Description

Technical Field

[0001] The present application relates to the field of engine detection, and in particular to a nozzle detector and a detection method thereof. Background Art

[0002] When the engine piston is in working condition, the temperature of the piston head is very high. In order to ensure the working performance of the piston, the piston cooling nozzle needs to spray cooling oil to the piston with higher temperature. The cooling oil takes away the heat of the piston through heat exchange to cool the piston.

[0003] When cooling the piston, whether the spray direction of the piston cooling nozzle is correct directly affects the cooling effect of the piston, and thus affects the overall performance of the engine.

[0004] With respect to the above-mentioned related technologies, the inventors believe that after the piston cooling nozzle is prepared, the accuracy of the nozzle's landing point needs to be tested to ensure the quality of the nozzle leaving the factory. Summary of the invention

[0005] In order to achieve accurate detection of the nozzle landing point position, the present application provides a nozzle detector and a detection method thereof.

[0006] The present application provides a nozzle detector and a detection method thereof using the following technical solutions:

[0007] In a first aspect, the present application provides a nozzle detector, which adopts the following technical solution:

[0008] A nozzle tester comprises a support platform and a test platform, wherein the support platform is provided with a lifting assembly for controlling the test platform to move away from or close to the support platform, the test platform is provided with a mounting platform and a forward and backward moving assembly for controlling the forward and backward movement of the mounting platform, the test platform is provided with a mounting assembly for replacing the nozzle on the mounting platform, the support platform is connected with an oil pipe for supplying liquid to the nozzle, the support platform is provided with a receiving assembly for collecting the liquid output from the nozzle, the mounting platform is provided with a mounting groove for the nozzle to enter, the mounting platform is fixed with a driving member, and the output end of the driving member is used to fix the nozzle located in the mounting groove.

[0009] By adopting the above technical solution, the support platform can support each component, and the lifting component can suspend the detection platform above the support platform, creating a height difference between the support platform and the detection platform. After the nozzle on the support platform is connected to the through oil pipe, the nozzle head of the nozzle discharges liquid and then sprays it onto the receiving component on the detection platform. The lifting component can adjust the height difference between the detection platform and the support platform, so as to enable the nozzle on the installation platform to detect different height positions of the landing point. The lifting component can also control the movement of the detection platform away from or close to the support platform, thereby simulating the situation when the nozzle is working. The installation groove in the installation platform can achieve the preliminary limit of the nozzle. The driving component can, on the one hand, fix the nozzle and, on the other hand, block the upper opening of the nozzle ring part. The through oil pipe enters the nozzle from the bottom of the installation groove, and then the nozzle starts to discharge liquid, and then the accuracy of the landing point position is detected. The front and rear moving component can determine the relative position of the installation platform, so that the nozzle can also be installed in the accurate position, which can reduce the detection error. The receiving component can collect the liquid sprayed by the nozzle, and can obtain the liquid discharge amount of the nozzle head at the landing point position. By comparing this liquid discharge amount with the total liquid discharge amount of the nozzle head, the accuracy of the nozzle landing point position can be detected; the installation component can replace the detected nozzle and the undetected nozzle, thereby realizing automatic loading and unloading and improving the working efficiency of the equipment.

[0010] Optionally, a convex ring is provided in the installation groove, and a push ring is slidably arranged in the axial direction of the convex ring. The push ring is connected to the bottom wall of the installation groove by an installation spring for pushing the nozzle to expose out of the installation groove, and the installation groove is communicated with the through oil pipe.

[0011] By adopting the above technical solution, the push ring is used to support the nozzle. When the detection is completed, the installation spring can be used to make the push ring push the nozzle, so that the ring part of the nozzle is exposed out of the installation groove. The bottom of the ring part of the nozzle is located at the rounded corner, which is convenient for pushing the nozzle to make the nozzle come out of the installation groove. When detecting the nozzle, the top of the convex ring abuts against the bottom of the nozzle, which can reduce the inflow of liquid from between the convex ring and the nozzle to the position of the installation spring, reducing the influence of the liquid on the installation spring.

[0012] Optionally, the lifting assembly includes a lifting screw and a lifting motor. The lifting motor is fixed to the support table, and the output end of the lifting motor is fixedly connected to the lifting screw. The lifting screw is threadedly connected to the inspection table. The support table is provided with a left-right moving assembly. The front-back moving assembly includes a front-back moving screw, a front-back moving motor, and a front-back moving platform. The front-back moving motor is fixed to the inspection table, and the output end of the front-back moving motor is fixedly connected to the front-back moving screw. The front-back moving screw is threadedly connected to the front-back moving platform. The left-right moving assembly is mounted on the front-back moving platform. The left-right moving assembly includes a left-right moving screw and a left-right moving motor. The output end of the left-right moving motor is connected to the left-right moving screw. The left-right moving screw is threadedly connected to the mounting table.

[0013] By adopting the above technical solution, the lifting motor can drive the lifting screw to rotate. The screw drive method can improve the transmission stability and can be adjusted precisely, enabling accurate control of the vertical movement distance of the inspection table relative to the support table. The front-back moving assembly is located on the inspection table. When the inspection table moves under the action of the lifting screw, the front-back moving platform can remain stationary relative to the inspection table. The front-back moving motor can drive the front-back moving screw to rotate. Since the front-back moving screw is also threadedly connected to the front-back moving platform, when the front-back moving screw rotates, the front-back moving platform can be pressed to prevent rotation because there is a mounting table on the front-back moving platform, so that the front-back moving screw can drive the front-back moving platform to move forward and backward, and thus the mounting table located on the front-back moving platform can move forward and backward. The left-right moving assembly is located on the front-back moving platform. The left-right moving motor can drive the left-right moving screw to rotate. Since the left-right moving screw is threadedly connected to the mounting table, similarly, when the left-right moving screw rotates, the mounting table can move left and right. When the mounting table moves forward and backward, it can be linked with the mounting assembly. On the one hand, it can unload the inspected nozzles, and on the other hand, it can install new nozzles into the installation slot, realizing the replacement of nozzles through forward and backward movement, shortening the nozzle replacement time, and ultimately improving the detection work efficiency of the equipment.

[0014] Optionally, the mounting table is provided with a discharging assembly. The mounting assembly includes a feeding box, a discharging guide plate, and a discharging block. The feeding box has a stacking port and a blanking port. A baffle is slidably connected to the blanking port. The feeding box is fixedly arranged on the inspection table. The mounting table is provided with a pushing block that can push the baffle. A pushing spring is arranged between the pushing block and the mounting table. The nozzle in the blanking port can enter the installation slot. The discharging block is used to drive the discharging assembly so that the output end of the discharging assembly pushes the nozzle located in the installation slot into the discharging guide plate.

[0015] By adopting the above technical solution, the unloading component can replace the detected nozzle from the installation groove and enter the discharge guiding plate. The unloading block is used to trigger the unloading component to start working. The stacking port allows the staff to put the undetected nozzle into the feeding box. During the process of the installation table moving towards the feeding box, the detected nozzle can be unloaded first by using the unloading block and the unloading component. As the installation table continues to move, the pushing block can push the baffle plate to open the blanking port. At this time, the installation groove is located below the blanking port, and the undetected nozzle will come out from the blanking port and enter the installation groove. The nozzle tip abuts against the side of the baffle plate. Only when the baffle plate is fully opened will the nozzle completely come out from the blanking port, so as to realize the discharging of the detected nozzle first and then the installation of the new nozzle. The pushing block is used to push the baffle plate to move, and the pushing spring can achieve the buffering of the pushing block. When the baffle plate is fully opened, the pushing spring will be stressed to keep the pushing block in a tightened state, and at the same time, it can prevent the baffle plate from directly transmitting the force to the installation table, ultimately reducing the large internal stress borne by the feeding box and the installation table, and having a buffering effect.

[0016] Optionally, the unloading component includes a transmission block, a sealing block and a pushing block. A sealing cavity and a pushing cavity are formed inside the installation table. The transmission block can push the sealing block to slide in the sealing cavity. A sealing spring for resetting the sealing block is arranged in the sealing cavity. The pushing block can slide in the pushing cavity and can push the nozzle after extending out of the pushing cavity.

[0017] By adopting the above technical solution, the gas in the sealing cavity is in a sealed state, and its initial air pressure is at normal pressure, equal to the external air pressure. The transmission block can push the sealing block to compress the air in the sealing cavity. When the air pressure in the sealing cavity increases, since the air pressure in the sealing cavity is greater than the normal external air pressure, the air pressure in the sealing cavity will push the pushing block in the pushing cavity, so that one end of the pushing block comes out of the pushing cavity. The protruding end of the pushing block can push the nozzle tip. The chamfer at the opening of the installation groove can facilitate the pushing of the whole nozzle for discharging. Finally, the unloading of the nozzle is realized. The sealing spring can reset the sealing block. During the reset process, the space in the sealing cavity changes from small to large. Thus, the air pressure in the sealing cavity changes from greater than normal pressure to less than normal pressure. When the sealing cavity is less than normal pressure, the negative pressure in the sealing cavity can suck the pushing block into the pushing cavity. The pushing block located in the pushing cavity can avoid interfering with the newly installed nozzle, thereby realizing the fixation of the nozzle by the driving part.

[0018] Optionally, a transmission cavity is formed in the mounting table. The bottom of the transmission cavity communicates with the outside. The transmission block can slide in the transmission cavity. The transmission block has an abutting surface and a clamping groove. A groove is formed in the discharging block. An abutting block that can slide in the groove and an abutting spring for resetting the abutting block are arranged in the groove. The abutting block can abut against the abutting surface, and the abutting block is adapted to the clamping groove.

[0019] By adopting the above technical solution, the transmission cavity can realize the movement of the transmission block. When the abutting block abuts against the abutting surface, on the one hand, it can push the transmission block into the transmission cavity. On the other hand, since the bottom of the transmission cavity communicates with the outside, when the mounting table continues to move towards the feeding box, the abutting block will not interfere with the installation. When the transmission block enters the interior of the transmission cavity and reaches the bottom, since the mounting table will continue to move, at this time, the transmission block will instead push the abutting block into the groove. Then, when the mounting table continues to move and the abutting block is located above the clamping groove, the abutting block will enter the clamping groove under the action of the abutting spring; at this time, after the nozzle in the feeding box enters the installation groove, the mounting table starts to reset, and the abutting block abuts against the clamping groove, causing the transmission block to also enter the reset state; when the transmission block reaches the initial position, the side wall of the clamping groove will push the abutting block into the clamping groove, causing the installation block to continue to reset, and finally making the nozzle reach the corresponding position, and then detecting the nozzle.

[0020] Optionally, a storage cavity adapted to the nozzle is formed inside the feeding box. The storage cavity communicates with the stacking port and the blanking port respectively. A linkage groove is formed in the side wall of the storage cavity. A anti-falling plate is arranged in the linkage groove. The anti-falling plate can rotate relative to the linkage groove. One end of the anti-falling plate can enter the storage cavity to abut against the nozzle, and the other end of the anti-falling plate is connected with an elastic cord. The elastic cord is fixedly connected to the baffle.

[0021] By adopting the above technical solution, the storage cavity is used to store the nozzles. Since the storage cavity is adapted to the nozzles, it can play a role in limiting and arranging the nozzles. During the opening process of the baffle, the elastic cord will pull the anti-falling plate, so that one end of the anti-falling plate enters the interior of the storage cavity and abuts against the remaining nozzles, allowing only one nozzle to come out from the blanking port. Thus, it can be avoided that when the blanking port is opened, multiple nozzles all come out from the blanking port. The abutting block can push the baffle, and the abutting spring can buffer the abutting block when it receives a large reaction force, reducing the damage to the feeding box. When the elastic cord is pulled, it indicates that the baffle is in the open state, allowing the anti-falling plate to rotate. When the mounting table is reset, the elastic cord can pull the baffle to close the blanking port, realizing the blanking cycle.

[0022] Optionally, the receiving component includes a receiving column, a splash guard, a cover, and a receiving cylinder. The receiving column is provided with a receiving hole, and the receiving cylinder is used to drive the cover to block the receiving hole. The receiving column is located inside the splash guard. The support platform is provided with a receiving box and a circulation box. The receiving box is communicated with the receiving column, the circulation box is communicated with the surface of the support platform located inside the splash guard, a circulation pipeline is connected between the receiving box and the circulation box, and the circulation box is connected with the oil supply pipe.

[0023] By adopting the above technical solution, the receiving column is used to receive the liquid sprayed by the nozzle, the receiving box is used to collect the liquid sprayed by the receiving column, the splash guard can prevent the liquid that fails to be collected by the receiving column from splashing, and the liquid is collected by the circulation box. When the detection of the nozzle is completed, the receiving cylinder can push the cover to cover the end of the receiving column to prevent excess liquid from entering the receiving box. By calculating the liquid in the receiving box, the accuracy of the nozzle shooting can be obtained. After the detection is completed, the circulation pipeline can input the water in the receiving box into the circulation box to realize the recycling of the liquid.

[0024] Optionally, the support platform is provided with a collection box, the collection box is communicated with the surface of the support platform located outside the splash guard, and a filter pipeline is connected between the collection box and the circulation box.

[0025] By adopting the above technical solution, the collection box can collect the liquid on the surface of the support platform, and the filter pipeline is used to transport the liquid to the circulation box for secondary utilization.

[0026] In a second aspect, the present application provides a detection method, adopting the following technical solution:

[0027] S1: Install the nozzle to be detected on the installation platform, and then the driving member fixes the nozzle.

[0028] S2: Determine the relative position of the installation platform through the left-right moving component and the front-back moving component.

[0029] S3: The oil supply pipe injects liquid into the nozzle through the installation groove, so that the nozzle starts to spray liquid, and the liquid is sprayed into the receiving column at a stable pressure and stable water volume and enters the receiving box.

[0030] S4: The lifting component drives the detection platform to move up and down, and the nozzle continues to work, thereby simulating the state of the nozzle spraying into the receiving column during operation.

[0031] S5: Obtain the water volume of the cooling water in the receiving box, and compare the water volume of the cooling water in the receiving box with the water volume of the cooling water sprayed by the nozzle, so as to obtain the accuracy of the nozzle spraying.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The lifting component can continuously change the height difference between the support table and the detection table to simulate the working condition of the nozzle. The receiving component can collect the liquid ejected by the nozzle, and can obtain the liquid discharge amount at the landing position of the nozzle head. By comparing this liquid discharge amount with the total liquid discharge amount of the nozzle head, the accuracy of the nozzle landing position can be detected.

[0034] 2. When the installation table moves back and forth, it can be linked with the installation component. On the one hand, it can unload the detected nozzles, and on the other hand, it can install new nozzles into the installation slots. By moving back and forth, the replacement of the nozzles is realized, the nozzle replacement time is shortened, and finally the detection work efficiency of the equipment is improved.

[0043] The following is a further detailed description of this application in conjunction with the attached Figure 2-7 figures.

[0044] An embodiment of this application discloses a nozzle detector and its detection method.

[0045] Referring to Figure 2 , a nozzle detector includes a support table 1. The bottom of the support table 1 has an accommodating groove 13. A receiving assembly 7 is arranged in the accommodating cavity. The input end of the receiving assembly 7 is connected to the upper surface of the support table 1. A lifting assembly 3 is arranged on the upper surface of the support table 1. The lifting assembly 3 includes a lifting screw 31, a lifting motor 32 and a lifting guide rail 33. The lifting guide rail 33 is vertically and fixedly arranged on the support table 1. The lifting guide rail 33 is slidably connected with a detection table 11. The lifting screw 31 is threadedly connected with the detection table 11. The output shaft of the lifting motor 32 is fixedly connected to the lifting screw 31. When the lifting motor 32 rotates, the lifting screw 31 can be rotated. Under the guidance of the lifting guide rail 33, the lifting of the detection table 11 can be realized. In this embodiment, when the detection table 11 moves towards the support table 1, it is a descent, and when it moves away from the support table 1, it is an ascent.

[0046] A front-back moving assembly 5 is provided on the detection table 11. The front-back moving assembly 5 includes a front-back moving screw 51, a front-back moving motor 52, a front-back moving platform 53, and a front-back moving guide rail 54. The front-back moving motor 52 is fixed on the upper surface of the detection table 11. The output shaft of the front-back moving motor 52 is fixedly connected to the front-back moving screw 51. The length direction of the axis of the front-back moving screw 51 is the front-back direction. The front-back moving guide rail 54 is fixedly arranged on the detection table 11 and its arranged length direction is the same as the axis direction of the front-back moving screw 51. The front-back moving platform 53 is slidably connected to the front-back moving guide rail 54. The front-back moving screw 51 is threadedly connected to the front-back moving platform 53. When the front-back moving motor 52 drives the front-back moving screw 51 to rotate, the front-back moving screw 51 can make the front-back moving platform 53 move forward and backward along the length direction of the front-back moving guide rail. An installation assembly 6 is provided on the detection table 11. The movement of the front-back moving platform 53 in the direction close to the installation assembly 6 is forward movement, and the movement away from the installation assembly 6 is backward movement.

[0047] A left-right moving assembly 4 is provided on the front-back moving platform 53. The left-right moving assembly 4 includes a left-right moving screw 41, a left-right moving motor 42, a left-right moving guide rail 44, and an installation table 2 slidable along the left-right moving guide rail 44. The left-right moving motor 42 is fixed on the front-back moving platform 53. The output shaft of the left-right moving motor 42 is fixedly connected to the left-right moving screw 41. The axis of the left-right moving screw 41 and the axis of the front-back moving screw 51 are perpendicular to each other when projected onto the upper surface of the detection table 11. The left-right moving guide rail 44 is fixed on the front-back moving platform 53. The installation table 2 is slidably arranged on the left-right moving guide rail 44. The left-right moving screw 41 is threadedly connected to the installation table 2. When the left-right moving motor 42 drives the left-right moving screw 41 to rotate, the left-right moving screw 41 can be rotated, and the rotation of the left-right moving screw 41 can drive the installation table 2 to move along the length direction of the left-right moving guide rail 44. In this embodiment, the side of the installation table 2 facing the left-right moving motor 42 is the right side, and the side away from the left-right moving motor 42 is the left side.

[0048] Refer to Figure 3 and Figure 4 The installation assembly 6 is used to replace the nozzle 12 onto the installation table 2. A controller is provided on the detection table 11, which can control the left-right moving assembly 4 and the front-back moving assembly 5 to align the nozzle of the nozzle 12 on the installation table 2 with the input end of the receiving assembly 7. This controller is a prior art, so it will not be elaborated here.

[0049] The mounting table 2 is provided with a mounting groove 21 for mounting the nozzle 12. One side of the mounting table 2 is connected with an oil supply pipe 22. One end of the oil supply pipe 22 communicates with the mounting groove 21, and the other end of the oil supply pipe 22 communicates with the output end of the receiving component 7. The mounting table 2 is fixed with a driving member 23, which is an electric push rod. The output end of the electric push rod can abut against the nozzle 12 located in the mounting groove 21 to fix the nozzle 12. There is a convex ring 211 in the mounting groove 21. The cross section of the convex ring 211 is L-shaped. A push ring 212 is slidably arranged along the axial direction of the convex ring 211. The bottom of the push ring 212 abuts against the top of the convex ring 211. The nozzle 12 in the mounting groove 21 is supported by the convex ring 211. An installation spring 213 is arranged at the horizontal position of the push ring 212 and the convex ring 211. When the electric push rod fixes the nozzle 12, the bottom of the push ring 212 abuts against the convex ring 211, and the installation spring 213 is in a state of storing energy. When the output end of the electric push rod releases the fixation of the nozzle 12, the installation spring 213 can push the push ring 212 to expose the nozzle 12 from the mounting groove 21. The mounting table 2 is also provided with a discharging component 8 for discharging the nozzle 12 exposed from the mounting groove 21. In this embodiment, the opening of the mounting groove 21 has a chamfer, which can facilitate the discharging component 8 to discharge the detected nozzle 12.

[0050] Referring to Figure 5 and Figure 6 Figure, the interior of the mounting table 2 is provided with a sealing cavity 81, a pushing cavity 82 and a transmission cavity 83. The transmission cavity 83 communicates with the sealing cavity 81, and the sealing cavity 81 communicates with the pushing cavity 82. The discharging component 8 includes a transmission block 84, a sealing block 811 and a pushing block 821. The transmission block 84 can slide in the transmission cavity 83, and the sealing block 811 is located in the sealing cavity 81. When the sealing block 811 is in the initial state, a part of the sealing block 811 is located in the transmission block 84. At this time, the sealing cavity 81 is in an atmospheric pressure state. A sealing strip is arranged between the sealing block 811 and the sealing cavity 81 to realize the sealing of the gas in the sealing cavity 81. A sealing spring 812 is arranged in the sealing cavity 81. The two ends of the sealing spring 812 are fixedly connected to the sealing block 811 and the side wall of the sealing cavity 81. When the sealing block 811 is in the initial state, the sealing spring 812 is not in a state of storing energy. After the sealing spring 812 stores energy, it can force the sealing block 811 to move away from the direction where the sealing cavity 81 communicates with the pushing cavity 82. The pushing block 821 is located in the pushing cavity 82. The pushing block 821 can slide in the pushing cavity 82 and one end of the pushing block 821 can come out of the pushing cavity 82. When the nozzle 12 is exposed from the mounting groove 21, the pushing block 821 coming out of the pushing cavity 82 can push the nozzle 12 to drop the material.

[0051] The bottom of the transmission cavity 83 is communicated with the outside. The transmission block 84 is L-shaped and can slide in the transmission cavity 83 without falling out of the transmission cavity 83. When the transmission block 84 slides into the transmission cavity 83, it can push the sealing block 811, causing the sealing block 811 to enter the piston state from the initial state. After being squeezed, the seal will generate pressure, making the air pressure in the sealing cavity 81 greater than the outside air pressure. When the air pressure in the sealing cavity 81 is greater than a certain level, it can push the pushing block 821 located in the pushing cavity 82, enabling the pushing block 821 to push the nozzle 12 for discharging materials. When the transmission block 84 comes out of the transmission cavity 83, the sealing cavity 81 moves towards the transmission cavity 83 under the thrust of the sealing spring 812. The space of the sealing cavity 81 becomes larger. At this time, the gas pressure in the sealing cavity 81 changes from being greater than the outside air pressure to being less than the outside air pressure, thereby sucking the pushing block 821 leaking outside the pushing cavity 82 into the pushing cavity 82.

[0052] Refer to Figure 3 and 7 , the installation component 6 includes a feeding box 61, a discharging guide plate 62 and a discharging block 63. The discharging block 63 is used to drive the transmission rod to move in the transmission cavity 83. The discharging nozzle 12 will fall into the discharging guide plate 62. The feeding box 61 can output new nozzles 12 to be detected, and the undetected nozzles 12 will enter the installation groove 21.

[0053] The discharging block 63 is fixed to the detector, and a groove 631 is provided on the upper surface of the discharging block 63. An abutting block 632 is arranged in the groove 631 and can slide in the groove 631. Abutting spring 633 is also arranged in the groove 631. The two ends of the abutting spring 633 are respectively fixedly connected to the lower surface of the abutting block 632 and the bottom of the groove 631. The abutting spring 633 can make the discharging block 63 protrude from the groove 631. The transmission block 84 has an abutting surface 841 and a clamping groove 842. When the front and rear moving motor 52 drives the mounting table 2 to move forward, the abutting block 632 will abut against the abutting surface 841 of the transmission block 84. At this time, the abutting block 632 will push the transmission block 84 into the transmission groove, and then make the pushing block 821 come out of the pushing cavity 82 to push the nozzle 12, causing the nozzle 12 to fall into the discharging guide plate 62. The discharging guide plate 62 is inclined, and the nozzle 12 falling into the discharging guide plate 62 will slide to the lowest position to reduce the accumulation of the nozzles 12. When the transmission block 84 completely enters the transmission cavity 83, the transmission block 84 will instead push the abutting block 632, causing the abutting block 632 to enter the groove 631. At this time, the mounting table 2 continues to move forward. When the clamping groove 842 of the transmission block 84 is directly above the abutting block 632, the abutting block 632 enters the clamping groove 842 under the action of the abutting spring 633.

[0054] While the abutting block 632 enters the clamping groove 842, the nozzle 12 in the feeding box 61 will enter the mounting groove 21. Then, the mounting table 2 moves backward. The abutting block 632 in the clamping groove 842 will pull the transmission block 84 out of the transmission cavity 83. When the transmission block 84 moves to the outermost part of the transmission cavity 83, at this time, the side wall of the clamping groove 842 will push the abutting block 632 into the groove 631, and then the mounting table 2 continues to move backward. Then, the driving member 23 will press the nozzle 12 located in the mounting groove 21, and under the action of the left-right moving assembly 4 and the front-back moving assembly 5, the nozzle of the nozzle 12 will be aligned with the input end of the receiving assembly 7.

[0055] The feeding box 61 is fixed to the inspection table 11. A storage cavity 614 for placing the nozzles 12 that have not been inspected is provided inside the feeding cavity. The storage cavity 614 is adapted to the nozzle 12 to realize the neat stacking of the nozzles 12. The upper part of the feeding box 61 has a stacking port 611 through which the uninspected nozzles 12 can be placed in the storage cavity 614. The lower part of the feeding box 61 has a blanking port 612. A baffle 613 is slidably connected to the blanking port 612. When the baffle 613 is closed, it can prevent the nozzles 12 in the storage cavity 614 from coming out through the blanking port 612. When the abutting block 632 enters the clamping groove 842, the mounting groove 21 is exactly located below the blanking port 612. At this time, the baffle 613 is in an open state, and the nozzles 12 in the storage cavity 614 will come out from the blanking port 612 and enter the mounting groove 21.

[0056] A linkage groove 615 is provided on the side wall of the storage cavity 614. On the one hand, it is communicated with the dust removal cavity, and on the other hand, it is also communicated with the outside. A falling prevention plate 616 is rotatably provided on the side wall of the dust removal cavity. A torsion spring is installed at the rotation point of the falling prevention plate 616. The torsion spring can make one end of the falling prevention plate 616 enter the dust removal cavity without being pulled by an external force, and can abut against the nozzle of the nozzle 12, so that when the baffle 613 is opened, only one nozzle 12 enters the mounting groove 21. One end of the falling prevention plate 616 away from the dust removal cavity is fixedly connected with an elastic rope 617, and the other end of the elastic rope 617 is connected to one end of the baffle 613. The elastic rope 617 can make the falling prevention plate 616 and the baffle 613 generate linkage.

[0057] The mounting table 2 is provided with a pushing block 24 that can push the baffle 613, and a pushing spring 25 for buffering the pushing block 24 is arranged between the pushing block 24 and the mounting table 2; when the mounting table 2 moves forward, after the pushing block 24 abuts against the baffle 613, the baffle 613 will be pushed; during the opening process of the baffle 613, on the one hand, the elastic cord 617 is stretched and will pull the anti-falling plate 616 to rotate, and the anti-falling plate 616 can block the second nozzle 12 in the material dropping port 612, on the other hand, the pushing block 821 will discharge the nozzle 12 on the mounting groove 21; after the discharging is completed, the baffle 613 is in a fully open state, and the first nozzle 12 not blocked by the anti-falling plate 616 will fall into the mounting groove 21. Then the mounting table 2 moves backward, and the baffle 613 enters the closed state under the pulling force of the elastic cord 617, realizing the replacement of the nozzle 12.

[0058] Referring to Figure 3 , the receiving assembly 7 includes a receiving box 75, a circulating box 76 and a collection bucket. The input end of the receiving box 75 is communicated with the upper surface of the support table 1, and a receiving column 71 is arranged at the communicating place. The receiving column 71 is provided with a receiving hole 711, and the liquid sprayed out by the nozzle 12 enters the receiving box 75 through the receiving hole 711. The receiving box 75 is provided with a gravity detector that can detect the gravity of the liquid in the receiving box 75. The gravity detector in this embodiment is a weighing scale, and this gravity detector is a prior art and is not shown in the figure. A splash guard 72 is arranged at the receiving column 71 on the support table 1. The splash guard 72 is in a cylindrical shape, and the bottom is fixed to the upper surface of the support table 1. A receiving cylinder 74 is arranged on the support table 1. The output end of the receiving cylinder 74 passes through the splash guard 72, and a cover 73 is arranged at the end of the output end. When the detection of one of the nozzles 12 is completed, the receiving cylinder 74 is driven to make the cover 73 block the receiving hole 711 of the receiving column 71.

[0059] The receiving box 75, the circulating box 76 and the collection bucket are all located in the accommodation groove 13 at the bottom of the support table 1. A circulating pipeline 77 is connected between the circulating box 76 and the receiving cavity. After the gravity of the liquid in the receiving box 75 is detected, it can enter the circulating box 76 through the circulating pipeline 77. The output end of the circulating box 76 is connected to the oil supply pipe 22, so that the liquid in the circulating box 76 can be used continuously. The collection bucket is communicated with the upper surface of the support table 1. When the nozzle 12 is detected and the liquid splashes out from the splash guard 72, the collection bucket can collect the liquid splashed on the support table 1. The collection bucket is connected to the circulating box 76 through a filtering pipeline 79, and the filtered liquid can be input into the circulating box 76 for continuous circulation use.

[0060] A detection method for the above nozzle 12 detector:

[0061] S1: Install the nozzle 12 to be detected on the mounting table 2, and then the driving member 23 fixes the nozzle 12.

[0062] S2: Determine the relative position of the mounting table 2 by moving the component 4 left and right and the component 5 forward and backward, so that the nozzle of the nozzle 12 can be aligned with the receiving hole 711.

[0063] S3: The oil pipe 22 injects the liquid into the nozzle 12 through the mounting groove 21, so that the nozzle 12 starts to spray the liquid, and sprays the liquid into the receiving hole 711 with a stable pressure and a stable water volume, and then enters the receiving tank 75.

[0064] S4: The lifting component 3 drives the inspection table 11 to move up and down, so that the height difference between the nozzle 12 and the receiving hole 711 changes continuously, thereby simulating the state of the nozzle 12 during operation.

[0065] S5: After the detection is completed, the weight detector can detect the total weight of the receiving tank 75, so as to obtain the water volume of the cooling water in the receiving tank 75. Comparing the water volume of the cooling water in the receiving tank 75 with the water volume of the cooling water sprayed by the nozzle 12, the accuracy of the nozzle 12 spraying into the receiving hole 711 can be obtained. For example, if the total spraying volume of the nozzle 12 is 500 grams or milliliters, and the water volume received by the receiving tank 75 is 400 grams or milliliters, the accuracy is 90%, and it can be considered that the accuracy is high. When the accuracy is lower than a certain value, such as lower than 80%, the accuracy is considered low.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
