This invention discloses a
swashplate-based lapping device for lapping a
swashplate and a
swashplate base. The bottom surface of the swashplate has a first arc-shaped curved surface, and the top surface of the swashplate base has a second arc-shaped curved surface that mates with the first arc-shaped curved surface. The device includes: a drive component for driving the swashplate to reciprocate on the swashplate base; a support
assembly for supporting the drive component; and a base
assembly for fixing the swashplate base. This invention ensures
close contact between the swashplate and the swashplate base, resulting in more uniform pressure contact on the arc surface. It solves the problem of uneven force distribution and difficulty in ensuring contour accuracy caused by manual operation, greatly improving
machining accuracy and efficiency. Furthermore, this structure converts rotary motion into reciprocating
linear motion, making operation more convenient.
