The innovation relates to a support frame for support From äüf einin Boar-beitiingoraaSCriincnbott äüfgöspäiin— th workpieces.

Spatially extended workpieces, which may still have an asymmetrical shape, often have to be machined be supported in several places on the machine bed. It is known to support wooden supports use. In many cases it is necessary for ein.3 precise workpiece machining that a certain distance between the machine bed and the point to be supported is observed. The creation of a wooden base that this Distance is adjusted, takes a considerable amount of time. For differently shaped workpieces such a wooden base can usually no longer be used. The support of workpieces with wooden parts is therefore costly and time consuming.

The innovation is based on the task of a support bracket

for trimming clamped on a processing machine bed Developing workpieces easily, quickly and precisely at different distances between the machine bed and Auflagesteii ^ ajp workpiece can be adjusted,

The object is achieved according to the invention in that a guide holder is attached to a foot that can be placed on the machine tool bed, in which an extendable shaft is arranged, which can be fixed in stages on the guide holder in predetermined steps and has a threaded hole running in its longitudinal direction, In which a threaded bolt is used, which is used for fine adjustment of the height and on whose end protruding beyond the shaft the workpiece can be placed. A particular advantage of this arrangement can be seen in the fact that the uDii / auiwemu iur mc ituovu uZuug σχυσχ- ucöi / XiiuiH / Cii ouexis cj.xj.oS tools is considerably reduced; The »support frame can be set up at the desired point on the machine bed in just a few simple steps and extended to approximately the required length using the step adjustment. The fine adjustment can then be made by turning the threaded bolt. A rigid connection between the workpiece and the machine bed can be established with a clamping claw arranged close to the installation site of the support frame. Another advantage of the support block is that it can absorb a high pressure load. It is therefore possible to support heavy workpieces on the support frame. An additional advantage of the support frame is the secure footing provided by the foot. This reduces the risk of accidents

The threaded bolt is preferably provided with a hexagonal head. The support block can therefore by means of a

Set tools with which heavy workpieces, if necessary, can be raised a certain distance to a desired support height without difficulty,

An advantageous embodiment is that the Shank has a round cross-section and is provided with annular incisions, which are at regular intervals are arranged from each other, and that one can be pushed into a recess protruding beyond the guide holder Use with a part protruding over the incision on the face of the guide holder supported, which is designed as a tube. This arrangement is characterized by its simple design. The support bracket contains only a few parts that are quick and easy to assemble. This results in an economic advantage

In a favorable embodiment , it is provided that the insert is designed as half of a ring with a rectangular cross-section and has a projection to which a chain connected to a projection ara guide holder is connected. The Eineatz for the fixed setting a certain height is captive in this arrangement with the support frame. This not only simplifies the handling, but also the storage of the support bracket.

In a preferred embodiment, the shaft is on its end arranged in the guide holder over a certain amount Length not provided with notches. The end of the shaft not provided with incisions remains at a maximum set height in the guide holder. This arrangement creates a secure connection between the shaft and

A round, extendable shaft 18 is located in the guide holder 12 arranged, which is provided with annular incisions 16, which are arranged at regular intervals from one another are. The shaft 13 contains a threaded bore that runs in its longitudinal axis and is not shown in more detail. The opening of this threaded hole is located on the end face of the which is not arranged in the guide holder 12 Shaft IS.

A threaded bolt 24, which is provided with a hexagonal head 22, is inserted into the threaded hole. The point to be supported by the support bracket 1 on a workpiece (not shown in detail) rests on the head 22 of the threaded bolt Zl ₊ .

In a protruding beyond the end of the guide holder 12 Notch 16, an insert 26 can be inserted which has a semicircular opening which is not designated in any more detail is. The diameter of the opening is adapted to the outer diameter of the shaft 1 at the bottom of an incision 16. The incisions 16 can have a rectangular cross section. The insert 26 is also corresponding formed rectangular in cross section over its length. The insert 26 pushed into an incision 16 also protrudes its outer part beyond the incision 16. This outer, over aen notch 16 protruding part can on the upper end face 20 of the tubular guide holder 12.

The insert 26 may be in the shape of one half of a ring. It is advantageous to lengthen the ends of the ring half in the tangential direction. As a result, a secure support of the shaft 1o via the insert 26 remains

the end face 2o obtained when the insert 26 in the plane of the end face 20 by a piece radially to the Shaft 18 aach, is shifted outside.

In the middle of the insert 26 is a projecting, semicircular bent pin 32, the ends of which are on the insert 26 are welded on. At the protruding pin 3 <_ a chain 28 is connected, the other end in a semicircular, from the side wall of the guide holder 12 protruding pin 30 is suspended. Through the chain 28 is the use 26 movably and captively connected to the guide holder 12.

The lower support surface of the foot 10 is machined flat. This measure improves the stability. An incision, not shown in detail, may be present in the footplate 10 be the one for attaching the foot 10 to a machine bed, not shown, with the aid of clamping claws suitable is"

With the support bracket 1, workpieces clamped on a processing machine bed can be supported. As the support frame 1 is placed at the desired point on the machine bed (not shown), a rough adjustment of the desired height is first made with the aid of the shaft 18, which can be fixed in certain height levels by the division given by the incisions 16. The shaft 18 can be pulled out of the guide holder 12 by the appropriate height in a very short time. With the aid of the insert 26, the shaft is held at the set height. The fine adjustment of the height is then made by turning the threaded bolt 2 / f. The threaded bolt Zk is so far

the shaft 18 unscrewed until the hexagonal head 22 the Has reached position in which there is a not shown to be supported point of a workpiece.

The support block 1 can absorb large compressive forces. If a workpiece is already resting on the hexagonal head 22, a subsequent change in the support height can be made without difficulty by rotating the threaded bolt Zk. By using a wrench to be attached to the hexagon head 22, the

Readjustment of the required force even with workpieces with large weights only slightly.

The shaft 18 is not provided with incisions over a certain length _{at its end 1Z +} arranged in the guide holder 12. When the shaft is pulled out to the maximum height setting, the end not provided with incisions remains in the guide bracket 12. This ensures that the shaft 18 is held securely when the support height is high,

It is useful to measure the lengths of differently sized support brackets 1 to adapt to each other in order to continuously adjust the support heights lying in a certain area can. This is achieved in that the total length of the guide holder 12 and shaft 18 of a support block 1, whose guide holder is set to the maximum height, the height of the guide holder de3 in the next step larger support block 1 corresponds.

The support bracket 1 according to the innovation is easy to transport and in a few simple steps to the desired height
