Abstract
The invention discloses a motor stator core laminating tool and belongs to a tooling, aiming at providing a tool which is simple and convenient to operate, is high-efficiency and can improve the assembling accuracy of a stator core. The motor stator core laminating tool comprises a cushion plate (7) which is matched with a mandrel (8). Two positioning keys (5) which are matched with the cushion plate (7) are arranged on the surface of the mandrel (8). A screw rod (2) is arranged at the top end of the mandrel. A pressing plate (4) which is matched with the mandrel (8) and the positioning keys (5) is arranged above the cushion plate (7). A nut (3) is arranged on the screw rod (2). A pressing sleeve (9) with two through grooves (1) on the wall is arranged on the upper surface of the pressing plate (4). The motor stator core laminating tool has the advantages of simple structure, convenience in operation, high efficiency, high stator assembling accuracy and the like, and is a special tool for assembling stator cores of brushless direct-current motors.
Description
Technical field
The present invention relates to a kind of frock, relate in particular to a kind of motor stator core stack mounting tool.
Background technology
Accurate miniature specific type of electric machine is a kind of brshless DC motor, and by some inner rings, the lamination closed assembly with concave shape line embedding groove forms its stator core conventionally.Accurate miniature specific type of electric machine stator core size little (internal diameter generally between 10～40mm, axial dimension is between 10～50mm), line embedding groove is that position accuracy demand between skewed slot, each adjacent lamination line embedding groove is high, particularly stator core inner circle cylindricity and the requirement of cell wall evenness are very high, while therefore assembling, conventionally need to complete by special tooling.At present, traditional frock consists of backing plate, the mandrel that coordinates with this backing plate conventionally; Although fairly simple, the positional precision between each adjacent lamination line embedding groove and the overall dimensions of stator core are difficult to guarantee.
Summary of the invention
In view of the foregoing defects the prior art has, the present invention aim to provide a kind of simple to operation, efficiency is high, can improve the assembly tool of stator core precision.
To achieve these goals, the present invention by the following technical solutions: it comprises the backing plate coordinating with mandrel; There are two positioning keys that coordinate with backing plate on the surface of mandrel, and there is screw rod on the top of this mandrel, and the top of backing plate is the pressing plate coordinating with mandrel and positioning key, has nut on screw rod, above pressing plate, is the gland that has two grooves on wall.
Therefore compared with the prior art, the present invention, owing to having adopted technique scheme, has increased by two positioning keys on the surface of mandrel, can guarantee positional precision between adjacent lamination line embedding groove, avoid adjacent lamination line embedding groove mutual dislocation; Owing to having increased screw rod, therefore can lamination be clamped, avoid lamination resilience to cause axial dimension overproof by nut.The advantage such as that the present invention has is simple in structure, easy to operate, efficiency is high, stator assembly precision is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view in Fig. 1;
Fig. 3 is the B-B cutaway view in Fig. 1.
In figure: groove 1, screw rod 2, nut 3, pressing plate 4, positioning key 5, lamination 6, backing plate 7, mandrel 8, gland 9.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figures 1 to 3: mandrel 8 be top with the multidiameter of screw rod 2, there is keyway the both sides of mandrel 8, have positioning key 5 described in each in keyway; At mandrel 8, near the position of bottom, be the backing plate 7 coordinating with this mandrel and positioning key 5, be the pressing plate 4 coordinating with mandrel 8 and positioning key 5 above this backing plate, has nut 3 on screw rod 2; Above pressing plate 4, there is gland 9, on the wall of this gland, have two grooves 1.For the ease of taking off the stator core that closed assembly is good, between mandrel 8 and backing plate 7, gland 9 and each lamination 6, be matched in clearance, between positioning key 5 and backing plate 7, gland 9 and each lamination 6, be matched in clearance.
During use, backing plate 7 is placed on the workbench of forcing press, mandrel 8 is inserted in this backing plate, then some laminations 6 are enclosed within on this mandrel, then two positioning keys 5 are inserted respectively in the keyway of each lamination 6, mandrel 8 and backing plate 7; Pressing plate 4 is enclosed within on mandrel 8 and positioning key 5, places gland 9 and by forcing press, each lamination 6 is compacted to preliminary dimension on pressing plate 4, fastening nut 3 completes stator core closed assembly.When stator core will be exited, the present invention is taken off and is inverted on workbench from forcing press, then knock mandrel 8 bottoms and can be extracted out.
