Die-cast lamp shell leak detection clamping tool

Abstract

The invention discloses a die-cast lamp shell leak detection clamping tool. The die-cast lamp shell leak detection clamping tool is used for clamping a die-cast lamp shell. The die-cast lamp shell leak detection clamping tool comprises a work-piece table, a sealing ring, a fast clamping table arranged on the work-piece table, and a fast clamping device; the work-piece table is provided with an annular groove; the sealing ring is arranged in the annular groove; the fast clamping table is arranged at one side of the sealing ring; and the fast clamping device is installed on the fast clamping table and is used for pressing the die-cast lamp shell on the sealing ring so as to seal the inner cavity of the die-cast lamp shell. According to the die-cast lamp shell leak detection clamping tool of the invention adopted, the sealing ring is installed on the work-piece table, the die-cast lamp shell is pressed onto the sealing ring through the fast clamping device, so that the sealing of the inner cavity of the die-cast lamp shell can be realized; and since a sealing ring is not required to be installed on the die-cast lamp shell, when leak detection is carried out on a plurality of die-cast lamp shells, a plurality of times of dissembling and assembling sealing rings can be avoided, namely, labor can be saved, and the sealing ring has little possibility of being damaged.

Description

Technical field [0001] The invention relates to the technical field of LED lamps, in particular to a leak detection and clamping tool for a die-cast lamp shell. Background technique [0002] LED lamp (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is an electric light source without filament, which directly converts electrical energy into light energy. [0003] LED lamps have the characteristics of energy saving and long life, avoiding the trouble of often needing to replace bulbs, and are favored by more and more users. However, the heat dissipation problem of LED lamps is also a key issue, and the heat dissipation problem seriously affects the light efficiency and lifespan of the LED light source. In order to improve the heat dissipation effect of the LED lamp, some factories make the lamp housing of the LED lamp by metal die-casting, and set a number of heat sinks on the outer surface of the lamp hous...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 as shown, figure 1 It is a structural schematic diagram of an existing die-casting lamp housing with heat dissipation function for LED lamps. The die-casting lamp housing 100 has an open inner cavity. After the die-casting lamp housing 100 is manufactured, the die-casting lamp housing needs to be sealed 100, and then detect whether the die-casting lamp housing 100 is leaking; the general method is to set the air-filling hole 101 connected to the inner cavity of the die-casting housing 100 on the die-casting lamp housing 100, and the die-casting lamp housing 100 corresponding to its A sealing groove is set on the bottom surface of the opening; when testing, a sealing ring is first placed in the sealing groove, and then the panel is manually fixed on the die-casting lamp housing 100 with the sealing ring by screws, and then the air filling hole 101 is connected to the air supply device. Finally, put the sealed die-casting lamp housing 100 into the water together with the air supply pipe. The air supply device sends air into the die-casting lamp housing 100 through the air supply pipe. Observe whether there are bubbles in the water. If there are no air bubbles in the die-casting lamp housing 100 If the airtightness is good, otherwise, it proves that the airtightness of the die-casting lamp housing 100 is not good

This measurement method has low working efficiency and requires frequent disassembly and assembly of the sealing ring, which is time-consuming and laborious, and is also easy to damage the sealing ring
