[0027] like Figure 4 As shown, a sliding seat 20 is provided at one end of the grinding seat 21 , and the sliding seat 20 is connected to an end plate 28 provided at one end of the mounting seat 29 through a first spring 19 , and one end of a limiting rod 30 provided at one end of the end plate 28 contacts one end of the mounting seat 21 .

[0036] The specific usage and function of this embodiment are as follows:

[0037] The grinding assembly provided in the present invention can grind the inside and outside of the weld of the cylindrical sheet metal part at the same time, thereby improving the reliability of the weld of the cylindrical sheet metal part. Before using the grinding assembly, the cylindrical sheet metal part needs to be clamped using the positioning assembly. At this time, the telescopic rod 3 is first driven to extend, so that the center of the fixed frame 13 set at the top of the telescopic rod 3 and the axis of the cylindrical sheet metal part are moved to the same straight line, and then the third motor 8 is driven to rotate the screw 9 on the third motor 8 to drive the telescopic rod 3 and the moving frame 24 set thereon to move along the axis of the screw 9, so that the friction roller 15 moves to both sides of the side wall of the cylindrical sheet metal part, and then one of the hydraulic rods 18 is driven to extend and retract until a pair of clamping frames 17 slidingly connected on the clamping frame 17 move to a position equal to the side wall of the cylindrical sheet metal part. At this time, the first motor 27 set on the clamping frame 17 is started, so that the gear 23 set at the output shaft end of the first motor 27 drives the racks 22 set on both sides thereof to move toward each other. At this time, the grinding seat 21 where the rack 22 is located will gradually approach until the two pairs of friction rollers set on the clamping seat The side walls of the wiping roller 15 are respectively squeezed and contacted with the inner and outer walls of the cylindrical sheet metal part. At this time, another hydraulic rod 18 is driven to extend and retract. According to the data recorded by the comparison component, the movable frame 24 connected to the grinding assembly is moved to a suitable position. Similarly, the grinding wheel 31 in the grinding assembly clamps the side wall of the sheet metal part. At this time, the second motor 16 arranged on the clamping seat can be started to make the friction roller 15 drive the cylindrical sheet metal part to rotate until one end of the limiting rod 30 no longer contacts the inner wall of the sliding seat 20. At this time, it indicates that the grinding wheel 31 moves to both sides of the weld. At this time, the second motor 16 arranged on the mounting seat 29 is started, so that the grinding wheel 31 connected to the output shaft end of the second motor 16 can grind the weld surface until one end of the limiting rod 30 contacts the inner wall of the sliding seat 20 again. At this time, the third motor 8 is driven to move the fixed frame 13 along the axial direction of the cylindrical sheet metal part until the surface of the complete weld is processed. Finally, the telescopic rod 3 and the components connected thereto are reset. After the parts are cooled, the sheet metal parts on the bracket 2 can be pulled out in the direction away from the fixed frame 13.

[0038] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here.
