Description

Technical Field

[0001] The utility model belongs to the field of nut surface sandblasting processing devices, in particular to a nut surface sandblasting processing device. Background Art

[0002] A nut is a mechanical component with an internal thread that is used in conjunction with a bolt or a screw to fasten two or more parts. It has an internal threaded hole in the center that matches the bolt or screw. There may also be some flat surfaces or notches on the surface or side of the nut for operation with a wrench or other tools to facilitate tightening or loosening the nut. When the nut needs to be surface treated by painting, electroplating, phosphating, etc., sandblasting can remove oil stains and impurities on the surface of the nut, making the surface of the nut rough and porous, thereby increasing the adhesion between the coating and the surface of the nut.

[0003] At present, when sandblasting nuts, in order to ensure the stability of the nuts during the sandblasting process, two adjustable clamps are usually set on the top of the sandblasting equipment, and the nuts are placed between the two clamps. The nuts are fixed by adjusting the distance between the two clamps, thereby preventing the nuts from shifting or shaking during the sandblasting process. However, after the nuts are fixed by the clamps, there will be some hard-to-reach dead angles or uneven sandblasting areas, requiring the staff to frequently adjust the position of the nuts, which increases the work intensity of the staff and reduces the overall work efficiency.

In the process of sandblasting the nut, the motor 12 is started, and the bevel gear 2 6 is driven to rotate by the motor 12. Because the bevel gear 1 5 is meshed with the bevel gear 2 6, and the bevel gear 1 5 is fixedly sleeved on the outside of the connecting column 4, when the bevel gear 2 6 rotates, the bevel gear 1 5 and the connecting column 4 are driven to rotate synchronously, and one of the fixed plates 13 is driven to rotate under the rotation of the connecting column 4, and the nut is driven to flip, and because the side of the fixed plate 13 away from the connecting column 4 is fixedly connected with one end of the fixed sleeve column 11, and the output end of the telescopic cylinder 10 is rotatably connected with the fixed sleeve column 11, in the process of flipping the nut, the friction between the nut and the movable plate 15 can drive the movable plate 15 and the fixed plate 13 to rotate, so that the fixed sleeve column 11 on one side of the fixed plate 13 rotates along the central axis of the output end of the telescopic cylinder 10, thereby completing the flipping of the nut;

[0026] A propulsion assembly 9 is provided on the side of the clamping structure 3 away from the connecting column 4. The propulsion assembly 9 includes a telescopic cylinder 10 and a fixed sleeve column 11. One end of the telescopic cylinder 10 is fixedly connected to one side of the inside of the sandblasting equipment. The output end of the telescopic cylinder 10 is located inside the fixed sleeve column 11. The output end of the telescopic cylinder 10 is rotatably connected to the fixed sleeve column 11. One end of the fixed sleeve column 11 away from the telescopic cylinder 10 is fixedly connected to the side of the clamping structure 3 away from the connecting column 4.

[0027] The clamping structure 3 is composed of two clamping components with the same structure, and the clamping components include a fixed plate 13, a connecting plate 14, a connecting piece and two movable plates 15. One side of the fixed plate 13 is fixedly connected to one end of the connecting column 4, and one side of the connecting plate 14 is connected to the side of the fixed plate 13 away from the connecting column 4 through an elastic member. Both ends of the connecting plate 14 are provided with grooves 16 for installing the connecting piece, and the bottom end of the connecting piece is fixedly connected to the bottom end of the inner side of the groove 16. One end of the two movable plates 15 is provided with a sleeve 17, and the sleeve 17 is movably sleeved on the outside of the connecting piece. One side of the two movable plates 15 is connected to the side of the fixed plate 13 away from the connecting column 4 through a spring 18 respectively, and the side of the movable plate 15 away from the spring 18 is inclined. The elastic member is a spring 2 19, one end of the spring 2 19 is fixedly connected to the side of the fixed plate 13 away from the connecting column 4, and the other end of the spring 2 19 is fixedly connected to the side of the connecting plate 14 close to the fixed plate 13, and the connecting piece is a pillar 20. The bottom end of the pillar 20 is fixedly connected to the bottom end of the inner side of the groove 16, and the sleeve 17 is movably sleeved on the outside of the pillar 20. The telescopic cylinder 10 is started, and one of the fixed plates 13 is pushed to move in the direction of the other fixed plate 13 by the telescopic cylinder 10, so that the outer side of the movable plate 15 set on the adjacent side of the two fixed plates 13 fits with the outer side of the nut, thereby limiting the nut. Since most nuts are polygonal, and the movable plate 15 and the connecting plate 14 are respectively connected to one side of the fixed plate 13 by spring 18 and spring 2 19, when the vertex of the nut squeezes the connecting plate 14, the connecting plate 14 will move in the direction of the fixed plate 13 and squeeze the spring 2 19. Because the movement of the connecting plate 14, the position of the pillar 20 will change, and then the sleeve 17 will rotate on the outside of the pillar 20, thereby driving the movable plate 15 to rotate slightly, so that the side of the movable plate 15 fits with the surface of the nut, thereby enhancing the limiting effect of the nut.

[0028] Working principle:

[0029] When the nut needs to be sandblasted, the nut is placed between the two fixed plates 13 inside the processing table 1, and the telescopic cylinder 10 is started. One of the fixed plates 13 is pushed to move toward the other fixed plate 13 by the telescopic cylinder 10, so that the outer side of the movable plate 15 set on the adjacent side of the two fixed plates 13 fits with the outer side of the nut, thereby limiting the nut. Since most nuts are polygonal, and the movable plate 15 and the connecting plate 14 are respectively connected to one side of the fixed plate 13 by spring 18 and spring 2 19, when the vertex of the nut presses the connecting plate 14, the connecting plate 14 will move toward the fixed plate 13 and press the spring 2 19. Because the movement of the connecting plate 14 will change the position of the pillar 20, the sleeve 17 will rotate on the outside of the pillar 20, thereby driving the movable plate 15 to rotate slightly, so that the side of the movable plate 15 fits with the surface of the nut, thereby enhancing the limiting effect of the nut.

[0030] It should be noted that the side of the movable plate 15 does not need to be completely in contact with the surface of the nut. For irregular nuts, the movable plate 15 can increase the contact area therebetween, thereby enhancing the limiting effect, and it does not need to be completely in contact with the nut. At the same time, the spring 18 connected to one side of the movable plate 15 can limit and reset the movable plate 15, preventing the movable plate 15 from excessive movement and also driving the movable plate 15 to reset after the nut is removed.

[0031] During the sandblasting process of the nut, the motor 12 is started, and the bevel gear 2 6 is driven to rotate by the motor 12. Because the bevel gear 1 5 is meshed with the bevel gear 2 6, and the bevel gear 1 5 is fixedly sleeved on the outside of the connecting column 4, when the bevel gear 2 6 rotates, the bevel gear 1 5 and the connecting column 4 are driven to rotate synchronously, and the rotation of the connecting column 4 drives one of the fixed plates 13 to rotate, and thereby drives the nut to flip, and because the side of the fixed plate 13 away from the connecting column 4 is fixedly connected to one end of the fixed sleeve column 11, and the output end of the telescopic cylinder 10 is rotationally connected to the fixed sleeve column 11, during the flipping process of the nut, the friction between the nut and the movable plate 15 can drive the movable plate 15 and the fixed plate 13 to rotate, so that the fixed sleeve column 11 on one side of the fixed plate 13 rotates along the central axis of the output end of the telescopic cylinder 10, thereby completing the flipping of the nut.
