[0048] Embodiment 1

[0049] like Figure 1As shown, the present invention provides a quality inspection device for composite pipes, comprising a workbench 1, a detection component 3 which passes through the workbench 1 at one end and is installed on a cavity provided in the workbench 1, and is used to measure the sealing, inner diameter and inner diameter deviation of the composite pipe, a composite pipe clamp 2 placed directly above the detection component 3, and the composite pipe clamp 2 is used to ensure that the axis of the composite pipe is not offset and can be clamped movable along the Z axis, so as to facilitate the inspection of the composite pipe on the detection component 3, a composite pipe transport component 6 placed on one side of the detection component 3, and a plurality of protruding plates 8 are evenly arranged on the composite pipe transport component 6, which are dedicated to the transport of composite pipes, and the width of the protruding plates 8 is greater than half of the outer diameter of the composite pipe; sensing components 7 are provided on both sides of the composite pipe transport component 6 close to one end of the detection component 3, and are used to detect whether the composite pipe is taken away; a composite pipe placement box 4 is placed outside the other end of the composite pipe transport component 6, and a composite pipe transport device 5 is placed directly above the composite pipe placement box 4.

[0050] Please focus on Figure 2 The detection component 3 includes a dividing plate 301 installed on a cavity provided in the workbench 1, and a composite pipe sealing detection device 302, a composite pipe inner diameter measuring device 303 and a composite pipe inner diameter deviation measuring component 304 are all installed on the dividing plate 301.

[0051] In the prior art, the detection of round pipes is usually to detect their length and circumferential runout. However, composite pipes are commonly used for conveying pipes with corrosive media such as oil and gas or for mine ventilation pipes, so composite pipes need good sealing properties. In order to ensure the accuracy of composite pipe installation, it is necessary to detect the inner diameter deviation of composite pipes. Composite pipes with unqualified deviations will affect the sealing of the joints during the installation of the entire pipeline. Therefore, it is necessary to measure the sealing properties, inner diameter, and inner diameter deviation of composite pipes.

[0052] Please focus on Figure 3 The composite pipe sealing detection device 302 includes a base plate 3021, a cylinder 3023 installed at one end of the base plate 3021, a moving seat 3025 installed on the cylinder 3023, the moving seat 3025 is movably installed on the linear guide rail 3024, a clamping plate 3026 is installed on the moving seat 3025, and the clamping plate 3026 is movably installed on the moving seat 3025 through a universal spherical bearing 30212, and the clamping plate 3026 is installed on the moving seat 3025 through a return spring 3027 and bolts, so as to keep it vertical; a mounting plate 30213 installed at the other end of the base plate 3021, a clamping plate 30211 is movably installed on the mounting plate 30213 through a universal spherical bearing 30212, and the clamping plate 30211 is installed on the mounting plate 30213 through a return spring 3027 and bolts, please focus on Figure 4A gas channel 30215 is provided on the second clamping plate 30211, and the gas channel 30215 is provided with an air inlet and an air outlet 3028, and a gas pipe connector 1 30214 is installed on the air inlet, and a composite pipe support plate 3029 is installed on the base plate 1 3021 and located between the clamping plate 1 3026 and the clamping plate 2 30211.

[0053] The composite pipe is placed on the composite pipe support plate 3029, the cylinder 3023 is turned on, and then the gas is passed through the air pipe joint 30214, so that the composite pipe is filled with gas, which makes it easy to observe the sealing of the composite pipe. The design of the universal spherical bearing 30212 utilizes the floating structure to absorb the vibration of the cross section, and when the gas pressure increases, each return spring 3027 expands and contracts, and the universal spherical bearing 30212 is used as the center to meet the cross section of the workpiece to prevent air leakage. The clamping plate 2 30211 and the clamping plate 1 3026 are usually kept vertical by using four return springs 3027.

[0054] Polyurethane gaskets 30210 are installed on both the second clamping plate 30211 and the first clamping plate 3026, and the gas channel 30215 passes through the polyurethane gasket 30210 on the second clamping plate 30211. The polyurethane gasket 30210 has elastic and soft properties, ensuring the sealing of the contact between the composite tube and the second clamping plate 30211 and the first clamping plate 3026 during inflation.

[0055] When designing the composite pipe sealing detection device 302, the internal pressure of the workpiece should be smaller than the cylinder thrust. To avoid excessive internal pressure of the workpiece, the clamping plate 3026 is pushed, thereby affecting the judgment of the sealing of the workpiece. That is, the test pressure multiplied by the cross-sectional area of ​​the inner diameter of the workpiece is smaller than the operating pressure multiplied by the cross-sectional area of ​​the inner diameter of the round tube.

[0056] Please focus on Figure 5The composite pipe inner diameter measuring device 303 includes a bottom plate 3031, a manual valve 3032 is mounted on one end of the bottom plate 3031, a base 3034 is mounted on the other end of the bottom plate 3031, an inner diameter measuring seat 3033 is mounted on the bottom plate 3031, a plurality of slide rails 3036 are movably mounted on the inner diameter measuring seat 3033, and a moving block 3039 is mounted on the slide rail 3036, and a measuring end 30310 is provided near the axis of the inner diameter measuring seat 3033 of the moving block 3039, a screw rod 3038 is mounted on the slide rail 3036, and a micrometer 3037 is mounted on the micrometer 3037. It is installed on the base 3034, and the sensing end of the micrometer 3037 is in contact with the screw rod 3038, and the flow regulating valve 30311 is installed on the base 3034. The inner diameter measuring seat 3033 is installed with an air pipe joint 2 3035. One end of the air pipe joint 2 3035 is connected to the axis of the inner diameter measuring seat 3033 and a channel is provided on the side of the inner diameter measuring seat 3033 close to the slide rail 3036 along the axis, so as to facilitate pushing the slide rail 3036 after inflation, so that the measuring end 30310 is in contact with the inner wall of the composite pipe, so that the micrometer 3037 can measure the inner diameter of the composite pipe.

[0057] At the same time, the gas switch is adjusted by manual valve 3032.

[0058] Please focus on Figure 6 and Figure 7 The composite pipe inner diameter deviation measuring component 304 includes a fixed seat 3041 installed on the dividing plate 301, a component mounting seat 3043 installed on the fixed seat 3041, a bushing 3044 installed on the component mounting seat 3043, a block 30413 installed on the component mounting seat 3043, a knob plunger 3042, a handle 3045 and a digital micrometer 30412 installed on the block 30413 in sequence, and a limit seat 3046 installed on the bottom surface of the block 30413, a rocking block 30410 movably installed on the limit seat 3046 through a hinge pin 3047, and a probe block 30411 installed on the rocking block 30410 on the side close to the knob plunger 3042.

[0059] Before the operation, the knob plunger 3042 is in the open state, that is, the rocking block 30410 is pushed out to the side close to the digital micrometer 30412. At this time, the dividing plate 301 turns the composite pipe inner diameter deviation measuring assembly 304 to the workpiece, and the workpiece is manually moved along the Z axis so that the probe block 30411 is placed in the composite pipe, and then the knob plunger 3042 is closed. At this time, the probe block 30411 contacts the inner wall of the composite pipe, and finally the digital micrometer records the composite pipe inner diameter deviation.

[0060] When installing the composite pipe inner diameter deviation measuring assembly 304, it is first necessary to determine the measuring reference by measuring the manufactured standard parts, and the front end of the probe block 30411 is in an arc shape, which is very smooth and will not damage the workpiece.

[0061] Please focus on Figure 8 The composite pipe clamp 2 includes a clamp seat 203, a cylinder 5 201 installed at one end of the clamp seat 203, a cam 202 is installed on one end of the cylinder 5 201 passing through the clamp seat 203, the cam 202 is a conical wheel, two clamping rods 205 are hinged to each other through a hinge pin 206, rollers 204 are installed at one end of the clamping rod 205 close to the cam 202, and the rollers 204 are in contact with the cam 202, a screw 208 passes through the clamping rod 205 and both ends of the screw 208 are installed on the clamp seat 203, a clamping block 209 is located outside the two sides of the clamping rod 205 and installed on the screw 208, the clamping block 209 is connected to the clamping rod 205 through a coil spring 1 210 respectively, the hinge pin 206 is installed on a hinge pin fixing seat 207, and the two sides of the hinge pin fixing seat 207 are connected to the clamp seat 203 through a coil spring 211.

[0062] The design of the composite pipe clamp 2 ensures that even if the round pipe is slightly deflected due to manual contact, it will return to its original state under the cooperation of the coil spring 1 210 and the coil spring 2 211 .

[0063] Since the operation in the detection component 3 requires manual debugging for detection, it is easy for the composite pipe to be accidentally touched by humans, resulting in a slight deviation or damage to the composite pipe body. Therefore, a composite pipe clamp 2 suitable for the present detection device is designed to address the above situation. The composite pipe clamp 2 can restore the composite pipe to its initial position and can only move along the Z axis, which is convenient for manual detection of the composite pipe without damaging the composite pipe body.

[0064] Please focus on Figure 1 The sensing assembly 7 includes a mounting rod 701 and a proximity switch 702 mounted on the mounting rod 701 .

The design of the guide block 510 makes it easy to clamp the round tube.

[0068] The composite pipe transport device 5 can transport pipes of different lengths through simple manual adjustment.

[0069] A camera assembly is installed in the composite pipe placement box 4, and the camera assembly is used to determine whether the composite pipe transportation device 5 has clamped the composite pipe.

[0070] Cylinder two 503, cylinder three 505, cylinder four 508, composite pipe transport assembly 6, proximity switch 702, cylinder five 201, indexing plate 301 and cylinder one 3023 are communicatively coupled to the control panel.

[0071] The control panel contains a PLC controller, which can be used to program the numerical control system.

The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0072] Based on the above device, the second embodiment of the present invention further proposes a detection method using the above-mentioned quality detection device for composite pipes, comprising the following steps:

[0073] Step 1: manually take a composite tube and place it on the composite tube clamp 2. If the proximity switch 702 does not detect the composite tube, the composite tube transport assembly 6 is controlled to move forward, and the cylinder 3 505, the cylinder 4 508 and the cylinder 2 503 are simultaneously turned on to clamp the round tube and place it on the composite tube transport assembly 6.

[0074] Step 2: the proximity switch 702 detects the composite pipe, closes the composite pipe transport assembly 6, and simultaneously turns on the cylinder 5 201, which pushes the cam 202 to gradually move the clamping rod 205 away from the composite pipe, and clamps the composite pipe under the action of the coil spring 1 210;

[0076] Step 4: Place the composite pipe on the composite pipe support plate 3029, open the gas cylinder 3023, and then pass gas from the gas pipe connector 30214 to fill the composite pipe with gas. Finally, observe the sealing performance of the composite pipe, and then open the indexing plate 301 to measure the inner diameter of the composite pipe in the next step.

[0077] Step 5: Manually adjust the composite pipe along the Z axis so that the measuring end 30310 is placed inside the composite pipe, open the manual valve 3032, and the gas enters the channel provided in the inner diameter measuring seat 3033 through the flow regulating valve 30311, thereby pushing the moving block 3039 open, so that the measuring end 30310 contacts the inner wall of the composite pipe, so that the micrometer 3037 measures the inner diameter of the composite pipe, and then open the dividing plate 301 to perform the next step of measuring the inner diameter deviation of the composite pipe;
