Description

Technical Field

[0002] A power head is a tool transmission power component that enables the main motion and feed motion. It is also called a power tool holder. The power head is mounted on a power turret and driven by a servo motor. It is also a simple speed change transmission mechanism. The specific principle is that the motor drives the gear speed change mechanism, which in turn makes the spindle rotate to realize functions such as boring, milling, and drilling.

[0003] The power head is driven by a servo motor. The motor shaft transmits power to the power head. When the center lines of the motor shaft and the power head are on the same axis, the length of the motor and the power head is relatively long. This method requires a large space to be left behind the power head, such as 100-300mm. When other mechanical equipment, such as a swivel tool machine, is installed on the machine tool, there may only be 80mm or less space, and the power head that is mounted with the motor cannot be installed, which is a shortcoming.

[0004] When existing servo motors and power heads are connected on the same axis, there is a problem with the assembly design that does not reduce the space occupied by the motor and power head. To address this, this application proposes a power head with the motor pointing upwards. Utility Model Content

[0041] When the drive motor 1 drives the motor shaft 5 to rotate, the bevel gear 8 on the motor shaft 5 rotates, which drives the transition shaft 6 and the bevel gear 8 to rotate, thereby causing the transition gear 9 to drive the main shaft gear 101 to rotate, thus achieving the purpose of driving the main shaft gear 101 to rotate.

[0042] In summary, this application provides an assembly design that reduces the space occupied by the motor and the power head. The drive motor 1 and the power head housing 2 are connected in the vertical direction. When the top of the adjusting screw 43 is rotated under force, the power head housing 2 moves under the action of the screw drive, changing the position of the power head housing 2 and opening the closing plate 25, thereby observing the internal condition of the power head housing 2, which facilitates the maintenance of the transition shaft 6 and the rotating main shaft 10 inside.
