Description

Technical Field

[0001] This application relates to the field of temperature detection equipment for production lines, and more specifically, to a laser-assisted calibrated temperature probe. Background Technology

[0002] In the air cushion type continuous heat treatment production line, the temperature of the strip is detected by an infrared temperature probe at the outlet of the pre-aging furnace. According to the relative position of the installation point of the temperature probe and the outlet of the strip, there are fixed installation angle requirements for the outlet temperature probe.

[0003] The existing technology is an angle ruler calibration method based on the angle of the drawing. Its core is to measure the angle between the probe and the surface of the strip by using an angle ruler. During installation, the angle of the infrared temperature measuring probe is adjusted to force alignment with the theoretically designed 20° incident angle.

[0004] The method has the following significant drawbacks: the angle ruler measurement relies on the technician's experience, and there are parallax errors (such as the angle ruler not being parallel to the probe mounting surface) and reading errors, which can lead to an initial installation angle deviation of up to ±1.5°; the accuracy of infrared temperature measurement depends on the alignment of the probe with the target temperature measurement point, but the existing technology can only measure the overall angle of the probe and cannot intuitively observe whether the infrared radiation path actually covers the temperature measurement point.

[0005] In conclusion, improving the angle adjustment accuracy of temperature probes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a laser-assisted calibration temperature probe, which effectively improves the accuracy and ease of operation when adjusting the angle of the temperature probe.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A laser-assisted calibration temperature probe includes a temperature probe head, a fixed base, and an adjustment mounting base. The adjustment mounting base and the fixed base are movably connected, and a locking element is provided between the adjustment mounting base and the fixed base to fix them relative to each other. The temperature probe head is mounted on the adjustment mounting base. The probe also includes a laser lamp, which is fixed relative to the temperature probe head. The orientation of the temperature probe head is parallel to the orientation of the laser lamp.

[0009] Preferably, the laser lamp and the temperature probe are detachably connected, and the axis of the beam emitted by the laser lamp and the axis of the emitting end of the temperature probe are coincident.

[0010] Preferably, it also includes a relay adapter, wherein the emitting end of the temperature probe is provided with an external thread structure, and the end of the laser lamp away from its emitting end is also provided with an external thread structure. The relay adapter includes a first connecting part and a second connecting part that are coaxial with each other. The radial dimension of the first connecting part is larger than the radial dimension of the second connecting part. The first connecting part is threadedly connected to the temperature probe, and the second connecting part is threadedly connected to the laser lamp.

[0011] Preferably, the adjusting mounting base and the fixed base are rotatably connected, with the rotation axis perpendicular to the orientation of the temperature probe. The locking member is used to apply a pulling or pushing force to the adjusting mounting base, thereby increasing the friction between the adjusting mounting base and the fixed base.

[0012] Preferably, a mating shaft is rotatably mounted on the adjusting mounting base, the axis of the mating shaft coincides with the rotation axis of the adjusting mounting base, the locking element is a locking bolt, the locking bolt and the mating shaft are coaxially threadedly connected, and the head of the locking bolt abuts against the side of the fixing seat opposite to the adjusting mounting base.

[0013] Preferably, a limiting plate is coaxially provided at the end of the mating shaft away from the screw head of the locking bolt. The limiting plate is located on the side of the adjusting mounting seat away from the fixed seat, and the radial dimension of the limiting plate is larger than the radial dimension of the mating shaft.

[0014] Preferably, a thrust bearing is sleeved on the mating shaft, and the opposite sides of the thrust bearing abut against the limiting plate and the adjusting mounting seat, respectively.

[0015] Preferably, the adjusting mounting base has multiple anti-slip ribs fixedly connected to the side facing the fixed base, the length direction of the anti-slip ribs is radial to the mating shaft, and the anti-slip ribs abut against the fixed base.

[0016] Preferably, the first connecting part includes a threaded part and a detection part that are coaxially rotatably connected to each other, the threaded part is threadedly connected to the temperature probe, and the detection part and the second connecting part are integrally formed.

[0018] The laser-assisted calibration temperature probe provided in this application has a temperature probe mounted on an adjustment mount. The adjustment mount and the fixed mount can move relative to each other to change the angle of the temperature probe. When the laser lamp is turned on, it emits a visible beam. Since this beam is parallel to the direction of the temperature probe, it provides a simulation of the actual detection direction of the temperature probe. By adjusting the adjustment mount according to the point of impact and trajectory of the beam, the accuracy of the angle adjustment of the temperature probe will be greatly improved. After the angle is adjusted to the correct position, the adjustment mount and the fixed mount can be fixed relative to each other by a locking device. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

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.

An embodiment of this application discloses a laser-assisted calibration temperature probe.

[0028] The core of this application is to provide a temperature probe for laser-assisted calibration.

[0029] Please refer to Figure 1 .

[0030] The laser-assisted calibration temperature probe provided in this application includes a temperature probe head 1, a fixed base 2, and an adjustment mounting base 3. The fixed base 2 is installed on the frame of the production line. The adjustment mounting base 3 is movably connected to the fixed base 2. The temperature probe head 1 is installed on the adjustment mounting base 3. When the adjustment mounting base 3 moves relative to the fixed base 2, the detection angle of the temperature probe head 1 on it is also adjusted.

[0031] The temperature probe 1 is an infrared temperature measurement device. The probe also includes a laser lamp 5, which is fixed relative to the temperature probe 1. The orientation of the temperature probe 1 is parallel to the orientation of the laser lamp 5. The laser lamp 5 emits a visible beam, meaning its emitted visible beam is parallel to the infrared detection path of the temperature probe 1. Therefore, this beam provides a simulation of the actual detection direction of the temperature probe 1. By adjusting the mounting base 3 according to the beam's landing point and trajectory, the accuracy of the temperature probe 1's angle adjustment is greatly improved, thus avoiding the large errors inherent in manual angle adjustment.

[0032] A locking element is provided between the adjusting mounting base 3 and the fixed base 2 to fix them relative to each other. After the angle of the temperature probe 1 is adjusted to the correct position, the adjusting mounting base 3 and the fixed base 2 are fixed relative to each other by the locking element, and the angle adjustment of the temperature probe is completed.

[0033] The laser-assisted calibration temperature probe provided in this application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0034] In one specific implementation, reference is made to... Figure 1 .

[0035] Specifically, the laser lamp 5 and the temperature probe 1 are detachably connected. The laser lamp 5 is located on one side of the emitting end of the temperature probe 1, and the beam emitted by it coincides with the axis of the emitting end of the temperature probe 1.

[0036] Therefore, the beam emitted by laser lamp 5 can be directly regarded as a visual representation of the infrared radiation emitted by temperature probe 1, allowing for more precise adjustments to temperature probe 1 in this state. Removing laser lamp 5 after adjustment does not affect the normal use of temperature probe 1.

[0037] Based on the above embodiments, refer to Figure 1 .

[0038] Specifically, it also includes a relay adapter 4. The transmitting end of the temperature probe 1 has an external thread structure, and the end of the laser lamp 5 furthest from its transmitting end also has an external thread structure. The thread size of the temperature probe 1 is larger than that of the laser lamp 5. The relay adapter 4 is cylindrical and includes a first connecting part 41 and a second connecting part 42 that are coaxial with each other. The radial dimension of the first connecting part 41 is larger than that of the second connecting part 42. The first connecting part 41 is threadedly connected to the temperature probe 1, and the second connecting part 42 is threadedly connected to the laser lamp 5. Through the connecting action of the relay adapter 4, the temperature probe 1 and the laser lamp 5 achieve a coaxial and detachable connection.

[0039] Based on the above embodiments, refer to Figure 1 and Figure 2 .

[0040] Specifically, the adjusting mounting base 3 and the fixed base 2 are rotatably connected, with the axis of rotation being a horizontal line perpendicular to the orientation of the temperature probe 1. A locking element applies a pulling or pushing force to the adjusting mounting base 3, with the direction of the pulling or pushing force parallel to the axis of rotation of the adjusting mounting base 3. This increases the contact force between the adjusting mounting base 3 and the fixed base 2, thereby increasing the friction between them and making it less prone to relative movement, thus maintaining relative stability.

[0041] Based on the above embodiments, refer to Figure 1 and Figure 2 .

[0042] Specifically, the mounting base 3 is rotatably provided with a mating shaft 31, the axis of which coincides with the rotation axis of the mounting base 3, and the mating shaft 31 is the rotating shaft of the mounting base 3.

[0043] The locking component is a locking bolt 34, which is coaxially threaded with the mating shaft 31. The threaded head of the locking bolt 34 abuts against the side of the fixing seat 2 away from the adjusting mounting seat 3. When the locking bolt 34 is tightened, the locking bolt 34 generates an axial tensile force on the mating shaft 31, which is also transmitted to the adjusting mounting seat 3, thereby realizing the function of the locking component.

[0044] Specifically, a limiting plate 32 is integrally formed on the end of the mating shaft 31 away from the screw head of the locking bolt 34. The limiting plate 32 is located on the side of the adjusting mounting seat 3 away from the fixed seat 2. The radial dimension of the limiting plate 32 is larger than the radial dimension of the mating shaft 31. That is, when the mating shaft 31 is under tension, the limiting plate 32 transmits this tension to the adjusting mounting seat 3 through its own abutment and limiting effect. The existence of the limiting plate 32 also prevents the mating shaft 31 from detaching from the adjusting mounting seat 3.

[0045] Based on the above embodiments, refer to Figure 2 .

[0046] Specifically, a thrust bearing 33 is fitted onto the mating shaft 31, with its opposite sides abutting against the limiting plate 32 and the adjusting mounting seat 3, respectively. After the adjusting mounting seat 3 is swung to the correct angle with the locking bolt 34 loose, the locking bolt 34 must be tightened to fix it. When the locking bolt 34 applies tension to the mating shaft 31 through its threaded structure, the mating shaft 31 is also subjected to torque. The thrust bearing 33 can intercept the torque between the adjusting mounting seat 3 and the limiting plate 32, reducing the impact of the rotation of the locking bolt 34 on the angle of the adjusting mounting seat 3.

[0047] Based on the above embodiments, refer to Figure 2 and Figure 3 .

[0048] Specifically, multiple anti-slip ribs 35 are fixedly connected to the side of the adjusting mounting base 3 facing the fixed base 2. The length direction of the anti-slip ribs 35 is radial to the mating shaft 31. After tightening the locking bolt 34, the anti-slip ribs 35 will abut against the fixed base 2, which greatly increases the friction between the adjusting mounting base 3 and the fixed base 2, and improves the stability of the adjusting mounting base 3 relative to the fixed base 2. In this embodiment, the anti-slip ribs 35 and the adjusting mounting base 3 are integrally formed, and there are six anti-slip ribs 35 arranged in a circular array around the rotation axis of the adjusting mounting base 3.

[0049] In another implementation, refer to Figure 1 and Figure 4 .

[0050] Specifically, the first connecting part 41 includes a threaded part 411 and a detection part 412 that are coaxially rotatably connected to each other. The threaded part 411 has an internal thread structure for threaded connection with the temperature probe head 1. The detection part 412 is located on the side of the threaded part 411 facing the second connecting part 42. The detection part 412 and the second connecting part 42 are integrally formed. There is a large frictional force between the threaded part 411 and the detection part 412, and the threaded part 411 and the detection part 412 will not rotate relative to each other without the application of torque.

[0051] After installing the relay adapter 4 and laser lamp 5 on the temperature probe head 1, the laser lamp 5 should be turned on first, and the detection unit 412 should be rotated to observe whether the beam and the light spot at the end of the beam are offset. If offset occurs, it means that the coaxiality of the relay adapter 4 and the temperature probe head 1 is low. Under this condition, the angle adjustment will be less accurate and needs to be adjusted as appropriate.

[0052] An eccentric detection mark 43 is provided on the side wall of the detection unit 412. The eccentric detection mark 43 is used to provide a visual display of the real-time rotation angle of the detection unit 412 and the relative angle between the threaded part 411 and the detection unit 412 during the above calibration process, thereby improving the convenience of the calibration process.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0054] The above provides a detailed description of a laser-assisted calibration temperature probe provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
