DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Example 1

[0032] Reference Figure 1, a spindle bearing temperature measuring device, comprising:

[0033] The fixing assembly 1 is used to fix the temperature measuring mechanism on the main shaft bearing. The fixing assembly 1 can be customized according to the specific structure and size of the main shaft bearing, and the temperature measuring mechanism is firmly fixed on the main shaft bearing to ensure the accuracy and stability of the temperature measurement.

[0034] The temperature measuring mechanism is connected to the main shaft bearing and the control terminal respectively. In this embodiment, the temperature measuring mechanism includes: a temperature measuring component 2, a transmission component 3, and a second connecting component 5. The temperature measuring component 2, the transmission component 3, and the second connecting component 5 are connected in sequence, with the temperature measuring component 2 connected to the main shaft bearing and the second connecting component 5 connected to the control terminal. The temperature measuring component 2 is in direct contact with the main shaft bearing and is used to measure the bearing temperature. A high-precision sensor such as a thermistor, thermocouple, or infrared temperature measuring element can be used. The transmission component 3 is responsible for transmitting the temperature signal collected by the temperature measuring component to the control terminal. The transmission component 3 can be a cable with good signal transmission performance and anti-interference ability. The protective component 4 is wrapped around the outside of the transmission component 3 to provide additional protection to prevent the cable from wear, breakage, or being affected by the external environment. In this embodiment, a corrugated tube is used as the protective component, which is flexible and corrosion-resistant. The second connecting component 5 is used to connect the transmission component 3 to the control terminal to achieve reliable signal transmission. In this embodiment, the second connecting component can be a tubular pre-insulated terminal for easy installation and maintenance.

[0035] In this embodiment, the protective assembly 4 wraps around the transmission assembly 3 and is provided with a first fastening assembly 6 and a second fastening assembly 7 at each end. A third fastening assembly 8 is provided at the connection between the transmission assembly 3 and the second connecting assembly 5. The first fastening assembly 6, the second fastening assembly 7, and the third fastening assembly 8 can all be heat shrink tubing to ensure a secure connection between the transmission assembly and the protective assembly, preventing loosening or falling off.

[0036] In this embodiment, a grounding component 9 is provided on the transmission component 3. The grounding component 9 can be a grounding device such as a grounding wire clamp, a grounding ring or a grounding bolt. The grounding component 9 effectively grounds the shielding layer of the signal cable to eliminate external electromagnetic interference and improve the stability of signal transmission.

[0037] The control terminal receives and processes temperature signals from the temperature measuring mechanism. Based on a preset temperature monitoring program, it determines whether the spindle bearing temperature is abnormal and triggers appropriate alarms and shutdowns. The control terminal receives and processes temperature signals from the temperature measuring mechanism, determines whether the spindle bearing temperature is abnormal based on preset thresholds, and triggers appropriate alarms and shutdowns. The built-in temperature monitoring program monitors the spindle bearing temperature in real time. When the temperature exceeds the preset threshold, it displays an alarm message through an audible and visual alarm, a human-machine interface, and controls the unit to shut down. It also records historical temperature data, providing fault diagnosis and parameter setting capabilities.

[0038] In this embodiment, the working process of the spindle bearing temperature measuring device is as follows: install the fixing component 1 onto the spindle bearing seat and reserve a sensor mounting hole; install the temperature measuring component 2 into the sensor mounting hole to ensure close contact with the spindle bearing; connect the temperature measuring component 2 with the transmission component 3, and then insert the transmission component 3 into the protective component 4; use the fastening component to fix the two ends of the protective component 4 and the connection with the second connecting component 5; connect the second connecting component 5 to the control terminal to complete the access and shielding grounding of the signal cable; set a temperature monitoring program in the control terminal, including preset thresholds, alarm logic and shutdown instructions; when the system is running, the temperature measuring mechanism collects the spindle bearing temperature in real time and transmits it to the control terminal through the transmission component; the control terminal determines whether the spindle bearing temperature is abnormal based on the received temperature signal, and triggers corresponding alarm and shutdown operations.

[0039] Example 2

[0040] Based on Example 1, refer to Figure 2 In this embodiment, the fixing assembly 1 is integrally connected to the spindle bearing. A mounting hole 101 is provided on the fixing assembly 1, and the temperature measuring end of the temperature measuring mechanism is disposed within the mounting hole 101. Apply an appropriate amount of thermal grease to the temperature measuring end of the temperature measuring mechanism, and then install the temperature measuring end of the temperature measuring mechanism within the mounting hole 101. Multiple mounting holes 101 can be provided depending on actual conditions. The temperature measuring mechanism has several temperature measuring ends, each of which is connected to a corresponding temperature measuring end. Use a marker to mark each temperature measuring end for ease of maintenance and inspection. The angle θ between the mounting hole 101 and the horizontal vertical line can be 30°±5°.

[0041] In this embodiment, an electric drill can be used to drill a hole in the designated position on the spindle bearing seat. Use a blind hole with a diameter of 1.5 mm and a depth of 70 to 75 mm as mounting hole 101. Maintain the hole's verticality and positional accuracy. Use an M12 x 1.5 tap to tap the blind hole, maintaining a depth between 15 and 20 mm. Ensure the tap is stable during tapping to avoid damaging the threads. Use a clean cloth or vacuum cleaner to remove debris such as iron filings and paint residue generated during drilling and tapping, ensuring the work area is clean and free of impurities. Inspect the hole for any remaining metal chips and ensure it is smooth and unobstructed.

[0042] Example 3

[0043] Based on Example 1 and Example 2, refer to Figure 3 In this embodiment, the temperature measuring component 2 includes: a temperature measuring end 201 and a first connecting component 203. The temperature measuring end 201 is connected to the main shaft bearing, and the first connecting component 203 is respectively connected to the temperature measuring end 201 and the transmission component 3.

[0044] In this embodiment, the temperature measuring terminal 201 directly contacts the main shaft bearing to sense the bearing temperature. The temperature measuring terminal 201 is embedded with a temperature sensor that accurately measures and converts temperature signals. The elastic component 202, positioned between the temperature measuring terminal 201 and the first connecting component 203, acts as a buffer and shock absorber. Made of a spring or other elastic material, the elastic component 202 absorbs impact forces generated by unit vibration, ensuring the stable operation of the temperature measuring terminal and the temperature sensor. The first connecting component 203 acts as a bridge between the temperature measuring terminal 201 and the transmission component 3, responsible for stably transmitting the temperature signal to the subsequent processing unit. The first connecting component 203 is designed with an interface that matches the temperature measuring terminal 201 and the transmission component 3, ensuring a secure connection and reliable signal transmission. During unit operation, vibrations can directly affect the stability of the temperature measuring terminal, and thus the accuracy of temperature measurements. The elastic component, through its elastic properties, effectively absorbs vibration energy, maintaining the stability of the temperature measuring terminal. When the spindle bearing undergoes slight deformation due to temperature changes, the elastic component can adaptively adjust its length and shape to ensure that the temperature measuring end is always in close contact with the bearing surface, thereby improving the accuracy of temperature measurement.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
