Specifically, can make the whole of this processing frock as an organic whole through base 1, convenient transportation. The first base 11 and the second base 12 can support and fix various parts of the tool. The first transverse locating assemblies 21 and the second transverse locating assemblies 31 correspond to the number of workpieces which can be clamped at one time, and the single machining yield can be increased and the production efficiency of the production line can be improved by arranging a plurality of workpieces. One side of the link body and the link cover can be positioned through the first positioning block 212 and the second positioning block 312, and then the other side of the link body and the link cover is fixed through the first propping device 213 and the second propping device 313, so that the positioning of the link body and the link cover in the transverse direction is realized. In the location of fore-and-aft direction, the rear of work piece and the place ahead contact of base, and the both sides of machined part realize compressing tightly through horizontal locating component, consequently need follow the place ahead of machined part and fix a position, because locating component also need install on the base, consequently, this frock realizes rotating through first rotatory compression component 22 and second rotatory compression component 32 and compresses tightly, through prying, makes the one end of branch forward, and then makes the other end of branch compress tightly the work piece. Further, the structure of the connecting rod body tooling 2 and the connecting rod cover tooling 3 is substantially the same, and the difference is that the connecting rod body is provided with a small head, and the tooling positions the small shaft through the positioning mandrel 23, so that the movement of the connecting rod body in the longitudinal direction is limited. The connecting rod cover has no small head capable of being positioned, so that the connecting rod cover needs to be positioned through the upper and lower positioning parts, the tool is longitudinally positioned through the arrangement of the bottom positioning block and the longitudinal pressing piece 33, and the position needing to be processed can be avoided.
As another specific embodiment, a plurality of first transverse positioning assemblies 21 are distributed along a transverse array, and two adjacent first transverse positioning assemblies 21 share one first rotary compression assembly 22; the first base 11 is further provided with a first telescopic cylinder 223 which stretches back and forth, and the rear side of the first compression piece 222 arranged at the two sides is contacted with the first telescopic cylinder 223;

As another specific embodiment, the first positioning block 212 is detachably connected to the first positioning plate 211; the second positioning block 312 is detachably connected with the second positioning plate 311. Because the transverse widths between the connecting rods with different specifications are different, the detachable positioning blocks are adopted, when products with different types are processed, workers directly replace and install the corresponding positioning blocks on the clamp according to the prior process size, alignment is not needed, an adjusting bolt is not needed, and debugging time is saved. Further, the first positioning block 212 and the second positioning hole each include a plurality of positioning block units, and the positioning block units have a plurality of sizes and can be freely combined according to each required size.
As another specific embodiment, the positioning mandrel 23 is detachably connected to the first base 11. By changing different positioning mandrels 23, products of different types can be matched, and the purpose of rapid adjustment is achieved.
As another specific embodiment, a cushion block 4 is further disposed in front of the first positioning plate 211 and/or the second positioning plate 311. The end face of the large hole of the connecting rod and the end face of the small hole of the connecting rod can be located in the same vertical plane through the cushion block 4, and the perpendicularity of the bolt hole to the joint surface is prevented from being influenced. Further, the cushion block 4 is detachably disposed in front of the first positioning plate 211 and/or the second positioning plate 311.

As another specific embodiment, the base 1 has a step, and the link cover fixture 3 is disposed above and behind the link body fixture 2. The front side of the connecting rod cover tool 3 and the front side of the connecting rod body tool 2 are both free of shielding through the steps, and operation during assembly is facilitated. Secondly, since the link body is longer in the longitudinal direction than the link cover, locating the link body tooling 2 below can reduce the longitudinal difference between the processing planes, facilitating handling.
As another specific embodiment, a bottom plate 6 is disposed below the base 1. Because this processing frock is located and is processed on the workstation of lathe, can be responsible for constructing the frame, bearing through bottom plate 6 to set up anchor clamps on the workstation of lathe.
As another specific embodiment, the bottom plate 6 is provided with a jack, and a plug pin 7 is arranged in the jack. The whole tool and the workbench can be limited through the jack and the bolt 7, and the tool is prevented from moving in the processing process. Specifically, the workbench is provided with a t-shaped groove, and the fixing piece penetrates through the insertion hole and is inserted into the t-shaped groove.
As another specific embodiment, a lifting ring 8 is also included. Because the whole set of tool clamp has larger weight, the whole set of tool clamp needs to be lifted and transported to a workbench. Further, the lifting ring 8 is arranged on the bottom plate 6 and the base 1, can bear larger load, does not influence product processing, and can prevent rollover.
