[0011] like Figure 1-2 As shown, this utility model provides a dual-station drilling and tapping center 1 for disc-shaped workpieces, including a dual-station drilling and tapping center 1, a gantry robot, and loading / unloading channels. The dual-station drilling and tapping center 1 is equipped with a drilling station 3 and a chamfering station. Figure 1 Or attached Figure 2Because the pneumatic door 7 of the chamfering station is closed, the chamfering station is obscured and not shown. The drilling equipment 22 of the dual-station drilling and tapping center 1 is set above the drilling station 3. The drilling equipment 22 drills holes in the disc-shaped workpiece. The chamfering equipment 23 of the dual-station drilling and tapping center 1 is set above the chamfering station to perform chamfering processing on the disc-shaped workpiece. There are two sets of loading and unloading robots 2. The two sets of loading and unloading robots 2 are used to grip different disc-shaped workpieces. The two sets of loading and unloading robots 2 are respectively set on the first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly. The first Z-axis displacement drive assembly drives one set of loading and unloading robots 2 along the Z1 axis, and the second Z-axis displacement drive assembly drives the other set of loading and unloading robots 2 along the Z2 axis. The first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly are respectively set on the X-axis displacement drive assembly. The X-axis displacement drive assembly drives the first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly, as well as the components installed on the first Z-axis displacement drive assembly. The loading / unloading robot 2 on the first Z-axis and second Z-axis displacement drive assembly moves along the X-axis. The X-axis displacement drive assembly is located on the top of the truss, and the truss installs and supports the first Z-axis displacement drive assembly, the second Z-axis displacement drive assembly, and the X-axis displacement drive assembly on it. The loading / unloading channels include a roller loading channel 4 and a roller unloading channel 5. The roller loading channel 4 is a channel for loading disc-shaped workpieces, and the roller unloading channel 5 is a channel for unloading disc-shaped workpieces. The dual-station drilling and tapping center 1 is equipped with a tool positioned above the drilling station 3. The drilling station pneumatic door 6 is opened, and disc-shaped workpieces can be placed on the drilling station 3 through the drilling station pneumatic door 6. The drilling equipment 22 is used to drill the disc-shaped workpieces placed on the drilling station 3. The dual-station drilling and tapping center 1 is also equipped with a chamfering station pneumatic door 7 set above the chamfering station. Disc-shaped workpieces can be placed on the chamfering station through the chamfering station pneumatic door 7. The chamfering equipment 23 is used to chamfer the disc-shaped workpieces placed on the chamfering station.

[0012] This invention features a dual-station drilling and tapping center 1 with two processing stations. The dual-station drilling and tapping center 1 utilizes a drilling station 3 and a chamfering station. The dual stations allow for simultaneous drilling and chamfering of disc-shaped workpieces. A gantry robot 2, driven by a dual Z-axis displacement drive assembly (first and second Z-axis displacement drive assemblies), moves along the Z1 and Z2 directions. The Z1 direction is perpendicular to the drilling station 3, and the Z2 direction is perpendicular to the chamfering station. The two sets of loading and unloading robots 2 grip the disc-shaped workpieces, allowing for drilling and chamfering of workpieces at different stations. This eliminates the need for waiting for parts, resulting in shorter cycle times and higher efficiency.

[0013] Roller conveyors are installed on roller feeding channel 4 and roller unloading channel 5 respectively. The roller conveyors transport discs. Unprocessed disc workpieces are placed on roller feeding channel 4 and transported to the gripping position. The loading and unloading robot 2 of the gantry robot grabs the workpiece from roller feeding channel 4 and puts it into two workstations for processing. The processed disc workpiece is grabbed again by loading and unloading robot 2 and placed on roller unloading channel 5. The disc workpiece is then transported and unloaded by roller conveyor.

[0014] The truss includes truss columns 8 and truss main support 9. The truss main support 9 is located on the top of the truss columns 8. The X-axis displacement drive assembly is located above the truss main support 9. The loading and unloading robot 2 is supported and installed on the truss through the truss. The top of the truss main support 9 is provided with the guide and drive structure of the X-axis displacement drive assembly.

[0015] The X-axis displacement drive assembly includes an X-axis slide plate 10, an X-axis guide rail 11, and an X-axis servo motor 12. The X-axis slide plate 10 and the X-axis guide rail 11 are slidably engaged. The output shaft end of the X-axis servo motor 12 is provided with a drive gear that engages with the X-axis rack 13 on the X-axis guide rail 11. The long axis of the X-axis rack 13 and the long axis of the X-axis guide rail 11 both move along the X-axis direction. The first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly are mounted on the X-axis slide plate 10. The X-axis guide rail 11 and the X-axis rack 13 are fixed to the truss main support 9. The X-axis servo motor 12 is fixedly installed on the X-axis slide plate 10. When the X-axis servo motor 12 is started, the drive gear at the end of the X-axis servo motor 12 engages with the X-axis rack 13, driving the X-axis slide plate 10 to slide on the X-axis guide rail 11. The X-axis slide plate 10 drives the first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly to move along the X-axis direction, thereby driving the loading and unloading robot 2 on the first Z-axis displacement drive assembly and the second Z-axis displacement drive assembly to move along the X-axis direction.

[0016] The first Z-axis displacement drive assembly includes a Z1-axis slide plate 14, a Z1-axis guide rail 15, and a Z1-axis servo motor 16. The Z1-axis slide plate 14 and the Z1-axis guide rail 15 are slidably engaged. The output shaft end of the Z1-axis servo motor 16 is provided with a drive gear that engages with the Z1-axis rack 17 on the Z1-axis guide rail 15. The long axis of the Z1-axis rack 17 and the long axis of the Z1-axis guide rail 15 both move along the Z1 direction. The Z1-axis servo motor 16 is fixed on the Z1-axis slide plate 14. When the Z1-axis servo motor 16 is started, the Z1-axis servo motor 16 engages with the Z1-axis rack 17 through the drive gear at the end of its output shaft, driving the Z1-axis slide plate 14 to slide on the Z1-axis guide rail 15. The Z1-axis slide plate 14 drives the loading and unloading robot 2 to move along the Z1-axis direction.

[0017] The first Z-axis displacement drive assembly includes a Z2-axis slide plate 18, a Z2-axis guide rail 19, and a Z2-axis servo motor 20. The Z2-axis slide plate 18 and the Z2-axis guide rail 19 are slidably engaged. The output shaft end of the Z2-axis servo motor 20 is provided with a drive gear that engages with the Z2-axis rack 21 on the Z2-axis guide rail 19. The long axis of the Z2-axis rack 21 and the long axis of the Z2-axis guide rail 19 both move along the Z2 direction. The Z2-axis servo motor 20 is fixed on the Z2-axis slide plate 18. When the Z2-axis servo motor 20 is started, the Z2-axis servo motor 20 engages with the Z2-axis rack 21 through the drive gear at the end of its output shaft, driving the Z2-axis slide plate 18 to slide on the Z2-axis guide rail 19. The Z2-axis slide plate 18 drives the loading and unloading robot 2 to move along the Z2-axis direction.

[0018] Two sets of loading and unloading robots 2 are respectively set on Z1-direction slide 14 and Z2-direction slide 18. Z1-direction slide 14 moves along the Z1 direction under the drive of Z1-direction servo motor 16, so that the loading and unloading robots 2 on Z1-direction slide 14 can put the gripped disc-shaped workpieces into the drilling station 3 and pick up the disc-shaped workpieces from the drilling station 3. Z2-direction slide 18 moves along the Z2 direction under the drive of Z2-direction servo motor 20, so that the loading and unloading robots 2 on Z2-direction slide 18 can put the gripped disc-shaped workpieces into the chamfering station and pick up the disc-shaped workpieces from the chamfering station.

[0019] This utility model is an automated production line that operates simultaneously. When the workpieces at the drilling station 3 and the chamfering station are processed synchronously, the operation is as follows: The X-axis servo motor 12 is started, driving the gantry robot to move laterally to above the roller feed channel 4. At this time, the Z1-axis servo motor 16 is started, driving downwards via gears and racks to grab the unprocessed workpiece A from the roller feed channel 4. After grabbing, the X-axis servo motor 12 is started again, driving workpiece A on the first Z-axis displacement drive assembly to above the pneumatic door 6 of the drilling station. At this time, workpiece B at the drilling station is drilled, the pneumatic door 6 of the drilling station opens, and the Z2-axis servo motor 20 is started, using the loading / unloading robot 2 on the Z2-axis slide plate 18 to grab workpiece B. The loading / unloading robot 2 on the Z1-axis slide plate 14 places workpiece A at this station for drilling. The loading / unloading robot 2 on slide plate 14 and the loading / unloading robot 2 on slide plate 18 move upwards simultaneously. The pneumatic door 6 of the drilling station 3 closes, and the drilling equipment 22 drills workpiece A. Then, the loading / unloading robot 2 on slide plate 18 carries workpiece B to the chamfering station. At this time, the chamfering of workpiece C at the chamfering station is completed (the drilling of C is completed before chamfering). Then, the loading / unloading robot 2 on slide plate 14 descends and grabs workpiece C. The loading / unloading robot 2 on slide plate 18 then places workpiece B at this station. The pneumatic door 6 of the drilling station closes, and the chamfering equipment 23 drills workpiece B. At this time, the loading / unloading robot 2 on slide plate 14 carries the finished workpiece C to the roller feed channel 4 to complete the unloading. This cycle repeats continuously.
