Kiss-coating is needed when being screwed into screw hole 54, head of screw outer end face is lower than chock plug periphery.
As shown in Fig. 1,5,6, the rear plug mechanism of the utility model includes rear plug 80 and artillery cleaning staff 90, and rear plug 80 is envelope
Plug is closed, is screwed onto the open rearward end of outer cylinder 10, artillery cleaning staff 90 is screwed on the internal thread hole of rear plug 80, different-diameter
The mounting portion that identical external screw thread size is all had on artillery cleaning staff 90 guarantees the mountable various sizes of artillery cleaning staff on rear plug 80.Such as
Fig. 5, shown in 6, the bristle 91 of artillery cleaning staff 90 in the shape of a spiral, spiral helicine bristle 91 can by vibration straight line move forward and backward conversion
It is moved forward and backward for what is rotated in vibration.
The working principle of the utility model are as follows: push chock plug former in the work of short stroke impact vibration using compressed gas
Reason, the front and back gas vent collective effect on hole and outer cylinder that gas passes through hollow shaft on chock plug, gas push chock plug is in outer cylinder
Vibration drives entire bore cleaning machine to move forward or back；90 upper bristle 91 of artillery cleaning staff, can band in bore cleaning machine vibration using spiral arrangement
Movement machine rotation, bore cleaning machine pneumatic in this way can be rotated in gun tube inner edge, side vibration moves forward or back and completes to wipe thorax task.
As shown in Figure 7,8, the specifically used method of the utility model are as follows:
Before operation, chock plug 50, is slid into the front end of outer cylinder 10 by the rear end for lifting bore cleaning machine, and chock plug 50 blocks front row
Stomata 11 and deblocking heel row stomata 12, i.e., position shown in Fig. 7；Then, air compressor is connected by tracheae with gas source connector
It connects；
When work, bore cleaning machine is put at bore mouth, opens air compressor, gas is through gas source connector 30, guiding axis 40
Blind hole 41, the venthole 42 of guiding axis 40, gas circuit (inner wall of annular groove 43 and chock plug centre bore 56 is formed by gas circuit),
13 He of front chamber that steel ball 70 rotates and premenstrual hollow shaft 60 and rear hollow shaft 61 enter outer cylinder 10 respectively is blown after connecting hole 51
Rear chamber 14, since front chamber 13 is closed in this case, and rear chamber 14 is even open to atmosphere；Therefore, with gas
Entrance, the air pressure of front chamber is greater than the air pressure (air pressure that the air pressure of 70 front end of steel ball is greater than rear end) of rear chamber, to push
Steel ball 70 blocks the front end of rear hollow shaft 61, so that gas is flow to front chamber 13 from the hole of preceding hollow shaft 60 completely, is formed backward
Active force pushes chock plug 50 to move backward；
Chock plug 50 moves to when blocking heel row stomata 12 and unsealing front-seat stomata 11 (state as shown in Figure 8), rear chamber
14 be closed in this case, and front chamber 13 is that company is open to atmosphere, and chock plug 50 continues to move pressure backward under effect of inertia
The air of contracting rear chamber 14, make rear chamber 14 air pressure be greater than front chamber 13 air pressure (air pressure of 70 rear end of steel ball be greater than front end
Air pressure), steel ball 70 block before hollow shaft 60 rear end, thus make gas from the hole of rear hollow shaft 61 flow to rear chamber 14 and fill in
First 50 continue to move backward under effect of inertia, drive bore cleaning machine to move backward in bore by 14 air pressure of rear chamber；Work as plug
First 50 when moving to rear 80 position of plug, and chock plug 50 travels forward under the reaction of rear chamber's air pressure, when chock plug 50 moves to
When blocking front-seat stomata 11 and deblocking heel row stomata 12 (state as shown in Figure 7), the air pressure of front chamber 13 is greater than rear chamber 14
Air pressure, steel ball 70 blocks rear hollow shaft 61, gas made to flow to front chamber 13 and chock plug 50 in inertia from the hole of preceding hollow shaft 60
It moves forward under effect, the speed that bore cleaning machine moves backward in bore is reduced by front chamber's air pressure, but not drive
Bore cleaning machine travels forward；
Moving forward and backward for above-mentioned chock plug 50 drives bore cleaning machine to move backward in bore, and the artillery cleaning staff of brush head will be wiped in the shape of a spiral
The moved straight rearward of thorax machine is converted into rotation and moves backward, clears up bore；
When artillery cleaning staff moves to bore rearmost end, it is pulled along tracheae, the forward active force of chock plug is given, makes the initial of bore cleaning machine
The direction of motion is to travel forward, and moving forward and backward for chock plug drives bore cleaning machine to travel forward in bore, and bore cleaning machine exits bore；Its
Principle is consistent with the principle that bore moves backward.It operates repeatedly, bore cleaning machine moves back and forth in bore, until bore is cleared up
Until clean satisfaction.
The artillery cleaning staff 90 of replacement different-diameter may be implemented to brush the different small-bore various types gun tubes of 25~120mm (as prevented
Defend big gun, warship canon, rocket gun etc.) obstinate attachment, coppering, the gunpowder residue, grease of interior thorax.Bristle on artillery cleaning staff 90 uses spiral
Formula arrangement, and then formation is along the power of the bristle hand of spiral in machine vibration, band movement machine rotation, bore cleaning machine pneumatic in this way can
It is moved forward or back in the rotation of gun tube inner edge, side vibration and completes to wipe thorax task.
The utility model uses modularized design, easy to operate, and maintenance is simple.Use compressed air for power source (5-
The vehicle tire inflation systems such as administrative vehicle or panzer 8Kg) can be used.It can be supplied simultaneously in air compressor or room air
Should stand upper use.Rotation is driven using gas source vibration, spiral arrangement bristle, realize pneumatic bore cleaning machine rotate in gun tube inner edge,
Side vibration, which moves forward or back, to be completed to wipe thorax task.Small in size: length 130mm diameter 23mm, light-weight: (comparison is domestic and international by 1.5Kg
Other product minimum length 180mm diameter 46mm weight: 3.5Kg), can be vehicle-mounted, portable, individual soldier can operate.It is small in Rapid Cleaning
Bore smooth bore big gun gun tube (3-6m/min).The replaceable design of artillery cleaning staff, the more multi-sizes of artillery cleaning staff (personalized), a dress
Standby replacement different size artillery cleaning staff can realize the function of cleaning different bore gun tubes (25-120mm), and be applicable in various types gun tube
(such as defence big gun, warship canon, rocket gun etc.), pneumatic actuation operation, Applicable temperature range is wide, Applicable temperature: -40 DEG C -+65 DEG C.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
