The diamond pin positioning block 503 is used to limit the ninth outer wall of the long wing protruding workpiece 7. The long wing transverse fixing block 502 is used to limit the sixth outer wall of the long wing protruding workpiece 7.

[0024] The end of the long wing transverse fixing block 502 is fixedly connected with a silicone layer for increasing friction and protecting the workpiece.

[0025] The long wing lower clamping assembly includes a long wing angle cylinder 504 and a long wing lower clamping block 505. The long wing angle cylinder 504 is fixedly connected to the long wing transverse fixing block 502. The long wing lower clamping block 505 is fixedly connected to the output end of the long wing angle cylinder 504.

[0026] The end of the long wing pressure block 505 is fixedly connected with a silicone layer for increasing friction and protecting the workpiece.

[0027] The long-wing lateral side clamping assembly includes a long-wing lateral push cylinder 506 and a long-wing lateral push block 507.

[0030] In this utility model, initially the long wing support rotating block 510 is not on the same plane as the long wing longitudinal support rod 508 and the long wing support push rod 511. When the long wing transverse push cylinder 506 pushes the long wing transverse push block 507 to press against the seventh outer wall of the long wing protruding workpiece 7, one end of the long wing support rotating block 510 abuts against the long wing longitudinal support rod 508, and the other end of the long wing support rotating block 510 abuts against the output end of the long wing support push rod 511. The protrusion of the long-wing protruding workpiece 7 is inserted into the positioning groove 501 of the long-wing transverse placement block 512. The long-wing corner cylinder 504 is activated, causing the long-wing lower pressing block 505 to rotate and press against the eighth outer wall of the long-wing protruding workpiece 7. The long-wing transverse push cylinder 506 is activated, causing the long-wing transverse push block 507 to press against the seventh outer wall of the long-wing protruding workpiece 7. The long-wing transverse fixing block 502 and the long-wing transverse push block 507 cooperate to achieve clamping of the long-wing protruding workpiece 7 in the transverse direction. Fix and activate the long wing support push rod 511. Under the action of the long wing support limiting hole 509 and the long wing support rotating block 510, the long wing support push rod 511 moves away from the long wing protruding workpiece 7, which will drive the long wing longitudinal support rod 508 to move closer to the long wing protruding workpiece 7, so that the end of the long wing longitudinal support rod 508 abuts against the outer wall of the long wing area of ​​the long wing protruding workpiece 7, preventing vibration and deformation of the long wing area of ​​the long wing protruding workpiece 7 during processing.

[0031] Example 2: In some embodiments, as a preferred embodiment of the present invention, different long-wing component clamping mechanisms 5 or other different clamping mechanisms can be installed on the other two sets of liner plates 3 to facilitate the subsequent processing of different types of products.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
