Description

Technical Field

[0001] The utility model relates to the field of mechanical processing parts, in particular to a heat shrinkable tool handle and a combined tool. Background Art

[0002] A heat shrink tool holder is a tool clamping device widely used in the field of mechanical processing. It uses the principle of thermal expansion and contraction to clamp the tool. The tool holder is heated to a certain temperature by a heating device. At this time, the inner diameter of the tool holder will expand and become larger. Then, the tool is inserted into the inner hole of the tool holder. After the tool holder cools down, its inner diameter will shrink and tightly wrap the tool, thereby realizing the connection between the tool holder and the tool. When disassembling the tool holder and the tool, it is also first heated to expand the inner diameter of the tool holder to release the fixation of the tool, and then the tool can be taken out of the tool holder.

[0003] In the prior art, when a tool processes a workpiece, a certain amount of heat is inevitably generated due to the cutting action and friction and other factors. During this process, the heat will gradually be transferred to the tool holder and the tool, causing the temperature of the tool holder and the tool to increase significantly. During the intermittent stage of processing, the tool stops cutting, the heat generation stops, and the temperature drops again. This repeated temperature change may cause the material of the heat shrink tool holder to undergo slight deformation, thereby affecting the tightness of the connection. In the subsequent processing process, this problem of decreased connection tightness may cause the tool to shake, deviate, etc., which may affect the processing accuracy of the workpiece. Therefore, a heat shrink tool holder and a combination tool are needed. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and to provide a heat shrinkable tool handle and a combination tool. Through the arrangement of structures such as the first connecting member and the second connecting member, after the connection between the handle body and the tool is completed, the first connecting member and the second connecting member are connected to the tool connecting member and the limit block, and then the first connecting member and the second connecting member are fixed using bolts and nuts. When the first connecting member and the second connecting member are fixed, the handle body and the tool can be fixed, thereby avoiding shaking, offsetting, etc. of the tool after a period of use, thereby avoiding affecting the subsequent processing accuracy of the workpiece. Through the arrangement of structures such as the bolt and the nut, when the tool needs to be disassembled, the nut can be unscrewed from the bolt to release the fixation between the first connecting member and the second connecting member, so that the first connecting member and the second connecting member can be separated to release the fixation between the handle body and the tool, and then the subsequent disassembly between the handle body and the tool can be carried out, which is simple and quick.

[0005] The utility model also provides the above-mentioned heat shrinkable tool handle and combination tool, including a handle body, the lower surface of the handle body is fixedly connected to a tool connecting piece, the inner surface of the tool connecting piece is provided with a tool, the outer surface of the tool is fixedly connected to a limiting block, the tool connecting piece is provided with a first positioning groove, the limiting block is provided with a second positioning groove, the inner surfaces of the first positioning groove and the second positioning groove are movably connected to two positioning blocks, wherein two of the positioning blocks are fixedly connected to the same first connecting piece, and the other two positioning blocks are fixedly connected to the same second connecting piece, the inner surface of the first connecting piece is movably connected to a bolt, and the outer surface of the bolt is threadedly connected to a nut.
