Description

Technical Field

[0001] This utility model relates to the technical field of rotor assembly equipment, and in particular to a rotor assembly tooling. Background Technology

[0002] An engine rotor generally consists of a rotor shaft, upper claw poles, lower claw poles, and a magnetic field winding and yoke located between the two claw poles. During production, according to the process sequence, the rotor shaft, claw poles, magnetic field windings, and yoke are generally assembled into the main body first. When assembling the main body, the claw poles, magnetic field windings, and other accessories are first put on the rotor shaft. With the help of the downward pressing force of the hydraulic equipment, the claw poles are pressed together to achieve the effect of fixing the claw poles and other components.

[0003] During assembly, the stability of the rotating shaft is related to the assembly accuracy of related parts. For ease of installation and removal, the rotor shaft is usually placed vertically in the positioning hole. This may cause some deviation from the rotor shaft clearance hole of the punch. When pressure is applied, the upper end of the rotor shaft is subjected to force, which can easily cause tilting or even deformation, affecting the quality of the rotor. Utility Model Content

[0004] The purpose of this invention is to provide a rotor assembly tooling to solve the problem.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rotor assembly tooling includes a base plate, cylinders, clamping plates, a centering assembly, a positioning ring, and a pressure head. The cylinders are symmetrically arranged on the base plate. The clamping plates are located on the power output ends of the cylinders, and the two clamping plates form a clamping structure. The centering assembly is located on the base plate, and the positioning ring is located on the upper surface of the centering assembly. The positioning ring has positioning holes adapted to the rotor's central shaft. The working end of the centering assembly clamps the rotor's central shaft, and the pressure head is located on the working end of a hydraulic device and faces the rotor.

[0006] A further technical solution is as follows: the centering assembly includes a turntable, a centering strip, a rack, a drive component, and a cover. The turntable is provided with a centering hole coaxial with the positioning hole, and the turntable is rotatably mounted on the base plate. The centering strip is slidably mounted on the base plate, and the outer end of the centering strip is slidably connected to the limiting groove on the turntable. The inner ends of the centering strip all face the centering hole. The rack meshes with the outer periphery of the turntable. The drive component is disposed on the base plate, and the power output end of the drive component is connected to the rack. The cover is disposed on the turntable, and the positioning ring is detachably mounted on the cover.

[0007] A further technical solution is that the limiting groove is an arc-shaped groove.

[0008] A further technical solution is that the cover is provided with a sliding groove, and the bottom of the clamping plate is slidably connected to the sliding groove.

[0009] A further technical solution is that the driving component is either a push rod motor or a cylinder.

[0010] A further technical solution is that the clamping plate is an arc-shaped plate, and the concave surface of the arc-shaped plate is provided with a wear-resistant layer.

[0022] This implementation example Figure 1 , Figure 2 , Figure 3 As shown, a rotor assembly tooling includes a base plate 1, a cylinder 2, a clamping plate 3, a centering assembly 4, a positioning ring 5, and a pressure head 6. The cylinders 2 are symmetrically arranged on the base plate 1, and the clamping plates 3 are arranged on the power output end of the cylinders 2, forming a clamping structure. The centering assembly 4 is arranged on the base plate 1, and the positioning ring 5 is arranged on the upper surface of the centering assembly 4.

The working end of the centering assembly 4 clamps the central shaft of the rotor 7, and the pressure head 6 is arranged on the working end of the hydraulic equipment and faces the rotor 7.

[0023] The working process of this utility model is as follows: the cylinder 2 retracts and the clamping plates 3 move away from each other, the pressure head 6 is raised, the centering component 4 is released, the operator places the rotor 7 vertically on the positioning ring 5, and then the centering component 4 clamps the central axis of the rotor 7 to complete the centering and clamping positioning. Then, the claw poles, magnetic field windings and magnetic yoke to be assembled are placed on the central axis in sequence. Then, the cylinder 2 pushes the clamping plate 3 to clamp the rotor 7. Finally, under the drive of the hydraulic equipment, the pressure head 6 presses down on the rotor 7 to quickly and stably complete the assembly of the rotor 7.

[0024] Preferably, the centering assembly 4 includes a turntable 8, a centering bar 9, a rack 10, a drive component 11, and a cover 12.

The drive component 11 is disposed on the base plate 1, and the power output end of the drive component 11 is connected to the rack 10. The cover 12 covers the turntable 8, and the positioning ring 5 is detachably mounted on the cover 12.

[0025] The drive unit 11 drives the turntable 8 to rotate through the tooth meshing structure. The turntable 8 carries the centering bar 9 to move towards or away from each other, thereby clamping or releasing the central shaft of the rotor 7 and achieving the effect of centering and positioning.

[0026] Preferably, the limiting groove 13 is an arc-shaped groove.

[0027] As the turntable 8 rotates, the end of the centering bar 9 changes position with the limit groove 13, and the positioning bar 9 moves passively.
