Positioning device for steel plate numerical control cutting and positioning method

Abstract

The invention discloses a positioning device for steel plate numerical control cutting. The positioning device comprises a first positioning mechanism and a second positioning mechanism which are mounted on an operation platform and used for positioning a to-be-cut steel plate, and the first positioning mechanism and the second positioning mechanism are located on the same side of the to-be-cut steel plate; and the first positioning mechanism comprises a first base plate, a first slippage base installed on the first base plate and a first positioning plate installed on the first slippage baseand used for positioning the to-be-cut steel plate. The invention discloses a positioning method. The positioning method comprises the steps that firstly, the first base plate and the second base plate are adjusted; secondly, the first slippage base and a second slippage base are adjusted; thirdly, the to-be-cut steel plate is positioned; and fourthly, numerical control cutting on the to-be-cut steel plate is carried out. By means of the positioning device, repeated measurement and repeated adjustment by operators are not needed, and adverse effects of cuttings or splashes on the positioning accuracy of the first positioning plate or the second positioning plate can be prevented. By means of the positioning method, the positioning working efficiency and the positioning accuracy can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of steel plate cutting, and in particular relates to a positioning device and a positioning method for numerically controlled cutting of steel plates. Background technique [0002] The raw steel plates for the existing pressure steel pipes are all made of cut-to-length steel plates. The cut-to-length steel plates refer to the width greater than or equal to 150mm, and the thickness is usually greater than 4mm. Generally, they are delivered in straight strips, not in coils. For water chestnut steel, in the process of cutting steel plates to length, in order to ensure the roundness of assembled steel pipes after rolling, the cutting allowance is required to be small, and the cutting error is not greater than 2mm, which requires high precision. The positioning method is as follows: before each steel plate cutting, the operator uses a tape measure to measure the distance between the edge of the steel plate to be ...

[0002] The raw steel plates for the existing pressure steel pipes are all made of cut-to-length steel plates. The cut-to-length steel plates refer to the width greater than or equal to 150mm, and the thickness is usually greater than 4mm. Generally, they are delivered in straight strips, not in coils. For water chestnut steel, in the process of cutting steel plates to length, in order to ensure the roundness of assembled steel pipes after rolling, the cutting allowance is required to be small, and the cutting error is not greater than 2mm, which requires high precision. The positioning method is as follows: before each steel plate cutting, the operator uses a tape measure to measure the distance between the edge of the steel plate to be cut and the track of the cutting machine, and multiple adjustments are required. The positioning construction efficiency is low and the positioning accuracy is poor.
