[0002] Modern manufacturing machinery parts processing cannot be separated from lathe, and tool fixture is one of important process equipment for ensuring machining quality, improving production efficiency, reducing labor intensity, reducing the over-high requirement for worker's technology and realizing production process automation, so tool fixture is widely used in manufacturing industry.

[0003] For some complex shape structure, design size precision requirement is higher, often need to design special fixture to control size machining precision. The existing irregular mechanical part needs to be drilled and bored, and needs to be processed by numerical control lathe. If the general fixture is used, the center position of the part drilled and bored is not accurate, the clamping force is uneven, and the operation is not convenient. In view of the defects of the prior art, the utility model provides a special fixture for drilling and boring irregular parts, which can ensure the accurate positioning and firm clamping of the parts during drilling and boring operation, so as to ensure the machining precision and quality. SUMMARY

[0004] The utility model discloses in order to solve the defects and insufficient of prior art, provide a kind of special fixture for drilling and boring irregular parts with simple structure, easy installation, convenient to use, can effectively improve the reliability of work.

[0005] The technical scheme of the utility model: a special fixture for drilling and boring irregular parts, comprising a fixture body, a pressing plate and a set screw; the pressing plate is connected with the fixture body by the set screw; the fixture body is provided with a clamping position baffle, an L-shaped baffle and a stop block, the clamping position baffle is used for clamping and fixing the fixture body, and the L-shaped baffle, the stop block, the pressing plate and the set screw are used for clamping and fixing the processed parts.

[0006] Further, the connecting hole for the set screw on the pressing plate is a gourd-shaped hole.

[0007] Further, the number of set screws is at least 3.

[0008] Further, the L-shaped baffle is used for clamping and fixing the processed parts in horizontal two directions.

[0009] Further, the pressing plate combined with the screw is used for clamping and fixing the processed parts in vertical direction.

[0010] Compared with the prior art, the utility model discloses accurate positioning, and through reasonable design positioning surface, ensure the position accuracy of part in clamp, improve the machining accuracy. Clamping firmly, the utility model discloses can provide even, stable clamping force, prevent the displacement of part in the processing. BRIEF DESCRIPTION OF DRAWINGS

[0016] The utility model will be further explained in detail in connection with the drawings, but is not the limitation of the protection scope of the utility model.

[0017] The utility model embodiment and use mode:

[0018] An irregular part drilling, boring hole special fixture, including clamp body 1, pressing plate 2 and tightening screw 3, pressing plate 2 is connected with clamp body 1 through tightening screw 3, clamp body 1 is equipped with clamping stop plate 4, L-shaped stop plate 5 and stop block 6, clamping stop plate 4 is used for the clamping and fixed of clamp body 1, L-shaped stop plate, stop block 6, pressing plate 2 and tightening screw 3 are used for the clamping and fixed of machining part 7.

[0019] Further, the connecting hole for tightening screw 3 on pressing plate 2 is a gourd-shaped hole. It can be used to take down pressing plate 2 without completely removing the screw, which is convenient for loading and unloading machining part 7 during processing.

[0020] Further, the number of tightening screw 3 is at least 3.

[0021] Further, the L-shaped stop plate 5 is used for the clamping and fixed of machining part 7 in two horizontal directions.

[0022] Further, the pressing plate 2 is combined with the screw to be used for the clamping and fixed of machining part 7 in the vertical direction.

[0023] When the part 7 is processed, the specific operation method is as follows: first, the clamp body is placed on the processing machine tool, the clamp body is fixed by clamping the clamp stop plate 4 with the three-jaw chuck 8, the clamping screw 3 on the clamp body 1 is loosened, the pressing plate 2 is taken off through the gourd-shaped screw hole, the two end faces of the upper left corner of the part 7 to be processed are attached to the positioning surface of the L-shaped stop plate 5, the lower end face of the part 7 is positioned and fixed through the clamp body 1 and the stop block 6, and finally the pressing plate 2 is covered to compact the part, and the three clamping screws 3 are tightened.
