Description

Novel spot welding solder joint remover
Technical field
The utility model relates to a kind of welding machine tool, is specifically related to a kind of Novel spot welding solder joint remover.
Background technology
In automotive body welding is produced, part position occuring sometimes weld incorrect problem, and for the solder joint of malposition, must take the measure of reprocessing that solder joint of its wrong weldering is removed, could use after again welding, processing.Be that electric drill directly cuts the part nugget in the solder joint dismounting mode of reprocessing middle employing at present, but the hardness of the nugget that forms under the process HTHP is all higher, usually to weld circumnuclear sheet material hardness high by about 30% for the hardness ratio that merges of solder joint, therefore the operating efficiency that directly uses drill bit to cut is extremely low, and wear damage usually occurs in drill bit, reprocess efficient low especially, reprocess cost high.In addition, the specification requirement of operation is also very high.
A grant number notification number is CN 201505751 U, and the patent of patent weldering by name cutting drill head discloses a kind of opening bit.It comprises cutter head, knife bar, handle of a knife, and interior cold hole is arranged in knife bar and handle of a knife, has chip area on the knife bar, the casting integrated moulding of described knife bar and handle of a knife, and described cutter head is carbide bit, this cutter head is welded on the knife bar end.This technical scheme has been saved cost to a certain extent, but does not perform to advantage in its operation to the weld zone, can not solve hereinbefore described problem.
The utility model content
The purpose of this utility model is in order to solve at present in the time must again welding because the welding position is inaccurate, and the dismounting inefficiency of butt welding point, operating technology require problem high and that running cost is high, and a kind of Novel spot welding solder joint remover is provided.
The utility model is carried out by following scheme:
A kind of Novel spot welding solder joint remover, described Novel spot welding solder joint remover comprises installing handle and the bit head that is connected with it, described bit head comprises fixed part and the drill bit that is connected with it, described drill bit is comprised of the location drill bit at center and the hollow boring bit of peripheral tubular, the location drill bit is positioned at the center of hollow boring bit inside, the length of location drill bit is greater than the length of hollow boring bit, and the front portion of hollow boring bit is installed with locating ring.Because the hardness of the nugget that forms under the process HTHP is all higher, therefore when taking out nugget, can not directly cut nugget, adopt the location drill bit to position in nugget in this programme, then will weld circumnuclear non-nugget place with circular hollow boring bit excises, thereby avoided the higher nugget of hardness, increase operating efficiency, reduced operation easier.And the procephalic spacing ring of core drill can be controlled the punching degree of depth of hollow boring bit, prevents from punching deeply damaging miscellaneous part.
As preferred version, the long 0.2 ~ 0.5mm of the length of the Length Ratio hollow boring bit of location drill bit.Because the location drill bit will position, thereby prevents departing from of whole device, therefore the location drill bit should touch nugget in advance than hollow boring bit in operating process.
As preferred version, the inside center of the link of described fixed part and bit head is provided with the fixing hole that will insert and be fixed locating drill bit for locating drill bit, the sidewall of fixed part is provided with the locking hole that connects with fixing hole, and the location drill bit inserts locking hole by locking nail and is fixedly connected with fixed part.Because nugget hardness is higher, therefore locate drill bit and easily be damaged, lock the replacing that can realize locating drill bit by adopting locking nail will locate drill bit, thereby increase the practicality of whole device.
As preferred version, described bit head and installing handle are integrated.
As preferred version, hollow boring bit and fixed part are integrated.
As preferred version, described installing handle outer wall is provided with anti-slip veins.Increase the stability in the operation of installing handle after installation.
As preferred version, the termination of hollow boring bit is provided with cutting blade, and the external diameter of cutting blade is greater than the main body external diameter of hollow boring bit.After the cutting blade external diameter is slightly large, be convenient to the activity of hollow boring bit rear portion main body, prevent that the hollow boring bit main body from causing the generation of chucking phenomenon in operation.
Owing to adopting technique scheme, the beneficial effects of the utility model are: in the time must again welding because the welding position is inaccurate, operating personnel are higher to the removal efficient of weld, operating technology requires lower, whole running cost is lower, and the design of spacing ring can also prevent from damaging miscellaneous part in boring procedure in addition.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1 installing handle, 2 bit head, 3 fixed parts, 4 drill bits, 5 location drill bits, 6 hollow boring bits, 7 fixing holes, 8 locking holes, 9 locking nails, 10 cutting blades, 11 spacing rings.
The specific embodiment
The below is described further the utility model with specific embodiment.
A kind of Novel spot welding solder joint remover, as shown in Figure 1, it comprises installing handle 1 and the bit head 2 that is connected to one with installing handle 1, the outer wall of installing handle 1 is provided with installing handle 1 is carried out stable anti-slip veins, bit head 2 comprises fixed part 3 and the drill bit 4 that is fixedly connected with bit head 2, drill bit 4 is comprised of the location drill bit 5 at center and the hollow boring bit 6 of peripheral tubular, location drill bit 5 is positioned at the center of hollow boring bit 6 inside, and the long 0.2 ~ 0.5mm of the length of the Length Ratio hollow boring bit 6 of location drill bit 5, the front portion of hollow boring bit 6 is provided with a spacing ring 11, spacing ring 11 is connected the control that realizes hollow boring bit 6 drilling depths with hollow boring bit 6 by screw thread, the dark miscellaneous part that damages prevents from holing.Location drill bit 5 all is fixedly connected with fixed part 3 with hollow boring bit 6, wherein hollow boring bit 6 is structure as a whole with fixed part 3, and location drill bit 5 is dismountable fixed connection structures, specific design is: fixed part 3 offers one for the fixing hole 7 that will locate drill bit 5 insertions and location drill bit 5 is fixed with the inside center of the link of bit head 2, offer a locking hole 8 that is communicated with fixing hole 7 on the sidewall of fixed part 3, location drill bit 5 inserts locking hole 8 by locking nail 9 and is connected with fixed part 3.
