Description

Technical Field

[0001] The utility model relates to the field of composite pipelines, in particular to a top pipe end surface finishing device. Background Art

[0002] It is common for large-diameter glass fiber composite pipes to have uneven end faces and non-parallel end faces after they are produced. When such pipes are butt-jointed, the two end faces are not completely in close contact, but partially in contact, which generates local stress, causing the pipe to shift, and even causing damage to the pipe joints and leakage at the interface. There is a need to trim the ends of the pipes. However, due to the large diameter of large-diameter pipes, traditional methods cannot be used to clamp the pipes. In addition, due to the long length of the pipes, the axis of the pipes is easily affected by the clamping and deviates. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a top pipe end surface finishing device which can flatten the end surface of a large-diameter pipeline.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a top pipe end surface finishing device, including a rotating mechanism, a driving mechanism, a grinding mechanism, and a cutting mechanism;

[0005] The rotating mechanism comprises a rotating disk and a base, wherein the rotating disk is rotatably arranged at the front side of the base;

[0006] The grinding mechanism is arranged in front of the rotating mechanism, and the grinding mechanism includes a grinding head, a grinding head frame, a first slide seat, and a second slide seat. The grinding head can rotate around a horizontal axis and is arranged on the grinding head frame. The grinding head frame can move forward and backward and is arranged on the first slide seat. The first slide seat can move left and right and is arranged on the second slide seat. The second slide seat can move forward and backward and is arranged in front of the rotating mechanism.

[0007] The driving mechanism is arranged between the rotating mechanism and the grinding mechanism, and the driving mechanism comprises a first track, two first roller seats, and two first rubber rollers. The two first rubber rollers can be respectively arranged on the two first roller seats and can rotate around a rotating shaft parallel to the horizontal axis. The two first roller seats can be moved left and right and arranged on the first track.

[0008] The cutting mechanism is arranged at the side of the grinding mechanism, and comprises a cutting base and a cutting head, and the cutting head is arranged on the cutting base in a manner that it can move leftward and rightward.

[0009] The pipe can be placed on the two first rubber rollers of the driving mechanism, and the first rubber rollers can be driven to rotate to drive the pipe to rotate. Because the center height of the rotating disk has been adjusted according to the diameter and thickness of the pipe before placing the pipe, so that the rotating axis of the rotating disk coincides with the axis of the pipe, the rear end of the pipe can be positioned against the rotating disk. When the pipe rotates, the rotating disk can rotate with the pipe, and the positioning point of the rear end of the pipe and the rotating disk will not change. The cutting mechanism can feed and cut the pipe from the left and right directions, and the grinding head of the grinding mechanism can grind the front end of the pipe. After the front end of the pipe is processed, the pipe can be lifted and the front and rear ends can be turned, so that the trimmed end can be against the rotating disk to trim the other end of the pipe.

[0010] The pipeline is supported by two first rubber rollers at the bottom and driven to rotate by the first rubber hose, so no clamping force is applied to the pipeline, and the pipeline is not easily deformed. The rear end of the pipeline is positioned against the rotating disk, and there is no need to clamp the pipeline. The rotating disk can rotate with the pipeline to provide a stable positioning point for the pipeline. The cutting mechanism and grinding mechanism of the pipeline can stably process a flat front end surface.

[0011] Preferably, it further comprises a plurality of roller mechanisms, which are arranged in a row along the front-to-back direction between the driving mechanism and the grinding mechanism, each roller mechanism comprises a roller frame and two rollers, the roller frame can move forward and backward, and the two rollers can move left and right and be arranged on the roller frame. The plurality of rollers can support the pipeline at different positions by moving forward and backward, thereby reducing the deformation of the pipeline. The supporting point can be changed by moving the rollers left and right according to the diameter of the pipeline.

[0012] Preferably, it also includes a main track and a side track, the main track is arranged in parallel with the side track, the roller frame and the second slide can be moved forward and backward on the main track, and the cutting base can be moved forward and backward on the side track.

[0013] Preferably, the base includes a base body and a lifting slide, the lifting slide can be moved up and down on the base body, and the rotating disk can be rotatably arranged on the lifting slide. The height of the lifting slide can be adjusted according to the diameter of the pipeline, thereby adjusting the height of the center of the rotating disk so that the center of the rotating disk is aligned with the axis of the pipeline.

[0014] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model can trim the two end faces of the pipeline so that the two end faces are parallel to each other and perpendicular to the pipeline axis, and the processing accuracy is further improved, which solves the problem that the two end faces in contact during pipeline jacking are not completely in close contact, there is local contact, local stress is generated, the pipeline is displaced, and even the pipe joints are damaged and the interface leaks.
