The double-head design can not only complete multiple processing processes in the same working step, but also ensure the accuracy and consistency of each operation. It is particularly suitable for processing workpieces that require high precision and complex structures, such as automotive parts, aerospace parts, and industrial mold manufacturing.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a double-head locking milling machine device, including a body 1, a support frame 2 is fixedly connected to one side of the body 1, a cylinder 3 is fixedly connected to one side of the support frame 2, a conical column 4 is fixedly connected to the output end of the cylinder 3, a fixed frame 5 is fixedly connected to the other side of the support frame 2, the conical column 4 is slidably connected to the inside of the fixed frame 5, a slider 6 is slidably connected to the inside of the fixed frame 5, a limiting block 7 is fixedly connected to one side of the slider 6, the limiting block 7 contacts the conical column 4, a clamping block 8 is fixedly connected to one side of the limiting block 7, a fixing plate 9 is fixedly connected to the outer wall of the fixing frame 5, a supporting column 10 is fixedly connected to one side of the fixing plate 9, the slider 6 is slidably connected to the outer wall of the supporting column 10, a spring 11 is sleeved on the outer wall of the supporting column 10, one end of the spring 11 is fixedly connected to one side of the fixing plate 9, and the other end of the spring 11 is fixedly connected to one side of the slider 6, a sliding component is arranged on the top of the body 1, and the sliding component is used for the moving function.

[0033] Specifically, when using the milling machine device, first insert the workpiece to be processed into the outer wall of the clamping block 8. Then, the output end of the cylinder 3 drives the conical column 4 to slide, and the conical column 4 moves under the force, thereby pushing the limit block 7 to displace. After the limit block 7 is forced, it drives the connected slider 6 to slide inside the fixed frame 5. At the same time, the limit block 7 is also moved through the clamping block 8 connected to one side. During the movement of the slider 6, the support column 10 connected to one side is squeezed to cause it to shrink. The movement of the clamping block 8 causes it to further expand and fix inside the workpiece, thereby effectively achieving a firm fixation of the workpiece.

[0034] Reference Figure 1 and Figure 2 The sliding assembly includes a slide rail 15 and a milling table 14. The slide rail 15 is fixedly connected to the top of the body 1. The two milling tables 14 are slidably connected to the outer wall of the slide rail 15. A first motor 12 is fixedly connected to one side of the body 1. A bidirectional screw 13 is fixedly connected to the output end of the first motor 12. The two milling tables 14 are both threadedly connected to the outer wall of the bidirectional screw 13.

[0035] Specifically, after the fixation is completed, the bidirectional screw 13 is driven to rotate by the output end of the first motor 12. Under the action of force, the bidirectional screw 13 drives two left-right symmetrical milling tables 14 connected to the outer wall to move relative to each other, so that the milling table 14 can be accurately moved to the outer position of the workpiece for processing operations, ensuring the accuracy and consistency of the processing process.

[0036] Reference Figure 1 and Figure 4 One side of the two milling tables 14 is fixedly connected to a connecting frame 16, a second motor 17 is fixedly connected inside the connecting frame 16, a crank 18 is fixedly connected to the output end of the second motor 17, a connecting column 19 is fixedly connected to one side of the crank 18, one end of the connecting column 19 is fixedly connected to a connecting frame 20, one end of the connecting frame 20 is fixedly connected to a third motor 21, a milling cutter 22 is fixedly connected to the output end of the third motor 21, a connecting ring 23 is fixedly connected to the outer wall of the connecting frame 20, a connecting rod 24 is fixedly connected to the outer wall of the connecting ring 23, a rotating ring 25 is fixedly connected to one side of the connecting rod 24, and the rotating ring 25 is rotatably connected to the inner wall of the connecting frame 16.

[0037] Specifically, when the angle of the milling cutter 22 needs to be adjusted, the crank 18 is driven to rotate through the output end of the second motor 17, and the crank 18 is forced to push the connecting column 19 connected to one side to rotate, and the connecting column 19 drives the connecting frame 20 connected to one side to rotate, and the connecting frame 20 is forced to push the connecting ring 23 connected to the outer wall to move, and the connecting ring 23 further drives the connecting rod 24 connected to one side to move. The movement of the connecting rod 24 causes the rotating ring 25 connected to one side to rotate inside the connecting frame 16. This process enables the connecting frame 20 to drive the third motor 21 and the milling cutter 22 connected to one end to make corresponding adjustments. After adjusting to the required position, the output end of the third motor 21 drives the milling cutter 22 to rotate, thereby starting to accurately process the workpiece, realizing the precise adjustment of the angle of the milling cutter 22, and ensuring the accuracy and efficiency of the processing process.

[0038] Working principle: When using the milling machine device, first insert the workpiece to be processed into the outer wall of the block 8, and then drive the conical column 4 to slide through the output end of the cylinder 3. The conical column 4 is forced to push the limit block 7 to move, and the limit block 7 is forced to drive the slider 6 connected on one side to slide inside the fixed frame 5. At the same time, the limit block 7 will also drive the block 8 connected on one side to move. When moving, the slider 6 will be forced to squeeze the support column 10 connected on one side to shrink it, and through the movement of the block 8, it is supported inside the workpiece to fix it, thereby achieving the effect of effectively fixing the workpiece. After the fixation is completed, the bidirectional screw 13 is driven to rotate through the output end of the first motor 12, and the bidirectional screw 13 is forced to drive the two left-right symmetrical milling tables 14 connected to the outer wall to move relatively, thereby moving the milling table 14 to the workpiece. The outer side is processed. When the angle of the milling cutter 22 needs to be adjusted, the crank 18 can be driven to rotate by the output end of the second motor 17. The crank 18 is forced to drive the connecting column 19 connected on one side to rotate, and the connecting column 19 is forced to drive the connecting frame 20 connected on one side to rotate. The connecting frame 20 is forced to drive the connecting ring 23 connected to the outer wall to move, and the connecting ring 23 is forced to drive the connecting rod 24 connected on one side to move. The connecting rod 24 is forced to drive the rotating ring 25 connected on one side to rotate inside the connecting frame 16, so that the connecting frame 20 drives the third motor 21 and the milling cutter 22 connected at one end to move. After adjusting to the required position, the milling cutter 22 is driven to rotate by the output end of the third motor 21, and then the workpiece is processed, thereby achieving the effect of adjusting the angle of the milling cutter 22.
