Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a tool precision cutting mechanism for numerically controlled lathes. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. During the processing of workpieces, cutting operations are usually required, and the cutting accuracy of the tool needs to be guaranteed to improve the processing quality of the workpiece.

[0003] Among them, the "A CNC lathe tool precision cutting mechanism" disclosed by the application number "CN215392836U" records that the utility model discloses a CNC lathe tool precision cutting mechanism, including a base, a frame fixedly mounted on the top surface of the base, a cutting tool mounted on the frame, a mounting plate fixedly connected to the side of the frame, and a clamping mechanism and a driving mechanism provided on the mounting plate. The utility model can not only ensure the stability of the workpiece during cutting, prevent the workpiece from shaking, and ensure the cutting quality, but also fix the workpiece with a flat surface and a curved surface, expanding the scope of application of the device. Secondly, there is no need for the staff to push the workpiece by hand to move it, preventing the staff's hands from being cut by the cutting tool, and ensuring the personal safety of the staff.

[0004] However, in actual use, there are still many defects in the precise cutting mechanism of the tool for CNC lathes with similar structure. For example, when using a saw blade tool to cut the workpiece, the thickness of the saw blade is relatively thin. When it comes into contact with a harder workpiece, the saw blade will shake, causing the saw blade to shake easily during the cutting process, causing the cutting edge to be skewed, thereby reducing the cutting accuracy. Therefore, it is necessary to design a precise cutting mechanism for the tool for CNC lathes to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to provide a tool precision cutting mechanism for a CNC lathe to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precise cutting mechanism for a tool for a CNC lathe, comprising a protective cover, a support frame and a support seat, a motor is fixedly installed on the top of the support seat, a cutting disk is fixedly connected to the output end of the motor, a protective cover corresponding to the cutting disk is fixedly installed on the top of the support seat on one side of the motor, support frames are slidably installed on both sides of the inner wall of the protective cover, a movable groove is opened on the inner side of the support frame, a roller corresponding to the cutting disk is rotatably installed inside the movable groove, and a limit frame extending from the protective cover is fixedly installed on the outer side of the support frame.

[0007] The motor can drive the cutting disc to rotate, which makes it convenient to cut the workpiece. By driving the limit frame to extend into the protective cover, the limit frame can be used to drive the support frame to squeeze the cutting disc, so that the roller contacts the cutting disc. When the cutting disc rotates, the roller can rotate in the movable groove, and the roller can be used for rolling support, so that the cutting disc is not prone to shaking during cutting, and the cutting port can be kept flat, which effectively improves the cutting accuracy.

[0008] Preferably, a mounting frame is fixedly mounted on the bottom of the support seat, and a mounting hole is provided on the surface of the mounting frame. The mounting hole can be conveniently used to fix the mounting frame to a suitable position on the CNC machine tool using bolts, so as to facilitate fixing of the device.

[0009] Preferably, the protective cover is fixedly mounted on the support seat by a fixing frame, and the fixing frame is located outside the motor. The fixing frame can fix and support the protective cover, so that the protective cover can conveniently protect the cutting disc when it rotates, and avoid damage caused by contact between the cutting disc and foreign objects.

[0010] Preferably, the support frame and the protective cover are slidably mounted via a slide bar, and a stopper extending from the protective cover is fixedly mounted at the end of the slide bar. The slide bar can be used to slide to ensure the stability of the support frame, and the stopper can be used to limit the slide bar to avoid the slide bar sliding too far and causing it to fall off the protective cover.

[0011] Preferably, a threaded rotating rod is rotatably installed between the limit frame and the protective cover, and the threaded rotating rod and the limit frame are threadedly installed through a threaded sleeve. The threaded rotating rod and the threaded sleeve are threadedly engaged, and the rotation of the threaded rotating rod can drive the limit frame to move, thereby driving the limit frame to extend into the protective cover.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The utility model sets a limit frame, a support frame and a rotating roller to cooperate with each other, and can drive the limit frame to extend into the protective cover by rotating the threaded rotating rod, and can use the limit frame to drive the supporting frame to squeeze the cutting disk, so that the rotating roller contacts the cutting disk, and when the cutting disk rotates, the rotating roller can be used for rolling support, so that the cutting disk is not prone to shaking during cutting, and the cutting port can be kept flat, which effectively improves the cutting accuracy.
