Description

The Chip-R end face is coated with the clamping device of silver-colored equipment

The utility model relates to the silver-colored equipment of being coated with of a kind of resistance.

In the prior art, coat certain thickness silver slurry, ceramic positive carbon resistance and back side pin are worked by silver slurry conduction at ceramic paster resistance two ends.Finishing this function at present has two kinds of methods, and the one, the method for employing vacuum plating; The 2nd, the manual method that is coated with silver.When adopting the method for vacuum plating, because requirement is packed Chip-R among a kind of special tool for the vacuum plating use in advance, and this loading procedure is relatively more difficult, speed is slower, be subjected to the influence of this factor, the efficient of vacuum plating is lower, can't satisfy the needs of resistance industry large-scale production.And the manual range request workman that crosses who is coated with silver all adopts manual mode to finish to pick up the material casket, and be positioned in the anchor clamps and clamp, on Tu Yinmian, dip in then and get the silver slurry, and starch in ceramic paster resistance one end silver coating, subsequently anchor clamps are opened, take out the material casket, treat after the silver slurry drying again stirring and repeat above action, promptly at the other end silver coating slurry of ceramic paster resistance.Because the clamping degree difference of anchor clamps, cause the inclination of material casket easily, thereby cause a part of Chip-R to be coated with the quantity not sufficient of silver slurry, the silver slurry is not connected and scraps, another part Chip-R again can be too many because of silver coating slurry, makes silver slurry seepage flow cross ceramic positive carbon resistance and scrap.Manually open, the clamping device time and effort consuming.

The purpose of this utility model is to provide a kind of can clamp the clamping device that the Chip-R end face that carries out the silver coating slurry is coated with silver-colored equipment to the material casket automatically.

The technical solution of the utility model is: a kind of Chip-R end face is coated with the clamping device of silver-colored equipment, it comprises base plate, jacking cylinder, the cross-bridges that is connected with the telescopic cylinder of described jacking cylinder, the guide holder that is fixedly connected with described cross-bridges, the lift frame that is connected with described cross-bridges elasticity, be elasticly connected with push rod on the described guide holder, described lift frame is provided with a pair of jig arm, be respectively equipped with relative jaw on this a pair of jig arm, be provided with the clamping cylinder between described jig arm and the described lift frame.

The utility model compared with prior art has following advantage:

Used a jacking cylinder to play and risen or the decline effect, made mechanism simple, chucking power relies on and clamps cylinder, makes jaw can produce uniform chucking power, can the run-off the straight phenomenon, the automatic clamping that has realized anchor clamps simultaneously with open.
