Description
Technical field
The utility model relates to motor, especially the positioner used of armature punching.
Background technology
The armature punching is the significant components of motor, and during the flute profile punching out on the armature stamping, need the axis hole of armature stamping be positioned.Prior art generally adopts axis hole to add the keyway location; Its positioner is as shown in Figure 1; It is a stairstepping: the step edges that the bottom has is a pallet 1, and the column stage on top is a positioning disk 2, and pallet 1 is shaped to one with positioning disk 2; Chimeric being equipped with is decided to be strongly 4 on the periphery of positioning disk 2, on the disc face of positioning disk 2, has pin-and-hole 3.During punching out flute profile on armature stamping; The centre bore fit of armature stamping is installed on positioning disk 2; And be positioned on the pallet 1, the groove that armature stamping centre bore edge has is embedded in and is decided to be strong 4 location, pallet 1 is placed on the mould of flute profile punching out; And insert the jack on pin-and-hole 3 and the flute profile punching out mould with bearing pin, so realize Fig. 1 positioner and the location of treating the punching out armature stamping.Yet, often loading and unloading punching, positioning disk 2 and be decided to be strong 4 and be easy to wearing and tearing causes locating inaccuracy, moves dislocation during the punching punching out easily, influence the quality of punching out flute profile, needs the whole positioner of replacing.
The utility model content
The applicant is to above-mentioned existing punching positioner easy abrasion and cause locating shortcoming such as inaccuracy; The positioner of another kind of armature stamping is provided; When it can guarantee the punching machining accuracy; Can reduce the whole wearing and tearing of punching positioning disk again, also can make things convenient for the loading and unloading of punching, can improve working (machining) efficiency and reduce cost.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The positioner of armature stamping; Have the circular positioning disk of axis hole in the middle of comprising; First end of positioning core axle passes the axis hole of positioning disk, and the other end of positioning core axle is fixed in pedestal through connector, and the centre bore of pallet passes first end of positioning core axle and is connected with positioning disk by connector; The chimeric wear-resisting key that wear-resistant material is installed of the card upper edge circumference of positioning disk; The also chimeric positioning key that protrudes in the positioning disk card that is equipped with of the card upper edge circumference of positioning disk also has at least two dowel holes on the positioning disk.
Further technical scheme is:
Said wear-resisting key is a prismatoid, and a side central plane of said prismatoid is an arc surface, and the radian of said arc surface equates that with the radian of positioning disk periphery said arc surface engages with the periphery of positioning disk.The chimeric wear-resisting key that 6 wear-resistant materials are installed of the card upper edge circumference of positioning disk.
Said wear-resisting key tight fit is chimeric to be installed on the card of positioning disk, and the width of said wear-resisting key interior sidewall surface is greater than the width of outer side surface.
Said positioning key tight fit is chimeric to be installed on the card of positioning disk, and the width of said positioning key interior sidewall surface is greater than the width of outer side surface.
1, guaranteeing that armature stamping is had under the prerequisite of good location effect, increases the wear-resistant life-span of the utility model through a plurality of wear-resisting key that installs wear-resistant material at the positioning disk circumference additional.In the time of punching processing, stressed no longer concentrating on positioning disk and the positioning key, and be scattered in a plurality of wear-resisting keys, and often load and unload punching, positioning disk also not easy to wear, thus keep the accuracy of location.
2, positioning disk and pallet adopt and divide body structure, need to change even positioning disk weares and teares to some extent, also needn't change positioning core axle and pallet, thereby reduce production costs.
3, wear-resisting key is that a side central plane is the prismatoid of arc surface, also makes to add the easy to loading and unloading of punching in man-hour.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
Like Fig. 2, shown in Figure 3, in the middle of comprising, the utility model has the positioning disk 2 of axis hole 9, have pin shaft hole 3 and screw hole 5 on the positioning disk 2.One end of positioning core axle 7 passes the axis hole 9 of positioning disk 2, and the centre bore of pallet 1 passes an end of positioning core axle 7 and is connected with the screw hole 5 of positioning disk 2 by screw, and positioning core axle 7 is fixed in pedestal 10 through centre bolt.
The card upper edge circumference of positioning disk 2 evenly distributes and has 6 keyways, 6 wear-resisting keys 6 of chimeric installation in said 6 keyways, and wear-resisting key 6 is made by high-abrasive material.See Fig. 2, Fig. 4; Said wear-resisting key 6 is a prismatoid, and a side central plane of said prismatoid is an arc surface, and the radian of said arc surface equates with the radian of positioning disk 2 peripheries; Said arc surface engages with the periphery of positioning disk 2, and armature stamping 8 does not belong to the utility model among Fig. 4.See Fig. 2, also be provided with a positioning key 4 that protrudes in card on the card of positioning disk 2, also be provided with 2 symmetrical dowel holes 3 on the positioning disk 2.
See Fig. 2; Said wear-resisting key 6 and positioning key 4 are respectively on the chimeric card that is installed on positioning disk 2 of tight fit; Said wear-resisting key 6 and positioning key 4 are respectively interior sidewall surface two ends evagination; Be respectively the width of the width of interior sidewall surface, so make each wear-resisting key 6 and positioning key 4 can firmly be installed on positioning disk 2 greater than outer side surface.
See Fig. 3, when armature stamping 8 was installed, the centre bore of armature stamping 8 was inserted in the periphery of positioning disk 2, and at this moment, the centre bore of armature stamping 8 holds out against in the arc surface of the wear-resisting key 6 of each prismatoid, and armature stamping 8 does not belong to the utility model among Fig. 3.Fluting on the armature stamping 8 on the centre bore is inserted in the positioning key 4 on the positioning disk 2, so realizes the location to armature stamping 8.Pin shaft hole on two pin shaft holes, 3 aligned mandrels, the 7 upper end shoulders on the positioning disk 2 inserts the bearing pin location, so lock in place dish 2 in said pin shaft hole.When the processing punching, placement flute profile punching out mould can carry out the flute profile punching out below punching.
In the punching out process; Armature stamping is decomposed on each wear-resisting key 6 because of the friction of processing vibrations with positioning disk 2; Effectively reduce wearing and tearing,, thereby make the bulk life time of the utility model increase because wear-resisting key 6 processed by anti-abrasive material to positioning disk 2 and positioning key 4.And the arc surface structure that wear-resisting key 6 central planes of prismatoid have is easy to loading and unloading when also making armature stamping processing.
Positioning disk 2 adopts with pallet 1 and divides body structure, changes even positioning disk 2 weares and teares to some extent and needs, and also needn't change positioning core axle 7 and pallet 1, thereby reduce production costs.
