Definitions
- This invention relates to test frames, and more particularly to materials testing machines embodying such frames.
- Improved devices for imposing stress may be provided by using extruded members to partially enclose stressing members movable relative to the extruded members.
- a pair of extruded aluminum members open at transversely facing sides, with a stressing member extending through the opening in each extruded member and being mounted on drive screws and guide rods for movement driven by the former and guided by the latter, one such drive screw and one such guide rod extending within each of the extruded members and being enclosed by an extruded member in cooperation with an accordion blind, the extruded members being provided with T-slots for selectively mounting therein T-slides.
- FIG. 1 is a front elevation view, somewhat simplified, of the preferred embodiment.
- FIG. 2 is a side elevation view, again somewhat simplified, thereof.
- FIG. 3a, 3b, 3c are respectively a front elevation, side elevation, and plan view of a T-slide element of said embodiment.
- FIG. 4 is a sectional view, taken at 4--4 of FIG. 1 and enlarged.
- FIG. 5 is an end elevation view of the column show in cross-section in FIG. 4, and to the same scale as FIG. 4.
- FIG. 6 is a side elevation view corresponding otherwise to the view of FIG. 5.
- FIG. 1 there is shown a materials testing machine frame indicated generally at 10. It includes two extruded aluminum cover columns 12, 14, a top housing 16, a crosshead 18 with protruding finger 20, movable limit stops 22, 24, with respectively cooperating knobs 26, 28, a base housing indicated generally at 30, two slots 32 in each column, cooperating with slots in top housing 16 to provide therewith three continuous slots from base housing 30 to the top of top housing 16, and a fourth along column 12.
- Base housing 30 includes front lower portion 34 and front upper portion 36, integrally injection molded in a single plastic molding. Extending from upper portion 36 is control knob 38, and mounted on upper portion 36 are electronics components housing 40 and motor housing 42.
- a curved surface 50 Interposed between coplanar surfaces 36 is a curved surface 50 defined by moving a vertical line along an arc of a circle of large radius; curved surface 50 intersects a horizontal planar surface of lower portion 34 to provide a shelf.
- the slots 32 are T-shaped in cross-section.
- Slides 60 may be used in slots 32, in which they slidably fit. They may be introduced through the tops of the columns 12, 14 as desired. Bump 62 on springy arm 64 separated by slot 66 from body portion 68 is by arm 64 urged against a slot 32 with enough force to sustain a vertical position in the column or cover. Bumps 70 in cooperation with the aluminum of the cover helps with this function in the perpendicular direction. Hole 72 permits a fastener (not shown) with its head in hexagonal countersink 74 to engage, for example, an accessory desired to be carried in a slot 32. Element 60 is a unitary molding of glass-reinforced polycarbonate plastic.
- a guide rod (not shown) for crosshead 18 extends vertically from within base cover 30 to within top housing 16 in each cover 12, 14. Also extending vertically for the same extent, also within the housing 16, is a drive screw (also not shown) mounted to cooperate with crosshead 18 to drive it up and down.
- an accordion blind 80 is secured, by loop and hook fasteners as the one sold under the Trademark Velcro (not shown), to crosshead 18 at each end on the cross-head top, and at each end on the cross-head bottom, opposing ends being secured by hook and loop fasteners (not shown) to, respectively, the bottom of top member 16 and the top of housing 30.
- the guide rods and drive screws are thus fully enclosed, the accordion blinds (formed of nylon cloth with a rubbery impregnant) being adapted to open and close as needed.
- the extrusions 12, 14 include circular portions 90, 92 to cooperate with pins in top portion 16 in assembling and retaining the latter.
- a groove provides for adhering therein a scale with linear measurement indicia, and another groove provides for snapping thereinto a slidable indicator of position on the scale.
- Elongated bumps 100 are provided to enhance ornamental appearance, molded into the respective parts.
- the invention provides many advantages.
- the accordion blinds jointly with the extruded column covers provide complete enclosure of drive screws and guide rods.
- T-slides in T-slots may be made on T-slides in T-slots.
- testing accessories such as frame lights and protection shields may be so mounted.
- relief points for accessory cables may be so provided.
- the invention provides not only the above advantages, but is less expensive than the sheet metal cover devices above described, in part because of the integral nature of accordion blind guides and the accessory attachment means, in part because anodizing makes possible eliminating painting, and because of the construction generally.
