Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel column processing technology, and in particular relates to a port grinding device for steel column processing. Background Technology
[0002] Steel column processing refers to the process of processing steel into steel columns of specific shapes and sizes. It mainly includes processes such as cutting, welding, and grinding. Steel columns are widely used in structures such as buildings and bridges to play a supporting and load-bearing role.
[0003] Chinese patent CN220260402U discloses a steel column end grinding device. The device comprises a second support plate and a guide assembly. The guide assembly includes two mounting plates fixed above the second support plate. A second threaded rod is rotatably arranged between the two mounting plates. A moving motor is fixed to the side of one of the mounting plates. The output shaft of the moving motor is connected to the second threaded rod via a coupling. A guide block is threaded onto the second threaded rod. The guide block has an installation groove, and an installation block is disposed inside the groove. A first grinding motor is fixed to the side of the installation block, and a first grinding head is fixed to the output shaft of the first grinding motor. A V-groove is formed above the installation block. A moving assembly is disposed above the second support plate, and a clamping assembly is disposed on the side of the second support plate. A U-shaped steel column is disposed on the clamping assembly. The moving assembly includes a U-shaped plate fixed above the second support plate. Two lifting grooves are formed on the inner side of the U-shaped plate, and sliding rods are slidably disposed inside the two lifting grooves. A sliding block is mounted on the upper part of the unit. A second grinding motor is fixed to one side of the sliding block, and a sleeve is fixed to the other side. The output shaft of the second grinding motor passes through the sleeve and is rotatably connected to the sleeve via a bearing. A second grinding head is fixed to the output shaft of the second grinding motor. Through the cooperation of the guide assembly and the sliding assembly, the first grinding motor drives the first grinding head to rotate via its output shaft. The first grinding head grinds the lower part of the U-shaped steel column end. The second grinding motor drives the sleeve to rotate via its output shaft, and the sleeve drives the second grinding head to rotate. The grinding head grinds the end of the U-shaped steel column. When the second grinding head comes into contact with the end of the U-shaped steel column, the mounting block moves the sleeve through the V-groove. The sleeve moves the second grinding head upward, thus grinding the side of the end of the U-shaped steel column. The grinding path is N-shaped. Afterward, the moving motor drives the second threaded rod to rotate in the opposite direction through the output shaft. The second threaded rod moves the guide block in the opposite direction, thus grinding the side of the end of the U-shaped steel column. This ensures that the end of the U-shaped steel column is fully ground, thus avoiding dead corners in the grinding of the steel column end.
[0004] However, existing technology can only grind the grinding motor at a fixed angle, which limits the grinding angle, makes grinding inflexible, and is inconvenient for conveying heavy steel. Therefore, it is necessary to design a port grinding device for steel column processing. Utility Model Content

The grinding height of the grinding roller is adjusted, and the grinding position of the grinding roller is adjusted by starting the slider two. Then, the conveying mechanism two is started to adjust the grinding width of the grinding roller to adapt to grinding at multiple angles. After grinding is completed, the electric push rod on the top of the conveyor table is started to push the suction cup downwards. The suction cup is activated to adsorb the steel column, causing one side to tilt up and be output from the conveying slot.

[0015] Preferably, the conveying slot is located away from the grinding roller and below the conveying plane on the top of the conveyor belt.
[0016] Compared with related technologies, the end grinding device for steel column processing provided by this utility model has the following beneficial effects: 1. The steel is clamped by the clamping and conveying mechanism. When the conveying mechanism is activated, the grinding roller is raised and lowered.

[0017] 2. By starting the electric push rod two, the two conveyor wheels on both sides extend towards each other to clamp the steel column. Then, start the motor two to make the conveyor wheels two rotate to push the input steel column. At this time, one end of the steel column extends to the top of the grinding hole, and the waste chips from the grinding roller are discharged into the interior of the grinding hole for collection.
[0018] 3. By setting slot one and slot two to limit the movement of slider two and slider one at the same time, slider two and slider one can be stably raised and lowered inside slot one and slot two when motor three is started.
