[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a hardware shaft docking device includes a base plate 1, a first structural plate 2 and a side plate 3, the top of the base plate 1 is fixed with a side plate 3 by bolts, the inside of the side plate 3 is provided with an adjusting screw 10 through a threaded groove, one end of the adjusting screw 10 is mounted with a second structural plate 11 through a bearing, one side of the second structural plate 11 is provided with a scraper 12 through a mounting seat, one side of the side plate 3 is fixed with a ventilation box 15 by bolts, an exhaust fan 17 is installed inside the ventilation box 15 through a mounting frame, the first structural plate 2 is welded to one end of the top of the base plate 1, the inside of the first structural plate 2 is provided with a screw rod 7 through a threaded groove, one end of the screw rod 7 is provided with a second three-jaw chuck 6 through a bearing, the other end of the top of the base plate 1 is provided with a driving motor 4 through a mounting frame, and one side of the output shaft of the driving motor 4 is fixed with the first three-jaw chuck 5 through a flat key.

[0021] Among them, Figure 3 and Figure 4 As shown, a through hole 16 is opened between the ventilation box 15 and the side plate 3, and a dustproof net 18 is fixed by bolts on the side of the ventilation box 15 away from the side plate 3. The opening of the through hole 16 enables the exhaust fan 17 to operate and draw the gas between the axial workpieces.

[0022] Among them, Figure 3 As shown, a second auxiliary rod 13 is connected to one side of the second structural plate 11 through a threaded groove. The second auxiliary rod 13 passes through the side plate 3. The arrangement of the second auxiliary rod 13 can improve the structural stability of the first structural plate 11 without affecting its movement.

[0023] Among them, Figure 1 As shown, a discharge chute 14 is provided on the top of the bottom plate 1 , and the discharge chute 14 is provided to facilitate the scraped welding blocks and waste materials to flow out from the bottom plate 1 .

[0024] Among them, Figure 2 As shown, two ends of one side of the second three-jaw chuck 6 are connected with a first auxiliary rod 8 through a threaded groove. The first auxiliary rod 8 passes through the first structural plate 2. The first auxiliary rod 8 can improve the structural stability of the second three-jaw chuck 6 without affecting its movement.

[0025] Among them, Figure 2 As shown, the end of the screw rod 7 away from the second three-jaw chuck 6 is fixed with a rocker 9 through a flat key. The setting of the rocker 9 makes it convenient for personnel to rotate the screw rod 7.

[0026] It should be noted that the utility model is a hardware shaft docking device. When working, the personnel use the power cord to connect the device to an external power supply, clamp the two axial workpieces on the first three-jaw chuck 5 and the second three-jaw chuck 6 respectively, hold the rocker 9 to rotate the screw rod 7, and push the second three-jaw chuck 6 to move toward the first three-jaw chuck 5, so that the ends of the two axial workpieces are in contact, and the first auxiliary rod 8 can improve its structural stability without affecting the movement of the second three-jaw chuck 6. Turn on the drive motor 4 to drive the first three-jaw chuck 5 and the axial workpiece clamped by it to rotate at a high speed. When it rotates, the end of the axial workpiece generates friction with the other axial workpiece, thereby generating heat. As the axial workpiece rotates at a high speed, the temperature of its end continues to rise until the temperature rises To a temperature range close to but generally lower than the melting point, when the ends of the two axial workpieces rise to a temperature range close to but generally lower than the melting point, the screw rod 7 is rotated to push the axial workpiece clamped by the second three-jaw chuck 6 to move, so that the two ends of the axial workpieces are firmly pressed together for welding. After the two ends of the axial workpieces are welded together, the exhaust fan 17 is turned on to draw the gas around the two axial workpieces through a plurality of through holes 16 to accelerate the flow of gas and cool down the welding point. The personnel rotate the adjusting screw 10 to push the second structural plate 11 to move, so that the scraper 12 on one side of the second structural plate 11 is against the welding point of the two axial workpieces. When the two axial workpieces rotate at high speed, the scraper 12 scrapes off the welding blocks, waste materials, etc. at the welding point.
