Description
Technical field
The utility model relates to cylinder component device field, is specifically related to a kind of piston with buffer structure.
Background technique
In prior art, in order to control the piston rod extending amount of cylinder, a sheathed magnetosphere on piston usually, control magnetosphere by magnetosphere controller, thus know the extending amount of piston rod, but in the friction process of piston and cylinder body, wearing and tearing can be produced to magnetosphere, cause shorten working life; Piston lacks pooling feature in addition, easily shortens the working life of piston.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of piston with buffer structure, by changing the structure of piston, magnetosphere lining is adopted to protect magnetosphere, the object increased the service life can be played, mounting guide sleeve on secondary piston body and back piston body, can play buffering work use simultaneously, and is conveniently connected with piston rod.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of piston with buffer structure, comprise secondary piston body and back piston body, described secondary piston body and described back piston body are equipped with guide pin bushing, on described secondary piston body and described back piston body joint diametric plane on offer groove respectively, described secondary piston body offers the first breach, piston body offers the second breach in the rear, described first breach and described second breach are encircled into rectangle groove, at described rectangle groove built with upper and lower two magnetosphere linings, described magnetosphere lining tundish is covered with magnetosphere, U-shaped ring is fixed with in the periphery of described magnetosphere lining, described U-shaped ring is positioned at described groove.
Preferably, described first breach and described second breach are all offered along the bottom of described groove to the central direction of described secondary piston body.
Preferably, the guide pin bushing top of piston body offers shoulder hole in the rear, is fastened by the head of nut and piston rod.
By technique scheme, the utility model has the following advantages:
1, the area of contact of piston and piston rod can be increased by described guide pin bushing, the steadiness of connection can be strengthened;
2, by utilizing U-shaped ring to be fixed magnetosphere lining, avoiding the slotted eye offering other on piston, reducing difficulty of processing;
3, by utilizing magnetosphere lining to protect magnetosphere, magnetosphere can be avoided impaired.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of piston structure schematic diagram with buffer structure disclosed in the utility model embodiment.
Numeral and the corresponding part title represented by letter in figure:
1, secondary piston body; 2, back piston body; 3, guide pin bushing; 4, piston rod; 5, groove; 6, the first breach; 7, the second breach; 8, magnetosphere lining; 9, magnetosphere; 10, U-shaped ring; 11, nut.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, to the utility model, embodiment is described in detail.
As shown in Figure 1, a kind of piston with buffer structure, comprises secondary piston body 1 and back piston body 2, and described secondary piston body 1 and described back piston body 2 are equipped with guide pin bushing 3, can make piston rod 4 and described piston Joint by described guide pin bushing 3.
Described secondary piston body 1 and described back piston body 2 connect, on described secondary piston body 1 and described back piston body 2 joint diametric plane on offer groove 5 respectively, described secondary piston body 1 offers the first breach 6, and described first breach 6 is offered along the bottom of described groove 5 to the central direction of described secondary piston body 1, piston body 2 offers the second breach 7 in the rear, described second breach 7 is offered along the bottom of described groove 5 to the central direction of described secondary piston body 1, described first breach 6 is corresponding with described second breach 7 position, in the present embodiment, when described secondary piston body 1 with described back piston body 2 are connected, described first breach 6 is encircled into rectangle groove with described second breach 7, at described groove 5 built with upper and lower two magnetosphere linings 8, described magnetosphere lining 8 tundish is covered with magnetosphere 9, U-shaped ring 10 is fixed with in the periphery of described magnetosphere lining 8, described U-shaped ring 10 is positioned at described groove 5.
In assembly process, piston rod 4 is overlapped through described guide pin bushing 3, worm structure is provided with at guide pin bushing 3 internal layer of described secondary piston body 1, when the internal diameter of described guide pin bushing 3 is consistent with the external diameter of described piston rod 4, described guide pin bushing 3 can be connected with described piston rod 4 by screw-fashion, thus described secondary piston body 1 is connected with described piston rod 4, now due to the support of described secondary piston body 1, described back piston body 2 is enclosed within described piston rod 4, magnetosphere lining 8 and magnetosphere 9 are loaded in rectangle groove, can be fixed by U-shaped ring 10.
In order to be fixed described back piston body 2, guide pin bushing 3 top of piston body 2 offers shoulder hole in the rear, by the length of screw-fashion adjustment piston rod 4, the head of piston rod 4 can be made to proceed in the guide pin bushing 3 of described back piston body 2, when the head of described piston rod 4 enters in described shoulder hole, utilize nut 11 head of described piston rod 4 can be locked, thus described secondary piston body 1 is integrated with described back piston body 2 compact siro spinning technology.
In actual moving process; due to the regular friction of piston and cylinder body, magnetosphere 9 can be caused impaired, affect the working life of cylinder; in the present embodiment; by offering groove 5 and rectangle groove on described secondary piston body 1 and described back piston body 2, by magnetosphere lining 8, described magnetosphere is protected, the life-span of energy available protecting magnetosphere 9; described magnetosphere lining 8 is utilized to reduce friction factor; increase work efficiency, utilize U-shaped ring 10 to be fixed simultaneously, make overall structure safety and firmness.
In addition, what is more important, the present embodiment fixes U-shaped ring 10 without the need to the slotted eye offering other on secondary piston body 1 and back piston body 2, not only significantly reduces the difficulty of processing, and has saved material.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
