DETAILED DESCRIPTION

[0025] 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. Obviously, the embodiments described 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 are within the scope of protection of the present invention.

[0026] Example

[0027] Depend on Figure 1-6A pipe clamping device for laser cutting is provided, comprising a workbench 1, an adjusting mechanism 2 for pipe clamping is installed at the bottom of the workbench 1, a pushing mechanism 3 for pushing the pipe cutting is installed on the workbench 1, and limit blocks 5 are installed at the four corners of the upper surface of the workbench 1, and two groups are arranged in a bilaterally symmetrical manner. The two groups of limit blocks 5 are movably connected to telescopic rods 7, and the opposite sides of the two groups of telescopic rods 7 are fixedly connected to positioning plates 8 and located between the two groups of limit blocks 5;

[0028] The adjustment mechanism 2 includes a fixed plate 201, which is fixedly mounted on the lower surface of the workbench 1. Two bilaterally symmetrical C-shaped plates 203 are mounted on the fixed plate 201. The bottoms of the two C-shaped plates 203 are fixedly connected to rotating columns 204. The lower surface of the workbench 1 is also provided with an adjustment plate 206, on which two rotating columns 204 are mounted. Opposite sides of the two C-shaped plates 203 are respectively fixedly connected to opposite sides of the two positioning plates 8.

[0029] The pushing mechanism 3 includes a threaded rod 301, which is rotatably connected to the workbench 1. A sliding block 303 is installed on the outer wall of the threaded rod 301 and its upper surface is flush with the upper surface of the workbench 1. A reciprocating motor 302 is installed on the front of the workbench 1. The front of the threaded rod 301 passes through the interior of the workbench 1 and is fixedly connected to the output end of the reciprocating motor 302. A support plate 304 is installed on the upper surface of the sliding block 303, and a pushing plate 305 is installed at the center of the front of the support plate 304.

[0030] In this embodiment, the opening and closing of the two positioning plates 8 are controlled by the setting adjustment mechanism 2, thereby fixing the pipe placed on the workbench 1. After the fixation of the pipe is completed, the fixed pipe is pushed by the setting pushing mechanism 3. At the same time, rollers 11 are installed on the opposite sides of the two positioning plates 8, and the clamped pipe moves backward along the roller 11. The rolling rod 12 provided on the workbench 1 provides support for the moving pipe. At the same time, the rolling of the rolling rod 12 reduces the friction of the pipe on the workbench 1, so that the pipe moves more smoothly and avoids scratches caused by the friction between the pipe and the workbench 1.

[0031] Specifically, refer to Figure 2-3 The front and rear sides of the fixed plate 201 are provided with sliding grooves 202 for the two C-shaped plates 203 to slide and are slidably connected thereto.

[0032] In this embodiment, the two C-shaped plates 203 can be installed on the fixed plate 201 by the provided sliding grooves 202 , thereby realizing the movement of the two C-shaped plates 203 on the fixed plate 201 .

[0033] Specifically, refer to Figure 2-3A rotating plate 205 is rotatably connected between the two rotating columns 204 on the opposite side, and a double-headed cylinder 207 is fixedly installed on the bottom of the workbench 1 and its output end is fixedly connected to the front of the adjustment plate 206.

[0034] In this embodiment, a rotating plate 205 is rotatably connected between two rotating columns 204 on opposite sides, so that when the double-headed cylinder 207 pushes the adjusting plate 206 to move backward, the two rotating plates 205 rotate with the rotating column 204 on the adjusting plate 206 as the center of the circle, thereby realizing the "eight"-shaped opening and closing of the two rotating plates 205, thereby controlling the movement of the two C-shaped plates 203 on the fixed plate 201.

[0035] Specifically, refer to Figure 1-5 The upper surface of the workbench 1 is provided with a positioning groove 4 for the threaded rod 301 to rotate, and the sliding block 303 is adapted to the positioning groove 4 and is slidably connected thereto.

[0036] In this embodiment, the positioning groove 4 is set to enable the threaded rod 301 to rotate in the positioning groove 4. At the same time, the sliding block 303 is adapted to the positioning groove 4 and is slidably connected thereto, so that the sliding block 303 can move back and forth in the positioning groove 4. Then, the sliding block 303 is threadedly connected to the outer wall of the threaded rod 301, so that the rotation of the threaded rod 301 can be adjusted to control the movement of the sliding block 303 in the positioning groove 4.

[0037] Specifically, refer to Figure 1-5 , the pushing plate 305 is located on the lower surface of the two positioning plates 8.

[0038] In this embodiment, the push plate 305 is located on the lower surface of the two positioning plates 8, so that the lower surface of the two positioning plates 8 is separated from the upper surface of the workbench 1 by a certain distance, so that the push plate 305 is not restricted by the positioning plates 8 and can move back and forth on the workbench 1. At the same time, the length of the push plate 305 is less than the distance between the two sets of limit blocks 5, thereby avoiding the two sets of limit blocks 5 restricting the movement of the push plate 305 and making it unable to move back and forth.

[0039] Specifically, refer to Figure 4-5 The limit block 5 is provided with a telescopic hole 6 for sliding the telescopic rod 7, which is slidably connected to the limit block 5. The length of the telescopic rod 7 is greater than the maximum distance the two positioning plates 8 move when opening and closing.

[0040] In this embodiment, the telescopic hole 6 is set to enable the telescopic rod 7 to move on the limit block 5, and then the telescopic rod 7 is set to enable the positioning plate 8 to form a movable air distance with the workbench 1 with the limit block 5 as the support. At the same time, the opening and closing of the two positioning plates 8 are controlled by the movement of the two groups of telescopic rods 7 on the limit block 5, and the length of the telescopic rod 7 is set to be greater than the maximum distance moved when the two positioning plates 8 are opened and closed, so as to avoid the telescopic rod 7 being too short, which causes the two positioning plates 8 to fall off from the limit block 5 when closed, thereby failing to fix the pipe.

[0041] Specifically, refer to Figure 5-6 A plurality of rotating grooves 9 are provided on opposite sides of the two positioning plates 8, and mounting holes 10 are provided on the upper and lower inner walls of the rotating grooves 9. The rotating grooves 9 are rotatably connected with rollers 11 whose number matches the rotating grooves 9 through the mounting holes 10.

[0042] In this embodiment, the roller 11 installed inside is able to rotate through the provided rotating groove 9, and the roller 11 is installed in the rotating groove 9 through the provided mounting hole 10. After the two positioning plates 8 move in the same direction to fix the pipe, the fixed pipe is pushed by the provided pushing mechanism 3, so that the roller 11 rolls synchronously when the pipe moves, so that the pipe moves more smoothly under the action of the roller 11, and at the same time, direct contact between the two positioning plates 8 when fixing the pipe is avoided, and traces of friction produced during pushing are avoided.

[0043] Specifically, refer to Figure 1-5 The workbench 1 is rotatably connected to a rolling rod 12 and is located behind the two positioning plates 8 . The support plate 304 and the rolling rod 12 are at the same height on the upper surface of the workbench 1 .

[0044] In this embodiment, the pipe is transported by cooperating with the rollers 11 on the two positioning plates 8 to reduce the impact of marks caused by friction on the left and right sides and bottom of the pipe on the pipe. At the same time, the support plate 304 is set to be consistent with the height of the rolling rod 12 on the upper surface of the workbench 1, so that they are maintained at the same horizontal height to prevent the height difference from affecting the effect of the pipe cutting and failing to meet the cutting requirements.

[0045] Working principle:

[0046] The pipe clamping device for laser cutting of the present invention: first, start the double-headed cylinder 207, so that the double-headed cylinder 207 drives the adjusting plate 206 to shrink and move synchronously. At this time, the two rotating plates 205 on the adjusting plate 206 are closed in an "eight" shape, thereby controlling the same-direction movement of the two C-shaped plates 203 on the fixed plate 201, thereby closing the two positioning plates 8 on the upper workbench 1, so that the two positioning plates 8 can fix the pipes placed on the support plate 304 and the rolling rod 12, and then start the reciprocating motor 302 to drive the threaded rod 301 to rotate so that the sliding block 303 threadedly connected thereto moves, thereby realizing the movement of the support plate 304 and the pushing plate 305, so that the pushing plate 305 pushes the fixed pipe to move along the rollers 11 provided on the positioning plates 8 on both sides and the rolling rod 12 installed on the workbench 1, thereby performing laser cutting on the pipe, so as to achieve the purpose of reducing manual intervention and fixing the pipe to be cut while pushing it.
