Description

[0002] With the development of transportation and technology, new energy vehicles have come into being. New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] The production process of automotive-grade flat wire motor stators and rotors is complicated, including at least the steps of rotor processing, stator processing, flat wire copper wire processing and assembly. The stator processing includes stator core threading, core detection, paper insertion, wire forming, wire insertion, flaring, twisting, cutting, welding and detection. The stator core needs to be fixed during production and processing so that it can be precisely processed to meet the structural requirements of the motor stator. The existing stator core fixing device is mainly clamped and fixed by two left and right clamps. The two arc-shaped clamps are relatively independent, and the distance they move each time cannot be guaranteed, resulting in the core axis position after each clamping being too arbitrary, which increases the difficulty of calibration of subsequent processing technology. Therefore, it needs to be improved. Utility Model Content

[0027] Among them, due to the setting of the clamping roller 8, the stator core can be clamped with the cooperation of the two clamping arc blocks 6, and can also be rotated after clamping the core. At this time, the reverse rotation of the core axis will not affect its clamping and fixing, which greatly facilitates the processing operations after clamping and fixing.

[0028] like Figure 1 As shown, the adjustment component includes a linkage ring 12 rotatably sleeved on the outside of the operating table 1, and the top of the linkage ring 12 is meshedly connected with two left and right linkage gears 14, and the outer surface of the linkage gear 14 is connected with a handle 16; due to the setting of the handle 16, it is convenient for the staff to rotate the linkage gear 14, and then with the cooperation of the linkage ring 12, it can be ensured that the two linkage gears 14 can rotate synchronously.

[0029] like Figure 1 As shown, a pulley 13 is arranged above the linkage gear 14 , a transmission belt 15 is transmission-connected between the linkage gear 14 and the pulley 13 , the linkage gear 14 is movably connected to the support frame 2 , and the pulley 13 is fixedly connected to the connecting sleeve 3 .

[0030] like Figure 3 As shown, the outer surface of the connecting sleeve 3 is fixedly connected to one end of the supporting frame 2 with a plurality of evenly distributed positioning rings 10, and the internal movable sleeve of the positioning ring 10 is connected to the limiting rod 11, both ends of the limiting rod 11 pass through the positioning ring 10, and one end of the limiting rod 11 is fixedly connected to the supporting frame 2; due to the setting of the positioning ring 10 and the limiting rod 11, the cooperation between the two can ensure that the adjusting rod 4 can move smoothly horizontally to the left and right, and can avoid the situation that the adjusting rod 4 rotates accidentally, thereby ensuring that the adjusting rod 4 can move left and right when the connecting sleeve 3 rotates.

[0031] like Figure 1 and Figure 3 As shown, a second bearing 9 is fixedly sleeved on the outer surface of the connecting sleeve 3 , and the second bearing 9 is sleeved inside the supporting frame 2 .

[0032] like Figure 4As shown, the connector 5 includes a connecting ring 51 installed between the connecting sleeve 3 and the clamping arc block 6, one end of the connecting ring 51 is fixedly connected to the clamping arc block 6, and the other end of the connecting ring 51 is in contact with the connecting sleeve 3;

[0034] Among them, due to the setting of the connecting head 5, under the elastic force of the spring spring 53, it can be ensured that when there is no external force, the clamping arc block 6 can always maintain a horizontal state, and after being acted upon by an external force, the clamping arc block 6 can rotate around the axis of the rotating shaft 52, so that the stator core clamped by the two clamping arc blocks 6 can be turned upside down;

[0035] A connecting shaft 54 ​​is movably sleeved inside the connecting ring 51 and fixedly connected to the rotating shaft 52 . A first bearing 55 is sleeved between the connecting ring 51 and the connecting shaft 54 ​​. The outer diameter of the rotating shaft 52 is larger than that of the first bearing 55 .

[0036] The working principle and use process of this utility model:

[0037] Place the stator core between the two clamping arc blocks 6, and then use any handle 16 to rotate a corresponding linkage gear 14, and then make the other linkage gear 14 rotate synchronously with the cooperation of the linkage ring 12, and then make the two adjustment rods 4 rotate at the same time with the cooperation of the transmission belt 15 and the pulley 13. Due to the rotation of the adjustment rod 4, the connection sleeve 3 can move relative to each other under the restriction of the positioning ring 10 and the limit rod 11, so that the two connection sleeves 3 can move toward each other, and then the two clamping arc blocks 6 and the plurality of clamping rollers 8 at the front end thereof can move toward each other through the connector 5, thereby clamping the stator core;

[0038] Rotate the stator core, and with the cooperation of the clamping roller 8, the stator core can be rotated during the clamping of the left and right clamping arc blocks 6;

[0039] To flip the stator core, the two clamping arc blocks 6 and the clamping roller 8 can be driven to rotate around the axis of the rotating shaft 52 while the left and right clamping arc blocks 6 and the clamping roller 8 are clamped. Under the restriction of the adjusting rod 4, the connecting shaft 54 ​​and the rotating shaft 52, the clamping arc block 6 drives the connecting ring 51 to rotate. The rotation of the connecting ring 51 relative to the rotating shaft 52 can twist the clockwork spring 53 to enhance its elastic recovery performance. Thereby, the purpose of flipping the stator core is achieved and the core can be automatically reset to the vertical axis state after being released.
