Description

Technical Field

[0001] This utility model relates to the field of burr trimming, specifically a device for trimming burrs on the seams of steel barrels. Background Technology

[0002] Seam welding is a resistance welding process that forms a continuous weld seam by continuously rolling a roller electrode, and is often used for joining thin plate structures. After welding, the weld seam edges may develop burrs due to excessive current, uneven pressure, electrode wear, or gaps in plate assembly, which not only affect the appearance and dimensional accuracy, but may also lead to stress concentration, scratches on the workpiece or personnel, requiring repair.

[0003] Currently, existing technologies still have the following shortcomings: Firstly, the position of the repair mechanism is fixed and cannot be flexibly adjusted according to the diameter of the steel drum and the position of the weld, resulting in poor adaptability to steel drums of different specifications. Secondly, the angle of the grinding wheel is not adjustable, which makes it difficult to thoroughly remove burrs in different directions at the joint of the steel drum, and easily leads to uneven local repairs. Third, the steel drum lacks a stable positioning and guiding structure during the trimming process, and is prone to displacement due to vibration, resulting in a decrease in the trimming accuracy of the rough edges.

[0004] Therefore, a device for trimming burrs on the weld seams of steel barrels is proposed to address the above problems. Summary of the Invention

[0017] Please see Figures 1-5 As shown, a steel barrel seam weld burr trimming device includes a main body 1. A movable trimming component 2 is provided on the top of the main body 1. The movable trimming component 2 includes a movable part 3 and a grinding part 4. The movable part 3 includes a fixed frame 21 installed on the top of the main body 1. Two slide rails 22 are fixedly installed on the top of the fixed frame 21. Several sliders 24 are slidably installed on the two slide rails 22 respectively. Several sliders 24 are fixedly installed on the bottom of the movable frame 25. A placement frame 26 is fixedly installed on the top of the movable frame 25. During operation, the steel drum to be repaired is placed on the placement rack 26. The movable rack 25 slides along the slide rail 22 via the bottom slider 24, moving the steel drum to the grinding position. The cooperation between the slide rail 22 and the slider 24 ensures that the movement is smooth and without deviation, providing a foundation for subsequent precise repair.

[0018] Furthermore, the movable component 3 also includes a rack 27, which is fixedly installed on one side of the movable frame 25. The bottom of the rack 27 is meshed with a gear 28, which is fixedly installed on the output end of the servo motor 23. During operation, the servo motor 23 starts and drives the gear 28 to rotate. The gear 28 meshes with the rack 27 to drive the movable frame 25 to move linearly along the slide rail 22. Through the precise control of the servo motor 23, the steel barrel can be moved at a fixed distance to meet the trimming needs of burrs in different positions.

[0019] Furthermore, the grinding component 4 includes a hydraulic cylinder 31, a piston rod 32 is movably mounted on the output end of the hydraulic cylinder 31, a connecting rod 33 is hinged to one end of the piston rod 32, and a rotating frame 34 is hinged to the other end of the connecting rod 33. During operation, the hydraulic cylinder 31 drives the piston rod 32 to extend and retract, which in turn drives the rotating frame 34 to rotate around the hinge point of the base 11 via the connecting rod 33, thereby adjusting the contact angle between the abrasive belt 38 and the weld burrs on the steel barrel, adapting to the trimming of burrs in different tilt directions.

[0020] Furthermore, the grinding component 4 also includes a stepper motor 36, which is fixedly mounted on the top of the rotating frame 34. The output end of the stepper motor 36 is fixedly mounted with a drive pulley 37. The outer surface of the drive pulley 37 is connected to a sanding belt 38. The other side of the sanding belt 38 is connected to a support pulley 41 and a driven pulley 39. The support pulley 41 and the driven pulley 39 are rotatably mounted in the inner cavity of the adjusting arm 35. The adjusting arm 35 is fixedly mounted on one side of the rotating frame 34. During operation, the stepper motor 36 drives the drive pulley 37 to rotate, and the abrasive belt 38 rotates at high speed under the support of the drive pulley 37, the driven pulley 39 and the support pulley 41 to grind and repair the burrs on the weld seams of the steel drum. The support pulley 41 can enhance the tension of the abrasive belt 38 to ensure uniform grinding force. The adjusting arm 35 can finely adjust the position of the pulley to adapt to the treatment of burrs of different thicknesses.

[0021] Furthermore, the main body 1 includes a base 11, and a protective cover 12 is fixedly installed on one side of the base 11; During operation, the protective cover 12 can block metal shavings generated during the grinding process from flying, protecting the operator's safety and reducing the contamination of other parts of the equipment by the shavings.

[0022] Furthermore, a servo motor 23 is fixedly installed on one side of the base 11, a hydraulic cylinder 31 is hinged to one side of the base 11, and a rotating frame 34 is hinged to the top of the base 11. During operation, the base 11 provides stable support for the servo motor 23, hydraulic cylinder 31 and rotating frame 34, ensuring that each component maintains structural rigidity during operation and reducing the impact of vibration on the finishing accuracy.

[0023] Working principle: The steel drum to be repaired is placed on the placement rack 26. The servo motor 23 drives the movable frame 25 to move along the slide rail 22 through the meshing of the gear 28 and the rack 27, accurately delivering the steel drum to the grinding area. Subsequently, the hydraulic cylinder 31 adjusts the angle of the rotating frame 34 through the piston rod 32 and the connecting rod 33, so that the abrasive belt 38 fits against the weld burrs of the steel drum. The stepper motor 36 drives the abrasive belt 38 to rotate at high speed to grind and repair the burrs. The protective cover 12 protects against flying debris. During the repair process, the movement of the steel drum is controlled by the servo motor 23, which can realize the fully automated repair process and ensure that the burrs are treated evenly and accurately.
