Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a sensor positioning fixture. Background Technology

[0002] A sensor is a detection device that can sense the information being measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] When using a sensor, it needs to be installed in a designated position on the fixture base and secured with clamping components. However, existing sensor mounting fixtures on the market currently have the following problems:

[0007] Includes a tooling base, which has several sensor placement slots, with one sensor placed in each slot;

[0008] The tooling base is also equipped with a pressing rod and a rotating pressing block;

[0009] The pressing rod is used to press the sensor; one side of the pressing rod is hinged to the sensor insertion slot via a pressing rod fixing block.

[0010] A rotating pressure block is set on the other side of the pressing rod. The rotating pressure block is installed on the connecting block, which is installed on the tooling base. The rotating pressure block is used to press and adjust the height of the pressing rod.

[0011] Furthermore, the pressing rod is frame-shaped, with its left side positioned below the pressing rod fixing block, which is fixed to the tooling base by fixing screws.

[0012] Furthermore, a connecting block is fixedly installed within the frame of the pressing rod and on the tooling base. The connecting block is positioned between the tooling base and the rotating pressing block, and the rotating pressing block is installed on the connecting block by spring screws.

[0013] Furthermore, there are two sets of pressing rods and four sensor placement slots, with each set of pressing rods corresponding to two sensor placement slots.

[0014] Furthermore, the tooling base has through holes at its four corners, and the tooling base is installed on the customized temperature calibration device by matching bolts.

[0015] The beneficial effects of this utility model are as follows: This utility model is a sensor positioning fixture. Several sensor insertion slots are set on the fixture base. Sensors are pressed by a pressing rod, and the height of the pressing rod is adjusted by rotating the pressure block. During assembly, the fixture is installed on a customized temperature calibration device. The sensor is placed, the pressing rod is pressed down, and the rotating pressure block is rotated. The height of the rotating pressure block is adjusted by adjusting the spring screw, thus pressing and fixing the sensor. During testing, different temperature points are switched for the sensor, and a multi-functional data acquisition instrument collects the data, recording the readings of the standard sensor and comparing them with the readings of the sensor under test to achieve the specific testing process. This fixture is suitable for testing multiple sensors. For sensors of the same model, multiple sensors can be assembled and tested at once, saving manpower and time. For sensors of different models, one or more sensors can be assembled under each set of pressing rods, allowing for simultaneous testing without changing the fixture base; only slight adjustments to the spring screws are needed, improving work efficiency.

[0016] Figure 1 This is a schematic diagram of the structure of the present invention when the pressing rod is opened;

[0017] Figure 2 This is a schematic diagram of the structure of this utility model;

[0018] As shown in the figure, 1 is the tooling base, 2 is the pressing rod, 3 is the pressing rod fixing block, 4 is the connecting block, 5 is the spring screw, 6 is the fixing screw, 7 is the rotating pressing block, 8 is the sensor insertion slot, and 9 is the through hole. Detailed Implementation

[0019] As shown in the figure, this utility model discloses a sensor positioning fixture. The fixture serves as a device for positioning and fixing special sensors during the detection process. It is equipped with a customized temperature calibration device DY-BMDZ-007 (temperature controller version) to switch the sensor to different temperature points. The multi-functional data acquisition instrument DY-CTRE200-DZD collects the data and records the readings of the standard sensor and compares them with the readings of the sensor under test (four sensors) to realize the specific detection process.

[0020] This utility model includes a tooling base 1, a pressing rod 2, a pressing rod fixing block 3, a connecting block 4, and a rotating pressing block 7, wherein there are two sets of pressing rods 2 and four sensor placement slots 8, with each set of pressing rods 2 corresponding to two sensor placement slots 8. Example

[0021] Four identical sensor insertion slots 8 are cut in the middle of the tooling base 1, and four through holes 9 are provided at the four corners to facilitate the fixing of the tooling base (matching bolts are installed at the through holes to fix the tooling base on the customized temperature calibration device).

[0022] The pressing rod 2 is frame-shaped; in this embodiment, it is a rounded rectangle, as shown in the figure. A pressing rod fixing block 3 is provided on the left side of the sensor insertion slot 8. The pressing rod fixing block 3 is fixedly mounted on the tooling base 1 by two fixing screws 6, and the left side of the pressing rod 2 is pressed down by the pressing rod fixing block 3. At this time, the pressing rod 2 can rotate around the pressing rod fixing block 3, as shown in the figure. Figure 1 As shown, after it is opened, four special sensors can be placed into the slot. Press rod 2 is reset and the sensor is pressed, and locked by rotating pressure block 7 (the length of rotating pressure block 7 is greater than the width of press rod 2). Rotating pressure block 7 is fixed to connecting block 4 by spring screw 5 (spring screw combines screw and spring, can be freely screwed in and out, flexible and convenient, suitable for frequent disassembly, its outer circle is pressed with straight teeth, easy to hand tighten, and can maintain a stable connection). Connecting block 4 is fixed to tooling base 1 by UOS fixing screw 6. That is, first rotate rotating pressure block 7 to be parallel to press rod 2, flip press rod 2 to be parallel to the upper surface of tooling base 1, rotate rotating pressure block 7 around spring screw 5 to be perpendicular to press rod 2, and adjust spring screw 5 to complete the pressing operation. Example

[0023] Unlike Embodiment 1, two different sensor slots are used, one above the other, to install different types of sensors. That is, the upper pressing rod corresponds to two sensor slots of the same type, and the lower pressing rod corresponds to two sensor slots of the same type but different type.

[0024] During assembly, the fixture is mounted on a customized temperature calibration device. The sensor is placed on the device, the pressing rod is pressed down, and the rotating block is rotated. The height of the rotating block is adjusted by adjusting the spring screws to press and fix the sensor in place. During testing, different temperature points are switched for the sensor, and a multi-functional data acquisition instrument collects the data, recording the readings of the standard sensor and comparing them with the readings of the sensor under test to achieve the specific testing process. This fixture is suitable for testing multiple sensors. For sensors of the same model, multiple sensors can be assembled and tested at once (as in Example 1), saving manpower and time. For sensors of different models (as in Example 2), one or two sensors can be assembled under each set of pressing rods for simultaneous testing without changing the fixture base; only slight adjustments to the spring screws are needed, improving work efficiency. This fixture can be adapted to the shape and size of special sensors, positioning and fixing them for convenient inspection and calibration.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
