The existing mounting fixture of the stamping deburring device can only clamp a certain type of key column and is not universal. As a result, the fixture needs to be frequently replaced when producing key columns of different models, which is inconvenient. At the same time, due to the close distance between the die and the mounting fixture, it is not convenient and dangerous to place the parts, which urgently needs to be improved. Utility Model Content

[0007] The present invention is further configured as follows: a driving cylinder is provided on one side of the fixture table on the mounting table, and the side surface of the fixture table is connected to the piston rod of the driving cylinder.
[0008] With the above technical solution, since a driving cylinder is provided on the mounting table on one side of the fixture table, and the side of the fixture table is connected to the piston rod of the driving cylinder, after completing the deburring work of the previous part, the fixture table and the fixture plate are pushed to one side together through the driving cylinder, making it convenient to place the next part in the clamping block, solving the problem of difficulty in placing parts due to the fixture plate being too close in the stamping mechanism and the resulting safety problems.
[0009] The present invention is further provided with a discharge hopper fixedly provided on the mounting platform for discharging the key column after deburring.
[0010] With the above technical solution, since a discharge hopper for discharging the key column after deburring is fixedly provided on the mounting table, the parts can be guided by the discharge hopper and directly fall into the collection box after deburring. BRIEF DESCRIPTION OF THE DRAWINGS
