Description

The technical field to which the utility model relates.

The utility model relates to technological equipment for the production of electrical products, in particular, to equipment for the manufacture of wiring harnesses.

State of the art

Currently, plaits with non-standard pins or forks are usually used in harness production. The disadvantages of this solution include the complexity of preparing the plaza, i.e. its readjustment, to release of new products. As a result, after use, such a plasm must be stored, and a new plasm should be prepared for new products.

The use of typical clamps for laying out bundles, for example, of Panduit, speeds up the folding process, but, as before, the complexity of preparing the plaza remains high, because typical clamps have to be fastened with screws or screws, and in addition, it is necessary to align the clamps of various sizes in height.

Perforated plazas are used, the clamps of which are mounted on screws. The manufacture of perforated panels is very time-consuming, and to increase the rigidity of the panel you have to install and fasten it to the crate. The manufacture of such a plaz turns out to be quite expensive compared to, for example, a plywood plaz. The complexity of preparing a perforated plaza is somewhat reduced due to the available holes. However, if you place a drawing on the plasma, then access to the holes will be difficult.

The prior art device for the manufacture of wire harnesses containing a panel with holes, pneumatic cylinders with pistons and stud rods mounted coaxially with the panel openings and connected pneumatic channels to the pneumatic system. Depending on the required configuration of the harness, upon command from the control unit, the corresponding stud rods extend upward relative to the surface of the panel. (SU 928688, publ. 05/15/1982).

The disadvantage of the above device is the complexity of its manufacture and, accordingly, the high cost.

Another comprehensive but extremely costly solution is an assembly table with an interactive assembly plaz. This is a fully computerized equipment that displays on a large flat screen a prepared drawing and a layout program for the harness. The advantage of the system is that it practically does not allow the operator to make a mistake. The program provides step-by-step operator guidance during assembly of the harness with control of incoming wires by barcode.

This equipment also uses standard Panduit clamps, turns and splitters, which are mounted on the mounting table by means of vacuum suction cups. https: //www.voutube.corn/watch? v = UCgg-HnsWsU of November 23, 2014

The disadvantages of the system used include the high cost, high cost and cumbersomeness of the vacuum clamp fasteners, as well as the need to use an absolutely smooth surface (glass) for installing the vacuum fasteners. But even in this case, after a few days, the depth of the vacuum gradually decreases and the heavy vacuum stand spontaneously “sticks” to its intended place.

Utility Model Disclosure

The objective of the utility model is the creation of equipment for the manufacture of wire harnesses, in particular, a plaza that provides quick and accurate preparation of the plaza for the layout of the harness, the ability to quickly and reliably fasten the wire holders at any point on the assembly table, ensuring their long and reliable fixation.

The problem is solved in that the plasma for the manufacture of wire harnesses is made in the form of an assembly table with wire holders attached to it, intended for clamping wires, turning wires or a bundle of wires, as well as branching wires. The wire holders are made magnetic, while the mounting table is covered with sheet magnetic material.

The above tasks are solved by performing magnetic wire holders.

Brief Description of the Drawings

The utility model is illustrated by drawings, in which:

in FIG. 1 shows a general view of a plaza for the manufacture of wire harnesses with magnetic wire holders;

in FIG. 2 - magnetic holder of wires with a clip;

in FIG. 3-magnetic wire holder for turning a wire or bundle of wires;

in FIG. 4 - magnetic holder of wires for branching wires.

Utility Model Implementation

As shown in FIG. 1, the workstation (plasma) for the manufacture of wire harnesses is an assembly table 1. The working surface of the assembly table 1 can be formed by a solid steel sheet, painted or perforated. On plywood, wooden or non-magnetic tables can be fixed sheet coatings made of any magnetic material, for example, steel, galvanized steel, stainless steel of the respective grades.

On the mounting table 1, magnetic holders of 2 wires with clamps, magnetic holders 3 for turning a wire or bundle of wires, magnetic holders 4 for branching wires, magnetic holders 5 with small clamps can be fixed. The number, type of magnetic holders and their position on the mounting table is determined by the required configuration of the 6-wire harness.

In FIG. 2 shows a magnetic holder for 2 wires with a clip for wires. The magnetic holder 2 comprises a base 7 on which two permanent magnets 9 and a clamp 10 for holding the wires 11 are fixed using fasteners 8.

In FIG. 3 shows a magnetic holder of 3 wires for turning wires. The magnetic holder 3 comprises a base 12 on which a permanent magnet 14 and a pivoting mandrel 15 are fixed using fasteners 13.

In FIG. 4 shows a magnetic holder of 4 wires for branching the wires. The magnetic holder 4 comprises a base 16 on which a permanent magnet 17 is fixed and pins 18 are installed for branching the wires 11.

The number of permanent magnets on the magnetic wire holder is determined by the necessary force to detach the holder from the magnetic material of the mounting table, the shear force and the turning moment. The choice of the shape and size of the base of the holders allows you to compensate for the difference in height of the used clamps, rotary mandrels and pins.

If necessary, the line of working elements on magnetic wire holders can be expanded. Additionally, combs can be installed for orderly securing the ends of the wire harness, as well as fasteners of various connectors for their desoldering.

Placing the magnetic holders of 2-5 wires on the desktop 1 in the right places is carried out in one of two ways:

- fixing the sheet with the drawing of the bundle in a 1: 1 scale by pressing it by the magnetic wire holders themselves;

- transferring the drawing of the tourniquet to the plasma by marking it with colored markers, followed by the placement of the necessary magnetic holders on the plasma.

The advantage of magnetic wire holders over known designs is as follows:

- quick preparation of the plaza for the layout of a new tourniquet;

- magnetic wire holders can be fixed at any point on the installation table and rotated to any desired angle even during preparation for the layout and when adjusting the position when laying out the bundle;

- there are no costs for the development and manufacture of home-made fasteners;

- reduced costs for additional new plazas and their storage;

- the possibility of using inexpensive and rigid materials for the assembly table without perforation;

- lower price in comparison with vacuum holders;

- the absence of the effect of spontaneous "detachment" of magnetic wire holders even on inclined mounting tables;

- versatility for almost all types of harnesses.

Thus, the use of magnetic wire holders solves the following production problems:

- universalization of the used equipment;

- acceleration of operations on the layout of harnesses (increased productivity);

- reduction of the nomenclature and universalization of equipment;

- acceleration and cost reduction during the transition from one type of product to another (cost reduction for preparatory and final operations);

- replacement of unique operations with standard ones;

- reduction in the types of equipment used;

- reduction of production and storage facilities;

- minimize the occurrence of intermediate organizational tasks.
