Definitions

  • aspects of the present disclosure relate generally to tooling bases that are used to attach a variety of tooling fixtures that would hold a work piece to a work surface for machining, and, more specifically, to embodiments of tooling bases that allow the fixtures to be pneumatically attached and removed from the tooling base, all while maintaining registration accuracy.
  • a tooling fixture is used to hold a work piece during intricate machining such as 5-axis machining.
  • the fixture system requires that the work piece be held securely and precisely and provides access to a machine tool to all facets of the work piece.
  • tooling fixtures are mounted directly to the bed or work surface of the milling machine.
  • it is necessary to process a part on different machines requiring the part to be removed from one machine, worked or processed elsewhere and returned to the first machine. In certain circumstances, removal of the tooling fixture may be difficult to de-couple from the tooling base.
  • the present disclosure is accordingly directed to an improved tooling base having ejector pins that may aid in the removal of the tooling fixture.
  • the background description provided herein is for the purpose of generally presenting the context of the disclosure. Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art, or suggestions of the prior art, by inclusion in this section.
  • a tooling base with pneumatically-activated ejector components for detaching a tooling fixture is disclosed.

  • FIG. 4 depicts details of an exemplary embodiment of the internal components of the tooling base, including the ejector pins, when the tooling base is in an unclamped state, according to various aspects of the present disclosure.
  • FIG. 5 depicts a magnified view of an ejector pin when the tooling base is in an unclamped state, according to various aspects of the present disclosure.
  • FIG. 6 depicts a top perspective view of another exemplary tooling base in a clamped state in which a tooling fixture is secured via alignment studs, according to various aspects of the present disclosure.
  • FIG. 7 depicts a top perspective view of another exemplary tooling base in an unclamped state with ejector pins deployed and the tooling fixture unsecured, according to various aspects of the present disclosure.
  • FIG. 8 depicts a magnified view of a top surface of the exemplary tooling base in FIG. 7, according to various aspects of the present disclosure.
  • FIG. 9 depicts details of an exemplary embodiment of the internal components of another tooling base, including the ejector pins, when the tooling base is in a clamped state, according to various aspects of the present disclosure.
  • FIG. 10 depicts details of an exemplary embodiment of the internal components of another tooling base, including the ejector pins, when the tooling base is in an unclamped state, according to various aspects of the present disclosure.
  • FIG. 1 1 depicts details of an exemplary working configuration of another tooling base, according to various aspects of the present disclosure.
  • exemplary is used herein in the sense of “example,” rather than “ideal.” It should be noted that all numeric values disclosed or claimed herein (including all disclosed values, limits, and ranges) may have a variation of +/- 10% (unless a different variation is specified) from the disclosed numeric value. Moreover, in the claims, values, limits, and/or ranges mean the value, limit, and/or range +/-10%.
  • a tooling base is a system that attaches to a milling or other machining device and is precisely registered to that device. A vise or other fixture is then attached to the tooling base, again with precise registration to the tooling base, and therefore to the machining device. The tooling base further provides means to detach and re-attach a tooling fixture while maintaining precise registration.
  • Tooling bases are known, such as those described in U.S. Pat. No. 9,902,033; U.S. Pat. No. 8,708,323; U.S. Pat. No. 10,603,750; U.S. Pat. Pub. No. 2007/0187909; German Pat. No. DE10117485B4; International Pat. Pub. No.
  • particulate material resultant from the machining process may populate portions of the precision zone (i.e., the area of attachment where the alignment studs of the tooling fixture are inserted into the registration holes of the tooling base). The presence of these particulates may impede proper registration of subsequent tooling fixture attachment.
  • a tooling base 101 is shown in a clamped state.
  • the tooling base 101 may be registered to the milling or other processing machine using tooling pins (not shown) and bolts (not shown), as are known in the art.
  • the tooling base 101 in the clamped state secures alignment studs 102 of a tooling fixture (not shown) inside registration holes 103 of the tooling base 101 .
  • This securement may be facilitated via actuation of an internal clamp (details not shown) that operates clamping fixtures to clamp the alignment studs 102 into the registration holes 103.
  • ejector components of the tooling base 101 may remain in a substantially withdrawn state inside ejector holes
  • a top surface 106a of each precision zone 106 may be slightly raised over a top surface 107 of the tooling base 101 . In this configuration, the tops of the ejector pins 104 may remain under or flush with the top surface 106a of each precision zone 106.
  • Such a configuration is not limiting and other embodiments may exist (e.g., in which tops of the ejector pins 104 remain under or flush with the top surface 107 of the tooling base 101 , as further described herein and illustrated in FIGS. 6 - 10.
  • the raised ejector pins 104 may correspondingly push the tooling fixture up and away from the tooling base 101 , thereby aiding in the disengagement process and enabling easier removal of the tooling fixture by a machining robot (not pictured).
  • each of the ejector pins 104 may contain an upper port hole 108 that is oriented toward its corresponding alignment stud 102.
  • a chosen material or substance e.g., air, fluid, etc.
  • each of the ejector pins 104 may be spring loaded and may be coupled to a spring 112 located on the side of the ejector pin 104 remaining situated within the housing of the tooling base 101 .
  • FIG. 3 is illustrated as having a gap 116 between the ejector pins 104 and the piston 113, such a configuration is not limiting. More particularly, other embodiments may exist (not explicitly illustrated here) in which the ejector pins and the piston are arranged differently with respect to each other than in FIG. 3. For example, in an embodiment, the ejector pins 104 may be directly mounted to the piston 113 and may rise and fall in unison with the piston operation.
  • one application of compressed air to the tooling base 101 may be sufficient to both decouple the tooling fixture from the tooling base 101 and also raise the ejector pins 104 up and out of the top surface 107 of the tooling base 101.
  • compressed air supplied to the tooling base 101 for automated operation is typically supplied by computer actuated valves, as are known in the art.
  • a computer system may be configured to supply the compressed air substantially immediately prior to the removal of the tooling fixture by a machining robot. Additionally or alternatively, the computer system may be configured to supply the compressed air only upon determination that the tooling fixture is secured by the robot. Additionally or alternatively, the computer system may be configured to supply the compressed air upon receipt of a user command at the computer system.
