Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary clamping devices, in particular to an auxiliary clamping device for pipe processing that can be flexibly adjusted. Background Technique

[0002] With the continuous upgrading and refinement of the manufacturing industry, the requirements for the precision and quality of pipe processing are getting higher and higher, and the processing technology is also constantly improving. During the processing, the clamping device for pipes is a common device, which can ensure that the pipe will not move or shake during processing, providing a basis for precise processing.

[0003] When the existing auxiliary clamping device is in use, it cannot be flexibly adjusted for pipes of different specifications, and its applicability is poor. Moreover, when rotating and processing the pipe for one week, it is necessary to manually rotate the pipe in the center, wasting manpower and having low work efficiency.

[0004] Therefore, it is urgently necessary to set up a structure that can be flexibly adjusted according to the gear of the pipe to be processed, so that it can adapt to pipes of different gears, and then add a structure that can automatically rotate the pipe in the center, so that when processing the pipe for one week, there is no need to manually flip or move the pipe, saving time and physical strength. Summary of the Utility Model

[0005] In order to overcome the problems that the auxiliary clamping device cannot be flexibly adjusted for pipes of different specifications, has poor applicability during use, and when rotating and processing the pipe for one week, it is necessary to manually rotate the pipe in the center, wasting manpower and having low work efficiency.

[0006] The technical solution of the utility model is: an auxiliary clamping device for pipe processing that can be flexibly adjusted, including a device fixed bottom plate, a first cylinder, a frame support hanging plate, a pipe tightening and loosening adjustment clamping assembly, a pipe upper end fixing assembly, a pipe auxiliary support plate, and a transmission belt; the upper end of the device fixed bottom plate is provided with a first cylinder; the output end of the first cylinder is fixedly connected with a frame support hanging plate; the upper end of the frame support hanging plate is provided with a pipe tightening and loosening adjustment clamping assembly; above the pipe tightening and loosening adjustment clamping assembly is provided with a pipe upper end fixing assembly; the side end of the frame support hanging plate is fixedly connected with a pipe auxiliary support plate; the transmission belt is arranged inside the pipe auxiliary support plate.

[0007] Preferably, by utilizing the flexible adjustment function of the pipe tightening and loosening adjustment clamping assembly, pipes of various different diameters can be clamped. Pipes ranging from thin to thick can be firmly fixed, eliminating the need to replace different pipe clamping devices for different pipes. At the same time, stable clamping can ensure subsequent processing accuracy. Additionally, when the clamping force is relaxed, the pulley block and the pulley placement bottom plate, in conjunction with the transmission belt, can enable the pipe to rotate around its center, facilitating processing around the entire circumference of the pipe. The pipe upper end fixing assembly can perform wrap-around clamping on the side and top of the pipe, making it more stable during processing and enhancing the safety of the operator.

[0008] Preferably, the pipe tightening and loosening adjustment clamping assembly includes a driving motor, a transmission rotating rod, a driving main gear, a driven gear strip plate, an arc-shaped pipe fixing block, a first pressure-bearing spring, a movable support rod, a pulley block, an anti-slip rubber plate, a second pressure-bearing spring, and a pulley placement bottom plate; a driving motor is installed at the lower end of the framework support hanging plate; the output shaft of the driving motor passes through the framework support hanging plate and is fixedly connected to the transmission rotating rod, and the driving motor drives the transmission rotating rod to rotate.

[0009] Preferably, the outer end of the transmission rotating rod is fixedly connected to the driving main gear; a driven gear strip plate is slidably connected inside the framework support hanging plate; and the driven gear strip plate meshes with the driving main gear; the upper end of the driven gear strip plate is fixedly connected to the arc-shaped pipe fixing block; a movable support rod is slidably connected through the arc-shaped pipe fixing block in a penetrating manner, and the lower end of the movable support rod is fixedly connected to the first pressure-bearing spring. The transmission rotating rod rotates the driving main gear, which drives the driven gear strip plate under the transmission of mechanical force; this causes the arc-shaped pipe fixing block above it to approach the pipe to be processed until it is completely in contact, achieving the clamping and fixing effect at the bottom.

[0010] Preferably, the upper end of the movable support rod is hinged to the pulley block; an anti-slip rubber plate is installed at the upper end of the framework support hanging plate; a second pressure-bearing spring is arranged inside the anti-slip rubber plate; the upper end of the second pressure-bearing spring is fixedly connected to the pulley placement bottom plate. When the clamping force is not sufficient, the movable support rod, under the elastic force of the first pressure-bearing spring at its lower end, causes the pulley block to contact the pipe to be processed. When used in conjunction with the pulley placement bottom plate, the pipe is in a suspended state, and in conjunction with the transmission belt, the pipe can rotate around its center.

[0011] Preferably, the pipe upper end fixing assembly includes a connecting frame plate, a second cylinder, an installation connecting plate, an auxiliary guiding rod, a side-end clamping push plate, a hydraulic telescopic rod, and an upper-end anti-slip pressing plate; the upper end of the framework support hanging plate is fixedly connected to the connecting frame plate; a second cylinder is installed at the upper end of the connecting frame plate; the output end of the second cylinder passes through the connecting frame plate and is fixedly connected to the installation connecting plate, and the second cylinder drives the installation connecting plate to press downward, causing the upper-end anti-slip pressing plate to contact the pipe to be processed.

[0014] Advantages of the present utility model:

[0015] 1. During the use of the auxiliary clamping device, it cannot be flexibly adjusted for pipes of different specifications, and its applicability is poor. Also, when rotating and processing the entire circumference of the pipe, manual rotation of the pipe is required, which wastes manpower and has low work efficiency. Therefore, by utilizing the flexible adjustment function of the pipe tightening and loosening adjustment clamping assembly, pipes of various different diameters can be clamped. From small pipes to large pipes, they can be firmly fixed without the need to replace different pipe clamping devices for different pipes. At the same time, stable clamping can ensure subsequent processing accuracy. Additionally, when the clamping force is relaxed, the pulley block and the pulley placement bottom plate, in cooperation with the transmission belt, can make the pipe rotate centrally, facilitating the processing of the entire circumference of the pipe. And the pipe upper-end fixing assembly can perform wrap-around clamping on the side and top of the pipe, making it more stable during processing and also improving the safety of the operator.

[0016] 2. The driving motor drives the transmission rotating rod to rotate. The transmission rotating rod makes the driving main gear rotate, and under the transmission of mechanical force, it drives the driven gear strip; this causes the arc-shaped pipe fixing block above it to approach the pipe to be processed until it is completely in contact, playing a role in clamping and fixing at the bottom. When the clamping force is not tight enough, the movable support rod, under the elastic force of the first pressure spring at its lower end, makes the pulley block contact the pipe to be processed. Then, in cooperation with the pulley placement bottom plate, the pipe is in a suspended state, and in cooperation with the transmission belt, the pipe can rotate centrally.

[0017] 3. The second cylinder drives the mounting connecting plate to press downward, so that the upper-end anti-slip pressing plate contacts the pipe to be processed. The hydraulic telescopic rod pushes the side-end clamping push plate to clamp and fix the side of the pipe, improving the stability of the fixation. Description of the Drawings
