Embodiment Construction

[0009] exist figure 1 in perspective and in figure 2 The device shown in cross-section in is used to clamp the tool 1 in the tool holder 3 by means of a clamping nut 2 and a collet (not shown). For clarity, figure 1 The device is shown without a housing.

[0010] The diameter of the clamping ring 4 corresponds to the outer diameter of the flange of the tool holder, and is provided with a quick clamp 5 for quickly clamping and releasing the tool holder. Clamping ring 4 is rigidly connected via cylindrical sleeve 6 to lever 7 . The end of the lever bears against a pressure gauge 8 which is hydraulically connected to a display device 9 . The display unit is calibrated according to the torque applied to the clamping nut.

[0011] The functional components of the device are arranged in a housing 10 which is connected to a base plate 11 .

[0012] With the device according to the invention, any tool can be used to carry out the tightening of the clamping nut. No torque wrenc...

Abstract

The invention relates to a clamping device for clamping a tool in a tool holder by means of a collet and a clamping nut, said clamping device being provided with means for clamping the tool holder andfor detecting and displaying a torque exerted on the clamping nut.

Description

technical field [0001] The invention relates to a clamping system according to the preamble of claim 1 . Background technique [0002] When the tool is clamped in the tool holder by means of the collet, the conical collet is pressed into the receiving cone of the collet receiver with the clamping nut, whereby part of the collet is pressed against the tool shank . In this way, the tool is held in a form-fitting manner. [0003] The axial force used to compress the collet is directly dependent on the torque applied to the clamping nut. This torque should be kept within a narrow tolerance range. When the torque is too low, the form-fit between collet and tool will be too small and the tool may slip. When the torque is too high, damage to the clamp nut and tool receiver may occur. Additionally, the clamping nut and tool receiver may deform, which compromises the concentricity of the tool. Therefore, a torque wrench should be used for clamping. However in practice this is ...
