Abstract
The utility model relates to a connecting rod type oil cylinder displacement sensor. The connecting rod type oil cylinder displacement sensor comprises a sensor, a shell component, a connecting rod and a mounting bracket, wherein the sensor is arranged in the middle of the device; the shell component is arranged outside the sensor; the mounting bracket is arranged at the lower part of the device; and the connecting rod is arranged at one end of the device. Compared with the prior art, the connecting rod type oil cylinder displacement sensor has the advantages that the condition that a shaft sleeve of the sensing device is worn when the sensing device swings slightly in an oil cylinder which generates gap during motion of a piston and a cylinder body is avoided; the sensing device is prevented from being jammed and damaged; the service life of the sensing device is greatly prolonged; and the connecting rod type oil cylinder displacement sensor is convenient to maintain and quick-wear parts are convenient to replace.
Description
Technical field
The utility model relates to a kind of oil cylinder displacement sensing apparatus, especially relates to a kind of linkage type oil cylinder displacement sensing apparatus.
Background technique
At present, steel mill's oil cylinder all is to adopt the mode of rigid connection keeping sensor and oil cylinder synchronous operation with the finish rolling sensor both at home and abroad, to reach the purpose that detects displacement.Because the oil cylinder piston diameter is larger, stroke little (100～200), a certain amount of gap is arranged between piston and the cylinder body, add upper cylinder pressurization and oil and lift in the process of cylinder, two ends, the left and right sides are not well-balanced, therefore in movement process beat can appear, the sensor sliding axle can be subject to lateral force, because sensor adopts the mode of rigid connection, so can accelerate the wearing and tearing between axle and the axle sleeve, and stuck phenomenon occurs, to such an extent as to damage sensor.
The model utility content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of in the cylinder movement process non-damageable linkage type oil cylinder displacement sensing apparatus.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of linkage type oil cylinder displacement sensing apparatus comprises:
Sensor;
Casing assembly: be arranged on outside the sensor;
Mounting bracket: the lower end that is connected to casing assembly;
Connecting rod: the upper end that is movably connected in casing assembly.
Described sensor is comprised of magnetic railings ruler and magnetic head.
Described casing assembly comprises sliding axle, end cap, sleeve assembly, copper sheathing, axle sleeve, chuck, nylon is crossed the line cover, nylon guide sleeve and mistake line end lid, described end cap is located at the outboard end of sliding axle, described sleeve assembly consists of the shell of casing assembly, described copper sheathing has two groups, be located at the inboard of sleeve assembly, described axle sleeve is located between two groups of copper sheathings, described chuck is located at the top of sleeve assembly, be connected with magnetic railings ruler, described nylon is crossed the line cover and is connected magnetic railings ruler and magnetic head, described nylon guide is to the below that is set in magnetic head, and the described line end of crossing covers the end that is located at nylon guide sleeve downside.
Described magnetic head, nylon are crossed the line cover and cross the line end lid fixing by the screw rod link.
The top of described magnetic head arranges the nylon guide sleeve, and the bottom arranges nylon and crosses the line cover.
Described connecting rod, sleeve assembly, copper sheathing, axle sleeve and chuck form the slide mass that drives the magnetic railings ruler motion.
Compared with prior art, the utlity model has following advantage:
(1) applied widely: as to be suitable for various finish rolling production lines;
(2) long service life: sensor can solve the beat problem by connecting rod, makes sensor can follow the piston beat, has avoided sensor stuck, damages;
(3) easy to maintenance: mounting or dismounting are easy when changing easily damaged parts.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic representation of the present utility model.
Among the figure, 1 to cross line cover, 13 for magnetic head, 12 for nylon for nylon guide sleeve, 11 for magnetic railings ruler, 10 for chuck, 9 for outlet-pipe joint, 8 for mounting bracket, 7 for sliding axle, 6 for axle sleeve, 5 for copper sheathing, 4 for sleeve assembly, 3 for connecting rod, 2 be that line end lid, 14 is end cap.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of linkage type oil cylinder displacement sensing apparatus, its structure is shown in Fig. 1-2: this device comprises sensor, casing assembly, connecting rod 1 and mounting bracket 6, sensor is located at the middle part of this device, casing assembly is located at the outside of sensor, connecting rod 1 is located at an end of this device, and mounting bracket 6 is located at the afterbody of this device.Wherein, sensor is comprised of magnetic railings ruler 9 and magnetic head 11, and the bottom of magnetic head 11 arranges nylon and crosses line cover 12.Casing assembly comprises sliding axle 5, end cap 14, sleeve assembly 2, chuck 8, line end lid 13, copper sheathing 3, nylon are crossed line cover 12, nylon guide sleeve 10, axle sleeve 4 excessively.The inside of sleeve assembly arranges copper sheathing 3, axle sleeve 4 is set between the copper sheathing 3, the upper interior portion of sleeve assembly 2 arranges chuck 8, chuck 8 link magnetic railings rulers 9, connecting rod 1 is fixed on the top of sleeve assembly 2 through screw, sliding axle 5 is arranged on the middle part of this device, magnetic head 11 is arranged on the middle part of sliding axle, one end of magnetic head 11 arranges nylon guide sleeve 10, nylon guide sleeve 10 is fixed by circlip for hole, one end of magnetic head 11 arranges nylon and crosses line cover 12, nylon is crossed a section of line cover 12 line end lid 13, magnetic head 11 was set, nylon is crossed line cover 12, it is fixing by the screw rod link to cross line end lid 13, crosses line end lid 13 and is connected and fixed by screw and sliding axle 5, end cap 14 is connected on the sliding axle 5 through screw, is provided with outlet-pipe joint 7 at end cap 14.
During use, connecting rod 1 is connected with the piston pressing plate, connecting rod 1, sleeve assembly 2, copper sheathing 3, axle sleeve 4, chuck 8 form a slide mass, drive magnetic railings ruler 9 motions, mounting bracket 6 is sliding axle 5 fixedly, mounting bracket 6 is connected with oil cylinder, and magnetic railings ruler 9 is done the generation reading that moves back and forth 11 li of magnetic heads, control oil cylinder roll gap.Because the elongate rod of connecting rod 1 part can crookedly be offset the beat that oil cylinder piston occurs, make sensor that beat not occur and keep vertical motion, so sensor has well solved in reading process, even beat appears in oil cylinder piston in movement process, so that sensing device is not subjected to the impact of lateral force yet, thereby avoided wearing and tearing, stuck phenomenon between the sensing device axle sleeve, increased the working life of sensing device.When sensing device need to be changed easily damaged parts, can pull down corresponding casing assembly and change by backing out screw.
