Description
Technical field
The utility model relates to a kind of riveting motor rear cover frock that is exclusively used in motor when assembling motor rear cover and electric machine casing riveting.
Background technology
In motor assembling process, having a procedure is motor rear cover and electric machine casing to be carried out to riveting fix.Motor rear cover and electric machine casing are carried out to riveting is fixing generally to be completed by riveting motor rear cover frock, but the riveting motor rear cover frock of prior art, complex structure volume is large, and motor rear cover is discontinuity when riveting, and the product appearance after riveting is affected.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of riveting that is exclusively used in motor when assembling motor rear cover and electric machine casing, simple in structure, the riveting motor rear cover frock of increasing work efficiency.
The utility model takes following technical scheme to complete:
Riveting motor rear cover frock, it is characterized in that: comprise cope match-plate pattern and lower bolster, the up and down setting of the relative lower bolster of cope match-plate pattern is led by vertical guide pillar, is provided with Compress Spring between bolster, the bottom surface of cope match-plate pattern is provided with pressure head, and the end face of lower bolster is provided with riveting fixture, riveting fixture comprises clamp head, sleeve base and riveting pawl, sleeve base is fixed on lower bolster, clamp head is in the up and down setting of endoporus of sleeve base, the end face of clamp head is provided with the location of counterbore for motor rear cover, the bottom of clamp head is provided with return spring, the external cylindrical surface of clamp head is provided with many places tangential slot, described riveting pawl is located in tangential slot, the nearly counterbore of upper jaw head rest of riveting pawl arranges on one side, lower jaw arm and the clamp head of riveting pawl are articulated and connected, pawl arm inner side is provided with ejector spring, in clamp head during in upper limit position, under the effect that ejects of ejector spring, pawl arm outside exposes to the external cylindrical surface of clamp head.
Adopt the riveting motor rear cover frock of technique scheme, volume simple in structure is little, motor rear cover is stressed even when riveting, product appearance after riveting is attractive in appearance, operation principle is: motor rear cover is put in counterbore and is located, then put electric machine casing, then punch press unit head promotion cope match-plate pattern and pressure head move down, pressure head props up electric machine casing pushing motor housing, motor rear cover moves down together with clamp head, in the folding process of clamp head, the endoporus driving pawl arm of sleeve base inwardly swings, so pawl head starts the flange of motor rear cover to carry out riveting, until clamp head arrives during lower position, riveting end-of-job, pressure head return subsequently, clamp head also return under return spring effect, then take out workpiece, circulation according to this, operating efficiency is high.
As preferably, described pressure head is nylon material.Can prevent the scratch of product casing.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structure chart of the present utility model.
The specific embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings more each details and the operation principle thereof of embodiment below.
As shown in the figure, riveting motor rear cover frock of the present utility model, comprise cope match-plate pattern 4 and lower bolster 1, the up and down setting of cope match-plate pattern 4 relative lower bolster 1 is led by vertical guide pillar 3, between bolster, be provided with Compress Spring 2, the bottom surface of cope match-plate pattern 4 is provided with pressure head 5, and pressure head is nylon material, and the end face of lower bolster 1 is provided with riveting fixture, riveting fixture comprises clamp head 8, sleeve base 7 and riveting pawl 9, sleeve base 7 is fixed on lower bolster 1, clamp head 8 is in the up and down setting of endoporus of sleeve base 7, the end face of clamp head 8 is provided with the location of counterbore 10 for motor rear cover 101, the bottom of clamp head 8 is provided with return spring 6, the external cylindrical surface of clamp head 8 is provided with the magnitude setting of many places tangential slot 12(tangential slot and according to product riveting, counts and determine), described riveting pawl 9 is located in tangential slot 12, the nearly counterbore 10 of upper jaw head rest of riveting pawl 9 arranges on one side, lower jaw arm and the clamp head 8 of riveting pawl 9 are articulated and connected, pawl arm inner side is provided with ejector spring 11, in clamp head 8 during in upper limit position (position shown in Fig. 1), under the effect that ejects of ejector spring 11, pawl arm outside exposes to the external cylindrical surface of clamp head 8.
Riveting motor rear cover frock of the present utility model is work like this: motor rear cover 101 is put into the interior location of counterbore 10, then put electric machine casing 102, then punch press unit head promotion cope match-plate pattern 4 and pressure head 5 move down, pressure head 5 props up electric machine casing 102 pushing motor housings 102, motor rear cover 101 moves down together with clamp head 8, in the folding process of clamp head 8, the endoporus driving pawl arm of sleeve base 7 inwardly swings, so pawl head starts the flange of motor rear cover 101 to carry out riveting, until clamp head arrives during lower position, riveting end-of-job, pressure head 5 returns subsequently, clamp head 8 also return under return spring 6 effect, then take out workpiece, circulation according to this, operating efficiency is high.
