CS248137B1 - Clamping fixture for fixation of objects - Google Patents

Abstract

The base plate (1) of the device has four fixed jacks (2) with guides (3), on which are inserted crossbars (8) consisting of discs (4), a crossbar (5) and a crossbar screw (6) with a crossbar (7), on which are inserted jaws (9). The catches (10) are screwed onto a longitudinal screw (11) provided with a spacer (12) and are placed in housings (13) connected to the base plate (1).

Description

The invention relates to a support clamping device and other fixed objects.

Up to now known fixtures of meh chairs and chairs. The tables are designed with clamping strips, which are pre-staivated in the longitudinal axis along the base plate and are fastened to it by a screwdriver. On the clamping strips, the carbon-shaped runners with backrests, which can be adjusted in the upright direction, are fixed to the clamping strips according to the ripped leg of the test or object. Another known table leg clamping device is mounted on fixed or movable platforms on which cross-leg supports are provided. The foot holder has a seat with protrusions and clamping elements which are terminated by an armrest.

The drawbacks of the described devices are mainly in the demanding positioning of the test item in the vertical axis of the mechanical test power unit and in the complicated fixing of each leg separately in the patient under the table or chair.

Said dioposial rolls of the known type removes the supercaptic clamping device for the fixed fixing of objects, which is based on the fact that on the base plate there are fixed on the sides of the blocks with firmly arranged water guides, which are made up of prongs which consist of While being connected by a transverse rod and a parallel transverse bolt to the mount, the jaws which can be presetitized in the transverse direction, the jaws in the longitudinal direction, are slid on the transverse rod and in the transverse islet, the screw is housed in bodies which are fixedly connected to the base plate.

The advantage of the support clamping device is, in particular, the simple clamping in the dositiredu alignment of the object to be tested, which consists in the uniformity of displacement of the functional parts from the central axis a, sleeping in the transverse and longitudinal directions using right-hand screws. The rigid positioning of the object and its co-axial alignment with the power unit are detected by the same work effect even in the case of a split, front and no leg separation. It is a diainé by the unification of the components of the two crossbars, each of which has a p-tail tail for the transverse pirestavemia of the jaws. The access to the control of the switchgear and the drives, which are situated outside the set-up area of the test item, facilitates the work of the operator in the preparation part for the mechanical strength test.

An exemplary arrangement of a super-fastening device according to the invention is shown in the drawing, where the plan view of the device is a fixed alignment of the pired materials.

The description of the device is mounted on the base plate 1, in which the cats 2 are fixed on the sides. The guides 3 on which the housings 4 are slid are fixed by dices 2, two. The transfer, with the other houses 4 of the transverse rod 5 and the preanium screw 6 with the drive 7, formed a single unit, so-called. crossbeam 8. Jaws 9 stored on. The crossbars 8 are inline and are applied to the guides 3 by means of catches 10 which are screwed onto the set screws 11 with the adjuster 12. The lateral screw 11 is housed in bodies 13 which are fixed to the base d-shank 1. as required against movement.

The functional operation of the support clamping device is subject to the required relevant methodology of mechanical tests of seating and table furniture. According to the r-stroke, the legs of the furniture sample to be tested, the transverse 8 displacements of the plunger 12 in the longitudinal direction and the center of gravity 9 are moved by the transverse directional movements 7 of the pirestavia so as to provide free space , sia found! from inside -noh. Then, by symchroinizing the intersection, the intrusions 12 and the thioes 7, the diodes of the diode are approached until the legs of the test specimen are equally fixed, rigidly fixed. The locks 4 and the ears 9 were secured with loosening bolts.

The sup-ortho clamping device is intended especially for fixing chairs, chair chairs and tables during their testing. It can be used in state testing, in the testing of the furniture in question and in in-house laboratories of control with the production of se-diaciehio and table furniture.
