Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Fig. 1 shows an outer rotor motor casing to be punched, and punching holes 14 are respectively located at two ends of the casing 1. The machine shell 1 is divided into an inner ring 11 and an outer ring 12, wherein a mounting hole on the inner ring 11 is used for assembling a motor end cover, and a mounting hole on the outer ring 12 is used for assembling external equipment.

The punching fixing device for the outer rotor motor shown in fig. 2-4 comprises a base 2 and a fixing seat 3, wherein the fixing seat 3 is arranged above the base 2. A longitudinal supporting hole 21 is formed in the fixed seat 3, and the diameter of the supporting hole 21 is equal to the outer diameter of the inner ring 11 of the shell to be punched; the supporting hole 21 is used for fixing the inner ring 11 of the casing 1 to be punched, the inner ring 11 of the casing 1 penetrates through the supporting hole 21, the outer ring 12 of the casing 1 is isolated at the other end of the fixed seat 3, and the parts to be punched on the mechanism are respectively arranged at two sides of the fixed seat 3;

fixing base 3 still is provided with fastener, fastener is including setting up in the first cylinder 32 of fixing base 3 both sides, the piston shaft fixedly connected with splint 33 of first cylinder 32, and two splint 33 are close to each other under the drive of first cylinder 32 in order to realize the fastening to casing 1. Specifically, in this embodiment, a connection seat 34 extends from two sides of one end of the fixing seat 3, the first cylinder 32 is fixed at an outer side of the connection seat 34, and a piston shaft of the first cylinder 32 passes through the connection seat 34. The two clamping plates 33 move relatively to apply a radial pressing force to the outer ring 12 of the casing 1 outside the fixing seat 3, so that the casing 1 is stabilized in the supporting hole 21. Further, the surface of the motor housing involved in the present embodiment is in a smooth arc shape, and the clamping plate 33 is also in an arc shape to be adapted to the surface of the housing 1, and provide a multi-directional fastening force to the housing 1 when the clamping plate 33 moves.

The utility model discloses a fixing base 3 that has the support hole 21 lays casing 1 main part, forms axial positioning to casing 1, makes the both ends that casing 1 waited to punch arrange in the both ends of fixing base 3 separately, and rethread first cylinder 32 promotes the splint 33 of both sides, and the radial fastening to the motor can be realized to both sides splint 33 mutual approaching; at this moment, the perforating machine at the two ends of the fixing seat 3 is started, the perforating machine can simultaneously perforate the two ends of the casing 1, the perforating machine is convenient and fast, and the perforating position is stable and accurate.
