Equipment for grinding surface of long shaft workpiece

Abstract

The invention discloses a device for grinding the surface of a long-shaft type workpiece, which comprises a guide rail arranged on a lathe bed, wherein the guide rail is provided with a grinding head sleeved on the workpiece annularly; the grinding head is equivalently provided with at least two grinding strips annularly; the grinding head is also provided with a structure to drive all the grinding strips to perform radial motions so as to enclasp or break away from the workpiece; and the grinding head is driven to perform axial reciprocating movement on the guide rail by a driving device, and achieves the processing of grinding the outer circular surface of the workpiece through the rotary motion of the workpiece and the axial reciprocating movement of the grinding head. The grinding head of the device is sleeved on the workpiece annularly and performs axial reciprocating movement along the guide rail simultaneously so as to ensure the straightness of the motion and the grinding precision of the workpiece surface in the grinding process, and solve the difficult problem that the processing quality cannot reach the design requirement in the process of the one-step grinding of the long-shaft kind workpiece, thus the workpiece roundness, the cylindricity and the surface roughness can achieve the designed specified value, and the product quality and the working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a grinding device suitable for surface grinding of long-axis workpieces. Background technique [0002] In the mechanical processing technology, the outer circular surface of the shaft workpiece is usually ground in the form of cylindrical grinding, and the outer circular surface of the workpiece is ground by grinding wheels, but if it is longer The workpiece, such as the cylinder piston rod with a length of more than 13 meters, is difficult to guarantee the machining accuracy of the workpiece by ordinary cylindrical grinding, especially in terms of roundness, cylindricity and surface roughness, which cannot meet the technical requirements According to the specified value, it can grind long-axis workpieces such as piston rods with a length of more than 13 meters at one time. There are no domestic literature records and reports. Contents of the invention [0003] T...
