When the casting holes are deformed forwards, thepressure heads V 36 are used as a reference, and the pressure heads VI 41 apply pressure backwards for shape correcting; and when the casting holes are deformed backwards, the pressure heads VI 41 are used as a reference, thepressure heads V 36 apply pressure forwards for shape correcting, and thus servo pressure systems III are formed and used for completing shape correcting of the auxiliary frame in the front-back direction. - The working process of the auxiliary frame shape correcting device is as follows: firstly, the auxiliary frame is positioned and clamped, then shape correcting is conducted sequentially in the up-down direction, the left-right direction and the front-back direction, shape correcting of the automobile body mounting front points is completed first, and then based on the reference, the automobile body mounting back points are subjected to shape correcting.
- Compared with the prior art, the auxiliary frame shape correcting device of the disclosure has the following advantages that:
- The sliding tables I 20 are driven by the air cylinders I 18 to move horizontally, so that the pressure heads I 12 and the pressure heads III 25 are coaxial vertically, when casting holes are deformed upwards, the lower pressure heads I 12 are used as a reference, and the upper pressure heads III 25 apply pressure downwards for shape correcting; and when the casting holes are deformed downwards, the upper pressure heads III 25 serve as a reference, the lower pressure heads I 12 apply pressure upwards for shape correcting, and thus servo pressure systems I are formed and used for completing shape correcting of the auxiliary frame in the up-down direction.
- The sliding tables II 27 are driven by the air cylinders II 26 to move horizontally, so that the pressure heads IV 31 are located directly above the casting holes, then the air cylinders III 28 are started for driving the pressure heads IV31 to move downwards, the level of the pressure heads IV 31 is consistent with the level of the pressure heads II 17, when the casting holes are deformed leftwards, the pressure heads IV 31 are used as a reference, and the pressure heads II 17 apply pressure rightwards for shape correcting; and when the casting holes are deformed rightwards, the pressure heads II 17 serve as a reference, the pressure heads IV 31 apply pressure to inner walls of the holes for shape correcting, and thus servo pressure systems II are formed and used for completing shape correcting of the auxiliary frame in the left-right direction.
- When the casting holes are deformed forwards, the
pressure heads V 36 are used as a reference, and the pressure heads VI 41 apply pressure backwards for shape correcting; and when the casting holes are deformed backwards, the pressure heads VI 41 are used as a reference, thepressure heads V 36 apply pressure forwards for shape correcting, and thus servo pressure systems III are formed and used for completing shape correcting of the auxiliary frame in the front-back direction. - Through the device, the shape of the auxiliary frame can be spatially corrected up and down, left and right, and front and back. Two corresponding pressure heads can be used as references for each other, up-down deformation and front-back deformation can be eliminated, deformation caused by too large or too small hole spacing can also be eliminated, and thus the auxiliary frame shape correcting device is advanced in process, ingenious in conception, flexible, practical and convenient and fast to use.
- While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
