Cam drilling tool suitable for multi-aperture cams

Abstract

The invention is a cam drilling tool suitable for multi-aperture cams. The cam drilling tool comprises a bottom plate, a vertical support plate is fixedly arranged on one side of the top of the bottomplate, a cam shaft hole support device capable of adjusting the supporting aperture is fixedly arranged at the middle portion of one side of the vertical support plate, one side of the vertical support plate is provided with a handle used for adjusting the supporting radius of the camshaft hole supporting device, a plurality of support bolts are horizontally arranged on the vertical support plate, and a cam locking device is arranged on the side wall of the side, far away from the vertical support plate, of the bottom plate; and a horizontal support plate is fixedly arranged on the top of thevertical support plate, and the horizontal support plate is provided with a drill positioning hole facilitating drilling in a vertically-penetrating manner. The camshaft hole support device can accurately position and support the cams. By means of the manner, the drilling efficiency is improved on the premise of ensuring drilling accuracy, one set of tool is suitable for the cams with multiple apertures, the need of making multiple sets of positioning tools for the cams with the different apertures is avoided, unnecessary resource consumption is avoided, resources are saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of machining tooling, in particular to a cam drilling tool suitable for multi-aperture cams. Background technique [0002] The cam is generally equipped with a fixed hole for easy connection with the main shaft. In the drilling method of these fixed holes, the traditional method is to use manual measurement and drilling. This method requires measurement for each drilling, resulting in The efficiency is low, and the drilling accuracy is greatly affected by the technical level and experience of the workers, and the product quality is difficult to guarantee; some workers use the tool positioning drilling method. Although this method improves the drilling efficiency and accuracy, it needs to be specific The production of multiple sets of positioning tooling for the unique cam consumes a lot of resources. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and prov...
