Centrifugal pump shell processing jig

Abstract

The invention discloses a jig for processing a centrifugal pump shell, which comprises a fixed frame, a pressing mechanism, a rotating mechanism and a clamping mechanism. Connection, the pressing mechanism is connected with the clamping mechanism, the fixed frame includes the bottom plate, the supporting plate, the fixing plate, the chute, the threaded hole, the positioning rod, the rectangular frame, the rotating tray and the connecting plate, the fixture of the centrifugal pump shell, the pressing mechanism , the rotation mechanism and the clamping mechanism are combined in turn, the setting of the connecting sleeve can meet the rotation requirements of the second rotating shaft, the setting of the limit slide bar and the linear groove can meet the sliding requirements of the collar when the central rotating shaft rotates, so that Each mechanism can operate independently, and each operating mechanism does not need to load the weight of other driving equipment. The coordination effect of each mechanism is good, and the space utilization rate is high. The pump body is fixed by fixing the flange, and the specific clamping model is avoided to effectively fix the pump body. disadvantages.

Description

Technical field: [0001] The present invention belongs to a clamping device, and more particularly to a centrifugal pump housing processing fixture, which belongs to the field of centrifugal pump production. Background technique: [0002] The structure of the centrifugal pump is complex. The castings account for more than 80%, mainly cast iron parts, cast steel parts and cast stainless steel parts, less shaft parts, mainly high quality carbon steel, chrome steel or stainless steel, centrifugal pump parts processing Because it has a hydraulic flow path, it is necessary to find the correct position of the flow path in consideration of the positioning equipment, and avoid assembly, which causes the spline and impeller flow path to be skewed, mishanded, gap is not even touched, affecting the product Quality, in order to ensure that parts manufacturing accuracy, need to design the corresponding tooling, and arrange the process flow reasonably. [0003] In the comparative document of Pa...

AI Technical Summary

Problems solved by technology

[0004] 1. The fixture of the centrifugal pump casing has a single function. Generally, it only has the function of clamping and positioning, and requires a pump body with multiple processing surfaces perpendicular to the same reference plane. The practicability is not wide enough.

[0005] 2. The centrifugal pump casing fixture is equipped with a multi-stage angle adjustment mechanism. The secondary angle adjustment mechanism requires additional equipment to adjust the angle of the pump body. The space utilization rate is low, and the operation of each structure is poor.
