Abstract

The invention relates to an automatic machine tool for processing a pin hole of main angle steel of a middle section of a tower crane, which is characterized by comprising a machine tool body, a material part conveyor belt, a positioning die carrier, a positioning tensioning device, a plurality of power head devices and a control unit; wherein the machine tool body is a strip-shaped cuboid which is provided with a through groove in the longitudinal direction; the material part conveyor belt is arranged in the groove along the groove and extends to the outer part of the groove; the positioningdie carrier comprises a right-angle positioning template arranged above the groove and a positioning end plate fixed at the end part of the right-angle positioning template; the right-angle positioning template is fixed on the machine tool body, wherein the right-angle top part of the right-angle positioning template is upward, and the opening of the groove in the same vertical plane is covered by a right-angle ridge and the longitudinal centerline of the groove; the positioning tensioning device comprises a material part vertical jacking mechanism and a material part horizontal jacking mechanism; and the plurality of power head devices correspond to the machining hole of the right-angle positioning template and are respectively arranged at the two sides of the machine tool body in a reciprocating motion manner and in a way that a power head axial line is vertical to the template surface of the right-angle positioning template. The automatic machine tool has the advantages of high working efficiency and high quality, and the human and material resources are saved.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to an automatic machine tool for processing the steel pin hole of the central section of the tower crane. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites. It forms an iron tower by connecting sections to the ground, and is used to lift construction materials such as steel bars, wooden corrugations, and scaffolding pipes. The main steel of the middle section of the tower crane is an important part of the tower crane as a connecting piece. At present, the main steel of the middle section is generally provided with multiple sets of pin holes for installation, which are respectively arranged on two right-angled surfaces. figure 1 It shows the main steel 90 of the middle section of the tower crane typically used at present, which is provided with 4 groups of holes. On the two right-angled surfaces near one end of the main ste...
