Description

Technical Field

[0002] The rotor refers to a rotating body supported by bearings. The rotor in the motor is composed of a shaft iron core and a closed conductor embedded in the iron core. It produces high-speed rotational motion driven by the rotating magnetic field generated by the stator winding; rolling bearings are used at both ends of the rotor and are installed and fixed in the end cover of the motor casing.

[0003] For example, the Chinese utility model patent with application number: 202323408198.0, entitled "Assembly tool for producing DC motor rotor", discloses an assembly tool for producing DC motor rotor, including a base and a clamping component for fixing a workpiece, wherein the clamping component includes a bracket provided at the top of the base for support, a cylinder provided at the top of the bracket for providing power, a push rod provided at the bottom of the cylinder for driving, a sliding plate provided at the bottom of the push rod, and a movable through hole provided on one side of the sliding plate for providing a fixing space. The utility model uses a base, a screw, a clamping block and a mold, and the driving plate drives the clamping block to move through the support rod, so that the two clamping blocks can clamp and fix the two ends of the rod-shaped workpiece, thereby solving the problem that the mold structure is easy to loosen when the existing equipment is used to install the rotor, and the mold structure cannot be stably installed and fixed conveniently. The disassembly and replacement operation of the mold structure is relatively cumbersome, which is not conducive to the mold structure adapting to workpieces of different sizes, and affects the stability and practicality of the equipment in installing the workpiece.

[0004] The shortcomings of the prior art are that when the existing motor rotor is installed, the inside of the iron core is processed. If there are protrusions inside the iron core, it may affect the integrity of the shaft. When the rotor is assembled, the bottom of the external mold used to support the limit is fixed. During the assembly process, a certain amount of waste chips may fall. If accumulated for a long time, it may affect the position of the shaft inserted into the iron core, resulting in assembly failure. Summary of the invention

The support block 11, clamping assembly one, stamping assembly and clamping assembly two are all moved from the assembled rotor to realize material picking, which makes material picking more convenient. The stroke of the trigger mechanism driving the sealing assembly to move to seal the through slot 12 needs to be prioritized with the contact between the stamping assembly and the rotating shaft to realize the stamping forming process with the iron core, so that the support block 11 after blocking can provide a certain supporting force to the rotating shaft, and before stamping, the through slot 12 on the support block 11 is in a through state, and there will be no blocking material that affects the forming of the two.

[0052] In an embodiment further 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 to a stamping plate 22, the hydraulic rod 21 is connected to an external power supply and a control switch, the hydraulic rod 21 maintains the state before power failure after power failure, and the movement of the stamping plate 22 in the working position of the hydraulic rod 21 provides stable kinetic energy.

On the contrary, during demoulding, the support block 11 first moves downward and separates from the rotating shaft and then moves, which will not affect the resetting movement of the clamping component 1.

[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.

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 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 the solution further provided by the present invention, the clamping assembly 1 includes two clamping arms 10 slidably connected in the assembly frame 1. The setting principle of the clamping arm 10 is the same as that of the clamping arm 2 33. The mechanical claw 64 is used to clamp and fix the outside of the iron core.

[0060] In the solution further provided by the present invention, the guide assembly includes a gear ring 111 arranged on two clamping arms 33, and two racks 112 are arranged in the assembly frame 1. The two gear rings 111 are respectively engaged with the corresponding racks 112 during the upward movement; an idle unit is also arranged between the two clamping arms 33 and the corresponding gear rings 111, and the idle unit includes a ratchet rod 121 slidably connected in the clamping arm 33, a spring four 122 is arranged between the ratchet rod 121 and the clamping arm 33, and a ratchet 123 is arranged on the gear ring 111. The elastic force of the spring four 122 drives the ratchet rod 121 to engage with the ratchet 123. By setting the idle unit, when the clamping assembly moves up, the gear ring 111 engages with the tooth plate and rotates, driving the clamping assembly to rotate. Conversely, when the clamping assembly moves down, the gear ring 111 engages with the tooth plate, and under the action of the idle unit, the gear ring 111 idles without driving the 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 arranged 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 connected. When the stamping plate 22 drives the connecting plate 31 to move downward, that is, after the 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 is against the bottom of the iron core. At this time, after the bottom of the shaft connected to the inside of the iron core is just 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 to move downward. The vertical rod 91 moves downward to drive the extension block 93 to move synchronously, and cooperates with the connecting strip 3 96 to drive the push block 95 to slide horizontally. The push 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 and pushes the blocking 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 stamps the rotating shaft so that the rotating shaft and the iron core are assembled.

[0063] During demoulding, all parts are reset, the clamping arm 10 in the clamping component 1 releases the clamping fixation on the iron core, the clamping arm 2 33 in the clamping component 2 releases the fixation on the iron core, and the mechanical claw 64 maintains the clamping state until the support block 11 moves through the bottom of the rotating shaft after assembly, the wedge rod 81 separates from the wedge block 63, the wedge block 63 is reset under the action of the spring 1 65, and the base 62 on the support frame 61 is driven by the action of the external driving source to drive the fixed assembly to rotate to realize the stripping and unloading operation.

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
