Description

Technical Field

[0001] This utility model relates to the field of micrometer technology, specifically to an adaptive temperature-compensated micrometer. Background Technology

[0002] A capacitive micrometer typically consists of a main unit and a detection head. The detection head is primarily responsible for contacting the object being measured, sensing changes in the object's size or displacement, and converting these changes into changes in capacitance. The main unit measures these changes in capacitance and converts them into corresponding electrical signals. The main unit also features a display screen to show the measurement results, allowing users to easily read the dimensions or displacement values ​​of the object being measured.

[0003] In winter, the surface temperature of metal objects is extremely low. When the detection head comes into contact with the object, the low temperature alters the material properties of the detection head. The low temperature increases the elastic modulus of the metal detection head, making the material harder and more brittle. This means that when in contact with a cold-temperature metal object, the detection head is more susceptible to minute deformations due to external forces, and these deformations may not be fully recovered, thus affecting the contact state between the detection head and the object and the measurement accuracy. To address this issue, we propose an adaptive temperature-compensated micrometer. Utility Model Content

[0022] It should be noted that when detecting metal objects in winter, the temperature probe 6 can detect the surface temperature of the metal object and transmit the data to the controller 3. When the temperature is lower than the value set by the controller 3, the controller 3 automatically starts the drive component 11, which drives the transmission component 8 to rotate, thereby simultaneously driving multiple auxiliary components 9 to rotate, and then simultaneously driving multiple heating components 10 to rotate at a certain angle, raising the heating components 10. At this time, the heating components 10 can be used to heat the surface of the metal object, so that the surface of the metal object is at a suitable temperature for temperature compensation, avoiding affecting the measurement accuracy of the detection head 2. At the same time, it can also work with the controller 3 to perform algorithm compensation on the measurement data of the capacitive micrometer body 1. The corresponding compensation amount is calculated based on the current temperature value, and the compensation amount is subtracted from the measurement value to obtain the measurement result after temperature compensation, thus performing adaptive temperature compensation. The electric heating plate 1004 adopts a foldable design, which can be used upright when needed and can be laid flat on one side of the detection head 2 when not needed, making it convenient for the storage of the detection head 2.

[0023] In a preferred embodiment, the transmission assembly 8 includes an internal gear ring 801, a plurality of equidistant connecting plates 802 mounted on one side of the outer wall of the internal gear ring 801, and a slider 803 mounted on one end of the connecting plates 802.

[0024] It should be noted here that the drive component 11 can drive the internal gear ring 801 to rotate.

[0025] In a preferred embodiment, the transfer assembly 9 includes a support plate 901, a transfer shaft 902 rotatably mounted on the outer wall of the support plate 901, a transfer gear 904 mounted on one end of the transfer shaft 902, and a transfer bevel gear 903 mounted on the other end of the transfer shaft 902.

[0026] It should be noted that the rotation of the internal gear ring 801 can drive the rotation of the transfer gear 904, which in turn drives the transfer shaft 902 and the transfer bevel gear 903 to rotate.

[0027] In a preferred embodiment, the heating assembly 10 includes two mounting plates 1001, a rotating shaft 1002 rotatably connected between the two mounting plates 1001, an adjusting plate 1003 mounted on the outer wall of the rotating shaft 1002, an electric heating plate 1004 mounted on the bottom outer wall of the adjusting plate 1003, and a driven bevel gear 1005 mounted on one end of the rotating shaft 1002.

[0028] It should be noted that the rotation of the drive bevel gear 903 can drive the driven bevel gear 1005 to rotate, which in turn drives the rotating shaft 1002 and the adjusting plate 1003 to rotate, which in turn drives the electric heating plate 1004 to rotate.

[0029] In a preferred embodiment, the drive assembly 11 includes a fixed plate 1101, an electric rotary table 1102 mounted on the top of the fixed plate 1101, a drive shaft 1103 mounted on the rotating part of the electric rotary table 1102, and a drive gear 1104 mounted on one end of the drive shaft 1103.

[0030] It should be noted that the electric rotary table 1102 can drive the drive shaft 1103 and the drive gear 1104 to rotate.

[0031] In a preferred embodiment, the electric rotary table 1102, the electric heating plate 1004, and the temperature probe 6 are all connected to the controller 3 via signal lines, and the controller 3 is connected to the internal processing system of the capacitive micrometer body 1.

[0032] It should be noted that controller 3 can control the electric rotary table 1102, the electric heating plate 1004, and the temperature probe 6.

[0033] Working principle: When inspecting metal objects in winter, the temperature probe 6 can detect the surface temperature of the metal object and transmit the data to the controller 3. When the temperature is lower than the value set by the controller 3, the controller 3 automatically starts the electric rotary table 1102, which drives the drive shaft 1103 and the drive gear 1104 to rotate, which in turn drives the internal gear ring 801 to rotate. The rotation of the internal gear ring 801 drives multiple distribution gears 904 to rotate, which in turn drives multiple distribution shafts 902 and distribution bevel gears 903 to rotate, which in turn drives multiple driven bevel gears 1005 and rotating shaft 1002 to rotate, which in turn drives multiple adjusting plates 1003 and electric heating plates 1004 to rotate, raising the electric heating plates 1004. At this time, the electric heating plates 1004 can be used to heat the surface of the metal object.

[0034] This ensures that the surface of the metal object is at a suitable temperature, performs temperature compensation, and avoids affecting the measurement accuracy of the detection head 2;

[0035] Simultaneously, it can also work with the controller 3 to perform algorithm compensation on the measurement data of the capacitive micrometer body 1. The corresponding compensation amount is calculated based on the current temperature value, and the compensation amount is subtracted from the measured value to obtain the measurement result after temperature compensation. Adaptive temperature compensation is performed. The electric heating plate 1004 adopts a foldable design, which can be used upright when needed and can be laid flat on one side of the detection head 2 when not needed, making it convenient to store the detection head 2.
