Abstract
The utility model discloses a pressing mold for vertically assembling a cast-aluminum rotor and a rotary shaft. The pressing mold comprises an upper die and a lower die which are arranged at an upper position and a lower position respectively. The upper die is composed of a sleeve arranged at an upper end of the rotary shaft, and the internal diameter of the sleeve is consistent with the external diameter of a shaft body at the upper end of the rotary shaft. The lower die comprises a pedestal and a first pipe body arranged on the pedestal. The internal diameter of the first pipe body is larger than the internal diameter of a cast-aluminum rotor body, and the external diameter of the first pipe body is smaller than the internal diameter of a fin ring at an end part of the cast-aluminum rotor. A lower end face of the cast-aluminum rotor body and an upper end face of the first pipe body are in abutted joint, and the axis of the lower end face of the cast-aluminum rotor body is consistent with the axis of the upper end face of the first pipe body. With the pressing mold, the cast-aluminum rotor and the rotary shaft can be fixed firmly, and co-core assembly of the cast-aluminum rotor and the rotary shaft is realized. In the operation, the upper die is pressed downwardly to press the rotary shaft into the cast-aluminum rotor so that the qualified rate of rotor assembly is raised and production efficiency of a motor is improved.
Description
Technical field
The utility model relates to a kind of cast-aluminum rotor and the vertical assembling pressing mold of rotating shaft.
Background technology
Rotor is obtained by hot interference fit frock by cast-aluminum rotor and rotating shaft, the hot interference frock of tradition cast-aluminum rotor and rotating shaft adopts horizontal frock mode to carry out mostly, be that the axis of cast-aluminum rotor and rotating shaft is in respectively and carries out frock in the level, though this frock mode is simple to operate, but it is difficult in operating process guarantee that the axis of cast-aluminum rotor and rotating shaft is in parastate constantly, be difficult in the official hour both assemblings be finished, locking phenomenon appears easily, be that both frocks are incomplete, after cast-aluminum rotor cools off fully, both will assemble after can't separating again, therefore a large amount of waste products occur, make the production cost of motor increase.
Summary of the invention
The purpose of this utility model provides a kind of cast-aluminum rotor and the vertical assembling pressing mold of rotating shaft, can realize the same core frock of rotating shaft and cast-aluminum rotor, prevents locking phenomenon, improves the rate of finished products of rotor frock.
For achieving the above object, the utility model has adopted following technical scheme: the vertical assembling pressing mold of a kind of cast-aluminum rotor and rotating shaft, it is characterized in that: comprise the upper and lower corresponding upper and lower mould of arranging, described patrix is that a sleeve pipe that is set in the rotating shaft upper end constitutes, and the internal diameter of sleeve pipe is consistent with the external diameter of rotating shaft upper end axis body; Described counterdie comprises first body that arranges on base and the base, the internal diameter of first body is greater than the external diameter of cast-aluminum rotor body internal diameter and first body internal diameter less than cast-aluminum rotor end fin ring, the lower end surface of cast-aluminum rotor body and the upper end end face of first body lean fit and both axis consistent.
The beneficial effects of the utility model are: by the mould of said structure, can carry out good fixing to cast-aluminum rotor and rotating shaft, guarantee that cast-aluminum rotor and rotating shaft are with the core frock, during operation, make rotating shaft be pressed in the cast-aluminum rotor to get final product by pressing down patrix, improve the qualification rate of rotor assembling, improve the productivity effect of motor.

Fig. 2 carries out the structural representation of frock for the utility model countershaft and cast-aluminum rotor;
Fig. 3 is the structural representation of rotating shaft;
Fig. 4 is the structural representation of cast-aluminum rotor.
Embodiment
The purpose of this utility model is to provide a kind of axis of realizing rotating shaft and cast-aluminum rotor frock that is parallel to each other, prevent cast-aluminum rotor and the vertical assembling pressing mold of rotating shaft of locking phenomenon, its scheme of taking as shown in Figure 1, 2, the vertical assembling pressing mold of a kind of cast-aluminum rotor and rotating shaft, comprise the upper and lower corresponding upper and lower mould of arranging 11,12, described patrix 11 is that a sleeve pipe that is set in rotating shaft 21 upper ends constitutes, and the internal diameter of patrix 11 is consistent with the external diameter of rotating shaft 21 upper end axis bodies; Described counterdie 12 comprises the first body 12a that arranges on base and the base, the internal diameter of the first body 12a is greater than the external diameter of cast-aluminum rotor body 22a internal diameter and the first body 12a internal diameter less than cast-aluminum rotor end fin ring 22b, the lower end surface of cast-aluminum rotor body 22a and the upper end end face of the first body 12a lean fit and both axis consistent.Rotating shaft 21 two ends are according to its rigging position on motor case again, can be divided into rotating shaft front end and rotating shaft rear end, the rotating shaft front and back ends is step axle shape structure, its shaft rear end is followed successively by rotating shaft thread segment 21c and is used for bearings mounted shaft bearing section 21b by roller end to rotating shaft body, and the rotating shaft changeover portion 21a between shaft bearing section 21b and the rotating shaft body, specifically as shown in Figure 3.The utility model in use, preferably with the rotating shaft front end as for upside, that is aforesaid upper end of matching with patrix 11.When assembling, by the fixing and location of 12 pairs of cast-aluminum rotors 22 of counterdie, guarantee that rotating shaft 21 and cast-aluminum rotor can press-fit with core, improve the qualification rate of rotor frock like this.Because the fin on the cast-aluminum rotor is arranged in the form of a ring at cast-aluminum rotor body 22a two ends, therefore regard the fin at cast-aluminum rotor body 22a two ends as a ring-shaped article with inside and outside footpath herein and treat, be i.e. fin ring 22b described above.
When concrete operations, it is of crucial importance that rotating shaft 21 press-fits the location of back in cast-aluminum rotor 22, those of ordinary skills can be according to the size of rotating shaft 21 and cast-aluminum rotor 22 during concrete operations, choose the first body 12a of corresponding height, make when rotating shaft 21 is seated, the last portion of the rear end of rotating shaft 21 is lucky and base is inconsistent, thereby realize the location of rotating shaft 21, preferably implement according to following scheme in the utility model, described base is that the second body 12b that the one and first body 12a arranges with core constitutes, the internal diameter of the described second body 12b is between the external diameter of the external diameter of shaft bearing section 21b and rotating shaft changeover portion 21a, and the table top 21d on the rotating shaft periphery wall between described shaft bearing section 21b and the rotating shaft changeover portion 21a and the upper end end face of the second body section 12b lean to fit and position.Upper end end face by table top 21d and the second body section 12b leans to fit and positions, and avoids end, the rear end portion of rotating shaft 21 and base joint and causes the damage of rotating shaft thread segment 21c, protects rotating shaft 21.
Further scheme is, is detachable the connection between the described first body 12a and the second body 12b.The tube chamber of described patrix 11 is step axle shape.Being detachable the connection between the first body 12a and the second body 12b, mainly is the first body 12a of being convenient to change different size, realizes the rotating shaft 21 of different model and the frock of cast-aluminum rotor.
In a word, the utility model can effectively be realized the same core frock of rotating shaft and cast-aluminum rotor preventing locking phenomenon, improves the rate of finished products of rotor frock and reduces the production cost of motor.
