Problems solved by technology

In foreign countries, manufacturers usually use expensive equipment to directly grind the inclined groove and straight groove of the plunger. The plunger processed by this method has stable dimensions and no burrs on the surface; in China, more Manufacturers usually mill the plunger chute and straight groove before heat treatment, and then grind the chute with a common tool grinder after heat treatment. The size of the plunger processed by this method is not easy to guarantee. The chute and straight groove Burrs are prone to appear at the interface and are not easy to remove completely

Abstract

The invention discloses a processing device for directly grinding an inclined groove and a straight groove of a plunger piston, which comprises a machine tool body and a cooling filter, wherein a work table, a transmission device, a grinding device and a control cabinet are arranged on the machine tool body, the cooling filter is arranged on the machine tool body and consists of a cooling spray head, a cooling pipe, a water collection pipe, a water pump and a cooling box, the grinding device comprises an electronic grinding head, a grinding rod is arranged on a main shaft of the electronic grinding head, a cubic boron nitride (CBN) grinding wheel is arranged on the grinding rod. The device can be more conveniently and accurately used for processing the inclined groove and the straight groove of the plunger piston, in the cutting process, the damage occurring in the grinding process is avoided through the cooling filter, the burrs are eliminated, the normal use of products in a diesel engine is ensured, and simultaneously, the production efficiency is improved.

Description

technical field [0001] The invention relates to a processing device capable of directly grinding plunger chute and straight groove. Specifically, it relates to an ordinary tool grinder, which realizes grinding of plunger chute and straight groove by improving and adding corresponding accessories. direct grinding. Background technique [0002] The plunger coupler is an important part in the fuel injection system of a diesel engine. Its function is to convert the low-pressure fuel provided by the fuel pump into high-pressure fuel and deliver it to the injector assembly. When the plunger pair is working, it can provide fuel with different amounts of fuel to the injector assembly according to the different positions of the plunger chute, so the precision of the plunger chute will affect the performance of the diesel engine. In foreign countries, manufacturers usually use expensive equipment to directly grind the inclined groove and straight groove of the plunger. The plunger pr...
