Abstract

The utility model discloses a locating device for assembling a generator, which comprises a bottom board, wherein a locating hole contrapuntal with a locating pin on a front bracket of the generator is arranged on the bottom board. Two parallel brackets are arranged on the bottom board, and a spacing plate which is parallel to the bottom board is sheathed with spacing pins vertically arranged on the top of the bracket. The spacing plate can singly rotate around every spacing pin, and a spacing hole corresponding to a generator rotor is arranged on the spacing plate. The device can solve the locating problem of every main part in the assembling process of a generator, not only greatly raises the work efficiency, reduces the workmen's labor intensity, but also prevents the phenomenon that parts are damaged in the manual locating process.

Description

A kind of positioner that is used for the generator assembling

Technical field

The utility model relates to the positioner in a kind of product assembling process, relates to a kind of positioner that is used for the generator assembling particularly.

Background technology

Generator mainly is made up of stator, rotor, front rack, tail-bracket, and these parts are realized mutual connection and rotation by bearing, alignment pin etc.The assembling process of generator, its essence are exactly the process that above-mentioned parts are made up on request.This combination at first needs the mode by pin and hole or dead eye between any two is bonded together, and is fastening again, and then other smallclothes are installed.Because main parts such as the front rack of generator, tail-bracket are big and heavy, for the bearing pin that makes one of them main part enters the pin-and-hole of another main part, the workman often will be taken many twists and turns, even needs two people to cooperate to finish.And when assembling, the location of each main part is pure in manually finishing, and its polarization is very poor, is not easy assembling on the one hand, will spend many times in the process of contraposition, inefficiency; On the other hand, in contraposition process repeatedly, the increased frequency that contacts between the parts very easily scratches parts, influences product quality.

Summary of the invention

At the deficiency that has artificial location in the above-mentioned prior art generator assembling process, the purpose of this utility model just provides a kind of positioner that assembles usefulness specially at generator.

The technical solution of the utility model is achieved in that a kind of positioner that is used for generator assembling, comprises base plate, base plate be provided with the generator front rack on the location hole of alignment pin contraposition.Base plate is provided with two parallel supports, and one is parallel to the limiting plate and the vertical spacer pin socket that is provided with of a top of the trellis of base plate.Limiting plate can rotate around each spacer pin separately, and limiting plate is provided with the spacing hole corresponding with generator amature.

The utility model be provided with on the base plate with the generator front rack on the location hole of alignment pin contraposition, solved the location and the support problem of front rack, for the assembling of other parts of generator provides the foundation.The spacing hole corresponding with generator amature guaranteed that then rotor is in place on the limiting plate, and be not oblique partially, and this is the key of generator life-span and usefulness just.Use this device can effectively solve the orientation problem of each main part in the generator assembling process, operating efficiency is improved greatly, alleviated working strength of workers, but also stopped the appearance of parts scuffing phenomenon in the artificial position fixing process.

The utility model also has simple in structure, the characteristics that are easy to grasp.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

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

Fig. 3 is the installing and locating schematic diagram of the utility model to generator.

Fig. 4 is the vertical view of Fig. 3.

Embodiment

Because the utility model is to assemble usefulness at generator specially, its design must be with the parts interwoveness of generator.From Fig. 3, Fig. 4 installing and locating schematic diagram as can be seen, generator mainly is made up of stator 13, rotor 14, front rack 15, tail-bracket 16, and its location, installation are mainly for them.

Referring to Fig. 1, Fig. 2, as can be seen, the utility model mainly is made up of base plate 1, support 2, spacer pin 3 and limiting plate 4 from the figure.Base plate 1 is the installing and locating benchmark of whole frock, be fixed on the feet 5, be provided with two sleeves 6 with interference fit on the base plate 1, the size of sleeve hole 7 is corresponding to two alignment pins on the generator front rack 15, to realize the location to generator front rack 15, two alignment pins on the immediate shipment timing generator front rack 15 insert in the sleeve hole 7.Support 2 is used for support limit plate 4, is cylindrical structure, and its quantity is two, and is parallel to each other.The two ends of each support 2 all are fixed on the flange, and end flanges 8 is fixed on the base plate 1 by screw 9 and pin 10 under the support.3 pairs of limiting plates 4 of spacer pin play the role of positioning, and its quantity is corresponding with support 2, are two also, are separately fixed on the support upper flanges 11.14 position-limiting actions of 4 pairs of generator amatures of limiting plate, the centre has spacing hole 12, and this spacing hole 12 is corresponding with the rotating shaft of generator amature 14, is used for shaft set in this hole.Spacing hole 12 both sides are provided with the installing hole corresponding with spacer pin 3, and limiting plate 4 is sleeved on two spacer pins 3 by the installing hole on it, and promptly the installing hole that stretches out on the limiting plate 4 of spacer pin 3 connects limiting plate 4.Limiting plate 4 all can rotate around each spacer pin 3 separately.For making things convenient for the workman to assemble and the parts of taking, limiting plate 4 can upwards extract breaking away from one of them spacer pin 3, and removes around another spacer pin 3 rotations, and therefore, two spacer pins 3 have the branch of length.

Support of the present utility model is fixing by last lower flange and base plate and spacer pin; but be not limited thereto; also can directly be welded on the base plate such as the support lower end, the support upper end can or directly process a spacer pin with the spacer pin welding, also falls into protection range of the present utility model.

Simultaneously; the utility model is to realize by the sleeve on the base plate to the location of two alignment pins on the generator front rack; obviously; this structure also can replace with the location hole that directly is provided with on the base plate; as long as the size of this location hole is corresponding with alignment pin on the front rack, this does not break away from protection range of the present utility model equally.

Adopt this positioner, the assemble flow of generator is as follows:

1, carriage location.Cleaning front rack part aligns the front rack part of having good positioning respectively with two location holes on two alignment pins (installing in advance on the product) on the front rack part and this device base plate.

2, rotor is installed.With rotor (bearing 6306 is installed on the armature spindle in advance) front rack of packing into, the rotor bottom end bearing is to the front rack spindle hole, and the rotor upper end is manually knocked with copper rod with the location, location, hole of this device limiting plate in the upper end, and rotor is in place.

3, stator is installed.With the insertion of aliging respectively of two pin-and-holes of two alignment pins (installing in advance on the product) and front rack part on the stator part, manually knock the stator upper end with copper rod, stator is in place.

4, tail-bracket is installed.In advance bearing 6102 is pressed in the tail-bracket part spindle hole, the tail-bracket dead eye is aimed at armature spindle, armature spindle is located with limiting plate simultaneously, manually knocks the tail-bracket upper end with copper rod, and tail-bracket is seated.

5, the installation of other parts be connected.Connect each several part with special bolt.Take off portion's dress assembly, portion's dress finishes.
