Description

Technical Field

[0001] This utility model relates to the technical field of pipe surface grinding devices, specifically to a steel-plastic composite pipe surface grinding device. Background Technology

[0002] Steel-plastic composite pipe, as a pipe material that combines the advantages of steel and plastic, has excellent corrosion resistance, pressure resistance and wear resistance, and is widely used in urban water supply and drainage systems, industrial pipeline systems, agricultural irrigation systems and building drainage systems.

[0003] When processing steel-plastic composite pipes, grinding is usually required to ensure the surface roughness meets the requirements. This grinding process typically involves using a grinding device. Commercially available grinding devices generally require manual operation, where the grinding head is held and moved along the surface of the steel-plastic composite pipe. This method is time-consuming and labor-intensive. Alternatively, some grinding devices are fixed to a worktable, requiring subsequent movement and rotation of the steel-plastic composite pipe for grinding. However, this method also requires considerable effort with each rotation and movement, affecting both convenience and efficiency. Therefore, we propose a surface grinding device for steel-plastic composite pipes. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a steel-plastic composite pipe surface grinding device, including a support cylinder 1, a gear ring 2 rotatably connected to the front end of the support cylinder 1, two symmetrical end plates 20 fixedly installed on the front side of the gear ring 2, a second cylinder 21 fixedly installed on the end plate 20, and a grinding disc 22 provided at the end of the telescopic shaft of the second cylinder 21. The grinding disc 22 abuts against the surface of the steel-plastic composite pipe and then the grinding operation is realized by the rotation of the grinding disc 22.

[0028] Specifically, a first servo motor 23 is fixedly installed on the cylinder body of the support cylinder 1, and a drive gear 24 is fixedly installed at the end of the output shaft of the first servo motor 23. The drive gear 24 meshes with the gear ring 2 to drive the grinding disc 22 to rotate for grinding operation.

[0029] Specifically, multiple sets of first cylinders 11 arranged at equal intervals are fixedly installed on the inner wall of the support cylinder 1. The multiple first cylinders 11 in each set are arranged in a ring at equal intervals. A U-shaped seat 12 is fixedly installed at the end of the telescopic shaft of the first cylinder 11. A steel wheel 121 is rotatably connected between the upper and lower plates of the U-shaped seat 12 through a rotating shaft. The steel wheel 121 abuts against the steel-plastic composite pipe for clamping operation. At the same time, since the steel wheel 121 can rotate, it helps to reduce the friction between it and the steel-plastic composite pipe, making it easier to push the steel-plastic composite pipe forward.

[0030] In this embodiment, a fixed plate 211 is fixedly installed at the end of the telescopic shaft of the second cylinder 21, and the grinding plate 22 is fixedly installed on the fixed plate 211 by multiple fastening bolts, which facilitates the fixed installation operation.

[0031] Specifically, a bearing 10 is fixedly installed on the front end of the support cylinder 1, and a gear ring 2 is fitted onto the bearing 10 and fixedly installed on the outer ring of the bearing 10, so that the gear ring 2 can rotate freely.

[0032] Furthermore, a support frame 13 is fixedly installed at the bottom of the support cylinder 1. The support frame 13 is fixedly installed on the external base to provide support.

[0033] In addition, a horizontally arranged guide rail 3 is provided on one side of the gear ring 2. A second servo motor 30 is fixedly installed at the end of the guide rail 3. A lead screw 31 is fixedly installed at the end of the output shaft of the second servo motor 30. A slider 32 is threadedly connected to the lead screw 31. The slider 32 is slidably connected to the guide rail 3. A pusher plate 33 is fixedly installed at the end of the slider 32. A lifting rod 331 is fixedly installed on the side of the pusher plate 33. The lifting rod 331 faces the gear ring 2, so that the steel-plastic composite pipe is pushed forward to perform the grinding operation by moving the pusher plate 33.

[0034] It is worth noting that a fixing rod 35 is fixedly installed at the rear end of the guide rail 3, and the fixing rod 35 is fixedly installed on the support cylinder 1. A support leg 34 is fixedly installed at the front end of the guide rail 3, and the support leg 34 is fixedly installed on the external base to realize the support operation of the guide rail 3.

[0035] When using the steel-plastic composite pipe surface grinding device of this utility model, one end of the steel-plastic composite pipe is inserted into the support cylinder 1. At the same time, the second servo motor 30 is started and put into operation. When the second servo motor 30 is working, its output shaft rotates, which drives the lead screw 31 to rotate. The rotation of the lead screw 31 drives the slider 32, which is threaded to it, to move. The movement of the slider 32 drives the push plate 33 and the lifting rod 331 to move, so that the lifting rod 331 is inserted into the other end of the steel-plastic composite pipe. Then, the first cylinder 11 is started and put into operation. When the first cylinder 11 is working, its telescopic shaft extends, which drives the steel wheel 121 to press against the steel-plastic composite pipe for clamping operation.

[0036] Next, the second cylinder 21 is started and put into operation. When the second cylinder 21 is working, its telescopic shaft extends and drives the grinding disc 22 to press against the steel-plastic composite pipe. Then, the first servo motor 23 is started and put into operation. When the first servo motor 23 is working, its output shaft rotates and drives the drive gear 24 to rotate. The drive gear 24 rotates and drives the gear ring 2 that meshes with it to rotate. The gear ring 2 rotates and drives the second cylinder 21 and the grinding disc 22 to rotate. The grinding disc 22 rotates along the surface of the steel-plastic composite pipe to realize the grinding operation.

[0037] After the grinding of this part is completed, the second servo motor 30 is started again, and the pusher plate 33 is used to push the steel-plastic composite pipe forward to perform grinding operations on other parts. After the grinding of this end of the steel-plastic composite pipe is completed, the other end is ground in reverse.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
