[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-6 As shown, this utility model provides an adjustable-angle tooling fixture for metal product processing, including a base 1 for fixed support. A support frame 11 is fixedly mounted on the top of the base 1. A rotating shaft 2 is rotatably mounted inside the support frame 11. The rotation of the rotating shaft 2 drives the positioning assembly 4 to rotate. A mounting plate 21 is fixedly mounted on the outside of the rotating shaft 2. The positioning assembly 4 is mounted on the outside of the mounting plate 21. The positioning assembly 4 is electrically driven to rotate a bidirectional threaded rod. The bidirectional threaded rod drives two clamping plates 42 to move in opposite directions, thereby completing the clamping of the metal workpiece. A pointer 22 is mounted on the bottom of the mounting plate 21, and a scale strip 23 is mounted on the outside of the support frame 11. The pointer 22 works in conjunction with the scale bar 23 to more accurately adjust the angle of the workpiece. A transmission rod 3 is rotatably mounted on the outer side of the base 1, and a worm gear 31 is fixedly mounted on the outer side of the transmission rod 3. A rotating rod 32 is rotatably mounted on the end of the support frame 11 away from the positioning component 4. The rotation of the worm gear 31 drives the meshing worm wheel 33 to rotate. The bottom end of the rotating rod 32 is fixedly mounted with the worm wheel 33, and the worm gear 31 and the worm wheel 33 mesh with each other. A circular gear 34 is fixedly mounted on the top end of the rotating rod 32, and a crown gear 35 is fixedly mounted on the outer side of the rotating shaft 2. The circular gear 34 and the crown gear 35 mesh with each other, and the rotation of the circular gear 34 drives the crown gear 35 to rotate.

[0022] The positioning component 4 includes a movable frame 41, of which there are two. A clamping plate 42 is installed on the outside of the movable frame 41. The movable frame 41 has symmetrically distributed slots 43. A T-shaped plug 44 is fixed on the outside of the clamping plate 42. The T-shaped plug 44 is damped and inserted into the slot 43. Under no external force, the T-shaped plug 44 will not disengage from the slot 43.

[0023] By adopting the above technical solution, the T-shaped insert 44 is inserted into the slot 43, which facilitates the installation of the clamping plate 42. This allows the type of clamping plate 42 to be changed according to the needs of the metal workpiece, thereby improving the stability of clamping and positioning.

[0024] The base 1 has symmetrically distributed mounting brackets 12 fixed on both sides of its bottom end, and mounting holes 13 are provided in the mounting brackets 12.

[0025] By adopting the above technical solution, the mounting bracket 12 and the mounting hole 13 can be used to easily install the entire device.

[0026] Mounting plate 21 can be detachably mounted on the outside of rotating shaft 2.

[0027] By adopting the above technical solution, the mounting plate 21 can be installed and removed.

[0028] A turntable 36 is rotatably mounted on the outer side of the base 1, and the end of the turntable 36 is fixedly connected to the transmission rod 3.

[0029] By adopting the above technical solution, the turntable 36 rotates, driving the transmission rod 3 to rotate.

[0030] The mounting plate 21 is fixed with symmetrically distributed guide rods 24 on the side near the support frame 11. The support frame 11 has an annular groove 25 on its outer side, and the guide rods 24 are movably inserted into the annular groove 25.

[0031] By adopting the above technical solution, the guide rod 24 and the annular groove 25 can assist the mounting plate 21 in angle adjustment.

[0032] Protective pads 45 are fixedly provided on the opposite side of the two clamping plates 42.

[0033] By adopting the above technical solution, the protective pad 45 can protect the metal workpiece.

[0034] The pointer 22 is detachably mounted on the bottom of the mounting plate 21.

[0035] By adopting the above technical solution, pointer 22 can be installed and removed.

[0036] Working principle: First, the metal workpiece to be processed is placed between two clamping plates 42. Then, the two clamping plates 42 are moved in opposite directions by electric drive to clamp the metal workpiece. When the angle of the metal workpiece needs to be adjusted, the turntable 36 is rotated. The rotation of the turntable 36 drives the transmission rod 3 to rotate, which in turn drives the worm gear 31 to rotate, which in turn drives the meshing worm wheel 33 to rotate. The rotation of the worm wheel 33 drives the rotating rod 32 to rotate, which in turn drives the circular gear 34 to rotate, which in turn drives the meshing crown gear 35 to rotate, which in turn drives the rotating shaft 2 to rotate, which in turn drives the mounting plate 21 to rotate. This allows the positioning component 4 and the metal workpiece to rotate. When adjusting the angle, the pointer 22 and the scale bar 23 can improve the accuracy of the angle adjustment of the metal workpiece, making the operation simpler. At the same time, the self-locking of the worm gear 31 and the worm wheel 33 can improve the stability of the metal workpiece.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
