A New Camshaft Profiling Lathe

Abstract

The invention discloses a novel camshaft copying lathe. The novel camshaft copying lathe comprises a rack, an explorator, a rocking arm lever, a hydraulic device, a lead screw, a follow-up structure and a cutter; the explorator makes contact with the bottom of the rocking arm lever; the middle portion of the rocking arm lever is hinged to the rack; the explorator drives the rocking arm lever to act when rotating; the upper portion of the rocking arm lever makes contact with the hydraulic device which drives the lead screw to horizontally move under the effect of the rocking arm lever; the lead screw is engaged with the follow-up structure and drives the follow-up structure to horizontally move; the cutter is arranged on the follow-up structure, and therefore special-shaped cutting can be performed on a rotating workpiece; and by means of unique design, the type of the follow-up structure is improved, and therefore it can be avoided that a rolling pin is stuck, and unsmooth movement of the cutter is prevented.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a novel camshaft profiling lathe. Background technique [0002] The camshaft profiling lathe mainly undertakes the rough turning, semi-finishing turning and finishing turning process of the peach-shaped camshaft. Due to the high processing efficiency of this type of equipment, it has always been the key equipment of the camshaft production line. However, when this type of equipment is processing the camshaft, there are often phenomena such as large error of the cam peach shape and knife beating. Every time a similar problem occurs, it is found that the sliding body of the knife holder is stuck, the needle roller row and the cage are deformed and twisted, and the needle rollers are worn into polygonal shapes. The same problem reappeared shortly after replacing the new needle roller and cage. Due to frequent failures, the surface of the sliding body and the tool holder seat h...

Problems solved by technology

[0007] When the cage is newly processed, in order to ensure the position between the φ2.5mm holes, multiple cages are fixed and drilled together, and the sliding body and the surface of the tool holder seat are ground at the same time, but the same problem occurs shortly after assembly. Because of the above-mentioned problems, this case should arise
