Description

Technical Field

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

[0002] A pipeline is a device connected by pipes, fittings, and valves for transporting gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of uses, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] When cutting a pipe, a fixing plate is generally used to clamp the pipe directly. Since the outer wall of a circular pipe is an outer circular structure, the plate-shaped structure is used for fixing, which easily causes the outer wall of the pipe to be compressed and deformed. At the same time, when cutting a long pipe, one end of the pipe is left hanging and bent. The pipe will bend due to the force, which affects its subsequent use. Based on this, a processing clamping device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a processing clamping device, which effectively solves the deficiencies of the prior art.

[0005] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides a processing clamping device, including a base, a mounting bracket fixedly connected to one side of the top surface of the base, a fixing ring fixedly connected to one side, the outer wall of the fixing ring is rotatably connected to three first connecting rods and three second connecting rods in sequence, and the adjacent first connecting rods and second connecting rods form a group, three mounting seats are provided on one side of the fixing ring, and arc-shaped clamping blocks are provided inside the three mounting seats, one side of the three arc-shaped clamping blocks is respectively rotatably connected to one end of the first connecting rod and the second connecting rod, the outer wall of the mounting bracket is rotatably connected to three first pneumatic cylinders, and the output ends of the three are respectively rotatably connected to the middle parts of the three first connecting rods, the other side of the top surface of the base is fixedly connected to two second pneumatic cylinders, and the output ends of the two are fixedly connected to the fixing bracket, and the top surface of the fixing bracket is rotatably connected to multiple concave wheels.

[0006] Preferably, any of the above schemes is that the base is fixedly connected to one side away from the top surface of the mounting frame with four limiting square columns, and limiting square tubes that slide with the limiting square columns are provided at the four corners of the bottom surface of the fixing frame. A motor is fixedly connected to a corner of the fixing frame close to the mounting frame, and its output end is fixedly connected to one of the concave wheels. This scheme facilitates the operation of the motor to drive a concave wheel to rotate, which is used to drive the pipeline in the direction of the three arc-shaped clamping blocks, and the limiting square tube is slidably connected to the limiting square column to bear the horizontal force acting on the fixing frame, thereby preventing the two second pneumatic cylinders from being damaged by the force.

[0007] Preferably, any of the above schemes is that the bottom end of the mounting bracket is fixedly connected to one side of the top surface of the base by bolts, and a gap is left between the mounting bracket and one end of the fixing bracket. By using this scheme, a safe distance is left between the mounting bracket and the end of the fixing bracket to avoid movement interference between the two. At the same time, the mounting bracket provides an installation position for the three first pneumatic cylinders and the fixing ring, so that the three first pneumatic cylinders can be extended to synchronously push the three arc-shaped clamping blocks to move relative to each other to clamp the pipeline.

[0008] Preferably, any of the above schemes is that the fixing ring is fixedly connected to one side of the mounting frame by a bolt, and one side of the fixing ring is rotatably connected to one end of the first connecting rod and the second connecting rod respectively by a pin. By using this scheme, it is convenient to fix the fixing ring to the mounting frame, stabilize the installation position of the fixing ring, and enable relative rotation between the three first connecting rods and the second connecting rod and the fixing ring.

[0009] Preferably, any of the above schemes is that the adjacent first connecting rods and second connecting rods are placed in parallel and have the same length. The ends of the three first connecting rods and second connecting rods away from the fixed ring are rotatably connected to one side of the three mounting seats through pins. This scheme facilitates the synchronous extension of the three first pneumatic cylinders, and facilitates the synchronous promotion of the first connecting rod and the second connecting rod to move synchronously, so that the three arc-shaped clamping blocks remain relatively parallel during the movement.

[0010] Preferably, any of the above schemes is that the middle part of one side of the three mounting seats is threadedly connected with a locking bolt. This scheme facilitates fixing the end of the arc-shaped clamping block by rotating the three locking bolts. In the later stage, by loosening the three locking bolts, the three arc-shaped clamping blocks can be disassembled and replaced with arc-shaped clamping blocks with different inner diameters, thereby clamping pipes of different sizes and improving overall practicality.

[0011] The utility model has the following advantages:

[0012] 1. The processing clamping device is provided with a mounting frame and a fixing ring. One end of the three first connecting rods and the second connecting rod is provided with an arc-shaped clamping block. The three first pneumatic cylinders are synchronously extended to synchronously push the three first connecting rods and the three second connecting rods to rotate, and push the three arc-shaped clamping blocks to synchronously tighten the pipeline. At the same time, the three arc-shaped clamping blocks are distributed circumferentially to avoid clamping the pipeline, ensuring subsequent cutting processing and installation. The overall structure is simple and easy to promote and use.

[0013] 2. The processing clamping device is provided with a fixed frame and two second pneumatic cylinders. At the same time, the top surface of the fixed frame is rotatably connected to multiple concave wheels, which makes it easy to place the pipe on the top surface of the multiple concave wheels, stably supporting the suspended position of the long pipe, avoiding the pipe from bending under force, and thus facilitating the subsequent cutting process.

[0014] 3. The processing clamping device is provided with four limiting square columns and four limiting square tubes, which are connected to each other in a sliding manner. At the same time, the output ends of the two second pneumatic cylinders are fixedly connected to the bottom surface of the fixed frame. Through the extension and contraction actions of the two second pneumatic cylinders, the fixed frame and multiple concave wheels are pushed to move vertically, which is convenient for supporting pipes with different outer diameters. The limiting square columns and the limiting square tubes are connected to each other in a sliding manner to facilitate bearing the horizontal force exerted on the fixed frame and protect the two second pneumatic cylinders.

[0022] Four limiting square columns 3 are fixedly connected to the side of the base 1 away from the top surface of the mounting frame 7. Limiting square tubes 4 that slide with the limiting square columns 3 are provided at the four corners of the bottom surface of the fixing frame 5. A motor 13 is fixedly connected to the fixing frame 5 at a corner close to the mounting frame 7, and its output end is fixedly connected to a concave wheel 6.

As an optional technical solution of the present invention, this makes it easy to leave a safe distance between the mounting bracket 7 and the end of the fixing bracket 5 to avoid movement interference between the two. At the same time, the mounting bracket 7 provides an installation position for the three first pneumatic cylinders 8 and the fixing ring 12, so that the three first pneumatic cylinders 8 can extend and synchronously push the three arc-shaped clamping blocks 10 to move with each other to clamp the pipeline.

[0024] The fixing ring 12 is fixedly connected to one side of the mounting frame 7 by bolts, and one side of the fixing ring 12 is rotatably connected to one end of the first connecting rod 9 and the second connecting rod 14 respectively by pins.
