Fixing clamp for water pump impeller surface finish machining

Abstract

The invention provides a fixing clamp for water pump impeller surface finish machining, and relates to the technical field of water pump impeller machining. The problems that in the actual applicationprocess of an existing impeller clamp, due to the fact that the feeding path of a cutter needs to be considered when a CNC machine tool is used for machining an impeller, the outer side of the impeller is clamped, normal machining of the machine tool is influenced, moreover, the clamping manner is quite single, the impeller clamp has no variability in the using process, and the impeller clamp cannot adapt to finish machining of water pump impellers of different specifications are solved. The fixing clamp comprises a driving mechanism, and the driving mechanism is installed at the front end position of a bearing and positioning mechanism. In the fixing clamp, positioning discs of different types can be connected to the outer side position of a limiting column at the top end of a bearing base in an inserted manner according to actual needs, two clamping jaws are driven to move inwards at the same time through engagement transmission between two driven gears and two racks till two inserting blocks can be clamped with square grooves formed in the left sides and the right sides of the outer circumferential faces of the positioning discs, and the aim of improving the working efficiencycan be achieved.

Description

technical field [0001] The invention belongs to the technical field of water pump impeller processing, and more specifically relates to a fixing fixture for finishing the surface of a water pump impeller. Background technique [0002] The water pump impeller is made of cast iron, and the blades on the water pump impeller play a major role. The shape and size of the water pump impeller are closely related to the performance of the water pump. Generally, the water pump impeller can be divided into two types: single-suction type and double-suction type. For unilateral water absorption, small flow pump impellers are mostly of this type, double-suction impellers are for both sides of water absorption, and large-flow water pump impellers all use double-suction impellers. The impeller is the core component of the pump and is the main factor affecting the working efficiency. Under certain working conditions, if the impeller design is not good, hydraulic loss and clearance loss will ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a fixed fixture for finishing the surface of the water pump impeller to solve the problem that the existing impeller fixture needs to consider the tool path when machining the impeller with a CNC machine tool in the actual application process. , so clamping the outer side of the impeller will affect the normal processing of the machine tool, and the clamping method is relatively simple, so there is no flexibility in use, and it cannot be adapted to the problem of finishing of water pump impellers of different specifications
