A kind of clamping device being applied to round plated item
Technical field:
The present invention relates to the technical fields of electroplating device, more specifically to a kind of clamping being applied to round plated item
Device.
Background technology:
Plating is exactly to plate the process of the other metal or alloy of a thin layer on certain metal surfaces using electrolysis principle, is
The technique for making the surface of metal or other materials product adhere to layer of metal film using electrolysis prevents metal oxygen to play
The effects that changing (such as corrosion), improving wearability, electric conductivity, reflective, corrosion resistance (copper sulphate etc.) and having improved aesthetic appearance.It is many hard
The outer layer of coin is also plating.Some cylindrical plated items, which are clamped in also by fixture in electroplating bath, at present is surface-treated,
But existing fixture, when plated item is clamped, retaining part and plated item contact, then retaining part can not be electroplated, existing
Mode, plated item is rechanged into position, is clamped, second time electroplating is carried out, to realize all plating, but this mode is more
Trouble.
Invention content:
The purpose of the present invention and provides a kind of clamping being applied to round plated item aiming at the deficiency of the prior art
Device facilitates the electroplating processes for realizing plated item retaining part.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of clamping device being applied to round plated item, includes the outer frame body of equilateral triangle, the triangle of outer frame body at
Type has journal stirrup, the trigonometric sum journal stirrup of outer frame body to form slot, and clamping piece is plugged in the slot of outer frame body, and clamping piece includes folder
Idler wheel is held, hold-down roll is hinged on by articulated shaft on the bearing of " Fang " shape, and connecting rod is fixed on bearing, and connecting rod is resisted against slotting
On the side wall of slot, guide groove is formed on the connecting rod, and positioning pin, the both ends plugged and fixed of positioning pin are plugged in guide groove
On outer frame body;The connecting rod forms rack away from the side of socket sidewalls, and gear is engaged on rack, and grafting is solid on gear
There are vertical fulcrum, the both ends of fulcrum to be hinged on the journal stirrup of outer frame body, the lower face of the lower end exposing outer frame body of fulcrum is inserted surely
Set is fixed with sprocket wheel, and the sprocket wheel of outer frame body triangle is connected by chain;The upper surface of outer frame body triangle is fixed with column, outline border
Vertical transmission shaft is fixed on the fulcrum that one jiao of body, transmission shaft upper sleeve has several holders, holder sleeve to be fixed on column,
The top of the transmission shaft and the shaft of motor are affixed, and motor is fixed on holder.
Preferably, the central axis of the clamping piece and the center of outer frame body coincide.
Preferably, on the outer frame body slot width be equal to clamping piece upper connecting rod thickness.
Preferably, the width of the clamping piece upper connecting rod is less than the width of bearing.
Preferably, the length of the transmission shaft is less than the length of column.
Preferably, the holder is distributed in the upside of transmission shaft, and transmission shaft is hinged by bearing and holder.
The beneficial effects of the present invention are:Its is simple in structure, is realized to cylindrical electricity using the clamping piece of roller structure
The clamping of plating piece, in electroplating process, plated item can realize that rotation, retaining part are also convenient for carrying out under the effect of external force
Plating.

Specific implementation mode:
Embodiment:See shown in Fig. 1 to 3, a kind of clamping device being applied to round plated item includes the outline border of equilateral triangle
The triangle of body 1, outer frame body 1 forms journal stirrup 11, and the trigonometric sum journal stirrup 11 of outer frame body 1 forms slot 12, and outer frame body 1 is inserted
Clamping piece 2 is plugged in slot 12, clamping piece 2 includes hold-down roll 21, and hold-down roll 21 is hinged on " Fang " shape by articulated shaft
Bearing 22 on, connecting rod 23 is fixed on bearing 22, connecting rod 23 is resisted against on the side wall of slot 12, is molded on the connecting rod 23
There is guide groove 231, positioning pin 5 is plugged in guide groove 231, the both ends plugged and fixed of positioning pin 5 is on outer frame body 1;The company
Bar 23 forms rack 232 away from the side of 12 side wall of slot, gear 3 is engaged on rack 232, there is plugged and fixed on gear 3
The both ends of vertical fulcrum 4, fulcrum 4 are hinged on the journal stirrup 11 of outer frame body 1, and the lower face of outer frame body 1 is exposed in the lower end of fulcrum 4
Sleeve is fixed with sprocket wheel 6, and the sprocket wheel 6 of 1 triangle of outer frame body is connected by chain;The upper surface of 1 triangle of outer frame body is fixed with vertical
Column 7, vertical transmission shaft 8 is fixed on the fulcrum 4 that 1 one jiaos of outer frame body, and 8 upper sleeve of transmission shaft has several holders 9, holder 9 to insert
Set is fixed on column 7, and the top of the transmission shaft 8 and the shaft of motor 10 are affixed, and motor 10 is fixed on holder 9.
Preferably, the center of the central axis of the clamping piece 2 and outer frame body 1 coincides.
Preferably, on the outer frame body 1 slot 12 width be equal to 2 upper connecting rod 23 of clamping piece thickness.
