Abstract

The utility model relates to a device for driving plated element to be slowly rotated, which is characterized in that the device for driving plated element to be slowly rotated comprises a bracket, a speed reducing motor is arranged on the bracket, a plurality of pairs of eccentric discs whose phase difference is 180 DEG are arranged on a motor shaft, a hook is respectively hung in each of the eccentric disc grooves of each pair of eccentric discs, the other end of the hooks are respectively hung on holes on the two diagonals of plated elements, and the centre distance a of two eccentric discs is bigger than the centre distance b1-15 mm of two diagonal holes of the elements. The device has compact structure. With the use of the device, the electroplating efficiency and the plating layer quality can be improved, the semi-automation can be realized, and the labor intensity is reduced.

Description

Drive and plated part swivel arrangement at a slow speed

The utility model relates to a kind of driving and is plated part swivel arrangement at a slow speed, particularly a kind of device that is rotated at a slow speed in plating bath by the plating part that drives more than the plating liquid level.

Run into plating ring flange class, tube kind part through regular meeting in electroplating industry, particularly have the part of radial blind holes, if these parts are still used fixedly suspending way plating, it is inhomogeneous each position thickness of coating then to occur; The downward interior gas of blind hole of mouth can't be discharged, do not plate, though other remedial measures commonly used now, for example: change frequently and hang hole upset part, or swing part manually, but exist shortcomings such as electroplating efficiency is lower, labour intensity is bigger, therefore, be necessary to provide a kind of the driving by the swivel arrangement of plating part.

The purpose of this utility model provides a kind of device that is rotated at a slow speed by the plating part that drives in plating bath more than the plating liquid level, this apparatus structure compactness uses this device can improve electroplating efficiency and quality of coating, realizes semi-automation, reduces labour intensity.

For achieving the above object, the utility model is taked following design: this driving plated part at a slow speed swivel arrangement comprise: on support, the support reducing motor is housed, many eccentric disks to phase differential 180 degree are installed on the motor shaft, hang a hook respectively in each eccentric disk hook groove of every pair of eccentric disk, the other end of hook is hung in by plating being positioned on two cornerwise holes of part, and two eccentric disk width between centers a are greater than part two diagonal bore width between centers b1-15mm.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation

Fig. 2 is an a pair of eccentric disk and the connection diagram of being plated part among Fig. 1

Fig. 3 is the eccentric disk part sectioned view

In Fig. 1, Fig. 2, Fig. 3,1 compares reducing motor for big reduction of speed, twin-stage cycloid reduction box motor for example, be equipped with many

eccentric disks

3,5 on the motor shaft 2, be equivalent to a bent axle, hang a

hook

4,6 in each eccentric disk groove 14 of every pair of eccentric disk respectively phase differential 180 degree, the other end of two hooks is hung in being positioned on two cornerwise holes 7,8 by plating

part

11,9,10 is blind hole among the figure, and 12 is plating tank, and 13 electroplate liquids hook can adopt the copper hook.The rotation at a slow speed of the motor shaft by eccentric disk is housed because hook slides, drives workpiece rotation synchronously in plating bath on eccentric disk.Because hook length precision can not be very high, also because hook has recoverable deformation, in order to overturn smoothly at two dead points that guarantee part, two eccentric disk width between centers a must be greater than the about 1-15mm of part two diagonal bore width between centers b, and its concrete numerical value is by being decided by size, the weight of plating part.

Above-mentioned eccentric disk quantity depends on the needs, and through test, adopts 40 eccentric disks, hangs 20 ring flanges (each about 1kg), and the about 5mm of a＞b, a spool rotating speed are 2 rev/mins, and electroplating time was reduced to 45 minutes by 1 hour 40 minutes, and also topped coating bottom the blind hole.

The utility model has the advantages that: this apparatus structure compactness, adopt this device to improve electroplating efficiency and electricity Coated coating quality, uniformity have particularly improved the speed of electroplating in the blind hole, and in addition, this device is convenient to reality Existing semi-automatic, reduce labour intensity.

Claims

1, part swivel arrangement is at a slow speed plated in a kind of driving, it is characterized in that: it comprises: on support, the support reducing motor is housed, many eccentric disks to phase differential 180 degree are installed on the motor shaft, hang a hook respectively in each eccentric disk groove of every pair of eccentric disk, the other end of hook is hung in by plating being positioned on two cornerwise holes of part, and two eccentric disk width between centers a are greater than part two diagonal bore width between centers b1-15mm.
