[0029] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a temperature measuring device.

[0030] like Figure 1As shown, a temperature measuring device provided by an embodiment of the present invention includes: a telescopic mechanism 1, a first rebound mechanism 2 and a temperature measuring element 3, wherein the first rebound mechanism 2 includes a first shell 21, a first elastic member 22, a first connecting member 23 and an electromagnet 24, wherein one end of the first elastic member 22 is used to be fixed on the upper wall of the inner cavity of the first shell 21, and the other end is connected to the electromagnet 24, one end of the telescopic mechanism 1 is movably connected to the heating workpiece, and the other end is connected to the first shell 21, the first elastic member 22 is connected to the fixed end of the temperature measuring element 3 through the first connecting member 23, and the end surface of the first shell 21 close to the temperature measuring element 3 is provided with a first slideway adapted to the shape of the first connecting member 23, so that the first connecting member 23 slides in the first slideway, the temperature measuring end of the temperature measuring element 3 is arranged in the same direction as the electromagnet 24, and the temperature measuring end exceeds the electromagnet 24 by a preset distance in the direction close to the object to be measured, and the electromagnet 24 is adsorbed on the object to be measured after being energized, so that the temperature measuring element 3 is abutted against the object to be measured.

[0031] Specifically, the first rebound mechanism 2 includes a first shell 21, a first elastic member 22, a first connecting member 23 and an electromagnet 24. The end of the first shell 21 close to the electromagnet 24 is an open structure to facilitate the movement of the electromagnet, and the end surface of the first shell 21 close to the temperature measuring element 3 is provided with a first slideway adapted to the shape of the first connecting member 23, so that the first connecting member 23 slides in the first slideway under the action of the electromagnet 24 and the first elastic member 22, thereby driving the temperature measuring element to move. One end of the first elastic member 22 is fixed to the upper wall of the inner cavity of the first shell 21, and the other end is connected to the electromagnet 24, that is, the first elastic member 22 is hung in the inner cavity of the first shell 21, so that the electromagnet 24 can return to its original position under the elastic force of the first elastic member 22 when the power is off, so as to continue the temperature measurement next time.

[0032] During actual temperature measurement, due to the heating process, the object to be measured is moving, and one end of the telescopic mechanism 1 is movably connected to a heating workpiece, such as a sensor or a heating bracket, and the other end is connected to the first shell 21. The first elastic member 22 is connected to the fixed end of the temperature measuring element 3 through the first connecting member 23, and the telescopic mechanism 1 can be extended and contracted, so that the temperature measuring device of the present invention can measure the temperature of the moving object to be measured. The temperature measuring device can realize movement on planes of different angles through the telescopic mechanism 1, and can realize movement in the elastic direction of the first elastic member 22 through the first rebound mechanism 2. Therefore, after the electromagnet 24 is energized and adsorbed on the object to be measured, the temperature measuring device can move with the object to be measured to expand the temperature measurement range.

[0033] like Figure 2As shown, the temperature measuring end of the temperature measuring element 3 is arranged in the same direction as the electromagnet 24. When the electromagnet 24 is not energized, the temperature measuring end exceeds the electromagnet 24 by a preset distance H in the direction close to the object to be measured. The preset distance H can be set according to the shape of the temperature measuring end of the temperature measuring element 3, for example, the shape of the thermocouple end touch sheet, and the surface state of the object to be measured. When the electromagnet 24 is energized, as shown in FIG. Figure 3 As shown, the electromagnet 24 is adsorbed on the object to be measured. At this time, the temperature measuring end of the temperature measuring element 3 and the electromagnet 24 are both in contact with the object to be measured. Since the temperature measuring end exceeds the preset distance H of the electromagnet 24 in the direction close to the object to be measured, the temperature measuring element contacts the object to be measured before the electromagnet 24, and under the action of the first elastic member 22, it strongly abuts against the surface of the object to be measured to achieve temperature measurement. After the temperature measurement is completed, the electromagnet 24 is powered off, and under the action of the first elastic member 22, the electromagnet 24 and the temperature measuring element 3 return to their original positions, returning to the position shown in FIG. Figure 2 The state shown in the figure, and the telescopic mechanism 1 returns to the non-temperature measurement state through its own extension and contraction characteristics. For example, the temperature measuring element 3 can be a temperature measuring device such as a thermocouple and a resistance thermometer. When a thermocouple is used, the red wire, i.e., the negative pole, and the yellow wire, i.e., the positive pole, must be correctly connected according to the wiring requirements of the thermocouple, and the wiring must be firm to avoid short circuit or open circuit.

[0034] In this embodiment, one end of the telescopic mechanism is movably connected to the heated workpiece, so that the telescopic mechanism can move freely with the connection between it and the heated workpiece as the base point, and then the other end of the telescopic mechanism is connected to the first shell of the first rebound mechanism, and the fixed end of the temperature measuring element is connected to the first elastic member through the first connecting member, so that the temperature measuring device can measure the temperature of the object to be measured in any direction on the heated workpiece, and the telescopic mechanism can extend and contract, and the first rebound mechanism can stretch and rebound, thereby increasing the dynamic temperature measurement range, allowing the temperature measuring device to measure the temperature of the moving object to be measured, and improving flexibility. After the electromagnet of the first rebound mechanism is energized, the electromagnet generates electromagnetism, and the object to be measured is a material that can be attracted by the magnet (for example, a cylinder made of metal), so that the electromagnet is attracted to the object to be measured. At this time, the first connecting member slides in the first slide under the action of the electromagnet and the first elastic member, and drives the temperature measuring element to move toward the object to be measured until it contacts the object to be measured, thereby realizing the temperature measurement of the object to be measured. Moreover, since the temperature measuring end and the electromagnet are arranged in the same direction, the temperature measuring end exceeds the preset distance of the electromagnet, when the electromagnet is attracted to the object to be measured, the first elastic member can drive the temperature measuring element to contact the object to be measured before the electromagnet, and forcefully abut against the surface of the object to be measured, thus ensuring good thermal contact between the temperature measuring element and the object to be measured, reducing the temperature measurement error caused by poor contact and frequent manual temperature measurement, improving the accuracy of temperature measurement, and eliminating the need to repeat meaningless temperature measurement operations, thereby improving the efficiency of temperature measurement. In addition, by controlling the power on and off of the electromagnet, the remote automatic temperature measurement can be started and closed, and there is no need to manually operate the temperature measurement equipment for temperature measurement, which is simpler and more convenient, simplifies the temperature measurement steps, reduces the time and labor intensity of manual adjustment, and improves the efficiency of temperature measurement. After the temperature measurement is completed, the telescopic mechanism and the first rebound mechanism are automatically reset, which is reusable.

Among them, the communication connection includes a wired connection and a wireless connection.
