Tool welding clamp jig and method

Abstract

The invention provides a tool welding clamp jig and method. The tool welding clamp jig is used for positioning a welding head and a tool bar, and comprises a clamp jig body, a bottom plate connected with one side of the clamp jig body, and a supporting table arranged on the clamp jig body, wherein the clamping jig body comprises a first mounting part connected to the bottom plate, a main body part arranged on the side, away from the bottom plate, of the first mounting part, and a second mounting part arranged on the side, away from the first mounting part, of the main body part; the first mounting part is provided with a positioning structure used for mounting the supporting table; the supporting table is used for fixing a welding head; a positioning hole for fixing the tool bar is formed in the second mounting part; and when the welding head is fixed to the supporting table, the tool bar fixed in the corresponding positioning hole is coaxial with the welding head. According to the tool welding clamp jig and method provided by the invention, the supporting table is mounted on the positioning structure, and the welding head and the tool bar are rapidly positioned and coaxial through the supporting table and the positioning hole, so that the welding centering precision, the welding yield and the welding efficiency are improved; and operation is simple, positioning can be rapidly achieved, and the labor intensity of workers is reduced.

Description

TECHNICAL FIELD [0001] The present invention belongs to the field of manufacturing high-precision tool, particularly to a method of welding and cutting tool clamp fixture. 【Background technique】 [0002] In superhard cutting tool (PCD, CBN, diamond or the like) the manufacturing process, is limited by the high cost of super-hard material, difficult to machine, and a thinner size and other factors, generally hard cutting tool machining using soldering; is welded precision super hard tool indispensable step in the manufacturing process, which directly affect the quality of post-processing tool and the tool productivity. [0003] Substantially related art welding process is divided into: the size of superhard material are required for processing and shank, the shank of superhard materials grinding and welding position, mainly in order to remove the oxide layer; applying solder paste, placement, remove the excess solder paste; then connected together by welding superhard materials an...
