Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As Figure 1-3, it is the schematic diagram of the utility model motor stator laminating tool embodiment, the motor stator is laminated
Frock can carry out stator core and laminate, and the stator core for the traction electric machine used in track traffic that is particularly suitable for use in is laminated.This implementation
Stator laminating tool in example includes bottom plate 10, mandrel component 20, pressing plate 40, latch assembly 30 and locking nut 50, wherein
Bottom plate 10 is fixed on the bottom of mandrel component 20；Mandrel component 20 includes mandrel 21 and multiple vertical rods 22, and mandrel 21 includes round platform
Portion 211 (basal diameter in the round platform portion 211 is more than top surface diameter) and the threaded shank 212 of the top positioned at round platform portion 211；Circle
Platform portion 211 has the multiple mounting grooves being uniformly distributed on the bus in the round platform portion；There is vertical face (can be for each vertical rod 22
Circular arc) and be oppositely arranged with vertical face embedded division (embedded division be in round platform portion 211 match inverted trapezoidal tilt), on
State that embedded division is corresponding with mounting groove and size is less than mounting groove；Multiple vertical rods 22 are embedded in the side of a mounting groove with embedded division respectively
Formula is attached to the round platform portion 211 of mandrel 21 and fixed by fastener；Latch assembly 30 is threadedly coupled to the threaded shank of mandrel 21
212 and the vertical rod 22 is driven to be moved up and down in mounting groove by being rotated along threaded shank 212；Pressing plate 40 is by being screwed to mandrel 21
The locking nut 50 of threaded shank 212 be assembled to the top of latch assembly 30, and the pressing plate 40 has and is placed on mandrel for compression
The pressure ring portion of stator core lamination on component (internal diameter in the pressure ring portion is more than the external diameter of mandrel component 20 and is downwardly projected).
Above-mentioned motor stator laminating tool can be made in vertical rod 22 before operation is laminated by being rotated down latch assembly 30
Lower movement, so that the circumference where adjusting the vertical face in the outside of all vertical rods 22 reaches suitable dimension (because of the bottom in round platform portion 211
The diameter in face is more than the diameter of top surface, therefore circumference reduces where the vertical face of each vertical rod 22 when moving up for vertical rod 22, conversely, vertical
Circumference where the vertical face of each vertical rod 22 when bar 22 is moved down becomes big) each vertical rod 22 is locked afterwards, proceed by stator core
Laminate operation：Stator lower platen is put on bottom plate 10 first；Then stator core lamination is placed, is reached in stator core lamination
It is required that height after, place stator top board；Then pressing plate locating ring is placed on stator top board and positioned, and will pressure
Plate 40 is placed on stator top board, and locking nut 50 is set in the threaded shank 212 of mandrel 21 and screwed, makes the pressure ring of pressing plate 40
Portion tightly pushes down the core lamination stack between stator lower platen and stator top board, completes stator and laminates flow.Laminated in dismounting
During frock (after the completion of welding), locking nut 50 is pulled down from the threaded shank 212 of mandrel 21, pressing plate 40 is then removed, then
Rotate up latch assembly 30 so that the external diameter of mandrel component 20 reduces, and complete stator core is removably.
Above-mentioned motor stator laminating tool adjusts mandrel component by the frustum cone structure of mandrel 21 with the cooperation of vertical rod 22
Periphery, is laminated so as to meet different size of a variety of motor stators.And the utility model is simple in construction, easy to operate, has
Fool proof, easy to install, quick detachable advantage is ensureing while laminating precision of stator core, is reducing the labor intensity of workman,
Improve operating efficiency.
Especially, as shown in Figures 4 and 5, the top of vertical rod 22 is in interior low outer high step-like, and positioned at the step surface in outside
It is equipped with briquetting 26 (such as each briquetting 26 can be by two tops for being bolted to vertical rod 22)；The briquetting 26 has direction
Inner side (i.e. the center of mandrel component 20) and the flange for projecting to the top of latch assembly 30, the outer rim of latch assembly 30 are located at inner side
Between the flange of step surface and briquetting 26.So, when latch assembly 30 is up, by promoting the flange of briquetting 26 so that vertical rod
22 move up along fixing groove；When latch assembly 30 is descending, by promoting the inner side step face of vertical rod 22 so that vertical rod 22 is along admittedly
Determine groove to move down.
In above-mentioned mandrel component 20, vertical rod 22 can be assembled to mandrel 21 in the following manner：By the fixation in round platform portion 211
Groove is set to cross section in inverted trapezoidal (i.e. dovetail groove), and the size of the embedded division of vertical rod 22 is less than size and the insertion of fixing groove
Portion is embedded into fixing groove together with lining bar 25；Multiple spiral shells being communicated in fixing groove are set along fixing groove in round platform portion 211
Hole, fastener is made up of bolt 23 and the lining bar 25 in groove is fixed with screw of the bolt with round platform portion 211, so that real
The fixation (fastening) of existing vertical rod 22.Because the cross section of fixing groove is in inverted trapezoidal, therefore vertical rod 22 can only detach fixation from top
Groove.
Especially, four fixing grooves can be set in the round platform portion 211 of mandrel 21, and four fixing grooves are with 90 ° of interval
Mode, which is set, (in a particular application, according to the size of laminating stator iron core, can be set three fixing grooves or more than four fixations
Groove).So, when mandrel component 20 is assembled, the embedded division of four vertical rods 22 checkpost that keeps left from top to bottom is entered into mandrel 21 first
Round platform portion 211 in uniform 4 fixing grooves, four lining bars 25 are then respectively put into the space on the right of fixing groove, four
Vertical rod 22, four lining bars 25 bottom it is concordant with the lower surface in the round platform portion 211 of mandrel 21, bolt 23 is then locked into round platform portion
Screw on and dieback lining bar 25, mandrel component 20 is completed.
To realize that stator core lamination is positioned, there is determining for protrusion on the vertical face of a vertical rod 22 in above-mentioned vertical rod 22
Position portion, and the size of the width and the groove of two between cog of stator core lamination of the location division matches.So, in stacked stator core
When piece set is attached to mandrel component, the location structure for making location division be embedded on stator core lamination, it is ensured that stator core up and down
Lamination is correctly aligned.Especially, the location division in above-mentioned vertical rod 22 can be made up of guide rod 24, correspondingly, in the vertical of vertical rod 22
Face is provided with vertical groove, and guide rod 24 is assembled to the vertical face of vertical rod 22 in the way of embedded vertical face, by this way, can basis
The different stator cores laminated change guide rod 24.Certainly, the location division in above-mentioned vertical rod 22 also can be on the vertical face of vertical rod 22
With the prominent stupefied composition of the one of vertical rod 22.
As shown in fig. 7, latch assembly 30 can use following structure：Including bearing 32, mother nut 31, anti-return nut 36, axle
