Detailed implementation manners

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0048] Please refer to Figures 1-12, a motor rotor assembly tool provided in this embodiment for motor production includes an assembly frame 1. A support block 11 is arranged in the assembly frame 1, and a through groove 12 is formed on the support block 11. The assembly frame 1, the support block 11, and the through groove 12 are all existing assembly parts. And the through groove 12 on the support block 11 is located directly below the rotating shaft. A plugging component is arranged in the support block 11 for plugging the through groove 12. The through groove 12 is plugged by moving the plugging component, so as to provide a certain supporting force for the bottom of the rotating shaft during assembly; A clamping component one is vertically slidably connected in the assembly frame 1, which is used to clamp the iron core. An expanding grinding block device 13 for processing the inside of the iron core is also arranged in the assembly frame 1. The expanding grinding block device 13 is an existing expander, and grinding blocks are arranged on its outside, which can polish the inner wall of the iron core. The expanding grinding block device 13 expands to shape the iron core, improve the smoothness inside the iron core, and reduce damage to the rotating shaft; A clamping component two for clamping the rotating shaft is arranged in the assembly frame 1; It also includes a stamping component and a material taking component, both of which are arranged in the assembly frame 1; During operation, the expanding grinding block device 13 moves into the iron core in the clamping component one for processing. After completion, the clamping component one moves upward, and is driven by a guiding component to drive the iron core to rotate. The guiding component can drive the clamping component one to drive the iron core to rotate from parallel to the operation surface to perpendicular to the operation surface, and its rotation angle is 90°. After rotation, it is convenient for waste chips to be discharged and also convenient for the installation of the rotating shaft; When the stamping component moves downward, it has the following three working positions:

[0049] The first working position: The stamping component moves downward to drive the clamping component two to move and rotate, so as to move the rotating shaft to directly above the iron core, and drive the support block 11 to move horizontally to directly below the clamping component one through a linkage component one;

[0050] The second working position: The stamping component drives the clamping component two to continue to move downward, inserts the rotating shaft into the iron core, and drives the support block 11 to move upward to abut against the bottom of the iron core to support it through a linkage component two;

[0051] The third working position: During the downward movement stroke of the stamping component, after the material taking component is triggered to move and clamp the iron core again through a triggering mechanism, the plugging component is triggered to plug the through groove 12 for stamping assembly between the rotating shaft and the iron core. The stroke of the triggering mechanism triggering the material taking component to move can be prior to the stroke of the iron core and the rotating shaft being butted, which is convenient for later material taking. After the support block 11, the clamping component one, the stamping component, and the clamping component two all move away from the assembled rotor, material taking is realized, and material taking is more convenient. And the stroke of the triggering mechanism driving the plugging component to move to plug the through groove 12 needs to be prior to the process of the stamping component contacting the rotating shaft to realize stamping forming with the iron core, so that the plugged support block 11 can provide a certain supporting force for the rotating shaft. And before stamping, the through groove 12 on the support block 11 is in a through state, and there will be no blocking substances affecting their forming.

[0052] In a further embodiment provided by the present invention, the stamping assembly includes a hydraulic rod 21 fixedly connected to the assembly frame 1. The bottom end of the hydraulic rod 21 is fixedly connected with a stamping plate 22. The hydraulic rod 21 is connected to an external power supply and a control switch. After the hydraulic rod 21 is powered off, it maintains the state before power-off, and the hydraulic rod 21 provides stable kinetic energy for the movement of the stamping plate 22 at the working position.

[0053] Furthermore, the second clamping assembly includes a connecting plate 31 vertically slidably connected to the assembly frame 1. A first rotating rod 32 is rotatably connected in the connecting plate 31. The bottom end of the first rotating rod 32 is fixedly connected with a second clamping arm 33. The second clamping arm 33 is an existing mature device for clamping a rotating shaft, and it clamps and fixes the rotating shaft through separate control and cooperation with the controller. The connecting plate 31 is fixedly connected to the stamping plate 22 through an elastic telescopic rod 34. A hole is provided on the connecting plate 31 and directly above the hydraulic rod 21 so that the hydraulic rod 21 can be directly fixedly connected to the top of the assembly frame 1; a fixed cylinder 35 and a blocking plate 36 are fixedly connected to the assembly frame 1. The blocking plate 36 is arranged in the stroke of the connecting plate 31 moving with the stamping plate 22. When the rotating shaft on the second clamping arm 33 is completely inserted into the iron core, the connecting plate 31 is blocked by the blocking plate 36 and no longer moves downward, while the stamping plate 22 will continue to move downward without being affected to perform the next stamping operation. A track groove 37 is provided in the fixed cylinder 35. A sliding rod 38 is fixedly connected to the first rotating rod 32. The sliding rod 38 is slidably connected in the track groove 37. The connecting plate 31 contacts the blocking plate 36 during its movement stroke. The track groove 37 is composed of a spiral part and a vertical part. The spiral part is arranged above the vertical part. When the sliding rod 38 enters the spiral part of the track groove 37, it will drive the first rotating rod 32 to rotate. When the first rotating rod 32 drives the rotating shaft on the second clamping arm 33 to rotate to directly above the iron core, the sliding rod 38 will enter the vertical part of the track groove 37.

[0054] Even further, the first linkage assembly includes a long strip plate 41 fixedly connected to the first rotating rod 32. A first connecting strip 42 is rotatably connected to the long strip. A first telescopic rod 43 is fixedly connected to the support block 11. The first telescopic rod 43 is rotatably connected to the connecting strip; the second linkage assembly includes a rotating plate 51 rotatably connected to the assembly frame 1. Both ends of the rotating plate 51 are rotatably connected with second connecting strips 52; a first moving plate 53 and a second moving plate 54 are respectively rotatably connected to the two second connecting strips 52. The first moving plate 53 is fixedly connected to the connecting plate 31. A T-shaped rod 55 is fixedly connected to the second moving plate 54. The T-shaped rod 55 is slidably connected to the support table. By providing the first linkage assembly and the second linkage assembly, the support block 11 has a process of moving horizontally and then moving upward. Conversely, during demolding, the support block 11 first moves downward to separate from the rotating shaft and then moves, which will not affect the reset movement of the first clamping assembly.

[0055] In an embodiment further provided by the present invention, the material picking assembly includes a support frame 61 fixedly connected to the assembly frame 1, and a base 62 is rotatably connected to the support frame 61; a wedge block 63 is slidably connected to the base 62, and a mechanical claw 64 is fixedly connected to the wedge block 63, and a spring 65 is arranged between the base 62 and the wedge block 63, and the elastic force of the spring 65 drives the wedge block 63 away from the base 62, and the top of the wedge block 63 is close to the end of the base 62 and is arranged in an inclined shape. The setting principle of the mechanical claw 64 is the same as that of the clamping arm 2 33, and the mechanical claw 64 is used to clamp and fix the outside of the iron core.

[0056] In the embodiment provided by the present invention, the sealing assembly is slidably connected to the moving block 71 in the support block 11, and a spring 2 72 is fixedly connected between the support block 11 and the moving block 71. The elastic force of the spring 2 72 drives the moving block 71 away from the support block 11. A sealing plate 73 is fixedly connected to the moving block 71, and the sealing plate 73 slides in the support block 11. When the stamping operation is performed, the sealing plate 73 moves to the through groove 12 to seal it. In other states, the sealing plate 73 is retracted inside the support block 11 and will not be affected by external contaminants.

[0057] In the solution further provided by the present invention, the trigger mechanism includes a wedge rod 81 fixedly connected to the stamping plate 22 and a trigger rod 82. The wedge rod 81 contacts the wedge block 63 during its movement. When the wedge rod 81 moves downward and contacts the wedge rod 81, the wedge block 63 is driven to move toward the inside of the assembly frame 1, and the contact stroke of the wedge rod 81 and the wedge block 63 takes precedence over the stroke of the iron core and the rotating shaft docking.

[0058] In the solution further provided by the present invention, a passive component is also provided on the assembly frame 1, and the passive component includes a vertical rod 91 slidably connected to the assembly frame 1, and a groove for the vertical rod 91 to move is required to be provided on the assembly frame 1; a contact plate 92 and an extension block 93 are fixedly connected to the vertical rod 91, the contact plate 92 is arranged at the top of the column, and the extension block 93 is arranged at the bottom of the vertical rod 91, and the trigger rod 82 contacts the contact plate 92 during the movement stroke, and a spring 94 is arranged between the contact plate 92 and the assembly frame 1, and the elastic force of the spring 94 drives the trigger rod 82 to move. Make the contact plate 92 away from the assembly frame 1; a pushing block 95 is slidably connected in the assembly frame 1, and multiple groups of connecting strips 96 are rotatably connected between the pushing block 95 and the extension block 93. When the column drives the extension block 93 to move downward, the pushing block 95 can be pushed to move toward the side of the support block 11 through the action of the connecting strip 96, and enter into the support block 11. When the pushing block 95 enters into the support block 11, a certain supporting force can be provided to the support block 11, and the blocking component inside the support block 11 can be triggered to move to block the through groove 12.

[0059] In a further solution provided by the present invention, the first clamping assembly includes two first clamping arms 10 slidably connected to the assembly frame 1. The first clamping arms 10 are arranged on the same principle as the second clamping arms 33. The mechanical claw 64 is used to clamp and fix the outside of the iron core.

[0060] In a further solution provided by the present invention, the guiding assembly includes gear rings 111 arranged on two second clamping arms 33. Two racks 112 are arranged in the assembly frame 1. During the upward movement of the two gear rings 111, they are respectively engaged with the corresponding racks 112. An idle rotation unit is further arranged between the two second clamping arms 33 and the corresponding gear rings 111. The idle rotation unit includes a ratchet rod 121 slidably connected to the second clamping arm 33. A fourth spring 122 is arranged between the ratchet rod 121 and the second clamping arm 33. Ratchet teeth 123 are arranged on the gear ring 111. The elastic force of the fourth spring 122 drives the ratchet rod 121 to engage with the ratchet teeth 123. By arranging the idle rotation unit, when the first clamping assembly moves upward, the gear ring 111 engages with the toothed plate and rotates, driving the first clamping assembly to rotate. On the contrary, when the first clamping assembly moves downward, the gear ring 111 engages with the toothed plate, and under the action of the idle rotation unit, the gear ring 111 rotates idly without driving the first clamping assembly to rotate.

[0061] Working principle: When working, the shaft and the iron core to be assembled are clamped and fixed with the clamping arm 2 33 and the clamping arm 1 10. The expansion grinder 13 is first started to enter the inside of the iron core, and the inner surface is polished and shaped. After that, the expansion grinder 13 is reset, and the external driving source is started to drive the clamping component 1 to drive the iron core to move up. At this time, the gear ring 111 in the clamping component 1 will mesh with the tooth plate in the assembly frame 1. At this time, the gear ring 111 rotates under the action of the tooth plate. When the gear ring 111 rotates, its The ratchet 123 arranged inside is stuck with the ratchet rod 121 on the clamping arm 10, so the gear ring 111 rotates to drive the clamping arm 10 to drive the iron core to rotate 90°, and at this time the gear ring 111 and the tooth plate move up, and the clamping arm 10 drives the rotated iron core to continue to move up while maintaining a vertical state with the operating surface. At the same time, the hydraulic rod 21 can be started to drive the stamping plate 22 to move down, and the stamping plate 22 moves down to pull the connecting plate 31 to move down synchronously through the elastic telescopic rod 34, and the connecting plate 31 moves down to drive the internal setting When the rotating rod 32 moves downward, it will first be affected by the spiral part of the track groove 37 inside the fixed cylinder 35, so that the rotating rod 32 drives the rotating shaft to rotate to the top of the iron core through the clamping arm 23, and then the sliding rod 38 enters the vertical part of the track groove 37, so that the rotating rod 32 moves downward with the downward movement of the stamping plate 22. When the connecting plate 31 moves downward, the rotating plate 51 is driven to rotate under the action of the moving plate 1 53 and the connecting strip 2 52 connected thereto, and the rotating plate After the rotation of 51, the support block 11 is driven to move upward through the influence of the second connecting strip 52 on the other side and the second moving plate 54 connected thereto, and when the rotating rod 1 32 rotates, the cooperation between the long strip plate 41 and the first connecting strip 42 drives the support block 11 to move horizontally. In this process, the movement trajectory of the support block 11 is to first move horizontally and upward synchronously, and then move upward until the support block 11 is against the bottom of the iron core. At this time, the bottom of the rotating shaft that is docked and enters the inside of the iron core is just stuck in the through groove 12 of the support block 11.

[0062] When the hydraulic rod 21 drives the stamping plate 22 to move downward, the wedge rod 81 provided on the stamping plate 22 will contact the wedge block 63, thereby triggering the wedge block 63 to drive the mechanical claw 64 to move to clamp the iron core to be docked. When the stamping plate 22 drives the connecting plate 31 to move downward, that is, after the rotating shaft is inserted into the iron core, the connecting plate 31 will be blocked by the blocking plate 36 and stop moving downward, while the stamping plate 22 continues to move downward. At this time, the support block 11 abuts against the bottom of the iron core. When the bottom of the rotating shaft inserted into the iron core just gets stuck in the through groove 12 of the support block 11, the trigger rod 82 provided on the stamping plate 22 will contact the contact plate 92 on the vertical rod 91 and push it downward. The downward movement of the vertical rod 91 drives the extension block 93 to move synchronously, and cooperates with the connecting strip three 96 to drive the pushing block 95 to slide horizontally. The pushing block 95 slides horizontally into the support block 11 and pushes the moving block 71 inside the support block 11 to move. The moving block 71 moves to push the sealing plate 73 to block in the through groove 12 and is located below the rotating shaft. While supporting the rotating shaft, the stamping plate 22 punches the rotating shaft so that the rotating shaft is assembled with the iron core;

[0063] During demolding, all parts are reset. The clamping arm one 10 in the clamping assembly one releases the clamping and fixing of the iron core, and the clamping arm two 33 in the clamping assembly two releases the fixing of the iron core. After the mechanical claw 64 maintains the clamping state, until the bottom of the rotating shaft after the assembly of the support block 11 moves, the wedge rod 81 is separated from the wedge block 63. The wedge block 63 is reset under the action of the spring one 65, and under the action of an external driving source, the base 62 on the support frame 61 drives the fixed assembly to rotate to realize the demolding and blanking operation.

[0064] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
