DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0020] Combine the following Figures 1 to 6 The invention describes a disc-shaped pipe positioning and cutting device and a cutting method thereof.

[0021] like Figure 1 and Figure 2 As shown, in one embodiment, a disc-shaped pipe positioning and cutting device includes a plurality of limit plates 300, a plurality of adjustment frames 400, a plurality of clamping members 500, a plurality of connecting members 600 and a cutting device; the plurality of limit plates 300 are all mounted on a fixing frame 200, the central axes of the plurality of limit plates 300 coincide, and the limit plates 300 can rotate around their own central axes at a set angle; the plurality of adjustment frames 400 are arranged in a circular array and are plugged into the limit plates 300 along the radial direction of the limit plates 300, and the adjusting members are arranged in a circular array and are plugged into the limit plates 300 along the radial direction of the limit plates 300. The end is located at the inner circle of the limiting plate 300; multiple clamping members 500 are respectively fixed to one end of the inner circle of the limiting plate 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 plate 300, and the cutting device can move longitudinally and cut the pipe to be cut in the limiting plate 300.

[0022] Before using the above-mentioned disc-shaped pipe positioning and cutting device, the adjustment frame 400 is adjusted according to the pipe diameter. 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 the high-speed rotation, and the cutting of the pipe is completed. During the cutting process, the limit plate 300 is reciprocated at a set angle, which 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.

[0023] 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.

[0024] 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 penetrated and fixed on the first fixing rod and the second fixing rod. A pair of transverse rods 220 is arranged between each pair of transverse rods 220, and the four transverse rods 220 are equidistant from each other.

[0025] 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, most of the iron filings generated by the cutting equipment when cutting the pipe will 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.

[0026] like Figure 4As 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 mutually nested manner, and the two are connected by a plurality of connecting portions 330 arranged in an annular 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 an annular array and penetrate the inner annular plate 320.

[0027] 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 obliquely above the outer annular plate 310 , and a spacing groove 360 ​​is formed between two adjacent handles 350 .

[0028] 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 casting or injection molding, so the structure of the limiting plate 300 can be regarded as a circular ring member with a plurality of through openings in an annular array on the end surface.

[0029] 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 plugged into the two through holes 340, one end of the two plug-in rods 410 is connected by the connecting rod 420, the support rod 430 is arranged in the middle of the connecting rod 420, and the direction is the same as the plug-in direction of the plug-in rod 410, and the spring 440 is sleeved on the support rod 430.

[0030] Specifically, the support rod 430 is rotatably mounted on the connecting rod 420 and is threadedly connected to the connecting rod 420 . One end of the spring 440 away from the outer annular plate 310 is always located at the middle section of the support rod 430 .

[0031] The support rod 430 can be rotated according to actual use 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.

[0032] 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.

[0033] 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 openings formed by bending the 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 .

[0034] In one embodiment, a disc-shaped pipe positioning and cutting device, applied to the disc-shaped pipe positioning and cutting device of any of the above embodiments, comprises the following steps: The adjusting frame is adjusted to widen the pipe insertion path of the inner circle of the limit plate.

[0035] The pipeline is inserted into the pipeline plug-in path formed by the multiple clamping members, and the adjusting member is adjusted so that the multiple clamping members clamp the pipeline.

[0036] 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 pipeline to be cut is moved to just below the cutting device.

[0037] 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.

[0038] The above-mentioned disc-shaped pipe positioning and cutting method, before use, adjusts the adjustment frame according to the pipe diameter. During the adjustment process of the adjustment frame, the distance between the multiple clamping members will change, thereby widening the pipe plug-in path of the inner circle of the limit plate; at this time, the pipe can be inserted into the pipe plug-in path formed by the multiple clamping members, and the adjustment member is adjusted so that the multiple clamping members clamp the pipe; because the cutting device is located directly above the device, it is necessary to adjust the position of the limit plate 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 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 is reciprocated at a set angle. This operation can effectively prevent the burrs generated 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.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
