Abstract
The utility model discloses a closed frame type horizontal double-faced numerical control boring miller which comprises a miller body and a workbench arranged on the miller body, wherein a left upright post and a right upright post are respectively fixed on the miller body, a left spindle box is arranged on the sliding guide rail of the left upright post, a right spindle box is arranged on the sliding guide rail of the right upright post, a cross beam is fixed between the upper end of the left upright post and the upper end of the right upright post, and hydraulic clamping devices are also respectively arranged on the moving pressing plates of the left and right spindle boxes. The closed frame type horizontal double-faced numerical control boring miller can prevent the spindle boxes from moving on the upright posts, and can prevent cutters on spindles from generating upright post rigidity and stability deviation when being used for cutting workpieces, thereby keeping the upright post rigidity, improving the upright post stability, improving the glossiness of machined parts, and ensuring the high coincidence of the precision of hole systems at two side surfaces of the machined parts.
Description
Technical field
The utility model relates to the numerical control machine tool technique field, especially a kind of sealing frame type horizontal type double-side digital-control boring-milling machine.
Background technology
The horizontal type double-side digital-control boring-milling machine is mainly used in processing content for to be distributed in large-scale, the super-huge long and narrow part on the two sides with the part center line; Workpiece is under the situation of a clamping; Can accomplish the Milling Process on boring, reaming, bore hole, dissected valley groove and plane; Realize No. one time clamping, multiple operation processing.But the horizontal type double-side digital-control boring-milling machine that uses at present; The main shaft casing on single upright column, move up and down with main shaft on cutter when workpiece is carried out cut; Column can produce rigidity and stable deviation, and can not highly overlap processed hole, processing parts two sides is precision.
The utility model content
The technical problem that the utility model will solve is: overcome the deficiency in the prior art, provide a kind of and keep Column stability and improve the column rigidity, prevent that column from producing the sealing frame type horizontal type double-side digital-control boring-milling machine of stable deviation.
The utility model solves the technical scheme that its technical problem adopted: a kind of sealing frame type horizontal type double-side digital-control boring-milling machine; Comprise lathe bed, be arranged on the workbench on the lathe bed; Be fixed with left column and right column on the lathe bed respectively, the rail plate of left column is provided with left main spindle box, and the rail plate of right column is provided with right main spindle box; Be fixed with crossbeam between left column upper end and the right column upper end, also be respectively equipped with the oil pressure clamping device on the moving press plate of left and right main spindle box.
The oil pressure clamping device is the unidirectional hydraulic jack that has spring.
The beneficial effect of the utility model is: the sealing frame type horizontal type double-side digital-control boring-milling machine that the utility model provides; Be fixedly connected with crossbeam in left and right column upper end; Prevent that main spindle box from moving on column and main shaft on cutter produce column rigidity and stable deviation when workpiece is cut; Kept the column rigidity and improved Column stability, improved the fineness of part to be processed, the hole that guarantees the part to be processed two sides is that the precision height overlaps.

The specific embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of sealing frame type horizontal type double-side digital-control boring-milling machine as depicted in figs. 1 and 2; Comprise lathe bed 1, be arranged on the workbench 2 on the lathe bed 1; The left column 3 and the right column 4 that are arranged on lathe bed 1 both sides and are fixedly connected with lathe bed 1, the rail plate of left column 3 is provided with left main spindle box 5, and the last rail plate of right column 4 is provided with right main spindle box 6; Be fixed with crossbeam 7 between left column 3 upper ends and right column 4 upper ends, make lathe form the hollow structure of a sealing.Left and right column 3,4 obtains extraordinary rigidity and precision stability; Avoid left and right main spindle box 5,6 on single upright column, move up and down with main shaft on cutter when workpiece is carried out cut; Left and right column 3,4 produces stable deviation, and the hole that guarantees the part to be processed two sides is that the precision height overlaps.
In order further to increase the rigidity and the cutting power of lathe, also be respectively equipped with oil pressure clamping device 8 on the moving press plate of left and right main spindle box 5,6.Oil pressure clamping device 8 is for having the unidirectional hydraulic jack of spring.When left and right main spindle box 5,6 stopped, oil pressure clamping device 8 worked, and with left column 3 and left main spindle box 5, right column 4 and 6 lockings of right main spindle box, made it to form a rigid unitary.This design makes lathe in working angles, slow down vibrations, has increased the rigidity and the cutting power of lathe, has improved the fineness of part to be processed.
Above-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
