Pore burr removing device

Abstract

The invention belongs to the field of a machining device, in particular to a pore burr removing device used for removing burrs in a pore of a high-pressure oil channel of an oil sprayer body. The pore burr removing device is characterized in that a motor is arranged on a rack, and one end of a screw is arranged on the upper side of the rack through a bearing and a bearing block; the motor is connected with a belt pulley at one end of the screw through a belt; two guide columns are arranged in the rack and are sleeved in an insulating support plate; the other end of the screw penetrates through the insulating support plate and is connected with the insulating support plate through nuts; the insulating support plate is provided with one or more workpiece fixing pore(s), a metal conductive copper sleeve is embedded in the fixing pore(s); and the lower side of the rack corresponding to the fixing pore(s) is provided with an electrode, and the part of the electrode under the tip is coated by an insulating material. Therefore, the pore burr removing device has the advantages that the pore burr removing device has a simple structure, the burrs in the fine and long pores can be completely removed, the finish of the pores can be improved, and the efficiency is high.

Description

Technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a deburring device mainly used for deburring a high-pressure oil passage hole of a fuel injector body. Background technique [0002] At present, one of the high-pressure oil passage holes of the injector body is processed with a twist drill. The disadvantage is that there are many small burrs in the drilled hole that adhere to the wall of the hole. The oil passage hole is a slender hole and cannot be used normally. Reaming and grinding remove the burrs in the holes, causing the burrs to fall off and block or jam the needle valve of the injector under the impact of high-pressure oil in the injector oil passage, which affects the atomization performance of the injector and makes the engine Smoke and fire power is reduced; the other is to use gun drill processing, although the effect is good, but the equipment is expensive and the processing cost is high.

[0002] At present, one of the high-pressure oil passage holes of the injector body is processed by a twist drill. The disadvantage is that there are many small burrs sticking to the hole wall in the drilled hole, and the oil passage hole is a long and thin hole, which cannot be The reaming and grinding remove the burrs in the hole, which will cause the burrs to fall off and block or block the needle valve of the injector under the impact of high-pressure oil in the oil passage of the injector, which will affect the atomization performance of the injector and make the engine The power of smoke and fire is reduced; the other is to use gun drilling, although the effect is good, but the equipment is expensive and the processing cost is high
