Problems solved by technology
In the prior art, the chamfering of the tool is usually driven by a reducer, and the reducer itself has a large volume; in order to enable the tool to enter the cavity of the door closer and reach the small hole, a longer tool rod must be provided; the above Two factors make the overall volume of the chamfering machine very large, occupy a large space, and the stability is not good
One chamfering machine can only process one door closer at a time, the speed is slow, the time is long, and the processing efficiency is low

The invention discloses a chamfering machine for a door closer, which comprises a frame, a plurality of chamfering mechanisms arranged on the frame, and a transmission shaft driven by a motor, and the chamfering mechanism includes a For the guiding mechanism for sliding the door closer, the clamping mechanism for clamping the door closer, the knife rod, and the tool, the transmission shaft is provided with a plurality of active bevel gears coaxially and spaced along its axial direction, The cutter bar has opposite first ends and second ends, a driven bevel gear is fixedly connected to the first end, a cutter is arranged on the second end, and the driven bevel gears on each cutter bar They are respectively meshed with one of the driving bevel gears, the guide mechanism passes under the clamping mechanism, and the cutter rotates with the cutter bar and can extend into the hole to be chamfered in the door closer. The object of the present invention is to provide a chamfering machine for door closers, which has multiple stations and has high processing efficiency.
Description
technical field [0001] The invention relates to a chamfering machine, in particular to a chamfering machine for a door closer. Background technique [0002] The basic function of the door closer is to automatically close the door, and it can also be closed smoothly to protect the door frame and door body. Since the inner chamber of the door closer is filled with hydraulic oil, the housing of the door closer is usually provided with a plurality of small holes for hydraulic oil or air circulation, and some of the small holes are located at deeper positions in the cavity. In the prior art, the chamfering of the tool is usually driven by a reducer, and the reducer itself has a large volume; in order to enable the tool to enter the cavity of the door closer and reach the small hole, a longer tool rod must be provided; the above Two factors make the overall volume of the chamfering machine very large, occupy a large space, and the stability is not good. One chamfering machine...
