Drawings
Fig. 1 is a schematic structural diagram of a gun barrel connecting device in a gun barrel connecting device of a Hopkinson pressure bar experiment system.
In the figure, a first pipe 1, a second gun barrel 2, a clamping ring sleeve 3, a clamping ring 4, a connecting sleeve 5 and a fastening screw 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, rather than all embodiments.
As shown in fig. 1, a gun barrel connecting device of a hopkinson pressure bar experiment system comprises a gun barrel 1, a gun barrel 2, a clamping ring sleeve 3, a clamping ring 4, a connecting sleeve 5 and a fastening screw 6, wherein the gun barrel 1 is fixedly connected with the gun barrel 2 through the connecting sleeve 5, the clamping ring sleeve 3 is respectively arranged on the gun barrel 1 and the gun barrel 2, the clamping rings 4 are respectively arranged in annular grooves of two pipe ends of the gun barrel 1 and the gun barrel 2 and between the clamping ring sleeve 3 and used for keeping the annular groove inclined surfaces on the gun barrel corresponding to the clamping ring inclined surfaces and enabling the clamping ring sleeve 3 to be clamped on the clamping ring 4, stepped circular pipe end connecting holes are respectively arranged in two middle holes of the connecting sleeve 5, the two clamping ring sleeves 3 are fastened and connected through the fastening screw 6 of the connecting holes in the clamping ring sleeves 3 at two ends, the clamping ring sleeves 3 at two ends are circumferentially fastened on the gun barrel 5, opposite threads are forced to radially contract towards a core part in the clamping ring sleeves 3 and compress through opposite direction connecting sleeve 5, and the gun barrel is attached through the connecting sleeve 5.
The working principle is as follows: the connecting ring grooves with inclined planes at the end parts of two gun tubes with the same specification are matched with the clamping rings 4 through the clamping ring sleeves 2, and then the gun tubes are oppositely installed by using the self-centering alignment principle, and are connected and fixed to the connecting sleeve 5 between the two gun tubes through the fastening screws 6, so that the structural device for reliably connecting the two gun tubes of the test system is realized.
The specific implementation is as follows: the method comprises the steps of respectively penetrating a snap ring sleeve 3 into the ends of two gun barrels I1 and II 2 in an opposite mode, respectively placing an open type snap ring 4 into annular grooves at the ends of the two gun barrels, keeping the inclined plane of the annular groove on the gun barrel corresponding to the inclined plane of the snap ring, respectively moving the snap ring sleeve 3 to hoop the snap ring 4, respectively filling stepped circles at the ends of the two pipes into a middle hole of a connecting sleeve 5, filling a fastening screw 6 into a connecting hole in the snap ring sleeve 2 at the two ends, circumferentially fastening the snap ring sleeve 2 at the two ends to the connecting sleeve 5, oppositely fastening and stressing through threads at the two sides to force the snap rings 4 at the two sides to radially contract and compress towards a core part in the snap ring sleeve 3, and simultaneously enabling the two gun barrels to be oppositely attached through the connecting sleeve 5, so that the connection reliability of the two gun barrels can meet the system test application.
