Abstract

Provided is a split rail combination bed surface of a deep hole machining device. In the split rail combination bed surface, grooves are machined on the bed surface of a bed along the length direction, and a big-end-down trapezoid rail is machined into a plurality of short size trapezoid rails which are embedded in sequence in the grooves at two sides of the bed surface and the total length of which is the same with the bed surface. A small interval is arranged between a bottom surface of a main shaft box and the bed surface when the main shaft box of the deep hole machining device is located on the trapezoid rails at the two sides of the bed surface. The main shaft box operates only on the trapezoid rail surfaces at two sides of the bed surface, so that when a slight friction phenomenon happens between the bottom surface of the main shaft box and the bed surface, the rail of the friction part is proved to have recessed, and replacement is needed.

Description

Deep hole processing equipment split track combination bed surface

One, technical field

The utility model relates to a kind of application of deep hole processing equipment split track combination bed surface, belongs to mechanical manufacturing field.

Two, background technology

At present, known bed piece and guide rail are mostly one, the precision of guide rail has determined the precision of workpiece to be machined, when lathe uses certain hour, guide rail and the bed surface problem that simultaneously caves in will appear in position commonly used, make bed ways return to the original precision difficulty very large, especially for the lathe bed that the deep hole processing equipment of length more than 20 meters is arranged, the difficulty of its manufacture and maintenance is just larger.

Three, summary of the invention

For the lathe bed that is applicable to deep hole processing equipment, be convenient to manufacture and keep in repair simple and convenient needs, the utility model provides a kind of bed surface of split track combination.

The utility model solves the technical scheme that its technical problem adopts; Bed surface position at the lathe bed bilateral processes groove along its length, the profile of guide rail all adopts up-small and down-big trapezoidal, and this trapezoidal rails is processed into to the individuality of many short sizes, then this short size trapezoidal rails is arranged in order and is embedded in groove at the bilateral bed surface, reach and bed surface with long.When the main spindle box of deep hole processing equipment is seated on the bilateral trapezoidal rails, bottom surface and the bed surface of main spindle box leave slight clearance, and main spindle box just moves on bilateral trapezoidal rails face.

The beneficial effects of the utility model are; Adopt this trapezoidal rails, can make the two sides of main spindle box bottom surface trapezoidal groove and trapezoidal rails contact-making surface large, make bearing capacity large, good stability.In the process that main spindle box moves on bilateral trapezoidal rails face, when slight friction phenomenon appears in main spindle box bottom surface and bed surface, prove that depression has appearred in the guide rail at this position, should be changed, the lathe bed that adopts this kind of method to manufacture is easy to make, easy to maintenance, the lathe bed long service life.

Four, accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated;

Fig. 1. be that the utility model lathe bed master looks outside drawing.

Fig. 2. be that the utility model lathe bed is overlooked and looked outside drawing.

Fig. 3. be the side-looking part section installation diagram that the utility model lathe bed amplifies.

Fig. 4. be the utility model trapezoidal rails single-piece stereogram.

Between gusset.

Five, the specific embodiment

In Fig. 2, trapezoidal rails (2) is sequentially arranged in the groove of bilateral bed surface (3), and in the middle of lathe bed, gusset (6) plays the stable and rigidity effect that improves lathe bed (1).

In the embodiment shown in fig. 3, trapezoidal rails (2) is to be embedded in the groove that the bilateral bed surface (3) of lathe bed (1) processes in advance, and with alignment pin (4), trapezoidal rails (2) is positioned in groove, use connecting bolt (5) that trapezoidal rails (2) is fastened in groove, the effect of alignment pin (4) is to prevent trapezoidal rails (2) play in the groove of bed surface (3) again.

Claims

1. a deep hole processing equipment split track combination bed surface, is characterized in that: process along its length groove on the bilateral bed surface of lathe bed, then a plurality of up-small and down-big short size trapezoidal rails are arranged in order and are mounted in groove on the bilateral bed surface.
