Abstract

An internal swelling reverse hooking mechanism for a turbocharging exhaust manifold and a turbine casing comprises a seat body device, a first hydraulic device, an in-sleeve transmission device, a positioning press claw device and a second hydraulic device, wherein one end of the in-sleeve transmission device is connected with the positioning press claw device, and the other end of the in-sleeve transmission device penetrates through the seat body device and then is connected with the first hydraulic device; the second hydraulic device is mounted on the seat body device; a boosting end of the second hydraulic device is located between the seat body device and the positioning press claw device. The mechanism has the beneficial effects as follows: in the machining process of the turbocharging exhaust manifold and the turbine casing, the positioning effect is improved, so that the machining accuracy of parts is improved.

Description

technical field [0001] The patent of the present invention relates to a positioning device, in particular to an internal expansion anti-hook mechanism for a turbocharged exhaust manifold and a turbine casing. Background technique [0002] In the processing of the turbocharged exhaust manifold and turbine housing, the exhaust A surface 71 is usually processed by two points on the B surface 72 and two points on the C surface 73, and the E surface 75 and the D hole 74 are positioned. Then use the processed exhaust surface A surface 71 to locate, and process the E surface 75. However, due to blank casting errors, and the inner cavity surface F surface 76 is not machined, the size of the part G position 77 processed in this way is not uniform, the exhaust surface A surface 71 and the turbine inner cavity surface F surface 76 are not perpendicular, and the part's Manufacturing precision is not high. [0003] This requires a positioning device that is more suitable for the machin...
