[0001] The invention relates to the field of plastic pipe processing equipment, in particular to automatic drilling equipment for engineering plastic pipes based on plastic parts production. Background Art

[0002] With the widespread application of plastic pipes in the fields of construction, chemical industry, electronics and medical treatment, higher and higher requirements are put forward for the processing accuracy and production efficiency of engineering plastic pipes. Most of the existing engineering plastic pipe processing equipment relies on manual feeding, clamping and drilling operations. This traditional processing method is not only labor-intensive, but also easily leads to low processing accuracy and low production efficiency due to the interference of human factors. In addition, manual operation can also cause safety hazards, especially when handling heavy pipes, workers face greater physical burden and potential accidental risks. Although some automated equipment has been gradually put into use, the cost is relatively high, and most of them still fail to solve the problem of insufficient flexibility to adapt to pipes of different specifications, especially in terms of clamping and positioning.

[0019] Working principle: When using this device, first start the first motor to drive the drive shaft to rotate, which further drives the multiple material distribution plates to rotate. At this time, the engineering plastic pipes inside the storage rack roll down from the grooves at the bottom of the storage rack to the feed trough under the action of gravity, and enter the gap between the two material distribution plates through the feed trough. As the material distribution plates rotate, the plastic pipes will be discharged into the support grooves on the top of the storage plates through the discharge trough. At this time, the first electric telescopic rod is started to drive the drive rack to move, and the plastic pipes on the top of the storage plates are moved to the inner side of the clamping assembly, thereby realizing the function of automatic loading.

[0020] At this time, the two-way guide rail is started to drive the two electric slide blocks to move away from or closer to each other, and the two clamping components are close to the two ends of the plastic pipe. After the action is completed, the second electric telescopic rod is started to drive the driving ring to swing. At this time, the swing shaft swings under the action of the positioning shaft, thereby driving multiple clamping wheels to move closer along the center of the driving ring. At this time, multiple second electric telescopic rods contact the outer surface of the plastic pipe and clamp it, so that it can adapt to plastic pipes of different diameters and lengths, so that the equipment has higher flexibility in processing pipes of various specifications. In addition, the third motor is started to drive the driving gear to rotate, and further drive the gear ring to rotate, so as to drive the driving disk to rotate, and further realize the rotation of the clamping component, so that the clamped plastic pipe is turned over, which is convenient for drilling holes at various positions of the plastic pipe, greatly improving the convenience of use of the device;

[0021] During the use of the device, the second motor is started to drive the driving screw to rotate, so that the threaded plate moves along the outer surface of the driving screw, thereby driving the drilling motor and the drill rod to move synchronously. At this time, the drilling motor is started to drive the drill rod to rotate, and the hydraulic cylinder is started to move the drill rod downward to achieve the drilling work of the plastic pipe;

[0022] After the drilling is completed, the output end of the hydraulic cylinder contracts, driving the connecting plate to move upward. In the process of the connecting plate moving upward, the movable shaft is driven to move synchronously. At this time, the rubber piston moves along the inner wall of the mounting cylinder, and the gas inside the mounting cylinder is discharged into the annular tube through the exhaust pipe, and is sprayed on the outer surface of the drill rod through the nozzle on the outer surface of the annular tube, so as to clean the plastic debris adhering to the outer surface of the drill rod, reduce the downtime caused by manual cleaning, and improve production efficiency.

[0023] The present invention provides an automatic drilling device for engineering plastic pipes based on plastic parts production. It has the following beneficial effects:

[0024] 1. The present invention can continuously supply engineering plastic pipes when the equipment is running by adding an automatic feeding component, without manual intervention, significantly improving production efficiency. At the same time, automatic feeding reduces the need for manual handling and placement of pipe fittings, reduces the labor intensity of workers, and reduces the physical burden. At the same time, it also indirectly improves production safety.

[0025] 2. The additional clamping assembly of the present invention can adapt to plastic pipes of different diameters and lengths, so that the device has higher flexibility when processing pipes of various specifications. At the same time, the clamping assembly also has a flipping function, which is convenient for drilling holes at various positions of the plastic pipe, greatly improving the convenience of the device.

[0026] 3. By adding a cleaning component, the present invention can automatically clean the debris on the outer surface of the drilling component during operation, reduce downtime caused by manual cleaning, and improve production efficiency.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides an automatic drilling device for engineering plastic pipes based on plastic parts production, comprising:

[0038] A frame 1, which serves as a support carrier for the entire device, and a top plate 8 is fixedly connected to the top of the frame 1;

[0039] An automatic feeding assembly, which is installed on the top front side of the frame 1 and is used for automatically feeding the plastic pipes;

[0040] The automatic loading assembly includes a storage rack 201, which is fixedly connected to the top front side of the frame 1, and a fixed cylinder 205 is fixedly connected to the outer bottom of the storage rack 201, and the outside of the fixed cylinder 205 is fixedly connected to a first motor 206, and the output end of the first motor 206 is fixedly connected to a driving shaft 209, and the outside of the driving shaft 209 is fixedly connected to a plurality of dividing plates 208, and a feed trough 210 is provided on one side of the outer surface of the fixed cylinder 205, and a discharge trough 207 is provided on the other side of the outer surface of the fixed cylinder 205, and two first electric telescopic rods 202 are fixedly connected to one side of the top of the frame 1, and the output end of the first electric telescopic rod 202 is fixedly connected to the driving frame 203, and the top of the driving frame 203 is fixedly connected to a storage plate 204.

[0041] Specifically, the feed trough 210 is designed as a spacious channel so that the plastic tubes can enter smoothly; and the discharge trough 207 is equipped with a guide structure to ensure the accuracy and smoothness of the plastic tubes during transportation. By starting the first motor 206, the drive shaft 209 is driven to rotate, which further drives the multiple dividing plates 208 to rotate. At this time, the engineering plastic tubes located inside the storage rack 201 roll down from the groove at the bottom of the storage rack 201 into the feed trough 210 under the action of gravity, and enter the gap between the two dividing plates 208 through the feed trough 210. As the dividing plates 208 rotate, the plastic tubes will be discharged into the support grooves on the top of the storage plate 204 through the discharge trough 207. At this time, by starting the first electric telescopic rod 202 to drive the drive frame 203 to move, the plastic tubes on the top of the storage plate 204 are moved to the inner side of the clamping assembly, thereby realizing the function of automatic loading;

[0042] A drilling assembly, which is mounted on the inner side of the top plate 8 and is used for automatically drilling holes in the plastic pipe;

[0043] The drilling assembly includes a second motor 401, which is fixedly connected to the outside of the top plate 8. The output end of the second motor 401 is fixedly connected to a driving screw 402, the external thread of the driving screw 402 is connected to a threaded plate 403, the top of the threaded plate 403 is fixedly connected to a hydraulic cylinder 405, the output end of the hydraulic cylinder 405 is fixedly connected to a connecting plate 408, the bottom of the connecting plate 408 is fixedly connected to a drilling motor 406, and the output end of the drilling motor 406 is fixedly connected to a drill rod 407.

[0044] Specifically, the second motor 401 is the power source of the entire drilling assembly, which is fixedly mounted on the outside of the top plate 8 to ensure the stability of the equipment. The motor has the characteristics of high speed and high torque, and can effectively drive the downstream components to work. The drive screw 402 is made of high-quality alloy material and has good wear resistance and strength. Its external thread design can effectively engage with the threaded plate 403 to ensure stable transmission. The hydraulic cylinder 405 is a key component for generating vertical movement force, and its output end is fixedly connected to a connecting plate 408. The design of the hydraulic cylinder 405 can provide adjustable propulsion, thereby controlling the depth of the drill rod 407 and the accuracy of the drilling.

[0045] A cleaning assembly, which is mounted on the outer surface of the drilling assembly and is used to clean the drilling assembly;

[0046] The cleaning assembly includes two mounting cylinders 501, both of which are fixedly connected to the top of the threaded plate 403, the inside of the mounting cylinder 501 is slidably connected to a rubber piston 503, the outside of the rubber piston 503 is fixedly connected to a movable shaft 502, one side of the outside of the mounting cylinder 501 is connected to an air inlet pipe 504, the other side of the outside of the mounting cylinder 501 is connected to an exhaust pipe 505, both the inside of the air inlet pipe 504 and the exhaust pipe 505 are equipped with a one-way valve, and the other end of the exhaust pipe 505 is fixedly connected to an annular pipe 506. The bottom of the movable shaft 502 passes through the outside of the mounting cylinder 501 and is fixedly connected to the top of the connecting plate 408, and the outer surface of the annular pipe 506 is fixedly connected to a plurality of nozzles.

[0047] Specifically, each mounting tube 501 is slidably connected with a rubber piston 503. The material used for the rubber piston 503 has good elasticity and wear resistance, and can effectively move in the mounting tube 501 to ensure good sealing during the cleaning process. The pressure generated by the movement of the rubber piston 503 can effectively promote the flow of internal gas and enhance the cleaning effect. The outer side of the mounting tube 501 is connected to an air inlet pipe 504, and the other side is connected to an exhaust pipe 505. The air inlet pipe 504 is responsible for introducing compressed air into the interior of the mounting tube 501, while the exhaust pipe 505 discharges the gas generated during the cleaning process. Both pipelines are equipped with a one-way valve to ensure that the gas flows in one direction during the cleaning process to avoid the occurrence of backflow. The design of the annular tube 506 can effectively collect the discharged gas, and spray the gas at a certain pressure through multiple nozzles to achieve the cleaning of the outer surface of the drill pipe 407.

[0048] The output end of the hydraulic cylinder 405 contracts, driving the connecting plate 408 to move upward.

[0050] The clamping assembly includes two support frames 301, and the two support frames 301 are fixedly connected to the top of the electric slider 7.

[0051] Specifically, by starting the second electric telescopic rod 306, the driving ring 307 is driven to swing. At this time, the swing shaft 303 swings under the action of the positioning shaft 304, thereby driving the multiple clamping wheels 305 to move closer along the center of the driving ring 307. At this time, the multiple second electric telescopic rods 306 contact the outer surface of the plastic pipe and clamp it, so that it can adapt to plastic pipes of different diameters and lengths.

[0052] Two bidirectional guide rails 6 are installed at the middle of the top of the frame 1 , and an electric slider 7 is installed outside the bidirectional guide rails 6 .

[0055] Specifically, the guide rod 404 ensures the stability of the threaded plate 403 during its movement.

[0056] A control cabinet 9 is fixedly connected to one side of the top of the frame 1 , and the control cabinet 9 is used to control the driving of the first motor 206 and the second motor 401 .

[0057] Specifically, the control cabinet 9 accurately manages the start, stop, speed adjustment and direction control of the first motor 206 and the second motor 401 through an integrated control system.
