[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a cutting device for processing a smooth pipe comprises: a cutting box 1, the upper inner wall of the cutting box 1 is fixedly connected with a downward pressing cutting device 2, one side end of the cutting box 1 is fixedly connected with a pushing seat 5, and the inner wall of the cutting box 1 is provided with a debris collection box 6; a rotating mechanism 3, which is used to fix the pipe and rotate it to cooperate with the downward pressing cutting device 2 for cutting, and the rotating mechanism 3 is arranged on one side of the pushing seat 5; an auxiliary supporting mechanism 4, which is used to assist in fixing the pipe and is arranged on the inner side of the cutting box 1; wherein the rotating mechanism 3 comprises a fixing component 301 arranged on the upper side of the pushing seat 5, and a limiting component 302 and a locking component 303 are arranged on one side of the fixing component 301, and the cutting box 1 has an opening door for convenient maintenance of the device in the cutting box 1, and an observation window is embedded in the opening door. For the staff in this technical field, the cutting box 1 is a prior art and will not be described in detail here. The pushing seat 5 The hydraulic push rod can control the distance from the cutting box 1, so that the fixing component 301 can be used to fix the cutting box 1 and adjust the cutting position. When the device is used to cut the pipe, the pipe is fixed by the fixing component 301, and the limit component 302 makes the fixing component 301 more stable. The locking component 303 makes the fixing of the pipe by the fixing component 301 not easy to loosen, and then the pipe is assisted to be fixed by the auxiliary support mechanism 4. At this time, the downward cutting device 2 is started, and the pipe is pressed down to contact and cut at the same time. Then the fixing component 301 is started to drive the pipe to rotate slowly, so that the circumference of the pipe contacts the downward cutting device 2 in turn for cutting, which greatly reduces the downward pressing depth of the saw blade and reduces wear. The downward cutting device 2 includes a cutting part dust suction pipe and a downward pressing device. For the staff in this technical field, the downward pressing cutting device 2 and the pushing seat 5 are both prior art and will not be elaborated here.

[0024] like Figure 2 and Figure 3As shown, the fixing assembly 301 includes a first mounting plate 3011 fixedly connected to the upper end of the pushing seat 5, one side end of the first mounting plate 3011 is fixedly connected to the first motor 3012, the output end of the first motor 3012 is fixedly connected to a "C"-shaped plate 3013, the circumferential inner wall of the "C"-shaped plate 3013 is rotatably connected to a bidirectional lead screw 3014, the surface of the bidirectional lead screw 3014 is threadedly connected to two pushing nuts 3015, the upper and lower ends of the two pushing nuts 3015 are movably hinged with connecting rods 3016, the upper and lower sides of the bidirectional lead screw 3014 are provided with fitting blocks 3017, the two fitting blocks 3017 are respectively movably hinged to one end of the plurality of connecting rods 3016, the bidirectional lead screw 3014 itself has a certain thread angle, and has It has a certain self-locking ability. When the pipeline needs to be fixed, the pipeline is sleeved on the surface of the fitting block 3017, and then the bidirectional lead screw 3014 is rotated. The surface of the bidirectional lead screw 3014 has two threads in opposite directions, so the bidirectional lead screw 3014 pushes the two pushing nuts 3015 close to each other, and the two pushing nuts 3015 pull the two connecting rods 3016 to deflect at an angle and bulge. The connecting rods 3016 push the fitting block 3017 to fit the inside of the pipeline for fixation. The fitting block 3017 has a friction pad at one end close to the pipeline to increase the friction during connection. When the pipeline is fixed, the first motor 3012 is started at this time, and the "C"-shaped plate 3013 drives the pipeline to rotate slowly, and contacts the downward pressing cutting device 2 in turn for cutting. For those working in the technical field, the first motor 3012 is prior art and will not be described in detail here. The limiting assembly 302 includes a second mounting plate 3024 fixed to one side end of the "C"-shaped plate 3013, one side end of the second mounting plate 3024 is fixedly connected to a rotating seat 3023, and the bidirectional lead screw 3014 is rotatably connected to the inner wall of the rotating seat 3023. When the bidirectional lead screw 3014 rotates, the bidirectional lead screw 3014 is prone to swing. The bidirectional lead screw 3014 rotates on the inner wall of the rotating seat 3023, so that the bidirectional lead screw 3014 is not prone to swing when it rotates. A dovetail groove 3021 is provided on one side end of the second mounting plate 3024 close to the rotating seat 3023, and one side end of the two push nuts 3015 are fixedly connected to dovetail grooves.

The locking assembly 303 includes a spur gear 3031 fixedly connected to the circumferential surface of the two-way screw 3014, and the inner wall of the "C"-shaped plate 3013 is fixedly connected to a mounting block 3034, and one side end of the mounting block 3034 is fixedly connected to a spring 3033, and one end of the spring 3033 is fixedly connected to a tooth block 3032.The tooth block 3032 fits closely with the surface of the spur gear 3031. When the bidirectional lead screw 3014 pushes the fitting block 3017 to fit inside the pipe, it may be reversed and loosened if fixed for a long time. The spring 3033 pushes the tooth block 3032 to fit the surface of the spur gear 3031, so that the spur gear 3031 and the bidirectional lead screw 3014 are not easy to rotate by themselves. One side end of the tooth block 3032 is fixedly connected with a pull rod 3035. One end of the pull rod 3035 movably passes through one side end of the mounting block 3034 and extends outward. The spring 3033 is sleeved on the circumferential surface of the pull rod 3035. The tooth block 3032 can be adjusted by the pull rod 3035. Pull it away from the spur gear 3031 for explanation. At the same time, the pull rod 3035 can support the spring 3033 to prevent the spring 3033 from being damaged due to elastic deformation. The inner wall of the two-way lead screw 3014 is fixedly connected with a mounting seat 3037. The inner wall of the mounting seat 3037 is slidably connected with a fixing seat 3038. One end of the pull rod 3035 is fixedly connected with a fixing block 3036. The inner wall of the fixing seat 3038 is relatively close to the fixing block 3036. When the pipeline is fixed by the locking assembly 303, it is necessary to continuously pull the push nut 3015 so that the tooth block 3032 and the spur gear 3031 are no longer in contact to unlock, which is quite troublesome. At this time, after pulling the push nut 3015, the fixing seat 3038 is in contact with the surface of the fixing block 3036 to fix the pull rod 3035 and the fixing block 3036, so that the tooth block 3032 will not reset and contact the spur gear 3031. The fixing assembly 301 can adjust the fixed pipeline at will.

For the staff in this technical field, the second hydraulic push rod 405 and the first hydraulic push rod 401 are both prior art and will not be elaborated on here.

[0026] When the utility model is in use, when the device is used to cut the pipeline, the pipeline is sleeved on the surface of the fitting block 3017, the fixing block 3036 is pulled, and the fixing block 3036 is fixed by the fixing seat 3038. At this time, the spur gear 3031 and the tooth block 3032 are separated, and then the two-way screw 3014 is rotated, so that the two-way screw 3014 brings the two pushing nuts 3015 closer to each other, and the two pushing nuts 3015 pull the two connecting rods 3016 to bulge, and the connecting rods 3016 push the fitting block 3017 to fit the inside of the pipeline for fixing, and at this time, the fixing seat 3038 is pulled up, so that the spring 303 The tooth block 3032 is pushed to fit the surface of the spur gear 3031, the rotation of the bidirectional lead screw 3014 is locked, and then the cutting position is adjusted by the push seat 5. The first hydraulic push rod 401 and the second hydraulic push rod 405 push the two groups of lower fitting seats 403 to fit the circumferential surface of the pipe for auxiliary fixation. At this time, by starting the first motor 3012, the "C"-shaped plate 3013 drives the pipe to rotate slowly, and the circumference of the pipe contacts the downward cutting device 2 in turn for cutting, and the debris is collected by the downward cutting device 2 and the debris collection box 6, which greatly reduces the downward pressing depth of the saw blade, reduces the wear of the pipe and the saw blade, and makes the pipe cut smoother.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
