Technical Field

[0001] This utility model relates to the technical field of pallet positioning and clamping equipment for five-axis machining centers, and in particular to a pallet positioning and clamping device for five-axis machining centers. Background Technology

[0002] The pallet positioning and clamping device for five-axis machining centers is mainly used to achieve precise positioning and reliable clamping of the pallet in the machining center. It is usually composed of a reference base, an adjusting base, a positioning mechanism, and a clamping mechanism. During the machining process, this device can ensure that the pallet is positioned quickly and accurately and maintains a stable clamping state during machining, thereby ensuring the accuracy and stability of the machining.

[0003] Existing five-axis machining centers rely on mechanical structures for positioning using pallet positioning and clamping devices. After long-term use, these devices are prone to wear and tear, leading to positioning deviations. In addition, manual adjustment of coordinates or replacement of fixtures is required. Problems such as damage to the pallet guide slider or loosening of the limit switch can directly affect the positioning stability, causing workpiece displacement or impact failures.

[0004] Existing pallet positioning and clamping devices for five-axis machining centers rely on mechanical structures for positioning. These devices are prone to wear and tear after prolonged use, leading to positioning deviations. Furthermore, manual adjustment of coordinates or replacement of fixtures is required.
