Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and in particular to a clamping system used in the machining process of split-case pumps. Background Technology

[0002] Currently, the processing of split-case pumps is carried out in stages on different equipment. In particular, the mechanical seal, bearing, and inlet ring positions are processed by combined processing (after the pump body and pump cover are fixedly connected, the processing is carried out inside the split-case pump). Specifically: First, the bottom corners, connecting holes, and flanges on the outside of the entire split-case pump are processed. Then, the processing tool is inserted into the inside of the split-case pump to process the inlet ring, mechanical seal, bearing, and other structures.

[0048] In this embodiment, the first clamp, the second clamp, and the third clamp are respectively used to clamp different components of the split-case pump during the processing. The first clamp is used to clamp the lower pump body of the split-case pump during the first processing step. After the first processing step of the lower pump body is completed, the lower pump body is flipped and fixed onto the second clamp for the second processing step. The third clamp is used to clamp the pump cover of the split-case pump during the third processing step. By clamping different components of the split-case pump during the processing with the first clamp, the second clamp, and the third clamp, different parts of the split-case pump can be processed separately, thereby improving the processing accuracy, increasing processing efficiency, and reducing processing costs.

[0049] In an optional embodiment of the present invention, the first clamp is described, and the first clamp may include:

[0050] First base 1;

The inlet and outlet flanges in the lower pump body of the pump are engaged with the second slot 22. Then, the first frame of the first gantry 2 is rotated to a horizontal position so that the first slot 21 and the second slot 22 cooperate to fix the inlet and outlet flanges in the lower pump body of the split-case pump. Preferably, the second slot 22 is provided with a first protrusion structure 221, which is symmetrically distributed on both sides of the second slot 22 to increase the friction between the inlet and outlet flanges in the lower pump body of the split-case pump and the second slot 22, and to prevent the split-case pump from sliding during processing.
