Abstract

The utility model relates to the protective device of a hydraulic cylinder position sensor, which comprises a position sensor protective cover and connecting bolts, wherein the position sensor protective cover is sheathed on the external side of a hydraulic cylinder lever and the position senor and is fixed on a hydraulic cylinder through the connecting bolts. The utility model has the advantages that the structure is simple, the installation is convenient, the sensor is effectively protected against scratches and damages, the accuracy of results detected by the sensor is ensured, the rejection rate is reduced and the production benefit is improved.

Description

The protective gear of Position of Hydraulic Cylinder sensor
Technical field
The utility model has related to a kind of protective gear, has particularly related to a kind of protective gear of Position of Hydraulic Cylinder sensor.
Background technique
Along with China's rapid development of economy, heighten to the demand of flat cold-rolled sheet in market.Domestic each iron and steel enterprise satisfies the demand of market to cold-reduced sheet, newly-built successively a collection of rolling mill production line or original production line undergone technological transformation enhance production capacities and promote product performance.No matter newly-built or technical innovation, milling train generally all adopts the AGC Hydrauservo System that steel plate is carried out automatic continuous closed-loop control now.The position probing of oil hydraulic cylinder cylinder bar is an important ring in this course.Rodmeter is more elongated and require the position in magnet ring accurate, can not deflection or scratching magnet ring, otherwise will influence the magnet ring detection accuracy, the production of steel plate is impacted.In actual production process, often occur normally detecting thereby influenced magnet ring because outside scratching causes the rodmeter distortion, cause the waste product influence to produce.Because the sensor mounting point is narrow and small, not easy care, and the replacing time is long, has influenced manufacturing efficiency greatly.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of protective gear of Position of Hydraulic Cylinder sensor of simple in structure, easy installation and removal is provided.This device has effectively avoided position transducer by the foreign object scratching, has guaranteed the accurate of position transducer testing result.
In order to address the above problem, the utility model by the following technical solutions:
A kind of protective gear of Position of Hydraulic Cylinder sensor, this device comprises position transducer safety cover and connecting bolt, the position transducer safety cover is enclosed within the outside of oil hydraulic cylinder lever and position transducer and is fixed on the oil hydraulic cylinder by connecting bolt.
Described position transducer safety cover comprises that protection goes up cover and protection cover down, and cover and protection are connected and fixed by connecting bolt between the cover down protection in, cover under the protection to be fixed on the oil hydraulic cylinder by connecting bolt.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, be enclosed within the position transducer outside, effectively avoided position transducer by the phenomenon of foreign object scratching, prevent that fluid from entering, guarantee sensor result's accuracy rate, effectively reduced reject rate, thereby improved enterprise's productivity effect.
Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
A kind of protective gear of Position of Hydraulic Cylinder sensor; as shown in Figure 1; this device comprises position transducer safety cover and connecting bolt 3; the position transducer safety cover is enclosed within the outside of oil hydraulic cylinder lever 6 and position transducer 1; the position transducer safety cover comprises protecting goes up cover 5 under cover 2 and the protection; cover 2 and protection are connected and fixed by connecting bolt 3 between the cover 5 down in the protection, and protection cover 5 down is fixed on the oil hydraulic cylinder 4 base glands by connecting bolt 3.
After this protective gear is installed, stock rod and magnet ring are protected simultaneously, do not influence the normal detection of magnet ring and other functions of system, prevent that fluid from entering, effectively improved rolling accuracy.
