Abstract

The utility model relates to a cathode clamp which is characterized in that the cathode clamp comprises a cathode clamp bracket, a clamp dolly installed on the cathode clamp bracket, and a clamp subassembly hung on the clamp dolly. The clamp bracket comprises a reducing motor and a belt transmission subassembly which are installed at two sides of the bracket, and a dolly track is arranged between bracket upright posts. The clamp dolly comprises a frame main body and wheels; a small gas cylinder is connected on the frame main body; a threading tube is fixedly installed above the frame main body; and buffers are installed at the front side and the back side of the frame main body. The clamp subassembly comprises a gear and two swing arms, which are connected through a pin roll; a gas cylinder is hinged between the two swing arms; clamp pressure plates are connected at the lower ends of the swing arms; a wire is fixed on the clamp pressure plates through the threading tube and the swing arms. The cathode clamp has the advantages that since the cathode clamp can move together with a core rod, thus ensuring the continuous power supply of the core rod, greatly shortening the distance between the chromeplated cathode and the anode and reducing the heat loss of the current in the wire. Therefore, the cathode clamp improves the electric power utilization ratio and reduces production cost.

Description

The negative electrode clamp

Technical field

The utility model belongs to the plug processing technique field, particularly relates to a kind of plug chromium plating processing negative electrode clamp.

Background technology

Add man-hour in that mandrel surface is carried out chromium plating at present, most plug source mill is general to adopt and copper coil is fixed on the plug afterbody follows together progressive negative electrode form of plug, and this mode needs lead to be connected with copper coil, and the length of lead is wanted sufficiently long.But when plug is carried out chromium plating, at least need two plugs are linked together, the every long 10.6-15m of plug, so the two ends that power cathode directly must be received plug, the length of lead also can the corresponding increase with the quantity of plug like this, because lead is long, and makes very most electric energy all change into heat energy, cause utilization rate of electrical less than 50% like this, and strengthened production cost.In addition, the resistance consumption of lead much electricity, cause electroplating current to reduce, and then be difficult to guarantee the chromium plating quality of plug.

Summary of the invention

The utility model provides a kind of distance between chromium plating negative electrode and the anode, the thermosteresis of minimizing electric current between lead, negative electrode clamp that improves utilization rate of electrical and reduce production costs of shortening for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the negative electrode clamp, it is characterized in that: comprise the negative electrode clamp support that is fixed on the basis, ground, on negative electrode clamp support, the clamp dolly is installed, is lifted with grip module by spring and column on the clamp dolly by track; Described clamp support comprises: in the support both sides reducing motor and belt drive component are installed, are provided with trolley track between support two columns; Described clamp dolly comprises: main body of vehicle frame and wheel, be connected with little cylinder by flange on the main body of vehicle frame, and above main body of vehicle frame, be fixed with penetration pipe by support, the forward and backward both sides of main body of vehicle frame are equipped with the snubber that shields; Described grip module comprises: by gear and two swing arms that bearing pin connects, be hinged with the cylinder that drives its rotation between two swing arms, the swing arm lower end is connected with the clamp press that is used for lead is pressed on mandrel surface.

The utility model can also adopt following technical scheme:

The limit position of control grip module motion and the travel switch that grip module is opened or stepped up to move also are housed on the described clamp backing positions.

Advantage and the positively effect that the utlity model has are: because the negative electrode clamp is to clamp that plug advances and the motion of belt transmission rollback by clamp, so the distance of negative electrode and plug coating bath is a constant.By arranging the negative electrode clamp in plug coating bath both sides, and the action setting-up time of both sides is poor, guarantee the power supply continued power, thereby electric current is received plug two.The current lead length of this electrically conducting manner is constant, and the negative electrode clamp is at the about 6m of the both sides of plug aqueduct spacing, and more than 21m, the resistance of plug is far longer than lead to the distance at plug two ends at least, and this has just significantly reduced the consumption of electric current on plug; In addition, because this negative electrode clamp can together be walked with plug, guaranteed the continuous power supply of plug, make the distance between chromed negative electrode and the anode shorten greatly, the thermosteresis of electric current between lead reduces, and improved utilization rate of electrical, reduce cost, increased benefit.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1-Fig. 8, the negative electrode clamp comprises the clamp support 3 that is fixed on the basis, ground, by cylindrical trolley track 3-3 clamp dolly 2 is installed on the clamp support, and the clamp dolly is a moving parts of realizing that cathode electrode and plug are together walked.Be lifted with grip module 1 by spring 4 and column 5 on the clamp dolly, grip module mainly plays conduction current and adds the effect of holding plug.Described clamp support 3 comprises: by bolt reducing motor 3-1 and belt drive component 3-2 are installed in support 3-4 both sides, are provided with cylindrical trolley track 3-3 between support two columns; The limit position of control grip module motion and the travel switch 3-5 that grip module is opened or stepped up to move also are housed on the described clamp backing positions.Described clamp dolly comprises: main body of vehicle frame 2-1 and wheel 2-5, be connected with stingy cylinder 2-2 by form of flanges on the main body of vehicle frame, be fixed with penetration pipe 2-3 by support above main body of vehicle frame, the forward and backward both sides of main body of vehicle frame are equipped with the snubber 2-4 that shields; Described grip module comprises: by gear 1-1 and two swing arm 1-2 of bearing pin connection, be hinged with the cylinder 1-3 that drives its rotation by two minor axises between two swing arms, the swing arm lower end is connected with the clamp press 1-4 that is used for lead is pressed on mandrel surface by bolt.The lead that rectifier cabinet is drawn is fixed on the clamp press 1-4 by penetration pipe 2-3 and swing arm 1-2.

Principle of work of the present utility model is: by cylinder 1-3 pulling swing arm 1-2, and pass through clamp press 1-4 with lead and mandrel surface clamping, electroplate required electric current and conduct by plug.After grip module clamps plug, grip module 1 and clamp dolly 2 are along with plug moves on trolley track 3-3 together, walk and meet travel switch 3-5 behind the segment distance, cylinder 1-3 on the grip module promotes swing arm and opens, stingy cylinder 2-2 on the clamp dolly depresses, 3-2 pushes down with belt drive component, reducing motor 3-1 rotates and makes grip module and clamp dolly take back starting position by belt drive component, and then stop operating by travel switch control reducing motor, little cylinder lifts, unclamp belt drive component, the cylinder 1-3 pulling swing arm on the grip module compresses plug, the circulation of the next action of beginning.Because the negative electrode clamp is to clamp that plug advances and by the motion of belt drive component transmission rollback, so the distance of negative electrode and plug coating bath is a constant by grip module.
