Abstract
A locking system for securing tools on an arbor. The locking system has a collar attached to the arbor, with the collar spaced from the tooling. A nut is placed over the collar and positioned next to the tools. The nut is then rotated to secure the nut between the collar and the tools.
Description
- Tooling on roll forming and slitter arbors has traditionally been held onto the arbor by using a threaded nut on the end of the arbor that receives the tooling. The threaded nut must have mating threads that are machined into the end of each arbor. These threads on the arbor are subject to damage as tooling is loaded onto the arbor, the nut is threaded upon the arbor or removed from the arbor, or just by being exposed in the work place. Damaged threads can require costly maintenance to restore to a working condition. Therefore, there is a need for a more robust system to hold tooling on arbors that does not require threads.
- The present invention is an arbor tool locking system. The system uses a flanged nut that rotatably engages a keyed collar on the arbor. The collar forms a part of the arbor and is spaced from that part of the arbor that carries the tooling. The nut is slid over the collar and partially rotated to cause the nut flanges to be positioned between the collar and the tooling upon the arbor with the nut compressed against the tooling.
- An object of the invention is to provide a locking mechanism to hold tooling on arbors without the use of screw threads.
- Another object of the invention is to provide a locking mechanism for tooling of a roll former and slitter which can be economically maintained and of rapid operation.
- Still other objects of the invention will become apparent upon reading the following description.
- A preferred embodiment of this invention has been chosen wherein:
-
FIG. 1 is a perspective view of a slitter with tooling stacked and locked on the arbors; -
FIG. 2 is a fragmentary side view of an arbor end in partial sectional form; -
FIG. 3 is a perspective exploded view of the slitter tool lock; -
FIG. 3A is a perspective view of the nut of the tool lock shown in assembled form; -
FIG. 4 is a view of the end of an arbor with the nut installed in its released position; and -
FIG. 5 is a view of the end of an arbor with the nut installed in its locked position rotated 45 degrees from the position shown inFIG. 4 . - The tool locking system of this invention includes a
nut 10 and a collar 11 forming a component ofarbor 12.Arbor 12 is shown as forming a part of aslitter 5. Thenut 10 has equally radially spaced flanges orbosses 14 that protrude toward the inside of the nut as shown inFIG. 3A .Flanges 14 are inwardly spaced fromouter edge face 15 of the nut.Nut 10 has anannular groove 18 formed in its inner edge face 17 as shown inFIG. 3A . Theannular groove 18 in the nut receives apressure ring 22. Abore 23 extends innut 10 intogroove 18 behindring 22. Agrease zerk fitting 40 is located inbore 23 atface 15.Pressure ring 22 forms what is also known in the trade as a Jetnut. Aball check valve 44 is also located atface 15 in abore 25 intogroove 18. Collar 11 is attached to or forms an intregal part ofarbor 12 and includes a plurality of equal radially spacedcoplanar flanges 16 spaced just slightly more than the thickness ofnut flanges 14 fromshoulder 19 of thearbor 12. - The outer diameter of collar 11 at the
ends 21 of theflanges 16 is less than themajor diameter 26 of the arbor to allowtooling 30, in the form of cutters and spacers, to pass over theflanges 16 at the end of thearbor 12. This outer diameter of collar 11 is also less than the inner diameter of nutinner surface 13. -
Tooling 30 is stacked on thearbors 12, as shown inFIG. 1 , until the arbors are full from theinner shoulder 34 to theouter shoulder 19 of the arbor.FIG. 2 shows a sectional view of afull arbor 12 near theopen end 36 of the arbor. Once thearbor 12 is full oftooling 30, thenut 10 is inserted upon theopen end 36 of the arbor with theflanges 14 on thenut 10 lining up with the spaces 38 between theflanges 16 on thearbor 12. Thenut 10 is pushed onto the arbor end untilpressure ring 22 preferably abutsarbor shoulder 19. This position is shown inFIG. 4 and is the nut's unlocked position. The depth offlanges 14 are such that the flanges clear theroot face 29 of collar 11 betweenflanges 16. Thenut 10 is then turned 45 degrees to its locked position, as show inFIG. 5 , so that theflanges 14 of the nut are then between theflanges 16 of the collar andshoulder 19 of thearbor 12. Ahole 42 is provided in the side of thenut 10 in which a rod or spanner wrench may be inserted to assist in turning thenut 10. In the 45 degree rotated position shown inFIG. 5 , a grease gun is then used to force grease intogroove 18 of the nut through fitting 40. The pressurized grease causes thepressure ring 22 to forcefully press against thetooling 30, thereby securing thetooling 30 in place on the arbor and locking thenut 10 against collar 11. To unlock thenut 10,check valve 44 is open to release the pressure upon the grease inchamber 23 which causespressure ring 22 to no longer forcefully push against thetooling 30. This allowsnut 10 to be turned into its released position, as shown inFIG. 4 , where it can be removed to free thetooling 40 for replacement. - The above described invention is not to be limited to the details given but may be modified within the scope of the following claims.
