Description

Technical Field

[0002] As a common construction structure, fences are constructed with a variety of materials such as wood, metal, and plastic. Their main functions are to divide areas, limit access, ensure safety, and enhance landscape effects.

[0003] In the construction of fences, pillars play a vital supporting role. They are generally made of square or round pipes, and their size is carefully designed according to the overall height, stability and load-bearing requirements of the fence. For example, for heavy metal fences used in large commercial or industrial sites, the pillars often need to be buried deep underground and have a large diameter or cross-sectional area to ensure that they can effectively resist strong wind pressure and other external impacts and maintain long-term stability. Compared with high-specification fences, the size of the pillars for residential gardens or light fences can be appropriately reduced according to actual needs.

[0004] However, in the current construction process, the cutting of fence posts mostly relies on manual cutting. Although the manual cutting method is flexible, it is difficult to ensure the precise consistency of each cutting, especially when dealing with a variety of different length specifications. Workers need to frequently measure and cut and adjust, which poses a high risk of miscutting. Utility Model Content

[0030] Exemplarily, during the implementation process, a cutting area 3 is provided on the upper end surface of the base 1 , and the cutting area 3 corresponds to the cutting position of the cutting mechanism 16 , and is used to cooperate with the cutting mechanism 16 to perform precise cutting.

[0031] A first slide groove 2 is provided on the upper end surface of the base 1. The first slide groove 2 is located on one side of the cutting area 3 and extends in a direction perpendicular to the cutting area 3. The limit plate 4 is slidably arranged in the first slide groove 2, that is, the limit plate 4 can approach or move away from the cutting area 3 along the first slide groove 2.

[0032] The first threaded rod 5 is inserted into the first slide groove 2, and the first threaded rod 5 is rotatably connected to the groove wall of the first slide groove 2 through a shaft hole, a shaft bearing, and other connection methods. A threaded hole is provided at the lower end of the limit plate 4, and the first threaded rod 5 is screwed into the threaded hole of the limit plate 4. The first threaded rod 5 is rotated clockwise from the end of the first threaded rod 5 away from the cutting area 3, and the limit plate 4 gradually approaches the cutting area 3 along the first slide groove 2 under the action of the threaded transmission of the first threaded rod 5 and the limiting of the first slide groove 2.

[0033] The first clamping mechanism 6 includes a first clamping arm 61, a second clamping arm 62 and a first driving member 63. The first clamping arm 61 and the second clamping arm 62 are both arranged on the side of the cutting area 3 away from the first chute 2, and the first clamping arm 61 and the second clamping arm 62 are relatively arranged on both sides of the first chute 2. A first clamping channel is formed between the sides where the first clamping arm 61 and the second clamping arm 62 are close to each other, and the first clamping channel is used to clamp the pipe. The first driving member 63 is connected to the first clamping arm 61 and the second clamping arm 62, and the first driving member 63 can drive the first clamping arm 61 and the second clamping arm 62 to move closer to each other or away from each other to adjust the size of the first clamping channel.

[0034] When cutting pipe fittings, first, according to the required cutting length of the pipe fittings, the first threaded rod 5 is rotated clockwise, so that the limiting plate 4 gradually approaches the cutting area 3 under the action of the threaded transmission of the first threaded rod 5 and the limiting of the first slide groove 2, or the first threaded rod 5 is rotated counterclockwise, so that the limiting plate 4 gradually moves away from the cutting area 3 under the action of the threaded transmission of the first threaded rod 5 and the limiting of the first slide groove 2. Until the distance between the limiting plate 4 and the cutting area 3 is equal to the required cutting length of the pipe fittings.

When the pipe to be cut abuts against the limit plate 4, the first driving member 63 is operated to drive the first clamp arm 61 and the second clamp arm 62 to approach each other, so as to clamp the pipe to be cut in the first clamping channel between the first clamp arm 61 and the second clamp arm 62. On the one hand, the stability during the pipe cutting process is improved, thereby improving the precision of the pipe cutting. At the same time, the risk of displacement of the pipe is reduced during the cutting process, thereby enhancing the safety of the work. On the other hand, the first driving member 63 is used to drive the first clamp arm 61 and the second clamp arm 62 to approach or move away from each other to adjust the size of the first clamping channel. The purpose of being able to clamp pipes of different diameters between the first clamp arm 61 and the second clamp arm 62 is achieved.

[0036] Finally, the cutting mechanism 16 is operated to cut the pipe to be cut toward the cutting area 3 . After the cutting is completed, the required pipe can be obtained at a side of the cutting area 3 close to the first chute 2 .

[0037] After completing the cutting of the required pipe fittings once, operate the first driving member 63 to drive the first clamp arm 61 and the second clamp arm 62 away from each other to loosen the first clamp arm 61 and the second clamp arm 62. At this time, other pipe fittings to be cut can be replaced. Alternatively, the pipe fitting to be cut can be pushed toward the limit plate 4, and when the pipe fitting to be cut abuts against the limit plate 4 again, operate the first driving member 63 to drive the first clamp arm 61 and the second clamp arm 62 to approach each other, so as to clamp the pipe fitting to be cut in the first clamping channel between the first clamp arm 61 and the second clamp arm 62, so as to facilitate the cutting of the required pipe fittings again. On the one hand, the accuracy of each cutting is ensured during batch cutting, thereby improving the consistency of length between pipe fittings. On the other hand, the fixing and cutting at the preset position is achieved, effectively avoiding the cumbersome process of manual repeated measurement and adjustment. On the other hand, the error risk caused by manual operation is effectively reduced.

[0038] Example 2

[0039] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, in this embodiment, a second slide groove 7 is opened on the base 1, and the second slide groove 7 is located on the side of the cutting area 3 away from the first slide groove 2, and the extension direction of the second slide groove 7 is perpendicular to the extension direction of the first slide groove 2; the first clamping arm 61 is arranged on the base 1, and the first clamping arm 61 is located at one end of the second slide groove 7; the first driving member 63 includes a second threaded rod, the second threaded rod is passed through the second slide groove 7, and the second threaded rod is rotatably connected to the groove wall of the second slide groove 7; the second clamping arm 62 is slidably arranged in the second slide groove 7, and the second clamping arm 62 is screwed to the second threaded rod.

[0040] Exemplarily, during implementation, the base 1 is provided with a second slide groove 7, which is located on a side of the cutting area 3 away from the first slide groove 2, and the extension direction of the second slide groove 7 is perpendicular to the extension direction of the first slide groove 2. In other words, the second slide groove 7 extends in a direction parallel to the cutting area 3.

[0041] The first clamping arm 61 is disposed on the base 1 , and the first clamping arm 61 is located at one end of the second sliding groove 7 .

[0042] The first driving member 63 adopts a second threaded rod, which is inserted into the second slide groove 7 and is rotatably connected to the groove wall of the second slide groove 7. A threaded hole is provided at the lower end of the second clamping arm 62. The second threaded rod is screwed into the threaded hole at the lower end of the second clamping arm 62. The second threaded rod is rotated clockwise from the end of the second threaded rod away from the second slide groove 7, and the second clamping arm 62 gradually approaches the first clamping arm 61 along the second slide groove 7 under the action of the thread transmission of the second threaded rod and the limit of the second slide groove 7. The second threaded rod is rotated counterclockwise from the end of the second threaded rod away from the second slide groove 7, and the second clamping arm 62 gradually moves away from the first clamping arm 61 along the second slide groove 7 under the action of the thread transmission of the second threaded rod and the limit of the second slide groove 7.

[0043] The second threaded rod is rotated clockwise to drive the second clamping arm 62 to gradually approach the first clamping arm 61, so as to clamp the pipe to be cut in the first clamping channel between the first clamping arm 61 and the second clamping arm 62. The second threaded rod is rotated counterclockwise to drive the second clamping arm 62 to gradually move away from the first clamping arm 61, so as to loosen the first clamping arm 61 and the second clamping arm 62. On the one hand, the pipe can be quickly clamped and loosened, thereby greatly improving work efficiency and reducing manual labor intensity and operation difficulty. On the other hand, the second clamping arm 62 moves under the dual effects of thread transmission and slide groove limiting, which can not only ensure the stability and controllability of the clamping force, but also prevent shaking or deviation during the clamping process, thereby ensuring the stability of the pipe during the cutting process, thereby improving the cutting quality and safety.

[0044] Example 3

[0045] like Figure 1 As shown, based on the above-mentioned embodiment 2, in this embodiment, the two ends of the second threaded rod are respectively provided with forward threads and reverse threads; the first clamping arm 61 is slidably set in the second sliding groove 7; the first clamping arm 61 and the second clamping arm 62 are respectively screwed to the forward thread and reverse thread of the second threaded rod.

[0046] Exemplarily, in the implementation process, threads with different spiral directions are provided at both ends of the second threaded rod, for example, a forward thread is provided at one end of the second threaded rod, and a reverse thread is provided at the other end of the second threaded rod. The first clamp arm 61 is slidably provided in the second slide groove 7, and a threaded hole is provided at the lower end of the first clamp arm 61. The first clamp arm 61 and the second clamp arm 62 are respectively screwed to the forward thread and the reverse thread of the second threaded rod. For example, the first clamp arm 61 is screwed to the forward thread of the second threaded rod through the threaded hole, and the second clamp arm 62 is screwed to the reverse thread of the second threaded rod through the threaded hole; or, the first clamp arm 61 is screwed to the reverse thread of the second threaded rod through the threaded hole, and the second clamp arm 62 is screwed to the forward thread of the second threaded rod through the threaded hole.

[0047] The second threaded rod is rotated clockwise to drive the second clamping arm 62 and the first clamping arm 61 to move closer together under the action of the forward thread and the reverse thread, so as to clamp the pipe to be cut in the first clamping channel between the first clamping arm 61 and the second clamping arm 62. The second threaded rod is rotated counterclockwise to drive the second clamping arm 62 and the first clamping arm 61 to move away together under the action of the forward thread and the reverse thread, so as to release the first clamping arm 61 and the second clamping arm 62. The first clamping arm 61 and the second clamping arm 62 can act at the same time, shrink or expand synchronously, and realize fast and uniform clamping, without the need to adjust the two clamping arms separately, which greatly simplifies the operation process.

[0048] Example 4

[0049] like Figure 1 As shown, based on the above-mentioned embodiment 1, in this embodiment, a clamping groove 8 is provided on one side of the first clamping arm 61 close to the second clamping arm 62 ; the first clamping channel is formed between the clamping groove 8 and the second clamping arm 62 .

[0050] Exemplarily, during implementation, a clamping groove 8 is provided on one side of the first clamping arm 61 close to the second clamping arm 62 , and the clamping groove 8 and the second clamping arm 62 form a first clamping channel for clamping the pipe.

[0051] When the second threaded rod is rotated clockwise, the second clamp arm 62 and the first clamp arm 61 are synchronously approached under the action of the forward thread and the reverse thread, so that the gap between the clamp groove 8 and the second clamp arm 62 is reduced, and the pipe to be cut is pressed into the clamp groove 8 by the second clamp arm 62. At this time, the groove wall of the clamp groove 8 fits the outer wall of the pipe to be cut, so that the pipe to be cut is subjected to a more uniform and controllable clamping force. On the one hand, it can more effectively guide the pipe to be cut into and keep it in the correct position, effectively preventing the pipe from rolling or shifting during the clamping process. On the other hand, it helps to disperse the clamping force and avoid applying excessive local pressure directly on the outer wall of the pipe, thereby minimizing damage to the surface of the pipe while clamping.

[0052] Preferably, the first clamping arm 61 and the second clamping arm 62 have the same structure.

[0053] Example 5

[0054] like Figure 1 As shown, based on the above-mentioned embodiment 4, in this embodiment, a flexible pad 9 is provided on the groove wall of the clamping groove 8; the side of the flexible pad 9 away from the clamping groove 8 is used to fit on the outer wall of the pipe.

[0055] Exemplarily, during the implementation process, a flexible pad 9 is provided on the inner wall of the clamping groove 8, and the side of the flexible pad 9 away from the clamping groove 8 is used to fit on the outer wall of the pipe. The flexible pad 9 is made of a material with certain elasticity and wear resistance, such as rubber, silicone or other polymer composite materials, and can make a small adaptive deformation according to the outer diameter and shape of the pipe. During assembly, the flexible pad 9 is fixed to the inner wall of the clamping groove 8 by gluing, screwing, etc., to ensure that it can fit tightly on the outer wall of the pipe when clamping the pipe, so as to play a buffering and protective role.

[0056] When the first clamping arm 61 and the second clamping arm 62 clamp the pipe under the drive of the threaded rod, the flexible pad 9 can form a good contact with the surface of the pipe to ensure that the clamping force is evenly distributed on the entire contact surface. On the one hand, it can reduce the hard friction on the outer wall of the pipe during the clamping process to avoid damage caused by scratches or extrusion. On the other hand, it can increase the friction between the flexible pad 9 and the pipe, and effectively prevent the pipe from sliding during the cutting process even in the absence of a large clamping force, thereby improving the safety and accuracy of the cutting process. On the other hand, it can reduce the vibration generated during the cutting process from being transmitted to the pipe, further improving the cutting quality. At the same time, for pipes with slightly different sizes, the flexible pad 9 has a certain deformation ability, which can adapt to pipes of different diameters to a certain extent, thereby enhancing the versatility and flexibility of the clamping mechanism.

[0057] Example 6

[0058] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, in this embodiment, the pipe clamping mechanism also includes a second clamping mechanism 10; the second clamping mechanism 10 is arranged on the side of the cutting area 3 close to the first slide groove 2, the second clamping mechanism 10 includes a third clamping arm 101, a fourth clamping arm 102 and a second driving member 103, the third clamping arm 101 and the fourth clamping arm 102 are relatively arranged on both sides of the first slide groove 2, and a second clamping channel is formed between the third clamping arm 101 and the fourth clamping arm 102, and the second clamping channel is used to clamp the pipe; the second driving member 103 is arranged on the base 1, the second driving member 103 is connected to the third clamping arm 101 and the fourth clamping arm 102, and the second driving member 103 is used to drive the third clamping arm 101 and the fourth clamping arm 102 to move closer to or away from each other to adjust the size of the second clamping channel.

[0059] Exemplarily, during implementation, the pipe clamping mechanism further includes a second clamping mechanism 10 , and the second clamping mechanism 10 is disposed between the cutting area 3 and the first slide groove 2 .

[0060] The second clamping mechanism 10 includes a third clamping arm 101, a fourth clamping arm 102 and a second driving member 103. The third clamping arm 101 and the fourth clamping arm 102 are respectively located on both sides of the first slide groove 2 and are symmetrically arranged. A second clamping channel is formed between the sides where the third clamping arm 101 and the fourth clamping arm 102 are close to each other, and the second clamping channel is used to clamp the pipe. The second driving member 103 is connected to both the third clamping arm 101 and the fourth clamping arm 102, and the second driving member 103 can drive the third clamping arm 101 and the fourth clamping arm 102 to move closer to each other or away from each other to adjust the size of the second clamping channel.

[0061] The pipe to be cut is inserted into the first clamping channel and the second clamping channel, and the end of the pipe to be cut is abutted against the limit plate 4. When the pipe to be cut abuts against the limit plate 4, the first driving member 63 is operated to drive the first clamping arm 61 and the second clamping arm 62 to approach each other, so as to clamp the pipe to be cut in the first clamping channel between the first clamping arm 61 and the second clamping arm 62; at the same time, the second driving member 103 is operated to drive the third clamping arm 101 and the fourth clamping arm 102 to approach each other, so as to clamp the pipe to be cut in the second clamping channel between the third clamping arm 101 and the fourth clamping arm 102. On the one hand, the additional second clamping mechanism 10 allows the pipe to be firmly clamped from both ends at the same time during cutting, which can significantly improve the stability during the cutting process and reduce the cutting error caused by the swing of the pipe. On the other hand, the double clamping design can clamp the pipe from both ends during the cutting process to prevent the pipe from flying out due to uneven force, thereby enhancing work safety. On the other hand, after the required pipe is cut, the second clamping mechanism 10 is used to clamp the pipe, which can reduce the risk of the required pipe rolling and affecting the normal use of the pipe clamping structure.

[0062] Preferably, the second clamping mechanism 10 and the first clamping mechanism 6 adopt the same structure.

[0065] Exemplarily, during implementation, the positioning device is mainly used to fix the pipe clamping mechanism mentioned in the above embodiments, so that the pipe clamping mechanism can be moved and positioned.

[0066] The positioning device includes a connecting plate 11, a guide block 13 and a driving rod 14. Among them, a guide groove 12 is prefabricated on the connecting plate 11, and the guide block 13 is slidably arranged in the guide groove 12. The pipe clamping mechanism is connected to the base 1 by welding, screwing or integral molding, so that the base 1 can slide in the guide groove 12 following the guide block 13.

[0067] When the driving rod 14 is rotated, under the action of the threaded transmission and the limiting action of the guide groove 12, the guide block 13 will move along the guide groove 12, thereby driving the entire pipe clamping mechanism to perform precise positioning adjustment in the horizontal direction or vertical direction (depending on the direction of the guide groove 12). Through the cooperation of the guide groove 12 and the guide block 13, precise linear motion guidance of the clamping mechanism is achieved, ensuring that no deviation occurs during the adjustment or movement process, thereby improving the accuracy of the cutting position.
