Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of pipe cutting, specifically relates to a pipe cutting device for water and electricity installation. BACKGROUND

[0002] At present, various pipes are often used in water and electricity installation, and the required pipe length is different, so it is necessary to cut the pipe to an appropriate length by using a cutting device for subsequent use.

[0003] The Chinese patent with the publication number CN113145928A discloses a pipe cutting system and a use method thereof, and the structure comprises a handle, a support plate, a cutting machine, a cutting piece and an adjustable cutting external hanging device. The utility model has the effect that the adjustable cutting external hanging device is composed of a left limiting adjustment frame, a movable measuring seat, an adjustment and movement front frame and a right limiting adjustment frame. The cutting machine can be stably moved on the top surface of the square pipe of different widths through the holding structure formed by the handle and the support plate under the action of the adjustment structure formed by the adjustable cutting external hanging device. The cutting machine automatically completes the cutting positioning of the cutting piece during the cutting process of the square pipe by using the cutting piece, so that the cutting surface of the square pipe formed after cutting remains flat. At the same time, the scale ruler always keeps parallel with the square pipe during movement, which can quickly cut the square pipe of the required length, thereby greatly improving the efficiency of the step-by-step equidistant cutting of the square pipe.

[0004] The existing cutting device usually has poor stability when cutting the pipe, which causes the pipe to easily displace during the cutting process, thereby affecting the cutting accuracy of the pipe. In addition, the cutting surface of the pipe after cutting usually has many burrs and is not smooth enough, so workers need to manually use sandpaper to polish the cutting surface in the later stage, which is time-consuming and laborious. Otherwise, the burrs can easily cause harm to workers during subsequent use. In addition, dust and debris will be generated during the cutting of the pipe, and part of the debris will remain on the surface of the cutting wheel. If not cleaned in time, the debris will affect the sharpness of the cutting wheel, thereby affecting the service life of the cutting wheel. In addition, a large amount of dust and debris will greatly reduce the environmental quality of the side of the pipe during cutting, which seriously affects the working environment of workers.

[0005] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

[0042] The utility model will be explained further in detail in combination with the drawings.

[0043] Please refer to Figures 1-7 As shown in the drawings, in the embodiment, a pipe cutter for water and electricity installation is provided, which comprises a bottom plate 1, first electric guide rails 2 are arranged on the left and right sides of the upper side of the bottom plate 1, supports 3 are slidably connected to the upper sides of the two first electric guide rails 2, fixed frames 4 are fixedly arranged on the front and rear sides of the upper side of the bottom plate 1, circular plates 5 are fixedly arranged on the upper ends of the fixed frames 4, four clamping plates 9 are elastically fixed to the inner sides of the circular plates 5, clamping assemblies are arranged on one side of the circular plates 5 and fixed to the four clamping plates 9, and positioning assemblies are drivingly connected to the clamping assemblies and arranged on the circumferential sides of the circular plates 5.

[0044] The lower side of the horizontal section of the support 3 is provided with a second electric guide rail 16, the lower side of the second electric guide rail 16 is slidably connected to an air cylinder 17 and a rotary motor 22, the lower side of the air cylinder 17 is provided with an air rod 18, the lower end of the air rod 18 is provided with a cutting wheel 19, the circumferential side of the cutting wheel 19 is provided with two rubber layers 21, the output end of the rotary motor 22 is fixedly connected to a polishing wheel 23, the circumferential side of the rotary motor 22 is fixedly connected to a cleaning brush 24 corresponding to the circumferential side of the polishing wheel 23, a collection box 25 is fixedly arranged on the middle of the upper side of the bottom plate 1, a dust collector is arranged in the collection box 25, and a suction port 26 is arranged on the upper middle of the collection box 25.

[0045] It should be noted that all the electrical equipment involved in the present application can be powered by a storage battery or an external power source.

[0046] As Figure 1As shown, the clamping assembly of this embodiment includes four push plates 8 fixed to one end of four clamping plates 9, four plates 6 slidably fitted to one side of a circular plate 5, four L-shaped plates 7 rotatably fitted between the ends of two adjacent plates 6, a drive plate 10 fixed to one side of one of the plates 6, and a push rod 12 fixed to one side of the drive plate 10. The four push plates 8 are located between the four plates 6, and the four push plates 8 are slidably fitted to the inner side of the four plates 6. The two ends of the L-shaped plates 7 are rotatably fitted to the ends of two adjacent plates 6, and the bent part of the L-shaped plates 7 is rotatably fitted to one side of the circular plate 5.

[0047] First, manually push the push rod 12, causing the push rod 12 to drive the drive plate 10 to move in an arc shape inward and upward. This causes the drive plate 10 to move one of its plates 6 in sync. Then, the plate 6 moves one end of its L-shaped plate 7. Since the bend of the L-shaped plate 7 rotates and engages with one side of the circular plate 5, the other end of the L-shaped plate 7 will move the other plate 6 in sync. The other two plates 6 perform the above movements in sequence, so that the four plates 6 move inward in the same direction, causing the four plates 6 to press against the four push plates 8. Then, the four push plates 8 drive the four clamping plates 9 to move closer to each other and clamp and fix the periphery of the pipe, thus completing the stable clamping of pipes of different diameters.

[0048] like Figures 2-3 As shown, the positioning assembly of this embodiment includes an arc-shaped track 11 fixed to the periphery of the circular plate 5, an arc-shaped plate 14 fixed to the upper center of the arc-shaped track 11, a circular locking plate 13 elastically slidably engaged with the lower inner side of the arc-shaped plate 14, and a pull rod 15 fixed to the upper center of the circular locking plate 13. A through groove is provided in the upper center of the arc-shaped plate 14, and the upper end of the pull rod 15 is slidably engaged in the through groove. Pushing the push rod 12 causes it to slide within the arc-shaped track 11, thereby moving the drive plate 10. Then, when the push rod 12 moves to the appropriate position, the pull rod 15 is released, and the pull rod 15 causes the circular locking plate 13 to elastically rebound, causing the circular locking plate 13 to engage with the push rod 12, thereby fixing the push rod 12 in place.

[0049] like Figures 2-3 As shown, in this embodiment, a first spring is fixed between the lower inner side of the arc-shaped plate 14 and the upper side of the circular clamping plate 13. The push rod 12 corresponds to the circular clamping plate 13, and a second spring is fixed between the inner side of the circular plate 5 and the outer side of the clamping plate 9. When the pull rod 15 is manually released, the elastic rebound force of the first spring will cause the circular clamping plate 13 to engage with the push rod 12. When the clamping plate 9 clamps and fixes the pipe, the elastic rebound force of the second spring will cause the clamping plate 9 to fit more tightly against the periphery of the pipe.

[0050] like Figure 4As shown, the opposite sides of the cylinder 17 of the embodiment are fixed with connecting rods 20, two rubber layers 21 are respectively fixed with the lower ends of the two connecting rods 20, and a through hole is arranged between the two rubber layers 21. A rectangular groove is arranged above the two rubber layers 21, the lower half of the cutting wheel 19 is located in the rectangular groove, and the lower side of the two rubber layers 21 corresponds to the suction port 26.

In the process of rotating, the rectangular groove scrapes the surface of the cutting wheel 19, so that the waste is left in the two rubber layers 21, and the waste in the two rubber layers 21 is adsorbed and collected through the suction port 26. And because the two rubber layers 21 are elastic and deformable materials, the through hole can be extruded and deformed according to the size of the pipe.

[0051] As Figure 5 shown, the polishing wheel 23 of the embodiment is located on one side of the cutting wheel 19, and the polishing wheel 23 and the cutting wheel 19 are located above the suction port 26. First, the pipe is cut by the cutting wheel 19, and then the cutting surface of the pipe is polished by the polishing wheel 23 after cutting is completed, and the waste generated in the process of cutting and polishing is adsorbed and collected through the suction port 26.

[0053] Step one: first, place the pipe to be cut between the four clamping plates 9 in the middle of the two circular plates 5, then push the clamping assembly so that the clamping assembly drives the four clamping plates 9 to relatively approach and clamp and fix the circumferential side of the pipe, at this time, loosen the positioning assembly to position the clamping assembly after adjustment;

[0054] Step two: then start the first electric guide rail 2, so that the first electric guide rail 2 drives the support 3 to move to the position where the pipe needs to be cut, then start the second electric guide rail 16, so that the second electric guide rail 16 drives the cylinder 17 and the rotating motor 22 to move left and right synchronously, moves the polishing wheel 23 to the position directly above the pipe, and the two rubber layers 21 are attached to the upper side of the suction port 26, and the pipe is located between the two rubber layers 21;

[0055] Step three: start the cylinder 17, the output end of the cylinder 17 drives the air rod 18 to extend, then the air rod 18 drives the cutting wheel 19 to descend to cut the pipe, start the dust collector in the process of cutting, the dust collector adsorbs and collects the waste generated during cutting through the suction port 26, after cutting is completed, the air rod 18 drives the cutting wheel 19 to ascend, and the two rubber layers 21 above scrape the waste on the surface of the cutting wheel 19 in the process of ascending.

[0056] Step four: after cutting, the second electric guide rail 16 is started again, the second electric guide rail 16 drives the cylinder 17 and the rotating motor 22 to move synchronously left and right, at this time the polishing wheel 23 is located at the cutting end of the pipe, then the rotating motor 22 is started, the output end of the rotating motor 22 drives the polishing wheel 23 to polish the cutting surface of the pipe quickly, the cleaning brush 24 cleans the periphery of the polishing wheel 23 during polishing, and the dust collector collects the waste generated during polishing through the suction port 26.
