a combination tool

Abstract

A combined tool, comprising: a tool bar, a drill bit is installed on the top surface of the tool bar, and a first boring tool, a countersinking tool and a second boring tool are installed on the side; a driving assembly includes a guide rail, a driving screw rod, and a driving screw rod The nut is connected and slidably connected to the guide block on the guide rail, the star wheel synchronously connected to one end of the driving screw rod, and the driving rod. On the bedside box, the other end forms a toggle end that stirs the star teeth of the starwheel to make the starwheel rotate when the starwheel rotates to the lever. A rotating positioning pin; a milling cutter is installed on the end face of the guide block. Using the above-mentioned combined tool, the workpiece only needs to be clamped once, and rotated to the position to be processed, which can complete the four-sided drilling, boring, countersinking and milling of complex parts. The centralized process eliminates the installation error caused by the scattered process, improves the machining accuracy of the workpiece, and reduces the processing cost.

Description

technical field [0001] The invention relates to the field of machining cutters, in particular to a combined cutter. Background technique [0002] figure 1 , 2 It is the steering knuckle housing of the front axle of the automobile. Its structure is relatively complicated, and there are many holes and planes that need to be processed. At present, for this kind of workpiece with inner space and complicated processing process, it is usually processed by a machining center. However, the machining center The equipment cost and operating cost are relatively high, and it is difficult to be popularized. [0003] In addition, the dispersion process can also be used to process the above figure 1 , 2 For the workpiece shown, each tool completes the drilling, boring, countersinking, milling and other processing of different holes and surfaces. Although this processing process can be processed by traditional low-cost machine tools, each process needs to be carried out. Once the workp...

[0002] figure 1 , 2 It is the steering knuckle housing of the front axle of the automobile. Its structure is relatively complicated, and there are many holes and planes that need to be processed. At present, for this kind of workpiece with inner space and complicated processing process, it is usually processed by a machining center. However, the machining center The equipment cost and operating cost are relatively high, and it is difficult to be popularized

[0003] In addition, the dispersion process can also be used to process the above figure 1 , 2 For the workpiece shown, each tool completes the drilling, boring, countersinking, milling and other processing of different holes and surfaces. Although this processing process can be processed by traditional low-cost machine tools, each process needs to be carried out. Once the workpiece is clamped, the cumulative installation error of the workpiece clamping will be large, which will affect the accuracy of the workpiece
