DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As shown in the figure, the present utility model discloses a pipe clamping and cutting device, the purpose of which is to position and quickly and accurately cut pipes at the infrastructure construction site, which can reduce the cutting cost and the equipment configuration cost of the construction party.

[0024] The embodiments of the technical solution disclosed by the present utility model are described as follows:

[0025] Embodiment 1: A pipe clamping and cutting device, as shown in the attached drawings, includes a platform 1. Four support legs 11 are arranged at the four corners of the bottom of the platform 1, and the platform 1 can be set off the ground through the four support legs 11.

[0026] A cylinder 2 is arranged at the bottom of the platform 1. A top pressure swing arm 21 and a side pressure swing arm 25 are respectively arranged at both ends of the cylinder 2. Avoidance grooves 12 vertically penetrating are respectively arranged on the platform 1 corresponding to the top pressure swing arm 21 and the side pressure swing arm 25, and the top pressure swing arm 21 and the side pressure swing arm 25 vertically penetrate the avoidance grooves 12. A hinge point is arranged on the platform 1 for the side pressure swing arm 25 to be hinged. An L-shaped hinge column 13 is arranged on the top pressure swing arm 21. The top pressure swing arm 21 is hingedly arranged at the top of the hinge column 13 through a top pressure hinge shaft 22. The top of the top pressure swing arm 21 is a horizontally arranged top rod 23. A top extrusion block 23 is horizontally hingedly arranged at the bottom of the top rod 23. The part of the top extrusion block 23 in contact with the pipe 8 is made of rubber or plastic. A side extrusion block 26 is hingedly arranged on the side pressure swing arm 25. The part of the side extrusion block 26 in contact with the pipe 8 is made of rubber or plastic. Since the present utility model is applicable to the cutting of plastic pipes, PVC pipes and metal pipes with relatively thin wall thicknesses, when positioning the pipe, the above flexible materials are used to squeeze and contact the pipe 8 to avoid causing extrusion scars or damaging the pipe 8. The above structure can clamp the pipe at the top and side under the drive of the cylinder 2.

[0027] Further, on the top surface of the platform 1, a bottom surface positioning block 5 is arranged between the top pressure swing arm 21 and the side pressure swing arm 25; a pipe placement groove 51 is arranged on the bottom surface positioning block 5, and its shape matches the outer diameter of the pipe 8 for fixing the bottom of the pipe 8. A side adjustment groove 52 is also arranged on the bottom surface positioning block 5. A side baffle 53 is arranged in the side adjustment groove 52, and the user can adjust the left and right of the side baffle 53, which cooperates with the side extrusion block 26 to clamp the pipe 8 on the left and right sides.

[0028] The utility model also provides a fixing pile 6 on the top surface of the platform 1. A bearing 61 is fixed on the fixing pile 6. Those skilled in the art can replace it with a bushing assembly, and the effects are equivalent. In this embodiment, a rotating member 62 is connected to the periphery of the bearing. A hand saw fixing frame 65 is arranged on the rotating member 62. The hand saw 7 is fixed through the hand saw fixing frame 65. In this embodiment, as Figure 4 shown, the fixing surface of the hand saw fixing frame 65 is L-shaped. This design can cooperate with the reserved nut holes on the hand saw 7

[0029] to fix the hand saw 7 on both side surfaces simultaneously, effectively improving the locking strength and avoiding the loosening of the hand saw during sawing.

[0030] The utility model also provides a tension spring 63 between the rotating member 62 and the platform 1 for use as an elastic reset member. After the hand saw 7 rotates and presses down to saw the pipe material 8 through the saw blade 71, the entire saw fixing frame 65 together with the hand saw 7 can be rotated and reset under the pulling of the tension spring 63. A rotation positioning member 64 is arranged between the rotating member 62 and the fixing pile 6 or the platform 1. In this embodiment, a rotation positioning member 64 is welded and arranged on the top of the fixing pile 6. The rotation positioning member 64 is arranged at the rear side of the saw fixing frame 65. When the saw fixing frame 65 rotates and resets, it stops rotating after touching the rotation positioning member 64.

[0031] The above structure can realize the manual sawing after the pipe material 8 is clamped, and at the same time, it can also realize the automatic reset of the saw fixing frame 65 together with the hand saw 7, and can realize continuous and stable sawing actions.

[0032] The utility model also provides a tail rod 3 on the platform 1. A scale is arranged on the tail rod 3 or a scale ruler 31 is directly inlaid and fixed. An adjusting block 32 is also arranged on the tail rod 3. A locking knob 33 is arranged on the adjusting block 32 to realize the locking and positioning after the movement of the adjusting block 32.

[0033] A longitudinal movement positioning block 34 is arranged on the adjusting block 32. A longitudinal movement sliding groove is arranged in the longitudinal movement positioning block 34. The baffle slider 35 and the baffle 36 are longitudinally fixed through the longitudinal movement sliding groove. Through this structural arrangement, the accurate measurement of the length of the pipe material 8 can be realized, so as to realize the fixed-length sawing of the pipe material 8.

[0034] Embodiment 2: Through the structural description of Embodiment 1, the utility model realizes the length determination, clamping, and sawing of the pipe material 8 with a relatively simple structure. However, during the actual sawing operation, since the components on the right side of the saw blade 71 are fixed, after the pipe material is sawed, the saw blade 71 will be clamped between the pipe materials 8. Also, because the power of the electric hand saw 7 used in the utility model is usually not large, this state of clamping the saw blade 71 by the pipe material is likely to cause an increase in the cutting power of the electric hand saw 7 or even damage. To avoid the occurrence of the above problems, the utility model further improves the structure as follows: A reset tension spring 39 is arranged between the baffle 36 and the adjusting block 32, and a steel cable 41 is fixed on the baffle 36. The other end of the steel cable 41 is connected to the steel cable fixing point 66 on the electric hand saw fixing frame 65. The operating principle of the above structure is: When operating the control to press down the electric hand saw 7 for sawing, it drives the steel cable 41 to pull the baffle 36. When the sawing is completed, the electric hand saw 7 is pressed down to the bottom. At this time, the steel cable 41 pulls the baffle 36 to the maximum extent, and the baffle 36 disengages from the axial extrusion of the pipe material 8, which can reduce the axial thrust of the sawn pipe material 8 on the saw blade 71 to a certain extent. At this time, the saw blade 71 will not bear a large extrusion force.

[0035] After the above structural improvement, it is possible to reduce the pressure on the saw blade 71. However, after sawing, the pipe material 8 is still pressed above the bottom positioning block 5, and at this time, the saw blade 71 still receives a certain axial extrusion force. Therefore, to completely improve the above problems, the utility model further improves as follows: On the platform 1, an adjustment groove 14 is provided directly below the electric hand saw 7, and the cylinder controller or sensor is fixed through the adjustment groove 14. When the electric hand saw 7 is pressed down, it can touch the cylinder controller or sensor to relax the clamping action. The cylinder controller or sensor described here is connected to the cylinder air valve. This connection principle of the controller or sensor is common in the mechanical field, and those skilled in the art can make the structural connection under the guidance of the above description, and no detailed description will be made here.

[0036] Embodiment 3: During the operation of Embodiment 1 and Embodiment 2 described above, the steel cable 41 for pulling the baffle 36 is an exposed structure, and this exposure poses a safety hazard. To avoid this problem, the utility model provides a conduit 4 and a stop bolt assembly around the steel cable 41. The stop bolt assembly includes an adjusting block stop bolt plate 37, an end plate 38 at the end of the adjusting block stop bolt plate 37, and a stop bolt nut I 381 on the end plate 38. It also includes a stop bolt nut II 641 on the rotation positioning member 64. The conduit 4 is fixed between the stop bolt nut I 381 and the stop bolt nut II 641. This structure realizes the fixation of the conduit 4 and can avoid affecting external personnel or devices.

[0037] In summary, the structure of the utility model is novel and easy to manufacture, and can realize rapid and continuous cutting of PVC pipe materials and thin metal pipe materials at the construction site, which improves the working efficiency and ensures the cutting accuracy. It is an ideal pipe material clamping and cutting device.
