Grinding fixture of semicircular boring cutter and clamping process thereof

Abstract

The invention discloses a grinding fixture of a semicircular boring cutter and a clamping process thereof, and belongs to the technical field of grinding fixtures. The grinding fixture comprises a cutter bar and a clamping groove formed in the front end of the cutter bar. A chuck assembly is installed in the clamping groove, a fastening mechanism connected to the chuck assembly is connected with the cutter bar, and a workpiece is placed in the chuck assembly. A stabilizing mechanism for clamping the workpiece is mounted on the chuck assembly on the outer side of the workpiece. According to thegrinding fixture of the semicircular boring cutter and the clamping process thereof, elastic structures of arc-shaped edges of semicircular plates facilitate clamping and loosening of the workpiece.The height and size can be quite easily controlled through the simple and parallel upper and lower surfaces, a handle can drive a lead screw to rotate in the rotating process, the lead screw can drivesleeves on the two sides to get close to or get away from each other at the same time in the rotating process, clamping plates move oppositely to clamp the workpiece, a first side plate and a secondside plate enable gears to move on racks in the moving process, sliding rails provide guidance and limitation for a bracket and a shell, and the clamping firmness and stability are improved.

Description

technical field [0001] The invention relates to the technical field of grinding fixtures, in particular to a grinding fixture for a semicircular boring tool and a clamping process thereof. Background technique [0002] In the field of mechanical processing technology, the boring tool is one of the indispensable tools. In order to improve the scope of application of the boring tool and give full play to the cutting effect of the boring tool, there have been boring tools with different structures. The quality of the boring tool is mainly There are the following factors: 1. It can quickly remove chips and the chip groove is not easy to be broken down by iron chips; 2. The boring tool and its fixture can quickly dissipate heat to avoid the reduction of boring efficiency; 3. When the tool is worn, it can be timely Lubricate to reduce tool scrap rate. Boring tool is a kind of boring tool. The most commonly used occasions are hole processing, reaming, profiling, etc. Boring tool c...

AI Technical Summary

Problems solved by technology

Boring tool is a kind of boring tool. The most commonly used occasions are hole processing, reaming, profiling, etc. Boring tool can be used on boring machine, lathe or milling machine. At present, boring tool is used on boring machine It is installed in cooperation with the taper hole and taper surface at the front end of the boring machine spindle. This installation method makes the boring tool relatively loose with the connecting piece under the action of the axial cutting force during the cutting process. As for the phenomenon of tool dropping, the light ones cause cutting interruption, and the severe ones damage the tool or scrap the workpiece.
