[0002] In the field of machining, it is usually necessary to perform end face machining on the workpiece. The inner hole machining of the end face, as a common form of machining operation, mainly includes specific machining methods such as drilling, boring, expanding, reaming, and milling. However, no matter which machining method is used, it has a high machining difficulty, especially in blind hole machining. Since it is impossible to observe from the other end of the hole, the machining difficulty is further increased.

[0003] Traditional end face internal hole equipment often uses a single tool head for processing, which can only perform one processing operation at a time, and then needs to be aligned and changed. This alignment and tool change requires a high level of technical skills and experience of the operator; when performing multiple processing operations on the same internal hole, due to the need for repeated alignment and tool change, even if the operator has a high level of technical skills and rich experience, it is difficult to guarantee the processing accuracy and efficiency. In addition, continuous alignment and tool change operations also require a high level of physical strength from the operator. Long-term operation can easily cause operator fatigue, affecting processing quality and efficiency.

[0004] Therefore, developing an end face inner hole processing device that can complete multiple processing operations at one time and improve processing accuracy and efficiency has become an urgent problem to be solved in the current machining field. Utility Model Content

[0023] In this embodiment, the main body of the tooling assembly part is a four-jaw chuck 1. At the same time, a speed motor is also arranged on the outer side of the machine tool corresponding to the four-jaw chuck 1. The speed motor is a stepless speed motor, which can adjust the speed according to the processing requirements to adapt to different materials and processing requirements; the four-jaw chuck 1 can rotate at a high speed relative to the processing part through the speed motor as the tooling assembly part.

[0024] In another embodiment, if the workpiece 3 to be processed is a workpiece that is not a rod or a tube, the tooling assembly unit can also customize the corresponding clamping tooling according to the workpiece structure design, and use the clamping tooling to structurally replace the four-jaw chuck 1 to achieve the clamping of the workpiece; and if such a non-standard clamping tooling is used, the clamping tooling should be equipped with a positioning device, so that after the assembly between the workbench is completed, the adjustment action of the positioning device can be used to ensure that the processing position of the processing part is in the correct position state.

[0025] The processing part of this embodiment includes a processing part base 14, which is fixedly assembled with the machine tool through a detachable assembly structure, and an assembly seat 12 is connected to the processing part base 14 through an electric control translation mechanism 13. The assembly seat 12 is a rigid arm structure and extends to one side of the four-jaw chuck 1. A rotating seat 11 driven by a motor is arranged on the upper surface of the outer end of the assembly seat 12, and an assembly rod frame 16 protruding upward is formed on the top surface of the rotating seat 11. The assembly rod frame 16 is a square rod with a cross section, which is used to realize the assembly of the working unit on the processing part.

[0026] The working unit of this embodiment includes an integrally formed rod-shaped base 6 and a swivel assembly part 8, wherein the swivel assembly part 8 has a square assembly hole matching the assembly rod frame 16, and a bolt assembly hole is reserved on one side of the swivel assembly part 8; during assembly, the working unit is directly pre-assembled at the position of the swivel assembly part 8 through the assembly rod frame 16 and the square assembly hole, and after pre-assembly, the swivel fastening bolt 7 is screwed into the bolt assembly hole in the manner shown in the figure to complete the assembly and fixation of the working unit on the assembly seat 12. The swivel assembly part 8 in the assembled state and the swivel 11 with the assembly rod frame 16 together form a tool head conversion mechanism rotation mechanism for rotating different rod-shaped bases 6 to one side of the processing position; and the combination of the assembly rod frame 16, the square assembly hole and the swivel fastening bolt 7 as a locking mechanism is used to fix the position of the working unit during the processing to ensure the processing accuracy and stability.

[0027] The working unit is formed with a rod-shaped base 6 on both sides of the swivel assembly part 8, and the two rod-shaped bases 6 have the same length. The end of the rod-shaped base 6 corresponding to the left end in the figure is formed with a first tool assembly part and a second tool assembly part, while the end of the rod-shaped base 6 corresponding to the right end in the figure is only formed with a third tool assembly part.
