The clamping and supporting processing fixing mechanism 10 can realize automatic positioning and fixing without clamping by using a lock screw, and has high operation efficiency and low maintenance cost of the jig.

In an embodiment, the bearing portion 13 is provided with a first through hole 131, the first through hole 131 is disposed corresponding to the mounting station 132, the pressing plate 14 is provided with a second through hole 142, and the second through hole 142 is disposed corresponding to the first through hole 131.

It will be appreciated that the main connecting portion 12 is also correspondingly provided with a third through hole 123, the third through hole 123 is correspondingly provided with the first through hole 131 and the second through hole 142, and in the extending direction along the pull rod 152, one first through hole 131, one second through hole 142 and one third through hole 123 correspondingly penetrate, so that the pull rod 152 can sequentially pass through the main connecting portion 12, the bearing portion 13 and the pressing plate 14, and the end of the pull rod 152 far from the cylinder body 151 is located on the side of the pressing plate 14 far from the bearing portion 13.

In an embodiment, the pull rod 152 includes a rod 1521 and a locking block 1522, the locking block 1522 is connected to a top end of the rod 1521 away from the cylinder body 151, the rod 1521 passes through the first through hole 131 and the second through hole 142, and the locking block 1522 is located on a side of the platen 14 away from the bearing portion 13.

In one embodiment, the locking block 1522 has different widths in at least two directions, the second through hole 142 has different inner diameter lengths in at least two directions, and the cylinder body 151 is configured to rotate the pull rod 152, so that the locking block 1522 can be switched between a state of being able to pass through the second through hole 142 and being locked with the second through hole 142.

In this embodiment, the main connecting portion 12 may have a rectangular parallelepiped shape, and the projection of the locking block 1522 and the second through hole 142 on the large surface of the main connecting portion 12 may have patterns with different side lengths, such as oval, rectangle, diamond, etc., and the projection of the second through hole 142 is slightly larger than the projection of the locking block 1522. This means that when the locking block 1522 is placed in the second through hole 142, the long side of the locking block 1522 corresponds to the long side of the second through hole 142, the short side of the locking block 1522 corresponds to the short side of the second through hole 142, the locking block 1522 can pass through the second through hole 142 by the driving of the rod 1521, and when the locking block 1522 is placed in the second through hole 142, the long side of the locking block 1522 does not correspond to the long side of the second through hole 142, the long side of the locking block 1522 cannot pass through the narrower region of the second through hole 142, and the locking block 1522 is locked by the peripheral plate 141 surrounding the second through hole 142 on the platen 14, and the locking block 1522 cannot pass through the second through hole 142.

The locking state of the locking block 1522 and the second through hole 142 means that another relative placement position exists between the locking block 1522 and the second through hole 142, such that the locking block 1522 cannot pass through the second through hole 142 and is locked by the peripheral plate body 141 surrounding the second through hole 142 on the platen 14, thereby driving the platen 14 to move. In this embodiment, the peripheral plate 141 is recessed toward the side of the bearing portion 13 with respect to the other area of the pressing plate 14, for improving the pressing effect.

The corresponding assembling process may be that the cylinder body 151 rotates the rod 1521 to adjust the placement position of the locking block 1522, so that the locking block 1522 is in a state of being able to pass through the second through hole 142, the rod 1521 passes through the bearing portion 13 through the first through hole 131 and passes through the pressing plate 14 through the second through hole 142, the locking block 1522 is located at one side of the pressing plate 14 away from the bearing portion 13, and then the cylinder body 151 rotates the rod 1521 to adjust the placement position of the locking block 1522, so that the locking block 1522 is staggered from the second through hole 142, the cylinder body 151 drives the rod 1521 to move downward, the locking block 1522 cannot pass through the second through hole 142, the locking block 1522 abuts against the surface of the pressing plate 14 away from the bearing portion 13, and further drives the pressing plate 14 to move towards the bearing portion 13 until the blank 2 is pressed. Subsequently, the cylinder body 151 may be rotated again to rotate the rod 1521 to adjust the placement position of the locking block 1522, thereby releasing the locking of the locking block 1522 to the platen 14, and removing the platen 14 and then removing the finished product and replacing the blank 2.

Furthermore, the clamping and supporting processing and fixing mechanism 10 does not need to use the traditional locking screw for clamping and fixing, and the cylinder body 151 drives the pull rod 152 to pull back and tighten to enable the pressing plate 14 to be pressed on the surface of the bearing part 13 provided with the mounting station 132, so that automatic and rapid fixing is realized, and the operation efficiency is higher. Meanwhile, the screw locking assembly is omitted, the complicated process of disassembling the locking screw is not required, the screw hole teeth are prevented from being damaged due to repeated disassembly and assembly, and the maintenance cost of the clamping and supporting processing fixing mechanism 10 is reduced.
