[0002] In the modern industrial production system, welding and grinding, as the core processes of metal processing and manufacturing, directly determine the product quality and production efficiency with their technological levels. With the transformation of the manufacturing industry towards high-end and intelligent development, the limitations of traditional processing modes have become increasingly prominent.

[0003] Traditional welding and grinding operations usually adopt manual operation or use independent welding equipment and grinding equipment separately. When processing workpieces, the traditional welding and grinding operations have the following deficiencies:

[0004] (1) When performing full-surface processing on polyhedral workpieces, the operator needs to frequently manually rotate the workpiece, which is not only inefficient but also prone to problems such as welding misalignment and uneven grinding due to positioning deviation. Moreover, it is necessary for the staff to confirm that the welding and grinding on one side are completed before changing the surface, resulting in low efficiency.

[0005] (2) The high-temperature welding slag generated during welding will firmly adhere to the surface of the workpiece, and the metal chips generated during grinding are also often embedded in the workpiece texture, making it difficult to quickly remove.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The embodiments of the present invention provide three technical solutions, which specifically include the following embodiments:

[0034] Embodiment 1

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , a robot welding and grinding integrated machine, including a base 1. A processing table 2 is arranged above the base 1. The processing table 2 is fixed on one side of the side seat 13. A through hole 3 is formed through the top of the processing table 2. The setting of the through hole 3 reserves space for the setting of the intermittent rotation and stop mechanism 4. An intermittent rotation and stop mechanism 4 is arranged on the processing table 2. The intermittent rotation and stop mechanism 4 is used to drive the workpiece to perform intermittent rotation of 90 degrees and stop.

[0036] The intermittent rotation and stop mechanism 4 includes a vertical plate 41 fixed to the bottom of the processing table 2. On one side of the vertical plate 41, a fixed cylinder 42 is fixed. A rotating cylinder 43 is rotatably connected to the top wall of the fixed cylinder 42. The rotating shaft of the rotating cylinder 43 penetrates through the fixed cylinder 42 and extends to the outside of the fixed cylinder 42. A cross plate 44 is fixed on the rotating shaft of the rotating cylinder 43. A pressing cylinder 45 is slidably connected to the bottom of the fixed cylinder 42. A wave groove 46 is formed on the outer surface of the rotating cylinder 43. On both sides of the inner wall of the pressing cylinder 45, a convex column 47 is fixed. Both convex columns 47 slide in the wave groove 46. Each time the convex column 47 slides up and down in the wave groove 46 for a round trip, the rotating cylinder 43 can be driven to rotate 90 degrees. On both sides of the pressing cylinder 45, a limiting block 48 is fixed. On both sides of the inner wall of the fixed cylinder 42, a limiting groove 49 is formed. The size of the limiting block 48 is adapted to that of the limiting groove 49. The limiting block 48 slides in the limiting groove 49.

A first spring 410 is fixed between the top wall of the fixed cylinder 42 and the bottom wall of the pressing cylinder 45. The setting of the first spring 410 is used for the reset of the pressing cylinder 45.

[0042] Embodiment 2

[0043] Based on Embodiment 1, refer to Figure 7 As shown, a cyclic energy storage impact assembly 7 is further provided on the processing table 2. The cyclic energy storage impact assembly 7 is used to impact the surface of the workpiece to cause vibration, assisting in the shedding of welding slag and metal chips. The cyclic energy storage impact assembly 7 includes an L-shaped seat 71 fixed to the top of the processing table 2. A chute 72 is provided at the top of the L-shaped seat 71. A power storage plate 73 is slidably connected to the top of the L-shaped seat 71. A slider 74 is fixed to the bottom of the power storage plate 73.

[0044] The slider 74 slides in the chute 72. A plurality of impact rods 75 are fixed to one side of the power storage plate 73.

A side rod 78 is fixed to one side of the square plate 77. One end of the side rod 78 contacts and presses against one side of the power storage plate 73.

[0045] Through the setting of the cyclic energy storage impact assembly 7, when the intermittent rotation and stop mechanism 4 works, it can drive the energy storage impact assembly 7 to perform energy storage operation synchronously, so that the impact rods 75 are energized, and then impact on the surface of the workpiece, causing the workpiece to be impacted and vibrated, making the high-temperature welding slag and metal chips on the surface of the workpiece vibrate and loosen, facilitating the further treatment of the welding slag and metal chips, and improving the removal efficiency.

[0046] Embodiment 3

[0047] Based on Embodiment 2, refer to Figure 3 As shown, a rotary dust blowing mechanism 8 is provided on one side of the processing table 2. The rotary dust blowing mechanism 8 is used to blow away the welding slag and metal chips on the surface of the workpiece. The rotary dust blowing mechanism 8 includes a connecting plate 81 fixed to one side of the processing table 2. A rotating column 82 is rotatably connected to the top of the connecting plate 81. Four rotating plates 83 are fixed to the rotating column 82. One end of the side rod 78 contacts and presses against one side of the rotating plate 83. A vertical pipe 84 is fixed to the top end of the rotating column 82. A plurality of air guide pipes 85 are connected in a circumferential manner to the vertical pipe 84. An air inlet pipe 86 is connected to the top of the vertical pipe 84.

[0048] Through the setting of the rotary dust blowing mechanism 8, it is linked with the intermittent rotation and stop mechanism 4. When the intermittent rotation and stop mechanism 4 works, it can drive the vertical pipe and the air guide pipes 85 to rotate synchronously and intermittently by 90 degrees. By using the rotation of the air guide pipes 85, the blowing angle is changed, and then the loosened high-temperature welding slag and metal chips on the surface of the workpiece are blown away. By continuously changing the blowing angle, the dust blowing efficiency and effect are greatly improved.

[0049] Meanwhile, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0050] During operation, place the workpiece to be processed on the cross plate 44, press down on the workpiece, and the workpiece contacts and squeezes the inclined surfaces of the four wedge-shaped blocks 63, driving the four wedge-shaped blocks 63 to move away from each other, causing the horizontal pipe 64 to slide along the outer surface of the cross bar 65. At the same time, compress the second compression spring 66, and use the elastic force of the second compression spring 66 to clamp the workpiece. Further start the motor 53, and the motor 53 drives the drive rod 52 and the cam 54 to rotate. When the cam 54 intermittently squeezes the pressing cylinder 45 during rotation, when the pressing cylinder 45 is squeezed upward, it drives the two convex columns 47 to slide up and down reciprocally in the wave-shaped groove 46. At the same time, the limiting block 48 slides in the limiting groove 49. When the convex column 47 slides in the wave-shaped groove 46, the rotating cylinder 43 rotates. Each time the pressing cylinder 45 is pressed, it drives the rotating cylinder 43 to rotate 90 degrees, thereby driving the cross plate 44 and the workpiece to rotate intermittently by 90 degrees. Start the welding gun 29, and the welding gun 29 welds the surface of the workpiece. Start the grinding disc 17, and the grinding disc 17 grinds the surface of the workpiece. By starting the third cylinder 24, the third cylinder 24 drives the second sliding seat 22 to slide up and down along the second slide rail 21, thereby adjusting the welding height of the welding gun 29. By starting the second cylinder 19, the second cylinder 19 drives the first sliding seat 15 to slide horizontally along the first slide rail 14, thereby adjusting the grinding depth of the grinding disc 17. When the workpiece rotates 90 degrees, it synchronously drives the side rod 78 to rotate. When the side rod 78 rotates to one side of the energy storage plate 73, it squeezes one side of the energy storage plate 73, and the energy storage plate 73 squeezes the third compression spring 76, thereby causing the impact rod 75 to store energy. When the side rod 78 rotates away from the energy storage plate 73, the third compression spring 76 in the compressed state at this time resets, driving the impact rod 75 to impact the surface of the workpiece, causing the workpiece to vibrate, loosening the high-temperature welding slag and metal debris adhering to the surface of the workpiece. When the side rod 78 rotates, it drives the rotating plate 83 to rotate intermittently by 90 degrees synchronously, thereby driving the vertical pipe 84 and the air guide pipe 85 to rotate. Start the external blower, blow the air into the vertical pipe 84 through the air inlet pipe 86, and then discharge it from the air guide pipe 85. When the air guide pipe 85 rotates, the blowing angle can be adjusted, thereby more efficiently blowing away the welding slag loosened on the surface of the workpiece and the adhering metal debris.

[0051] The embodiments of the invention have been described in detail above, but the above content is only the preferred embodiment of the present invention and should not be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
