Description

[0001] The utility model relates to the technical field of clamps, in particular to a pipeline clamp. Background Art

[0002] After using the metal pipe fittings on mechanical equipment for a period of time, not only the outer surface is prone to rust, but also the inside is prone to rust. Therefore, the inner wall of the metal pipe needs to be polished and rusted. In order to facilitate the polishing of the inside of the metal pipe, a clamp is used to clamp the metal pipe for stable processing.

[0003] At present, the method for grinding the inside of a metal pipe is mostly to use a first cylinder to push a clamping device to clamp the metal pipe, and then use an internal grinding device to grind the inner wall of the metal pipe.

Therefore, we propose a pipe clamp to solve the above problem. Utility Model Content

[0028] Example

[0029] Reference Figure 1-Figure 6The utility model provides a technical solution: a pipe clamp, including a processing plate 1 and a clamp mechanism 3, the upper surface of the processing plate 1 is fixed with a mounting frame 2, the clamp mechanism 3 includes an electric telescopic rod 31, the electric telescopic rod 31 is fixedly mounted on the upper surface of the processing plate 1, the telescopic end of the electric telescopic rod 31 is rotatably connected to a connecting rod 311, a clamping block 32 is fixedly mounted on one end of the connecting rod 311, the upper surface of the processing plate 1 is fixedly connected to a positioning frame 331, the interior of the positioning frame 331 is slidably connected to a support rod 332, one side of the support rod 332 is fixedly connected to a first cylinder 33, and the telescopic end of the first cylinder 33 corresponds to the position of the clamping block 32.

[0030] In a preferred embodiment, the telescopic end of the electric telescopic rod 31 is fixedly connected to the rectangular block 4, and one side of the rectangular block 4 is rotatably connected to the connecting rod 311. A rectangular groove 5 is provided at the bottom of the connecting rod 311, and a movable block 6 is arranged inside the rectangular groove 5. In order to facilitate the control of the rotation of the connecting rod 311, the device fixes the rectangular block 4 at the telescopic end of the electric telescopic rod 31, and rotatably installs the connecting rod 311 on one side of the rectangular block 4, so as to control the rotation of the connecting rod 311, thereby adjusting the position of the clamping block 32.

[0031] In a preferred embodiment, the upper surface of the processing plate 1 is rotatably connected to the damping rod 7, and one end of the damping rod 7 is rotatably connected to the moving block 6. In order to make the connecting rod 311 rotate normally and be positioned at a certain position, the damping rod 7 is installed on the upper surface of the processing plate 1, and the telescopic end of the damping rod 7 is rotatably connected to the connecting rod 311, so that the connecting rod 311 is positioned at a certain position, thereby adjusting the clamping block 32 to a suitable position and clamping the workpiece.

[0032] In a preferred embodiment, a groove is provided on the top of the positioning frame 331, and the interior of the groove is slidably connected to the support rod 332. The first cylinder 33 is fixedly installed at the upper end of the support rod 332. The support rod 332 is arranged above the connecting rod 311. In order to lift the clamping block 32 to stably clamp the workpiece, a slidable support rod 332 is installed inside the positioning frame 331. By rotating the connecting rod 311 and pushing the connecting rod 311 to move, the position of the support rod 332 is adjusted, so that the telescopic end of the first cylinder 33 can squeeze the clamping block 32, so that the clamping block 32 can stably clamp the workpiece.

[0033] The device performs clamping processing on the metal pipe. In order to avoid the outer surface of the metal pipe being clamped, the clamping block 32 is set to an arc shape. Two clamping blocks 32 are set. The inner side surface of each clamping block 32 is fixedly connected to a rubber pad. By installing the rubber pad on the inner side surface of the clamping block 32, the outer surface of the pipe can be prevented from being clamped.

[0034] In order to facilitate the grinding of the inside of the metal pipe and keep the inside of the metal pipe clean, the device installs a grinding mechanism 8 on the mounting frame 2. The grinding mechanism 8 includes a driving motor 81, a grinding head 82 and a pressure sensor 83. The upper surface of the processing plate 1 is fixedly connected to the placement plate 9. The pressure sensor 83 is fixedly installed inside the placement plate 9. The top of the pressure sensor 83 is installed with an extrusion plate 10. The pressure sensor 83 is electrically connected to the PLC controller 11. The top of the mounting frame 2 is fixedly connected to the second cylinder 12. The telescopic end of the second cylinder 12 is fixedly connected to the disc 13. The bottom of the disc 13 is fixedly connected to the second cylinder 12. The mounting frame 2 is fixedly connected to a driving motor 81, and the output end of the driving motor 81 is fixedly connected to a grinding head 82. A sliding groove 14 is provided on one side of the mounting frame 2, and a sliding block is arranged inside the sliding groove 14. The sliding block is fixedly connected to the disc 13 through a connecting rod 15. In actual use, a second cylinder 12 is installed on the mounting frame 2, and a driving motor 81 is installed at the telescopic end of the second cylinder 12. The grinding head 82 is driven to rotate by the driving motor 81, so that the inside of the workpiece can be polished conveniently. At the same time, a pressure sensor 83 is installed inside the placing plate 9 to facilitate automatic clamping of the workpiece so as to process the workpiece.

[0035] Specifically, the working process or working principle of a pipe clamp is as follows: currently, the method for grinding the inside of a metal pipe is mostly to use a first cylinder 33 to push a clamping device to clamp the metal pipe, and then use an internal grinding device to grind the inner wall of the metal pipe.

[0036] However, due to the different lengths of metal pipes, in current use, only a fixed position of the metal pipe can be clamped. For longer metal pipes, if the clamping position is in a lower center position, when the grinding equipment is used to grind the inside of the metal pipe, the upper end of the metal pipe is likely to shake, affecting the grinding effect on the inside of the metal pipe. Therefore, the present device is designed to solve this problem. An external power supply is connected, the workpiece is placed on the upper surface of the extrusion plate 10, and the extrusion plate 10 is squeezed so that the extrusion plate 10 generates an extrusion force on the pressure sensor 83, and the electric telescopic rod 31 is controlled by the PLC controller 11 to work, and the telescopic end of the electric telescopic rod 31 is extended to push the clamping block 32 to move. Since the telescopic end of the electric telescopic rod 31 is in an extended state, one end of the connecting rod 311 will rotate upward, and under the limit of the damping rod 7, the clamping block 32 will be stably maintained at a certain position. The present device can select the clamping position of the clamping block 32 for the workpiece according to the length of the workpiece to avoid shaking of the upper end of the workpiece during grinding.

[0037] When one end of the connecting rod 311 rotates upward, it will push the support rod 332 to move upward, which can push the first cylinder 33 to move, so that the telescopic end of the first cylinder 33 is always consistent with the position of the clamping block 32. After determining the position of the clamping block 32, the first cylinder 33 is opened, and the clamping block 32 is squeezed by the telescopic end of the first cylinder 33 to position the clamping block 32. The clamping block 32 can be stably clamped by the clamping block 32, which facilitates stable processing of the workpiece.

[0038] Then, the second cylinder 12 is turned on, and the driving motor 81 is controlled to move downward by the second cylinder 12. At the same time, the driving motor 81 is turned on, and the grinding head 82 is driven to rotate by the driving motor 81, so that the grinding head 82 can be extended into the interior of the workpiece to grind the workpiece to meet the use requirements.

[0039] It should be noted that the electric telescopic rod 31, the first cylinder 33, the drive motor 81, the pressure sensor 83, the PLC controller 11 and the second cylinder 12 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
