Description

Technical Field

[0001] The present invention relates to the field of fixture structures, and particularly to a temperature measuring fixture and an operation method for a light source. Background Art

[0002] A certain light source relies on a firing tube assembled in an arc-shaped housing to emit light by explosion. After the product emits light, if the temperature is too high, it will damage the performance of adjacent components assembled at the rear and outer circular side of the light source. In addition to calculating the light energy generated by the firing tube in the light source during design, sampling inspection is required before assembly after the light source is manufactured, and temperature measurement tests are also required. That is, after the firing tube emits light by explosion, the temperature at the rear and outer circular side of the light source must be less than a certain safety temperature to ensure the safety of the performance of adjacent components. To solve these problems, a temperature measuring fixture and an operation method for a light source have been invented for the temperature measurement test of the light source. Summary of the Invention

[0003] The purpose of the present invention is to provide a temperature measuring fixture for a light source to solve the problems that the existing light source cannot effectively measure temperature and has low safety performance.

One end of the double-headed stud 7 is screwed into the central threaded hole of the positioning shaft 9 and locked and fixed by a first adjusting nut 11. This double-headed stud needs to be heat-treated to improve its mechanical strength, and at the same time ensure that the machining fineness of its threaded part reaches a high standard to support multiple loading and unloading requirements.

The adiabatic requirement of the heat insulation plate is to avoid the influence of heat conduction on the overall accuracy when measuring temperature and to protect the equipment from damage caused by excessive temperature. From a technical perspective, it can be achieved by selecting asbestos materials with high heat resistance and low thermal conductivity, supplemented by environmentally friendly adhesives to achieve a stable and firm pasting effect. The heat insulation plate is a high-temperature heat insulation material (such as asbestos, ceramic fiber, aerogel, etc.), not only using asbestos materials.

[0044] Six pressing threaded holes are provided on the main body 2, and pressing screws 1 are provided in the pressing threaded holes. The pressing screws 1 cooperate with the pressing threaded holes and gradually approach the rear part or the outer circular side wall of the light source during rotation and apply a certain pressing force to it to complete the fixing task. The threaded end of the pressing screw 1 is flattened to avoid damaging the product.

[0046] A clamping part 21 is provided at the bottom of the main body 2, and the clamping part 21 is adapted to a universal vise to achieve clamping and fixing.

[0047] The operation method of the temperature measurement fixture for the light source of this embodiment includes the following steps:

[0048] S1. One end of the positioning shaft 9 is screwed into the central threaded hole of the body 2. After screwing in place, tighten it with the set screw 6.

[0049] S2. Paste the third heat insulation plate 5 on the circumference of the positioning shaft 9 with strong glue, and paste the first heat insulation plate 4 and the second heat insulation plate 3 inside the body 2 with strong glue.

[0050] S3. Screw one end of the stud 7 into the central threaded hole of the positioning shaft 9 and lock it with a nut.

[0051] S4. When conducting the temperature measurement test, install the light source product 12 into the body 2, press it with the pressure block 8, and then initially screw on the handle nut 10. Then, screw the compression screws 1 into the threaded holes at the rear and circumferential side of the body 2 respectively to compress the rear wall and the outer circumferential side wall of the light source product 12. Finally, tighten the handle nut 10.

[0052] S5. Clamp the clamping part 21 on the universal vise of the workbench. After the operator keeps a safe distance, remotely control the electronic detonator to detonate the fuse tube. After all the fuse tubes have detonated and emitted light, use a temperature measuring gun to measure the temperature of the rear wall and the outer circumferential side wall of the light source. If it is lower than the set safety temperature, the product is qualified.
