Description

Fixture for glass mold engraving and milling matching with machining center

Technical field

The invention belongs to the technical field of tooling fixtures, and particularly relates to a fixture for glass mold engraving and milling matched with a machining center.

Background technique

The aforementioned machining center is an automated processing equipment that has been developed and applied in recent years. It is found in the Chinese patent literature published so far, such as CN104002200A (Vertical Composite Multi-axis CNC Machining Center), CN104476215A (a kind of flap horizontal Machining Center), CN104802013B (a multi-face machining CNC machining center), CN105364491B (a five-axis CNC machining center), CN106426590A (CNC glass machining center) and CN206952549U (a CNC machining center), and so on. The aforementioned glass mold engraving and milling can be known from the literal interpretation: the glass mold can be carved and the glass mold can be milled in the machining center. For the glass mold carving and / or milling, the glass mold needs to be in a clamped state of reliable clamping, and the clamping of the glass mold needs to be realized by the fixture.

As the industry knows, tooling fixtures play an important role in the production of industrial products, and the processing of glass molds is no exception. The so-called fixtures refer to special equipment or tools used to clamp or position the workpiece during machining to meet certain process requirements. It is usually required to meet the requirements of no interference during production, accurate and reliable positioning, and convenient operation. Since fixtures have the exclusive characteristics for manufacturing certain products, the degree of generalization is low, and they are often produced by manufacturers who produce corresponding products in a tailor-made manner. Most of the glass mold manufacturers are equipped with various fixtures in a self-made manner. In recent years, although various medium and high-grade machining centers have been applied to small and medium-sized enterprises, the processing products processed by the machining center have the advantages of high speed, good quality and high degree of product standardization. However, if there are no tooling fixtures matching the machining center, then these The advantages are not reflected. The glass mold as a workpiece is put into the processing center to carry out such as engraving, engraving, drilling and lifting holes, opening positioning grooves, opening wear plate grooves, processing vest eyes (hanging nail holes), milling triangles, milling arcs and tapping In the process of hole threading, the glass mold must be reliably clamped or locked by the fixture, and the fast clamping or un-clamping of the workpiece by the fixture is critical to ensure the processing efficiency and processing quality of the machining center. the elements of.

In the published Chinese patent literature, there is no shortage of technical information about fixtures for glass mold processing, such as "tooling fixtures for processing glass molds" recommended by CN101659015B and "rotary fixtures for glass mold processing" provided by CN102689187A. These two patents each have the technical effects described in the technical effects column of the specification, but the following shortcomings exist: First, since both patents are for the horizontal clamping of the glass mold (the horizontal clamping means glass) The mold cavity of the mold is proposed downward, that is, it is not proposed for the cavity machining of the glass mold, so that it is not necessary to rotate the glass mold in the clamped state at any angle of 360 degrees in the circumferential direction as needed. For the engraving of the mold cavity of the glass mold, there is no doubt that the cavity should be oriented upwards and the glass mold should be rotated at any angle of 360 degrees in the circumferential direction. Therefore, neither of the above two patents can give the glass mold a circumferential direction. The revelation of rotation, therefore, does not have any enlightenment to the glass mold clamping in the carving process; second, due to the need to pass the clamp At the same time, the opening and closing mechanism drives the two pairs of clamping arms to move toward each other or disengage from each other, so the overall structure is complicated, which is not conducive to manufacturing and assembly, and is not convenient for daily use and inspection, especially due to many movement transmission links, affecting the clamping to some extent. The reliability of the installation.
