Abstract
The invention discloses a high-speed and strong grinding dynamic and static pressure grinding head of a heavy numerical control roller grinder, comprising a belt pulley, a main shaft, a first coupling device, a first connecting plate, a second connecting plate, a connecting sleeve and a second coupling device. The high-speed strong grinding dynamic and static pressure grinding head has the advantages of high rotating precision of the main shaft, good stability, strong rigidity, less vibration, high grinding precision and grinding ability since the moment is transferred to the main shaft flexibly by the first and the second coupling devices which transfer torque only, avoids transferring the radial moment generated by the belt pulley while transferring torque and overcomes the damage to the bearing by the strong belt pulling force.
Description
Technical field
The present invention relates to a kind of heavy-duty numerical control roll grinder high speed, high-rate grinding device, especially a kind of heavy-duty numerical control roll grinder high speed, high-rate grinding grinding dynamic and static pressure grinding wheel head.
Background technology
At present, the bistrique transmission of roll grinder all is to adopt belt pulley, directly be connected (by the swelling adapter sleeve) on the main shaft, the tensile force of belt acts directly on the main shaft like this, reduced the rigidity of main shaft, wearing and tearing to mainshaft rear bearing during startup are bigger, and during work, axis feeding (or retreating) makes belt pulley produce instantaneous tensioning or loosen has directly influenced spindle rotation accuracy.Thus, had a strong impact at grinding machine carry out at a high speed, the grinding accuracy during high-rate grinding.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of heavy-duty numerical control roll grinder high speed, high-rate grinding grinding dynamic and static pressure grinding wheel head, this bistrique makes grinding machine can obtain high grinding accuracy when carrying out high speed, high-rate grinding.
The present invention is in order to solve the technical scheme that its technical problem adopts: a kind of heavy-duty numerical control roll grinder at a high speed, the high-rate grinding grinding dynamic and static pressure grinding wheel head, comprise belt pulley and main shaft, be provided with first shaft coupling, first terminal pad, second terminal pad, the adapter sleeve and second shaft coupling, the belt pulley rotational positioning is in close main shaft power input one side of mill frame housing, first shaft coupling, second terminal pad, the adapter sleeve and the second shaft coupling activity are in mill frame housing near in the cavity of main shaft power input, first terminal pad fixedly connected to the inner side belt pulley outside end face, the affixed first terminal pad inboard of the outside power intake of first shaft coupling, affixed second terminal pad of the inboard clutch end of first shaft coupling outside, the inboard affixed adapter sleeve of second terminal pad outside power intake, affixed second shaft coupling of the inboard clutch end of adapter sleeve outside power intake, the affixed main shaft power input of the inboard clutch end of second shaft coupling.
Further technical scheme of the present invention:
Second shaft coupling is the swelling shaft coupling, and promptly second shaft coupling is that swelling is connected with main shaft.
The belt pulley rotational positioning in the structure of close main shaft power input one side of mill frame housing is: mill frame housing is fixed with the quill shaft bearing near main shaft power input one side, two rolling bearings that are set in distance are located in the bearing block, belt pulley is placed on the rolling bearing admittedly, and the cavity of quill shaft bearing constitutes the part cavity of mill frame housing near the main shaft power input.
Steel disc group two ends in first shaft coupling first and second terminal pad that is connected respectively.For easy to assembly, first shaft coupling is only used the steel disc group, the disc at its two ends need not, similar first and second terminal pad of the disc at two ends, just size does not match.
The invention has the beneficial effects as follows: when the transmission of driven by motor belt pulley, pass to adapter sleeve by first terminal pad, first shaft coupling and second terminal pad, pass to second shaft coupling by adapter sleeve again, thereby with transmission of torque to main shaft, drive grinding wheel chuck and emery wheel is driven by being loaded on tapered sleeve on the main shaft again, rotate with grinding wheel spindle.Because moment passes to main shaft by first and second shaft coupling flexibility, so purely can only transmitting torque, broken away from and in transmitting torque, also will transmit the radially moment that belt pulley produces originally, overcome the damage that big belt pull causes bearing, thereby make that the running accuracy of main shaft is higher, good stability, dynamic stiffiness is strong, is difficult for vibration.Therefore, the present invention has improved rotating accuracy, grinding accuracy and the grinding capacity (maximum grinding capacity reaches 130kg/h) of main shaft.
