Positioning mechanism for machining holes in end surfaces of inner gear rings

Abstract

The invention discloses a positioning mechanism for machining holes in the end surfaces of inner gear rings. The positioning mechanism comprises a base. A tank is mounted on the upper side of the base, a water tank is mounted inside the tank, a high-pressure water pump is mounted inside the water tank, support columns are mounted on the upper side of the tank, hydraulic cylinders are mounted inside the support columns, compression plates are mounted at output ends of the hydraulic cylinders via piston rods, a support frame is mounted above the tank and is positioned on a side of each support column, a filter screen is arranged on the surface of the tank and is positioned at the bottom of the support frame, a first mounting plate is mounted on the tops of the support columns, a drilling structure is mounted in the center of the bottom of the first mounting plate, a second mounting plate is mounted on the lower side of the drilling structure, and drill bits are mounted at the bottom of the second mounting plate. The positioning mechanism has the advantages that the positioning mechanism comprises the hydraulic cylinders, the compression plates, the high-pressure water pump and a high-pressure spray nozzle structure, and accordingly the inner gear rings with optional sizes can be clamped by the positioning mechanism and can be washed by high-pressure water flow.

Description

technical field [0001] The invention relates to the technical field of ring gear processing, in particular to a positioning mechanism for processing the end face of an inner ring gear. Background technique [0002] The inner ring gear refers to the inner gear with the same axis as the planet carrier in the planetary gear transmission. The inner ring gears used in automobiles and construction machinery are mostly medium carbon alloy steel quenched and tempered nitriding process or low carbon alloy steel carburizing and quenching process. And most of them are thin-walled parts, there are large machining deformation and heat treatment deformation in the processing process, and it is difficult to meet the accuracy requirements. In order to improve the precision of the inner ring gear, it is necessary to improve the machining accuracy before heat treatment and reduce the heat treatment deformation. When the hole is being processed, the inner hole plate of the ring gear needs to b...
