Abstract

The utility model relates to a milling machine, which in particular to is a steering structure for the longitudinal feed of a milling working platform. The steering structure is designed for improving the accuracy of locating and the useful life of the longitudinal feed of the milling working platform. Four parallel dovetail-type or rectangle conduit ferrules and orbits adopted by the utility model are arranged at the corresponding positions of the bicycle saddle and the elevating seat of the working platform. In addition, the steering structure is adopted by the utility model for the clearance fit of the conduit ferrules and the orbits. With four steering structures adopted, the loss of significance for the steering of location can be avoided to the greatest extent.

Description

A kind of milling machine table length feed guiding structural

The utility model relates to a kind of milling machine, refers to the guiding structural of milling machine table length feed especially.

Usually, as shown in Figure 1 and Figure 2, the length travel of the workbench of milling machine in milling process is to realize longitudinal register by two dovetail grooves, 11 matched in clearance on the saddle 1 of two swallow-tail form protruding rails 21 on the elevating bracket 2 and workbench.Requirement height along with the milling machine machining accuracy, cause the required precision of displacement also high, so corresponding positioning accuracy also wants high, if but only by aforesaid two guide rails location guiding structural, require the machining accuracy of guide rail and guide groove and matched in clearance precision all very high on the one hand, will greatly improve the production and processing cost.Because in milling process, guide rail and guide groove all will be subjected to impulsive force on the other hand, easily make the distortion of guide rail guide groove, cause the loss of guide rail guide groove precision, influence the milling machine machining accuracy, shortening lathe service life.

At above defective, the utility model purpose is to provide a kind of loss that can avoid guidance accuracy, improves positioning accuracy, can improve the guiding structural of milling machine table length feed in the service life of lathe again.

In order to reach above purpose, the utility model by the following technical solutions: parallel respectively correspondence is provided with four guide grooves and guide rail, the mutual matched in clearance of guide groove and guide rail on the relevant position on the saddle of workbench and the elevating bracket.

The shape of described guide groove and guide rail can be swallow-tail form or rectangle.

Adopt above technical scheme, the length travel location of lathe is by four guiding structurals of mutual matched in clearance, the location structure of four guidings, this resetting structure can make the milling machine longitudinal register more accurate, overcome error, and, make the stressed corresponding less of each guide rail or guide groove by the impulsive force that four guide rails and guide groove bear lathe, deflection also so littler has been avoided the loss of significance of location guiding greatly.

The utility model will be further described below with reference to accompanying drawing.

Fig. 1 milling machine structural representation;

Fig. 2 is the milling machine length feed guiding structural schematic diagram of commonly using;

Fig. 3 is a milling machine length feed guiding structural schematic diagram of the present utility model.

Shown in Fig. 1,3, milling machine comprises the saddle 1 of workbench, elevating bracket 2, saddle 1 bottom surface of workbench offers four parallel vertical swallow-tail forms or rectangular recess 11, elevating bracket 2 upper surfaces also are provided with 4 corresponding swallow-tail forms or rectangle protruding rail 21, saddle 1 bottom surface of workbench contacts with elevating bracket 2 upper surfaces, swallow-tail form or rectangle protruding rail 21 matched in clearance on swallow-tail form on the saddle 1 of workbench or rectangular recess 11 and the elevating bracket 2, thus make the saddle 1 of the workbench of milling machine realize length feed according to swallow-tail form that cooperatively interacts or rectangle guide groove guide rail location.
