A jig for preparing a chamfered structure of a blade

Abstract

The invention discloses a fixture for preparing a blade chamfering structure, which comprises a base, a driving device, a lever mechanism, a clamp body and a clamping plate; one end of the clamping body is fixed on the base, and the clamping plate and the driving device are respectively arranged at both ends of the top of the clamping body; The lever mechanism includes a connecting rod and a tapered cylinder and a plate respectively arranged at both ends of the connecting rod. The connecting rod is rotatably arranged inside the clamp body. The top of the clamp body is provided with a through hole corresponding to the tapered cylinder. In the hole, above the through hole is the opening of the splint, and the clamp body is provided with a gap at the joint with the driving device, and the driving device can drive the plate to move up and down. The jig used to prepare the blade chamfer structure of the present invention can make the tip of the blade and the center line of the base be on the same straight line, and the overall shape of the jig is circular, so as to ensure that the jig rotates around its own axis without affecting the tip of the blade, and does not limit the working of the machine tool. The degree of freedom can give full play to the advantages of five-axis machining.

Description

technical field [0001] The invention relates to the technical field of blade processing and preparation, in particular to a fixture for preparing a chamfered edge structure of a blade. Background technique [0002] In the field of hard cutting machining, a chamfer structure is usually prepared on the insert to improve the strength of the insert edge. In the prior art, the chamfer structure on the blade is usually prepared by a grinding machine, because the grinding machine can well ensure the quality of the edge of the blade without damaging the strength of the edge, and the grinding process has the best economical efficiency. [0003] Generally, the outer dimension of the blank blade is larger than that of the standard blade. Cylindrical grinding is required during processing to grind the outer dimension of the blade into a standard size, and then grind the chamfered part. Between the two, it is necessary to detect the outer dimension of the blade, and there are many proce...

Between the two, it is necessary to detect the outer dimension of the blade, and there are many processing procedures

However, the existing grinding machine itself does not have supporting fixtures for grinding chamfering structures, and users need to design corresponding fixtures according to processing requirements.
