Description

Technical Field

[0001] The utility model relates to the field of disc motors, in particular to an auxiliary installation tool for a disc motor rotor. Background Art

[0002] Disc motors, also known as axial flux motors or disk motors, have the advantages of compact structure, high power density, high efficiency and low noise compared to traditional motors. They are widely used in various fields in modern industrial production.

Different models of disc motor rotors can also be switched and assembled by replacing different guide columns.

[0004] In the device, it is pointed out that the difficulty in assembling the existing disc motor lies in the length of the rotor shaft passing through the lower end cover. The precise passing length can ensure that the rotor is subjected to force balance between the two fixed stators when the motor rotates, and ensure a reasonable gap between the stator and the rotor. If the deviation is too large, the rotor and the stator interfere with each other, affecting the motor performance.

In addition, the installation of the mounting plate in the device is only installed by plugging the positioning pins and the pin holes, and the stability is poor.

A positioning component is provided on the upper surface of the support plate 5. The positioning component can fix the lower end covers of different diameters on the support plate 5, so that various types of disc motors can be installed, thereby enhancing the applicability of the device.

[0033] Reference Figure 1 - Figure 3The positioning assembly includes a slide bar 71, and a circular plate 73 is fixedly connected to the upper surface of the slide bar 71. The slide bar 71 and the circular plate 73 will move longitudinally synchronously. The upper surface of the circular plate 73 is penetrated and threadedly connected with a threaded rod 72. The rotation of the threaded rod 72 can drive the circular plate 73 to move longitudinally. The thread lead angle of the outer wall of the threaded rod 72 is less than five degrees. The threaded rod 72 has a self-locking property, which can ensure the stability of the position of the circular plate 73 when the threaded rod 72 does not rotate. A through groove is provided on the upper surface of the support plate 5. The through groove is provided in a circular shape and is located at the support plate 5. At the center position of the upper surface of the support plate 5, the inner wall of the through groove is fixedly connected with a connecting plate 8, which is approximately in the shape of a front sight and can provide support for the lower end cover and the lower stator.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The quick-release assembly includes an insert block 61, a slot 601 is provided on the lower surface of the support plate 5, the insert block 61 corresponds to the slot 601, the inner wall of the insert block 61 is elastically connected with a clamping block 63 through a compression spring 62, the upper surface of the clamping block 63 is fixedly connected with a shifting block 64, the clamping block 63 and the shifting block 64 will move synchronously, and the upper surface of the shifting block 64 protrudes from the upper surface of the insert block 61.

[0035] Reference Figure 1 - Figure 3The base 1 is set to be U-shaped, the sliding rod 71 passes through and is slidably connected to the upper surface of the support plate 5, sliding longitudinally, the bottom end of the threaded rod 72 is rotatably connected to the upper surface of the support plate 5, and the top of the threaded rod 72 is fixedly connected to a hand wheel for easy grasping. Grasping the hand wheel can easily drive the threaded rod 72 to rotate, and the upper surface of the positioning block 74 is fixedly connected to the lower surface of the circular plate 73. When the circular plate 73 moves longitudinally, it will drive the positioning block 74 to move longitudinally. The lower surface of the positioning block 74 is set to an inclined surface, the fixing plate 77 is set to an arc shape, and the upper surface of the fixing plate 77 is provided with a threaded groove. The upper surface of the connecting block 76 is set to an inclined surface. The inclined surface fits with the inclined surface of the connecting block 76, the slide groove 701 is opened on the inclined surface of the connecting block 76, the slider 75 is fixed on the inclined surface of the positioning block 74, the slider 75 is slidably connected to the inner wall of the slide groove 701, and the slider 75 will squeeze the slide groove 701 when it moves, thereby driving the connecting block 76 and the fixed plate 77 to move. There are four groups of slide rods 71, positioning blocks 74, connecting blocks 76, and fixed plates 77. The four groups of slide rods 71, positioning blocks 74, connecting blocks 76, and fixed plates 77 are arranged in a circular array with the center of the through groove as the origin, so that multiple groups of fixed plates 77 can be opened or contracted synchronously, thereby changing the position of the threaded groove on the fixed plate 77.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The lower surface of the plug block 61 is fixedly connected to the upper surface of the mounting plate 4, and the plug block 61 is inserted into the inner wall of the slot 601. The front end of the upper surface of the card block 63 is set as an inclined surface. When the plug block 61 is inserted into the slot 601, the inclined surface of the card block 63 will be squeezed, and the card block 63 will move backward and retract into the plug block 61. The lower surface of the card block 63 is set as a plane. When the insertion is completed, the plane of the lower surface of the card block 63 will contact the upper surface of the support plate 5. The shift block 64 passes through and is slidably connected to the upper surface of the plug block 61 and slides in the front and rear directions. The card block 63 passes through and is slidably connected to the front surface of the plug block 61. One end of the compression spring 62 is fixedly connected to the rear surface of the card block 63, and the other end of the compression spring 62 is fixedly connected to the inner wall of the rear side of the plug block 61. When the card block 63 moves backward, it will squeeze the compression spring 62 to generate a reaction force.

[0037] Working principle: Before using this device, first fix the lower end cover and the lower stator on the disc motor together, then align the slot 601 with the plug block 61 and move the support plate 5 downward to make the plug block 61 plug into the slot 601. During the plugging, the inclined surface of the block 63 will be squeezed, and the block 63 will move backward and retract into the plug block 61 to release the obstruction to the support plate 5, and will squeeze the compression spring 62 to generate a reaction force. When the plug block 61 is plugged into the slot 601, the support plate 5 will release the squeezing of the block 63, and at this time, the lower surface of the support plate 5 will fit with the upper surface of the mounting plate 4. After the squeezing of the block 63 is released, the reaction force of the compression spring 62 will push the block 63 to move forward, and the block 63 will be stuck on the upper surface of the support plate 5 to fix the support plate 5.

[0038] Then place the lower end cover on the connecting plate 8, and then grab the handwheel to drive the threaded rod 72 to rotate. The rotating threaded rod 72 will drive the circular plate 73 and the positioning block 74 to move longitudinally, and the longitudinally moving positioning block 74 will drive the slider 75 to move synchronously. Since the slider 75 slides in the inner wall of the slide groove 701, the slider 75 will squeeze the slide groove 701 when it moves, thereby causing the multiple groups of connecting blocks 76 and the fixed plate 77 to shrink or open synchronously. When the threaded holes on the fixed plate 77 are aligned with the threaded holes on the lower end cover, stop rotating the threaded rod 72, the device will be stabilized, and then use bolts to fix the lower end cover on the fixed plate 77 and keep it fixed. Since the multiple groups of fixed plates 77 can be opened or contracted synchronously, they can be suitable for the installation of lower end covers of different diameters, thereby improving the applicability of the device.

[0039] Then pass the lower end of the rotor through the lower end cover and the lower stator, and insert the lower end of the rotor into the guide column 2. At this time, there will be a large gap between the rotor and the lower stator. In order to adjust the gap to an appropriate value, the electric telescopic rod 3 can be started to drive the mounting plate 4, the support plate 5, the connecting plate 8, the lower end cover and the lower stator to move upward, thereby narrowing the gap between the rotor and the lower stator. When the gap is adjusted to an appropriate value, put on the shell and install the upper terminal and the upper stator on the shell to complete the installation. This design enables the device to be suitable for rotors with different lower end lengths.

[0040] When the support plate 5 needs to be removed, the shifting block 64 is shifted backward to drive the clamping block 63 to retract into the inserting block 61 to release the obstruction to the support plate 5, and then the support plate 5 can be removed.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
