[0056] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0057] In the present invention, unless otherwise stated, the directional terms such as "upper, lower, inner, outer" included in the terms only represent the directions of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation of the terms.

[0058] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides an automatic detection device for the water seal jump of a water pump. The automatic detection device for the water seal jump of the water pump includes a machine body 1 and a water pump support mechanism 7 provided on the upper surface of the machine body 1 for supporting and limiting the bottom of the water pump body 6. Above the water pump support mechanism 7, a limit test mechanism 3 capable of driving the top rotating shaft 16 of the water pump body 6 to rotate is provided in a liftable manner. A displacement sensor 8 is also provided on the machine body 1. The detection head of the displacement sensor 8 vertically passes through the water pump support mechanism 7 and contacts the preset reference surface at the bottom of the water pump body 6 to detect the height of the reference surface in the initial state of the water pump body 6 and the jump value of the detection head of the displacement sensor 8 around the reference surface in the detection state; wherein,

[0059] The limit test mechanism 3 includes an equipment box 301, an assembly plate 312 horizontally provided at the bottom of the equipment box, and a limit plate 305 parallelly provided directly below the assembly plate 312 through a plurality of vertically arranged elastic connectors. A positioning hole 313 through which a part of the top rotating shaft 16 of the water pump body 6 can pass is provided at the center of the limit plate 305. A claw cylinder 309 for fixing the top rotating shaft 16 of the water pump body 6 and coaxially arranged with it is provided on the lower surface of the assembly plate 312 and in the central axis direction of the positioning hole 313. A driving motor 306 for driving the claw cylinder 309 to rotate about its central axis is provided in the equipment box 301.

[0060] In the above solution, when the automatic detection device is in use, the water pump body 6 to be detected is placed on the water pump support mechanism 7, which supports and limits it from the bottom, and ensures that the rotating shaft 16 on the water pump body 6 is in a vertical state. Then, the limit test mechanism 3 is driven to descend so that the limit plate 305 limits the water pump body 6 from the top, and cooperates with the water pump support mechanism 7 to stably limit and support its body. Then, the clamping cylinder 309 is used to clamp and fix the top of the rotating shaft 16 on the water pump body 6, and a rotation test is carried out under the driving action of the driving motor 306. The displacement sensor 8 at the bottom of the water pump body 6 can respectively detect the height of the water pump body 6 in the initial state and the jump value of the detection head of the displacement sensor 8 around the reference plane in the detection state to obtain the detection value. According to the detection value, the quality and quality of the water pump body 6 can be judged, and it can be sorted. The device of the present application can ensure the stability of the water pump body 6 during the rotation test of its rotating shaft, and cooperate with the displacement sensor 8 to ensure the accuracy of the water seal jump detection of the water pump body 6.

[0061] As Figure 9 and Figure 10 shown, in a preferred embodiment of the present invention, the water pump support mechanism 7 includes a workbench 702 arranged at intervals through a support rod and horizontally assembled on the upper surface of the machine body 1. A quick-change base 701 is detachably arranged on the workbench 702, and several limit support columns 703 vertically arranged on the upper surface of the quick-change base 701 and adapted to the bottom structure of the water pump body 6. A support central shaft 704 is vertically and rotatably arranged at the center of the quick-change base 701. The bottom of the rotating shaft 16 on the water pump body 6 rotatably extends into the support central shaft 704, and the detection head of the displacement sensor 8 also extends into the support central shaft 704 and contacts the preset reference plane at the bottom of the water pump body 6.

[0062] As Figure 3 and Figure 5 shown, a code scanning gun 5 for obtaining the two-dimensional code information on the water pump body 6 is also vertically arranged on the upper surface of the machine body 1 and on one side of the water pump support mechanism 7.

[0063] In the above solution, the code scanning gun 5 is used to scan the two-dimensional code of the water pump body 6 to be detected to obtain and record the serial number information of the water pump body 6, so as to understand the information of the water pump body to be detected, bind its information with its detection data, so as to facilitate the subsequent retrieval and understanding of the water seal jump detection data of the water pump body, and facilitate the management, viewing and traceability of the detected data.

[0064] As Figure 3 , Figure 5 and Figure 10As shown, a misplaced proximity switch is provided on the upper surface of the workbench 702, and an anti-misplacement photoelectric switch 4 is provided on the upper surface of the machine body 1 and on one side of the workbench 702, and the anti-misplacement photoelectric switch 4 emits a detection light beam towards the top rotating shaft 16 of the water pump body 6.

[0065] In the above solution, the quick-change base 701 will be replaced to install water pump bodies to be detected with different specifications and types. To ensure the replacement effect and detection accuracy, generally there are three types of quick-change bases 701, which can be adapted to at least three types of water pump bodies for detection. Moreover, sometimes the two-dimensional code is also misprinted. If it is wrong, it will cause the limit testing mechanism to collide with the equipment, easily causing damage to the equipment of this application and significant losses. And the above structure provides multiple anti-misplacement measures to ensure the accurate acquisition of the water pump body information;

[0066] Among them, the detection light beam emitted by the anti-misplacement photoelectric switch 4 can detect the assembly height of the water pump body, so as to obtain the corresponding type of quick-change base 701 and the water pump body information. At this time, the data for automatically driving the limit testing mechanism 3 to descend is also adapted to it to ensure the detection accuracy and prevent collision accidents;

[0067] And the misplaced proximity switch is adapted to the detection groove on the quick-change base 701. The detection groove of one type of quick-change base 701 is solid and can block the misplaced proximity switch, while the detection groove of another type of quick-change base 701 is through and cannot block the misplaced proximity switch. According to these two situations, the types of the two quick-change bases 701 can be distinguished to identify different types of water pump bodies assembled on the two quick-change bases 701 for detection.

[0068] The above two types of anti-misplacement switches can detect at least three types of quick-change bases 701 and water pump bodies to ensure the acquisition of the water pump body information, so as to further prevent the limit testing mechanism 3 from colliding with the water pump body and ensure the detection accuracy.

[0069] As Figure 4 and Figure 6 shown, in a preferred embodiment of the present invention, the limit testing mechanism 3 is assembled on the upper surface of the machine body 1 in a liftable manner through a driving mechanism; among them,

[0070] The driving mechanism includes: a support column 12, a stepping motor 9, and a driving lead screw 10; the support column 12 is vertically assembled on the upper surface of the machine body 1, and a strip-shaped groove is formed by partial inward depression on one side of the support column 12 opposite to the limit testing mechanism 3. The two ends of the driving lead screw 10 are respectively and vertically and rotatably arranged in the strip-shaped groove through fitting blocks. The stepping motor 9 is arranged on the top of the support column 12, and the output shaft of the stepping motor 9 is coaxially connected to the top end of the driving lead screw 10 through a coupling. A lifting seat 11 is arranged on the driving lead screw 10 in a threaded manner. An ascending and descending groove parallel to the driving lead screw 10 is also arranged on the support column 12. A part of the lifting seat 11 extends out from the ascending and descending groove and is assembled with the limit testing mechanism 3.

[0071] In the above solution, in the above solution, the driving mechanism of the present application is a driving mechanism of a motor cooperating with a lead screw, which can further improve the stability after the limit testing mechanism 3 limits and fixes the water pump body, and the smoothness during the lifting and lowering process of the driving structure driving the limit testing mechanism 3 is also better. In this way, the process of the limit testing mechanism 3 acting on the water pump body until it is pressed is also smoother and slower, which can protect and stably limit the water pump body 6; among them,

[0072] The driving working principle of the driving mechanism is: the stepping motor drives the driving lead screw 10 to rotate. Under the combined action of the threaded structure and the ascending and descending groove, the lifting seat 11 can be lifted and lowered along the length direction of the driving lead screw 10, thereby driving the limit testing mechanism 3 to lift and lower.

[0073] In a preferred embodiment of the present invention, a slide rail 14 is arranged on one side of the support column 12 facing the limit testing mechanism 3 along the vertical direction. The side surface of the limit testing mechanism 3 is slidably assembled on the slide rail 14 through a slider 15.

[0074] In the above solution, on the one hand, the slide rail 14 defines the lifting and lowering trajectory of the limit testing mechanism 3, which can further improve the stability and smoothness during the lifting and lowering process of the limit testing mechanism 3. On the other hand, this structure can play a limiting role, which is the same as the role of the ascending and descending groove, and can further limit the limit testing mechanism 3 and the lifting seat 11 to prevent the lifting seat 11 from rotating, and can better convert the rotational force of the driving lead screw 10 into the linear force of the lifting seat 11. This structure is also to ensure the stable limiting and fixing effect on the water pump body 6 to ensure the detection accuracy.

[0075] Such as Figure 6 、 Figure 7 And Figure 8As shown, in a preferred embodiment of the present invention, the elastic connecting member includes a plurality of sleeves 302 that are spaced apart and vertically arranged on the lower surface of the assembly plate 312. The bottom of each sleeve 302 is respectively provided with a matching piston rod 303. The bottoms of the piston rods 303 are respectively fixedly assembled on the upper surface of the limiting plate 305 and are arranged around the positioning hole 313. A spring column 304 is sleeved on each piston rod 303. The lower end of the spring column 304 is fixed on the limiting plate 305, and its upper end is fixed on the bottom of the corresponding sleeve 302.

[0076] In the above solution, on the one hand, the elastic connecting member serves to assemble the limiting plate on the assembly plate, and on the other hand, it can buffer the limiting plate when clamping and limiting the water pump body, extend the clamping and limiting process, so as to ensure the stability after limiting and the protection of the water pump body 5.

[0077] In summary, when the automatic water pump seal runout detection device provided by the present invention is in use, on the one hand, the water pump support mechanism 7 cooperates with the limit test mechanism 3 to stably limit and support the water pump body 6 to be detected. On the other hand, the misplacement proximity switch and the anti-misplacement photoelectric switch 4 are used for dual misplacement prevention functions to ensure that the water pump support mechanism 7 and the water pump body 6 are assembled in the preset positions, ensure the stable and precise limit fixation of the limit test mechanism 3 on the water pump body 6, thereby ensuring the water pump body 6; the above measures are used to ensure the accuracy of the automatic detection of the water pump seal runout of the water pump body 6.

[0078] As Figure 11 shown, the present invention also provides an automatic water pump seal runout detection method, and the method includes:

[0079] Using the water pump support mechanism 7 to limit and support the water pump body 6 to be detected from the bottom.

[0080] A displacement sensor 8 with a detection head in contact with the reference surface preset at the bottom of the water pump body 6 is arranged below the water pump body 6.

[0081] Driving the limit test mechanism 3 to descend to clamp and limit the water pump body 6 from the top of the water pump body 6, and driving the top rotating shaft 16 of the water pump body 6 to perform a rotation test.

[0082] Using the displacement sensor 8 to respectively detect the height of the water pump body 6 in the initial state and the runout value of the reference surface at the bottom in the detection state.

[0083] In the above solution, when the method is in use, the water pump body 6 to be detected is placed on the water pump support mechanism 7, which supports and limits it from its bottom, and ensures that the rotating shaft 16 on the water pump body 6 is in a vertical state. Then, the limit testing mechanism 3 is driven to descend so that the limit plate 305 limits the water pump body 6 from its top, and cooperates with the water pump support mechanism 7 to stably limit and support the water pump body. Then, the clamping cylinder 309 is used to clamp and fix the top of the rotating shaft 16 on the water pump body 6, and a rotation test is carried out under the driving action of the driving motor 306. The displacement sensor 8 at the bottom of the water pump body 6 can respectively detect the height of the water pump body 6 in the initial state and the jump value of the detection head of the displacement sensor 8 around the reference plane in the detection state to obtain the detection value. According to the detection value, the quality and quality of the water pump body 6 can be judged to sort it. The device of the present application can ensure the stability of the water pump body 6 during the rotation test of its rotating shaft, and cooperate with the displacement sensor 8 to ensure the accuracy of the water seal jump detection of the water pump body 6.

[0084] As Figure 12 shown, in a preferred embodiment of the present invention, before the driving limit testing mechanism 3 descends to clamp and limit the water pump body 6 from its top and drive the top rotating shaft 16 of the water pump body 6 to perform a rotation test, the method further includes: using a barcode scanner 5 to scan the two-dimensional code of the water pump body 6 to be detected to obtain and record the serial number information of the water pump body 6.

[0085] In a preferred embodiment of the present invention, after using the displacement sensor 8 to respectively detect the height of the water pump body 6 in the initial state and the jump value of the bottom reference plane in the detection state, the method further includes: binding the serial number information of the water pump body 6 to be detected with its detection data by the displacement sensor 8 one by one to form a data packet, and storing the data packet in the PLC data block so that the on-site MES can extract the data packet from the PLC data block by itself.

[0086] In summary, when the method provided by the present invention is in use, it can achieve the effect of automatically detecting the water pump body 6. On the one hand, the water pump support mechanism 7 cooperates with the limit testing mechanism 3 to stably limit and support the water pump body 6 to be detected. On the other hand, the misplacement proximity switch and the anti-misplacement photoelectric switch 4 are used for double misplacement prevention to ensure that the water pump support mechanism 7 and the water pump body 6 are assembled in the preset positions, and ensure the stable and accurate limit fixation of the limit testing mechanism 3 on the water pump body 6, thereby ensuring the water pump body 6; using the above measures to ensure the accuracy of the automatic detection of the water seal jump of the water pump body 6.

At the same time, press the double-start button; the measuring device starts to run automatically, the stepping motor drives the lead screw to descend, the motor drives the shaft to rotate, and the high-precision displacement sensor at the bottom measures in real time. After the measurement is completed, the mechanism automatically moves up, and the data is displayed on the touch screen 20; and the process data of each shift is counted for SPC statistics. The operator takes out the inspected workpiece and sorts the workpiece according to the measurement results displayed on the touch screen; the workpiece QR code information is bound to the workpiece measurement data one by one, and the data is stored in the PLC data block, and the on-site MES extracts the data from the PLC data block by itself; the operation proceeds to the next cycle.
