Abstract
The utility model relates to a piston which is used for opening and closing a cylinder. The utility model comprises a piston body, and a magnetic loop which is arranged on the piston body. The utility model is characterized in that the piston body is a whole element, and the magnetic loop at least comprises two separated elements which are inlaid in corresponding annular grooves which are arranged on an outer wall of the piston body to be spliced into a whole annular shape. The utility model causes the traditional separated piston and the traditional whole magnetic loop to be changed into the whole piston and the separated magnetic loop, and therefore, only a pair of dies of the blank of the piston is required, the manufacturing procedures are reduced correspondingly, and the manufacturing cost is reduced. Besides, because a magnetic loop installing groove is only required to be processed on piston, the concentricity after the piston and a piston rod is easy to guarantee, and the quality of the product can be guaranteed.
Description
Technical field
The utility model relates to a kind of piston element of cylinder, particularly a kind of piston of switch cylinder.
Background technique
So-called switch cylinder claims carrying magnetic switch cylinder again, is meant that cylinder piston is provided with permanent magnet ring, and utilizes the position limit switch that is directly installed on the cylinder barrel to detect a kind of cylinder of piston position.In the piston of existing switch cylinder, magnet ring 2 ' be a whole annulus, piston body 1 ' then involute by two separated portions 1a ', 1b ', magnet ring 2 ' promptly be sandwiched in therebetween, as shown in Figure 3, Figure 4, therefore, during fabrication, the mould of piston blank must have two pairs, and in that to add the man-hour operation also more, thereby manufacture cost is increased, on the other hand, when assembling piston and piston rod, also be difficult to guarantee its concentricity, be difficult to guarantee the quality of product.
Summary of the invention
Technical problem to be solved in the utility model is the piston that a kind of low cost of manufacture, switch cylinder easy to assembly are provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the piston of switch cylinder comprises piston body and the magnet ring that is provided with on it, it is characterized in that described piston body is a single piece, described magnet ring then comprises two split parts at least, be embedded on the piston body outer wall in the corresponding annular groove, and be spliced into one integral ring-shaped.
Compared with prior art, the utility model changes traditional split piston, whole magnet ring is solid piston, split magnet ring, therefore the mould of piston blank only needs a pair, manufacturing procedure also reduces relatively, thereby reduce manufacture cost greatly, and owing to only need one magnet ring mounting groove of processing on piston, the concentricity after piston and the piston rod assembling guarantees easily that also therefore the quality of product is also guaranteed.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the piston of switch cylinder comprises piston body 1 and the magnet ring 2 that is provided with on it, and described piston body 1 is a single piece, and 2 of described magnet rings include two semi-ring 2a, 2b, be embedded on piston body 1 outer wall in the corresponding annular groove, and be spliced into one integral ring-shaped.3 is supporting ring among the figure, and 4 is seal ring, and 5 is cylinder barrel.
Claims (2)
1, a kind of piston of switch cylinder, comprise piston body and the magnet ring that is provided with on it, it is characterized in that described piston body is a single piece, described magnet ring then comprises two split parts at least, be embedded on the piston body outer wall in the corresponding annular groove, and be spliced into one integral ring-shaped.
2, the piston of switch cylinder according to claim 1 is characterized in that described magnet ring is spliced by two semi-rings.
