Abstract

This invention relates to a test " technique. The purpose of the invention is to increase the reliability and durability of the device. It comprises a housing (K) 1 with a sealing element 2 and a fitting 4 for supplying a liquid. Placed in K 1 is the lead screw 5, on which the suspension (P) 9 is installed, and clamping cams 11 rotating in the plane passing through the common axis K 1 and P 9 and interacting with them. Through screw 5 on its axis passes pn (L with SP SP 00 CX) grue.f //

Description

axis 16, and on the end of the axis on the side of P9 there is fixed a cam disc 18 with through curvilinear grooves. The cams 11 are made with fingers inserted into the slots and notches 15, the latter provide the possibility of radial translational movement of the cams 11 in the plane of their rotation. P 9 is made with a cavity filled with hydroplastic s and pushers in the form of plungers 21, each of which is one

 The invention relates to a testing technique and can be used to test hollow articles having an internal flange or shoulder for, for example, tanks with hatches or throats, excessive pressure of the medium.

The purpose of the invention is to increase the reliability and durability of the device.

Fig, 1 shows the device a general view; in fig. 2 - the same, bottom view, from the side of the copier disk,

A device for sealing hollow articles comprises a housing 1 with a sealing element 2, a channel 3 for supplying a liquid to the sealing element 2 and a fitting 4 for supplying liquid from an external source (not shown), housed screw 5 with a handle 6 in housing 1 in the bearing 7, a suspension 9 is installed in the bearing 7 by means of a stop nut, fixed from rotation relative to the housing 1 by stops 10, clamping cams 11 mounted on the axles 12 in the brackets 13 of the housing 1 rotatably in a plane passing through the common axis of the housing 1 and the bottom Ski 9, interacting with them and having fingers 14 and notches 15, providing the possibility of radial translational movement of the cams 11 in the plane of their rotation, a rotary axis 16 having a handle 17 and passing through the lead screw 5 along its axis and fixed on the end ( not shown) axis 16 on the suspension side 9 a cam disc 18 with through curvilinear grooves 19, which include the fingers 14 of the cams IK The suspension 9 is made with a cavity (does not enter into the cavity P 9, but not against the cams 11. Rotate the screw 5 Cams 11 turn, etc. Izhima them to the product from the inside, and K 1 - to the product from the outside. The uniformity of the clamp K 1 to the product is ensured by equalizing the clamping forces on the cams 1 1. Through the nozzle 4 under pressure, fluid is supplied, which flows into the cavity of the product and to the element 2, pressing it against K 1 and the product, 2 Il.

Started), filled with hydroplastics

20, and with plunger pushers

21, each of which at one end (not labeled) enters the cavity of the suspension 9, and the other abuts against the clamping jaws 11.

The connection of the lead screw 5 with the housing 1 is sealed by rings 22, and with axis 16 by rings 23, axis 16 is protected by ring 24 from vertical movements,

The device works as follows.

The housing 1 is mounted on the product 25, while the cams 11 are collapsed (shown by dash-dotted lines) and not left behind. the size of the opening (not indicated) of product 25, and the suspension 9 is in the uppermost position (in FIG. 1). The knob 17 rotates the axis 16 together with the cam disc -18, while the fingers 14 of the cams 11 slide along the grooves 19 of the copier disc 18 and the cams 11 progressively move in the radial direction due to the presence of notches 15, beyond the dimensions of the product 25. With the screw 6, the lead screw 5 is rotated, the suspension 9 moves downwards (as shown in FIG. 1) and its plungers 21 abut against the cams 11 and, with further rotation of the screw screw 5, turn the cams 11 on the axes 12, pressing them against the product 25 from the inside, and the housing 1 to item 25 outside. The uniformity of clamping the housing 1 to the product 25 is ensured by equalizing the pressing forces on the cams 11 through the plungers 21 and the hydroplastic 20,.

Through the nozzle 4, pressurized fluid is supplied, which enters the cavity (not shown) of article 25 and the n channels 3 to the sealing element 2; clamping it to the housing 1 and product 25.. .

Dismantling the device is carried out in

reverse sequence.
