Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an automatic pipe cutting machine. Background Art

[0002] Pipe fitting cutting is an operation of precisely cutting a pipe fitting to be cut according to a required length to meet the needs of various pipe fitting application scenarios.

[0003] Existing pipe cutting machines are usually ordinary circular saw blade cutting machines. During the cutting process, operators need to manually support the pipe fitting to be cut, and the pipe fitting may become loose during the cutting process, resulting in poor stability. Summary of the Invention

[0004] The purpose of the utility model is to provide an automatic pipe cutting machine with high stability and a compact structure in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] An automatic pipe cutting machine includes a frame and a cutting assembly connected to the frame. It is characterized in that it further includes a positioning assembly and a driving assembly. The positioning assembly is connected to the frame and is used for positioning the pipe fitting to be cut. The driving assembly is connected to the frame, and the cutting assembly is connected to the driving assembly. In the initial state, the cutting assembly is far away from the positioning assembly, and when the driving assembly operates, the cutting assembly can be made to enter the positioning assembly.

[0007] The automatic pipe cutting machine creatively positions the pipe fitting to be cut through the positioning assembly, and after the driving assembly operates, the cutting assembly is sent to the positioning assembly. Once the cutting assembly enters the positioning assembly, the positioned pipe fitting can be quickly and automatically cut by the cutting assembly.

[0008] It can be seen that since the pipe fitting to be cut is always positioned at the positioning assembly during the cutting process by the cutting assembly, the pipe fitting will not become loose during the cutting process, thus effectively improving the cutting quality and ensuring the operation stability.

[0009] In the above automatic pipe cutting machine, the positioning assembly includes a base, a fixed clamp, a movable clamp and a cylinder I. The base is connected to the upper part of the frame. The fixed clamp is fixedly connected to one side of the base. The movable clamp is connected to the other side of the base and is opposite to the fixed clamp. The cylinder I is fixedly connected to the base, and the piston rod of the cylinder I is fixedly connected to the movable clamp. When the cylinder I operates, the movable clamp can move back and forth relative to the fixed clamp.

[0010] The base provides enough space for connecting the fixed clamp, the movable clamp and the cylinder I. At the same time, the base can be conveniently connected to the frame, and finally, the fixed clamp, the movable clamp and the cylinder I can be conveniently and stably indirectly connected to the frame.

[0011] Since the movable clamp faces the fixed clamp, the movable clamp is away from the fixed clamp in the initial state. After the cylinder 1 drives the movable clamp to approach the fixed clamp, the pipe fitting to be cut can be stably positioned between the fixed clamp and the movable clamp.

[0012] In the above-mentioned automatic pipe cutting machine, the fixed clamp is provided with a first clamp body and a second clamp body. The first clamp body and the second clamp body are arranged front and back along the conveying direction of the pipe fitting, and there is a gap for avoiding the cutting component between the first clamp body and the second clamp body. The movable clamp is provided with a third clamp body and a fourth clamp body. The third clamp body faces the first clamp body, the fourth clamp body faces the second clamp body, and there is a gap for avoiding the cutting component between the third clamp body and the fourth clamp body.

[0013] Such a structure can increase the contact area between the fixed clamp, the movable clamp and the pipe fitting to be processed, and finally ensure that the pipe fitting to be processed is stably clamped.

[0014] In the above-mentioned automatic pipe cutting machine, the number of the positioning components is two, and the two positioning components are arranged front and back along the conveying direction of the pipe fitting.

[0015] Since both of the two positioning components are connected to the pipe fitting to be processed, the positioning stability of the pipe fitting to be processed can be effectively improved.

[0016] In the above-mentioned automatic pipe cutting machine, one of the positioning components is fixedly connected to the frame, and the other positioning component is movably connected to the frame.

[0017] Such a structure can adjust the distance between the two positioning components, so as to adapt to pipe fittings of different lengths.

[0018] In the above-mentioned automatic pipe cutting machine, a motor is fixedly connected to the base of the positioning component fixed on the frame. A lead screw is fixedly connected to the rotating shaft of the motor. The lead screw penetrates through the base of the other positioning component and is threadedly connected to the other positioning component.

[0019] During the process of the motor driving the lead screw to rotate, one of the positioning components will move smoothly relative to the other positioning component.

[0020] In the above-mentioned automatic pipe cutting machine, a guide rod is fixedly connected to the base of the positioning component fixed on the frame. The guide rod penetrates through the base of the other positioning component.

[0021] Under the action of the guide rod, the positioning component can move smoothly.

[0022] In the above-mentioned automatic pipe cutting machine, the number of the guide rods is two, and the two guide rods are symmetrically arranged on both sides of the lead screw.

[0023] The arrangement of the two guide rods can make the positioning component move more smoothly.

[0024] In the above-mentioned automatic pipe cutting machine, the cutting component includes a hinge seat, a second cylinder, a connecting rod and a circular saw blade cutting machine. The hinge seat is fixedly connected to the machine frame. The middle of the connecting rod is hinged to the upper part of the hinge seat. The cylinder body of the second cylinder is hinged to the machine frame, and the piston rod of the second cylinder is hinged to one end of the connecting rod. The circular saw blade cutting machine is fixedly connected to the other end of the connecting rod. After the second cylinder drives the connecting rod to swing, the circular saw blade cutting machine can swing to the positioning component.

[0025] In the initial state, the circular saw blade cutting machine is far away from the positioning component.

[0026] After the second cylinder drives the connecting rod to swing, since the circular saw blade cutting machine is connected to the connecting rod, the circular saw blade cutting machine can stably enter the positioning component after swinging with the connecting rod.

[0027] In the above-mentioned automatic pipe cutting machine, the connecting rod is V-shaped and the V-shaped opening of the connecting rod faces upward. The V-shaped angle of the connecting rod is hinged at the hinge seat.

[0028] Such a structure can keep the circular saw blade cutting machine as far away from the positioning component as possible, avoiding a relatively small swing stroke of the circular saw blade cutting machine.

[0029] Compared with the prior art, since this automatic pipe cutting machine has two positioning components, the pipe to be processed can be stably positioned. When the cutting component cuts the pipe to be processed, the cutting stability is relatively high.

[0030] At the same time, the position between the two positioning components can be adjusted. Therefore, it can process pipes of different lengths, and has high applicability.

[0031] In addition, since the positioning component can contact the pipe to be processed over a large area, the positioning stability of the pipe to be processed at the positioning component is high, further improving the overall stability of the machine, and having high practical value.
