Description

The screw mandrel erecting device of boring machine
Technical field
The utility model relates to a kind of boring machine, is specifically related to a kind of screw mandrel erecting device of boring machine.
Background technology
Boring machine is a kind of lathe that the existing pre-manufactured hole of workpiece is carried out boring with boring cutter.Usually, boring cutter rotates to be main motion, and the movement of boring cutter or workpiece is feed motion.Boring machine is mainly used in the machining high-precision hole or one-time positioning is finished the fine finishining in a plurality of holes, can be engaged in addition the processing of other machined surfaces relevant with hole fine finishining.But the horizontal leading screw of existing boring machine is installed in machine tool guideway outside, and leading screw and nut seat are installed in a side of bed piece, and the easy like this lathe that causes is subjected to force unbalance, the machining accuracy of boring machine is impacted, and reduced service life; And existing mounting means is generally the method that inspection bastinade table is proofreaied and correct, and causes production efficiency and machining accuracy all lower.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of screw mandrel erecting device of stressed uniform boring machine.
Technical scheme: for solving the problems of the technologies described above, the screw mandrel erecting device of boring machine of the present utility model comprises lathe bed, workbench, guide rail and motor, and described guide rail is provided with big palette, nut seat is installed on the big palette, and nut seat is provided be used to the through hole that penetrates screw mandrel; Described motor comprises main shaft, and the end near main shaft on the described lathe bed is provided with the screw mandrel installing hole; Described main shaft, screw mandrel installing hole and through hole are positioned at sustained height and on same straight line.
Be provided with bearing in the described screw mandrel installing hole, described screw mandrel is installed in the screw mandrel installing hole by this bearing.
Beneficial effect: the screw mandrel erecting device of boring machine of the present utility model; be skillfully constructed, structure is unique; by screw mandrel being installed on the center line of guide rail; and main shaft, screw mandrel installing hole and through hole arranged sustained height and be located along the same line; can guarantee the lathe stress equalization; can enhance productivity and machining accuracy, increase the service life, greatly improve the competitiveness of product in market.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the screw mandrel erecting device of boring machine of the present utility model comprises lathe bed 4, workbench 3, guide rail and motor 5, and described guide rail is provided with big palette, and nut seat 1 is installed on the big palette, and nut seat 1 is provided be used to the through hole 6 that penetrates screw mandrel; Described motor 5 comprises main shaft 7, and the end near main shaft 7 on the described lathe bed 4 is provided with screw mandrel installing hole 2; Described main shaft 7, screw mandrel installing hole 2 and through hole 6 are positioned at sustained height and on same straight line.
In the present embodiment, be provided with bearing in the described screw mandrel installing hole 2, described screw mandrel is installed in the screw mandrel installing hole 2 by this bearing.
The utility model is in use, and its installation process is as follows: at first, join the faying face that produces guide rail and big palette; Then, join the faying face that produces big palette and nut seat 1; Afterwards, nut seat 1 is fixed on the big palette; At last, on boring machine once the property clamping finish.After machining, decompose and install, whole process is simple and convenient.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
