Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe drilling, in particular to a metal corrugated pipe drilling device. Background Art

[0002] A metal bellows is a metal pipe with a corrugated shape, usually made of metal materials such as stainless steel, and has certain flexibility and bending properties. A leakage pipe is a specially designed metal bellows with a certain number of small holes on its surface. It is made by drilling a metal bellows and is used to achieve pressure relief or fluid discharge under specific conditions, thereby ensuring safe operation under overpressure or overflow conditions. It is widely used in discharge pipes or equipment in chemical, petroleum, food processing and other industries. Drilling is one of the most important steps in the leakage pipe processing process.

[0003] When drilling a hole in a metal bellows, it needs to be fixed first. After it is fixed, the drilling machine is controlled to drill the hole. After the drilling is completed, the drilling machine needs to be moved a certain distance to drill the next position. When the drilling on one side of the metal bellows is completed, it needs to be rotated a certain angle to drill the other side. The above drilling method still has the following shortcomings: 1. When the existing drilling equipment is drilling, the up and down movement and horizontal movement of the drilling machine require independent power sources to control. The use of multiple power sources increases the production cost. At the same time, the use of different power sources will increase the difficulty of mutual coordination. There is a certain time interval between the up and down movement and the horizontal movement, which affects the drilling efficiency; 2. After completing the drilling on one side, the metal bellows needs to be rotated a certain angle to drill the other side. The rotation and fixation of the metal bellows take a lot of time, which affects the drilling efficiency. Summary of the invention

[0012] In a possible implementation, the pressing mechanism and the drilling mechanism are both installed on the slide block, and the pressing mechanism and the drilling mechanism are alternately arranged.

[0013] In one possible implementation, the clamping mechanism includes an elastic telescopic rod fixedly mounted on the left side of the slider, the telescopic end of the elastic telescopic rod being fixedly connected to an arc-shaped pressure plate 2 on the side close to the shell axis, and the arc-shaped pressure plate 2 being fixedly connected to a side away from the shell axis with guide rods symmetrically distributed on both sides of the width direction of the elastic telescopic rod.

[0036] The driving rod 323 drives the bevel gear ring 322 and the hollow turntable 321 to rotate through the bevel gear, and then the hollow turntable 321 drives the slider 313 to move along the slide groove 312 toward the direction close to the axis of the shell 311 through the flat thread, so that the shell 311 can drive the clamping mechanism 5 and the drilling mechanism 6 to approach the metal bellows 7 for clamping and drilling.

[0037] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 The reciprocating moving component 42 includes a driving turntable 421 rotatably installed inside the support frame 41, the edge of the rear side of the driving turntable 421 is rotatably connected to the connecting rod 422, and the end of the connecting rod 422 away from the driving turntable 421 is rotatably connected to the first rack 423, the first rack 423 is meshed with the driving gear 324, and a guide groove 424 is fixedly installed on the front side of the shell 311, and the first rack 423 is slidably installed on the front side of the guide groove 424.

[0038] See also Figure 1 , Figure 2 and Figure 3 The pressing mechanism 5 and the drilling mechanism 6 are both installed on the slider 313, and the pressing mechanism 5 and the drilling mechanism 6 are alternately arranged.

[0039] The driving motor 2 44 drives the driving turntable 421 to rotate, and the driving turntable 421 drives the first rack 423 to move back and forth along the guide groove 424 through the connecting rod 422, and then the first rack 423 drives the driving gear 324 to rotate forward and reverse, which can periodically drive the movable mechanism 3, so that the movable mechanism 3 drives the clamping mechanism 5 and the drilling mechanism 6 to approach the metal bellows 7 for clamping and drilling, and drives the clamping mechanism 5 and the drilling mechanism 6 away from the metal bellows 7 after the drilling is completed.

[0040] See also Figure 1 , Figure 5 , Figure 6 and Figure 7The intermittent moving component 43 includes a toggle plate 431 coaxially fixedly connected to the driving turntable 421, a groove wheel 432 is rotatably installed inside the support frame 41, the groove wheel 432 matches the toggle plate 431, a moving gear 433 is coaxially fixedly connected to the groove wheel 432, a second rack 434 is fixedly connected between the front faces of the two fixing mechanisms 1, and the moving gear 433 is meshed with the second rack 434.

[0041] The second driving motor 44 drives the toggle plate 431 to rotate, and then the toggle plate 431 drives the groove wheel 432 and the moving gear 433 to rotate intermittently, so that the moving gear 433 moves intermittently along the second rack 434, thereby driving the movable mechanism 3 to move intermittently to the right.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 The clamping mechanism 5 includes an elastic telescopic rod 51 fixedly installed on the left side of the slider 313, and the telescopic end of the elastic telescopic rod 51 is fixedly connected to an arc-shaped pressure plate 2 52 on the side close to the axis of the shell 311, and the arc-shaped pressure plate 2 52 is fixedly connected to a guide rod 53 symmetrically distributed on both sides of the width direction of the elastic telescopic rod 51 on the side away from the axis of the shell 311.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9 The drilling mechanism 6 includes a drilling machine 61 fixedly installed on the left side of the slider 313, and wing plates 62 are symmetrically fixedly connected on both sides of the drilling machine 61 in the width direction. A guide hole 63 matching with the guide rod 53 is opened inside the wing plate 62, and the guide rod 53 is parallel to the rotation axis of the drilling machine 61.

[0044] When the slider 313 drives the clamping mechanism 5 and the drilling mechanism 6 to approach the metal bellows 7, the arc-shaped pressure plate 2 52 first contacts the metal bellows 7 and presses on the outside of the metal bellows 7, thereby fixing the metal bellows 7. Then the slider 313 drives the drilling mechanism 6 to continue to approach the metal bellows 7. At this time, the elastic telescopic rod 51 will be compressed, and then the guide holes 63 on both sides of the drilling machine 61 can be fitted onto the guide rod 53. The guide rod 53 is used to limit the drilling machine 61 to ensure the stability of the drilling machine 61 when drilling.

[0045] See also Figure 1 , Figure 2 , Figure 3 and Fig. 9A guide cap 64 which is coaxial with the guide hole 63 is fixedly connected to one side of the wing plate 62 close to the axis of the shell 311 . The guide cap 64 is in a trumpet shape with the small end facing the guide hole 63 . The diameter of the small end of the guide cap 64 is equal to the diameter of the guide hole 63 .

[0046] The guide cap 64 can play a guiding role, making it easier for the wing plate 62 to be fitted onto the outside of the guide rod 53 .

[0047] When used specifically, the following steps are included: Step 1: Place the metal bellows 7 between the two fixing mechanisms 1, and then drive the fixing mechanism 1 to operate through a driving motor 12, so that the claws of the fixing mechanism 1 drive the arc-shaped pressing plate 11 to press the left and right ends of the metal bellows 7, thereby fixing the metal bellows 7.

[0048] Step 2: Start the drilling machine 61 and the driving motor 2 44, and drive the driving motor 2 44 to drive the driving turntable 421 and the dial 431 to rotate. The driving turntable 421 drives the first rack 423 to move up and down through the connecting rod 422, and then the first rack 423 drives the driving gear 324 and the driving rod 323 to rotate forward and reversely, and then the driving rod 323 drives the bevel gear ring 322 and the hollow turntable 321 to rotate through the bevel gear. When the driving rod 323 rotates forward, the hollow turntable 321 drives the slider 313 to approach the metal bellows 7 through the plane thread. When the driving rod 323 rotates reversely, the hollow turntable 321 drives the slider 313 away from the metal bellows 7 through the plane thread.

[0049] Step three: When the slider 313 drives the clamping mechanism 5 and the drilling mechanism 6 to approach the metal bellows 7, the arc pressure plate 2 52 will first contact the metal bellows 7 and press on the metal bellows 7. At this time, the guide rod 53 is just aligned with the guide hole 63. Then the slider 313 continues to drive the elastic telescopic rod 51 and the drilling machine 61 to move toward the direction close to the metal bellows 7. At this time, the elastic telescopic rod 51 will be compressed, and then the guide holes 63 on both sides of the drilling machine 61 will be sleeved on the outside of the guide rod 53. The drilling machine 61 is guided by the guide rod 53 to improve the stability of the drilling machine 61. Then the drilling machine 61 approaches the metal bellows 7 for drilling.

[0050] Step 4: After the drilling is completed, the slider 313 drives the elastic telescopic rod 51 and the drilling machine 61 away from the metal bellows 7. The drilling machine 61 will first drive the wing plate 62 to move away from the metal bellows 7 and fall off from the outside of the guide rod 53. During this process, the elastic telescopic rod 51 will gradually extend. When the elastic telescopic rod 51 returns to its natural extension state, it will drive the arc pressure plate 2 52 to leave the surface of the metal bellows 7.

[0051] Step 5: The groove wheel 432 is driven to rotate intermittently by the toggle plate 431, and then the groove wheel 432 drives the moving gear 433 to rotate intermittently, so that the moving gear 433 moves intermittently to the right along the second rack 434, thereby driving the movable mechanism 3 to move intermittently to the right, so as to facilitate drilling at the next position of the metal bellows 7, and then repeat the above steps until all the holes are drilled on the metal bellows 7.
