Description

Technical Field

[0001] The utility model relates to the technical field of horizontal machining centers, in particular to a clamping and stabilizing device for horizontal machining centers. Background Art

[0002] A horizontal machining center is a machine tool with a horizontal table and the workpiece moving in the horizontal direction. This design has some advantages and features over a vertical machining center (with a vertical table): Since the workpiece moves in the horizontal direction, gravity helps to fix the stability of the workpiece during machining, reducing vibration and deformation, thereby improving machining accuracy. Since the workpiece is located on a horizontal table, the chips and coolant generated during machining can be more easily discharged from above the workpiece and will not accumulate on the workpiece surface or in the clamping device, keeping the machining area clean. Operators can more easily access and operate the workpiece because they are located on a horizontal table. In addition, maintenance personnel can more easily access various parts of the machine tool for maintenance and servicing. Horizontal machining centers usually have larger tables and machining areas, which are suitable for machining large workpieces or situations where a large range of machining is required. Since the workpiece is located on a horizontal table, it is easier to install fixtures and fixtures, realize multi-process machining, and improve machining efficiency and productivity. Horizontal machining centers are widely used in the automotive, aerospace, mold manufacturing, shipbuilding and other fields, providing efficient and reliable solutions for the precision machining of various workpieces.

[0003] In order to ensure machining accuracy and safety, the clamping stabilization device is crucial in the horizontal machining center. The existing clamping stabilization device for the horizontal machining center has a relatively simple clamping method, which makes the workpiece easy to shake during machining and has poor clamping stability. Therefore, we proposed a clamping stabilization device for the horizontal machining center to solve the above problems. Utility Model Content
