Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and specifically relates to a numerical control machine tool capable of automatically feeding pipes. Background Technique

[0002] As is well known, at present, due to the simple, convenient and fast processing, manufacturing, construction and installation processes of round pipes, they have become an important component of building structural systems and are thus widely used in various fields of national economic construction. Round pipes can be used for pipelines, thermal equipment, mechanical industry, oil and geological drilling, containers, chemical industry and special purposes. In particular, round steel pipes are widely used in our industrial production.

[0003] When a numerical control machine tool drills holes in a round pipe, first, the operator needs to clamp the round pipe onto a fixture, and then move the round pipe to the processing area below the machine head through the fixture for drilling. After drilling is completed, the round pipe is again brought to the front end of the machine tool through the fixture, and the fixture releases the round pipe. Then the operator takes away the processed round pipe. However, when the operator manually fixes the round pipe on the fixture, they need to reach their hand into the machine tool. When the fixture clamps the round pipe, sometimes the operator may accidentally hold their hand near the two ends of the round pipe. Thus, when the fixture clamps the round pipe and the operator supports the round pipe, the fixture may clamp the operator's hand. And if the round pipe is heavy, it may be strenuous for the operator to pick up the round pipe with both hands. For this reason, we propose a numerical control machine tool capable of automatically feeding pipes. Summary of the Invention

And after the processing is completed, the round tube is automatically oriented by the tube clamping mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-8 , the present invention provides a technical solution: Embodiment 1, a numerically controlled machine tool capable of automatically feeding pipes, including: a numerically controlled machine tool main body 1;

[0032] A pipe clamping mechanism 2 is arranged on the numerically controlled machine tool main body 1, and the pipe clamping mechanism 2 is used for clamping and moving the round pipe;

[0033] A pipe feeding mechanism 3 is fixedly arranged on one side of the numerically controlled machine tool main body 1, and the pipe feeding mechanism 3 is used for pushing the round pipe into the pipe clamping mechanism 2;

[0034] A detection component 4 is fixedly arranged on the inner wall of the numerically controlled machine tool main body 1, and the detection component 4 is used for controlling the operation of the pipe feeding mechanism 3;

[0035] A pipe control component 5 is movably arranged on the pipe feeding mechanism 3. There are two pipe control components 5. The pipe control component 5 is used to block the round pipe on the pipe feeding mechanism 3 from entering the pipe clamping mechanism 2. When the numerically controlled machine tool drills the round pipe, first, the staff needs to clamp the round pipe on the fixture, and then move the round pipe to the processing area under the machine head through the fixture for drilling. Then, after the drilling is completed, the round pipe is brought to the front end of the machine tool again through the fixture, and the fixture releases the round pipe. The staff then takes away the processed round pipe. However, when the staff manually fixes the round pipe on the fixture, they need to reach their hands into the machine tool. When the fixture clamps the round pipe, sometimes the staff may accidentally hold their hands near both ends of the round pipe. Thus, when the fixture clamps the round pipe and the staff supports the round pipe, the fixture may clamp the staff's hand. And if the round pipe is heavy, it may be difficult for the staff to pick up the round pipe with both hands. Therefore, a pipe feeding mechanism 3 is installed on one side of the numerically controlled machine tool main body 1. The staff first puts a large number of round pipes to be processed together, and then through the operation of the pipe feeding mechanism 3, the round pipes are conveyed into the pipe clamping mechanism 2 one by one. Then, through the rotation of the driving lead screw on the numerically controlled machine tool main body 1, the pipe clamping mechanism 2 and the round pipe are accurately moved to the processing area. And after the processing is completed, the round pipe is automatically turned by the pipe clamping mechanism 2.

[0036] The pipe clamping mechanism 2 includes a main support plate 21 threadedly connected to the driving lead screw on the main body 1 of the numerically controlled machine tool. On one side of the main support plate 21, two symmetrically arranged pipe clamping bodies 22 are fixedly provided. An upper pipe orifice 24 is provided directly between the two pipe clamping bodies 22, and the depth dimension of the upper pipe orifice 24 gradually deepens from both sides towards the center.

[0037] Below the main support plate 21, a bottom plate 23 fixedly connected to the main body 1 of the numerically controlled machine tool is provided. A rectangular hollow opening is formed inside the bottom plate 23. A fixed inclined plate 25 is fixedly provided on the lower wall of the bottom plate 23. On the other side of the fixed inclined plate 25, a detection inclined plate 26 rotatably connected to the bottom plate 23 is provided. The center lines of the detection inclined plate 26 and the fixed inclined plate 25 are aligned with the center line of the rectangular hollow opening. After the pipe feeding mechanism 3 places a round pipe between the two pipe clamping bodies 22, the two pipe clamping bodies 22 simultaneously drive the hat-shaped clamping arms to clamp the round pipe. Then, the motor drives the lead screw to rotate, and the rotation of the lead screw drives the main support plate 21 to move to the processing area. After the drilling is completed, the rotation of the lead screw drives the main support plate 21 to move to the other end of the main body 1 of the numerically controlled machine tool again. Then, the two pipe clamping bodies 22 rotate 90 degrees to release the round pipe. The processed round pipe falls from the upper pipe orifice 24 into the hollow opening inside the bottom plate 23, and the round pipe hits the fixed inclined plate 25 and the detection inclined plate 26. The gravity of the round pipe can cause the detection inclined plate 26 to rotate and open, and then the round pipe can fall out of the machine tool. Torsion springs are provided on the rotating columns at both ends of the detection inclined plate 26, which can drive the detection inclined plate 26 to abut against the fixed inclined plate 25.

[0038] According to the above embodiment, Embodiment 2, on the other side of the detection inclined plate 26, a push top plate 27 is fixedly provided. A touch pad 29 is fixedly provided on the push top plate 27. Above the touch pad 29, an induction delay switch 28 fixedly connected to the bottom plate 23 is provided. The included angle between the push top plate 27 and the detection inclined plate 26 is 125°. On the basis of Embodiment 1, the induction delay switch 28 is installed. The induction delay switch 28 can be connected to the pipe feeding mechanism 3 to control the operation of the pipe feeding mechanism 3. When the round pipe falls and the detection inclined plate 26 rotates and opens, the push top plate 27 is driven by the detection inclined plate 26 to rotate upward, and the touch pad 29 contacts the induction delay switch 28, thereby controlling the pipe feeding mechanism 3 to work and send the next round pipe into the pipe clamping mechanism 2.

[0039] The pipe feeding mechanism 3 includes a pre-storage box 31. Inside the pre-storage box 31, a partition plate 32 is fixedly provided. A pipe feeding orifice 33 is formed inside the partition plate 32. On the other side of the pipe feeding orifice 33, a number of lifting support plates 34 and temporary storage support plates 35 are provided. The lifting support plates 34 and the temporary storage support plates 35 are alternately distributed, and the temporary storage support plates 35 are in contact with the rear wall of the pre-storage box 31.

[0040] Two symmetrically arranged rolling guide plates 36 are fixedly provided on the top rear wall of the temporary storage pallet 35. A number of equally spaced and evenly distributed limiting strip plates 37 are fixedly provided on the upper walls of the rolling guide plates 36. The two rolling guide plates 36 form an eight-shaped configuration. First, a large number of round tubes can be placed in the pre-storage box 31. Then, the electric push rod drives the lifting pallet 34 to rise onto the temporary storage pallet 35 on the next higher step of itself. Therefore, the round tubes roll from the feeding pipe orifice 33 onto the lifting pallet 34. Then, the lifting pallet 34 lifts the round tubes onto the temporary storage pallet 35. By analogy, the round tubes can roll onto the rolling guide plates 36. At the same time, the limiting strip plates 37 on the rolling guide plates 36 can make the round tubes rolling towards the pipe clamping mechanism 2 roll in parallel.

[0041] According to the above embodiment, Embodiment Three, the detection assembly 4 includes a mounting box 41 fixedly connected to the main body 1 of the numerically controlled machine tool. A telescopic groove 42 is formed inside the mounting box 41. A bottom groove 43 is formed in the bottom wall of the telescopic groove 42. The telescopic groove 42 is aligned with the pipe clamping mechanism 2.

[0042] A water column pipe 44 is rotatably arranged inside the bottom groove 43. Conductive bodies 45 are fixedly provided at both the upper and lower ends of the inner wall of the water column pipe 44. The water volume in the water column pipe 44 is less than one-half of the volume of the water column pipe 44. One detection assembly 4 is installed. The water column pipe 44 is made of insulating plastic material and can be used in conjunction with Embodiment One. The two wires of the water column pipe 44 in the detection assembly 4 are connected in series with the pipe feeding mechanism 3. When the round tube processing is completed and the main pallet 21 moves forward into the mounting box 41, the vertical water column pipe 44 can be pushed into the bottom groove 43 through the main pallet 21. Then, the water in the water column pipe 44 flows to the other end of the water column pipe 44. The two conductive bodies 45 are energized through the water, thereby controlling the pipe feeding mechanism 3 to work and continue to feed pipes. It can also be connected in series with the induction delay switch 28 and the pipe feeding mechanism 3 in Embodiment Two. In this way, only after the processed round tube is placed and the main pallet 21 moves forward to the end, the pipe feeding mechanism 3 continues to feed pipes.

[0043] The pipe control assembly 5 includes a pipe blocking plate 51 movably connected to the pipe feeding mechanism 3. A first magnet 52 is fixedly provided at the bottom of the pipe blocking plate 51. The lower wall of the first magnet 52 is of an inclined structure.

[0044] A force-bearing plate 53 is arranged below the first magnetic block 52. Two second magnetic blocks 54 with opposite magnetic polarities are inlaid on the upper wall at one end of the force-bearing plate 53. A return spring 55 is fixedly arranged on the rear wall of the second magnetic block 54. The other end of the force-bearing plate 53 is of a triangular structure. When the pipe clamping body 22 rotates to align with the rolling guide plate 36, the force-bearing plate 53 is squeezed by the clamping arm of the pipe clamping body 22, so that the force-bearing plate 53 retracts into the rolling guide plate 36. At the same time, due to the attraction of the latter second magnetic block 54, the pipe blocking plate 51 retracts downward. Then the round pipe can roll into the pipe clamping body 22. And when the clamping arm of the pipe clamping body 22 does not squeeze the force-bearing plate 53, due to the repulsion of the former second magnetic block 54, the pipe blocking plate 51 rises to block the round pipe about to roll.

Moreover, the terms "include", "comprise" or any other variant thereof are 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 further includes elements inherent to such process, method, article or device.
