FR2492302A1 - Universal jig for engineering workshop - uses frame metal sections connected by bolting and platens for e.g. automobile redressing - Google Patents

Abstract

The universal jig uses metal sections (1,2) and platens (3,4) and assists centering, redressing, blocking, re-aligning and measuring etc. of chassis, decks, bodies and masonry construction. The metal sections and platens may be connected by bolts so that they intersect, are juxtaposed or are superimposed. The plates may be mounted on rollers or fixed and the sections and plates may include graduated scales whilst locating different fasteners and accessories.

Description

 The present invention relates to workshop tools of the "template" type making it possible to: straighten, line up, clamp, block, measure: the hulls, chassis, bases, platforms and elements of composite assemblies, for example of damaged motor vehicles .

 In the known devices of this kind, the accessories are too numerous, fragile, of awkward use and which requires an additional place, address, technical knowledge and especially of time of setting in function.

 The universal template according to the invention makes it possible to avoid these drawbacks: by its simplicity, its maneuverability, its solidity and its speed of operation.

 Usable from four basic standard elements allowing on one of its elements to adapt as necessary the necessary tools: positioning, plunging, clamping, blockages, checks of chassis bodies, underbody and elements of all types and all brands.

 The device according to the invention can be fixed level by: screws, welds, seals to: marble, lifting platforms, fixed and rolling platforms, fixed and rolling bases, floors made of hard materials.

 The attached drawing in perspective shows the principle, consisting of four basic standard elements: a) Two longitudinal open sections 1, the opening allowing the passage of the screws and the sliding of the upper and lower plates 3 and 4. b) Three 2 transverse profiles of the same section as profiles 1, all three identical, each pierced in its base with two equidistant holes from a fixed point in the center: this fixed point being a tapped hole in a plate welded to the center of the upper part of the profile 2. This tapped hole allows a cam to receive a cam 9. This cam receives the connecting rods 8 for adjusting the spacing, the two holes in the base of the profile 2 are used for fixing and blocking the profiles 1 and 2 between them. c) Several plates 3 and 4. The plates 4 have three tapped holes with equal centers, The plates 3 of the same format, but with smooth holes.

 Using three screws, the tightening between the plates 3 and 4 allows the device to be locked in multiple positions.

Still on the same plates 3 and 4 will be grafted, according to the needs of a job: clamping vices 5, sleeves 6 for operating the cams 9, connecting rods 8 for adjusting the spacing of the vices 5 mounted on plates 3.

 The use of profiles 1 and 2 fixed vertically to the walls or posts and using elements 3, 4 or 5 makes it possible to carry out alignment and straightening work requiring no chassis or underbody control.

The device, object of the invention, can be used in all cases where a line-up, control work is necessary on complex assemblies or in special straightening works, for example on damaged motor vehicles.
By its simple design, easy to use, this device becomes a tool with multiple services and c sounds, and can be used in all types of workshops, mainly in production workshops and repair workshops.

 The small number of constituent elements, some of which may also be identical, makes it possible to produce an economic module, reproducible at will to respond to major production problems such as: manufacturing of frames, frames, frames, etc. thus the layout, clamping, for welding, grinding, sawing, gluing, etc ... of different materials, in different industries.

 Many modifications in variants can be imagined without departing from the scope of the invention. The description and the diagram provided here constitute only one nonlimiting and nonlimiting example of embodiment.
