New description: [New technical field] This creation is about the cutter head welding. It is easy to operate, stable and can avoid the structure of the tool, especially the welding fixture structure. The large-scale drilling and milling machine used by adults to get an electric shock or a change in the hand, as shown in the figure, is mainly based on a circular tube-shaped tool. The second tool structure is like the sixth number of cutter heads 3 (made of industrial diamonds) = 30—the circumference of the end is provided; it can be combined with the other part of the clamping body 3 of the processing machine 4, as shown by the other i), and the processing machine 4 is rotated by the clamping device (for example, the seventh body has a body 3 ◦ rotation] The cutter head 3 can be driven with the 〇 4 f; the plane or the hole is formed; the rotation is cut and the cutting is performed. The processing of the end circumference is performed by welding to the cutter body 3 (bonding strength, but conventional In the welding processing operation, it is better to hold the cutter head 3 so as to be adjacent to the cutter body 3 - the position of the clip 5 (such as the first person - shown), so as to facilitate the subsequent operation of the peripheral edge The following are missing: Shiyan processing, but the above 1. Because the hand is holding the cutter head 3, it is easy to shake, which causes the positioning accuracy to be poor. The situation is oblique. 2. "The author does not use the handheld operation. 3—Hand-held itching and injury, itching H (four), but if you are divided by two people Sub-5 and the connection of the injury, it is also labor-intensive, does not meet the economic benefits. M285405 3. In order to resist the high temperature during the welding operation, the general clip 5 is made of heat-resistant metal, so it is easy to conduct electricity and hurt when welding. In view of the above-mentioned shortcomings of the tool welding processing work, the creator has researched and improved the shortcomings of these shortcomings, and finally created this creation. [New content] This creation aims to provide a cutter head welding fixture structure. The main body is a two-piece clamping member that is oppositely engaged with a magnetic body. The clamping member has a side recess at least one side edge adjacent to the two end portions, so as to define a positioning portion at the two ends of the clamping member. And a side protrusion on the side of the side recessed portion is provided with an outwardly protruding side convex portion, and the magnetic force of the magnetic body enables the two clamping members to be attracted to the tool body wall surface by the side convex portion, and the side is The top surface of the convex portion cooperates with the side surface of the positioning portion to block the cutter head to be positioned at a predetermined position on the periphery of the cutter body, which is extremely simple in operation and stable in positioning for subsequent welding. This is the main purpose of the creation, which is based on the cutter head welding fixture structure of the tool. The welding head does not need to hold the cutter head with the hand grip, so it can effectively avoid burns or electric shock. To ensure the safety of work, this is another purpose of the creation. As for the detailed structure, application principle, function and effect of this creation, it can be fully understood by referring to the following description according to the drawings: [Embodiment] As shown in Figure 8, it is the structure of the tool joint M285405 and its processing and positioning method. The main components and their missing parts are as described above and will not be repeated here. The first picture is the construction of this creation. The exploded view, with reference to the combination diagram of the second figure, can be clearly seen that the present invention mainly includes two parts, a magnetic body 1 and a clamping member 2, wherein the magnetic body i is a magnetic material resistant to high temperature. The two sides are provided with a flat surface ii, and the clamping member 2 is formed in a long strip shape, and a portion having a length greater than _ 忒 magnetic body 1 is disposed adjacent to the two end portions. a hole 2 3, and a side recess 2 1 is respectively disposed at an edge of the clamping member 2 on the side of the two positioning holes 2 3 to define a positioning portion 24 of the clamping end of the element 2, and on the side The side of the recessed portion 2 1 is provided with an outwardly projecting side convex portion 2 2 such that an intermediate recess portion 25 is naturally formed between the two side convex portions 22, and the top surface of the two positioning portions 24 is formed. The upper end of each of the positioning portions 24 is provided with a flat stop surface 242. When assembled, the two clamping members 2 are attached to the magnetic body. The two flat faces of the body 1 • 1 1 and a positioning pin 2 3 1 can be pressed through the two positioning holes 2 3 of the clamping member 2, so that the two clamping members 2 can clamp the magnetic body 1 to form a Combined with fixation. The third to fifth figures are schematic diagrams of the phase-to-close positions of the cutter head and the cutter body during use of the present invention. As shown in the respective drawings, in use, the magnetic components of the magnetic body 1 can be used to enable the clamping members 2 on both sides. The side protrusions 2 2 are respectively attracted to the inner (or outer) side of the cutter body 30, and the side recesses 2 1 are kept flush with the top surface of the cutter body 30, and the cutter head 3 is attracted to the 24 The stop surface 2 4 2 ' can be used to position each of the cutter heads 3 to maintain the position of the tool body 30 at the periphery of the tool body 30 by the stop of the side protrusions 2 2; when the welding head, the cutter head 3 and the cutter body 30 When there is too much solder overflow, it can fall directly into the side recess 2 1 , and can effectively prevent the solder from scattering or sticking the side convex portion 2 2 and the cutter body 30 wall surface, and the two side convex portions 2 2 The intermediate recess portion 25 can effectively reduce the contact area between the clamping member 2 and the cutter body 30, and the end recess portion 24 of the positioning portion 24 can reduce the high temperature transmission of the cutter head 3, thereby reducing welding work. The high temperature is then transmitted to the clamping member 2 to enhance the ease of assembly and soldering operations. * In practical application, a chrome or nickel layer that is not easily soldered can be properly plated on the surface of the clamping member 2 to prevent excessive solder from causing adhesion between the clamping member 2 and the tool body 30. It can be seen from the above that the structure of the welding head of the tool of the present invention has the advantages of simple operation, stable positioning and avoiding human injury, and has industrial applicability, novelty and progress. However, the above description is only a preferred embodiment of the present invention, and φ is not intended to limit the scope of the present invention. That is, the equal changes and modifications made by the patent application scope of this creation are covered by the scope of the creation patent.
