Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting, in particular to a multi-section bed alignment structure. Background Art
[0002] The application of laser cutting machines has developed rapidly in the domestic market in recent years, especially in the field of sheet metal cutting and processing. It has the advantages of high cutting accuracy, fast cutting speed, adaptability to various complex graphics, automatic typesetting, smooth incision, low processing cost, etc. It has replaced punching machines, flame cutting, plasma cutting and other equipment.
[0003] With the continuous updating of laser cutting technology, there is an increasing demand for high-power laser cutting machines. Among them, the use of ground-track laser cutting machines is very extensive, which has brought great convenience to industrial production. The bed of the current ground-track laser cutting machine mainly welds pipes and plates together by welding. The longest bed of the ground-track laser cutting machine on the market is only 12 meters. Multiple beds need to be welded to form a larger-format ground-track laser cutting machine. As a result, once the welding of the large-format ground-track laser cutting machine is completed, its cutting stroke is fixed and cannot be switched again. It is also difficult to transfer and transport. In addition, the high-temperature molten iron filings generated by the cutting mechanism during the cutting process fall on the bed or the serrated support plate. This will cause the bed and the serrated support plate to deform for a long time. The serrated support plate can be replaced regularly as a consumable, but the bed as an integral component is expensive and fixed by welding and cannot be replaced regularly. Under long-term use, the bed of the large-format ground-track laser cutting machine may be deformed, affecting the laser cutting efficiency.
[0004] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable large-format ground-rail laser cutting machine that can be spliced in multiple sections or a multi-section cutting machine bed alignment and splicing structure. Utility Model Content

[0027] Embodiment 1: Figures 1 to 3The figure shown is only one of the embodiments of the present invention, a multi-section bed alignment structure, including a first bed 4, a second bed 5 and an alignment portion for connecting the first bed 4 and the second bed 5, the guide rails on the first bed 4 and the second bed 5 are provided with functional holes 41, the lower sides of the first bed 4 and the second bed 5 are provided with adjustment feet 42 and a lower probe plate 43; the alignment portion includes a tightening guide plate 1 and left and right adjustment plates 2; the tightening guide plate 1 is provided with a tightening hole 11 and a tightening column 12 for passing through the tightening hole 11 and inserted into the functional hole 41, the left and right adjustment plates 2 are provided with an adjustment hole 21 and an adjustment screw rod 22 for passing through the adjustment hole 21 and extending toward the lower probe plate 43, and the adjustment hole 21 is provided with an internal thread.
[0028] In the present invention, the first bed 4 and the second bed 5 refer to two adjacent bed frames when a multi-section spliced bed frame is connected. In fact, the multi-section bed frame includes a front bed frame, a middle bed frame and a rear bed frame. Any two adjacent bed frames are the same when connected, and can be counted as the first bed frame 4 and the second bed frame 5. Then, the alignment part is used to align the first bed frame 4 and the second bed frame 5 for easy fixed installation, and then the laser head slides on the bed frame to perform laser cutting of the plate.
[0029] First, the structures of the first bed 4 and the second bed 5 are provided on the first bed 4 and the second bed 5 with guide rails for facilitating the sliding of the laser head (crossbeam), and functional holes 41 are arranged at intervals on the guide rails. Adjustment feet 42 and a lower probe plate 43 are provided on the lower sides of the first bed 4 and the second bed 5.
[0030] Next is the structure of the alignment part, which includes a tensioning guide plate 1 and left and right adjustment plates 2;
[0031] The tightening guide plate 1 is provided with a tightening hole 11 and a tightening plug 12 for passing through the tightening hole 11 and being inserted into the functional hole 41. When the first bed 4 and the second bed 5 are displaced to adjacent positions, the tightening plug 12 passes through the tightening hole 11 and is inserted into the functional hole 41. At least two functional holes 41 on the first bed 4 and the second bed 5 are inserted with the tightening plug 12, so that the approximate positions of the first bed 4 and the second bed 5 can be tightened and limited; the alignment of the first bed 4 and the second bed 5 in the extension (front and back) direction is completed;
[0032] The left and right adjustment plates 2 are provided with adjustment holes 21 and adjustment screw rods 22 for extending through the adjustment holes 21 toward the direction of the lower probe plate 43. The adjustment holes 21 are provided with internal threads. The lower probe plate 43 extends downward and is arranged parallel to the first bed 4. The adjustment screw rod 22 is extended perpendicularly to the lower probe plate 43, that is, it is arranged perpendicularly to the first bed 4. The adjustment screw rod 22 in the adjustment hole 21 is screwed to extend to the lower probe plate 43. After it is against the lower probe plate 43, the adjustment screw rod 22 is continued to be screwed, so that the lower probe plate 43 and the bed structure can be pushed to move in the left and right directions, thereby completing the left-right alignment of the first bed 4 and the second bed 5.
[0033] Furthermore, adjusting feet 42 are provided at the lower sides of the first bed frame 4 and the second bed frame 5 , and the heights of the first bed frame 4 and the second bed frame 5 can be adjusted by adjusting the adjusting feet 42 to achieve alignment of the first bed frame 4 and the second bed frame 5 in the upper and lower directions.
[0034] It should be noted that the tensioning guide plate 1 is an elastic member. To be precise, the tensioning guide plate 1 has the ability to bend elastically but not the ability to stretch in length, that is, it is an elastic member with strong tensile resistance but weak bending resistance. This ensures that as long as the first bed 4 and the second bed 5 are connected to the tensioning guide plate 1 through the tensioning plug 12, the ends of the first bed 4 and the second bed 5 can be tightly tightened, and the first bed 4 and the second bed 5 can still be tightened even if they are not aligned in the up, down, left, and right directions.
[0035] In summary, in the present invention, the steps for aligning a multi-section bed are as follows: first, the first bed 4 and the second bed 5 are moved to adjacent positions, and the first bed 4 and the second bed 5 are tightened by tightening the guide plate 1 and the tightening column 12 to complete the front-to-back alignment; then, the left-right and up-and-down positions of the first bed 4 and the second bed 5 are adjusted by adjusting the adjusting feet 42 and the left-right adjusting plates 2 to complete the left-right and up-and-down alignment. At this time, the first bed 4 and the second bed 5 are completely aligned and stable, and can be fixedly connected and installed.

On the basis of the first embodiment, in a multi-section bed alignment structure of the present invention, the alignment portion also includes a height adjustment member 3, and the height adjustment member 3 includes a fixed wedge block 31 for connecting to the bottom of the lower probe plate 43 and a wedge-shaped bevel block 32 for connecting to the fixed wedge block 31, and the number of the wedge-shaped bevel block 32 is at least one.
[0037] In this way, the bed is roughly adjusted in the up-down direction by adjusting the foot 42, and then the wedge-shaped inclined block 32 is horizontally displaced to squeeze the fixed wedge block 31 to complete the fine adjustment of the bed in the up-down direction, ensuring that the bottoms of the first bed 4 and the second bed 5 are precisely flush.
[0038] In fact, since the fixed wedge block 31 is connected to the bottom of the lower probe plate 43, when aligning the left and right and up and down positions of the first bed 4 and the second bed 5, the specific steps should be: use the adjusting foot 42 to make a rough adjustment in the up and down direction of the bed, and then use the wedge-shaped inclined block 32 to horizontally displace and squeeze the fixed wedge block 31 to complete the fine adjustment in the up and down direction of the bed. At this time, the fixed wedge block 31 and the lower probe plate 43 are fixed, that is, the height has been determined and the adjustment is completed and the height is fixed; finally, the left and right position is adjusted relative to the fixed lower probe plate 43 by the left and right adjustment plates 2.

On the basis of the first embodiment, in a multi-section bed alignment structure of the present invention, the number of the adjusting screw rod 22 and the lower probe plate 43 is two. Theoretically, the left and right sides of the bed are provided with adjusting screw rods 22. Through synchronous adjustment on both sides, the sides of the first bed 4 and the second bed 5 are precisely flush, and the left and right sides of the bed are well fixed and not easy to shake.
[0040] In the present invention, a connecting plate 44 is provided between the first bed 4 and the second bed 5 , and a connecting plate 44 is provided outside the first bed 4 and the second bed 5 . Connecting bolts are provided on the connecting plate 44 to complete the connection between the first bed 4 and the second bed 5 .
[0041] In addition, a groove 45 is provided on the side of the first bed 4 and the second bed 5 away from the connecting plate 44, a groove 45 is provided on the inner side of the first bed 4 at one end close to the second bed 5 and an inner side of the second bed 5 at one end close to the first bed 4, a bolt hole 461 is provided on the side of the groove 45 on the first bed 4 close to the second bed 5 and a bolt hole 461 is provided on the side of the groove 45 on the second bed 5 close to the first bed 4, and the fixed connection between the first bed 4 and the second bed 5 can be completed by passing the fixing bolt 46 through the two bolt holes and then tightening it with a nut.
[0042] Of course, the number of the fixing bolt 46 is at least one.
[0043] Furthermore, the first bed 4 and the second bed 5 are both square tubes.
