Abstract
A rim drilling and milling machine has a base (10), a column (20), a turret (30), a saddle (40), a table (50), and a fixture unit (60). The fixture unit (60) has a foundation (61) and four clamping seats defined as two first clamping seats (63A) and two second clamping seats (63B). The first clamping seats (63A) are slidably mounted on the foundation (61) along a first radial direction, and are disposed at positions diametrically opposite in the first radial direction. The second clamping seats (63B) are slidably mounted on the foundation (61) along a second radial direction perpendicular to the first radial direction, and are disposed at positions diametrically opposite in the second radial direction. The four clamping seats can clamp at four equiangular points of a wheel rim.
Claims15
A rim drilling and milling machine comprising:
- a base;
- a column fixed on the base, protruding upward from a top of the base, and having a vertical rail unit;
- a turret vertically slidably connected with the vertical rail unit;
- a saddle horizontally and linearly slidably connected with the base and having a sliding direction;
- a table horizontally and linearly slidably connected with the saddle and having a sliding direction perpendicular to the sliding direction of the saddle;
- and
- a fixture unit fixed on a top of the table and having:
- a foundation mounted on the table and having:
- a first radial direction;
- and
- a second radial direction perpendicular to the first radial direction;
- and
- the fixture unit also having four clamping seats defined as two first clamping seats and two second clamping seats, wherein
- the first clamping seats are slidably mounted on the foundation for sliding in the first radial direction and are respectively disposed at positions diametrically opposite in the first radial direction of the foundation;
- and
- the second clamping seats are slidably mounted on the foundation for sliding in the second radial direction and are respectively disposed at positions diametrically opposite in the second radial direction of the foundation;
- and
- wherein the fixture unit further has a linkage unit having:
- a linkage seat rotatably mounted on the foundation;
- and
- four linking rods connected with the linkage seat, each of the linking rods connected to a respective one of the clamping seats;
- wherein the fixture unit further has a linear driving unit being adjustable in a longitudinal length of the linear driving unit in the first radial direction and having two ends each connected to a respective one of the first clamping seats.
