Embodiment Construction

[0033] exist figure 1 shows a tool of a well-known tube end processing machine in its basic structure which can be reciprocated in the longitudinal or Z direction (as indicated by the arrows) by means of a sliding guide 1 on a linear guide of the machine tool Slider 2. A slide 4 and a headstock 5 are arranged on the slide housing 3 . The motor 4 transmits its drive power via the drive shaft 6 with the pinion 7 and the intermediate gear 8 to the outer ring gear 9 of the hollow main shaft 10 which is guided through the headstock 5 , arranged at the front side of the headstock 6 The tool head 11 rotates with the spindle 10. exist figure 2 The aforementioned drive train (including the tool head 11 ) is shown without the headstock.

[0034] exist image 3 The tool head 11 shown schematically in has three sliding blocks (with the tool 13 carried by them) that are configured in its base body 12 and cooperate in pairs, namely the sliding block pairs 14A, 14B and 15A , 15B and 1...

Abstract

The invention relates to a machine for machining the ends of pipes which, for control purposes, is assigned at least one computer unit and in the case of which the tools (13) are arranged displaceably such that they can engage radially in relation to the pipe in a tool head (11) which is driven by a motor (4) via a main spindle (10) guided through a headstock (6), the tool head rotating coaxially about the fixedly clamped pipe end, wherein the tools are arranged in tool holders in the form of slides (14A, 14B; 15A, 15B; 16A, 16B) and adjacent slides together mesh with a toothed wheel which is formed with weight compensation. According to the invention, the tool head (11) is formed with integrated advance motors (17) assigned to the slides (14A, 14B; 15A, 15B; 16A, 16B), and each slide is assigned a measuring device (24).

Description

technical field [0001] The invention relates to a pipe end processing machine (Rohrendenbearbeitungsmaschine), which for control is associated with at least one computer unit and in which the tool is movably arranged in a radially adjustable manner with respect to the pipe on ) in a tool head (Werkzeugkopf) whose spindle is driven by a drive motor, the tool head rotates coaxially around a fixedly clamped pipe end, wherein the tool is arranged in a tool holder configured as a slide and the adjacent slides jointly Meshes with gears constructed with counterweights (Gewichtsausgleich). Background technique [0002] A machine tool with such a tool head for machining pipe ends, in particular for cutting threaded joints, is known from DE 44 38 818 A1. Pipe threads are typically produced in a single pass of the tool over the pipe end, where the movement of the tool is numerically controlled. In these machines, the actual tool head (the tool in which the thread of the pipe is produ...
