Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a surface polishing equipment for curved surface alloy accessories. Background Art

[0002] Alloy shafts are the most common components in the mechanical field. During the production process, their curved surfaces need to be polished to ensure that their surfaces are smooth and meet production needs. When polishing the alloy shaft, the staff needs to use a fixture to clamp it in place, drive the alloy shaft to rotate through a motor, and then drive the sponge wheel to rotate through another motor to achieve the polishing of the alloy shaft. The existing polishing equipment needs to use multiple motors during design, which makes the manufacturing cost of the entire equipment high.

[0039] like Figure 4 and Fig.13As shown, the alloy shaft support mechanism includes a movable carrier bar 5 and a matching gear 54. A downward pressure driving plate 51 is symmetrically fixed at both ends of the movable carrier bar 5. A linkage through hole 52 is opened on the downward pressure driving plate 51.

The threaded bearing rod 53 passes through the installation through hole 171 and the matching through hole 18, and a matching gear 54 is threadedly sleeved on the threaded bearing rod 53.

[0040] like Figure 1 and Fig.13 As shown, a mounting platform 55 is fixedly provided at the lower end of the mating gear 54, and a threaded through hole 56 is provided on the mounting platform 55, the threaded through hole 56 penetrates the mating gear 54, and a threaded bearing rod 53 is threadedly connected in the threaded through hole 56, a second bearing 57 is sleeved on the mounting platform 55, and the second bearing 57 is installed in the mounting through hole 171, a bearing base plate 58 is fixedly provided at the lower end of the threaded bearing rod 53, a mating channel 581 is provided on the bearing base plate 58, and a supporting vertical rod 582 is fixedly provided on the bearing base plate 58, the supporting vertical rod 582 is plugged into the movable plug hole 19, and a positioning bearing platform 583 is fixedly provided on the upper end of the supporting vertical rod 582, in addition, when the stabilizing plug plate 35 fixes the movable carrier strip 5, it is plugged into the mating channel 581.

[0041] like Figure 2 , Fig.11 and Fig.12 As shown, the shaft auxiliary fixing mechanism includes a moving rod 6 and a linkage carrier block 64. The moving rod 6 is inserted in the matching column cavity 40. One end of the moving rod 6 is fixedly provided with a moving plug plate 61, and the moving plug plate 61 is inserted in the top tightening sleeve 41. The other end is fixedly provided with a connecting carrier plate 62. The connecting carrier plate 62 is hinged with a matching rod 63.

[0042] When polishing the alloy shaft, it is positioned and placed on the positioning bearing platform 583, and then the hydraulic rod 15 is started to drive the bearing mounting plate 16 to move. As the bearing mounting plate 16 moves, the connecting plug 166 and the driving connecting groove 32 will drive the connecting bearing bar 3 to move in the direction of the supporting mounting frame 13. In this way, under the action of the connecting rod 36, the two movable bearing columns 4 will be driven to move toward each other, so that the top tightening sleeve 41 contacts the end of the alloy shaft, and then clamps and supports the alloy shaft from both ends.

In this way, under the action of the matching rack 167, the matching gear 54 will be driven to rotate, and then under the action of the thread, it will drive The movable carrier bar 5 moves downward, thereby causing the positioning bearing platform 583 to move downward and no longer contact the alloy shaft, thereby avoiding obstruction to the polishing work. As the movable carrier bar 5 moves downward, it will also drive the linkage carrier block 64 to move downward, and then, under the action of the matching rod 63, it will drive the movable rod 6 to move relative to the movable bearing column 4. Since the top tightening sleeve 41 is in contact with the end face of the alloy shaft at this time, that is, the sleeve opening of the top tightening sleeve 41 is in a sealed state, as the movable rod 6 moves, a negative pressure will be formed in the top tightening sleeve 41 under the action of the movable plug plate 61, further strengthening the fixation of the alloy shaft and fully ensuring the stability of the alloy shaft during the polishing process. At this time, the hollow sponge wheel 26 is also sleeved on the alloy shaft. Starting the motor 162 can drive the hollow sponge wheel 26 to rotate. As the hydraulic rod 15 drives the hollow sponge wheel 26 to move, the polishing work of the alloy shaft can be realized, and the polishing work of the alloy shaft can be completed with only one clamping, which is very convenient.
