[0001] The invention relates to the technical field of temperature measurement of a bearing induction heating mechanism, in particular to a temperature measuring device of a bearing induction heating mechanism. Background Art

[0002] The bearing induction heating mechanism is one of the heating tools for metal workpieces. It uses the principle that metal generates eddy currents in an alternating magnetic field and absorbs the generated heat to achieve rapid heating of metal workpieces. It heats various metal parts such as bearings, gears, and bushings. Bearings usually use interference fit to connect two parts. The characteristics of thermal expansion and contraction can be used to increase or decrease the diameter of the bearing assembly hole for easy assembly. The general heating temperature range of the bearing is between 80℃-100℃. Too low temperature will cause insufficient expansion of the ring, and too high temperature will cause the hardness of the bearing ring to decrease, which will affect the normal use of the bearing. Therefore, a temperature measuring device is needed to measure the temperature of the bearing induction heating mechanism to ensure the normal operation of the bearing induction heating mechanism.

The mounting frame can facilitate the fixed installation of the mounting seat, and the lifting sleeve and the supporting leg used in conjunction can be lifted and lowered according to needs, so that the temperature detection component of the equipment reaches a suitable detection height, and the walking wheel facilitates the movement of the entire equipment, thereby facilitating the temperature measurement of different positions of the steel mold.

[0005] The measuring head of the temperature measuring device mentioned above is exposed to the outside when in use and when not in use. When the entire temperature measuring device is not in use and is placed in an area with a lot of dust, the dust from the outside will come into contact with the exposed measuring head. For a long time, the temperature sensing head of the measuring head will be adhered to some dust, which will prolong the temperature sensing time of the temperature sensing head of the measuring head, and then cause the temperature measured by the measuring head to be inaccurate.

[0006] Therefore, we propose a temperature measuring device for a bearing induction heating mechanism in order to solve the above-mentioned problems. Summary of the invention

[0008] To achieve the above object, the present invention provides the following technical solution: A temperature measuring device for a bearing induction heating mechanism, comprising a supporting outer shell, and mounting rods slidably connected to the inner side wall of the supporting outer shell at equal intervals;

[0022] The upper part of the measuring head passes through the middle of the mounting plate and is connected with a cable, and the cable passes through the surface of the protective shell and is connected with a temperature data collector in the supporting shell.

[0023] Preferably, the measuring head forms a sliding structure with the protective shell through the mounting plate, and a reset spring is nested and connected to the outer side of one end of the limiting rod.

[0024] Furthermore, the stored force of the reset spring can automatically drive the measuring head to move and reset.

[0025] Preferably, a receiving groove in a circular ring structure is provided on the upper surface of the supporting outer shell, a pressing plate is slidably connected to the inside of the receiving groove, and a protrusion is fixed to the outside of the pressing plate.

[0026] Furthermore, the pressure plate is raised and lowered in the accommodating groove to squeeze the air storage bag.

[0034] Furthermore, the gas in the gas storage cavity and the gas storage airbag can flow through the connecting pipe.

[0035] Preferably, both the outer side surface and the inner side surface of the supporting outer shell are provided with grooves, the height of the grooves is equal to the height of the supporting outer shell, and the supporting outer shell is arranged in a circular ring-shaped structure.

[0036] Furthermore, by providing the grooves, the overall weight of the supporting outer shell can be reduced.

[0037] Compared with the prior art, the beneficial effects of the present invention are: the temperature measuring device of the bearing induction heating mechanism can well protect the measuring head, avoid the adhesion of dust on the surface of the measuring head and cause the temperature sensing time of the temperature sensing head to be prolonged, thereby improving the service life of the measuring head and the accuracy of temperature measurement. The specific contents are as follows:

[0038] By using the shielding ring and the sealing ring in combination, the shielding ring and the sealing ring can shield and seal the through hole when the temperature measuring device is not in use, so as to prevent external dust from entering the bottom shell through the through hole and contacting the measuring head. Therefore, when the temperature measuring device is placed in an area with a lot of dust, the measuring head can be well protected to prevent dust from sticking to the surface of the measuring head and prolonging the temperature sensing time of the temperature sensing head, thereby improving the service life of the measuring head and the accuracy of temperature measurement;

[0039] Furthermore, by sliding the mounting plate on the outside of the limit rod, the mounting plate can drive the measuring head to slide, so that the measuring head can pass through the through hole and contact the side wall of the bearing to measure the temperature. At the same time, the force stored in the reset spring can make the measuring head fit more closely with the bearing, thereby improving the accuracy of the temperature measurement.

[0040] At the same time, the six groups of measuring heads are arranged in the temperature measuring device, so that the six groups of measuring heads are evenly spaced and distributed on the inner wall of the bearing, so as to avoid the situation that a large temperature error occurs when one measuring head is used when the temperature distribution inside the bearing is uneven, thereby further improving the accuracy of the temperature measurement of the temperature measuring device;

[0041] The rotation of the threaded column drives the protrusion and the pressure plate to descend or ascend, thereby compressing the air storage bag or expanding the volume, and then facilitating the control of the gas pressure in the air storage cavity through the air storage bag. Therefore, the installation rod can be controlled to slide back and forth in the supporting outer shell body by air push, thereby synchronously adjusting the positions of the six sets of protective shells, so that the measuring heads in the protective shells can be well fitted to the inner side walls of bearings with different diameters, so that the six sets of measuring heads can perform temperature measurement operations well.

[0042] Through the control of the air-push adjustment component, not only the structure is simple, but also the weight of the entire structure is lighter. At the same time, through the opening of the groove, the weight of the supporting outer shell can be further reduced, so that the entire temperature measuring device can be well adsorbed on the bearing through the magnet block in the later stage.

[0059] The outer side and the inner side of the supporting outer shell 1 are both provided with grooves 101 , and the height of the grooves 101 is equal to the height of the supporting outer shell 1 . The supporting outer shell 1 is arranged in a circular ring shape.

[0060] Embodiment 1: The temperature measuring device in this embodiment can protect the measuring head 23, so as to prevent the temperature sensing head of the measuring head 23 from sticking to some dust and prolonging the temperature sensing time, and can improve the accuracy of the temperature measurement by the measuring head 23. For details, please refer to the attached Figure 1-Figure 6 As shown, first move the entire temperature measuring device into the working area, and then manually push the protective shell 4 downward, at this time the protective shell 4 fits in and slides downward inside the ring 13, and when the protective shell 4 moves downward, it drives the limit ring 12 to move downward together, and when the limit ring 12 moves to fit above the ring 13, the ring 13 limits the limit ring 12, so that the protective shell 4 no longer descends, and the sealing ring 141 is separated from the through hole 15, and the through hole 15 is exposed, and then the mounting plate 22 is automatically driven to slide on the outside of the limiting rod 24 through the stored force of the reset spring 25, and then the mounting plate 22 drives the measuring head 23 to slide outward, so that the outer end of the measuring head 23 can fit and contact with the inner wall of the bearing after passing through the through hole 15.

[0061] Then place the measuring head 23 in contact with the inner wall of the bearing. At this time, the outer end of the measuring head 23 is in contact with the inner wall of the bearing. At the same time, the stability of the contact between the measuring head 23 and the bearing can be improved by the force storage of the reset spring 25. At the same time, place the connecting block 3 on the upper surface of the bearing. At this time, the bearing is adsorbed by the magnet block 10, and then the entire temperature measuring device is installed on the bearing by adsorption, which is convenient for measuring the temperature of the bearing. The measuring head 23 is connected to the temperature data collector in the supporting outer shell 1 through the cable 9, so that the temperature data collector records the temperature. Since this part is the prior art, it will not be introduced in detail here. At this time, a certain amount of heat can be isolated by the insulation block 11 to avoid excessive heat affecting the adsorption work of the magnet block 10.

[0062] After the temperature measurement is completed, as shown above, the connecting block 3 is pulled upward, so that the connecting block 3 drives the magnet block 10 to separate from the bearing, and then the protective shell 4 is manually pushed upward, and then the protective shell 4 drives the bottom shell 16 to move upward together, so that the through hole 15 on the outside of the bottom shell 16 is covered by the shielding ring 14 and the sealing ring 141. Since the friction between the outer side of the protective shell 4 and the ring 13 is greater than the overall weight of the protective shell 4 and the bottom shell 16, the protective shell 4 will not be separated from the ring 13 without applying external force. At the same time, the diameter of the bottom shell 16 is greater than the diameter of the ring 13, and the protective shell 4 will not be separated from the ring 13.

[0063] Embodiment 2: In this embodiment, the positions of multiple sets of protective shells 4 can be adjusted synchronously at the same time, which is convenient to operate and has reference to the attached Figure 7-10 As shown, first, on the basis of the first embodiment, the entire supporting outer shell 1 is taken into the working area, and then as shown above, the protective shell 4 is pushed down to the adjacent Figure 4 As shown, the air intake pipe 7 is connected to the external air intake mechanism, so that the external gas enters the air storage bag 17 through the air intake pipe 7. When the entire temperature measuring device is used for a bearing with a larger inner diameter, the threaded column 6 is manually rotated, and the rotation of the threaded column 6 drives the protrusion 18 to move upward. At this time, the protrusion 18 drives the pressure plate 5 to move upward. At this time, the air storage bag 17 is not squeezed and its volume expands. At this time, the air storage bag 17 sucks out a part of the gas in the air storage chamber 20 through the connecting pipe 19, so that the mounting rod 2 in the air storage chamber 20 automatically moves outward due to the change in air pressure and the stored force of the connecting spring 21. At this time, the mounting rod 2 drives the connecting block 3 and the protective shell 4 to move outward together, so that the measuring head 23 in the protective shell 4 is in contact with the inner wall of the bearing with a larger diameter for temperature measurement, and the entire temperature measuring device is magnetically mounted on the bearing through the magnet block 10.

[0064] When the entire temperature measuring device is used for a bearing with a smaller inner diameter, as shown above, similarly, the threaded column 6 is manually rotated in the opposite direction, and the threaded column 6 drives the protrusion 18 connected to the outer thread to move downward, and the protrusion 18 drives the pressure plate 5 to move downward together, and the pressure plate 5 squeezes the air storage bag 17, and the gas in the air storage bag 17 enters the air storage chamber 20 through the connecting pipe 19, so that the mounting rod 2 is pushed inward by the air push method, and the mounting rod 2 drives the connecting block 3 and the protective shell 4 to move inward, so it is convenient to adjust the position of the protective shell 4, so that the measuring head 23 in the protective shell 4 can contact the inner wall of the bearing with a smaller diameter for temperature measurement, which is convenient to adjust, and the air push design makes the overall weight of the entire temperature measuring device lighter, which is convenient for the temperature measuring device to be stably magnetically attracted to the bearing in the later stage.

[0065] Embodiment 3: In this embodiment, the overall weight of the temperature measuring device can be further reduced, so as to improve the stability of the temperature measuring device installation. Figure 1 As shown, the grooves 101 are provided on the front and rear inner walls of the supporting outer shell 1, which can reduce the overall weight of the supporting outer shell 1, thereby further reducing the overall weight of the temperature measuring device, making it easier for the temperature measuring device to be stably installed and measure temperature, thereby completing a series of tasks.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
