Problems solved by technology
[0002] Existing grinding wheel dressing devices generally have a set of independent main shaft and drive system, and the overall structure is relatively complicated
The installation position is generally on the back of the head and tail frame of the machine tool, on the workbench, above and behind the grinding wheel frame. These positions are inconsistent with the rotation center of the workpiece, which will inevitably increase some unfavorable factors caused by assembly errors, which will also affect the grinding wheel.

Embodiment Construction
[0012] The present invention will be further described below in conjunction with drawings and embodiments.
[0013] Such as figure 1 , As shown in 2, the grinding wheel dressing device coaxially driven with the headstock spindle of the present invention includes diamond roller 4, headstock spindle 5, servo motor 8, body shell 7, and bearing 6.
[0014] The diamond roller 4 is directly installed on the shoulder of the headstock main shaft 5, and is on the same axis as the headstock main shaft 5. The entire shaft system is installed in the body shell 7 through the bearing 6, and the servo motor 8 is installed at the tail end of the entire shaft system, and passed The corresponding speed regulating device drives the entire spindle system to rotate, and the front end of the headstock spindle 5 is equipped with a standard top 2 and a dial 3, so that the workpiece 1 can be driven to perform rotary motion.
[0015] Generally, when grinding the workpiece 1, only a relatively low rota...

The invention relates to a grinding wheel dressing device being coaxial with and sharing driving force with a headstock spindle. The grinding wheel dressing device comprises a diamond dressing roller, the headstock spindle, a servo motor, a body casing and a bearing, wherein the headstock spindle is installed in the body casing through the bearing. The grinding wheel dressing device is characterized in that the diamond dressing roller is directly installed on the headstock spindle. Due to the fact that the grinding wheel dressing device is coaxial with and shares driving force with the headstock spindle, a shafting structure and a driving system are simplified, the structure of the dressing device is greatly simplified, the overall machine-tool structure is more compact, and production cost is reduced. In addition, the dressing axis of the diamond dressing roller is coaxial with the rotating axis of a workpiece, the dressing error is reduced, and the grinding wheel dressing accuracy is improved.
Description
technical field [0001] The invention relates to a grinding wheel dressing device, in particular to a grinding wheel dressing device which is coaxially driven with the main shaft of a head frame. Background technique [0002] The existing grinding wheel dressing devices generally have a set of independent main shaft and driving system, and the overall structure is relatively complicated. The installation position is generally on the back of the head and tail frame of the machine tool, on the workbench, above and behind the grinding wheel frame. These positions are inconsistent with the rotation center of the workpiece, which will inevitably increase some unfavorable factors caused by assembly errors, which will also affect the grinding wheel. Modeling accuracy. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a grinding wheel dressing device coaxially driven with the main shaft of the headstock. Th...
