Detailed description of the invention
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Fig. 1-7, the present embodiment provides a kind of stud positioning apparatus of short period arc stud welding, it comprises positioning collet 1, connecting portion 2 for being connected with welding gun by positioning collet 1, and wherein connecting portion 2 comprises adapter sleeve 20 that an end can be fixedly connected with welding gun, can be movably connected in the positioning sleeve 21 of adapter sleeve 20 the other end along the bearing of trend of adapter sleeve 20, the end be positioned at away from the positioning sleeve 21 of adapter sleeve 20 is provided with porcelain ring 22 and for regulating positioning sleeve 21 along the telescoping mechanism 23 of the bearing of trend telescopic adjustment of adapter sleeve 20.
concrete, positioning collet 1 passes setting from the inside of adapter sleeve 20, positioning sleeve 21 and porcelain ring 22 successively.
adapter sleeve 20 offers the breach 200 be in communication with the outside, this breach 200 is positioned at the relative both sides of adapter sleeve 20, forms opening-wide state after making stud welding gun, is shed by breach 200 so that stud welding gun adds the most of heat produced man-hour.Meanwhile, adapter sleeve 20 is provided with screwed hole 201, by the screw fit of screwed hole 201 corresponding on the rifle body of screwed hole 201 and stud welding gun and corresponding size, whole adapter sleeve 20 is fixed on the rifle body of stud welding gun.
porcelain ring 22 is positioned at the inner and end of positioning sleeve 21 of emerging away from the end of adapter sleeve of positioning sleeve 21.
further, be provided with bayonet socket in the end of positioning sleeve 21, porcelain ring 22 is embedded bayonet socket or is fixed in bayonet socket by outer connector.Common outer connector is as AB glue.
in this example, bayonet socket is stepped, and porcelain ring 22 is provided with the auxiliary section that can embed in bayonet socket.
porcelain ring 22 is provided with groove 220 on the end face of positioning sleeve 21 end of emerging, and the excessive gas in arc stud welding process can be overflowed from groove 220.
in this example, groove 220 has multiple, and is uniformly distributed around the circumference of the end face of positioning sleeve 21 end of emerging., groove 220 is V-shaped.
porcelain ring 22 is RF type porcelain ring (feature of RF type porcelain ring is inwall is through-type, is different from the stepped throughhole of UF type porcelain ring), can be recycled.Because short period arc stud welding is extremely short at 20ms-100ms for process time, reduce the loss of porcelain ring 22, porcelain ring 22 is probably used just to be needed for 200 times about-500 times to change; Substitute mode is broken into pieces by porcelain ring 22 or ejected from the other end (left side) of positioning sleeve 21.
telescoping mechanism 23 comprises an end and is threaded connection regulating sleeve 230 in adapter sleeve 20 the other end (right part), for by relative with adapter sleeve 20 for regulating sleeve 230 retaining ring 231 of locking, wherein positioning sleeve 21 is fixedly connected on the other end (right part) of regulating sleeve 230, and positioning collet 1 passes setting from the inside of adapter sleeve 20, regulating sleeve 230, positioning sleeve 21 and porcelain ring 22 successively.
regulating sleeve 230 material is bakelite, and bakelite material plays heat-blocking action, facilitates workman to grip.
in this example, the taper type connecting portion 230b that regulating sleeve 230 comprises cylindrical connecting portion 230a that an end is threaded with adapter sleeve, the other end (right part) external diameter that is arranged on cylindrical connecting portion 230a diminishes gradually, at the bottom of the cone of taper type connecting portion 230b, external diameter equals the external diameter of adapter sleeve 20, and positioning sleeve 21 is threaded connection at taper type connecting portion 230b.
in addition, annular knurl is provided with in the periphery of retaining ring 231.Anti-skidding, just workers processing rotate this retaining ring 231.
retaining ring 231 inwall processes the screw thread matched with regulating sleeve 230, and outside processes matsurface (annular knurl), so that workers processing rotates this retaining ring 231; The Main Function of retaining ring 231 is the studs for different length, or after porcelain ring 22 wearing and tearing, by rotational lock ring 231, after the length that adjustment regulating sleeve 230 and relative adapter sleeve 20 elongate or shorten, by relative with adapter sleeve 20 for regulating sleeve 230 fixing, be similar to double nut self-locking structure.
in addition, positioner size in the present embodiment, the stud diameter processed as required is determined, generally, for the stud of M6, positioning collet 1 wall thickness of clamping stud is 1mm, after positioning collet 1 clamps screw, diameter is slightly larger than 8mm, now need to adopt internal diameter to be the porcelain ring 22 of 10mm, make the space left between positioning collet 1 and porcelain ring 22 less than 1mm, so both can facilitate the turnover of positioning collet 1, also the stud error of perpendicularity that the error because of positioner assembling is brought can be avoided, heat unnecessary in addition also can be overflowed to the breach 200 of adapter sleeve 20 from here.
therefore, the size of porcelain ring 22, the large footpath of the stud processed as required is mated, under normal circumstances, porcelain ring 22 internal diameter 4mm more than the large footpath of stud.
namely for the stud of M6, the porcelain ring of internal diameter 10mm is selected; For the stud of M8, select the porcelain ring of internal diameter 12mm; For the stud of M10, select the porcelain ring of internal diameter 14mm; For the stud of M12, select the porcelain ring of internal diameter 16mm, by that analogy.
in sum, the utility model adopts above structure, has following advantage:
1, the intrusion of porcelain ring air-isolation, reduce the oxidized degree in deposite metal, welding arc is made to concentrate on weld zone, prevent deposite metal in the loss of weld zone, the shaping of restriction leg, also prevent the carbonization of adjacent domain nonmetallic materials simultaneously, also avoid welder by electric arc burn, decrease the injury of arc light to eyes;
2, in the short period because its process time is very short, porcelain ring is not easily broken, and in production, a porcelain ring can reuse 200 times-500 times.Therefore production cost is greatly reduced, and can not as the production scene of electric arc stud welding because a large amount of broken porcelain rings is made troubles;
3, owing to have employed this corrective measure, this product qualification rate aborning can reach 100% at present, and the national qualification rate such as America and Europe is about 90%;
4, do not need to clean whole finished surface before processing, facilitate production and processing, structure is simple simultaneously, connects steady.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
