A coating fixture for physical vapor deposition

Abstract

The invention discloses a film-coating clamp for physical vapour-phase deposition. The film-coating clamp comprises a base, a base plate bearing a workpiece and a rib plate which is arranged between the base and the base plate for connecting the base to the base plate, wherein the upper surface of the base is crossed, and clamping devices are fixedly connected above four end parts of the base plate separately; each clamping device consists of a supporting base, a propelling bolt and a contact head; a plurality of pairs of regular threaded holes I are formed in the base plate; each supporting base passes through the threaded holes I and is fixedly connected with the base plate through a fixed bolt, each propelling bolt is in threaded connection to the inner side of the supporting base through a threaded hole II formed in the supporting base, the contact head is fixedly connected to the end part of the propelling bolt; and a plurality of pairs of upper access holes are further formed inthe base plate, and the upper access holes are connected with other film-coating clamps for physical vapour-phase deposition through supporting rods. The film-coating clamp is simple and firm in structure, is conveniently manufactured, is convenient in operation, is high in coating efficiency, is strong in universality, can meet different workpiece coating needs, greatly reduces the number of workpiece coating clamps, reduces coating cost, is economical and reliable, is wide in application prospect, and is beneficial for popularization and application.

Description

technical field [0001] The invention relates to the technical field of workpiece fixtures, in particular to a coating fixture for physical vapor deposition. Background technique [0002] With the continuous development of physical vapor deposition hard wear-resistant coating technology, the application of coatings is also becoming wider and wider. In order to adapt to and meet customers' constant pursuit of product quality, the modern machinery manufacturing industry puts forward higher requirements for forming tools, especially for forming molds, such as injection molds. In order to meet the processing needs, on the one hand, the performance of existing materials is constantly being explored, and on the other hand, better alternatives are constantly being searched for. Physical vapor deposition technology is an emerging technology that continues to develop under such circumstances. After the workpiece is coated, it can not only maintain good precision, but also improve th...

Problems solved by technology

This results in defects such as poor flexibility of the fixture and single function, which increases the manufacturing cost of the enterprise and prolongs the production cycle of the enterprise.

Since the production of the enterprise requires workpieces of different specifications, there is a demand for a large number of special coating fixtures, which brings inconvenience to the entire coating process and does not conform to the three principles of quality, efficiency and economy of the enterprise.
