Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting and mainly relates to a plate positioning auxiliary device. Background Art

[0002] Most of the cabinets of climate environment testing equipment are made of sheet metal. A large number of sheet metal cutting tasks will be required every day during production. Conventional sheet metal laser cutting is done by manually moving the sheets to align the sheets, and then confirming by moving the frame. Repeated operations are performed to verify whether the sheets are centered. After correction, personnel will perform positioning and cutting.

[0003] Because the plate placement does not overlap with the cutting axis or the plate placement is not vertical, there will be plate residue and limited cutting range after cutting. Since the laser cutting equipment has adjusted the travel route in advance, when the plate is offset, the residue line will exceed the travel range of the laser cutting equipment, resulting in size differences between the front and rear ends of the residue, causing plate waste. At this time, the uncut residue needs to be manually broken by personnel climbing onto the platform, which is a huge workload. Utility Model Content

[0007] Beneficial effects: The plate can be positioned by the positioning block, which improves material utilization and part cutting integrity. The position of the cross laser is adjusted by the adjustment mechanism until the laser point of the cross line emitted by the cross laser is used to overlap with the projection of the intersection between the two corresponding mutually perpendicular side surfaces of the plate in the vertical direction, and the two side lines of a specific right angle of the cross line emitted by the cross laser are used to overlap with the projection of the two corresponding mutually perpendicular side surfaces of the plate in the vertical direction. At this time, laser cutting can be performed by simply aligning the laser cutting stroke origin with the laser point of the cross laser, ensuring the accuracy of the laser cutting plate path, and thus ensuring the accuracy of plate cutting, and no longer needing to go through the frame step, thereby improving work efficiency.

[0014] Furthermore, the mounting frame is a U-shaped structure, including a top plate and a bottom plate arranged parallel to each other and a connecting plate vertically connected between the top plate and the bottom plate. The mounting part is fixed on the side of the bottom plate facing the top plate, and a through hole is provided on the top plate that is coaxial with the positioning hole for the cross laser to pass through.

[0015] Beneficial effects: the mounting frame is a U-shaped structure, which saves materials; a through hole coaxial with the positioning hole is provided on the top plate for the cross laser to pass through, which prevents the tail of the cross laser from swinging when the cross laser is slid, thereby ensuring the stability of the cross laser.

[0029] Embodiment 1 of a plate positioning auxiliary device provided by the present utility model:

[0030] like Figure 1 As shown, a plate positioning auxiliary device includes a cross laser 7, an adjustment mechanism, and a positioning block. In this embodiment, for ease of description, the length direction of the fixing base 1 is defined as the front-to-back direction, the width direction of the fixing base 1 is defined as the left-to-right direction, and the height direction of the fixing base 1 is defined as the up-down direction.

[0031] The cross laser 7 is mounted on a support frame. The positioning block is long and consists of two pieces: one welded to the X-axis of the laser cutting platform, and the other welded to the Y-axis. When placing a sheet, ensure that one side of the sheet's origin aligns with the corresponding positioning block to prevent it from being placed askew. The adjustment mechanism includes a fixed seat 1, a movable seat, and a support frame.

[0032] The fixing seat 1 is provided with a fastening hole, and the fixing seat 1 is fixed above the laser cutter by fastening bolts. The front and rear directions of the fixing seat 1 are consistent with the X-axis direction of the laser cutting platform, and the left and right directions of the fixing seat 1 are consistent with the Y-axis direction of the laser cutting platform.

[0033] The movable seat includes an integrally formed movable plate 4 and a seat body 6 perpendicular to the movable plate 4. Two sliders 3 extending in the front-to-back direction are fixed to the movable plate 4. Two slide rails 2 arranged in parallel and corresponding to the sliders 3 are fixed to the fixed seat 1. The sliders 3 are slidably assembled with the slide rails 2, and the movable seat can slide back and forth along the slide rails 2. The slide rails 2 are also provided with anti-slip grooves 13 extending in the front-to-back direction at the upper and lower ends. The sliders 3 are provided with anti-slip blocks corresponding to the anti-slip grooves 13 on the top. The anti-slip blocks are stuck in the anti-slip grooves 13 and slide to prevent the movable seat from falling off the fixed seat 1 when sliding.

[0034] The support frame is a split structure, comprising a movable frame 5 and a mounting frame, detachably connected by fastening bolts. The base 6 is provided with a left-right extending receiving slot for accommodating the movable frame 5. The front and rear walls of the receiving slot are respectively provided with left-right extending slide grooves 12. The movable frame 5 is provided with a slide bar that slidably engages with the slide grooves 12. The slide bar and the slide groove 12 slidably engage, allowing the movable frame 5 to slide left and right along the slide bar. The movable frame 5 is positioned within the receiving slot, ensuring stability during sliding. The mounting frame is a U-shaped structure, including a top plate 8 and a bottom plate 9 arranged in parallel up and down, and a connecting plate 10 vertically connected between the top plate 8 and the bottom plate 9. A sleeve 11 is vertically welded on the bottom plate 9. The sleeve 11 is located on the side of the bottom plate 9 facing the top plate 8, and the bottom plate 9 is provided with a circular hole corresponding to the sleeve 11. The head of the above-mentioned cross laser 7 is installed in the sleeve 11, and the cross rays emitted from the head of the cross laser 7 are emitted from the circular hole. Two locking bolts 15 evenly distributed on the circumference are threadedly connected to the sleeve 11. The locking bolts 15 are perpendicular to the axis of the sleeve 11, and the cross laser 7 is locked in the sleeve 11 by the two locking bolts 15. A through hole coaxial with the sleeve 11 is provided on the top plate 8 for the cross laser 7 to pass through. The through hole has the same diameter as the cross laser 7. The head of the cross laser 7 is clamped in the sleeve 11 by the locking bolt 15, and the tail passes through the through hole, ensuring that the cross laser 7 is vertically fixed. When installing the cross laser 7, the two mutually perpendicular rays emitted need to extend in the front-to-back and left-to-right directions respectively.

[0035] The seat body 6 and the movable frame body 5 are both provided with a weight-reducing long hole 14 extending in the left-right direction. The design of the weight-reducing long hole 14 makes the plate positioning auxiliary device lighter, facilitates transportation and installation, and saves materials.

[0036] The working process of this utility model is as follows:

[0037] First, install the plate positioning auxiliary device to the corresponding position above the laser cutter, ensuring that the front-to-back direction of the fixing base 1 is consistent with the X-axis direction of the laser cutting platform, and the left-to-right direction of the fixing base 1 is consistent with the Y-axis direction of the laser cutting platform. At the same time, clamp the cross laser 7 in the sleeve 11 through the locking bolt 15 to ensure that the cross laser 7 is fixed vertically. When installing the cross laser 7, it is necessary to extend the two mutually perpendicular rays emitted in the front-to-back and left-to-right directions respectively. Then place the plate to be cut on the laser cutting platform so that one side of the origin of the plate to be cut is in contact with the corresponding slider 3 to prevent the plate to be cut from tilting. Then manually move the cross laser 7 so that the projection of the laser point of the cross laser 7 on the laser cutting platform overlaps with the origin of the plate to be cut, and the projection of the two sides of the specific 90-degree angle of the cross laser 7 on the laser cutting platform overlaps with the specific two sides of the origin of the plate to be cut. Then position the origin of the laser cutting stroke to the position of the laser point of the cross laser 7 and start cutting.

[0038] At this time, laser cutting can be performed by simply aligning the laser cutting stroke origin with the laser point of the cross laser 7, ensuring the accuracy of the laser cutting plate path, and then ensuring the accuracy of the plate cutting, and no longer needing to go through the frame step, thereby improving work efficiency.
