Abstract

The invention relates to a grinding process method of a pump body valve hole of a steering pump, belongs to the technical field of grinding process and aims to provide a process method used for improving the grinding precision of a pump body valve hole of a steering pump. The technical scheme adopted by the invention is as follows: the grinding process method of the pump body valve hole of the steering pump is characterized by being implemented through the following steps: step 1, fixing a diamond reamer on a horizontal grinding machine; step 2, holding the pump body of the steering pump by hand, and sleeving the valve hole of the pump body of the steering pump on the diamond reamer; step 3, rotating the diamond reamer, and supporting the pump body to grind the valve hole by hand; and step 4, after finishing the grinding of the valve hole of the pump body of the steering pump, stopping rotating the diamond reamer, and taking down the pump body of the steering pump. The valve hole grinded through the method has the advantages of no slight degree and high precision of cylindricity; and the time of installing workpieces and clamping the workpieces can be omitted, and the production efficiency is high.

Description

A kind of grinding process method of steering pump pump housing valve opening
Technical field
The grinding process method of a kind of steering pump pump housing of the present invention valve opening belongs to the grinding process technical field.
Background technology
Traditional handicraft is that workpiece is fixed on the cross grinding machine when grinding steering pump pump housing valve opening, comes grinding with inner bore grinding head.This method is because of the small sway of cutter itself, and the valve opening that grinding goes out has degree slightly, and promptly oral area is big slightly, and the cylindricity precision is low, and the time that the installation clamping work pieces needs is long, and production efficiency is low.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of process that improves steering pump pump housing valve opening grinding accuracy.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of grinding process method of steering pump pump housing valve opening is characterized in that carrying out according to following steps:
The first step is fixed on diamond reamer on the cross grinding machine;
In second step, the hand-held steering pump pump housing is enclosed within the valve opening of the steering pump pump housing on the described diamond reamer;
The 3rd step, rotate described diamond reamer, the hand steered pump housing comes the grinding valve opening;
In the 4th step, after the grinding of steering pump pump housing valve opening was accomplished, the described diamond reamer that stops the rotation took off the steering pump pump housing.
The present invention compares the beneficial effect that is had with prior art: during the rotation diamond reamer; The hand-held steering pump pump housing; The steering pump pump housing can float along with the rotation of diamond reamer is small, and the valve opening that goes out of grinding is not with slightly and is spent like this, and the cylindricity precision is very high; And saved the time that the workpiece clamping work pieces is installed, production efficiency is high.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the structural representation of the diamond reamer used in the method for the invention.
Among the figure, 1 is handle of a knife, and 2 is endoporus, and 3 is valve opening, and 4 is cutter head, and 5 is radial hole.
The specific embodiment
A kind of grinding process method of steering pump pump housing valve opening, carry out according to following steps:
The first step is fixed on diamond reamer on the cross grinding machine;
In second step, the hand-held steering pump pump housing is enclosed within the valve opening of the steering pump pump housing on the described diamond reamer;
The 3rd step, rotate described diamond reamer, the hand steered pump housing comes the grinding valve opening;
In the 4th step, after the grinding of steering pump pump housing valve opening was accomplished, the described diamond reamer that stops the rotation took off the steering pump pump housing.
Described diamond reamer comprises handle of a knife 1 and cutter head 4; Cutter head 4 is connected on the handle of a knife 1, has at least one skewed slot on the cutter head 4, has axial bore 2 on cutter head 4 and the handle of a knife 1; Be provided with a plurality of radial holes 4 on each skewed slot of said cutter head 4, and each radial hole 4 communicates with endoporus 2 all.In the grinding process of steering pump pump housing valve opening, grinding fluid gushes out in the radial hole 5 through the axial bore on the diamond reamer 2 and cools off, and effectively reduces the frictional heat that produces in the process, and then has improved the machining accuracy in processed hole.
