Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically a straight pipe multi-head drilling machine. Background Technology

[0002] A drilling machine is a device that punches holes in a workpiece. Straight pipe drilling is a common processing method that creates one or more holes on the surface of a straight pipe to facilitate the connection of other structural components or the installation of other parts.

[0003] Currently, when processing straight pipes, four holes need to be drilled in the pipe, requiring four machines for normal production. This results in slow production efficiency, and the use of four machines can lead to processing errors and dimensional defects. Furthermore, drilling machines can usually only drill holes in straight pipes of the same model. When drilling holes in different models of straight pipes is required, the machine needs to be changed, which is very troublesome and costly. Therefore, we propose a multi-head drilling machine for straight pipes. Utility Model Content

[0004] The purpose of this invention is to provide a straight pipe multi-head punching machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-head straight pipe drilling machine, including a drilling machine platform, and further comprising...

[0006] The drilling assembly is installed on the outer wall of the drilling drive plate at the top of the drilling machine body. The drilling assembly includes a cylinder and a drilling head. The drilling head is installed on the cylinder output end on the outer wall of the drilling drive plate.

[0007] A bidirectional lead screw is installed on one side of the body of the drilling machine, and a first motor is installed on the outer wall of the drilling machine at the position of the bidirectional lead screw, with the output end of the first motor fixedly connected to the bidirectional lead screw.

[0008] The feeding guide rail is fixed to the top of the punching machine body between the punching drive plates. A movable seat is threadedly connected to the translation screw inside the feeding guide rail. A second motor is installed at one end of the feeding guide rail. The output end of the second motor is fixedly connected to the translation screw. A first pneumatic clamp and a second pneumatic clamp are respectively installed on both sides of the top of the movable seat.

[0009] The feeding support rods are all fixed to one side of the feeding plate at the top of the drilling machine body.

[0010] Preferably, the bottom end of the drilling drive plate extends into the interior of the drilling machine body and is threadedly connected to a bidirectional lead screw.

[0011] Preferably, there are two sets of feeding support rods, and one end of the feeding support rod is equipped with a limit stop rod by a torsion spring to facilitate the limiting of the straight pipe.

[0012] Preferably, the punching assembly has four sets.

[0013] Preferably, L-shaped supports are installed on the top of the punching machine body on both sides of the feeding guide rail, and spring shock absorbers are installed inside the L-shaped supports to facilitate buffering of the punching drive plate.

[0014] Preferably, the spring shock absorbers are provided in four sets and are symmetrically distributed along the feeding guide rail.

[0015] Preferably, the surface of the feeding support rod is inclined, and the end of the feeding support rod surface near the limiting stop is lower than the end near the feeding plate, so that the straight tube automatically rolls to the limiting stop.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The straight pipe is placed on the feeding support rod. Simultaneously, the drilling drive plate moves towards the straight pipe and pushes it to the center position. The second pneumatic clamp clamps the straight pipe and moves it to the center position of the drilling drive plate. The drilling drive plate moves again and clamps both ends of the straight pipe. The cylinder drives the drilling head to extend and drill holes in the straight pipe. The first pneumatic clamp clamps the straight pipe, and the second pneumatic clamp clamps the next straight pipe. The translation screw drives the movable seat to translate, causing the first pneumatic clamp to remove and release the straight pipe. The second pneumatic clamp moves the straight pipe to the center position of the drilling drive plate. The above steps are repeated to drill holes in the next straight pipe, thus continuously drilling straight pipes. This drilling machine has an optimized structure and can drill four holes simultaneously, which improves production efficiency and ensures product dimensions. Moreover, the distance and size of the holes can be adjusted, and multiple pipe models can be used. Only some parts need to be replaced, and the overall structure does not need to be changed.

[0025] Please see Figure 1-4 One embodiment of this utility model provides: a straight pipe multi-head drilling machine, including a drilling machine platform 1, and further including...

[0026] Drilling assembly 11, all of which are installed on the outer wall of the drilling drive plate 2 at the top of the drilling machine body 1. Drilling assembly 11 includes cylinder 1101 and drilling head 1102. Drilling head 1102 is installed on the output end of cylinder 1101 on the outer wall of drilling drive plate 2.

The output end of the first motor 9 is fixedly connected to the bidirectional lead screw 8.

[0028] Specifically, the straight tube is placed on the feeding support rod 5. Since the surface of the feeding support rod 5 is inclined, the straight tube rolls to the position of the limit stop rod 10. Then, the first motor 9 drives the bidirectional lead screw 8 to rotate, so that the drilling drive plate 2 moves towards the straight tube at the same time and pushes the straight tube to the center position. The drilling drive plate 2 then moves back to its original position.

[0029] Feeding guide rail 3 is fixed at the top of the punching machine body 1 between the punching drive plates 2. The feeding guide rail 3 has a movable seat 13 threadedly connected to the translation screw 16 inside the feeding guide rail 3. A second motor 12 is installed at one end of the feeding guide rail 3. The output end of the second motor 12 is fixedly connected to the translation screw 16. A first pneumatic clamp 14 and a second pneumatic clamp 15 are respectively installed on both sides of the top of the movable seat 13.

[0030] Specifically, the second motor 12 drives the translation screw 16 to rotate, causing the movable seat 13 to move the first pneumatic clamp 14 and the second pneumatic clamp 15. The second pneumatic clamp 15 moves to directly below the straight tube. Then, the first pneumatic clamp 14 and the second pneumatic clamp 15 merge together, and the second pneumatic clamp 15 clamps the straight tube. The second motor 12 drives the translation screw 16 to rotate in the opposite direction, causing the movable seat 13 to move the straight tube to the center position of the drilling drive plate 2 through the second pneumatic clamp 15. The straight tube passes the limit stop 10. After the limit stop 10 releases the straight tube, it returns to its original position under the rebound of the torsion spring. Then, the next straight tube is placed on the loading support rod 5 in preparation.

[0031] Then, the drilling drive plate 2 moves again and clamps both ends of the straight tube. The two ends of the straight tube are located at the center of the four sets of drilling components 11. The cylinder 1101 drives the drilling head 1102 to extend and drill holes in the straight tube. At the same time, the second pneumatic clamp 15 releases the straight tube and moves it to the position of the next straight tube. Then, the first pneumatic clamp 14 clamps the straight tube, and the second pneumatic clamp 15 clamps the next straight tube. The translation screw 16 drives the movable seat 13 to move, so that the first pneumatic clamp 14 moves the straight tube away and releases it. The second pneumatic clamp 15 moves the straight tube to the center position of the drilling drive plate 2. The above steps are repeated to drill holes in the next straight tube.

[0032] The feeding support rod 5 is fixed to one side of the feeding plate 4 at the top of the punching machine body 1;

[0033] The bottom end of the punch drive plate 2 extends into the interior of the punch machine body 1 and is threadedly connected to the bidirectional lead screw 8;

[0034] There are two sets of feeding support rods 5, and one end of the feeding support rod 5 is equipped with a limit stop rod 10 through a torsion spring;

[0035] The punching assembly 11 has four sets in total;

[0036] L-shaped supports 6 are installed on the top of the punching machine body 1 on both sides of the feeding guide rail 3, and spring shock absorbers 7 are installed inside the L-shaped supports 6.

[0037] There are four sets of spring shock absorbers 7, which are symmetrically distributed along the feeding guide rail 3;

[0038] The surface of the feeding support rod 5 is inclined, and the end of the feeding support rod 5 near the limit stop 10 is lower than the end near the feeding plate 4.

[0039] In this embodiment, the following steps are taken: First, the straight tube is placed on the feeding support rod 5. Since the surface of the feeding support rod 5 is inclined, the straight tube rolls to the position of the limit stop rod 10. Second, the first motor 9 drives the bidirectional lead screw 8 to rotate, causing the drilling drive plate 2 to simultaneously move towards the straight tube and push the straight tube to the center position. The drilling drive plate 2 then moves back to its original position. At this time, the second motor 12 drives the translation lead screw 16 to rotate, causing the movable seat 13 to drive the first pneumatic clamp 14 and the second pneumatic clamp. 15. The second pneumatic clamp 15 moves to directly below the straight tube. Then, the first pneumatic clamp 14 and the second pneumatic clamp 15 merge. The second pneumatic clamp 15 clamps the straight tube, and the second motor 12 drives the translation screw 16 to rotate in the opposite direction, so that the movable seat 13 moves the straight tube to the center position of the drilling drive plate 2 through the second pneumatic clamp 15. The straight tube passes the limit stop 10. After the limit stop 10 releases the straight tube, it returns to its original position under the rebound of the torsion spring. Then, the next tube... The straight tube is placed on the feeding support rod 5 for preparation. Then, the drilling drive plate 2 moves horizontally again and clamps both ends of the straight tube. The two ends of the straight tube are located at the center of the four sets of drilling components 11. The cylinder 1101 drives the drilling head 1102 to extend and drill holes in the straight tube. At the same time, the second pneumatic clamp 15 releases the straight tube and moves it to the position of the next straight tube. Then, the first pneumatic clamp 14 clamps the straight tube, the second pneumatic clamp 15 clamps the next straight tube, and the translation screw 16 drives the movable seat 13. The translation causes the first pneumatic clamp 14 to move the straight pipe away and release it. The second pneumatic clamp 15 moves the straight pipe to the center position of the punching drive plate 2. The above steps are repeated to punch the next straight pipe, thus enabling continuous punching of straight pipes. This punching machine has an optimized structure and can punch four holes at the same time, which improves production efficiency and ensures the size of the product. Moreover, the distance and size of the holes can be adjusted, and multiple models of pipes can be used. Only some parts need to be replaced, and the overall structure does not need to be changed.

[0040] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
