Description

Technical Field

[0001] This utility model belongs to the field of positioning equipment technology, and in particular relates to an automatic positioning and adjustment device for welding material feeding. Background Technology

[0002] In modern automated welding production, precise workpiece positioning and stable feeding are key to ensuring welding quality. Especially in complex workpieces or mass production, traditional positioning methods can easily lead to workpiece displacement and unstable clamping, which in turn affects welding accuracy and product consistency.

[0003] Currently, although some automatic positioning devices on the market have improved positioning efficiency to a certain extent, they still have the following technical defects: most devices use positioning adjustment in a single direction, which makes it difficult to adapt to the positioning needs of workpieces of different sizes or shapes, resulting in poor versatility. Traditional mechanical positioning relies on manual adjustment and cannot achieve fine-tuning, leading to insufficient repeatability accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that positioning adjustment using a single direction is difficult to adapt to the positioning needs of workpieces of different sizes or shapes, has poor versatility, and traditional mechanical positioning relies on manual adjustment and cannot achieve fine-tuning.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic positioning and adjustment device for welding material feeding, comprising a square frame, wherein a placement plate is rotatably connected to the top of the square frame, and further comprising...

[0006] A positioning component, mounted on a square frame, includes an electric push rod fixedly installed at the bottom of the square frame. A connecting plate is fixedly connected to the free end of the electric push rod. The top of the square frame has symmetrically distributed stroke holes. A guide rod is fixedly connected between the inner walls of the stroke holes. A horizontal slider slides on the guide rod. A connecting rod is hinged between the bottom of the slider and the connecting plate.

[0007] Furthermore, a horizontal cylinder is fixedly connected to the slider, one end of the cylinder is open and fixedly connected to a suction cup, a cylinder is fixedly installed on the inner wall of the cylinder, and a piston is fixedly connected to the free end of the cylinder.

[0008] Furthermore, an inner frame is fixedly connected to the top of the frame, and a vertical shaft is fixedly connected to the bottom wall of the placement plate, with its lower end vertically penetrating the inner frame and rotatably connected to it.

[0009] Furthermore, a servo motor is fixedly installed on the inner frame, a worm gear is fixedly connected to the output end of the servo motor, and a worm wheel that meshes with the worm gear is fixedly connected to the lower end of the vertical shaft.

[0010] Furthermore, the bottom of the frame is provided with a U-shaped support, and a hydraulic rod is fixedly installed on the top of the support. The free end of the hydraulic rod is fixedly connected to the bottom of the block.

[0011] Furthermore, limit blocks are fixedly connected to both the left and right side walls of the frame, and guide rails are fixedly connected to both sides of the inner wall of the support, with the limit blocks and guide rails being slidably connected.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] (1) The operator places the material to be processed on the placement plate stably. The servo motor can be started according to the processing requirements. The vertical shaft is driven to rotate through the worm gear transmission, which drives the placement plate and the material to achieve precise angle adjustment, so that the surface to be processed is accurately facing the suction cup position. This avoids the tedious operation of traditional manual adjustment and significantly improves processing efficiency and positioning accuracy.

[0014] (2) Control the electric push rod to retract and drive the connecting plate to move down. Through the linkage of the hinged connecting rod, the two sets of sliders slide synchronously towards each other along the guide rod. When the suction cup contacts the material surface, the cylinder starts to retract, driving the piston to form a negative pressure in the horizontal cylinder, realizing the double positioning and fixing of the material. This ensures the reliability of positioning and avoids the material damage that may be caused by traditional rigid clamping.

[0015] (3) The hydraulic rod can be controlled to extend and retract, driving the entire frame mechanism to rise and fall smoothly along the support guide rail. The cooperation between the limit block and the guide rail ensures the stability of the lifting process, so that the material can accurately reach the predetermined processing height position, which can meet the processing needs of different height specifications.

Detailed Implementation

[0023] like Figure 1-2 As shown, an automatic positioning and adjustment device for welding material feeding includes a frame 1, a placement plate 2 rotatably connected to the top of the frame 1, and a positioning component disposed on the frame 1.

[0024] like Figure 1-4 As shown, in order to facilitate the adjustment of the material placement direction, an inner frame 14 is fixedly connected to the top of the inner frame 1, and a vertical shaft 15 is fixedly connected to the bottom wall of the placement plate 2, with its lower end vertically penetrating the inner frame 14 and rotatably connected to it. A servo motor 16 is fixedly installed on the inner frame 14, and a worm gear 17 is fixedly connected to the output end of the servo motor 16. A worm wheel 18 that meshes with the worm gear 17 is fixedly connected to the lower end of the vertical shaft 15. The vertical shaft 15 is driven to rotate through the worm wheel 18 and the worm gear 17, thereby driving the placement plate 2 and the material to achieve precise angle adjustment. This avoids the tedious operation of traditional manual adjustment and significantly improves processing efficiency and positioning accuracy.

[0025] like Figure 1-5 As shown, to facilitate material positioning, the positioning assembly includes an electric push rod 3 fixedly installed at the bottom of the frame 1. A connecting plate 4 is fixedly connected to the free end of the electric push rod 3. The top of the frame 1 has symmetrically distributed stroke holes 5. A guide rod 6 is fixedly connected between the inner walls of the stroke holes 5. A horizontal slider 7 slides on the guide rod 6. A connecting rod 8 is hinged between the bottom of the slider 7 and the connecting plate 4. A horizontal cross cylinder 9 is fixedly connected to the slider 7. One end of the cross cylinder 9 is open and is fixedly connected to a suction cup 10. A cylinder 11 is fixedly installed on the inner wall of the cross cylinder 9. A piston 12 is fixedly connected to the free end of the cylinder 11. The electric push rod 3 is controlled to retract, causing the connecting plate 4 to move downward. Through the linkage of the hinged connecting rod 8, the two sets of sliders 7 slide synchronously towards each other along the guide rod 6. When the suction cup 10 contacts the material surface, the cylinder 11 starts to retract, causing the piston 12 to form a negative pressure inside the cross cylinder 9, thereby achieving dual positioning and fixing of the material.

[0026] like Figure 1-3As shown, in order to meet the processing requirements of different height specifications, the bottom of the frame 1 is provided with a U-shaped support 19. A hydraulic rod 20 is fixedly installed on the top of the support 19. The free end of the hydraulic rod 20 is fixedly connected to the bottom of the block. Limiting blocks 21 are fixedly connected to both the left and right side walls of the frame 1. Guide rails 13 are fixedly connected to both sides of the inner wall of the support 19. The limiting blocks 21 and the guide rails 13 are slidably connected, which can control the extension and retraction of the hydraulic rod 20, driving the entire frame 1 mechanism to rise and fall smoothly along the support 19 and the guide rails 13. The cooperation between the limiting blocks 21 and the guide rails 13 ensures the stability of the lifting process, so that the material can accurately reach the predetermined processing height position.

[0027] In practical use, the material to be processed is placed on the placement plate 2. The servo motor 16 can be turned on as needed. The meshing transmission of the worm gear 17 and worm wheel 18 can make the material rotate so that the corresponding face is aligned with the position of the suction cup 10. This operation can avoid manual adjustment and improve the convenience of use. When positioning the material, the electric push rod 3 is controlled to retract. The downward movement of the connecting plate 4 can make the two sets of sliders 7 slide relative to each other under the action of the connecting rod 8 until the two suction cups 10 are pressed against the surface of the material. Then, the cylinder 11 is controlled to retract so that the piston 12 slides inside the horizontal cylinder 9. The material can be positioned by the suction cup 10. The double positioning can ensure the stability of the material. The vertical position of the material can be adjusted by controlling the extension and retraction of the hydraulic rod 20. During the process, the limit block 21 slides on the guide rail 13, which increases the stability of the frame 1 when moving vertically.
