More pay attention to the raising of product technology level and the exploitation of kind.Heavy gantry machine tool main transfer beam, Ding Liang, gantry-travelling, work
Station movement, overhead cross beam movement etc., ram is one of critical component of numerical control gantry machine tool, and the cutter of machine tooling is directly pacified
It is contained in the taper hole of ram main shaft, so the rigidity of this structure directly affects the dynamic property of whole lathe and the processing essence of part
Degree, and machining accuracy is the leading indicator of lathe.
Conventional heavy-duty lathe is all equipped with high-power, high pulling torque, high rigidity, high reliability milling head ram, and ram is arranged on
Inside slide carriage, slide carriage and ram contact surface paste one layer of wear-resisting politef and mould thin-skinned band, and during machine tool motion, ram is from slide carriage
Extend downwardly from, because ram is cantilever beam structure, ram bending rigidity is poor, when the cutting of lathe high pulling torque, ram bears main shaft
The impact of end tool cutting force, ram vibration is larger, and ram extension branch produces contains the curved of position from end to slide carriage
Bent deformation, thus causing displacement error and the angular error of main axle cutter, and error adds with the increasing of ram overhang
Greatly；There is rare lubrication at regular time and quantity in whole guide-soft-band face simultaneously, and the lubrication face oil film thickness being formed is thicker than sliding guidance face
Thin uneven consistent, thus leading to ram to produce error in the movement direction, this error directly affects the positioning precision of lathe
And machining accuracy.
Content of the invention
The technical problem to be solved is the defect existing for prior art, provides a kind of ram flexural deformation
Little digital controlled planer machine full bag static pressure ram structure.
For solving this technical problem, the invention provides a kind of digital controlled planer machine full bag static pressure ram structure, including
Slide carriage and ram, ram is square ram, and described ram is provided with eight guide pass, installs hydrostatic slideway between slide carriage and guide pass
Plate, hydrostatic slideway plate leaves static pressure area, forms static pressure oil film in static pressure area；Described slide carriage is provided with front pressuring plate, before ram
Between side and front pressuring plate, between right flank and slide carriage, gap adjustment block is installed；Described slide carriage upper end install guide rail scraper plate and
Oil-resistant rubber strip, oil scraping plate, oil-resistant rubber strip and integral sealing ring are installed in lower end, and slide carriage lower end is provided with swab case.
Described ram installs oil guard along its length.
There is pressure detecting, pressure gauge reading shows the pressure value in static pressure area in real time in described static pressure area.
Beneficial effect：The present invention by ram leading flank and right flank be provided with clearance adjusting unit so that ram with
Between slide carriage coefficient of friction little it is possible to be adjusted to suitable oil film thickness, each side of ram arrange multiple stationary. platen, with ram
Contact surface is big, is suitable for high-power, high pulling torque cutting, and when effectively improving high pulling torque processing, the flexural deformation of ram is it is ensured that lathe
Precision, improves the machining accuracy of part, advantageously reduces ram temperature rise simultaneously.

Specific embodiment
Below in conjunction with the accompanying drawings and example specifically describes to the present invention.
Fig. 1 show the structural representation of the present invention.
The present invention includes slide carriage 1 and ram 4.
Described ram 4 is square ram, and described ram 4 is provided with eight guide pass 13, installs quiet between slide carriage 1 and guide pass 13
Pressure guide-rail plate 2, hydrostatic slideway plate 2 leaves static pressure area 11, forms static pressure oil film in static pressure area 11, and static pressure oil film is imitated by pumping
Should, play cushioning effect.
The guide pass 13 of described ram carries out integral grinding on slideway grinder, so that each guide pass is met parallel or vertical
Require.
There is pressure detecting, pressure gauge reading shows the pressure value in static pressure area in real time in described static pressure area 11.
Fig. 2 show the A of the present invention to schematic diagram.
Described slide carriage 1 is provided with front pressuring plate 5.
Between the leading flank of described ram 4 and front pressuring plate 5, between right flank and slide carriage 1, gap adjustment block 6 is installed, leads to
Cross adjustment gap adjustment block 6, the thickness of the static pressure oil film of fore-and-aft direction, left and right directions can be adjusted, make ram 4 each side static pressure
Oil film thickness uniformity in area 11, and make oil film rigidity reach maximum.
Static pressure oil is ceaselessly cycling in and out by internal circulating device, serves the effect reducing ram 4 temperature rise.
Fig. 3 show the I portion enlarged diagram of the present invention.
Described slide carriage 1 lower end is provided with swab case 12.
Guide rail scraper plate 7 and oil-resistant rubber strip 8 are installed in described slide carriage 1 upper end, and oil scraping plate 9, oil-resistant rubber strip 8 and are installed in lower end
Integral sealing ring 10, static pressure oil is sealed by oil-resistant rubber strip 8 and integral sealing ring 10.
When described ram 4 moves up and down, guide rail scraper plate 7 and oil scraping plate 9 scrape the static pressure oil on ram 4, so that static pressure oil is existed
Flow in the swab case 12 of slide carriage 1 lower end in the presence of gravity, static pressure oil return utilizes the swab case 12 of slide carriage 1 lower end to pass through copper pipe
Directly oil return is to system fuel tank.
Described ram 4 installs oil guard 3 along its length it is ensured that static pressure oil is on guide pass 13.
The operation principle of the present invention and specific：
1) by being provided with clearance adjusting unit so that friction is between ram and slide carriage in ram leading flank and right flank
Number is little to make oil film thickness uniformity in the static pressure area of ram each side it is possible to be adjusted to suitable oil film thickness, and makes oil
Film rigidity reaches maximum；
2) multiple stationary. platen are set in each side of ram, static pressure area area is big, big with ram contact surface, be suitable for high-power,
High pulling torque cuts, and when effectively improving high pulling torque processing, the flexural deformation of ram is it is ensured that machine tool accuracy；
3) dynamic rate of hydrostatic slideway with the increase of the frequency of oscillation on supporting surface and increase quickly.This
Planting vibration has pumping effect, alternately increases and reduce the output flow of hydrostatic slideway, and it may stop in moment or even change
Liquid flow path direction, because it wants consumed energy, this energy is subsequently transformed into the form of heat again and dissipates, therefore must block vibration,
Hydrostatic slideway can play cushioning effect, while improving the dynamic property of whole lathe, also will improve the machining accuracy of part.
The embodiment above of the present invention, is merely illustrative, and is not only, all within the scope of the present invention or equivalent this
Change in the range of invention is all surrounded by the present invention.
