[0001] The utility model relates to the technical field of processing push fork welded parts, in particular to a painting device for push fork welded parts. Background Technique

[0002] The hand pallet truck is a small-volume hydraulic device with simple operation and convenient use. The handle design conforms to the ergonomic principle and has three functions: lifting, carrying, and lowering. The integral casting oil cylinder has a beautiful appearance, is firm and durable, is made of high-quality steel plates, has a chrome-plated piston rod, and the internal overflow valve provides overload protection, effectively avoiding overloading and reducing maintenance costs. After the fork plate of the hand pallet truck is welded, it is necessary to spray paint the formed push fork welded parts.

[0003] The "fork automatic painting system" disclosed in its application number "201821167192.5" "includes a sealed painting chamber and a drying chamber. The top end surface of the top plate of the painting chamber is vertically fixed with support columns, and a bracket is slidably connected to the support columns. The bottom end of the bracket is connected to a double butterfly nozzle located inside the painting chamber; the bottom end surface of the top plate of the painting chamber is fixed with a track, and hangers for hanging the forks are equidistantly arranged on the track, and the hangers are driven by a motor to move uniformly along the track".

[0029] During use, first place the fork welding assembly of the hand pallet truck on the pallet 2, and place the brackets and forks of the fork welding assembly in the bracket slots 3 and the fork plate slots 4 respectively. Then, input paint into the nozzle 1205 through the input pipe 1204 and the riser pipe 1203 of the spraying assembly 12. The nozzle 1205 can simultaneously coat both sides of the fork with paint. After that, drive the horizontal lead screw 14 through the second motor 15. The horizontal lead screw 14 converts the rotational movement into the linear movement of one of the supports 8 through the second threaded sleeve 1301. The connecting rod 7 can maintain the synchronism of the two supports 8. The nozzle 1205 can spray paint on both sides along the direction of the fork of the fork welding assembly;

[0030] When the spray head 1205 moves to the bracket of the push fork welding part, the bidirectional lead screw 9 is driven by the first motor 10. The first thread sleeve 1201 can convert the rotational motion of the bidirectional lead screw 9 into the linear motion of the spray head 1205, so as to adjust the distance between the two spray heads 1205 on the same support 8, cover the surface of the bracket of the push fork welding part, and can spray paint on both sides of the bracket of the push fork welding part, ensuring the integrity of the spray paint between the forklift and the bracket, without the need for multiple spray painting treatments. During this process, the first support block 1202 and the second support block 1303 can support and guide the support 8 and the spray head 1205 respectively, enabling it to move smoothly and avoiding shaking and deviation.
