In addition, the second rotatable roller not only ensures the smooth rotation of the pipe during the processing, but also realizes the stable restriction of the position of the pipe, avoiding any adverse effect on the rotation process of the pipe.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-7 , the present invention provides a technical solution for steel pipe cutting equipment:

[0028] according to Figure 1-6 As shown, the steel pipe cutting equipment includes a swing arm 101, a cutting assembly 102, a cutting platform 103 and a pipe fitting 104. The swing arm 101 and the cutting platform 103 are rotatably mounted, and the cutting assembly 102 is mounted on the surface of the swing arm 101.

[0029] Among them, the grinding mechanism is arranged on the surface of the cutting platform 103, and the grinding mechanism includes a first motor 202 and a grinding roller 209. A sliding track 201 is fixedly connected to one side of the cutting platform 103, and a sliding connection seat 227 is slidably connected to the surface of the sliding track 201. The first motor 202 is fixedly installed on the surface of the sliding connection seat 227, and the grinding roller 209 is fixedly connected to the output shaft of the first motor 202. The grinding roller 209 is driven to rotate by the first motor 202, and the grinding roller 209 can achieve the effect of real-time grinding of the burrs and protrusions inside the pipe 104.

[0030] Among them, the driving rotation mechanism is arranged on the surface of the cutting platform 103, and the driving rotation mechanism includes three abutment plates 221, a second motor 224, a connecting bracket 213 and a driving wheel 225. Two hydraulic rods 204 are fixedly installed on one side of the cutting platform 103. The power output ends of the two hydraulic rods 204 are fixedly connected with a support plate 228. The hydraulic rods 204 can drive the rotating mechanism to enter the pipe 104. The upper end of the support plate 228 is fixedly connected with the insertion tube 203. The connecting bracket 213 and one end of the insertion tube 203 are fixedly connected. The ends are fixedly connected, and a group of support rods 219 are inserted into the three arms of the connecting bracket 213. The three abutment sheets 221 are respectively fixedly connected to one end of the three groups of support rods 219, and the other ends are fixedly connected with extrusion sheets 218. A sub-bracket 223 is fixedly sleeved on the surface of one of the support rods 219, and the second motor 224 is fixedly installed on the surface of the sub-bracket 223. The driving wheel 225 is fixedly connected to the output shaft of the second motor 224. The pipe fitting 104 can be driven to rotate through the driving wheel 225 to facilitate subsequent cutting and grinding operations.

[0031] Among them, the internal thread of the insertion tube 203 is inserted with a first screw rod 211, and the first screw rod 211 is rotated to drive the push block 217 to move between the three extrusion sheets 218. One end of the first screw rod 211 is fixedly connected to the second connecting shaft 216, and the other end is fixedly connected to the handle 210. A push block 217 is arranged between the three extrusion sheets 218. The push block 217 and the three extrusion sheets 218 are squeezed to push the first rollers 220 on the three abutment sheets 221 to fit tightly against the inner wall of the pipe fitting 104, so as to limit the position of the pipe fitting 104, so as to cooperate with the grinding roller 209, so that the grinding roller 209 fits against the inner wall of the pipe fitting 104 for cutting operation. The surface of the push block 217 is fixed. A first connecting shaft 215 is connected, and the first connecting shaft 215 and the second connecting shaft 216 are rotatably connected via a bearing 214. The surfaces of the three abutment plates 221 are rotatably connected to three first rollers 220. The first rollers 220 can limit the position of the pipe 104 without affecting the rotation of the pipe 104. A height limiting bracket 226 is fixedly connected to the surface of the cutting platform 103. The height limiting bracket 226 is located directly below the swing arm 101. When the swing arm 101 rotates downward, the swing arm 101 can be supported by the height limiting bracket 226, so as to limit the descending range of the cutting assembly 102 and prevent the cutting assembly 102 from descending too much and affecting the cutting of the pipe 104.

[0032] Among them, the surface of the cutting platform 103 is rotatably connected to a rotating shaft 207, the top of the rotating shaft 207 is fixedly connected to a gear 212, the upper end of the support plate 228 is fixedly connected to a second connecting frame 222, one end of the second connecting frame 222 is fixedly connected to a second rack 208, one end of the first motor 202 is fixedly connected to a first connecting frame 206, the surface of the first connecting frame 206 is fixedly connected to a first rack 205, the first rack 205 and the second rack 208 are both meshed with the gear 212, through the cooperation of the first rack 205, the second rack 208 and the gear 212, the grinding mechanism can be driven into the pipe 104 while driving the rotating mechanism to move.

[0033] When in use, after the pipe 104 to be cut is set at the designated position, the support plate 228 is driven to move by the hydraulic rod 204, so that the driving rotating mechanism enters the pipe 104, and the grinding mechanism can be driven to enter the pipe 104 while the driving rotating mechanism moves through the cooperation of the first rack 205, the second rack 208 and the gear 212, and then the handle 210 is held to drive the first screw 211 to rotate, so as to drive the push block 217 to move between the three extrusion sheets 218, and to generate extrusion with the inclined surfaces of the three extrusion sheets 218, so as to push the three abutment sheets 221 to move away from each other, so that the first roller 220 can be closely attached to the inner wall of the pipe 104;

[0034] Then the swing arm 101 drives the cutting assembly 102 having a power mechanism such as a motor and a saw blade to rotate downward to cut the pipe 104. The cutting assembly 102 is a common means in the prior art and will not be described in detail here. While cutting the pipe 104, the driving wheel 225 is driven to rotate by the second motor 224. Since the driving wheel 225 is made of rubber and fits the inner wall of the pipe 104, the pipe 104 can be driven to rotate when the driving wheel 225 rotates, so that the cutting of the pipe 104 is achieved through the cooperation of the cutting assembly 102. During the cutting process of the pipe 104, the grinding roller 209 is driven to rotate by the first motor 202. Since the grinding roller 209 is in close contact with the inner wall of the pipe 104, the burrs and protrusions inside the pipe 104 can be polished in real time as the pipe 104 is cut and rotated.

[0035] according to Figure 7As shown, the positioning mechanism is arranged on the surface of the cutting platform 103, and the positioning mechanism includes a movable clamping plate 302, a fixed clamping plate 305 and a second screw rod 307. The surface of the cutting platform 103 is fixedly connected with the positioning platform 301, the movable clamping plate 302 is slidably connected to the inner surface of the positioning platform 301, and the second screw rod 307 is inserted into the internal thread of the positioning platform 301. One end of the second screw rod 307 is rotatably connected to the movable clamping plate 302, and the pipe fitting 104 can be clamped with the movable clamping plate 302 through the second screw rod 307, and a rocker 306 is fixedly installed on the other end. The fixed clamping plate 305 is fixedly connected to the surface of the positioning platform 301, and the pipe fitting 104 is clamped by the fixed clamping plate 305 and the movable clamping plate 302, which can prevent the pipe fitting 104 from rolling and affecting the grinding mechanism and the driving rotating mechanism to insert into the pipe fitting 104.

[0036] Among them, the surfaces of the movable clamping plate 302 and the fixed clamping plate 305 are rotatably connected with multiple second rollers 304. The rotatable second rollers 304 can limit the position of the pipe 104 without affecting the rotation of the pipe 104. The upper ends of the movable clamping plate 302 and the fixed clamping plate 305 are fixedly connected with a clamping block 303, and the thickness of the clamping block 303 is higher than the height of the second roller 304 protruding from the movable clamping plate 302 and the fixed clamping plate 305.

[0037] During specific use, the pipe 104 is placed between the movable clamping plate 302 and the fixed clamping plate 305, and then the second screw rod 307 is driven to rotate through the rocker 306. When the second screw rod 307 rotates, it will clamp the pipe 104 with the movable clamping plate 302, so as to prevent the pipe 104 from rolling and affecting the grinding mechanism and the driving rotation mechanism to insert into the pipe 104, and the rotatable second roller 304 can limit the position of the pipe 104 without affecting the rotation of the pipe 104.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
