Spliced reamer

Abstract

The invention discloses a spliced reamer. The spliced reamer comprises a round hole, a cutter edge, a circular groove, a chamfer, a front cutter bar, a chuck, a hexagon nut, a first screw, a second screw, a third screw, a fourth screw, a fifth screw, a sixth screw, a handle, a rear cutter bar, a hilt, a first groove, a second groove, a first convex body and a second convex body, wherein the roundhole is formed in the center of the front end of the cutter edge, the circular groove is formed in the rear end of the cutter edge, the chamfer is arranged at the front end of the front cutter bar, the first groove and the second groove are formed in the tail end of the front cutter bar, the first convex body and the second convex body are arranged on the two sides of the interior of the chuck, the chuck is arranged inside the hexagon nut, the handle is arranged at the rear end of the hexagonal nut, the rear cutter bar is arranged at the rear end of the handle, and the hilt is arranged at thetail end of the rear cutter bar. According to the spliced reamer, the chuck and the front cutter bar are of a detachable structure, and therefore different cutter edges can be replaced according to machining requirements of workpieces, the time for replacing the reamer is saved, and the practical performance and the working efficiency of the reamer are improved.

Description

technical field [0001] The invention relates to a machining tool, in particular to a spliced ​​reamer. Background technique [0002] A reamer is a rotary tool used to remove the metal on the surface of a machined hole. The hole after reaming can obtain precise size and shape. The main function of the reamer is to improve the machining accuracy of the hole and reduce its The roughness of the surface is used for finishing and semi-finishing tools, and the machining allowance is generally small. At present, due to the rapid development of the degree of mechanization, the application rate of the reamer is very high for the machining accuracy of the hole in the application of machining. [0003] In actual processing, the existing reamer is generally composed of a cutter body and a working part. When machining a hole with a large cutting allowance, the usual solution is to replace other tools for rough machining, and then use a reamer for fine reaming. At the same time, if the w...

Problems solved by technology

At the same time, if the workpiece needs to be chamfered, the tool needs to be replaced, which greatly reduces the production efficiency. At the same time, the handle of the reamer is smooth, and when it is installed and fixed with the clamping equipment, the fixing effect is often not good, causing the drill to loosen. off, slippery phenomenon
