figure 3 is the milling machine fixture's structure split sketch map.
In the figure: 1. a positioning unit; 2. a fixed seat; 3. a locking unit; 4. a workpiece; 5. and operating the window.
Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Example 1
As shown in fig. 1 to 3, a milling machine jig includes: a positioning unit 1 mounted on the fixed base 2; the locking unit 3 is arranged inside the lower end of the workpiece 4, and the locking unit 3 is arranged inside the lower end of the workpiece 4 and is in locking fit with the positioning unit 1 entering the inside of the lower end of the workpiece 4.
Here, the fixed seat 2 is a milling machine table; the workpiece 4 to be machined is a machine tool table blank.
The positioning method comprises the following steps: placing the workpiece 4 on a milling machine workbench, wherein the positioning unit 1 enters the lower end of the workpiece 4 in the process; then, the locking unit 3 is matched with the positioning unit 1 in a locking mode, and the workpiece 4 is clamped and positioned.
After the positioning is completed, the upper end face of the workpiece 4 and each side face of the workpiece 4 can be milled by a milling cutter, wherein each side face of the workpiece 4 refers to a front side face, a rear side face, a left side face and a right side face of the workpiece 4. In the embodiment, the workpiece 4 is positioned and clamped from the inside, so that the milling of each side surface of the workpiece 4 can be completed only by once positioning. The embodiment greatly reduces the conversion times of the positioning reference, thereby improving the processing precision of the milling machine on the workpiece 4.
Example 2
As shown in fig. 1 to 3, a milling machine fixture has a structure substantially the same as that of embodiment 1, and further, an operation window 5 is additionally provided on a side surface of the workpiece 4, and the locking unit 3 is exposed in the operation window 5, so that a worker can conveniently operate the locking unit 3.
