Embodiment Construction

[0019] The so-called front end in this embodiment refers to the end close to the camshaft hole, and the so-called rear end refers to the side end away from the camshaft hole. See figure 2 , the present invention is used for the camshaft hole machining of diesel engine body, which comprises a tool rod 1 and a reamer 2, the reamer 2 is concentrically mounted on the cutter rod 1, and the front end of the reamer 2 is adjustable Boring cutter 3, the rear end of reaming cutter 2 is provided with reaming cutter head 21, and the circumferential surface of reaming cutter head 21 is uniformly welded with six cutting blades 22 (see Figure 4 ), which is responsible for large margin cutting, the leading angle of the boring tool 3 is 90°, the leading angle of the reaming tool 2 is 80°-85°, the front end face of the cutting blade 22 on the head of the reaming cutter is in contact with the boring tool 3 The distance L between the knife faces is greater than the width D of the camshaft hole...

Abstract

The invention provides a deviation rectification compound tool used for machining an axle hole of a cam of a diesel engine body. The deviation rectification compound tool can solve the problem that when an existing independent boring tool or a reaming tool directly conducts rough machining on a cam blank hole, the machining error is large, and therefore the subsequent semi-finishing and finishing precision of the axle hole of the cam of the engine body is ensured. The deviation rectification compound tool comprises a tool rod and a reaming tool. The reaming tool is concentrically arranged on the tool rod. The deviation rectification compound tool is characterized in that a boring tool is adjustably arranged at the front end of the reaming tool; a reaming tool bit is arranged at the rear end of the reaming tool; six cutting blades are evenly distributed on the circumferential face of the reaming tool bit; the tool cutting edge angle of the boring tool is 90 degrees; the tool cutting edge angle of the reaming tool ranges from 80 degrees to 85 degrees; and the distance between the front end faces of the cutting blades and the tool face of the boring tool is larger than the width of the to-be-machined axle hole of the cam.

Description

technical field [0001] The invention relates to the technical field of diesel engine processing tooling, in particular to the field of tooling for diesel engine body processing, in particular to a deviation-correcting compound cutter for machining camshaft holes of a diesel engine body. Background technique [0002] The body is one of the most important parts of a diesel engine, and its machining accuracy directly affects the reliability of the diesel engine, and the machining of the camshaft hole of the body is a difficult point in body processing. Usually, the camshaft hole of the body is firstly rough-machined by a special machine tool with a separate boring tool or reaming tool, and then the subsequent semi-finishing and finishing are performed; and due to the hole diameter and position tolerance of the blank hole The accuracy level of the cam is implemented according to the foundry industry standard, so the accuracy of the blank hole cannot meet the requirements of mach...
