Abstract
An adjustable fork gauge including a main body having a slide on which a first, fixed jaw is slidably and adjustably mounted and formed from a block having an anvil with a plane face integral with said block; a second, spring clamping jaw adapted to press a plane or cylindrical portion of a part to be measured on the anvil of the fixed jaw; a feeler rod for the part to be measured including a contact adapted to emerge from the clamping jaw and displaceably mounted for translation in a bearing of the body such tha the axis of said feeler rod is perpendicular to the plane of the anvil of the fixed jaw; and a measuring or indicating transducer coupled to the body and having a movable element connected to the feeler rod.
Claims10
An adjustable fork gauge comprising a main body;
- said body having a slide on which a fixed jaw is slidably and adjustably mounted, said fixed jaw being formed from a slide block having an anvil with a plane face integral with said slide block;
- a spring clamping jaw means mounted in opposition to said anvil for pressing a portion of a part to be measured towards the anvil of the fixed jaws;
- a feeler rod for said part to be measured, said feeler rod being displaceably mounted in a bearing of the clamping jaw means whereby the axis of said feeler rod is perpendicular to the plane of the anvil of the fixed jaw;
- a contact means mounted on said feeler rod to emerge from said clamping jaw means for contacting said part to be measured;
- and an indicating transducer coupled to the body and having a movable element operatively connected to the feeler rod;
- wherein said fixed jaw has a lateral abutment means for supporting the said part to be measured and said abutment means has a plane face which is perpendicular to the plane face of the anvil of the fixed jaw;
- wherein said slide of the body and said slide block forming said fixed jaw are inclined at the same acute angle (A) with respect to the axis of the feeler rod and said acute angle is inscribed in a plane perpendicular to the two planes constituted by the plane face of the anvil and the plane face of the lateral abutment means of the fixed jaw;
- wherein said clamping jaw means includes a floating shoe at its end in opposition to said anvil, said floating shoe having a cylindrical bearing surface whose generatricies are, during working, parallel at least to the plane of the lateral abutment means of the fixed jaw;
- wherein said floating shoe is pivotally mounted on a linear pivot disposed between said end of the clamping jaw means and the floating shoe and the pivotal axis of which is perpendicular to the plane face of the lateral abutment means of the fixed jaw;
- and wherein said floating shoe is connected to the said end of the clamping jaw means by at least one retaining member.
