Abstract
The invention discloses a combined type stud welding chuck, which is characterized in that the rear end of a chuck is stretched into a base, wherein the rear end and the base are in threaded fit; a nut sleeve is sleeved on the rear part of the chuck; a thimble passes through the nut sleeve; 2-6 openings which are circumferentially and uniformly distributed are arranged on the front section of the chuck along the axial direction; the front section of the chuck is divided into arc-shaped petals by the openings, and the number of the arc-shaped petals is as same as the number of the openings; the arc-shaped surface on the front part of each arc-shaped petal is provided with an arc-shaped trough along the circumferential direction; an annular groove is formed by all the arc-shaped troughs on each arc-shaped petal; and a spring ring is arranged in the annular groove. The combined type stud welding chuck has the advantages of wide application scope and strong university, can be used for conveniently adjusting the distance between pulling arcs, and can be used for axially and circumferentially limiting the bolts placed into the chuck, thereby ensuring the strength of welding and the stability of welding, meeting the demand of consistent production, only needing to exchange the chuck after the chuck is abraded, and lowering the use cost.
Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, particularly a kind of Combined type stud welding chuck.
Background technology
At present, each automobile production enterprise all need to just can carry out by the stud welding machine of special use when large body panel welding screw.The chuck that existing stud welding machine is used for the clamping screw is monolithic construction, has the following disadvantages:
1) need integral replacing after the chuck wearing and tearing, use cost is higher;
2) screw that chuck can only a kind of specification of clamping, applicable surface is narrow, and versatility is relatively poor;
3) behind the chuck clamping screw, can't to screw axially carry out spacing, screw exposes the arcing spacing that the distance of chuck namely welds and is difficult to control like this, not only can affect the intensity of welding and the stability of welding, and repeat in the continual welding process at streamline, can not guarantee that the arcing distance is constant, not meet the requirement of uniform production;
4) behind the chuck clamping screw, chuck is inadequate to the circumferential enclasping force of screw, causes easily screw loosening, also can affect the quality of welding.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can guarantee the constant Combined type stud welding chuck of arcing distance.
Technical scheme of the present invention is as follows: a kind of Combined type stud welding chuck, comprise base (1), chuck (2), nut sleeve (3), thimble (4), nut (5) and turn (6), the rear end of described chuck (2) is stretched in the base (1), both threaded engagement, be inserted in nut sleeve (3) at the rear portion of described chuck (2), be equipped with thimble (4) in this nut sleeve (3), be threaded connection between described thimble (4) and the nut sleeve (3), locked by nut (5); Leading portion at described chuck (2) offers 2～6 openings (2a) that distribute by even circumferential vertically, this opening (2a) is divided into the arc lobe (2b) that equates with opening (2a) number with the leading portion of chuck (2), the edge circumferentially offers arc-shaped slot (2c) on the cambered surface of each arc lobe (2b) front portion, arc-shaped slot (2c) on each arc lobe (2b) forms an annular groove, and turn (6) is housed in this annular groove.
The present invention removably connects changing screw-type into by traditional monolithic construction between base and the chuck, only needs to change chuck after the wearing and tearing and gets final product, and has greatly reduced use cost.At the rear portion of chuck by the fixing thimble of nut sleeve and nut, the front end of this thimble stretches in the chuck, in the clamping screw, the screw of packing in the front end face of thimble and the chuck connects, thimble is to screw axial limiting, to stretch into the distance of chuck be certain to screw like this, accordingly, it is constant that screw exposes the arcing spacing that the distance of chuck welds during welding, thereby guaranteed the intensity of welding and the stability of welding, particularly repeated in the continual welding process at streamline, kept the arcing distance of screw constant, meet the requirement of uniform production, guaranteed stable welding quality.The parts such as chuck, nut sleeve, thimble and nut integral demounting from the base is got off, pull down again nut, the rotation thimble stretches into the distance of chuck to change thimble, after the suit nut check, integral body is ressembled on the base, can realize the adjusting to welding arcing distance, not only simple, convenient, and enlarged the scope of application of the present invention, so that the present invention can also be applicable to the screw of other specification or random length, satisfied different need of productions.Screw is in the process of chuck of packing into, the elastic force that need to overcome turn opens each arc lobe, behind screw and thimble butt, the elastic force of turn acts on the screw by the arc lobe, each arc lobe is held screw tightly, circumferentially spacing to screw, to prevent screw loosening or rotation, further guaranteed the quality of welding.
The front end of described thimble (4) is pre-small post-large frustum structure, and the frustum of thimble front end has guide effect, can guide the thimble nut sleeve of packing into fast; Contact by face between the end face of thimble front end frustum and the screw, can improve the reliability to screw axial limiting.
Have " one " font groove (4a) in the rear end of described thimble (4), when regulating the arcing distance, the instruments such as employing flat mouth bottle opener insert in " one " font groove of thimble, drive the thimble rotation by instrument, and are convenient and labor-saving like this.
Leading portion at described chuck (2) offers 4 openings (2a) that distribute by even circumferential vertically, just can realize that to cuing open twice processing is very easy to like this on chuck.
Have cannelure (2d) at the middle part of described chuck (2), be provided with the circular hole (2e) that distributes by even circumferential in this cannelure (2d), described circular hole (2e) is corresponding one by one with opening (2a), and circular hole (2e) is connected with corresponding opening (2a).Circular hole is the fabrication hole of processing opening; Root at the arc lobe arranges cannelure, and in the process of the screw of packing in the chuck, the arc lobe opens from cannelure place distortion, and behind screw and thimble butt, the screen resilience of arc lobe self combines with the elastic force of turn, can embrace screw tighter.
The invention has the beneficial effects as follows:
1) only need to change chuck after the wearing and tearing and get final product, use cost is low;
2) base can be equipped with the chuck that a plurality of and different screw specifications adapt, and only needs to change chuck in working service, has greatly saved production cost;
3) can the free adjustment screw stretch into the distance of chuck, it is easy namely to control the arcing spacing, and is applicable to the random length screw, can satisfy different need of productions, widely applicable, highly versatile;
4) can axially reach the screw in the chuck of packing into circumferentially spacing, guarantee the intensity of welding and the stability of welding, particularly repeated in the continual welding process at streamline, can keep the arcing distance constant, guarantee welding quality, satisfied the requirement of uniform production.
