[0002] The brake shoe is the friction component of the drum brake. In addition to having the strength and rigidity required as a component, it should also have the highest possible and stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. During the processing of the brake shoe, a drilling device is required to process it and process the mounting holes on the brake shoe.

[0023] In the present invention, when the device needs to be used, the brake shoe is placed on the limit platform 2, and it is fitted with the arc-shaped notch on the limit platform 2, and the support of the brake shoe is completed by the limit platform 2, and the brake shoe can be fitted and rotated on the limit platform 2. After the brake shoe is supported, the second limit component is used to limit the brake shoe in the horizontal direction, and the brake shoe is preliminarily positioned so that its position can better cooperate with the first limit component. After completing the preliminary positioning of the brake shoe, the brake shoe is limited in the circumferential direction by the first limit component, so that the brake shoe cannot continue to be positioned on the limit platform. 2, and after the brake shoe is further limited by the first limiting component, the working position is located at a fixed position and cannot be changed, which is equivalent to further positioning the brake shoe. The driving component drives the drilling component to drive the drilling component close to the brake shoe to complete the drilling operation on the brake shoe. The device can effectively limit the brake shoe, thereby improving the stability of the brake shoe when drilling, and in the process of limiting the brake shoe, it can also position the brake shoe in disguise, thereby improving the accuracy of the work during processing.
