Description
Technical Field
The invention relates to the technical field of flange hole positioning, in particular to a bolt hole positioning device for an oversized flange and a using method of the bolt hole positioning device.
Background
When the large-scale full-rotation device is installed, the flange of the base panel is required to correspond to the flange of the full-rotation module to be installed, and the bolt butt joint of the flange of the full-rotation module is completed.
The conventional method for the situation is to manufacture a 1:1 template tool and perform film copying and drilling on site, but when the diameter of a full-rotation propeller is too large, the manufacturing of the 1:1 template tool is limited by a plate gauge and the peripheral matched processing capacity, and the method cannot be realized because the domestic plate gauge is 2400mm in size at most; and when carrying out the position location of bolt hole, the precision of bolt hole is usually higher, and the diameter of base panel flange is too big again, and the diameter measurement that conventional use can't carry out the location to diameter measurement has measurement error.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides a positioning device for positioning bolt holes of a large-size flange, which is low in manufacturing cost, simple to operate and capable of accurately measuring and determining the positions of the bolt holes, and a use method thereof.
In order to achieve the above purpose, the invention adopts the following technical scheme: the bolt hole positioning device of the extra-large-size flange comprises a right-angle pitch circle drawing gauge, a short arc plate positioning tool, a full-rotation module flange and a base panel flange, wherein the right-angle pitch circle drawing gauge comprises a guide rod, a first sliding sleeve is horizontally sleeved on the guide rod, a first locking screw is screwed on the top of the first sliding sleeve, a vertical rod is vertically downwards fixedly connected to the bottom end of the first sliding sleeve, a guide plate is vertically sleeved on the vertical rod, a second locking screw is horizontally screwed on the guide plate, a vertical second sliding sleeve is fixedly connected to the end head of the guide rod, an adjustable drawing needle is sleeved in the second sliding sleeve, and a third locking screw is screwed on the right side of the second sliding sleeve; the short arc plate positioning tool comprises a short arc plate and a tiger mouth clamp, wherein the short arc plate is sampled on a full-rotation module flange, a through hole is formed in the short arc plate, the diameter and the position of the through hole are manufactured by taking bolt hole data of 30 degrees on an arc of the full-rotation module flange as templates, pitch arc lines passing through the circle centers of all the bolt holes are marked, the tiger mouth clamp comprises a U-shaped body, the upper port of the tiger mouth clamp is vertically and spirally connected with a fixing screw, the bottom end of the fixing screw is fixedly connected with an upper pressing plate downwards, and the lower port of the tiger mouth clamp is fixedly connected with a lower pressing plate upwards.
The main principle of the right-angle pitch circle compass is that when the chord length is unchanged, the distance from the chord center to the circle center is always unchanged, and the distance from the chord center to the arc center corresponding to the chord is also always unchanged, wherein the chord length is the length of the guide plate, and compared with the diameter measurement, the method is more convenient and has higher accuracy; the short arc plate positioning tool utilizes the bolt holes on the connecting flange of the full-rotation module to be equally arranged, and the short arc plate is continuously transferred and operated, so that the positioned bolt holes can be used for positioning the next bolt hole by matching the short arc plate with the tiger mouth clamp, and all the bolt hole positions can be determined only by simple repeated steps.
Preferably, the guide rod, the upright rod and the adjustable drawing needle are all non-revolving bodies.
The guide rod of the non-revolving body section limits the movement direction of the first sliding sleeve, so that the first sliding sleeve can only transversely slide left and right along the guide rod, and the upright rod and the guide plate are always kept on a vertical plane in the movement process, so that the first sliding sleeve is prevented from rotating to cause the guide plate to slide along the inner wall of the flange of the base panel to generate position deviation, and the upright rod and the non-revolving body of the adjustable drawing needle have similar non-revolving body effects with the guide rod, so that errors caused by position dislocation are prevented.
Preferably, the guide plate is bilaterally symmetrical with respect to the upright and is perpendicular to the guide rod and the upright.
Preferably, the guide plate is rounded on the side opposite to the second sliding sleeve.
Preferably, the adjustable drawing needle is perpendicular to the guide rod and parallel to the upright rod.
Preferably, the guide rod is provided with graduations.

step two, loosening a second locking screw, moving a right-angle pitch circle gauge onto a base panel flange, tightly attaching two fillets on one side, close to a second sliding sleeve, of a guide plate to the inner wall of the base panel flange, adjusting and enabling pins of an adjustable drawing needle to be in contact with the upper end surface of the base panel flange, tightening the second locking screw, at the moment, measuring the distance delta L between the pins of the adjustable drawing needle and the inner wall of the base panel flange by using a micrometer, rechecking whether the delta L and the delta r are equal or not, if errors exist, loosening the first locking screw while keeping the guide plate attached to the inner wall of the base panel flange, finely adjusting a guide rod, tightening the first locking screw, and repeatedly measuring delta L until the difference between the delta L and the delta r is within the error range, and locking the first locking screw;
checking and ensuring that all the locking screws are screwed, pressing the guide plate, keeping the contact surface of the guide plate and the inner wall of the base panel flange tightly attached, and holding the adjustable drawing needle to draw a section circle line on the base panel flange;
measuring the position of a ship center line by using a total station, projecting the position onto a flange surface of a base, taking the intersection point of a projection line and a pitch line drawn by a right-angle pitch circle as the position of a first bolt hole, drilling the first hole by using a hollow magnetic drill, placing a short arc plate on the flange of the base after the drilling is finished, correspondingly placing the bolt hole at the leftmost end of the short arc plate and the position of the first bolt hole determined by the total station, and then controlling the short arc plate to rotate around the center of the first bolt hole until the pitch arc line of the short arc plate and the pitch circle drawn by the right-angle pitch circle completely coincide;
step five, attaching the lower pressing plate of the tiger mouth clamp to the lower surface of the flange of the base panel, and turning the knob fixing screws until the upper pressing plate is attached to the short arc plate and compacted;
step six, drilling holes along the bolt holes on the short arc plate, unscrewing the fixing screws after the drilling is completed, adjusting the position of the short arc plate, enabling the position of the last drilled hole to correspond to the position of the bolt hole at the leftmost end on the short arc plate, controlling the short arc plate to rotate around the center of the first bolt hole until the pitch arc line of the short arc plate is completely overlapped with the pitch line drawn by the right-angle pitch circle drawing, and repeating the operation of the step five after the position is determined;
and step seven, repeating the step six until all drilling work is completed.
