Description

FULL SUPPORT

The utility model relates to the field of metalworking, namely to technological equipment for maintaining workpieces in working position when processing them on metal cutting machines.

Known approach support O: m. A.S.N 1796403 MKI B23Q 3/00: 1993), in the housing of which there are vertical plungers connected to the drive bolt through wedge inserts and intermediate elements mounted with the possibility of axial movement.

The disadvantage of this device is:

- high costs of auxiliary time for fixing the workpiece due to the sequential supply of plungers and a multi-link kinematic chain;

-the ability to squeeze the workpiece from its working position due to the large forces developed by threaded and wedge pairs;

- this design can contain only four input supports, no more and no less;

- The supported supports are not fixed from falling out or from turning around its axis.

The technical problem to which the utility model is aimed is to reduce the auxiliary time for securing the workpiece, expanding the technological capabilities of using the support block, eliminating the possibility of squeezing the workpiece from the working support ;-), increasing the reliability of the supplied supports,

The means of achieving the technical result consists in the fact that vertical plungers are placed in the device’s body, which are connected to the handle that drives the mechanism through axially mounted wedge inserts and intermediate elements made in the form of a spring-loaded rod fixed in wedge inserts with rigidly fixed to it

stops, while 1 line inserts are also spring-loaded with the ability to move along the bar independently of each other, and vertical plungers are spring-loaded relative to the wedge surfaces of the inserts

The proposed utility model is illustrated by drawings, where:

On Fig shows a General view of the device in section.

Figure 2 is a view a in Figure L.

The feed support block comprises a housing 1, with vertical plungers 2 mounted therein with the possibility of movement, which in turn are spring-loaded with elastic elements 3, which ensure fixation in the housing and constant contact of vertical plungers with corresponding wedge inserts 4, Wedge inserts spring-loaded with elastic elements 5 are made of the possibility of axial movement along the tongue 6, on which the stops 7 are rigidly fixed. The rod, in turn, is spring-loaded relative to the housing by the elastic element 8 with the help of pa 9 for protection against rotation on vertical plungers formed flats, which are wedge inserts in the slots, and for determining a fixed position on the handle 10 are included in the dihedron groove cover 11 connected with the housing,

The device operates as follows. In the initial position, the handle 10 is removed from the groove of the lid of Ni and is rotated 90 °, the elastic element 8 is compressed. Wedge inserts 4 by means of stops 1 are taken to the left, vertical plungers 2 are omitted.

When the handle 10 is rotated through 90, the elastic element 8 is unclenched and moves the rod 6 with stops 7 to the right, the handle 10 enters the groove and abuts against it. The wedge inserts 4, moving independently of each other by means of elastic elements 5 along the bar 14, press the vertical plungers 2 until the latter contact the surface of the workpiece 12 and wedge them by means of a self-braking angle.

of which position. The force of the elastic element 8 is selected so that in the working state it would exceed the sum of the efforts of the elastic elements 5 but at the same time it would be acceptable for hand compression of the worker.

The proposed device can significantly reduce the auxiliary time for fixing the workpiece, which leads to a reduction in the cost of the finished product. In addition, after calculating the force dependences, the proposed design allows to completely eliminate the possibility of squeezing the workpiece from its working position. The proposed block of supports allows you to apply different required (from two or more) the number of supplied supports. Differs in simplicity of design, speed and reliability.

Claims (1)

The block of supporting supports, in the case of which there are vertical plungers connected to the handle that drives the mechanism through axially mounted wedge inserts and intermediate elements, characterized in that the intermediate elements are made in the form of a spring-loaded rod mounted in the wedge inserts with a rigidly fixed stops, while the wedge inserts are also spring-loaded with the ability to move along the bar independently of each other, and the vertical plungers are spring-loaded relative On the wedge surfaces of the inserts.
