[0002] Pipe joints are used for pipe connection. After the initial processing of the pipe joints is completed, they need to be polished by a polishing device.

[0003] Although the existing device can grind the inner wall, outer wall and edge of the pipe joint, different grinding blocks need to be used and multiple grindings need to be performed, resulting in low grinding efficiency. Utility Model Content

[0004] In order to solve the above technical problems at least to a certain extent, the utility model provides a pipeline joint grinding device.

[0005] The purpose and effect of the pipe joint grinding device of the utility model are achieved by the following specific technical means:

[0006] A pipeline joint grinding device comprises a base; a grinding component is welded on the top surface of the base.

[0007] Furthermore, the grinding assembly includes a connecting block, a sliding protrusion, a first mounting block, a second mounting block, a first motor, a clamp, a mounting arm, a locking screw, a first threaded rod, a second motor, a grinding block and a second threaded rod, two connecting blocks of rectangular block structures are welded on the top surface of the base, two sliding protrusions are welded on the top surface of the base, the first mounting block and the second mounting block slide together on the two sliding protrusions, and the first mounting block and the second mounting block are both rectangular block structures.

[0008] Furthermore, a first motor is fixed on the left end face of the first mounting block, the output shaft of the first motor passes through the first mounting block, a clamp is fixed on the output shaft of the first motor, and a pipe joint is clamped on the clamp; a mounting arm is welded on the top end face of the first mounting block, a locking screw is threadedly connected to the mounting arm, and the lower end of the locking screw is inserted into the circular socket on the outer wall of the clamp.

[0009] Furthermore, a first threaded rod is threadedly connected to one of the connecting blocks on the left side, and a right end of the first threaded rod is rotated on the left end surface of the first mounting block.

[0010] Furthermore, a second motor is fixed on the right end face of the second mounting block, and the output shaft of the second motor passes through the second mounting block. A grinding block is fixed on the output shaft of the second motor, and the grinding block is plugged into the pipe joint. At this time, the inner wall and the outer wall of the pipe joint are in contact with the grinding block.

[0011] Furthermore, the right side of the inner wall of the grinding block is an arc-shaped structure.

[0012] Furthermore, a second threaded rod is threadedly connected to one of the right connecting blocks, and a left end of the second threaded rod is rotated on the second mounting block.

[0013] Furthermore, a switch box is fixed on the top surface of the base, the switch box is electrically connected to the external power supply, the switch box is electrically connected to the first motor and the second motor, and a switch for starting and shutting down the first motor and the second motor is installed on the switch box.

[0014] Furthermore, two support blocks are symmetrically welded on the bottom end surface of the base, both of which are rectangular block structures, and both of which are in contact with the workbench.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the present application, through the provision of the grinding block, on the one hand, because both the inner wall and the outer wall of the pipe joint are in contact with the grinding block, the inner and outer walls of the pipe joint can be grinded simultaneously, thereby improving the grinding efficiency; on the other hand, because the right side of the inner wall of the grinding block is an arc-shaped structure, when the pipe joint is in contact with the right side of the inner wall of the grinding block, the right side edge of the pipe joint can be polished through the arc-shaped part of the right side of the inner wall of the grinding block. Compared with the existing device, the present device can grind the inner wall, outer wall and edge of the pipe joint at the same time, and has a high grinding efficiency.

[0017] In the present application, through the provision of the first threaded rod, when the second threaded rod is damaged and cannot be adjusted, the first threaded rod can be rotated to drive the first mounting block to move to the right, thereby achieving a good emergency effect.

[0018] In the present application, the first motor and the clamp are arranged so that when the grinding efficiency needs to be improved, the locking screw is loosened and the switch on the switch box is pressed to control the first motor to rotate in the opposite direction. When the first motor rotates in the opposite direction, it can drive the pipe joint to rotate. At this time, since the pipe joint and the grinding block rotate in opposite directions, the grinding efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
