Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a high-precision cutting tool wear monitoring device for ultra-precision machining. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing, also known as cutting tools. The vast majority of cutting tools are machine-made, but there are also hand-made ones. Since the cutting tools used in mechanical manufacturing are basically used to cut metal materials, the term "cutting tools" is generally understood to refer to metal cutting tools. Cutting tools for cutting wood are called woodworking tools. There is also a special type of cutting tools used for geological exploration, well drilling, and mine drilling, which are called mining tools.

[0003] As disclosed in the publication number CN212600641U, a real-time monitoring device for tool wear is disclosed. The utility model discloses a real-time monitoring device for tool wear, including a side plate and a camera, wherein a threaded hole is provided on the side plate, and the camera is fixedly connected to the top of the second support rod. The real-time monitoring device for tool wear is provided with a through slot, a through hole, a connecting rod, a first bearing, a first bevel gear, a second bevel gear, a threaded rod and an internal threaded barrel. According to the trajectory of tool movement, the connecting rod is rotated, and the connecting rod drives the first bevel gear to rotate under the action of the first bearing. While the first bevel gear drives the threaded rod to rotate through the second bevel gear, since the cross-sectional shape of the through slot in top view is circular, and the cross-sectional shape of the internal threaded barrel in top view is square, and the diameter of the cross-sectional shape of the through slot in top view is equal to the length of the diagonal line of the cross-sectional shape of the internal threaded barrel in top view, the internal threaded barrel will not rotate with the rotation of the threaded rod, so that the internal threaded barrel can move in the through slot, thereby adjusting the left and right position of the camera, so as to facilitate the detection of tool wear.

[0004] Due to the diversity of tool wear monitoring methods, each method has its unique advantages and scope of application. The above-mentioned patent mainly detects tool wear through a camera. When a sensor is selected as a tool wear detector, most of the existing electronic components such as sensors are concentrated in the tool handle, and the original tool handle structure is modified, resulting in serious damage to the classic tool handle structure designed by professional tool manufacturers. The strength and stiffness of the structure are significantly reduced, making it difficult to meet the processing requirements under heavy cutting loads. In addition, the modified intelligent tool handle has poor universality and cannot measure signals of multiple models with the same monitoring device. Utility Model Content

[0023] Specifically, support rings 38 are fixedly connected to both sides of the gear 34 , one side of the support ring 38 is rotatably connected to the fixing ring 31 , and the threaded rod 33 is located in the inner cavity of the support ring 38 .

[0024] In this embodiment, the support ring 38 is provided to support the gear 34 and ensure the stability of the gear 34 when rotating.

[0025] Specifically, one side of the clamping block 35 is fixedly connected to two guide rods 311 , one end of the guide rod 311 penetrates into the inner cavity of 32 and is slidably connected to the fixing ring 31 , and the threaded rod 33 is located between the two guide rods 311 .
