Abstract
The utility model relates to a boxing rotation ground clamp, belongs to the machine equipment field, and is characterized by comprising a wire terminal, a rotary sleeve, a high intensity pressure spring and pressure cover, a screw rod, a thread lock, a locking shaft, a round screw nut, clamp seats, an adjusting bolt and an inner sleeve; the clamp seat is respectively arranged on and under a clamp tool; the rotary sleeve and the wire terminal are arranged near the clamp seat; a front end of the rotary sleeve is provided with the high intensity pressure spring and the pressure cover, a top end of the rotary sleeve is the thread lock, a lower end of the rotary sleeve is the round screw nut, and a middle portion is the locking shaft; the thread lock is connected with the locking shaft through the screw rod; the adjusting screw rod is arranged in a lower portion; the inner sleeve is arranged in an inner side of the clamp seat. The boxing rotation ground clamp is simple in structure, convenient to assembly and dismount, can automatically rotate, and is the boxing rotation ground clamp device with excellent conductivity and firm clamping property.
Description
Technical field
The utility model boxing rotatably wire clamp belongs to plant equipment field, particularly the ground clamp clamping tool of steel pipe circular seam welding.
Background technology
The ground clamp that girth welding post, general workshop is used adopts fixed ground clamp mostly, and this ground clamp is because of can not be synchronously and the rotation automatic rotation of steel pipe, easily cause cable connection post to become flexible and cable torsional deformation, cause losing efficacy, thereby affect welding quality and damage cable; Particularly, in the time producing ocean platform pipe, because of thickness of pipe wall, welding times is many, and ground clamp also needs rotation repeatedly just can complete weld task, and ground wire cable by force distortion coils on ground clamp, causes the accident of forgetting about it electric welding machine.As can be seen here, we need the one can automatic rotation, clamp solid and reliablely, and electric conductivity is good, and the use that aims at large electric current needs and the boxing ground clamp of design.
Utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art part, provides a kind of simple in structure, the ground clamp of automatically selecting.
The purpose of this utility model is that following measures reaches, boxing rotatably wire clamp comprises terminal, rotary sleeve, high strength stage clip and gland, screw rod, screw fastening, fastener shaft, round nut, holder, adjusting screw(rod), inner sleeve, fixture is respectively equipped with holder, other rotary sleeve and the terminal of being provided with of holder up and down, rotary sleeve front end is provided with high strength stage clip and gland, top is screw fastening, low side is round nut, mid portion is fastener shaft, screw fastening is connected by screw rod with fastener shaft, below is provided with adjusting screw(rod), and holder inner side is provided with inner sleeve.
The utility model is simple in structure, ease of assembly and dismounting, automatic rotation, is that electric conductivity is good and clamp firmly boxing welding ground clamp device.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: terminal 1, rotary sleeve 2, high strength stage clip and gland 3, screw rod 4, screw fastening 5, fastener shaft 6, round nut 7, holder 8, adjusting screw(rod) 9, inner sleeve 10.
As shown in Figure 1, the utility model boxing rotatably wire clamp comprises terminal 1, rotary sleeve 2, high strength stage clip and gland 3, screw rod 4, screw fastening 5, fastener shaft 6, round nut 7, holder 8, adjusting screw(rod) 9, inner sleeve 10, fixture is respectively equipped with holder, other rotary sleeve and the terminal of being provided with of holder up and down, rotary sleeve front end is provided with high strength stage clip and gland, top is screw fastening, rear end is round nut, mid portion is fastener shaft, screw fastening is connected by screw rod with fastener shaft, below is provided with adjusting screw(rod), and holder inner side is provided with inner sleeve.Inner sleeve 10 adopts brass bar processing and fabricating to form with fastener shaft 6, strengthens wear-resisting and electric conductivity, and other material is steel.Holder 8 adds round nut 7 with fastener shaft 6 by screw-threaded coupling simultaneously prevents that fastener shaft 6 is loosening because rotating, and inner sleeve 10 is inlayed and is enclosed within on rotary sleeve 2 by interference fit, excessively coordinates with fastener shaft 6; High strength stage clip coordinates the contact-making surface compressing between rotary sleeve and fastener shaft and holder with gland 3 and screw rod 4, improve electric conductivity.In the time of welding, regulate tie down screw 9 to make steel pipe, holder 8 and adjusting screw(rod) 9 close contacts, make ground line current flow to fastener shaft 6 by holder and adjusting screw(rod), flow to rotary sleeve 2 by fastener shaft, because binding post 1 is welded on rotary sleeve 2, ground wire cable is fastened on binding post by screw rod, so electric current flows to ground wire place by rotary sleeve 2 again to binding post 1.Rotary sleeve 2 can be because the deadweight of ground wire cable be taking fastener shaft as axle center automatic rotation with inner sleeve 10.Thereby can automatic rotation while realizing ground wire device welding.
