Six characteristics of three coordinate fixture

The three coordinate fixture not only improves the product quality, but also reduces the labor of workers. It plays a very important role in automation, mechanization and other aspects. The three coordinate fixture is a kind of machine that can accurately locate the weldment, facilitate the detection and ensure the accuracy. It has the following characteristics.

Cmm fixture clamps characteristics

(1) The positioning accuracy of parts is required to be higher, and the relative position accuracy of welds is higher, which should be ≤ 1mm.

(2) Since weldments are generally composed of several simple parts by assembly and welding, and the assembly and tack welding of these parts are carried out in sequence on the welding fixture, their positioning and clamping are carried out separately one by one.

(3) The positioning of the three coordinate fixture before and after the process must be consistent.

(4) As the displacement angle of the positioner is large, the use of movable manual pin shall be avoided as far as possible for the three coordinate fixture.

(5) Three coordinate fixture shall be compressed by cylinder as far as possible, and cylinder with magnetic switch shall be configured. So as to transmit the pressing signal to the robot.

(6) Different from the common welding fixture, the three coordinate fixture can weld the workpiece on the reverse side as well as on the front side.

The above six points are the main differences between the three coordinate fixture and the ordinary fixture. When designing the three coordinate fixture, these differences should also be taken into account to better design the machinery that meets the use requirements.
