[0032] The jig 4 includes a jig main board 41 and jig modules 42. The jig modules 42 are evenly distributed in a square array above the jig main board 41. The jig modules 42 are semi-conical. The narrow ends of the jig modules 42 are away from each other. A transverse avoidance groove 411 is provided at the end of each jig module 42 on the jig main board 41. The jig 4 is arranged on the sliding table 31.

[0033] The pressing device 5 is arranged on the frame 1 above the cutting tool 2, and the pressing device 5 includes a mounting frame 51, a driving cylinder 52, a push plate 53, and a hydraulic rod 54. The driving cylinder 52 is vertically arranged in the mounting frame 51, and the output end of the driving cylinder 52 extends downward from the mounting frame 51. The push plate 53 is connected to the output end of the driving cylinder 52, and the hydraulic rod 54 is vertically arranged below the push plate 53.

[0034] Specifically, the cutting tools 2 on both sides are first in an open state, and the sliding table 31 is first at the end of the feed runway 3 away from the cutting tool 2. When in use, the aviation connector housing casting is placed on the fixture mainboard 41, and the aviation connector housing component corresponds to the fixture module 42. The shape of the fixture module 42 matches the shape of the inner wall of the aviation connector housing, so that the aviation connector housing can be stably placed on the fixture module 42, and the degree of thermal deformation of the casting can be judged according to the stability of the placement; the drive motor 24 works, rotates the ball screw 33 and drives the sliding table 31 to move toward the cutting tool 2 until the fixture 4 carries the aviation connector housing casting.

[0038] Embodiment three:

[0039] The difference between the third embodiment and the first embodiment is that an adjustable indexing table 24 is connected below the movable base 21 .

[0040] Specifically, when processing different batches of aviation connector housing castings, the distortion of the aviation connector housing castings is detected by measuring fixtures, and then the height of the adjusting dividing table 24 is adjusted. The raising or lowering of the adjusting dividing table 24 will drive the cutting tool 2 to tilt, thereby adapting to the distortion of the current processing batch of castings and improving the processing accuracy.

[0044] Embodiment five:

[0045] The difference between the fifth embodiment and the first embodiment is that a positioning hole 412 is provided in the middle of the outer side of the fixture module 42 on the fixture main board 41 .

[0046] Specifically, the positioning hole 412 can be used to avoid the connection protrusion on the side of the aviation connector housing, so that the aviation connector housing casting can be placed more stably on the fixture main board 41.

[0047] Embodiment six:

[0048] The difference between the sixth embodiment and the first embodiment is that ventilation grooves 421 are provided on the surfaces of both ends of the fixture module 42 along the circumferential direction.

[0049] Specifically, the vent groove 421 allows air to exist between the inner wall of the aviation connector shell and the fixture module 42, preventing the air between the aviation connector shell and the fixture module 42 from being exhausted, thereby making the aviation connector shell adsorbed on the fixture module 42 and difficult to remove.

[0050] Embodiment seven:

[0051] The difference between the seventh embodiment and the first embodiment is that an anti-slip end 55 is provided on the output end of the hydraulic rod 54 .

[0052] Specifically, the anti-slip end 55 can prevent the hydraulic rod 54 from sliding relative to the surface of the casting when fixing the casting, prevent the casting from slipping out from between the hydraulic rod 54 and the fixture module 42, and avoid leaving scratches on the surface of the casting when the casting is pressed.
