Description

Kulekontaktklemme. Ball contact clamp.

Den foreliggende oppfinnelse angår en kulekontaktklemme med The present invention relates to a ball contact clamp with

to bakker som er svingbare om en bolt på lignende måte som en tang, two jaws which are pivotable about a bolt in a manner similar to a pair of pliers,

og med et kilelegeme som kan forstilles vinkelrett på boltaksen langs en spindel, og som de bakre ender av bakkene glir på. and with a wedge body that can be adjusted perpendicular to the bolt axis along a spindle, and on which the rear ends of the slopes slide.

Ved en slik kjent klemme er kilelegemet rundt, d.v.s. konisk, og oppviser innvendige gjenger som tjener til innskruing av konusen på spindelen. Som folge av at kilelegemet er rundt eller konisk, har de bakre ender av bakkene bare punktformet berbring med konusen, .så trykket mellom de bakre ender av bakkene og konusen er meget stort, noe som forer til en sterk slitasje.på konusflaten. Videre må de bakre ender av bakkene gli på konusen i en meget lang bane, nemlig langs en spiral, for å gi en liten spriking av bakkene. Over denne lange vei må der således anvendes en stor kraft for å overvinne friksjonen mellom de bakre ender av bakkene og konusen. With such a known clamp, the wedge body is round, i.e. conical, and has internal threads that serve to screw the cone onto the spindle. As a result of the wedge body being round or conical, the rear ends of the slopes have only point contact with the cone, so the pressure between the rear ends of the slopes and the cone is very large, which leads to strong wear on the cone surface. Furthermore, the rear ends of the slopes must slide on the cone in a very long path, namely along a spiral, in order to give a small crack in the slopes. Over this long distance, a large force must therefore be applied to overcome the friction between the rear ends of the slopes and the cone.

Der er også kjent en klemme med to bakker som er svingbare A clamp with two hinged trays is also known

på lignende måte som en tang, og som svinges av et kilelegeme som de bakre ender av bakkene glir på, og som kan forstilles ved hjelp av en spindel. Denne klemme er imidlertid ikke egnet for kulekontakter. in a manner similar to a pair of pliers, and which is swung by a wedge body on which the rear ends of the slopes slide, and which can be adjusted by means of a spindle. However, this clamp is not suitable for ball contacts.

For at der ved tilbakeskruing av konusen, resp. kilen, i de kjente klemmer skal fås en automatisk åpning av bakkene er der i klemmene anordnet fjærer som trykker bakkene bort fra hinannen. For å unngå disse fjærer og oppnå en tvangsmessig åpning av bakkene blir det ifolge oppfinnelsen foreslått å la kilelegemet, hvis bredde er tilpasset de bakre ender av bakkene, gli med liten klaring på den på klemmebolten faststående spindel i dennes lengderetning, idet kilelegemet er dreibart forbundet med en skruehylse som står i inngrep med spindelen, og å feste omboyde tynnplater som danner slisser, på sideflatene av kilen. So that when screwing back the cone, resp. the wedge, in the known clamps an automatic opening of the slopes is to be obtained, there are springs arranged in the clamps which push the slopes away from each other. In order to avoid these springs and achieve a forced opening of the slopes, according to the invention it is proposed to let the wedge body, whose width is adapted to the rear ends of the slopes, slide with little clearance on the spindle fixed to the clamping bolt in its longitudinal direction, the wedge body being rotatably connected with a screw sleeve that engages with the spindle, and to attach curved thin plates that form slots, on the side surfaces of the wedge.

Fortrinnsvis har bakkene ved de bakre ender sideveis utragende tapper som står i inngrep med slissene. Preferably, the slopes at the rear ends have laterally projecting tabs which engage the slots.

En foretrukken utforelsesform av oppfinnelsen er vist på tegningen. Fig. 1 er et oppriss av kulekontaktklemmen montert på et kulehode. A preferred embodiment of the invention is shown in the drawing. Fig. 1 is an elevation of the ball contact clamp mounted on a ball head.

Fig. 2 er et tverrsnitt etter linjen IV-IV på fig. 1. Fig. 2 is a cross-section along the line IV-IV in fig. 1.

Klemmen er beregnet på å festes på et kulehode 1. Klemmen består av to bakker 2 og 3 som kan svinges om en bolt på lignende måte som en tang. Ut fra bolten strekker der seg en spindel 5 som en skruehylse 6 står i gjengeinngrep med. En kile 7 som omgir spindelen 5 med liten klaring, er dreibart forbundet med skruehylsen 6 ved hjelp av en flens eller krage. Bredden av kilen 7 bestemmer anleggsbredden av de på kilen glidende bakre ender 8 og 9 av bakkene 2 og 3. Ved de bakre ender 8 og 9 av bakkene 2 og 3 er der anordnet sideveis utragende tapper 11, 12, 13 og 14. På sideflatene av kilen The clamp is designed to be attached to a ball head 1. The clamp consists of two jaws 2 and 3 which can be swung around a bolt in a similar way to pliers. Extending from the bolt is a spindle 5 with which a screw sleeve 6 is threadedly engaged. A wedge 7 which surrounds the spindle 5 with little clearance is rotatably connected to the screw sleeve 6 by means of a flange or collar. The width of the wedge 7 determines the installation width of the rear ends 8 and 9 of the slopes 2 and 3 that slide on the wedge. At the rear ends 8 and 9 of the slopes 2 and 3, laterally projecting pins 11, 12, 13 and 14 are arranged. On the side surfaces of the wedge

7 er der ved hjelp av nagler 17 og 18 festet omboyde tynnplater 15 7, with the help of rivets 17 and 18, curved thin plates 15 are attached

og l6 hvis form er tilpasset formen av kilen. De omboyde partier av platene danner slisser som strekker seg parallelt med kileflaten, og som tappene 11, 12, 13 og 14 glir i. Ved bevegelse av kilen 7 nedover glir tappene 11, 12, 13 og 14 tvangsmessig på de omboyde partier av platene 15 og 16, hvorved de bakre ender 8 og 9 av bakkene 2 og 3 and l6 whose shape is adapted to the shape of the wedge. The bent parts of the plates form slots which extend parallel to the wedge surface, and in which the pins 11, 12, 13 and 14 slide. When the wedge 7 moves downwards, the pins 11, 12, 13 and 14 forcibly slide on the bent parts of the plates 15 and 16, whereby the rear ends 8 and 9 of slopes 2 and 3

beveges mot hinannen så bakkene 2 og 3 frigir kulehodet 1. moved towards each other so that the slopes 2 and 3 release the ball head 1.
