Embodiment: A kind of drilling equipment for cardan shaft shell with chip removal device, see Fig. 1 and Fig. 2, comprise drilling machine 1 and workbench 11 fixed on the driller 1, workbench 11 is groove type, its A base 2 is fixed inside, and the base 2 is in the shape of a U-shaped groove. The top of the base 2 is connected to an upper mold 21; the base 2 below the upper mold 21 is slidingly connected to a lower mold 22, and one side of the lower mold 22 is connected to a Cylinder 222, lower mold 22 is connected with the side of cylinder 222 and is horizontally provided with cross-section and is the traverse groove 221 of convex font shape, between upper mold 21 and lower mold 22 clamps cardan shaft shell 4; On lower mold 22 relative to The position of the workbench 11 facing the other side of the side connected with the cylinder 222 is connected with a connecting pipe 31, one end of the connecting pipe 31 is connected with an air pump 3, the other end is connected with a four-way 32, and the other three parts of the four-way 32 Both ends are connected with the nozzle 33 facing the cardan shaft housing 4. After the cardan shaft housing 4 is processed, it can be sprayed with high-pressure gas through the nozzle 33 to blow away the waste debris adhering to it, improving the surface cleanliness.

Referring to Fig. 2 and Fig. 3, the traversing groove 221 runs through the lower die 22, and the telescopic rod of the cylinder 222 is fixed with a connection block 223 that cooperates with the traversing groove 221, and the connecting block 223 can be inserted into the traversing groove 221 and It can only slide relative to the traverse groove 221 along the length direction of the telescopic rod perpendicular to the cylinder 222; a lifting groove 224 is provided at the geometric center of the bottom surface of the lower die 22, and a hydraulic cylinder 225 is connected below the base 2, and the lifting groove 225 is connected to the bottom of the base 2. 224 is provided with a through hole 23 at the matching position, and the telescopic rod of the hydraulic cylinder 225 can be abutted in the lifting groove 224 through the through hole 23. When the cardan shaft housing 4 needs to be clamped and drilled, the hydraulic cylinder 225 is controlled to Its telescopic rod stretches out, because there is no mutual vertical limit between the traversing groove 221 and the connecting block 223, so the lower mold 22 can normally clamp the cardan shaft housing 4 with the upper mold 21; When cleaning the cardan shaft housing 4, lower the lower mold 22 and make the telescopic rod of the hydraulic cylinder 225 leave the lifting groove 224. At this time, the connecting block 223 is inserted in the traverse groove 221, and the cylinder 222 is controlled so that the telescopic rod pushes the lower mold 22 drives the cardan shaft casing 4 to move toward the nozzle 33, opens the nozzle 33 to spray air on the cardan shaft casing 4, removes the cardan shaft casing 4 after cleaning and pulls the lower mold 22 back to its original position through the cylinder 222, and lowers the mold 22 during the whole process.
