[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] Reference Figures 1 to 3 The large workpiece support device of the embodiment of the present invention comprises a box assembly 100 and a support rod 500 installed on the box assembly 100. The support rod 500 is installed on the box assembly 100 and is used to support the workpiece. Figure 1 , Figure 2 As shown, the box assembly 100 has a plurality of mounting holes 210, which are arranged in an array, and the length extension direction of the mounting holes 210 is the vertical direction, and the first elastic member 600 is installed in each of the plurality of mounting holes 210. A plurality of support rods 500 correspond to the plurality of mounting holes 210 one by one; the first end of the support rod 500 in the length direction is slidably and sealedly installed in the mounting hole 210 to separate the mounting hole 210 into a first chamber 211 and a second chamber 212, and the first elastic member 600 is installed in the first chamber 211 and abuts against the first end of the support rod 500 in the length direction; the first chamber 211 is also connected to an air supply and exhaust device, and the second end of the support rod 500 in the length direction extends out of the upper surface of the box assembly 100. That is to say, when the support rod 500 supports the workpiece, since each support rod 500 is independent of each other and each support rod 500 is provided with a first elastic member 600 to support it, when workpieces of various shapes are placed on the support rod 500, the height to which each support rod 500 descends is inconsistent, that is, multiple support rods 500 can match a shape similar to the workpiece.

[0040] Furthermore, since the first end of the support rod 500 in the length direction is slidably and sealedly installed in the mounting hole 210, the first chamber 211 and the second chamber 212 are not connected to each other, and the air supply and exhaust device can supply air to the first chamber 211 or extract the air in the first chamber 211; if the air supply and exhaust device supplies compressed air to the first chamber 211, it can push the support rod 500 to rise, and if the air supply and exhaust device extracts the air in the first chamber 211, it can drive the support rod 500 to descend. Therefore, when the support rod 500 supports the workpiece, if accessories are installed on the surface of the workpiece, the support device of this embodiment can be placed under the workpiece in advance for pre-support to obtain the support rod 500 corresponding to the accessories installed on the surface of the workpiece, and then the air in the first chamber 211 is extracted by the air supply and exhaust device to push the support rod 500 to descend, thereby achieving support for the workpiece without damaging the accessories.

[0041] In an embodiment of the present invention, the second end of the support rod 500 in the length direction is connected to a support structure 510, and the support structure 510 is detachably connected to the support rod 500, such as a threaded connection, etc.; the support structure 510 is made of a flexible material, such as plastic or rubber, and the support structure 510 is provided mainly to reduce damage to the surface of the workpiece.

[0042] In an embodiment of the present invention, the box assembly 100 includes a box structure 200 and an intermediate plate 300, and the mounting hole 210 is arranged in the box structure 200. The mounting hole 210 penetrates the box structure 200 in the vertical direction, and the mounting hole 210 is a variable diameter hole, including a wide diameter section and a narrow diameter section; the first end of the support rod 500 in the length direction is provided with a radially protruding sealing ring 520, and the sealing ring 520 is slidably and sealingly installed in the wide diameter section and is sealed and connected to the inner side wall of the wide diameter section. The aperture of the narrow diameter section of the mounting hole 210 is smaller than the aperture of the wide diameter section, and a shoulder is formed at the connection between the wide diameter section and the narrow diameter section, and the shoulder can be abutted against the sealing ring 520 to prevent the support rod 500 from detaching from the mounting hole 210.

[0043] In the embodiment of the present invention, the middle plate 300 is provided with a plurality of positioning blocks 310, and the plurality of positioning blocks 310 correspond to the plurality of mounting holes 210 one by one; the positioning blocks 310 are embedded in the mounting holes 210 and are sealed and connected to the mounting holes 210, and the two ends of the first elastic member 600 are respectively against the positioning blocks 310 and the first end of the length direction of the support rod 500. For details, refer to Figure 2 , Figure 3 As shown, the diameter of the positioning block 310 is the same as the diameter of the wide diameter section of the mounting hole 210, and a sealing ring is installed on the outer peripheral side of the positioning block 310; the positioning block 310 is embedded in the bottom of the wide diameter section of the mounting hole 210, and the two ends of the first elastic member 600 are respectively against the sealing ring 520 and the positioning block 310. The first elastic member 600 is preferably a spring.

[0044] In the embodiment of the present invention, a second elastic member, such as a spring, may also be provided in the second chamber 212; the second elastic member is sleeved on the outer circumference of the telescopic rod, and the two ends of the second elastic member are respectively connected to the box structure 200 and the first end of the length direction of the support rod 500. Specifically, the purpose of providing the second elastic member is to increase the power to push the support rod 500 to reset, so that the support rod 500 can support a larger mass of workpiece.

[0045] It should be noted that the two ends of the first elastic member 600 do not need to be connected to the sealing ring 520 and the positioning block 310, but only need to abut against each other, while the two ends of the second elastic member must be connected to the box structure 200 and the first end of the support rod 500 in the length direction, so as to play the role of pushing the support rod 500 to reset.

[0046] In the embodiment of the present invention, the positioning block 310 is provided with a through hole 311 penetrating the middle plate 300, and the exhaust device is connected to the through hole 311. Figure 2 , Figure 3 As shown, the box assembly 100 also includes a bottom plate 400, which is connected to the middle plate 300; the bottom plate 400 is provided with an external connection hole 410, and the external connection hole 410 is installed with a control valve, which is connected to the through hole 311 through a sealing tube, and the air supply and exhaust equipment is connected to the control valve; there are multiple external connection holes 410, and multiple control valves are connected to multiple through holes 311 in a one-to-one correspondence. The control valve is more convenient to connect with the air supply and exhaust equipment, and the control valve also plays a role in controlling the connection between the first chamber 211 and the outside atmosphere; for example, when the support device of this embodiment is pre-aligned with the workpiece, the control valve is opened to connect the first chamber 211 with the outside atmosphere, so that when the support rod 500 descends, it will only be subject to the resistance generated by the deformation of the first elastic member 600, but not the resistance of the compressed air, ensuring that the height of the support rod 500 descending can better fit the shape of the workpiece.

[0047] In the embodiment of the present invention, a receiving chamber 420 is formed between the bottom plate 400 and the middle plate 300, a sealing tube is arranged in the receiving chamber 420, and an external connection hole 410 is arranged on a side wall of the receiving chamber 420. Specifically, the sealing tube is not shown in the figure, and the sealing tube is made of a flexible material, and the specific model can be a tube that meets the pressure requirements on the market; since there are multiple first chambers 211 and each first chamber 211 is connected to a sealing tube, the number of sealing tubes is relatively large, and the receiving chamber 420 can also be provided with some cable ties, card slots and other structures to facilitate the standardization of the sealing tubes.

[0048] Furthermore, the external connection hole 410 is arranged on the side wall of the accommodating chamber 420, which can facilitate the installation and maintenance of the control valve, and also facilitate the external connection of the air supply and exhaust equipment.

[0049] In the embodiment of the present invention, the middle plate 300 is connected to the box structure 200 by fasteners. Figure 1 , Figure 2 As shown, the edge of the middle plate 300 is provided with a rib extending upward, the outer surface of the box structure 200 is provided with a threaded hole, the rib is provided with a through hole corresponding to the threaded hole, and the rib and the box structure 200 are connected by fasteners such as bolts.

The telescopic structure 700 is installed below the box assembly 100, and the telescopic structure 700 is used to push the box assembly 100 up and down. Specifically, the travel wheel 430 and the telescopic structure 700 are both connected to the bottom plate 400, the middle plate 300 is arranged between the bottom plate 400 and the box structure 200, and the travel wheel 430 and the telescopic structure 700 are installed on the side of the bottom plate 400 away from the middle plate 300. The travel wheel 430 is preferably a universal wheel, and a plurality of travel wheels 430 are provided, and the plurality of travel wheels 430 are generally preferably four or more; a reinforcement plate 440 is provided at the center of the bottom plate 400, and the telescopic structure 700 is connected to the reinforcement plate 440; a plurality of travel wheels 430 are provided, and the plurality of travel wheels 430 are evenly spaced around the outer periphery of the reinforcement plate 440.
