Detailed Description
The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-6: the utility model provides a hexagon nut burnishing device, includes workstation 1, be equipped with electronic slip table 2, controller 3 and polishing mechanism on workstation 1, base 4 is installed to the portion of sliding of electronic slip table 2, install slew bearing 5 on the base 4, install carousel 6 on the slew bearing 5, carousel 6 is rotatory through slew bearing 5 base 4 relatively, ring gear 7 is installed to carousel 6 lower extreme, ring gear 7 and the coaxial setting of carousel 6, install step motor 8 on the base 4, step motor 8 output is installed and is engaged with straight-teeth gear 9 of being connected with ring gear 7, opening 10 has been located to carousel 6 center, vertically be fixed with on the base 4 and pass the year thing pole 11 of opening 10, be fixed with spacing ring 12 on carrying the thing pole 11, be equipped with fixture on the carousel 6, fixture includes slide rail 13, the, The structure of the sliding block 14 and the sliding rail 13 is shown in fig. 6, one end, far away from the opening 10, of the sliding block 14 is connected with the air cylinder 16, the air cylinder 16 is fixedly installed on the rotary table 6, the sliding block 14 is driven by the air cylinder 16 to move only along the track of the sliding rail 13, the sliding block 14 is vertically provided with the V-shaped clamping plate 15, and the two V-shaped clamping plates 15 are matched with and clamp the hexagon nut 17.
In order to improve the clamping effect of the V-shaped clamping plate 15 on the hexagonal nut 17, the included angle of the V-shaped position of the V-shaped clamping plate 15 is set to be 120 degrees, so that the V-shaped clamping plate 15 can be attached to the hexagonal nut 17 when clamping the hexagonal nut 17, and the contact area is increased.
The polishing mechanism comprises a vertical plate 18, a first mounting plate 19, a second mounting plate 20, a third mounting plate 21, a driving rotating wheel 22, a driven rotating wheel 23, a polishing belt 24 and a rotating motor 25, the vertical plate 18 is vertically and fixedly arranged on the workbench 1, the first mounting plate 19, the second mounting plate 20 and the third mounting plate 21 are sequentially and horizontally arranged on the vertical plate 18 from top to bottom, the lower ends of the driving runner 22 and the driven runner 23 are rotatably mounted on the third mounting plate 21, the upper ends of the driving runner 22 and the driven runner 23 are rotatably mounted on the second mounting plate 20, the polishing belt 24 is connected with the driving rotating wheel 22 and the driven rotating wheel 23 in a tensioning transmission way, the rotating motor 25 is arranged on the first mounting plate 19, the output end of the rotating motor 25 is connected with the driving rotating wheel 22, and the height of the polishing belt 24 is matched with the maximum height of the stacked hexagonal nuts 17 so as to uniformly polish the hexagonal nuts 17.
