Handheld paint spraying device for production of electric vehicles

Abstract

The invention discloses a handheld paint spraying device for production of electric vehicles. The handheld paint spraying device for the production of the electric vehicles comprises a spray gun bodyand a handle, wherein a feed pipe is connected with the bottom of the spray gun body through a bolt, a conveying pipe is connected with the left side of the top of the spray gun body through a flange,a protection tube is arranged on the outer side of the conveying pipe, baffles are arranged on the front side of the rear side of the interior of the conveying pipe, a fixing plate and a dummy plateare arranged on the inner side of each baffle, lead screws are connected with the interiors of the fixing plates and the dummy plates, and a spray head is installed at one end, far away from the spraygun body, of the conveying pipe. According to the handheld paint spraying device for the production of the electric vehicles, the lead screws are arranged, the lead screws and the dummy plates are connected in a threaded mode, the dummy plates are correspondingly connected with the fixing plates in a sliding mode, and meanwhile threads of the upper end and the lower end of each lead screw are different in screwing direction, and accordingly the two dummy plates are driven to simultaneously mode when the lead screws rotate, flow rate of paint is adjusted, the purpose of changing the spraying amount is realized, and the handheld paint spraying device for the production of the electric vehicles is enabled to apply to a large quantity of demands.

Description

technical field [0001] The invention relates to the technical field of electric vehicle production, in particular to a hand-held painting device for electric vehicle production. Background technique [0002] Electric vehicles are powered by vehicle-mounted power supplies and driven by motors to drive wheels. Compared with fuel vehicles, they can reduce environmental pollution. During the production process of electric vehicles, the surface of the vehicle needs to be painted. The same type of vehicle can There are different paint colors. In order to facilitate the work of the staff, a hand-held paint spraying device is generally used. [0003] However, the existing hand-held paint spraying device still has some shortcomings during use, such as inconvenient adjustment of the spraying amount, the traditional way is to adjust at the feeding place, which is cumbersome, resulting in the spraying device not being applicable to more In addition, it is not convenient to protect the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hand-held electric vehicle production spraying device, to solve the inconvenient adjustment of the spraying amount of the spraying device on the market proposed by the above-mentioned background technology, the traditional way is to adjust at the feeding place, compared It is troublesome, which makes the spraying device not suitable for more needs, and it is not convenient to protect the nozzle when spraying paint, and it is easy to make the sprayed paint splatter, which affects the spraying effect of the car, thereby reducing the practicability of the spraying device.
