Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with examples.

[0017] The water-cooled mechanical moving device designed in the present invention is mainly composed of a reducer, a transmission screw, a square nut, a connecting seat, a water-cooled frame, a moving lifting rod and a connecting flange. Its structure is as follows: figure 1 shown. The transmission machine is composed of a servo motor 1 and a reducer 2, and the reducer 2 is connected with the seat plate 4 through screws 3; the connecting seat 5 has two connecting flanges, and the upper connecting flange and the seat plate 4 use bolts Connection, the connecting flange below is also connected with the upper flange 7 of the water-cooling frame by bolt connection. Two sets of thrust bearings 6 are used for axial fixing of the transmission screw 11 .

[0018] The water-cooled frame is the main body of the water-cooled mechanical mobile device. It is a steel structure, which is composed...

Abstract

A water-cooling mechanical moving device for a test piece in a high-vacuum single-crystal growth furnace relates to a mechanical device. The water-cooling mechanical moving device mainly comprises a speed reducer, a transmission lead screw, a square nut, a connecting base, a water-cooling machine frame, a moveable lifting and pulling rod, a connecting flange and the like. The water-cooling mechanical moving device is arranged on the high-vacuum single-crystal growth furnace through the connecting flange. The mechanical moving device is subjected to heat-sink cooling by a circulating water-cooling method. The lower end of an output piece of the set of water-cooling mechanical moving device penetrates into the high-vacuum single-crystal growth furnace, and a copper test piece which needs heat treatment is clamped at the lower end head of the moveable lifting and pulling rod. The moving speed of the moveable lifting and pulling rod in the water-cooling mechanical moving device is controlled according to requirements of a heat treatment process, and the copper test piece can be slowly and uniformly changed from a high-temperature solid-state phase to a low-temperature solid-state phase, so that metal single-crystal copper with low-temperature solid-state phase is obtained. The water-cooling mechanical moving device can effectively solve the problem about control on moving and heat treatment states of the test piece in the high-vacuum single-crystal growth furnace.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a water-cooled mechanical moving device for a test piece of a high-vacuum single crystal growth furnace. Background technique [0002] With the development of information technology, the transmission wires of wires and cables are constantly developing, their usage is increasing, and their performance requirements are getting higher and higher. Ordinary polycrystalline copper is difficult to meet this requirement. Single crystal copper is the preferred material for transmission wires due to its strong ability to eliminate lateral grain boundaries, good fidelity and plasticity. [0003] But at present, there is no special mechanical moving device for the specimen of high vacuum single crystal growth furnace. Contents of the invention [0004] The object of the present invention is to provide a water-cooled mechanical moving device for a high-vacuum single crystal growth furnace sample. The...
