The radial arm can be raised, lowered, and rotated, and the milling head can be adjusted at multiple angles to realize vertical and horizontal milling composite machining. However, most of the existing radial milling machine workpiece fixing fixtures adopt an integral design. When the clamping parts need to be replaced and maintained, the operator cannot accurately replace only the damaged parts. The entire fixture assembly needs to be disassembled for replacement.

[0003] To address the aforementioned issues, this application proposes a workpiece fixing fixture for a radial milling machine. Utility Model Content

[0048] Working principle:

[0049] The workpiece to be machined by the milling machine body 1 is placed on the top support table 4. The output end of the cylinder 18 drives the side limit frame 17 to adjust its position, thereby restricting the position of one side of the workpiece. The bottom limit rod 5 of the mounting plate 3 cooperates with the limit hole 6 to restrict the position of the mounting plate 3 and the top support table 4 on the worktable 2. The mounting plate 3 is installed and fixed on the top of the worktable 2 by the threaded installation between the fixing bolt 8 and the threaded hole 7. The rotating screw block 26 is rotated and adjusted by the tool. When the rotating screw block 26 rotates, it drives the worm gear 25 to rotate in the side fixed box 19. When the worm gear 25 rotates, it drives the meshing worm wheel 24 to rotate. The worm wheel 24 drives the inner adjusting screw 20 to rotate and adjust. When the adjusting screw 20 rotates, it drives the outer inner moving slide plate 21 to slide in the top support table 4. The inner moving slide plate 21 drives the inner adjusting slant groove 22 to move synchronously. The inner moving slide plate 21 passes through The adjusting sloping groove 22 pushes the adjusting slide rod 23, which in turn drives the moving slider 15 to slide within the top support table 4. The moving slider 15 slides to a limit outside the limiting slide rod 16, which in turn drives the top sliding seat 9 to move and adjust. The top sliding seat 9 then drives the outer mounting sleeve 10 and the inner clamping plate 14 to move. The inner clamping plate 14 clamps and fixes the workpiece. When the inner clamping plate 14 needs to be replaced, the fixing nut 13 on the outside of the fixing screw 11 is removed by rotating it upwards. The outer mounting sleeve 10 and the inner clamping plate 14 are then removed from the top sliding seat 9. The inner clamping plate 14 is replaced with one suitable for the current workpiece type. The side fixing hole plate 12 is then installed to a limit outside the fixing screw 11, and the fixing nut 13 is threaded on the outside of the fixing screw 11. The installation positions of the outer mounting sleeve 10 and the inner clamping plate 14 are fixed, and the workpiece is stably clamped. The workpiece is then processed by the milling machine body 1.

[0050] The milling machine body 1 includes a bed, a rocker arm that can rotate around a column, a column that vertically supports the rocker arm, a milling head containing a spindle and a speed change mechanism, a movable table, and a transmission and control system.
