Utility model content
The utility model is to provide a kind of four line rail ram gantry machining centers, and it is mainly to solve the existing lathe of prior art to only have two line rails, and when ram slides, rigidity is poor, thus the technical problem of main shaft to the poor grade of the machining accuracy of workpiece.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Four line rail ram gantry machining centers of the present utility model, comprise saddle, described saddle is provided with the ram that can slide up and down, and the saddle of ram both sides is provided with left and right line rail, and sliding occiput posterior saddle is provided with rear line rail, ram is connected with screw mandrel, screw mandrel is connected with servomotor, and ram is provided with main motor, and main motor connects main shaft by transmission device, main shaft top is provided with knife striking cylinder support, and knife striking cylinder support is provided with knife striking cylinder.Left and right line rail, rear line rail form four line rails, and when ram is slided in the above, rigidity improves, and has reduced the vibrations of main shaft, thereby has made the machining accuracy of main shaft higher.
As preferably, between described left and right line rail and saddle, be provided with left and right line rail slide block adjusting pad.Left and right line rail slide block adjusting pad can be adjusted the height of left and right line rail, thereby can be so that left and right line rail and ram are tightr ordinatedly.
As preferably, the side of described left and right line rail is provided with line rail pressure piece.Line rail pressure piece can be spacing on saddle by left and right line rail.
As preferably, described rear line rail is fixed on saddle by rear line rail lock-screw, can prevent that so rear line rail from swinging.
As preferably, described ram is provided with compensating cylinder, and it is more smooth and easy that compensating cylinder can guarantee that ram moves when moving up and down.
As preferably, described screw mandrel is provided with bearing, can make like this screw mandrel more smooth and easy rotationally.
As preferably, described transmission device includes the synchronous pulley being connected with main motor, and synchronous pulley is connected with main shaft by Timing Belt.Synchronous pulley, Timing Belt also can replace to as other transmission mechanisms such as gears.
Therefore, the utility model arranges left and right line rail, rear line rail on saddle, by four line rails, makes ram more stable slidably, thereby makes processing rigidity and the precision of main shaft higher, simple and reasonable for structure.
