Taper hole drilling machine tool for steering knuckle arm

Abstract

The invention relates to the field of mechanical processing, and discloses a taper hole drilling machine tool for steering knuckle arms, which includes a workbench, a tool driving device provided with the workbench, and a servo sliding table slidably connected to the workbench. The tool driving device includes an electric control box , column, spindle box, servo thrust motor, three spindles are connected to the spindle box for rotation, the axes of the spindles are on the same plane, and the spindles are respectively connected with drilling drills, rough reaming drills and fine reaming drills, and the servo sliding table is connected with a device clip assembly. The present invention has the following advantages and effects: by connecting the drilling bit, the rough reaming bit and the fine reaming bit to the three main shafts respectively, the drilling and reaming process is performed on the taper hole end, which improves the machining efficiency and machining accuracy, and reduces the burden on the operator. Technical dependence; the tensioning part pushes the tensioning sleeve to expand to tighten and position the bolt hole, which ensures that the steering knuckle arm can rotate, avoids the deformation of the steering knuckle arm, and improves the stability of the taper hole position.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a taper hole drilling machine tool for steering knuckle arms. Background technique [0002] The steering knuckle arm is the last power transmission part of the steering transmission device, and it is the part that finally realizes the steering, but how to connect the fan-shaped motion generated by the rocker arm of the steering gear to the left steering knuckle, so on the left steering knuckle The steering knuckle arm is added, and it is connected with the steering rocker arm through the steering trailing rod to realize the steering function. [0003] The steering trapezoidal arm is shown in Figure 7, including the connecting arm, the fixed end and the taper hole end. There are two bolt holes on the fixed end, and the taper hole end is provided with a taper hole. The taper hole end is processed on a traditional lathe. At the same time, it is necessary to drill the positioning ...

Problems solved by technology

[0003] The steering trapezoidal arm is shown in Figure 7, including the connecting arm, the fixed end and the taper hole end. There are two bolt holes on the fixed end, and the taper hole end is provided with a taper hole. The taper hole end is processed on a traditional lathe. At the same time, it is necessary to drill the positioning hole, rough reaming taper hole, and fine reaming taper hole on the end of the column hole in sequence. Since three different tools are used for the above-mentioned processing, the tool needs to be changed and re-positioned before the processing is completed. , highly dependent on the operator's technology, which reduces the processing quality and processing efficiency
