Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts painting device. Background Art

[0002] The paint spraying of automobile parts is generally baking paint. In the car factory, after the welding of the frame and the shell is completed (sometimes manual repairs are performed), the next process is painting. Generally speaking, the first step is primer. The bare shell is immersed in the paint tank, the dried primer is taken out, and then sent to the dust-free workshop, the topcoat is sprayed with an electrostatic spraying process, and then it is sent to the drying room for drying.

[0003] In the prior art, when some small parts of a car are sprayed with paint, these small parts are usually hung on a rack, and then workers hold a paint spray gun to spray them. However, when using this method to spray parts, usually only one side of the part can be sprayed with paint. After the single-sided painting is completed, the part needs to be manually turned over and sprayed again. There are certain defects in the spraying efficiency. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] See also Figure 1-3A paint spraying device for automobile parts comprises a base 1 and a tank body 2 mounted on the base 1, a hatch (not shown) being mounted on the tank body 2, a lifting seat 3 being movably mounted in the tank body 2 through a lifting mechanism, and a plurality of rotating shafts 4 being rotatably arranged around the lifting seat 3 in the tank body 2, a plurality of suspension frames 5 being mounted on the rotating shaft 4, a plurality of spray heads 6 being mounted on the side of the lifting seat 3 corresponding to the direction of the rotating shaft 4, the spray heads 6 being connected to a liquid supply mechanism 8 arranged on the tank body 2 through a corrugated hose 7, a driving mechanism for driving the plurality of rotating shafts 4 to rotate synchronously being further arranged in the tank body 2, by arranging the lifting seat 3, the lifting mechanism, the rotating shaft 4 and the driving mechanism, the lifting mechanism can drive the plurality of rotating shafts 4 to rotate 90° and stop rotating in the process of driving the lifting seat 3 to move up and down, in this process, a plurality of parts suspended on the suspension frame 5 can realize the switching of the paint spraying surface, and the spraying and flipping and re-spraying of a plurality of parts can be realized by cooperating with the up and down operation of the spray head 6, thereby eliminating the manual operation steps of flipping the parts, and improving the painting efficiency of the parts.

[0018] Among them, the lifting mechanism includes a reciprocating screw 9 rotatably arranged in the tank body 2 and a plurality of guide rods 10 fixedly installed around the reciprocating screw 9, the reciprocating screw 9 is driven by a motor arranged in the base 1, and a reciprocating moving part 11 adapted thereto is installed on the reciprocating screw 9, and the reciprocating moving part 11 is fixedly embedded in the lifting seat 3, and a sliding sleeve 12 is movably installed on the guide rod 10, and the sliding sleeve 12 is fixedly installed on the side of the lifting seat 3. Specifically, when the reciprocating screw 9 drives the lifting seat 3 to move up and down, when the spraying range of the paint head 6 leaves the component, the paint head 6 stops the spraying operation. At this time, the driving mechanism drives the rotating shaft 4 to start rotating 90° to realize the flipping of the component. When the lifting seat 3 continues to operate upward, the paint head 6 can spray paint on the flipped component.

[0019] Preferably, the driving mechanism includes a first gear 13, a transmission shaft 14, a second gear 15, a half gear 16 and a third gear 17. The first gear 13 is rotatably set in the base 1 and is coaxially fixedly connected to the reciprocating screw 9. The periphery of the first gear 13 is meshed with second gears 15 with the same number as the rotating shaft 4. The transmission shaft 14 is rotatably set, and a half gear 16 is also fixedly mounted on the transmission shaft 14. The third gear 17 is meshed with the half gear 16, and the third gear 17 is coaxially fixedly mounted on the rotating shaft 4. The setting of the driving mechanism does not require the additional setting of a driving element for driving multiple rotating shafts 4 to rotate, thereby reducing the production cost of the device.

[0020] The diameter of the first gear 13 is smaller than the diameter of the second gear 15 .

[0021] Specifically, when the reciprocating screw 9 is driven to rotate, the lifting seat 3 moves up and down with the reciprocating moving part 11. Under the meshing transmission of the first gear 13 and the second gear 15, the half gear 16 on the transmission shaft 14 rotates therewith. When the teeth on the half gear 16 mesh with the teeth of the third gear 17, the rotating shaft 4 can be driven to rotate 90° and stop rotating, thereby realizing the turning over of multiple parts on the rotating shaft 4. In conjunction with the up and down reciprocating movement of the lifting seat 3, the comprehensive painting of the parts can be realized.
