DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The following combination Figures 1 to 6 The present invention describes a disc-shaped pipe positioning and cutting device and a cutting method thereof.

[0036] like Figure 1 and Figure 2As shown, in one embodiment, a disc-shaped pipe positioning and cutting device includes multiple limit plates 300, multiple adjustment frames 400, multiple clamping members 500, multiple connecting members 600 and a cutting device; multiple limit plates 300 are mounted on a fixed frame 200, the central axes of the multiple limit plates 300 coincide, and the limit plates 300 can rotate around their own central axes at a set angle; multiple adjustment frames 400 are arranged in a ring array and are inserted into the limit plates 300 along the radial direction of the limit plates 300. The adjustment frames 400 are arranged in a ring array and are inserted into the limit plates 300 along the radial direction of the limit plates 300. 0 is located at the inner ring of the limiting disk 300; multiple clamping members 500 are respectively fixed to one end of the inner ring of the limiting disk 300 of multiple adjustment frames 400, and the inner surface of the clamping member 500 is used to fit the pipe to be cut; multiple connecting members 600 are respectively arranged between two adjacent clamping members 500, and the two ends of the connecting member 600 are respectively movably clamped in the two clamping members 500; the cutting device is arranged above the limiting disk 300, and the cutting device can move longitudinally and cut the pipe to be cut in the limiting disk 300.

[0037] The above-mentioned disc-shaped pipe positioning and cutting device is adjusted to the adjustment frame 400 according to the pipe diameter before use. During the adjustment process of the adjustment frame 400, the distance between the multiple clamping members 500 will change, thereby widening the pipe plug-in path of the inner circle of the limit plate 300; at this time, the pipe can be inserted into the pipe plug-in path formed by the multiple clamping members 500, and the adjustment member is adjusted so that the multiple clamping members 500 clamp the pipe; since the cutting device is located directly above the device, it is necessary to adjust the position of the limit plate 300 according to the position of the cutting device, so that the limit plate 300 moves along the length direction of the fixed frame 200, and the position of the pipe to be cut is moved directly below the cutting device; then the cutting device is started so that the cutting blade of the cutting device gradually moves downward during high-speed rotation, and the cutting of the pipe is completed. During the cutting process, the limit plate 300 is rotated back and forth at a set angle. This operation can effectively prevent the burrs on the surface of the pipe from drifting to the same side. After the cutting is completed, there is basically no need for laborious manual cleaning, and it is relatively convenient to use.

[0038] like Figure 3 As shown, in one embodiment, the fixing frame 200 is arranged on the fixing base 100, and the fixing base 100 includes a first fixing plate 110, a second fixing plate 120 and a bending plate 130; the bending plate 130 is located directly above the first fixing plate 110, and the bottom end of the bending plate 130 abuts against the first fixing plate 110, and the two second fixing plates 120 are respectively located on both sides of the bending plate 130, and one side end of the second fixing plate 120 is connected to one side end of the bending plate 130.

[0039] Specifically, the fixing frame 200 includes two pairs of longitudinal rods 210 and two pairs of transverse rods 220. The two pairs of longitudinal rods 210 are vertically passed through and fixed on the first fixing plate 110 and the second fixing plate 120. A pair of transverse rods 220 is arranged between each pair of longitudinal rods 210, and the four transverse rods 220 are equidistant from each other.

[0040] Among them, if a virtual line segment is connected between the four adjacent transverse rods 220, the virtual line segments between the four transverse rods 220 can form a square. In addition, since the bending plate 130 is located in the middle position, the iron filings generated by the cutting equipment when cutting the pipe will mostly fall on the surface of the second fixed plate 120 and eventually gather and slide onto the bending plate 130, which is more convenient for subsequent cleaning.

[0041] like Figure 4 As shown, in one embodiment, the limit plate 300 includes an outer annular plate 310, an inner annular plate 320 and a connecting portion 330; the outer annular plate 310 and the inner annular plate 320 are arranged in a circular array, and the two are connected by a plurality of connecting portions 330 arranged in a circular array, and a plurality of pairs of through holes 340 are provided on the outer annular plate 310, and the plurality of pairs of through holes 340 are arranged in a circular array and pass through the inner annular plate 320.

[0042] Among them, a long curved hole is formed between every two connecting parts 330 and the outer annular plate 310 and the inner annular plate 320, and the four transverse rods 220 are respectively inserted into the four long curved holes, and the transverse rods 220 can move in the long curved holes around the array center of the four long curved holes.

[0043] Specifically, two pairs of handles 350 are fixed on the surface of the outer annular plate 310 . The two pairs of handles 350 are respectively located on both sides of the upper side of the outer annular plate 310 , and a spacing groove 360 ​​is formed between two adjacent handles 350 .

[0044] Among them, the outer annular plate 310, the inner annular plate 320 and the connecting portion 330 can be integrally formed, that is, produced by a method such as casting or injection molding, so the structure of the limiting plate 300 can be regarded as a circular member with a plurality of through openings opened in an annular array on the end surface.

[0045] like Figure 5 Shown and Figure 6 As shown, in one embodiment, the adjustment frame 400 includes a plug-in rod 410, a connecting rod 420, a support rod 430 and a spring 440; the two plug-in rods 410 are respectively inserted into the two through holes 340, and one end of the two plug-in rods 410 is connected by the connecting rod 420, and the support rod 430 is arranged in the middle of the connecting rod 420, and its direction is the same as that of the plug-in rod 410, and the spring 440 is sleeved on the support rod 430.

[0046] Specifically, the support rod 430 is rotatably mounted on the connecting rod 420 and is threadedly connected to the connecting rod 420 . The end of the spring 440 away from the outer annular plate 310 is always located in the middle of the support rod 430 .

[0047] The support rod 430 can be rotated according to actual usage needs to adjust the distance between the support rod 430 and the outer ring plate 310. Since one end of the spring 440 is always located in the middle section of the support rod 430, the rotation adjustment of the support rod 430 can change the pressure or tension between the spring 440 and the outer ring plate 310, thereby adapting to the clamping of the pipeline.

[0048] In one embodiment, the clamping member 500 includes an outer folding plate 510 and an inner folding plate 520; the surfaces of the outer folding plate 510 and the inner folding plate 520 are both arc-shaped, and both ends of the outer folding plate 510 and the inner folding plate 520 are bent, and the bending directions are opposite.

[0049] Specifically, the connecting member 600 includes a bent plate 610 and a clamping plate 620; both ends of the bent plate 610 are respectively inserted into the openings formed by the bent ends of the outer folding plate 510 and the inner folding plate 520, and the two clamping plates 620 are respectively fixed at both ends of the bent plate 610.

[0050] In one embodiment, a method for positioning and cutting a disc-shaped pipe is applied to the disc-shaped pipe positioning and cutting device of any of the above embodiments, comprising the following steps:

[0051] Adjust the adjustment frame to widen the pipe insertion path of the inner circle of the limit plate.

[0052] Insert the pipeline into the pipeline plug-in path formed by the multiple clamping members, and adjust the adjusting member so that the multiple clamping members clamp the pipeline.

[0053] The position of the limit plate is adjusted according to the position of the cutting device, so that the limit plate moves along the length direction of the fixed frame, and the position of the pipe to be cut is moved to just below the cutting device.

[0054] The cutting device is started so that the cutting blade of the cutting device gradually moves downward during high-speed rotation and completes the cutting of the pipe. During the cutting process, the limit plate is rotated at a set angle to effectively avoid the accumulation of cutting burrs.

[0055] The disc-shaped pipeline positioning and cutting method adjusts the adjusting frame according to the pipeline diameter before use, the distance between the plurality of clamping pieces changes during the adjusting process, so that the pipeline insertion path of the inner ring of the limiting disc is widened; at this time, the pipeline can be inserted into the pipeline insertion path formed by the plurality of clamping pieces, and the adjusting piece is adjusted to clamp the pipeline by the plurality of clamping pieces; since the cutting equipment is located directly above the device, the position of the limiting disc needs to be adjusted according to the position of the cutting equipment, so that the limiting disc moves along the length direction of the fixing frame, and the pipeline to be cut is moved to be directly below the cutting equipment; then the cutting equipment is started to gradually move downward during high-speed rotation of the cutting blade of the cutting equipment, and the cutting of the pipeline is completed; the limiting disc is set to reciprocatingly rotate at an angle during the cutting process, which can effectively prevent the burrs generated on the surface of the pipeline from floating to the same side, and basically no laborious manual cleaning is required after cutting, and the use is convenient.
