Embodiment Construction

[0025] like Figure 3~6 Among them, the component housing 7 in the present invention is a thin-walled component with an irregularly shaped inner cavity 16 in the middle. An internal gear 11 is provided in the middle of the inner cavity 16, and stepped holes and reinforcing ribs are provided at the bottom of the part housing 7. The outer contour is irregular, it is difficult to locate and clamp, and the rigidity is poor, and it is easy to deform during processing. . A flange edge 14 is arranged on the top of the part housing 7, and a plurality of flange holes are arranged on the flange edge 14.

[0026] like figure 1 , 2 Among them, a jig for the gear-shaping process of an engine casing includes a jig body 1, and a plurality of support columns 3 for positioning a datum plane are provided on the jig body 1, preferably as figure 1 As shown in , the support column 3 locates the datum plane of the component housing 7 through the upper end surface, and the upper end surface of t...

Abstract

The invention provides a jig for the gear-shaping process of an engine casing, which includes a jig body, on which a plurality of support columns for positioning a datum plane and a plurality of positioning pins for locating the center of a circle are arranged; A rotary compression cylinder, and a positioning support cylinder matched with the rotary compression cylinder. The support column locates the datum plane of the component housing through the upper end surface, and the upper end surface of the support column is supported on the inner hole step of the component housing. There are two positioning pins. The positioning of the end face reference plane is realized by using the support column, and the centering of the part shell is realized through the positioning pin, so as to realize the precise clamping and positioning of the part shell with complex structure. Cooperate with the rotary compression cylinder and the positioning support cylinder to compress the part shell, improve the processing rigidity of the part shell, prevent the deformation of the part shell in the gear shaping process, and improve the gear shaping accuracy of the internal gear in the part shell.

Description

technical field [0001] The invention relates to the field of gear shaping processing, in particular to a jig for the engine housing gear shaping process of engine housings and other thin-walled parts with complex shapes in industries such as automobiles and aerospace industries. Background technique [0002] Engines are vital components in automotive, aerospace, and more. The engine casing is often made of aluminum alloy precision casting, which has the characteristics of light weight, complex shape structure, poor rigidity, and easy deformation. The above-mentioned characteristics often cause processing difficulties in the production and processing of the engine casing. For example, some of them cannot be clamped due to the standard problem, some have poor rigidity and low machining accuracy during machining after clamping, and some have no machine tools that can process this process. In the prior art, there is no fixture specially used for gear shaping of thin-walled par...
