Description

Technical Field

[0001] The utility model relates to a field, in particular to a precision boring fixture for a turret box. Background Art

[0002] The turret housing is a key component in a milling-turn machine tool. Its structural design and operating principle are crucial to the machine's overall performance. In traditional turrets, the motor is typically located outside the housing, transmitting power to the drive shaft via a timing belt. The drive shaft's end is fixedly connected to the first gear, while the cutterhead is fixedly connected to the second gear. The first and second gears mesh, so that when the motor rotates, the cutterhead rotates. The control unit uses feedback from the motor's built-in encoder to adjust the motor's speed, number of revolutions, and rotation angle, achieving precise control of the cutterhead's rotation. The toolholder is secured to each tool position around the cutterhead using locating keys and screws. Either a turning tool or a boring tool can be mounted on the toolholder. This design changes the traditional tool mounting arrangement of the turret, allowing each position to accommodate both turning and rotating tools. The turret housing design fully considers transmission efficiency, stability, and control accuracy, providing a strong guarantee for efficient and precise machining.

[0003] The existing turret box processing is mainly completed through the machining center and clamped with universal fixtures. However, universal fixtures have the following disadvantages: 1. The accuracy of parts is unstable, and the center height of holes bored out of the same batch of parts is inconsistent; 2. The efficiency is low, the position stability is poor, and the position of the same height fluctuates greatly; 3. The use of a dial indicator for alignment and repeated tool setting are required, which increases the labor intensity of the operators; 4. The accuracy of parts is not high. Utility Model Content

[0006] Preferably, the base is manufactured by casting, the interior is hollowed out, and reinforcing ribs are evenly distributed on the hollowed part.

[0007] Preferably, the support column has a height of at least 135 mm.

[0008] Preferably, the support column is finely ground to a height difference within 0.005 mm, and the surface is scraped with 20 scraping points per square millimeter.

[0009] Preferably, the support column is a cuboid or a cylinder, and is detachably connected to the base by bolts.

[0010] Preferably, the positioning column is higher than the supporting column.

[0011] Preferably, the support column, positioning column and L-shaped locking block are made of carbon structural steel.

[0012] The principle of this utility model: In order to solve the problems of unstable precision, low efficiency, poor position stability, complicated alignment, repeated tool setting and high labor intensity of operators in the existing fixture parts of the turret box, the utility model adopts the following technical solutions: at least 3 support columns are detachably connected to the base, the surface of the support columns is finely ground, the consistency is good, and the 3 support columns are not collinearly distributed. The support columns are used to support the end face of the turret box after fine milling. As a process reference, it is no longer necessary to align through a dial indicator.
