The drilling motor 3 is fixed on the lower surface of the mounting table 14, and the lower end of the power shaft of the drilling motor 3 is fixedly connected to a drill chuck. A drill bit 15 is fixedly installed on the drill chuck. A primary support seat 6 and a secondary support seat 7 are fixedly installed on the lower surface of the workpiece table 1. The primary support seat 6 and the secondary support seat 7 are respectively located on both sides of the loading cavity 4, and a primary movable hole 8 and a secondary movable hole 9 are respectively formed on the primary support seat 6 and the secondary support seat 7. A connecting rod 10 is installed in the primary movable hole 8 and the secondary movable hole 9, and the butterfly valve handle 5 to be processed is placed on the connecting rod 10 during processing.

[0038] An avoidance groove 12 is formed on the workpiece positioning plate 2. The drill hole 11 on the butterfly valve handle 5 is formed by drilling with the drill bit 15. The avoidance groove 12 and the drill bit 15 are coaxially arranged, and the diameter value of the avoidance groove 12 is greater than the diameter value of the drill bit 15. The connecting rod 10 and the drill hole 11 are arranged in a staggered manner, and the rod bodies of the butterfly valve handle 5 on both sides of the drill hole 11 are respectively placed on the corresponding connecting rods 10.

[0039] Pick-up grooves 34 are formed at the middle positions near both sides of the loading cavity 4. The pick-up grooves 34 are arranged in a U shape. The arrangement of the pick-up grooves 34 facilitates the staff to pick up the butterfly valve handle 5 to be processed.

[0040] The buffer connecting member includes a primary movable rod 13, a spring force receiving seat 16, and a primary support spring 17. A primary movable rod hole is formed on the mounting table 14. The upper end of the primary movable rod 13 is movably arranged in the primary movable rod hole. A primary threaded rod 18 is integrally formed on the upper end of the primary movable rod 13.

[0041] The first-level movable rod 13 is a regular hexagonal rod structure. The first-level movable rod hole is arranged to match the first-level movable rod 13. When the first-level support spring 17 is in the reset state, the upper side end of the drill bit 15 is higher than the upper surface of the workpiece positioning plate 2. By providing a combined drilling machine for a butterfly valve handle assembly with a workpiece table 1, a workpiece positioning plate 2, and a drilling motor 3, a buffer connecting member composed of the first-level movable rod 13, a spring force receiving seat 16, and the first-level support spring 17 is provided to connect the workpiece positioning plate 2. Then, a single driving structure is used to drive the mounting table 14, so as to position the butterfly valve handle 5 by the workpiece positioning plate 2 and simultaneously drive the drilling motor 3 to press down, thereby completing the drilling process. In this way, the clamping of the workpiece positioning plate 2 and the pressing-down action of the drilling motor 3 are integrated together, effectively optimizing the driving structure of the equipment and facilitating the daily circuit inspection and maintenance of the equipment.

[0042] Embodiment 2: On the basis of Embodiment 1, the root of the connecting rod 10 is fixedly welded to the connecting beam 21. A first-level wedge seat 22 is fixedly installed on the side wall of the connecting beam 21. A connecting seat 23 is integrally formed on the side wall of the spring force receiving seat 16. The connecting seat 23 is arranged in a Z shape. A second-level movable rod hole is opened in the connecting seat 23. A set of second-level movable rod holes are symmetrically opened, and second-level movable rods 24 are movably installed in the second-level movable rod holes. A second-level screw rod 25 is integrally formed on the upper side end of the second-level movable rod 24. A second-level limit retaining ring 27 is positioned and installed on the second-level screw rod 25 through a second-level nut 26. A second-level wedge seat 28 is fixedly connected to the lower side end of the second-level movable rod 24. A second-level support spring 29 is sleeved on the second-level movable rod 24. The two ends of the second-level support spring 29 are respectively abutted against the connecting seat 23 and the second-level wedge seat 28. A spring connecting seat 30 is fixedly connected to the lower side surface of the workpiece table 1. A set of spring connecting seats 30 are symmetrically arranged, and the spring connecting seats 30 are correspondingly arranged with the ends of the connecting beam 21. A third-level support spring 31 is arranged between the end of the connecting beam 21 and the spring connecting seat 30.

[0043] The inclined surfaces of the first-stage wedge seat 22 and the second-stage wedge seat 28 are correspondingly arranged. When the third-stage support spring 31 is in the reset state, there is an overlapping area in the horizontal plane projection of the inclined surfaces of the first-stage wedge seat 22 and the second-stage wedge seat 28. And at this time, the end of the lifting rod 10 completely disengages from the second-stage movable hole 9, and the end of the lifting rod 10 is completely received into the first-stage movable hole 8. A workpiece conveying belt is arranged directly below the loading cavity 4. By arranging the first-stage lifting seat 6 and the second-stage lifting seat 7 to install the lifting rod 10, a first-stage wedge seat 22 is arranged on the connecting beam 21 at the root of the lifting rod 10, a connecting seat 23 is arranged on the side wall of the spring force-receiving seat 16, and a second-stage movable rod 24, a second-stage wedge seat 28 and a second-stage support spring 29 are arranged on the connecting seat 23. Thus, during the process of the installation table 14 pressing down, the driving of the lifting rod 10 can be synchronously realized, so that when the installation table 14 returns to the half-way state, the lifting rod 10 can be automatically retracted by the action of the third-stage support spring 31, so that the drilled butterfly valve handle 5 can automatically fall onto the workpiece conveying belt below, thus completing automatic unloading, and improving the operation convenience of the device.

[0044] Embodiment 3: On the basis of Embodiment 2, when the hydraulic structure is in the half-way state, the first-stage wedge seat 22 and the second-stage wedge seat 28 are in contact with each other. And at this time, both the second-stage support spring 29 and the third-stage support spring 31 are in the compressed state. And at this time, the distance value between the workpiece positioning plate 2 and the workpiece table 1 is greater than twice the thickness value of the butterfly valve handle 5. And at this time, the end of the lifting rod 10 is inserted into the second-stage movable hole 9, and the edge position of the end of the lifting rod 10 is chamfered.

[0045] When the hydraulic structure is in the maximum stroke state, the drill bit 15 completes the drilling of the butterfly valve handle 5. When the hydraulic structure is in the reset state, the first-stage support spring 17, the second-stage support spring 29 and the third-stage support spring 31 are all in the reset state.

[0046] Working principle: In actual use, when the hydraulic structure progresses to the half-way state, a force is generated between the first-stage wedge seat 22 and the second-stage wedge seat 28, so that the end of the latch 10 is inserted into the second-stage movable hole 9. Then, the operator places the butterfly valve handle 5 in the load cavity 4. Then, the hydraulic structure continues to progress. When the drill bit 15 contacts the butterfly valve handle 5, the drilling motor 3 is started, driving the drill bit 15 to drill the butterfly valve handle 5. After the drilling is completed, the drilling motor 3 stops, and the hydraulic structure moves back. When the hydraulic structure is fully retracted, the first-stage wedge seat 22 and the second-stage wedge seat 28 are separated. Thus, under the reset action of the third-stage support spring 31, the latch 10 is reset, so that the butterfly valve handle 5 loses the supporting force of the latch 10, and the butterfly valve handle 5 automatically falls on the workpiece conveying belt to complete automatic unloading. Moreover, when the latch 10 is fully retracted into the first-stage movable hole 8, the surface of the latch 10 can be automatically cleaned, thus avoiding scratches on the next butterfly valve handle 5 to be processed caused by chips remaining on the latch 10, effectively ensuring the yield rate of the product.

[0047] Although the above-described illustrative specific embodiments of the present application have been described to enable those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all application creations using the concept of the present application are within the scope of protection.
