Specific embodiment

For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.

In conjunction with Fig. 1, indicate that a kind of field frame assembly, hatched parts are stator casing side wall, internal arrangement has magnetic shoe.? On axial direction, multi-disc magnetic shoe is placed on same stator casing, circumferential direction also has the arrangement of multi-disc magnetic shoe.This field frame assembly Since magnetic shoe number is more, quality is difficult to ensure when assembly, and quality and efficiency when assembly is caused to be difficult to be effectively improved simultaneously.This For this problem, provided assembly device can achieve the purpose that quick assembling to utility model, and can guarantee higher production Quality.

Embodiment 1

In conjunction with Fig. 2, Fig. 3, a kind of Automated assembly device of starter stator assembly of the present embodiment, including pressure mechanism And assemble mechanism, pressure mechanism include rack 61 and the cylinder body 62 that is vertically installed in rack 61, rack 61 primarily serves support Effect, bottom is workbench, for placing processed component.There is the crossbeam of stretching in 61 upper end of rack, is connected on crossbeam Cylinder body 62, for example, by using cylinder, the cylinder is vertically-mounted, and piston rod is downward, then is capable of providing downward pressure.

Assemble mechanism is placed on workbench, positioned at the lower section of cylinder body 62, then piston rod can be utilized to assembly machine Structure provides external pressure.

Assemble mechanism includes pedestal 1, swelling pressure column 3 and compression bar 5 in the present embodiment, and the swelling pressure column 3 is by 4 pieces of swelling pressure blocks 31 Circumferential split composition, and tied up by the way that elastic element 4 is circumferential.

Swelling pressure column 3, which can be regarded as, is divided into the identical swelling pressure block of 4 shapes by axially cutting mode by a cylinder 31, the inner wall circular arc that the outer wall arc diameter of swelling pressure block 31 is less than magnetic shoe to be assembled is direct, come into full contact with the two can. After 31 distending of swelling pressure block, also want can self-return, therefore swelling pressure block 31 is banded in one by the way that elastic element 4 is circumferential It rises.

In conjunction with Fig. 4, the outer wall of swelling pressure block 31 is provided with the groove 32 of horizontal direction, and elastic element 4 can be rubber rubber band, If necessary to provide biggish screen resilience, then spring can be used, elastic element 4 is mounted in groove 32.If axial direction side Only have to magnetic shoe a piece of, then a groove 32 can be set, or a groove 32 is respectively set in upper and lower side, provides more preferable Rebound and distending effect.

The quantity of swelling pressure block 31 is mainly to be determined according to the arrangement of magnetic shoe in electronic assembly to be processed.Such as same One circumferential direction has 4 blocks of magnetic shoes, then 4 swelling pressure blocks 31 are arranged, and if there is 3 magnetic shoes, then only needs 3 swelling pressure blocks 31, tool Body can be set according to the demand of the field frame assembly of actual processing.

Guide post 15 is installed on pedestal 1 in the present embodiment, which can be is installed by thread fiting mode, It is also possible to so that the two is integrally fixed by being welded to connect.Sliding slot 53 is offered in compression bar 5, the sliding slot 53 and guide post 15 Coaxially, the purpose of guide post 15 is to be oriented to, and compression bar 5 is enable to slide up and down along guide post 15.
