Description

A horizontal machining center tooling for a high-speed train brake system hanger

Technical Field

The utility model relates to the technical field of a hanger tooling for a high-speed motor vehicle brake system, and more specifically to a horizontal machining center tooling for a hanger tooling for a high-speed motor vehicle brake system.

Background technique

The braking system components of high-speed trains are critical to ensure the safe operation of high-speed trains. The braking system is a key part of the safe operation of rail vehicles and plays a key role in vehicle braking. Most of the components of the system are complex in shape, light in weight, high in precision, and have strict quality indicators. Under the high requirements of material performance indicators and quality, the braking system structure also requires precision, so high geometric accuracy is required for each single component. Due to the use of low-temperature resistant ductile iron materials, it is very easy to deform under the action of cutting force and clamping force during the processing. The tooling design in the machining process is very critical to ensure dimensional accuracy and eliminate the influence of deformation on the geometric dimensions of the workpiece, and it is also one of the difficulties in designing tooling.

The hanger is a very important component in the high-speed train braking system. It is installed in the high-speed train braking system. Its main function is to brake smoothly during vehicle operation to ensure the safe driving of the vehicle. At the same time, it can brake the vehicle smoothly when an emergency occurs during high-speed operation. Due to the importance of the hanger, the material selection, processing technology, and even quality control of the hanger are very critical, which has an important impact on the safety of vehicle operation. Therefore, the quality of machining process design is very critical to ensure the stability and consistency of the product. In order to improve production efficiency and ensure the stability of product quality, the blank surface positioning processing method is adopted. In order to prevent the instability of the relevant dimensions of the product caused by multiple clamping, improve production efficiency, and reduce production costs, horizontal machining center equipment is usually used for processing.

However, the hanger adopts the blank surface as the processing reference during the design process. Since the blank is a casting, the traditional process design first determines the reference by marking. During processing, clamping is performed according to the marked reference, and the workpiece is manually clamped after positioning. This method requires high working ability of the operator. Uncertain factors such as alignment accuracy and clamping force during processing pose a great risk to the stability of workpiece quality, a high failure rate, and low processing efficiency. In addition, the relevant position tolerance requirements of each hole identified from the product drawing are very strict, and the tolerance range of each hole is small. If clamped multiple times, the accuracy of the relevant position will be difficult to guarantee, and the positioning accuracy and uniformity and reliability of the clamping force cannot be guaranteed.

Therefore, providing a horizontal machining center tooling for accurately positioning the high-speed motor vehicle brake system hanger is a problem that technical personnel in this field urgently need to solve.
