Description

Technical Field

[0001] This utility model relates to the field of grinding devices, specifically a grinding device for the bottom plate of a vacuum cleaner impeller. Background Technology

[0002] With the advancement of technology, vacuum cleaners have entered thousands of households. The suction power generated by the motor inside the vacuum cleaner driving the impeller to rotate can pick up the garbage on the floor as the vacuum cleaner passes, improving the efficiency of floor cleaning and reducing physical exertion. The motor inside the vacuum cleaner drives the impeller to rotate at high speed through the 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 garbage. The impeller base plate has a reserved groove for the impeller to be installed and riveted.

[0003] However, due to the small size of the impeller base plate, it is inconvenient to perform a smooth grinding process on the side surface when using a handheld grinding device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a grinding device for the bottom plate of a vacuum cleaner impeller, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a grinding device for the bottom plate of a vacuum cleaner impeller, including a bottom plate positioning sleeve, an insertion hole inside the bottom plate positioning sleeve, a limiting groove array on the outer side wall of the bottom plate positioning sleeve, a support plate inside the limiting groove, a return spring connected below the support plate inside the limiting groove, a positioning screw hole array inside the support plate, a limiting screw below the positioning screw hole, a support base below the bottom plate positioning sleeve, a vertical rod installed on the upper surface of the support base inside the insertion hole, a grinding mechanism above the vertical rod, and a grinding disc connected to one end of the grinding mechanism via a spring.

[0006] As a further improvement of this utility model: a hexagonal insert rod is installed at the other end of the grinding mechanism, a hexagonal insertion hole is opened on the upper surface of the upright rod corresponding to the position of the hexagonal insert rod, and a limit pad is installed on the outer side of the upright rod corresponding to the position of the lower surface of the base plate positioning sleeve.

[0007] As a further improvement of this utility model: a base plate to be ground is provided on the outer side of the upper end of the base plate positioning sleeve.

[0008] As a further embodiment of this utility model: the base plate positioning sleeve is a conical mechanism component, and the support plate is fixedly connected to the reset spring.

[0009] As a further improvement of this utility model, the limiting screw is engaged and fixedly connected with the positioning screw hole.

[0010] As a further embodiment of this utility model: the grinding mechanism is engaged with the hexagonal insertion hole via the hexagonal insertion rod, and a rotating bearing is provided on the lower surface of the base plate positioning sleeve above the limiting pad.

[0011] As a further improvement of this utility model, the support plate is slidably connected to the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The conical base plate positioning sleeve can accommodate base plates of different sizes to be ground. The base plate positioning sleeve uses a support plate to position the base plate to be ground, and then makes frictional contact with the grinding mechanism as a whole, which can ensure the flatness of the grinding surface and facilitate the grinding process.

Detailed Implementation

[0015] 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.

[0016] like Figure 1-5 As shown, this embodiment provides a grinding device for the bottom plate of a vacuum cleaner impeller, including a bottom plate positioning sleeve 1. The bottom plate positioning sleeve 1 is a conical mechanism component. An insertion hole 106 is provided inside the bottom plate positioning sleeve 1. Limiting grooves 101 are arrayed on the outer side wall of the bottom plate positioning sleeve 1. A support plate 103 is disposed inside the limiting groove 101. The support plate 103 is slidably connected to the limiting groove 101. A return spring 102 is connected below the support plate 103 inside the limiting groove 101. Plate 103 is fixedly connected to reset spring 102. Positioning screw holes 104 are arrayed inside the support plate 103. A limit screw 105 is provided below the positioning screw hole 104. The limit screw 105 is engaged and fixedly connected with the positioning screw hole 104. A support base 2 is provided below the bottom plate positioning sleeve 1. A vertical rod 201 is installed inside the insertion hole 106 on the upper surface of the support base 2. A grinding mechanism 4 is provided above the vertical rod 201. One end of the grinding mechanism 4 is connected to a grinding disc 401 by a spring.

[0017] like Figure 2-3 As shown, in this embodiment, a hexagonal insert rod 402 is installed at the other end of the grinding mechanism 4. A hexagonal insertion hole 203 is provided on the upper surface of the upright rod 201 corresponding to the position of the hexagonal insert rod 402. A limiting pad 202 is installed on the outer side of the upright rod 201 corresponding to the position of the lower surface of the base plate positioning sleeve 1. The grinding mechanism 4 is engaged and locked with the hexagonal insert rod 402 and the hexagonal insertion hole 203. A rotating bearing is provided on the lower surface of the base plate positioning sleeve 1 above the limiting pad 202. A base plate 3 to be ground is provided on the outer side of the upper end of the base plate positioning sleeve 1.

[0018] The working principle of this utility model is as follows: During use, the base plate 3 to be ground is fitted entirely onto the base plate positioning sleeve 1. After adjusting the riveting holes of the base plate 3 to align with the positioning screw holes 104 at different positions on the support plate 103, the limiting screw 105 is fully engaged and installed in the positioning screw hole 104. The upper end of the limiting screw 105 will limit the base plate 3 to be ground. Then, by pressing the base plate 3 upwards, the support plate 103 is controlled to move at different positions on the base plate positioning sleeve 1. After positioning, the hexagonal insert 402 at the end of the grinding mechanism 4 is inserted into the hexagonal socket 203. The grinding disc 401 is then pulled downward to extend and retract the internal spring. Once the grinding disc 401 contacts the side surface of the base plate 3 to be ground, the base plate positioning sleeve 1 is rotated on the outside of the upright 201. The grinding mechanism 4 is then limited inside the upright 201. Therefore, the grinding disc 401 and the side surface of the base plate 3 to be ground can be made into stable contact to perform a good grinding process on the side surface.
