A high-strength composite shock-absorbing tool holder

Abstract

The invention discloses a high-strength composite damping cutter bar, and is applied to a machine tool. The high-strength composite damping cutter bar comprises a cutter bar body, a guide ring is fixedly connected to the surface of the cutter bar body, threaded concave holes are formed in one side of the guide ring, a cutter bar supporting sleeve is detachably connected to one side of the cutter bar body, threaded holes are formed in the upper surface of the cutter bar supporting sleeve, a reinforcing rib is welded to one end of the cutter bar supporting sleeve, and a cutter head mounting groove is formed in one end of the cutter bar body. According to the high-strength composite damping cutter bar, the guide ring is fixedly connected to the surface of the cutter bar body, moreover, the guide ring is made of manganese steel, and the guide ring is attached to the inner wall of the cutter bar supporting sleeve, therefore, the phenomenon that a matching gap is too large due to abrasion can be effectively avoided, and the service lives of the cutter bar body and the cutter bar supporting sleeve are prolonged; and the reinforcing rib is attached to the outer wall of the cutter bar body,so that the strength, rigidity and torsion resistance of the cutter bar body are enhanced, and then deflection deformation of a product caused by the uneven stress caused by the torsion and the shearing force of the cutter bar body can be overcome so as to increase the strength of the bonding surface.

Description

technical field [0001] The invention belongs to the technical field of cutters, and in particular relates to a high-strength composite shock-absorbing cutter rod. Background technique [0002] The cutter bar is generally used together by connecting the cutter head. The boring tool is a kind of hole processing tool, usually with a round handle, and there are also larger workpieces using a square tool bar. holes, profiling, etc. But not only the inner hole can be processed, the outer circle of the end face can also be processed, but it is not used in this way. [0003] The existing tool rod is matched with the tool rod support sleeve. After a long time of use, the wear will be serious, and the matching gap will be large, which will cause the tool rod to run poorly. If the inner hole of the knife is defective, the support sleeve can no longer be used, and a new support sleeve needs to be remade, and when the length of the knife rod is adjusted, because there is no support, it...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a high-strength composite shock-absorbing knife rod, which is fixedly connected with a guide ring through the surface of the knife rod, and the guide ring is made of manganese steel, and the guide ring is attached to the inner wall of the knife rod support sleeve, which can Effectively avoid the phenomenon of too large matching clearance due to wear, prolong the service life of the tool holder and the tool holder support sleeve, and fit the outer wall of the tool holder through the reinforcing rib to enhance the strength, rigidity and torsion resistance of the tool holder, which can Overcoming the twisting and deformation of the product caused by the uneven stress caused by the torsion and shearing force of the cutter bar, so as to increase the strength of the joint surface, can effectively solve the problems in the background technology
