According to the technical scheme that the utility model provides, a kind of compulsive-cooling vertical mill spring machine grinding wheel device comprises main shaft, one end of main shaft is provided with check nut, by check nut mounting support dish, be fixed with the emery wheel terminal pad on supporting disk on main shaft, on the emery wheel terminal pad, emery wheel be installed; It is characterized in that: be respectively equipped with the first air vent and the second air vent on described main shaft and check nut, with the emery wheel terminal pad be affixed the unification side supporting disk on be provided with the first air channel that several can ventilate, tow sides at described emery wheel terminal pad are equipped with the second air channel that several can ventilate, and several through holes in axial direction evenly distribute on described emery wheel.
Described emery wheel and main shaft are located at respectively the both sides of emery wheel terminal pad, and the emery wheel terminal pad is isolated with the centre bore of the first air vent on main shaft and emery wheel.
Described the first air vent and the second air vent are connected.
Described the first air channel and the second air vent are connected.
Described the second air channel and the first air channel near supporting disk one side is connected
Described through hole is connected with the second air channel of close emery wheel one side.
The utlity model has following advantage:
1. adopt this grinding wheel unit can effectively improve the emery wheel radiating rate, reduce emery wheel and spring workpiece temperature;
2. this device adopts pressure-air and two-position two-way solenoid valve to control, and guarantees that its ventilation effect is better, energy-saving effect is better;
3. the emery wheel terminal pad is isolated with the centre bore of the first air vent on main shaft and emery wheel, avoids dust to fall in supporting disk;
4. this apparatus structure is simple, slightly does to change in existing vertical mill spring machine structure and just can realize its purpose.
Description of drawings
Fig. 1 is the grinding structure schematic diagram of vertical mill spring machine described in the utility model.
Fig. 2 is the structural representation of compulsive-cooling vertical mill spring machine grinding wheel device described in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 2, described compulsive-cooling vertical mill spring machine grinding wheel device comprises emery wheel 1, emery wheel terminal pad 2, check nut 3, supporting disk 4, main shaft 5, the first air vent 6, the second air vent 7, the first air channel 8, the second air channel 9, through hole 10 etc.
The utility model comprises main shaft 5, and an end of main shaft 5 is provided with check nut 3, is respectively equipped with the first air vent 6 and the second air vent 7, the first air vents 6 and the second air vent 7 on main shaft 5 and check nut 3 and is connected; By check nut 3 mounting support dishes 4, be fixed with emery wheel terminal pad 2 on supporting disk 4 on described main shaft 5, be provided with several 8, the first air channels 8, the first air channel that can ventilate on the supporting disk 4 of unification side and be connected with the second air vent 7 being affixed with emery wheel terminal pad 2; The tow sides of described emery wheel terminal pad 2 are equipped with several second air channels 9 that can ventilate, and the second air channel 9 and first air channel 8 of close supporting disk 4 one sides are connected; Emery wheel 1 is installed on described emery wheel terminal pad 2, several through holes 10 that in axial direction evenly distribute on emery wheel 1, through hole 10 is connected with the second air channel 9 of close emery wheel 1 one sides;
