[0021] When in use, before starting the device, fix the workpiece to be processed on the front of the fixed chuck 33. After it is fixed and stable, start the device through the electric control cabinet 2. After starting the device, the electric control cabinet 2 controls the motor of the feed gear group 34 to start.

[0022] See also Figure 1-6Based on the first embodiment, the present invention provides a technical solution: During the processing, it is sometimes necessary to fine-tune the feed amount of the workpiece. In order to improve the fine-tuning accuracy, a damping feed mechanism 4 is fixedly connected to the back of the chuck shaft seat 32. The damping feed mechanism 4 includes an electromagnetic slide 41. The electromagnetic slide 41 includes a slide and an electromagnetic coil. The electromagnetic coil is supplied with three-phase alternating current. The surface of the slide is covered with a copper layer. The electromagnetic slide 41 is fixedly connected to the back of the chuck shaft seat 32 through the slide, and the electromagnetic slide 41 is fixedly connected to the inside of the slide 12.

[0024] See also Figure 1-12, based on the first and second embodiments, the present invention provides a technical solution: in order to improve the stability of the processing end of the device, a processing adjustment mechanism 5 is fixedly connected to the top of the base 11, and the processing adjustment mechanism 5 is located in the front of the slide 12. The processing adjustment mechanism 5 includes a hydraulic base 51, and the hydraulic base 51 includes a base body 511. A U-shaped blind hole is opened inside the base body 511. The cross section of the U-shaped blind hole of the base body 511 gradually decreases from the right side to the left side. One end of the U-shaped blind hole is connected to the back side of the base body 511. The interior of the U-shaped blind hole of the base body 511 is slidably connected to the pressurizing push rod 36. The interior of the U-shaped blind hole of the base body 511 is loaded with hydraulic oil. A clamping pressure plate 512 is slidably connected to the inner side of the outer surface of the base body 511. A rectangular groove is opened on the outer surface of the clamping pressure plate 512. The clamping pressure plate 512 is slidably connected to the interior of the base body 511 through a spring. A combined processing tower 52 is slidably connected to the top of the base 11. The combined processing tower 52 includes a tower body 521, which is slidably connected to the inside of the base body 511. The back of the tower body 521 is slidably connected to a tool mounting seat 522 through an internal hydraulic rod. The hydraulic rod inside the tower body 521 is connected to an external oil pump device. The tool mounting seat 522 is driven to rotate by an electric motor. There are three tool mounting seats 522 and they are evenly arranged on the back of the tower body 521. The three tool mounting seats 522 are equipped with turning tools, milling cutters, and boring tools. A parallel distance measuring array 523 is fixedly connected to the right side of the tower body 521. The parallel distance measuring array 523 includes three laser distance measuring sensors. A clamping base plate 524 is fixedly connected to the bottom of the tower body 521. The front of the tower body 521 is slidably connected to a screw drive assembly 53, which is fixedly connected to the top of the base 11. The screw drive assembly 53 includes a screw and a screw motor. The screw motor is located at the top of the base 11, and the screw is slidably connected to the front of the tower body 521. A feed brake assembly 54 is fixedly connected to the interior of the slide 12, and the feed brake assembly 54 includes an oil box 541. Two through holes are provided at the bottom of the oil box 541, one of which is connected to the other end of the U-shaped blind hole of the seat body 511 through a one-way valve and a delivery pipe, and the other is connected to one end of the U-shaped blind hole of the seat body 511 through an electromagnetic on-off valve and a delivery pipe. A snap-fit ​​slider 542 is slidably connected to the interior of the oil box 541, and an arc-shaped tooth plate is fixedly connected to the top of the snap-fit ​​slider 542.

[0025] During use, the required tool head is installed on the tool mounting seat 522 according to the processing means to be performed. After the installation is completed, the device is started. Before the horizontal feed mechanism 3 of Example 1 performs the horizontal displacement process, according to the required processing technology, the electric control cabinet 2 adjusts the vertical position of the tower body 521 through the screw drive assembly 53. After the adjustment is completed, the horizontal displacement process of Example 1 is performed. During the forward displacement of the horizontal feed mechanism 3, the pressurizing push rod 36 moves forward, pushing the hydraulic oil inside the seat body 511 to flow from the right end of the U-shaped hole to the left end, and the oil pressure at the left end of the U-shaped hole gradually increases. , the clamping pressure plate 512 is pushed by the oil pressure to approach the clamping base plate 524, and is clamped and fixed with the clamping base plate 524. During this process, the parallel distance measuring array 523 monitors the distance data from the parallel distance measuring array 523 to the fixed chuck 33 in real time and feeds it back to the electric control cabinet 2. The electric control cabinet 2 adjusts the working state of the horizontal feeding mechanism 3 in real time according to the detected distance data. When the horizontal feeding mechanism 3 reaches the predetermined processing position, the electric control cabinet 2 controls the forward and backward movement of the tool mounting seat 522 by controlling the external oil pump device, thereby controlling the feed amount of the tool head to realize the processing of the workpiece; During the displacement of the horizontal feed mechanism 3, as the oil pressure inside the seat body 511 increases, the one-way valve at the bottom of the oil box 541 connects the oil box 541 and the seat body 511 after the oil pressure increases to the opening pressure of the one-way valve, and the hydraulic oil flows into the oil box 541, pushing the engaging slider 542 to slide upward. After the engaging slider 542 slides upward, it engages with the brake gear 543, and the rotation of the brake gear 543 is blocked by the engaging slider 542. At the same time, since the engaging slider 542 is engaged with the sliding tooth plate 31, the sliding tooth plate 31 is assisted in being fixed; When it is necessary to fine-tune the feed amount of the horizontal feed mechanism 3 backward, the electric control cabinet 2 controls the solenoid valve to connect to the seat body 511, and the hydraulic oil inside the oil box 541 flows back to the U-shaped hole of the seat body 511, while promoting the reflux of the hydraulic oil. The clamping slide 542 falls under the action of gravity, the brake gear 543 resumes rotation, the oil pressure inside the seat body 511 drops, and the one-way valve is closed because the oil pressure is lower than its starting pressure.
