Detailed Description

Reference numerals: 1, a motor; 2, fixing a plate; 3, a screw rod; 4, guide pillars; 5 a movable plate; 6. 7, measuring a head; 8, a sleeve; 8.1 through grooves; 8.2 a movable rod; 8.3, arranging a positioning bulge; 8.4 air inlet holes; 8.5 blowing head; 8.6 air outlet holes; 8.7 a spring; 10 bearing.

A device for measuring hole with air blowing comprises a motor 1, a fixed plate 2, a guide post 4 fixed with the fixed plate 2, a screw rod 3 driven by the motor 1 and a movable plate 5 driven by the motor and the screw rod, wherein the movable plate 5 can move up and down along the guide post 4; the portable plate 5 department is fixed with the unit of blowing, the unit of blowing include with sleeve 8 that the portable plate is fixed and insert sleeve 8 can reciprocate movable rod 8.2 in sleeve 8, the tip of movable rod 8.2 is fixed with blowing head 8.5, still have the spring that is located the movable rod top in the sleeve 8.

The guide pillar has 2. The movable rod 8.2 is provided with an air inlet 8.4 which can be connected with an air inlet pipe, the movable rod 8.2 is also provided with an inner cavity communicated with the air inlet, and the blowing head 8.5 is provided with an air outlet channel communicated with the inner cavity and an air outlet communicated with the air outlet channel. The blowing head 8.5 and the movable rod 8.2 are fixed through bolts. The air outlet holes are distributed in an annular array, and the included angle formed by the axis of each air outlet hole and the axis of the air outlet channel is larger than 20 degrees and smaller than 70 degrees. The telescopic lateral wall has the logical groove of vertical bar, the lateral wall of movable rod has spacing arch and lower spacing arch of going up, go up spacing arch and lower spacing arch and all be located the logical inslot of bar.

The utility model discloses a gas blowing device, among the automatic bearing detection device of mainly used, as shown in figure 1, the bearing is accomplished one process from a station under the effect of manipulator and is removed next process again, specifically as shown in figure 1, blows in the blowing head below, blows off dust impurity etc. carries out the measuring of internal diameter through gauge head 6 and gauge head 7 below after that. Specifically, the movable plate can move up and down under the driving of the motor and the screw rod, when the movable plate moves down to a set position, the bearing is blown, the blowing head has certain upper and lower movable spaces due to the fact that the spring is arranged in the sleeve, air flow (generated by an external air pump) enters the inner cavity of the movable rod through the air inlet hole, then enters the air outlet channel, then comes out from each air outlet hole, and dust on the bearing is blown off. When the blowing head moves to the lower position to be in contact with a product, the electromagnetic valve acts to blow the inner hole of the product through the blowing head, and the blowing time can be set through the touch screen.

Although the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
