Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy pipe bending and grinding technology, specifically to an adaptive sandblasting and grinding equipment for alloy pipe bending. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN109605228A, published on April 12, 2019, which discloses a continuous aluminum alloy tube sandblasting device, belonging to the technical field of sandblasting devices. The device comprises a feeding rack, a first conveyor, a sandblasting machine, and a second conveyor arranged sequentially along a straight line. The sandblasting machine uses an annular sandblasting ring, utilizing the sandblasting channel formed in the middle of the ring to achieve uniform sandblasting of a single aluminum alloy tube. This enables linear transport and sandblasting of the aluminum alloy tube. The aluminum alloy tube is placed in the guide trough on the corresponding feeding rack, and then transported by the first drive roller in the first conveyor, passing through the sandblasting machine for sandblasting. After sandblasting, the aluminum alloy tube is then conveyed out by the second drive roller. This conveying process continuously replenishes the aluminum alloy tube, ensuring continuous feeding and sandblasting, significantly improving the sandblasting efficiency of the aluminum alloy tube and showing promising application prospects.

[0003] However, due to the curved structure of aluminum alloy bends, grinding on both sides needs to be done in steps. Although the device can achieve continuous sandblasting of straight pipes, it cannot adapt to their curved shape. Bends still need to be ground manually, which is inefficient and of unstable quality. It cannot fix bends of different diameters and cannot take into account the complex curved surface and size diversity of bends. Utility Model Content

Through the motion adjustment mechanism 6, the left and right motion adjustment plus the front and back motion adjustment, combined with the rotation adjustment driven by the second motor 7, can enable the sandblasting and grinding device to perform corresponding motion processing on the bent pipe.

[0019] The motion adjustment mechanism 6 includes two vertical guide rods 61 and two horizontal guide rods 62 fixedly connected to the inner wall of the support frame 5. Sliding blocks 63 are slidably connected to the surfaces of the two vertical guide rods 61 and the two horizontal guide rods 62. A first motor 64 is fixedly connected to both the front sliding block 63 and the left sliding block 63. A horizontal screw 65 is fixedly connected to the output end of the left first motor 64, and a vertical screw 66 is fixedly connected to the output end of the front first motor 64. A moving block 67 is threaded between the surfaces of the horizontal screw 65 and the vertical screw 66.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] The working principle of this utility model is as follows: First, place one end of the bent pipe in the middle of the three clamping blocks 49. Then, start the electric telescopic rod 44, causing its output shaft to retract and drive the rack 45 at the output end to move downward. When the rack 45 moves, it drives the first gear 410, which rotates on the front of the fixed seat 3 via the rotating shaft 43. When the rotating shaft 43 rotates, it drives the rotating disk 411 on its surface to rotate synchronously. When the rotating disk 411 rotates, it squeezes and drives the three connecting shafts 47 through the three transmission holes 412. The three connecting shafts 47 drive the three sliding sleeves 46 to move inward on the surface of the three limiting strips 42. When the three sliding sleeves 46 move, they drive the three clamping blocks 49 to move closer to each other through the three connecting strips 48, so that the three clamping blocks 49 simultaneously clamp the bent pipe and fix it. Then, start the automatic sandblasting and polishing device body 2 to perform automatic sandblasting and polishing operation. Then, start the second motor 7, which drives the second gear through the output shaft. When wheel 9 rotates, the second gear 9 rotates, driving the third gear 10. The third gear 10 rotates on the top of the moving block 67 via the rotating shaft 8. When the rotating shaft 8 rotates, it drives the automatic sandblasting and polishing device body 2 to rotate synchronously. At the same time, the first motor 64 on the left is started, driving the horizontal screw 65 at the output end to rotate. When the horizontal screw 65 rotates, it drives the moving block 67. The moving block 67 drives the first motor 64 at the front and the vertical screw 66 to move to the left via two sliding blocks 63 on the surface of two horizontal guide rods 62, thereby adjusting the position of the moving block 67 and all its top structures to the left. Then, the first motor 64 at the front is started again, driving the vertical screw 66 at the output end to rotate. When the vertical screw 66 rotates, it drives the moving block 67, driving the first motor 64 on the left and the horizontal screw 65 to move backward via two sliding blocks 63 on the surface of two vertical guide rods 61, thereby adjusting the position of the moving block 67 and all its top structures backward.
