Description

I

The invention relates to electroplating, in particular to devices for electroplating small parts.

Closest to the present invention, there is a device for processing small parts in drums and bells, comprising a frame, a hollow body, equipped with a sealing, diverting lid, inside of which is a multi-faceted perforated drum fixed on the shaft, an electrolyte supply and discharge system D.

However, during loading and unloading, the housing takes different positions (tilts), and in the loading position, the retracted cover prevents the feed of parts into the drum. This complicates the design of the device (long-distance tipping mechanism), and increases the time of loading and unloading operations.

In addition, the known device can not be used as a suspension on electroplating auto-operating or mechanized lines.

The purpose of the invention is to increase productivity by simplifying the operation of unloading parts.

The goal is achieved by the fact that the device containing a frame, bell baths mounted on a hollow axis and a drive rotation of the bell baths is equipped with a fitting for supplying compressed air to the hollow axis, a spring-loaded stem located in the hollow axis, on the end of which the bottom of the bell bath is fixed, and a vibrator.

The vibrator is made in the form of a high-speed shaft with a cam mounted with the possibility of interaction with the hollow axis of the bell-shaped veins.

Claims (3)

In order to seal the hollow axis of the bell bath, the bottom of the bell bath is provided with a conical protrusion, and a conical socket is made in the adjacent end of the hollow axis. 3 9 FIG. 1 given the proposed device, the overall appearance; in fig. 2 shows section A-A in FIG. 1, in FIG. 3 shows the node I in FIG. 1. On the frame 1 (Fig. 1) there are racks 2 with a fixed axis 3 and low-speed k and high-speed drive shafts 5. On the axis 3 the holders of the bell bath 6 are suspended, holders 6 on the sleeves 7 are movable-planted hollow axles 8 s bell baths 9. In the axle axis 8 (Fig. 3), an axially movable rod 10 with a piston and a spring 11 are installed. The bottom 12 is rigidly seated on the rod 10. The bottom 12 has a conical height 13, and in the lower part of the hollow axis 8 a conical socket N. is made. On the hollow axis 8 a worm gear 15 is set on the key. The rotational drive (Fig. 2) consists of motor 16, gearbox 17c with two output shafts: low-speed and high-speed, couplings 18 and 19 planted on them. On the lower (low-speed) shaft, a worm is set to 20, interacting with a worm gear 15. On the upper (high-speed) shaft 5, a cam 21, is set, interacting with holders 6 of the cubing baths 9. The axle floor is connected by an air line to the inlet fitting 22. The manifold from the choke 22 to the hollow axle 8 is drilled in the frame 1, the struts 2, the axle 3 and the holders 6 (indicated by a dotted line). For transportation, frame 1 has grips 23 and installation supports 24. Bells with inclined rotation axes are located on the proposed device with the open side upwards for easy loading. During operation, the loaded suspension device with mounting supports 2 is laid on the receiving sockets of the baths. Air in the line is missing bottom 12 up. When the electric motor 16 is turned on, rotation at low revs from the gearbox 17 is transmitted through the coupling 18 to the shaft k from the worm to 20, and from the high-speed shaft, the reducer through the coupling 19 rotates the shaft 5 with the cam 21 of the vibrating bell drive. From the screw 20, which interacts with the worm wheel 15, rotates the axis 8 from the floor from the bell bath 9 and the rod 10 connected to it, the spring 11 and the bottom 12. During the period of rotation the bells vibrate as the cam 21 rotating with the high-speed shaft alternately squeezes or brings the bells closer, interacting with the holders 6, The course of the cam 21 provides the allowable release of the worm pair. The closure of the holders 6, on the cam 21 is provided by the weight of the bell and other parts suspended on the holder 6. After the completion of the processing cycle of the parts in the baths, the auto-operator, hooking the grips 23t, moves the device to the unloading position. The device is placed on the receiving slots of the loading rack, so that the fitting 22 is installed and pressed against the source of compressed air. When the compressed air is turned on, the latter, falling into the working space of the axis 8, pushes the rod 10 to the lower position, the conical protrusion 13 is led out from the cage slot 1, the bottom 12 is lowered to the lower position. When the bottom is lowered and the drive is turned on (rotation and vibration), parts are poured into the receiving tank. With the end of unloading, the air supply to the cavity of the rod 10 is stopped, and the porous line is connected to the atmosphere. The spring 1I, pressing the rod 10 to the upper position, lifts the bottom 12 to the bell bath 9. The conical protrusion 13 locks the socket And the hollow axis 8. The bells are loaded with a new batch of parts. The device is transported to the process tanks for the details. The cycle is repeated. The proposed device provides the location of the open side up. When unloading, the lowered bottom and vibration contribute to the sliding of parts along the inclined body of the bell and the bottom - pouring them into the receiving trays. During the period of operation, the vibration of the bells contributes to the disengagement and mobility of parts of practically any configuration, thereby improving the quality of the coating and accelerating the deposition process. The device can be applied on electroplating lines with programmed control, auto-operating and mechanized. The design of the proposed device reduces the labor intensity and speeds up the process of unloading parts at the loading positions of electroplating lines, improves the quality of the applied layer and speeds up (intensifies) the process of electroplating, eliminates the use of special devices - pendants, for processing non-standard types of parts of plugs, petals, special washers, for example, according to GOST 10-663, etc. The economic effect from the use of the proposed device is 5790 rubles per year.
