Description

Technical Field

[0001] This utility model relates to the field of rotor processing technology, and in particular to a rotor pressing bearing gear tooling. Background Technology

[0002] During rotor processing, the upper bearing, lower bearing, and gear need to be installed. In the current technology, each component requires a separate process, meaning that installing the upper bearing, lower bearing, and gear onto the rotor requires three processes, resulting in low overall processing efficiency. Utility Model Content

[0003] The technical solution to be solved by this utility model is to provide a rotor bearing gear tooling. Using this tooling, the upper bearing, lower bearing and gear can be installed on the rotor in one go, and the overall processing efficiency is high.

[0004] The technical solution adopted by this utility model is: a rotor pressing bearing gear tooling, wherein the lower bearing is provided with an inner ring support ring and an outer ring support ring, comprising a worktable, a placement seat fixed on the worktable for placing the gear and the lower bearing, a rotor seat on the worktable for placing the rotor, a pressing head on the worktable for placing the upper bearing and pressing the upper bearing, gear and lower bearing into the rotor, and a power mechanism for driving the pressing head to press down. The upper bearing located in the pressing head, the rotor located in the rotor seat, and the gear and lower bearing located in the placement seat are coaxially arranged. The placement seat is also provided with a positioning sleeve for positioning the gear, and the positioning sleeve is provided with a tooth tip for embedding into the tooth groove of the gear to position the gear, and the tooth tip extends upward to form an extension portion for abutting the inner ring support ring of the lower bearing.

[0005] Preferably, the extension has a notch at the position of the outer ring support ring of the lower bearing.

[0006] Preferably, the mounting base is also provided with a top pin for passing through the middle of the gear and thus positioning the gear, and a top pin spring for driving the top pin to reset.

[0007] Preferably, the rotor seat has a semi-circular cross-section, and a magnetic component for attracting the rotor is provided inside the rotor seat.

[0008] Preferably, the rotor seat and the placement seat are integrally formed.

[0009] Preferably, the workbench is provided with a guide post, a sliding plate sleeved on the guide post, and a guide post spring for providing a restoring force to the sliding plate, and the pressure head is fixed on the sliding plate.

[0010] Compared with the prior art, the present invention has the following advantages: the operation of this structure can simultaneously press the upper bearing, gear and lower bearing into the rotor, resulting in higher overall processing efficiency. Furthermore, when pressing down the bearing, the inner ring support ring of the lower bearing is subjected to force, thus the lower bearing is less likely to be squeezed and damaged.

[0011] A notch is provided at the position of the outer ring support ring of the lower bearing in the extension section. This way, the outer ring support ring of the lower bearing is not subjected to force when the bearing is pressed down, so the lower bearing as a whole is not easily damaged.

[0012] The top pin and top pin spring are installed so that the top pin can guide the gear when it is put into the positioning sleeve. After the upper bearing, gear and lower bearing are pressed into the rotor, the rotor can be pushed out by the top pin, which makes it easy to remove the parts.

[0013] With this rotor holder structure, the rotor can be easily inserted and readily attracted.

[0014] The rotor base and the mounting base are molded as one piece, which makes production and processing more convenient. In addition, the gear and lower bearing are placed below, and the rotor is placed above, which is also more convenient to use. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1:

[0023] A rotor bearing and gear pressing fixture is used to press an upper bearing 1, a lower bearing 2, and a gear 3 onto a rotor 4. The fixture includes a worktable 7, a guide column 19, a sliding plate 20, a pressing head 10, a power mechanism, a rotor seat 9, and a mounting base 8.

[0024] Workbench 7 is a fixed plate for mounting and securing other components;

[0025] There are two guide columns 19, which are fixed on both sides of the workbench 7 respectively.

[0026] The sliding plate 20 slides vertically on two guide posts 19, and a guide post spring 21 is also sleeved on the guide post 19. One end of the guide post spring 21 abuts against the sliding plate 20, and the other end of the guide post spring 21 abuts against the worktable 7.

[0027] The pressure head 10 is fixed on the sliding plate 20. A receiving groove is provided at its bottom. The upper bearing 1 can be received in the receiving groove. The bottom of the receiving groove is magnetic, so the upper bearing 1 can be attracted in the receiving groove and will not fall off.

[0028] The power mechanism is a cylinder, which is used to push the sliding plate 20 downward;

[0029] The placement seat 8 and the rotor seat 9 are integrated. The placement seat 8 is fixed on the worktable 7 and has a circular cavity inside. A positioning sleeve 11 is installed in the cavity. The shape of the middle part of the positioning sleeve 11 matches the shape of the gear 3 and can accommodate the gear 3. That is, the positioning sleeve 11 has multiple tooth tips 13, which can be embedded into the tooth groove 12 of the gear 3. The tooth tips 13 of the positioning sleeve 11 protrude upward to form an extension 14. The extension 14 can abut against the inner ring support ring 5 of the lower bearing 2 placed in the cavity. Furthermore, because the outer ring of the extension 14 has a notch 15, the extension 14 will not abut against the outer ring support ring 6 of the lower bearing 2. That is, only the inner ring support ring 5 of the lower bearing 2 is subjected to force. The rotor seat 9 is located above the placement seat 8. Its cross-section is a semi-circular ring, which can match the shape of the rotor. A magnetic element 18 is installed inside. When the rotor 4 is placed on it, it will be attracted by the magnetic element 18.

[0030] The working principle of this embodiment is as follows: The operator first places the upper bearing 1 into the pressure head 10 and magnetically attracts it. Then, the rotor 4 is placed into the rotor seat 9 and attracted by the magnetic component 18. Next, the gear 3 is placed into the positioning sleeve 11, and then the lower bearing 2 is placed above the positioning sleeve 11. At this time, the extension 14 of the positioning sleeve 11 abuts against the inner ring support ring 5 of the lower bearing 2. Then, the cylinder is controlled to work, driving the sliding plate 20 to press down. At this time, the pressure head 10 will also press down. First, the upper bearing 1 in the pressure head 10 squeezes the rotor 4. A part of the upper bearing 1 will be pressed into the rotor 4, and at the same time, it will drive the rotor 4 to press down. When it moves to a certain position, the rotor 4 will squeeze the gear 3. When the gear 3 is pressed into a certain position of the rotor 4, it will squeeze the lower bearing 2 and then press the lower bearing 2 into the rotor 4. When it is completely pressed to the bottom, the upper bearing 1, the lower bearing 2, and the gear 3 are all pressed into place, and the rotor 4 completes one pressing.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that the placement seat 8 in Embodiment 2 is also provided with a top pin 16 and a top pin spring 17 for driving the top pin 16 to reset. The top pin 16 is located in the middle of the positioning sleeve 11. When the gear 3 is installed, it can be positioned by the top pin 16 first, and then placed into the positioning sleeve 11. After the rotor 4 completes one pressing, the cylinder controls the sliding plate 20 to lift up, and the top pin 16 can push out the rotor 4 that has been pressed, making it convenient to remove the part.

[0033] Example 3:

[0034] The difference from Embodiment 1 is that in Embodiment 3, a bearing pad is also provided in the accommodating cavity of the placement seat 8. After the lower bearing 2 is placed into the placement seat 8, it abuts against the bearing pad, so that the lower bearing 2 is not easily damaged when it is pressed down.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0036] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
