Problems solved by technology

The consistency of the chuck clamping is poor. After the clamping is loosened, there will be a gap between a certain jaw of the chuck and the pipe
It is inconvenient to set the clamping force. Different clamping forces should be set according to different materials, which is not automatic enough.
There are also problems such as large inertia of the chuck, slow clamping speed, and poor coaxial precision.

Embodiment Construction

[0030] The present invention will be further described in conjunction with the accompanying drawings.

[0031] see figure 1 , the present invention designs a clamping chuck correction method that can correct and compensate for the deviation of the clamping center of the pipe, and the correction is performed according to the following steps:

[0032] Step 1: Put the pipe in place, and the jaws holding the chuck return to the original point;

[0033] Step 2: Measure the deviation Δx and Δz between the pipe clamping center and the rotation center through the numerical control system;

[0034] Step 3: correcting the deviation Δx and Δz measured in step 2;

[0035] Step 4: Set the small torque upper limit;

[0036] Step 5: Set the acceleration and deceleration parameters;

[0037] Step 6: The jaws holding the chuck move synchronously and relative to each other;

[0038] Step 7: The controller continuously reads the claw position, and judges whether the claw position remains un...

Abstract

The invention relates to the technical field of a clamping chuck in a three-dimensional pipe laser cutting system, in particular to a clamping chuck capable of correcting and compensating deviation ofthe clamping center of a pipe and a correction method. The clamping chuck and the correction method are characterized in that clamping jaws move to designated positions and then are locked, after themaximum moment is set, in the movement process, the passive force provided by the clamping jaws of the clamping chuck only needs to be large enough to maintain the situation that the pipe does not relatively move and needs to avoid the situation that the pipe is damaged due to overlarge clamping force. Compared with a traditional clamping chuck which only has two states, namely, on and off, and has too large clamping force hard to adjust during clamping, the clamping chuck has the advantages that great improvement is achieved, meanwhile, it is ensured that the mass center of the pipe coincidewith the rotating center of the clamping chuck, so that the whole cutting system is more stable, and the clamping force is controllable.

Description

technical field [0001] The invention relates to the technical field of clamping chucks in a three-dimensional pipe laser cutting system, in particular to a clamping chuck and a correction method for correcting and compensating the center deviation of pipe material clamping. Background technique [0002] In the pipe cutting system, the chuck is an important part to ensure that the position of the pipe is stable during the cutting process, ensuring that the entire cutting process is carried out at high speed and high efficiency, thereby improving production efficiency and product quality. Chucks currently on the market still have many problems. The consistency of the chuck clamping is poor. After the clamping is loosened, there will be a gap between a certain jaw of the chuck and the pipe. It is inconvenient to set the clamping force. Different clamping forces should be set according to different materials, which is not automatic enough. There are also problems such as large...
