A special processing and positioning device for valve body

Abstract

The invention relates to the technical field of valve processing, in particular to a valve body special-purpose processing and upper positioning device, a rotating motor, a mounting base installed on the rotating shaft of the rotating motor, a mounting vertical plate vertically installed on the mounting base, and the first valve body. The port is attached to the installation vertical plate, and the clamping mechanism and the deviation correction mechanism are installed on the installation vertical plate. The clamping mechanism is used to clamp and fix the valve body on the installation vertical plate, and the valve body is grasped and fixed by using the clamping mechanism During the process, the connecting ends on both sides of the valve body are held and fastened simultaneously by using the holding claws and positioning claws in the deviation correcting mechanism, so that the axis of the connecting ends is set horizontally to ensure that the flanges of the connecting ends are vertical. Straight setting is convenient for subsequent precise processing, and solves the technical problem of low processing accuracy of the connection end caused by clamping and fixing.

Description

technical field [0001] The invention relates to the technical field of valve processing, in particular to a valve body special-purpose processing top-loading and positioning device. Background technique [0002] Before the valve body is processed, it needs to be locked and positioned by positioning tooling. However, due to the specificity of the shape of the valve body, during the process of locking and positioning the valve body, it is very easy to cause the interface ends on both sides of the valve body to be locked during the upper assembly process. , its axis cannot be kept horizontal, resulting in errors when turning or drilling the interface end. [0003] In the Chinese patent with the patent number CN201710561184.2, a fourth-axis rotary indexing processing device for a special machining center for pump covers is disclosed, including a rotary indexing component, which realizes the function of rotating and indexing the workpiece according to the preset angle requirement...

Problems solved by technology

[0005] In view of the above problems, the present invention provides a valve body special-purpose machining and upper positioning device. During the process of grasping and fixing the valve body by using the clamping mechanism, the clamping claw and the positioning claw in the deviation correction mechanism are simultaneously used to align the two sides of the valve body. The side interface ends are hugged and fastened, so that the axis of the interface end is set horizontally, ensuring that the flanging of the interface end is vertically set, which is convenient for subsequent precise processing, and solves the low processing accuracy of the interface end caused by clamping and fixing. technical issues
