Abstract
The invention provides a grinding wheel spindle structure of a grinding machine, which is capable of greatly reducing the error caused by external transmission to a spindle in the rotation process and improving the rotation precision of the spindle so as to guarantee that the grinding precision is high. The grinding wheel spindle structure comprises a bracket, the spindle, a grinding wheel frame and an eccentric shaft, wherein the grinding wheel frame is connected with the output end of the spindle in a fastening way; the front end of the spindle is supported in an inner mounting cavity in the eccentric shaft through a bearing; and the eccentric shaft penetrates through an inner mounting hole in the bracket. The grinding wheel spindle structure is characterized in that the input end of the tail part of the spindle is connected with one end of a flexible universal joint in the fastening way; the other end of the flexible universal joint penetrates through a bracket tail seat and is connected with the center of an end cover plate in a fastened way; the end cover plate is circumferentially connected with an unloading belt wheel in the fastening way; the unloading belt wheel is sleeved on the outer annular surface of the bracket tail seat through the bearing; and the bracket tail seat is connected with the rear end part of the bracket in a fastened way.
Description
Technical field
The present invention relates to the technical field of structures of grinding machine, be specially the grinding wheel spindle structure of grinding machine.
Background technology
The grinding wheel spindle structure of existing grinding machine, it is through the direct driving main shaft of belt pulley, and main shaft is prone to produce rotation error in rotary course, causes the precision of its rotation not high.
Summary of the invention
To the problems referred to above, the invention provides the grinding wheel spindle structure of grinding machine, it makes that extraneous transmission is very little to the error that main shaft produces in rotary course, make that the running accuracy of main shaft is high, and then guarantees that grinding accuracy is high.
The grinding wheel spindle structure of grinding machine; Its technical scheme is such: it comprises support, main shaft, grinding carriage, eccentric shaft; Said grinding carriage is fastenedly connected the output of said main shaft; The front end of said main shaft is installed in the cavity through the inside that bearing is supported on said eccentric shaft, and said eccentric shaft runs through the inside installing hole of said support, it is characterized in that: the afterbody input of said main shaft is fastenedly connected an end of rubber universal joint; The other end of said 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 said closing panel, said off-load belt pulley is loaded on the cylindrical anchor ring of said support tailstock through bearing holder (housing, cover), and said support tailstock is fastenedly connected the rearward end of said support.
It is further characterized in that: the preceding end bearing of said main shaft is specially static pressure thrust bearing.
After adopting structure of the present invention; Motor is passed to the support tailstock through the pulling force that belt is sent to the off-load belt pulley, finally is passed on the support, under the transmission of rubber universal joint; The off-load belt pulley only transfers a torque to main shaft; It makes that extraneous transmission is very little to the error that main shaft produces in rotary course, make that the running accuracy of main shaft is high, and then guarantees that grinding accuracy is high.
Description of drawings
Fig. 1 is a front view structural representation of the present invention.
The specific embodiment
See Fig. 1; It comprises support 1, main shaft 2, grinding carriage 3, eccentric shaft 10, and grinding carriage 3 is fastenedly connected the output of main shaft 2, and the front end of main shaft 2 is installed in the cavity through 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, and 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 through bearing 8, and support tailstock 5 is fastenedly connected the rearward end of support 1.The preceding 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.
