Rotating stand for vertical type aluminium plating machine

Abstract

The invention relates to a rotating stand for a vertical type aluminium plating machine, which is arranged around an aluminium plating electrode stand of the vacuum aluminium plating machine and comprises an upper rotating disk (5), a lower rotating disk (6), a rotating stand shaft (7) and a transmission gear component (G) of the rotating disk. An upper fixing board (17) is arranged on the top endof the rotating stand shaft, a lower fixing board (27) is arranged on the lower end of the rotating stand shaft, a through hole (6a) which is pressed in a bearing holder from the upper side of the upper rotating disk is arranged on the upper rotating disk, the bearing holder is provided with a shaft hole (5b) of a connecting rod, the inner cavity of the bearing holder is provided with a ball bearing (10) which supports one end of the connecting rod, the other end of the connecting rod is provided with a conical bearing (11), and an unloading opening (12) is formed between the conical bearingand the lower surface of the upper rotating disk. A hook hitch hole (17a) which is wider than the unloading opening and an opening groove (17b) which is communicated with the hook hitch hole and is wider than the diameter of the connecting rod are arranged on the upper fixing board. According to the invention, the operation of the installation of the rotating stand shaft is convenient, the rotation is stabile, the uniformity of the rotate speed of the rotating disks and the percent of pass of aluminium plating work pieces are increased, and the service life is prolonged.

Description

Turn frame for vertical aluminizing machine Technical field The present invention relates to a vacuum aluminum plating equipment, in particular, the present invention relates to a rotary frame for a vertical aluminum plating machine used for vacuum aluminum plating technology. Background technique With the development of modern technology, vacuum aluminum plating technology has been more and more widely used. However, in the fields of automobile manufacturing and optical coatings, especially more and more automobile parts, whether made of metal or plastic, in order to obtain the required finish, brightness, surface reflection performance, etc., they need to be under a certain vacuum. Through energized evaporation and deposition, the workpiece is evenly covered with a thin aluminum film. However, the reflectors and decorative rings of automotive lamps are made of lightweight and durable plastics. In order to form high reflection performance, it is necessary to energize and eva...

AI Technical Summary

Problems solved by technology

It was relatively stable at the beginning of use and no problems were found, but after a month, it was found that the upper bearing of the turntable was exposed to the vacuum chamber, and after a period of use, it became unstable and not smooth

In the end, the bearing seized and did not turn, causing the bottom of the turntable bearing to

The second type completely follows the rotation structure of the horizontal aluminum coating machine, without any modification, it is used in the vertical aluminum coating machine, so it does not conform to and is not suitable for the rotation principle of the vertical turntable turret

(1) The operation is inconvenient, if the turntable is heavy, sometimes one person cannot install it;

(2) The rotation of the turret is unstable, because the weight of all turrets including the workpiece is directly driven by the gear in the lower part;

(3) Uneven aluminum plating, due to uneven rotational speed, the turntable shakes, which affects the workpiece by the plating surface, resulting in a decline in the pass rate;

(5) The gear wears seriously, and the service life of the rotating structure is shortened

Since the upper bearing of the upper turntable 5 is exposed in the vacuum chamber of the aluminum coating machine, there are the following problems: after a period of use, it will become unstable and not smooth, which will directly affect the quality and output of the aluminum-coated workpiece, and then cause the rotation of the turntable bearing. Seat wear, bearings seized and not rotated, etc., affect the service life of the rotating system of the aluminum plating machine

The structure of the turret 8 for this aluminum plating machine also has the following disadvantages: because the turret shaft has a certain weight, after a person inserts the turret shaft in the upper turntable ball bearing, he must hold the turret shaft while holding the turret shaft. The bottom joint of the turret shaft is fitted on the embedded shaft on the lower turntable, so the operation is inconvenient; since all the turret shafts including the weight of the workpiece are directly supported by the lower turntable, and there is a turntable transmission gear member under the lower turntable, so the rotation The rotation of the frame shaft will cause instability; due to the instability of the turret shaft, it will cause uneven speed and shaking of the turntable, resulting in uneven aluminum plating, resulting in a decline in the pass rate; due to the angle and direction of the turret shaft installation Limited, the effective aluminum plating area of ​​the vacuum chamber is reduced; since all the weight is directly supported by the lower turntable, the wear of the drive gear components of the turntable is serious, and the service life of the transmission structure is shortened
