Butt welding machine with a cutter for a plastic pipe comprising a drive gear unit

A butt welding machine (2) adjusting the ends of plastic pipes and welding them to each other comprising a cutter (1) having a driving element (16) for moving a trimmer (13) by being driven, also comprising at least one movable claw (24, 32, 33) to hold pipes which will be positioned, wherein the at least one movable claw (24, 32, 33) is attached to an upper bearing shaft (25) from one end of each and to a lower bearing shaft (30) from another end of each and also attached to a side bearing shaft (28) from another end of each, for bearing the at least one movable claw (24, 32, 33) for making axial movement,

• the butt welding machine (2) is characterized by a motor (21) which does not have direct connection with the cutter (1) and transfers power to the cutter (1) and to the at least one movable claw (24 and/or 32 and/or 33) via at least one driving shaft (23, 29, 31), the butt welding machine (2) also characterized by a drive gear unit (22) which provides energy to the at least one movable claw (24 and/or 32 and/or 33) and cutter (1) so which drives different driving shafts (23, 29, 31) of the at least one movable claw (24 and/or 32 and/or 33) and the cutter (1) synchronously wherein the cutter (1) and the at least one movable claw (24 and/or 32 and/or 33) need two different driving motions,
• wherein the cutter (1) is connected to a cutter driving shaft (29) for connecting the cutter (1) with the drive gear unit (22) and so transmitting a motion energy which it receives from the drive gear unit (22) to the driving element (16) for driving the cutter (1) rotationally,
• and wherein the at least one movable claw (24 32, 33) is attached to a lower driving shaft (31) and an upper driving shaft (23) connecting the at least one movable claw (24, 32, 33) with the drive gear unit (22) and transmitting a motion energy that it receives from the drive gear unit (22) to the at least one movable claw (24, 32, 33) driving the at least one movable claw (24, 32, 33) for moving at a direction of the horizontal axis of the machine (2),
• wherein all driving shafts (23, 29, 31) are connected from one of their ends to the drive gear unit (22) for transmitting motion energy.
