Definitions

  • Bench mounting device for a conventional hand tool having two handles comprises a frame on which there is provided a tool head clamping means adapted to clamp the tool in a pre-determined position.
  • a pair of handle closing levers are mounted adjacent to the clamping means on a parallel spaced-apart axis and extend divergently with respect to each other.
  • the ends of these levers are adapted to engage the ends of the handles of the tool so that when the levers are swung towards each other, they will move the handles from their open to their closed positions'
  • the levers are swung by a slide actuator which is movable along a path extending away from, and towards, the clamping means. Rollers on the slide engage the levers to swing them towards each other when the slide moves away from the clamping means.
  • This invention relates to tool holders and actuators for hand tools which are affective to convert a conventional hand tool into a semi-automatic bench apparatus.
  • the invention is herein disclosed in embodiments particularly adapted for use with two different types of electrical terminal crimping tools.
  • the principles of the invention can be adapted to the construction of tool holders and actuators for a wide variety of hand tools.
  • the process of crimping electrical terminals onto wires is a relatively precise and exacting one and close control of the crimping operation is required for the achievement of optimum mechanical and electrical connections between the terminals and the wires.
  • Electrical terminal crimping operations therefore require precisely constructed tooling, either hand tools or automatic orsemi-automatic bench mounted tools.
  • Automatic and semi-automatic terminal crimping apparatus are used wherever large numbers of terminals are to be crimped onto wires and there is economic justification for a relatively high investment in the crimping tooling.
  • Circumstances do arise under which intermediate numbers of terminals must be crimped onto wires although the volume is not sufficient to justify installation of automatic or semi-automatic crimping machines; for example, many electrical harness shops use limited numbers of some types of terminals and, while they may have automatic machines for the terminals which they use in large volume, they commonly use hand tools for those special terminals which they use in only limited numbers. It thus becomes necessary for an operator to crimp perhaps several hundred or several thousand terminals onto wires by means of manually actuated hand tools and this type of crimping operation is fatiging on the operator, time consuming, and relatively expensive because of the fact that the production rates are relatively low as compared with those achieved with automatic or semi-automatic crimping machines. Under such circumstances, a simple adapter and actuator for the hand crimping tool would be extremely useful to users of limited numbers ofa particular type of electrical terminal.
  • a further object is to provide a bench mounting means and actuator for a hand tool.
  • a further object is to provide a bench mounting means and actuator for an electrical terminal crimping tool.
  • a further object is to provide a bench mounting means and actuator which is adapted to be used with a variety of specific types of crimping tools.
  • a further object is to provide a bench mounting means and actuator which is particularly designed to apply a relatively high force to the tool handles at the end of the handle closing stroke.
  • a further object is to provide an apparatus which is relatively foolproof in operation, and which permits the achievements of a substantial improvement in the production rate obtainable from a hand crimping tool.
  • FIG. I is a frontal view of one embodiment of a tool holder and actuator in accordance with the invention, this view showing the normal positions of the parts.
  • FIG. 2 is a view similar to FIG. I but showing a hand tool mounted in the tool head holding means.
  • FIG. 3 is a view similar to FIG. 2 but showing the positions of the parts at the conclusion of the operating cycle when the handles have been moved from their open to their closed positions.
  • FIG. 4 is a sectional view taken along the lines 44 of FIG. 2.
  • FIG. 5 is an exploded view of the tool head clamping means of the embodiment of FIG. 1.
  • FIG. 5A is a fragmentary perspective view of the head of a tool of the type adapted to be mounted in the embodiment of the invention shown in FIGS. 1-5.
  • FIG. 6 is an exploded view of the parts of an alternative form of tool head clamping means in accordance with the invention.
  • FIG. 6A is a fragmentary perspective view of the head portion of an alternative form of tool for which the clamping means of FIG. 6 is adapted to be used.
  • FIG. 7 is a fragmentary view showing the tool head of FIG. 6A mounted in the clamping means of FIG. 6.
  • FIG. 8 is a diagram which illustrates the operation of the disclosed embodiment of the invention.
  • a typical hand tool 2 for crimping electrical terminals onto conductors comprises a tool head 4 having a pair of divergently extending handles 6, 6'.
  • the tool head has a frame block 8 to which are attached face plates 10 on each side thereof.
  • the upper ends of the handles 6, 6' are connected to the lower ends of the plates 10 by means of links l2, 12' which are pivoted to the lower ends of the plates and to the handles.
  • the handles are also pivoted to each other at 14 and to a reciprocable ram 16 which extends between the plates 10 and into the tool head block 8.
  • Ram 16 has movable crimping dies 18 on its upper end which are cooperable with fixed crimping dies 20 mounted in the tool head.
  • the disclosed tool also has rachet type full-stroke compelling mechanism 22 pivoted to, and extending between the handles to ensure that when the handles are closed, they will be completely closed before they can be opened so that the terminal being crimped will be fully crimped rather than partially crimped.
  • the general type of hand tool 2 shown in FIGS. 2 and 5A is described in further detail in US Pat. No. 2,914,976.
  • a tool holder and actuator adapted for use with the hand tool 2 comprises a frame or housing 24 having a backwall 26, sidewalls 28, a base 30, and a topwall 32 the central portion of this top wall being elevated as shown at 34.
  • a transverse frame rib 36 extends between the sides of the elevated portion of the topwall and vertical ribs 38 extend from the backwall as shown. These vertical ribs and the transverse rib 36 serve to support portions of the actuating means and the mounting means for the tool as will be described below.
  • a tool head mounting means is provided on the upper side of the housing on the topwall portion 34 and comprises a mounting plate 40 having a first vertical plate section 4 2, a horizontally extending plate section 44 integral with the plate sections 42, a depending flange 46 which extends from the rearward edge of the horizontal plate section 44, and an obliquely downwardly extending ear 48.
  • the mounting plate 46 is se cured to the transversely extending frame rib 36 by means of two shoulder screws 50, 50' the reduced diameter ends of which are threaded into the rib 36 so that the shoulders of these screws bear against the plate section 46 of the mounting plate 46.
  • the unthreaded larger diameter portions of the screws 50, 50 serve as pivotal axis for handle closing levers 76, '76 described below.
  • a pair of clamping blocks 54, 54' are mounted against the face of the plate section 42 of mounting plate 40, the block 54' being fixed to the block by a fastener 56 while the block 54 is clamped to the plate section 42 by a thumb screw 58.
  • This screw extends through an opening in the block 54, through an elongated slot 64) in the plate section 42 and is threaded into a clamping plate 62 on the rearwardly facing side of the plate section 42.
  • the end of screw 58 normally extends through the left hand end of the slot 60 and a pin 64 mounted in the plate 62 extends into the slot on the right hand side thereof as view in FIG. for reasons which will be explained below.
  • Blocks 54, 54' have upwardly projecting ears 66, 66 and a spring band 68 is riveted or otherwise secured to the outwardly facing sides of these ears.
  • the opposed faces 70, 70' of the blocks 54, 54 have rectangular bosses 72, 72 thereon which define upwardly facing shoulders adapted to bear against the underside 74 of the tool head frame block 8.
  • the tool handles 6, 6 are swung inwardly towards each other or closed by means of two handle closing levers 76, 76 which are pivoted at their upper ends as viewed in the drawing on the previously identified shoulder screws 50, 50.
  • These levers are normally resiliently biased by means of torsion springs 78, 78' which surround sleeves 79, 79 mounted on the shoulder screws 50, 50 and have ends 80, 80' which extend behind the levers and over one edge thereof.
  • the other ends 82 of the springs extend into an opening in the plate section 44 to prevent movement thereof.
  • the springs thus bias the levers to the positions shown in FIG. 1 but permit arcuate movement ofthese levers relatively towards each other to the positions in FIG. 3.
  • the distal or free ends 84, 84 of the levers are bent outwardly as shown at 84 and upwardly at 86 to define a pocket across which pins 90, 90' extend.
  • Rollers 88, 88 are mounted on these pins and are adapted to engage the outwardly facing edges 92, 92' of the outer ends of the tool handles 6, 6'.
  • the levers are of lengths such that the rollers will engage the handles at the optimum locations for the application of closing force thereto.
  • the levers are swung inwardly towards each other by means of an actuator comprising a slide 94 which is supported on the surfaces and extensions of the surfaces of the ribs 38, gib plates 96 being mounted on these ribs and having portions extending over the edges of the slide 94 to secure it in its position.
  • an actuator comprising a slide 94 which is supported on the surfaces and extensions of the surfaces of the ribs 38, gib plates 96 being mounted on these ribs and having portions extending over the edges of the slide 94 to secure it in its position.
  • a rearwardly extending flange 98 is provided on the lower end of this slide member and the piston rod Hill of a pneumatic piston cylinder 102 is secured to this flange by suitable fastening means as shown.
  • Piston-cylinder M2 is vertically mounted adjacent to the backwall 26 and is secured at its lower end to a web 104 which extends from the backwall.
  • a pair of spaced-apart rollers H0, 110' are mounted on the slide at its upper end on pins 112, 112', these rollers normally bearing against the outwardly facing edges 1114, lid of the handle closing levers 76, 76'. As the side moves downwardly, these rollers thus move relatively over the edges H4, 114' and cause the levers to be swung inwardly and towards each other. It will be noted that the edges 114, M4 are straight, however, these edges can be contoured in the manner of a cam if it is desired to develop a high force on the tool handles at some particular stage of the operating cycle.
  • a terminal is located between the crimping dies and the wire is located in alignment with the terminal between crimping dies.
  • compressed air is admitted by a suitable valve such as a foot valve (not specifically shown) to the upper side of the pneumatic pistoncylinder 102.
  • a suitable valve such as a foot valve (not specifically shown) to the upper side of the pneumatic pistoncylinder 102.
  • the piston rod and the slide move downwardly thereby causing the rollers 110, E10 to travel relatively over the edges 114, 114 of the levers 76, 76'.
  • the levers are thus swung inwardly and by virtue of the engagement with the lower ends of the handle 6, 6, the handles are swung inwardly.
  • the compressed air is exhausted from the cylinder and the slide is returned to its normal position under the influence of the return spring.
  • the dies then move downwardly and the crimped terminal can be removed from the tool head.
  • a hand tool can be clamped in the tool head clamping means in an extremely short time and that the terminals can be crimped onto wires at production rates which are substantially in excess of the rates which can be achieved by manual operation of the same tool. It will also be apparent that the disclosed form of the invention is relatively simple in construction and thereby provides an extremely efficient and low cost means for increasing the productivity of a given hand tool and reducing the operator fatigue which is usually attendent to the hand tool crimping of terminals on to wires.
  • FIG. 8 shows the linear travel of the ends of the levers 76 as a function of the travel of the piston (or slide) during movement of the slide from the position of FIG. 1 to the position of FIG. 3.
  • the data points of this curve assume that a piston having a5 inch stroke is used and that about 7.7 inches of handle travel are required for complete closure of the tool handles (i.e., about 3.35 inches of travel for each handle). It will be apparent from this curve that during the first 3 inches of slide travel (representing 60 percent of the stroke of the piston) the handles are swung through a total of 7 inches of travel or about 90 percent of the total travel required for closure of the handles.
  • the disclosed embodiment of the invention is thus advantageous in that a large portion of the total stroke of the piston is available at the end of the stroke of the handles for the development of the high force required at the end of the crimping operation. Stated another way, very little work is performed on the terminal by the piston during the initial portions of the crimping operation but the amount of work performed in the final stages of the operation rises abruptly. The fact that this work is available is evident from a review of the area under the final portion of the curve of FIG. 8.
  • rollers 110 are engagement with the levers 114, 114' adjacent to the lower ends so that a high mechanical advantage is obtained in the roller-lever relationship as well as by virtue of the distance travel-handle travel relationship discussed above.
  • FIGS. 6, 6A and 7 show an alternative form of tool head clamping means adapted to clamp a tool 116 in the apparatus.
  • This type of crimping tool comprises a pair of closeable tool jaws 118, 118' which are pivotally connected at their lower ends to handles 120, 120'. As with the previous embodiment, these handles extend divergently from the lower end of the tool head and are pivoted to each other adjacent to their upper ends at 122.
  • the jaws 118, 118' are also connected to each other by straps 119 on each face of the jaws, only one such strap being shown in the drawing.
  • the head clamping means of this alternative embodiment comprises a U-shaped clamping frame 126 having sides 128, 130 and a web 132 extending between these sides at their left hand ends thereof as view in FIG. 6.
  • the frame 126 is secured to the face of the plate section 42 by means of screws 138, 139, 141, the screw 138 extending through aligned holes in the sides 128, 130 and through a round screw hole in the plate section '42, a nut 140 being provided on the end of fastener 138 as indicated.
  • the fastener 141 extends similarly through aligned holes in the ends of the plate sections and through the previous identified slot 60, a nut 143 being provided on the end of this fastener.
  • Fastener 139 extends through additional holes in the plate sections and has a nut disposed between the plate section 130 and plate section 142. As shown, suitable spacers surround the intermediate portions of the fasteners 139, 141 to support the free ends of the sides 130, 128 of the frame member 126.
  • a U-shaped clamping yoke 142 having arms 144, 146 and a web 148 extends-through an opening 152 in the web 132 of the clamping frame.
  • the ends of the arms 144, 146 are outwardly turned they are shown at 150, and extend into slots 154, 156 in the sides 128, 130 of the fixed clamping frame.
  • the right hand end of slot 154 as viewed in FIG. 6 is enlarged as shown at 158 for reasons which will be explained below.
  • Clamping yoke 142 is slideably mounted in the clamping frame and can be moved leftwardly from the positions of FIG. 7 by means of a pin 160 having an enlarged kurnled end.
  • the pin extends through a hole in the yoke or web 148 and a snap ring 161 is affixed to the pin on the inner side of the web 148 to prevent axial movement of the pin relative to the yoke while permitting rotary motion of the pin relative to the yoke.
  • the inner end of the pin 160 extends through the opening 152 and a locking pin extends transversely through and beyond the surfaces of the pin 160. The length of this locking pin is greater than the width of the opening 152 so that the pin 160 can be locked in position as will be explained below.
  • the han- -dle portion of the pin 160 is first turned until the transverse locking pin clears the marginal edges of the web 148 and the pin 160 is then moved leftwardly.
  • the tool 116 is then positioned beneath the frame 126 and moved relatively upwardly until the inwardly turned ends 136, 136' of the ears 134, 134' engage the upper edge of the plates 119 on the tool, upward movement of the tool beyond this position is being prevented by these inwardly turned ears.
