Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to a paint spraying processing equipment for treating the surface of a lifter. Background Art

[0002] The lifter is a hydraulic device on a tractor used to lift the plow. It is the most complex part of the tractor's hydraulic system. In principle, the lifter relies on the liquid pressure generated by the oil to achieve the lifting action.

[0003] The tractor hydraulic lifter structurally includes an outer lift arm and an inner lift arm connected together by a lift arm shaft, and a piston rod hinged on the inner lift arm, wherein the piston rod is connected to the piston of a hydraulic cylinder, and the hydraulic cylinder is installed in a sealed lifter housing, and the lifter housing contains hydraulic oil. A reversing valve is fixedly installed on one side of the lifter housing, and two oil outlets on the reversing valve are respectively connected to the lifting oil inlet and the lowering oil inlet on the hydraulic cylinder, and the lower part of the lifter housing is connected to the oil inlet of the hydraulic pump through a pipeline.

[0004] From the production process, the processing of the lift includes casting and forging, stamping, mechanical finishing, welding connection, surface spraying and assembly of various parts. Among them, surface spraying is a processing technology specifically for the lift shell. This is because the shell of the lift is directly exposed to the external environment during operation, so it is necessary to apply a layer of rust-proof and wear-resistant paint on its surface.

[0005] The shape of the lifter shell is a stamped square shell with one side open, which means that the lifter shell has five surfaces to be sprayed. In the process of spraying these five surfaces with existing spraying equipment, the following problems often occur:

[0006] 1. The inconvenience of multi-surface coating leads to low spraying efficiency. Specifically, the five outer surfaces of the lifter shell all need to be sprayed, but the existing equipment can only spray a single surface at a time, that is, the lifter shell needs to be disassembled and reassembled many times during the spraying process to adjust the spraying position, which is cumbersome and inefficient.

[0007] 2. Poor spraying effect and uneven paint distribution. Specifically, the shape of the lifter shell is a square shell with edges and corners. Unlike the surface spraying of cylindrical or cylindrical parts, the lifter shell cannot switch the spraying surface by driving the workpiece to rotate during spraying. This is because during the rotation reversing process, the undried paint sprayed on the outer surface of the lifter shell is easy to flow under the action of centrifugal force, which leads to uneven distribution of paint on the lifter shell.

[0008] 3. The selection of the clamping method and the clamping position is inconvenient. Specifically, due to the diversity of the spraying surface of the lifter housing, the setting of the clamping method and the selection of the clamping position cannot interfere with the feeding of the spraying mechanism during the spraying process.

[0009] 4. The drying range is limited and the drying is not comprehensive. Specifically, untimely drying will affect the spraying quality on the one hand, and on the other hand, it will also prolong the spraying time and increase the cost.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
