Vehicle lamp glass sand blasting test equipment and operation method

Abstract

The invention discloses vehicle lamp glass sand blasting test equipment and an operation method. The vehicle lamp glass sand blasting test equipment mainly comprises a box body, a sand blasting unit,a test unit, a transfer chamber and a funnel-shaped sand containing tank, wherein the sandblasting unit is fixed at the upper part of the box; the sand containing tank is fixed at the lower part of the box body; the test unit is located between the sand blasting unit and the sand containing tank. The test unit comprises first power, a first screw rod and a test bench; the sand blasting unit comprises a sand blasting mechanism and a switching mechanism; the sand blasting mechanism comprises a first spray gun, a second spray gun, second power, a second screw rod and a fixed table; a locking mechanism is arranged above the fixed table; the switching mechanism comprises a pull wire, a traction drive, a magnetic block and a guide groove; after sliding out of the fixing table, the sliding iron block of the first spray gun or the second spray gun enters a standby state; a magnetic block of the switching mechanism provides power support for lifting of the sliding iron block; the switching mechanism and the locking mechanism are used in cooperation to complete convenient switching of the first spray gun and the second spray gun, so that the situation that the test progress is affected due to blockage and damage of the spray guns in use is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical abrasion test of car lamp glass, in particular to a sandblasting test equipment and operation method of car lamp glass. Background technique [0002] Sand blasting equipment uses compressed air as power to form a high-speed jet beam to spray sand at high speed to the surface of the car light glass that needs to be studied, so that the company can have a better understanding of the impact resistance and corrosion resistance of the car light glass made of this material. Ok, I understand. [0003] The reference standard for the sandblasting test is: Appendix E "Mechanical Abrasion Test Method" of the GB 4599-2007 "Filament Bulb Headlamps for Automobiles" standard: [0004] GB4599-2007 [0005] Appendix E [0006] (Normative appendix) [0007] Mechanical wear test method [0008] E.1 Test equipment [0009] E.1.1 Spray gun [0010] The spray gun should be equipped with a nozzle with a diamet...

AI Technical Summary

Problems solved by technology

[0018] Existing sand blasting equipment usually uses a single spray gun. Once the spray gun is blocked or malfunctions, the test needs to be stopped immediately, and the test can only be continued after cleaning or replacing a new spray gun, which affects the progress of the test.
