Abstract

The invention discloses an electric bicycle frame painting device. The electric bicycle frame painting device comprises a bottom plate. The bottom plate is provided with a side plate, the top of the side plate is provided with a top plate, the inside surface of the side plate is provided with a baffle plate and a painting chamber arranged on the baffle plate, a rotating plate is arranged in the painting chamber, a stepper motor is arranged below the top plate and connected to a drive shaft, the drive shaft penetrates through the painting chamber to be connected to the rotating plate, the bottom plate is provided with a painting unit connected to a spraying channel, the inner bottom of the painting chamber is provided with a spraying plate, a spraying cavity is arranged in the spraying plate and connected to the spraying channel, the top of the spraying plate is provided with a plurality of spraying holes arranged at equal intervals, the spraying holes are communicated with the spraying cavity in the spraying plate, and the spraying plate is arranged below the rotating plate. The electric bicycle frame painting device can spray paint to a frame easily, quickly, efficiently and evenly.

Description

technical field [0001] The invention relates to a painting device, in particular to an electric bicycle frame painting device. Background technique [0002] As the skeleton of the entire bicycle, the bicycle frame determines and affects the correctness and comfort of the riding posture to the greatest extent. Steel is the frame material that has been used for the longest time on bicycles. Its main advantages include good rigidity for long-time riding, elastic (shock-absorbing) pipes, many ways to join pipes and good processability, easy welding and no need for heat treatment, so the cost and The price is relatively low. The disadvantage is that it is too heavy, it is easy to rust if it is not properly maintained, it is not easy to shape the pipe, and there is a problem of metal fatigue. However, nowadays, many alloy steel materials can achieve good results in terms of rigidity, elastic coefficient, transmission, and stability. The only fly in the ointment is still the he...

Problems solved by technology

Titanium frame: The characteristics of titanium alloy are similar to the synthesis of aluminum alloy and carbon fiber. It has the elasticity similar to carbon fiber, but also has the lightness and rigidity of aluminum alloy, and it does not corrode and rust, and has a good riding feeling, but the disadvantage is that the material cost is expensive , because the refining and processing process of titanium is complicated and the welding technology is difficult, so the price remains high and cannot be universalized, and it is mostly used for small-diameter frames

The stock of titanium on the earth is the fourth among metals. Titanium and its alloys, the strength of castor alloy steel, but only half of its weight and strength, plus its superior corrosion resistance, have become necessary materials for military, aviation and space industries. At present, titanium alloy tubes are not widely used in bicycles, because of the high cost of smelting, difficult processing techniques such as welding, and complicated processing such as welding in a vacuum, so the price is high and it is difficult to be widely used.

The existing frame is inconvenient to spray metal paint, and the service life of the frame is short
