[0067] In addition, the support portion 122 includes the floating support column 1221, and the floating support column 1221 is disposed through the connecting portion 121. In this embodiment, the workpiece 101 to be processed is supported by the support portion 122, that is, the unevenness of the workpiece 101 is compensated by the floating support column 1221, thereby achieving effective and stable support for the workpiece 101.

[0068] Alternatively, if Figure 3 As shown, the connecting portion 121 includes a first connecting plate 1211 and a second connecting plate 1212 .

[0069] The first connecting plate 1211 is disposed in the first accommodating cavity 113 , and the first connecting plate 1211 is connected to the inner wall of the surrounding edge 112 , and the connection method is, for example, welding.

[0070] In addition, the second connecting plate 1212 is disposed on a side of the first connecting plate 1211 away from the bottom plate 111 , and the second connecting plate 1212 is connected to the inner wall of the surrounding edge 112 , and the connection method is, for example, welding.

[0071] Optionally, the floating support column 1221 is sequentially disposed in the first connecting plate 1211 and the second connecting plate 1212 , and can float between the first connecting plate 1211 and the second connecting plate 1212 .

[0072] Specifically, the first connecting plate 1211 has a first through hole, and the second connecting plate 1212 has a second through hole.

[0073] Optionally, the first through hole and the second through hole are arranged in a one-to-one correspondence, and an axis of the first through hole coincides with an axis of the second through hole.

[0074] It should be noted that this embodiment does not limit the number of the first through holes and the second through holes. On the premise of ensuring that the first through holes and the second through holes are arranged one-to-one, the specific numbers of the first through holes and the second through holes can be designed according to actual production conditions.

[0075] Optionally, in this embodiment, the number of the first through hole and the number of the second through hole are both, for example, 200. The floating support columns 1221 are disposed in the corresponding first through hole and the second through hole, so the number of the floating support columns 1221 corresponds to the number of the first through hole and the second through hole one by one, that is, when the number of the first through hole and the second through hole are both, for example, 200, the number of the floating support columns 1221 is also, for example, 200.

[0076] It should be noted that this embodiment does not limit the number of the floating support columns 1221 , and the number of the floating support columns 1221 can be designed according to actual production conditions.

[0077] Alternatively, if Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the first accommodating chamber 113 is divided into a second accommodating chamber 1131 and a third accommodating chamber 1132 by the first connecting plate 1211 .

[0078] The second accommodating cavity 1131 is located between the first connecting plate 1211 and the bottom plate 111, and the third accommodating cavity 1132 is located between the second connecting plate 1212 and the first connecting plate 1211. It should be noted that the second accommodating cavity 1131 is not connected to the third accommodating cavity 1132.

[0079] Optionally, the support base 110 of this embodiment further has a first connection hole 1125 and a second connection hole 1126 .

[0080] The first connection hole 1125 is disposed on the surrounding edge 112 , and the first connection hole 1125 is communicated with the second accommodating cavity 1131 .

[0081] In this embodiment, the second accommodating chamber 1131 is connected to an external air source through the first connecting hole 1125, so that external air can be injected into the second accommodating chamber 1131 through the first connecting hole 1125, and an air pressure chamber is formed in the second accommodating chamber 1131, and then the air pressure of the air pressure chamber supports the floating support column 1221 to float in a direction away from the base plate 111, thereby supporting the floating support column 1221 away from the workpiece 101 at one end of the base plate 111, and making the end of the support column away from the base plate 111 contact the workpiece 101, thereby effectively compensating for dimensional deviations and uneven defects in the product appearance.

[0082] Optionally, the inner wall of the first connection hole 1125 has threads, so the external gas source is connected to the support seat 110 through threads.

[0083] Alternatively, if Figure 3and Figure 4 As shown, the connecting portion 121 further includes a fixing sleeve 1213 .

[0084] Among them, the fixed sleeve 1213 is arranged between the first connecting plate 1211 and the second connecting plate 1212, and one end of the fixed sleeve 1213 is connected to the first connecting plate 1211, and the end of the fixed sleeve 1213 away from the first connecting plate 1211 is connected to the second connecting plate 1212, and the connection method is, for example, brazing.

[0085] Specifically, the fixing sleeve 1213 is in communication with the first through hole, the second through hole and the second accommodating cavity 1131. In this embodiment, the supporting portion 122 is clamped by the fixing sleeve 1213.

[0086] Optionally, the floating support column 1221 is sequentially inserted into the second through hole, the fixed sleeve 1213 and the first through hole. The end of the floating support column 1221 away from the bottom plate 111 may protrude from the second connecting plate 1212, and the floating support column 1221 may freely float close to or away from the bottom plate 111, thereby realizing free adjustment of the contact point.

[0087] Alternatively, if Figure 4 As shown, the support portion 122 also includes a limiting plate 1222, which is arranged at one end of the floating support column 1221 close to the bottom plate 111, and the limiting plate 1222 is located in the second accommodating cavity 1131, that is, the limiting plate 1222 is located on the side of the first connecting plate 1211 away from the second connecting plate 1212.

[0088] In this embodiment, the floating of the floating support column 1221 is limited by the limiting plate 1222 , thereby preventing the floating support column 1221 from being separated from the connecting portion 121 .

[0089] It should be noted that this embodiment does not limit the length of the floating support column 1221, and the specific length of the floating support column 1221 can be designed according to actual production conditions.

[0090] Specifically, in this embodiment, the floating support column 1221 is clamped and fixed by the fixing sleeve 1213 , so that the floating support column 1221 does not move, so that the supporting device 100 of this embodiment can stably support the workpiece 101 .

[0091] Optionally, the fixed sleeve 1213 is made of a material with lower hardness than the floating support column 1221 and with certain toughness and protection, so as to provide a certain supporting force for the floating support column 1221 without damaging the floating support column 1221 .

[0092] In addition, the second connection hole 1126 of the support seat 110 is disposed on the peripheral edge 112 , and the second connection hole 1126 is located on a side of the first connection hole 1125 away from the bottom plate 111 . The second connection hole 1126 is communicated with the third accommodation cavity 1132 .

[0093] Specifically, in this embodiment, the third accommodating chamber 1132 is connected to the external hydraulic mechanism through the second connecting hole 1126, that is, the external hydraulic mechanism injects its liquid into the third accommodating chamber 1132 through the second connecting hole 1126, and the third accommodating chamber forms a hydraulic chamber, and then the fixed sleeve 1213 is pressed by the hydraulic pressure of the hydraulic chamber, so that the fixed sleeve 1213 clamps and fixes the floating support column 1221, which helps to improve the strength and stability of the floating support column 1221.

[0094] In this embodiment, when the air pressure chamber makes the floating support column 1221 float, when the end of the floating support column 1221 away from the base plate 111 contacts and supports the workpiece 101, the floating support column 1221 is clamped and fixed by the fixed sleeve 1213 to prevent the floating support column 1221 from shaking when the workpiece 101 is processed.

[0095] It should be noted that there are multiple floating support columns 1221 in this embodiment, and the multiple floating support columns 1221 can float at different distances according to the flatness difference of the workpiece 101, so as to effectively and stably support the workpiece 101.

[0096] This embodiment ensures the stability of the support force during the entire processing of the workpiece 101 by means of gas pressure stabilization and hydraulic pressure application, prevents tool vibration, improves product quality, and can compensate for the influence of the fulcrum change after tool wear in a short period of time, ultimately ensuring the processing accuracy of the workpiece 101. The support device 100 of this embodiment has a simple structure and is easy to implement.

[0097] This embodiment provides a processing device having the supporting device 100 described in any of the above embodiments, and thus having all the beneficial effects of the supporting device 100, which will not be described in detail here.
