Description
Technical field
The present invention relates to milling-boring machine technical field, more particularly, to a kind of applied to milling-boring machine ram installing accessory
Weight compensating mechanism.
Background technology
For the heavy duty machine tools of the class of milling-boring machine one, during operation, cutting workpiece, the part such as main spindle box, ram, main shaft
Because stress causes the change of lathe power system, caused the heat that machine tool component occurs by frictional heat, cutting heat and variation of ambient temperature etc.
Deformation, all can cause the relative position between machine tool component to change, destroy the accuracy of its relative motion, make the several of lathe
What precision, control accuracy and machining accuracy etc. changes, the overall performance of final reduction lathe.
Milling-boring machine main spindle box, ram deformation are analyzed as shown in figure 1, dotted line is the situation after deformation in figure, it may appear that
Because ram overhanging after because position of centre of gravity change caused by ram bow, ram overhang after caused by main spindle box bow the problem of.
The content of the invention
Add it is an object of the invention to the above mentioned problem for solving prior art appearance there is provided one kind applied to milling-boring machine ram
The weight compensating mechanism of dress annex, is solved by setting compensation oil pocket because being slided after ram overhangs caused by position of centre of gravity changes
The problem of main spindle box caused by after pillow is bowed, ram overhangs is bowed.
A kind of weight compensating mechanism applied to milling-boring machine ram installing accessory, it is characterised in that：Including a compensation oil
Chamber.The compensation oil pocket is below ram in main spindle box front end.The ram front end of milling-boring machine residing for this weight compensating mechanism has
Installing accessory, the compensation oil pocket provides single oil circuit and passes through oil pressure in a servo ratio pressure-reducing valve control compensation oil pocket
Size.
Compared with prior art, the present invention is by being to set compensation oil pocket to solve because of ram below ram in main spindle box front end
After overhanging because position of centre of gravity change caused by ram bow, ram overhang after caused by main spindle box bow the problem of, make lathe portion
Holding relative position between part is consistent, keeps the accuracy of relative motion, makes the geometric accuracy, control accuracy and processing of lathe
Precision etc. does not change, and improves the overall performance of lathe.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is milling-boring machine main spindle box, ram deformation figure；
Fig. 2 is overall structure diagram of the present invention；
In figure：1. main spindle box, 2. rams, 3. compensation oil pockets, 4. installing accessories, 31. servo ratio pressure-reducing valves.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
The structural representation of the present invention is as shown in Figure 2.A kind of weight compensating applied to the installing accessory 4 of milling-boring machine ram 2
Mechanism, it is characterised in that：Including a compensation oil pocket 3.The compensation oil pocket 3 is below ram 2 in the front end of main spindle box 1.This is heavy
There is installing accessory 4 front end of ram 2 of milling-boring machine residing for amount compensation mechanism, and the compensation oil pocket 3 provides single oil circuit and passed through
The size of oil pressure in one control compensation oil pocket 3 of servo ratio pressure-reducing valve 31.
Compensation principle of the present invention：After 2 front end installing accessory 4 of ram, with the continuous stretching of ram 2, the weight of annex
The additionally one torque shoulder blade that leans forward of increase of ram 2 can be made, the servo ratio pressure-reducing valve 31 at this moment controlled through digital control system is automatically controlled
The oil pressure of compensation oil pocket 3 gradually increases, and the thrust sun for making oil pocket upward to ram 2 also gradually increases, and generation one is opposite with pin
Torque pin, then change is compensated caused by the weight of attachment.Conversely, with the continuous retraction of ram 2, balancing force is also gradually
Reduce.
Although being described in conjunction with the accompanying embodiments of the present invention, patent owner can be in appended claims
Within the scope of make various deformations or amendments, as long as no more than the present invention claim described by protection domain, all should
Within protection scope of the present invention.
