Description

Technical Field

[0001] The utility model relates to the technical field of sensor temperature detection, in particular to a sensor temperature detection device. Background Art

[0002] The exhaust temperature sensor is a thermistor. Its resistance changes according to the exhaust temperature, so the main control board collects different exhaust temperature values ​​based on the resistance. Exhaust temperature sensors are widely used to detect the temperature of exhaust parts such as automobile engines. The exhaust temperature directly reflects the operating status of the engine. As a result, the exhaust temperature must be very accurate when testing the engine, and there must not be a large deviation. Therefore, it is necessary to use a detection device to test the accuracy of its temperature detection before it is manufactured. The detection operation of the sensor is mainly completed by manually contacting the collection end of the exhaust temperature sensor with a heating material (such as a heating rod, etc.), and then comparing the collected temperature with the set temperature.

[0003] Publication (Announcement) No.: CN220583637U discloses an exhaust temperature sensor temperature detection device, comprising: an exhaust temperature sensor; a detection platform, the upper wall of which is fixedly mounted with a heating mechanism. Push the handle toward one side of the clamping plate, place the sensor in the contoured groove of the connecting plate, then loosen the handle, and the clamping plate is reset and clamped by the rebound force of the spring. At this time, the collection end of the exhaust temperature sensor is directly below the ceramic heating tube, and the cylinder extends to drive the connecting plate and the sensor collection position down into the ceramic heating tube. At this time, the temperature in the ceramic heating tube is collected by the exhaust temperature sensor, and then the collected temperature is transmitted to the external PLC end. By comparing it with the heating temperature of the ceramic heating tube set at the PLC end, the detection accuracy of the exhaust temperature sensor can be obtained, and the overall automatic detection operation is realized. It is not easy to get burned during the detection. In addition, the heating temperature of the ceramic heating tube is very high, which can reach the exhaust temperature of the engine exhaust pipe, and the high-temperature detection operation of the sensor can be realized.

[0004] The existing sensor detection method cannot work continuously. When replacing the sensor for detection, the machine needs to be stopped, which reduces work efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the existing sensor detection mode, which cannot work continuously and needs to be stopped when replacing the sensor for detection, thereby reducing the working efficiency. A sensor temperature detection device is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A sensor temperature detection device, comprising:

[0008] A workbench, the bottom of which is provided with four supporting legs;

[0009] A test housing is installed on the top of the workbench. The interior of the test housing is a hollow structure and is provided with a ceramic heating tube. The ceramic heating tube is connected to a temperature controller via a wire. A test hole is reserved on the outside of the test housing;

[0010] A support plate is fixedly mounted on the top of the workbench, and a rotating mechanism is mounted on the support plate;

[0011] The testing mechanism is connected to the rotating mechanism and is used for fixing the sensor and performing testing. The sensor includes a sensor head and a controller.

[0012] Preferably, the rotating mechanism includes a rotating column, which is rotatably mounted on the support plate via a bearing. A stepping motor is mounted on the outer end of the rotating column, and the stepping motor is mounted on the outer side of the support plate.

[0013] Preferably, the rotating mechanism includes a first rotating plate and a second rotating plate, and the first rotating plate and the second rotating plate are both fixedly mounted on the outside of the rotating column. Four sliding rods are slidably mounted on the first rotating plate and the second rotating plate, and the outer ends of the four sliding rods are fixedly mounted with a fixed shell for fixing the sensor head.

[0014] Preferably, the fixed shell is a round shell structure, with two wire notches provided on the fixed shell. A first bolt is threadedly connected to the fixed shell, and a first handle is installed on the outer end of the first bolt; the first bolt fixes the sensor head in the fixed shell.

[0015] Preferably, four storage shells are installed on the outer side of the second rotating plate for fixing the controller, and notches are reserved on the four storage shells. The four storage shells are threadedly connected with second bolts, and the outer ends of the four second bolts are fixedly installed with second handles; the second bolts fix the controller in the storage shell.

[0016] Preferably, the outer ends of the four sliding rods are fixedly installed with limit plates, and the outer sides of the four sliding rods are sleeved with springs, one end of the spring is fixedly installed with the limit plate, and the other end of the spring is fixedly installed with the first rotating plate; the spring provides a reset elastic force for the fixed shell through the sliding rod.

[0017] Preferably, a linear motor is fixedly mounted on the outer side of the support plate, an extrusion block is mounted on the output shaft of the linear motor, and the extrusion block cooperates with the limiting piece.

[0018] In the present invention, the beneficial effects of the sensor temperature detection device are:

[0019] The thermostat of this solution controls the temperature of the ceramic heating tube inside the test housing. Place the sensor head in the fixed housing, twist the first bolt to fix the sensor head, place the controller connected to the sensor head in the corresponding storage housing, twist the second bolt to fix it, and install four sensors in sequence. The linear motor pushes the uppermost limit plate to move through the extrusion block, and the limit plate pushes the slide bar to move. The slide bar drives the sensor head to move through the fixed housing. The sensor head passes through the test hole and contacts the ceramic heating tube, and transmits the collected temperature to the controller to observe whether the temperature is the same as the temperature displayed on the thermostat. If the temperature is the same, it means that the sensor is working normally. If the temperature is different, it means that the sensor is working abnormally.

[0020] In this solution, the linear motor drives the extrusion block to reset, and the slide rod drives the sensor head to reset through the elastic force of the spring. The stepper motor drives the first rotating plate and the second rotating plate to rotate 90 degrees through the rotating column, and the other sensor to be tested is moved to the test hole position. The sensor after the test is completed is removed and replaced. The sensor can be tested without stopping the machine, which improves work efficiency.

[0021] The utility model can install multiple sensors at one time for backup, and the sensors can be replaced by rotating for detection and use. The sensors can be detected without stopping the machine, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
