Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, and more specifically, to a device for grinding the inner wall of a waffle tube. Background Art

[0002] In the clean rooms of large clean electronic factories, a ventilation floor called "waffle board" is used. A large number of holes are arranged in the floor at a certain interval as the return air structure of the high-level clean workshop. The smoothness of the waffle tube wall not only affects the appearance, but more importantly, if the waffle tube wall is rough, it will cause dust to adhere to the electronic factory, lowering the environmental standards of the electronic factory. Therefore, when producing waffle tubes, it is often necessary to use a grinding device to grind the inner wall of the waffle tube. The grinding device currently used has a relatively complex structure, which is not conducive to popularization in factories.

[0003] In order to solve the above problems, a Chinese patent (publication number: CN218697553U) discloses a simple waffle tube wall grinding device, including a rotating power part, a transmission rod and a grinding tube. The output shaft of the rotating power part is fixedly connected to one end of the transmission rod through a connector, and the other end of the transmission rod is connected to the grinding tube through a connecting assembly. The connecting assembly is used to adjust the installation position of the grinding tube on the transmission rod.

[0004] Although the above technical solution solves the problem that the current waffle cone grinding device is relatively complex in structure and not conducive to popularization in factories by setting a rotating power part to drive the grinding cylinder to rotate and insert the grinding cylinder into the waffle cone for grinding, the inventor found in the process of implementing the above technical solution that it is impossible to adjust the diameter of the grinding component to adapt to waffle cones of different sizes, but it is necessary to prepare grinding cylinders of various diameters in advance for replacement, which increases the complexity and cost of grinding to a certain extent. Utility Model Content

[0005] The utility model aims to provide a waffle cone inner wall grinding device, which solves the problem that the existing grinding device cannot adjust the diameter of the grinding component, resulting in increased grinding complexity and grinding cost.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a waffle cone inner wall grinding device, including an operating handle, one end of which is fixedly connected to a protective plate, and a connecting tube is provided on the side of the protective plate away from the operating handle; a driving component, which is arranged between the operating handle and the connecting tube, and the driving component is used to drive the connecting tube to rotate; there are two grinding blocks, which are symmetrically arranged on both sides of the connecting tube; an adjusting component, which is arranged between the connecting tube and the two grinding blocks, and the adjusting component is used to adjust the distance between the two grinding blocks.

[0007] The working principle of this technical solution is as follows: when in use, first control the adjustment component according to the inner diameter of the waffle tube to be polished to adjust the distance between the two polishing blocks. After the adjustment is completed, the worker can hold the operating handle and extend the two polishing blocks into the inner side of the waffle tube so that the two polishing blocks are in contact with the inner wall of the waffle tube, and then start the driving component so that the two polishing blocks begin to polish the waffle tube.

[0008] In summary, the utility model has the following beneficial effects:

[0009] Compared with the prior art, the utility model provides a waffle cone inner wall grinding device, which adjusts the distance between the two grinding blocks by setting an adjustment component to adapt to waffle cones of different sizes, without the need to prepare grinding cones of various specifications in advance for replacement. This saves a lot of economic costs and reduces the time cost required for disassembly during replacement, effectively improving the grinding efficiency.

[0010] Furthermore, the driving assembly includes a driving motor, an output shaft of which passes through the protective plate and is fixedly connected to the connecting cylinder through a connector.

[0020] The following is combined with Figure 1 —4 The utility model is further described in detail.

[0021] like Figure 1 As shown, an embodiment of the utility model proposes a waffle cone inner wall grinding device, including an operating handle 7, one end of which is fixedly connected to a protective plate 6, and a connecting tube 2 is provided on the side of the protective plate 6 away from the operating handle 7; a driving component, which is arranged between the operating handle 7 and the connecting tube 2, and the driving component is used to drive the connecting tube 2 to rotate; a grinding block 14, which has two pieces, and the two grinding blocks 14 are symmetrically arranged on both sides of the connecting tube 2; an adjusting component, which is arranged between the connecting tube 2 and the two grinding blocks 14, and the adjusting component is used to adjust the distance between the two grinding blocks 14.

[0022] The specific working process is: first, according to the inner diameter of the waffle tube to be polished, the adjustment component is controlled to adjust the distance between the two polishing blocks 14. After the adjustment is completed, the worker can hold the operating handle 7 and extend the two polishing blocks 14 into the inner side of the waffle tube so that the two polishing blocks 14 are in contact with the inner wall of the waffle tube, and then start the driving component so that the two polishing blocks 14 start to polish the waffle tube.

[0023] In this embodiment, the distance between the two grinding blocks 14 is adjusted by setting an adjustment component to adapt to waffle cones of different sizes, without the need to prepare grinding cones of various specifications for replacement in advance.
