Planar rotary worktable of headstock device

Abstract

The invention relates to a planar rotary worktable of a headstock device. The planar rotary worktable is characterized by comprising a longitudinal slide bedplate, a spindle head angle plate, a locking screw, a rotary positioning shaft assembly and a planar rotary driving mechanism; a spindle head is fixedly mounted on the spindle head angle plate, the spindle head angle plate is arranged on the longitudinal slide bedplate and is connected with the right end of the longitudinal slide bedplate by the rotary positioning shaft assembly, the planar rotary driving mechanism which can drive the spindle head angle plate to rotate around the rotary positioning shaft assembly is arranged at the left end of the spindle head angle plate and the left end of the longitudinal slide bedplate, a long arc-shaped through groove is formed in the spindle head mangle plate, and the locking screw can penetrate the long arc-shaped through groove from top to bottom and is connected onto the longitudinal slide bedplate after penetrating the long arc-shaped through groove. The planar rotary worktable has the advantages that the planar rotary worktable is smart and reasonable in structural design, the headstock device which is supported and mounted by the aid of the planar rotary worktable is wide in workpiece inner circle machinable angle range, and accordingly the machining precision and the machining efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a high-speed internal grinding machine, in particular to a plane rotating workbench for a headstock device used to support and install a headstock device, and belongs to the technical field of mechanical processing equipment. Background technique [0002] The internal grinding machine is mainly used for grinding the surface of the inner hole and the end surface of the cylindrical, conical or other shapes. Existing internal grinding machine mainly is made up of lathe bed, the headstock device that is arranged on lathe bed and grinding device. The head frame device is used for the head frame to install and hold the workpiece and drive the workpiece to rotate. The grinding device is equipped with a grinding wheel, which is used for grinding the workpiece. [0003] The degree of automation of internal grinding machines commonly used in some enterprises is not high, and the grinding size is usually controlled by workers' measuremen...

AI Technical Summary

Problems solved by technology

However, the existing grinding machines have the disadvantage that the inner circle angle of the workpiece cannot be adjusted or the adjustment range is very small. For the occasions where the inner circle angle of the workpiece is required to be processed, multiple clamping is required, and multiple clamping will affect the grinding. precision

Moreover, the existing internal grinding machine still has the problem that the processing speed is not high enough, which also has an adverse effect on the grinding efficiency and grinding accuracy.
