Embodiment 1

[0014] Such as figure 1 As shown, a simple light shoe tooling for a passenger car bridge includes a bearing seat assembly 1, a connecting block 2 and bolts 3; the connecting block 2 is connected above the bearing seat assembly 1, and the bolt 3 passes through the connecting block 2.

[0015] according to figure 1 As shown, the bearing outer rings are respectively press-fitted on the bearing housings, the invention is installed in place according to the wheel hub assembly method, and a corresponding bearing inner ring is matched on the outer side, and the shaft nut is tightened. Secure the cutter to the bolt. Adjust the tool feed rate and shake the knife arm to achieve smooth cutting of the brake shoe.

Abstract

The invention discloses a simple tool for shoe absence of a passenger train axle. The simple tool comprises a bearing seat assembly (1), a connecting block (2) and a bolt (3), wherein the connecting block (2) is connected above the bearing seat assembly (1); and the bolt (3) passes through the connecting block (2). When the simple tool is in use, bearing outer rings are pressed on a bearing seat respectively, the simple tool is arranged at a proper place in a hub assembly way, a corresponding bearing inner ring is assembled on an outer side, and a spindle head nut is screwed. A cutter is fixedly arranged on the bolt. The cutter feeding amount is adjusted, and a cutter arm is shaken to realize finishing of a brake shoe. The simple tool is a convenient and effective hub shoe absence tool, and can be used for effectively solving the problem of low production efficiency caused by heaviness of a hub and long procedure time during shoe absence of the hub of the passenger train axle.

Description

technical field [0001] The invention relates to a simple bare shoe tooling for passenger car bridges. Background technique [0002] Drum brakes are the earliest form of brakes. Before disc brakes appeared, they have been widely used in various types of automobiles. However, due to structural problems, they have poor heat dissipation performance and small braking contact area during braking. Decreased braking efficiency. [0003] In order to maintain good braking efficiency, a sufficient contact area and an optimal clearance value must be ensured between the brake shoe and the brake drum, and the brake clearance must be the premise that the brake drum and the brake shoe have sufficient contact area Therefore, it is often necessary to lightly cut the brake shoe when installing the brake. In the bare hoof process, the wheel hub must be assembled first, which is cumbersome and inefficient, and the labor intensity is high. Contents of the invention [0004] The technical pro...
