Embodiment Construction

[0021] Specific embodiments of the present invention will be described below.

[0022] The new processing technology for plunger grinding of this embodiment includes the following steps:

[0023] The first step: plunger outer circle processing: prepare the blank, rough grind the outer circle of the blank, perform smooth grinding after rough grinding, and finally finish the outer circle;

[0024] The second step: heat-treat the plunger with the outer circle processed;

[0025] The third step: the plunger after heat treatment adopts CNC grinding machine to process the straight groove;

[0026] Step 4: After the straight groove is processed, the plunger is machined with a CNC grinding machine, and the plunger is clamped once. After one side is processed, it is automatically turned over to process the other side.

[0027] In the first step, the CNC equipment is used to control the feed and retreat of the grinding wheel through the CNC program. The grating ruler is used for posit...

Abstract

The invention relates to a novel machining technology for grinding a plunger. The novel machining technology comprises the following operation steps of step one, machining the outer circle of the plunger; preparing workblank, roughly grinding the outer circle of the workblank, buffing the roughly-ground outer circle, and finally, finely grinding the outer circle; step two, carrying thermal treatment on the plunger of which the outer circle is machined; step three, machining a straight channel in the plunger on which the thermal treatment is carried out by adopting a CNC (Computer Numerical Control) grinding machine; step four, machining a chute in the plunger by adopting the CNC grinding machine after straight channel machining is completed, carrying out one-step clamping, and automatically overturning one surface which is already machined to machine the other surface. The novel machining technology disclosed by the invention is low in production cost and excellent in product quality.

Description

technical field [0001] The invention relates to a novel machining process for plunger grinding. Background technique [0002] At present, in the domestic diesel mechanical pump plunger pair processing industry: the plunger outer circle processing generally adopts the following process: blank → rough grinding outer circle → fine grinding outer circle → smooth grinding outer circle → fine grinding outer circle (with grinding pair) , there are many cylindrical grinding processes, and the process route is long; the cylindrical straight groove of the plunger is generally used for milling with a milling cutter before the heat treatment of the part (the hardness of the part is low); the cylindrical chute of the plunger is generally used After heating, use a corundum grinding wheel to grind on the M7120D surface grinder. The dust in the workplace is very harmful to employees. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing production ...
