Abstract

The utility model relates to a plumb bob, in particular to a magnetic plumb bob which can be used to find the center with the steel line for equipment installation. The utility model is mainly used to solve the technical problem of the imprecision caused by the sway of the plumb bob, at the time of the alignment of the precise equipment. The technical proposal of the utility model is that the magnetic plumb bob comprises a body of the plumb bob, which is characterized in that the body of the plumb bob is the frustum shape; the inner part of the body of the plumb bob is a communicating pore, the inner surface of which is the tapping; the communicating screw is connected in rotation with the communicating pore, and a part of the screw is stretched out of the frustum surface; the downside of the screw is a conical tip; powerful magnetic ring is sleeved in the part of the screw stretched out of the frustum surface. The utility model is mainly used to find the center for equipment installation with high demand of the precision.

Description

A kind of magnetic line is weighed down

Technical field:

The utility model relates to a kind of line and weighs down, and particularly a kind of equipment that is used for is installed the magnetic line bob of hanging steel wire alignment use.

Background technology:

Cold rolling finishing zone circle shear is a kind of high-precision equipment, is used to be with steel plate to cut: the limit finishing.Disc shear cutter head main shaft end play 0.003mm, radial play 0.003mm, about two circle shears quite responsive to machining center linear distance error, the accuracy requirement height, the on-the-spot installation when adjusting, after overhaul with reference to Fig. 1, because of center line steel wire 2 longer, cooling fan blows and near miscellaneous equipment operation, causes that line weighs down body 1 and rocks, and influences measuring accuracy.

Summary of the invention:

The purpose of this utility model provides a kind of magnetic line that can improve line bob degree of stability and weighs down, and mainly solves when the precision equipment centering, and line weighs down to rock to cause measures coarse technical matters.

The technical solution of the utility model is: a kind of magnetic line is weighed down, comprise that line weighs down body, it is characterized in that, it is taper type that line weighs down body, online bob body core is a through hole, the inside surface tapping, and the perforation screw rod is screwed in the through hole and has one section to stretch out the frustum face, the screw rod lower end is socketed with the strong magnet ring for the awl point at the spiro rod section that stretches out the frustum face.

Screw rod lower end awl point has nitriding layer, and magnet ring end face and iron plate surface distance 4-5mm during the location can have enough magnetic force stability lines to weigh down and rock.

Description of drawings:

Fig. 1 weighs down profile for traditional wire

Fig. 2 is the utility model structural representation

Among the figure: the 1-line weighs down body, 2-center line steel wire, 3-screw rod, 4-strong magnet ring.

Embodiment:

With reference to Fig. 2, a kind of magnetic line is weighed down, and comprises that line weighs down body 1, and it is taper type that line weighs down body 1, online bob body core is a through hole, the inside surface tapping, perforation screw rod 3 is screwed in the through hole and has one section to stretch out the frustum face, and screw rod 3 lower ends are the awl point, be socketed with strong magnet ring 4 at the spiro rod section that stretches out the frustum face, screw rod lower end awl point has nitriding layer, and magnet ring end face and iron plate surface distance 4-5mm during the location can have enough magnetic force stability lines to weigh down and rock.During concrete operations, about two circle shears very high to the distance between center line accuracy requirement, error≤0.01mm, center line steel wire hanging wire weighs down, and the awl point is aimed at steel construction bottom of foundation datum line, and other line of center line weighs down the calibration processing roller simultaneously, jockey pulley, centers such as coiling machine.Each line weighs down the magnet ring of packing into then, interior hexagonal pyramid point screw rod retreats, and makes magnet ring end face distance face 4mm, stablizes and does not rock, cutter tilt face length end, short end weigh down vertical line with thousand fens sounding rods to the center line line respectively and measure, light emitting diode is glittering when touching, and operates absolute error meticulously and is controlled in the 0.01mm, and the awl point finish grindes through nitriding, hardness HRC58-60, the durability degree of accuracy improves, and finishes smoothly to install after the overhaul and adjusts, and reaches the high precision technology requirement.

Claims (2)

1, a kind of magnetic line is weighed down, comprise that line weighs down body, it is characterized in that, it is taper type that line weighs down body, online bob body core is a through hole, the inside surface tapping, and the perforation screw rod is screwed in the through hole and has one section to stretch out the frustum face, the screw rod lower end is socketed with the strong magnet ring for the awl point at the spiro rod section that stretches out the frustum face.

2, a kind of magnetic line according to claim 1 is weighed down, and it is characterized in that, screw rod lower end awl point has nitriding layer.
