[0030] Combined with Figures 1 to 5 As shown, a balance bed structure of a fiber laser cutting machine provided by the present utility model mode includes a hydraulic push rod 1 and a connecting pipe 2.
[0031] Combined with Figures 1 to 5 As shown, the hydraulic push rods 1 are evenly distributed under the bed plate. The driving end of each hydraulic push rod 1 is universally connected to the bottom surface of the bed plate. Each hydraulic push rod 1 is only provided with one liquid inlet and outlet 121; the connecting pipe 2 simultaneously communicates with all the liquid inlets and outlets; the liquid in all the hydraulic push rods 1 is connected into one piece to jointly support the bed plate.
[0032] In this embodiment, the hydraulic push rods 1 interconnected by the connecting pipe 2 support the bed plate. The internal pressures of the interconnected hydraulic push rods 1 are the same. The liquid tops in the multiple hydraulic push rods 1 automatically tend to be on the same plane, and the automatic adjustment of the levelness of the bed body is realized through the principle of hydraulic transmission, with high adjustment accuracy and low adjustment failure rate.
[0033] In some embodiments, combined with Figure 1 As shown, the number of the hydraulic push rods 1 is at least 3, and the hydraulic push rods 1 are distributed in at least two directions. At least three points not on the same straight line can determine a plane, ensuring the supporting effect of the hydraulic push rods 1 on the plane where the bed plate is located.
[0034] In some embodiments, combined with Figure 2 As shown, the hydraulic push rod 1 includes a push rod 11 and a hydraulic cylinder 12. One end of the push rod 11 is universally connected to the bottom surface of the bed plate, and the other end of the push rod 11 is slidably assembled in the hydraulic cylinder 12. The hydraulic cylinder 12 is integrally formed with a liquid inlet and outlet 121 communicating with the inner cavity.
[0035] In this embodiment, the structure of the hydraulic cylinder 12 is different from the common structure. The difference is that the hydraulic cylinder 12 is only provided with one liquid inlet and outlet 121. When the liquid enters, the hydraulic cylinder 12 extends, and when the liquid flows out, the hydraulic cylinder 12 retracts. The universal connection can ensure the adjustment ability of the hydraulic push rod 1 to the levelness of the bed board.
[0036] In some embodiments, as shown in Figure 2 the vent hole 122 is integrally formed on the hydraulic cylinder 12. The vent hole 122 communicates with the inner cavity. The vent hole 122 and the liquid inlet and outlet 121 are respectively located on both sides of the sliding assembly end of the push rod 11. The sliding assembly end of the push rod 11 only contacts the liquid on one side. The vent hole 122 can discharge the air on the other side to avoid the generation of negative pressure caused by air compression.
[0037] In some embodiments, as shown in Figure 2 a cushion block 111 is fixedly connected to the sliding assembly end of the push rod 11. The side of the cushion block 111 is hermetically fitted with the inner cavity surface of the hydraulic cylinder 12. The sliding assembly end of the push rod 11 generally is also hermetically fitted with the inner cavity surface of the hydraulic cylinder 12. After adding the cushion block 111, a double-layer seal is formed, and the sealing effect is better. At the same time, by changing the thickness of the cushion block 111, the extending position of the push rod 11 can be adjusted, and the influence of the production tolerance of the push rod 11 on the levelness can be reduced.
[0038] In some embodiments, as shown in Figure 3 the balanced bed body structure of the fiber laser cutting machine further includes a universal connector 3. The universal connector 3 includes a connecting ball 31 and a connecting sleeve 32. The connecting ball 31 and the connecting sleeve 32 are connected by a spherical universal joint. The connecting ball 31 is fixedly connected to the hydraulic push rod 1, and the connecting sleeve 32 is fixedly connected to the bed board. The selection of the universal connector 3 will also affect the final levelness of the bed board. The universal connection realized by a single structure has more dimensional changes compared with the universal connection realized by multiple structures, which is beneficial to improving the stability.
[0039] In some embodiments, as shown in Figure 4 and Figure 5 the balanced bed body structure of the fiber laser cutting machine further includes a communicating vessel 4. The communicating vessel 4 is provided with an inner cavity and connecting ports. The number of the connecting ports is equal to the number of the hydraulic push rods 1. Each hydraulic push rod 1 is connected to one of the connecting ports through a connecting pipe 2. All the connecting ports communicate with the inner cavity of the communicating vessel 4. Using the communicating vessel 4 can make the lengths of the connecting pipes 2 between any two hydraulic push rods 1 the same, ensuring the uniformity of the liquid transmission pressure.
[0040] In some embodiments, as shown in Figure 4 and Figure 5As shown, a locking valve 41 is assembled in the communicating vessel 4. The locking valve 41 synchronously controls the communication relationship between each connection port and the inner cavity. The locking valve 41 can cut off the communication relationship between the hydraulic push rods 1 after the bed board is leveled, fix the state of each hydraulic push rod 1, and realize fixing the bed board to the horizontal position.
[0041] In some embodiments, in combination with Figure 4 、 Figure 5 As shown, the communicating vessel 4 is further assembled with a hydraulic pump 42. The oil outlet of the hydraulic pump 42 communicates with the inner cavity. The hydraulic pump 42 can control the total amount of liquid in the communicating state to realize adjusting the vertical height of the bed board.
[0042] In some embodiments, in combination with Figure 1 As shown, the balanced bed body structure of the fiber laser cutting machine further includes a bubble level 5. The bubble level 5 is fixedly connected to the bed board. The bubble level 5 includes more than two bubble glass tubes with different directions. The function of the bubble level 5 is to help the operator judge whether the bed board is level and help the operator judge the timing of using the above-mentioned locking valve 41.
[0043] Working process: When the bed board is in an inclined state, the height of the liquid in the hydraulic push rod 1 on the higher side of the bed board is also higher. The connecting pipes 2 connect the hydraulic push rods 1 to make the liquid in the hydraulic push rods 1 connected as a whole. The high liquid will automatically flow to the low place, so that the liquid heights in the hydraulic push rods 1 are equal. The liquid height in the hydraulic push rod 1 determines the height of the driving end of the hydraulic push rod 1, and the bed board is automatically adjusted to the horizontal position.
[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
