Description
Technical field
But the utility model relates to a kind of beat displacement sensing apparatus, but especially relates to a kind of oil cylinder beat displacement sensing apparatus.
Background technique
At present, domestic and international large and medium-sized oil cylinder displacement transducer all is to utilize the restoring force of spring to keep sensor and oil cylinder synchronous operation, to reach the purpose that detects displacement.But the oil cylinder piston diameter is big (being generally about φ 1500mm), and stroke very little (being generally about 80mm), add a certain amount of gap is arranged between piston and the cylinder body, therefore piston the beat phenomenon can occur in movement process, because common sensor is to utilize spring to connect piston, sensor is also followed the piston beat in movement process, if swing angle is big, can make the sensor sliding axle be subjected to lateral force, accelerate to wear and tear between the axle sleeve, and occur stuck phenomenon easily, and even damage sensor.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of when the oil cylinder piston beat non-damageable oil cylinder displacement sensing apparatus.
The purpose of this utility model can be achieved through the following technical solutions:
But a kind of beat displacement sensing apparatus, it is characterized in that: this device comprises sensor, sensor outer housing assembly, mounting bracket and Hooks coupling universal coupling, described sensor is located at the middle part of this device, described sensor outer housing assembly is located at the outside of sensor, described mounting bracket is located at the middle part of this device, and described Hooks coupling universal coupling is located at an end of this device.
Described sensor is made up of magnetic railings ruler and magnetic head.
Described sensor outer housing assembly comprises shell, protecgulum, bonnet, connecting head, chuck is installed and is sat, chuck, sliding axle, cross the line cover, hood, described shell two ends are provided with protecgulum and bonnet, described connecting head is located at the top of shell, one end of this connecting head connects Hooks coupling universal coupling, the other end connects the chuck fitting seat, described chuck is located on the chuck fitting seat, this chuck connects magnetic railings ruler, described sliding axle is located at the middle part of this device, the slide rule head of this sliding axle internal fixation magnetic railings ruler, described line excessively is set in the inboard of sliding axle, and described hood is located on the bonnet.
In the described mounting bracket lining is set.
The bottom of described magnetic head is provided with packing ring.
Compared with prior art, the utlity model has following advantage:
(1) applied widely: as to be suitable for medium-and-large-sized oil cylinder, the oil cylinder of some band deflection angle;
(2) long service life: sensor can rotate flexibly by Hooks coupling universal coupling and mounting bracket, 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. 2 is a structural representation of the present utility model.
Among the figure, 1 is that connecting head, 2 is that chuck fitting seat, 3 is that chuck, 4 is that magnetic railings ruler, 5 is that magnetic head, 6 is that packing ring, 7 is that lining, 8 is that shell, 9 is that sliding axle, 10 was that line cover, 11 is that locking nut, 12 is that Hooks coupling universal coupling, 13 is that protecgulum, 14 is that mounting bracket, 15 is that bonnet, 16 is a hood.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
But a kind of beat displacement sensing apparatus, its structure is shown in Fig. 1-2: this device comprises sensor, sensor outer housing assembly, Hooks coupling universal coupling 12 and mounting bracket 14, sensor is located at the middle part of this device, the sensor outer housing assembly is located at the outside of sensor, Hooks coupling universal coupling 12 is located at an end of this device, mounting bracket 14 is located at the middle part of this device, and inside is provided with lining 7.Wherein, sensor is made up of magnetic railings ruler 4 and magnetic head 5, and the bottom of magnetic head 5 is provided with packing ring 6.The sensor outer housing assembly comprises connecting head 1, chuck installation seat 2, chuck 3, shell 8, sliding axle 9, crosses line cover 10, protecgulum 13, bonnet 15, hood 16.The two ends of shell 8 are provided with protecgulum 13 and bonnet 15, connecting head 1 is located at the top of sliding axle 9, one end of this connecting head 1 connects Hooks coupling universal coupling 12, and the other end connects chuck fitting seat 2, and chuck 3 is located on the chuck fitting seat 2, this chuck 3 connects magnetic railings ruler 4, sliding axle 9 is located at the middle part of this device, and the slide rule head of these sliding axle 9 internal fixation magnetic railings rulers 5 is crossed the inboard that line cover 10 is located at sliding axle 9, cross line cover 10 and be connected on the bonnet 15 through locking nut 11, hood 16 is connected on the bonnet 15 through screw.
During use, universal shaft coupling device 12 is connected on the piston, when beat appears in piston, universal shaft coupling device 12 can be along with lateral force deflects, mounting bracket 14 also can rotate along with the piston beat, Hooks coupling universal coupling 12, connecting head 1, chuck fitting seat 2, chuck 3, sliding axle 9 are formed a slide mass, drive magnetic railings ruler 4 motions, lining 7 is enclosed within on the protruding axle on the shell 8, mounting bracket 14 is clamped lining 7, mounting bracket 14 is connected with oil cylinder, and magnetic railings ruler 4 is done the generation reading that moves back and forth for 5 li at magnetic head, control oil cylinder roll gap.Because Hooks coupling universal coupling 12 can rotate in several angle, mounting bracket 14 also can deflection in several angle, so sensor has well solved in reading process, even beat appears in oil cylinder piston in movement process, also make sensing device not be subjected to the influence of lateral force, thereby the wearing and tearing between the sensing device axle sleeve have been avoided, stuck phenomenon, increased the working life of sensing device, protecgulum 13 and shell 8, mounting bracket 14 and shell 8, bonnet 15 adopts screw to be connected with hood 16, crossing line cover 10 adopts locking nut to be connected with bonnet 15, when sensing device need be changed easily damaged parts, can be by backing out screw, locking nut is pulled down corresponding casing assembly and is changed.
