Horizontal turning device for milling machine (2)

In particular, the present invention provides a horizontal turning device (2) that performs surface machining on a work table of a milling machine by means of horizontal turning, thereby achieving a significant increase in processing efficiency and an effective reduction in equipment cost.

According to the current popular mobile phone casing, most of the outer surface is an arc-shaped curved surface, and the arc-shaped curved surface processing method is mainly processed by a numerically controlled vertical milling machine; The numerically controlled vertical milling machine is mainly provided on the machine tool 10 with a table 11 for feeding in a first horizontal direction (X-axis direction) and a second horizontal direction (Y-axis direction), on the table 11 Then, the workpiece 13 is clamped and fixed by a positioning fixture 12, so that the workpiece 11 can drive the workpiece 13 to feed in the first horizontal direction (X-axis direction) and the second horizontal direction (Y-axis direction), and the machine tool 10 is vertical. A column 14 is arranged in the (Z-axis), and a spindle head 15 for vertical (Z-axis) lifting is mounted on the column 14 with a linear slide, and the spindle head 15 is provided with a machining tool. 16. Further, the machining tool 16 can perform vertical and downward (Z-axis) lifting displacement and high-speed rotation to perform milling work on the workpiece 13 on the table 11. When the workpiece 13 on the table 11 is subjected to arc-shaped surface processing, the workpiece 11 is used to drive the horizontal displacement of the workpiece 13 for different positions of feed cutting, and the spindle head 15 drives the processing tool 16 to move up and down for different depths. The cutting is performed, and the surface processing of the workpiece 13 is completed by numerically controlling the milling. However, in the processing mode, since the workpiece 13 is subjected to the feed cutting for each track, the table 11 must drive the workpiece 13 to perform horizontal displacement of the full stroke, so the machining speed is very slow; and the milling method is also very large on the surface of the workpiece 13. It is easy to leave a knife mark, so that the milling is completed After that, it must be polished and polished to obtain the required roughness. Therefore, it takes about one hour for a mobile phone case to complete the required surface processing, which results in inefficient processing.

Referring to Fig. 2, if a tool holder 17 for vertical (Z-axis) lifting is added to one side of the column 14 of the vertical milling machine, a vertical position is set on the table 11 of the milling machine. The rotating table 18 is for clamping and driving the workpiece 13 to rotate, and the workpiece 13 on the rotary table 18 can be surface-formed by vertical turning. The vertical turning method is performed by the workpiece 13 being rotated. The table 18 drives the rotation so that the rotary table 18 can simultaneously process the two opposite sides of the workpiece 13 for each rotation. Therefore, the table 11 only needs to drive the workpiece 13 to perform horizontal displacement of the half stroke, thereby increasing the processing speed and turning. It is also easy to obtain the required roughness; although it can improve the disadvantages of the milling method, the tool holder 17 must constantly move vertically (Z-axis) as the workpiece 13 rotates, and the vertical direction (Z-axis) rapid lifting action is not only easy to increase the cantilever effect of the machine due to the inertia of the gravity acceleration, and the inertia of the gravity acceleration is also likely to damage the motor during high acceleration and deceleration, and the ball of the linear slide of the tool holder 17 Easily into sliding contact resulting in deformation of the track scratches, and thus affect the machining accuracy, so that the vertical turning of the milling mode also has its drawbacks to be improved.
