[0027] By adopting the above technical solution, when the burrs on the edge of the weld on the welded part are harder, the electromagnet 14 is turned on, so that the sliding part 7 and the magnetic pole surface 11 at the end of the electromagnet 14 are adsorbed and fixed, so that there is no elastic movement between the sliding sleeve 3 and the fixed sleeve 2, and when the tool 5 encounters harder burrs, there will be no telescopic movement, thereby achieving a better grinding effect and improving the product processing quality.

[0028] Furthermore, a slide groove 10 is provided on the inner side of the vertical plate 15 , the inner wall of the slide groove 10 contacts the outer wall of one end of the sliding member 7 , the other end of the sliding member 7 is fixedly connected to the sliding sleeve 3 , and the sliding member 7 is made of iron or steel.

[0029] By adopting the above technical solution, when the electromagnet 14 is not enabled, the sliding part 7 and the sliding groove 10 move along the movement direction of the sliding sleeve 3, so that the tool 5 on the tool handle body 1 with a telescopic structure can be flexibly adjusted to the different weld positions of special-shaped welded parts, and can perform position compensation for the uneven frame caused by thermal expansion and contraction of the edge welding frame, thereby improving the grinding effect.

[0030] Furthermore, a first dustproof sheet 12 and a second dustproof sheet 13 are provided on the inner side of the opening of the slide groove 10 , and the slide groove 10 and the installation cavity 16 are in a communicating state.

[0031] By adopting the above technical solution, the first dustproof sheet 12 and the second dustproof sheet 13 respectively arranged on the sliding member 7 can prevent waste chips from entering and adhering to the chute 10, thereby avoiding affecting the sliding efficiency of the sliding member 7 and the chute 10.

[0032] Furthermore, the first dustproof sheet 12 has an accordion structure, one end of the first dustproof sheet 12 is fixed to the vertical plate 15 by bolts, and the other end of the first dustproof sheet 12 is fixed to the sliding member 7 by bolts. The structure of the first dustproof sheet 12 is consistent with the structure of the second dustproof sheet 13.

[0033] By adopting the above technical solution, the first dustproof sheet 12 and the second dustproof sheet 13 can be easily disassembled by loosening the bolts between the first dustproof sheet 12 and the sliding member 7 and the sliding groove 10, so as to facilitate the replacement or maintenance of the installation components of the installation cavity 16 in the vertical plate 15.

[0035] Furthermore, the power controller 8 includes a control panel and an inner cavity for storing batteries, and the power controller 8 is electrically connected to the electromagnet 14 .

[0036] By adopting the above technical solution, when the electromagnet 14 is needed, the power of the electromagnet 14 and the power controller 8 is turned on by operating the control panel, so that the electromagnet 14 adsorbs the sliding part 7, completes the fixing work of the sliding sleeve 3, and makes the sliding sleeve 3 and the fixed sleeve 2 no longer elastically move, so that the tool 5 at one end of the sliding sleeve 3 can successfully complete the grinding work of the harder burrs.

[0037] Furthermore, a reducer sleeve 4 for loading and unloading a tool 5 is provided at the end of the sleeve 3, an inner side of an opening at one end of the reducer sleeve 4 is provided with an internal thread, and an outer thread connected to the reducer sleeve 4 is provided at the end of the sleeve 3, and the tool 5 is a carbide rotary file.

[0038] Working principle: First, after the friction stir welding of the welded parts is completed, the handle body 1 equipped with the tool 5 is placed above the welded parts, and then the drive member connected to the handle body 1 on the stirring welding equipment drives it to rotate, so that the tool 5 grinds the burrs on the welded parts. At this time, the electromagnet 14 on the stop member 6 is in a non-working state, and the sliding member 7 can move in the sliding groove 10 on the vertical plate 15 along the movement direction of the sliding sleeve 3, and can flexibly adjust the position of the tool 5 according to different weld positions on the special-shaped welded parts, and can compensate for the uneven frame caused by the thermal expansion and contraction of the welding frame, thereby improving the grinding effect; when there are harder burrs on the welded parts, the electromagnet 14 is energized through the power controller 8, so that the magnetic pole surface 11 at one end of the electromagnet 14 is adsorbed and fixed to the sliding member 7, so that the sliding sleeve 3 and the fixed sleeve 2 no longer move elastically, which is beneficial to improving the burr removal effect, so that the product processing quality is good, and avoids the traditional The tool handle with telescopic function cannot grind the hard burrs of the welding parts properly, resulting in unclean burr treatment, affecting the appearance of the product. Finally, the first dustproof sheet 12 and the second dustproof sheet 13 are set to block the waste chips produced by grinding outside the slide groove 10, avoiding the waste chips from entering the slide groove 10 and being adsorbed and accumulated by the electromagnet 14, avoiding affecting the sliding efficiency of the sliding member 7, and avoiding the waste chips from entering the contact area between the sliding member 7 and the pole surface 11, causing the subsequent sliding member 7 to drive the adsorbed waste chips to rub against the pole surface 11 during movement, thereby causing the end face of the sliding member 7 to be worn, thereby affecting the fit between the sliding member 7 and the pole surface 11, and reducing the adsorption strength of the subsequent electromagnet 14 with the sliding member 7 after it is started, affecting the processing efficiency and product processing quality (it should be noted that the specific model specifications of the electrical parts involved in this scheme need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail).
