Technical Field

[0001] This application relates to the field of sensor testing technology, specifically to a sensor adjustment fixture. Background Technology

[0002] Existing sensor adjustment fixtures require the use of specialized jigs, such as micrometers, to adjust the sensing distance. While existing micrometers are suitable for laboratory environments, they are cumbersome to use in testing sites. Furthermore, they require sterilization and drying when brought into the factory. Fixtures like micrometers are prone to detection distortion, which can adversely affect the sensor's test results. Utility Model Content

[0003] In view of this, this application provides a sensor adjustment fixture, which uses a stepped feeler gauge to pre-set the distance between the sensor and the second support plate, and then removes the stepped feeler gauge to test the sensor sensitivity.

[0022] This application provides a sensor adjustment fixture. By using a stepped feeler gauge to pre-set the distance between the sensor and the second support plate, the stepped feeler gauge is then removed before testing the sensor sensitivity. This application has a simple structure and can quickly install and remove the sensor in the first through hole and preset the required gap, thereby improving testing efficiency and accuracy.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1-5 As shown, the sensor adjustment fixture provided in this application includes: The support part 1 includes a first support plate 11, a second support plate 13, and a connecting part 12. The first support plate 11 and the second support plate 13 are arranged parallel to each other. The connecting part 12 connects the first support plate 11 and the second support plate 13. The connecting part 12 can form a U-shape or an H-shape with the first support plate 11 and the second support plate 13. The first support plate 11 is provided with a first through hole 111. The sensor can be inserted into the first through hole 111. The length direction of the sensor is consistent with the axial direction of the first through hole 111. The sensor can move axially relative to the first through hole 111. The stepped feeler gauge 3 includes a stepped surface and a flat surface. When the flat surface is attached to the side of the second support plate 13 facing the first support plate 11, the end of the sensor can abut against the stepped surface. The position of the stepped feeler gauge 3 relative to the second support plate 13 can be adjusted so that it corresponds to the sensor passing through the first through hole 111. Specifically, when the flat surface of the stepped feeler gauge 3 is attached to the side of the second support plate 13 facing the first support plate 11, the sensor can abut against the stepped surface of the stepped feeler gauge 3. It is only necessary to convert the required gap into the stepped surface of the stepped feeler gauge 3 of the corresponding size, so as to use the feeler gauge to preset the gap between the end of the sensor and the second support plate 13. Therefore, it is only necessary to correspond the value of the preset gap between the end of the sensor and the second support plate 13 to the corresponding section of the stepped feeler gauge 3, and then set the section to correspond to the position of the first through hole 111. A fixing device is provided on the support part 1 and can fix the stepped feeler gauge 3 relative to the second support plate 13.

[0025] This application achieves the purpose of testing sensor sensitivity by pre-setting the distance between the sensor and the second support plate 13 (i.e., the sensing object) using a stepped feeler gauge 3, then removing the stepped feeler gauge 3 and adjusting the sensor sensitivity knob. This application has a simple structure and can quickly install and remove the sensor in the first through hole 111, and test the sensor sensitivity, thus improving testing efficiency and accuracy.

[0026] In a preferred embodiment, the sensor is interference-fitted with the first through hole 111.

[0027] In this embodiment, the sensor is interference-fitted with the first through hole 111. It is only necessary to insert the sensor into the first through hole 111 and adjust the position of the sensor in the first through hole 111, that is, adjust the depth of the sensor in the first through hole 111. There is no need for fastening with connecting parts. This fixing method has a simple structure. However, when using the sensor adjustment fixture to test different sensors, the sensor is prone to loosening after being inserted and removed repeatedly in the first through hole 111.

[0028] In a preferred embodiment, a first nut is circumferentially fitted onto the sensor. The first nut is threadedly engaged with the sensor and can abut against the side of the first support plate 11 facing the second support plate 13.

[0029] To better fix the sensor relative to the support 1, a first nut is fitted around the outer periphery of the sensor. The first nut abuts against the side of the first support plate 11 facing the second support plate 13. When it is necessary to adjust the distance between the end of the sensor and the second support plate 13, the first nut is pressed on the first support plate 11, and then the sensor is screwed in or out.

[0030] Furthermore, a second nut is also fitted around the sensor circumferentially. The second nut is threaded into the sensor and abuts against the side of the first support plate 11 opposite to the second support plate 13. The first nut and the second nut abut against the two sides of the first support plate 11 respectively, which can better fix the sensor relative to the first support plate 11 and reduce the slight wobbling of the sensor relative to the first support plate 11.

[0031] In a preferred embodiment, such as Figures 1-4 As shown, the connecting part 12 is arranged perpendicular to the length direction of the stepped feeler gauge 3, that is, as... Figure 1 In the middle, the connecting part 12 is located at the bottom (or the top) of the first support plate 11 and the second support plate 13. A second through hole is provided on the connecting part 12, and one end of the stepped feeler gauge 3 passes through the second through hole.

[0032] The second through hole can be used to position the step feeler gauge 3 laterally. It is only necessary to adjust the position of the step feeler gauge 3 in the length direction. Conventionally, the connecting part 12 is set at the bottom of the first support plate 11 and the second support plate 13. Of course, the connecting part 12 can also be set at the top of the first support plate 11 and the second support plate 13, but it is not easy to observe the reading of the step feeler gauge 3 in this way.

[0033] Unlike the scheme where the connecting part 12 is located at the bottom of the first support plate 11 and the second support plate 13, in another preferred embodiment, the connecting part 12 is arranged parallel to the length direction of the stepped feeler gauge 3, that is... Figure 1 In this case, the connecting part 12 is located on the side of the first support plate 11 and the second support plate 13, either on the left or the right. In this way, the stepped feeler gauge 3 does not need to be aligned and inserted into the second through hole. It can simply enter the space between the first support plate 11 and the second support plate 13 from the opening on the other side of the connecting part 12. In this case, the stepped feeler gauge 3 needs to be positioned laterally in addition to longitudinal positioning.

[0034] In a preferred embodiment, such as Figures 1-4 As shown, the fixing device is bolt 2. A third through hole is provided on the first support plate 11. Bolt 2 passes through the third through hole and is threaded into the third through hole. The tail of bolt 2 can abut against the stepped surface of the stepped feeler gauge 3.

[0035] Bolt 2 is set perpendicular to the first support plate 11 and the second support plate 13, and can be screwed in and out relative to the first support plate 11. This allows the stepped feeler gauge 3 to be clamped between the first support plate 11 and the second support plate 13 while the flat surface of the stepped feeler gauge 3 is attached to the second support plate 13, thus fixing the stepped feeler gauge 3 and allowing for fine adjustment of the clamping force. After the stepped feeler gauge 3 is fixed, the sensor is inserted into the first through hole 111 until the end of the sensor abuts against the corresponding part of the stepped feeler gauge 3, thereby achieving the preset gap between the sensor and the second support plate 13.

[0036] In addition to using bolt 2 as a fixing device, in another preferred embodiment, the fixing device can also be an elastic element. The elastic element is disposed on the side of the first support plate 11 facing the second support plate 13. That is, one end of the elastic element is fixed on the first support plate 11 and the other end faces the second support plate 13. The elastic element can be compressed in a direction perpendicular to the first support plate 11. In this way, the elastic element can rebound in a direction perpendicular to the first support plate 11 and clamp the stepped feeler gauge 3 between the first support plate 11 and the second support plate 13. In this way, the stepped feeler gauge 3 can be clamped between the first support plate 11 and the second support plate 13 while the flat surface of the stepped feeler gauge 3 is attached to the second support plate 13, thereby fixing the stepped feeler gauge 3.

[0037] In a preferred embodiment, a feeler gauge marking line is provided on the side of the second support plate 13 facing the first support plate 11.

[0038] In order to quickly locate the position of the stepped feeler gauge 3 so that it corresponds to the first through hole 111, preferably to the center of the first through hole 111, feeler gauge marking lines are set on the second support plate 13. The feeler gauge marking lines include horizontal marking lines and vertical marking lines, which form a cross so that the stepped feeler gauge 3 can quickly find the horizontal and vertical positions.

[0039] Furthermore, the stepped surface of the stepped feeler gauge 3 is provided with target size marking lines related to the sensor test size.

[0040] Setting target size marking lines means that the preset target gap value required by the sensor corresponds to the corresponding section of the stepped feeler gauge 3. Target size marking lines are made in this section and then aligned with the feeler gauge marking lines on the second support plate 13 to achieve the purpose of quick and accurate positioning.
