High-precision numerical control machining center

Abstract

The high-precision numerical control machining center comprises a main body, a moving assembly and a clamping assembly, the moving assembly is arranged in the main body, the clamping assembly is arranged on the moving assembly, the clamping assembly comprises two clamping units, each clamping unit comprises a clamping block and a suction cup, and the moving assembly comprises a power unit and a moving unit. According to the high-precision numerical control machining center, precise movement of the tool bit is achieved through the first lead screw and the air cylinder, the machining precision is improved, the clamping assembly is driven to operate through the moving assembly, auxiliary clamping is conducted on a workpiece, the two ends of the workpiece are clamped through the chuck and the clamping assembly, and the situation that the machining part of the workpiece is emptied due to the fact that the workpiece is long is avoided; the clamping stability is improved, a workpiece is clamped in a surrounding mode through the clamping blocks, the contact area with the workpiece is increased, the outer wall of the workpiece is adsorbed through the suction cups, the workpiece is prevented from rotating during machining, the better clamping and fixing effect on the workpiece is achieved, and the machining precision is improved.

Description

technical field [0001] The invention relates to a high-precision numerical control machining center. Background technique [0002] The CNC machining center is a high-efficiency automatic machine tool suitable for processing complex parts composed of mechanical equipment and a CNC system. After the workpiece is clamped once, it can complete more processing content and has high processing accuracy. It combines milling, boring, drilling Functions such as tapping, thread cutting and thread cutting are concentrated on one device, so that it has multiple technological means. [0003] Existing CNC machining centers generally use a chuck to clamp one end of the workpiece. When the length of the workpiece is long, the middle part and the processing part of the workpiece are in an empty state, which affects the stability of the clamping and produces a large Vibration will cause the workpiece to shake, or even cause the workpiece to fall off, which will affect the processing accuracy....

Problems solved by technology

[0003] Existing CNC machining centers generally use a chuck to clamp one end of the workpiece. When the length of the workpiece is long, the middle part and the processing part of the workpiece are in an empty state, which affects the stability of the clamping and produces a large Vibration will cause the workpiece to shake, or even cause the workpiece to fall off, which will affect the processing accuracy. At the same time, the existing auxiliary clamping mechanism generally sets clamping blocks on both sides of the workpiece, and then drives the two clamping blocks to move through two cylinders. , to realize the auxiliary clamping of the workpiece, using two cylinders as the driving source, the energy consumption is large, and it takes up a large space, and the existing clamping mechanism is generally clamped by a simple clamping block, and the workpiece is rotated during processing. , the workpiece may rotate with the cutter head, resulting in a small rotation of the workpiece, which affects the machining accuracy
