orbit determination; 3-screw; 4-slide block; 5-ram case, S1-circle ram stroke.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, five shaft vertical machining center circle ram structures of the present utility model, comprise round and smooth pillow 1, orbit determination 2, screw 3, slide block 4 and ram case 5.Orbit determination 2 is fixed on round and smooth pillow 1, has four, and relatively round and smooth pillow 1 is 90 ° of angles mutually to be installed, and screw 3 is for fixing orbit determination 2.Before and after each orbit determination is upper, two slide blocks 4 are installed, slide block 4 is fixed on ram case 5, has eight slide blocks.During work, slide block 4 maintains static with ram case 5, is fixed on lathe bedstead, and round and smooth pillow 1 vertically moves relative to slide block 4 with orbit determination 2.Due to the rigidity of round and smooth pillow 1 square ram and the trapezoidal ram higher than same specification, and the center of gravity of moving component is positioned at the center of four orbit determination 2, therefore this structure is except can significantly improving self rigidity of ram and the ability of opposing cutting deformation, also almost eliminated unbalance loading situation, greatly improved the machining accuracy of lathe, and because the distribution form of guide rail has been eliminated unbalance loading, can extend again the service life of moving component.
