Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle drive motor technology, specifically to an axial force balancing rotor support device. Background Technology

[0002] The new energy vehicle industry is developing rapidly, and the industrial chain is gradually extending towards refinement. The core power component in new energy vehicles is the new energy motor. As the industrial chain continues to extend and develop, the requirements for the quality and performance of new energy motors are gradually increasing. New energy motors are no longer satisfied with simply undergoing whole-machine testing. More and more companies are choosing to purchase finished rotors from downstream industrial chain companies for assembly in order to achieve the goal of quickly producing motor products.

[0003] In the prior art, Chinese utility model application number CN202321735470.3 describes a rotor shaft structure for a new energy vehicle motor. The rotor shaft has a rotor silicon steel sheet sleeved on its outer side, an internal spline on the inner side of the rear end of the rotor shaft, and a bearing sleeved on the outer side of the front end of the rotor shaft. The rotor shaft includes a shaft body, with a bearing connection at the front end of the shaft body. The outer diameter of the bearing connection is smaller than the outer diameter of the shaft body. The bearing is sleeved on the rear of the bearing connection. The front end of the bearing connection is sealed by an integrally formed cover plate. The cover plate protrudes forward and has a discharge tip, which is set along the central axis of the rotor shaft and is conical in shape. This utility model releases the shaft voltage by setting a discharge tip on the rotor shaft. The breakdown current is conducted through the housing to the vehicle frame and ground, preventing the bearing from being corroded by the current. In the case of a vehicle with reverse main drive transmission and auxiliary drive following rotation, it solves the problem of induced electromotive force generated by electromagnetic resistance in the auxiliary drive motor, improves the transmission efficiency of the main drive motor, and increases the energy utilization rate of the battery pack.

[0004] Existing technology requires the rotor shaft to be inspected before installation. During inspection, the rotor shaft is placed on a platform. However, the rotor needs to be touched during the inspection process, which can cause the rotor to shake. This may cause the rotor shaft to rub or collide with the platform, thereby damaging the rotor shaft and affecting its service life when it is installed on the automotive motor. Therefore, we need to propose an axial force balancing rotor support device. Utility Model Content

[0025] The support component 8 includes a column 81, with a support ring 86 integrally formed at the upper end of the column 81, a limit block 87 fixedly connected to one side of the column 81, and a retaining frame 88 provided at the upper outer side of the support ring 86.

[0026] The limiting component 9 includes a closed ring 91 rotatably disposed at one end of the support ring 86. A locking bolt 92 is threadedly connected to the outer side of the closed ring 91. A pressure plate 93 is rotatably disposed at one end of the locking bolt 92. A buckle 96 is rotatably disposed at one end of the closed ring 91. A buckle 961 that engages with the buckle frame 88 is disposed at one end of the buckle 96.

[0027] Two sets of telescopic rods 94 are fixedly connected to the inner side of the closed ring 91. One end of each set of telescopic rods 94 is fixedly connected to the upper surface of the pressure plate 93. A second buffer pad 95 is bonded to the lower surface of the pressure plate 93. Pull rings 962 are rotatably provided at both ends of the locking block 961. The pull rings 962 can be used to quickly and easily disengage the locking block 961 from the locking frame 88, thereby improving the efficiency of opening the closed ring 91. At the same time, the telescopic rods 94 improve the stability of the pressure plate 93 when it is raised and lowered, and improve the stability of the rotor end positioning.

[0028] The inner side of the support ring 86 is bonded with a first buffer pad 89. The length of the pressure plate 93 is less than the length of the support ring 86. Both the support ring 86 and the closing ring 91 are C-shaped. The first buffer pad 89 is used to reduce the damage to the rotor caused by rigid clamping.

The guide rod 5 is slidably disposed in the first sliding hole 83. The upper surface of the base 1 is equipped with a guide rail 6 that is slidably disposed in the second sliding hole 84. The column 81 is slidable along the guide rod 5 and the guide rail 6 by using the first sliding hole 83 and the second sliding hole 84, thereby improving the stability of the column 81 movement.

[0030] A side hole 82 is provided on the side of the column 81 adjacent to the limiting block 87. Two sets of through holes 85 connected to the side hole 82 are provided on the lower surface of the column 81. A positioning component 10 is provided in the side hole 82.

The upper end of the adjusting bolt 41 is fixedly connected to a rotating wheel 42, and the lower end of the adjusting bolt 41 is fixedly connected to a piston plate 43. The lower surface of the base 1 has a piston hole 11 for the piston plate 43 to slide. The position of the piston plate 43 can be easily adjusted by adjusting the adjusting bolt 41, thereby reducing the pressure in the piston hole 11 so that the base 1 can be adsorbed onto the platform, thereby improving the stability of the base 1.

[0033] An anti-slip pad 2 is bonded to the lower surface of the base 1. The lower surface of the anti-slip pad 2 has an air hole that communicates with the piston hole 11. The anti-slip pad 2 improves the sealing between the base 1 and the platform, thereby improving the stability of the base 1.

[0034] In use, place the base 1 on the platform and rotate the adjusting bolt 41 to move the piston plate 43 from the lowest point to the highest point, thereby reducing the pressure in the piston hole 11 so that the base 1 can be attached to the platform, improving the stability of the base 1. By lifting a set of positioning components 10 upwards, the position of the column 81 can be adjusted. Place one end of the rotor to be inspected on the support ring 86 and abut against the limiting baffle. Repeat the operation of the positioning components 10 on the other set of columns 81 so that the other end of the rotor abuts against one side of the limiting block 87. Flip the limiting component 9 and lock the block 961 into the frame 88, thereby improving the stability of the closed ring 91 after it is closed. Rotate the locking bolt 92 to adjust the position of the pressure plate 93 so that the second buffer pad 95 abuts against the outside of the rotor, thereby improving the stability of the rotor positioning, facilitating the positioning of rotors of different specifications, avoiding shaking during rotor maintenance, and thus improving the efficiency of rotor maintenance.
