Abstract
The invention discloses a ram mounting compensation device, and relates to the technical field of mechanical manufacturing. The ram mounting compensation device comprises a bearing compensation body; the bearing compensation body is in a square plate block shape; an annular oil duct is arranged in the middle of the bearing compensation body; an oil outlet is formed in the face, facing a ram, of the annular oil duct; the annular oil duct is connected with an oil pump through an oil pipe; an electromagnetic directional valve is arranged on the oil pipe. Compared with the prior art, the ram mounting compensation device is installed positioning the middle of a hole in the front of a spindle box; the oil outlet in the bearing compensation body faces the front end of the ram; the bearing compensation body is fixed to the spindle body through screws; after the front end face of the ram is provided with different accessories, the gravity center changes; the electromagnetic directional valve is powered on, the oil duct is communicated, and pressure oil is controlled by the electromagnetic directional valve to enter the bearing compensation body; the bearing compensation body generates upward action force; precision changes caused by weight changes when the ram is provided with the different accessories are compensated; the ram is prevented from downwards deforming, and therefore the machining precision of a machine tool is ensured.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of ram of numerical control floor type boring and milling machine installs compensation arrangement.
Background technology
Numerical control floor type boring and milling machine is the ideal equipment of heavy parts processing, ram is contained in the parts in the main spindle box upper aperture of boring and milling machine, appearance four sides is through the guide pass of Precision Machining as movement, the square hole of main spindle box is the moving guide rail of ram, traditional numerical control floor type boring and milling machine is after ram front end face installs different annex, the situation that ram is out of shape can be produced downwards, ram self center of gravity is changed, and cause main spindle box center of gravity to change, this phenomenon can affect precision and the rigidity of ram in process of production, thus reduction machine finish, the crudy of product is caused to can not get ensureing.
Summary of the invention
The object of this invention is to provide a kind of ram and install compensation arrangement, it can solve existing ram after front end face installs different annex, produce distortion downwards, affects the problem of machine finish and product processing quality.
In order to solve the problem, the technical solution used in the present invention is: comprise supporting compensating body, this supporting compensating body is that a square plate is block, ring shaped oil passage is provided with in the middle part of it, this ring shaped oil passage is provided with oil outlet towards the face of ram, described ring shaped oil passage is connected with oil pump by oil pipe, and described oil pipe is provided with solenoid directional control valve.
In technique scheme, technical scheme can also be more specifically: described supporting compensating body is connected with main spindle box by connector.
Further: described connector is screw.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to the present invention being contained in centre position, square hole place before main spindle box, when ram front end installation accessories, solenoid directional control valve is energized, oil circuit is connected, the present invention produces active force upwards, the distortion produced when ram front end face installs the annex of various Different Weight can be solved, the machining accuracy of lathe and product quality are improved.
2, the present invention makes ram keep good precision and rigidity, and has longer service life.
3, structure of the present invention is simple, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the sectional view that Figure 1A-A locates.
Fig. 3 is the scheme of installation of embodiment of the present invention supporting compensating body at main spindle box.
Fig. 4 is the sectional view at Fig. 3 B-B place.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of ram as depicted in figs. 1 and 2 installs compensation arrangement, comprise supporting compensating body 1, this supporting compensating body 1 is that a square plate is block, ring shaped oil passage 5 is provided with in the middle part of it, this ring shaped oil passage 5 is provided with oil outlet 6 towards the face of ram 3, ring shaped oil passage 5 is connected with oil pump by oil pipe, and oil pipe is provided with solenoid directional control valve.
A kind of ram as shown in Figure 3 and Figure 4 installs compensation arrangement, and supporting compensating body 1 is loaded centre position, square hole place before main spindle box 2, and the oil outlet 6 in supporting compensating body 1 is facing to the front end of ram 3, and supporting compensating body 1 is fixed on main spindle box 2 by screw 4.
After ram 3 front end face installs different annex, center of gravity changes, solenoid directional control valve is energized, oil circuit is connected, pressure oil is controlled to enter supporting compensating body 1 by solenoid directional control valve, and supporting compensating body 1 produces active force upwards, compensates the precision change that ram 3 causes because of weight change when installing different annex, prevent ram 3 from occurring the situation of distortion downwards, thus ensure the machining accuracy of lathe.
This ram installs the pressure that compensation arrangement compensates, the distortion produced when ram front end face installs the annex of various Different Weight can be solved, the machining accuracy of lathe and product quality are improved, and make ram keep good precision and rigidity, and there is longer service life, and structure is simple, easy to maintenance.
