Description
Technical field
It the utility model is related to automobile exhaust pipe field, more specifically to a kind of deburring for automobile exhaust pipe
Device.
Background technology
With industrial expansion, various automatic casing cutters arise at the historic moment, and pipe cutting machine is in cutting process to exhaust tubing tool
There is the power pushed, can discharge heat in cutting process, cause small radial deformation of the blade during pushing at the mouth of pipe, it is right
For the relatively thin blast pipe of tube wall, radial deformation is more serious, in automobile industry, often occurs that pipe pipe connects, Guan Guan
Section of a pipe is generally inserted into other end pipe by connection, then is welded, and the deformation of radial direction can cause the difficulty of insertion,
Welding inconvenience, not prison welding are solid when welding simultaneously；In addition, automobile exhaust pipe is after pipe cutting machine cuts into specification part, incision meeting
Burr is produced, worker needs to be removed the burr of incision.
Traditional burr removing method, by the way of artificial deburring, efficiency is low, and relatively advanced mode is gone for machinery
Burr, during deburring, the inwall of cutter line up and outer wall are carried out deburring by generally use 2 respectively, at the mouth of pipe
Radial deformation can cause to remove excessive or not remove clean phenomenon.
Utility model content
The defects of for prior art, the purpose of this utility model are to provide a kind of deburring for automobile exhaust pipe and filled
Put, mouth of pipe rounding, the used time is less, deburring efficiency high, and blast pipe qualification rate is high.
Above-mentioned technical purpose of the present utility model technical scheme is that：One kind is used for automobile exhaust
The burr remover of pipe, it is characterised in that including mounting bracket, the motor being located on the mounting bracket and the motor connection
Output shaft with it is described output axis connection handler connect with the handler can to the blast pipe mouth of pipe progress shaping and
Carry out the deburrer of deburring simultaneously to exhaust tube wall and inwall, fixed block is additionally provided with the mounting bracket, it is described
Bearing is provided with output shaft, between the motor and the handler, the bearing is fixed on described solid the bearing
Determine in the bearing mounting hole in block.During installation, output shaft is connected by shaft coupling with machine shaft, this burr remover, no longer
Using the method for directly using cutter deburring in the prior art, but by carrying out deburring action after mouth of pipe shaping again, pipe
Mouth more rounding, improves the qualification rate of blast pipe, and the mouth of pipe more rounding, can further improve deburring efficiency effect,
Reduce and removed when deburring caused by mouth of pipe radial deformation excessively or remove sordid risk, in addition, to outer wall and inwall
Deburring is carried out simultaneously, the used time is less, improves deburring efficiency.During work, motor rotates, and by a series of transmission, realizes
The rotation of deburrer, in addition, fixed block and the bearing fit on output shaft, effectively reduce output shaft run-out, protect
Demonstrate,prove the deburring effect of deburrer.
