Description

Technical Field

[0001] The present application belongs to the field of mechanical processing technology, and in particular relates to a tool and processing equipment. Background Art

[0002] At present, the conventional manufacturing method of T-type tools is to use a carbide rod to form it through overall grinding. However, the blade of a T-type tool is often larger in diameter and shorter in length, while the shank or neck has a small diameter but a longer length, resulting in a large amount of material to be removed from the shank or neck during the manufacturing process, resulting in long processing time, large material waste, and high manufacturing cost.

[0003] In order to reduce the manufacturing cost of the tool, a manufacturing process has been developed in which the tool head and tool rod are ground separately and then assembled end-to-end welded. Although this manufacturing method effectively reduces the amount of material removed and reduces manufacturing costs, the end-to-end welding connection method cannot guarantee the overall strength of the tool. The tool head is prone to falling off during use, affecting the production and processing of the product and even causing safety accidents. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a cutting tool to reduce the manufacturing cost and improve its overall strength.

[0005] The embodiment of the present application provides a tool, including a tool head and a tool handle. The tool head includes an end surface, the end surface is provided with a groove, and the tool handle includes a boss arranged at one end, the boss is arranged in the groove, and the boss and the groove are welded.

[0006] In the above-mentioned tool, the shank and the cutter head are processed separately, which reduces the amount of material removal and reduces the manufacturing cost of the tool. In addition, the boss of the shank is arranged in the groove of the cutter head and is connected by welding, which increases the contact area between the boss and the cutter head and forms a radial limit between the boss and the cutter head, which is beneficial to improve the connection strength between the shank and the cutter head, reduce the risk of separation between the shank and the cutter head, and improve the overall strength and safety of the tool.

[0007] In some embodiments of the present application, the tool head and the tool handle are supported by different materials, and the upper surface of the boss does not exceed the end surface of the tool head along the axial direction of the tool. When the tool rotates to process the product, the upper surface of the boss does not exceed the end surface of the tool head along the axial direction of the tool, which is conducive to reducing the risk of interference between the boss and improving the safety performance of the tool.

[0008] In some embodiments of the present application, the depth H1 of the groove and the thickness h1 of the boss satisfy the relationship of 0.05mm≤H-h1≤0.1mm. After the boss is arranged in the groove, the upper surface of the boss and the edge of the groove have a certain height difference, which is conducive to further reducing the risk of interference of the boss and improving the safety performance of the tool.

[0009] In some embodiments of the present application, the tool handle further includes a handle and a transition portion, wherein the transition portion connects the handle and the boss; the diameter d1 of the boss and the diameter d2 of the handle satisfy the relationship d2≥d1≥{2*F / (3π)}^1 / 2; wherein F is the design limit machining load of the tool. Designing the boss based on the relationship between the boss diameter and the design limit machining load of the tool is beneficial to improving the overall strength of the tool, improving the cutting strength of the tool, and thus improving the machining quality of the tool for the product.

[0010] In some embodiments of the present application, the tool handle further includes a shank, a transition portion and a neck, and the shank, the transition portion, the neck and the boss are connected in sequence; the diameter of the tool head is D and the diameter of the neck d3 satisfies the relationship d3 / D≤0.5.

[0011] In some embodiments of the present application, the thickness L of the tool head, the thickness h1 of the boss and the diameter d1 of the boss satisfy the relationship of 0.3*L≥h1≥0.08*d1, which is beneficial to ensure the boss and structural strength, improve the overall strength of the tool, and reduce the risk of tool damage.

[0012] In some embodiments of the present application, a position avoidance groove is further provided on the end surface of the cutter head, and the groove is located at the bottom of the position avoidance groove. By providing the position avoidance groove, it is convenient to process the cutter head and save the processing and manufacturing cost of the cutter head; moreover, the position avoidance groove can form an avoidance space, which is convenient for welding operation.

[0013] In some embodiments of the present application, the inner diameter D1 of the groove and the inner diameter D2 of the avoidance groove satisfy the relationship of 2mm≤D2-D1≤4mm, which facilitates welding of the boss and the cutter head, thereby helping to improve the connection strength between the boss and the cutter head.

[0014] In some embodiments of the present application, the welding connection is achieved by providing an adhesive member, which is located in the groove and bonds the cutter head and the boss.

[0015] An embodiment of the present application further provides a processing device, comprising the tool described in any of the aforementioned embodiments.
