Description

Technical Field

[0001] This utility model relates to the field of steel component grinding technology, specifically a grinding device for seamless welding of subway steel components. Background Technology

[0002] Steel component grinding refers to the process of using specific tools to treat the welded parts and surrounding surfaces of steel components to remove impurities, oxide scale, etc., so that the surface of the steel components reaches a certain level of cleanliness and flatness to meet welding requirements. When grinding the welded joints of steel components, appropriate grinding equipment is required.

[0003] According to the utility model patent application CN220993853U, a steel bar end grinding device is disclosed. While this device uses a worm gear that meshes with a worm wheel to drive a transmission shaft, which in turn rotates the base plate and vertical plate, with the vertical plate's rotation angle determining the grinding angle, and then a motor is started, the motor's operation drives a rotating shaft via a coupling. This rotating shaft then drives a grinding wheel. The user places the steel bar to be ground into a matching groove on the grinding table and holds the steel bar to press the grinding end against the grinding wheel. This grinding device can be operated by a single person, and while grooves of different inner diameters are suitable for steel bars of different thicknesses, allowing the grinding angle to be determined according to actual needs, manual adjustment of the steel bar's orientation is still required. The lack of an automatic grinding structure that can automatically adjust the grinding orientation makes manual adjustment of the steel bar time-consuming and labor-intensive. Therefore, we provide a grinding device for seamless welding of subway steel components to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a grinding device for seamless welding of subway steel components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for seamless welding of subway steel components, including a base, an orientation adjustment mechanism and an automatic grinding mechanism respectively arranged above the base, and a steel component arranged inside the orientation adjustment mechanism; The orientation adjustment mechanism includes a U-shaped frame and an arc-shaped bracket. A button controller is fixedly connected to the left side of the U-shaped frame. A hydraulic rod is fixedly connected to the inner wall of the U-shaped frame. A lifting plate is fixedly connected to the telescopic end of the hydraulic rod. A linear motor is fixedly connected to the bottom surface of the lifting plate. A pressure plate is fixedly connected to the output end of the linear motor. Several identical small supports are fixedly connected to the inner wall of the arc-shaped bracket. A rotating rod is fixedly connected to the inner wall of each small support. A small rotating cylinder is fixedly connected to the outer surface of each rotating rod. The automatic polishing mechanism includes a movable frame, a first electric telescopic rod fixedly connected to the inner wall of the base, a second electric telescopic rod fixedly connected to the inner bottom wall of the movable frame, a lifting frame fixedly connected to the telescopic end of the second electric telescopic rod, a drive motor fixedly connected to the inner wall of the lifting frame, a power rod fixedly connected to the output end of the drive motor, and a shaped polishing wheel fixedly connected to the outer surface of the power rod.

[0006] Furthermore, the bottom surfaces of the U-shaped frame and the arc-shaped bracket are both fixedly connected to the upper surface of the base. The outer surface of each small rotating cylinder is in contact with the outer surface of the steel component. The telescopic end of the first electric telescopic rod is fixedly connected to the back of the moving frame. The back of the lifting frame is in contact with the inner wall of the moving frame. The hydraulic rod, linear motor, first electric telescopic rod, second electric telescopic rod, and drive motor are all electrically connected to the button controller via wires. A handle is fixedly connected to the upper surface of the base, and an anti-slip sleeve is fixedly connected to the outer surface of the handle.

[0007] Furthermore, four connecting posts are fixedly connected to the bottom surface of the base, and each connecting post is fixedly connected to a caster wheel at its bottom end.

[0008] Furthermore, an anti-slip pad is fixedly connected to the bottom surface of the pressure plate, and the bottom surface of the anti-slip pad is in contact with the outer surface of the steel component.

[0009] Furthermore, a first limiting slider is fixedly connected to the bottom surface of the movable frame, and the outer surface of the first limiting slider is slidably connected to the inside of the base.

[0010] Furthermore, a second limiting slider is fixedly connected to the back of the lifting frame, and the outer surface of the second limiting slider is slidably connected to the interior of the moving frame.

[0012] Compared with existing technologies, this grinding device for seamless welding of subway steel components has the following advantages: 1. This utility model utilizes the cooperation of a base, U-shaped frame, button controller, hydraulic rod, lifting plate, linear motor, pressure plate, arc-shaped bracket, small support, rotating rod, small rotating cylinder, and steel components. Operating the button controller allows the hydraulic rod to extend, thereby controlling the pressure plate to press against the steel components. The small rotating cylinders within the arc-shaped bracket rotate around the rotating rod. Furthermore, when the button controller controls the linear motor to move the pressure plate left and right, the steel components within the arc-shaped bracket, held by the rolling small rotating cylinders and the left-right movement of the pressure plate, can rotate stably, thus adjusting the orientation of the steel component's welding end and achieving a time-saving and labor-saving effect.

[0013] 2. This utility model utilizes the cooperation of a base, a first electric telescopic rod, a moving frame, a second electric telescopic rod, a lifting frame, a drive motor, a power rod, a shaped grinding wheel, and a button controller. The button controller can control the extension and retraction of the first and second electric telescopic rods, thereby controlling the relative position of the two grinding surfaces of the shaped grinding wheel with the joint to be welded on the steel component. Furthermore, the button controller can energize the drive motor to drive the power rod and the shaped grinding wheel to rotate, enabling the shaped grinding wheel to perform multi-directional and rapid grinding of the steel component whose posture is constantly being adjusted. This saves time and effort, avoiding the time-consuming and labor-intensive problem of manually adjusting the steel component due to the lack of an automatic grinding structure that can automatically adjust the grinding direction.

By setting the connecting columns 4, the base 1 and the caster wheel 5 can be connected. By setting the caster wheel 5, the position of the entire grinding device can be easily moved.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 The inner wall of the arc-shaped bracket 207 is fixedly connected with several identical small supports 208. The inner wall of each small support 208 is fixedly connected with a rotating rod 209. The outer surface of each rotating rod 209 is fixedly connected with a small rotating cylinder 210. The outer surface of each small rotating cylinder 210 is in contact with the outer surface of the steel component 12. The bottom surface of the pressure plate 206 is fixedly connected with an anti-slip pad 11. The bottom surface of the anti-slip pad 11 is in contact with the outer surface of the steel component 12. By setting the anti-slip pad 11, the anti-slip property of the bottom surface of the pressure plate 206 can be increased. In turn, it can cooperate with multiple rotating small rotating cylinders 210 to make the rotation of the steel component 12 smoother and less prone to slipping, thereby improving the grinding effect of the steel component 12.

By setting the second limiting slider 9, it can slide up and down in a directional manner inside the moving frame 302, thereby increasing the stability of the lifting frame 304 relative to the moving frame 302 in a directional up and down manner.

[0023] Reference Figure 1 , Figure 5 and Figure 6 A power rod 306 is fixedly connected to the output end of the drive motor 305. A special-shaped grinding wheel 307 is fixedly connected to the outer surface of the power rod 306. The special-shaped grinding wheel 307 is composed of two cylindrical grinding discs with different inner diameters. The front of the larger inner diameter grinding disc can grind the end of the steel component 12, while the smaller inner diameter grinding disc can grind the periphery of the end of the steel component 12. A coupling 10 is fixedly connected to the outer surface of the output end of the drive motor 305. The inner wall of the coupling 10 is fixedly connected to the outer surface of the power rod 306. By setting the coupling 10, the connection between the output end of the drive motor 305 and the power rod 306 can be strengthened, thereby increasing the rotational stability of the power rod 306.

[0024] Working principle: In use, the steel component 12 is placed inside the arc-shaped bracket 207. Then, the button controller 202 is operated to control the hydraulic rod 203 to extend, thereby pressing the pressure plate 206 against the steel component 12 until the anti-slip pad 11 and the small rotating cylinders 210 inside the arc-shaped bracket 207 clamp the steel component 12 tightly. Then, the button controller 202 is operated to control the linear motor 205 to drive the pressure plate 206 to move left and right. The steel component 12, which is held by the small rotating cylinders 210 rolling and the pressure plate 206 moving left and right inside the arc-shaped bracket 207, rotates stably, thereby continuously adjusting the orientation of the end of the steel component 12 to be welded. Then, the button controller 202 controls the... The extension of the electric telescopic rod 301 and the extension of the second electric telescopic rod 303 are controlled, thereby controlling the two grinding surfaces of the irregular grinding wheel 307 to gradually approach the steel component 12 to be welded. During this period, the button controller 202 automatically controls the drive motor 305 to be energized, driving the power rod 306 and the irregular grinding wheel 307 to rotate, thereby enabling the irregular grinding wheel 307 to perform multi-directional rapid grinding on the steel component 12 whose posture is constantly adjusted, which saves time and effort. The design of the entire steel component welding head grinding device effectively solves the problem that the manual adjustment of steel components is time-consuming and labor-intensive due to the lack of an automatic grinding structure that can automatically adjust the grinding position.
