Description

Technical Field

[0001] The invention belongs to the technical field of punching equipment, and in particular relates to an automatic punching device for processing automobile brake discs. Background Art

[0002] The car brake disc is one of the key components in the vehicle's braking system. It works together with the brake pads to slow down or stop the vehicle. When the driver steps on the brake pedal, the brake pads are pressed against the sides of the brake disc through a series of mechanical, electronic or hydraulic components. The friction converts the kinetic energy of the wheels into heat energy, thereby achieving the purpose of slowing down or stopping the vehicle. Brake discs are usually made of cast iron. This is because cast iron has good wear resistance and high temperature resistance. In order to improve the heat dissipation and drainage performance of the brake disc and reduce weight at the same time, drilling equipment is usually used to drill holes in the brake disc, as shown in the attached figure. Figure 7 As shown, the existing punching equipment has the following problems when punching: 1. The location where holes need to be punched on the brake disc is on the disc surface. When drilling the disc surface, a single cutting tool is usually used to drill the brake disc. The brake disc usually includes multiple holes, which need to be drilled in sequence using a cutting tool. The drilling efficiency is low, and debris accumulates on the top of the brake disc during drilling, which can easily cause scratches on the brake disc surface. When drilling again, the debris will enter the hole wall with the cutting tool, causing scratches on the hole wall and reducing the structural strength of the brake disc.

[0003] 2. When drilling a hole in a brake disc, it is usually necessary to use a triangular chuck to position and clamp the brake disc. The brake disc is manually clamped to the triangular chuck. After the processing is completed, the material is manually unloaded and a new brake disc is loaded again. Manual loading and unloading is required, which has low work efficiency. Moreover, after clamping with the triangular chuck, the cutting tool is subjected to force on one side to punch a hole, which can easily cause the brake disc to warp and slip in the fixture, resulting in poor clamping stability and reduced drilling accuracy.
