Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and specifically to a steel pipe polishing device. Background Technology

[0002] The invention, published on March 28, 2023, under the publication number CN115847267A, is titled "A Polishing Machine for Steel Pipes." It includes two connecting sleeves hinged together by a connecting seat. After a square steel pipe guardrail is wrapped and fixed using the two connecting sleeves and a fixing sleeve, a controller drives a grinding disc to polish the welded joints on two opposite surfaces of the steel pipe. Then, two adjusting slots rotate two top boxes, causing the controller and turntable to rotate to one side of the other two opposite surfaces for polishing. The rotation of adjusting rods in the adjusting blocks at both ends of the fixing frame causes the fixing blocks to contact the steel pipe surface. The two fixing blocks clamp the steel pipe and limit the polishing thickness, enabling automatic polishing. This prevents fatigue from prolonged hand-held polishing, improves work efficiency, enhances safety, and ensures consistent polishing results by adjusting and limiting the polishing thickness.

[0003] In the prior art, including the aforementioned patent, the steel pipe is clamped by the cooperation of two fixing blocks and the grinding thickness is limited. Automatic grinding and polishing can be achieved, but the grinding range of the steel pipe is small. After grinding, the position of the steel pipe needs to be readjusted before grinding, which makes the grinding cycle long. Utility Model Content

[0004] The purpose of this invention is to provide a steel pipe polishing device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steel pipe polishing device includes a housing, a turntable rotatably connected inside the housing, and a plurality of polishing parts and a transmission part slidably connected radially to the turntable. When the steel pipe is inserted into the turntable, the transmission part drives the polishing parts to abut against the steel pipe, thereby polishing the steel pipe.

[0007] The turntable has multiple first mounting slots in its radial direction that are adapted to the polished parts, and multiple second mounting slots in its radial direction that are adapted to the transmission parts. The first mounting slots and the second mounting slots are arranged alternately in sequence.

[0008] The polishing parts and the transmission parts are arranged alternately in sequence, and each polishing part is slidably connected to its corresponding transmission part.

[0009] A second pulley is rotatably connected inside the housing, and a first pulley is coaxially fixedly connected to the turntable. A belt is sleeved between the first pulley and the second pulley.

[0010] The second pulley is driven by a motor, and the motor is fixedly mounted on the housing.

[0011] In the above technical solution, the present invention provides a steel pipe polishing device, which has multiple polishing parts arranged radially on a turntable, and the turntable drives each polishing part to rotate, thereby polishing the circumference of the steel pipe and shortening the polishing time of the steel pipe.

[0012] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] Reference Figure 1-3 As shown, this utility model provides a steel pipe polishing device, including a housing 1, a turntable 1.1 rotatably connected inside the housing 1, and a plurality of polishing parts 1.13 and a transmission part 1.14 slidably connected in the radial direction of the turntable 1.1. When the steel pipe is inserted into the turntable 1.1, the transmission part 1.14 drives the polishing parts 1.13 to abut against the steel pipe, thereby polishing the steel pipe.

[0022] The turntable 1.1 has multiple first mounting grooves 1.10 that are adapted to the polishing part 1.13 in the radial direction, and the turntable 1.1 has multiple second mounting grooves 1.12 that are adapted to the transmission part 1.14 in the radial direction. The first mounting grooves 1.10 and the second mounting grooves 1.12 are arranged alternately in sequence.

[0023] Each polishing component 1.13 and each transmission component 1.14 are arranged alternately in sequence, and each polishing component 1.13 and its corresponding transmission component 1.14 are slidably connected in a one-to-one correspondence.

[0024] A second pulley 1.21 is rotatably connected inside the housing 1, and a first pulley 1.11 is coaxially fixedly connected to the turntable 1.1. A belt 1.20 is sleeved between the first pulley 1.11 and the second pulley 1.21.

[0025] The second pulley 1.21 is driven by the motor 1.3, and the motor 1.3 is fixedly mounted on the housing 1.

[0026] Reference Figure 1-3As shown, a feed inlet and a discharge outlet are respectively opened through both opposite ends of the housing 1. A turntable 1.1 is rotatably connected at the discharge outlet. A through hole is opened through the axis of the turntable 1.1. A first turntable 1.1 is coaxially fixedly connected to the turntable 1.1. Multiple first mounting grooves 1.10 and multiple second mounting grooves 1.12 are respectively opened radially at the end of the turntable 1.1. The first mounting grooves 1.10 and the second mounting grooves 1.12 are arranged alternately. A polishing part 1.13 adapted to it is slidably connected in each first mounting groove 1.10. Each polishing part 1.13 includes a first slider adapted to the first mounting groove 1.10 and an arc-shaped grinding part fixedly connected to the first slider. The second mounting grooves 1.12 are slidably connected in each second mounting groove 1.12. The device is connected to a transmission component 1.14 that is adapted to it. Each transmission component 1.14 includes a second sliding block adapted to the second mounting groove 1.12 and a V-shaped block fixedly connected to the second sliding block. Each arc-shaped grinding part is slidably connected to each V-shaped part. A screw 1.15 is rotatably connected to the turntable 1.1. The screw 1.15 is threadedly connected to one of the polishing parts 1.13. In this embodiment, the device is used in conjunction with a steel pipe traction machine (not shown in the figure). A second pulley 1.21 is rotatably connected to the frame. A belt 1.20 is sleeved between the second pulley 1.21 and the first pulley 1.11. The second pulley 1.21 is driven by a motor 1.3, which is fixedly installed inside the housing 1.

[0027] During use, when the user inserts the steel pipe into the axial position of the turntable 1.1, the screw 1.15 is manually rotated, causing the screw 1.15 to drive the corresponding polishing part 1.13 to move towards the axial direction of the turntable 1.1. This causes the transmission parts 1.14 and the polishing parts 1.13 to move synchronously until the polishing parts 1.13 just contact the side wall of the steel pipe and the steel pipe can be polished by the polishing parts 1.13. However, the turntable 1.1 does not rotate during rotation, and the steel pipe moves in the axial direction of the turntable 1.1 under the action of the traction machine, thereby achieving the polishing of the steel pipe.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
