Rail vehicle frame air spring hole anti chip tooling

Abstract

The invention relates to a chippings preventing tool for air spring holes of a framework of a railway vehicle. The chippings preventing tool for the air spring holes of the framework of the railway vehicle is provided with baffles which are arranged symmetrically, wherein the outer side surface of each baffle is a curved surface which is suitable for being attached to the inner side surface of a lower hole of an air spring; a positioning block which is suitable for being inlaid in a notch of the lower hole of the air spring is fixed on the outer side surface of each baffle; inner sides of the symmetric baffles are fixed together through a four-bar linkage; when the four-bar linkage is in a folded state, the size of the periphery of the tool is smaller than that of an upper hole of the air spring, so that the tool can be placed in the upper hole of the air spring; and when the four-bar linkage is in an unfolded state, the outer side surface of each baffle is attached to the lower hole of the air spring, and each positioning block is inlaid in the notch of the lower hole of the air spring. With the aid of the tool, an operator can simply operate to accurately position the tool so as to stop iron chippings from entering an additional air chamber, and safety of running is guaranteed. Inner space of the hole of the air spring can be saved effectively, the storage amount of the iron chippings is increased, looseness of the device due to twining and rotating of the iron chippings during machining is prevented, and smooth machining is guaranteed.

Description

technical field [0001] The invention relates to a tooling device for preventing iron filings from entering the interior of the frame for processing the bogie frame of a high-speed rail vehicle. The solution is to prevent the iron filings from entering the additional air chamber of the air spring during the processing of the frame. It belongs to the technical field of a high-speed rail vehicle bogie. Background technique [0002] The additional air chamber of the rail vehicle frame air spring is connected to the mounting hole, and iron filings will enter the air spring additional air chamber during frame machining. The diameter of the upper hole of the air spring is smaller than that of the lower hole of the air spring, and the side wall of the lower hole of the air spring has a gap. When framing and processing, it is necessary to prevent iron filings from entering the gap. [0003] The existing technology is to use cotton cloth for protection, but the use of cotton cloth fo...

Problems solved by technology

[0003] The existing technology is to use cotton cloth for protection, but the use of cotton cloth for protection will bring the following problems: 1. The internal space of the empty spring hole is too small, and the machine is stopped to clean the iron filings too frequently during the processing, which affects the processing efficiency 2. The iron filings will be transferred during the processing The cotton cloth is brought up, which affects the surface processing quality of the hollow spring hole. 3. The complete protection effect cannot be achieved, and some iron filings enter the additional air chamber, which increases the workload and difficulty of the cleaning process.
