Description

Technical Field

[0001] The present invention relates to the technical field of hole punching machines, in particular to a numerically controlled hole punching machine with a self-adjusting function. Background Art

[0002] Domestic aquaculture, gymnasiums, swimming pools and other water treatment products such as large fiberglass filter barrels require fixed installation pipes on their surface during processing. This requires workers to first open holes on the surface of the fiberglass filter barrel, and then insert the installation pipes into the holes for fixed installation.

[0003] The holes on the surface of the existing FRP filter barrel are basically opened by the staff using handheld drilling equipment. The manual drilling process not only generates a lot of noise, but also causes debris to splash everywhere during drilling. Some of the splashed debris will hit the staff, causing serious skin damage to the staff. In addition, the splashed debris will be scattered everywhere and need to be cleaned up by the staff later, which increases the workload of the staff.

[0004] Generally, multiple holes need to be opened on the surface of the fiberglass filter barrel. Before opening the holes, the staff needs to mark the hole positions. However, when using a handheld drilling device, the power head of the drilling device often cannot accurately align with the drilling position, which causes deviations in the drilling position and affects the accuracy of the installation of the installation pipe. Therefore, a CNC hole opening machine with self-adjustment function is proposed to solve the above problem. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1-7 The top of the adjusting assembly is connected with a lifting plate 15, and the top of the lifting plate 15 is provided with a drilling motor 7. The output end of the drilling motor 7 is fixedly connected with an output shaft, and one end of the output shaft is fixedly connected with a driving shaft 11, and one end of the driving shaft 11 is fixedly connected with the power head 22. The surface of the driving shaft 11 is provided with a dust cover 6, which can block debris. At the same time, the inner wall of the dust cover 6 is provided with sound insulation cotton, which can play a good noise blocking role; the surface of the driving shaft 11 is symmetrically fixedly connected with an auxiliary plate 10, and a compression spring 9 is fixedly connected between the auxiliary plate 10 and the dust cover 6. The compression spring 9 can press the dust cover 6 tightly against the surface of the glass fiber reinforced plastic filter barrel to improve the effect of debris blocking and noise blocking;

[0030] A placement platform is provided at the top of the base 1, and a fiberglass filter barrel is placed on the placement platform. An arc-shaped splint 4 symmetrical about the fiberglass filter barrel is provided at the top of the base 1, one of the arc-shaped splints 4 is slidably connected to the base 1, and a rotating opening is provided on the surface of the arc-shaped splint 4. A clamping roller 5 is rotatably connected to the rotating opening through a pin shaft 18, and a limiting component is provided at the top of the arc-shaped splint 4 near the pin shaft 18.

[0031] Further benefits are achieved: the arc-shaped splint 4 cooperates with the clamping roller 5 to clamp and fix the FRP filter barrel, ensuring the stability of the drilling process. The limit assembly cooperates with the clamping roller 5 to rotate the FRP filter barrel without moving the arc plate, making it easy to adjust the drilling position.

[0032] The top of the base 1 is equipped with a first cylinder 2 and a second cylinder 3 . The drive shaft of the output end of the first cylinder 2 is fixedly connected to the mounting plate 8 , and the drive shaft of the output end of the second cylinder 3 is fixedly connected to the arc-shaped clamping plate 4 .

[0033] Further benefits are taken: the first cylinder 2 can push the mounting plate 8 to move, and then push the power head 22 to move, so that the power head 22 contacts the fiberglass filter barrel, and the second cylinder 3 can push the arc plate to move, so that the arc plate can achieve the clamping and fixing function of the fiberglass filter barrel.

[0034] The adjustment assembly includes a bidirectional screw 28 rotatably connected to the inside of the adjustment box, a threaded barrel 29 symmetrically arranged on the surface of the bidirectional screw 28, a transmission rod 30 rotatably connected between the threaded barrel 29 and the lifting plate 15, and a handle that passes through the mounting plate 8 is provided at one end of the bidirectional screw 28.

[0035] Further benefits are achieved by rotating the bidirectional screw 28 through the handle, thereby causing the threaded barrels 29 on both sides to move (toward or in opposite directions), causing the transmission rod 30 to drive the lifting plate 15 to move, thereby achieving the function of adjusting the position of the power head 22.

[0036] A discharge port is provided on the back side of the dust cover 6 near the bottom end, and a plug-in tube is fixedly connected to the discharge port, and a recovery box 19 is plugged into the plug-in tube.

[0037] A further benefit is that under the action of the guide plate 23, the debris can be guided to the discharge port and fall into the recovery box 19 for recycling.

[0038] A notch is provided on the end face of the dust cover 6, in which an elastic membrane 20 is fixedly connected, and a rubber plate 21 is fixedly connected to one end of the elastic membrane 20. A guide plate 23 is hinged at the bottom end of the dust cover 6 near the discharge port, and a return spring 24 is fixedly connected between the guide plate 23 and the inner bottom end of the dust cover 6.

[0039] Further benefits are achieved: the elastic membrane 20 cooperates with the rubber plate 21 so that the end face of the dust cover 6 can better fit the surface of the fiberglass filter barrel, and the guide plate 23 can guide the debris to the discharge port.

[0040] A connecting sleeve 26 is fixedly connected to the inner wall of the power head 22 , a positioning rod 25 is slidably connected inside the connecting sleeve 26 , and a connecting spring 27 is fixedly connected between the positioning rod 25 and the connecting sleeve 26 .

[0041] Take further advantage: the positioning rod 25 can help the staff to quickly align the power head 22 with the drilling point.

[0042] The limiting assembly includes a hinge plate 17 hinged at the top of the arc-shaped splint 4, a fixed plate 13 fixedly connected to the back of the hinge plate 17, a limiting splint 12 slidably connected to one side of the hinge plate 17, and a sliding plate 14 fixedly connected to one end of the limiting splint 12.

[0043] Further benefits are achieved: the limit assembly can control the clamping limit of the pin shaft 18, and then control the clamping limit of the clamping roller 5 on the FRP filter barrel, so that the drilling position of the FRP filter barrel can be adjusted without moving the arc clamping plate 4.

[0044] A clamping spring 16 is fixedly connected between the sliding plate 14 and the fixed plate 13 . One end surface of the limiting clamping plate 12 is inclined. The clamping surface of the limiting clamping plate 12 and the surface of the pin 18 are both provided with anti-slip grooves.

[0045] Further benefits include: the anti-slip grooves can greatly increase the friction between the limiting splint 12 and the pin 18 , thereby improving the limiting effect of the limiting assembly on the pin 18 .

[0046] The drilling motor 7 is a prior art, and its model is KYDAS96300-1E. It can realize the function of driving the output shaft to rotate, and will not be described in detail here.

[0047] The first cylinder 2 and the second cylinder 3 are of the prior art, and their model is MGPM40-125Z-M9NWZ. They can realize the function of driving the mounting plate 8 to move, and will not be described in detail here.

[0048] When the present invention is in use, the FRP filter barrel is placed on the placement table, and the second cylinder 3 is turned on, so that the arc-shaped clamping plate 4 drives the clamping roller 5 to realize the clamping and fixing function of the FRP filter barrel, and then the drilling motor 7 is turned on, so that the drilling motor 7 drives the power head 22 to rotate, and at the same time the first cylinder 2 is turned on, and the first cylinder 2 drives the mounting plate 8 to move, so that the power head 22 is close to the FRP filter barrel. Under the action of the positioning rod 25, it can help the staff to quickly align the power head 22 and the drilling position. When the power head 22 contacts the FRP filter barrel, the dust cover 6 contacts the FRP filter barrel. Under the action of the compression spring 9, the end face of the dust cover 6 is tightly fitted with the FRP filter barrel (the rubber plate 21 and the elastic membrane 20 are elastic, and will deform under pressure so that they can fit with the arc surface of the FRP filter barrel), ensuring the dust cover 6's barrier effect on debris and noise.

[0049] As the power head 22 drills the fiberglass filter barrel, the debris generated by the drilling is blocked inside the dust cover 6 by the action of the dust cover 6, and slides to the discharge port under the action of the guide plate 23, and finally enters the recovery box 19. Most of the noise generated by the drilling is affected by the sound insulation surface inside the dust cover 6, thereby creating a good working environment for the staff and realizing the debris recovery function.

[0050] When the drilling is completed, the positioning rod 25 can push the waste out of the power head 22 under the action of the connecting spring 27, so that the power head 22 can be used again.

[0051] When the drilling position needs to be changed, the hinge plate 17 can be rotated to separate the limiting clamp 12 from the pin 18, so that the clamping roller 5 can rotate freely, thereby allowing the FRP filter barrel to rotate freely. When the position adjustment of the FRP filter barrel is completed, the hinge plate 17 is flipped over again so that the pin 18 is located between the limiting clamps 12, thereby realizing the limiting function of the pin 18 and then the limiting function of the clamping roller 5, ensuring the stability of the FRP filter barrel. Repeating the above operation can realize the drilling function of the FRP filter barrel again, thereby realizing the adjustment function of the drilling position on the surface of the FRP filter barrel without controlling the arc clamp 4 away from the FRP filter barrel, thereby improving the drilling efficiency.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
