Description

Technical Field

[0001] This utility model relates to the field of drilling, reaming and chamfering, and specifically to a device for reaming, drilling and chamfering. Background Technology

[0002] In existing technologies, drilling, reaming, and chamfering are often required on sheet metal. For example, the anti-hunting damper of the high-speed train bogie system is installed below the anti-hunting damper mounting base on the car body. The mounting surface is a thick aluminum alloy plate, approximately 16mm thick. The mounting surface has five 24mm diameter holes, four for bolt installation and one for process positioning. During long-term operation of the high-speed train, due to the harsh operating environment, including high temperature and humidity, corrosion defects occur in the aluminum alloy base material inside the holes. During advanced maintenance of the high-speed train, if severe corrosion is found, the corroded base material around the holes is removed, and then the aluminum alloy plate is welded and the holes are re-drilled. The current construction process is as follows: First, using the center of the hole as a reference, a hole reamer is used to remove the base material around the hole; second, a planer or rotary file is used to bevel the base material, and the aluminum alloy plate is re-welded; third, after welding the aluminum alloy plate, a magnetic drill is used to re-drill the hole. This method has the following problems: 1. When EMU trains are under maintenance, the maintenance site is not fixed, and fixed equipment cannot be used for the operation; 2. When using manual processing, the base material around the eye hole is removed using a pneumatic tool equipped with a hole expander. Manual operation cannot guarantee the verticality of the working surface, often resulting in eccentricity. When re-welding aluminum alloy sheets, the welding surface needs to be beveled. This is done manually using a pneumatic tool equipped with a planer. Manual operation cannot guarantee the bevel angle and may result in overcutting of the base material. After re-welding the aluminum alloy sheets, holes need to be re-drilled using a magnetic drill. First, an iron template is installed below the mounting surface of the anti-hunting shock absorber seat, and then the magnetic drill is installed below the template for operation. The process is cumbersome, and the magnetic drill is heavy, making manual operation time-consuming and labor-intensive. If there is a power outage, the magnetic drill may fall off.
