Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the utility model automatic reciprocating band damped oscillation structural representation of air cylinder.
Refer to Fig. 1, the automatic reciprocating type band damped oscillation cylinder that the utility model provides, comprise master cylinder cylindrical shell 1, in described master cylinder cylindrical shell 1, two ends, left and right are equipped with main piston assembly 3, and described main piston assembly 3 is connected with rack member; Wherein, the cavity 2 that one comprises hydraulic damping chamber and selector valve is provided with below described master cylinder cylindrical shell 1, damping piston assembly is provided with in described cavity 2, described damping piston assembly is connected with rack member and reversing piston bar assembly, described master cylinder cylindrical shell 1 and cavity 2 run through and is provided with an output shaft 6, described output shaft 6 links together with the rack member on main piston assembly and damping piston assembly, and described output shaft 6 is provided with the central through bore for spraying cleaning solution.
The automatic reciprocating type band damped oscillation cylinder that the utility model provides, the rack member on described main piston assembly 3 comprises intermeshing master gear 4 and gear bar 5, and the two ends of described main piston assembly are provided with progressive switch S 1, S2 and beam 7.Rack member on described damping piston assembly comprises intermeshing damping gear 12 and damping tooth bar 16, and described damping gear 12 is located in damping cylinder barrel 13 with damping tooth bar 16, and is furnished with damping joint 15 and damped cylinder end cap 14, as shown in Figure 2.
Please continue see Fig. 1 and Fig. 3, the automatic reciprocating band damped oscillation cylinder operation that the utility model provides is run as follows:
1, output shaft rotates clockwise, (the row motion left of main piston assembly)
A, now source of the gas enter from P mouth selector valve to be entered master cylinder cylindrical shell 1 No. 4 mouths by passage, the main piston assembly promoting the right side moves left, gear bar 5 on main piston assembly 3 is simultaneously to left movement, gear bar 5 drives master gear 4 to rotate clockwise, output shaft 6 is then driven to rotate clockwise, gas now in left chamber, is discharged by E relief opening from No. 1 mouth through passage; When the left side piston on earth time contact beam 7(main piston assembly decrease impact), close to asymptotic switch S 2 on the piston assembly on the right side this moment, switch sends the electrical signal put in place, No. 3 mouths have also communicated with No. 4 mouths this moment simultaneously, the pressurized air of No. 4 mouths enters the right-hand member of change-over valve core bar 11 through passage through No. 3 mouths, by valve core rod 11 to left movement, the gas of valve core rod 11 left end, part is discharged from E relief opening through No. 1 mouth by No. 2 mouths, part is received by intermediate gear chamber, because the case lid etc. of intermediate gear chamber is not sealing, can receive.
B, due to after valve core rod 11 runs to the end left, the flow direction of gas in runner of valve inside has also changed, and mechanism will carry out rightabout operation.
2, output shaft rotates counterclockwise, (the row motion to the right of main piston assembly)
A, now source of the gas enter from P mouth selector valve to be entered master cylinder cylindrical shell 1 No. 1 mouth by passage, the main piston assembly promoting the left side moves right, gear bar 5 on main piston assembly moves right simultaneously, gear bar 5 drives master gear 4 to rotate counterclockwise, and drives output shaft 6 to rotate counterclockwise, gas now in right chamber, is discharged by E relief opening from No. 4 mouths through passage; When the right side piston on earth time contact beam 7(main piston assembly decrease impact), close to asymptotic switch S 1 on the piston assembly on the left side this moment, switch sends the electrical signal put in place, No. 1 mouth has also communicated with No. 2 mouths this moment simultaneously, the pressurized air of No. 1 mouth enters the left end of change-over valve core bar 11 through passage through No. 2 mouths, valve core rod 11 is moved right, the gas of valve core rod 11 right-hand member, part is discharged from E relief opening through No. 4 mouths by No. 3 mouths, part is received by intermediate gear chamber, because the case lid etc. of intermediate gear chamber is not sealing, can receive.
3, requirement out of service, output shaft is in neutral position
Ends A 11 and A12 control mouth air inlet to the left and right simultaneously, and two ends piston ejects to centre simultaneously, and main piston assembly and gear bar stop in neutral position, and output shaft 6 rests on neutral position.
4, requirement out of service, output shaft rotates to right position
Left end selector valve A controls mouth entering signal, unidirectional sheet rubber 8 air pressure to be moved right at piston mandril 10 by channeling and pushes valve core rod 11 to right-hand member, when right-hand member has pressurized air, the active area of left end is greater than right-hand member, valve core rod 11 remains at the position of right-hand member, mechanism stops reciprocating rotation, and output shaft 6 is still in right positions.
5, the explanation of miscellaneous function
A, W mouth be liquid by cylinder chamber inner flow passage, enter the central through bore of output shaft 11, can cleaning solution be sprayed at output terminal.
B, in order to make rotation time steady, master gear 4 and output shaft 6 connect as one, and output shaft 6 also connects a damping gear 12 simultaneously, and damping gear 12 engage connected with damping tooth bar 16.Parallel outside the chamber at main piston place also have a liquid container to have one group of rack piston assembly that can play damping function equally, to have in assembly through test move the constant throttling orifice reserved, one end liquid slowly can only flow to the other end at the uniform velocity stably from this constant throttling orifice when running, and rack piston assembly obtains steadily at the uniform velocity moving.Then output shaft 6 also steadily uniform rotation.
During the commutation of c, selector valve, changing is to the sports immunology of part
C1: left end selector valve A controls mouth entering signal, and unidirectional sheet rubber 8 air pressure to be moved right at piston mandril 10 by channeling and pushes valve core rod 11 to right-hand member;
C2: after selector valve A controls mouth loss signal, right side has pressurized air to promote valve core rod 11 to left movement, piston mandril 10 also to left movement, spiracle O
2ensure piston mandril 10 can move, the gas on the left of piston mandril 10 also can from valve seat 9 internal channel outflow by unidirectional sheet rubber 8 to left movement, gas from central through bore through runner from exhaust port O
1discharge, now piston mandril 10 keeps this state, and later mechanism reruns and do not involved (when changeover valve core can remain on the two ends arbitrary end of valve at ordinary times, mechanism also can back and forth normally run).
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
