DE102008016102A1 - Device for manufacturing undercut grooves for almond-shaped connection elements or lamellae for component connector, has support which is assigned to another support with parameters of latch height at tools - Google Patents

Abstract

The device (4) has a support (5), which is assigned to another support (6) with parameters of a latch height (h) at tools for manufacturing almond-shaped grooves in distant manner. The latter support has a pin (7), which is guided through an attachment (9) of the former support.

Description

The The invention relates to a device for producing undercut Grooves for Component connector with spring for the locking connection of components made of milling Materials.

devices for the production of grooves for wooden slats, especially almond-shaped Slats are already longer known. However, not known are devices for slats with springs, as they require undercut grooves.

task The present invention is to provide a device which allows such undercut grooves for almond-shaped Manufacture lamellas.

The The object of the invention is achieved in that known tools be modified for the production of lamellae so that a Both sides undercutting a groove is possible.

The Production of a known groove is usually done so that a Edition, which is part of the saw or milling tool is, in height adjustable to the tool is placed on the workpiece and the tool by hand Feed is retracted into the workpiece up to the preset groove depth becomes.

The inventive modification for the production undercut grooves now takes place so that the first existing Edition another plate is assigned as a second edition, in such a way that between the first and second edition a distance is set as he is the height a latching nose at a connecting element resp. a lamella corresponds. The second edition is at least one attached to her cylindrical Spigot through at least one cylindrical attachment on the opposite side the first edition. More cones and attachments to the leadership However, the strokes are provided.

In a preferred embodiment are the at least one pin and an attachment in a middle Narrows the area so that above and below ring surfaces arise, which limit the spigot stroke accordingly. The respective lower and upper travel must be there each corresponding to a latching nose height. The constricted area is preferably centered at least one indexing (bullet) assigned, so that a noticeable locking center position of the pin in the essay results. A statement to secure the detent position can be provided to an adjustment while the milling the groove to the inlet depth to prevent.

To made incision of a groove as described above, the pin can each against the ring surfaces so that, assuming a suitable tool, produce undercut grooves.

For different Thickness of connecting elements and / or different locking lugs are at least the narrowed area of the pin and the essay adapt.

at a preferred embodiment the constricted portion of the essay is performed as a ring, the in height the indexing by grub screws or the like is mounted and that is interchangeable. Leave different upper and lower travel paths in addition by sliding rings in the narrowed area of the pin make. For this must this then be designed accordingly long. That's the way it will be even with appropriate tools possible "top" and "bottom" different undercuts to reach a groove. The Nuthinterschneidungen then done by Pull resp. To press the pin either directly or articulated.

at another version for stroke adjustment of a second edition are pin and attachment designed as a threaded or spindle drive, so that a rotational rotation a peg or a nut to the left and right the corresponding Undercuts in a groove cause. The angles of rotation can be light through - too changeable - limit stops Such a device can be advantageous for stationary Facilities, so for use standardized mass production if the threading or spindle drive motor, preferably by a stepper motor, is adjusted.

The The invention will be further explained with reference to the accompanying drawings.
