The outer side wall of the convex part 104 is closely attached to or close to the inner side wall of the corresponding front through groove 171. The inner side wall of the through groove formed in the middle of the sealing piece is elastically pressed against the outer side wall of the convex part 104. Thus, when the cutting fluid is sprayed onto the convex part 104 and the gate part 103, it will not splash into the box body 10, ensuring the processing quality.

[0039] Then, through the pushing of the push rod of the push-pull oil cylinder 1, the pressing block 12 is pressed against the middle of the rear wall surface of the corresponding front wall plate 102 of the steering knuckle workpiece 100 to fix the steering knuckle workpiece 100. At the same time, the positioning block 121 is inserted into the positioning through hole formed in the middle of the front wall plate 102 of the corresponding steering knuckle workpiece 100 to be processed. The rear part of the positioning block 121 is a cylindrical part, and the front part is a conical part. The outer side wall of its front part is closely attached to or close to the inner side wall of the corresponding positioning through hole, so as to position the steering knuckle workpiece 100.

[0040] Then, the protruding gate part 103 can be sawed by the cutting device. During cutting, the cutting fluid sprayed will basically not splash onto the steering knuckle workpiece 100 in the box body 10, ensuring the processing quality, so that there will be no spots formed by oil stains on the surface of the steering knuckle workpiece 100, ensuring the processing effect.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
