Abstract
The utility model aims at providing a machine tool beam of a fixed beam numerical control gantry milling machine, which comprises the machine tool beam provided with a rectangular horizontal guide slot at the middle part of the front surface. The machine tool beam is characterized in that the front surface of the machine tool beam is an oblique ridge which is arranged obliquely to the horizontal plane, and the horizontal guide slot is concavely formed at the middle part of the oblique ridge. The machine tool beam is designed into the oblique ridge type beam structure, thereby realizing the widen guide slot under the situation of not changing the dimension of the machine tool beam, greatly increasing the stressed area of the machine tool beam, promoting the gravity center of a main axis head to be tightly leaned against the center of the beam to the maximum extent to achieve the best motion accuracy and the super-strong heavy cutting ability, leading the overall structure to highlight the unique high stability, and ensuring the accuracy stability of the machine tool, the durability and the overall rigidity; furthermore, the machine tool beam has simple structure, convenient manufacture and low cost.
Description
Technical field
The utility model relates to mechanical industry machine-tool parts, it specifically is the lathe crossbeam of fixed beam type digital control planer-type milling machine (CNC) agent structure, being the Y of lathe, the basis that the Z axle moves, is one of essential condition that guarantees machine tool accuracy stability, persistence and complete machine rigidity.
Background technology
With reference to Fig. 1, Fig. 2.The lathe crossbeam 1 of fixed beam type digital control planer-type milling machine (CNC) agent structure is and is packed in column 4 tops horizontally disposedly, the lathe crossbeam 1 positive middle part vertical with horizontal plane offers horizontal guide groove (seeing Fig. 2 for details), the mainshaft mechanism 2 that comprises main shaft 21 and head 22 is bearing on the lathe crossbeam 1 movably by slide 3, design has the horizontal guide rail that matches with the lathe beam guideway on the slide 3, horizontal guide rail, guide groove constitute guideway, and mainshaft mechanism 2 reliably moves horizontally along lathe crossbeam 1 by the guideway that matches.Because lathe Y, Z axle weight and mobile support are all positive stressed by lathe crossbeam 1, so existing lathe crossbeam can be thickeied crossbeam front foundry goods, muscles and bones is encrypted, in order to guarantee rigidity, but simultaneously lathe crossbeam weight is increased the weight of, cost promotes, and also can strengthen because of lathe crossbeam weight reason causes the deflection of lathe base, and the retentivity of precision is relatively poor.In addition, this structure also can cause the spacing A of main shaft 21 centers and column 4 to increase, and adds to be easy to generate vibrations man-hour, and surface roughness is very poor during the heavy load cutting, and unfavorable again and Precision Machining is not suitable for high accuracy processing simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of guarantee fixed beam type digital control planer-type milling machine precision stability, persistence and complete machine rigidity the lathe crossbeam.
The utility model adopts following technical scheme:
A kind of lathe crossbeam of fixed beam type digital control planer-type milling machine comprises that positive middle part offers the lathe crossbeam of rectangular horizontal guide groove, is characterized in that: the front of described lathe crossbeam is a hip back of the body that is in tilted layout with horizontal plane; Described horizontal guide groove is arranged with in the middle part of the hip back of the body.
Further, the angle between the above-mentioned lathe crossbeam hip back of the body and the horizontal plane is 60 °～70 °.Best, the angle between the lathe crossbeam hip back of the body and the horizontal plane is 65 °.
The beneficial effects of the utility model: the lathe beam design is a hip back of the body formula beam structure, under the situation that does not change lathe crossbeam size, realize widened guide groove, the lifting surface area of lathe crossbeam is significantly increased, and impel the main tapping center of gravity to be close proximity to the crossbeam center to greatest extent, to reach best kinematic accuracy and superpower heavy cut ability, overall structure highlights its unique high stability, guarantee machine tool accuracy stability, persistence and complete machine rigidity, and simple in structure, easy to make, with low cost.

Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the side view (comprising slide and mainshaft mechanism) of the lathe crossbeam of existing fixed beam type digital control planer-type milling machine.
Fig. 2 is the enlarged diagram of the lathe crossbeam among Fig. 1.
Fig. 3 is a cross sectional representation of the present utility model.
Fig. 4 is a user mode schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 3, Fig. 4.A kind of lathe crossbeam of fixed beam type digital control planer-type milling machine comprises the lathe crossbeam 1 that level is more than, and the front of horizontal gird 1 is a hip back of the body 11 that is in tilted layout with horizontal plane, and this hip is carried on the back 11 middle parts and is concaved with the rectangular horizontal guide groove 111 of cross section.Angle a between the hip back of the body 11 and the horizontal plane is 60 °～70 °.Best, the angle a between the lathe crossbeam hip back of the body 11 and the horizontal plane is chosen as 65 °.
With reference to Fig. 4.Lathe crossbeam 1 is horizontally fixed on column 4 tops.Mainshaft mechanism 2 comprises the head 22 of main shaft 21 and drive shaft rotation, mainshaft mechanism 2 passes through slide 3 sliding bearings on lathe crossbeam 1, the bearing-surface of slide 3 be one with lathe crossbeam hip carry on the back corresponding inclined-plane, the corresponding horizontal guide rail 31 that matches with horizontal guide groove that is provided with on the bearing-surface middle part of slide, horizontal guide groove 111, guide rail 31 constitute the rail plate pair that bootable mainshaft mechanism 2 moves horizontally along lathe crossbeam 1.
As can be seen from Figure 4, lathe crossbeam 1 plays the power of bearing X, Z direction in bed piece, and its rigidity, bending resistance degree all seem particularly important.This lathe crossbeam 1 adopts hip back of the body formula, under the situation that does not change lathe crossbeam 1 size, realize widened guide groove 111, the lifting surface area of lathe crossbeam 1 is significantly increased, and shortened the spacing A between main shaft 21 centers and the column 4, impel main shaft 21 spindle nose centers of gravity to be close proximity to lathe crossbeam 1 center to greatest extent, guarantee that lathe crossbeam 1 has enough bending rigidities and torsional rigidity, to reach best kinematic accuracy and superpower heavy cut ability, overall structure highlights its unique high stability, guarantees machine tool accuracy stability, persistence and complete machine rigidity.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
