Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotor magnetization, in particular to a magnetization pin angle positioning mechanism. Background Art
[0002] In recent years, the domestic new energy vehicle industry has developed well. Automobile rotors need to be strongly magnetized. The traditional magnetization technology is to magnetize the magnetic steel on the rotor piece by piece before assembly. When magnetizing, the traditional magnetization equipment needs to rotate the rotor through a rotating mechanism to find the magnetization angle that matches the rotor on the tooling and the magnetization coil. However, the common rotating mechanism cannot effectively stop, which may cause the rotor to miss the optimal magnetization angle. Therefore, a magnetization pin angle positioning mechanism is proposed. Utility Model Content
[0003] The utility model aims to provide a magnetizing pin-finding angle positioning mechanism to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetized pin angle positioning mechanism, comprising a base plate, a fixing part is fixedly connected to the surface of the base plate, a reinforcing plate is fixedly connected between the side wall of the fixing part and the surface of the base plate, a sliding groove and a movable cavity are provided on the surface of the fixing part, a tooth plate and a limiting protrusion are slidably connected to the inner side wall of the sliding groove, and a transmission mechanism for moving the tooth plate is provided on the inner side wall of the movable cavity.
[0005] As a preferred solution, the transmission mechanism includes a rotating shaft, a fixed seat, a cylinder, a hinge, a connecting rod and a gear. The inner side wall of the movable cavity is rotatably connected with a gear, and the gear and the toothed plate are meshed with each other.
[0006] As a preferred solution, the inner side wall of the movable cavity is rotatably connected to a rotating shaft, the surface of the rotating shaft is fixedly connected to a fixing seat, the surface of the fixing seat is fixedly connected to a cylinder, and the movable end of the cylinder is fixedly connected to a hinge.
[0007] As a preferred solution, a connecting rod is hinged between the hinge and the gear.
[0008] As a preferred solution, pin grooves are provided on the surfaces of the tooth plate and the limiting protrusion, and the tooth plate and the limiting protrusion are fixedly connected via the pin grooves and an external pin shaft.
[0009] Technical effects and advantages of the utility model:
[0010] 1. When the cylinder is running, the power output end of the cylinder rotates to drive the hinge to move. The movement of the hinge drives the gear to rotate under the action of the connecting rod. The rotation of the gear drives the tooth plate to move, so that the tooth plate moves in a straight line. The movement of the tooth plate drives the limit convex block to move. The limit convex block moves and is stuck in the inter-tooth groove of the rotor, which effectively stops the rotor, prevents the rotor from missing the optimal magnetization angle, and ensures the magnetization efficiency.
[0011] 2. The rotor is stopped by the limit block, and the probability of damage is high after long-term use. When the limit block is damaged, the limit block can be pushed out by the tooth plate, and then replaced by the pin groove and the external pin shaft to ensure the normal operation of the entire mechanism and facilitate the installation and removal of the limit block.
