Description

[Technical Field]

[0001] This utility model belongs to the field of assembly equipment technology, and in particular relates to a magnetic rotor assembly device for housing assembly. [Background Technology]

[0002] During the assembly of the rotor assembly and the housing, the rotor assembly must be precisely installed into the housing and sealed at the top opening of the housing with end caps, while ensuring the axial clamping effect of the end caps on the rotor assembly. Traditional assembly methods often rely on manual operation or semi-automated equipment, which has the following problems:

[0003] (1) Insufficient positioning accuracy: When manually placing the rotor assembly and end cover, operational errors can easily lead to deviations in the coaxiality of the components, affecting the assembly quality.

[0004] (2) Inefficient: The tooling entry and exit, component picking and placing, etc. rely on manual pushing, and lack stable support and rapid positioning mechanism for the tooling, resulting in long assembly cycle;

[0005] (3) Poor compatibility: Different models of rotor assemblies and end covers require matching special fixtures, and the equipment needs to be re-adjusted when changing models, resulting in high adaptation costs;

Detailed Implementation Methods

[0037] Example 1:

[0038] Please refer to Figures 1-7 This embodiment is a magnetic rotor assembly housing assembly device 100, which is used to install the rotor assembly 200 into the housing 300 and to seal the end cap 400 at the top opening of the housing 300; the end cap 400 axially presses the rotor assembly 200.

[0039] A magnetic rotor assembly housing assembly device 100 includes a worktable 1, a bearing positioning groove 2 disposed on the worktable 1 for bearing tooling, a shaft lifting mechanism 3 located at the bottom of the bearing positioning groove 2, a first bracket 4 disposed on the worktable 1, an end cap rotor clamping mechanism 5 fixed on the first bracket 4 and located above the bearing positioning groove 2, a rotor support mechanism 6 located on the worktable 1 and supporting the rotor assembly 200 after the rotor assembly 200 is lifted by the shaft positioning mechanism 3 to the end cap rotor clamping mechanism 5, and a tooling positioning mechanism 7 for positioning the tooling on the bearing positioning groove 2.

[0040] The bearing positioning groove 2 is used to support the first tooling 8 of the bearing housing 300 and the second tooling 9 of the bearing rotor assembly 200 and end cover 400. Several first support ball bearing sets 11 are provided on the worktable 1 on the inlet / outlet side of the bearing positioning groove 2, and a second support ball bearing set 21 is provided inside the bearing positioning groove 2 to cooperate with the first support ball bearing sets 11 and receive the tooling. When the first tooling 8 supporting the bearing housing 300 or the second tooling 9 supporting the bearing rotor assembly 200 and end cover 400 is fed into the bearing positioning groove 2, the arrangement of the first support ball bearing sets 11 and the second support ball bearing sets 21 greatly improves the convenience of tooling entry and exit.

[0041] Since the rotor assembly 200, end cap 400, and housing 300 will be assembled later, if the bottom of the first tooling 8 sits on the second support ball set 21, sliding displacement may easily occur, affecting the assembly. Therefore, a first cylinder 22 is also provided below the bearing positioning groove 2 on the worktable 1 to drive the second support ball set 21 to move up and down. Multiple second support ball sets 21 are movably embedded in the bearing positioning groove 2 and are collectively set on a first support plate 23. The first support plate 23 is connected to the movable end of the first cylinder 22, and the up and down movement is achieved by driving the first cylinder 22. When it is necessary to dock the first support ball set 11, the first cylinder 22 drives the second support ball set 21 to rise to the high position. After the tooling enters the bearing positioning groove 2, the second support ball set 21 descends to the low position, and the tooling sits on the bottom plate of the bearing positioning groove 2, achieving stable support for the bottom of the tooling.

[0042] Once the first tooling 8 or the second tooling 9 enters the bearing positioning groove 2 and sits on the bottom plate of the bearing positioning groove 2, the tooling positioning mechanism 7 precisely positions the first tooling 8 or the second tooling 9 to ensure accurate and stable positioning. The tooling positioning mechanism 7 has two sets, including a second cylinder 71 fixed to the bottom of the worktable 1 and a positioning rod 72 driven by the second cylinder 71 to move up and down. The first tooling 8 and the second tooling 9 are provided with positioning holes 81 that mate with the positioning rod 72.

[0043] The shaft lifting mechanism 3 serves two purposes: firstly, it pushes the rotor assembly 200 upward from the second fixture 9 and onto the end cover rotor clamping mechanism 5 when the end cover rotor clamping mechanism 5 picks up the rotor assembly 200; secondly, it lifts the bottom of the rotor assembly 200 upward when the end cover rotor clamping mechanism 5 assembles the rotor assembly 200 into the housing 300 on the first fixture 8, and simultaneously lowers the rotor assembly 200 into the housing 300 in coordination with the end cover rotor clamping mechanism 5. Specifically, the shaft lifting mechanism 3 includes a second bracket 31 fixed to the bottom of the worktable 1, a first driving member 32 fixed to the second bracket 31, a second support plate 33 that moves up and down under the influence of the first driving member 32, and a lifting shaft 34 fixed to the second support plate 33 and aligned with the central shaft hole of the rotor assembly 200. The first fixture 8, the second fixture 9, and the worktable 1 are all provided with clearance holes 82 for the lifting shaft 34 to pass through. The second bracket 31 is provided with a lead screw 35 extending along the Z-axis. The first driving member 32 drives the lead screw 35 to rotate via a synchronous belt. The second support plate 33 is provided with a lead screw nut 36 that cooperates with the lead screw 35 for transmission.

[0044] The end cap rotor clamping mechanism 5 is used to carry the end cap 400 and rotor assembly 200 from the second tooling 9; and includes a second driving member 51 fixed on the first bracket 4, a third support plate 52 driven by the second driving member 51 to move up and down, and a quick-change module 53 disposed on the third support plate 52. The quick-change module 53 is disposed on the third support plate 52 in a quick-change manner, which can quickly change the rotor assembly and end cap structure according to different models. The quick-change module 53 is mainly used to accurately position the end cap 400 and rotor assembly 200 and maintain a set posture for rotation into the housing 300. The quick-change module 53 includes a support base plate 531, a central positioning post 532 disposed on the support base plate 531 and used to extend into the central shaft hole of the rotor assembly 200 for positioning, a plurality of support positioning posts 533 disposed on the support base plate 531 and supporting the end cover 400 to maintain it in a set posture, and an end cover clamping assembly 534 disposed on the support base plate 531 and clamping the end cover 400 to stably maintain it in a set posture.

[0045] In this embodiment, to achieve a flexible fit between the central positioning post 532 and the rotor assembly 200, the central positioning post 532 is elastically floating on a mounting cylinder 535. The mounting cylinder 535 contains an elastic element (not shown in the figure) that holds the central positioning post 532 axially downward. However, when the rotor assembly 200 and end cap 400 are installed, the central positioning post 532 needs to remain rigid. Therefore, in this embodiment, the quick-change module 53 also includes a third cylinder 536 mounted on the support base plate 531 and a first support plate 537 driven by the third cylinder 536 to extend horizontally into the mounting cylinder 535 to restrict the axial extension and retraction of the central positioning post 532. When the central positioning post 532 needs to maintain axial floating extension and retraction, the first support plate 537 retracts horizontally to a clearance state. When the central positioning post 532 needs to remain rigid without axial extension and retraction, the first support plate 537 extends horizontally to restrict the shaft end of the central positioning post 532.

[0046] The rotor support mechanism 6 includes a third bracket 61 mounted on the workbench 1, a fourth cylinder 62 fixed on the third bracket 61, and a second support plate 63 driven by the fourth cylinder 62 to move horizontally. The front end of the second support plate 63 is provided with a U-shaped opening 631, which is open vertically. On the one hand, it allows the lifting shaft 34 to pass through, and on the other hand, it avoids the shaft structure at the bottom of the rotor assembly 200 to achieve stable support for the rotor assembly 200.

[0047] The working process of the magnetic rotor assembly housing assembly device 100 in this embodiment is as follows:

[0048] S1. Under the support and rolling of the first support ball group 11 and the second support ball group 21, the operator smoothly pushes the unloaded second tooling 9 from the inlet / outlet side of the bearing positioning groove 2 into the bearing positioning groove 2.

[0049] S2. The first cylinder 22 drives the second support ball assembly 21 to descend, and the second tooling 9 sits on the bottom plate of the bearing positioning groove 2; the positioning rod 72 in the tooling positioning mechanism 7 extends into the positioning hole 81 on the second tooling 9 to accurately position the second tooling 9.

[0050] S3. The operator places the rotor assembly 200 and the end cover 400 into the second tooling 9 one after the other.

[0051] S4. The end cover rotor clamping mechanism 5 is activated, the second driving component 51 drives the quick change module 53 to descend to the set height, the end cover clamping assembly 534 clamps the end cover 400, and at the same time, the central positioning column 532 extends into the rotor assembly 200.

[0052] S5. The shaft lifting mechanism 3 is started. The first driving component 32 drives the lifting shaft 34 to rise and press against the bottom end of the central shaft hole of the rotor assembly 200. The quick-change module 53 rises synchronously with the lifting shaft 34 to the set height.

[0053] S6, the rotor support mechanism 6 is activated, and the fourth cylinder 62 drives the second support plate 63 to extend and support the bottom of the rotor assembly 200.

[0054] S7. The lifting shaft 34 descends, the second support ball assembly 21 rises, and the operator moves the second tooling 9 out.

[0055] S8. The operator pushes the first tooling 8 carrying the housing 300 into the bearing positioning groove 2 in the same manner as described above, and places it on the bottom plate of the bearing positioning groove 2.

[0056] S9. The lifting shaft 34 rises, passes through the inside of the housing 300, and presses against the bottom of the central shaft hole of the rotor assembly 200 again, and the second support plate 63 is retracted.

[0057] S10, the lifting shaft 34 and the quick-change module 53 descend synchronously, placing the rotor assembly 200 into the housing 300, with the end cover 400 sitting on the top of the housing 300, completing the operation of installing the rotor assembly 200 and the end cover 400 into the housing 300, and obtaining the product assembly;

[0058] S11, quick-change module 53 rises, lifting shaft 34 falls, second support ball assembly 21 rises, and the first tooling 8 carrying product components is manually removed.

[0059] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
