Description

Technical Field

[0001] The invention relates to the technical field of sensor production, and in particular to a sensor axial displacement adjustment method. Background Art

[0002] In industrial automation, environmental monitoring, scientific research and many other technical fields, sensors are key devices for data collection. Their accuracy and flexibility are crucial to ensure the accuracy and reliability of measurement results. However, traditional sensor installation methods often face many challenges in practical applications.

[0003] First, traditional sensor installation methods often lack sufficient flexibility. Once the sensor is fixed, its position and orientation are difficult to adjust, which undoubtedly limits the adaptability of the sensor in different application scenarios. For example, in the field of industrial automation, sensors on the production line need to adjust their positions as the production process changes, but the traditional fixing method makes this process cumbersome and inefficient.

[0004] In addition, the traditional sensor installation method is also insufficient in terms of accuracy. Due to human errors that may exist during the installation process or the manufacturing accuracy limitations of the equipment itself, the distance and angle between the sensor and the target to be observed are often difficult to achieve the ideal accurate value. This not only affects the accuracy of the measurement results, but may also cause data deviation, thus affecting subsequent analysis and decision-making. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1 As shown, a sensor axial displacement adjustment method comprises the following steps:

[0038] S1: fix the sensor to the connecting shaft 3, fix the adjustable device equipped with the adjusting ring 5 and the limiting sleeve 2 to the connecting shaft 3, and fix the connecting shaft 3 to the fixing part 6;

[0039] S2: Adjust the horizontal height and position of the fixing portion 6 until the connecting axis 3 and the object to be observed are in the same straight line;

[0040] S3: moving the connecting shaft 3 along the axial direction of the connecting shaft 3 until the target to be observed is within the observation distance length of the sensor;

[0041] S4: applying a tangential force to the adjusting ring 5 to drive the rotation and displacement of the limiting sleeve 2 and the connecting shaft 3 until the distance between the target to be observed and the sensor reaches a preset value.

[0042] In this embodiment, a sensor bracket is provided to implement the above steps. The specific structure of the sensor bracket is as follows: Figure 2 As shown, it includes a connecting shaft 3 and a fixing part 6. The rear end of the connecting shaft 3 is connected to the sensor, and the rear end of the connecting shaft 3 is connected to an adjustable device; the rear end of the adjustable device is connected to the fixing part 6. The connecting shaft 3 serves as the axis of rotation and adjustment, and the bracket adjusts the connecting shaft 3 to achieve the purpose of adjusting the sensor.

[0043] The adjustable device includes a bearing, a limit sleeve 2 and an adjustment ring 5. The bearing is sleeved at the rear end of the connecting shaft 3. The limit sleeve 2 is sleeved on the connecting shaft 3 and abuts against the outer periphery of the bearing. The adjustment ring 5 is sleeved on the outer periphery of the limit sleeve 2 to drive the limit sleeve 2 to rotate and adjust the axial displacement of the rotating shaft. The bearing abuts against the limit sleeve 2 and supports the connecting shaft 3 on the axis, which is used to reduce the friction and wear of the connecting shaft 3 during the rotation process and improve the smoothness and accuracy of the rotation. The limit sleeve 2 is used to limit the axial movement of the connecting shaft 3 to prevent it from falling out during use, ensuring the stability and safety of the structure.

[0044] The first spring 12 is sleeved on the rear end of the connecting shaft 3, and the first spring 12 cooperates with the bearing to reduce the vibration effect. The inner ring of the limiting sleeve 2 is provided with a first retaining ring 9 and a second retaining ring 10, the first retaining ring 9 is connected to the bearing to limit the bearing, and the second retaining ring 10 is sleeved on the outer periphery of the connecting shaft 33 to limit the non-axial movement of the connecting shaft 3.

[0045] Among them, 1 to 5 anti-skid grooves are arranged on the outer side of the adjustment ring 5, which improves the applicability of the sensor bracket and is not easy to slip when making detailed adjustments to the connecting shaft 3, making the operation convenient.

[0046] The connecting shaft 3 further comprises a connecting shaft 3 disc, and the connecting shaft 3 disc is arranged in the middle of the connecting shaft 3 .

[0047] Example 2

[0048] like Figure 1 and Figure 2 As shown, a sensor axial displacement adjustment method and a sensor bracket used therein are the same as those in Example 1, except that:

[0049] The step S1 of fixing the sensor to the connecting shaft 3 includes:

[0050] The sensor is embedded in the hollow mounting hole provided at the top end of the connecting shaft 3;

[0051] This embodiment provides a specific way to fix the sensor to the connecting shaft 3: embedded fixation, which is suitable for the case where the sensor size matches the mounting hole of the connecting shaft 3, and the rear end of the connecting shaft 33 is hollow inside for mounting the sensor; in some other embodiments, threaded fixation is adopted, that is, the sensor is rotated to fix it to the threaded hole at the top of the connecting shaft 3, which is suitable for the case where the bottom of the sensor has threads and matches the threaded hole of the connecting shaft 3. Both methods ensure the stable connection between the sensor and the connecting shaft 3, which is convenient for subsequent displacement and rotation adjustment.

[0052] In this embodiment, the bearing includes a first bearing 8 and a second bearing 7. The first bearing 8 is sleeved in the middle of the connecting shaft 3 and abuts against the disc of the connecting shaft 3, and the second bearing 7 is sleeved at the rear end of the connecting shaft 3. The first bearing 8 is used to bear the axial load to ensure that the relative position between the components is stable during the axial adjustment process and reduce axial friction and wear. The second bearing 7 is mainly used to bear radial loads as a supporting component of the connecting shaft 3. A first bearing 8 and two second bearings 7 are sleeved on the connecting shaft 3. A limiting bayonet is provided at the relative position of the second bearing 7 on the inner side of the limiting sleeve 2 to limit the axial displacement of the second bearing 7 and ensure the stability of the operation of the sensor bracket.

[0053] The step S1 in which the adjustable device equipped with the adjusting ring 5 and the limiting sleeve 2 is fixed on the connecting shaft 3 includes:

[0054] A first bearing 8 and a second bearing 7 are installed on the connecting shaft 3, and threads corresponding to the first bearing 8 and the second bearing 7 are provided on the connecting shaft 3;

[0055] A limiting sleeve 2 is sleeved and installed on the outer circumference of the first bearing 8 and the second bearing 7, and threads corresponding to the limiting sleeve 2 are arranged on the first bearing 8 and the second bearing 7;

[0056] An adjusting ring 5 is sleeved and installed on the outer periphery of the limiting sleeve 2 , and a thread corresponding to the adjusting ring 5 is arranged on the limiting sleeve 2 .

[0057] The stacked installation of the first bearing 8 and the second bearing 7, the limiting sleeve 2 and the adjusting ring 5 realizes the fine adjustment function of the connecting shaft 3 in the axial and rotational directions. This structure not only increases the adjustment accuracy, but also ensures the stability and reliability of the adjustment process.

[0058] Among them, in step S1, the connecting shaft 3 is fixed to the fixing part 6, including sleeve-mounting the housing 1 on the outer periphery of the limiting sleeve 2, and the housing 1 is fixed to the fixing part 6 by screw thread, which not only enhances the stability of the connection and prevents impurities in the working process from affecting the support of the sensor bracket, but also facilitates disassembly and maintenance. The housing 1 is the basic connection part of the entire bracket, which is connected to other components and provides stable support for them. The adjustable device is set along the central axis to fix and adjust the position of related components to ensure the stability and accuracy of the entire bracket structure.

[0059] In addition, the adjustable device also includes a tail shell 4, which is arranged on the periphery of the limit sleeve 2 and abuts against the front end of the adjustment ring 5 to prevent foreign matter from entering the interior of the bracket and affecting the operation of the bracket, and improves the integrity of the bracket. A step portion is provided on the tail shell 4 near the end of the adjustment ring 5, and the adjustment ring 5 is sleeved on the outside of the step portion to prevent the tail shell 4 from excessive movement during the adjustment process.

[0060] In this embodiment, the rear end of the connecting shaft 3 is connected to the sensor, and the outer periphery of the rear end of the connecting shaft 3 is connected to an adjustable device; the rear end of the adjustable device is connected to the fixed part 6; the adjustable device is installed with a bearing, a limit sleeve 2 and an adjusting ring 5, the bearing sleeve is arranged at the rear end of the connecting shaft 3, the limit sleeve 2 is sleeved on the connecting shaft 3 and abuts against the outer periphery of the bearing, the adjusting ring 5 is sleeved on the outer periphery of the limit sleeve 2 to drive the limit sleeve 2 to rotate and adjust the axial displacement of the rotating shaft, the rear end of the connecting shaft 3 is sleeved with a first spring 12, the inner ring of the limit sleeve 2 is provided with a first retaining ring 9 and a second retaining ring 10, the first retaining ring 9 is connected to the bearing to limit the bearing, the second retaining ring 10 is sleeved on the outer periphery of the connecting shaft 3 to limit the non-axial movement of the connecting shaft 3, and the limit sleeve 2 is sleeved with an outer shell 1.

[0061] Example 3

[0062] like Figure 1 and Figure 2 As shown, a sensor axial displacement adjustment method and a sensor bracket used therein are the same as those in Example 1, except that:

[0063] Among them, in step S3, moving the connecting shaft 3 along the axial direction of the connecting shaft 3 includes rotating the portion of the connecting shaft 3 that is not mounted by the adjustable device, so that the movement of the connecting shaft 3 in the axial direction is more flexible and accurate, meeting the needs of different application scenarios. In some other embodiments, the position of the connecting shaft 3 can also be quickly adjusted by directly pushing or pulling the non-sensor mounting end of the connecting shaft 3.

[0064] Wherein, in step S4, applying a tangential force to the adjusting ring 5 to drive the rotation and displacement of the limiting sleeve 2 and the connecting shaft 3 includes:

[0065] Apply tangential force to the adjusting ring 5 in the clockwise direction to drive the rotation of the limit sleeve 2 and the connecting shaft 3 in turn, thereby reducing the distance between the target to be observed and the sensor;

[0066] A tangential force is applied to the adjusting ring 5 in the counterclockwise direction to drive the rotation of the limiting sleeve 2 and the connecting shaft 3 in turn, thereby increasing the distance between the target to be observed and the sensor.

[0067] After the sensor position is finely adjusted by the adjusting ring 5, that is, when the operating distance of the sensor is appropriate, the tangential force is stopped, and the adjustable device is provided with a first retaining ring 9 and a second retaining ring 10 for fixing the connecting shaft 3, that is, fixing the operating distance of the sensor.

[0068] The specific method of adjusting the distance between the sensor and the target to be observed by applying a tangential force to the adjustment ring 5 is clarified, and the clockwise and counterclockwise rotations correspond to the decrease and increase of the distance respectively. This method is easy to operate and has high adjustment accuracy, and is suitable for various occasions that require precise adjustment of the sensor position.

[0069] Example 4

[0070] like Figure 1 and Figure 2 As shown, a sensor axial displacement adjustment method and a sensor bracket used therein are the same as those in Example 1, except that:

[0071] In step S1, the connecting shaft 3 is fixed to the fixing part 6, including threading the fixing part 6 on the outer circumference of the connecting shaft 3, the fixing part 6 is a circular collar, and the center of the fixing part 6 is in the axial direction of the connecting shaft 3. The direct installation method simplifies the installation process and improves the installation efficiency.

[0072] Preferably, adjusting the horizontal height of the fixing part 6 in step S2 includes: adjusting the horizontal height of the fixing part 6 until the horizontal line of the circular ring passes through the center of the target to be observed, ensuring that the sensor and the target to be observed are on the same horizontal plane, thereby improving the accuracy of measurement.

[0073] Preferably, adjusting the position of the fixing part 6 in step S2 includes: adjusting the horizontal position of the fixing part 6 until the center of the circular ring coincides with the center of the target to be observed. This method ensures precise alignment between the sensor and the target to be observed, further improving the measurement accuracy.

Any changes or substitutions that can be easily thought of by any technician familiar with the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
