Description
Technical field
This utility model relates to a kind of flat sanding machine.
Background technology
Sander is a kind of manual power tool that body surface carries out grinding process, and it makes mill rotation continuously and healthily by various drive mechanisms, thus body surface of polishing.Just because of mill rotation continuously and healthily, it can produce bigger heat after rubbing with body surface, make mill hot, on the one hand hot mill works long hours can produce impact to the life-span of mill, on the other hand the body surface polished is caused damage by the too high meeting of its friction temperature, causes unnecessary loss.
Utility model content
This utility model is for deficiency of the prior art, it is provided that a kind of flat sanding machine, and mill is dispelled the heat by automatically, extends mill service life, protects and be polished object from too high the caused damage of mill temperature.
nullFor solving above-mentioned technical problem，This utility model is addressed by following technical proposals: a kind of flat sanding machine，Including mill and the rotating shaft that is connected with described mill，Intake tunnel is offered in described rotating shaft，It is provided with several fixed blocks on described rotating shaft outer wall，Storage cavity is offered in described fixed block，Described storage cavity is connected with described intake tunnel，The flexible ball for blocking described intake tunnel outlet it is provided with in described storage cavity，It is symmetrically arranged with two contiguous blocks on described flexible ball outer wall，It is provided with spring between described contiguous block and described storage cavity inwall，When described rotating shaft is static，Its pulling force is blocked described intake tunnel outlet by described spring by described flexible ball，Described fixed block downside is provided with an outlet pipe，Described storage cavity is interconnected by being opened in the aperture of described fixed block downside with a described outlet pipe，It is rotatably connected to No. two outlet pipes on a described outlet pipe outer wall，No. three outlet pipes it are respectively connected with at the both ends open of described No. two outlet pipes，Described No. three outlet pipe ends connect georama，Described georama internal cavities is interconnected with described No. three outlet pipes，Several ostium excurrenses are offered on described georama.
During use, rotation along with rotating shaft, flexible ball is affected by centrifugal force, side shifting outward, leave the outlet of intake tunnel, its this outlet the most clogging, cooling water enters in storage cavity from exhalant canal, enter in an outlet pipe by aperture again, and enter in georama along No. two outlet pipes and No. three outlet pipes successively, finally throw away at the ostium excurrens offered on georama, fall mill upper side, mill is dispelled the heat, simultaneously, rotating shaft rotarily drive fixed block move in a circle time, No. three outlet pipes by air to No. three outlet pipes and the resistance of georama, No. three outlet pipes are rotated along its being rotationally connected with No. two outlet pipes, when rotation makes cooling water be thrown to mill upper side, fall is more uniform, cooling is evenly.
In technique scheme, it is preferred that being also symmetrically arranged with two pieces of curved baffles on described No. two outlet pipes, described curved baffle is arranged on above described georama.By arranging curved baffle so that cooling water up will not be thrown away by ostium excurrens, it is to avoid cooling water is thrown on the people of work top or staff cause unnecessary trouble.
In technique scheme, it is preferred that being additionally provided with a bracer on described rotating shaft outer wall, described bracer upper side is provided with the semicircle projection leaning described fixed block.Support fixed block by arranging a bracer and semicircle projection, prevent fixed block too big because of the inflow gravity of cooling water, cause fixed block to separate with rotating shaft, affect the normal use of device, the service life of extension fixture.
The beneficial effects of the utility model are: mill is dispelled the heat by this utility model in use automatically, extend mill service life, and protection is polished object from too high the caused damage of mill temperature.
