Detailed implementation mode

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1-9 , a high-efficiency five-axis horizontal turning processing center provided by an embodiment of the present invention includes a machine compartment 1, a central axis 2, a processing table 3 and a driving unit 4. Among them, a cabin door is opened on the front side of the machine compartment 1. The central axis 2 is rotatably connected to the machine compartment 1. A slide rail 2.1 is fixedly connected to the central axis 2 along the length direction. The processing table 3 is slidably connected to the slide rail 2.1. Specifically, a sliding sleeve is fixedly arranged at the bottom of the processing table 3, and the sliding sleeve is slidably sleeved on the slide rail 2.1. The slide rail 2.1 is a non-circular structure, that is, the processing table 3 (sliding sleeve) cannot rotate relative to the slide rail 2.1. During the sliding stroke of the processing table 3 on the slide rail 2.1, there is a processing station located inside the machine compartment 1 and a loading and unloading station located at the cabin door of the machine compartment 1. The loading and unloading station is used to install the workpiece to be processed on the processing table 3 or disassemble the processed workpiece from the processing table 3. It is not conducive to loading and unloading the workpiece when the processing table 3 is located inside the machine compartment 1. It is necessary to move the processing table 3 to the loading and unloading station. The loading and unloading station of the processing table 3 does not have to be completely located outside the cabin door. Preferably, a part of the processing table 3 is located outside the cabin door. The basic principle is that it is convenient for workpiece loading and unloading; the driving unit 4 is arranged on the processing shaft. The power output end 4.1 of the driving unit 4 makes a linear motion along the length direction of the slide rail 2.1. The linear motion of the power output end 4.1 includes a first stage and a second stage. In the first stage, the power output end 4.1 drives the processing table 3 to switch between the loading and unloading station and the processing station through a power distribution component so that the processing table 3 enters and exits the machine compartment 1; in the second stage, the power output end 4.1 drives the processing table 3 located at the processing station to rotate around the axis of the central axis 2 through a power distribution component for processing.

[0027] In the above technical solution, a high-efficiency five-axis horizontal turning processing center provided by the present invention only sets one driving unit 4. Cooperating with the power distribution component, it can realize the switching of the processing table 3 between the loading and unloading station and the processing station, and drive the processing table 3 located at the processing station to rotate around the axis of the central axis 2 for processing, reducing the number of driving sources, greatly reducing the manufacturing cost, and the various processing steps are interlocked with each other, which is beneficial to improving the stability of the processing process.

Among them, the guide rod 5 is rotatably connected to one side of the central shaft 2, the guide rod 5 is parallel to the central shaft 2, a guide groove is provided on the circumferential side of the guide rod 5, the guide groove includes a straight groove 6 opened along the length direction of the guide rod 5 and a spiral groove 7 spirally opened on the guide rod 5, one end of the spiral groove 7 is communicated with one end of the straight groove 6, the straight groove 6 is closer to the hatch door, the sliding part 8 is fixedly connected to the power output end 4.1, and the sliding part 8 is slidably connected to the guide groove. As a preference, in order to further improve the movement stability of the power output end 4.1, the power output end 4.1 is slidably connected to the slide rail 2.1 through a sliding structure; the first wedge block 9 is fixedly connected to the processing table 3, or the first wedge block 9 is fixedly connected to the sliding sleeve, the second wedge block 10 is slidably connected to the power output end 4.1 through a slide rod 16, the inclined surface of the second wedge block 10 is slidably connected to the inclined surface of the first wedge block 9, and the process of the elastic unit 11 restoring deformation drives the second wedge block 10 to slide relative to the first wedge block 9 so that the second wedge block 10 slides relative to the first wedge block 9 to approach the hatch door. The first limit block 12 is fixedly connected to the end of the slide rail 2.1 away from the hatch door, and is used to limit the processing table 3 so that the processing table 3 is located at the processing station. The arc-shaped rack 13 is fixedly connected to the machine cabin 1 through a connecting rod, the tooth surface of the arc-shaped rack 13 is on the inner side, and the center of the arc of the arc-shaped rack 13 is located on the axis of the central shaft 2. The first gear 14 is coaxially fixedly connected to the guide rod 5, and the first gear 14 meshes with the inner side of the arc-shaped rack 13.

[0029] As a preferred technical solution, the driving unit 4 includes a hydraulic cylinder. The cylinder block of the hydraulic cylinder is fixedly connected to the central shaft 2 through a mounting rod, and the hydraulic rod of the hydraulic cylinder is fixedly connected to the power output end 4.1. The hydraulic cylinder drives the power output end 4.1 to perform a linear motion; or the driving unit 4 includes an electric push rod, and the electric push rod drives the power output end 4.1 to perform a linear motion; or the driving unit 4 includes a servo motor, a second gear and a straight rack. The servo motor is fixedly installed on the central shaft 2, the second gear is coaxially fixedly connected to the output shaft of the servo motor, the straight rack is fixedly connected to the power output end 4.1, the length direction of the straight rack is the same as the length direction of the slide rail 2.1, the second gear meshes with the straight rack, and the servo motor drives the straight rack to perform a linear motion through the second gear, and the straight rack drives the power output end 4.1 to move synchronously.

[0030] As a preferred technical solution, a second limit block 15 is fixedly connected to one end of the central shaft 2 close to the hatch door. The second limit block 15 is used to limit the processing table 3 so that the processing table 3 is located at the loading and unloading station, which is beneficial to positioning the processing table 3.

[0031] As a preferred technical solution, the inclined surfaces of the first limiting block 12 and the second limiting block 15 are not in direct contact, but a sliding groove is formed on one of the inclined surfaces of the first limiting block 12 and the second limiting block 15, and a sliding rib is provided on the other, and the sliding rib is slidably connected and matched with the sliding groove.

[0032] As a preferred technical solution, the sliding rod 16 is slidably inserted through the power output end 4.1. One end of the sliding rod 16 is fixedly connected to the second wedge-shaped block 10, and the other end is fixedly connected to a limiting cap 17.

[0033] As a preferred technical solution, the elastic unit 11 is a compression spring, and the compression spring is movably sleeved on the sliding rod 16. One end of the compression spring abuts against the second limiting block 15, and the other end abuts against the power output end 4.1; or the elastic unit 11 is a tension spring, and the tension spring is movably sleeved on the sliding rod 16. One end of the tension spring is fixedly connected to the power output end 4.1, and the other end is fixedly connected to the limiting cap 17.

[0034] In the present invention, when the processing table 3 is located at the loading and unloading station, the driving unit 4 drives the power output end 4.1 to perform a linear motion. Under the drive of the power output end 4.1, the sliding part 8 first slides along the straight groove 6. During this process, the power output drives the second wedge block 10 to move synchronously through the sliding rod 16. The elastic force of the elastic unit makes it impossible for the second wedge block 10 to slide relative to the first wedge block 9. Instead, the second wedge block 10 drives the first wedge block 9 to move synchronously along the slide rail 2.1. Thus, the second wedge block 10 drives the processing table 3 to slide along the guide rail until the processing table 3 abuts against the first limit block 12. At this time, the processing table 3 is exactly located at the processing station, and the sliding part 8 just slides to the junction of the straight groove 6 and the spiral groove 7. This process is the first stage, that is, the process of the sliding part 8 sliding in the straight groove 6 is the first stage; then continue to drive the power output end 4.1 to perform a linear motion through the power unit. Due to the limit block of the first limit block 12, the workbench cannot continue to slide in the direction away from the warehouse door. Instead, the power output end 4.1 drives the second wedge block 10 to have a force to move along the slide rail 2.1 through the sliding rod 16, so that the second wedge block 10 slides relative to the first wedge block 9. At the same time, the second wedge block 10 overcomes the elastic force of the elastic unit 11 and slides relative to the power output end 4.1 through the sliding rod 16, so that the sliding part 8 can continue to slide along the length direction of the slide rail 2.1. The sliding part 8 can slide into the spiral groove 7. The sliding action between the sliding part 8 and the spiral groove 7 causes the guide rod 5 to rotate. The guide rod 5 drives the first gear 14 to rotate. The first gear 14 cooperates with the arc-shaped rack 13, so that the first gear 14 revolves along the arc center (i.e., the axis of the central rod) of the arc-shaped rack 13. Thus, the guide rod 5, the sliding part 8, the power output end 4.1, the power unit, the sliding column, the limit cap 17, the elastic unit 11, the first wedge block 9, the second wedge block 10, the central rod, the guide rail, the first limit block 12, the second limit block 15 and the processing table 3 rotate together along the axis of the central rod to realize the flipping of the processing table 3. If the power output end 4.1 is driven to move in the reverse direction by the driving unit 4, the processing table 3 can be flipped in the reverse direction. This process is the second stage, that is, the process of the sliding part 8 sliding in the spiral groove 7 is the second stage.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
