Abstract
The utility model discloses a components of a whole that can function independently swift current bits formula projection welding bolt bottom electrode, including the electrode body, the electrode body is including the electrode sleeve that is equipped with the screw rod jack, lower electrode body and the insulating cover that is equipped with the transition hole, insulating cover is located the screw rod jack, electrode body upper end still is equipped with the spliced eye down, the lower extreme of electrode sleeve is located the spliced eye, be equipped with at least one chip removal passageway down on the electrode body, the chip removal passageway advance the bits end with go out the bits end respectively with transition hole and electrode body outside intercommunication down. The utility model discloses an adopt the components of a whole that can function independently structure of electrode cover and lower electrode body, only consume the electrode cover and needn't consume whole lower electrode body, the chip removal passageway that sets up moreover can discharge smoothly the weldment material piece that the sword was scraped down, has improved the life of bottom electrode, the cost is reduced.
Description
Technical field
The utility model relates to weld car projection welding field, is specially a kind of split slide bits formula projection welding bolt bottom electrode.
Background technology
Projection welding is to process in advance one or more protruding points on the binding face of a weldment, make the heating that contacts and switch on of itself and another weldment surface, then press and collapse, make these contact points form the electric resistance welding method of solder joint, the projection welding bolt bottom electrode is the electrode body that directly contacts with weldment in welding process.But, after being welded to certain counting, under the environment of high pressure, high heat, the contact surface of electrode body and weldment easily produces the alloy surface that is impregnated with the weldment material, thereby affect welding quality, because electrode body is an integral body, so must change whole electrode body, very waste after the loss.And, when repairing, easily falling in the hole of electrode body with frustrating the weldment material chip that cutter scrapes, therefore existing electrode body service life is low, it is large to consume.
Summary of the invention
The purpose of this utility model is to provide a kind of split of simple in structure, long service life to slip bits formula projection welding bolt bottom electrode in order to overcome above-mentioned deficiency.
The utility model comprises electrode body, described electrode body comprises the electrode sleeve that is provided with the screw rod jack, bottom electrode body and the insulation sleeve that is provided with transitional pore, described insulation sleeve is positioned at the screw rod jack, and described bottom electrode body upper end also is provided with spliced eye, and the lower end of described electrode sleeve is positioned at spliced eye.
Described bottom electrode body is provided with at least one channel of chip removal, and advancing the bits end and going out the bits end of described channel of chip removal is communicated with transitional pore and the external side of bottom electrode respectively.
Described channel of chip removal is to be higher than being obliquely installed of bits end into the bits end.
Described electrode sleeve outer surface is provided with the V-ring groove.
Described screw rod jack inwall and insulation sleeve interference fit.
The utility model is by adopting the Split type structure of electrode sleeve and bottom electrode body, only sacrificial electrode overlaps and needn't consume whole bottom electrode body, and the channel of chip removal that arranges can discharge smoothly with frustrating the weldment material chip that cutter scrapes, and improved the service life of bottom electrode, reduced cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-electrode sleeve (11-screw rod jack, 12-V shape annular groove), 2-bottom electrode body (21-transitional pore, 22-spliced eye, 23-channel of chip removal), 3-insulation sleeve
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: the utility model comprises electrode body, described electrode body comprises the electrode sleeve 1 that is provided with screw rod jack 11, the bottom electrode body 2 that is provided with transitional pore 21 and insulation sleeve 3, described insulation sleeve 3 is positioned at screw rod jack 11, described screw rod jack 11 inwalls and insulation sleeve 3 interference fit, described bottom electrode body 2 upper ends also are provided with spliced eye 22, and the lower end of described electrode sleeve 1 is positioned at spliced eye 22.Described bottom electrode body 2 is provided with two channel of chip removal 23, advancing the bits end and going out the bits end of described channel of chip removal 23 is communicated with transitional pore 21 and bottom electrode body 2 outsides respectively, described channel of chip removal 23 is to be higher than being obliquely installed of bits end into the bits end, makes things convenient for like this chip to discharge smoothly from channel of chip removal 23.Described electrode sleeve 1 outer surface can also arrange the degree of wear that V-ring groove 12 is used for sign electrode sleeve 1.
During use, bolt shank to be welded is inserted in the screw rod jack 11, then compresses, make welding current pass through bolt head, heat production forms nugget, cuts off welding current, and pressure continues to be maintained until nugget and is solidified to sufficient intensity.
After using repeatedly, the degree of wear of electrode sleeve 1 can be found out according to the change of shape of V-ring groove 12, just electrode sleeve 1 replacing can be taken off if need.
