Description
Technical field
The present invention relates to, for power transformer, reactor, the aluminum barricade assembly tooling of converter power transformer, be specifically related to
A kind of screening cover planisher.
Background technology
In order to reduce stray loss in large-scale power transformer, reactor, the change of current become, at fuel tank internal equipped with shielding dress
Putting, original structure typically uses copper shield, in recent years in order to reduce copper shield welding and the polishing a large amount of dust of generation and toxic gas
Murder by poisoning operator, aluminum shielding construction is promoted the use of, and does not weld and polishing operation, is to use the parts such as stud and nut solid
Fixed.
Aluminum shielding fixed structure is shown in the bottle-cover-shape zero that the stainless steel part that middle screening cover is thickness only 0.8 millimeter is stamped to form
Part, periphery has equally distributed eight to fall wing, squeezes into after in groove the elastic force by wing and fixes screening cover, sees Fig. 1.Install and need
Hammer driven, can fixation, but concavo-convex vestige easily occurs, it is impossible to ensure flat smooth.
Summary of the invention
For the problems referred to above, the present invention provide one can by screening cover fixation and ensure screening cover surfacing smooth
Screening cover planisher.
For solving problem above, the technical scheme that the present invention takes is: a kind of screening cover planisher, including what Open Side Down
For the first groove of clamping screening cover, the first groove upper surface is vertically connected with handle, is provided with for pushing away in handle bottom
The pressing device of pressure screening cover, described pressing device is positioned at the first groove and its protruded length less than the first groove height.Will
Screening cover is placed in the first groove, and the first groove edge withstands on eight of screening cover and falls plane on wing, taps gently with hand hammer
Upper handle portion, eight energy of falling wing uniform stresseds, make screening cover enter in aluminum shielding groove, plane and aluminum barricade surface on wing
Concordant, and screening cover upper surface is higher than aluminum shielded surfaces about 3mm.The uniform stressed of falling wing is avoided that owing to mismachining tolerance causes herein
Unbalance stress, make the most smooth being absorbed in aluminum barricade groove of screening cover, for next step tie foundation basis.Described pushes away
Press-fit the SOC.HD. cap screw being set to end insertion handle bottom.The spanner space of fastening soket head cap screw is little, fastens convenient and reliable.
Described first groove includes the two-layer groove of connection, and lower floor is the circular groove that internal diameter is slightly larger than screening cover external diameter,
Upper strata is the groove for installing the soket head cap screw being connected with handle.
The design of circular groove is to allow the stress of falling wing so that it is abduction increases and aluminum shields the frictional force between groove, from
And when ensureing transport and run, loose or dislocation phenomenon will not occur, if without circular groove, it is probably shielding cover upper planar surface and is subject to
Power, does not has the effect increasing frictional force.Described handle is connected to the home position of circular groove upper surface.Handle is with circular
Groove is coupled by soket head cap screw, and advantage is that the little compact conformation of soket head cap screw installing space is reliable.Circular groove refers to
Process on nylon column, have two-layer groove.Ground floor is slightly larger than screening cover external diameter and position, screening cover rigidity preferable outer ring
Put contact pressure, be unlikely to deform；Middle one layer of deeper groove, centre is through hole, for installing the interior hexagonal coupled with handle
Screw, when pressing screening cover, central rigid poor position, only by air pressure, will not produce transition deformation simultaneously.A kind of screen
Covering lid planisher, including a cylinder, described cylinder upper surface is vertically connected with handle, and cylinder lower surface is smooth.For tie
Device, as long as ensureing that the surface contacted with screening cover is smooth.
The second groove is offered in central area, cylinder lower surface, and described second groove diameter is less than screening cover diameter.At cylinder
Center machined the second groove so that it is center weakness zone does not stresses, so that coplanar flat is smooth on screening cover.
Actual whole operation is in two steps: the first step, squeezes into；Second step, ties.
Second step changes into be tied by nylon column, nylon cylinder lower surface alignment shielding cover upper planar surface, raps handle with hand hammer
Top, ties first step shielding cover upper planar surface completely higher than aluminum shielded surfaces 3mm, and making spacing is 0, is squeezed into completely by screening cover
In groove, shielding cover upper planar surface should the deformation of smooth no concave-convex.The plane poor in order to avoid shielding cover upper planar surface intermediate intensity is subject to
Force deformation, machined groove in the center of nylon column so that it is center weakness zone does not stresses, so that shielding cover upper planar surface
Flat smooth.
The invention has the beneficial effects as follows, make aluminum shielding easier for installation fast, promote work efficiency；Ensure installation accuracy
And quality, it is to avoid when the later stage is run, there is the improper concavo-convex electric field inhomogeneities caused in screening cover, and runs or transport vibrations
The defect such as get loose caused, can improve the quality of product.

Detailed description of the invention
A kind of screening cover planisher, as in figure 2 it is shown, include the first groove 1 for clamping screening cover that Open Side Down, the
One groove 1 upper surface is vertically connected with handle 2, is provided with the soket head cap screw 4 for pushing screening cover 3 in handle 2 bottom, and six
Angle screw 4 is positioned at the first groove 1 and its protruded length less than the first groove 1 height.Described first groove 1 includes the two of connection
Layer groove, lower floor is the circular groove that internal diameter is slightly larger than screening cover 3 external diameter, upper strata be for install be connected with handle 2 in six
The groove of angle screw 4.Described handle is connected to the home position of the first groove 1 upper surface correspondence circular groove.
A kind of screening cover planisher, as it is shown on figure 3, include a cylinder 5, described cylinder 5 upper surface is vertically connected with handle
2, the second groove 6 is offered in central area, cylinder 5 lower surface, and described second groove 6 diameter is less than screening cover 3 external diameter.
Above-mentioned cylinder is nylon column cylinder, and above-mentioned groove is the groove being opened in nylon column.
Use process:
(1) by nylon column plane towards handle, with soket head cap screw, handle 2 is connected fastening with nylon column, during for squeezing into
Installation method；
(2) by screening cover 3 opening surface outwardly, plane puts into nylon column groove, and nylon column is withstood in eight ends of falling wing
Plane；
(3) screening cover opening surface is put into aluminum barricade groove, rap handle end with hand hammer, note observing screening cover
Should enter in groove the most easily, become big situation if any the stress such as bite or inclination, again squeeze into after ascertaining the reason, it is to avoid
There is the non-stress of wing or the situation of the torsional deformation of screening cover own.
(4) by nylon column concave surface towards handle, with soket head cap screw, handle is connected fastening with nylon column, (is used for tying
Device, as long as ensureing that the surface that contacts with screening cover is smooth) for tying time installment state；
(5) cover in the shielding cover upper planar surface having been inserted into by nylon column plane, rap handle end with hand hammer, lift inspection
Look into whether to shield and be stamped deformation of unevenness, again tap till making it concordant with aluminum barricade.
