Abstract
The utility model provides a grinding wheel spindle structure of a grinding machine. The grinding wheel spindle structure enables errors caused by external transmission during rotation of a spindle to be low and rotation precision of the spindle to be high and guarantees high grinding precision. The grinding wheel spindle structure comprises a support, a spindle, a grinding wheel carrier and an eccentric shaft. The grinding wheel carrier is tightly connected to an output end of the spindle. The front end of the spindle is supported in an inner mounting cavity of the eccentric shaft through a bearing. The eccentric shaft penetrates through an inner mounting hole of the support. The grinding wheel spindle structure is characterized in that one end of a flexible universal joint is tightly connected to a tail input end of the spindle, the other end of the flexible universal joint penetrates through a support tailstock and is tightly connected to the center of an end cover plate, a relief pulley is tightly connected to the periphery of the end cover plate, the relief pulley is sleeved to the outer circular surface of the support tailstock through a bearing, and the support tailstock is tightly connected to the rear end of the support.
Description
Technical field
The utility model relates to the technical field of structures of grinding machine, is specially a kind of grinding wheel main shaft structure of grinding machine.
Background technology
The grinding wheel main shaft structure of existing grinding machine, it is by the direct drive shaft of belt pulley, and main shaft easily produces rotation error in rotary course, cause the precision of its rotation not high.
Summary of the invention
For the problems referred to above, the utility model provides a kind of grinding wheel main shaft structure of grinding machine, and it so that the running accuracy of main shaft is high, and then guarantees that grinding accuracy is high so that extraneous transmission is very little to the error that main shaft produces in rotary course.
A kind of grinding wheel main shaft structure of grinding machine, its technical scheme is such: it comprises support, main shaft, grinding carriage, eccentric shaft, described grinding carriage is fastenedly connected the output of described main shaft, the front end of described main shaft is installed in the cavity by the inside that bearing is supported on described eccentric shaft, described eccentric shaft runs through the inside installing hole of described support, it is characterized in that: the afterbody input of described main shaft is fastenedly connected an end of rubber universal joint, the other end of described rubber universal joint runs through the center that is fastenedly connected closing panel behind the support tailstock, the circumferential off-load belt pulley that is fastenedly connected of described closing panel, described off-load belt pulley is loaded on the cylindrical anchor ring of described support tailstock by bearing holder (housing, cover), and described support tailstock is fastenedly connected the rearward end of described support.
It is further characterized in that: the front end bearing of described main shaft is specially static pressure thrust bearing.
After adopting structure of the present utility model, motor is passed to the support tailstock by the pulling force that belt is sent to the off-load belt pulley, finally be passed on the support, under the transmission of rubber universal joint, the off-load belt pulley only transfers a torque to main shaft, it so that the running accuracy of main shaft is high, and then guarantees that grinding accuracy is high so that extraneous transmission is very little to the error that main shaft produces in rotary course.
Description of drawings
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises support 1, main shaft 2, grinding carriage 3, eccentric shaft 10, grinding carriage 3 is fastenedly connected the output of main shaft 2, the front end of main shaft 2 is installed in the cavity by the inside that bearing is supported on eccentric shaft 10, eccentric shaft 10 runs through the inside installing hole of support 1, the afterbody input of main shaft 2 is fastenedly connected an end of rubber universal joint 4, the other end of rubber universal joint 4 runs through the center that is fastenedly connected closing panel 6 behind the support tailstock 5, the closing panel 6 circumferential off-load belt pulleys 7 that are fastenedly connected, off-load belt pulley 7 is set in the cylindrical anchor ring of support tailstock 5 by bearing 8, and support tailstock 5 is fastenedly connected the rearward end of support 1.The front end bearing of main shaft 2 is specially static pressure thrust bearing 9, and static pressure thrust bearing 9 can strengthen the system rigidity of main shaft 2.
