It solves the problem that existing fixtures are inconvenient for simultaneous positioning along the X and Y axes, requiring manual adjustment of the tool position to align with the workpiece, which affects processing quality and reduces processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling machine positioning fixture for processing zinc alloy buttons, comprising a support plate, longitudinal moving rods slidably connected to the front and rear sides of the bottom of the support plate, and transverse moving rods slidably connected to the left and right sides of the bottom of the support plate.

[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] like Figures 1 to 4As shown, this utility model provides a milling machine positioning fixture for processing zinc alloy buttons, including a support plate 1. Longitudinal moving rods 2 are slidably connected to the front and rear sides of the bottom of the support plate 1, and transverse moving rods 3 are slidably connected to the left and right sides of the bottom of the support plate 1. L-shaped rods 4 extending to the top of the support plate 1 are fixedly connected to the top of both the longitudinal moving rods 2 and the transverse moving rods 3, and the inner ends of each L-shaped rod 4 are fixedly connected to mutually fitting arc-shaped clamps 5. A first screw block 6 is fixedly connected to the bottom of the inner end of the longitudinal moving rod 2, and a first screw rod 7 is threadedly connected to the interior of each of the two first screw blocks 6. First brackets 8 are fixedly connected to the front and rear sides of the bottom of the support plate 1. The outer end of the first screw rod 7 is rotatably connected to the inner side of the first bracket 8, and a worm gear 9 is fixedly connected to the inner end of the first screw rod 7. A second screw block 10 is fixedly connected to the bottom of the inner end of the transverse moving rod 3. Both second screw blocks 10 are internally threaded with second screws 11. The left and right sides of the bottom of the bearing plate 1 are fixedly connected with second brackets 12. The left end of the second screw 11 on the left side is rotatably connected to the inner side of the second bracket 12, and the right end of the second screw 11 on the right side extends to the outer side of the second bracket 12 and is equipped with a forward and reverse motor 13. The top of the forward and reverse motor 13 is fixedly connected to the bottom of the bearing plate 1. The inner end of the second screw 11 is fixedly connected with a worm gear 14. The surface of the worm gear 14 meshes with the surface of the worm wheel 9. The two first screws 7 and the second screw 11 are arranged in opposite directions. The bottom of the bearing plate 1 is fixedly connected with a protective shell sleeved on the surface of the first screws 7 and the second screw 11 by bolts to protect the components at the bottom of the bearing plate 1 and prevent metal chips from falling and adhering to the surface of the parts during milling machine operation, thus affecting their use.

[0022] refer to Figure 1 The top of the support plate 1 is fixedly connected to a placement plate 15 located below the arc-shaped clamp 5, and the top of the placement plate 15 is fixedly connected to a smooth wear-resistant layer 16.

[0023] As a technical optimization of this utility model, by setting up a placement plate 15 and a smooth wear-resistant layer 16 in combination, a special placement area is provided for the workpiece, which is convenient for the operator to place the workpiece for positioning operation. At the same time, the smooth wear-resistant layer 16 on the top of the placement plate 15 can reduce the friction between the workpiece and the placement plate 15, prevent the workpiece surface from being scratched, and ensure the surface quality of the workpiece.

[0024] refer to Figure 1 The top of the L-shaped rod 4 is provided with a square groove 17, and the top of the bearing plate 1 is rotatably connected with guide posts 18. The surface of the guide posts 18 is in contact with one side of the inner wall of the square groove 17.

[0025] As a technical optimization of this utility model, by setting the square groove 17 and the guide column 18 in combination, when the longitudinal moving rod 2 and the transverse moving rod 3 drive the L-shaped rod 4 to move, the guide column 18 can provide guidance, making the movement of the L-shaped rod 4 more stable and accurate, and further improving the positioning accuracy of the arc clamp 5 for the workpiece.

[0026] refer to Figure 3 The top of both the longitudinal moving rod 2 and the transverse moving rod 3 are fixedly connected with T-shaped bars 19. T-shaped grooves 20 that cooperate with the T-shaped bars 19 are opened around the bottom of the bearing plate 1. The surface of the T-shaped bars 19 is slidably connected to the inner wall of the T-shaped grooves 20.

[0027] As a technical optimization of this utility model, by setting the T-shaped bar 19 and the T-shaped groove 20 in cooperation, when the longitudinal moving rod 2 and the transverse moving rod 3 move, the T-shaped bar 19 slides inside the T-shaped groove 20, so that the longitudinal moving rod 2 and the transverse moving rod 3 can slide smoothly on the bottom of the bearing plate 1, and prevent them from shifting or falling off during the movement, thereby enhancing the stability of the clamp structure.

[0028] refer to Figure 1 An anti-slip pad 21 is fixedly connected to the inner side of the arc-shaped clip 5, and the surface of the anti-slip pad 21 is provided with anti-slip texture.

[0029] As a technical optimization of this utility model, by setting the anti-slip pad 21, the friction between the arc-shaped clamp 5 and the workpiece surface can be increased. When the clamp is used to position and hold the workpiece, it can effectively prevent the workpiece from sliding or shaking during the processing, thus ensuring the accuracy and quality of the processing.

[0030] refer to Figure 2 The output end of the forward and reverse motor 13 is fixedly connected to a reducer 22, and the output end of the reducer 22 is fixedly connected to the right end of the second screw 11.

[0031] As a technical optimization of this utility model, by setting a reducer 22, the speed of the motor can be adjusted, making the rotation of the second screw 11 more stable and precise. At the same time, the reducer 22 can also increase the output torque, ensuring that there is sufficient force to achieve reliable positioning and clamping of the workpiece by the arc clamp 5 when driving the screw transmission and when linked through the worm gear 9 and worm 14.

[0032] The working principle and usage process of this utility model are as follows: During use, the fixture is installed on the milling machine's worktable, ensuring a secure installation. The protective shell is checked for proper installation to protect the components at the bottom of the support plate 1 and prevent metal debris from adhering and affecting use. The forward and reverse motors 13 and reducer 22 are checked for normal operation, and the connections of each component are verified to be secure. The workpiece is placed on the placement plate 15 on top of the support plate 1. Then, the forward and reverse motor 13 is started to drive the second screw 11 to rotate. The rotation of the second screw 11 drives the worm gear 14 to rotate. Through the transmission of the worm gear 14 and worm wheel 9, the first screw 7 rotates accordingly, causing the first screw 7 and the second screw 11 to rotate simultaneously. When the first screw 7 and the second screw 11 rotate, the first screw block 6 and the second screw block 10 move synchronously, thereby driving the longitudinal moving rod 2 and the transverse moving rod 3 to move in the front-back and left-right directions respectively. This synchronously drives the various arc-shaped clamps 5 to move and fix the workpiece. This achieves the effect of simultaneously pushing the workpiece around its perimeter while clamping it, automatically positioning the workpiece's XY axes without the need for tool setting, thus improving processing quality and efficiency.
