The construction pipe cutting and fixing device has a simple structure and a reasonable design. The slot formed by the movably connected left and right blocks can meet the placement of construction pipes of different diameters, and the construction pipes are pressure-fixed, which can prevent the construction pipes from jumping and flipping during the cutting process, making it convenient for operators to cut and ensuring the cutting effect.

[0004] In the above patent, although the pipe cutting and fixing device is convenient for operators to cut, when fixing the pipe, the outer wall of the pipe is clamped and fixed by an external clamp.

Subsequently, when the pipe is cut, the blade and the outer wall of the pipe will instantly contact and cause a certain impact force. At this time, it is very easy to cause the outer wall of the pipe to be concave and deformed, affecting the yield rate of the pipe cutting process. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the prior art, when fixing a pipe, the outer wall of the pipe is clamped and fixed by an external clamping block. Since the pipe is in a hollow state, a large pressure is applied to the pipe from the outer wall after the pipe is clamped. Subsequently, when the pipe is cut, a certain impact force is caused when the blade contacts the outer wall of the pipe for a moment, which easily causes the outer wall of the pipe to be concave and deformed, affecting the yield rate of the pipe cutting process. A pipe cutting and fixing device is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipe cutting and fixing device, comprising: a frame and a pipe body, the top of the frame is fixedly connected to a processing table, the top of the processing table is symmetrically fixedly connected to a support frame, and the top of the support frame is fixedly connected to a placement seat; a supporting assembly, the supporting assembly is fixedly connected to the top of the processing table, the supporting assembly includes a bracket, the outer surface of the bracket is fixedly connected to a first electric push rod, the end face of the first electric push rod is fixedly connected to a supporting bracket, the top of the supporting bracket is symmetrically fixedly connected to a second electric push rod, and the upper end face of the second electric push rod is fixedly connected to a supporting block; a positioning assembly, the positioning assembly is fixedly connected to the top of the processing table, and the positioning assembly includes a base frame.

[0011] Preferably, a second photoelectric switch is fixedly connected to the top of the base frame, and the second photoelectric switch is electrically connected to the hydraulic rod.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the pipe body is cut and processed, the second electric push rod is started to extend and drive the supporting block to move upward when the pipe body is clamped and fixed. After the supporting block moves upward, it fits the inner wall of the pipe body. The supporting blocks on both sides can be on both sides of the cutting position to support the inner wall of the pipe body. When the cutting machine is used to cut the pipe body, the cutting machine blade will cut the pipe body from the position between the two sides of the supporting block. Since the supporting block supports the inner walls on both sides of the cutting position, when the outer wall of the pipe body contacts the cutting machine blade and is subjected to force, it can avoid the outer wall of the pipe body from being dented when it is subjected to instantaneous impact force, thereby effectively improving the yield rate of pipe cutting.

[0014] 2. In the utility model, after the pipe body is placed on the placement seat, the second photoelectric switch is blocked, indicating that the workpiece is in place.

[0023] The effect achieved by the entire embodiment 1 is that when the pipe body 3 is cut, the pipe body 3 is inserted from the right side of the processing table 2, so that the cutting of the pipe body 3 is located between the top frames 8 on both sides. After the pipe body 3 is placed on the placement seat 7, the hydraulic rod 9 is started to extend to drive the clamping plate 11 to move down, and the pipe body 3 is clamped between the clamping plate 11 and the placement seat 7 to complete the fixation. Then, according to the cutting position of the pipe body 3, the first electric push rod 402 is started to extend to move the support frame 403 to the cutting position of the inner wall of the pipe body 3. When the pipe body 3 is clamped and fixed, the second electric push rod 404 is started to extend to drive the support block 405 to move up. After the support block 405 moves up, it fits the inner wall of the pipe body 3, and the support blocks 405 on both sides are 05 can be on both sides of the cutting position to support the inner wall of the tube body 3. When the cutting machine is used to cut the tube body 3, the cutting machine blade will cut the tube body 3 from the position between the two sides of the supporting block 405.

[0025] The effect achieved by the entire embodiment 2 is that when the tube body 3 is cut and placed on the placement seat 7, the tube body 3 will block the photoelectric signal emitted by the second photoelectric switch 502 at the bottom. When the second photoelectric switch 502 is blocked, it means that the workpiece is in place. The second photoelectric switch 502 can control the hydraulic rod 9 to extend and clamp the tube body 3, thereby achieving the purpose of automatically positioning the workpiece and completing the clamping and fixing, and improving the degree of automation of the device.

[0026] Working principle: When cutting the pipe body 3, insert the pipe body 3 from the right side of the processing table 2, start the hydraulic rod 9 to extend and drive the clamping plate 11 to move down, clamp the pipe body 3 between the clamping plate 11 and the placement seat 7 to complete the fixation, start the first electric push rod 402 to extend and move the support frame 403 to the cutting position of the inner wall of the pipe body 3, when the pipe body 3 is clamped and fixed, start the second electric push rod 404 to extend and drive the support block 405 to move up to fit the inner wall of the pipe body 3, so as to support the inner wall of the pipe body 3. When the cutting machine is used to cut the pipe body 3, the cutting machine blade will move from both sides of the support block 405. The pipe body 3 is cut through at the position between the two ends. Since the supporting blocks 405 play a supporting role on both sides of the cutting position, when the outer wall of the pipe body 3 contacts and is subjected to force by the cutting machine blade, it can avoid the outer wall of the pipe body 3 from being dented when subjected to instantaneous impact force. When the pipe body 3 is cut, the pipe body 3 will block the photoelectric signal emitted by the second photoelectric switch 502 at the bottom. When the second photoelectric switch 502 is blocked, it indicates that the workpiece is in place. The second photoelectric switch 502 can control the hydraulic rod 9 to run and extend to clamp and fix the pipe body 3, thereby achieving the purpose of automatically positioning the workpiece for placement and completing clamping and fixing, and improving the degree of automation of the device.
