Technical Field

[0001] The utility model relates to the technical field of air box processing, and more specifically, to an air box burr grinding tool structure. Background Art

[0002] Insulated fully enclosed inflatable metal switchgear (referred to as inflatable cabinet) adopts a combination of air insulation and sulfur hexafluoride gas compartment. It is compact and expandable, and is suitable for power distribution automation. The inflatable cabinet has the characteristics of compact structure, flexible operation, and reliable interlocking. It can achieve good use effects for various application occasions (especially places with harsh environments) and different user requirements. The gas box is a core component of the inflatable cabinet. In order to ensure the processing and production quality of the gas box, the gas box needs to be polished during processing to remove burrs. In the existing gas box mounting hole polishing process, most of the manual wiping and polishing operations are performed by operators holding sandpaper, which makes it difficult to quickly and thoroughly remove burrs. The polishing operation takes a long time, affecting the polishing quality and work efficiency of the gas box mounting hole. Based on this, the utility model designs an air box burr polishing tooling structure to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide an air box burr grinding tool structure to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A burr grinding tooling structure for an air box includes a transmission plate, an assembly screw and several bumps. The assembly screw is threadedly connected to the middle of the transmission plate. The end of the assembly screw is located above the transmission plate and is fixedly connected to a long hexagonal cap. The outside of the assembly screw is located below the transmission plate and is threadedly sleeved with a transmission nut. Several bumps are arranged on the side of the transmission plate. The outside of the bumps is fixedly sleeved with a sandpaper sleeve. Several roller assemblies are provided on the outside of the long hexagonal cap on the transmission plate.

[0006] As a preferred technical solution of the present invention, the number of the protrusions is four, and the four protrusions are distributed in a circular shape with equal intervals.

[0007] As a preferred technical solution of the present invention, the transmission disc and the protrusion are an integrally formed structure.

[0008] As a preferred technical solution of the present invention, the number of the roller assemblies is three, and the three roller assemblies are distributed in a circular shape with equal intervals.

[0009] As an optimal technical solution of the present invention, the roller assembly includes a positioning screw ring, a bearing and a limiting roller. A positioning screw is threadedly connected between the transmission disk and the positioning screw ring. The end of the positioning screw is fixedly connected with a short hexagonal cap. The outside of the positioning screw is located below the transmission disk and is threadedly sleeved with a positioning nut. The limiting roller is rotatably sleeved on the outside of the positioning screw ring through the bearing.

[0010] As a preferred technical solution of the present invention, the assembly screw and the positioning screw are both components made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model is implemented by sleeve of the hand drill on the outside of the transmission nut and the roller assembly extending into the air box mounting hole, so that the sandpaper sleeve on the outside of the protrusion contacts the peripheral surface of the air box mounting hole and the limiting roller in the roller assembly contacts the inside of the air box mounting hole. The hand drill is used to drive the transmission disk to rotate. When the roller assembly rotates with the transmission disk, the limiting roller can roll along the inside of the air box mounting hole, which can play a good limiting support role when the transmission disk rotates and is conducive to reducing the friction generated. When the protrusion rotates with the transmission disk, the sandpaper sleeve can semi-automatically grind the air box mounting hole, and there is no need for the operator to hold sandpaper for manual wiping and grinding operations, thereby facilitating rapid and thorough burr removal, which is conducive to shortening the time required for the grinding operation and ensuring the grinding quality and work efficiency of the air box mounting hole.
