Abstract
The utility model discloses a ram mounting compensation device, and relates to the technical field of machine manufacturing. The ram mounting compensation device comprises a bearing compensation body which adopts a square plate shape, an annular oil duct is formed in the middle of the bearing compensation body, an oil outlet hole is formed in a surface, facing a ram, of the annular oil duct connected with an oil pump through an oil pipe, and a magnetic exchange valve is mounted on the oil pipe. Compared with the prior art, the ram mounting compensation device is mounted in the middle of the front hole of a spindle box, the oil outlet hole in the bearing compensation body faces the front end of the ram, and the bearing compensation body is fixed on the spindle box through bolts; when different accessories are mounted on the front end surface of the ram, the center of gravity changes, the magnetic exchange valve is powered on, the oil duct is connected, pressure oil is controlled by the magnetic exchange valve to enter the bearing compensation body, the bearing compensation body generates upward acting force so as to compensate precision change caused by weight change when the different accessories are mounted on the ram, the ram is prevented from downward deformation, and the machining precision of a machine tool is guaranteed.
Description
Technical field
The utility model relates to machinery manufacturing technology field, and especially a kind of ram of numerical control floor type boring and milling machine is installed compensation arrangement.
Background technology
Numerical control floor type boring and milling machine is the ideal equipment of heavy parts processing, ram is the parts that are contained in the main spindle box upper aperture of boring and milling machine, appearance four sides process Precision Machining is as mobile guide pass, the square hole of main spindle box is the moving guide rail of ram, traditional numerical control floor type boring and milling machine is installed after different annexes at ram front end face, can produce the ram situation of distortion downwards, ram self center of gravity is changed, and cause that main spindle box center of gravity changes, this phenomenon can affect precision and the rigidity of ram in process of production, thereby reduction machine finish, cause the crudy of product to can not get ensureing.
Utility model content
The purpose of this utility model is to provide a kind of ram compensation arrangement is installed, and it can solve existing ram and after front end face is installed different annexes, produce distortion downwards, affects the problem of machine finish and product processing quality.
In order to address the above problem, the technical solution adopted in the utility model is: comprise supporting compensation body, this supporting compensation body is a square plate bulk, its middle part is provided with ring shaped oil passage, 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, on described oil pipe, solenoid directional control valve is installed.
In technique scheme, technical scheme can also be more specifically: described supporting compensation body is connected with main spindle box by connector.
Further: described connector is screw.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, owing to the utility model being contained in to the centre position, front square hole place of main spindle box, when ram front end installation accessories, solenoid directional control valve energising, oil circuit is connected, the utility model produces active force upwards, can solve the distortion producing when ram front end face is installed the annex of various Different Weight, the machining accuracy of lathe and product quality are improved.
2, the utility model makes ram keep good precision and rigidity, and has longer service life.
3, the utility model is simple in structure, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cutaway view at Figure 1A-A place.
Fig. 3 is that the utility model embodiment supports the scheme of installation of compensation body at main spindle box.
Fig. 4 is the cutaway view at Fig. 3 B-B place.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
A kind of ram is as depicted in figs. 1 and 2 installed compensation arrangement, comprise supporting compensation body 1, this supporting compensation body 1 is a square plate bulk, its middle part is provided with ring shaped oil passage 5, 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 solenoid directional control valve is installed on oil pipe.
A kind of ram is as shown in Figure 3 and Figure 4 installed compensation arrangement, supporting compensation body 1 is packed into the centre position, front square hole place of main spindle box 2, and the oil outlet 6 on supporting compensation body 1 is facing to the front end of ram 3, and supporting compensation body 1 is fixed on main spindle box 2 by screw 4.
When ram 3 front end faces are installed after different annexes, center of gravity changes, solenoid directional control valve energising, oil circuit is connected, pressure oil enters supporting compensation body 1 by solenoid directional control valve control, and supporting compensation body 1 produces active force upwards, and the precision that compensation ram 3 weight change when different annex is installed causes changes, prevent that the situation of distortion downwards from appearring in ram 3, thereby guarantee the machining accuracy of lathe.
This ram is installed the pressure of compensation arrangement compensation, can solve the distortion producing when ram front end face is installed the annex of various Different Weight, machining accuracy and the product quality of lathe are improved, and make ram keep good precision and rigidity, and there is longer service life, and simple in structure, easy to maintenance.
