Abstract
The invention provides a limiting device of an oil cylinder. The limiting device of the oil cylinder comprises fixing plates, two proximity switches, an induction head, an outer sleeve pipe, an inner rod and a connecting plate which are installed on the oil cylinder. The two proximity switches are both installed on the fixing plates, the outer sleeve pipe and the oil cylinder are arranged on the fixing plates in an axially parallel mode, a through groove is formed in the side face of the outer sleeve pipe in the axial direction, the induction head is installed on the inner rod, the inner rod is inserted into the outer sleeve pipe and in sliding connection with the outer sleeve pipe, the induction head is in sliding connection with the through groove and is located between the two proximity switches, and the two ends of the connecting plate are connected with the inner rod and a piston rod of the oil cylinder respectively. The limiting device of the oil cylinder is simple in structure, convenient to install and operate and capable of effectively limiting the oil cylinder; due to the fact that the limiting device is installed on the outer side of the oil cylinder, the limiting device is convenient to install, adjust and maintain.
Description
Technical field
The present invention relates to the spacing technical field of oil cylinder.
Background technique
The built-in position-limit mechanism of the many employings of limit stoper of existing oil cylinder, owing to being positioned at oil cylinder, for device maintenance, replacing etc., very inconvenient, and due to the difference according to actual production, need to arrange different oil cylinder Upper-lower Limit positions, because limit stoper is positioned at oil cylinder, the Upper-lower Limit position of oil cylinder can not be adjusted timely, operation inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is: overcome built-in position-limit mechanism maintenance in prior art, change inconvenient deficiency, provide a kind of limit stoper of oil cylinder.
The technical solution adopted for the present invention to solve the technical problems is: a kind of limit stoper of oil cylinder, comprises the fixed plate be arranged on oil cylinder, proximity switch, inductive head, outer sleeve, interior bar, connecting plate;
Described proximity switch quantity is two, be installed on fixed plate, described outer sleeve and oil cylinder parallel to an axis are arranged on fixed plate, and groove outer sleeve side offered along its axis, described inductive head is arranged on described interior bar, and described interior bar is plugged in outer sleeve, and be slidably connected with outer sleeve, described inductive head and described groove are slidably connected, and inductive head is between two proximity switches, and described connecting plate two ends are connected with interior bar and cylinder piston rod respectively.According to actual conditions, in fact two proximity switches are arranged on oil cylinder respectively, lower limit position place, pneumatic oil cylinder, during oil cylinder drive piston rod to-and-fro motion, piston rod drives connecting plate motion, in connecting plate drives, bar slides in outer sleeve, thus drive inductive head to slide in groove, when inductive head is near proximity switch, proximity switch senses that inductive head is (during for ensureing that inductive effects inductive head reaches with proximity switch proximal most position, distance between inductive head and proximity switch should be less than 10mm), namely illustrate and reach or lower position place, oil cylinder stops, random direction towards the opposite motion, circulation like this.
Slide in groove for ease of inductive head, as preferably, described groove width is slightly larger than inductive head diameter, and inductive head can not produce skew simultaneously.
Further, for ease of according to different oil cylinder in fact, the difference of lower limit position or regulate the stroke of oil cylinder to adjust the position of proximity switch as required, described device also comprises switch bearing, and described proximity switch is arranged on fixed plate by switch bearing.
Further, described proximity switch is connected with external control circuit, when proximity switch senses inductive head, by Signal transmissions to control circuit, is controlled the motion of oil cylinder by external control circuit.
The invention has the beneficial effects as follows, simply, installation, operation are all very convenient, effectively can play position-limiting action to oil cylinder, and be arranged on the outside of oil cylinder for structure of the present invention, and installation, adjustment, attending device are conveniently.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is oil cylinder limit device structure schematic diagram of the present invention;
Fig. 2 is A place schematic enlarged-scale view in Fig. 1;
In figure: 1. oil cylinder, 11. piston rods, 2. fixed plate, 21. switch bearing, 3. proximity switch, 4. contact head, 5. outer sleeves, 51. grooves, bar 6., 7. connecting plate.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As illustrated in fig. 1 and 2, a kind of limit stoper of oil cylinder 1, comprises the fixed plate 2 be arranged on oil cylinder 1, proximity switch 3, inductive head 4, outer sleeve 5, interior bar 6, connecting plate 7;
Described proximity switch 3 quantity is two, be installed on fixed plate 2, described outer sleeve 5 is arranged on fixed plate 2 with oil cylinder 1 parallel to an axis, and the groove 51 outer sleeve 5 side offered along its axis, described inductive head 4 is arranged on described interior bar 6, described interior bar 6 is plugged in outer sleeve 5, and be slidably connected with outer sleeve 5, described inductive head 4 is slidably connected with described groove 51, described groove 51 width is slightly larger than inductive head 4 diameter, and inductive head 4 is between two proximity switches 3, described connecting plate 7 two ends are connected with interior bar 6 and oil cylinder 1 piston rod 11 respectively.Described device also comprises switch bearing 21, and described proximity switch 3 is arranged on fixed plate 2 by switch bearing 21.Described proximity switch 3 is connected with external control circuit, when proximity switch 3 senses inductive head 4, by Signal transmissions to control circuit, is controlled the motion of oil cylinder 1 by external control circuit.
According to actual conditions, two proximity switches 3 are arranged on respectively oil cylinder 1 in fact, lower limit position place, pneumatic oil cylinder 1, when oil cylinder 1 drives piston rod 11 to-and-fro motion, piston rod 11 drives connecting plate 7 to move, connecting plate 7 drives interior bar 6 to slide in outer sleeve 5, thus drive inductive head 4 to slide in groove 51, when inductive head 4 is near proximity switch 3, proximity switch 3 senses inductive head 4, and namely illustrate and reach or lower position place, oil cylinder 1 stops, direction towards the opposite motion, so circulates immediately.
