A fixed tooling for shell processing

Abstract

The invention relates to the technical field of clamping tooling for machining, and provides a fixed tooling for shell processing, including: a support seat; a clamping assembly, the clamping assembly has: at least three movable jaws, the movable jaws are arranged at on the support seat, and can be switched between the first position and the second position on the support seat, and the upper end of each movable jaw is provided with a pressing part; the driving part is arranged in the support seat and connected to each movable The lower end of the jaws; when the driver drives each movable jaw to switch from the second position to the first position, the pressing part presses the upper surface of the shell to be processed to fix the shell on the tooling. Compared with the prior art, the advantage of the present invention is that by setting the pressing part on the upper end of the movable jaw, and then driving the movable jaw to switch positions through the driving part, the pressing part is pressed on the upper end of the housing to complete the installation of the housing on the tooling. Fixed, so that the casing will not be crushed while the casing is fixed.

Description

technical field [0001] The invention relates to the technical field of machining fixing tooling, in particular to a fixing tooling used for shell processing. Background technique [0002] The shell is a relatively common mechanical part. The production of the shell is generally done by casting to complete the shape of the shell, and then machining to complete the structure on the shell that cannot be completed by casting. During the machining process, the structure is more complicated. The shell needs to be fixed on the machine tool with a more complex fixing tool, and the shell with a regular-shaped through hole in the middle is mostly fixed in the through hole in the middle of the shell with a three-jaw chuck to realize the fixing of the shell, but Most of the traditional three-jaw chucks are used to fix the casing by pressing against the side wall of the through hole in the middle of the casing. Such an operation can easily cause damage to the casing with a thin hole wall...

[0002] The shell is a relatively common mechanical part. The production of the shell is generally to complete the shape of the shell through casting, and then complete the structure on the shell that cannot be completed by casting through machining. During the machining process, the structure is more complicated. The housing needs to be fixed on the machine tool with more complicated fixing tools, and the housing with a regular-shaped through hole in the middle is mostly fixed in the through hole in the middle of the housing by a three-jaw chuck to achieve the fixing of the housing, but Most of the traditional three-jaw chucks fix the shell by pressing against the side wall of the through hole in the middle of the shell. Such an operation is easy to cause damage to the shell with a thin hole wall, which is not conducive to the processing of the shell.
