[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] like Figure 1 As shown, a single-sided surface treatment device for welded joints of sheet metal parts includes an axle beam 1, a swing arm 2, and a grinding mechanism 3. The grinding mechanism 3 is mounted on the axle beam 1 via the swing arm 2. The grinding mechanism 3 includes a front grinding mechanism 31 and a rear grinding mechanism 32 in a grinding direction 4. The front grinding mechanism 31 and the rear grinding mechanism 32 are located at the same horizontal height, forming a dual grinding mechanism for performing front and rear grinding on the welds of the sheet metal part 7. The dual front and rear grinding structure design of the present invention allows simultaneous front and rear grinding of different welds of the sheet metal part 7 in the same direction. Compared with a single grinding method in which different welds are polished sequentially, the efficiency of single-sided polishing of the sheet metal part is greatly improved.
[0019] More specifically, Figure 1 and Figure 2 As shown, the front grinding mechanism 31 comprises a front drive unit 31.1 drivingly connected to a front grinding wheel 31.2; the rear grinding mechanism 32 comprises a rear drive unit 32.1 drivingly connected to a rear grinding wheel 32.2. The front grinding wheel 31.2 and the rear grinding wheel 32.2 are located in the grinding direction 4, and the front and rear heights are kept consistent. The front and rear drive units 31.1 and 32.1 each utilize a grinding motor.
[0020] It should be noted that, in the technical solution of the front and rear double grinding of the present invention, the front grinding wheel 31.2 and the rear grinding wheel 32.2 are equivalent to providing two fulcrums, which improves the stability of the equipment during the grinding process, thereby improving the grinding quality.
[0021] In the present invention, the abrasive grits of the front grinding wheel 31.2 and the rear grinding wheel 32.2 can be the same or different depending on the operation requirements, as follows:
[0022] Abrasive grit selection 1: The abrasive grit of the front grinding wheel 31.2 and the rear grinding wheel 32.2 are the same, which can improve the grinding efficiency.
[0023] Abrasive grit selection 2: The abrasive grit of the front grinding wheel 31.2 is larger than that of the rear grinding wheel 32.2, which can achieve different grinding degrees at the front and rear, gradually improve the grinding fineness, and also improve the grinding efficiency. It should be noted that the difference in abrasive grit selection between the two grinding wheels should not be too large, so as not to affect the grinding quality.
[0024] like Figure 2 and Figure 3 As shown, the swing arm 2 is sleeved on the axle beam 1, so that the grinding mechanism 3 can swing in the circumferential direction around the axle beam 1 to adjust the wheelbase between the front grinding wheel 31.2 and the rear grinding wheel 32.2, so that the corresponding grinding distance can be adapted according to the two welds on the sheet metal. After the distance is adjusted, it needs to be fixed. Therefore, a locking mechanism 5 is also provided between the swing arm 2 and the axle beam 1 of the present invention, and the swing arm 2 can be fixed relative to the axle beam 1 through the locking mechanism 5.
[0025] More specifically, Figure 2 As shown, the swing arm 2 includes a first swing arm 21 corresponding to the front grinding mechanism 31 and a second swing arm 21 corresponding to the rear grinding mechanism 32; the locking mechanism 5 includes a first locking mechanism 51 corresponding to the first swing arm 21 and a second locking mechanism 52 corresponding to the second swing arm 21. The locking mechanism 5 is a locking bolt movably connected to the swing arm 2. The axle beam 1 has a circumferential expansion block 8 located between the first and second swing arms 21. The two axial ends of the circumferential expansion block 8 are respectively provided with a plurality of positioning threaded blind holes 9 arranged in a circumferential arc array. By screwing the locking bolts into the corresponding positioning threaded blind holes 9, the corresponding swing arm 2 can be fixed.
[0026] like Figure 1 or Figure 2 As shown, handles 6 are provided at both ends of the axle beam 1 to facilitate the staff to operate the equipment.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
