[0031] See also Figure 1-Figure 10The present invention provides a vacuum heat treatment furnace temperature detection device, comprising a vacuum heat treatment furnace body 11, a storage platform 12 is arranged inside the vacuum heat treatment furnace body 11, a base 13 is slidably installed between the two storage platforms 12, a first slide groove 14 is opened inside the base 13, and the first slide groove 14 is located at the center line of the base 13;

By arranging the temperature detection mechanism on the base 13, the staff can perform real-time temperature measurement around the workpiece heated by the vacuum heat treatment furnace body 11, thereby ensuring that the temperature conditions of the four surfaces of the workpiece are within the processing requirements, achieving the temperature measurement of the matrix area, and then helping to optimize the heating process, ensuring that the workpiece is heated to the standard, avoiding process defects caused by uneven temperature, and improving practicality.

[0033] The two first sliders 15 are both located in the first slide groove 14 and are slidably installed. The first bidirectional screw rod 16 is located in the first slide groove 14 and rotates. The first bidirectional screw rod 16 is threadedly installed with the first slider 15. The two connecting blocks 17 are both located at the upper end of the first slider 15 and are fixedly installed. The two fixing plates 18 are both located at the upper end of the connecting block 17 and are fixedly installed. By inserting a flat-blade screwdriver into the first flat-blade screw 29 and rotating it, the first bidirectional screw rod 16 rotates and transmits threaded transmission with the first slider 15, so that the two first sliders 15 respectively drive the limit blocks 34 to slide in the first slide groove 14 and the limit groove 33, thereby driving the two connecting blocks 17 and the first connecting bracket 25 on the fixing plate 18 to approach each other, thereby driving the first wireless temperature control detection module 27 to move, and then the distance between the first wireless temperature control detection module 27 and the workpiece can be adjusted according to the size of the workpiece, thereby improving the applicability and ensuring that there is a good detection area between the first wireless temperature control detection module 27 and the workpiece, thereby improving the detection quality.

[0034] The upper end of the base 13 is symmetrically fixed with support legs 19, each support leg 19 is respectively located at the four corners of the base 13, the two connecting blocks 17 are located between the support legs 19, the two connecting rods 21 are fixedly installed between the support legs 19, the two second slide grooves 22 are opened inside the connecting rod 21, the two second screw rods 23 are rotatably installed inside the second slide grooves 22, each second slider 24 is threadedly installed on the circumferential surface of the second screw rod 23, and each second slider 24 is slidably installed inside the second slide groove 22. The first slider 15, the first bidirectional screw rod 16, the second screw rod 23 and the second slider 24 are all made of I ncone l601 alloy (I ncone l 601 alloy is a nickel-chromium-iron based solid solution strengthening alloy with good high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding performance). By inserting a slotted screwdriver into the second slotted head 31 and rotating it, the second slotted head 31 generates a radial force to drive the second screw rod 23 to rotate, so that the second screw rod 23 and the second slider 24 are threadedly transmitted, thereby making the two second sliders 24 slide inside the second slide groove 22 and move away from or approach each other, thereby driving the second wireless temperature control detection module 28 connected to the second slider 24 to adjust to the two-quarter and three-quarter positions on the side wall of the workpiece, so that the device can adjust the position of the second wireless temperature control detection module 28 (the first wireless temperature control detection module 27 and the second wireless temperature control detection module 28 are existing structures, generally composed of a temperature sensor, a microcontroller, a wireless communication module, a power management unit, and a PCB board) according to the length of the workpiece, further improving the applicability while also improving the second wireless temperature control detection module 28 to uniformly detect the surrounding temperature of the workpiece, further improving the detection quality.

[0035] The two fixed plates 18 are symmetrically provided with square grooves 38 running through them, and each square groove 38 is slidably mounted with the connecting rod 21. The first connecting brackets 25 are fixedly mounted on the opposite ends of the two fixed plates 18, and the rotating shafts in the two first connecting brackets 25 are mounted on the first connecting brackets 25 with damping bearings. By setting the limit grooves 33 and the square grooves 38, when the first slider 15 moves, it can drive the limit block 34 to slide inside the limit groove 33, and drive the square grooves 38 on the fixed plate 18 to actively slide with the connecting rod 21, thereby providing multi-directional limits and increasing stability.

[0036] A second connecting bracket 26 is fixedly installed on the side wall of each second sliding block 24, and the rotating shaft of each second connecting bracket 26 is installed on the second connecting bracket 26 by a damping bearing. A first wireless temperature control detection module 27 is fixedly installed on the rotating shaft of the two first connecting brackets 25, and a second wireless temperature control detection module 28 is fixedly installed on the rotating shaft of each second connecting bracket 26.

[0037] A fixing block 35 is fixedly installed on the upper end of each second connecting bracket 26, and a through slot 36 is penetrated inside each fixing block 35. A connecting shaft 37 can be arranged between each through slot 36, and the two connecting shafts 37 are slidably installed with the through slot 36. By setting the fixing block 35, the staff can insert the connecting shaft 37 into the through slot 36 when facing a cube-shaped workpiece, and then complete the synchronous adjustment of a group of second wireless temperature control detection modules 28, which is convenient for operation.

[0038] Working principle:

[0039] In the first step, when the vacuum heat treatment furnace body 11 is needed to process a workpiece, the staff can open the furnace cover 32 of the vacuum heat treatment furnace body 11, and then the staff can use a forklift to take out the base 13 as a whole from the storage table 12. After the base 13 is taken out, the staff can use a sling to lift the workpiece to be processed and move the workpiece to the position between the connecting block 17 and the connecting rod 21. Then the staff can operate the sling to place the workpiece on the base 13;

[0040] In the second step, at this time, the staff can first insert a flat-blade screwdriver into the first flat-blade head 29 and rotate it, so that the first flat-blade head 29 generates a radial force to drive the first bidirectional screw 16 to rotate, and at the same time, the rotation of the first bidirectional screw 16 will be threaded with the first slider 15, so that the two first sliders 15 respectively drive the limit blocks 34 to slide in the first slide groove 14 and the limit groove 33, and approach each other at the same time, thereby driving the two connecting blocks 17 and the fixing plate 18 to approach each other, and at the same time, the movement of the fixing plate 18 will cause the square groove 38 to actively slide with the connecting rod 21, and then the staff can rotate the first wireless temperature control detection module 27 on the first connecting bracket 25 according to the shape of the front and rear sides of the workpiece, so that the probe of the first wireless temperature control detection module 27 can maintain a good measurement angle with the workpiece;

[0041] In the third step, when the staff has adjusted the first wireless temperature control detection modules 27 on the front and rear sides of the workpiece, the staff can insert a flat-blade screwdriver into the second flat-blade head 31 according to the overall length of the workpiece and rotate it, so that the second flat-blade head 31 generates a radial force to drive the second screw rod 23 to rotate, so that the second screw rod 23 and the second slider 24 are threaded, and then the two second sliders 24 slide in the second slide groove 22 and move away from or close to each other, until the staff can adjust the second wireless temperature control detection module 28 connected to the second slider 24 to a quarter of the side wall of the workpiece according to the overall length of the workpiece. The second and three-quarter positions are sufficient, and then the staff can repeat the above steps to adjust another set of second wireless temperature control detection modules 28. If the workpiece is a cube, the staff can insert the connecting shaft 37 into the through slot 36 inside the fixing block 35. Then the staff can rotate the connecting shaft 37 to drive the two fixing blocks 35 to generate radial force to drive one set of second wireless temperature control detection modules 28 to move synchronously at an angle until a good measuring angle is maintained between the probe of the square slot 38 and the surface of the workpiece. Then the staff can repeat the above steps to adjust another set of second wireless temperature control detection modules 28;

[0042] In the fourth step, if the surface of the workpiece is an inclined surface, the staff can remove the connecting shaft 37 and adjust each second wireless temperature control detection module 28 separately. Then the staff can use a forklift to move the base 13 as a whole to the inside of the vacuum heat treatment furnace body 11, and then the staff can start vacuuming. When the inside of the vacuum heat treatment furnace body 11 reaches a vacuum environment, the staff can heat the inside of the vacuum heat treatment furnace body 11. At the same time, the temperatures obtained by the probes of the four second wireless temperature control detection modules 28 and the two first wireless temperature control detection modules 27 will be fed back to the staff at regular intervals, so that the staff can make real-time adjustments according to the temperature around the workpiece.

Many modifications and variations will be apparent to those of ordinary skill in the art.
