Description

Technical Field

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

[0002] Pistons operate under conditions of high temperature, high pressure, high speed, and poor lubrication. The piston reciprocates at a very high speed inside the cylinder, and the speed is constantly changing. This generates a large inertial force, subjecting the piston to a large additional load. Under these harsh conditions, the piston will deform and wear faster, and will also generate additional loads and thermal stress. At the same time, it will be subject to the chemical corrosion of the combustion gases. Therefore, the piston must have a lubrication function to extend its service life.

[0003] Currently, piston manufacturers generally use a whole-piece tin plating method to process pistons. However, the tin plating process is very complex, requiring multiple steps to complete. Each step requires different equipment to work together, which consumes a lot of human resources. Moreover, only a single piston can be tin-plated at a time, which is time-consuming, labor-intensive, costly, and results in low output. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a piston surface tin plating device that can realize tin plating operations on multiple piston surfaces.

[0005] This utility model is achieved by the following method: a piston surface tin plating device, including a support base, liquid storage tanks are provided at both the front and rear ends of the upper surface of the support base, drying tanks are provided at both the left and right ends of the upper surface of the support base, a support column is provided in the middle of the upper surface of the support base, a first motor is embedded in the upper surface of the support column, a first turntable is provided at the end of the output shaft of the first motor, rotating rods are connected around the first turntable, and a hanging part for hanging the piston is provided at the end of the rotating rod.

[0006] Furthermore, a first air outlet pipe is embedded in the bottom surface of the drying tank. The first air outlet pipe is connected to an air inlet pipe. Second air outlet pipes are connected to the left and right ends of the first air outlet pipe. The second air outlet pipes are perpendicular to the first air outlet pipes. Multiple air outlets are connected at equal intervals on the second air outlet pipes.

[0007] Furthermore, the mounting component includes a second motor, with the second motor embedded at the end of the rotating rod. A rotating block is provided at the end of the output shaft of the second motor, and a telescopic cylinder is provided on the lower surface of the rotating block. A second turntable is provided at the end of the telescopic rod of the telescopic cylinder. Multiple support rods are arranged in a ring around the center of the second turntable on the outer side of the second turntable. A third motor is provided on the upper surface of the end of the support rods, and a third turntable is provided at the end of the output shaft of the third motor. Multiple fixing rods are arranged in a ring around the center of the third turntable on the outer side of the third turntable. An arc-shaped limiting groove is formed on the upper surface of the fixing rod, and an opening and closing plate for opening and closing the arc-shaped limiting groove is hinged to the upper surface of the arc-shaped limiting groove.

[0008] The beneficial effects of this utility model are as follows: This utility model incorporates a liquid storage tank, a drying tank, and a hanging component into the device. Through the function of the hanging component, multiple pistons can be hung up, and then washed, dried, tinned, and dried again, thereby enabling tinning operations on the surfaces of multiple pistons; ensuring that multiple pistons do not interfere with each other when tinning simultaneously; this utility model has a simple structure, is easy to operate, and can effectively save manpower and material resources and improve work efficiency.
