Example 3

[0029] This embodiment provides a method for deburring a part using the deburring tool, the deburring method comprising the following steps: Step S1. First, install the part to be deburred on the processing table, and then install the deburring tool on the processing spindle; Step S2. Set the operating parameters of the machining spindle in advance, use the machining spindle to control the rotation speed and machining feed rate of the deburring tool, and then start the intelligent CNC machining equipment to drive the deburring tool to move downward during the rotation process through the machining spindle; Step S3. When the deburring tool moves down to the part where the burrs need to be removed, the floating of the cutter head 6 is used to evenly float and remove the burrs of the part; during the deburring process, the speed of the machining spindle is controlled to be 200 to 300 rpm, and the deburring time is 3 to 5 seconds; Step S4: After deburring is completed, the deburring tool is retracted along the original path.

[0030] A floating deburring tool and a part deburring method according to the present invention are used. In a specific application process, an adjusting mechanism 7 is arranged in a connecting sleeve 2. Since the adjusting mechanism 7 includes a floating ring 71, a floating shaft 72, a limiting mechanism 73 and an elastic member 74, the elastic member 74 is embedded in the first accommodating cavity in the handle 1 and extends downward into the floating cavity to be in contact with the floating ring 71. The floating end of the floating shaft 72 is connected to the cutter head 6, and the connection end and the floating ring 71 are circumferentially nested with a gap. The limiting mechanism 73 includes a plurality of limiting blocks 731 and limiting grooves 732 matching the limiting blocks 731. Under the action of the elastic member 74, the floating ring 71 moves up and down along the limiting grooves 732 through the limiting blocks 731 in the limiting mechanism 73, thereby driving the cutter head 6 to float axially along the central axis of the connecting sleeve 2.

[0031] A avoidance groove 721 is provided in the connecting end of the floating shaft 72, a second accommodating cavity corresponding to the floating shaft 72 is provided at the front of the floating ring 71, an annular limiting groove 711 is provided in the second accommodating cavity, a steel ball 712 corresponding to the avoidance groove 721 is provided in the annular limiting groove 711, and a connecting spring 713 abutting against the steel ball 712 is also provided in the annular limiting groove 711, the avoidance groove 721 can allow the steel ball 712 to roll freely, and the connecting end of the floating shaft 72 forms a circumferential nested connection with a gap with the steel ball 712 in the annular limiting groove 711 through the avoidance groove 721; through the cooperation between the avoidance groove 721 and the steel ball 712, the cutter head 6 is driven to float radially along the central axis of the connecting sleeve 2.

[0032] Among them, the radial float refers to the fact that the tool can make slight movements along the radial direction perpendicular to the rotation axis during the processing. In the deburring process, radial float can be used to make the tool adapt to the unevenness of the part surface and achieve precise deburring effect. Axial float refers to the fact that the tool can make slight movements along the direction of the rotation axis during the processing. Axial float is also used to adapt to the unevenness of the part surface, especially when processing is required in the axial direction. Through radial and axial float, the tool can automatically adjust its position and direction according to the actual shape of the part, thereby ensuring the best contact and cutting state, which can not only reduce tool wear and processing errors, but also improve processing efficiency and processing quality.

[0033] By adopting the above-mentioned structure, the cutter head 6 can achieve radial and axial floating along the central axis of the connecting sleeve 2. When the grinding head 62 at the front end of the cutter head 6 is used to perform deburring and chamfering processes, the tool can compensate for the contact error between the tool and the part, thereby making the processing process smoother, so as to improve the processing stability and reduce the processing error. This can effectively solve the problem of removing burrs on the uneven contour of the part edge, burrs on the curved surface of the hole, and protrusions and burrs on the processing surface. By improving the processing quality and processing accuracy, the production efficiency and the deburring consistency of the product are improved, the stability of the product quality is guaranteed, and the processed products meet the requirements.

[0034] To sum up, the deburring tool and the parts deburring method described in the present invention are adopted, and the deburring tool is used for intelligent CNC machining equipment, which replaces manual handheld deburring. While reducing labor, it also greatly improves the machining efficiency, and can meet the burr and flash grinding processing needs of different parts. It has a simple structure and is convenient for assembly and disassembly. The products obtained by deburring not only have good consistency, but also high efficiency, stable product processing, high reliability, and are suitable for promotion and application.

10. The deburring method according to claim 9, characterized in that: In the deburring process of step S3, the rotation speed of the machining spindle is controlled to be 200 to 300 rpm, and the deburring time is 3 to 5 seconds.
