Description

TECHNICAL FIELD

[0001] The utility model relates to sensor fixing device technical field especially relates to a magnetic sensor fixing structure. BACKGROUND

[0002] In the field of modern industrial automation and intelligent manufacturing, sensors, as the "nerve endings" that perceive the operating state of machines and environmental information, are of paramount importance. In particular, in automatic machining tools and other high-precision, high-efficiency production equipment, sensors not only undertake the task of real-time monitoring of key parameters such as tool wear, workpiece position, temperature fluctuations, and pressure changes, but also are the key link to realize intelligent control and optimization of production processes.

[0003] Traditional sensor fixing methods, such as bracket installation and connecting arm fixation, can meet the basic installation needs in general industrial environments, but they are not satisfactory in the specific application scenario of automatic machining tools. The internal space of the machine tool is compact, and the strong vibration and impact generated by high-speed cutting operations pose high requirements on the fixing structure of the sensor. Not only does it need to achieve high-precision positioning to ensure that the sensor can accurately capture target information, but it must also have excellent stability and durability to withstand the challenges of long-term operation in harsh conditions. The industry has made many attempts and innovations to solve this problem. For example, some invention patents such as "Temperature Sensor Fixing Structure" (CN221147868U), "Torque Sensor Fixing Structure" (CN220435958U), and "Machine Tool Spindle Vibration Test Sensor Fixing Device" (CN202994287U) have been developed to optimize the fixing method of the sensor through special design structures. These solutions have improved the installation precision and stability of the sensor to some extent, but there are still obvious limitations.

[0004] Specifically, existing fixing structures often fail to effectively overcome the strong impact generated by cutting operations inside the machine tool, resulting in loosening or damage of the sensor after long-term operation. In addition, some solutions still require drilling holes on the machine tool for installation, which not only increases the installation difficulty and cost, but also may damage the overall structure of the machine tool, which does not meet the urgent needs of modern industry for non-destructive installation and easy maintenance. SUMMARY

[0005] To overcome at least one of the deficiencies of the prior art described above, the utility model provides a magnetic sensor fixing structure. The drilling problem is solved, the installation difficulty and cost are reduced, and the impact generated by cutting operations can be resisted.

[0006] The technical scheme adopted by the utility model to solve the problem is:

[0007] The application discloses a magnetic sensor fixing structure, which comprises a mechanism body, a sensor mounting sleeve arranged on one end of the mechanism body, a fastener arranged on the sensor mounting sleeve, and a magnetic element arranged on the mechanism body.

[0008] The sensor can be initially placed in the sensor mounting sleeve of the mechanism body, and the direction, angle and position of the sensor can be freely adjusted until the correct monitoring position is reached. Once the position is determined, the sensor can be fixed and locked by the fastener, ensuring the stability and accuracy of the sensor. The magnetic element can solve the problem of fixing the sensor in the machine tool. The traditional fixing methods such as drilling, screwing or gluing are not needed, so that the damage to the machine tool can be avoided, and the installation time and cost can be saved. The strong adsorption capacity of the magnetic element can ensure the stable fixation of the sensor on the machine tool surface. Even in harsh environments such as vibration, cutting oil impact, high temperature and greasy, the sensor can be effectively prevented from falling off and failing.

[0009] Further, the sensor mounting sleeve is arranged on one end of the mechanism body, and the sensor mounting sleeve is provided with an extension edge protruding from the first surface and / or the second surface.

[0010] By adopting the above scheme, the operator can easily put the sensor into the sleeve, improve the flexibility and accuracy of the sensor installation, and enhance the stability and reliability of the fixing structure.

[0011] Further, the magnetic element and the extension edge are provided with a clearance, and the fastener extends into the sensor mounting sleeve from the side of the clearance.

[0012] By adopting the above scheme, the direct interference between the fastener and the magnetic element is avoided, the fastener can work smoothly, and the magnetic element is protected from potential damage during the fastening process. The clearance provides additional space, so that the sensor can have a certain degree of freedom during installation and adjustment. This helps the operator to accurately position the sensor, so that it can face the monitored part, thereby achieving the best monitoring effect.

[0013] Further, the height of the extension edge protruding from the first surface is lower than the height of the magnetic element protruding from the first surface, and / or the height of the extension edge protruding from the second surface is lower than the height of the magnetic element protruding from the second surface.

[0014] By adopting the above scheme, it is ensured that the magnetic attraction member can directly contact the machine tool mounting surface and generate sufficient adsorption force to stably fix the mechanism body on the machine tool. Since the magnetic attraction member protrudes from the extension edge, even if there is a slight unevenness or stain on the machine tool surface, the magnetic attraction member can effectively overcome these obstacles to achieve reliable adsorption, which helps to protect the extension edge and the machine tool surface from potential damage, while reducing the difficulty and complexity of installation.

[0015] Further, a locking member is provided between the magnetic attraction member and the mechanism body, and the locking member is connected to the mechanism body through the magnetic attraction member.

[0016] By adopting the above scheme, the close cooperation between the locking member and the magnetic attraction member and the mechanism body enhances the integrity and rigidity of the entire fixing structure. This helps to reduce the deformation or loosening problems that may occur during installation and use, thereby improving the measurement accuracy and stability of the sensor.

[0017] Further, the first surface and / or the second surface of the mechanism body is provided with an assembly groove, and the magnetic attraction member is fixed in the assembly groove.

[0018] By adopting the above scheme, the design of the assembly groove makes the installation of the magnetic attraction member more accurate and stable. By embedding the magnetic attraction member in the assembly groove, it can ensure the close cooperation between the magnetic attraction member and the mechanism body, and reduce the performance degradation caused by loosening or misalignment. In addition, the assembly groove can also provide additional support for the magnetic attraction member, enhancing its ability to resist external impact and vibration, thereby prolonging the service life of the entire fixing structure.

[0019] Further, the area of the first surface is larger than the area of the second surface, the angle between the axis of the sensor mounting sleeve and the first surface is in the range of 120°-150°, and the angle between the axis of the sensor mounting sleeve and the second surface is in the range of 30°-60°.

[0020] By adopting the above scheme, a larger area can provide more stable support, enhancing the contact area between the mechanism body and the machine tool mounting surface, thereby improving the overall stability. The angle range is suitable for situations where the sensor needs to be installed at an angle to better cover or monitor a specific area, to adapt to different monitoring needs and working environments.

[0021] Further, the sensor mounting sleeve is integrally formed with the mechanism body.

[0022] By adopting the above scheme, it is ensured that the sensor mounting sleeve and the mechanism body are closely connected, avoiding performance degradation due to assembly errors or loosening, while ensuring the stability and accuracy of the sensor during installation and use.

[0023] Further, the side surface of the mechanism body is provided with an anti-skid pattern of concave or convex.

[0024] By adopting the above scheme, the friction between the mechanism body and the user's hand or other contact surface is increased, preventing accidents caused by slipping or falling during operation.

[0025] Further, the locking member is a bolt, and / or the fastening member is a bolt.

[0026] By adopting the above scheme, when the bolt is used as the locking member, it can effectively fix the magnetic member on the mechanism body. The connection strength between the magnetic member and the mechanism body can meet the working requirements, and stable fixing effect can be maintained even in harsh working conditions. When the bolt is used as the fastening member, it can extend from one side of the avoidance gap to the sensor mounting sleeve and be fixed in the mounting sleeve by thread connection or other means. Not only does it simplify the installation process and reduce the installation difficulty, but also improves the accuracy and stability of the installation.

[0027] In summary, the magnetic type sensor fixing structure has the following technical effects:

[0028] 1. The sensor is fixed to the machine tool mounting surface by the magnetic member, without the need for traditional fixing methods such as drilling, screwing or gluing, thereby avoiding damage to the machine tool equipment and saving installation time and cost;

[0029] 2. The sensor can be initially placed in the sensor mounting sleeve on the mechanism body, and the direction, angle and position of the sensor can be freely adjusted by the fastening member until the correct monitoring position is reached. This flexibility enables the sensor to more accurately capture target information, improving the accuracy of monitoring;

[0030] 3. The magnetic member has strong adsorption capacity, which can ensure the stable fixation of the sensor on the machine tool mounting surface. Even in harsh environments such as vibration, cutting oil impact, high temperature and greasy, the sensor can be effectively prevented from falling off and failing, thereby prolonging the service life of the sensor;

[0031] 4. Since the magnetic type fixing structure is easy to disassemble and reinstall, when the sensor needs to be repaired or replaced, it can be more conveniently operated, reducing maintenance cost and improving overall work efficiency. At the same time, the magnetic type fixing structure will not damage the machine tool equipment, maintaining the overall structural integrity of the machine tool, which is conducive to the long-term stable operation of the equipment.

[0046] In some embodiments, in order to facilitate the operation of the fastener 3, a clearance 5 is reserved between the magnetic attraction piece 4 and the extension edge 21, and the fastener 3 extends into the sensor installation sleeve 2 from the side of the clearance 5 through the extension edge 21. By this setting, direct interference between the fastener 3 and the magnetic attraction piece 4 is avoided, ensuring that the fastener 3 can work smoothly, and the magnetic attraction piece 4 is also protected from potential damage during the fastening process. The clearance 5 also provides additional space, allowing the sensor to have a certain degree of freedom during installation and adjustment. This helps the operator to position the sensor more accurately, ensuring that it can face the monitored part directly, thereby achieving the best monitoring effect.

[0047] In some embodiments, the extension edge 21 needs to be limited to avoid affecting the magnetic attraction effect of the magnetic attraction piece 4, therefore, the height of the extension edge 21 protruding from the first surface 11 is lower than the height of the magnetic attraction piece 4 protruding from the first surface 11, and / or the height of the extension edge 21 protruding from the second surface 12 is lower than the height of the magnetic attraction piece 4 protruding from the second surface 12, which ensures that the magnetic attraction piece 4 can directly contact the machine tool mounting surface and generate sufficient adsorption force to stably fix the mechanism body 1 on the machine tool.
