Pneumatic double-rod lifting device of automobile lamp airtightness detection device

Abstract

The invention discloses a pneumatic double-rod lifting device of an automobile lamp airtightness detection device. The pneumatic double-rod lifting device of the automobile lamp airtightness detection device comprises two sliding vertical rods which are arranged in a front-back mode, the lower ends of the two sliding vertical rods are all fixed onto a lower connecting plate, the connecting plate is arranged on a base plate of a first airtightness detection lifting mechanism, a sliding block which can slide vertically is sleeved outside each sliding vertical rod, the upper ends of the two sliding blocks are fixed onto the two ends of a cylinder connecting plate, the middle of the cylinder connecting plate and an upper piston rod of a two-stage cylinder are fixed, the lower end of the two-stage cylinder is fixed onto the lower connecting plate, and four surfaces of each sliding block are provided with convenient fixing grooves; the front surface of each pneumatic double-rod lifting devices is provided with a descending shock absorber. Therefore, the pneumatic double-rod lifting device of the automobile lamp airtightness detection device can detect the airtightness of an automobile lamp effectively and quickly, improves rate of finished products, reduces human costs and accordingly reduces production costs directly.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to a pneumatic double-rod lifting device of a car lamp air tightness testing machine. Background technique [0002] In modern industrial manufacturing, many complex machines are assembled manually, including mobile phones and computers in the electronics industry, as well as automobile manufacturing and other household appliances; these industrial manufacturing requires a lot of small assembly Links are combined together to complete, such as the production of lamp welding in automobile production, the lamp of the car is a part exposed to the outside of the car body, and will be covered by a large amount of water when it rains or when the car is washed, which has a certain impact on the airtightness of the lamp. Certain requirements, in the past production process, there is no such airtightness detection, only rely on manual control and visual inspection during production welding, ...

[0002] In modern industrial manufacturing, many complex machines are manually assembled, including mobile phones and computers in the electronics industry, as well as automobile manufacturing and other household appliances; these industrial manufacturing requires a lot of small assembly Links are combined together to complete, such as lamp welding production in automobile production, the lamp of the car is a part exposed to the outside of the car body, and will be covered by a large amount of water when it rains or when the car is washed, which has a certain impact on the airtightness of the lamp. Certain requirements. In the past production process, there was no such airtightness detection. Only rely on manual control and visual inspection during production welding. Such requirements cannot be met after the quality requirements are improved, and all unqualified products cannot be detected. products, leading to a decline in the overall yield rate, and at the same time testing one by one is also a waste of labor costs
