Definitions

the present invention relates to a clamping device with a body, two jaws facing each other arranged on the body and along a common axis towards and away from each other are guided away adjustable, one between the jaws fixed to the body center cheek, and a Actuator for adjusting the clamping jaws with a Adjusting spindle, which at its axial end portions male threaded sections having opposite slope, which are screwed into the jaws, and those at their intermediate portion between the male threaded portions is rotatably held in a bearing housing, which in the body coaxial with the jaws adjustable is guided.
Clamping devices of this type are known and are in used in practice, for example, on a components Machine table o. The like.
the known clamping devices are usually designed and include in the manner of a vise two jaws made by the rotation of a spindle on each other to or away from each other are adjustable to clamp a component between them (centric clamp).
centric clamp Alternatively, clamping devices are known in which provided between the jaws a center jaw is to simultaneously clamp two components (Double-release).
Double-release There are also clamping devices in which only one jaw is adjustable and against one clamps fixed jaw. All three types of clamping devices are needed in practice.
the invention is the task based, a clamping device of the aforementioned To train type so that they converted with little effort can be and thus for different clamping types can be used.
the Bearing housing and / or at least one clamping jaw on the Basic body can be fixed to a relative movement the bearing housing and / or the at least one clamping jaw to prevent against the body, and that the center jaw is releasably attached to the base body.
a conventional Tighten double tensioner so that it simultaneously as a centric vice or as a tensioner with a fixed jaw can be used.
Locking devices provided over which optionally a clamping jaw or the bearing housing can be firmly connected to the body, so that a relative movement is no longer possible.
a clamping jaw fixed to a base body, so only the other jaw is movable with the Result that the tensioning device according to the invention (at removed center jaw) as a tensioner with a fixed Clamp works.
this can also Bearing housings are fixed at a predetermined position, so that the jaws with removed center jaw clamp a component centric, so the clamping device works as a centric clamp.
the clamping device according to the invention can be convert in a simple way, as a double vice, Centric clamp or as a clamp with a fixed jaw to be used. So are three different Clamping devices in the clamping device according to the invention united.
the clamping device 1 is basically designed in the manner of a vise and comprises two jaws 2, 3, which are opposite to each other arranged on a base 4 and along a common axis towards and away from each other are guided adjustable.
the jaws 2, 3 are in two parts formed and each consist of a Grundbakkenelement 2a, 3a, which is displaceable in the main body 4 is inserted, and one at the top of the Base jaw element 2a, 3a screwed essay stack element 2b, 3b.
the main body 4 has a substantially U-shaped, to the main body top open cross section, in which the base jaw elements 2a, 3a are used.
the base jaw elements 2a, 3a are known per se Way connected by an actuator in such a way, that they are together towards each other or from each other can be moved away to stretch a component or to solve.
This actuator includes an adjusting spindle 5, in its central region 5a in a bearing housing. 6 is rotatably mounted. Has at its axial end portions the adjusting spindle 5 external thread sections 5b, 5c, the in each case a base jaw element 2a, 3a screwed are, wherein the two external thread sections 5b, 5c opposite Have slopes, so that a turn the adjusting spindle 5 in one direction causes that the jaws 2, 3 are moved towards each other, and a rotation in the opposite direction to it leads that the clamping jaws 2, 3 moves away from each other become.
the adjusting spindle 5 on the bearing housing 6 via two plate spring packets 7, 8 held tight, on opposite sides from an inwardly directed web 6a of the bearing housing 6 are arranged and between the web 6 a on the one hand and a flange 9 of the adjusting spindle 5 or one screwed onto the right threaded portion 5c Support clamping nut 10.
the arrangement is made in this way, that the adjusting spindle 5 relative to the bearing housing 6 can be moved axially, but an axial clearance between the two components by the biasing force of Disk spring packets 7, 8 is prevented. It can the original orientation can be changed by the Clamping screw 10 is adjusted accordingly.
a flange 12 attached, which is the adjustment of the right clamping jaw 3 limited to the outside. Otherwise, the right-hand side End of the adjusting spindle 5 is formed as a hexagonal head 13, on which a key can be set up, to actuate the adjusting spindle 5.
a Center jaw 14 bolted each with a top jaw element 2b, 3b cooperates to simultaneously two components to be clamped on corresponding bearing surfaces the center jaws 14 on the one hand and the top jaw elements 2b, 3b are positioned on the other hand.
the clamping jaws 2, 3 by turning the adjusting spindle. 5 moved towards each other, wherein by the possible relative movement between the adjusting spindle 5 and the bearing housing 6 ensures a uniform clamping of both components becomes.
Conversion device 1 to convert such that a component between the two jaws 2, 3 centric tensioned can be.
the center jaw 14th by loosening the fastening screws from the main body 4 removed (see Figure 4).
the bearing housing 6 secured to the base 4 against axial movement. These are in the U-legs of the body 4 on the one hand and the bearing housing 6 on the other corresponding Through holes 15, 16, 17 formed, in which a bolt o. The like. Can be inserted to firmly connect the bearing housing 6 to the main body 4, so that between the two components no relative movement can take place.
the clamping device 1 so that a component against the left Clamping jaw 2 can be clamped as a fixed jaw.
the main body 4 and the bearing housing 6 solved again, so that the bearing housing 6 can be moved axially in the base body 4.
the base jaw member 2a of the left Clamping jaw 2 firmly connected to the base body 4, so that the jaw 2 with respect to the base 4 no longer can be adjusted.
These are in the thighs of Base body 4 and in the base jaw member 2a also mutually corresponding through bores 18, 19 formed, in which a bolt can be inserted, to make a connection between the components 2, 4. If by inserting the bolt such a solid Connection is made by an operation the adjusting spindle 5 only the right clamping jaw 3 moves.
