Carousel system for machining separate shoe last components

摘要

Equipment for machining the joint area of a shoe last comprising separate heel and front components comprises a rotating table (2) with four clamping stations (3), two for heel components, two for the front components and four machining stations on a fixed part (1) around the rotating table (2). The first station has a stop (4), the second two drills (5), the third a chain miller (6) and the fourth two milling cutters. Drills (5) are in two groups at defined distances perpendicular to the rotating table (2) and both milling cutters (7) are on a common axis perpendicular to the table (2). Both milling cutters (7) and drills (5) are guided in auxiliary frames (8) moving tangentially (T-T) to the rotary table (2). Tool positioning in the direction perpendicular to the table is effected by bearings between the auxiliary frames (8) and the fixed part (1). Movement of the auxiliary frames (8) is by pneumatic or hydraulic cylinders. The third working station performs two linear and one rotational feeding movement. The linear movements are perpendicular to each other, radial to (R-R) and perpendicular to the table (2). The rotation axis (R) of the rotary feeding movement is perpendicular to the plane formed by the radical (R-R) and perpendicular directions and passes through the midpoint of the front chain diverter of the chain miller (6) when the latter has reached the max. feeding position.
