Abstract
The invention discloses a displacement distance sensor for the clutch brake of a press machine. The solid casing of the displacement distance sensor is composed of a rear end cover, an outer sleeve and a front end cover which are made of stainless steel and is used for preventing magnetic diffusion of internal magnetic steel; the magnetic steel is installed in a cavity at the rear end of a measuring rod; the measuring rod is connected with a copper inner sleeve through threads, and the copper inner sleeve is used for preventing strong peripheral electromagnetic interference; the front end of a spring is installed in an annular space formed by the measuring rod and the copper inner sleeve, and the rear end of the spring abuts against the rear end cover so that the measuring rod has a self-resetting function; since the front end of the measuring rod is equipped with steel beads, on one hand, movement blocking of the measuring rod can be effectively prevented, and bending deformity of the measuring rod cannot be caused by the radial motion of brake shoes on the other hand; a positioning pin is matched with a groove on the outer surface of the copper inner sleeve, thereby preventing free rotation of the measuring rod; and a Hall element and a circuit board of the Hall element are also installed on the rear end cover, and leading wires of the circuit board are led out by an aviation plug.
Description
Technical field
The present invention relates to a kind of pressing machine displacement transducer, particularly a kind of pressing machine clutch-brake shift length sensor belongs to pressing machine control technology field.
Background technology
The shift length of pressing machine clutch-brake, reacted the performance of pressing machine clutch-brake, and the quality of braking ability, but pressing machine uses for a long time or occurs when unusual, the shift length of clutch-brake will change, thereby might cause device security and other security incident, at present, also do not have special displacement transducer for the pressing machine clutch-brake, this is for guaranteeing that pressing machine is normal, there is certain potential safety hazard in safe handling.
Summary of the invention
The objective of the invention is to: a kind of measuring accuracy height is provided, and antijamming capability is strong, and volume is little, a kind of pressing machine clutch-brake displacement transducer that cost is low.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of pressing machine clutch-brake displacement transducer, it is to be made of cover, front end end cover, sounding rod, Hall element and circuit board thereof, spring, magnet steel and aviation plug in rear end cap, overcoat, the copper, wherein: be set in the overcoat in the copper, the sounding rod rear portion is located in the copper and also is threaded togather with it in the cover, overcoat is stretched out in the front portion of sounding rod, and front end end cover passes the sounding rod head threads and fixedly puts outside the stockaded village; Rear end cap is located at the overcoat rear end, and Hall element and circuit board river spring thereof are located at the rear end cap bottom, and its circuit board leads is drawn by the aviation plug that is located at the rear end cap bottom, and the spring other end is on sounding rod, and magnet steel is located in the groove of sounding rod afterbody; Cover is axially arranged with gathering sill with the overcoat surface of contact in the described copper, and outer the putting of corresponding gathering sill position is provided with the register pin that can slide along the gathering sill front and back; The head of described sounding rod is provided with and prevents that the stuck or measuring staff of its motion is diastrophic by steel ball sleeve be located at the rolling body that the steel ball in the steel ball sleeve is formed.
Principle of work of the present invention is: sounding rod is pressing closer clutch coupling under the effect of spring displacement component moves the inner chamber of sounding rod rear end together; In be provided with magnet steel, magnet steel is just along with sounding rod moves together, a Hall element is placed in the sensor bottom, when magnet steel moves along with sounding rod, the magnetic field intensity that acts in the Hall unit changes, magnetic field intensity changes and is proportional to the variation of displacement, has just obtained displacement by detecting this change of magnetic field strength.
Beneficial effect: the present invention has simple in structure, and is easy for installation, the measuring accuracy height, and antijamming capability is strong, and volume is little, and is sturdy and durable, and price is lower, can guarantee normal, the safe handling of pressing machine, overcomes the potential safety hazard of depositing.
Description of drawings
Fig. 1 is the structural drawing that the present invention measures the displacement transducer of brake clearance.
Shown in the figure: cover, 4 front end end covers, 5 sounding rods, 6 steel ball sleeves, 7 steel balls, 8 Hall elements, 9 springs, 10 magnet steel, 11 register pins, 12 aviation plugs in 1 rear end cap, 2 overcoats, 3 bronze medals.
Embodiment
The present invention is further illustrated below in conjunction with the embodiment in the accompanying drawing:
Rear end cap (1), overcoat (2) and front end end cover (4) adopt stainless steel material, constitute the firm shell of sensor, effectively prevent the magnetic diffusion of inner magnet steel (10) simultaneously; Magnet steel (10) is installed in the cavity of rear end of sounding rod (5); Cover (3) effectively prevents peripheral strong electromagnetic by being threaded togather with cover (3) in the copper in sounding rod (5) and the copper; The front end of spring (9) is installed in the annulus that cover (3) forms in sounding rod (5) and the copper, and the rear end heads on rear end cap (1), makes sounding rod (5) have from reset function; The front end of sounding rod (5) is installed steel ball (7), prevents effectively that on the one hand sounding rod (5) motion is stuck, and the radial motion of brake shoe can not cause sounding rod flexural deformation yet on the other hand; Cover (3) outer surface groove cooperates in register pin (11) and the copper, prevents that sounding rod (5) from freely rotating; Hall element and circuit board thereof (8) also are installed on the rear end cap (1), and circuit board leads is drawn by aviation plug (12).
Claims (1)
1. pressing machine clutch-brake displacement transducer, it is made up of cover, front end end cover, sounding rod, steel ball sleeve, steel ball, Hall element, spring, magnet steel, register pin, aviation plug in rear end cap, overcoat, the copper, it is characterized in that: be provided with magnet steel in the inner chamber of sounding rod rear end, Hall element is located at the rear end cap bottom.
