Technical field
The invention belongs to linear movement pick-up designing technique, relate to a kind of linear movement pick-up being convenient to adjust zero-bit.
Background technology
Current linear movement pick-up self is not with zero-bit adjusting mechanism, the method of its adjustment zero-bit is see Fig. 1, with mounting flange 3 on linear movement pick-up 1 housing, by screw 2, mounting flange 3 is fixed on the outside surface on carrier around linear movement pick-up mounting hole, the mover iron core of linear movement pick-up 1 has a locating cylinder 5, and locating cylinder 5 is positioned at the linear movement pick-up mounting hole on carrier.There is adjustment packing ring 4 between outside surface on mounting flange 3 and carrier around linear movement pick-up mounting hole, reached the object of adjustment zero-bit by the thickness changing adjustment packing ring 4.Its shortcoming is: the first, need repeatedly to dismantle linear movement pick-up during adjustment, time-consuming, inefficiency; The second, adjustable range is little and can only unidirectionally adjust.
Summary of the invention
The object of the invention is: propose a kind of linear movement pick-up being convenient to adjust zero-bit, to simplify the step of zero-bit adjustment, avoid repeatedly dismantling linear movement pick-up, improve the work efficiency of zero-bit adjustment; Meanwhile, there is two-way adjustment function, expand setting range.
Technical scheme of the present invention is: a kind of linear movement pick-up being convenient to adjustment zero-bit, comprise a linear movement pick-up 1, with mounting flange 3 on linear movement pick-up 1 housing, by screw 2, mounting flange 3 is fixed on the outside surface on carrier around linear movement pick-up mounting hole, the mover iron core of linear movement pick-up 1 has a locating cylinder 5, and locating cylinder 5 is positioned at the linear movement pick-up mounting hole on carrier, it is characterized in that: the adjustment assembly mounting hole having through track displacement transducer 1 left side and right side on the housing of linear movement pick-up 1, the axis of adjustment assembly mounting hole and the axis being parallel of linear movement pick-up 1, adjustment assembly mounting hole is the stepped hole that left sector hole footpath is greater than right sector hole footpath, in above-mentioned left sector hole, have internal thread, there is one by adjustment nail 6, the zero-bit adjustment assembly that set nut 7 and O-ring seal 8 form, adjustment nail 6 is from left to right divided into 3 sections, the external thread section on the left side respectively, middle seal section and the adjustment section on the right, the external thread section of adjustment nail 6 is screwed in the internal thread of adjustment assembly mounting hole, the seal section of adjustment nail 6 and the right sector hole clearance fit of adjustment assembly mounting hole, the seal section of adjustment nail 6 there is annular seal groove, O-ring seal 8 is arranged in annular seal groove, the external diameter of adjustment nail 6 section of adjustment is less than the aperture of the right sector hole of adjustment assembly mounting hole, on the right-hand member of adjustment nail 6 section of adjustment and mover iron core, fit in the left side of locating cylinder 5, the left end of adjustment nail 6 external thread section stretches out the housing of linear movement pick-up 1 left, set nut 7 is screwed on the above-mentioned extension of adjustment nail 6 external thread section, the axial location of locking adjustment nail 6.
Advantage of the present invention is: propose a kind of linear movement pick-up being convenient to adjust zero-bit, enormously simplify the step of zero-bit adjustment, avoid and repeatedly dismantle linear movement pick-up, improve the work efficiency of zero-bit adjustment; Meanwhile, there is two-way adjustment function, expand setting range.One embodiment of the present of invention, prove through test, and within the time adjusting certain molded line displacement transducer zero-bit shortened to half an hour by 6 hours, the work efficiency of zero-bit adjustment improves more than 10 times.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that linear movement pick-up is installed and zero-bit adjusts at present not with zero-bit adjusting mechanism.
Fig. 2 is structure of the present invention and zero-bit adjustment schematic diagram.
Embodiment
Below the present invention is described in further details.See Fig. 2, displacement transducer 1, with mounting flange 3 on linear movement pick-up 1 housing, by screw 2, mounting flange 3 is fixed on the outside surface on carrier around linear movement pick-up mounting hole, the mover iron core of linear movement pick-up 1 has a locating cylinder 5, and locating cylinder 5 is positioned at the linear movement pick-up mounting hole on carrier, it is characterized in that: the adjustment assembly mounting hole having through track displacement transducer 1 left side and right side on the housing of linear movement pick-up 1, the axis of adjustment assembly mounting hole and the axis being parallel of linear movement pick-up 1, adjustment assembly mounting hole is the stepped hole that left sector hole footpath is greater than right sector hole footpath, in above-mentioned left sector hole, have internal thread, there is one by adjustment nail 6, the zero-bit adjustment assembly that set nut 7 and O-ring seal 8 form, adjustment nail 6 is from left to right divided into 3 sections, the external thread section on the left side respectively, middle seal section and the adjustment section on the right, the external thread section of adjustment nail 6 is screwed in the internal thread of adjustment assembly mounting hole, the seal section of adjustment nail 6 and the right sector hole clearance fit of adjustment assembly mounting hole, the seal section of adjustment nail 6 there is annular seal groove, O-ring seal 8 is arranged in annular seal groove, the external diameter of adjustment nail 6 section of adjustment is less than the aperture of the right sector hole of adjustment assembly mounting hole, on the right-hand member of adjustment nail 6 section of adjustment and mover iron core, fit in the left side of locating cylinder 5, the left end of adjustment nail 6 external thread section stretches out the housing of linear movement pick-up 1 left, set nut 7 is screwed on the above-mentioned extension of adjustment nail 6 external thread section, the axial location of locking adjustment nail 6.
