Technical field
The present invention relates to a kind of mill spring machine grinding wheel device, especially a kind of compulsive-cooling vertical mill spring machine grinding wheel device.
Background technology
Vertical grinding machine with double end faces mill spring machine is the capital equipment of spring end face grinding, and spring end face grinding is an important procedure in spring process.Its structural principle is: spring is placed in charging tray, and charging tray is between upper and lower emery wheel, and when grinding, charging tray, upper and lower emery wheel rotate simultaneously, moves up and down feeding to reach the object of grinding spring biend by emery wheel.People, in process, adopt the rotating speed that improves abrasive grinding wheel or the amount of feeding that strengthens abrasive grinding wheel in order to enhance productivity, all, because the excess Temperature of abrasive grinding wheel makes spring end face lower hardness, cause spring failure.Abrasive grinding wheel temperature is the Main Bottleneck of restriction grinding efficiency at present, and cool-down method is extremely passive, dispels the heat by the equally distributed aperture of emery wheel one side (illogical) completely, and poor effect, is also the weak point of existing vertical mill spring machine.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of compulsive-cooling vertical mill spring machine grinding wheel device is provided, this device can reduce the rate of rise in temperature of emery wheel in grinding process effectively, ensure to improve the grinding efficiency of spring and the grinding quality of spring on existing structure, can also reduce the grinding loss of emery wheel simultaneously, there is the advantages such as energy-conservation, consumption reduction, synergy.
According to technical scheme provided by the invention, 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, on main shaft, by check nut mounting support dish, on supporting disk, be fixed with emery wheel terminal pad, on emery wheel terminal pad, emery wheel be installed; It is characterized in that: on described main shaft and check nut, be respectively equipped with the first air vent and the second air vent, be affixed on the supporting disk of unifying side and be provided with the first air channel that several can ventilate with emery wheel terminal pad, be equipped with at the tow sides of described emery wheel terminal pad the second air channel that several can ventilate, on described emery wheel, be in axial direction uniformly distributed several through holes.
Described emery wheel and main shaft are located at respectively the both sides of emery wheel terminal pad, and emery wheel terminal pad is by isolated 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 near emery wheel one side.
The present invention has the following advantages:
1. adopt this grinding wheel unit can effectively improve emery wheel radiating rate, reduce emery wheel and spring workpiece temperature;
2. this device adopts pressure-air and two-position two-way solenoid valve control, ensures that its ventilation effect is better, energy-saving effect is better;
3. emery wheel terminal pad, by isolated 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 changes and just can realize its object in existing vertical mill spring machine structure.
Brief description of the drawings
