A clamping fixture for tiny hardware parts used in CNC machining center

Abstract

The invention discloses a small hardware clamping die for a numerical control machining center. The small hardware clamping die comprises a worktable, a fixed frame and an auxiliary clamping structure. A supporting spring is connected to the bottom end surface of the fixed frame in an integrated forming manner, and a supporting plate is connected to the other end of the supporting spring in an integrated forming manner. Round slots are symmetrically formed in the fixed frame, thread slots are formed in one ends of the round slots, cylinders are inserted into the round slots, and thread columnsare in threaded connection in the thread slots. It is quite simple and convenient to clamp and fix a processed workpiece by means of the fixed frame, the supporting spring, the supporting plate and an arc-shaped elastic clamping plate and bruise of a workpiece in a clamping process can be avoided, so that the processing quality of the workpiece is guaranteed. The clamping and fastening degree ofthe processed workpiece can be improved effectively by means of the arranged auxiliary clamping structure, so that the workpiece is not loosened in the processing course, and therefore, normal work isguaranteed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hardware processing equipment, in particular to a small hardware clamping fixture for a numerical control machining center. Background technique [0002] Hardware: traditional hardware products, also known as "small hardware"; refers to five metals: gold, silver, copper, iron, and tin; through manual processing, it can be made into works of art or metal devices such as knives and swords; hardware in modern society is more extensive , such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies, etc.; hardware products are mostly not final consumer goods, and CNC machining center equipment is usually used for hardware processing. CNC machining center (numerically controlled production center) is a It is a CNC machine tool with complete functions; it is one of the CNC machine tools with the highest output and the most widely used in the world; the CNC machining center ...

Problems solved by technology

[0003] For the processing of hardware workpieces in CNC machining centers, fixtures are needed to clamp and fix the workpieces to ensure the smooth progress of the processing work. The existing fixtures for workpieces are more troublesome for clamping, fixing and disassembling of workpieces on the one hand. , which brings inconvenience to the staff. On the other hand, without good stability and protection, the workpiece may become loose during the work process, and may cause scratches to the surface of the workpiece, thereby reducing product quality. For this reason, The present invention proposes a tiny hardware clamping fixture for numerical control machining centers to solve the above problems
