Abstract
The utility model relates to an electric automatic limit detection device which is a limit device of a hydraulic cylinder. The limit device comprises an inner sleeve, an outer sleeve, a limit baffle plate and a limit switch, wherein the inner sleeve is positioned in the outer sleeve to form a telescopic rod structure, the left end head of the inner sleeve is fixed on the fixed end of the hydraulic cylinder, the right end head of the inner sleeve moves in the outer sleeve, one end of the outer sleeve, which is far away from the left end of the inner sleeve, is fixed on the moving end of the hydraulic cylinder, the limit baffle plate is fixed on the outer sleeve, and the limit switch is linked with a switch of the hydraulic cylinder and is positioned on the moving direction of the limit baffle plate. The limit device has a simple structure and is convenient for use; and except that the limit device is aged and damaged, because steel pipes with two diameters are mutually embedded, the shaking of the fiber baffle plate is avoided completely, and the damage of the baffle plate to the limit device is reduced.
Description
Technical field
The utility model relates to a kind of electric automatization limit detection device, specifically a kind of oil hydraulic cylinder limit stoper.
Background technique
The smelting industry production environment is abominable, and when using oil hydraulic cylinder, the spacing of oil hydraulic cylinder can not be stablized and detect accurately, thereby can affect normally carrying out of production.In prior art, the general spacing buting iron that is welded on oil hydraulic cylinder that relies on is completed the spacing of oil hydraulic cylinder, there is jitter phenomenon in running due to oil hydraulic cylinder, thereby the spacing buting iron that causes being welded on oil hydraulic cylinder can not action message, the preparation that finally can't realize oil hydraulic cylinder is spacing, usually need manual operation, reduce manufacturing efficiency, increase labour cost.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of oil hydraulic cylinder limit stoper, can automatically carry out spacingly to oil hydraulic cylinder, greatly improved the stability of equipment, guarantee under abominable production environment spacing accurately.
The technological scheme that the utility model solves above technical problem is:
A kind of oil hydraulic cylinder limit stoper, comprise inner sleeve, outer sleeve, postive stop baffle and limit switch, inner sleeve is positioned at outer sleeve and forms Telescopic rod structure, the left end head of inner sleeve is fixed on the fixed end of oil hydraulic cylinder, the right-hand member head of inner sleeve moves in outer sleeve, and outer sleeve is fixed on the mobile terminal of oil hydraulic cylinder away from that end of inner sleeve left end, and postive stop baffle is fixed on outer sleeve, the switch gearing of limit switch and oil hydraulic cylinder, and be positioned on the movement direction of postive stop baffle.
The technological scheme that the utility model further limits is:
Aforesaid oil hydraulic cylinder limit stoper, inner sleeve are connected with outer sleeve and are connected with oil hydraulic cylinder by angle steel support.
Aforesaid oil hydraulic cylinder limit stoper, limit switch is fixed on limiting bracket.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, except spacing aged deterioration, because the steel pipe of two kinds of diameters is mutually nested, stop the shake of fiber baffle plate fully, thereby reduced baffle plate to spacing damage, and solved spacing loosening input a large amount of manpowers, greatly improved the stability of equipment, guaranteed spacing accurate and stable under abominable production environment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
The present embodiment is a kind of oil hydraulic cylinder limit stoper, structure as shown in Figure 1, comprise inner sleeve 1, outer sleeve 2, postive stop baffle 3 and limit switch 6, inner sleeve 1 is positioned at outer sleeve 2 formation Telescopic rod structures, the left end head of inner sleeve 1 is fixed on the fixed end of oil hydraulic cylinder, the right-hand member head of inner sleeve 1 is in the interior movement of outer sleeve 1, outer sleeve 1 is fixed on the mobile terminal of oil hydraulic cylinder away from that end of inner sleeve left end, postive stop baffle 3 is fixed on outer sleeve 2, the switch gearing of limit switch 6 and oil hydraulic cylinder, and be positioned on the movement direction of postive stop baffle 3.Inner sleeve 1 is connected with outer sleeve and is all passed through angle steel support 4 and be connected with oil hydraulic cylinder.Limit switch 6 is fixed on limiting bracket 5.Move along with moving of oil hydraulic cylinder drives outer sleeve, postive stop baffle is fixed on outer sleeve, and along with external sleeve moves together, when baffle plate is encountered limit switch, by control, oil hydraulic cylinder is stopped mobile.
When the utility model is specifically made, first portion by the angle steel of long 230mm as base, with the long 90mm diameter steel-pipe welding that is 40mm on this base; The angle steel of the long 15mm of second portion is as base, and the long 90mm diameter steel-pipe welding that is 35mm on this base, is poured into first portion with second portion, forms Telescopic rod structure, can complete doing antirust processing.The material of base and pipe and length can and use the actual conditions at position to adjust according to site environment.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
