Definitions
- the invention relates to the field of tools carrying parts to be treated on the surface, and more particularly to painting parts for a vehicle equipped with a chassis.
- US Pat. No. 5,879,021 has proposed a trolley of adjustable size carrying a plurality of components to be painted by a painting installation. Such a trolley juxtaposes the parts to be painted side by side and allows them to be translated all the way through.
- the cost of treatment with such a tool is in particular proportional to the length of the carriage determined by the speed of translation inside the paint installation. The reduction in the cost of treatment is obtained in this way. document by the juxtaposition density of the pieces However the cost remains proportional to the size of the pieces to be treated
- EP-A-013 966 describes a device for holding vehicle parts making it possible to facilitate a painting operation. This document proposes a support adjustable in position to be able to adapt to different types of parts.
- US Pat. No. 4,872,963 describes a support for suspended parts.
- the support is conductive and makes it possible to hook a plurality of parts intended to be pleated in an electrolytic bath.
- the support described is connected to an electrode while each piece is in electrical contact with the carrier.
- Such tooling is well suited for very small pieces, but is not suitable for intermediate parts.
- This type of intermediate sheet part comprises for example pocket vacuum doors, or plaster hatches.
- These parts are often visible and exposed to the ambient environment so that it generally agrees that the treatment of these parts has the same aesthetic and technical characteristics as the treatment of the frame or the body of the vehicle.
- the corrosion resistance of these parts must in particular be harmonized with that of the chassis. Such corrosion resistance is often achieved by a cataphoresis treatment.
- the invention proposes a support tool for parts to be treated on the surface which solves these drawbacks, and allows a treatment whose characteristics will be identical to that of other types of parts, in particular identical to the treatment of the chassis of the vehicle. .
- the invention also proposes to greatly reduce the cost of treating vehicle parts, in particular parts of intermediate size.
- the invention proposes a tool particularly well suited to a treatment using a liquid bath, for example a paint treatment or an electrolytic treatment, and in particular a cataphoresis painting treatment.
- the subject of the invention is a support for parts to be surface-treated for a vehicle equipped with a chassis, which support comprises means for securing the parts in translation with the support, at least one means for electrically connecting at least one part with the support, means for electrically connecting the support with a electrode, the two electrical connection means being electrically connected to each other.
- the support comprises at least one means for mechanically fastening the support to the chassis of the vehicle.
- the support comprises means for mechanical fixing of each piece on the support, for example offering a contact surface between each piece and the support less than 10%, and preferably less than 1% of the surface of said piece. and distributed over at most ten and preferably at most four distinct zones
- the mechanical fastening means may also include a means of electrical connection of the part to the support.
- the support equipped with the parts to be treated, advantageously has an overall external volume that can be introduced inside said body.
- the contact surface between the support and the The vehicle chassis is located on the transmi sition tunnel, in the cai sse of the vehicle.
- the transmission tunnel of a vehicle is generally located in the direction of the length of the vehicle, and passes, in the body, between the locations of the seats.
- the support of the invention has a contact surface with the body distributed in at least two contact areas at least 10% apart, and preferably at least 50% of the large dimension of the parts to be painted. It is conceivable that such a support then has a seat on the transmission tunnel large enough to withstand the efforts that the liquid exerts on the parts to be painted. This characteristic is particularly important in the case of generally flat parts, treated by cataphoresis. Indeed, when such parts enter the cataphoresis bath, there is a "spoon effect" which means that as long as the pieces are not not completely immersed inside the bath, they tend to float above this bath. If the seat provided by the means for fixing the support to the chassis of the vehicle is insufficient, the support and the parts that it contains are torn off when the parts come into contact with the surface of the bath.
- the entire support is made of a material that withstands a temperature of between 20 ° C. and 200 ° C.
- the means for fixing the parts on the support can be provided with parts of low thermal inertia. intended to be manipulated. This makes it possible to use the support for the cooking phase following the cataphoresis treatment.

- a front bracket 17 and a rear bracket 18 each comprise a vertical portion 19, respectively 20 fixed to the left end of the arm respectively front and rear, and also comprise a horizontal portion 21, respectively 22 horizontal and parallel to the spar.
- a front inclined bracket 23 and a rear inclined bracket 24 each comprise a fixed portion 25, respectively 26 attached to the respective front and rear arms and inclined to each other in the direction of the top of the post respectively front and rear. a part 27, respectively 28, perpendicular to the inclined parts, and parallel to the axis of the spar 1.
- the inclined brackets 23 and 24 are each equipped with a lateral stop 31 and 32. The same applies to the brackets 21 and 22. Each of the lateral stops rising perpendicularly to the brackets, and parallel to the parts fixed on the arms.
- each of the brackets 17, 18, 23, 24 is equipped with a contact abutment 33, 34, 35, 36 respectively.
- the contact abutments 33, 35, 36 each have a bearing surface 37, 39, 40. The same is true of the contact abutment 34.
- a front sole 41 and a rear sole 42 are fixed on the top of the pole respectively front and rear.
- the front flange 41 has a vertical portion 43 extending downward and parallel to the front post 7. It also has an inclined portion 44 extending to the right of the post towards the fixed portion 25 of the angled bracket 23.

- the rear leg 16 is introduced into a slot 70 (visible in FIG. 3) of the transmission tunnel, so that the horizontal portion 16a is in contact with the lower wall 58 of the transmission tunnel.
- the entire support is therefore fixed by three contact zones on the transmission tunnel.
- the portion 16a of the rear leg 16 and the portion 60a of the elongate member 60 are in contact with the lower surface 58 of the transmission tunnel while the lower portion 15a of the cylindrical spacer 15 is in contact with the upper portion 62.
- the upper part of the transmission tunnel 62 is almost completely clear and can be treated by cataphoresis without being hindered by the presence of the support.
- Handles 63, 64, 65, 66 are screwed inside the abutments 47, 33, 49 and 35, respectively, through the workpieces 55 and 56.
- the contact surfaces 63a, 64a, 65a and 66a handles with the parts to be treated have been minimized and correspond to surfaces that will not be treated and that will have to be retouched later or masked, for example by a plastic cap.
- the contact surfaces 51, 37, 53 and 39 have also been minimized for the same reason. El also provide the function of electrical contact between the support and the workpieces 55 and 56.
- the handles 63, 64, 65, 66 are made of material with low thermal inertia, such as plastic, which allows the operator to be able to easily dismount parts as soon as the vehicle equipped with the support and the parts to be treated comes out of the stage of which it is usually in the neighborhood of 180 °. Similar handles make it possible to fix the parts to be painted 55 and 56 on the brackets 18 and 24, on the right part 45, and on the inclined part 46.
