Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1:

[0037] Please refer to Figures 1 to 6As shown in the figure, a precision hole-opening device for molybdenum alloy plates with a positioning mechanism includes a hole-opening frame 1 and a protective top frame 2. The protective top frame 2 is fixedly arranged at the top of the hole-opening frame 1, and a feeding frame 3 and a discharging frame 4 are respectively and fixedly arranged on both sides of the hole-opening frame 1. Feeding openings are arranged on both sides of the top of the hole-opening frame 1, and guiding rollers 5 are rotatably arranged inside the feeding openings, the feeding frame 3, and the discharging frame 4. When precisely opening holes in the molybdenum alloy plate, the molybdenum alloy plate is fed into the interior of the hole-opening frame 1 through the feeding frame 3 and the feeding opening on one side of the feeding frame 3. During the transportation of the molybdenum alloy plate, the guiding rollers 5 rotating inside the feeding frame 3 and the feeding opening are used for guiding and transporting the molybdenum alloy plate, avoiding significant wear on the bottom of the molybdenum alloy plate during transportation. After the precision hole-opening processing of the molybdenum alloy plate is completed inside the hole-opening frame 1, the molybdenum alloy plate is sent out by the discharging frame 4 and the guiding rollers 5 rotating inside the feeding opening on one side of the discharging frame 4. The rotating guiding rollers 5 are used to realize the rolling feeding and rolling discharging of the molybdenum alloy plate, thus greatly reducing the wear on the bottom surface of the molybdenum alloy plate during transportation.

[0038] Further, a number of support columns 6 are movably arranged inside the hole-opening frame 1, and feeding balls 7 are rotatably arranged at the tops of the number of support columns 6.

When controlling the transportation of the molybdenum alloy plate inside the hole-opening frame 1, the driving end of the micro electric cylinder is used to control the support columns 6 to approach the bottom of the molybdenum alloy plate until the feeding balls 7 at the tops of the support columns 6 contact the bottom surface of the molybdenum alloy plate. The feeding balls 7 rotatably arranged at the tops of the support columns 6 are used to roll-support the bottom surface of the molybdenum alloy plate, thus greatly reducing the wear on the bottom surface of the molybdenum alloy plate during transportation.

[0039] Further, a first positioning component is movably arranged inside the hole-opening frame 1, and a second positioning component is movably arranged inside the protective top frame 2. By the first positioning component and the second positioning component working together, the molybdenum alloy plate is quickly positioned and clamped inside the hole-opening frame 1, and the hole-opening positions on the molybdenum alloy plate are quickly positioned, greatly improving the precision hole-opening processing efficiency of the molybdenum alloy plate.

The driving ends of the number of first servo cylinders 9 are used to control the up and down movement of the first positioning frame 8 inside the activity slot. During the process of transporting the molybdenum alloy plate, by controlling the first positioning frame 8 to move downward, interference caused by the first positioning frame 8 to the transportation of the molybdenum alloy plate inside the perforating frame 1 is avoided. When positioning the molybdenum alloy plate, the driving end of the first servo cylinder 9 is used to control the first positioning frame 8 to move upward, and the height of the first positioning frame 8 is flexibly adjusted according to the thickness of the molybdenum alloy plate.

[0041] A first positioning slot 10 is provided inside the first positioning frame 8, and a positioning plate 11 is arranged to slide up and down through a micro cylinder above the inside of the first positioning slot 10. After the molybdenum alloy plate is sent into the first positioning slot 10 inside the first positioning frame 8, the two sides of the molybdenum alloy plate are controlled to be in contact with the two side walls of the first positioning slot 10 respectively. At this time, the driving ends of a number of micro cylinders arranged inside the first positioning frame 8 are used to control the positioning plate 11 inside the first positioning slot 10 to move downward until the bottom of the positioning plate 11 is in contact with the top of the molybdenum alloy plate. The positioning plate 11 is used to position and clamp the molybdenum alloy plate inside the first positioning slot 10 to ensure the stability of the molybdenum alloy plate during the precision perforating process.

[0043] It should be noted that when positioning and controlling the molybdenum alloy plate inside the punching frame 1, first, the molybdenum alloy plate is conveyed into the inside of the punching frame 1. The feeding balls 7 at the tops of several support columns 6 are used to roll-feed the molybdenum alloy plate until the molybdenum alloy plate completely enters the inside of the punching frame 1. The driving ends of several servo cylinders 9 are used to control the lifting of the first positioning frame 8 upward. At the same time, the second positioning frame 12 is controlled to move downward through the first driving block 14. The third positioning frame 13 on one side of the second positioning frame 12 is used to approach the left side of the molybdenum alloy plate until the left side of the molybdenum alloy plate contacts one side of the inner wall of the second positioning groove 16. Then, the third positioning frame 13 is continuously controlled to slide to the right along the second positioning frame 12, and the right side of the molybdenum alloy plate is pushed by the third positioning frame 13 to contact the right side of the inner wall of the first positioning groove 10. Finally, the second driving block 30 is controlled to move backward along the third positioning frame 13 until one side of the telescopic limiting frame 15 contacts the front surface of the molybdenum alloy plate. At the same time, the telescopic limiting frame 15 pushes the rear side of the molybdenum alloy plate to contact the back surface of the inner wall of the first positioning groove 10, and the front surface of the molybdenum alloy plate is limited by the telescopic limiting frame 15. At this time, the positioning plate 11 inside the first positioning groove 10 and the positioning block 17 inside the second positioning groove 16 are controlled to move downward until the bottoms of the positioning plate 11 and the positioning block 17 contact the top of the molybdenum alloy plate, completing the positioning and clamping of the molybdenum alloy plate inside the first positioning groove 10 and the second positioning groove 16, ensuring the stability of the molybdenum alloy plate during the precision punching process, and thus greatly improving the punching precision of the molybdenum alloy plate.

[0044] In a specific embodiment, in the present invention, the first positioning frame 8 that can move up and down is arranged inside the punching frame 1, the second positioning frame 12 that can move up and down is arranged inside the protective top frame 2, and at the same time, the movable third positioning frame 13 is arranged on one side of the second positioning frame 12. The first positioning groove 10 and the positioning groove arranged inside the first positioning frame 8 and the third positioning frame 13 are used to clamp and position the two side surfaces and the rear side surface of the molybdenum alloy plate. At the same time, the telescopic limiting frame 15 located at the front side is used to limit and control the front side surface of the molybdenum alloy plate, greatly improving the stability of the molybdenum alloy plate during the punching process. And through the cooperative action among the first positioning frame 8, the second positioning frame 12, and the third positioning frame 13, the molybdenum alloy plates of different sizes and specifications can be positioned and clamped, solving the problem that the positioning structure used in the current punching process of molybdenum alloy plates has a constant applicable specification and cannot play a fast and effective positioning and clamping role for molybdenum alloy plates of different sizes and specifications, and has poor applicability.

[0045] Embodiment 2:

[0046] Specifically, in this embodiment, a connection structure for precision hole opening of a molybdenum alloy plate is also disclosed. An installation frame 18 is fixedly arranged above the interior of the protective top frame 2. Inside the installation frame 18, two movable frames 19 are slidably arranged left and right through an electric slide table. At the bottom of each of the two movable frames 19, an adjustment frame 20 is slidably arranged front and back through an electric slide table. At the bottom of each of the two adjustment frames 20, a connection frame 21 is fixedly arranged. At the bottom of the two connection frames 21, a laser hole opener 22 and a drill bit hole opener 23 are respectively fixedly arranged. The laser hole opener 22 is composed of a laser generator, an optical fiber, a focusing lens, and a blowing pipe. The drill bit hole opener 23 is composed of a drilling motor, a drill bit mounting seat, and a hole opening drill bit.

[0047] Furthermore, on one side of the top of each of the two adjustment frames 20, a servo cylinder two 24 is fixedly arranged. The driving ends of the two servo cylinders two 24 are respectively fixedly connected to the top of the two connection frames 21. Around the top of the connection frame 21, four limit slide rods 25 are fixedly arranged. The top ends of the four limit slide rods 25 all penetrate through the adjustment frame 20 and extend above the adjustment frame 20.

[0048] Furthermore, on the back and the upper side of the inner wall of the positioning frame one 8, movable grooves 26 are arranged. Inside the two movable grooves 26, laser emitters 27 are slidably arranged through an electric slide table. When positioning the hole opening position, according to the hole opening position, the positions of the laser emitters 27 inside the two movable grooves 26 are adjusted. Through the two laser emitters 27 emitting laser beams, the intersection position of the two laser beams is the hole opening position.

[0049] It should be noted that when performing hole opening processing on the molybdenum alloy plate, by adjusting the position of the movable frame 19 and simultaneously adjusting the position of the adjustment frame 20 at the bottom of the movable frame 19, ensure that the processing position of the laser hole opener 22 or the drill bit hole opener 23 coincides with the intersection point of the two laser beams. Then, use the driving end of the servo cylinder two 24 to control the connection frame 21 to move downward, and use the laser hole opener 22 or the drill bit hole opener 23 to perform hole opening processing on the molybdenum alloy plate.

[0050] In a specific embodiment, when performing precision hole opening on the molybdenum alloy plate, select the corresponding hole opening method according to the thickness of the molybdenum alloy plate. First, use the drill bit hole opener 23 to perform rough hole opening processing on the molybdenum alloy plate, and then use the laser hole opener 22 to perform precision reaming processing on the molybdenum alloy plate. By combining the drill bit hole opener 23 and the laser hole opener 22, it can effectively reduce the hole opening time on the molybdenum alloy plate, and at the same time shorten the time required for laser hole opening. In addition, by using the drill bit hole opener 23 to pre-determine the approximate position and size of the hole, it can avoid material waste caused by errors that may occur in laser hole opening processing, and further improve the hole opening precision of the molybdenum alloy plate.

A dust collection box 29 is fixedly arranged inside the opening machine frame 1, and the inside of the dust collection box 29 is communicated with the inside of the two dust suction openings 28 through a dust suction pump. When performing the opening process on the molybdenum alloy plate, the waste chips and dust generated during the opening process are sucked through the two dust suction openings 28 on the first positioning frame 8, avoiding the pollution of the inside of the opening machine frame 1 by the processing waste chips and dust.

[0057] Step 4: At this time, control the positioning plate 11 inside the first positioning groove 10 and the positioning block 17 inside the second positioning groove 16 to move downward until the bottoms of the positioning plate 11 and the positioning block 17 contact the top of the molybdenum alloy plate, completing the positioning and clamping of the molybdenum alloy plate inside the first positioning groove 10 and the second positioning groove 16;

[0058] Step 5: When performing the opening process on the molybdenum alloy plate, adjust the positions of the laser emitters 27 inside the two movable grooves 26 according to the opening position, and emit laser beams through the two laser emitters 27.
