Description

Technical Field

[0001] This utility model relates to the field of motor shaft technology, specifically a plug-in motor shaft. Background Technology

[0002] The motor shaft is an important transmission component inside the motor. It connects the motor's internal kinetic energy with the external mechanical system, enabling the machine to rotate and drive the load. The main function of the motor shaft is to convert electrical energy into mechanical energy and generate mechanical power through rotation. This power is then supported and transmitted to the load through components such as bearings, allowing it to work normally.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a plug-in motor shaft, which has the following advantages:

[0025] 1. This utility model, by setting an upper insertion positioning sleeve structure, allows the output shaft mechanism to be positioned and installed. When the output shaft mechanism is fixed, the adjusting screw rotates in the forward direction inside the positioning screw hole tube, causing the adjusting screw to move inward and abut against the middle of the outer wall of the I-shaped groove clamping plate. This allows the I-shaped groove clamping plate to be positioned and clamped at the annular groove of the upper I-shaped end post, preventing loosening. The periphery of the positioning sleeve post is equipped with a contact spring inside the hollow cone head. The contact spring can be positioned and deformed through the positioning sleeve post. The I-shaped groove clamping plate can be positioned and elastically abutted through the contact spring and the positioning sleeve post, thus making it more stable when abutting. The upper end of the I-shaped groove clamping plate has an insertion arc-shaped groove, allowing the upper semi-circular end to slide in. When the adjusting screw is not positioned, the I-shaped groove clamping plate can be positioned at a designated position through the contact spring and the positioning sleeve post, allowing the output shaft mechanism to slide in correspondingly through the upper semi-circular end. This allows for installation with only one hand, making assembly convenient.

[0026] 2. This utility model achieves positioning by setting an intermediate contact positioning mechanism. The upper and lower ends of the positioning sleeve of the intermediate contact positioning mechanism are fixedly connected to an upper insertion positioning sleeve and a lower insertion positioning sleeve, which can be installed and connected from both sides. When the inclined head screw rotates in the forward direction on the positioning sleeve, it can move inward. When the inclined head screw moves inward, it can abut against the movable inclined column and move outward. The movable inclined column can abut against the T-shaped contact column and move outward. The T-shaped contact column can abut against the upper and lower semi-circular ends, thereby achieving positioning. When the abutting force of the inclined head screw disappears, the T-shaped contact column can be elastically pulled back by the tension spring, thereby releasing the positioning force.

[0036] Example 1

[0037] This embodiment provides a technical solution: a plug-in motor shaft, such as... Figures 1-6 As shown, it includes a drive motor 1, an output shaft mechanism, a lower insertion positioning sleeve 2, a middle contact positioning mechanism, an upper insertion positioning sleeve, and an output rotating shaft mechanism.

[0038] The output shaft mechanism is installed and connected inside the drive motor 1. The output shaft mechanism rotates through the interaction of electromagnetic induction and magnetic field within the drive motor 1. The lower insertion positioning sleeve 2 is installed and connected to the front circumference of the output shaft mechanism. During rotation, the output shaft mechanism drives the lower insertion positioning sleeve 2 to rotate. The output shaft mechanism and the lower insertion positioning sleeve 2 can be quickly installed and removed. The intermediate abutment positioning mechanism is fixed to the front end of the lower insertion positioning sleeve 2. The intermediate abutment positioning mechanism can perform abutment positioning on the inner side of the front end of the lower insertion positioning sleeve 2. When sleeve 2 rotates, it can drive the intermediate contact positioning mechanism to rotate. The upper insertion positioning sleeve is fixed to the front end of the intermediate contact positioning mechanism. When the intermediate contact positioning mechanism rotates, it can drive the upper insertion positioning sleeve to rotate. The intermediate contact positioning mechanism can perform contact positioning on the inner side of the upper insertion positioning sleeve. The output shaft mechanism is installed and connected to the inner front end of the upper insertion positioning sleeve. When the upper insertion positioning sleeve rotates, it can drive the output shaft mechanism to rotate. The upper insertion positioning sleeve and the output shaft mechanism can be quickly installed and removed, making the installation more efficient.

[0039] like Figures 1-5 As shown, the lower insertion positioning sleeve 2 and the upper insertion positioning sleeve have the same structure and are symmetrical, so that the two sides can be installed and connected accordingly. The output shaft mechanism includes an output shaft rod 11, which is fixedly connected to the middle of the inside of the drive motor 1. The drive motor 1 interacts with the internal electromagnetic induction and magnetic field, which causes the internal output shaft rod 11 to rotate. The front end of the output shaft rod 11 is fixedly connected to a lower I-shaped end post 14. When the output shaft rod 11 rotates, it can drive the lower I-shaped end post 14 to rotate. The lower outer wall of the 14 is fixed with a lower positioning key block 12. The lower I-shaped end post 14 can drive the lower positioning key block 12 to rotate. The lower semi-circular end 13 and the lower I-shaped end post 14 are positioned and sleeved on the lower insertion positioning sleeve 2 through the lower positioning key block 12, so that they can be positioned and installed. The lower semi-circular end 13 is fixed to the front end of the lower I-shaped end post 14. The lower I-shaped end post 14 can be rounded and inserted into the interior of the lower insertion positioning sleeve 2 through the lower semi-circular end 13. The lower insertion positioning sleeve 2 can be effectively clamped and positioned by the internal symmetrical positioning clamping components.

[0040] The upper insertion positioning sleeve includes a hollow cone head 4, which is fixedly connected to the positioning sleeve 3 for stable installation. The lower inner side of the hollow cone head 4 has an abutment sleeve hole 43, which allows the T-shaped abutment post 431 to pass through the abutment sleeve hole 43 of the hollow cone head 4 for abutment. The upper inner side of the hollow cone head 4 has an assembly sleeve hole 42, and the inner side of the assembly sleeve hole 42 has a keyway sleeve hole 41 on the hollow cone head 4. The hollow cone head 4 is positioned and sleeved with an output rotating shaft mechanism through the keyway sleeve hole 41 and the assembly sleeve hole 42, which allows for corresponding positioning and installation connection. The inner sides of both ends of the hollow cone head 4 are fixedly connected with positioning clamping components, which can clamp from both sides.

[0041] The positioning and clamping assembly includes a positioning screw hole tube 44, which is fixedly connected to the outer wall of the hollow cone head 4 for stable placement. An adjusting screw 6 is rotatably connected to the inner center of the positioning screw hole tube 44. During fixing, the adjusting screw 6 rotates in the forward direction inside the positioning screw hole tube 44, causing it to move inward and abut against the middle of the outer wall of the I-shaped groove clamping plate 62. This allows the I-shaped groove clamping plate 62 to be positioned and clamped at the annular groove of the upper I-shaped end post 541, preventing loosening. Positioning sleeves 61 are sleeved on both sides of the adjusting screw 6 on the positioning screw hole tube 44. The positioning sleeves 61 can be positioned and moved within the positioning screw hole tube 44. The periphery of the positioning sleeves 61 is located on the hollow cone head 4. An internally installed anti-collision spring 64 is used. The anti-collision spring 64 can be positioned and deformed by the positioning sleeve 61. The anti-collision spring 64 and the positioning sleeve 61 are fixed to the I-shaped groove clamp plate 62. The I-shaped groove clamp plate 62 can be positioned and elastically resisted by the anti-collision spring 64 and the positioning sleeve 61, thus making it more stable when resisting. The upper end of the I-shaped groove clamp plate 62 is provided with an insertion arc groove 63, so that the upper semi-circular end 54 can be slidably inserted. When the adjusting screw 6 is not positioned, the I-shaped groove clamp plate 62 can be positioned in a designated position by the anti-collision spring 64 and the positioning sleeve 61, so that the output shaft mechanism can be slidably inserted through the upper semi-circular end 54. Thus, installation can be carried out with only one hand, which is convenient for assembly.

[0042] The inner end of the adjusting screw 6 abuts against the middle of the outer wall of the positioning sleeve 61, thereby allowing for selective abutment positioning.

[0043] The output shaft mechanism includes an output shaft body 5. A top end rod 53 is fixedly connected to the middle of the upper end of the output shaft body 5. When the output shaft body 5 rotates, it can drive the top end rod 53 to rotate. A bottom end rod 52 is fixedly connected to the lower end of the output shaft body 5. When the bottom end rod 52 rotates, it can drive the output shaft body 5 to rotate. An upper I-shaped end post 541 is fixedly connected to the lower end of the bottom end rod 52. When the upper I-shaped end post 541 rotates, it can drive the bottom end rod 52 to rotate. The upper outer wall of the 1 is fixed with an upper positioning key block 51. The upper I-shaped end post 541 can be positioned and sleeved in the keyway sleeve hole 41 and assembly sleeve hole 42 of the hollow cone head 4 through the upper positioning key block 51, so that it can be stably placed for installation. The lower end of the upper I-shaped end post 541 is fixed with an upper semi-circular end head 54. The upper I-shaped end post 541 can be slidably inserted and installed through the upper semi-circular end head 54. Moreover, when the upper semi-circular end head 54 is inserted into place, the upper semi-circular end head 54 contacts the bottom end inside the hollow cone head 4, so as to effectively determine the position.

[0044] In use, the output shaft mechanism rotates through the interaction of electromagnetic induction and magnetic field inside the drive motor 1. This rotation of the output shaft mechanism drives the lower insertion positioning sleeve 2 to rotate as well. The output shaft mechanism and the lower insertion positioning sleeve 2 can be quickly installed and removed. The intermediate contact positioning mechanism provides contact positioning on the inner front side of the lower insertion positioning sleeve 2. The rotation of the lower insertion positioning sleeve 2 drives the intermediate contact positioning mechanism to rotate, which in turn drives the upper insertion positioning sleeve to rotate. The intermediate contact positioning mechanism provides contact positioning on the inner side of the upper insertion positioning sleeve. The rotation of the upper insertion positioning sleeve then drives the output shaft mechanism to rotate. The quick installation and removal of the upper insertion positioning sleeve and the output shaft mechanism make installation more efficient.

[0045] Example 2

[0046] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 and Figure 6 As shown, to further better realize this utility model, the following configuration is specifically adopted: the intermediate contact positioning mechanism includes a positioning sleeve 3, with an upper insertion positioning sleeve and a lower insertion positioning sleeve 2 sequentially fixed to the upper and lower ends of the positioning sleeve 3, allowing for installation and connection from both sides. A beveled head screw 31 is rotatably connected to the center of the front end of the positioning sleeve 3 via a thread. When the beveled head screw 31 rotates forward on the positioning sleeve 3, it can move inward. Movable beveled columns 32 are sleeved on both sides of the inner end of the beveled head screw 31 inside the positioning sleeve 3. When the beveled head screw 31 moves inward, it can abut against... The movable inclined column 32 moves outward, and a T-shaped abutment column 431 is fixedly connected to the outer end of the movable inclined column 32 and sleeved inside the positioning sleeve 3. The movable inclined column 32 can abut against the T-shaped abutment column 431 as it moves outward. The T-shaped abutment column 431 can abut against the upper semi-circular end 54 and the lower semi-circular end, thereby achieving positioning. A tension spring 33 is installed at the connection between the T-shaped abutment column 431 and the movable inclined column 32. When the abutment force of the inclined head screw 31 disappears, the T-shaped abutment column 431 can be elastically pulled back by the tension spring 33, thereby releasing the positioning force.

[0047] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
