Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a multi-functional fixture device for machining centers. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, achieving multiple machining functions. In machining centers, workpieces are generally clamped using fixtures to fix their position and prevent them from shifting during subsequent machining processes, which would affect the quality of the machining work.

[0003] In actual use, the multi-functional fixtures used in existing machining centers require different clamping tools for workpieces of different sizes, thicknesses, or shapes. This requires operators to select the appropriate fixtures according to the specifications of the workpieces before they can carry out the machining work, which affects the overall work efficiency. In addition, when double-sided machining is involved, the machine needs to be stopped for adjustment, which makes it inconvenient to flip the workpieces and reduce downtime. Utility Model Content

In addition, when double-sided processing is involved, it is necessary to stop the machine for adjustment, which is not convenient for flipping the workpiece to reduce downtime.

[0014] (III) Beneficial Effects

[0016] 1. This machining center uses a multi-functional clamping device. Through the adjustment of components, moving blocks, clamping block A, and adjusting components and clamping block B, the workpiece is placed between clamping block A and clamping block B during use. According to the length of the workpiece, the servo motor is activated, and the forward and reverse threaded rods drive the two moving blocks to move and clamp the workpiece. According to the thickness of the workpiece, the hydraulic rod is activated, and the extension and retraction of the hydraulic rod drives the clamping block B to adjust the clamping width.

This achieves the effect of flipping the workpiece, avoiding the need to stop the machine to flip and adjust the workpiece during double-sided machining, which would have resulted in wasted time and costs. It helps to reduce downtime and shorten the machining cycle. Attached Figure Description
