Description

Multipurpose quick clamp

Technical Field

The utility model belongs to the technical field of instrument receiving arrangement technique and specifically relates to a multipurpose is pressed from both sides soon.

Background

By a machine tool is meant a device with one or more drive motors and possibly one or more transmission mechanisms. The drive means of the tool machine refers to one or more members for applying a torque to the tool, i.e. typically a drive shaft, a drive spindle (antitriebspindel), etc.

Manually guided power tools have a carrier, in particular a handle or the like, with which the power tool can be carried and guided together with the tool fastened thereto by the operating force. Usually, manually guided machine tools are equipped with an electric drive motor, but other types of construction are also known, such as hydraulic, pneumatic or muscle-powered machine tools.

From the prior art, numerous tool machines are known which are designed for use with tool arrangements having a rotary or rotationally oscillating drive. Such tool devices are, for example, drills, grinding and cutting disks, circular saws and the like. These tool arrangements can be fastened to the output of the machine tool by means of their drive and can be exchanged. Depending on the application, the tool arrangement and the machine tool, the output drive moves at a rotational speed of approximately 2 rpm, which in the extreme case can also be rotated at a significantly higher rotational speed. During operation, the tool arrangement exerts a more or less high pressure in contact with the workpiece or workpiece group, and then performs a corresponding machining process on the workpiece. The tool machines are often used in a versatile manner, i.e. for example sawing, grinding, scraping, glazing, etc., where glazing in the present invention means in particular removing a glass panel from a vehicle body, preferably cutting a strip of adhesive (klebereaup) on such a glass panel, which is also referred to herein by the person skilled in the art as glass removal, etc.

In the field of use, for example during grinding, different grinding tools must be driven at short intervals, which determines the need for frequent tool changes in many fields of use. The time that must be spent to change the tool arrangement directly affects the productivity that can be achieved with the tool machine. It is furthermore of great importance that the machine tool is capable of receiving the tool arrangement particularly safely, since a tool arrangement which is not received accurately results in a shortened service life of the tool arrangement in terms of its positioning relative to the machine tool, and a tool arrangement which is not received safely also poses a great potential risk, in particular for the machine operator.
