Abstract
The utility model relates to an oil cylinder with position output signals, in particular to a multi-point output oil cylinder with positions of detection points adjustable. The multi-point output oil cylinder with positions of detection points adjustable comprises a cylinder body, a piston and a piston rod. A deep hole and a stainless steel protecting tube arranged in the deep hole are arranged in the piston rod. A multi-point magnetic induction switch detecting mechanism is arranged in the stainless steel protecting tube along the axial direction of the piston rod. One end of the piston close to the bottom of the cylinder body is provided with a magnetic ring. As the deep hole is arranged in the piston rod of the oil cylinder, the bottom of the cylinder is provided with the sealed stainless steel oil tube, and the piston of the oil cylinder is provided with the strong magnetic ring, when the piston moves and passes through a multi-point magnetic switch in a detection tube, the switch closes to send out signals, so the multi-point output oil cylinder with positions of detection points adjustable can freely adjust positions of detection points, outputs in a multi-point mode, and ensures normal operation of the oil cylinder due to the fact that adjustment of the signal positions and maintenance are not related to the sealing of the oil cylinder after the stainless steel protecting tube is sealed.
Description
Technical field
The utility model relates to the oil cylinder of being with position output signal, particularly a kind of band multiple spot position adjustable output cylinder.
Background technique
In the oil cylinder of band position output signal, a kind of is the oil cylinder of band continuous position signal, and this oil cylinder adopts displacement transducer to realize; But price is higher; Especially imported product, synchronous signal receiving and processing equipment price is also higher, and is improper for the user who only needs the discrete point signal.The simple relatively method of another kind is exactly to install near switch or magnetic switch in oil cylinder bottom and cylinder cap position, but this method can only be exported the signal of two fixing extreme positions, can not satisfy the intermediate point position Detection.
The model utility content
The technical problem that the utility model will solve is: in order to overcome in the existing technology, the oil cylinder cost height of band position output signal perhaps can only be exported the deficiency of fixed position signal, and the utility model provides a kind of band multiple spot position adjustable output cylinder.
The inventor considers, exports the signal of intermediate point position if desired, can not adopt certainly penetrate cylinder body near switch; Can only use magnetic switch; Because the restriction of the working principle of magnetic switch, cylinder body must be a stainless steel, and is obviously just improper on cost for bigger slightly oil cylinder.
The utility model solves the technological scheme that its technical problem adopted: a kind of band multiple spot position adjustable output cylinder; Comprise cylinder body, piston and piston rod; Be provided with deep hole and the stainless steel protection pipe that is arranged in the deep hole in the described piston rod; Be provided with in the described stainless steel protection pipe along piston rod to multiple spot magnetic switch feeler mechanism, described piston is equipped with magnet ring near an end of cylinder base.
Described multiple spot magnetic switch feeler mechanism comprises a plurality of magnetic switchs that are arranged side by side and the detecting tube that is used for fixing magnetic switch, and described magnetic switch all is arranged in the detecting tube.
In order not influence the proper functioning of oil cylinder, described stainless steel protection pipe is the sleeve pipe of sealing.As preferably, described stainless steel protection pipe is the stainless steel oil pipe of sealing.
The degree of depth of described deep hole in piston rod is the stroke and the piston axial length sum of oil cylinder.
The beneficial effect of the utility model is; The utility model band multiple spot position adjustable output cylinder; In oil cylinder piston bar deep hole processing, cylinder bottom is installed the stainless steel oil pipe of sealing, and powerful magnet ring is installed on the oil cylinder piston; When the multiple spot magnetic switch in the piston motion process detecting tube, switch on sends signal; Can freely adjust the Check point position, multiple spot output, after the stainless steel protection sleeve pipe was carried out sealing, the adjustment of signal location and maintenance were all irrelevant with cylinder seal, had guaranteed the proper functioning of oil cylinder.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the optimum embodiment's of the utility model band multiple spot position adjustable output cylinder a structural representation.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure 1, cylinder base, 2, deep hole, 3, the stainless steel protection pipe, 4, multiple spot magnetic switch feeler mechanism, 5, piston, 6, cylinder body, 7, piston rod, 8, cylinder cap, 9, magnet ring.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Like Fig. 1, shown in Figure 2, the optimum embodiment's of the utility model band multiple spot position adjustable output cylinder structural representation.Comprise cylinder body 6, piston 5 and piston rod 7; Be provided with deep hole 2 and the stainless steel protection pipe 3 that is arranged in the deep hole 2 in the piston rod 7; Be provided with in the stainless steel protection pipe 3 along the axial multiple spot magnetic switch feeler mechanism 4 of piston rod 7; Stainless steel protection pipe 3 is the stainless steel oil pipe of sealing; Multiple spot magnetic switch feeler mechanism 4 is enclosed in the pipe, and multiple spot magnetic switch feeler mechanism 4 is made up of a plurality of magnetic switchs that are arranged side by side and the detecting tube that is used for fixing magnetic switch, and magnetic switch all is arranged in the detecting tube; Piston 5 is equipped with magnet ring 9 near an end of cylinder base 1, and when the multiple spot magnetic switch in the piston 5 motion process multiple spot magnetic switch feeler mechanisies 4, corresponding magnetic switch closure is sent signal.
The degree of depth of deep hole 2 in piston rod 7 is the stroke and the piston axial length sum of oil cylinder.With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
