Abstract
An expendable jaw combination for use in connection with a chuck for a lathe, milling machine, or the like to hold work stock. A receiver member is attached to the chuck, and an engagement member is provided in an elongated recess in the receiver member for engaging the stock. The receiver member is preferably constructed of tool material, such as tool steel, while the engagement member may be made of a lower cost material which is easier to work, such as mild steel. After the engagement member is used one or more times, it may be reworked or expended. Locking means are provided for securing the engagement member to the receiver member during use.
Claims27
A jaw system for use in connection with a chuck for receiving stock to be worked, the jaw system comprising:
- a receiver member for attachment to the chuck, said receiver member defining a longitudinally extending recess and a longitudinally extending slot within said recess;
- an engagement member for engaging the stock, said engagement member being adjacent to said receiver member and carried in said recess of said receiver member;
- and
- at least one locking member for selectively fixing said engagement member to said receiver member.
A jaw system for use in connection with a chuck for receiving stock to be worked, the jaw system comprising:
- a receiver member for attachment to the chuck, said receiver member defining a longitudinally extending recess;
- an engagement member for engaging the stock, said engagement member being carried in said recess of said receiver member;
- at least one locking member for selectively fixing said engagement member to said receiver member;
- and
- said receiver member including at least one adjustment screw for selectively moving said engagement member longitudinally within said recess of said receiver member, and wherein said adjustment screw includes an enlarged head portion having a drive profile at one end thereof and a drive profile at the other end thereof.
A jaw system for use in connection with a chuck for receiving stock to be worked, the jaw system comprising:
- a receiver member for attachment to the chuck, said receiver member defining a longitudinally extending recess;
- an engagement member for engaging the stock, said engagement member being carried in said recess of said receiver member;
- at least one locking member for selectively fixing said engagement member to said receiver member;
- and
- said receiver member including at least one adjustment screw for selectively moving said engagement member longitudinally within said recess of said receiver member, and wherein said adjustment screw includes at one end thereof an enlarged head portion having an internal hexagonal drive profile and an internal hexagonal drive profile at the other end thereof.
A jaw system for use in connection with a chuck for receiving stock to be worked, the jaw system comprising:
- a receiver member for attachment to the chuck, said receiver member defining a longitudinally extending recess, said receiver member defining side walls adjacent said recess and said recess defining a floor portion, and wherein said floor portion extends outwardly beyond said side walls;
- an engagement member for engaging the stock, said engagement member being adjacent to said receiver member and carried in said recess of said receiver member;
- at least one locking member for selectively fixing said engagement member to said receiver member;
- and
- said recess of said receiving member defining an elongated slot for receipt of said locking member and for allowing selective longitudinal movement of said engagement member with respect to said locking member.
A clamping system for use in connection with a device for machining stock, the clamping system comprising:
- a chuck defining a stock passage for receiving stock to be machined, said chuck having at least one jaw movable towards and away from said stock passage;
- a receiver member for attachment to at least one of said jaws of said chuck, said receiver member defining a longitudinally extending recess and a longitudinally extending slot within said recess;
- an engagement member for engaging the stock, said engagement member being adjacent to said receiver member and carried in said recess of said receiver member;
- and
- at least one locking member for selectively fixing said engagement member to said receiver member.
A method of holding stock on a device during machining of the stock, the method comprising:
- providing a chuck defining a stock passage for receiving stock to be machined, said chuck having at least one jaw movable towards and away from said stock passage;
- inserting the stock in said passage;
- providing a receiver member, said receiver member defining a longitudinally extending recess and a longitudinally extending slot;
- attaching said receiver member to said at least one jaw of said chuck;
- providing an engagement member for engaging the stock;
- inserting said engagement member in said recess of said receiver member such that said engagement member is adjacent to said receiver member;
- providing at least one locking member;
- and
- selectively fixing said engagement member to said receiver member with said locking member.
