[0002] With the development of society, people are demanding higher production efficiency and higher processing precision. Laser cutting and punching is an industrial production project that requires both high production efficiency and high precision.

[0003] A hydraulic turbine is a core device that converts the kinetic and potential energy of water into mechanical energy. It is widely used in hydropower generation, pumping stations, and other fields. A hydraulic turbine consists of a runner, guide vanes, volute, draft tube, and spillway cone. The spillway cone is the core flow-guiding component of a reaction turbine. To improve turbine stability, the sidewalls of the spillway cone require cutting and opening.

[0004] Currently, holes are drilled manually on the side walls of the flood cone using a laser cutting machine. Since the flood cone is set at a high position, workers need to climb up to drill the holes, which increases the difficulty of drilling holes and poses certain safety hazards. After drilling the holes, workers need to enter the flood cone to remove the slag on the inner wall of the flood cone, which requires a lot of manpower.

[0005] The patent (CN 115026443 A) discloses a laser drilling and cutting machine, which includes a device base plate, the upper end of which is fixedly connected to two symmetrically arranged support side plates, the upper ends of which are fixedly connected to a first connecting plate, and further includes: a placement base plate, which is connected to the device base plate through a first adjustment unit, a plurality of first placement plates, which are all connected to the placement base plate through a second adjustment unit, a clamping unit, which is arranged on the first placement plate, a power unit, which is arranged on the first connecting plate, and which is connected to the cutting unit and the laser drilling unit through a connecting unit; the above patent can realize drilling operations on tubular or cylindrical workpieces, but is limited to small pipes or cylindrical parts; for large cylindrical workpieces such as flood discharge cones, it cannot effectively fix and drill holes.

[0039] The following is combined with Figure 1-8 This application is described in further detail.

[0040] The embodiment of the present application discloses a laser hole opening device for the engine unit runner flood discharge cone. Figure 1The laser drilling equipment for the engine unit runner flood discharge cone includes a lifting platform 1, a base 2, an annular guide rail 3, a laser drilling assembly 4, a positioning assembly 5 and a drive assembly 6. The lifting platform 1 is an elevator. The specific structure of the elevator is not shown in the figure. Only the load-bearing plane of the elevator is shown, which is located directly below the flood discharge cone. The lifting platform 1 is provided with a base 2, and an annular guide rail 3 is provided above the base 2. The annular guide rail 3 can slide on the base 2. The annular guide rail 3 is sleeved on the outer circumference of the flood discharge cone. There is a space between the inner wall of the annular guide rail 3 and the outer wall of the flood discharge cone to accommodate the laser drilling assembly 4. The laser drilling assembly 4 is provided on the annular guide rail 3 and can rotate along the circumference of the flood discharge cone together with the annular guide rail 3, so that the laser drilling assembly 4 can change the drilling position. The drive assembly 6 is provided on the lifting platform 1 to drive the annular guide rail 3 to rotate.

[0041] Reference Figure 2 and Figure 3 The positioning assembly 5 includes a receiving block 51, a positioning block 52, a driving block 54, a screw 55 and a coil spring 56; the receiving block 51 is slidably arranged on the base 2 along the vertical direction; the positioning block 52 is slidably arranged on the receiving block 51; a guide block 53 is arranged on the top wall of the positioning block 52; a spiral guide rail is arranged on the lower bottom surface of the annular guide rail 3; the guide block 53 is arranged in the spiral guide rail; when the position of the laser drilling assembly 4 needs to be changed, the driving assembly 6 drives the annular guide rail 3 to rotate and drives the positioning block 52 to move away from the flood discharge cone; the driving block 54 is located below the receiving block 51; the driving block 54 is set on the base 2 for radial sliding along the flood discharge cone; a threaded hole is opened on the driving block 54; the screw 55 is rotatably set on the base 2 and cooperates with the threaded hole; one end of the coil spring 56 is connected to the base 2, and the other end is wound around the screw 55 and then connected to the side wall of the screw 55; one side of the top of the driving block 54 is provided with an inclined first guide surface; the bottom surface of the receiving block 51 has an inclined second guide surface; when the end of the positioning block 52 abuts the side wall of the flood discharge cone, the first guide surface and the second guide surface are completely fitted together.

[0042] It should be noted that after the annular guide rail 3 rotates, the time it takes to drive the laser drilling assembly 4 to change position is relatively short, and the change of position can be completed in about two seconds; after the shifting block 521 shifts the driving block 54 to move and causes the positioning block 52 to move downward, the screw rod 55 rotates under the action of the coil spring 56; because when the driving block 54 moves, the force of the annular guide rail 3 driving the positioning block 52 indirectly acts on the driving block 54, so when the screw rod 55 rotates, the speed is relatively fast; however, when the screw rod 55 rotates to drive the driving block 54, it uses the elastic force of the coil spring 56, so the speed of the screw rod 55 is relatively slow, causing the driving block 54 to slowly reset. When the driving block 54 is reset, the annular guide rail 3 has stopped rotating; ensuring that the positioning block 52 abuts against the side wall of the flood discharge cone after the annular guide rail 3 rotates; A through slot 511 is provided on the receiving block 51; a shift block 521 is provided at the bottom of the positioning block 52; the shift block 521 passes through the through slot 511 and abuts against the end of the driving block 54; this facilitates the shift block 521 to push the driving block 54; a positioning plate is provided at the end of the positioning block 52, which fits tightly against the side wall of the flood discharge cone. The positioning plate is an arc-shaped plate, which facilitates the positioning block 52 to stably abut against the side wall of the flood discharge cone.

[0043] Reference Figure 2 and Figure 5 The bottom of the base 2 has a spherical surface, and a bearing groove 11 is provided on the top of the lifting platform 1; the inner wall of the bearing groove 11 fits the spherical surface; two clamping jaws 12 are provided on the lifting platform 1; one end of the two clamping jaws 12 is respectively hinged on the lifting platform 1; the other end of the clamping jaw 12 is a free end; the inner side walls of the two clamping jaws 12 have an arc surface that fits the spherical surface; the outer side walls of the two clamping jaws 12 are respectively connected to the lifting platform 1 with a first spring, and the two first springs can respectively squeeze the two clamping jaws 12 closer to each other, so that the clamping jaws 12 fasten the base 2; to prevent the drawings from being disordered, the two first springs are not shown in the figure.

[0044] Reference Figure 1 and Figure 5 The drive assembly 6 includes a rotating shaft 61, a first gear 62, a cylinder 64, and a rack 66.

[0045] Furthermore, the second gear 63 is coaxially fixed on the rotating shaft 61; the cylinder 64 is arranged on the lifting platform 1; the power output end of the cylinder 64 is provided with a receiving plate 65; the rack 66 is slidably provided on the receiving plate 65; and is engaged with the second gear 63; a first protrusion 651 is provided on the receiving plate 65, and a second protrusion 661 is provided on the rack 66; a second spring 652 is connected between the first protrusion 651 and the second protrusion 661 of the tooth; when the second gear 63 drives the rack 66 to move toward the direction of the clamping jaw 12, the second spring 652 is squeezed.

[0046] It should be noted that the base 2 is composed of alloy rods as a whole, so it is relatively light in weight; the elastic force of the first spring is relatively large, so after the clamping bar pushes the clamping jaws 12 open, the two clamping jaws 12 expand outward to a small extent, ensuring that the base 2 can move.

[0047] See also Figure 6 and Figure 7The slag cleaning component 7 is connected to the annular guide rail 3 through the linkage component 8; the linkage component 8 includes a fixed shaft 81, a support member 82, a third gear 83 and a fourth gear 84; one end of the fixed shaft 81 is set on the annular guide rail 3, and the other end extends toward the direction of the flood discharge cone; the support member 82 is rod-shaped, one end of which is sleeved on the fixed shaft 81 and the other end is a free end; a support shaft 821 is set on the free end of the support member 82, and the third gear 83 is rotatably set on the support shaft 821.

There are three gears 83, and a stopper 781 is provided on the other end of the connecting rod 78. After the third gear 83 rotates, the slag cleaning seat 73 can be driven to rotate through the connecting rod 78, and the stopper 781 can prevent the slag cleaning seat 73 from disengaging from the third gear 83; the slider 75 is set in the slag cleaning seat 73 along the axial sliding of the slide rod 72; one end of the second scraper 76 is hinged to the end of the slider 75, and the other end abuts the inner wall of the flood discharge cone; one end of the connecting rod 77 is hinged to the middle of the second scraper 76, and the other end is hinged to the slag cleaning seat 73; a fourth spring 79 is connected between the slider 75 and the slide rod 72; the fourth spring 79 plays a buffering role, which can prevent the slag cleaning seat 73 from damaging the side wall of the flood discharge cone when the end of the slag cleaning seat 73 abuts against the outer wall of the flood discharge cone.

A third motor and a fourth motor are set on the annular guide rail 3, and the power output shafts of the third motor and the fourth motor are coaxially connected to the second circular base 41 and the third gear 83 respectively; they drive the second circular base 41 and the third gear 83 to rotate respectively.

[0050] The working principle of a laser hole opening device for a turbine runner flood discharge cone in this application is: In the initial state, the annular guide rail 3 is located at the highest point of the flood discharge cone, and the positioning block 52 is in contact with the outer wall of the flood discharge cone. Since no hole is opened at this time, the slag cleaning component 7 does not work.

[0051] During operation, the laser cutting unit 42 is started, and the second motor is started to drive the second circular base 41 to rotate; while the second circular base 41 rotates, the fifth spring squeezes the laser cutting unit 42, and the positioning rod 44 abuts against the correction arc plate 43, so that the laser cutting unit 42 can move along the radial direction of the flood discharge cone; after the hole is opened on the flood discharge cone, the second motor is turned off and the first motor is started; the first motor drives the rotating shaft 61 to rotate, and drives the first gear 62 and the second gear 63 to rotate; after the first gear 62 rotates, it drives the annular guide rail 3 to rotate, changing the position of the laser drilling assembly 4; when the annular track rotates, the positioning block 52 is driven away from the flood discharge cone, and then the lever pushes the driving block 54 to follow the positioning block 52 to move, and the receiving block 51 moves downward along the first guide surface, so that the positioning block 52 is away from the annular guide rail 3 and is no longer driven by the annular guide rail 3, driving When the moving block 54 moves, it also drives the screw 55 to rotate and causes the coil spring 56 to store force; when the guide block 53 on the positioning block 52 is completely out of the spiral track, the coil spring 56 drives the screw 55 to reverse and causes the driving block 54 to rotate toward the direction of the flood discharge cone and push the lever to push the positioning block 52 toward the direction of the flood discharge cone; and squeezes the receiving block 51 to slowly rise until the positioning block 52 is reset; after the third gear 83 rotates, the driving bar moves toward the clamping jaw 12 and opens the clamping jaw 12; after the positioning assembly 5 is re-engaged with the flood discharge cone, the cylinder 64 is driven and the receiving plate 65 is driven to move downward, so that the bar is away from the second gear 63 and the clamping jaw 12, so that the clamping jaw 12 is reset; after the bar is disengaged from the second gear 63, the second spring 652 pushes the bar away from the clamping jaw 12, and finally the cylinder 64 pushes the receiving plate 65 and the rack 66 upward to move upward, and the rack 66 is meshed with the second gear 63.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
