Abstract
Abstract An arrangement for the control of a boring tool and a machining tool in a direction distinct from the axial direction, the tools being mounted on a tool holder integral with a boring head and formed of a first tool holder part and a second tool holder part movable relative to the first tool holder part, wherein a single rod is movably disposed in one of the tool holder parts for movement in a first direction and in a second reversing direction thereof and the control rod is connected to the boring tool and the machining tool to provide in succession, upon movement of the control rod in the first direction, adjustment of the position of the boring tool to compensate for deviations in the bore and retraction of the machining tool in a direction distinct from the axial direction, and upon movement of the control rod in the reverse direction, retraction of the boring tool and advancing motion of the machining tool in a reverse direction of the direction distinct from the axial direction. The machining tool may be performing dressing, chamfering or grooving operations.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
187 words
An arrangement for the control of a boring tool and a machining tool in a direction distinct from the axial direction, said tools being mounted on a tool holder integral with a boring head and formed of a first tool holder and a second tool holder part movable relative to said first tool holder part, comprising: a single control rod movably disposed in at least one of said tool holder parts for mOvement in a first direction and in a second direction being the reverse of said movement in said first direction; and means connecting said control rod to said boring tool and to said machining tool being operable to provide in succession, upon movement of said control rod in said first direction, adjustment of the position of said boring tool to compensate for deviations in the bore and retraction of said machining tool in a direction distinct from the axial direction, and upon movement of said control rod in said second direction, retraction of said boring tool and advancing motion of said machining tool in a reverse direction of said direction distinct from the axial direction.
Claim 2
Dependent Claim
187 words
An arrangement for the control of a boring tool and a machining tool in a direction distinct from the axial direction, said tools being mounted on a tool holder integral with a boring head and formed of a first tool holder and a second tool holder part movable relative to said first tool holder part, comprising: a single control rod movably disposed in at least one of said tool holder parts for mOvement in a first direction and in a second direction being the reverse of said movement in said first direction; and means connecting said control rod to said boring tool and to said machining tool being operable to provide in succession, upon movement of said control rod in said first direction, adjustment of the position of said boring tool to compensate for deviations in the bore and retraction of said machining tool in a direction distinct from the axial direction, and upon movement of said control rod in said second direction, retraction of said boring tool and advancing motion of said machining tool in a reverse direction of said direction distinct from the axial direction.
Claim 3
Dependent Claim
70 words
An arrangement for control of a boring tool and a machining tool according to claim 1, wherein said means connecting said control rod to said boring tool and said machining tool comprises: an inclined surface on said control rod; a first push rod slidably disposed in said first tool holder part and operatively engaging said second tool holder part for effecting motion thereof relative to said first tool holder part.
Claim 4
Dependent Claim
75 words
An arrangement for control of a boring tool and a machining tool according to claim 2, wherein said means connecting said control rod to said boring tool and said machining tool further comprises: a second push rod slidably disposed in said first tool holder part and resting against said movable second tool holder part of the tool holder through an adjustable stop therein, said second push rod being operatively engaged with said first push rod.
Claim 5
Dependent Claim
131 words
An arrangement for control of a boring tool and a machining tool according to claim 2, wherein said means connecting said control rod to said boring tool and said machining tool further comprises: a second push rod slidably disposed in said first tool holder part and resting against a stop adjustably mounted in said second tool holder part and extending between said second tool holder part and said first tool holder part; a sleeve disposed about said stop being secured to said first tool holder part and extending therefrom in the direction of said second tool holder part for contacting the same and maintaining a predetermined gap therebetween; and an elastic means interposed between said stop and said sleeve for urging said stop in the direction of said second push rod.
Claim 6
Dependent Claim
125 words
A control arrangement for control of a boring tool and a machining tool according to claim 2, wherein said means connecting said control rod to said boring tool and said machining tool comprises: a holder for said machining tool being slidable within said second tool holder part; a lever composed of ball joints disposed at its ends and intermediate thereof, one of said end ball joints being seated within an opening in one end of said control rod, another of said end ball joints being seated within an opening in said machining tool holder, and the intermediate ball joint being seated in a socket in said second tool holder part; and elastic means urging said ball joint in said control rod to move outwardly thereform.
Claim 7
Dependent Claim
188 words
A control arrangement for control of a boring tool and a machining tool according to claim 5, further comprising: said control rod having an axial bore in one end; a pin slidably disposed in said axial bore of said control rod; means resiliently urging said pin to move outwardly of said axial bore of said control rod; said pin being selectively stoppable at the other end against an adjustable bolt stop mounted in said second tool holder part of the tool holder and against a peg fastened to the end of said control rod; said pin having a circumferentially disposed groove which engages a ball held in a hole in said control rod being slidable therewith; a sleeve in which said control rod is slidably received, said sleeve having a groove on its inner periphery adjacent one end thereof; said ball slidable with said control rod and said pin being engagable with sAid groove of said sleeve; and said opening in said one end of said control rod for receiving a ball joint of said lever being an opening in said pin slidably disposed in said control rod.
