Description

Technical Field

[0001] This application relates to the technical field of motor production equipment, specifically a rotor press-fitting tooling. Background Art

[0002] The motor rotor is a rotating component in the motor. The motor consists of two parts, the rotor and the stator, and is a device used to convert electrical energy into mechanical energy. When producing such motors, it is necessary to press-fit the rotating shaft into the central hole of the die-casting part with an interference fit. At this time, a rotor press-fitting device is required to perform the press-fitting operation;

[0003] For example, the patent with the publication number CN103707044B specifically discloses a multi-station press-fitting machine. By setting a feeding device, it can automatically unload the completed motor rotor from the bearing torsion piece die holder after the press-fitting is completed, overcoming the difficulty of manual unloading and reducing the labor intensity of workers.

[0004] In the above patent, the press-fitting machine is provided with a turntable and a pressure device, so that multiple groups of rotors on the turntable can be continuously press-fitted, increasing the press-fitting efficiency. However, since the pressure device is arranged on one side of the turntable, when the pressure device applies pressure to the turntable, only one side of the turntable is stressed. After long-term operation, the turntable may tilt, which may cause increased wear of the turntable and other connecting components, thereby shortening the service life of the equipment. In addition, the tilting of the turntable may also cause the position and angle of the rotor to become inaccurate, affecting the assembly accuracy and quality. Especially when accurately positioning and press-fitting the rotor, the tilted turntable will reduce the accuracy of the rotating shaft during the assembly process. Therefore, it is necessary to provide a rotor press-fitting tooling to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a rotor press-fitting tooling to achieve the effect of supporting the turntable when press-fitting the rotor and preventing the turntable from tilting.

[0007] The technical solution adopted by this application to solve its technical problems is as follows: a rotor press-fit tooling, including a base; a press-fit assembly, which is arranged on the top of the base. The press-fit assembly includes a press, and the press has a punch; a rotating assembly, which is arranged on one side of the press-fit assembly. The rotating assembly includes a rotating motor, and a turntable is installed at the output end of the rotating motor. At least two groups of mounting grooves are arranged on the turntable; a supporting assembly, which is arranged on one side of the rotating assembly. The supporting assembly includes a first cylinder, and the first cylinder is installed on one side of the rotating motor; a clamping block, which is fixedly installed at the output end of the first cylinder; a slideway, which is arranged on one side of the first cylinder, and the first cylinder is adapted to the size of the clamping block.

[0008] Further, a notch is provided at the center of the clamping block, and the size of the notch is larger than that of the mounting groove.

[0009] Further, at least two groups of chutes are arranged at the bottom of the turntable, and the size of the chutes is adapted to the size of the clamping block.

[0010] Further, a blanking assembly is arranged on one side of the base away from the supporting assembly. The blanking assembly includes a second cylinder, and a top plate is fixedly installed at the output end of the second cylinder.

[0011] Further, a blanking channel is arranged on one side of the second cylinder, and one end of the blanking channel is close to the turntable.

[0012] The beneficial effect of this application is as follows: for the rotor press-fit tooling provided by this application, by setting the supporting assembly, when the rotor is performing the press-fit operation, the turntable will not tilt due to excessive external pressure, enabling it to stably bear the pressure applied during the stamping process, ensuring the balance and stability of the turntable during the operation process, and thus improving the working efficiency and accuracy of the equipment.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0024] As Figure 1 - Figure 2 shown, this application provides a rotor shaft-pressing tooling, including a base 1, which is arranged in a motor processing factory. A rotating component 2 is arranged on the top of the base 1. The rotating component 2 is used to place the rotor and drive the rotor to feed. At the same time, a press-fitting component 3 is arranged on one side of the rotating component 2. The press-fitting component 3 is used to press-fit the bearing of the rotor so that the rotor meets the production requirements;

[0025] The press-fitting component 3 includes a fixed frame 31, which is fixedly installed on the top of the base 1. At the same time, a press 32 is installed on the top of the fixed frame 31. A punch 33 is arranged at the bottom of the press 32. The punch 33 is adapted to approach or move away from the base 1 under the drive of the press 32;

[0026] As Figure 2 - Figure 3As shown in the figure, the rotating assembly 2 includes a rotating motor 21 which is fixedly installed on one side of the fixing frame 31. At the same time, a turntable 22 is fixedly installed at the output end of the rotating motor 21. The turntable 22 is adapted to rotate driven by the rotating motor 21. Multiple groups of mounting grooves 23 are provided on the turntable 22. The mounting grooves 23 penetrate through the turntable 22, and sponges are provided on the inner walls of the mounting grooves 23. The mounting grooves 23 are used to fix the rotor. After the turntable 22 is installed, at least one group of mounting grooves 23 is located at the bottom of the punch 33;

[0027] When the rotor needs to be pressed, first place the rotor into the mounting groove 23, then place the bearing inside the rotor. At the same time, turn on the rotating motor 21, so that the rotor is driven by the turntable 22 to the bottom of the press-fitting assembly 3. At this time, the press 32 can be controlled to move, so that the punch 33 contacts the bearing and presses it into the rotor, thus completing the press-fitting operation of the bearing.

[0028] As Figure 3 shown in the figure, a support assembly 4 is provided below the punch 33 at the top of the base 1. The support assembly 4 includes a first cylinder 41 which is installed on one side of the rotating motor 21. A clamping block 43 is fixedly installed at the output end of the first cylinder 41 for supporting the bottom of the turntable 22. And there is a notch in the center of the clamping block 43, so that the clamping block 43 will not contact the rotor when supporting the turntable 22;

[0029] At the same time, a slideway 42 is provided on one side of the first cylinder 41. The clamping block 43 is adapted to slide in the slideway 42. Multiple groups of sliding grooves 24 adapted to the clamping block 43 are provided on the bottom of the turntable 22. The sliding grooves 24 are used to guide the clamping block 43;

[0030] When the turntable 22 drives the rotor to rotate to the bottom of the punch 33, by controlling the first cylinder 41 to drive the clamping block 43 to extend forward, so that the clamping block 43 enters the sliding groove 24. At this time, the turntable 22 is supported by the clamping block 43. When the pressing starts, the punch 33 contacts the rotor and applies pressure to the turntable 22. But since the turntable 22 is supported by the clamping block 43 at this time, the turntable 22 will not tilt during the stamping process, ensuring the accuracy and reliability of the stamping operation.

[0031] As Figure 4 shown in the figure, a blanking assembly 5 is provided on one side of the base 1 away from the support assembly 4. The blanking assembly 5 includes a second cylinder 51. A top plate 52 is fixedly installed at the output end of the second cylinder 51. A sponge is provided on the top of the top plate 52. The top plate 52 is used to contact the rotor after the press-fitting is completed, for ejecting the rotor from the mounting groove 23, making the blanking of the rotor more convenient;

[0032] Meanwhile, a blanking channel 53 is provided on one side of the second cylinder 51. One end of the blanking channel 53 is close to the turntable 22, and the other end is connected to an external collection mechanism. After the rotor is press-fitted, the rotor is ejected from the installation groove 23 by the top plate 52. At this time, the rotor will move into the winding box through the blanking channel 53 to complete the storage work of the material and the centralized processing of the variant staff.

[0033] In summary, by setting the support assembly 4, the turntable 22 will not tilt due to excessive external pressure during the press-fitting operation of the rotor, enabling it to stably bear the pressure applied during the stamping process, ensuring the balance and stability of the turntable 22 during the operation process, and thus improving the working efficiency and accuracy of the equipment.

[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
