Embodiment Construction

[0032] The present invention is described in further detail below in conjunction with accompanying drawing:

[0033] In this embodiment, the engine low-pressure casing is taken as an example. The casing 8 is a cylindrical shell, and the inner wall is provided with several stepped surfaces along the circumference. The material of the casing body is 1Cr12Ni3MoVN. 3Gr13, so that the entire supporting device expands as much as the casing 8 during welding and heat treatment, ensuring accurate, reliable and effective support.

[0034] Such as figure 1 As shown, the supporting device is arranged inside the casing 8 to effectively support the casing 8 in the radial direction, including a pillar 2, at least one positioning plate 1 and an adjustment mechanism.

[0035] Such as figure 2 As shown, the pillar 2 is located at the center of the axis, and adopts a hollow cylindrical tube, and the two ends are welded with a cover plate, and a lifting nut is installed on the cover plate, so ...

Abstract

The invention discloses a supporting device for engine case machining. The supporting device comprises a positioning plate, a pillar and an adjusting mechanism. The positioning plate is connected to the pillar in a sleeving mode. The positioning plate is provided with at least two extending plates extending radially, and the extending plates are evenly distributed in the circumferential direction.The adjusting mechanism comprises a baffle block, a wedge block and an ejector block arranged in sequence from the pillar to the free end of the positioning plate. The baffle block is fixedly arranged. The wedge block is used to jack the ejector block outward. The ejector block is provided with a guide seat. Both ends of the guide seat are fixedly arranged on the extending plates, and the middleof the guide seat is arched to form a groove for the ejector block to pass through. The supporting device is set inside the case, the case is effectively supported radially, and the support can be adjusted by the adjusting mechanism according to the actual processing size of the inner wall of the case, so that the effective support of all the inner walls of the cases within the tolerance range isachieved. By means of the supporting device for engine case machining, effective supporting and reducing deformation in the process of welding and post-welded heat treatment of large-size case accessories are achieved, and the manufacturing qualification rate of this type of the case is greatly improved.

Description

technical field [0001] The invention belongs to the field of engine manufacturing and assembly, and relates to an engine case processing support device. Background technique [0002] In order to simplify the structure, the connection process between various accessories (supports) outside the casing and the casing body is usually designed as a welding connection in the design of the engine casing. Due to the large number of welding accessories, if the size of the casing is large, it is easy to cause deformation of the casing. It is necessary to use a reliable and convenient process support device to effectively support the welding and post-weld heat treatment of the casing accessories to control the process. The deformation of the casing meets the requirements of this type of casing welding and heat treatment deformation control process to ensure the qualified delivery of the casing. Contents of the invention [0003] The purpose of the present invention is to overcome the...
