Abstract

The invention relates to instrumentation and can be used to fasten devices of both wafer and flange types. The purpose of the invention, the expansion of the scope and reliability, is achieved by the fact that the device for fixing the device 4, comprising a housing 1 and a split ring 2 with petals 5 on one of its highlanders and with a fixing screw 9, is provided with additional fixing screws 3, while the other end of the ring 2 is made associated with additional petals 5. 5 ill.

Description

rig 5

The invention relates to the field of instrumentation and can be used in various industries for securing devices with both a flange and a waferless body.

The purpose of the invention is to expand the scope of application by securing the devices of the flange and wafer type and increasing reliability by adjusting the fixing force.

Figure 1 shows a general view of a device for fixing a device; in Fig.2 - a split ring; Fig. 3 is a view A in Fig. 2; Fig. 4 shows the device in the adjustment position of the fixed device; figure 5 is a top view of the device with a fixed device.

The device for fixing the device comprises a housing 1 with a cylindrical hole in which the device 4 is fixed by means of a split ring 2 and additional fixing screws 3. The ring 2 has two rows of elastic petals 5, the free ends of which are angled to the housing of the device 4 with the possibility of interaction with the last when moving the screws 3. The screw 3 is made stepwise, while its threaded part interacts with the threaded hole of the housing 1, made perpendicular to the axis of the device 4, and with a smaller diameter with s the other groove b of the ring 2, which is perpendicular to the radius of the circle of the ring. The screw 3 ends with an axial displacement stop 7. A stop element 8 is placed on the threaded part of the screw 3. The ring 2 carries the main fixing screw 9 ...

The device operates as follows.

Before installing the device 4 (Fig. 5) with a fixing screw 9, as well as additional fixing screws 3,

establish the position of the elastic petals 5, in which the diameter of the geometric circle described by the free ends of the petals exceeds the diameter

the housing of the fixed device 4, after which the device 4 is installed at the required depth in the hole formed by the petals and in the hole of the housing 1 (Fig. 1).

Screwing screws 3, change the diameter

rings 2, while the elastic petals 5, facing the free ends to the body of the device 4, when interacting with it, change the angle of inclination, increasing the contact area and allowing mechanical fastening of the device 4 (Fig. 1).

The presence of axial movement stops 7, 8 on the screws 3 eliminates the destruction of the ring 2 and the device body 4. To dismantle the device 4, it is necessary to unscrew the screws 3 by several turns, while the axial movement limiter 7 interacts with the case of the split ring 2, and the free ends of the petals 5 increase ring diameter to size,

allowing you to remove the device from the device.

To ensure that the device moves parallel to the plane of the body, which is necessary, for example, when adjusting

optoelectronic sensors, unscrewing one of the turns 3 and screwing in the other two (Fig. 4) ensure the movement of the device in order to ensure the best functioning of the product as a whole.

Supply of the device for securing the device with additional fixing screws, and the other end of its split ring with associated petals,

as well as the installation of additional screws with the possibility of interacting with a split ring and with the housing of the device allowed to expand the scope and increase the reliability of the latter.
