US 4,051,584 A · Cutting tool assembly

Abstract

A cutting tool assembly which includes a tool fixture support and a clamping strap mounted on a tool holder. The tool fixture support is provided with at least one groove or bore for receiving at least one pin element on the clamping strap whereby the lateral centering of the tool fixture support and the clamping strap is effected. The clamping strap includes a vertically extending lug portion received in a channel provided in the tool fixture support which ensures the vertical alignment of the clamping strap with respect to the tool fixture support. The tool fixture support and clamping strap are mounted on either a rigid tool holder provided with at least one longitudinally extending channel for receiving at least one connecting tongue of the tool fixture support or are mounted on a resilient tool holder. The construction of the tool fixture support and clamping strap result in a construction for enabling the use of the tool assembly as either a right hand or left hand tool.

Summary780 words

#The present invention relates to a cutting tool, and more particularly to a cutting tool assembly for use on a rotating machine tool which assembly can be utilized as either a right hand or a left hand tool.

#Cutting tools are generally known which include a cutting tip made of a high speed steel, hardened steel or carbide metal and such conventional tools are designed in each case as either a right hand or a left hand tool depending on their use. In general the arrangements for clamping the cutting tip of the conventional tools have a wide clamping claw or clamping strap and, for this reason, the tool holders must be clamped or tensioned laterally or in front of the machine carriage or slide. However, to effect the clamping of the cutting tip in a flawless manner and without lateral deviation, complicated centering operations must be carried out at the clamping strap with narrow tolerances since any lateral error of the clamping finger or claw increases as related to the strap length to strap width ratio. Additionally, the conventional cutting tools are useable in most cases for only one machine size.

#The present invention is concerned with the task to provide a cutting tool construction which is structurally simple and suitable for universal utilization in machine tools while eliminating the aforementioned shortcomings of the prior art.

Brief description of the drawings26 figures

#These and further objects, features and advantages of the present invention will become more apparent from the following description when taken in connection with the accompanying drawing which shows, for the purposes of illustration only, several embodiments in accordance with the present invention, and wherein:

#FIG. 1 is a partial side view of a tool assembly in accordance with the present invention;

#FIG. 2 is a view taken in the direction of line A--A in FIG. 1;

Detailed description1,312 words

#Referring now to the drawing wherein like reference numerals are used throughout the various views to designate like parts, and more particularly, to FIG. 1, according to this Figure, a cutting tool assembly generally designated by the reference numeral 1 includes a tool holding fixture 10, tool clamping strap 3, tool fixture support 4, and a cutting tool or tip 13. The tool holding fixture 10 is essentially of a rectangular configuration (FIGS. 11, 11a) and may be produced by a simple mechanical machining step. The height and width of the holding fixture 10 may be varied in accordance with the configuration of the cutting machine with which it is utilized since the tool fixture support and clamping strap of the present invention are independent of the specific dimensions of the tool holder 10.

#The tool fixture support 4 is provided with grooves 6 along portions of at least one longitudinal side thereof. One of the grooves 6 is disposed immediately adjacent the cutting tip 13 for receiving and accurately and precisely guiding the tip.

#As shown in FIG. 2, the holding fixture 10 is provided with a longitudinally extending recess or channel 15 which receives a connecting tongue 12 provided on the tool fixture support 4. The groove 15 is disposed in the holding fixture 10 and extends equally on both sides of a horizontally extending plane 11 thereby assuring accurate alignment of the tool fixture support 4 and the cutting tip 13. To facilitate the mounting of the tool fixture support 4 so as to be readily adaptable for a right hand or left hand mode of operation, an additional recess or channel 15a may be provided in the tool holding fixture 10.
