Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an ultra-long tool suitable for machining narrow gaps and long-distance surfaces. Background Art

[0002] The machining of narrow gaps and long-distance surfaces has always been a bottleneck in the manufacturing industry, especially when cleaning the root of the long-distance surface. In recent years, with the increasing demand for personalized products in the manufacturing industry, there are inevitably parts that cannot be completed by conventional capabilities in product design, such as narrow gaps and long-distance surfaces. In order to meet the product requirements, in most cases, R & D personnel repeatedly modify the product structure according to the actual situation on site, or manufacturing technicians continuously adjust the technical route and manufacturing method, which brings great resistance to product development, not only increasing the manufacturing cost but also extending the manufacturing cycle. This invention patent maximally solves the problems of difficult machining, low efficiency, and high cost of narrow gaps and long-distance surfaces. Summary of the Invention

[0003] In view of this, in order to solve the technical problems existing in the above technology, it is necessary to provide an ultra-long tool suitable for machining narrow gaps and long-distance surfaces.

[0004] An ultra-long tool suitable for machining narrow gaps and long-distance surfaces includes a tool body, a shank, and a tool tip; one end of the shank is detachably connected to the end of the tool body, the interior of the shank is hollow, and the tool tip is detachably installed at the other end of the shank.

[0005] Preferably, one end of the shank is provided with a connecting head, and one end of the tool body is provided with a mounting hole for installing the connecting head.

[0006] Preferably, a limiting groove is axially formed in the mounting hole, and a limiting block adapted to the limiting groove is provided on the connecting head to realize the insertion connection between the connecting head and the mounting hole.

[0007] Preferably, a threaded hole is radially formed in the tool body opposite to the limiting groove. When a ejector rod is screwed into the threaded hole, the connecting head and the mounting hole can be fastened.

[0008] Preferably, the ejector rod is threadedly connected to the limiting block.

[0009] Preferably, the tool tip and the shank are fastened by a compression screw passing through the tool tip.

[0010] Preferably, a protrusion is provided on the end face of the shank away from the connecting head, a clamping groove adapted to the protrusion is provided on the tool tip, and a through hole concentric with the clamping groove is formed through the tool tip for installing the compression screw.

[0011] Preferably, one end of the tool body away from the mounting hole is provided with an end for connecting the machine tool tool holder.

[0012] Preferably, the adapter bar and the tool body are in a conical structure.

[0013] Compared with the prior art, the ultra-long tool provided by the present utility model suitable for machining narrow gaps and long-distance surfaces includes a tool body, an adapter bar, and a tool tip; one end of the adapter bar is detachably connected to the end of the tool body, the interior of the adapter bar is hollow, and the tool tip is detachably installed at the other end of the adapter bar. The present utility model designs the whole tool into three parts: the tool body, the adapter bar, and the tool tip. Among them, the tool body is mainly used to connect the tool holder of the machine tool, and for the adapter bar part, both the rigidity and strength of the tool need to be considered, and the tool needs to be lengthened as much as possible. Therefore, this part is designed to be hollow, so that sufficient strength can still be maintained while reducing the weight, realizing the lengthening of the overall length of the tool. In this way, different styles of narrow gaps and long-distance surfaces can be machined, effectively avoiding meaningless modification of drawings by R & D personnel or repeated adjustment of technical solutions by technicians, greatly saving the manufacturing cost, and increasing the production efficiency by more than 30%.
