The setting of multiple groups of component limiting shells 2 can support and limit the internal components while ensuring the consistent clamping force on both sides of the workpiece.

[0027] See also Figure 1 and Figure 2 The other side of the component limit housing 2 is rotatably connected to one end of the first linkage plate 9, and the other end of the first linkage plate 9 is rotatably connected to one end of the arc-shaped linkage plate 10. There are two groups of arc-shaped linkage plates 10, and an electric-controlled cylinder 12 is rotatably arranged between the two groups of arc-shaped linkage plates 10. The two groups of arc-shaped linkage plates 10 are symmetrically distributed on both sides of the milling workbench 1. The close cooperation between multiple groups of arc-shaped linkage plates 10 and the first linkage plate 9 can effectively change the direction of force, so that subsequent components move in the direction of the force. The electric-controlled cylinder 12 is a prior art and will not be described in detail. The setting of the electric-controlled cylinder 12 can effectively provide sufficient power support for the movement of subsequent components.

[0028] See also Figure 1 and Figure 2 The bottom of the milling workbench 1 is fixedly connected to the top of the supporting balancing base plate 18, and a screw hole 19 is opened in the middle of the supporting balancing base plate 18. The setting of the screw hole 19 is convenient for the staff to disassemble and assemble the milling fixture at any time and reduce the working time. The groove in the middle of the arc linkage plate 10 is rotatably set in the first fulcrum module 11, and one side of the arc linkage plate 10 is fixedly connected to one end of the second linkage plate 13, and the other end of the second linkage plate 13 is rotatably connected to one end of the third linkage plate 14. The close cooperation between the second linkage plate 13 and the third linkage plate 14 can effectively drive the subsequent components to move and ensure the stability during the movement.

[0029] See also Figure 2 and Figure 4 The other end of the third linkage plate 14 is rotatably arranged in the second fulcrum module 15, one side of the second fulcrum module 15 is fixedly connected to the outer circumferential surface of the linkage control ring 16, the inner wall of the linkage control ring 16 is slidably connected to the outer circumferential surface of the limiting guide single rod 17, and the top of the limiting guide single rod 17 is fixedly connected to the top of the inner wall of the milling worktable 1. The arrangement of the second fulcrum module 15, the linkage control ring 16 and the limiting guide single rod 17 can effectively limit other components, so that the movement efficiency between the two sets of arc-shaped linkage plates 10 remains consistent.

[0030] See also Figure 1One side of the first fulcrum module 11 is fixedly connected to one side of the milling worktable 1, one side of the component limit housing 2 is fixedly connected to one side of the limit guide plate 8, and the limit guide plate 8 is slidably arranged in the groove inside the milling worktable 1. The cooperation between the limit guide plate 8 and the milling worktable 1 can effectively ensure the smooth sliding of other components, so that the two groups of component limit housings 2 can move in the horizontal direction.

[0031] See also Figure 3 A first guide plate 3 is slidably provided inside the component limiting shell 2, a first positioning column 4 is slidably provided in a groove in the middle of the first guide plate 3, the first positioning column 4 is fixedly provided inside the component limiting shell 2, one side of the first guide plate 3 contacts one side of the second guide plate 5, a second positioning column 6 is slidably provided in a groove in the middle of the second guide plate 5, the second positioning column 6 is fixedly provided inside the component limiting shell 2, the first guide plate 3, the first positioning column 4, the second guide plate 5, and the second positioning column 6 are provided, and the telescopic angle can be freely adjusted to realize the clamping of irregular workpieces.

[0032] See also Figure 3 A rubber clamping block 7 is fixedly provided at one end of the second guide plate 5. The setting of the rubber clamping block 7 can avoid excessive clamping and thus damage to the workpiece surface.

[0033] Working principle: Place the workpiece on the milling table 1, start the electric control cylinder 12 to work, push the arc linkage plate 10 to move, the arc linkage plate 10 moves with the intersection of the first fulcrum module 11 as the origin, and push the component limit housing 2 on the first linkage plate 9 to move. Under the action of the limiting guide plate 8, the component limit housing 2 slides horizontally in the groove in the milling table 1. At the same time, the movement of the arc linkage plate 10 will also drive the second linkage plate 13 to move, so that the third linkage plate 14 drives the linkage control ring 16 on the second fulcrum module 15 to move in the limit. The two sets of component limiting shells 2 will make relative movement, gradually contact and clamp the workpiece. At this time, when the rubber clamping block 7 first contacts the workpiece, the second guide plate 5 will push the first guide plate 3 to slide in the component limiting shell 2, and the component limiting shell 2 will push the other set of second guide plates 5 to move until the rubber clamping blocks 7 on the two sets of second guide plates 5 contact the workpiece, thereby effectively clamping the irregular workpiece and increasing the practical effect of the milling fixture.
