[0019] The following describes several preferred embodiments of the present invention with reference to the accompanying drawings to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0020] In the drawings, components with identical structures are denoted by the same reference numerals, and components with similar structures or functions are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrary and are not limited by the present invention. For clarity, the thickness of components in some places in the drawings is appropriately exaggerated.

[0021] like Figure 1-9 As shown, this embodiment provides a pneumatic elastic burr removal device 10, which can remove burrs inside a workpiece that cannot be removed by conventional tools.

[0022] The pneumatic elastic burr removal device 10 includes a hollow body 1, a gas-powered impeller 5, a rotor 4, a fixing device 6 and a cutter head 3. The hollow body 1 is in the shape of a hollow cylinder. One end of the hollow body 1 can be connected to a compressed air device. The rotor 4 is arranged through the hollow body 1 and extends out of the outer wall of the hollow body 1. The gas-powered impeller 5 is arranged inside the hollow body 1 and fixed on the rotor 4. One end of the rotor 4 is connected to the fixing device 6, and the other end of the rotor 4 is connected to the cutter head 3. A spring 2 is connected between the cutter head 3 and the outer wall of the hollow body 1 to ensure that the cutter head 3 has floating space, so that the cutter head 3 can float up and down during chamfering, avoid excessive chamfering, and have a uniform chamfering effect on the inner hole. A chamfering edge is provided on the cutter head 3.

[0023] The pneumatic elastic burr removal device 10 further includes a joint 7 and an air pipe 8 . One end of the hollow body 1 is connected to the air pipe 8 via the joint 7 . The air pipe 8 can be connected to a compressed air device.

[0024] One end of the joint 7 is threadedly connected to one end of the hollow body 1 , and the other end of the joint 7 is a tapered joint, which is connected to the air pipe 8 , which is a threaded hose.

[0025] An exhaust baffle is provided at the other end of the hollow body 1 , and an exhaust hole is provided on the exhaust baffle. The overall cross-sectional area of the exhaust hole is less than half of the cross-sectional area of the hollow body 1 .

[0026] In this embodiment, the fixing device 6 is a plane bearing, which is arranged in a bearing mounting hole on the outer wall of the hollow body 1. One end of the rotor 4 has an outer convex portion, and the diameter of the outer convex portion is larger than the inner diameter of the plane bearing.

[0027] In other embodiments, the fixing device 6 may be a clip spring.

[0028] In this embodiment, a set screw mounting hole is provided on the side wall of the cutter head 3, a rotor mounting hole is provided at the bottom of the cutter head 3, the other end of the rotor 4 is inserted into the rotor mounting hole, and a set screw 9 is screwed into the set screw mounting hole to fix the cutter head 3 to the rotor 4.

[0029] In other embodiments, the other end of the rotor 4 may be threadedly connected to the cutter head 3 .

[0030] In other embodiments, the connector 7 may be a gas flow rate valve.

[0031] This embodiment also provides a method for using the pneumatic elastic burr removal device 10 as described above, comprising the following steps: Step 1: Connect one end of the hollow body 1 to a compressed air device; Step 2: Compressed air is introduced into the hollow body 1 to drive the gas-powered impeller 5 , which drives the rotor 4 and the cutter head 3 to rotate, thereby performing chamfering and deburring operations on the workpiece.

[0032] The assembly method of this embodiment is as follows: First, install the gas-powered impeller 5 into the hollow body 1; then, connect the rotor 4 to the gas-powered impeller 5 and the hollow body 1; then, use the fixing device 6 to fix the rotor 4; then, install the spring 2; then install the cutter head 3; finally, complete the installation of the joint 7 and the air pipe 8.

[0033] From the above description, it can be seen that the device of this embodiment has the following characteristics: one end of the device is connected to the gas source, and the other end is provided with an exhaust hole. The power comes from compressed gas, which enters the hollow body 1 to drive the gas-powered impeller 5, and then drives the rotor 4 and the cutter head 3 to rotate, thereby realizing the operation function of chamfering and deburring the workpiece.

[0034] Although certain components (e.g., the gas flow valve, control valve, muffler, switch, and oil-water separator) are not specifically labeled in the illustrations of this embodiment, this does not mean that this embodiment lacks the corresponding functions. It should be noted that this embodiment is not limited to the following: the connection method of the cutter head 3 can be threaded or jackscrewed; whether the rotor 3 uses a support device such as a bearing; and whether the connector 7 can be a gas flow valve or a conventional connector.

[0035] This invention effectively solves the problems of traditional manual deburring, including inconvenience, low efficiency, and high labor intensity. It is applicable to workpiece cavities, workpiece outlines, cylindrical outer surfaces, and hole perimeters, and is particularly effective in difficult-to-deburr locations such as cavities and cross-holes.

[0036] To address the difficulty of removing burrs in workpieces with multiple intersecting holes, this invention allows the tool to penetrate deep into the hole to perform chamfering and deburring, effectively resolving the inability of traditional tools to remove burrs within the hole, thereby improving production efficiency. The invention also incorporates an elastic device to prevent gnawing caused by hard contact between the tool and the workpiece, as well as uneven chamfering, further enhancing machining stability and reliability.

[0037] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
