Description

Technical Field

[0001] This utility model relates to the field of dynamic impeller balance detection technology, specifically a dynamic impeller balance detection clamping device. Background Technology

[0002] The impeller is the core component of the vacuum cleaner's air duct system. The motor inside the vacuum cleaner drives the impeller to rotate at high speed through a connecting shaft. When the impeller rotates at high speed, air enters through the air inlet and is finally thrown out by the impeller blades, thus generating suction power sufficient to clean up the debris.

[0003] To ensure the stability of the impeller at high speeds, optimize the performance of the vacuum cleaner, extend its service life, and improve the user experience, the moving impeller of the vacuum cleaner needs to undergo a balance test after production. In the process of balancing a moving impeller using a dynamic balancing machine, a clamping device is required to fix the impeller in place. Currently, a three-jaw chuck is commonly used to clamp the impeller hub. However, clamping the hub with a three-jaw chuck makes it difficult to effectively control the force, easily leading to hub deformation and damage. Furthermore, when the hub width is narrow, clamping is inconvenient, resulting in poor impeller stability. Hydraulic clamping requires regular maintenance of the hydraulic system, which is costly. Therefore, there is a need to provide a clamping device for balancing and testing moving impellers to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 A dynamic impeller balancing detection clamping device is installed on the outer surface of the main shaft 1 of the dynamic balancing machine and located on both sides of the dynamic impeller body 6. It includes a limiting disk 2, which is fixedly sleeved on the outer surface of the main shaft 1. An air inlet 602 is opened in the center of the upper cover of the dynamic impeller body 6. A conical sleeve 3 for locking into the air inlet 602 is provided on the inner side of the limiting disk 2. A friction plate 4 is provided on the side of the conical sleeve 3 away from the limiting disk 2. The front end of the outer surface of the spindle 1 is provided with an external thread 101, and the spindle 1 is threadedly connected to a fastening nut 5 through the external thread 101.

[0019] The tapered sleeve 3 has positioning pins 301 at both ends near the limiting plate 2. The limiting plate 2 has positioning holes 201 that cooperate with the positioning pins 301. When installing the tapered sleeve 3, the tapered sleeve 3 is pushed to slide along the main shaft 1 and move towards the limiting plate 2. When the positioning pins 301 on the tapered sleeve 3 are engaged in the positioning holes 201 on the limiting plate 2, the tapered sleeve 3 can be effectively prevented from rotating. The tapered sleeve 3 is easy to install and disassemble.

[0020] The impeller body 6 has a hub 601 on the inner side of the center of the base plate. The conical sleeve 3 has a hub groove 302 on the side away from the limiting plate 2. The friction plate 4 is fixedly installed inside the hub groove 302. By installing the friction plate 4 inside the hub groove 302, after the impeller body 6 is fixed, the conical sleeve 3 is inserted into the air inlet 602, which can effectively support the upper cover of the impeller body 6. At this time, the hub 601 of the impeller body 6 is inserted into the hub groove 302 and contacts the friction plate 4, which effectively increases the friction and ensures the stability of the impeller body 6.

[0021] The hub 601 extends outward through the center hole of the base plate of the impeller body 6. A pressure plate is fixedly installed inside the fastening nut 5. The center of the pressure plate of the fastening nut 5 has a groove 502 that matches the protruding part of the hub 601. When the fastening nut 5 is tightened so that the pressure plate contacts and presses against the base plate of the impeller body 6, the protruding part of the hub 601 can be effectively inserted into the groove 502 and contact the inner wall of the groove 502 by opening the groove on the pressure plate. This effectively increases the contact area between the pressure plate and the impeller body 6, and further ensures the stability of the impeller body 6.

[0022] The fastening nut 5 is provided with handles 501 on both sides. By providing handles 501, it is easy to drive the fastening nut 5 to move back and forth along the horizontal direction of the main shaft 1, so as to clamp or loosen the impeller body 6.

[0023] The working principle is as follows: First, install the conical sleeve 3. When installing the conical sleeve 3, push the conical sleeve 3 to slide along the main shaft 1 and move it closer to the limit plate 2. Then, when the positioning pin 301 on the conical sleeve 3 is engaged with the positioning hole 201 on the limit plate 2, the conical sleeve 3 can be effectively prevented from rotating. Then, the moving impeller body 6 is fitted on the outer surface of the conical sleeve 3. Turning the handle 501 can drive the fastening nut 5 to move horizontally along the main shaft 1 closer to the moving impeller body 6. In conjunction with the conical sleeve 3, the moving impeller body 6 is clamped. The operation is simple and saves time and effort.

[0024] Furthermore, after the moving impeller body 6 is fixed, the conical sleeve 3 is inserted into the air inlet 602, which can effectively provide internal support for the upper cover of the moving impeller body 6. At this time, the hub 601 of the moving impeller body 6 is inserted into the hub groove 302 and contacts the friction plate 4, which effectively increases the friction and ensures the stability of the moving impeller body 6. When the fastening nut 5 is tightened so that the pressure plate contacts and presses against the bottom plate of the impeller body 6, the protruding part of the hub 601 can be effectively inserted into the groove 502 and contact the inner wall of the groove 502 by opening a groove 502 on the pressure plate, thereby effectively increasing the contact area between the pressure plate and the impeller body 6 and further ensuring the stability of the impeller body 6.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
