Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a deburring device for steel pipe ends. Background Technology

[0002] The headrest tube is the supporting structure of a car seat headrest. Its main function is to fix the headrest position, provide comfortable head support, relieve neck fatigue caused by long-term driving, and reduce neck injury in the event of a collision. Structurally, common headrest support tubes are hollow tubes. During the production process, long tubes need to be cut into the required lengths. The cut tubes have burrs at both ends, which need to be removed. Since the cut steel tubes are not long, efficient deburring is required during transport via a conveyor belt. However, the positioning of the steel tubes during transportation is crucial; stable positioning is necessary before deburring can proceed. Therefore, solving this problem is very important. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a deburring device for steel pipe ends, which solves the problems in the background art.

[0004] To achieve the above objectives, this utility model provides a deburring device for steel pipe ends, comprising two conveyor belts spaced apart on the left and right sides, the conveyor belts transporting steel pipes from back to front, and a working box on each side of the two conveyor belts that are far apart from each other. A working chamber is formed in the working box near the conveyor belt, and a grinding mechanism is installed in the working chamber. An upper limit mechanism is provided on the side of the working box near the conveyor belt to limit the top of the steel pipe. The bottom of the upper limit mechanism is a height-adjustable pressure block, which is connected to the grinding mechanism, allowing the pressure block and the grinding mechanism to adjust their height together. An end limit mechanism is provided in the working chamber on the side far from the conveyor belt to limit both ends of the steel pipe.

[0005] Preferably, the grinding mechanism includes a grinding motor, a grinding wheel is fixedly connected to the shaft surface at the rear output end of the grinding motor, the grinding wheel covers the end faces of multiple steel pipes, a bearing block is rotatably connected to the rear end of the shaft, and the grinding motor and the bearing block are fixedly connected to the side of the pressure block.

[0006] Preferably, the front and rear inner walls of the working chamber are respectively provided with slide rails, and the front side of the grinding motor and the rear side of the bearing block are provided with sliders that match the slide rails.

[0007] Preferably, the upper limit mechanism includes a side arm located at the top of the side of the work box, a threaded rod connected longitudinally through the side arm, the threaded rod being fixed to the side arm by a bolt assembly, a pressure block being connected to the bottom end of the threaded rod, springs being distributed at the bottom end of the pressure block, and a pressure plate being connected to the bottom end of all the springs, the pressure plate being in contact with the surfaces of both ends of the steel pipe.

[0008] Preferably, the end limiting mechanism includes an adjusting cylinder disposed on the side of the working box, the output end of the adjusting cylinder extending into the working chamber and connected to a limiting block, springs II distributed on the side of the limiting block, all the sides of springs II being connected to a limiting plate, and the limiting plate contacting the end face of the steel pipe.

[0009] Preferably, a second slide rail is provided on both the front and rear sides of the limiting block inside the working cavity, and a second slider matching the second slide rail is provided on both the front and rear sides of the limiting block.

[0010] The beneficial effects of this utility model are as follows: This utility model transports the cut steel pipe by placing both ends on two conveyor belts on the left and right. The steel pipe is transported into the working chamber, and its ends are limited by a segment limiting mechanism to ensure that the lateral position of the steel pipe remains unchanged. The surface of the steel pipe is limited by an upper limiting mechanism to ensure that the steel pipe does not jump. The two limiting mechanisms limit the position of the steel pipe to stabilize it. The steel pipe is rolled during the transport process in conjunction with the conveyor belts. Then, it is ground by a grinding mechanism. This can efficiently, quickly and stably remove the burrs from the ends of the steel pipe.

[0011] The grinding mechanism uses a grinding motor to drive grinding wheels to grind the end faces of multiple steel pipes. This allows for multiple grinding cycles of the rolling steel pipes during transport, resulting in a good grinding effect. The grinding motor and bearing block are fixedly connected to the pressure block, allowing for adjustment of the grinding wheel height to accommodate steel pipes of different diameters. The grinding motor and bearing block, through the cooperation of slider one and slide rail one, ensure the stability of the height adjustment process. The upper limit mechanism is connected to a threaded rod via a side arm threaded connection. The height of the pressure block can be adjusted by rotating the threaded rod with a tool. The pressure block is connected to a pressure plate via a spring one, which presses down on the steel pipe, thus achieving elastic limiting and ensuring smooth transport and grinding processes without causing damage.

[0012] The end limiting mechanism adjusts the position of the limiting plate by adjusting the cylinder to drive the limiting block to move laterally, so as to adapt to steel pipes of different lengths. The limiting block achieves orientation during the adjustment process through the cooperation of slider two and slide rail two. The limiting plate is connected to the limiting block through spring two to achieve elastic limiting, ensuring smooth transportation and grinding process and preventing damage.
