Description
Technical field
The present invention relates to milling-boring machine technical field, more particularly, to a kind of applied to milling-boring machine gravity of ram off-load
Compensation mechanism compensation 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, deformation master in figure
Will be from following aspects：
(1) because the parts such as ram itself and internal spindle Action of Gravity Field produce deflection deformation.
(2) ram is bowed caused by position of centre of gravity changes after ram overhangs.
(3) main spindle box caused by after ram overhangs is bowed.
(4) thermal stretching caused by ram, main shaft temperature distortion.
The content of the invention
It is an object of the invention to solve prior art appearance above mentioned problem there is provided one kind be applied to milling-boring machine ram weight
The compensation mechanism compensation mechanism of power off-load, by setting guide rail, roller, support bar, butterfly spring, bearing and adjusting screw can be with
Ram is operated steadily, improve feed accuracy.
A kind of compensation mechanism applied to milling-boring machine gravity of ram off-load, it is characterised in that：Including guide rail, roller, support
Bar, butterfly spring, bearing and adjusting screw；The roller can on the guide rail inside main spindle box scroll forward and backward, and by milling-boring machine
The off-load of ram weight on the guide rail of the main spindle box of milling-boring machine, off-load amount can be adjusted by adjusting screw；This is heavy
Power off-load compensation mechanism is arranged on below the ram center of gravity of milling-boring machine, can be manually adjusted, can be made the ram of milling-boring machine in full row
Load forces and its center of gravity are unloaded all the time on same vertical curve in journey, it is ensured that off-load is steady.
Compared with prior art, the present invention is by setting guide rail, roller, support bar, butterfly spring, bearing and adjusting screw
Ram can be made to operate steadily, improve feed accuracy.
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（A）It is the compensation schematic diagram of the present invention and milling-boring machine,（B）It is the overall structure diagram of the present invention；
In figure：1. guide rail, 2. rollers, 3. support bars, 4. butterfly springs；5. bearing, 6. adjusting screws；、Ram is represented to enter
The power born to guide rail；G represents gravity of ram；P is represented and is unloaded load forces.
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 compensation mechanism applied to milling-boring machine gravity of ram off-load, its
It is characterised by：Including guide rail 1, roller 2, support bar 3, butterfly spring 4, bearing 5 and adjusting screw 6；The roller 2 can be in main shaft
Scroll forward and backward on guide rail 1 inside case, and by the guide rail 1 of ram weight off-load to main spindle box, can be right by adjusting screw 6
Off-load amount is adjusted；This gravity off-load compensation mechanism is arranged on the lower section of ram center of gravity, can manually adjust, ram can be made to exist
Load forces and its center of gravity are unloaded all the time on same vertical curve in total travel, it is ensured that off-load is steady.
Compensation principle of the present invention：Bearing 5 is fixed on the underface of ram center of gravity, and ram weight compresses dish by bearing 5
Spring 4, is then pressed on main spindle box guiding rail 1 by support bar 3, roller 2 again, passes through the adjustment up and down of adjusting screw 6, Ke Yigai
Become the decrement of disk spring, and the spring force of disk spring further through roller by the guide rail of ram weight transmitting to main spindle box
On.So gravity off-load can be fallen P by ram by the device, and pressure that ram feeding guide rail is born () it is to be less than
The gravity G of ram, can make ram operate steadily, improve feed accuracy.
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.
