DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present invention provides a variable hydraulic worktable for a laser cutting machine. It includes a hydraulic lifting unit 100. For example, Figure 1 and Figure 2 As shown, the main body of the hydraulic lifting unit 100 is a rectangular frame structure, and a circuit control system 101 is installed on the side wall of the hydraulic lifting unit 100 .

[0040] A correction dust cover 200 is movably installed on the top of the hydraulic lifting unit 100. The correction dust cover 200 is used to correct the height of the platform top.

[0041] A support platform 300 is installed inside the frame of the hydraulic lifting unit 100, and the support platform 300 is transmission-connected to the output end of the hydraulic lifting unit 100. The support platform 300 is used to place the objects to be cut.

[0042] A lifting base 400 is installed below the hydraulic lifting unit 100, a waste residue collection box 700 is installed on the lifting base 400, a telescopic hose 800 is connected to the waste residue collection box 700, and a waste residue collection unit 500 is connected to the top of the telescopic hose 800, and the waste residue collection unit 500 is installed at the bottom of the hydraulic lifting unit 100. The waste residue collection unit 500 is used to collect waste residue generated by laser cutting.

[0043] A group of load-bearing brackets 600 are respectively installed at the edges of the top of the lifting base 400 , and the top of the load-bearing bracket 600 is installed on the hydraulic lifting unit 100 .

[0044] Two sets of side protection plates 900 are installed on the waste residue collection unit 500 , and the side protection plates 900 and the main body of the waste residue collection unit 500 are combined to form a sealed cavity.

[0045] The lifting base 400 includes a base body 410. For example, Figure 2 and Figure 3As shown, the base body 410 is located directly below the main body of the hydraulic lifting unit 100, the waste collection box 700 is installed at the top center of the base body 410, and two sets of side slide rails 420 are symmetrically arranged on both sides of the waste collection box 700. The side slide rails 420 are slidably connected with pulleys 430, and the pulleys 430 are installed with first adjustment rods 440, and the other end of the first adjustment rod 440 is hinged to the bottom of the main body of the waste collection unit 500. The first adjustment rod 440 is hinged to a side wall of the waste collection box 700, and the other end of the second adjustment rod 450 is installed with an anti-slip spring 460, and the other end of the anti-slip spring 460 is installed with a third adjustment rod 470, and the other end of the third adjustment rod 470 is hinged to the top of the base body 410.

[0046] The hydraulic lifting unit 100 includes a main frame 110. For example, Figure 4 As shown, the main frame 110 is a rectangular frame structure, and two sets of steps 120 are symmetrically arranged at the edges of both sides of the top of the main frame 110. The bottom edge of the correction dust cover 200 is movably mounted on the steps 120. A hydraulic motor 130 is installed on the main frame 110. A slideway 140 is provided on the inner wall of the main frame 110 in a vertical direction, and a lifting slider is slidably connected in the slideway 140. One end of the lifting slider is transmission-connected to the output end of the hydraulic motor 130, and the other end is installed on the main body of the support platform 300.

[0047] When the height of the support platform 300 needs to be adjusted, it is only necessary to start the hydraulic motor 130, and the hydraulic motor 130 drives the support platform 300 to rise and fall, thereby realizing the variability of the height of the support platform 300, so that the support platform 300 can cut objects to be cut of different volumes. While the support platform 300 is rising and falling, the waste collection unit 500 will be driven to descend together, so that the first adjustment rod 440 pushes the pulley 430 to slide in the side slide rail 420, and the angle with the base body 410 changes. While the support platform 300 is rising and falling, the second adjustment rod 450 will also be raised and lowered, and the anti-slip spring 460 will be pressed or pulled. After the height adjustment is completed, no matter where the support platform 300 and the waste collection unit 500 are, a triangular structure is formed between the first adjustment rod 440 and the second adjustment rod 450, thereby increasing the bearing capacity of the support platform 300.

[0048] The calibration dust cover 200 includes an upper cover body 210. For example, Figure 5As shown, the upper cover body 210 is movably mounted on the step 120, and the outer walls of the upper cover body 210 are respectively fitted with the inner walls of the main frame 110. The bottom of the correction dust cover 200 is arranged with a plurality of groups of correction grooves 220 at equal intervals along its length direction, and a plurality of groups of correction blocks 230 are arranged at equal intervals in the correction grooves 220. A pressure sensor is installed on the correction block 230, and the pressure sensor is electrically connected to the circuit control system 101. Two adjacent groups of the correction grooves 220 are directly provided with a group of adjustment through grooves 240.

[0049] The support platform 300 includes a platform mounting frame 310. For example, Figure 6 and Figure 7 As shown, the platform mounting frame 310 is located in the overall frame 110 and is mounted on the lifting slider. The platform mounting frame 310 is a rectangular frame structure, and a plurality of groups of bevel gear mounting strips 320 are arranged at equal intervals along the length direction of the platform mounting frame 310, the number of which is the same as the number of the correction slots 220. The bevel gear mounting strips 320 are arranged at equal intervals, the number of which is the same as the number of the correction blocks 230.

[0050] The bevel gear mounting strip 320 includes a mounting strip body 321. Figure 7 and Figure 8As shown, the mounting bar body 321 is movably mounted in the platform mounting frame 310, and a plurality of groups of lifting adjustment chambers 322 having the same number as the supporting bevel gears 350 are arranged at equal intervals in the mounting bar body 321, and a correction opening 360 is provided at the top of the lifting adjustment chamber 322. The bottom of the supporting bevel gear 350 extends into the lifting adjustment chamber 322. A transverse slide 323 is provided at the bottom of the lifting adjustment chamber 322, and a plurality of groups of lower slide fixing grooves 324 are arranged at equal intervals at the bottom of the transverse slide 323 along its length direction. A slider 325 is slidably connected in the transverse slide 323, and a lifting push block 326 is installed on the slider 325. A slope 370 is provided at the top of the lifting push block 326, and the height of the slope 370 at one end close to the supporting bevel gear 350 is lower than that at the other end. The bottom of the supporting bevel gear 350 slides and fits on the slope 370. A connecting rod slot 330 is provided on the side wall of the lifting and adjusting chamber 322, and a connecting rod 327 is slidably connected in the connecting rod slot 330. One end of the connecting rod 327 is mounted on the lifting and pushing block 326, and the other end of the connecting rod 327 extends to the outside of the lifting and adjusting chamber 322, and a hand-pushing block 340 is installed. A linkage rod 328 is provided in the connecting rod 327, and one end of the linkage rod 328 extends into the lifting and pushing block 326, and a first vertical rod is installed at the bottom, and the bottom of the first vertical rod is movably inserted in any set of fixed grooves 324 under the slot. The other end of the linkage rod 328 extends into the hand-pushing block 340, and a second vertical rod is installed at the bottom, and the bottom of the second vertical rod extends to the outside of the hand-pushing block 340. A return spring 329 is installed on the linkage rod 328, and the other end of the return spring 329 is installed on the inner wall at the top of the connecting rod 327.

[0051] The supporting bevel gear 350 includes a bevel gear top rod 351. For example, Fig. 9 and Fig.10 As shown, the bevel gear top rod 351 is inserted into the correction port 360, and the bottom of the bevel gear top rod 351 extends into the lifting adjustment cavity 322 and slides with the inclined surface 370. A bevel gear body 352 is installed on the top of the bevel gear top rod 351. The bevel gear body 352 is a quadrangular pyramid structure, and the top of the bevel gear body 352 movably contacts a corresponding set of correction blocks 230. Two groups of top grooves 353 are symmetrically opened on the two side walls of the bevel gear body 352 parallel to the width direction of the bevel gear mounting strip 320, and a plurality of groups of lower sliding grooves 354 are arranged at equal intervals at the bottom of the top groove 353. The bottom of the lower sliding groove 354 is an open structure, and a seesaw 355 is installed at the opening. The cross section of the seesaw 355 is a fan ring, and the bottom of the seesaw 355 extends upward.

[0052] After the support platform 300 is used for a long time, the top of each group of bevel gear bodies 352 may be softened and deformed easily due to the high temperature of the laser cutting head, thereby causing the tops of each group of bevel gear bodies 352 to be not at the same height.

[0053] First, the upper cover body 210 is covered on the top of the overall frame 110, and then the hydraulic motor 130 is started to drive the support platform 300 to rise as a whole. When one or more groups of pressure sensors simultaneously sense the pressure on the top of the bevel gear body 352, the hydraulic motor 130 is turned off, and then each group of pressure sensors uploads the pressure value to the circuit control system 101. When the pressure value of the pressure sensor is zero, it is determined that the top height of the group of bevel gear bodies 352 corresponding to the group of pressure sensors is lower than that of other groups. Then, the hand is inserted into the middle cavity of the platform mounting frame 310 through the corresponding group of adjustment slots 240, and the corresponding group of second vertical rods is pressed upward to drive the linkage rod 328 and the first vertical rod to rise, and the bottom of the first vertical rod is separated from the corresponding group of lower fixed slots 324 of the slide groove. Then, the hand push block 340 is held and pushed to one side of the bevel gear top rod 351, and the bevel gear top rod 351 is raised by using the sliding fit relationship between the inclined surface 370 and the bevel gear top rod 351 until the pressure value is transmitted by the group of pressure sensors. Then, the second vertical rod is loosened, and under the action of the return spring 329 , the first vertical rod descends and is inserted into a corresponding set of lower fixing grooves 324 of the slide grooves, thereby limiting the height of the bevel gear body 352 .

[0054] First, the height of the top of each group of bevel gear body 352 is detected by each group of correction blocks 230. When a bevel gear body 352 with a lower height appears, the hand push block is moved to drive the lifting push block 326 to move horizontally to the side of the bevel gear top rod 351. The sliding fit relationship between the inclined surface 370 and the bevel gear top rod 351 is used to make the bevel gear body 352 rise, meeting the need to adjust the overall height of the supporting bevel gear 350. The object to be cut will not tilt or one end will be suspended, reducing the influence of the support platform 300 on the cutting accuracy, thereby improving the cutting effect. The adjustment work is simple and quick, and there is no need to disassemble the platform.

[0055] During laser cutting, a lot of high-temperature waste residues will be generated. These waste residues fall into the gap between two adjacent groups of supporting bevel teeth 350 and are difficult to clean. By setting the top groove 353 and the lower groove 354, the high-temperature waste residues can slide down along the top groove 353 and the lower groove 354, and finally fall to the waste residue collection unit 500 below through the seesaw 355. This not only prevents the high-temperature waste residues from splashing around and causing harm to the staff, but also prevents the high-temperature waste residues from accumulating in the gap between two adjacent groups of supporting bevel teeth 350, and there is no need to clean the supporting bevel teeth 350. This reduces the intensity and time of later maintenance.

[0056] The waste residue collection unit 500 includes two sets of collection plates 510. For example, Fig.11 , Fig.12 and Fig.13As shown, the tops of the two groups of collecting plates 510 are symmetrically mounted at the bottom edges of the two side walls in the width direction of the platform mounting frame 310. The bottoms extend obliquely in opposite directions, and a middle seat 520 is provided at the joint of the bottoms of the two groups of collecting plates 510. The cross section formed by the combination of the middle seat 520 and the two groups of collecting plates 510 is an inverted triangle structure. The two groups of side protection plates 900 are symmetrically mounted at the openings on both sides of the inverted triangle structure. Several groups of convex strips 511 are evenly spaced along the width direction of the collecting plate 510, and several groups of convex strip anti-spout ports 513 are evenly spaced along the length direction of the convex strips 511. A group of waste residue inlet 512 is provided between two adjacent groups of convex strips 511, and the width of the waste residue inlet 512 near one end of the inner cavity of the collecting plate 510 is smaller than the width of the other end. Several groups of waste residue discharge ports 514 are evenly spaced on the inner wall of one side wall of the collecting plate 510 near the middle seat 520. On the two side walls of the middle seat 520 close to the collecting plate 510, there are arranged at equal intervals a number of groups of sloped slag inlets 550, the same number as the waste slag discharge openings 514. Each group of the sloped slag inlets 550 is connected to a corresponding group of waste slag discharge openings 514. A slag discharge opening 530 is opened at the center of the bottom of the middle seat 520, and two groups of slopes 540 are symmetrically arranged on both sides of the slag discharge opening 530, and the bottom of the slag discharge opening 530 is connected to the telescopic hose 800.

[0057] After the waste residue falls onto the collecting plate 510, no matter where it falls, it can enter the cavity of the collecting plate 510 through the waste residue inlet and the convex anti-spout port 513, and the width of the bottom of the waste residue inlet 512 is smaller than the width of the top, so that the waste residue will not bounce out after entering the cavity of the collecting plate 510. Then, it enters the middle seat 520 through each group of waste residue discharge ports 514, and finally is discharged into the waste residue collection box 700 through the discharge port 530 and the telescopic hose 800. No manual control is required throughout the process, and the waste residue is prevented from splashing everywhere and being difficult to collect.

[0058] By utilizing the inverted triangle structure formed by the middle seat 520 and the two sets of collecting plates 510, and the triangle structure formed by the first adjusting rod 440 and the second adjusting rod 450, the stability of the waste collection unit 500 and the supporting platform 300 is increased, and the bearing capacity of the supporting platform 300 is also improved.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
