DE19903971A1 - Mechanical device for axially fixing symmetric and asymmetric bodies in slide guide - Google Patents

Abstract

The device has two cylinders of the same height fitted concentric inside each other whilst a concentric base ring closes the outer ring space on one side and flush between the two cylinders. Two identical inner cylinder parts fit on each other and rotate opposite one another at the connecting point. Two independent mutually rotatable self-locking regulating clamping systems fit in the center of the inner cylinder parts and each consist of four identical vertically flexible quarter cylinder jaw segments each offset by 90 deg . Profiled bolts fitted at right angles centrally on the backs of the jaws are spring guided in matched profiled sleeves (17-24) set horizontally in the ring space between the outer and inner cylinder and open on one side towards the center of the device.

Description

As is known, many devices for tensioning, holding, fixing and Processing of various objects, materials or materials almost completely Lich according to their specific requirements and the intended use purpose and are designed for universal use or deviating problems hardly suitable. Common universal clamping devices such as vice and clamp are through their rigid, by no means gentle locking mechanisms and their basic principle of only two parallel jaws can only be used to a limited extent. If the tightening is too strong or too weak, there is a risk of destruction or the lack of security, especially in the case of non-uniform shapes.

The invention specified in patent claim 1 is based on the problem that it for a variety of regular and irregular bodies with different Versions in profile, material properties, surface structure, flexibility, Sensitivity and volume changes no or only insufficient (universal) There are clamping devices that cover as many requirements as possible.

This problem is solved by the features listed in claim 1 automatic fixing, locking and retensioning by means of two against each other rotatable, but independent clamping systems in one axis made of flexible, one Working jaws solved for many areas of application.

The advantages achieved by the invention are in the new fields of application opening methodology for holding bodies, which can be integrated and expanded as well as the universal and thus commercially interesting usability that it enables many shapes of different bodies for the purpose of processing, Securing and positioning axially in the short or long term.  

With the ability to turn two superimposed sets against each other In addition to the double fixation that is possible on all sides, versatile options can be implemented to position the object to be exciting or to place certain parts in the to balance the resulting free spaces between the jaws and / or levels.

This fact is of importance. a., if irregularities are an optimal off hinder direction or protect associated, bulky, asymmetrical parts etc. should be.

This is a far-reaching axial centering of bulky profiles and parts is enough, even if the scope and cross-section change over a short distance.

Openings on both sides of the system extend the use to long parts and one targeted merging of separate bodies for subsequent processing about - e.g. B. - side openings.

As transportable, maintenance-free, uncomplicated and not necessarily locally bound ne device makes it easier to use in hard-to-reach places or in ge offer where conventional systems cannot be used.

Regardless of this, the system is integrated as a machine and system component capable.

The independent, flexible readjustment allows fabrics to be stretched, which due to specific properties of themselves or the exposed environment in the Vary scope.

Typical for this are various plastics, coatings, but also materials (woods), caused by natural processes such as aging, wet or dry volume, consi Change structure and structure.

If the fixation lasts longer, such differences may result dangerous impairment of the fuse in rigid connections.

In addition to the guaranteed protection, surface protection plays a role at sensitli and expensive materials play a role.  

Basic principle and structure

An embodiment of the innovation is shown in the drawings Fig. 2 + 3 and is, according to the preceding, basic description, explained in more detail in construction and functi principle.

Two concentrically nested, equally long cylinders of different Diameters are one-sided, the space between them is flush closing bottom ring stably connected. The inner cylinder consists of two superimposed, identical sub-segments, via a horizontal slide ring (e.g. tongue / groove, ball bearing, etc.) in the middle are axially rotatable against each other. Both sub-segments have four - to each other in their mantle at half height offset by 90 degrees - horizontal holes in alignment with right angles of their Axis. The drill holes in the lower segment are located in the outer cylinder jacket four adequate core holes, the rotatable upper segment an inner wall milled ring groove, exactly horizontally opposite.

Between the aligned holes in the lower segment and the Au External cylinders are four, only open towards the middle of the profile sleeves on the outside and inside permanently mounted (screwed, welded). Four other profile sleeves of the upper inner cylinder are also 90 to each other Offset and with the open side towards the center, horizontally with its holes firmly connected and fitted with the closed side in the annular groove opposite.

In each profile sleeve there is a spiral spring that fits in size and pressure behavior on which the profile bolts (alternatively to springs gas pressure bolts) resilient be performed.

The inside of the sleeve and the bolt are profile fits (triangles, squares, stars etc.) that work in one another without tilting.

The bolts are right-angled and centered with the backs of the inside cylinder identical clamping jaws connected in a ring. Four jaws, offset 90 degrees to each other, form centrally in the upper and lower part segment one each of two jaw cylinders.  

All jaws work independently of one another and consist of several vertical, only centrally connected, limited horizontally deformable to the outside Spring steel or plastic layers.

Analogous to the structure of the objects to be held, they are due to their two-dimensional Flexibility can be individually placed and deformed, but goes into yours after relief Starting position, which corresponds to the minimum position, back.

Make phases on the head and foot of each cheek - sloping from the outside inwards - easier the optimal approach and deduction of the body to be exciting.

Movable balls at the end of the sleeve, which not only allow optimal guidance, but also due to the back pressure of the springs via counterbores in the ring groove Can block turning ability, handles on the inner cylinder for easy ver turn or four, starting from the ring groove, offset by 90 degrees, of equal width and deep, vertical grooves to the beginning of the outer cylinder to close the rotating top remove etc., are conceivable execution options as well as in a short time exchangeable, changing jaw shapes.

Even an expansion via additional backdrops and clamping systems, also in ver set and contradictory axes, nothing stands in the way.

Size relationships, materials and appearance of the jaws, springs, sleeves, bolts, Cylinders etc. can be modified, but change the basic principle, working and we way of the device in any way.  

The drawings, Fig. 2 and 3, show a simple, fictional example of use Christmas tree stand for trunks 45-90 mm thick, all causalities in terms of working, function and dimensions (unnecessary details have been omitted).

The outer diameter of the 210 mm high outer (A) and the split, against each other on the rotatable 2 × 105 mm high inner cylinder (B) are 280 mm (B1) or 150 mm (B2) with material thicknesses of 10 (B1) or 05 mm (B2).

A 10 mm thick base plate (C), diameter 280 mm and in this case not broken, is welded concentrically to both steel cylinders. All eight profile sleeves made of steel ( 17-24 ), diameter 20 mm, are profiled on the outside as in a square square with dimensions of 20 × 10 mm and a length of 65 mm. In order to hold the upper four closed sleeve ends in a sliding manner, a ring groove that is horizontally opposite is milled 5 mm deep and 20 mm wide (fitting tolerances) into the outer cylinder inner wall. The square square steel bolts ( 1-8 ), 50 mm long, worked as a fit, are spring-loaded in the sleeves via spiral springs made of spring steel ( 9-16 ), between 15 to a maximum of 45 mm long.

In the passive state, four, 20 mm thick, identical jaws (D-K) form one of the two concentrically superimposed, 60 mm long cylinders in the center of the Device with 40 mm inside diameter.

The tree trunk is stretched downwards by the inside beveled, spreading Jaws pressed into the desired position using the rotary level (with crooked growth, Branch stumps, bark etc.) turned and then analogous to the upper one in the lower one Inserted the backdrop, where it locks itself, which ver further rotary movements prevents.

To automatically compensate for changes and fluctuations in the volume of the trunk tolerance distances of min. 5 mm to both maximum positions 100 and 40 mm stick. In the inner annulus water can prevent drying out, in the outer ballast for opti paint stand to be deposited.
