Description

Technical Field

[0001] The utility model belongs to the related technical field of accessories for motor processing, and particularly relates to a stator constant-pressure quick locking mechanism. Background Technique

[0002] During the processing of a motor, winding and wire insertion are required. The wire insertion method is to insert a wire winding into the wire grooves of the stator. Therefore, there is an automatic wire insertion machine for motor stators. The current automatic wire insertion machine for motor stators includes a stator positioning mechanism, such as Figure 1 、 Figure 2 shown. The stator positioning mechanism generally includes a fixed seat 1, a constant-pressure adjusting plate 2, and two guide rods 3. The two guide rods 3 are vertically fixed on the fixed seat 1. The constant-pressure adjusting plate 2 is slidably connected between the two guide rods 3. A stator groove 4 for fixing one end face of the stator is provided on the fixed seat 1. The lower surface of the constant-pressure adjusting plate 2 is used for fixing and limiting the other end face of the stator 5. However, since only most of one end face of the stator 5 is pressed and limited by the lower surface of the constant-pressure adjusting plate 2, when installing the stator positioning mechanism, it needs to be Figure 1 inverted and installed, that is, ensuring that the fixed seat 1 is located above the constant-pressure adjusting plate 2. Therefore, when inserting wires, the wire group passes through the holes of the stator groove 4 and then enters the wire grooves of the stator 5. Therefore, as Figure 2 shown, since a part of the edge of one end face of the stator 5 is still exposed outside, such a structure causes uneven stress on the stator during wire insertion, and it is easy to have the problem of tipping over, ultimately affecting the wire insertion effect. Therefore, improvement is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a stator constant-pressure quick locking mechanism, which solves the problem that when the existing constant-pressure adjusting plate presses one end face, a part of the edge of one end face of the stator is still exposed outside. Such a structure causes uneven stress on the stator during wire insertion, and it is easy to have the problem of tipping over, ultimately affecting the wire insertion effect.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model relates to a stator constant-pressure quick locking mechanism, which comprises a fixed seat, a constant-pressure adjusting plate and two guide rods. A stator groove for installing a stator is arranged on the fixed seat. The two guide rods are fixed on the left and right sides of the fixed seat relative to the stator groove. The constant-pressure adjusting plate is slidably connected between the two guide rods. The constant-pressure adjusting plate is arranged in parallel with the fixed seat, and a U-shaped notch aligned with the stator groove is arranged on the constant-pressure adjusting plate. A locking assembly for locking the stator is arranged on the surface of the constant-pressure adjusting plate facing the fixed seat. The locking assembly comprises an arc-shaped limiting block and two C-shaped locking rings. The arc-shaped limiting block is located on the side of the U-shaped notch. One of the C-shaped locking rings is arranged on each side of the arc-shaped limiting block. The two C-shaped locking rings are arranged in a mirror image. The center of each C-shaped locking ring is hinged on the constant-pressure adjusting plate through a hinge shaft. A C-shaped step is arranged on the lower surface of each C-shaped locking ring. An arc-shaped step is arranged on the arc-shaped limiting block. The arc-shaped step and the two C-shaped steps cooperate to form a limiting circular groove for fixing the stator.

[0006] Preferably, an arc-shaped notch surface is arranged on each side of the arc-shaped limiting block.

[0007] Preferably, arc-shaped surfaces are arranged on the inner and outer sides of both ends of the C-shaped locking ring.

[0008] Preferably, for the convenience of disassembly, the arc-shaped limiting block is threadedly connected with the constant-pressure adjusting plate through two locking screws.

[0009] Preferably, for the convenience of adjusting the height and realizing the positioning and locking of the constant-pressure adjusting plate, two bearings located on the left and right sides of the U-shaped notch are fixed on the constant-pressure adjusting plate. The guide rod penetrates through the inner ring of the bearing. A locking rod penetrates through the constant-pressure adjusting plate. A locking knob for threadedly connecting the side surface of the locking rod is arranged on the side surface of the constant-pressure adjusting plate.

[0010] Preferably, for the convenience of disassembly, the bottom of the locking rod penetrates through the fixed seat and is threadedly connected with a fixing nut. An operating handle is arranged at the bottom of the locking rod.

[0011] Preferably, the fixed seat is provided with a sliding guide groove. The side of the sliding guide groove is a notch. A stator positioning plate is slidably connected on the sliding guide groove. The stator groove is located on the stator positioning plate.

[0012] The utility model has the following beneficial effects: The setting of this structure can press the two end faces of the stator in all directions, and the force is uniform. The two end faces of the stator are entirely wrapped. Compared with the existing state where one end face of the stator is partially exposed, the pressing of the stator by this structure is more comprehensive and stable, and the problem of "when inserting wires, the stator is stressed unevenly and is prone to tipping over" will not occur.

Detailed Description of the Preferred Embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] Please refer to Figure 2-10 As shown, a stator constant-voltage quick locking mechanism disclosed in this embodiment includes a fixed seat 1, a constant-voltage adjusting plate 2, and two guide rods 3. A stator slot 4 for installing a stator 5 is provided on the fixed seat 1. The two guide rods 3 are fixed on the left and right sides of the fixed seat 1 relative to the stator slot 4. The constant-voltage adjusting plate 2 is slidably connected between the two guide rods 3. The constant-voltage adjusting plate 2 is arranged parallel to the fixed seat 1, and a U-shaped notch 201 aligned with the stator slot 4 is provided on the constant-voltage adjusting plate 2. A locking assembly for locking the stator 5 is provided on the surface of the constant-voltage adjusting plate 2 facing the fixed seat 1. The locking assembly includes an arc-shaped limiting block 6 and two C-shaped locking rings 7. The arc-shaped limiting block 6 is located on the side of the U-shaped notch 201. A C-shaped locking ring 7 is provided on each side of the arc-shaped limiting block 6. The two C-shaped locking rings 7 are arranged in a mirror image, and the center of each C-shaped locking ring 7 is hinged to the constant-voltage adjusting plate 2 through a hinge shaft 8. A C-shaped step 701 is provided on the lower surface of the C-shaped locking ring 7. An arc-shaped step 601 is provided on the arc-shaped limiting block 6. The arc-shaped step 601 and the two C-shaped steps 701 cooperate to form a limiting circular groove 9 for fixing the stator 5.

[0028] Preferably, a sliding guide groove 101 is provided on the fixed seat 1. The side of the sliding guide groove 101 is a notch. A stator positioning plate 102 is slidably connected to the sliding guide groove 101. The stator slot 4 is located on the stator positioning plate 102. When it is necessary to remove the stator 5 later, only need to manually pull the stator positioning plate 102, and the stator positioning plate 102 can drive the stator 5 to quickly slide out of the sliding guide groove 101, which is convenient for later disassembly of the stator 5. And when the stator 5 slides out, since the two C-shaped locking rings 7 are hinged to the constant-voltage adjusting plate 2, the two C-shaped locking rings 7 are opened as the stator 5 slides out, which further facilitates the quick removal of the stator 5.

[0029] Preferably, an arc-shaped notch surface 602 is provided on each side of the arc-shaped limiting block 6, and an arc-shaped surface 702 is provided on the inner and outer sides of both ends of the C-shaped lock ring 7. In this embodiment, by providing the arc-shaped notch surfaces 602 on both sides of the arc-shaped limiting block 6, when the C-shaped lock ring 7 pushes the stator 5 during manual feeding, it can play a role in avoiding interference, preventing the problem that the stator 5 cannot be limited finally. At the same time, the inner and outer arc-shaped surfaces 702 at one end of the C-shaped lock ring 7 close to the arc-shaped limiting block 6 also play a role in avoiding interference. For the inner and outer arc-shaped surfaces 702 at one end of the C-shaped lock ring 7 far from the arc-shaped limiting block 6, the inner arc-shaped surface 702 is convenient for manual taking of the stator 5 later, avoiding touching the surface of the stator 5 and damaging it. At the same time, because it is an arc surface, it is also convenient for the stator to be taken out. The outer arc-shaped surface 702 is convenient for manual pushing of the stator 5 between the two C-shaped lock rings 7. Because it is an arc surface, it plays a guiding role and is convenient for rapid feeding.

[0030] Preferably, for convenient disassembly, the arc-shaped limiting block 6 is threadedly connected to the constant pressure adjusting plate 2 through two locking screws 10. In this embodiment, the arc-shaped limiting block 6 is fixed on the constant pressure adjusting plate 2 through the locking screws 10, which is convenient for later disassembly. Moreover, using two locking screws 10 can ensure stability and connection strength.

[0031] Preferably, in order to conveniently adjust the height and realize positioning and locking of the constant pressure adjusting plate 2, two bearings 11 are fixed on the constant pressure adjusting plate 2 on the left and right sides of the U-shaped notch 201. The guide rod 3 passes through the inner ring of the bearing 11. A locking rod 12 penetrates through the constant pressure adjusting plate 2, and a locking knob 13 is threadedly connected to the side of the locking rod 12 on the side of the constant pressure adjusting plate 2; by rotating the locking knob 13 in this structure, when the screw head on the locking knob 13 does not abut against the locking rod 12, the height of the constant pressure adjusting plate 2 can be quickly adjusted under the cooperation of the bearing 11. Compared with the existing adjustment structure, the adjustment method of this structure is simpler and more convenient, enabling free adjustment of the height of the constant pressure adjusting plate 2; at the same time, even if the locking knob 13 is loosened, since the inner ring of the bearing 11 fits with the outer ring of the guide rod 3, the entire constant pressure adjusting plate 2 will not fall freely and finally affect the adjustment effect.

[0032] At the same time, for convenient disassembly, the bottom of the locking rod 12 passes through the fixing seat 1 and is threadedly connected to a fixing nut 14, and an operation handle 15 is provided at the bottom of the locking rod 12. The operation handle 15 is provided for convenient later operation.

[0033] In this embodiment, by first fixing an arc-shaped limiting block 6 at the bottom of the constant-pressure adjusting plate 2 relative to the side of the U-shaped notch 201, then arranging two C-shaped lock finger rings 7 which are mirror-symmetrically arranged on both sides of the arc-shaped limiting block 6, and arranging a C-shaped step 701 on the C-shaped lock finger ring 7 and an arc-shaped step 601 on the arc-shaped limiting block 6. In the initial state, the two C-shaped lock finger rings 7 are opened outwards, and the openings at the ends where the two C-shaped lock finger rings 7 are close to each other become larger (as Figure 7 shown, rotate and open in the direction of the arrow), which is convenient for the stator 5 to enter from the openings where the two C-shaped lock finger rings 7 are opened. As the stator 5 enters, the ends of the two C-shaped lock finger rings 7 close to the arc-shaped limiting block 6 rotate around the point of the hinge shaft 8 with the push of the stator 5, in order to Figure 7 rotate in the opposite direction of the above arrow. Finally, when the stator 5 is stuck into the arc-shaped step 601 of the arc-shaped limiting block 6, the C-shaped lock finger rings 7 form the state as Figure 7 shown. At this time, the arc-shaped step 601 and the C-shaped step 701 form a circular limiting circular groove 9 for locking one end face of the stator 5. At the same time, the other end face of the stator 5 is locked by the stator groove 4, and finally the pressing and limiting effect on the stator is realized. And through the setting of this structure, the two end faces of the stator can be pressed in all directions, and the force is uniform. The two end faces of the stator are completely wrapped. Compared with the existing state where part of one end face of the stator is exposed outside, the pressing of the stator by this structure is more comprehensive and stable, and the problem of "when inserting the wire, the stator is stressed unevenly and is prone to tipping over" will not occur.

[0034] The above is only the preferred embodiment of the present invention, and it does not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, and any equivalent replacement of some technical features, any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
