[0023] 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.

[0024] Example 1

[0025] like Figures 1 to 7 As shown, this is the first embodiment of the utility model, providing a CNC milling and shearing hybrid machine, including a frame 1, a shearing component 2 disposed in the inner cavity of the frame 1, a positioning component 3 disposed on the inner wall of the frame 1 located outside the shearing component 2, and a milling pin component 4 disposed on the inner wall of the frame 1 located below the positioning component 3.

[0026] Among them, the shearing assembly 2 includes a push cylinder 201, the outer side of the push cylinder 201 is connected to the inner wall of the frame 1, the outer side of the push cylinder 201 is connected to a movable frame 202, and the top of the movable frame 202 is provided with pneumatic shears 203 located on both sides of the movable frame 202.

[0027] The positioning component 3 includes a mounting frame 301, a pneumatic cylinder 302 is provided on the top of the mounting frame 301, a drive motor 305 is provided on the top of the pneumatic cylinder 302, the drive motor 305 drives and connects to a movable plate 303, a pressure block 304 is provided at the bottom of the movable plate 303, and a positioning carrier 306 located outside the pneumatic scissors 203 is provided on the top of the mounting frame 301.

[0028] The product is moved from the top of the frame 1 to the top of the positioning carrier 306 by the picking mechanism. At the same time, the pneumatic cylinder 302 and the drive motor 305 are activated to drive the movable plate 303 and the pressure block 304 to rise and rotate, thereby removing the obstruction of the positioning carrier 306 by the movable plate 303 and preventing the picking mechanism from being hindered in adsorbing the product as it descends. The product is then clamped on the top of the positioning carrier 306. At this time, the pneumatic cylinder 201 is activated to drive the movable frame 202 and the pneumatic shears 203 to move. The pneumatic shears 203 cuts the sprue at the bottom of the product. Then, the reset pneumatic cylinder 302 and the drive motor 305 drive the pressure block 304 to clamp the product on the positioning carrier 306. Finally, the milling pin assembly 4 mills the product, thus completing the shearing and milling of the product. The shearing and milling are carried out in the same processing area, which reduces the need for multiple operation steps and improves processing efficiency.

[0029] Example 2

[0030] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the milling pin assembly 4 includes a slide rail 401. The top of the slide rail 401 is connected to the inner wall of the frame 1. The inner wall of the frame 1 is provided with a front-to-back moving structure 403 located outside the slide rail 401. The front-to-back moving structure 403 is driven to connect a connecting frame 402 that is adjusted outside the slide rail 401.

[0031] The activation of the forward and backward moving structure 403 drives the connecting frame 402 to move on the outer surface of the slide rail 401. The slide rail 401 limits the movement of the frame to prevent positional deviation and thus prevent it from affecting the running accuracy.

[0032] Among them, the bottom of the connecting frame 402 is provided with a left and right moving structure 404, the left and right moving structure 404 is driven to connect to a vertical moving structure 405, the outside of the vertical moving structure 405 is connected to a spindle motor 406, and the spindle motor 406 is driven to connect to a milling cutter 407 located below the positioning carrier 306.

[0033] By activating the left-right moving structure 404, the up-down moving structure 405 is driven to move left and right on the outside of the connecting frame 402, so that the milling cutter 407 is adjusted to a suitable position for milling the product. At the same time, when the milling cutter 407 moves to the suitable position, the spindle motor 406 is activated to drive the milling cutter 407 to move upward, and the milling cutter 407 performs milling operations on the product that is limited between the positioning carrier 306 and the pressure block 304.

[0034] Among them, there are two positioning carriers 306, and the external dimensions of the two positioning carriers 306 are adapted to the internal dimensions of the product.

[0035] When the material handling mechanism puts the freshly injection-molded product into the milling and shearing mixer, the product is limited by two positioning carriers 306 and clamped and fixed by pressure blocks 304 to prevent it from moving during milling and thus avoid affecting the milling quality.

[0036] Among them, four pneumatic scissors 203 are provided, and the four pneumatic scissors 203 are arranged in pairs on the outside of the positioning carrier 306.

[0037] Four pneumatic shears 203 are used to cut the sprue at the bottom of the product. Since there are two connection points between the bottom of the product and the sprue, the four pneumatic shears 203 cut two products at a time, thus allowing two products to be cut simultaneously and improving processing efficiency.

[0038] Among them, the bottom of the frame 1 is equipped with pulleys, and the bottom of the outer side of the frame 1 is equipped with a support;

[0039] The pulley system facilitates easy movement of the milling and shearing mixer by operators, allowing it to be moved to a suitable location. The support frame secures the entire mixer to the ground, preventing any displacement.

[0040] Working principle and usage process of this utility model:

[0041] First, after the product is produced from the injection molding machine, the picking mechanism moves the product from the injection molding machine to the milling and shearing mixer. The picking mechanism then picks up the product and moves it to the top of the two positioning carriers 306. At this point, the pneumatic cylinder 302 and drive motor 305 are activated, causing the movable plate 303 and pressure block 304 to move and rotate upwards, ensuring they do not interfere with the picking mechanism placing the product on top of the positioning carriers 306. Simultaneously, the positioning carriers 306 and the picking mechanism limit the product's position. Then, the push cylinder 201 is activated, moving the movable frame 202 and pneumatic shears 203 forward to cut the sprue at the bottom of the product, thereby... After the sprue is cut off, the material handling mechanism releases its suction. The pressure block 304 then presses and fixes the product to prevent positional displacement, thanks to the reset of the pneumatic cylinder 302 and drive motor 305. The operation of the forward and backward moving structure 403, the left and right moving structure 404, the up and down moving structure 405, and the spindle motor 406 drives the milling cutter 407 to move to the bottom of the product. The milling cutter 407 then performs milling operations on the product, making it easier for operators to process the product without requiring multiple processing steps. This reduces the area occupied by the equipment, improves processing efficiency, and brings convenience to the operators.
