Abstract
The invention discloses a transverse beam moving type gantry milling and boring machine with an automatic compensation device. The transverse beam moving type gantry milling and boring machine with the automatic compensation device comprises a transverse beam and a transverse beam base, an automatic telescopic compensation device is arranged between the transverse beam and the transverse beam base, and the automatic telescopic compensation device comprises two sets of guide rail pairs parallel to a Y-axis. The transverse beam moving type gantry milling and boring machine with the automatic compensation device is reasonable in structure and capable of automatically compensating linear stretching of the transverse beam generated when temperature changes, and avoids the fact that the precision of a machine tool is influenced by change of external temperature.
Description
Technical field
The present invention relates to a kind of beam movable plano milling and boring machine.
Background technology
When lathe is worked at the natural environment temperature, summer in the winter temperature difference can reach more than 30 ℃, and machine tool beam material commonly used is cast iron, and the iron casting heat coefficient of expansion: in 0 ~ 100 ℃ of scope, every degree is 1.04 * 10
-6, by this, calculate, the collapsing length of machine tool beam under natural environment is directly proportional to the length of the temperature difference and workpiece, take planer-type milling machine between crossbeam effective length 5-12 rice, temperature difference as 30 ℃ be example, the linear extendible amount of cast iron crossbeam is between 1.56-3.12mm.If apparatus of the present invention are not installed, crossbeam is under the impact of temperature, and downwarp or arch likely occur machine tool beam, can affect the precision of lathe.The very high lathe for requirement on machining accuracy, generally all in constant temperature workshop work, and the industry machining large workpiece such as, mine standby, metallurgical for boats and ships, extra large frock, engineering machinery and workshop are huge, are all to work at the natural environment temperature.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, can auto-compensation the plano milling and boring machine of the beam movable with autocompensation installation of the linear extendible that produces when variations in temperature of crossbeam.
Technical solution of the present invention is:
A kind of plano milling and boring machine of the beam movable with autocompensation installation, comprise crossbeam, beam base, it is characterized in that: the automatic telescopic compensation arrangement is set between crossbeam and beam base; Described automatic telescopic compensation arrangement is that two groups of guide rails that are parallel to Y-axis are paid.
Described guide rail pay comprise the moving slider fixing with crossbeam, with the fixing guide rail of beam base, moving slider and guide rail are slidably matched.
Between described moving slider and guide rail, by the roller sliding-contact, and roller and guide rail contact angle are 45 °.
Each guide rail has been paid four rollers and has been contacted with guide rail, is separately positioned on the left and right sides of slide block, and in the left and right sides, every side has up and down the extended line of each two roller center lines of homonymy mutually vertical.
The present invention is rational in infrastructure, can auto-compensation the linear extendible that produces when variations in temperature of crossbeam, avoid ambient temperature to change and affect the precision of lathe.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation that guide rail is paid.
Fig. 3 is the enlarged drawing that guide rail is paid.
The specific embodiment
A kind of plano milling and boring machine of the beam movable with autocompensation installation, comprise crossbeam 1, beam base 2, and automatic telescopic compensation arrangement 3 is set between crossbeam and beam base; Described automatic telescopic compensation arrangement is that two groups of guide rails that are parallel to Y-axis are paid.
Described guide rail pay comprise the moving slider fixing with crossbeam 4, with the fixing guide rail 5 of beam base, moving slider and guide rail are slidably matched.
Between described moving slider and guide rail, by roller 6 sliding-contacts, and roller and guide rail contact angle be 45 °, can 4 directions bear load.
Each guide rail has been paid four rollers and has been contacted with guide rail, is separately positioned on the left and right sides of slide block, and in the left and right sides, every side has each up and down; The extended line of two roller center lines of homonymy is mutually vertical.
