Description

A beveling and grinding device for fiberglass pipe ends Technical Field

[0001] This utility model relates to the technical field of steel pipe grinding, and in particular to a device for grinding and trimming the bevel of the end face of a fiberglass pipe. Background Technology

[0002] After FRP pipes are manufactured, the end faces are prone to beveling due to processing. When beveling occurs, the beveling of the FRP pipe needs to be reprocessed to ensure the quality of the FRP pipe. Currently, since operators often hold the steel pipe and make it contact the grinding wheel, the grinding angle is prone to be too large during the contact between the bevel of the steel pipe end face and the grinding wheel, which can lead to damage to the FRP pipe during processing. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a bevel grinding device for the end face of a fiberglass pipe.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a beveling and grinding device for fiberglass pipe ends, comprising a steel pipe grinding machine base and two drive motors. The steel pipe grinding machine base has a processing cavity opening on its exterior. The two drive motors are respectively fixedly connected to both sides inside the processing cavity opening. A grinding wheel is fixedly connected to the exterior of the output shaft of each drive motor. The grinding wheel is used to grind the ends of the fiberglass pipe. Two fixed beam rings are fixedly connected to the exterior of the steel pipe grinding machine base. Each fixed beam ring has a rotating bearing inside. The outer ring of the rotating bearing is fixedly connected to the fixed beam ring, and the inner rings of the two rotating bearings... Each component is fixedly connected with an inner fixing ring, which rotates within the two fixed beam rings via two rotating bearings. The annular transmission cylinder is located inside the two inner fixing rings and rotates above the outside of the steel pipe grinding machine platform via the two inner fixing rings. The annular transmission cylinder is cylindrical in shape and has a slot in the middle for easy observation by the operator. The annular transmission cylinder is equipped with a fixing component for fixing the fiberglass pipe on its outside. A rotating handle is fixedly connected to the outside of the annular transmission cylinder, allowing the operator to rotate the entire annular transmission cylinder. The rotating handle is disc-shaped.

[0005] As a preferred technical solution of this utility model, the fixing component includes two through slots and a crossbeam plate. The two through slots are respectively opened on both sides of the outside of the annular conduction cylinder and are connected to the inside of the annular conduction cylinder. Each through slot is slidably connected to a guide rod, which is L-shaped. The crossbeam plate is fixedly connected to the outside of the annular conduction cylinder. A bidirectional screw is provided at the end of the crossbeam plate away from the annular conduction cylinder. Both sides of the bidirectional screw are provided with threads that are opened in opposite directions. The two ends of the bidirectional screw are respectively spirally passed through the opposite sides of the two guide rods. The two ends of the bidirectional screw are threadedly connected to the two guide rods through two threaded grooves opened on its outside.

[0006] As a preferred technical solution of this utility model, the outer side of the crossbeam plate is provided with an outer groove, the middle section of the bidirectional screw is located inside the outer groove, a rotating gear is provided inside the outer groove, the rotating gear is fixedly connected to the outside of the bidirectional screw, and the bidirectional screw is driven to rotate inside the outer groove by rotating the rotating gear, and the rotation of the bidirectional screw drives the guide rods on both sides to perform synchronous helical transmission.

[0007] As a preferred technical solution of this utility model, clamping plates are fixedly connected to the opposite sides of the two guide rods. The two clamping plates are movably connected to both sides inside the annular conduction cylinder, and the two clamping plates are located on the upper and lower sides inside the annular conduction cylinder, respectively.

[0008] As a preferred technical solution of this utility model, limit plates are fixedly connected to both sides of the outer side of the crossbeam plate. Each limit plate has an inner groove, and a positioning ring is rotatably connected inside each inner groove. The positioning ring is fixedly connected to the outside of the bidirectional screw, and the bidirectional screw is positioned outside the limit plate through the positioning ring and the inner groove.

[0009] As a preferred technical solution of this utility model, each inner fixing ring has an inner ring groove, and a positioning slide plate is slidably connected inside each inner ring groove. The end of the positioning slide plate away from the inner ring groove is fixedly connected to the outside of the annular conduction cylinder. The annular conduction cylinder rotates or moves laterally inside the two inner fixing rings through the positioning slide plates set on both sides.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0011] 1. By aligning one side of the bevel of the fiberglass pipe with the positions of the two grinding wheels, and simultaneously fixing and clamping the fiberglass pipe inside the annular transmission cylinder, the rotating handle is then pushed towards the grinding wheels. The rotating handle drives the annular transmission cylinder to make the end face of the bevel of the fiberglass pipe horizontally contact the two grinding wheels. The drive motor drives the grinding wheels to rotate, making them contact the cross-section of the bevel of the fiberglass pipe for grinding, thereby achieving a fast, stable, and uniform grinding effect on the end face of the bevel of the fiberglass pipe.

[0012] 2. By passing the fiberglass tube through the inside of the annular conduction cylinder and placing the fiberglass tube between two clamping plates, and with the two clamping plates set inside the fixing component, the two guide rods approach each other and drive the clamping plates to press against the two sides of the outside of the fiberglass tube. The two clamping plates clamp the fiberglass tube quickly and securely, thus achieving the effect of quickly fixing the fiberglass tube inside the annular conduction cylinder.

[0013] 3. By setting two inner ring grooves in conjunction with two positioning slides, the two positioning slides limit the position of the annular conduction cylinder inside the two inner fixed rings, preventing the annular conduction cylinder from detaching from the two inner fixed rings when moving laterally. At the same time, the cooperation between the inner ring grooves and the positioning slides assists the annular conduction cylinder in stable horizontal movement, improving the stability of the movement after the fiberglass pipe is clamped.

The annular transmission cylinder 20 rotates or moves laterally inside the two inner fixed rings 21 through the positioning slide plates 23 set on both sides.

[0022] The annular conduction cylinder 20 is externally equipped with a fixing assembly for securing the fiberglass pipe. The fixing assembly includes two through slots 31 and a crossbeam plate 32. The two through slots 31 are respectively located on both sides of the annular conduction cylinder 20 and communicate with the interior of the annular conduction cylinder 20. A guide rod 30, L-shaped, is slidably connected inside each through slot 31. The crossbeam plate 32 is fixedly connected to the exterior of the annular conduction cylinder 20. A bidirectional screw 33 is located at the end of the crossbeam plate 32 away from the annular conduction cylinder 20. The two sides of the bidirectional screw 33 have opposing threads.

[0023] Working principle:

[0024] Before use: By passing the fiberglass tube through the inside of the annular conduction cylinder 20 and placing the fiberglass tube between the two clamping plates 36, the rotating gear disk 34 drives the bidirectional screw 33 to rotate synchronously inside the crossbeam plate 32. The rotation of the bidirectional screw 33 drives the threads on both sides of it to perform helical transmission with the two guide rods 30. When the bidirectional screw 33 rotates, the two guide rods 30 are driven by the helical transmission to move towards each other. The two guide rods 30 approach each other and drive the clamping plates 36 to press against the two sides of the outside of the fiberglass tube. The two clamping plates 36 clamp the fiberglass tube quickly and securely, achieving the effect of quickly fixing the fiberglass tube inside the annular conduction cylinder 20.
