Description

Technical Field

[0001] The utility model relates to the field of cutting automation, in particular to a high-calibration tool for a plasma rotary gun. Background Art

[0002] Traditional plasma rotary cutting machines use manual positioning to calibrate the gun height. Most of them use manual positioning followed by positioning pins for positioning. When the cutting gun needs to be repaired, replaced, or seriously collided, a second manual positioning and calibration is required. The calibration steps are cumbersome and the accuracy is not high.

[0003] The current calibration method is completed by the manufacturer during production and equipped with a positioning pin positioning method; its disadvantages: it is inevitable that the cutting gun will be hit during the production process. When the cutting gun is damaged, shifted, or replaced with a different model of cutting gun, manual cooperation with the debugging personnel is required for secondary positioning. The positioning steps are cumbersome and the production personnel cannot complete it independently, which affects production efficiency. Utility Model Content

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0019] like Figure 1-2 As shown, a plasma rotary gun high calibration tool, a plasma rotary gun 1 is installed on a cutting gun holder 4 thereon, and is used to calibrate the plasma rotary gun 1 with the cutting gun holder 4, comprising: an upper plate 2, a lower plate 6, a support column 3, a side plate 5, a micrometer 7, and a positioning block 8. The two side plates 5 are connected by the upper plate 2 and the lower plate 6. The support column 3 is arranged at the lower end of the upper plate 2 for limiting the cutting gun holder 4. The micrometer 7 is used to detect the distance between the lower end of the plasma rotary gun 1 and the lower plate 6. The positioning block 8 is arranged between the plasma rotary gun 1 and the lower plate 6 for supporting the plasma rotary gun 1.

[0020] Furthermore, in this example, the upper plate 2 and the lower plate 6 are arranged in parallel, and form a square frame with the two side plates 5 .

[0021] Furthermore, in this example, an arc-shaped notch is provided on the side of the upper plate 2 for accommodating the plasma rotary gun 1 .

[0022] Furthermore, in this example, a through hole is provided on the lower plate 6 , and the through hole is arranged directly below the plasma rotary gun 1 to be calibrated, and is used for installing a micrometer 7 .

[0023] Furthermore, in this example, the micrometer 7 is a miniature micrometer 7, which improves the measurement accuracy and facilitates more convenient selection or adjustment of the positioning block 8.

[0024] Furthermore, in this example, the positioning block 8 is a plurality of positioning blocks 8 of different heights, and positioning blocks 8 of different heights can be selected according to the measurement of the micrometer 7; or the positioning block 8 is a positioning block 8 with adjustable height, and the height of the positioning block 8 can be adjusted according to the measurement of the micrometer 7.

[0025] Furthermore, in this example, the cutting gun holder 4 is a cutting gun holder 4 on the cutting machine. The relative position of the cutting gun holder 4 with respect to the cutting machine is fixed when the cutting gun is repaired, replaced, or bumped, and is therefore calibrated as a reference.

[0026] During calibration, the plasma rotary gun 1 is installed on the cutting gun holder 4 of the cutting machine and calibrated by means of a calibration tool, that is, the calibration tool is placed on the cutting gun holder 4 so that the lower end of the support column 3 is mounted on the upper end surface of the cutting gun holder 4, and the height between the plasma rotary gun 1 and the upper end of the lower plate 6 is calibrated with a micrometer 7, and the height of the positioning block 8 is adjusted or selected according to the reading. After the micrometer 7 is removed, the positioning block 8 is placed above the lower plate 6 so that it is located between the plasma rotary gun 1 and the lower plate 6, and the plasma rotary gun 1 is pressed against the upper surface of the positioning block 8, the calibration tool is removed, and the positioning block 8 is selected as a template. When the plasma rotary gun 1 needs to be adjusted, the positioning block 8 is used.

[0027] When the plasma rotary gun 1 needs to be adjusted, such as when the cutting gun is damaged, displaced, or replaced with a different model of cutting gun, it is only necessary to install the calibrated calibration tool on the cutting gun holder 4, select the positioning block 8 calibrated as a template and place it on the lower plate 6, and directly adjust the position of the plasma rotary gun 1 in the cutting gun holder 4 so that the lower end of the plasma rotary gun 1 is against the upper surface of the calibrated positioning block 8, and the upper end surface of the cutting gun holder 4 is against the lower end of the support column 3. After the adjustment is completed, lock the plasma rotary gun 1, remove the positioning block 8, and then remove the frame.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
