Description
Technical field
The utility model relates to a kind of aid installed for ship steering engine and rudder stock, especially a kind of midline detect device.
Background technology
Along with the tonnage of ship constantly increases, simple grinding steering wheel rotor can not meet mounting process requirement, and this is mainly limited to and is provided with oil groove at steering wheel internal rotor, and amount of grinding is less and very easily destroy oil groove, therefore turns to grinding rudder stock gradually.For checking the contact area of steering wheel rotor and rudder stock, usually rudder stock to be horizontally fixed on support and to join oil at the region bluing with steering wheel rotor contact, then lift by crane steering wheel rotor, in moving horizontally, presetting steering wheel rotor centerline is alignd with rudder stock center line as far as possible.In the process of steering wheel rotor plug-in mounting rudder stock, need staff use clearance gauge detect steering wheel rotor and rudder stock up and down, the gap of 4, left and right, the adjustment direction of judgement steering wheel rotor.Because steering wheel rotor and rudder stock surface of contact are taper, therefore clearance gauge thickness is not adjustment amount size, thus uses clearance gauge can only judge adjustment direction and estimate adjustment amount roughly.Need four points detected to want level with vertically vertical, staff constantly detects these four points and estimates, therefore adopts clearance gauge waste time and energy and detect inaccurate simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of midline detect device, this device not only can read adjustment amount accurately, and structure is simple, is convenient to install, and the centering being applicable to different-diameter installs detection.
The technical scheme that the utility model adopts is to provide a kind of midline detect device, midline detect device, wherein: this device comprises magnet base, detection ruler, spring and screw rod, described magnet base includes rectangle cast iron block, L shaped cast iron block body and interval copper sheet and is bolted and forms, one end of described detection ruler installs spring and magnet base successively, the other end installs screw rod, and described screw rod and magnet base are for being threaded, and the middle part of detection ruler is provided with detection ruler convex shoulder.
There is a spherical hollow space between the rectangle cast iron block of described magnet base and L shaped cast iron block body, the permanent magnet rotated by knob is set in this cavity.Scale is carved with in one end of described detection ruler.Described outer screw diameter is greater than detection ruler convex shoulder diameter.
The beneficial effect of the application is that this device can read adjustment amount easily, this mainly detection ruler perpendicular to tested surface, its amount of movement is adjustment amount, and be not subject to the restriction of surface of contact tapering and measurement clearance size, can be adsorbed by knob rotating permanent magnet easily or throw off steel and iron parts, the centering piece that can meet different tapering and clearance requirement installs detection.In addition, this apparatus structure is simple, has accuracy in detection and can reach micron order, easy for installation, the effect of being convenient to production and processing.

Embodiment
By reference to the accompanying drawings midline detect apparatus structure of the present utility model is illustrated.
As shown in Figure 1, Figure 2 and Figure 3, midline detect apparatus structure of the present utility model is, this device comprises magnet base 1, detection ruler 2, spring 3 and screw rod 4, described magnet base 1 includes rectangle cast iron block 11, L shaped cast iron block body 12 and interval copper sheet 16 and is bolted and forms, one end of described detection ruler 2 installs spring 3 and magnet base 1 successively, the other end installs screw rod 4, and described screw rod 4 and magnet base 1 are for being threaded, and the middle part of detection ruler 2 is provided with detection ruler convex shoulder 21.
There is a spherical hollow space 13 between the rectangle cast iron block 11 of described magnet base 1 and L shaped cast iron block body 12, in this cavity 13, the permanent magnet 14 rotated by knob 15 is set.Scale is carved with in one end of described detection ruler 2, and described screw rod 4 external diameter is greater than detection ruler convex shoulder 21 diameter.
At midline detect device of the present utility model, be installed early stage, adjust this pick-up unit.Because detection ruler convex shoulder 21 diameter is less than screw rod 4 diameter, rotary screw 4 adjusts the overhang that detection ruler 2 is popped one's head in, to meet the use of different gap assembling.And detection ruler 2 probe is horizontal or vertical contact with assembly, therefore the change of the scale of detection ruler 2 is adjustment amount, has and measures advantage accurate, easy to use.Band colour code will can be coated with in the bottom of stretching out scale so that observe the change of detection ruler scale simultaneously.By knob 15 rotating permanent magnet 14, can firmly attract in steel and iron parts when permanent magnet 14 rotates to be when south poles is on rectangle cast iron 11 and L shaped cast iron 12 respectively in cavity 13.When the two poles of the earth, north and south of permanent magnet 14 are all in rectangle cast iron block 11 or L shaped cast iron block body 12, due to interval copper sheet 16 not magnetic conduction, the magnetic line of force is from respective cast iron inside by forming magnet short-cut path, and magnet base 1 does not externally show magnetic pole and decontrols steel and iron parts.
