Description

Technical Field

[0001] This utility model relates to the technical field of two-wire and one-hard machining centers, and in particular to an adaptive clamping device for two-wire and one-hard machining centers. Background Technology

[0002] In the field of modern machining, two-spindle, one-hardened machining centers (i.e., hardened rail machining centers with dual spindles and dual turrets) are widely used in industries such as automotive, aerospace, and mold manufacturing due to their high efficiency, high rigidity, and comprehensive machining capabilities. However, when machining complex parts, the workpiece clamping stability and self-adaptive clamping capability directly affect machining accuracy, surface quality, and production efficiency. Traditional clamping systems typically employ mechanical, hydraulic, or pneumatic clamping methods. However, when dealing with irregularly shaped workpieces, thin-walled parts, or multi-variety, small-batch production, workpieces with complex shapes or varying dimensions require frequent fixture changes or clamping position adjustments, reducing production efficiency. Therefore, we have redesigned a self-adaptive clamping device for two-spindle, one-hardened machining centers. Utility Model Content

[0010] Compared with related technologies, the adaptive clamping device for a two-wire, one-hard machining center provided by this utility model has the following advantages: This utility model provides an adaptive clamping device for a two-wire, one-hard machining center. A first driving threaded rod rotates within a first limiting sliding groove, adjusting the overall position of the first sliding base. Simultaneously, a second driving threaded rod moves the second sliding base within the second limiting sliding groove, controlling the distance between the auxiliary extrusion plates and the main extrusion plate. This allows for clamping and fixing of the metal parts to be processed. Multiple retractable base columns and telescopic contact columns are positioned on the surfaces of the main and auxiliary extrusion plates. When the telescopic contact columns are compressed by the metal parts, they automatically retract into the retractable base columns. The compression springs also retract, enabling the clamping and fixing of metal parts of different shapes, improving the device's adaptability. When the metal part is fixed between the main and auxiliary extrusion plates, rotating the adjusting motor rotates the power shaft, allowing for machining operations at different angles.
