Abstract
The invention discloses an axis seeking method for an old shaft of a centrifugal blower. The method includes the following technological steps that firstly, one end of a main shaft to be repaired is clamped through a chuck, a middle frame is arranged in the middle position of the main shaft to be repaired in a sleeving manner, and three setting bolts on the middle frame abut against the main shaft; secondly, an ejecting pin arranged on an ejecting pin tailstock abuts against the other end of the main shaft to be repaired, and bases of two dial indicators are both adsorbed to the ejecting pin tailstock; thirdly, the two dial indicators are used for measuring the actual deviation values of the circle at the shaft end in the X direction and the Y direction; and fourthly, the main shaft to be repaired is reversed, the steps are repeated, and a center hole of the other end is sought. The axis seeking method for the old shaft of the centrifugal blower is simple, fast, practical, reliable, high in operability, capable of reducing the rate of considered errors in operation, and high in efficiency.
Description
Technical field
The invention belongs to air blast and repair field, particularly a kind of old axle for centrifugal blower looks for axle center method.
Background technology
For centrifugal blower, rotor is the key position of centrifugal blower, and it is by connecting motor High Rotation Speed, to air work.Rotor is made up of many parts: main shaft, impeller, key and balancing frame etc.On rotor, each parts are enclosed within main shaft and do high-speed motion with axle.Main shaft is as the key components and parts accepting Power output, and its effect nature is self-evident.After a long time use, if recoverable trickle damage has appearred in main shaft, this situation has not needed more to renew main shaft, as long as repair damaged location blower fan usually.Main shaft is when repairing, and what first will do is look for axle center, and after the old axial length time uses, because reasons such as corrosion, subtle flow, centre hole destructions, needing punches again looks for axle center.At present, for main shaft punching look for the method in axle center to be mainly bus method, this method to main spindle table surface roughness and circularity Geometrical Tolerance Principle very high, and the required precision for lathe is also strict, bus method looks for axle center step complicated, and easily make mistakes, efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of old axle for centrifugal blower and looks for axle center method, and method is simple, quick, practical, reliable, workable, reduces to think the probability of error in operation, and efficiency is high.
For realizing above-mentioned technique effect, the invention provides a kind of old axle for centrifugal blower and look for axle center method, it comprises following processing step:
One, clamped by chuck main shaft one end to be repaired, middle frame is enclosed within main shaft centre position to be repaired, and three tight fixed bolts on middle frame withstand on main shaft, and three tight fixed bolts lay respectively at the trisection of middle frame circumferentially;
Two, the other end of main shaft to be repaired is withstood by the thimble be arranged on thimble tailstock, the base of two dial gauges is all adsorbed on thimble tailstock, one of them dial gauge is adjacent to main shaft upper axial end to be repaired, another dial gauge is adjacent to main shaft diameter to be repaired to upper end, is set to 90 degrees between two dial gauges;
Three, the round X of two dial gauges measurement axle heads and Y-direction is used to depart from actual value respectively, and record data, when the data of dial gauge record are greater than setting value, the position of middle frame supports main shaft is adjusted in adjustment, continue to measure, until the actual value that departs from measured is less than setting value, drill centers again;
Four, main shaft to be repaired is commutated, repeat above-mentioned steps and look for other end central hole location.
A kind of old axle for centrifugal blower proposed by the invention looks for axle center method, and method is simple, quick, practical, reliable, workable, reduces to think the probability of error in operation, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation that time set surveyed by main shaft to be repaired.
Fig. 2 is the perspective view that time set surveyed by main shaft to be repaired.
Fig. 3 is determination data schematic diagram.
Detailed description of the invention
See accompanying drawing, a kind of old axle for centrifugal blower looks for axle center method, and it comprises following processing step:
One, clamped by chuck 1 main shaft 2 one end to be repaired, middle frame 3 is enclosed within main shaft centre position to be repaired, and three tight fixed bolts on middle frame withstand on main shaft, and three tight fixed bolts lay respectively at the trisection of middle frame circumferentially;
Two, the other end of main shaft to be repaired is withstood by the thimble 5 be arranged on thimble tailstock 6, the base of two dial gauges 4 is all adsorbed on thimble tailstock, one of them dial gauge is adjacent to main shaft upper axial end to be repaired, another dial gauge is adjacent to main shaft diameter to be repaired to upper end, is set to 90 degrees between two dial gauges;
Three, the round X of two dial gauges measurement axle heads and Y-direction is used to depart from actual value respectively, and record data, when the data of dial gauge record are greater than setting value, the position of middle frame supports main shaft is adjusted in adjustment, continue to measure, until the actual value that departs from measured is less than setting value, drill centers again;
Four, main shaft to be repaired is commutated, repeat above-mentioned steps and look for other end central hole location.
If beating of drawing requirement main shaft is less than 0.01mm, and old axle actual axle center deviation theory value be respectively+X-direction offset by 0.2mm,-Y-direction offset by 0.1mm, the data of two dial gauge physical records offset by 0.4mm for+X-direction,-Y-direction offset by 0.2mm, the position of the supports main shaft of adjustment middle frame, edge+X-direction skew-0.2mm ,-Y-direction offset by-0.1mm.Behind the Support Position of adjustment middle frame, wheel measuring again, if the data value of dial gauge record is greater than 0.01mm, then continues to use said method adjustment, until meet the demands, and finally drill centers again.
A kind of old axle for centrifugal blower proposed by the invention looks for axle center method, and method is simple, quick, practical, reliable, workable, reduces to think the probability of error in operation, and efficiency is high.
