Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe processing equipment, specifically a device for removing weld beads from sanitary stainless steel pipes. Background Technology

[0002] In the production and processing of sanitary stainless steel pipes, weld beads are generated after the pipes are welded. These weld beads not only affect the appearance of the pipes, but may also become a hidden danger of impurity accumulation and bacterial growth in subsequent use. Therefore, it is necessary to remove the weld beads.

[0003] Traditional methods of weld bead removal often involve manual hand-held grinding, which suffers from low efficiency, inconsistent grinding quality, and high labor intensity, making it difficult to meet the high-precision, high-quality processing requirements of sanitary stainless steel pipes. Furthermore, some existing automated grinding equipment has complex structures, is inconvenient to adjust, cannot flexibly adapt to grinding weld beads on pipes of different specifications, and is prone to vibration during the grinding process, affecting the grinding effect.

[0004] Therefore, there is an urgent need for a sanitary stainless steel pipe weld removal device with a reasonable structure, convenient adjustment, and good polishing effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a device for removing weld beads from sanitary stainless steel pipes, thus solving the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a weld bead removal device for sanitary stainless steel pipes, comprising a drive assembly, a balancing assembly, and a weld bead grinding mechanism. The drive assembly is connected to the balancing assembly in a transmission manner, and the weld bead grinding mechanism is mounted on the balancing assembly. The drive assembly provides power, the balancing assembly ensures the stability of the grinding process, and the weld bead grinding mechanism performs the weld bead grinding operation.

[0009] The drive assembly includes a drive motor, a drive shaft, a control handle, a power supply, and a support frame. The drive motor, as the power source, connects to the drive shaft at its output end to provide rotational power. The control handle is located on the drive motor, allowing operators to easily control the equipment's start / stop and adjust operating parameters. The power supply is located beside the drive motor, providing power and freeing the equipment from power cord constraints, facilitating flexible use in various working environments. The support frame is located at the bottom of the drive motor, providing support and placement for it.

[0010] Specifically, the drive motor is a steplessly speed-adjustable servo motor, capable of precisely adjusting the speed according to actual grinding needs. The drive motor and control handle are electrically connected via a wire, and the control handle has buttons for adjusting the drive motor speed and controlling its start / stop, making operation convenient. The power bank is a rechargeable lithium battery pack with large capacity and long battery life. The power bank and drive motor are connected via a power cord with overload and short-circuit protection to ensure electrical safety. The support frame is made of aluminum alloy, which is lightweight and strong. The support frame is connected to the drive motor with detachable bolts for easy installation, disassembly, and maintenance. The bottom of the support frame has anti-slip rubber pads to increase the stability of the equipment and prevent slippage.

[0011] The balancing assembly includes a balancing drive shaft, a connecting bracket, a balancing bushing, and a shaft hole. The balancing drive shaft is connected to the drive shaft to transmit power from the drive motor; the connecting bracket is fixedly connected to the drive motor, serving as a connection and support; the balancing bushing is fixedly connected between the two connecting brackets, and the shaft hole is formed in the balancing bushing. The balancing drive shaft passes through the shaft hole, and the balancing bushing limits and stabilizes the rotation of the balancing drive shaft, ensuring smooth power transmission.

[0012] The balance drive shaft and the drive shaft are connected by a coupling. This coupling is a flexible coupling, which effectively buffers vibrations during transmission, preventing vibrations from affecting grinding accuracy. The connecting frame and the balance drive shaft are integrally formed, ensuring structural strength. The connecting frame is made of high-strength alloy steel, possessing excellent structural strength and wear resistance, extending the equipment's service life. The balance bushing's shaft hole and the balance drive shaft have a clearance fit, ensuring smooth rotation of the balance drive shaft while also limiting its movement. Furthermore, the inner wall of the balance bushing's shaft hole is coated with a wear-resistant ceramic coating, reducing wear between the two and further improving the equipment's stability and durability.

[0013] The weld grinding mechanism includes a rotating support, a groove, a strip groove, an adjusting seat, adjusting fastening bolts, and a grinding rod. The rotating support is connected to the balance drive shaft and rotates together with it. The groove is formed on the rotating support to accommodate part of the adjusting seat structure. The strip groove communicates with the groove, providing space for the movement of the adjusting fastening bolts and the adjustment of the adjusting seat position. The adjusting seat is mounted on the rotating support via the adjusting fastening bolts and can be adjusted along the direction of the strip groove to adapt to the weld grinding requirements of different pipe specifications. The grinding rod is set on the adjusting seat and is used to directly contact the pipe weld for grinding operations.

[0014] In detail, the adjusting seat and the rotating support are detachably connected via adjusting fastening bolts. These bolts are hexagonal socket head cap screws, easy to operate, and compatible with the slotted groove, allowing movement along the groove to adjust the position of the adjusting seat, thereby adjusting the working position of the grinding rod. The grinding rod uses a diamond grinding head, which is high in hardness and wear-resistant, resulting in excellent grinding performance. The grinding rod and the adjusting seat are connected by threads, facilitating the replacement of different specifications of grinding rods to meet various grinding needs, such as weld bead thickness and pipe diameter, thus improving the equipment's versatility.
