Description

Technical Field

[0001] This application relates to the field of pipe processing technology, and in particular to a pipe drilling machine. Background Technology

[0002] Currently, in the production and processing of pipes, it is sometimes necessary to process multiple through holes on the side of the pipe for use. When cutting through holes, a laser drilling machine is generally required. The laser drilling machine includes a clamp and a laser cutting head. The laser cutting head has adjustable movement settings, and the clamp is used to clamp the pipe fed to the laser drilling machine, keeping the pipe stable in the processing position. During the movement, the laser cutting head cuts the outside of the pipe to create multiple through holes on the side of the pipe.

[0003] Regarding the aforementioned technologies, after the through-hole cutting is completed, waste material is generated. The shape of the waste material is mostly consistent with the shape of the formed through-hole, and most of the waste material generated during cutting falls directly into the pipe. Since the pipes are mostly in a horizontal state during processing, after the through-hole on each pipe is processed, personnel need to manually empty the waste material remaining in each pipe. This is especially true for longer pipes, where emptying the waste material is labor-intensive and troublesome. Summary of the Invention

[0004] In order to facilitate the automatic removal of cutting waste from the pipe and reduce labor intensity, this application provides a pipe drilling machine.

[0005] The pipe drilling machine provided in this application adopts the following technical solution:

[0006] A pipe drilling machine includes: an inclined support part with an inclined surface, the inclined support part being located below the pipe processing position; a blocking part located at the lowest side of the inclined surface, the blocking part being used to prevent the pipe from falling off the inclined surface when it slides to the lowest position; a clamping assembly located at the end of the lowest side of the inclined surface, the clamping assembly being used to clamp or release the pipe near the end; and a flipping assembly also located at the end of the lowest side of the inclined surface, the flipping assembly being located above the clamping assembly, the flipping assembly being used to drive the clamping assembly and the pipe to rotate synchronously, with the end of the pipe away from the clamping assembly rotating upwards.

[0007] By adopting the above technical solution, after the pipe is fixed in the processing position of the drilling machine and processed, the loosened pipe falls onto the inclined surface of the inclined support below. At this time, under the action of the pipe's own weight and due to the blocking effect of the blocking part, the pipe slides to the lowest side of the inclined surface. Then, the clamping component can clamp one end of the raised pipe, and then the flipping component drives the clamping component and the pipe to rotate together. As the end of the pipe away from the clamping component is gradually lifted upward, under the action of gravity, the waste pieces remaining in the pipe fall directly out from the lower end of the pipe. Therefore, there is no need to manually empty the waste pieces in each pipe, realizing the effect of automatically emptying the cutting waste pieces in the pipe and reducing labor intensity.

[0008] Preferably, the clamping assembly includes a clamping cylinder and two clamping blocks. The clamping cylinder is provided with two clamping jaws that are close to or far from each other. The clamping jaws are arranged vertically at intervals. The two clamping blocks are fixed to the clamping jaws, and the clamping blocks are located on the upper and lower sides of the pipe.

[0009] By adopting the above technical solution, when the pipe gradually slides down from the inclined surface to the lowest position, one end of the pipe just slides into the space between the two clamping blocks. When the clamping cylinder's jaws move the clamping blocks closer, one end of the pipe can be clamped.

[0010] Preferably, the clamping surfaces of the two clamping blocks are parallel to the inclined surface, and at least one pipe can be clamped between the two clamping blocks.

[0011] By adopting the above technical solution, with the clamping surfaces of the two clamping blocks arranged in parallel, when the two clamping blocks approach and clamp the pipe as the jaws approach, at least one pipe can be clamped more stably, which facilitates the simultaneous clamping and rotation of multiple closely arranged pipes, thereby improving efficiency.

[0012] Preferably, the flipping assembly includes a mounting part and a driving member, the mounting part is rotatably disposed on the inclined support part, the driving member is disposed on the inclined support part and is used to drive the mounting part to rotate, and the clamping assembly is disposed on the mounting part.

[0013] By adopting the above technical solution, the clamping component is set in the mounting part. When the driving component drives the support part to rotate, it can drive the clamping component that clamps the pipe to rotate together.

[0014] Preferably, the mounting part is provided with a shaking component, and the clamping component is disposed on the shaking component; when the mounting part rotates, the shaking component causes the clamping component to shake.

[0015] By adopting the above technical solution, when the pipe is cut through a hole, some burrs may sometimes be generated on the inner wall of the pipe at the position around the cut hole. When one end of the pipe is lifted, some waste pieces will be stuck in the pipe and cannot slide freely out of the pipe. However, by using the shaking component, the pipe and the clamping component can be shaken together, so that the waste pieces in the pipe can fall out more completely.

[0016] Preferably, the shaking component includes an elastic element and a support plate, one end of the elastic element is connected to the mounting portion, the support plate is disposed at the other end of the elastic element away from the mounting portion, and the clamping component is disposed on the support plate.

[0017] By adopting the above technical solution, the support plate and the mounting part are connected by an elastic element. Since the elastic element has a certain elastic deformation capability, and when the gripper cylinder is in the initial position of clamping the pipe, the elastic element is in a stationary state; when the support part rotates at a certain speed, the elastic element also rotates and the direction of force changes, so the support plate may shake, which in turn causes the pipe and the clamping assembly to shake.

[0018] Preferably, the shaking component further includes a vibration motor, which is disposed on the support plate.

[0019] By adopting the above technical solution and setting up a vibration motor, when the clamping component clamps the pipe and drives the pipe to rotate upward, the vibration motor can be directly turned on to shake the support plate, so that the support plate and the rotating pipe vibrate continuously, thereby better emptying the waste pieces stuck in the pipe.

[0020] Preferably, it also includes a conveyor belt located along the length of the lowest side of the inclined surface, and the flipping assembly is located between the end of the conveyor belt and the lowest side of the inclined surface; when the pipe rotates 180 degrees with the flipping mechanism and the clamping assembly releases the pipe, the pipe falls onto the conveyor belt.

[0021] By adopting the above technical solution and setting up a conveyor belt, when the pipe rotates 180 degrees with the flipping mechanism, the pipe leaves the inclined surface. At this time, the clamping component releases the pipe, and the pipe falls onto the conveyor belt, which can then transport the pipe away.

[0022] Preferably, the end of the inclined support located on the lowest side of the inclined surface is provided with a slider for sliding adjustment, and the flipping component is disposed on the slider.

[0023] By adopting the above technical solution, when the position of the slider is adjusted, the positions of the flipping component and the clamping component can be adjusted, thereby adjusting the distance of the clamping component to the lowest end of the inclined surface, which is convenient for clamping the ends of pipes of different lengths.

[0024] Preferably, it also includes a collection bucket located below the flipping assembly.

[0025] By adopting the above technical solution, when the pipe is rotating, the waste material inside the pipe falls out from the lower end during the rotation process and into the collection bucket, which facilitates the collection of waste material.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] (1) By setting the cooperation between the inclined support, the blocking part, the clamping component and the flipping component, the pipe can be rotated, and the waste pieces remaining in the pipe can be poured out from the lower end, so as to facilitate the automatic pouring out of the cutting waste pieces in the pipe and reduce the labor intensity.

[0028] (2) By setting a shaking component, the pipe can shake when it rotates, so that the waste pieces stuck in the pipe by burrs can be poured out better, thus improving the performance.

[0029] (3) By setting a slider, the position of the clamping component can be easily adjusted to clamp the ends of pipes of different lengths. Therefore, when the pipe rotates, the lower end of the pipe is less likely to contact the ground, ensuring the normal rotation of the pipe. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a pipe drilling machine. (Refer to...) Figure 1 The drilling machine includes an inclined support 1, a blocking part 2, a clamping assembly 3, and a flipping assembly 4. The drilling machine also includes a frame 5, a three-jaw clamp 6, and a laser cutting head 7. The three-jaw clamp 6 is mounted on the frame 5 and used to clamp the pipe at the processing station. The laser cutting head 7 is slidably connected to the frame 5 and moves along the length of the pipe located above the processing station to cut several through holes on the outside of the pipe.

[0036] The inclined support 1 is fixed to the frame 5. An inclined surface 8 is machined on the upper side of the inclined support 1. The inclined surface 8 is rectangular. The inclined support 1 is located below the pipe processing position, and the higher side of the inclined surface 8 is directly below the pipe at the processing position. The blocking part 2 includes several vertically arranged vertical rods 21. The lower end of the vertical rods 21 is fixed to the lowest side of the inclined surface 8. Each vertical rod 21 is spaced apart along the length direction of the lowest side of the inclined surface 8. After the pipe is drilled, the three-jaw clamp 6 opens and releases the pipe. At this time, the pipe falls and slides down from the higher position of the inclined surface 8 to the lowest position under the action of its own weight. The blocking part 2 can prevent the pipe from falling off the inclined surface 8 when it slides to the lowest position of the inclined surface 8, so that after each pipe falls onto the inclined surface 8, it can be arranged closely together on the inclined surface 8.

[0037] The clamping component 3 is disposed on the inclined support part 1, and the clamping component 3 is located at the end of the lowest side of the inclined surface 8. The clamping component 3 is used to clamp or release the pipes arranged on the inclined surface 8, and the clamping component 3 clamps the pipes near the end.

[0038] Specifically, refer to Figure 1 and Figure 2 The clamping assembly 3 includes a clamping cylinder 31 and two clamping blocks 32. The clamping cylinder 31 is horizontally arranged, and two clamping claws that are close to or far from each other are installed on the clamping cylinder 31. The clamping claws are arranged vertically at intervals. The two clamping blocks 32 are fixed to the clamping claws, and the two clamping blocks 32 are located on the upper and lower sides of the pipe, so that when the pipe slides down from the inclined surface 8, the end of the pipe can slide into the space between the two clamping blocks 32, which facilitates the clamping of the clamping blocks 32.

[0039] In some embodiments, the opposite sides of the two clamping blocks 32 are clamping surfaces, and the clamping surfaces of both clamping blocks 32 are parallel to the inclined surface 8. The clamping surface of the lower clamping block 32 is slightly lower than the inclined surface 8, and the clamping surface of the upper clamping block 32 is also lower. At least one pipe can be clamped between the two clamping blocks 32. Therefore, when the two clamping blocks 32 are close to clamp the pipe, multiple pipes can be clamped more smoothly at the same time, so as to flip multiple pipes at the same time and improve efficiency.

[0040] Reference Figure 1 and Figure 3The flipping component 4 is also located at the end of the lowest side of the inclined surface 8. The clamping component 3 is located on the flipping component 4. The flipping component 4 is used to drive the clamping component 3 and the clamped pipe to rotate synchronously. When the pipe rotates with the clamping component 3, the end of the pipe away from the clamping component 3 rotates upward. When the pipe gradually rotates to a vertical state, the waste material pieces cut off inside the pipe can fall out from the lower end of the pipe, thus achieving the effect of automatically emptying the waste material pieces remaining inside the pipe.

[0041] The flipping assembly 4 includes a mounting part 41 and a driving member 42. The mounting part 41 is rotatably mounted on the inclined support part 1. The mounting part 41 is plate-shaped, and its rotation axis is horizontal. The driving member 42 is fixed to the inclined support part 1 and is used to drive the mounting part 41 to rotate. The clamping assembly 3 is disposed on the upper surface of the mounting part 41. The driving member 42 is selected as either a servo motor or a rotary cylinder. In this embodiment, the driving member 42 is selected as a servo motor. When the servo motor drives the mounting part 41 to rotate, it can drive the mounting part 41 and the entire clamping assembly 3 to rotate.

[0042] Reference Figure 1 and Figure 2 In some embodiments, after the pipe is cut to create a through hole, burrs may sometimes be generated on the inner wall of the pipe around the through hole. This can cause scrap pieces to become stuck inside the pipe when they slide out, preventing them from falling out freely. Therefore, a shaking component 9 is provided on the mounting part 41, and a clamping component 3 is disposed on the shaking component 9. When the mounting part 41 rotates, the shaking component 9 drives the clamping component 3 to shake, which in turn causes the rotating pipe and the clamping component 3 to shake together. This allows the scrap pieces inside the pipe to be freed from the obstruction of the burrs, ensuring that the scrap pieces inside the pipe can fall out more completely.

[0043] Specifically, the shaking component 9 includes an elastic element 91 and a support plate 92. The elastic element 91 is selected as a spring or a rubber column. In this embodiment, the elastic element 91 is selected as a spring. Two springs are vertically arranged and spaced apart. The lower end of the spring is connected to the upper surface of the mounting part 41. The support plate 92 fixes the upper end of the spring and is parallel to the mounting part 41. The clamping component 3 is positioned on the upper surface of the support plate 92. Before the mounting part 41 rotates, the clamping component 3 is in the initial state, at which time the spring is in a state of axial compression. When the clamping component 3 clamps the pipe and rotates with the mounting part 41 at a certain speed, the spring changes from a vertical state to an inclined state. The support plate 92 and the clamping component 3 connected to the spring generate a component force on the spring that deviates from the spring axis, causing the spring to deviate on its own axis. The spring's restoring force will drive the spring to deviate in the reset direction. Therefore, the support plate 92, the clamping component 3, and the pipe clamped by the clamping component 3 will shake, thereby causing the scrap piece stuck by the burr to slip off.

[0044] In some embodiments, the shaking component 9 further includes a vibration motor 93, which is disposed on the lower surface of the support plate 92 to better ensure that the pipe vibrates during rotation so that the waste material inside the pipe completely falls off.

[0045] In some embodiments, a conveyor belt 10 is provided on the side of the flipping assembly 4 away from the inclined surface 8. The conveyor belt 10 includes a frame 101 and a conveyor belt 102 rotatably wound around the frame 101. Rollers 11 are installed at the bottom of the frame 101 to facilitate the movement of the conveyor belt 10. The conveying surface of the conveyor belt 102 is horizontally arranged and lower than the lowest side of the inclined surface 8. The conveyor belt 10 is located in the length direction of the lowest side of the inclined surface 8, and the flipping assembly 4 is located between the end of the conveyor belt 10 and the lowest side of the inclined surface 8. When the pipe rotates 180 degrees with the flipping mechanism, the pipe rotates from the horizontal position to another lower horizontal position and is located directly above the conveyor belt 102. At this time, the clamping assembly 3 releases the pipe, and the pipe falls onto the conveyor belt 10.

[0046] In some embodiments, a slider 12 is slidably adjusted at the end of the inclined support 1 located on the lowest side of the inclined surface 8. The slider 12 slides along the length direction parallel to the lowest side of the inclined surface 8, and the flipping assembly 4 is disposed on the slider 12. A groove 13 is formed on the inclined support 1, which is parallel to the length direction of the lowest side of the inclined surface 8, and the slider 12 slides in the groove 13. A screw 14 is horizontally and rotatably disposed on the inclined support 1, but the screw 14 is relatively stationary with respect to the inclined support 1. The screw 14 is threaded through the slider 12 and is disposed along the length direction parallel to the lowest side of the inclined surface 8. When the screw 14 is rotated, the slider 12 can be adjusted, thereby adjusting the distance of the clamping assembly 3 located at the lowest side of the inclined surface 8, which is convenient for clamping the ends of pipes of different lengths.

[0047] In some embodiments, a collection bin 15 is provided below the flipping assembly 4 and the slider 12. The collection bin 15 has an opening at its upper end, and the opening of the collection bin 15 is always located below the end of the tube gripped by the clamping assembly 3. When the waste sheet falls out from the end of the tube, the waste sheet falls directly into the collection bin 15 for easy collection.

[0048] The implementation principle of a pipe drilling machine according to an embodiment of this application is as follows: After the through hole of the pipe is processed, the pipe is first dropped to a higher position on the inclined surface 8, and then slides down towards a lower position on the inclined surface 8, so that the pipe is away from directly below the laser cutting head 7, and the cutting of the next pipe can continue. When the pipe slides down to the lowest position on the inclined surface 8, it is blocked by the blocking part 2, so that the processed pipes are arranged close together on the inclined surface 8. Moreover, at least one end of the pipe enters between the two clamping blocks 32, and then the clamping cylinder 31 drives the two clamping blocks 32 to clamp one end of the pipe; finally, the driving component 42 drives the clamping assembly 3 and the pipe clamped by the clamping assembly 3 to start rotating. When the pipe is rotated 180 degrees, the pipe will go from a horizontal position through a vertical position and then back to a lower horizontal position. During this process, the waste pieces remaining in the pipe can fall off from the end of the pipe that is clamped by the clamping block 32 under the action of gravity. Finally, the clamping block 32 releases the pipe, and the pipe falls onto the conveyor belt 10 and is transported away from the conveyor belt 10. Therefore, there is no need to manually empty the waste pieces in each pipe, which realizes the effect of automatically emptying the cutting waste pieces in the pipe and reducing labor intensity.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
