Technical Field
The utility model belongs to the technical field of the cutter and specifically relates to a compound sword with various diameter drill way reverse processing chamfers and specifically relates to a compound sword in compound chamfer sword field is related to.
Background
And an orifice at the position of an oil pump mounting surface on the cylinder block needs to be chamfered. For the traditional WD415, WD615 and D12 cylinder blocks, the chamfering position of the hole is positioned at the outer side of the workpiece, the cutter body and the workpiece do not interfere in the machining process, and the hole chamfering can be directly carried out in the forward direction according to the traditional process. However, in the cylinder block of type 03, 04, 05, or 07 of the MC-series product, the hole at the position of the oil pump mounting surface on the cylinder block is located inside the workpiece, and the space is narrow, so that chamfering is difficult.
Disclosure of Invention
The to-be-solved of the utility model is the above-mentioned technical problem that prior art exists, aim at providing the compound sword of the various diameter drill way chamfers of reverse processing.
In order to solve the above problem, the utility model adopts the following technical scheme: a composite cutter for reversely processing chamfers of orifices with various diameters comprises a cutter body, a cutter bar and a hard alloy chamfer blade, and is characterized in that the cutter bar is arranged at the front end of the cutter body, and the cutter body is also provided with an adjusting screw for adjusting the longitudinal position of the cutter bar and a fastening screw for fixing the cutter bar; the hard alloy chamfering blade is fixed on the cutter bar, and the cutting edge faces to the rear end of the cutter body.
The composite knife of the utility model has the advantages that the end part of the knife body passes through the round hole of the workpiece; then the height of the cutter bar is increased through adjusting the screw, so that the height of the blade is positioned at a processing position, and the workpiece can be subjected to reverse chamfering.
The utility model discloses simple structure, the commonality is strong, makes the course of working more nimble, simple and convenient, reduces the tool changing number of times and has improved work efficiency, and greatly reduced the cutter cost.
According to the utility model discloses, carbide chamfer blade can decide its drill way chamfer angle according to technology specification requirement.
As an improvement of the utility model, the front end of the cutter body is provided with a longitudinal cutter bar accommodating hole, and the bottom of the hole is provided with a longitudinal screw hole which is communicated with the adjusting screw in a matched manner.
As a further improvement, the lateral side of the cutter bar accommodating hole of the cutter body is provided with a transverse screw hole which is matched with the fastening screw and communicated with the cutter bar accommodating hole.
As a further improvement of the utility model, the side of the cutter bar is also provided with a flat groove matched with the set screw.
