Description

Technical Field

[0001] This utility model relates to the field of piston manufacturing technology, and in particular to a piston phosphating device. Background Technology

[0002] As engines increasingly demand lower fuel consumption, lower noise, and lower congestion, ensuring piston quality and improving production efficiency have become key concerns for domestic piston manufacturers.

[0003] Currently, there is no mature, dedicated automated phosphating equipment for pistons in China. Most piston manufacturers still use manual phosphating, which is not only physically demanding for workers but also poses a serious health risk due to the toxicity and corrosiveness of the phosphating solution. Some manufacturers use a cantilever structure, where the piston is mounted on a hook in a material frame and a cylinder is used to lift and move the piston and material frame. This structure has limited load-bearing capacity, restricting the number of pistons that can be phosphated at one time, resulting in low efficiency. Furthermore, the piston is stationary during operation, causing air to trap inside the piston cavity, leading to poor phosphating results. Some manufacturers add a water-blowing air device to agitate the liquid, but due to the large liquid volume, the flow within the tank is not very good. Additionally, the area where the hook contacts the piston is not phosphated, severely affecting the quality of phosphating and causing the piston to rust.

[0004] Some piston manufacturers use piston phosphating equipment that is an improvement on general-purpose component phosphating equipment. The trolley uses a gantry structure without any protection, posing a safety hazard when people come into close contact with the moving trolley. It also lacks a phosphating solution filtration device, which severely affects the piston phosphating quality over prolonged use. Although this equipment is equipped with a rotating material frame, it does not use the dedicated rotating hanger employed in this invention. The piston is prone to collisions within the material frame, and air can trap inside the piston cavity. Blind spots that cannot be phosphated will also appear on the piston top surface and stop, resulting in compromised piston phosphating quality. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a piston phosphating device that can realize the placement of multiple pistons and perform phosphating on the pistons.

[0006] This utility model is implemented using the following method: a piston phosphating device, including a phosphating chamber, a phosphating pool with an open upper surface is provided at the right end of the bottom surface of the phosphating chamber, openings are provided at the upper ends of both the left and right sides of the phosphating chamber, support blocks are provided at both ends of the upper surface of the phosphating chamber, annular guide rails are provided on the support blocks, the annular guide rails are provided through the openings, multiple overhead cranes are provided at equal intervals on the annular guide rails, a placement component for placing the piston is provided on the lower surface of the overhead cranes, multiple stirring blades are provided at equal intervals on the bottom surface of the phosphating pool, a protective net cover is provided on the stirring blades, and a water pump is provided at the right end of the bottom surface of the phosphating pool, the water pump is connected to a water pumping pipe.

[0007] Furthermore, the placement component includes a telescopic cylinder, which is provided on the lower surface of the crane. A lifting block is provided at the end of the telescopic rod of the telescopic cylinder. A support rod is provided on the lower surface of the lifting block.

[0008] Furthermore, a collection hopper is provided at the left end of the bottom surface of the phosphating chamber, and the collection hopper is connected to a drain pipe.

[0009] The beneficial effects of this utility model are as follows: This utility model incorporates a placement component, stirring blades, and a phosphating tank into the device, enabling the placement and fixation of multiple pistons. Furthermore, the stirring blades accelerate the flow rate of the phosphating solution within the phosphating tank, thus better achieving the phosphating effect on the piston surface.

Automated production significantly improves production efficiency and reduces the labor intensity of workers. The phosphating solution can be recycled, reducing operating costs. The placement component not only solves the problem of air trapped inside the piston cavity but also ensures full contact between the piston and the liquid, maximizing the phosphating effect.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Please see Figure 1 and Figure 2As shown, this utility model provides an embodiment: a piston phosphating device, including a phosphating chamber 1, a phosphating pool 2 with an open upper surface at the right end of the bottom surface of the phosphating chamber 1, openings 11 at the upper ends of both the left and right sides of the phosphating chamber 1, support blocks 12 at both ends of the upper surface of the phosphating chamber 1, annular guide rails 13 on the support blocks 12, the annular guide rails 13 passing through the openings 11, multiple overhead cranes 14 at equal intervals on the annular guide rails 13, a placement piece 3 for placing the piston on the lower surface of the overhead cranes 14, multiple stirring blades 4 at equal intervals on the bottom surface of the phosphating pool 2, a protective net cover 41 on the stirring blades 4, and a water pump 21 at the right end of the bottom surface of the phosphating pool 2, the water pump 21 being connected to a water pumping pipe 22. This allows multiple pistons to be placed in the placement piece 3 and then transported on the annular guide rail 13 by the overhead crane 14. Through the action of the stirring blades 4, the flow rate of the phosphating liquid in the phosphating tank can be accelerated, thereby better achieving the phosphating effect on the piston surface.

Multiple partition blocks 37 are disposed at equal intervals between the support ring 36 and the annular mesh 35. This allows the lifting block 32 to be lifted and lowered by the telescopic cylinder 31, thereby placing the grid plate 34 into the phosphating tank 2. Then, through the action of the partition blocks 37, multiple pistons can be placed without contacting each other, facilitating the phosphating operation.
