Abstract

The utility model provides a measuring tool setting device for processing rotor key slot, which is characterized by comprising tool setting boards provided with grooves and arranged at the end face of a piece to be processed, measuring posts arranged on the tool setting boards and a fixing piece. The measuring tool setting device is arranged at the end face of the piece to be processed and is not influenced by the size and the tolerance of the excircle of the piece to be processed, and can enable the chord lengths among measuring posts on the tool setting boards to be equal only by arranging the lower ends of the measuring posts on the excircle face of the piece to be processed and by simple adjustment, thereby ensuring the equation and the symmetry of key slots on the piece to be processed. The utility model has the advantages of strong commonality, simple structure, convenient and flexible operation, and the like, can enhance the processing efficiency of the key slots, improves the qualification rate of the key slots in a larger extent without causing waste key slots, reduces the cost and is particular suitable for the processing of the key slots distributed on a workpiece with a large diameter.

Description

The measurement of processing rotor keyway is to the Knife tool

Technical field

The utility model relates to a kind of measurement to the Knife tool, and the measurement that relates in particular to a kind of processing rotor keyway belongs to the machine tools technical field to the Knife tool.

Background technology

Rotor field spider be medium and the hydrogenerator of above capacity on, connect the vitals of yoke and rotating shaft, also be carrying yoke, magnetic pole weight, the vitals of magnetic pull and transmission moment of torsion.Since the rotor field spider complex structure, stressed complexity, and therefore, processing request is higher.Yoke is squeezed into stud keyway and punching keyway by magnet yoke key and is connected as a single entity with rotor field spider.Therefore, the equal indicative of rotor stud keyway and the accuracy of position will directly have influence on magnet yoke blanking sheet closed assembly process smoothly whether, also have influence on the uniformity of assembling back rotor circularity and air gap, thereby directly have influence on the overall performances such as electromagnetism, dynamic balancing of generator.For a long time, line is all adopted in the processing of this stud keyway, the processing of trial cut method, need rotational workpieces repeatedly, the repeated measurement size, time-consuming effort again, and to take for a long time that main equipment---floor type boring machine just can be finished, the one, be difficult to bring into play the working ability of main equipment, cause the waste of this device resource, the 2nd, often make the stud keyway size that processes exceed allowable error value scope, when install at the scene of being transported to, can can't assemble because of scale error, even it is multiple to return repair in shop, severe patient also can cause scrapping of this large-scale workpiece, both waste raw material, increased production cost again.Therefore, be necessary prior art is improved.

Summary of the invention

For overcoming the prior art above shortcomings, the utility model provides a kind of can guarantee machining accuracy, the reliability height, and easy to operate, high efficiency, time saving and energy saving measurement is to the Knife tool.

The utility model is finished by following technical proposal: a kind of measurement of processing rotor keyway is to the Knife tool, it is characterized in that comprising place the work piece end face which is provided with groove to knife plate, be located at measurement column on the knife plate and fixture.So that will be fixed on the work piece end face knife plate,, directly on work piece, process qualified keyway by the location and the measurement of measurement column by fixture.

Described groove on the knife plate is arranged on middle part to knife plate one side, measurement column is symmetricly set on the both sides to the knife plate groove, so that process the keyway that can satisfy form and position tolerance on the work piece that is positioned at below the tool setting plate.

Described fixture on the knife plate is comprised the sunk screw on the knife plate plate face, be located to the contiguous block of knife plate side and on the staple chord apart from adjusting nail, be located at contiguous block and the fixing nail of adjusting, be used to adjust, satisfy processing request the position of knife plate at work piece to the knife plate rear side.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can be placed on the work piece end face easily, and be not subjected to the influence of work piece excircle dimension and tolerance, only need the measurement column lower end is placed on the work piece periphery, by simple adjustment, each is equated the chord length between measurement column on the knife plate, thereby the symmetry of the five equilibrium of keyway and keyway on the assurance work piece, the utlity model has highly versatile, simple in structure, easy to operate, characteristics such as flexibly, use it can improve the keyway working (machining) efficiency, improve product percent of pass by a relatively large margin, do not go out waste product, reduce cost, particularly practical to the keyway processing that is distributed on the large-diameter workpiece.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is actual processing structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The measurement that the utility model provides is to the Knife tool, comprise place work piece A end face which is provided with groove 10 to knife plate 1, place measurement column on the knife plate 12 and fixture, wherein, groove on the knife plate 1 10 is arranged on middle part to knife plate 1 one sides, measurement column 2 is symmetricly set on the both sides to knife plate 1 groove 10, fixture on the knife plate 1 is comprised the sunk screw 3 on the knife plate 1 plate face, be located at respectively to the contiguous block 8 of knife plate 1 two sides and on staple 4 chords apart from adjusting nail 9, be located at contiguous block 6 and staple 5 to knife plate 1 rear side, adjust nail 7, be used to adjust to the position of knife plate, satisfy processing request, as Fig. 1 at work piece A, Fig. 2.

When processing stud 12 keyways 13 of rotor support power generator 11, earlier knife plate 1 is fixed on each on upper surface of stud 12 respectively by sunk screw 3, measurement column 2 lower ends are placed on the periphery of stud 12, adjust each string simultaneously apart from adjusting screw 9, chord length L between the measurement column 2 on adjacent two pairs of knife plates 1 is equated, behind the

trip bolt

4,9,7,8, behind floor type boring machine centering correction reference face B, directly on stud 12, once process keyway 13, as Fig. 3.
