Description

Auxiliary tool for machining brake box body of locomotive unit of radial bogie

Technical Field

The utility model relates to a unit brake processing technology field especially relates to a utensil is assisted in processing of radial bogie locomotive unit brake box.

Background

In response to the development of high speed and heavy load locomotives, the end 1996 industry decided to develop radial bogie locomotives. The locomotive has great advantages when being used on a line with more curves and small curvature radius. When the locomotive passes a curve, the wheel pair automatically generates radial displacement according to the size of the curvature radius, so that the dynamic performance of the locomotive when the locomotive passes the curve is improved, and the abrasion of the wheel rim is greatly reduced. The minimum design value of the radius of curvature of the radial bogie locomotive developed by the inventor is 120 meters, and the radial displacement of the wheel set reaches 17 millimeters, which puts high requirements on a braking device. The radial bogie brake unit is developed and researched by a project research group formed by combining the tool and the die with a factory and a design department. The designed novel brake is called a bilateral brake shoe braking unit, and the operation test in the section shows that the novel brake can meet the requirements of normal operation of a wheel set at a radial position, no error action after braking on a curve, uniform brake shoe gaps on a main line of a railway, and the requirements of railway application and the expected purposes and various requirements of design task books. Double-sided brake shoe brake units have now entered the mass production phase. The box body of the brake unit is the installation foundation of each part and component of the brake unit and is also the main receptor of the braking force. The structure is more complex, and each processing part has more relevant sizes. During production it has been found difficult to ensure the geometric requirements of the box with respect to each other in a series of mutually angled planes and apertures. Normally, all processing cannot be finished by one-time clamping on a machine tool. And clamping for many times can cause not small repeated positioning errors even if the same positioning reference is adopted, and finally the product quality is difficult to ensure.

Whether the brake production can be carried out in order influences the delivery of the locomotive on time. In order to economically and quickly solve the problem, a special auxiliary tool is designed, and all related processing can be completed only by clamping once.

After the workpiece is clamped on the machine tool, the four-direction processing is needed. The machining direction of the machine tool spindle is fixed, and the auxiliary tool must have a rotating function in order to meet machining requirements. Meanwhile, in order to make the processing stable and reliable, the auxiliary tool must be fixed on a workbench of the machine tool, and the auxiliary tool is heavy and inconvenient to carry. Therefore, a radial bogie locomotive unit brake housing machining auxiliary tool needs to be designed to solve the problems.
