Grinding Tooling for Diesel Engine Oil Adjustment Fork Rod

Abstract

The invention discloses a grinding tooling of a fuel adjustment fork lever of a diesel engine. The grinding tooling comprises a base body, a locating shaft, a stop locating device and a feeler block, wherein locating pieces connected with a grinding machine workbench are arranged at the lower end of the base body; one end of the locating shaft axially stops and is located on a side wall of the base body; an inserting level hole of the fuel adjustment fork lever of the diesel engine can be just arranged on the outer side of the other end of the locating shaft in a sleeving manner; the stop locating device can stop and locate the fuel adjustment fork lever and the locating shaft; the feeler block can slide back and forth and be located on the base body in a length direction of a sliding groove in the fuel adjustment fork lever of the diesel engine; a no-go gauge is arranged at one axial end of the feeler block; a go gauge is arranged at the other axial end of the feeler block; the feeler block is just over against the sliding groove in the fuel adjustment fork lever of the diesel engine. During measurement, a workpiece is not required to be moved from a worktop; all machining and detection can be accomplished by one step mounting; the time for repeated mounting, dismounting and handling is saved; the machining efficiency and machining precision are greatly improved.

Description

technical field [0001] The invention relates to an auxiliary tooling for machining, in particular to a grinding tool for an oil adjusting fork rod of a diesel engine. Background technique [0002] There is an 8mm chute on the oil adjustment fork rod and the parallelism of the rod hole is 0.05mm. Because the shape of the fork rod is the sanded rough surface, it cannot be positioned and clamped. It is very difficult to grind the 8mm chute without special tooling. Originally, the V-shaped iron sandwich mandrel was used, and after being put on the fork rod, it was ground on a tool grinder and then ground. After grinding a knife, because the parallelism and symmetry could not be detected, the whole set of tooling had to be removed from the machine tool. Put the watch on the flat plate, check its symmetry repeatedly, and measure the data, and then put it on the tool grinder to watch and grind, forming a cycle processing mode from the grinder knife platform to the grinder. It tak...
