Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-8, the present utility model provides a technical solution: a flip - type machining fixture for mechanical parts, including a placement seat 1 and support columns 2, with the periphery of the bottom surface of the placement seat 1 fixedly connected to the support columns 2; a support plate 3 is fixedly connected to one side surface of the placement seat 1, a driving motor 4 is fixedly connected to the top surface of the support plate 3, the output end of the driving motor 4 passes through one side surface of the placement seat 1 and is fixedly connected to a double - headed lead screw 5, the side surface of the double - headed lead screw 5 away from the driving motor 4 is rotatably connected to the placement seat 1, several thread sleeves 6 are sleeved on both sides of the surface of the double - headed lead screw 5, a connecting plate 7 is fixedly connected to the top surface of the thread sleeve 6, a rotating rod 8 is connected through one side surface near the top of the connecting plate 7, a clamping plate 13 is fixedly connected to one side surface of the rotating rod 8, and grooves 14 are symmetrically opened inside the clamping plate 13; further included: an extension component 15 is arranged inside the groove 14; wherein, the extension component 15 includes a connecting block 1501 fixedly connected to the groove 14, a sleeve 1502 is fixedly connected to the top surface of the connecting block 1501, and a fixed block 1503 is fixedly installed inside the sleeve 1502; wherein, a first spring 1504 is fixedly connected to the top surface of the fixed block 1503, a stabilizing block 1505 is fixedly connected to the top surface of the first spring 1504, as Figures 1-5 shown, by setting the extension component 15, it is possible to clamp and limit the unclamped two ends of parts with different lengths, thereby preventing the parts from detaching from the clamping plate due to their own gravity and inertia. Through the through - connection of the connecting plate 7 and the placement seat 1, and the cooperation between the connecting plate 7 and the placement seat 1, it is possible to limit the thread sleeve 6, thereby ensuring the movement of the thread sleeve 6 on the double - headed lead screw 5. At the same time, the first spring 1504 is a rubber composite spring in the prior art.

[0033] A telescopic rod 1506 is fixedly connected to the top surface of the stabilizing block 1505, a clamping plate 1507 is fixedly connected to the top surface of the telescopic rod 1506, the clamping plate 1507 is sleeved with the sleeve 1502, several limiting grooves 1508 are opened on one side inside the clamping plate 1507, a connecting groove 1509 is opened on one side surface of the stabilizing block 1505, several second springs 1510 are fixedly installed inside the connecting groove 1509, a fixing plate 1511 is fixedly connected to the side surface of the second spring 1510 away from the connecting groove 1509, a limiting ball 1512 is fixedly connected to the side surface of the fixing plate 1511 away from the second spring 1510, and the limiting ball 1512 is engaged with the limiting groove 1508, as Figure 4 , 5As shown in FIGS. 7, by pressing the clamping plate 1507, as the clamping plate 1507 descends due to the pressing, the telescopic rod 1506 can be driven to descend. At the same time, when the clamping plate 1507 descends, the limiting groove 1508 on the clamping plate 1507 will squeeze the limiting ball 1512, so that the limiting ball 1512 will squeeze the fixed plate 1511 and the second spring 1510, causing the limiting ball 1512 to separate from the limiting groove 1508. At the same time, after the clamping plate 1507 descends to an appropriate position, when the limiting groove 1508 on the clamping plate 1507 and the limiting ball 1512 are in a horizontal line, due to the characteristics of the second spring 1510, the limiting ball 1512 will be squeezed, causing the limiting ball 1512 to engage with the limiting groove 1508 again, so that the clamping plate 1507 can be limited, and the unclamped ends of parts of different lengths can be clamped and limited, preventing the parts from detaching from the clamping plate 13 due to their own gravity and inertia. At the same time, the second spring 1510 is a rubber composite spring in the prior art, and the rubber composite spring has a large elastic force, making the engagement between the limiting ball 1512 and the limiting groove 1508 tighter. At the same time, due to the self-gravity of the parts, the limiting ball 1512 will not separate from the limiting groove 1508.

[0034] On the other side surface of the rotating rod 8, a first pulley 9 is connected through it. The surface of the first pulley 9 is adhesively connected with a belt 10. The bottom surface of the belt 10 is adhesively connected with a second pulley 11. In the middle of the second pulley 11, a rotating rod 12 is connected through it. One side surface of the rotating rod 12 is rotatably connected with the connecting plate 7. On the side surface of the rotating rod 12 far from the second pulley 11, an extension plate 16 is connected through it. On both sides of the extension plate 16, a clamping rod 17 is connected through it. A third spring 18 is sleeved on the side surface of the clamping rod 17 far from the extension plate 16, as Figure 2 shown. By rotating the rotating rod 12, the rotating rod 12 can drive the rotation of the second pulley 11. By the rotation of the second pulley 11, the rotation of the belt 10 can be driven. By the rotation of the belt 10, the rotation of the first pulley 9 can be driven. By the rotation of the first pulley 9, the rotation of the clamping plate 13 can be driven, so that the parts clamped by the clamping plate 13 can be turned over.

[0035] On one side surface of the third spring 18, a fitting plate 19 is fixedly connected. On the other side surface of the third spring 18, it is fixedly connected with the extension plate 16. The fitting plate 19 is penetrated by the clamping rod 17. On the side surface of the fitting plate 19 far from the third spring 18, it is adhesively connected with the connecting plate 7. On both sides near the bottom of the connecting plate 7, clamping grooves 20 are symmetrically opened, and the clamping grooves 20 are engaged with the clamping rods 17, as Figure 6 、 8As shown, the third spring 18 is a rubber composite spring in the prior art. The rubber composite spring has a relatively large elastic force, making the engagement between the clamping rod 17 and the clamping groove 20 tighter. At the same time, it can also limit the rotation rod 12. At the same time, the clamping grooves 20 are distributed and opened with the rotation rod 12 as the center point, and the number of clamping grooves 20 is not less than 4.

[0036] Working principle: Before using this kind of reversible mechanical part processing tooling, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 8 As shown, first, by setting the extension component 15, according to the length of the part, the clamping plate 1507 is pressed. When the clamping plate 1507 is pressed and descends, it drives the telescopic rod 1506 to descend. At the same time, when the clamping plate 1507 descends, the limiting groove 1508 on the clamping plate 1507 squeezes the limiting ball 1512, so that the limiting ball 1512 squeezes the fixed plate 1511 and the second spring 1510, so that the limiting ball 1512 is separated from the limiting groove 1508. At the same time, after the clamping plate 1507 descends to a suitable position, when the limiting groove 1508 on the clamping plate 1507 and the limiting ball 1512 are in a horizontal line, due to the characteristics of the second spring 1510, the limiting ball 1512 is squeezed, so that the limiting ball 1512 is re-engaged with the limiting groove 1508, so that the clamping plate 1507 can be limited, so that the unclamped ends of parts of different lengths can be clamped and limited, so as to prevent the parts from detaching from the clamping plate 13 due to their own gravity and inertia.

[0037] Secondly, by setting the extension plate 16, the clamping rod 17, the third spring 18, the fitting plate 19 and the clamping groove 20, by pulling the clamping rod 17, after the clamping rod 17 is separated from the clamping groove 20, by rotating the rotating rod 12, the rotating rod 12 can drive the rotation of the second pulley 11. The rotation of the second pulley 11 can drive the rotation of the belt 10. The rotation of the belt 10 can drive the rotation of the first pulley 9. The rotation of the first pulley 9 can drive the rotation of the clamping plate 13, so that the parts clamped by the clamping plate 13 can be turned. At the same time, after the clamping plate 13 is turned, by loosening the clamping rod 17, the clamping rod 17 returns to its original position under the action of the third spring 18, so that the clamping rod 17 is re-engaged with the clamping groove 20, thus completing the limitation of the rotating rod 12.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
