Problems solved by technology

However, BT60 tools are generally large in size and heavy in weight. Using BT60 tools to process some parts with low output power and torque appears to be "overkill". Therefore, the existing BT60 tools are usually used to process large-sized parts.

Abstract

The invention discloses a shank switching device for a BT60 spindle on a lathe. The shank switching device comprises a mounting mechanism and a hollow switching shank. The switching shank is composed of a truncated cone part and a cylinder part. A switching conical hole and a switching shaft hole are formed in the switching shank. A BT50 broaching tool claw and a BT50 broaching tool claw fixing block are arranged inside the switching shaft hole. A first protective cover is arranged on the outer side of the BT50 broaching tool claw and the BT50 broaching tool claw fixing block in a sleeved mode. A second protective cover is arranged on the outer side of the first protective cover in a sleeved mode. The second protective cover is connected to the switching shank in a threaded mode. The second protective cover is provided with a conical part, wherein the conicity of the conical part is the same as that of the truncated cone part. A spring is arranged between the first protective cover and the second protective cover, and arranged on the outer side of the first protective cover in a sleeved mode. The shank switching device is convenient to install and use, enables a BT50 tool to be applied to the BT60 spindle on the lathe, reasonably expands the machining range of the lathe, reduces labor intensity of an operator when a BT600 tool is replaced, and improves machining efficiency of the lathe.

Description

Technical field [0001] The invention relates to a machine tool accessory, in particular to a tool holder adapter device of a BT60 spindle of a machine tool. Background technique [0002] For large machine tools, BT60 spindles are often used as spindles, and BT60 claws and tools are used. However, BT60 tools are generally large in size and heavy in tool weight. The use of BT60 tools to machine some parts with low power and torque appears to be "big material and small use", so the existing BT60 tools are usually used for processing large-size parts. BT50 tools are used to process smaller parts and are more commonly used in the field of machine tool processing. If BT50 tools can be applied to the machine tool BT60 spindle, it can provide more room for machine tool processing and tool selection, and rationally expand the machine tool The processing range. Summary of the invention [0003] The technical problem to be solved by the present invention is: in view of the shortcomings of ...
