Milling machine is opened, the path of milling cutter is adjusted, metal derby is processed, while machining, removed, the one end that will be processed
It is placed in L shaped plate, clamps, process unfinished one side, machines rear opposite direction and rotate adjustment gear, make two pieces of L shaped plates
It is away from each other movement, you can remove the heat sink processed.
The beneficial effects of the utility model are：The processing unit (plant) of the utility model, by design an adjustable berth away from
Clamping body, the clamping body are made of two pieces of L shaped plates adjusted by adjustment gear adjusting gear rack, by rotating adjustment gear, i.e.,
The clamping size of clamping body can be adjusted, to adapt to the process requirements of sizes metallic heat radiating plate.
Preferred solution one, the position that the L shaped plate is contacted with parts to be processed are equipped with cushion, spread all on the cushion
There are the hemispherical projections made of flexible material.When rotating adjustment gear to adjust the clamping of L shaped plate, since stress is excessive,
The surface of metal derby can be caused to damage, in order to avoid the generation of the phenomenon, by by hemispherical projections made of flexible material
Spread over the position that L shaped plate is contacted with parts to be processed, there is provided a cushion effect, buffers nip stress, avoids the table of metal derby
Face is damaged.
Preferred solution two, is connected with spring between two pieces of L shaped plates.Similar, by being connected with bullet between L shaped plate
Spring, utilizes the elastic deformation of spring, there is provided a cushion effect, buffers nip stress, avoid the surface of metal derby from being damaged.
For the improvement of preferred solution one and preferred solution two, the hollow hole of multiple strips is provided with the L shaped plate.
To mitigate the overall weight of fixture, while the dust of Milling Machining is also avoided to be gathered in L shaped plate.
Further, the number of the positioning fixture is two, and two positioning fixtures are oppositely arranged.In the heat dissipation that needs are processed
When plate is sufficiently large, the most of area that can make heat sink using a positioning fixture exposes in outside, therefore cannot meet
Clamping demand, i.e., can make clamping unstable, therefore by setting two opposite positioning fixtures, it is ensured that the stabilization of heat sink.
Further, offered on the milling machine table between two positioning fixtures and collect hole, collection hole connection
Dust collecting system, the dust collecting system include dust hood, sweep-up pipe, wind turbine and detachable collection box.In Milling Machining
When, substantial amounts of metallic dust can be produced, if these metallic dusts are not handled, is entered inside pedestal, can influence to adjust tooth
The rotation of bar, and then influence clamping effect.
Further, the adjustment gear is equipped with the regulation handle through pedestal.Regulation handle is arranged on outside, convenience pair
In the operation of adjustment gear.
Further, pedestal is equipped with the limit card block for preventing that regulation handle from rotating.When clamping, adjust in order to prevent
Gear rotate, by setting limit card block, make adjustment gear by well it is spacing live.
Further, the size of the milling cutter is less than the size of hollow hole.When being processed to heat sink, due to heat sink
It is stacked, the setting of hollow hole can make milling cutter pass through hollow hole, and directly metal derby is processed.
