Their stable and reliable installation and positioning are crucial. With technological advancements, various sensors, such as vision sensors, laser sensors, temperature sensors, and pressure sensors, have been widely used in a variety of industrial equipment, including automated machining centers, for real-time monitoring, control, and optimization of production processes.

[0003] While traditional sensor mounting methods, such as bracket mounting and connecting arm mounting, meet basic sensor installation requirements to a certain extent, they often face numerous challenges in specific application scenarios, such as within automated machining centers, especially for high-precision, high-sensitivity devices like tool monitoring vision sensors. The limited space within machine tools, coupled with the vibration and impact generated by tool movement and cutting operations, requires the sensor mounting structure to not only provide high-precision positioning capabilities but also possess sufficient stability and durability to withstand harsh working conditions.

[0004] Although existing invention patents such as "A Temperature Sensor Fixing Structure" (CN221147868U), "A Torque Sensor Fixing Structure" (CN220435958U), and "A Machine Tool Spindle Vibration Test Sensor Fixing Device" (CN202994287U) attempt to address the sensor fixing problem through specialized structural designs, these solutions still have limitations. For example, they fail to effectively overcome the strong impact generated by cutting within the machine tool, or still require drilling holes in the machine tool for installation, which does not meet the requirements of non-destructive installation.

[0019] Furthermore, an assembly portion is provided at one end of the fixing ring close to the adjustable ring sleeve, the assembly portion protrudes from the surface of the mechanism body, and the fastener is passed through the assembly portion.

[0023] Furthermore, the surface of the mechanism body is also provided with outwardly convex anti-slip ridges and / or inwardly concave anti-slip grooves.

[0024] By adopting the above solution, the anti-skid edges and / or anti-skid grooves can provide an anti-skid effect to facilitate assembly, while increasing the heat dissipation area, improving the heat dissipation effect, and also achieving an installation effect and enhancing the aesthetics.

[0025] Furthermore, the fastener is a bolt, and / or the adjusting member is a bolt.
