[0014] The present invention also provides a fully automatic detection method for a water pump bearing sealing groove, comprising the following detection steps:

[0015] S1. Benchmarking:

[0016] After the S1.1 device is started, the host computer issues a command, and the first transport station transports the standard parts from the placement position to the measuring table of the positive and negative reference end measuring station of the water pump bearing;

[0017] S1.2 The positive and negative reference end measuring station of the water pump bearing measures the positive reference end groove size of the standard part and feeds back the measurement data to the host computer for pre-storage;

[0018] S1.3 The second transport station transports the standard part to the measuring table of the first water pump bearing seal groove measuring station, measures the seal groove size of the positive reference end of the standard part, and feeds back the measurement data to the host computer for pre-storage;

[0021] S2. Test piece inspection:

[0022] S2.1 The feeding station feeds the test piece, and the second transport station transports the test piece on the feeding station to the measuring table of the positive and negative reference end measuring station of the water pump bearing;

[0023] S2.2 The water pump bearing positive and negative reference end measurement station measures the reference end groove size of the test piece and feeds back the measurement data to the host computer.

[0024] S2.3 The second transport station transports the test piece to the measuring table of the first water pump bearing seal groove measuring station, measures the size of the positive reference end seal groove of the test piece, and feeds the measurement data back to the host computer.

[0025] S2.4 The second transport station transports the workpiece to the measuring table of the second water pump bearing seal groove measuring station. During the transportation, the workpiece to be tested is turned over so that the counter-reference end of the workpiece to be tested faces upward. The second water pump bearing seal groove measuring station measures the counter-reference end seal groove size of the workpiece to be tested and feeds the measurement data back to the host computer.

[0030] By adopting the above technical solution, the present invention has the following beneficial effects:

[0031] (1) The present invention controls the second transport station through the host computer to transport the workpiece to be tested to the first and second water pump bearing seal groove measuring stations respectively; the first and second water pump bearing seal groove measuring stations respectively measure the seal groove dimensions of the positive and negative reference surfaces of the workpiece to be tested and feed back the measurement results to the host computer, and the host computer determines whether the workpiece to be tested is qualified based on the seal groove dimensions of the positive and negative reference surfaces of the pre-stored standard workpiece, thereby realizing full-process automated testing, significantly improving testing efficiency and accuracy, reducing manual intervention, and ensuring product quality.

[0032] (2) Since the size of the water pump bearing sealing groove is usually very small and the processing angle is relatively special, this not only increases the risk of "tool explosion" during machining, but also brings difficulties in measurement. The traditional detection method is usually carried out by sampling cutting and then projecting. This method cannot guarantee the processing quality of the entire batch of outer ring sealing grooves. The present invention drives the water pump bearing sealing groove measurement module to move downward through the eleventh driving unit, so that the bottom of the first measuring head assembly is inserted into the sealing groove of the workpiece to be measured; the thirteenth driving unit drives the first measuring head assembly to perform axial displacement, so that the measuring head at the bottom of the first measuring head assembly opens radially until it is in contact with the workpiece to be measured. The inner wall of the sealing groove is abutted; the first measuring unit measures the size of the sealing groove of the workpiece to be tested by detecting the axial displacement of the first measuring head assembly, and feeds back the measurement result to the host computer; compared with the traditional projection detection after sampling cutting, the present invention does not require any destructive treatment of the workpiece to be tested, and can achieve direct and efficient measurement of the size of the sealing groove of each workpiece; this not only avoids material waste caused by cutting, but also ensures that all products are subject to strict quality inspection, realizing true full inspection; it not only improves the accuracy and efficiency of detection, but also greatly reduces production costs, which is conducive to improving product quality and production stability.

[0033] (3) The fully automatic measuring device for the sealing groove of the water pump bearing of the present invention is provided with a feeding station which is connected to the upper computer for communication. When the upper computer issues a command, the feeding station starts automatically and feeds the workpiece to be measured into the measuring system, thus realizing automatic feeding and ensuring the high efficiency, accuracy and continuity of the entire measuring process, further improving the production automation level and detection efficiency.

[0034] (4) The present invention sets a water pump bearing positive and negative reference end measurement station between the feeding station and the first water pump bearing sealing groove measurement station, which can ensure that each part to be tested has completed the positive and negative position verification of the measuring end before entering the sealing groove measurement link, which can significantly improve the accuracy and reliability of the detection, prevent the subsequent detection and processing quality problems caused by the positive and negative position errors of the measuring end, and further improve the product quality and production efficiency.

[0035] (5) The measuring station of the positive and negative reference ends of the water pump bearing of the present invention is also provided with a first transport station for delivering the standard parts into the measuring system, thereby realizing automatic calibration of the standard parts and ensuring that the position and posture of the standard parts are consistent during each measurement, thereby improving the accuracy and repeatability of the measurement, effectively avoiding the position deviation caused by the manual placement of the standard parts, and further improving the reliability and efficiency of the entire detection process.

[0036] (6) A kicking station is provided below the first water pump bearing sealing groove measuring station and the second water pump bearing sealing groove measuring station of the present invention, which can remove unqualified workpieces in real time during the detection process to avoid the so-called "knife explosion" phenomenon during the processing process, resulting in the scrapping of the products being processed; by timely removing unqualified workpieces, these unqualified parts can be prevented from entering the subsequent processing links, thereby avoiding more material waste; in addition, this also ensures the correct installation of the sealing ring, prevents problems such as cover removal caused by unqualified parts, and ultimately extends the service life of the bearing and improves the overall production quality and efficiency.

[0037] (7) The fully automatic detection method for the water pump bearing sealing groove of the present invention is based on the fully automatic measuring device for the water pump bearing sealing groove, which can realize fully automatic calibration and fully automatic detection, reduce the number of quality inspection personnel, realize fully automatic detection, significantly improve the detection efficiency and production stability, and greatly reduce the production cost.

[0038] (8) The second transport station of step S1.4, step S2.4 and step S1.5 of the fully automatic detection method for the water pump bearing sealing groove of the present invention must be flipped during the transportation of standard parts and parts to be tested respectively, and the flipping angle is 180° to ensure that the corresponding reference ends of the standard parts and parts to be tested are facing the correct position when entering the next step to facilitate accurate measurement, thereby ensuring the consistency and accuracy of the measurement and further improving the reliability and efficiency of the detection.

[0039] (9) In step S2.2, step S2.3 and step S2.4 of the present invention, the data after detection must be fed back to the host computer; the host computer determines the reference end status of the test piece and whether it is qualified based on these data; based on the judgment result of the host computer, the system will execute the next step of operation, such as flipping during transportation, kicking out unqualified parts, unloading qualified parts, etc.; the automation and efficiency of the detection and processing process are ensured, and the stability and reliability of the overall production are improved.
