As shown in the figure, as a further structure, a cylinder seat 9 is fixed on the bottom plate 7, and the cylinder seat 9 is hinged with the end part of the driving cylinder 5, so that the driving cylinder 5 is prevented from self-locking when the driving pressure plate 4 rotates.

As shown in the figure, as a further structure, a gap 10 is arranged on the compressing end of the pressure plate 4; the panel 6 is provided with a positioning boss 11, the positioning clamping block 3 is placed on the positioning boss 11, and the structure avoids that the surface contact with the positioning clamping block 3 is too large, the contact surface is too large and is not easy to ensure the flatness and the smoothness of the whole plane, so that the processing difficulty is improved, certainly, the processing difficulty cannot be too small, and the clamping is unstable too small.

As shown in the figure, as a further structure, the panel 6 is provided with a positioning pin 12, and the positioning clamping block 3 is provided with a positioning hole 13 matched with the positioning pin 12, because the processing of the workpiece 2 is three-dimensional processing, the workpiece 2 needs to be positioned on the panel 6 through the positioning pin 12.

As a further structure: the locating pin hole matched with the locating pin 12 is formed in the panel 6, the clamp frame comprises a side plate 15 and a hollowed hole 14, the side plate 15 is arranged on the bottom plate 7 and supports the panel 6, the hollowed hole 14 is formed in the side plate 15, a supporting column hole and a locking screw hole communicated with the supporting column hole are formed in the side plate 15, one end of the supporting column hole is communicated with the side plate 15, the other end of the supporting column hole is communicated with the hollowed hole 14, the supporting column hole is communicated with the locating pin hole in an overlapping mode, a locking column 16 is arranged in the supporting column hole, the locking column 16 is locked through a screw 17 matched with the locking screw hole, the locking column 16 can support the locking locating pin 12, the locating pin hole is a countersunk hole, a pin cap 18 matched with the countersunk hole is arranged at the end of the locating pin 12, and the locking column 16 fixes the locating pin 12 by locking the pin cap 18 in the countersunk hole. The purpose of the above structure is to facilitate the replacement of the positioning pin 12, so that the positioning pin 12 is fixed by the matching of the pin cap 18 and the countersunk hole, and then the locking post 16 is used for jacking the pin cap 18 to fix the positioning pin 12, and the locking post 16 is locked by the screw 17 on the side surface, so that when the positioning pin 12 needs to be replaced, only the screw 17 needs to be loosened from the processing hole 8, then the tail end of the locking post 16 exposed out of the hollowed hole 14 on the side plate 15 is clamped by a hand or a clamp, the locking post 16 can be pulled out, and then the positioning pin 12 can be knocked out by a tool. Since the insert pin for forming the positioning hole 13 is worn after multiple times of injection molding, the diameter of the rear positioning hole 13 is reduced, and the positioning pin 12 with the end corresponding to the diameter of the rear positioning hole 13 needs to be replaced, otherwise the positioning pin 12 is difficult to insert into the positioning hole 13, and the positioning error is large.

After the clamp with the structure is used for machining, the conventional clamp clamping workpiece 2 can be replaced, and the positioning clamping block 3 is milled, because the position of the positioning clamping block 3 is a non-machining position, the use and the precision of the workpiece 2 are not affected after the positioning clamping block 3 is milled, and therefore the positioning clamping block 3 plays a role in machining transition.

The above detailed description is given to the clamping system for processing the special-shaped workpiece 2 provided by the embodiment of the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
