Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, in particular to a rapid positioning jig for laser cutting. Background Art

[0002] During the laser cutting production operation, the conventional positioning method is to manually place the material to be cut on the approximate position of the vacuum adsorption table, and select the positioning point on the computer to position the material to be cut.

[0003] This existing method has two disadvantages. The first is efficiency. Laser processing time is cost. Long operation time directly affects efficiency and production capacity. Second, for some thinner slices to be cut, when they are manually placed on the vacuum table, the sheet is soft and difficult to place in the desired position, resulting in a large amount of laser equipment time being occupied, which greatly affects the production capacity of the laser equipment. To address this pain point, this patent provides a fast positioning fixture that can be quickly replaced, reduces operation time, and improves equipment efficiency. Utility Model Content

[0008] Preferably, a masking paper is placed on the top of the vacuum adsorption table, and the masking paper covers the outer area of ​​the tray. When the vacuum is turned on by the set vacuum adsorption table, the vacuum will adsorb the pieces to be cut.

[0009] Preferably, the limiting member is in an "L" shape, and two sides of the tray are fitted on two sides of the limiting member, so that the tray is limited by the setting of the limiting member.

[0025] like Figure 1-4 As shown, the utility model provides a rapid positioning fixture for laser cutting, including a vacuum adsorption table 1, on which a piece to be cut 4 is arranged, and a tray 3 for carrying the piece to be cut 4 is arranged on the top of the vacuum adsorption table 1, and the tray 3 includes: a pad paper 302 and a surrounding frame 301, and the tray 3 is placed on the top of the vacuum adsorption table 1, and the pad paper 302 is bonded to the bottom of the surrounding frame 301 by glue, and the surrounding frame 301 is in a "U" shape, and the inner side of the surrounding frame 301 is set to limit the piece to be cut 4, and the thickness of the pad paper 302 is 0.15mm. The purpose of setting the pad paper 302 is to have suitable air permeability, so that the subsequent vacuum adsorption table 1 can absorb the piece to be cut 4 through the pad paper 302, and the inner side of the surrounding frame 301 is inclined, and the inclined surface is set on the inner side of the surrounding frame 301 to avoid affecting the subsequent laser processing optical path, and the top of the vacuum adsorption table 1 is also bonded with a limiting member 2 by glue, and the limiting member The piece 2 is in an "L" shape, and the two sides of the tray 3 are fitted on the two sides of the limit piece 2. The limit piece 2 is set to limit the tray 3. The upper left corner of the piece 4 to be cut is close to the upper left corner of the inner frame of the tray 3. The limit piece 2 is made of CNC. A masking paper is placed on the top of the vacuum adsorption table 1, and the masking paper covers the outer area of ​​the tray 3. When the vacuum is turned on by the vacuum adsorption table 1, the vacuum will adsorb the piece 4 to be cut. This fixture solves the problem of low efficiency in selecting positioning points in laser cutting operations. The fixture is simple to make and low in cost. It can be adapted to material sheets of any size and shape. The fixture has accurate positioning, and the raw material position accuracy is within 0.5mm, which meets most laser processing requirements. The rotation method of the fixture reduces the operator's positioning operation on the equipment, and is placed outside the equipment for preparatory operation, which greatly reduces the time occupied by the equipment and improves the utilization rate of the laser equipment, thereby increasing production capacity.

[0026] The following is a detailed description of the working principle of this rapid positioning fixture for laser cutting.

[0027] like Figure 1-4As shown, first, a quick positioning fixture for laser cutting is placed in the corresponding working position, and then the various components of the device are checked to confirm whether they are working properly. After the inspection is completed, it can be used. When using it, before cutting, the piece 4 to be cut is placed in the tray 3 composed of the surrounding frame 301, and the upper left corner of the piece 4 to be cut is close to the upper left corner of the inner frame of the tray 3, and then the tray 3 is placed on the vacuum adsorption table 1, and the two sides are close to the two sides of the L-shaped limiter 2. At this time, use masking paper to cover other areas on the vacuum adsorption table 1, and then turn on the vacuum, the vacuum will adsorb the piece 4 to be cut, and set it on the computer. Set the positioning program, save the current position coordinates, and start laser cutting. At the same time, we put the second piece to be cut 4 on the upper left corner of another tray 3 for processing. After the first piece is cut, we take down the tray 3 as a whole, and put the pre-prepared tray 3 with the second piece to be cut 4 on the position of the upper limit piece 2 on the adsorption table. The computer does not need to position again, and starts laser processing directly. At the same time, take the first piece off the tray 3, put the third piece to be cut 4 on it, and wait for processing. This reciprocating process greatly reduces the time that the positioning operation takes up the laser equipment.
