Description
Technical Field
[0001] This invention relates to a processing device for brake master cylinder components in automotive braking systems, and more particularly to a riveting device for piston components of a plunger-type brake master cylinder. Background Technology
[0002] The master cylinder is a key component of the vehicle's braking system. Its main function is to apply the force of the pedal to the piston of the master cylinder, which is then amplified by the vacuum booster and used to move the piston forward. This generates hydraulic pressure in the pressure chamber of the master cylinder, which is then supplied to the vehicle's braking system through the master cylinder outlet, thereby achieving the vehicle's braking function.
[0003] Early brake master cylinders were mostly of the center valve type and compensating hole type, containing two piston components. Both piston components had springs controlling their return position. One spring was fixed to the piston via a limit seat and limit screw, forming the piston component. As vehicle braking systems gradually upgraded, requiring larger brake master cylinder displacement and stable hydraulic output, the brake master cylinder evolved into the current plunger type structure, such as... Figure 8 As shown, the piston component of the plunger type structure is a riveted structure, and the riveting method is manual riveting. This cannot guarantee the consistency of component height, affecting product quality. Due to the different types and sizes of products, manual riveting requires the use of different tooling and auxiliary equipment. Both piston components of a brake master cylinder assembly require auxiliary equipment, which is made of steel. Manual riveting is labor-intensive for operators, consuming manpower and resources, and increasing the workload of operators. Summary of the Invention
