In order to ensure the quality of drilling, it is necessary to first drill a reserved hole on the end face of the glass fiber reinforced plastic pipe.

[0047] There are two groups of fixing components, which are located on both sides of the installation sleeve 20. The fixing components include a connecting frame 24 fixed on the installation sleeve 20, and a push rod 25 is threadedly connected to the connecting frame 24. A splint 26 is connected to a bearing on the side of the push rod 25 close to the installation sleeve 20, and a slide bar 27 is fixed below the splint 26.

When the glass fiber reinforced plastic pipe is placed in the installation sleeve 20, the push rod 25 is rotated to control the splint 26 to clamp the surface of the glass fiber reinforced plastic pipe, thereby fixing the glass fiber reinforced plastic pipe.

[0048] The propulsion assembly includes an eighth drive 21 fixed in the mounting sleeve 20, three groups of ninth drives 22 are fixed to the output end of the eighth drive 21, and a top plate 23 is fixed to the output end of the ninth drive 22. When the FRP pipe is fixed, the ninth drive 22 is started to extend so that the top plate 23 contacts the inner wall of the FRP pipe.

[0049] A pressure sensor 38 is fixed to the top plate 23 near the inner wall of the glass fiber reinforced plastic pipe. The pressure sensor 38 is used to detect the pressure of the top plate 23 on the inner wall of the glass fiber reinforced plastic pipe.

[0050] A baffle plate 36 is fixed to one side of the rotating rod 34 , and two sets of side plates 35 are fixed to the bottom of the slide plate 7 . The rotation angle of the rotating rod 34 is limited by the cooperation between the baffle plate 36 and the side plates 35 .

[0051] It should be noted that the seventh drive 19 may be a motor;

[0052] The eighth drive 21 and the ninth drive 22 may be electric telescopic rods.

[0053] A precise positioning and punching device for glass fiber reinforced plastic pipes also includes a punching positioning control system, the punching positioning control system includes a data receiving module and a processing module, the data receiving module includes a pressure receiving submodule, an image receiving submodule and a logic judgment submodule, the pressure receiving submodule is electrically connected to the pressure sensor 38, and the image receiving submodule is electrically connected to the camera 37;

[0054] The image receiving submodule includes a size recognition unit;

[0055] The processing module includes a punching adjustment submodule, a marking submodule and a warning submodule. The punching adjustment submodule is electrically connected to the first driver 3 .

[0056] The punching positioning control system includes the following specific steps:

[0057] Step 1: After fixing the FRP pipe with the fixing assembly, start the pushing assembly to squeeze the inside of the FRP pipe, and ensure the stability of the FRP pipe by clamping it inside and outside;

[0058] Specifically, the staff sets the maximum threshold value of the top plate 23 squeezing the glass fiber reinforced plastic pipe in the pressure receiving submodule. When the top plate 23 squeezes the inner wall of the glass fiber reinforced plastic pipe, the pressure detected by the pressure sensor 38 in real time is , and transmit the signal to the pressure receiving submodule. When the ninth drive 22 is stopped, the operation is stopped to avoid excessive extrusion pressure, which may cause deformation of the glass fiber reinforced plastic pipe. In this step, the glass fiber reinforced plastic pipe is fixed by the cooperation of the pushing component and the fixing component.

[0059] Step 2: After the FRP pipe is clamped, the end face of the FRP pipe is photographed by the camera 37 to determine whether the FRP pipe is deformed when being squeezed by the top plate 23 and to determine the rigidity of the FRP pipe;

[0060] Specifically, the camera 37 transmits the captured image to the image receiving submodule, and the diameter of the end face of the glass fiber reinforced plastic pipe is identified by the size recognition unit. Since the normal diameter of the FRP pipe end face is set in the image receiving submodule as ,when When , it means that the end face shape of the FRP pipe has not changed, proving that the FRP pipe has good rigidity. , indicating that the shape of the end face of the corrugated steel pipe has changed, proving that the rigidity of the FRP pipe is poor. The FRP pipe with poor rigidity is removed and no subsequent drilling work is performed.

[0061] Step 3: After determining the rigidity of the FRP pipe, start punching the reserved holes on the FRP pipe;

[0062] Specifically, the flip assembly is started to move the second drill bit 12 to the top of the end face of the FRP pipe, and the second drive 6 is controlled to start and drive the second drill bit 12 to move downward to perform reserved hole processing on the end face of the FRP pipe. When the first reserved hole processing is completed, the second drill bit 12 is controlled to be lifted, and the FRP pipe is driven to rotate a certain angle through the seventh drive 19, so that the next drilling position is rotated to the bottom of the second drill bit 12, and drilling continues:

[0063] It should be noted that the rotation angle of the FRP pipe is set by the program, so I will not go into details here.

[0064] The reserved holes previously drilled will be rotated to the bottom of the detection component, and the quality of the reserved holes will be detected by the detection component to further judge the quality of the FRP pipe;

[0065] Specifically, the top plate 23 is controlled to extend so that the extrusion plate 32 enters the inside of the reserved hole, and the sixth drive 31 is simultaneously started to extend so that the extrusion plates 32 on both sides rotate around the cylindrical head 33. Therefore, the two groups of extrusion plates 32 inside the reserved hole will move toward the inner wall close to the reserved hole, thereby applying pressure to the inner wall of the reserved hole. At this time, the camera 37 is started to take a picture of the reserved hole and transmit it to the image receiving submodule to determine whether the reserved hole will change. When the reserved hole is subjected to pressure, the reserved hole is deformed. At this time, the size recognition unit analyzes the distance between the edge of the reserved hole and the inner wall of the glass fiber reinforced plastic pipe (such as Fig.11 As shown in the figure), the distance between the edge of the reserved hole and the inner wall of the FRP pipe is set to , and the distance between the edge of the reserved hole and the inner wall of the FRP pipe after deformation is ,when When the reserved hole is not deformed when subjected to pressure, , where a represents the maximum range threshold of the reserved hole deformation, indicating that the deformation of the reserved hole is within the range. When the reserved hole is outside the allowable deformation range, it means that there is a problem with the quality of the steel pipe end surface. At this time, the signal is transmitted to the alarm submodule to alarm and inform the staff;

[0066] Since the push assembly is always against the inner wall of the FRP pipe during drilling, in order to further ensure the accuracy of the drilling position, it is necessary to further check whether the deformation of the reserved hole is caused by the top plate 23 being against the inner wall of the FRP pipe for a long time. Therefore, when the deformation of the reserved hole is within the range, the change of the end diameter of the FRP pipe in step 2 is repeated. This indicates that the diameter of the inner wall of the FRP pipe has not changed after being squeezed for a long time. When , it means that the inner wall of the FRP pipe has changed in diameter after being squeezed for a long time, indicating that the rigidity of the FRP pipe has affected the position of the reserved hole, and the signal is transmitted to the alarm submodule at this time;

[0067] When the deformation of the reserved hole is within the range and the diameter of the inner wall of the FRP pipe does not change after being squeezed for a long time, it means that the reserved hole can continue to be processed, and the signal is transmitted to the marking submodule for marking (named as marking hole), so as to adjust the distance between the punching mechanism and the reserved hole during subsequent hole processing.

[0068] Through the above steps, the quality of the glass fiber reinforced plastic pipe can be judged according to the shape change of the reserved hole when processing the reserved hole, thereby improving the accuracy of the punching positioning.

[0069] It should be noted that when detecting the deformation of the reserved hole, the second drill bit 12 can continue to process the reserved hole at other positions of the end face of the glass fiber reinforced plastic pipe, and the two can be performed simultaneously to ensure processing efficiency.

[0070] Step 4: After the reserved hole is processed, the reserved hole is processed into a finished hole;

[0071] Specifically, after all the reserved holes are processed, a signal is transmitted to the flip assembly to control the first drill bit 13 to rotate to the top of the reserved holes to start processing the reserved holes;

[0072] When the marking hole is processed, the signal is transmitted to the punching adjustment submodule to control the first drive 3 to drive the punching mechanism to move. The moving distance is within the range of a, so that the first drill bit 13 is aligned with the marking hole, and processing is performed when the reserved hole is deformed and within the range. This step can adjust the processing position according to the state of the reserved hole, further realize accurate positioning and punching, and ensure the quality of punching.
