[0032] Reference Figures 1 to 3, this embodiment discloses a new type of tooling fixture, including a base 1, the inner side of the base 1 is rotatably connected to a bidirectional threaded rod 2, one end of the bidirectional threaded rod 2 passes through the base 1 and is fixed with a handwheel 3, both ends of the outer side of the bidirectional threaded rod 2 are threadedly connected to a first sliding plate 4, the two first sliding plates 4 are slidably connected to the base 1, the inner sides of both sides of the two first sliding plates 4 are slidably connected to guide rods 5, the two guide rods 5 are fixed to the base 1, the inner sides of the top ends of the two first sliding plates 4 are fixed with bearings 6, the inner sides of the bearings 6 are fixed with connecting rollers 7, and the two connecting rollers 7 are fixed with clamping plates 8 at one end close to each other, and an angle adjustment mechanism is provided on one of the first sliding plates 4, which is used to adjust the angle of the two clamping plates 8, and a protective mechanism is provided on the angle adjustment mechanism.

[0033] The angle adjustment mechanism includes a worm gear 9, a worm 10 and a knob 11, wherein a worm gear 9 is fixed to one end of the outer side of one connecting roller 7, and a worm 10 is meshed and connected to the bottom of the worm gear 9. The worm 10 is rotatably connected to the first sliding plate 4, and a knob 11 is fixed to one end of the worm 10. Through the design of the angle adjustment mechanism, the fixture can flip the clamped workpiece according to actual machining requirements, thereby improving the machining efficiency of the parts.

[0034] Example 2

[0035] Based on the first embodiment, refer to Figures 3 to 6 , this embodiment further discloses a feasible solution for the protection mechanism in the new tooling fixture. In this embodiment, the protection mechanism includes a knob 11, a second sliding plate 12, a pressing plate 13, a protection plate 14, a placement slot 15 and a first spring 16. The knob 11 is fixed to one side of the first sliding plate 4 near one end of the worm gear 9. The inner side of the knob 11 is slidably connected to the second sliding plate 12. A pressing plate 13 is fixed to one side of the second sliding plate 12. The pressing plate 13 is slidably connected to the knob 11. A protection plate 14 is fixed to one end of the second sliding plate 12. The protection plate 14 is slidably connected to the knob 11. A placement slot 15 is provided on the inner side of the protection plate 14. The size of the placement slot 15 is the same as that of the knob 11. A first spring 16 is fixed to the other side of the second sliding plate 12. The first spring 16 is located on the inner side of the knob 11.

[0036] In addition, the protection mechanism also includes a first clamping block 17, a second clamping block 18, a lifting rod 19 and a second spring 20. The first clamping block 17 is fixed to one side of the second sliding plate 12. The first clamping block 17 is slidably connected to the knob 11. The second clamping block 18 is slidably connected to the inner side of one end of the knob 11. The second clamping block 18 is slidably connected to the knob 11. A lifting rod 19 is fixed to one end of the second clamping block 18. The lifting rod 19 is slidably connected to the knob 11. The second spring 20 is sleeved on the outer side of the lifting rod 19.

[0037] The design of the protection mechanism prevents the knob 11 from being accidentally touched, thereby ensuring that the angle of the angle adjustment mechanism is fixed.

[0038] A pointer 21 is fixed on one side of the connecting roller 7 away from one end of the worm gear 9, and a dial 22 is fixed on one side of the first sliding plate 4 close to one end of the pointer 21. The design of the pointer 21 and the dial 22 can better understand the flip angle of the clamped part.

[0039] A plurality of rectangular grooves are evenly distributed on one side of the clamping plate 8; the rectangular grooves can increase the contact area between the clamping plate 8 and the workpiece, thereby increasing the friction force.

[0040] The use process of the novel tooling fixture provided by the utility model is as follows: when a mechanical part needs to be clamped, the part to be processed is placed between the two first sliding plates 4, the handwheel 3 is fixedly connected to the bidirectional threaded rod 2, the bidirectional threaded rod 2 is threadedly connected to the first sliding plate 4, the first sliding plate 4 is slidably connected to the guide rod 5, and the handwheel 3 is turned. The rotation of the handwheel 3 drives the bidirectional threaded rod 2 to rotate, thereby causing the first sliding plate 4 to move along with it, and the two first sliding plates 4 approach each other, so that the clamping plate 8 clamps and fixes the mechanical part;

[0041] When the first clamping block 17 moves to the inner side of the knob 11, the second spring 20 pushes the second clamping block 18 to move and clamp the first clamping block 17;

[0042] The knob 11 is fixedly connected to the worm 10, which is meshed with the worm wheel 9. When the helix angle of the worm 10 is less than or equal to the friction angle, the connection between the worm 10 and the worm wheel 9 is self-locking. At this time, the worm 10 can only drive the worm wheel 9 to rotate, while the worm wheel 9 cannot drive the worm 10 to rotate. Due to the design of the worm wheel 9 and the worm 10, the component of the movement in the rotation direction will not drive the worm wheel 9 to rotate, thereby not affecting the accuracy of the rotation adjustment.

[0043] The worm wheel 9 is fixedly connected to the connecting roller 7, the bearing 6 is fixedly connected to the connecting roller 7, the connecting roller 7 is fixedly connected to the clamping plate 8, and the first sliding plate 4 is fixedly connected to the bearing 6. At this time, the knob 11 is turned, and the rotation of the knob 11 drives the worm 10 to rotate, thereby causing the rotation of the worm 10 to drive the worm wheel 9 to rotate, thereby causing the connecting roller 7 fixedly connected to the worm wheel 9 to rotate, thereby causing the clamping plate 8 connected to the connecting roller 7 to rotate, thereby causing the clamped mechanical parts to flip over. The design of the pointer 21 and the dial 22 can be used to understand the flip angle of the parts;

[0044] When the part is flipped over, in order to prevent the knob 11 from being accidentally touched, the lifting rod 19 is fixedly connected to the second clamping block 18, and the lifting rod 19 is pulled to one end. The movement of the lifting rod 19 drives the second clamping block 18 to move. At this time, the second clamping block 18 no longer clamps the first clamping block 17. At this time, the first spring 16 pushes the second sliding plate 12 to move, so that the protective plate 14 moves with it, so that the knob 11 is re-located to the inner side of the placement groove 15. The design of the protection mechanism prevents the knob 11 from being accidentally touched, thereby ensuring that the angle of the angle adjustment mechanism is fixed.

[0045] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
