Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology, specifically relating to a novel CNC lathe tool holder. Background Technology

[0002] The lathe tool holder is an important component of a CNC lathe. Its main function is to fix and support the cutting tool, keeping it stable during workpiece machining to ensure machining accuracy and surface quality. Currently, the most common tool holders on the market are mainly for square tool holders. Although these tool holders are widely used, they have certain limitations in high-speed cutting, such as uneven tool force and vibration, which can lead to decreased machining accuracy and affect the surface finish of the workpiece.

[0003] In high-precision machining scenarios, many workpieces require the use of circular tool holders because circular tool holders can distribute cutting forces more evenly during rotation, thereby reducing vibration and improving machining stability. However, existing tool holders are generally designed for tool holders of specific shapes and are not compatible with tool holders of different specifications and shapes. Changing tools usually requires replacing the entire tool holder, which not only increases machining preparation time but also increases equipment costs.

[0004] Furthermore, during turning, polishing of the outer cylindrical surface is often necessary to further improve the surface quality of the workpiece using abrasive belts or sandpaper. However, existing tool holders typically lack a dedicated abrasive belt fixing structure, requiring operators to hold the abrasive belt by hand for polishing, which affects machining efficiency and poses certain safety hazards. Therefore, the market urgently needs a CNC lathe tool holder that can be used with tool holders of various shapes and has an abrasive belt fixing function to improve machining accuracy, reduce tool change time, and enhance operational safety. Utility Model Content

[0013] As a fifth preferred embodiment of this utility model, the body is made of 45# steel forgings.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model adopts a split dovetail slider to fix the tool holder, which is firmly and stably connected to the lathe tool post and is not easy to loosen, thereby ensuring that the tool remains stable during high-speed cutting, reducing machining errors caused by vibration, and significantly improving the dimensional accuracy and surface finish of the workpiece.

[0015] 2. The tool holder is designed with a central hole, which can directly mate with the prototype tool holder. It can also be used with square, round and conical tool holders through the intermediate sleeve, so as to realize the quick change of different specifications of tools, reduce auxiliary time, greatly improve production efficiency and meet diverse processing needs.

[0016] 3. A fixture for fixing the sanding belt is added above the main body of this utility model to ensure that the sanding belt is firmly fixed, which facilitates the outer circle polishing of the workpiece during the processing, effectively improving the surface quality of the product, while ensuring safe and convenient operation.

[0017] 4.
