Description
Technical field
The utility model belongs to exciter commutator service technique field, especially relates to a kind of exciter commutator apparatus for examination and repair.
Background technology
Exciter carbon brush spark phenomenon often can occur in generating set in the long-play process, Symptoms is for frequently to have spark to fly out from the edge of carbon brush and commutator contact-making surface.This spark phenomenon will directly cause the commutator surface blackout, surperficial cylindricity variation, and surface roughness worsens.Carbon brush also damages contact surface because of heavy wear and groove mark occurs.Therefore must overhaul the exciter commutator, guarantee in its cylindricity Engage of standard value scope, make that carbon brush and commutator surface are optimum to be contacted.
More common processing method has several at present:
(1), exciter decomposed after, the generator amature part (weight 10000KG) that will contain commutator is transported to professed machine process unit, processes with heavy duty machine tools.This method machining accuracy is high, but workload is large, from decomposing dismounting to transportation, processing, return again and debug examination, a large amount of manpower and materials of whole process need, in addition the time also longer, expend man-hour.
(2), utilize simple hand instrument (file, scraper etc.) only to remove at the scene the devices such as hood, foundation base and carbon brush, brush holder, commutator is carried out artificial treatment.This method is saved artificial, and the time spent is shorter, but is too dependent on maintainer's experience, level of skill, can't compare with machine tooling on the precision, and quality also can't guarantee.
(3), utilize self-control maintenance utensil.Utilize at the scene lathe cutter saddle that commutator surface is carried out turning such as some maintenance unit, thereby recover the cylindricity of commutator, this method is got the advantage of two kinds of methods, both saves time, and is laborsaving again, also guaranteed simultaneously machining accuracy.But this kind method is only processed this maintenance operation of commutator cylindricity, to the later stage operation as scraping ditch, repairing service works such as scraping chamfering, still need artificial treatment, cause later stage maintenance still can't guarantee precision, maintenance is bad during fashion as a result, and it is deep mixed groove often to occur, chamfering is inconsistent, sometimes even the scratch commutator surface, destroy to repair and grind the surface, cause the repetition operation.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, can realize simultaneously the commutator apparatus for examination and repair that the maintenance of commutator surface and groove is processed.
The purpose of this utility model realizes by following technical proposals:
Exciter commutator apparatus for examination and repair of the present utility model, comprise commutator maintenance turning facility, these commutator maintenance turning facility are mainly by frame, be located at the adjustment platform on this frame, be located at the toolframe on this adjustment platform, the turning cutting tool that is located on this toolframe forms, and it is characterized in that also being provided with on described toolframe Shave tool, chamfering tool.
The blade of described Shave tool is rectangle blade, trapezoidal blade or circular arc blade.
The cutting edge of described chamfering tool is 90 °.
The blade tread of described Shave tool is 1mm, 1.5mm or 2mm, and edge length is 1mm or 1.5mm.
Advantage of the present utility model:
(1) the utility model utilizes the repacking of existing lathe cutter saddle cutter, make it to adapt to the upkeep operation of commutator surface, not only can finish the turning processing for the commutator surface cylindricity, can also carry out mechanical scraping to the mica groove of commutator, make the surperficial service work of commutator realize mechanization fully.
(2) the utility model is furnished with different Shave tools for different commutator mica grooves, and the application of dedicated tool makes machining accuracy higher.
(3) the utility model is simple in structure, and is easy to operate, is easy to on-the-spot the installation, thereby makes more high-quality and high-efficiency of service work.
(4) the utility model has been realized the entire mechanization maintenance, has reduced workman's amount of labour, reduces production costs.

Fig. 2 is three kinds of structural representations of the utility model commutator mica groove.
Fig. 3 is the structural representation of the utility model Shave tool.
Fig. 4 is the structural representation of the utility model chamfering tool.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of exciter commutator apparatus for examination and repair, comprise commutator maintenance turning facility, these commutator maintenance turning facility are mainly by frame 1, be located at the adjustment platform 2 on this frame 1, be located at the toolframe 3 on this adjustment platform 2, the turning cutting tool that is located on this toolframe 3 forms, and it is characterized in that also being provided with on described toolframe 3 Shave tool 4, chamfering tool 7.
Shown in Fig. 3 (d), (e), (f), the blade of described Shave tool 4 is rectangle blade, trapezoidal blade or circular arc blade.
As shown in Figure 4, the cutting edge of described chamfering tool 7 is 90 °.
The blade tread of described Shave tool 4 is 1mm, 1.5mm or 2mm, and edge length is 1mm or 1.5mm.
During work, at first according to the operating position fixed frame 1 of commutator 5, then the adjustment platform 2 on the frame 1 is carried out on-the-spot leveling, the level height of the toolframe 3 on the adjustment platform 2 and the height of commutator 5 work surfaces are adapted.When carrying out the turning of commutator 5 surperficial cylindricities, concrete operations and lathe turning processing circular shaft type surface of the work is similar, until whole commutator 5 working surfaces are cut, without local dent or projection and groove mark.Shown in Fig. 2 and 3, when carrying out commutator mica groove 6 and the operation of outer wall chamfering, at first select different Shave tool 4 according to the concrete shape of mica groove 6.Such as Fig. 2 (a) with 3(d), mica groove 6 is rectangle, can select blade is the Shave tool 4 of rectangle blade, it is installed on the toolframe 3, utilize manually, make blade aim at an end of commutator mica groove 6, mix up depth of cut, along the cutting edge direction at the uniform velocity feeding tool carry out scraping.After commutator 5 all axial grooves of surface are finished scraping processing one by one, increase on a small quantity again depth of cut, carry out secondary operations, three processing, until reaching the 1-1.5mm of standard technique requirement, the gash depth value gets final product.Here it should be noted that and adopt the rectangle blade to add man-hour, need increase the manufacturing procedure of one groove upper bevel again, need to change as shown in Figure 4 chamfering tool 7 again, its cutting edge is 90 ° of angles, guarantees the 45 ° of chamferings in both sides symmetrically.By that analogy, such as Fig. 2 (b) with (c), can also select trapezoidal blade Shave tool or circular arc blade Shave tool shown in Fig. 3 (e), (f) for trapezoidal and mica groove shape circular arc.
The utility model utilizes the repacking of existing lathe cutter saddle cutter, make it to adapt to the upkeep operation on commutator 5 surfaces, not only can finish the turning processing for commutator 5 surperficial cylindricities, can also carry out mechanical scraping to the mica groove 6 of commutator, make the surperficial service work of commutator 5 realize mechanization fully.Be furnished with different Shave tool 4 for different commutator mica grooves 6, the application of dedicated tool makes machining accuracy higher.
