The utility model discloses an off -load formula sliding guide that plano -boring and milling machine owner slip table is adjustable on guaranteeing the former hard inflexible basis of rail, through the increase to adjustable off -load slider, reduce hard rail contact stress, reducing friction power improves its and responds the precision to effectively prolong its life.
Description
[technical field]
The utility model relates to a kind of composition system of plane milling and boring machine, is specifically related to the adjustable discharging type rail plate of the main slide unit of a kind of plane milling and boring machine, belongs to machine tool technology field.
[background technology]
At present, the main slide unit guide rail form of the plane milling and boring machine that China is common is conventional three classes.One class is traditional fully hard rail structure, the good rigidly of this kind of slide unit structure, but rail friction power is large, and cause the staring torque of motor large, positioning precision is low, and low speed is easily creeped; It needs laminating usually, and to reduce frictional force, but laminating layer is easy to wear.Equations of The Second Kind is the rolling guide formula slide unit adopting linear slide rail; This kind of slide unit frictional force is little, and response accuracy is high, but its integral rigidity is poor, is not suitable for heavy duty or heavy cutting, and rolling guide impact resistance is poor, easily because accidental impact causes precision to be lost.The 3rd class is also had to be that static pressure type guide rail or rail plate add line slideway composition composite guide rails technology.
Therefore, for solving the problems of the technologies described above, necessaryly provide the main slide unit of a kind of plane milling and boring machine of innovation adjustable discharging type rail plate, to overcome described defect of the prior art.
[utility model content]
For solving the problem, the purpose of this utility model is to provide the main slide unit of a kind of plane milling and boring machine adjustable discharging type rail plate, it is on the basis ensureing former hard rail rigidity, several to adjustable off-load slide block by increasing, reduce hard rail contact stress, reduce frictional force, improve its response accuracy, and effectively extend its service life.
For achieving the above object, the technical scheme that the utility model is taked is: the main slide unit of a kind of plane milling and boring machine is adjustable discharging type rail plate, and it comprises slide unit base, slide unit stage body, ball slider and off-load hydraulic piston; Wherein, described slide unit base, slide unit stage body match; Some grooves are offered on described slide unit stage body; Described ball slider and off-load hydraulic piston are positioned in groove, and ball slider and slide unit base abut against, and off-load hydraulic piston and ball slider abut against.
The main slide unit of plane milling and boring machine of the present utility model is adjustable, and discharging type rail plate is set to further: in described slide unit stage body, be provided with fluid pressure line, described fluid pressure line is connected with off-load hydraulic piston.
The main slide unit of plane milling and boring machine of the present utility model is adjustable, and discharging type rail plate is also set to: the both sides of described slide unit base are provided with steel guideway; Described steel guideway contacts with ball slider.
Compared with prior art, the utility model has following beneficial effect:
1. the main slide unit of plane milling and boring machine of the present utility model adjustable discharging type rail plate carries out technology upgrading based on hard rail, and cost is low, effective, and applicable numerical control and common PLC control large and medium-sized varying load gantry mill, plane class lathe;
2. the main slide unit of plane milling and boring machine of the present utility model adjustable discharging type rail plate possesses general sliding-rolling composite guide rails technological merit, significantly can improve response speed, extends the guide precision life-span, improves positioning precision;
3. the adjustable discharging type rail plate of the main slide unit of plane milling and boring machine of the present utility model possesses dynamic load with conditioning function, and hydraulic pressure can carry out off-load adjustment when the load is varied, reduces the lower wearing and tearing of heavy duty and low speed jerking motion problem, reduces the surdimensionnement such as motor and coupling screw mandrel.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the adjustable discharging type rail plate of the main slide unit of plane milling and boring machine of the present utility model.
Fig. 2 is the enlarged drawing at I place in Fig. 1.
[detailed description of the invention]
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is the adjustable discharging type rail plate of the main slide unit of a kind of plane milling and boring machine, and it is made up of a few parts such as slide unit base 1, slide unit stage body 2, ball slider 3 and off-load hydraulic pistons 4.
Wherein, described slide unit base 1, slide unit stage body 2 match, and slide unit stage body 2 is positioned on slide unit base 1.On described slide unit stage body 2, offer some grooves 5, groove 5 is long parallel to face with guide rail length to face, ensures guiding accuracy.
Described ball slider 3 and off-load hydraulic piston 4 are positioned in groove 5, and ball slider 3 and slide unit base 1 abut against, and off-load hydraulic piston 4 and ball slider 3 abut against.
Further, in described slide unit stage body 2, be provided with fluid pressure line 6, described fluid pressure line 6 is connected with off-load hydraulic piston 4, and provides hydraulic oil for off-load hydraulic piston 4.
The both sides of described slide unit base 1 are provided with steel guideway 7, ensure that two guide rail vertical direction equivalent hydraulic faces are equal.Described steel guideway 7 contacts with ball slider 3.
The design principle of the main slide unit of plane milling and boring machine of the present utility model is adjustable discharging type rail plate is as follows: the power that guide rail bears mainly contains slide unit stage body 2, workpiece weight and cutting force composition, when the load is varied, adjustment off-load hydraulic piston 4 pressure, the then load of corresponding increase or the carrying of minimizing rolling slide block 3, thus reduce the load of steel guideway 7.Off-load hydraulic piston 4 pressure adjusting can adopt manually according to design recommendation intervention adjustment, or gets dry run current ratio adjustment mode.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
