Abstract
A crimping tool has a housing, a driving shaft rotatably mounted in the housing and a driven shaft pivotally and rotatably mounted in the housing. The driving shaft and the driven shaft extend from the housing. The driven shaft is pivotally movable between an operative crimping position wherein the driven shaft extends in a spaced parallel relation with the driving shaft and operatively engages the driving shaft for driven rotation and an open ready position wherein the driven shaft is pivoted away from the driven shaft out of driving engagement therewith. A first driver operatively engages the driven shaft selectively effecting the pivotal movement. A second driver operatively engages the driving shaft selectively effecting the driving rotation.
Description
CItIIVIPING TOOL
held Of The Invention This invention relates to a crimping tool. In particular, this invention relates to a crimping tool far crimping a flange cover or weatherseal onto a door, trunk or ligftgate opening flange of a vehicle frame.
Background Of The Invention An automobile frame normally is manufactured using multiple inner and outer panels that are welded together leaving a flange around the perimeter of the various door, truck or liftgate openings. To install the flange cover or weatherseal on the flange, the side portions are crimped or pressed tightly together clamping against the flange retaining the cover or weatherseal thereon.
Various crimping tools are known which are used to crimp a flange cover or weatherseal onto a flange. United States Patent no. 5,875,670 discloses a typical crimping apparatus currently in use. However, there exists a need for an improved crimping tool which is smaller, less complicated, has less moving parts, and allows a tighter radius to be crimped than known crimping tools.
Summary Of The Invention In a broad aspect of the present invention, there is provided a crimping tool that has a housing, a driving shaft rotatably mounted in the housing and a driven shaft pivotally and rotatably mounted in the housing. The driving shaft and the driven shaft extend from the housing. The driven shaft is pivotally movable between an operative crimping position wherein the driven shaft extends in a spaced parallel relation with the driving shaft and operatively engages the driving shaft for driven rotation and an open ready position wherein the driven shaft is pivoted away from the driven shaft out of driving engagement therewith. A first driver operatively engages the driven shaft selectively effecting the pivotal movement. A second driver operatively engages the driving shaft selectively effecting the driving rotation.
The crimping tool closes upon a seal and travels therealong progressively closing the seal onto the flange.
Brief Description ~f The Drawings The invention will be better understood with reference to the drawings, in which:
Fig. 1 is a perspective view of a preferred ernbod:iment of a crimping tool of the present invention, showing a driving shaft and a driven shaft extending from a common housing;
Fig. 2 is a partial sectional view through the crimping tool of Fig. 1 in which the driving shaft and the driven shaft are shown in a closed operative crimping position; and Fig. 3 is a partial sectional view through the crimping tool of Fig. 1 in which the driving shaft and the driven shaft are shown in an open ready position.
Description Of The Invention The crimping tool 10 of the present invention is generally illustrated in Figure 1.
The crimping tool 10 comprises a housing 12. A pneumatic drive motor 14 is mounted to ~ the housing 12 and is operatively connected to driving shaft 16 that extends out of the cover 18 of housing 12 through circular aperture 20. Driven shaft 22 extends out of housing 12 through elongate slot 24. Driven shaft 22 is pivotally mounted to the housing by pin 26.
Shaped rollers 28, 30 are mounted on the distal ends of shafts 16, 22, respectively.
Preferably, rollers 28, 30 are made of stainless steel with a polished surface to prevent damage to the seal being crimped. Rollers 28, 30 can be sized according to the amount of crimping and the size of the seal to be crimped.
Air cylinder 32 is mounted to the housing 12 and operatively engages the driven shaft 22 to effect pivotal movement between an operative position wherein the shafts 16, 2S 22 are in a spaced parallel relation to each other and a ready position wherein shaft 22 is pivoted away from shaft 16.
Refernng to Figures 2 and 3, housing 12 defines an inner cavity 34. Cover 18 closes the cavity 34. Driving shaft 16 extends through the housing 12 and is journal mounted. Driving gear 36 is mounted along the shaft 16 and positioned within cavity 34.
Pneumatic motor 14 drivingly engages driving shaft 16. Pneumatic energization of motor I4 drivingly rotates shaft 16.
Driven shaft 22 is rotatably mounted to pivot housing 38. Pivot housing 38 is pivotally mounted internally of housing 12 by pin 26. Driven gear 40 is mounted on driven shaft 22 within cavity 34. Pneumatic cylinder 32 is mounted to the outside of housing 12. Cylinder 32 includes a ram 42 that extends into the housing 12 into cavity 34. The distal end of the ram 42 operatively connects to the pivot housing 38.
Preferably, cylinder 32 operates in bi-directionally providing positive movement to the pivot housing 38 in pivoting the driven shaft 22 between the open ready position (FIG. 3) and the closed operative position (FIG. 2).
Cylinder 32 and motor 14 are preferably connected to a common source of pneumatic pressure. Still preferable, a common trigger operates both the cylinder 32 and motor 14 according the preferred mode of operation as is described below.
Referring to Figure 2, when the crimping tool 10 is in the closed crimping and operative condition, the shafts 16, 22 extend generally parallel to each other. Gears 36 and 40 are in meshing engagement such that driving rotation of shaft 16 will cause driven rotation of shaft 22 in a rotation sense opposite to the rotation of shaft 16.
In operation, an open seal 44 is placed over a flange 46. The seal 44 is of a type having an inner metal core and an outer rubber coating. Preferably, the seal 44 is co-extruded in a conventional manner. The crimping tool 10 is positioned over the open seal 44 until the shaped rollers 28 and 30 are at the same general elevation. The crimping tool is energized causing the pneumatic cylinder 32 to move and responsively pivot driven shaft 22 from the open position to the closed operative crimping position squeezing the seal 44 to close onto the flange 46. The driven gear 40 will meshingly engage with driving gear 36. At the same time as the energization of pneumatic cylinder 32, the pneumatic motor 14 is energized causing rotation of driving shaft 16. The crimping tool 10 will then travel along the flange closing the seal 44 progressively.
The invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. lVlany modifications and variations of the invention are possible in Light of the above teachings. Therefore, within the scope of the appended claims, the invention may be practiced other than as specifically described.
