Description

Technical Field

[0001] The utility model relates to the field of surface treatment, in particular to a piston phosphating device. Background Art

[0002] In the field of piston phosphating, the traditional method of piston phosphating hanging relies on the inner top bracket to support the piston during phosphating. However, this method has many drawbacks, especially when processing pistons of different models and different inner cavity depths.

[0003] First, due to the diversity of piston models, traditional inner top brackets are difficult to perfectly adapt to all piston models, resulting in color variations in the phosphating positioning points. Second, the varying depths of the piston cavity also make gas accumulation an inevitable problem during the phosphating process. This accumulation of gas causes phosphating color variations, seriously affecting the phosphating quality of the piston. Furthermore, traditional mounting methods can also cause color variations in the mounting surface, further reducing the overall effectiveness of the piston phosphating.

[0004] In summary, the traditional piston phosphating mounting method has defects such as color difference of phosphating positioning points, color difference of gas accumulation in the inner cavity and color difference of the hanger contact surface under the conditions of diverse piston models and different inner cavity depths, and cannot meet the high quality requirements of piston phosphating treatment.

[0011] Furthermore, an anti-rotation stainless steel bar is provided on the mounting plate, and the anti-rotation stainless steel bar is supported on the side of the arc-shaped structure of the base to prevent the positioning tool from rotating along the axis of the fixing bolt.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0021] like Figure 1-2As shown, a piston phosphating equipment includes a positioning tool and a material rack. Multiple positioning tools are fixed to the material rack by bolts. A mounting plate is provided on the material rack. The mounting plate is fixed to the material rack at a certain angle to the horizontal plane. Mounting holes are provided on the mounting plate. Connecting holes are provided on the positioning tool. The positioning tool is fixed to the mounting plate by inserting fixing bolts into the connecting holes and the mounting holes. An anti-rotation stainless steel bar is also provided on the mounting plate, and the anti-rotation stainless steel bar is welded to the mounting plate.

[0022] The positioning fixture comprises a chuck plate 1 and a base 2. These two structures are coaxial, arc-shaped, with their specific shape and dimensions determined by the piston to be mounted. The chuck plate 1 is integrally connected to the inside of the base 2, its shape matching the piston's cast iron ring groove. The chuck plate 1 is used to position the piston.
