DETAILED DESCRIPTION

[0021] See also Figure 1-5 The utility model provides a welding auxiliary device for the production of acoustic mold frames, including a work table 1, wherein two symmetrically distributed fixing seats 2 are fixed at the middle position of the top surface of the work table 1, and an L-shaped positioning seat 4 is provided on the side where the two fixing seats 2 are close to each other, and a clamping plate 22 is provided on the side where the fixing seats 2 are close to each other. A symmetrically distributed hydraulic cylinder 3 is fixed on the side where the fixing seats 2 are away from each other, and a fixing ring 7 is fixed on the surface of the positioning seats 4 on the side away from each other. A ring groove 8 is provided on the surface of the fixing ring 7, and a connecting block 9 is inserted into the inner sliding part of the ring groove 8. One side of the connecting block 9 passes through the ring groove 8 and extends out of the outside of the fixing ring 7. The output end of the hydraulic cylinder 3 passes through the adjacent fixing seat 2 and is fixed to the surface of the adjacent connecting block 9. A movable shaft 5 is rotatably connected through the middle position of the fixing seat 2, and one side of the movable shaft 5 is fixed to the middle position of the surface of one side of the adjacent positioning seat 4. The outer peripheral surface of the output end of the hydraulic cylinder 3 The fixed sleeve is provided with a fixing bar 10, and the surface of the fixing bar 10 is rotatably connected to the rotating rod 11. The two fixing seats 2 are located at the bottom of the positioning seat 4 and are rotatably connected to the rotating rod 6. The outer peripheral surface of the rotating rod 11 is fixedly sleeved with a first gear 12, and the outer peripheral surface of the movable shaft 5 and the two sides of the outer peripheral surface of the rotating rod 6 are sleeved with second gears 13. The two second gears 13 are meshed with the first gears 12 at adjacent positions. The rotating rod 6 is rotated, so that the positioning seat 4 can be rotated under the meshing action between one of the second gears 13 and the first gear 12 and the first gear 12 and the other second gear 13, thereby driving the mold frame clamped by the two positioning seats 4 to rotate. In this way, the output end of the hydraulic cylinder 3 is controlled to make the two positioning seats 4 move in a direction close to each other to fix mold frames of different lengths. After that, the fixed mold frame can be rotated, thereby facilitating multi-directional welding operations.

[0022] Further as Figure 1 、 Figure 2 and Figure 4As shown, it is worth mentioning that symmetrically distributed interference pieces 14 are fixed at the upper and lower ends of the surfaces of both sides of the second gear 13. The surfaces of the interference pieces 14 interfere with the surfaces of both sides of the adjacent first gear 12. The movable shaft 5 and the upper and lower ends of the rotating rod 6 are provided with grooves 15. A limit block 16 is inserted into the inner circumference of the adjacent second gear 13 for sliding. One end of the limit block 16 is fixed to the inner circumference of the adjacent second gear 13. When the interference pieces 14 are provided at the upper and lower ends of both sides of the second gear 13, the fixed bar 10 can be driven to move in the horizontal direction at the output end of the hydraulic cylinder 3, thereby driving the first gear 12 to move in the horizontal direction. Under the interference of the interference piece 14, the two second gears 13 can move with the first gear 12. Due to the setting of the limit block 16 and the limit block 16, when the rotating rod 6 rotates, one of the second gears 13 can be rotated under the interference of the groove 15 and the adjacent position limit block 16, so that the first gear 12 can be rotated under the meshing action between the second gear 13 and the adjacent position first gear 12, so that the movable shaft 5 can be rotated under the meshing action between the first gear 12 and the other second gear 13 and the interference action of another group of grooves 15 and the limit block 16.

[0023] Further as Figure 1 As shown, it is worth mentioning that the rotating rod 6 is fixedly sleeved with a third gear 17 at the position at the bottom of the adjacent hydraulic cylinder 3, and a rack 21 is meshed at the bottom of the third gear 17. A rod groove 18 is opened at the top of the work table 1 at the bottom of the rack 21. The inside of the rod groove 18 is rotatably connected to a first threaded rod 19. One end of the first threaded rod 19 passes through the work table 1 and extends out of the outside of the work table 1. The outer circumference of the first threaded rod 19 located in the inner part of the rod groove 18 is threadedly connected to a first threaded sleeve 20. The top of the first threaded sleeve 20 is fixed to the surface of the bottom of the rack 21. By rotating the first threaded rod 19, the inner cavity of the first threaded rod 19 can play a role of resisting and limiting the first threaded sleeve 20, so that the rack 21 can move in the horizontal direction under the cooperation between the internal thread structure of the inner wall of the first threaded sleeve 20 and the external thread structure of the outer circumference of the first threaded rod 19, so that the rotating rod 6 can rotate under the meshing action between the rack 21 and the third gear 17.

[0024] Further as Figure 5As shown, it is worth mentioning that there are two openings 23 on the inner surface of the positioning seat 4, and one of the openings 23 is internally rotatably connected to a second threaded rod 24, one end of the second threaded rod 24 passes through the positioning seat 4 and extends to the position of one end of the positioning seat 4, and the outer peripheral surface of the second threaded rod 24 is threadedly connected to a second threaded sleeve 25, and one side of the second threaded sleeve 25 is fixed to the surface of the adjacent clamping plate 22. When the second threaded rod 24 is rotated, the opening 23 can play a role of resisting and limiting the second threaded sleeve 25 in the adjacent position, so that the clamping plate 22 can move in the vertical direction under the cooperation between the internal thread structure of the inner wall of the second threaded sleeve 25 and the external thread structure of the outer peripheral surface of the second threaded rod 24, so that the mold frame can be further clamped under the clamping action of the clamping plate 22 and the positioning seat 4.

[0025] This solution has the following working process: in actual use, when the user needs to fix the mold frame, first, by controlling the output end of the hydraulic cylinder 3, the distance between the two positioning seats 4 can be adjusted so that the positioning seat 4 can clamp and fix the mold frame placed in the middle position of the two positioning seats 4; then, when the second threaded rod 24 is rotated, the opening 23 can play a role of resisting and limiting the second threaded sleeve 25 at the adjacent position, so that the splint 22 can move in the vertical direction under the cooperation between the internal thread structure of the inner wall of the second threaded sleeve 25 and the external thread structure of the outer peripheral surface of the second threaded rod 24, so that the splint 22 can move in the vertical direction, so that the splint 22 and The mold frame can be further clamped under the clamping action of the positioning seat 4. When the distance between the two positioning seats 4 changes, the fixed bar 10 can be driven by the output end of the hydraulic cylinder 3 to move in the horizontal direction, thereby driving the first gear 12 to move in the horizontal direction. The two second gears 13 can move with the first gear 12 under the interference action of the interference piece 14, so that the movement trajectory of the second gear 13 can be limited under the interference action of the limit block 16 fixed on the inner wall of the second gear 13 and the groove 15. When the angle of the fixed mold frame needs to be adjusted, the first gear 12 can be moved by rotating the first gear 12. The threaded rod 19, since the inner cavity of the first threaded rod 19 can play a role of resisting and limiting the first threaded sleeve 20, the rack 21 can move in the horizontal direction under the cooperation between the internal thread structure of the inner wall of the first threaded sleeve 20 and the external thread structure of the outer peripheral surface of the first threaded rod 19, so that the rotating rod 6 can rotate under the meshing action between the rack 21 and the third gear 17, so that the second gear 13 at the adjacent position can be rotated under the interference between one set of limit blocks 16 and the adjacent position groove 15, so that the rotation can be made under the meshing action between the second gear 13 and the first gear 12. The rod 11 can rotate, so that the movable shaft 5 can rotate under the meshing action between the first gear 12 and another second gear 13 and the interference action of another set of grooves 15 and the limit block 16, thereby driving the positioning seat 4 and the fixed mold frame to rotate to achieve angle change. During this process, the rotation of the positioning seat 4 will cause the fixing ring 7 to rotate and the connecting block 9 is still located in the inner cavity position of the ring groove 8 during this process, so that when the output end of the hydraulic cylinder 3 extends again, it can still drive the distance between the positioning seats 4 to change, thereby facilitating the angle change of the fixed mold frame after the mold frame is fixed.

[0026] According to the above working process, it can be known that: by rotating the rotating rod 6, the positioning seat 4 can be rotated under the meshing action between one of the second gears 13 and the first gear 12 and the first gear 12 and the other second gear 13, thereby driving the mold frame clamped by the two positioning seats 4 to rotate. In this way, the output end of the hydraulic cylinder 3 is controlled to make the two positioning seats 4 move toward each other to fix mold frames of different lengths. After that, the fixed mold frames can be rotated, which facilitates multi-directional welding operations, thereby improving the scope of application of the device. By rotating the second threaded rod 24, the distance between the clamping plate 22 and the bottom of the inner surface of the adjacent positioning seat 4 can be adjusted, so that the mold frame clamped by the two positioning seats 4 can be further clamped and fixed from the upper and lower ends, thereby improving the stability of the mold frame fixation, thereby improving the practicality of the device.

[0027] Further as Figure 5 As shown, it is worth mentioning that a limiting rod 26 is fixed inside the other opening 23, and a limiting sleeve 27 is provided on the sliding sleeve on the outer peripheral surface of the limiting rod 26. One side of the limiting sleeve 27 is fixed to the surface of the adjacent position clamp 22. Since the limiting sleeve 27 can only slide along the outer peripheral surface of the limiting rod 26 in the inner cavity of the adjacent position opening 23, it can limit the movement trajectory of the clamp 22, thereby ensuring the clamping effect of the clamp 22.

[0028] In summary: by rotating the rotating rod 6, the positioning seat 4 can be rotated under the meshing action between one of the second gears 13 and the first gear 12 and the first gear 12 and the other second gear 13, thereby driving the mold frame clamped by the two positioning seats 4 to rotate. In this way, after the output end of the hydraulic cylinder 3 is controlled to move the two positioning seats 4 toward each other and fix the mold frames of different lengths, the fixed mold frames can be rotated, thereby facilitating multi-directional welding operations, thereby improving the scope of application of the device. By rotating the second threaded rod 24, the distance between the splint 22 and the bottom of the inner surface of the adjacent position positioning seat 4 can be adjusted, so that the mold frame clamped by the two positioning seats 4 can be further clamped and fixed from the upper and lower ends, thereby improving the stability of the mold frame fixation, thereby improving the practicality of the device. Since the limit sleeve 27 can only slide along the outer peripheral surface of the limit rod 26 in the inner cavity of the adjacent position opening 23, it can limit the movement trajectory of the splint 22, thereby ensuring the clamping effect of the splint 22.

[0029] The hydraulic cylinder 3 can be purchased on the market. The hydraulic cylinder 3 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
