[0027] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] As Figure 1 、 Figure 2 shown, a detection device for processing PP pipe fittings includes a detection table 1, and a feeder 11 and a fixing plate 12 are installed on the top surface of the detection table 1. A rotating rod 14 is rotatably installed on the side surface of the fixing plate 12, and a rotating circular plate 13 is sleeved and fixed on the outer peripheral surface of the rotating rod 14. A driving motor 15 is fixed on the fixing plate 12, and the output end of the driving motor 15 is fixedly connected to the end of the rotating rod 14.

[0029] As Figure 2 、 Figure 3 shown, four groups of detection components 2 are arranged on the side surface of the rotating circular plate 13 close to the feeder 11, and the four groups of detection components 2 are arranged at equal intervals along the circumferential direction of the rotating circular plate 13. The detection component 2 includes three horizontally arranged positioning circular rods 21 and a measuring rod 22 located in the middle of the three positioning circular rods 21. The outer peripheral surface of the positioning circular rod 21 can be attached to the outer peripheral surface of the pipe fitting, and the measuring rod 22 can pass through the pipe fitting. A number of thickness detection components 3 for detecting the wall thickness of the pipe fitting are arranged on the outer peripheral surface of the measuring rod 22, and the number of thickness detection components 3 are arranged at equal intervals along the length direction of the measuring rod 22.

[0030] As Figure 2 、 Figure 3 、 Figure 4 shown, the thickness detection component 3 includes two first moving blocks 31 and two second moving blocks 4. The first moving blocks 31 and the second moving blocks 4 are arranged at intervals along the circumferential direction of the measuring rod 22. A first contact groove 33 is formed on the side surface of the first moving block 31 away from the measuring rod 22, and a first contact block 32 is slidably installed on the first moving block 31 along the radial direction of the measuring rod 22 through the first contact groove 33. A contact head 48 is fixed on the side surface of the first contact block 32 away from the measuring rod 22, and the contact head 48 can abut against the inner peripheral surface of the pipe fitting. Limit blocks 34 are fixed on both sides of the first contact block 32, a limit groove 35 is formed on the side surface of the first contact groove 33, and the limit blocks 34 are slidably matched with the first moving block 31 along the radial direction of the measuring rod 22 through the limit groove 35. A limit spring 36 is fixed on the side surface of the limit block 34 close to the measuring rod 22, and one end of the limit spring 36 away from the limit block 34 is fixedly connected to the inner wall of the limit groove 35. A first fixed contact 37 is embedded and fixed on the inner wall of the limit groove 35, and the limit block 34 can be in electrical contact with the first fixed contact 37. A first warning bell 38 is arranged on the rotating circular plate 13, the first fixed contact 37 is electrically connected to a power source, and the limit block 34 is electrically connected to the first warning bell 38.

[0031] When the pipe fitting enters between the three positioning round rods 21, the outer peripheral surface of the pipe fitting fits with the outer peripheral surfaces of the positioning round rods 21, thereby limiting the pipe fitting. At the same time, the measuring rod 22 passes through the middle of the pipe fitting, and the contact head 48 fits with the inner wall of the pipe fitting under the elastic force of the limiting spring 36. When the wall thickness of the pipe fitting is equal to or less than the standard size, the limiting block 34 does not move, and the limiting block 34 remains separated from the fixed contact piece one 37; when the wall thickness of the pipe fitting is greater than the standard size, the contact head 48 moves towards the direction close to the measuring rod 22 under the abutting action of the pipe fitting, the limiting block 34 is in electrical contact with the fixed contact piece one 37, and the warning bell one 38 is powered on to work, thereby reminding the staff.

[0032] As Figure 3 、 Figure 4 shown, a plurality of contact grooves two 42 are formed on the side surface of the moving block two 4 away from the measuring rod 22, and the moving block two 4 is slidably installed with a contact block two 41 along the radial direction of the measuring rod 22 through the contact grooves two 42. A contact head 48 is fixed on the side surface of the contact block two 41 away from the measuring rod 22, and the contact head 48 can abut against the inner peripheral surface of the pipe fitting. Reset blocks 43 are fixed on both sides of the contact block two 41, reset grooves 44 are formed on the inner wall of the contact grooves two 42, and the reset blocks 43 are slidably matched with the moving block two 4 along the radial direction of the measuring rod 22 through the reset grooves 44. A reset spring 45 is fixed on the side surface of the reset block 43 close to the measuring rod 22, and one end of the reset spring 45 away from the reset block 43 is fixedly connected with the inner wall of the reset groove 44. An electromagnet 46 is fixed on the inner wall of the contact grooves two 42 close to the measuring rod 22, and the electromagnet 46 can repel the contact block two 41 after being powered on. A fixed contact piece two 47 is embedded and fixed on the inner wall of the reset groove 44, the reset block 43 can be in electrical contact with the fixed contact piece two 47, the fixed contact piece two 47 is electrically connected with the power supply, and the reset block 43 is electrically connected with the warning bell one 38.

[0033] When the pipe fitting does not move to the position of the contact block two 41, the electromagnet 46 is powered off, and the contact block two 41 fits with the electromagnet 46 under the elastic force of the reset spring 45. At this time, the reset block 43 is separated from the fixed contact piece two 47; when the pipe fitting moves to the position of the contact block two 41, the electromagnet 46 is powered on to work, the contact block two 41 moves towards the direction close to the pipe fitting under the repulsive force of the electromagnet 46, and the contact head 48 fits with the inner wall of the pipe fitting. When the wall thickness of the pipe fitting is greater than or equal to the standard size, the limiting block 34 remains in a separated state from the fixed contact piece two 47; when the wall thickness of the pipe fitting is less than the standard size, the limiting block 34 is in electrical contact with the fixed contact piece two 47, and the warning bell one 38 is powered on to work, thereby reminding the staff.

[0034] As Figure 3 、 Figure 5As shown, a horizontally arranged control rod 5 is fixed to the side of the rotating circular plate 13 close to the feeder 11. A plurality of control slots 51 are provided on the side of the control rod 5 close to the pipe. The control rod 5 is provided with a control block 58 that slides along its width direction through the control slots 51. The control block 58 corresponds one-to-one with the moving block 2 4. The control block 58 is located on the side of the corresponding moving block 2 4 away from the feeder 11. An inclined surface 1 52 is provided on the side of the control block 58 close to the pipe. The inclined surface 1 52 is located on the side of the control block 58 close to the feeder 11. A slider 53 is fixed to the side of the control block 58. A slide groove 54 is provided on the inner wall of the control slot 51. The slider 53 slides and cooperates with the control rod 5 along the width direction of the control rod 5 through the slide groove 54. A control spring 55 is fixed to the side of the slider 53 away from the pipe. The end of the control spring 55 away from the slider 53 is fixedly connected to the inner wall of the slide groove 54. A trigger piece 1 56 electrically connected to the electromagnet 46 is fixed to the side of the control block 58 away from the pipe. A trigger piece 2 57 for electrically contacting the trigger piece 1 56 is fixed to the inner wall of the control groove 51. The trigger piece 2 57 is electrically connected to the power supply.

[0035] When the pipe moves to the contact block 2 41 , the end of the pipe abuts against the control block 58 and pushes the control block 58 to move through the inclined surface 1 52 , so that the trigger piece 1 56 is in electrical contact with the trigger piece 2 57 , and the electromagnet 46 is energized to work, thereby facilitating the moving block 2 4 to detect the wall thickness of the pipe.

[0036] like Figure 2 、 Figure 3 As shown, a transfer table 6 is installed on the top surface of the detection table 1, and the transfer table 6 is located on one side of the feeder 11. A pushing component 7 for pushing the pipe fitting to move to the transfer table 6 is provided on the detection table 1, and a length detection component 9 for detecting the length of the pipe fitting is provided on the transfer table 6. The pushing component 7 includes a pushing cylinder 71 fixed on the fixed plate 12, and a pushing block 72 is fixed to the end of the piston rod of the pushing cylinder 71, and the pushing block 72 moves back and forth along the length direction of the measuring rod 22. An abutment groove 73 is provided on the side of the pushing block 72 close to the transfer table 6, and an abutment block 74 is installed on the pushing block 72 so as to slide along its own length direction through the abutment groove 73. The outer periphery of the measuring rod 22 is provided with a pushing circular tube 23, and the outer peripheral surface of the pushing circular tube 23 is in contact with the outer peripheral surface of the positioning circular rod 21. The outer circumference of the push tube 23 is provided with a clearance notch 24 for the passage of the control block 58. Two guide plates 25 are fixed to the outer circumference of the push tube 23, and the opposing inner sides of the two guide plates 25 are in contact with the side of the control rod 5. A brake plate 26 is fixed to the outer circumference of the push tube 23, and the abutment block 74 is capable of abutting the side of the brake plate 26 away from the transfer platform 6.

[0037] like Figure 2 、 Figure 6 、 Figure 7As shown in the figure, a sliding block 75 is fixed to the side surface of the abutting block 74, and a sliding groove 751 is formed in the inner wall of the abutting groove 73. The sliding block 75 is slidably engaged with the pushing block 72 along the length direction of the pushing block 72 through the sliding groove 751. A sliding spring 76 is fixed to the side surface of the sliding block 75 away from the transfer table 6, and one end of the sliding spring 76 away from the sliding block 75 is fixedly connected to the inner wall of the sliding groove 751. The length detection assembly 9 includes a warning bell II 91 fixed to the fixed plate 12. A connecting block I 92 electrically connected to the warning bell II 91 is fixed to the top surface of the transfer table 6. A detection block I 741 capable of making electrical contact with the connecting block I 92 is embedded and fixed on the side surface of the abutting block 74. The detection block I 741 is electrically connected to the power supply. A connecting block II 93 electrically connected to the warning bell II 91 is embedded and fixed on the inner wall of the sliding groove 751. The sliding block 75 can make electrical contact with the connecting block II 93, and the sliding block 75 is electrically connected to the power supply.

[0038] When the length of the pipe fitting is equal to the standard size, the abutting block 74 abuts against the pipe fitting and pushes the pipe fitting onto the transfer table 6. At this time, the sliding spring 76 is in its original state. When the pipe fitting moves to abut against the baffle 63, the detection block I 741 does not contact the connecting block I 92, and the sliding spring 76 deforms. The sliding spring 76 compresses a certain length, but the sliding block 75 does not contact the connecting block II 93. When the length of the pipe fitting is less than the standard size, when the pipe fitting moves to abut against the baffle 63, the detection block I 741 makes electrical contact with the connecting block I 92, and the warning bell II 91 gives an alarm. When the length of the pipe fitting is greater than the standard size, when the pipe fitting moves to abut against the baffle 63, the sliding spring 76 deforms greatly, the sliding spring 76 compresses a large length, the sliding block 75 makes electrical contact with the connecting block II 93, and the warning bell II 91 gives an alarm, thereby realizing the detection of the length of the pipe fitting.

[0039] As Figure 7 、 Figure 8 、 Figure 9 shown, the transfer table 6 includes a vertical plate 62 fixed to the top surface of the detection table 1 and a transfer plate 61 fixed to the top surface of the vertical plate 62. A baffle 63 for abutting against the pipe fitting is fixed to the top surface of the transfer plate 61. A blanking through groove 65 is formed in the top surface of the transfer plate 61. A placement box 64 for placing the pipe fitting is arranged below the transfer plate 61. Two connecting rods 66 are rotatably installed in the blanking through groove 65. An arc-shaped plate 67 is sleeved on the outer periphery of the connecting rod 66. The inner arc surface of the arc-shaped plate 67 can be attached to the outer peripheral surface of the pipe fitting. A torsion spring 68 is sleeved on the outer periphery of the connecting rod 66. One end of the torsion spring 68 is fixedly connected to the inner wall of the blanking through groove 65, and the other end of the torsion spring 68 is fixedly connected to the arc-shaped plate 67.

[0040] As Figure 7 、 Figure 8As shown in the figure, a separation component 8 for pushing two arc-shaped plates 67 to rotate away from each other is provided on the transfer table 6. Two connecting plates 81 are fixed to the top surface of the transfer plate 61, a support plate 82 is fixed to the top surface of the connecting plate 81, a downward pressing cylinder 83 is installed on the support plate 82, and a pressing plate 86 is fixed to the bottom end of the piston rod of the downward pressing cylinder 83. The separation component 8 includes a pulling rope 84 fixed to the bottom end of the arc-shaped plate 67. Rotating disks 85 are respectively installed on the side of the vertical plate 62 close to the arc-shaped plate 67 and the side of the connecting plate 81 close to the pressing plate 86. The pulling rope 84 successively bypasses the two rotating disks 85, and the other end of the pulling rope 84 is fixedly connected to the side of the pressing plate 86.

[0041] When the pipe fitting enters the arc-shaped plate 67 under the action of the pushing component 7, the pressing plate 86 moves downward under the action of the downward pressing cylinder 83, and at the same time drives the arc-shaped plate 67 to open through the pulling rope 84, so that the pipe fitting can enter the placing box 64 through the blanking through groove 65.

[0042] It should be noted that for this PP pipe fitting processing detection device, during use, the feeder 11 conveys the cut pipe fitting to the outer periphery of the measuring rod 22, and the first contact block 32 and the second contact block 41 detect the wall thickness of the pipe fitting. When the wall thickness of the pipe fitting does not meet the standard size, the first warning bell 38 emits an alarm; when the wall thickness of the pipe fitting meets the standard size, the driving motor 15 drives the rotating circular plate 13 to rotate, and the pipe fitting moves to a position close to the pushing block 72. The pushing cylinder 71 drives the pushing block 72 to move, and the abutting block 74 abuts against the braking plate 26 and drives the pushing circular tube 23 to move towards the direction close to the transfer table 6. When the length of the pipe fitting does not meet the standard size, the second warning bell 91 emits an alarm, the detection efficiency is relatively high, and the error is small; when the length of the pipe fitting meets the standard size, the downward pressing cylinder 83 drives the pressing plate 86 to move downward, the arc-shaped plate 67 opens, and the pipe fitting falls into the placing box 64.
