Description

Machine clamp planing tool for planing machine

Technical Field

The utility model relates to the technical field of machining equipment, in particular to a mechanically clamped planing tool for a planing machine.

Background

The planing tool is a processing tool which is necessary for planing by a planing machine, and the planing tool structure is generally divided into the following two types:

welding tool bit type: the cutter in the structural form mainly has the following problems in use by adopting a welding structural form (the cutter blade made of high-speed steel or hard alloy is welded on cutter bodies of various cutters): 1. welding tools do not easily guarantee the consistency of the heat treatment of the insert, thus affecting the reliability and stability of the cutting efficiency and life of the tool. 2. The cutter is abandoned after being sharpened for several times, the variety of the cutter is large, and the processing cost is increased. 3. The groove shape of the cutter is completely ground by hand, so that operators are required to have a certain technical level, and the machining quality of the angle and the groove shape of the cutter head which is manually sharpened cannot be ensured. 4. Improper welding or sharpening of the cutter is easy to cause cracks, and the strength and the service life of the cutter are affected.

High speed steel integral planing tool: the tool bit and the tool bar are formed by processing a whole piece of high-speed steel, and each dimension element of the tool bit is ground after heat treatment. There are disadvantages: 1. and the whole high-speed steel is processed, so that materials are wasted and the cost is increased. 2. The service life of the cutter tip is reduced once for every regrinding. The knife tip is toothed once, so that the whole knife body is scrapped. 3. Bit grinding has a certain level of skill on the part of the operator.

Therefore, the present application proposes a planer clamping planer tool capable of quickly replacing a tool bit, so as to solve the above-mentioned problem.
