Embodiment 1

[0021] like figure 1 with Image 6 As shown, an inner hole seal mounting device includes a body mandrel and a coupling piece 1 inserted with the body mandrel.

[0022] The body mandrel is provided with a guide groove 5 in the axial direction, and the body core shaft includes a limiting shaft 2 and a socket shaft 3 having a cylindrical step axis, the front end diameter of the limiting axis 2 Small than the rear end diameter, the plug shaft 3 is a hologram structure having a rear pressure ring 31 and a front pressure ring 32 having a diameter of the same diameter, and the intermediate is connected by a connecting piece 33, the front end surface of the rear pressure ring 31 and A curved transition is used at the front end corner of the front pressure ring 32, the rear pressure ring 31 fixed to the front end surface of the connection limit shaft 2, the rear pressure ring 31 diameter is less than the front end diameter of the limit shaft 2, the limit shaft 2 And inserted shaft 3 integra...

Embodiment 2

[0028] like Figure 7 As shown, the present embodiment differs from the first embodiment in that the front end side of the coupling shaft 3 is disposed to face two sets of first recessed grooves 34; the front end side wall is symmetrically provided with two groups. The second groove 12. When using, two seals can be installed at the same time.

Abstract

The invention discloses an inner hole sealing ring installation device, which comprises a main body mandrel and a plug-in piece plugged with the main body mandrel; shaft and plug-in shaft, the plug-in shaft is an I-shaped structure, the two ends of which are the rear pressure ring and the front pressure ring with the same diameter, and the middle is connected by a connecting piece, and the rear pressure ring is fixedly connected to the limit shaft. The side of the front end of the connecting piece is symmetrically provided with multiple groups of first grooves; the side wall of the front end of the plug-in piece is symmetrically provided with multiple groups of second grooves, the plug-in piece is inserted into the guide groove of the mandrel of the main body, and the plug-in The sheet is movable relative to the main body mandrel. The invention has simple structure and convenient operation, is suitable for the installation of small-diameter deep-hole sealing rings, and can realize the simultaneous installation of a plurality of continuous sealing rings in the deep holes.

Description

Technical field [0001] The present invention relates to the technical field of mechanical tools, and more particularly to an inner hole seal mounting device. Background technique [0002] At present, the inner hole seal is installed, mainly including the following installation: 1) Place the sealing ring on the sealing slot side, blow to the sealed slot; 2) The mechanism hooks the side of the rubber ring and explores it in the hole. The agency reply, the specific structure rotates, and the rubber circle is rotated into the sealing tank; Rotate the robot and feed the seal into the sealing tank; 4) screw the rubber ring into the sealing trough by the lead screw. The current mounting mechanism and installation are suitable for large diameters (diameter> 20 mm) sealing rings such as cylinder cylinders, which are not applicable to the relatively small lines of diameters, and the inner hole seal is installed. Because the pipeline diameter is small (diameter ≤ 20 mm), the retracting r...
