[0002] When a curtain support is produced and processed, a machine tool processing device is required to process it. The machine tool processing device is equipped with a positioning structure. At the same time, when the support is processed, it can be directly sleeved on the positioning structure, so that the sleeved curtain support can be stably processed.

[0003] When the existing machine tool processing positioning structure is in use, the curtain support is directly sleeved on the shaft frame of the structure and is fixedly connected to the movable seat through a four-lobe disc. However, after the support is sleeved on the shaft frame, the outer processing component processes the support. The force during processing may cause the support to shake on the shaft frame. After long-term processing, the support cannot be stably sleeved on the shaft frame. Therefore, an auxiliary limiting positioning structure needs to be proposed to prevent the support from shaking on the shaft frame. Summary of the Utility Model

The vertical plate moves through the slider. When the slider moves into the groove, the slider drives the vertical plate to move downward through the movable plate, so that the workpiece enters the inner side of the vertical plate. Then the vertical plate moves back to its original position through the movable block and pushes the vertical plate, so that the moved vertical plate limits the workpiece sleeved with the axle bracket, thereby further stabilizing the connection between the workpiece and the axle bracket and preventing the support workpiece from shaking on the axle bracket after long-term use.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0029] Please refer to Figures 1 - 3 As shown, this embodiment is a machining positioning structure for workpieces with shaft holes, including:

[0030] Positioning assembly, the positioning assembly includes a movable seat 12 and a four-lobe disk 13, and the four-lobe disk 13 is located on the surface of the outer end of the movable seat 12;

[0031] The movable seat 12 is used for connecting the four-lobe disk 13, and the four-lobe disk 13 is used for connecting the shaft bracket 14.

[0032] The positioning assembly further includes a fixed seat 11 and a shaft bracket 14. The fixed seat 11 is fixed at a specified position of the machine tool processing. The fixed seat 11 is movably connected to the movable seat 12, and the shaft bracket 14 is fixed on the surface of the outer end of the four-lobe disk 13;

[0033] The fixed seat 11 is used for connecting and rotating the movable seat 12, and the shaft bracket 14 is used for sleeving the supported workpiece.

[0034] Limit assembly, the limit assembly includes a support plate 21, a card slot 22, a groove 23, a movable block 24, a slider 25 and a vertical plate 26. The support plate 21 is fixed at the bottom end of the outer side of the movable seat 12. The card slot 22 is opened on the top surface of the support plate 21. The groove 23 is opened at the center of both sides of the card slot 22. The movable block 24 is located above the inside of the groove 23. The slider 25 is slidably connected between the inside of the card slot 22 and the inner side of the movable block 24. The vertical plate 26 is fixed at the top end of the slider 25;

[0035] The support plate 21 is used for opening the card slot 22 and connecting the slider 25. The card slot 22 is used for connecting and moving the slider 25. The groove 23 is used for connecting and moving the movable block 24. The movable block 24 is used for connecting the slider 25. The slider 25 is used for connecting the vertical plate 26. The vertical plate 26 is used for limiting the supported workpiece after sleeving.

[0036] Chute 27 is opened on both sides of the inside of the card slot 22 and the movable block 24. The chute 27 is slidably connected to the slider 25. A spring 241 is fixedly connected between the bottom end of the movable block 24 and the bottom end of the inside of the groove 23;

[0037] The opening of the chute 27 is for the slider 25 to slide between the card slot 22 and the movable block 24, so that the slider 25 drives the vertical plate 26 to move together. The spring 241 is used for connecting the movable block 24 and the inside of the groove 23, and at the same time for the movement of the movable block 24. When the slider 25 moves between the movable blocks 24, due to the inclined surface provided on the vertical plate 26, the supported workpiece presses the vertical plate 26 through the inclined surface, so that the movable block 24 enters the groove 23 through the spring 241, and the vertical plate 26 moves downward, so that the bottom end of the workpiece enters the inside of the vertical plate 26. [[ID=2,2]]

[0038] A support rod 211 is fixedly connected between the bottom end of the support plate 21 and the movable seat 12. Docking grooves 29 are opened on both sides of the top end of the support plate 21 and are located on both sides of the card slot 22. A short rod 28 is clamped inside each of the docking grooves 29. A baffle 291 is fixedly connected between the top ends of the short rods 28;

[0039] The vertical plate 26 is adsorbed to the baffle 291;

[0040] The support rod 211 provides auxiliary support for the support plate 21. The docking groove 29 is for the insertion of the short rod 28, and the two are plugged together, so that the baffle 291 is connected to the support plate 21. The baffle 291 has magnetism, so that the baffle 291 is adsorbed to the vertical plate 26, thereby limiting the moved vertical plate 26 by the baffle 291, and prompting the baffle 291 to limit the workpiece after sleeving through the vertical plate 26.

[0041] Working principle: Before the component is used, the slider 25 is located at the outer end of the card slot 22. When the component is used, hold the support workpiece by hand, align the workpiece with the shaft frame 14, and push the workpiece, so that the workpiece contacts the top of the vertical plate 26 during the movement on the shaft frame 14. The force during the movement of the workpiece pushes the vertical plate 26. At this time, the slider 25 moves towards the movable seat 12 in the card slot 22, so that the vertical plate 26 moves through the slider 25. When the slider 25 moves between the movable blocks 24, due to the inclined surface provided on the vertical plate 26, the support workpiece squeezes the vertical plate 26 through the inclined surface, and the squeezing force causes the spring 241 to contract in the groove 23, so that the movable block 24 enters the groove 23 through the spring 241, and the vertical plate 26 moves downward, so that the bottom end of the workpiece enters the inside of the vertical plate 26. Subsequently, the force squeezing the spring 241 disappears, and the spring 241 drives the movable block 24 and the slider 25 to pop out. The vertical plate 26 moves back to its original position through the movable block 24. Then push the vertical plate 26 by hand, and the vertical plate 26 moves towards the baffle 291 in the card slot 22 through the slider 25. Since the baffle 291 has magnetism, when the vertical plate 26 moves to contact the baffle 291, the baffle 291 is adsorbed to the vertical plate 26, thereby limiting the moved vertical plate 26 by the baffle 291, and prompting the adsorbed vertical plate 26 to limit the workpiece sleeved with the shaft frame 14, thereby further stabilizing the connection between the workpiece and the shaft frame 14; when the baffle 291 is replaced, directly pull out the baffle 291 by hand, and the pulling force drives the short rod 28 to leave the docking groove 29, so that the baffle 291 is separated from the support plate 21, which is convenient for replacing the baffle 291;

[0042] In the above steps, through the interaction between the card slot 22, the movable block 24 and the sliding groove 27, the slider 25 drives the vertical plate 26 to move.

[0043] Please refer to Figures 1 - 2 、 Figure 4 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes:

[0044] A shielding component;

[0045] The shielding component includes a fixed frame 31, a movable frame 32 and a moving plate 33. The fixed frame 31 is fixed to both sides of the outer end of the support plate 21. The movable frame 32 is clamped between the fixed frame 31 and the inner side of the support plate 21. The moving plate 33 is slidably connected to the inside of one end above the movable frame 32.

[0046] The fixed frame 31 is used for the connection of the movable frame 32. Both the movable frame 32 and the moving plate 33 are used to shield the card slot 22.

[0047] A movable shaft 34 is movably connected at the clamping joint of the movable frame 32 and the fixed frame 31. A magnetic plate 35 is fixedly connected to the bottom surface of the outer end of the support plate 21. The magnetic plate 35 is adsorbed to the outer side surface of the movable frame 32.

[0048] The movable shaft 34 is used for the movement of the movable frame 32 inside the fixed frame 31. The magnetic plate 35 is used to limit the position of the movable frame 32 when it is idle. The magnetic plate 35 is adsorbed to the outer side surface of the movable frame 32 through magnetic force, and can limit the position and store the movable frame 32 rotated to the lower part.

[0049] Working principle: Before the component is used, the movable frame 32 is located below the outer end of the support plate 21 and is adsorbed to the magnetic plate 35. When the vertical plate 26 limits the position of the socketed support workpiece, rotate the movable frame 32 by hand, so that the movable frame 32 rotates above the support plate 21 through the movable shaft 34. Then pull out the moving plate 33 by hand, so that the moving plate 33 is located above the card slot 22. When the processing part processes the socketed workpiece, the movable frame 32 and the moving plate 33 can shield the card slot 22 on the support plate 21 to prevent the debris during processing from falling into the card slot 22. When the component is not in use, rotate the movable frame 32 by hand, so that the movable frame 32 rotates below the support plate 21 through the movable shaft 34, and the magnetic plate 35 is adsorbed to the outer side surface of the movable frame 32 through magnetic force, and can limit the position and store the movable frame 32 rotated to the lower part.

[0050] The above steps can improve its own functionality.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
