At present, the chucking power of the welding rod of electrode holders clamping is both at home and abroad the cylindrical compression spring from traditional structure, this cylindrical compression spring is fixed on and utilizes the hinged upper watch box handle end of connecting axle and curved between body end, forms the welding rod chucking power of the upper and lower jaw of electrode holders therebetween by the folding power producing.Nonadjustable once assembling cylindrical compression spring range height.Electrode holders, under the long-term service condition of the frequent folding of jaw and variations in temperature, reduce gradually along with the fatigue of cylindrical compression spring can make the welding rod chucking power of electrode holders.Because the welding rod chucking power of jaw reduces gradually, will be not enough to firmly clamp welding rod and carry out weld job, so have a strong impact on the service life of electrode holders.In addition, the jaw folding power that cylindrical compression spring after assembling has electrode holders within a period of time, though can keep clamping certain chucking power of welding rod, but different physique operating personnel's hand faces same opening and power, for the less operating personnel of strength, use for a long time electrode holders will feel hand fatigue.Because traditional cylindrical compression spring of existing electrode holders adopts the nonadjustable structure of range height, so existing electrode holders can not solve the problem that cylindrical compression spring fatigue reduces welding rod chucking power gradually, also cannot meet the different physique crowds of adaptation and carry out the requirement of weld job.
Utility model content
The purpose of this utility model is to provide a kind of anti-tired adjustable electrode holder, having solved cylindrical compression spring fatigue reduces gradually welding rod chucking power and uses electrode holders susceptible to problems such as hand fatigues, its reasonable in design, adjust the processing ease that cylindrical compression spring has the welding rod chucking power needing, not only improve the service life of electrode holders, and the different physique crowds of satisfied adaptation carry out the requirement of weld job.
The technical scheme that the utility model adopts is: this anti-tired adjustable electrode holder comprises and utilizes the hinged upper watch box assembly of connecting axle and curved body assembly, together with upper clamp nozzle in upper watch box assembly passes through screw fastening with upper watch box, curved the lower clamp nozzle in body assembly with curved body by together with screw fastening, its technical essential is: the cylindrical compression spring that the generation folding power of assembling by adjusting bolt is set between described upper clamp nozzle and lower clamp nozzle, adjusting bolt is passed the through hole of the upper clamp nozzle that is assembled with cylindrical compression spring, be threaded in the screwed hole that is positioned at the lower clamp nozzle of same axis with upper clamp nozzle through hole, rotation adjusting bolt is along on lower clamp nozzle screwed hole axis, under move back and forth, the range height of adjusting cylindrical compression spring reduces or increases.
Advantage of the present utility model and positive technique effect are: due to the cylindrical compression spring of the generation folding power of assembling by adjusting bolt being set between the utility model upper clamp nozzle and lower clamp nozzle, by rotating adjusting bolt along on lower clamp nozzle screwed hole axis, under move back and forth, the range height of adjusting cylindrical compression spring reduces or increases, can lower economize on electricity soldering turret in the situation that does not affect welding rod chucking power and there is suitable folding power, can be under the effect of hand strength, make on electrode holders, lower clamp nozzle is clamped welding rod and is carried out weld job, so its reasonable in design, adjust the processing ease of cylindrical compression spring, on adjusting at any time, between lower clamp nozzle, keep having the welding rod chucking power needing.The cylindrical compression spring that the utility model has solved traditional electrical soldering turret is non-adjustable once assembling range height, because cylindrical compression spring is tired, welding rod chucking power is reduced gradually, welding rod clamps not strongly, therefore cause weld job to carry out, affects the electrode holders problem in service life.In addition, rotation adjusting bolt can regulate the range height of cylindrical compression spring at any time, makes it, the in the situation that of firm grip welding rod, the folding power of electrode holders being transferred to optimum state, to alleviate the fatigue of operating personnel's hand that strength is less, to enhance productivity.Therefore, the utility model not only can extend the service life of electrode holders, and can meet adapt to different physique crowds carry out the requirement of weld job.
