Description

Technical Field

[0001] This utility model belongs to the field of PMI foam processing tool technology, specifically relating to a dust removal tool. Background Technology

[0002] Milling is a common machining process. Traditional milling tools are usually used to process metal materials. The chips generated during the cutting process are relatively heavy and fall onto the surface of the equipment. However, the powder generated by PMI foam after cutting is relatively light and tends to fly around during the cutting process. Furthermore, due to the small size of the particles, they tend to adhere to the surface of the workpiece or the tool during the machining process, thus affecting the cutting accuracy.

[0003] Therefore, it is necessary to design a dust removal tool with a simple structure that can greatly accelerate the workpiece processing progress and improve cutting efficiency. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a dust removal tool.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A dust removal tool includes a clamping handle and a cutting head. The clamping handle is divided into a top clamping part, a middle sliding part, and a bottom connecting part. The cutting head is threadedly connected to the bottom connecting part of the clamping handle. A bottom limiting platform is provided at the connection position between the middle sliding part and the bottom connecting part of the clamping handle. The middle sliding part includes two limiting planes formed on the clamping handle. A set of rotating blades is sleeved on the middle sliding part. The rotating blade set includes a bottom support, a rotating impeller, and a top limiting seat. Two locking screws are symmetrically provided on both the bottom support and the top limiting seat. The positions of the two locking screws correspond to the limiting planes. The rotating impeller is located between the bottom support and the top limiting seat. The rotating impeller includes a middle sleeve part and multiple dust removal blades. The rotating impeller is sleeved on the clamping handle through a sleeve part. The multiple dust removal blades are arranged around the center on the sleeve part.

[0006] Preferably, the top surface of the bottom support base has multiple lower inclined platforms with a higher left side and a lower right side along the center, and the bottom surface of the sleeve part in the rotating impeller has multiple upper inclined platforms with a lower left side and a higher right side along the center.

[0007] Preferably, the number of the lower inclined platforms is the same as the number of the upper inclined platforms, and the height and inclination are the same.

[0008] Preferably, the upper part of the cutter head and the outer ring surface of the bottom limiting platform are both provided with wrench buckles with the same structure.

[0009] The beneficial effects of this utility model are as follows: By setting a rotating blade assembly on the clamping handle, the clamping handle and the cutting head will simultaneously drive the rotating blade assembly to rotate during the grinding and chipping of PMI foam. This will generate a downward airflow through the dust removal blades, which will directly act on the cutting head and the part being processed, blowing the generated powder away from the workpiece and the cutting head. This will achieve the removal of foam debris during the processing, preventing it from adhering to the workpiece, affecting the processing, and reducing efficiency. Attached Figure Description

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: A dust removal tool, such as Figures 1-5As shown, the clamping handle 1 is divided into a top clamping part 3, a middle sliding part 4, and a bottom connecting part 5. The cutting head 2 is threadedly connected to the bottom connecting part 5 of the clamping handle 1. A bottom limiting platform 6 is provided at the connection position between the middle sliding part 4 and the bottom connecting part 5 of the clamping handle 1. The middle sliding part 4 includes two limiting planes 7 formed on the clamping handle 1. A set of rotating blades is sleeved on the middle sliding part 4. The rotating blade set includes a bottom support 8, a rotating impeller 9, and a top limiting seat 10. Two locking screws 11 are symmetrically provided on both the bottom support 8 and the top limiting seat 10. The positions of the two locking screws 11 correspond to the limiting planes 7. The rotating impeller 9 is located between the bottom support 8 and the top limiting seat 10. The rotating impeller 9 includes a middle sleeve part 12 and multiple dust removal blades 13. The rotating impeller 9 is sleeved on the clamping handle 1 through a sleeve part. The multiple dust removal blades 13 are arranged around the center on the sleeve part 12.

[0018] The top surface of the bottom support 8 has multiple lower inclined platforms 14 with a higher left side and a lower right side along the center, and the bottom surface of the sleeve part 12 in the rotating impeller 9 has multiple upper inclined platforms 15 with a lower left side and a higher right side along the center.

[0019] The number of lower inclined platforms 14 is the same as the number of upper inclined platforms 15, and their height and inclination are the same.

[0020] Both the upper part of the cutter head 2 and the outer ring surface of the bottom limiting platform 6 are provided with wrench buckles 16 with the same structure.

[0021] The principle of this utility model is as follows: During use, the required cutter head 2 is selected, and the required rotating blade assembly is selected according to the structure of the processed product. When the processed shape is relatively flat, a rotating blade assembly composed of longer dust removal blades 13 can be selected to increase the airflow. When the processed shape has grooves or other vertical heights, a rotating blade assembly with shorter dust removal blades 13 can be selected to avoid the dust removal blades 13 hitting the workpiece. When installing the rotating blade assembly, the bottom support 8, the rotating impeller 9, and the top limiting seat 10 are first sequentially placed on the clamping handle 1. The bottom support 8 and the top limiting seat 10 clamp the rotating impeller 9, and the lower inclined platform 14 and the upper inclined platform 15 interlock with each other. The bottom support 8 and the top limiting seat 10 are then fixed to the clamping handle 1 by the locking screw 11. When the clamping handle 1 rotates, it can drive the rotating blade assembly to rotate, thereby cleaning the powder generated during the processing.

[0022] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
