Conical cone crusher device combination machine use and impr

Be processed in accordance with the pre-processing program, we found that the support roller axial movement of a large range before the backup roll, the impact of processing normal.

 

　　So that the support roller traverse reasons: four-jaw chuck clamping alignment accuracy, the tailstock bed concentricity error on the accuracy of the backup roll support shaft diameter cylindrical errors, broken cone support shaft of misalignment errors, we check for possible causes: re tailstock; re alignment of the workpiece, the circle is to ensure that within 0 10mm; and bed and tailstock lever pulled in order to avoid too large to lead to the end of the workpiece weight. seat back; to check the degree of support shaft diameter cylindrical support shaft diameter cylindrical degrees to meet the requirements; carefully to support the roll, the roll still ran of cone crusher Cone support shaft diameter concentricity error between rotating workpiece that is broken the pyramidal exist bent, according to broken cones usage: crushing the ore load, severe impact, load concentrated in the crushing cone is very likely to form the central bending, check points round is in the cone crusher cone central concentricity The error is 3 5mm.

 

　　To solve this problem must be eliminated workpiece positioning of the fork head while carrying a rotating processing.

 

　　Workpiece positioning: two support rollers is equivalent to a long V-shaped iron positioning the limit YYZZ four degrees of freedom, the tailstock limit X dial fork with for the clearance fit....
