[0032] Before the workpiece is milled by the machine tool, the workpiece is mounted on the clamping plate 4 through a plurality of clamping threaded holes 22 in cooperation with a clamp, and then the milling process can be carried out by the machine tool body 1. After the top of the workpiece is processed, the magnifying observation mirror 8 can be pulled so that the cross bar 3 drives the clamping plate 4 and the workpiece to flip over. At this time, the magnifying observation mirror 8 rises, and at the same time, the clamping plate 4 drives the workpiece to rotate and approach the magnifying observation mirror 8. At this time, the processing situation of the top of the workpiece can be observed through the magnifying observation mirror 8, thereby improving the operational versatility of the machine tool. During the workpiece processing, the driving motor 11 can be used to drive the driving screw 10 to rotate, so that the driving screw 10 drives the clamping table 2 to move horizontally and switch between the two operations of milling and grinding, so that the processing work can be carried out stably.

[0033] Example 2

[0034] Embodiment 2 is based on Embodiment 1, so that the clamping plate 4 can drive the workpiece to flip during the upward movement of the magnifying glass 8, such as Figure 1-2 and Figure 4As shown, a transmission rod 9 is rotatably penetrated on the back side of the support block 6, and a transmission flipping mechanism for supporting the flipping of the clamping plate 4 is provided between the transmission rod 9 and the cross bar 3. The transmission flipping mechanism includes two first bevel gears 12, and the two first bevel gears 12 are fixedly arranged at both ends of the transmission rod 9. A rotating rod 13 is rotatably provided inside the support block 6. The rod walls of the rotating rod 13 and the cross bar 3 are fixedly sleeved with a second bevel gear 14. The two adjacent first bevel gears 12 and the second bevel gear 14 are matched. A rotating groove matching the first bevel gear 12 and the second bevel gear 14 is provided on the side of the clamping plate 4. The cross bar 3 passes through the rotating groove.

A sliding hole is provided inside the rack 15, and a sliding rod 17 is slidably penetrated in the sliding hole. The sliding rod 17 is fixedly arranged inside the support block 6, and the rod wall of the sliding rod 17 is fixedly sleeved with two symmetrically arranged baffles 18, and the two baffles 18 are arranged on both sides of the rack 15.

[0035] When the magnifying observation mirror 8 moves upward, the vertical rod 7 drives the rack 15 to rotate. At this time, under the sliding cooperation of the sliding rod 17 and the sliding hole, the rack 15 can stably move longitudinally and push the circular gear 16 to rotate. When the circular gear 16 drives the rotating rod 13 to rotate, through the meshing of two sets of adjacent first bevel gears 12 and second bevel gears 14, and the transmission of the transmission rod 9, the cross bar 3 can rotate synchronously and drive the clamping plate 4 and the workpiece to flip, so that the magnifying observation mirror 8 can observe the top processing condition of the workpiece.

[0036] Example 3

[0037] Embodiment 3 is based on Embodiment 2 in order to determine the position of the magnifying observation mirror 8 after the height of the magnifying observation mirror 8 is adjusted and the clamping plate 4 is turned over, as shown in FIG. Figure 2-3 As shown, an adjustment and positioning mechanism is provided at the upper end of the rod wall of the vertical rod 7, and the adjustment and positioning mechanism includes a positioning rod 19. A connecting frame 20 is fixedly provided at the upper end of the outer wall of the vertical rod 7.

A pulling hole is provided at the end of the positioning rod 19, and a plurality of positioning grooves for matching the positioning rod 19 are provided on the outer wall of the support block 6. A spring 21 is provided on the rod wall of the positioning rod 19, and the two ends of the spring 21 are respectively fixedly connected to the connecting frame 20 and the positioning rod 19.

[0038] Before stretching the magnifying observation glass 8, the positioning rod 19 is pulled out from the positioning groove through the pulling hole. At this time, the spring 21 is squeezed, and when the magnifying observation glass 8 moves up, the vertical rod 7 drives the connecting frame 20 to move. When the clamping plate 4 is successfully flipped over, the positioning rod 19 is released. Under the elastic force of the spring 21, the positioning rod 19 rebounds and is inserted into the positioning groove of the side wall of the support block 6 to determine the position of the clamping plate 4 and the observation magnifying glass 8.
