Description
Technical field
The utility model relates to a kind of body of main shaft, specifically a kind of air supporting electricity main shaft body that is used for circuit board processing.
Background technology
Circuit board is of many uses now, and it is more and more stricter to the requirement of the processing of circuit board, singly do not require long-time high-accuracy processing, and require high-speed high strength processing, therefore, someone has proposed air-floating main shaft such as ZL03153311.6 " main shaft device ", it is the air duct generation air suspending power by internal body, and form air bearing rotating shaft is suspended in internal body, make rotating shaft rotate at a high speed with motor stator then, but when main shaft is worked, singly be not that stator produces a large amount of heat, and friction and normal temperature compressed air all can bring certain heat between rotating shaft and compressed air, when long-time intensive work, main shaft accumulates heat too much can make rotating shaft generation seize phenomenon, cause the operating accuracy of air-floating main shaft to reduce, and influence security, moreover this main shaft needs overall time processing, order is produced main shaft and is made troubles, and is not easy to promote and use.
Summary of the invention
Goal of the invention of the present utility model is a kind of body of air supporting electricity main shaft, and it can keep main shaft to work under lower temperature, keeps operating accuracy, and security is good, and body and main shaft are processed assembling more respectively, is convenient to produce, promotes and uses.
Technical solution of the present utility model is on existing overcoat basis, the utility model particularly has the interior cover of tape spool to through hole, interior cover and overcoat interference fit, the interior cover outside is provided with the spirality tank from top to bottom, and interior cover inside is provided with independently axial air feed path and independently axial cooling-water duct; The upper and lower of interior cover inwall is respectively equipped with the radial air through hole that communicates with axial air passage, and the radially cooling water through hole that communicates with axial cooling-water duct; The inside, last top of interior cover is provided with the cooling water feed path that communicates with the spirality tank, and the cooling water return flow line, and interior cover inwall bottom is provided with a radially cooling water through hole that communicates with the spirality tank of interior cover outer lower portion.
Respectively there is a radially cooling water through hole upper and lower of the above body inwall of the present utility model.
Respectively there are two radial air passages the upper and lower of body inwall described in the utility model.
More than of the present utility model have one independently the axial air feed path be arranged in the cover inside.
Described in the utility model have an independently axial cooling-water duct to be arranged on the inside of interior cover.
Put inside, top in above-described a cooling water feed path and a cooling water return flow line are arranged.
Operation principle of the present utility model is that air bearing is installed on the top in the body, and stator is installed at the middle part, and air bearing down, fixed connecting base on the body are installed in the bottom; Feed compressed air from the air inlet of Connection Block, compressed air makes rotating shaft enter duty by the air feed path of body; Lead to into cooling water from the water inlet of Connection Block with the time, cooling water is through each water channel of body, and the delivery port from Connection Block refluxes at last, can keep the operating temperature of main shaft like this.
The utility model has the advantages that to keep main shaft to work under lower temperature, keep operating accuracy, security is good, and body and main shaft are processed assembling more respectively, is convenient to produce, promotes and uses.
