Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and specifically provides a batch hydraulic punching and chamfering integrated device. Background Art

[0002] When processing flanges, a drilling device is required to drill a plurality of flange holes on the flange plate. However, most of the current drilling devices have the following problems when drilling flanges: (1) Each time a hole is drilled, only one hole can be drilled on the flange, and multiple holes cannot be drilled on the flange simultaneously, resulting in low drilling efficiency. (2) After the flange drilling is completed, burrs are inevitably attached to the inner wall of the hole, and the two hole openings are also relatively sharp. Therefore, it is necessary to polish the inner wall of the hole and chamfer and polish the hole openings. The current operation is as follows: After the drilling is completed, the flange is removed, and the hole wall is polished manually, and then the hole openings are polished. The polishing efficiency is low and it is very inconvenient. Summary of the Invention

At this time, the first hypotenuse contacts the upper opening of the drill hole, and the second hypotenuse contacts the lower opening of the drill hole. Then, all the second rotating shafts are controlled to rotate simultaneously by the second driving mechanism.

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] Please refer to Figures 1-8 , a batch hydraulic punching and chamfering integrated device, including a chassis 1, a rotating column 2 is rotatably connected to the chassis 1, a turntable 3 is fixed on the rotating column 2, and a plurality of pneumatic chucks 4 distributed in a circle are fixed on the periphery of the turntable 3; a first driving mechanism for driving the rotating column 2 to rotate is arranged in the chassis 1, and the turntable can be driven to rotate through the first driving mechanism. Specifically, the first driving mechanism includes a first motor 25 arranged in the chassis, a first transmission shaft connected to the first motor through a coupling, a first gear 26 connected to the first transmission shaft, and a second gear 27 connected to the rotating column. The first gear 26 meshes with the second gear 27. Starting the first motor 25 drives the first transmission shaft to rotate. Through the cooperation of the first gear 26 and the second gear 27, the rotating column 2 can be driven to rotate, and thus the turntable 3 can be driven to rotate.

[0037] A frame 5 is peripherally connected to the chassis 1. A first lifting mechanism and a second lifting mechanism are installed on the frame 5. A first housing 6 is connected to the first lifting mechanism, and a second housing 7 is connected to the second lifting mechanism. Specifically, the first lifting mechanism includes a first hydraulic cylinder 28 installed on the frame, and first guide rods 29 slidably connected to the frame and located on both sides of the first hydraulic cylinder. The telescopic end of the first hydraulic cylinder 28 is connected to the first housing 6, and the lower end of the first guide rod 29 is also connected to the first housing 6. By controlling the operation of the first hydraulic cylinder 28, the first housing 6 can be driven to lift or lower, and the first guide rod 29 can improve the stability of the lifting of the first housing 6. The second lifting mechanism includes a second hydraulic cylinder 30 installed on the frame, and second guide rods 31 slidably connected to the frame and located on both sides of the second hydraulic cylinder. The telescopic end of the second hydraulic cylinder 30 is connected to the second housing 7, and the lower end of the second guide rod 31 is also connected to the second housing 7. By controlling the operation of the second hydraulic cylinder 30, the second housing 7 can be driven to lift or lower, and the second guide rod 31 can improve the stability of the lifting of the second housing 7.

[0038] Both the first housing 6 and the second housing 7 are located on the projection plane of the circumference where the pneumatic chuck 4 is located. That is, by rotating the turntable 3, the pneumatic chuck 4 can reach directly below the first housing 6 and the second housing 7 one by one. A drilling mechanism is installed on the first housing 6, and a chamfering and grinding mechanism is installed on the second housing 7. The flange below is drilled by the drilling mechanism, and the drilled flange is chamfered and ground by the chamfering and grinding mechanism.

[0039] The drilling mechanism includes a plurality of first rotating shafts 8 rotatably connected to the first housing, and a second driving mechanism provided inside the first housing and used to drive all the first rotating shafts to rotate. All the first rotating shafts 8 are circumferentially distributed. The lower end of each first rotating shaft 8 is connected to a first mounting sleeve 9, and a drill bit 10 is installed on the first mounting sleeve 9. Specifically, the second driving mechanism includes a second motor 32 installed inside the first housing, a second transmission shaft connected to the second motor through a coupling, a third gear 33 connected to the second transmission shaft, and fourth gears 34 connected to each first rotating shaft. The third gear 33 meshes with all the fourth gears 34. By starting the second motor 32, the second transmission shaft is driven to rotate. Through the cooperation of the third gear 33 and the fourth gears 34, all the first rotating shafts 8 are driven to rotate, thereby driving all the drill bits 10 to work simultaneously to drill a plurality of holes in the flange.

[0040] The chamfer grinding mechanism includes a plurality of second rotating shafts 11 rotatably connected to the second housing, and a third driving mechanism disposed in the second housing and used to drive all the second rotating shafts to rotate. All the second rotating shafts 11 are circumferentially distributed. The lower end of each second rotating shaft 11 is connected with a second mounting sleeve 12, and an upper grinding rod 13 is mounted on the second mounting sleeve 12. Specifically, the third driving mechanism includes a third motor 35 mounted in the second housing, a third transmission shaft connected to the third motor through a coupling, a fifth gear 36 connected to the third transmission shaft, and a sixth gear 37 connected to each second rotating shaft. The fifth gear 36 meshes with all the sixth gears 37. Starting the third motor 35 drives the third transmission shaft to rotate. Through the cooperation of the fifth gear 36 and the sixth gear 37, all the second rotating shafts 11 are driven to rotate, so as to drive all the upper grinding rods 13 to rotate simultaneously.

[0041] The chamfer grinding mechanism further includes an extension plate 14 connected to the periphery of the second housing and corresponding to the second rotating shaft. A first cylinder 15 is mounted on each extension plate. The telescopic end of the first cylinder 15 is connected with a mounting seat 16. A second cylinder 17 is mounted in the mounting seat 16. The telescopic end of the second cylinder 17 is connected with a support frame 18. A fourth rotating shaft 43 is rotatably connected to the support frame 18. The lower end of the fourth rotating shaft passes through the support frame, and the passing end extends below the support frame. The upper end of the fourth rotating shaft is fixedly connected with a third mounting sleeve 19, and a lower grinding rod 20 is mounted on the third mounting sleeve 19. By the operation of the second cylinder 17, the lower grinding rod 20 can be aligned with the corresponding upper grinding rod 13. A spline shaft 21 is provided on the bottom surface of the upper grinding rod 13, and a spline groove 22 matching the spline shaft is provided at the upper end of the lower grinding rod 20. By the contraction of the first cylinder 15 and manually rotating the fourth rotating shaft 43 at the same time, when the spline shaft 21 is aligned with the spline groove 22, the spline shaft 21 of the upper grinding rod 13 is inserted into the spline groove 22 of the lower grinding rod 20.

[0042] In addition, the upper grinding rod 13 can also be rotated by an electric means to align the spline shaft 21 with the spline groove 22. Specifically, the spline shaft 21 includes a shaft body and a plurality of transmission strips fixed on the periphery of the shaft body. The spline groove 22 includes a groove body and a plurality of transmission grooves arranged on the periphery of the groove body. The shaft body corresponds to the groove body, and the transmission strips correspond to the transmission grooves one by one. An installation groove is provided on the bottom surface of one of the transmission strips, and a distance sensor 44 is installed in the installation groove. A transparent plate 45 is fixedly connected to the bottom of the installation groove. The transparent plate is made of high-strength transparent glass, such as tempered glass. There is still a certain distance between the transparent plate 25 and the bottom of the transmission strip to prevent the transparent plate from directly contacting the spline groove and reduce the wear of the transparent plate. A cavity is provided in the upper part of the upper grinding rod 13, and a battery pack and a control board 46 are provided in the cavity. A wireless transmission module is provided in the control board 46. The distance sensor 44, the battery pack and the control board are electrically connected. The battery pack provides power for the control board 26 and the distance sensor 44. Accordingly, a battery cover needs to be provided on the upper grinding rod 13 for replacing the battery. When grinding the inner wall of the flange hole, when the lower grinding rod 20 and the upper grinding rod 13 are both aligned with the hole on the flange, at this time, the distance sensor on the transmission strip senses the distance between it and the lower grinding rod 20. At the same time, the third motor 35 rotates slowly, driving the upper grinding rod 13 to rotate slowly. When the distance reaches the maximum, it means that the transmission strip is aligned with the transmission groove, that is, the spline shaft 21 is aligned with the spline groove 22. At this time, the third motor stops working, and at the same time, the first cylinder 15 contracts so that the upper grinding rod and the lower grinding rod can be accurately butted.

[0043] The upper grinding rod 13 and the lower grinding rod 20 have the same length. The diameter of the upper grinding rod 13 becomes smaller from top to bottom, and the diameter of its lower part is equal to that of the drill bit 10. The upper and lower joints of the upper grinding rod 13 are the first bevel edge 23. The lower end of the upper grinding rod 13 can enter from the top of the drill hole and contact the upper opening of the drill hole through the first bevel edge 23 on it. The diameter of the lower grinding rod 20 becomes smaller from bottom to top, and the diameter of its upper part is equal to that of the drill bit 10. The upper and lower joints of the lower grinding rod 20 are the second bevel edge 24. The upper end of the lower grinding rod 20 can enter from the bottom of the drill hole and contact the lower opening of the drill hole through the second bevel edge 24 on it. The inner wall of the drill hole is ground by the lower part of the upper grinding rod 13 and the upper part of the lower grinding rod 20, and the openings of the drill hole are ground by the first bevel edge 23 and the second bevel edge 24 to achieve chamfering.

[0044] In addition, self-tightening drill chucks are provided in the first mounting sleeve 9, the second mounting sleeve 12 and the third mounting sleeve 19 to facilitate the installation and disassembly of the drill bit 10, the upper grinding rod 13 and the lower grinding rod 20. The self-tightening drill chuck is a prior art, and the specific structure and principle thereof will not be described in detail in the present invention.

[0045] A plurality of third rotating shafts 38 corresponding to the pneumatic chucks are rotatably connected to the periphery of the turntable 3. The bottom surface of the pneumatic chuck 4 is connected to the third rotating shaft 38. A plurality of fourth motors 39 corresponding to the third rotating shafts are arranged in the turntable 3. The fourth motor 39 is drivingly connected to the corresponding third rotating shaft 38. By operating the fourth motor 39, the third rotating shaft 38 can be driven to rotate, thereby driving the pneumatic chuck 4 to rotate, so as to finely adjust the flange and align the drilled hole of the flange with the upper grinding rod 13 and the lower grinding rod 20.

[0046] A controller 40 is arranged in the chassis 1. A control panel 41 is arranged on the front side of the chassis 1. A start button and a touch display are arranged on the control panel. The pneumatic chuck 3, the first motor 25, the first hydraulic cylinder 28, the second hydraulic cylinder 30, the second motor 32, the third motor 35, the fourth motor 39, the first cylinder 15, the second cylinder 17, the control panel 41, and the control board 46 are all electrically connected to the controller 40. A control program is written in the controller for controlling the orderly operation of each component. The start button is used to start the device. An input window is arranged on the touch display for inputting set values. Touch buttons for starting each component are also arranged on the touch display.

[0047] In order to improve the efficiency of drilling and grinding, four pneumatic chucks 4 can be arranged on the turntable 3 in a "cross" shape distribution, and the first housing 6 and the second housing 7 are in an L-shaped distribution. Before grinding, by controlling the rotation of the turntable 3, the first pneumatic chuck 4 is aligned with the first housing 6, and at this time the second pneumatic chuck 4 is aligned with the second housing 7. Then set the number of turns of the first motor 25 each time it rotates. Each time the first motor 25 rotates, the turntable 3 rotates 90 degrees. When the turntable 3 rotates each time, the first pneumatic chuck 4 reaches below the second housing 7, and the second pneumatic chuck 4 leaves the second housing 7. By this method, the flanges that have completed drilling can reach below the second housing 7 one by one to grind the drilled holes, realizing batch operation.

[0048] The rotation connection described in this embodiment is a way that two or more components can be rotatably connected together through bearings or other components. This connection method is prior art and will not be described in detail in this embodiment. In addition, in order to reduce the wear of the spline shaft and the spline groove, lubricating oil needs to be added to both regularly. If the wear is large, the upper grinding rod and the lower grinding rod need to be replaced.

[0049] The working principle of the present invention is:

[0050] Fix the flange 42 through the pneumatic chuck 4. Operate the first motor 25 to drive the turntable 3 to rotate, so that the flange reaches directly below the first housing 6. Then control the first hydraulic cylinder 28 to extend, driving the first housing 6 to descend, making the drill bit 10 contact with the flange. Then start the second motor 32 to drive all the drill bits 10 to work simultaneously, and drill a plurality of holes in the flange. After drilling is completed, operate the first motor 25 to drive the turntable 3 to rotate, so that the drilled flange reaches directly below the second housing 7. At this time, a new flange reaches directly below the first housing 6, and new drilling is carried out.

[0051] After the drilled flange reaches directly below the second housing 7, control the fourth motor 39 to work, driving the pneumatic chuck 4 to rotate, so as to finely adjust the flange, making the drilled holes align with the upper grinding rod 13. Then control the second hydraulic cylinder 30 to extend, driving the second housing 7 to descend, making the upper grinding rod 13 insert from the top surface of the drilled hole. Then the second cylinder 17 extends, making the lower grinding rod 20 align with the drilled hole. Then control the first cylinder 15 to contract, making the lower grinding rod 20 rise and insert from the bottom surface of the drilled hole. At this time, through the action of the distance sensor 44 and in cooperation with the operation of the third motor 35, the spline shaft 21 can be aligned with the spline groove 22. If the distance sensor 44 fails, the lower end of the fourth rotating shaft 43 can also be manually rotated to also align the spline shaft 21 with the spline groove 22. After the two are aligned, control the first cylinder 15 to continue contracting until the lower grinding rod 20 is spline-connected to the upper grinding rod 13. At this time, the first hypotenuse 21 contacts the upper opening of the drilled hole, and the second hypotenuse 24 contacts the lower opening of the drilled hole. Then start the third motor 35 to drive all the upper grinding rods to rotate, and the upper grinding rods drive the lower grinding rods to rotate, so that the inner wall of the drilled hole can be ground by the lower part of the upper grinding rod 13 and the upper part of the lower grinding rod 20, and the first hypotenuse 21 and the second hypotenuse 24 grind the two openings of the drilled hole, realizing chamfering, greatly improving the grinding efficiency.

[0052] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
