Description

The The invention relates to working and holding racks on which large-sized workpieces from launched and clamped individual components by tack welding, welding, Soldering and gluing are joined. Through a modular design is an ergonomically favorable working position of these Activity executing employees realizable.

known State of the art in workshops of the metalworking Mechanical and plant engineering as well as the locksmith's trade is the Application of work tables and working and holding racks sufficient load capacity and rigidity, taking on the usually horizontal table top to be joined together Single components are placed, positioned and clamped. The clamping of the individual components takes place by means of workpiece contour and desk-dependent dimensioned and positioned Clamps, clamping bolts, clamping screws and other usual in device construction Functional elements attached to the outer edges of the tabletops and support rails or in matching table openings and table bores are received and held.

Such a work table, which is used in particular as a welding table, is out EP 0541904 known. The horizontal table top made of cast iron is positioned on steel supports or legs. These welding tables can be moved through the arrangement of articulated wheels or rollers on the table legs in workshops and positioned to change location. The table tops and their front cheeks are designed with a known hole pattern for the positioning and attachment of clamping and functional elements.

adversely for a realignment, implementation and flexible application This work table is their heavyweight, the large area and the only horizontal arrangement of the table top in a uniform constant height.

Of the the joining work executing employees is thereby partly ergonomically handicapped.

was standing The technology is therefore also work frames for implementation of joining work, taking on a closed table top is waived.

To DE 20 2006 020 012 U1 is the base part for joining individual components to form an overall component of a clamping frame, are positioned on the workpieces around, the clamping and functional elements werkstückkonturabhängig. A disadvantage of this solution is the large-scale expansion of the arranged here in a horizontal position frame-shaped lightweight table.

This in DE 20 2006 011 216 U1 described, described as trimming and welding system modular working and holding frame consists of intersecting horizontal double-T-beams, which are equipped with a breadboard. On a table top is omitted, so that a level identical continuous support surface for individual components and workpieces is not available. The advantage of the lightweight stand against the disadvantages of the limited rigidity of this working and holding rack in large-sized heavy-weight workpieces. The series arrangement of the through holes when using less double-T-beam is only limited for the modular joining of the individual carriers to the working and holding frame and for positioning and clamping the clamping and functional elements available.

• - A modular lightweight construction a physically facilitated frame structure and transport
• - A flexible, the nature of the joining process and the workpiece contour adapted arrangement of construction and functional elements and
• - A relaxed and optimized posture and working position of the employee working there

are feasible.

The Problem is solved by the claim 1.

The respective, according to the technological conditions of the intended Joining process and the workpiece contour designed modular work and support frame is structured so that out An assortment of carriers, strips, plates and adjusting and functional elements a sloping roof-shaped or a flat roof-shaped frame is formed. By Screws or locks are the parallel or yourself crossing steel profile bars, the carrier bars and / or other tabletops as well as the clamping and adjustment elements for the workpiece components, stiff and precisely adjusted, connected with each other.

Further Embodiments of the invention are in claims 2 to 5 indicated. You regarding the determination of the species and the more precise Training of the steel profile bars, the carrier bars as well the arrangement of table tops and other functional and connecting parts.

The The invention is simplified in some embodiments shown in the figures and in the following part of the description explained in more detail:

1 a view of a working and holding rack in double pitched roof shape

2 a view of a working and holding rack in pitched roof shape

3 a plan view of the workpiece support plane of the working and holding rack after 2

4 a view of a working and holding rack with table tops in flat roof shape

This in 1 shown modular working and holding frame consists essentially of the frame legs 6 same length, on the bottom plate 8th stand and by means of connecting straps 7 stiffened against each other. At the upper ends of the frame legs 6 are two frame frames, arranged in a double pitched roof shape, by means of adjustable hinge elements 9 attached. The frame frames form two inclined workpiece support planes 1 through bolted and locked connections of parallel arranged steel profile bars 2 , Carrier strips, these connecting cheeks 5 , Connecting straps 7 and a tabletop 10 ,

All built-in steel profile bars 2 form a ⨅-profile. In their holes, not shown equal spacing are along the contours of the workpiece-individual components to be joined by tack welds, clamping and adjusting elements 4 positioned and adjusted for the workpiece to be joined.

That in the 2 and 3 shown modular working and holding frame has a simple pitched roof shape. The pitch frame forming frame frame is in an increasing angular position on the frame legs 6 arranged. Due to the oblique position is a sloping rising workpiece support level 1 educated. By at least two frame legs 6 , In different standardized length dimensions, at the upper ends, end-side connecting plates are arranged, via a respective hinge element 9 a firm connection with the frontal cheeks 5 the frame frame forming ⨅-shaped steel profile bars 2 , which are firmly and accurately positioned against each other.

The frame legs made from an existing assortment of stepped standard lengths 6 selected support elements allow employee-dependent optimized for an ergonomic working position and posture tilt and height of the workpiece support plane 1 , About the at the lower ends of the frame legs 6 Frontally arranged connecting plates is the modular working and holding frame on a base plate 8th safely and accurately supported on the floor of the workshop room.

From the top view in 3 on the sloping frame after 2 is derivable that the workpiece support plane 1 forming frame is rectangular and made of four ⨅-shaped interconnected steel profile bars 2 consists. Between these are two, in the particular position determined by the contour of the workpiece, not shown, supporting strips 3 arranged. These too have an example of a ⨅-shaped strip profile. On the rack frame are also exemplary seven clamping and adjusting elements 4 arranged for the workpiece to be clamped during the joining process. The clamping and adjusting elements 4 are with bolts in holes not shown on the carrier bars 3 , held, positioned and locked individually.

This in 4 illustrated, used for example for welding modular working and holding frame has a flat roof shape. Height-adjustable and precisely adjustable frame legs 6 the same standard length are horizontally abutting and intersecting steel profile bars 2 , formed in ⨅-profile shape, two rigid rectangular table tops 10 in different standardized length and width dimensions. The level of the same upper and contact surfaces is a work piece level 1 , greater length extension for large-sized long workpieces formed.

Because these tabletops 10 Usually equipped with row and grid arrangements of mounting holes, a very flexible arrangement of clamping and adjusting elements in a variety of positions, workpiece contours is dependent, possible. The two tabletops 10 are made of cast iron, for example.

The in the 1 to 4 shown exemplary solutions show that by different lengths of the frame legs, employee-specific inclinations of the frame and flexible dimensions of the modularly connected work and holding frames in lightweight construction ergonomic workplace design Staltung for joining processes under workshop conditions can be realized.
