Rotary hanging tool suitable for piston phosphorization

Abstract

The invention particularly discloses a rotary hanging tool for piston phosphorization. The rotary hanging tool comprises a fixed bracket, wherein a drum box body is arranged in the fixed bracket; two rows of special tools are arranged in the drum box body in a longitudinal symmetry manner, and each row comprises multiple sets of special tools; a transmission device is arranged on one side of the fixed bracket; the lower trays of the two rows of special tools are symmetrically mounted on a tray bracket, the upper trays of the upper row of special tools are fixed at the top of the drum box body and correspond to the lower trays of the upper row of special tools, and the upper trays of the lower row of special tools are fixed at the bottom of the drum box body and correspond to the lower trays of the lower row of special tools. Due to the adoption of the structure, the rotary hanging tool has the benefits that phosphorization liquid comprehensively and fully makes contact with a piston and the best phosphorization effect is achieved.

Description

[0001] technical field [0002] The invention relates to a rotary hanger suitable for piston phosphating. Background technique [0003] With the rapid development of the automobile industry, it is a rare opportunity for engine piston manufacturers. At the same time, quality has become a prominent issue, and it is the key point for the competition of various OEMs and the evaluation of suppliers. However, the processes from materials, casting, machining to heat treatment have been mature. Therefore, to improve quality, the only way to improve equipment performance is to improve equipment performance. At present, hooks are generally used for piston phosphating equipment hangers (such as figure 1 As shown), in this way, because the piston is in a static state during phosphating, the inner cavity will hold air, resulting in poor phosphating effect. Some manufacturers also add air blowing water devices on this basis to make the liquid produce bubbling effects, but due to phosphat...

At the same time, quality has become a prominent issue, and it is the key point for the competition of various OEMs and the evaluation of suppliers. However, the processes from materials, casting, machining to heat treatment have been mature. Therefore, to improve quality, we can only improve equipment performance

At present, hooks are generally used for piston phosphating equipment hangers (such as figure 1 As shown), in this way, because the piston is in a static state during phosphating, the inner cavity will hold air, resulting in poor phosphating effect. Some manufacturers also add air blowing water devices on this basis to make the liquid produce bubbling effects, but due to phosphating The tank is generally filled with more than 1.5 tons of water, and the air blowing water device is difficult to achieve a large agitation of the liquid, and the effect is not very good, especially where the hook is in contact with the piston, there is no phosphating at all, which seriously affects the quality of phosphating. cause the piston to rust
