Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, and particularly relates to a drag chain structure of a laser cutting machine. Background Art

[0002] On a laser cutting machine, a drag chain mechanism is a device for protecting, managing, and guiding moving cables and hoses. The drag chain mechanism is usually installed along the X-axis and Y-axis moving axes of the laser cutting machine. The existing drag chain mechanism generally includes a drag chain, a drag chain guiding groove, and other connecting parts. The drag chain is slidably connected in the drag chain guiding groove, and the drag chain guiding groove is connected to the fuselage of the laser cutting machine through a drag chain groove bracket, and the drag chain groove bracket plays a role in supporting and fixing the drag chain guiding groove.

[0003] However, during the long-term processing of metal sheets by the existing laser cutting machine, metal chips, dust, and smoke will be generated. In addition, a large surrounding component is installed on the outside of the laser cutting machine, so that more metal chips or impurities will accumulate in the drag chain guiding groove, resulting in continuous friction and heating between the metal chips or impurities and the drag chain and the drag chain guiding groove, and wear of the drag chain and the drag chain guiding groove will occur, especially obvious under high-speed and high-load operations;

[0004] Moreover, when the laser cutting machine is under low load, it is more appropriate for the drag chain groove bracket to support at the root or middle of the drag chain guiding groove. Under high load, it is more appropriate to support at the suspended part on the outside of the drag chain guiding groove. Because the connection position between the existing drag chain groove bracket and the drag chain guiding groove is usually fixed, it is not suitable for stably supporting the drag chain guiding groove of the laser cutting machine under low load or high load. Content of the Utility Model

[0005] In order to solve the technical problems existing in the above background art, the utility model provides a drag chain structure of a laser cutting machine.

[0006] The technical solution of the utility model is as follows:

[0007] A drag chain structure of a laser cutting machine is arranged on one side of the laser cutting machine. The laser cutting machine includes a fuselage, and a longitudinal sliding seat is slidably connected along the length direction of the fuselage. The drag chain structure is arranged on the longitudinal sliding seat. The drag chain structure includes a drag chain guide rail and a drag chain, both of which are arranged along the length direction of the fuselage. The drag chain guide rail is connected to the longitudinal sliding seat through a drag chain bracket;

[0008] The drag chain guide rail has an inner bottom surface, and a plurality of blanking long grooves are arranged along the length direction of the inner bottom surface. The length direction of the blanking long groove is not parallel to the length direction of the inner bottom surface, and one end of the blanking long groove extends to one side of the inner bottom surface along the width direction;

[0009] The drag chain support includes a vertical plate and a horizontal plate connected end to end. The horizontal plate is located below the vertical plate and can be telescoped along the length direction of the drag chain guide rail. The upper end of the vertical plate is connected to the lower end face of the drag chain guide rail, and one end of the horizontal plate is connected to the longitudinal sliding seat.

[0010] An adjusting long groove is provided in the middle of the bottom surface along its length direction. A plurality of connecting pieces are provided at the upper end of the vertical plate, and the connecting pieces pass through the blanking long groove and the adjusting long groove respectively to be connected to the drag chain guide rail.

[0011] When the drag chain moves on the drag chain guide rail, it will drive metal chips or impurities to move on the inner bottom surface of the drag chain guide rail and fall from a plurality of blanking long grooves, reducing the wear and heat generation caused by metal chips or impurities to the drag chain and the drag chain guide rail, prolonging the service life of the drag chain and the drag chain guide rail, and setting the position of the vertical plate on the drag chain guide rail to be adjustable, enabling the position of the vertical plate on the drag chain guide rail to be quickly adjusted before the high-speed and high-load operation of the cutting machine, without the need to support the suspended part of the drag chain guide rail by adding a support frame and drilling holes in the drag chain guide rail.

[0012] To prevent the upper end of the connecting piece from being higher than the inner bottom surface and affecting the movement of the drag chain, the height of the horizontal plane where the upper end surface of the connecting piece is located is set not to be higher than the height of the horizontal plane where the inner bottom surface is located.

[0013] Regarding the specific structure of the blanking long groove, first chamfers are provided at the joints of the blanking long groove and the inner bottom surface. The maximum outer diameter of the upper end of the connecting piece is located between the width of the upper port and the width of the lower port of the blanking long groove. The first chamfer also facilitates the rapid movement of metal chips or impurities to the blanking long groove through the inclined surface formed by the chamfer.

[0014] Regarding the specific structure of the adjusting long groove, second chamfers are provided at the joints of the adjusting long groove and the inner bottom surface. The maximum outer diameter of the upper end of the connecting piece is located between the width of the upper port and the width of the lower port of the adjusting long groove.

[0015] The arrangement position of the above-mentioned blanking long grooves is that a plurality of blanking long grooves are symmetrically arranged on both sides of the adjusting long groove, and the blanking long grooves are not communicated with the adjusting long groove.

[0016] The drag chain moves along the length direction of the drag chain guide rail. To facilitate the rapid movement of metal chips or impurities to the blanking long groove, the blanking long groove is vertically arranged perpendicular to the adjusting long groove to form a cross-shaped positioning. Compared with arranging the connecting piece along the length direction of the blanking long groove or the adjusting long groove, the fixing effect can be improved.

[0017] Regarding the arrangement position of a plurality of connecting pieces, a plurality of connecting pieces are arranged in a cross shape on the upper end surface of the vertical plate, so that a plurality of connecting pieces can pass through the blanking long groove and the adjusting long groove at the same time.

[0018] The specific structure of the above drag chain guide rail is that the drag chain guide rail includes a bottom plate and side plates located on both sides along the length direction. One end of the blanking long groove is arranged close to the side plate, and an arc surface is provided at the joint with the side plate, which is beneficial for the falling of metal chips or impurities.

[0019] To facilitate the simultaneous installation of the above-mentioned multiple connecting pieces in the blanking long groove and the adjusting long groove, the vertical distance between two adjacent blanking long grooves along the length direction of the drag chain guide rail is less than the length of the adjusting long groove, and it is convenient to adjust the vertical plate to any position below the drag chain guide rail.

[0020] The beneficial effect of the present utility model is that, to facilitate the movement of the drag chain on the drag chain guide rail, the width of the drag chain guide rail is slightly larger than the width of the drag chain, so that there is a gap between the two sides of the drag chain and the drag chain guide rail. Metal chips or impurities will accumulate in the gap, and more metal chips or impurities will accumulate on both sides of the inner bottom surface relative to the middle part. For this reason, multiple blanking long grooves are symmetrically arranged on both sides of the adjusting long groove, and one end of the blanking long groove is arranged close to the side plate of the drag chain guide rail, which can drive the metal chips or impurities accumulated on the inner bottom surface to the blanking long groove by the drag chain under the condition of the instability of the drag chain moving in the width direction of the drag chain guide rail;

[0021] Under low-load and high-load conditions of the laser cutting machine, the influence on the suspended part of the exposed drag chain bracket of the drag chain guide rail is different. Under low-load conditions, it is more appropriate for the drag chain bracket to support at the root or middle of the drag chain guide rail; under high-load conditions, this fixed position will cause severe shaking of the suspended part. Therefore, by quickly adjusting the position of the vertical plate below the drag chain guide rail, setting it close to the outer end along the length direction of the drag chain guide rail, and at the same time, the transverse plate adaptively extends, so that under high-load conditions of the laser cutting machine, the drag chain guide rail can still play a stable supporting effect on the drag chain guide rail.

[0032] To facilitate the simultaneous installation of the above-mentioned plurality of connecting pieces 7 in the blanking long groove 311 and the adjusting long groove 312, the vertical distance between two adjacent blanking long grooves 311 along the length direction of the drag chain guide rail 3 is less than the length of the adjusting long groove 312, and it is convenient to adjust any position of the vertical plate 5 below the drag chain guide rail 3.
