Turret mills, for example, have such a hand wheel which must be rotated, often for many rotations to select the machine tool speed each time a speed change is needed. It is therefore an object of the invention to eliminate manual cranking of hand wheels particularly to changing speed of machine tools.
Another object is to provide a retrofit accessory for conversion of existing machine tools such as turret mills to power tool speed changing. Turret mills, which are sold under the trade name "Bridgeport" as well as other brands, have a variable speed drive comprising variable pitch pulleys which are adjusted by turning a rotatable shaft by a handwheel.
By removing the handwheel and substituting a power drive controlled by an electric switch, the speed change is accomplished rapidly and with no operator stress. A retrofit power drive is attached to the turret mill by a pair of arms or bars which attach to the head of the machine tool and to the power drive. Adjustable connections such as slotted areas for receiving fasteners assist in adapting a given model of accessory to nearly all turret mills.
A spider coupling allows attachment of the power output to the speed control shaft when the output and the shaft are approximately aligned, since the spider coupling permits rotary drive in spite of some misalignment. The power accessory itself has a support frame carrying a motor and a control housing on the outside, and the power output and a belt and pulley drive on the inside.
A first power shaft extends through the housing to carry a first pulley and the input side of a drive coupling, and a manually operable knob or wheel on the outside of the frame. A second power shaft extends through the housing to couple the motor to a second pulley. A drive belt links the pulleys for synchronous rotation.
The motor operates at a constant speed, when energized, and has a speed reducing gearbox at its output to drive the pulleys at a moderate speed. The motor torque is chosen to be low to avoid damage when the position limits of the speed change mechanism are reached.
In the event other torque conditions cause the motor to stall, the manually operated knob is used to momentarily assist the power drive. A pilot light is illuminated when the power is on. The same switch effects overload protection to turn off when the current exceeds a prescribed value. An operator controlled switch is normally in a neutral off position but can be moved in either direction and held there to cause motor operation in either direction for machine tool speed increase or decrease.
When the switch is released it returns to neutral. The above and other advantages of the invention will become more apparent from the following description taken in conjunction with the accompanying drawings wherein like references refer to like parts and wherein:.
