Cross hole deburring device

Abstract

The invention relates to the field of deburring devices, and discloses a cross hole deburring device. The device comprises a rack and a clamp for clamping workpiece; the clamp is arranged on the rack;the rack is also provided with a high-pressure flushing device, the high-pressure flushing device comprises a high-pressure water pump, a nozzle and a flexible spraying pipe, one end of the spray pipe communicates with a water outlet of the high-pressure water pump, the nozzle is arranged at the other end of the spray pipe, and the nozzle communicates with the spray pipe; the nozzle is cylindrical, a plunger is arranged in the nozzle, and the plunger is coaxial with the nozzle; and a spiral water passing hole is formed in the plunger in the axial direction of the plunger, and the two ends ofthe water passing hole penetrate through the two ends of the plunger. According to the cross hole deburring device, the burr is removed by the high-pressure water flushing cross hole, and the slag return phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of deburring devices. Background technique [0002] In the process of manufacturing workpieces such as hoods, engine blocks, and gearbox blocks, due to the need to set oil passages, it is necessary to drill intersecting holes on the workpieces, that is, cross holes, and in the process of drilling. Burrs are generated at the intersection of the holes. If the burrs are not removed properly, the remaining burrs will seriously affect the subsequent assembly and performance of the workpiece. [0003] The latest deburring methods, such as thermal deburring, abrasive water jet deburring, ultrasonic deburring, robot deburring, etc., have the common disadvantages of large equipment investment, high operating costs, and low economic benefits. At present, the most economical and effective method is to use high-pressure water for flushing. However, when high-pressure water is used to flush the intersection along one end opening ...
