The moving mechanism 5 drives the collecting mechanism 7 to move in a direction perpendicular to the feeding direction of the milling head 3, and the lifting mechanism 6 drives the collecting mechanism 7 to move in a vertical direction. The collecting mechanism 7 comprises a positioning component 71 rotatably connected to the lifting mechanism 6 and a clamping component 72 connected to the positioning component 71. The positioning component 71 drives the clamping component 72 to rotate. The clamping component 72 is located below the milling head 3, and the clamping component 72 moves in a direction close to or away from the collecting box 4. The machine body 1, the fixture 2 and the milling head 3 are the basic facilities for realizing the processing of the spline shaft. After the user clamps the material at the milling head 3, he starts the milling machine to process the material. After the milling head 3 processes the raw material into a spline shaft, the moving mechanism 5 adjusts the horizontal position of the clamping assembly 72, and the lifting mechanism 6 adjusts the vertical height of the clamping assembly 72 so that the clamping assembly 72 is located below the workpiece that has been processed. At this time, the fixture 2 relaxes its grip on the workpiece, and the workpiece falls above the clamping assembly 72 to clamp the workpiece. Then the moving mechanism 5 and the lifting mechanism 6 drive the clamping assembly 72 to move to the position of the collection box 4, and place the workpiece inside the collection box 4 to collect the workpiece. There is no need for the user to open the protective door of the machine body 1 to remove the workpiece, which is convenient for the user to process the spline shaft and collect the spline shaft, thereby improving the processing efficiency of the spline shaft.

The body 1 is provided with a moving shell 11, and the moving shell 11 is located at the top of the body 1. The number of the moving shells 11 is equal to the number of the moving screws 52. In the embodiment of the present application, the number of the moving shells 11 is two, and the two moving screws 52 are limited respectively to achieve the working purpose of the two moving mechanisms 5. The length direction of the moving shell 11 is parallel to the horizontal direction, and the two ends of the moving screw 52 are rotatably connected to the two ends of the moving shell 11. The axis of the moving screw 52 is perpendicular to the feeding direction of the milling head 3. The output end of the moving motor 51 is coaxially fixedly connected to the end of the moving screw 52, ​​and the moving screw 52 passes through and is threadedly connected to the moving block 53, and the moving block 53 is slidably connected to the inner wall of the moving shell 11. The lifting mechanism 6 is fixedly connected between the two moving blocks 53, so as to achieve stable connection and stable movement of the lifting mechanism 6 and improve the safety of the present application.

[0034] The moving shell 11 provides an installation position for the moving screw 52, ​​realizing a stable connection of the moving screw 52. At the same time, the moving shell 11 limits the moving block 53, realizing the sliding of the moving block 53 in the horizontal direction. After the moving motor 51 is started, it drives the moving screw 52 to rotate, drives the moving block 53 to move along the axis of the moving screw 52, ​​realizes the horizontal movement of the lifting mechanism 6, causes the collecting mechanism 7 to move, and realizes the clamping of the workpiece.

[0035] Reference Figure 2 and Figure 3 The number of lifting mechanisms 6 is equal to the number of moving mechanisms 5.

The lifting mechanism 6 includes a lifting cylinder 61 fixedly connected to the moving block 53 and a lifting block 62 fixedly connected to the lifting cylinder 61. The cylinder end of the lifting cylinder 61 is fixedly connected to the moving block 53, and the output end of the lifting cylinder 61 is fixedly connected to the lifting block 62 to achieve simultaneous driving of both ends of the lifting block 62. After the lifting cylinder 61 is started, it drives the lifting block 62 to move in the vertical direction, thereby adjusting the vertical height of the clamping assembly 72 and achieving the purpose of clamping the workpiece.

The positioning shaft 712 is rotatably connected between the two lifting blocks 62, so that the movement of the lifting blocks 62 is more stable. The output end of the positioning motor 711 is coaxially fixedly connected to the positioning shaft 712. The positioning block is located at one end of the positioning shaft 712 away from the positioning motor 711 to drive the positioning shaft 712.

[0037] Furthermore, the clamping assembly 72 includes a clamping plate 721 fixedly connected to the positioning shaft 712 and a clamping motor 722 fixedly connected to the clamping plate 721. There are two clamping plates 721, and the two clamping plates 721 are connected to each other. The positioning shaft 712 passes through and is fixedly connected to one of the clamping plates 721. After the user starts the positioning motor 711, the clamping plate 721 is driven to rotate to adjust the inclination angle of the clamping plate 721. The positioning shaft 712 is located on a side away from the other clamping plate 721. There is an angle between the two clamping plates 721. At the same time, the two clamping plates 721 are rotatably connected through a rotating shaft. The clamping motor 722 is fixedly connected to one of the clamping plates 721, and the output end of the clamping motor 722 is coaxially fixedly connected to one end of the rotating shaft of the clamping plate 721, so that the clamping plates 721 can rotate with each other, so that the tops of the clamping plates 721 move in the direction of approaching or moving away from each other, so that the workpiece can fall between the two clamping plates 721, support and clamp the workpiece, and achieve the purpose of clamping the workpiece. After starting the clamping motor 722, the clamping plates 721 are driven to deflect, so that the gap between the clamping plates 721 changes, and spline shafts of different diameters can be clamped, thereby improving the applicability of the present application. While clamping workpieces of different diameters, the clamping position can also be adjusted, so that the clamping of the workpiece is more stable.

[0038] Reference Figure 2 and Figure 4 The collection box 4 is provided with a guide plate 41, which is inclined upward in a direction away from the bottom of the collection box 4, and the top of the guide plate 41 is located outside the collection box 4, and the top of the guide plate 41 is located inside the machine body 1. After the clamping assembly 72 places the workpiece on the guide plate 41, the workpiece falls from the guide plate 41 into the interior of the collection box 4, so that the workpiece is collected.

[0039] When the user uses the present application to retrieve and collect the spline shaft, the moving mechanism 5 is started first, and the moving motor 51 drives the moving screw 52 to rotate, so that the moving block 53 slides along the direction of the moving shell 11, driving the lifting mechanism 6 to approach the spline shaft, and then the lifting cylinder 61 is started, driving the lifting block 62 and the collecting mechanism 7 to be located below the spline shaft. At this time, the moving mechanism 5 is started again, and the clamping plate 721 is adjusted to be located directly below the spline shaft so that the spline shaft can fall between the clamping plates 721, and then the clamping motor 722 is started to adjust the angle between the two clamping plates 721 to achieve stable grasping of the spline shaft; finally, the moving mechanism 5 and the lifting mechanism 6 are started to transport the spline shaft to the position of the collection box 4, and the collection of the spline shaft is completed. The user does not need to keep a close eye on the processing progress at all times, and the user does not need to manually pick up the parts, thereby improving the processing efficiency of the spline shaft.
