[0046] A first XYZ axis module 13 is fixedly connected to the upper surface of the base 1, and an output end of the first XYZ axis module 13 is fixedly connected to a machine tool spindle plate 14.

When the drilling tool 151 is replaced, the rivet mechanism will loosen the rivet, so that the rivet mechanism separates the machine tool spindle plate 14 and the drilling tool 151 from each other. This is the prior art and will not be elaborated on in detail.

[0047] The side wall of the machine tool spindle plate 14 is provided with a replacement component, which includes a fixed frame 16 fixedly connected to the side wall of the machine tool spindle plate 14, and the side wall of the fixed frame 16 is movably connected with a milling cutter 152, and the side wall of the fixed frame 16 is also tightened by a rivet mechanism.

A sliding groove 23 is provided on the end of the connecting rod 22 away from the rotating block 20.

[0048] The replacement component also includes a rotating circular shell 24 that penetrates and rotatably connects to the top of the fixed frame 16. Six fixed columns 25 are fixedly connected to the outer side of the rotating circular shell 24. The six fixed columns 25 are arranged in a circular array with the center of the rotating circular shell 24 as a reference. The diameter of each fixed column 25 is mutually adapted to the width of the curved groove, the annular groove, and the positioning groove opened in the arc groove wheel 18. A sliding column 26 is slidably connected inside the sliding groove 23. A connecting column 27 is fixedly connected to the end of the sliding column 26 away from the sliding groove 23, and a fixed plate 28 is fixedly connected to the bottom of the connecting column 27.

[0049] The inner wall of the fixed plate 28 is penetrated and fixedly connected with a sliding column 3 29, the inner cavity of the rotating circular shell 24 is slidably adapted to the outer side of the sliding column 3 29, and the sliding column 3 29 has a raised portion, so that the sliding column 3 29 completely forms a limited sliding fit with the rotating circular shell 24, and the bottom of the sliding column 3 29 is fixedly connected with a rotating rod 30, and the two ends of the rotating rod 30 are symmetrically fixedly connected with electromagnets 31, and the electromagnets 31 located at the two ends of the rotating rod 30 are staggered. The inner wall of the fixed frame 16 is fixedly connected with a touch button 2 32, and the touch button 2 32 is located on the movement path of the fixed plate 28, and the touch button 2 32 controls the opening and closing of the rivet mechanism through the controller.

[0050] A tapping assembly is provided on the base 1, and the tapping assembly includes a second XYZ axis module 33 fixedly connected to the top of the base 1, and the output shaft end of the second XYZ axis module 33 is fixedly connected to a tapping die 34, and three touch buttons 9 respectively correspond to their controllers to control the opening and closing of the machine tool spindle plate 14, the tapping die 34 and the detection device 35.

[0051] A detection device 35 is fixedly connected to the top of the base 1 .

[0052] The above implementation works as follows:

[0053] The initialization steps are as follows:

[0054] The staff manually places the parts waiting to be processed between the two rubber plates 6. At this time, the lower surface of the parts waiting to be processed also contacts the upper surface of the fixed plate 4. The staff drives the electric telescopic rod 5, so that the two rubber plates 6 are close to each other and stabilize the parts waiting to be processed, thereby ensuring the stability of subsequent parts processing.

[0055] The working steps are as follows:

[0056] The working steps of connecting the components in series for the first time are as follows:

[0057] As described in the initialization step, when the parts to be processed are fixed, the stepper motor 2 is started and set to rotate 90 degrees clockwise each time it is started. When the stepper motor 2 rotates 90 degrees clockwise for the first time, the stepper motor 2 drives the rotating disk 3 to rotate 90 degrees clockwise, and the rotating disk 3 drives the arc rod 7 to move synchronously. Therefore, the arc rod 7 makes a circular motion with the center of the rotating disk 3 as a reference. The rotating disk 3 rotates 90 degrees clockwise, which means that the arc rod 7 performs a quarter of a circle. When the arc rod 7 performs a quarter of a circle, the arc rod 7 rotates clockwise. When the arc rod 7 moves, the bottom of the arc rod 7 contacts the first arc plate 10, and the continued movement of the arc rod 7 squeezes the top of the arc plate 10, so the arc plate 10 moves vertically downward and slides inside the arc groove 8, and the arc plate 10 pushes the touch button 9 vertically downward. Similarly, the arc plate 10 drives the fixed block 11 to move vertically downward, so the fixed block 11 moves vertically downward and compresses the spring 12. When the arc rod 7 moves a quarter of a circle, the arc rod 7 still resists the arc plate 10, thereby ensuring that the touch button 9 is in a pressed state.

[0058] Therefore, touching button 19 controls the machine tool spindle plate 14 to start. Similarly, the first XYZ axis module 13 moves the machine tool spindle plate 14 to the top of the fixed plate 4 through its XYZ three-axis movement. The machine tool spindle plate 14 starts and drives the drilling tool 151 to drill holes in the parts waiting to be processed. When multiple holes need to be drilled, the machine tool spindle plate 14 cooperates with the first XYZ axis module 13 to drill holes in multiple positions. When all the holes of the parts waiting to be processed are processed, the next milling work is selectively performed according to the needs of the parts. At the same time, the machine tool spindle plate 14 no longer drives the drilling tool 151 to rotate.

[0059] The steps for replacing components are as follows:

[0060] When the next milling operation is required, the stepper motor 2 17 is powered on and started. The stepper motor 2 17 drives the arc groove wheel 18 to slide synchronously through its output shaft end. Therefore, when the arc groove wheel 18 starts to rotate, the rotation of the positioning groove first moves the fixed column 25 clockwise and slides into its inner cavity. Since the six fixed columns 25 are arranged in a circular array with the center of the rotating circular shell 24 as a reference, one fixed column 25 is moved to rotate. At this time, the rotating circular shell 24 rotates sixty degrees clockwise. The clockwise rotation of the rotating circular shell 24 drives the sliding column three 29 to rotate synchronously. At this time, the rotating circular shell 24 rotates sixty degrees clockwise. Therefore, the rotating round shell 24 drives the sliding column 3 29 to rotate 60 degrees, and the sliding column 3 29 drives the rotating rod 30 to rotate 60 degrees clockwise, so that the two ends of the rotating rod 30 respectively contact the drilling tool 151 and the milling tool 152, in order to replace the drilling tool 151 and the milling tool 152. Next, the arc groove wheel 18 continues to rotate, and the fixed column 25 at this time begins to slide along the three annular grooves, so that the fixed column 25 no longer rotates. At the same time, during the half-turn of the arc groove wheel 18, the arc groove wheel 18 drives the elliptical groove 19 to rotate synchronously, so the sliding column 1 21 moves along the elliptical groove. The sliding column 121 slides along the path of the slot 19, and because the oval slot 19 rotates half a circle, the sliding column 121 is driven to slide vertically downward on the oval slot 19, so that the sliding column 121 drives the connecting part of the rotating block 20 and the fixed frame 16 to rotate counterclockwise as an axis, so the rotating block 20 drives the connecting rod 22 to move in an arc in the direction close to the fixed column 25, so the connecting rod 22 pushes the sliding column 26 in the horizontal direction to move away from the connecting rod 22 synchronously through the inner wall of the sliding slot 23, and then the connecting rod 22 drives the sliding column 26 vertically downward through the sliding slot 23, and the sliding column 26 drives the connecting column 27 to move vertically downward , the connecting column 27 drives the fixed plate 28 to move synchronously, so the fixed plate 28 drives the sliding column 3 29 to slide vertically downward inside the rotating circular shell 24, and the fixed plate 28 presses the touch button 2 32 during the descent process. At this time, the touch button 2 32 controls the rivet pulling mechanism to be powered on and started. After the rivet pulling mechanism is powered on, the drilling tool 151 and the milling tool 152 are fixed. At the same time, the electromagnet 31 is powered on to generate magnetism, and the electromagnet 31 magnetically attracts the drilling tool 151 and the milling tool 152. At the same time, during the vertical downward process of the sliding column 3 29, the rotating rod 30 is driven to pull the drilling tool 151 and the milling tool 152 out of the rivet pulling mechanism.

[0061] By replacing the component settings, tool switching can be completed in a short time, drilling and milling can be completed at the same station, avoiding multiple clamping and turnover between equipment, improving the efficiency of part processing, and increasing the accuracy of part processing, avoiding error problems caused by part turnover, and ensuring the accuracy of the processing position.

[0062] When the rotating rod 30 moves vertically downward to the lowest point, the arc groove wheel 18 rotates half a circle, and the fixed column 25 no longer slides in the three annular grooves. At the same time, the arc groove wheel 18 continues to rotate. At this time, the three curved grooves begin to move the fixed column 25, so the fixed column 25 drives the rotating rod 30 to rotate one hundred and eighty degrees, thereby realizing the exchange of positions between the drilling tool 151 and the milling tool 152. Then, when the drilling tool 151 and the milling tool 152 exchange positions, the elliptical groove 19 is also rotating, and the reverse steps of the above process are repeated, so that the rotating rod 30 moves vertically upward, thereby inserting the milling tool 152 vertically upward into the rivet mechanism of the machine tool spindle plate 14.

[0063] When the fixed column 25 no longer continues to slide in the three curved grooves, and the arc groove wheel 18 continues to rotate one circle, the rotating rod 30 slides in the positioning groove again, so that the rotating rod 30 is reset to the initial state at this time.

[0064] The working steps of the second series connection components are as follows:

[0065] When the milling work is completed, the stepper motor 2 continues to rotate 90 degrees. Therefore, when the stepper motor 2 rotates 90 degrees clockwise for the second time, the stepper motor 2 drives the rotating disk 3 to rotate 90 degrees clockwise as well. The rotating disk 3 drives the arc rod 7 to move synchronously. Therefore, the arc rod 7 makes a circular motion with the center of the rotating disk 3 as a reference. The rotating disk 3 rotates 90 degrees clockwise again, which means that the arc rod 7 performs half of the circular motion. When the arc rod 7 performs half of the circular motion, the arc rod 7 The bottom of the arc rod 7 contacts the second arc plate 10, and the continued movement of the arc rod 7 squeezes the top of the arc plate 10, so the arc plate 10 moves vertically downward and slides inside the arc groove 8. The arc plate 10 pushes the touch button 9 vertically downward. Similarly, the arc plate 10 drives the fixed block 11 to move vertically downward, so the fixed block 11 moves vertically downward and compresses the spring 12. When the arc rod 7 completes half of the circular motion, the arc rod 7 still resists the arc plate 10, thereby ensuring that the touch button 9 is in a pressed state.

[0066] The working steps of the tapping assembly are as follows:

[0067] Therefore, the tapping die 34 is powered on and started by touching the button 19. The tapping die 34 cooperates with the second XYZ axis module 33 to tap the parts waiting to be processed. This is the prior art and will not be described in detail.

[0068] When the tapping step is completed, the third step of connecting the components in series is performed:

[0069] When the milling work is completed, the stepper motor 2 rotates 90 degrees for the third time. Therefore, when the stepper motor 2 rotates 90 degrees clockwise for the third time, the stepper motor 2 drives the rotating disk 3 to rotate 90 degrees clockwise as well, and the rotating disk 3 drives the arc rod 7 to move synchronously. Therefore, the arc rod 7 makes a circular motion with the center of the rotating disk 3 as a reference. The rotating disk 3 rotates 90 degrees clockwise for the third time, which means that the arc rod 7 performs three-quarters of a circular motion. When the arc rod 7 performs three-quarters of a circular motion, the arc rod 7 is The bottom of the rod 7 contacts the third arc plate 10, and the continued movement of the arc rod 7 squeezes the top of the arc plate 10, so the arc plate 10 moves vertically downward and slides inside the arc groove 8, and the arc plate 10 pushes the touch button 9 vertically downward. Similarly, the arc plate 10 drives the fixed block 11 to move vertically downward, so the fixed block 11 moves vertically downward and compresses the spring 12. When the arc rod 7 has completed three-quarters of the circular motion, the arc rod 7 is still against the arc plate 10, thereby ensuring that the touch button 9 is in a pressed state.

[0070] Therefore, the button 9 is touched to control the detection device 35 to detect the processed parts. This is the prior art and will not be described in detail.

[0071] The setting of series components not only realizes the function of continuously performing different processing steps on the same workpiece, but also realizes that when the same workpiece moves to different processing steps, the corresponding processing flow can be carried out at the first time, thereby greatly shortening the processing time of parts. At the same time, different functions of parts can be processed on the same machine tool, which effectively avoids the error problem caused by part clamping. At the same time, the equipment is radially distributed around the central axis, which can reduce linear space occupancy compared to a linear arrangement.

[0072] The motion design of the three-step series assembly enables the parts to be processed in an orderly manner, avoiding the confusion caused by multiple processes working at the same time.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
