Description

Technical Field

[0001] This utility model relates to the field of clamp structures, specifically to a temperature measuring clamp for a light source. Background Technology

[0002] A certain type of light source relies on a live wire mounted inside an arc-shaped housing to emit light. If the temperature is too high after the light source emits light, it can damage the performance of adjacent components mounted at the rear and outer edges of the light source. Besides calculating the light energy generated by the live wire during the design phase, random checks are required after manufacturing and before assembly. A temperature measurement test is also necessary; that is, after the live wire emits light, the temperature at the rear and outer edges of the light source must be below a certain safe temperature to ensure the safety of adjacent components. To solve these problems, this utility model discloses a temperature measuring fixture and operating method for light source temperature testing. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] like Figures 1 to 7 As shown, the temperature measuring fixture for the light source in this embodiment includes: a body 2 with a mounting position for accommodating the light source product 12; a heat insulation plate disposed on the mounting position; a positioning shaft 9 threaded onto the body 2; and a pressure block 8 mounted on the positioning shaft 9 via a double-ended stud 7. The pressure block 8 is moved by a handle nut 10, causing it to press against the light source product 12. One end of the double-ended stud 7 is screwed into the central threaded hole of the positioning shaft 9 and locked in place by a first adjusting nut 11. The double-ended stud needs to undergo heat treatment to improve its mechanical strength, while ensuring that the machining precision of its threaded portion reaches a high standard to support multiple loading and unloading requirements.

[0035] The heat insulation panel includes at least a first heat insulation panel 4 disposed on the bottom surface of the mounting position, a second heat insulation panel 3 disposed on the side surface of the mounting position, and a third heat insulation panel 5 disposed on the outside of the positioning shaft 9. The heat insulation requirements of the heat insulation panel are to prevent heat conduction from affecting the overall accuracy during temperature measurement and to protect the equipment from damage due to excessively high temperatures. From a technical perspective, a stable and firm bonding effect can be achieved by selecting asbestos materials with high heat resistance and low thermal conductivity, supplemented by environmentally friendly adhesives. The heat insulation panel uses high-temperature resistant heat insulation materials (such as asbestos, ceramic fiber, aerogel, etc.), and is not limited to asbestos materials.

[0036] The first heat insulation board 4, the second heat insulation board 3, and the third heat insulation board 5 are installed by adhesive bonding.

[0037] A locking screw 6 is provided between the body 2 and the positioning shaft 9. The locking screw 6 is a key component for auxiliary positioning and fixing the positioning shaft 9. Its main function is to lock the positioning shaft in its preset working position when tightened. By precisely installing the locking screw into the pre-machined screw hole and applying appropriate force, it presses against the surface of the positioning shaft to form a lock.

[0038] The main body 2 has six clamping threaded holes, and clamping screws 1 are installed in the clamping threaded holes. The clamping screws 1 cooperate with the clamping threaded holes and gradually approach the rear part or outer circular side wall of the light source during rotation, applying a certain clamping force to complete the fixing task. The threaded end of the clamping screw 1 is machined flat to avoid damaging the product.

[0039] The light source product 12 includes a fire tube 121, and a carbon felt insulation layer 122 is provided at the bottom of the fire tube 121.

[0040] The bottom of the main body 2 is provided with a clamping part 21, which is adapted to a universal pliers to achieve clamping and fixing.

[0041] The operation method of the temperature measuring fixture for the light source in this embodiment includes the following steps:

[0042] S1. One end of the positioning shaft 9 is threaded into the center threaded hole of the body 2. After it is screwed into place, it is tightened with the stop screw 6.

[0043] S2. The third heat insulation plate 5 is glued to the circumference of the positioning shaft 9 with strong adhesive, and the first heat insulation plate 4 and the second heat insulation plate 3 are glued to the inside of the body 2 with strong adhesive.

[0044] S3. Screw one end of the double-ended stud 7 into the center threaded hole of the positioning shaft 9 and tighten it with a nut;

[0045] S4. When conducting the temperature measurement test, after the light source product 12 is installed in the body 2 and pressed down by the pressure block 8, the handle nut 10 is initially tightened. Then, the clamping screw 1 is screwed into the threaded holes at the rear and circumferential sides of the body 2 respectively to press the rear wall and outer circumferential side wall of the light source product 12. Finally, the handle nut 10 is tightened.

[0046] S5. Clamp the clamping part 21 onto the universal vise on the workbench. After the operator maintains a safe distance, remotely control the electronic detonator to detonate the ignition tube. After all the ignition tubes have detonated and emitted light, use a temperature gun to measure the temperature of the rear wall and outer side wall of the light source. If it is lower than the set safe temperature, the product is qualified.

[0047] Within the scope of the technology disclosed in this utility model, any variations or substitutions that can be easily conceived should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
