DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0027] As Figures 1-4 shown, an embodiment of the present utility model provides a temperature measuring frame for a heat treatment furnace, which includes a main body 1 and a bracket fitting 2 arranged inside the main body 1; the main body 1 is provided with a fixed rod 3; the bracket fitting 2 includes a horizontally arranged movable rod 4 and a vertically arranged movable rod 5; the horizontally arranged movable rod 4 is arranged on the fixed rod 3, and the horizontally arranged movable rod 4 can slide and adjust along the axial direction of the fixed rod 3; the vertically arranged movable rod 5 is arranged on the horizontally arranged movable rod 4, and the vertically arranged movable rod 5 can slide and adjust along the axial direction of the horizontally arranged movable rod 4; and, the fixed rod 3, the horizontally arranged movable rod 4 and the vertically arranged movable rod 5 are perpendicular to each other in pairs, and the vertically arranged movable rod 5 is configured to carry the measuring end 6 of the thermocouple.

[0028] Based on the above technical solution, when measuring the effective furnace temperature uniformity of a heat treatment furnace, this measuring frame can be placed inside the heat treatment furnace. The measuring end 6 of the thermocouple is arranged on the vertically arranged movable rod 5, and the measuring end 6 of the thermocouple can measure the temperature at its location. Then, by changing the measuring position of the measuring end 6 of the thermocouple, the horizontally arranged movable rod 4 can be slid axially relative to the fixed rod 3 and along the axial direction of the fixed rod 3. Correspondingly, the measuring end 6 of the thermocouple will follow the horizontally arranged movable rod 4 to slide. Next, the vertically arranged movable rod 5 can be slid axially relative to the horizontally arranged movable rod 4 and along the axial direction of the horizontally arranged movable rod 4. Correspondingly, the measuring end 6 of the thermocouple will follow the vertically arranged movable rod 5 to slide. Then, use a tool to measure the position where the measuring end 6 of the thermocouple will measure next, and disassemble the measuring end 6 of the thermocouple from the vertically arranged movable rod 5 and arrange it at this position. The fixed rod 3, the horizontally arranged movable rod 4, and the vertically arranged movable rod 5 are perpendicular to each other in pairs. In this way, the measuring end 6 of the thermocouple can accurately measure the temperature at this position. Therefore, this temperature measuring frame can assist the measuring end 6 of the thermocouple, and the measuring end 6 of the thermocouple can be set at any position inside the temperature measuring frame, and this can accurately measure the uniformity of the effective furnace temperature in the heat treatment furnace.

[0029] This temperature measuring frame assists the measuring end 6 of the thermocouple to perform positioning measurements on all temperature points in the effective temperature range, without the need to extend the measuring end 6 of the thermocouple from a fixed point. In this way, in a high-temperature environment, the measuring end 6 of the thermocouple will not be affected by its own gravity and other stresses, and the measuring position will not change. This can accurately measure the temperature in the effective temperature range of the heat treatment furnace and can accurately reflect the uniformity of the temperature in the effective temperature range.

[0030] It should also be noted that according to the standard of GJB 509B-2008 "Heat Treatment Process Quality Control", the temperature tolerance requirements for the effective working area of three types of heat treatment furnaces are within ±10°C, then it meets the heat treatment requirements of parts.

[0031] In addition, inside the body 1, the fixed rod 3, the horizontally arranged movable rod 4, and the vertically arranged movable rod 5 are perpendicular to each other in pairs, and the horizontally arranged movable rod 4 can be slid axially and adjusted along the axial direction of the fixed rod 3, and the vertically arranged movable rod 5 can be slid axially and adjusted along the axial direction of the horizontally arranged movable rod 4. The measuring end 6 of the thermocouple can be mounted on the vertically arranged movable rod 5. Then, the measuring end 6 of the thermocouple can be arranged at any position inside the body 1. When the measuring frame is placed inside the heat treatment furnace, correspondingly, the measuring end 6 of the thermocouple can be arranged at any position in the effective temperature range inside the heat treatment furnace, that is, it can accurately measure the uniformity of the effective temperature range of the heat treatment furnace.

[0032] To facilitate the operation of workers, the measuring end 6 of the thermocouple is arranged at a specified position. A first scale 7 is provided on the fixed rod 3 along its axial direction, a second scale 8 is provided on the horizontally arranged movable rod 4 along its axial direction, and a third scale 9 is provided on the vertically arranged movable rod 5 along its axial direction.

[0033] Workers can, according to the actual measurement requirements, accurately slide the horizontally arranged movable rod 4 relative to the fixed rod 3 through the first scale 7. At this time, the vertically arranged movable rod 5 and the thermocouple measuring end 6 thereon also move accordingly. Then, through the second scale 8, the vertically arranged movable rod 5 is slid relative to the horizontally arranged movable rod 4. At this time, the thermocouple measuring end 6 moves along with the vertically arranged movable rod 5. After that, the worker can disassemble the thermocouple measuring end 6 from the vertically arranged movable rod 5 and, through the third scale 9, accurately arrange the thermocouple measuring end 6 at the position where measurement is required next. The scales provided on the fixed rod 3, the horizontally arranged movable rod 4, and the vertically arranged movable rod 5 can eliminate the need for workers to hold measuring tools, facilitate the operation of workers, improve the measurement efficiency, and reduce the burden on workers.

[0034] The horizontally arranged movable rod 4 can be slidably adjusted relative to the fixed rod 3. However, after the horizontally arranged movable rod 4 slides to a specified position relative to the fixed rod 3, the horizontally arranged movable rod 4 needs to be fixed. Similarly, the vertically arranged movable rod 5 can be slidably adjusted relative to the horizontally arranged movable rod 4. However, after the vertically arranged movable rod 5 slides to a specified position relative to the horizontally arranged movable rod 4, the vertically arranged movable rod 5 needs to be fixed to prevent the horizontally arranged movable rod 4 and the vertically arranged movable rod 5 from shifting due to heat in a high-temperature environment.

[0035] Therefore, in some embodiments, a first connection groove 10 is provided at the end of the horizontally arranged movable rod 4, and the fixed rod 3 is detachably connected to the inside of the first connection groove 10. A second connection groove 11 is provided at the end of the vertically arranged movable rod 5, and the horizontally arranged movable rod 4 is detachably connected to the inside of the second connection groove 11.

[0036] When it is necessary to move the horizontally arranged movable rod 4, the horizontally arranged movable rod 4 can be released relative to the fixed rod 3 and moved. After the movement is completed, the horizontally arranged movable rod 4 is locked to the fixed rod 3. Similarly, when it is necessary to move the vertically arranged movable rod 5, the vertically arranged movable rod 5 can be released relative to the horizontally arranged movable rod 4 and moved. After the movement is completed, the vertically arranged movable rod 5 is locked to the horizontally arranged movable rod 4.

[0037] And to ensure the stable connection between the horizontally disposed movable rod 4 and the fixed rod 3, in the present utility model, the body 1 has a support rod 12 parallel to the fixed rod 3. Both ends of the horizontally disposed movable rod 4 are provided with first connection grooves 10, and the fixed rod 3 and the support rod 12 are respectively connected to the inside of the two first connection grooves 10, and both the fixed rod 3 and the support rod 12 are detachably connected to the horizontally disposed movable rod 4 through locking members.

[0038] Also, to ensure the stable connection between the vertically disposed movable rod 5 and the horizontally disposed movable rod 4, in the present utility model, the bracket fitting 2 includes two horizontally disposed movable rods 4 which are arranged in parallel. Both ends of the vertically disposed movable rod 5 are respectively detachably connected to the two horizontally disposed movable rods 4, and the vertically disposed movable rod 5 can be stably arranged between the two horizontally disposed movable rods 4 without deviation, which can ensure the accurate position of the measuring end 6 of the thermocouple without deviation.

[0039] And, one end of the vertically disposed movable rod 5 far from the second connection groove 11 is further provided with a through hole 13, and one of the horizontally disposed movable rods 4 passes through the inside of the through hole 13.

[0040] In actual measurement, multi-point temperature measurement needs to be carried out simultaneously. Therefore, the temperature measuring frame includes a plurality of bracket fittings 2 which are spaced apart and arranged inside the body 1.

[0041] In this way, multi-point measurement can be carried out simultaneously within the effective temperature range, which can accelerate the measurement progress, save measurement time, and can also be used for measuring to reduce the size of the effective temperature range when the existing temperature difference requirements are not met in the effective temperature range, saving the cost and time of remanufacturing the temperature measuring frame.

[0042] During measurement, the measurement frame needs to be placed inside the heat treatment furnace, and the inside of the heat treatment furnace is heated. To ensure that the temperature in the measurement area inside the measurement frame can be accurately heated and the heat will not be blocked by the body 1 but can be completely transmitted, it is required that the body 1 is a frame structure with a hollow exterior.

[0043] In some embodiments, the body 1 is a cubic frame assembled by multiple rods, and one of the rods is configured as the fixed rod 3. And the material of the body 1 should be the same as that of the horizontally disposed movable rod 4 and the vertically disposed movable rod 5, and a steel material with good heat resistance can be selected.

[0044] Select a square steel material with scales to weld the cubic frame body 1, select a quick-disassembly square steel with scales as the horizontally disposed movable rod 4 and the vertically disposed movable rod 5, process a hollow fork shape as the connection groove to fit the size of the body 1, fix it on the body 1 with bolts, tie and fix the measuring end 6 of the detection thermocouple on the vertically disposed movable rod 5 for temperature measurement.

[0045] The technical means disclosed by the solution of the present utility model are not limited to those disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
