Deep hole drilling device for camshaft

Abstract

The invention discloses a camshaft deep hole drilling device which comprises a tailstock, three jaws are arranged on one side of a lathe, the tailstock is arranged on the other side of the lathe, a middle frame is arranged between the three jaws and the tailstock, the tailstock is composed of a bottom plate (16), a support, a drill bit (7), a transmission mechanism, a controller (2) and a positioning mechanism, the bottom plate (16) is fixed to the lathe, the support is arranged on the bottom plate (16), and the drill bit (7) is arranged on the support. The transmission mechanism is arranged on a support of the bottom plate (16), the positioning mechanism is arranged on the bottom plate (16), the controller (2) is arranged on the bottom plate (16), the controller is used for controlling the motor (3) to drive the gear disc (5), the advancing distance and the retreating distance of the sliding barrel (15) are made to be stable, meanwhile, the drill bit (7) is made to be stably and accurately aligned with the drilling position, the finished product rate of deep hole machining of the cam shaft is guaranteed, the labor intensity of workers is reduced, and the machining efficiency is improved. On the premise of guaranteeing the quality of the machining precision of the deep hole of the cam shaft, purchasing of special equipment for drilling the deep hole is avoided, and high cost input brought to enterprises is avoided.

Description

technical field [0001] The invention relates to a camshaft deep hole drilling device. Background technique [0002] The camshaft is an important part responsible for the opening and closing of the valve. It is also an important part for changing the speed of the car in the gearbox. Most of the camshafts are refined from cast iron and carbon steel, and most of them require deep hole processing. [0003] ZL201822142034.0 discloses "a special drilling machine for camshaft deep holes, including a vertical drilling machine and a cam bearing support platform, the cam bearing support platform is installed on the vertical drilling machine workbench, and interacts with the vertical drilling machine workbench through guide rails. Slidingly connected, and the axis of the cam bearing platform is perpendicular to the horizontal plane. The cam bearing platform includes a bearing column, a positioning platform, a positioning fixture, a turntable mechanism, an in-position sensor and an auxi...

Problems solved by technology

[0004] The process of drilling deep holes also includes manual drilling process and deep hole drilling process. Manual drilling process is a process completed on a lathe with manual manual operation. The production efficiency of manual process is low. In order to meet the production capacity demand, often invest There is a lot of manpower, the labor intensity of workers is relatively high, and the stability of product quality is poor. The deep hole drilling process is processed by deep hole drilling machine tools. Tooling and gun drilling costs are high, leading to higher machining costs
