Drilling machine for machining crankshaft inclined oil hole of engine

Abstract

The invention relates to a drilling machine for machining a crankshaft inclined oil hole of an engine. The drilling machine for machining the crankshaft inclined oil hole of the engine comprises a machine body, a clamping device, inclined oil hole drilling devices, a power source control cabinet and a numerical-control control cabinet, wherein the clamping device and the inclined oil hole drilling devices are installed on the machine body, the numerical-control control cabinet is arranged on the power source control cabinet, and the numerical-control control cabinet is connected with a stepping motor of each inclined oil hole drilling devices through a guide wire. According to the drilling machine for machining the crankshaft inclined oil hole of the engine, a pneumatic device which is applied to the clamping device replaces a traditional tool, and the inclined oil hole drilling devices are controlled through a numerical control system and replace a radial drilling machine which is tedious in operation. Therefore, the drilling machine for machining the crankshaft inclined oil hole of the engine can effectively relieve the labor intensity of operating workers, can achieve one-time clamping and synchronous cutting of multiple inclined oil holes by means of the additional arrangement of the inclined oil hole drilling devices on the two sides of the clamping device, enables the efficiency of hole drilling to be greatly improved, and effectively improves working efficiency.

Description

[0001] technical field [0002] The invention relates to mechanical processing equipment, in particular to a drilling machine for processing oblique oil holes of engine crankshafts. Background technique [0003] The crankshaft of a gasoline and diesel engine is an important part of the engine, and almost every crankshaft is designed with an oblique oil hole. Since the oblique oil hole connects the crankshaft main shaft and the connecting rod, due to its irregular offset angle and position, it is difficult to process. very high. The processing technology currently used is generally completed by radial drilling machines with self-made positioning tooling. The characteristics of radial drilling machines determine that during the process of drilling inclined oil holes, workers must continuously adjust the position of the rotary arm and rotate it. The handle allows the drill bit to drill into the crankshaft bit by bit to complete the drilling of a single hole, and the crankshaf...

[0003] The crankshaft of a gasoline and diesel engine is an important part of the engine, and almost every crankshaft is designed with an oblique oil hole. Since the oblique oil hole connects the crankshaft main shaft and the connecting rod, due to its irregular offset angle and position, it is difficult to process. very high

The processing technology currently used is generally completed by radial drilling machines with self-made positioning tooling. The characteristics of radial drilling machines determine that during the process of drilling inclined oil holes, workers must continuously adjust the position of the rotary arm and rotate it. The handle allows the drill bit to drill into the crankshaft bit by bit to complete the drilling of a single hole, and the crankshaft has multiple oblique oil holes. Usually, to process a crankshaft, the steps of positioning drilling need to be repeated three or four times, which makes the workers laborious. The strength is particularly high; the tooling used in the processing process is simple self-made tooling. Every time the workpiece is replaced, it must be manually released and clamped. The steps are cumbersome and the efficiency is very low. It is difficult to achieve multiple The consistency of the hole position is not easy to meet the technical requirements of the product, let alone the actual production needs of modern enterprises
