Description

Technical Field

[0001] This utility model relates to the field of vertical machining center technology, and more specifically, to a positioning mechanism for a vertical machining center. Background Technology

[0002] A vertical machining center is a machining center whose spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and small shells. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting operations. Before machining, the workpiece needs to be positioned.

[0003] A search revealed that utility model patent CN219704195U discloses a positioning mechanism for a vertical machining center, including a machining table, a fixed base, an adjusting component, a shaped clamp, a positioning component, and a quick-release component. The fixed base is fitted onto the machining table, and the adjusting component is slidably inserted into the fixed base. One end of the adjusting component is fixedly connected to the shaped clamp, which slides against the fixed base. This utility model's positioning mechanism for a vertical machining center, when fixing a workpiece during machining, places the workpiece inside the fixed base and then pushes the adjusting components around the fixed base, causing the shaped clamp to firmly hold the workpiece. The positioning component design secures the adjusted position after pushing the adjusting component, preventing springback. The quick-release component design allows the fixed base to be easily removed from the machining table, facilitating the use of fixed bases for different applications.

[0004] However, the aforementioned patents still have the following shortcomings: When the fixed base is installed on the machining table, connection holes for quick-release parts need to be set on the worktable. Due to the different dimensions of the fixed base, the installation positions of the quick-release parts vary, resulting in the need to open multiple connection holes at different positions on the worktable, which is not very practical; furthermore, the four transmission rods and four irregularly shaped clamps are driven by the first spring, which makes it inconvenient to push the workpiece to a suitable position on the machining table when the workpiece is heavy. To address these issues, we propose a positioning mechanism for a vertical machining center. Utility Model Content
