Description

Technical Field

[0001] This invention relates to the field of connecting rod roughness detection technology, specifically to a fully dynamic light source projection connecting rod detection device. Background Technology

[0002] With the rapid development of the automotive industry, various shock absorbers, pneumatic components, brakes and other devices are widely used. Among the core components of these devices is the connecting rod. After processing, welding and chrome plating, the connecting rod not only requires high dimensional accuracy, but also a smooth and defect-free surface. However, due to the influence of electroplating, the surface of the connecting rod often has protrusions. Therefore, before the connecting rod is put into use, it is necessary to use visual inspection equipment to inspect the shape and surface roughness of the connecting rod.

[0003] Currently, before testing the connecting rods, the surface of the connecting rods is often covered with oil stains. In order not to affect the testing accuracy, the surface of the connecting rods needs to be wiped clean manually before testing. However, manual wiping is still incomplete and inefficient, which directly affects the testing efficiency of surface roughness testing of large batches of connecting rods and is easy to damage the electroplated surface.

[0004] In view of this, in order to improve the above-mentioned technical problems, the present invention provides a fully dynamic light source projection type connecting rod detection device, which improves the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by this invention is that before the connecting rod is inspected, the surface of the connecting rod is often covered with oil stains. In order not to affect the inspection accuracy, the surface of the connecting rod needs to be wiped clean manually before inspection. However, manual wiping will eventually miss some parts and is not efficient. This directly affects the inspection efficiency of surface roughness inspection of a large number of connecting rods and is easy to damage the electroplated surface.

[0006] The present invention provides a fully dynamic light source projection type connecting rod detection device, including an operating table. The fully dynamic light source projection type connecting rod detection device further includes: a first support plate, a support rack, a hydraulic mechanism, a cleaning unit, a detection unit, a motor, and a second support plate.

[0007] The No. 1 support plate is fixedly installed on one side of the operating table;

[0008] The shelf is located on one side of the first support plate and is fixedly installed on the operating table. The shelf includes an arc-shaped support plate and is used to place connecting rods.

[0009] The hydraulic mechanism is fixedly installed on the No. 1 support plate, and the hydraulic mechanism is located between the shelf and the No. 1 support plate;

[0010] The cleaning unit is installed on the operating table and is located on the side of the support frame away from the hydraulic mechanism. The cleaning unit is used to scrape off oil stains on the surface of the connecting rod.

[0011] The detection unit is installed on the operating table and is located on the side of the cleaning unit away from the shelf. The detection unit is used to detect whether there is an error in the shape and progress of the connecting rod.

[0012] The motor output shaft is connected to the detection unit, and the motor is located on the side of the detection unit away from the cleaning unit. The motor provides power to the detection unit.

[0013] The second support plate is fixedly connected to the motor, and the second support plate is located on the side of the motor away from the detection unit. The second support plate is fixedly installed on the operating table.

[0014] The automatic cleaning of oil stains on the surface of the connecting rod is achieved through the cooperation of the hydraulic mechanism, the support rack and the cleaning unit. This improves the automation level of the testing equipment, the accuracy and efficiency of the surface roughness test of the connecting rod, and reduces the damage to the electroplated layer on the surface of the connecting rod during cleaning. Furthermore, the streamlined design of the cleaning unit and the testing unit further improves the testing efficiency.

[0015] Preferably, the cleaning unit includes: a first support column, a cleaning bucket, a spiral frame, and a first airbag;

[0016] The No. 1 support column is fixedly installed on the operating table;

[0017] The cleaning bucket is fixedly installed on the No. 1 support column;

[0018] The spiral frame is fixedly installed in a spiral shape on the inner surface of the cleaning bucket;

[0019] The No. 1 airbag is fixedly installed on the spiral frame in a spiral shape.

[0020] Preferably, the components include: No. 2 support column, No. 3 support plate, telescopic rod, arc plate, mounting rod, laser emitter, camera, and connecting frame;

[0021] The second support column is fixedly installed on the operating table;

[0022] The No. 3 support plate is fixedly installed on the No. 2 support column, and the No. 3 support plate is in the shape of a "V".

[0023] The telescopic rods are provided in two and symmetrically arranged on the upper surface of the No. 3 support plate, and the telescopic rods are fixedly connected to the No. 3 support plate;

[0024] Two arc-shaped plates are provided, and the arc-shaped plates are fixedly connected to the end of the telescopic rod away from the third support plate;

[0025] The mounting rod is located on the center side of the telescopic rod away from the No. 3 support plate, and the mounting rod is fixedly connected to the telescopic rod.

[0026] The laser emitter is fixedly mounted on the mounting rod, with the emitting end of the laser emitter facing the second support plate;

[0027] The camera is fixedly mounted on the second support plate, and the camera is positioned opposite to the laser emitter.

[0028] The connecting frame is fixedly connected to the motor output shaft, and the connecting frame includes a retaining ring.

[0029] Preferably, springs are provided on both sides of the telescopic rod, with one end of the spring fixedly connected to the No. 3 support plate and the other end fixedly connected to the arc-shaped plate.

[0030] When testing the surface roughness of the connecting rod, the operator first places the connecting rod to be tested on the arc-shaped support plate of the shelf, ensuring the connecting rod is in contact with the arc-shaped support plate. Then, the operator controls the hydraulic mechanism according to the controller. The output end of the hydraulic mechanism extends and pushes the connecting rod located on the arc-shaped support plate into the cleaning bucket. The connecting rod, once inside the cleaning bucket, compresses the first air bladder, causing the first air bladder to fit tightly against the surface of the connecting rod. As the output end of the hydraulic mechanism continues to exert a thrust on the connecting rod, it gradually moves towards the arc-shaped plate within the cleaning bucket. From the moment the connecting rod enters the cleaning bucket from one end, as it gradually moves towards the arc-shaped plate, the surface of the connecting rod is first scratched by the first air bladder near the end of the arc-shaped support plate. As the connecting rod continues to move, and because the spiral frame is fixed to the inner wall of the cleaning bucket in a spiral shape, there is a pitch between the spiral frames. Since an airbag is fixed on the spiral frame, and the airbag is also fixed to the spiral frame in a spiral shape, the airbag forms multiple cleaning rings in the cleaning bucket. Therefore, when the connecting rod enters the cleaning bucket, the connecting rod is repeatedly scraped by the multiple cleaning rings formed by the airbag, thereby cleaning the oil stains on the surface of the connecting rod multiple times. The oil stains scraped off by the airbag fall into the pitch of the airbag, i.e., the spiral frame, so that the surface of the connecting rod entering the detection unit is clean and will not have a large amount of oil stains adhering to it, thereby improving the detection accuracy of the surface roughness of the connecting rod.

[0031] After the connecting rod is cleaned, due to the continuous thrust from the output end of the hydraulic mechanism, the connecting rod detaches from the cleaning bucket and enters the inspection frame formed by the two arc-shaped plates. During the process of the connecting rod detaching from the cleaning bucket, the end of the connecting rod that detaches from the cleaning bucket first enters the fixing ring of the connecting frame. The operator controls the motor to start through the controller, the motor output shaft rotates and the connecting frame rotates, and the rotation of the connecting frame drives the connecting rod to rotate.

[0032] When the connecting rod rotates, if the surface roughness of the connecting rod meets the actual production requirements and there is no shape progress error on the surface of the connecting rod, then when the connecting rod rotates, due to its smooth surface, the arc plate moves to both sides with a small amplitude, the deformation of the telescopic rod and the spring is small, the telescopic stroke of the telescopic rod is short, the moving stroke of the mounting rod with the telescopic rod is small, the moving amplitude of the laser emitter with the mounting rod is small, that is, the change in the amplitude of the light source emitted by the laser emitter is small, the change in the amplitude of the laser emitter light source received and identified by the camera is small, and the indicator light on the camera does not flash;

[0033] When the connecting rod rotates, if the surface roughness of the connecting rod does not meet the actual production requirements and there is a shape progress error on the surface of the connecting rod, the protruding part of its surface will squeeze the arc plate to both sides when the connecting rod rotates. The arc plate moves to both sides, and the arc plate jumps a large amplitude during the rotation of the connecting rod. This results in a large deformation of the telescopic rod and the spring, a long extension and retraction stroke of the telescopic rod, a large stroke of the mounting rod as the telescopic rod moves, and a large amplitude of movement of the laser emitter as the mounting rod moves. In other words, the amplitude of the light source emitted by the laser emitter changes a large amount, and the amplitude of the amplitude of the laser emitter light source received and identified by the camera changes a large amount. The indicator light on the camera flashes. At this time, the staff judges that the surface roughness of this connecting rod does not meet the actual production requirements based on the flashing indicator light of the camera, and makes relevant marks on this connecting rod, thereby completing the detection of the surface roughness of the connecting rod.

[0034] Preferably, the centers of the arc-shaped support plate, the cleaning bucket, the arc plate, and the fixing ring are on a straight line.

[0035] It can calibrate the workpiece during inspection, ensuring that the connecting rod can enter the cleaning bucket, arc plate and fixing ring normally without deviation, which facilitates the inspection of the connecting rod.

[0036] Preferably, the spiral frame has an oil passage hole, the wall of the oil passage hole is in contact with the inner wall of the cleaning bucket, and the inner diameter of the cleaning bucket gradually decreases from the end near the support frame to the end away from the support frame.

[0037] Because the spiral frame is fixed to the inner wall of the cleaning bucket in a spiral shape, there is a pitch between the spiral frames. Since an airbag is fixed on the spiral frame, and the airbag is also fixed to the spiral frame in a spiral shape, the airbag forms multiple cleaning rings in the cleaning bucket. Therefore, when the connecting rod enters the cleaning bucket, the connecting rod is repeatedly scraped by the multiple cleaning rings formed by the airbag, and the oil on the connecting rod falls into the pitch formed by the spiral frame.

[0038] Because the inner diameter of the cleaning bucket gradually decreases from the end near the shelf to the end away from the shelf, the inner wall of the cleaning bucket is inclined. The height of the inner wall of the cleaning bucket from the end near the shelf is lower than the height of the end away from the shelf. The oil falling in the pitch formed by the screw frame flows out through the oil passage along the inner wall of the cleaning bucket towards the end near the shelf.

[0039] Meanwhile, as the inner diameter of the cleaning bucket gradually decreases from the end closest to the shelf to the end furthest from the shelf, the squeezing force of the connecting rod on the No. 1 airbag gradually increases as the connecting rod moves under the push of the hydraulic mechanism output end. Consequently, the scraping force of the No. 1 airbag on the connecting rod gradually increases. In other words, the No. 1 airbag forms a multi-stage scraping and cleaning process on the oil stains on the surface of the connecting rod, further ensuring the cleanliness of the connecting rod surface and guaranteeing the testing effect.

[0040] Preferably, the operating table is provided with an oil guide groove, which is located below the end of the cleaning bucket near the shelf.

[0041] The oil flows through the oil passage along the inner wall of the cleaning bucket towards the end near the shelf and then falls into the oil guide trough, making it easy to collect and clean the falling oil and impurities.

[0042] Preferably, a second airbag is fixed to the inner wall of the fixing ring. The second airbag is annular, and an air pump is connected to the second airbag via an air tube. The air pump is located on the operating table.

[0043] After the end of the connecting rod away from the cleaning bucket enters the fixing ring, the staff controls the air pump to work through the controller. The air pump inputs gas into the second air bladder through the air tube. The second air bladder inflates and fits tightly with the connecting rod, fixing the connecting rod in the fixing ring, which facilitates the roughness detection of the connecting rod.

[0044] After the connecting rod is tested, the staff uses the controller to control the air pump to extract the gas from the second airbag. The second airbag contracts and detaches from the connecting rod, and the connecting rod is no longer fixed by the retaining ring, making it easier to remove the connecting rod after the test is completed.

[0045] Preferably, the shelf, hydraulic mechanism, cleaning unit, detection unit and motor are provided in multiple sets.

[0046] By equipping multiple sets of the support rack, hydraulic mechanism, cleaning unit, detection unit and motor, multiple connecting rods can be detected simultaneously, improving detection efficiency.

[0047] The beneficial effects of this invention are as follows:

[0048] 1. The present invention provides a fully dynamic light source projection type connecting rod detection device, which automatically cleans oil stains on the surface of the connecting rod through the cooperation of hydraulic mechanism, support frame and cleaning unit. It improves the automation level of detection equipment, improves the detection accuracy and efficiency of connecting rod surface roughness detection, reduces damage to the electroplated layer on the surface of the connecting rod during cleaning, and further improves detection efficiency by the streamlined design of cleaning unit and detection unit.

[0049] 2. The present invention provides a fully dynamic light source projection type connecting rod detection device, which uses a first airbag fixed on a spiral frame. The first airbag is also spirally fixed on the spiral frame. The first airbag forms multiple cleaning rings in the cleaning bucket. Therefore, when the connecting rod enters the cleaning bucket, the connecting rod is repeatedly scraped by the multiple cleaning rings formed by the first airbag, thereby cleaning the oil stains on the surface of the connecting rod multiple times. The oil stains scraped off by the first airbag fall into the pitch of the first airbag, i.e., the spiral frame. Thus, the surface of the connecting rod entering the detection unit is clean and will not have a large amount of oil stains adhering to it, thereby improving the detection accuracy of the surface roughness of the connecting rod.

[0050] 3. The present invention provides a fully dynamic light source projection type connecting rod detection device. By setting up a detection unit, when the connecting rod first separates from one end of the cleaning bucket and enters the fixing ring of the connecting frame, the operator controls the motor to start through the controller. The motor output shaft rotates and drives the connecting rod located on the arc plate to rotate. When the connecting rod rotates, the amplitude of the dynamic light source emitted by the laser emitter set below the arc plate is received and identified by the camera to determine whether the roughness of the connecting rod can meet the actual production requirements, thereby completing the detection of the surface roughness of the connecting rod.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] like Figure 1 and Figure 2 As shown, the present invention provides a fully dynamic light source projection type connecting rod detection device, including an operating table 1. The fully dynamic light source projection type connecting rod detection device also includes: a first support plate 2, a support rack 3, a hydraulic mechanism 4, a cleaning unit 5, a detection unit 6, a motor 7, and a second support plate 8.

[0062] The first support plate 2 is fixedly installed on one side of the operating table 1;

[0063] The support rack 3 is located on one side of the first support plate 2 and is fixedly installed on the operating table 1. The support rack 3 includes an arc-shaped support plate 31 and is used to place the connecting rod.

[0064] The hydraulic mechanism 4 is fixedly installed on the first support plate 2, and the hydraulic mechanism 4 is located between the shelf 3 and the first support plate 2;

[0065] The cleaning unit 5 is installed on the operating table 1. The cleaning unit 5 is located on the side of the support frame 3 away from the hydraulic mechanism 4. The cleaning unit 5 is used to scrape the oil stains on the surface of the connecting rod.

[0066] The detection unit 6 is installed on the operating table 1. The detection unit 6 is located on the side of the cleaning unit 5 away from the shelf 3. The detection unit 6 is used to detect whether there is an error in the shape and progress of the connecting rod.

[0067] The output shaft of the motor 7 is connected to the detection unit 6. The motor 7 is located on the side of the detection unit 6 away from the cleaning unit 5. The motor 7 provides power to the detection unit 6.

[0068] The second support plate 8 is fixedly connected to the motor 7. The second support plate 8 is located on the side of the motor 7 away from the detection unit 6. The second support plate 8 is fixedly installed on the operating table 1.

[0069] By adopting the above technical solution, when detecting the surface roughness of the connecting rod, the operator first places the connecting rod to be tested on the support frame 3. Then, the operator controls the hydraulic mechanism 4 to work according to the controller. The output end of the hydraulic mechanism 4 extends and pushes the connecting rod located on the support frame 3 into the cleaning unit 5. As the output end of the hydraulic mechanism 4 continuously generates a thrust on the connecting rod, the connecting rod moves towards the detection unit 6 in the cleaning unit 5 and is cleaned multiple times by the cleaning elements in the cleaning unit 5. The oil stains on the surface of the connecting rod are scraped by the cleaning elements in the cleaning unit 5, so that the surface of the connecting rod entering the detection unit 6 is clean and will not have a large amount of oil stains adhering to it, thereby improving the detection accuracy of the surface roughness of the connecting rod.

[0070] After the connecting rod passes through the cleaning unit 5 and enters the detection unit 6, the staff controls the motor 7 to start through the controller. The output shaft of the motor 7 rotates and drives the detection unit 6 to work. The transmission element in the detection unit 6 drives the connecting rod to rotate. When the connecting rod rotates, the staff observes the repeated jumping amplitude of the light source of the light element in the detection unit 6 to determine whether its surface roughness meets the actual production requirements, thereby completing the detection of the surface roughness of the connecting rod.

[0071] Compared to existing technologies, manually wiping the oil stains on the surface of the connecting rod not only damages the electroplated layer but also easily misses some, resulting in low wiping efficiency and directly affecting the detection efficiency of surface roughness testing for large batches of connecting rods, this invention achieves automatic cleaning of oil stains on the surface of the connecting rod through the cooperation of the hydraulic mechanism 4, the support frame 3, and the cleaning unit 5. This improves the automation level of the testing equipment, enhances the detection accuracy and efficiency of surface roughness testing of the connecting rod, reduces damage to the electroplated layer of the connecting rod surface during cleaning, and further improves the detection efficiency by streamlining the design of the cleaning unit 5 and the detection unit 6.

[0072] like Figures 1 to 7 As shown, in a specific embodiment of the present invention, the cleaning unit 5 includes: a first support column 51, a cleaning bucket 52, a spiral frame 53, and a first airbag 54.

[0073] The first support column 51 is fixedly installed on the operating table 1;

[0074] The cleaning bucket 52 is fixedly installed on the first support column 51;

[0075] The spiral frame 53 is fixedly installed in a spiral shape on the inner surface of the cleaning bucket 52;

[0076] The No. 1 airbag 54 is fixedly installed on the spiral frame 53 in a spiral shape;

[0077] The detection unit 6 includes: a second support column 61, a third support plate 62, a telescopic rod 63, an arc plate 64, a mounting rod 65, a laser emitter 66, a camera 67, and a connecting frame 68.

[0078] The second support column 61 is fixedly installed on the operating table 1;

[0079] The third support plate 62 is fixedly installed on the second support column 61, and the third support plate 62 is in the shape of a "V".

[0080] Two telescopic rods 63 are provided and symmetrically arranged on the upper surface of the third support plate 62, and the telescopic rods 63 are fixedly connected to the third support plate 62.

[0081] Two arc-shaped plates 64 are provided, and the arc-shaped plates 64 are fixedly connected to the end of the telescopic rod 63 away from the third support plate 62;

[0082] The mounting rod 65 is located on the center side of the telescopic rod 63 away from the third support plate 62, and the mounting rod 65 is fixedly connected to the telescopic rod 63.

[0083] The laser emitter 66 is fixedly installed on the mounting rod 65, and the emitting end of the laser emitter 66 faces the second support plate 8;

[0084] The camera 67 is fixedly mounted on the second support plate 8, and the camera 67 is arranged opposite to the laser emitter 66;

[0085] The connecting frame 68 is fixedly connected to the output shaft of the motor 7, and the connecting frame 68 includes a retaining ring 681.

[0086] Springs 12 are provided on both sides of the telescopic rod 63. One end of the spring 12 is fixedly connected to the third support plate 62, and the other end is fixedly connected to the arc plate 64.

[0087] By adopting the above technical solution, when testing the surface roughness of the connecting rod, the operator first places the connecting rod to be tested on the arc-shaped support plate 31 of the support frame 3, with the connecting rod in contact with the arc-shaped support plate 31. Then, the operator controls the hydraulic mechanism 4 according to the controller. The output end of the hydraulic mechanism 4 extends and pushes the connecting rod located on the arc-shaped support plate 31 into the cleaning tank 52. The connecting rod entering the cleaning tank 52 compresses the first air bladder 54, which is in close contact with the surface of the connecting rod. As the output end of the hydraulic mechanism 4 continues to generate thrust on the connecting rod, the connecting rod gradually moves towards the arc-shaped plate 64 in the cleaning tank 52. From the moment the connecting rod enters the cleaning tank 52 from one end, as it gradually moves towards the arc-shaped plate 64, the surface of the connecting rod first receives the first air bladder near the end of the arc-shaped support plate 31. The connecting rod is scraped by the airbag 54, and then as the connecting rod continues to move, and because the spiral frame 53 is fixed to the inner wall of the cleaning bucket 52 in a spiral shape, there is a pitch between the spiral frames 53. Since the first airbag 54 is fixed on the spiral frame 53, and the first airbag 54 is also fixed to the spiral frame 53 in a spiral shape, the first airbag 54 forms multiple cleaning rings in the cleaning bucket 52. Therefore, when the connecting rod enters the cleaning bucket 52, the connecting rod is scraped by the multiple cleaning rings formed by the first airbag 54, thereby cleaning the oil stains on the surface of the connecting rod multiple times. The oil stains scraped off by the first airbag 54 fall into the pitch of the first airbag 54, i.e., the spiral frame 53, so that the surface of the connecting rod entering the detection unit 6 is clean and will not have a large amount of oil stains adhering to it, thereby improving the detection accuracy of the surface roughness of the connecting rod.

[0088] After the connecting rod is cleaned, due to the continuous thrust from the output end of the hydraulic mechanism 4, the connecting rod detaches from the cleaning bucket 52 and enters the detection frame formed by the two arc plates 64. During the process of the connecting rod detaching from the cleaning bucket 52, the end of the connecting rod that detaches from the cleaning bucket 52 first enters the fixing ring 681 of the connecting frame 68. The operator controls the motor 7 to start through the controller. The output shaft of the motor 7 rotates and the connecting frame 68 rotates, which in turn drives the connecting rod to rotate.

[0089] When the connecting rod rotates, if the surface roughness of the connecting rod meets the actual production requirements and there is no shape progress error on the surface of the connecting rod, then when the connecting rod rotates, due to its smooth surface, the arc plate 64 moves to both sides with a small amplitude, the deformation of the telescopic rod 63 and the spring 12 is small, the telescopic stroke of the telescopic rod 63 is short, the moving stroke of the mounting rod 65 with the telescopic rod 63 is small, the moving amplitude of the laser emitter 66 with the mounting rod 65 is small, that is, the change in the amplitude of the light source emitted by the laser emitter 66 is small, the change in the amplitude of the light source of the laser emitter 66 received and identified by the camera 67 is small, and the indicator light on the camera 67 does not flash;

[0090] When the connecting rod rotates, if the surface roughness of the connecting rod does not meet the actual production requirements and there is a shape progress error on the surface of the connecting rod, the protruding part of its surface will squeeze the arc plate 64 to both sides when the connecting rod rotates. The arc plate 64 moves to both sides. During the rotation of the connecting rod, the arc plate 64 jumps a large amplitude, so the deformation of the telescopic rod 63 and the spring 12 is large. The telescopic stroke of the telescopic rod 63 is long, and the installation rod 65 moves a large stroke with the telescopic rod 63. The laser emitter 66 moves a large amplitude with the installation rod 65, that is, the light source emitted by the laser emitter 66 jumps a large amplitude. The laser emitter 66 light source received and identified by the camera 67 jumps a large amplitude, and the indicator light on the camera 67 flashes. At this time, the staff judges that the surface roughness of this connecting rod does not meet the actual production requirements based on the flashing indicator light of the camera 67, and makes relevant marks on this connecting rod to complete the detection of the surface roughness of the connecting rod.

[0091] Therefore, the present invention completes the automatic cleaning of oil stains on the surface of the connecting rod through the cooperation of the hydraulic mechanism 4, the support frame 3 and the cleaning unit 5. This improves the automation level of the testing equipment, as well as the detection accuracy and efficiency of the surface roughness detection of the connecting rod. The softness of the airbag also reduces the damage to the electroplated layer on the surface of the connecting rod during cleaning. Furthermore, the streamlined design of the cleaning unit 5 and the detection unit 6 further improves the detection efficiency.

[0092] like Figure 3 As shown, in a specific embodiment of the present invention, the centers of the arc-shaped support plate 31, the cleaning bucket 52, the arc-shaped plate 64 and the fixing ring 681 are on a straight line.

[0093] By adopting the above technical solution, and by ensuring that the centers of the arc-shaped support plate 31, the cleaning bucket 52, the arc-shaped plate 64, and the fixing ring 681 are on a straight line, the workpiece can be calibrated during inspection, ensuring that the connecting rod can enter the cleaning bucket 52, the arc-shaped plate 64, and the fixing ring 681 normally without deviation, which facilitates the inspection of the connecting rod.

[0094] like Figure 4 and Figure 5 As shown, in a specific embodiment of the present invention, the spiral frame 53 is provided with an oil passage hole 9, the wall of the oil passage hole 9 is in contact with the inner wall of the cleaning bucket 52, and the inner diameter of the cleaning bucket 52 gradually decreases from the end near the support frame 3 to the end away from the support frame 3.

[0095] By adopting the above technical solution, since the spiral frame 53 is fixed to the inner wall of the cleaning bucket 52 in a spiral shape, there is a pitch between the spiral frames 53. Since the first airbag 54 is fixed on the spiral frame 53, and the first airbag 54 is also fixed to the spiral frame 53 in a spiral shape, the first airbag 54 forms multiple cleaning rings in the cleaning bucket 52. Therefore, when the connecting rod enters the cleaning bucket 52, the connecting rod is repeatedly scraped by the multiple cleaning rings formed by the first airbag 54, and the oil on the connecting rod falls into the pitch formed by the spiral frame 53.

[0096] Since the inner diameter of the cleaning bucket 52 gradually decreases from the end near the support 3 to the end away from the support 3, the inner wall of the cleaning bucket 52 is inclined. The height of the inner wall of the cleaning bucket 52 from the end near the support 3 is lower than the height of the end away from the support 3. The oil falling in the pitch formed by the screw frame 53 flows and is discharged along the inner wall of the cleaning bucket 52 towards the end near the support 3 through the oil passage 9.

[0097] Meanwhile, as the inner diameter of the cleaning bucket 52 gradually decreases from the end closest to the support rack 3 to the end furthest from the support rack 3, the squeezing force of the connecting rod on the first airbag 54 gradually increases as the connecting rod moves under the push of the output end of the hydraulic mechanism 4. Consequently, the scraping force of the first airbag 54 on the connecting rod gradually increases. That is, the first airbag 54 forms a multi-stage scraping cleaning of the oil stains on the surface of the connecting rod, further ensuring the cleanliness of the surface of the connecting rod and ensuring the testing effect.

[0098] like Figure 1 As shown, in a specific embodiment of the present invention, an oil guide groove 10 is provided on the operating table 1, and the oil guide groove 10 is located below the cleaning bucket 52 near the end of the support frame 3.

[0099] By adopting the above technical solution, the oil flows through the oil passage 9 along the inner wall of the cleaning bucket 52 towards the end near the support rack 3 and then falls into the oil guide trough 10, which facilitates the collection and cleaning of the falling oil and impurities.

[0100] like Figure 2 and Figure 6 As shown, in a specific embodiment of the present invention, a second airbag 11 is fixedly connected to the inner wall of the fixing ring 681. The second airbag 11 is annular, and an air pump is connected to the second airbag 11 through an air tube. The air pump is set on the operating table 1.

[0101] By adopting the above technical solution, when the end of the connecting rod away from the cleaning bucket 52 enters the fixing ring 681, the staff controls the air pump to work through the controller. The air pump inputs gas into the second air bag 11 through the air pipe. The second air bag 11 expands. The expanded second air bag 11 fits tightly with the connecting rod, fixing the connecting rod located in the fixing ring 681, which facilitates the roughness detection of the connecting rod.

[0102] After the connecting rod is tested, the staff uses the controller to control the air pump to extract the gas from the second airbag 11. The second airbag 11 contracts and detaches from the connecting rod, and the connecting rod is no longer fixed by the fixing ring 681, making it easier to remove the connecting rod after the test is completed.

[0103] like Figure 1 As shown, in a specific embodiment of the present invention, the shelf 3, hydraulic mechanism 4, cleaning unit 5, detection unit 6 and motor 7 are provided in multiple sets;

[0104] By adopting the above technical solution, and by equipping multiple sets of the support rack 3, hydraulic mechanism 4, cleaning unit 5, detection unit 6 and motor 7, multiple connecting rods can be detected simultaneously, thereby improving detection efficiency.

[0105] Working principle:

[0106] When testing the surface roughness of the connecting rod, the operator first places the connecting rod to be tested on the arc-shaped support plate 31 of the support rack 3, with the connecting rod in contact with the arc-shaped support plate 31. Then, the operator controls the hydraulic mechanism 4 according to the controller. The output end of the hydraulic mechanism 4 extends and pushes the connecting rod located on the arc-shaped support plate 31 into the cleaning tank 52. The connecting rod entering the cleaning tank 52 compresses the first airbag 54, and the first airbag 54 is in close contact with the surface of the connecting rod. As the output end of the hydraulic mechanism 4 continues to push the connecting rod, the connecting rod gradually moves towards the arc-shaped plate 64 in the cleaning tank 52. From the moment the connecting rod enters the cleaning tank 52 from one end, as it gradually moves towards the arc-shaped plate 64, the surface of the connecting rod is first scratched by the first airbag 54 near the end of the arc-shaped support plate 31. As the connecting rod continues to move, and because the spiral frame 53 is fixed to the inner wall of the cleaning bucket 52 in a spiral shape, there is a pitch between the spiral frames 53. Since an airbag 54 is fixed on the spiral frame 53, and the airbag 54 is also fixed to the spiral frame 53 in a spiral shape, the airbag 54 forms multiple cleaning rings in the cleaning bucket 52. Therefore, when the connecting rod enters the cleaning bucket 52, the connecting rod is repeatedly scraped by the multiple cleaning rings formed by the airbag 54, thereby cleaning the oil stains on the surface of the connecting rod multiple times. The oil stains scraped off by the airbag 54 fall into the pitch of the airbag 54, i.e., the spiral frame 53, so that the surface of the connecting rod entering the detection unit 6 is clean and will not have a large amount of oil stains adhering to it, thereby improving the detection accuracy of the surface roughness of the connecting rod.

[0107] After the connecting rod is cleaned, due to the continuous thrust from the output end of the hydraulic mechanism 4, the connecting rod detaches from the cleaning bucket 52 and enters the detection frame formed by the two arc-shaped plates 64. During the process of the connecting rod detaching from the cleaning bucket 52, the end of the connecting rod that detaches from the cleaning bucket 52 first enters the fixing ring 681 of the connecting frame 68. The operator controls the air pump to work through the controller. The air pump inputs gas into the second airbag 11 through the air pipe. The second airbag 11 inflates. The inflated second airbag 11 fits tightly with the connecting rod, fixing the connecting rod located in the fixing ring 681. Then, the operator controls the motor 7 to start through the controller. The output shaft of the motor 7 rotates and the connecting frame 68 rotates. The rotation of the connecting frame 68 drives the connecting rod to rotate.

[0108] When the connecting rod rotates, if the surface roughness of the connecting rod meets the actual production requirements and there is no shape progress error on the surface of the connecting rod, then when the connecting rod rotates, due to its smooth surface, the arc plate 64 moves to both sides with a small amplitude, the deformation of the telescopic rod 63 and the spring 12 is small, the telescopic stroke of the telescopic rod 63 is short, the moving stroke of the mounting rod 65 with the telescopic rod 63 is small, the moving amplitude of the laser emitter 66 with the mounting rod 65 is small, that is, the change in the amplitude of the light source emitted by the laser emitter 66 is small, the change in the amplitude of the light source of the laser emitter 66 received and identified by the camera 67 is small, and the indicator light on the camera 67 does not flash;

[0109] When the connecting rod rotates, if the surface roughness of the connecting rod does not meet the actual production requirements and there is a shape progress error on the surface of the connecting rod, the protruding part of its surface will squeeze the arc plate 64 to both sides when the connecting rod rotates. The arc plate 64 moves to both sides. During the rotation of the connecting rod, the arc plate 64 jumps a large amplitude, so the deformation of the telescopic rod 63 and the spring 12 is large. The telescopic stroke of the telescopic rod 63 is long, and the installation rod 65 moves a large stroke with the telescopic rod 63. The laser emitter 66 moves a large amplitude with the installation rod 65, that is, the light source emitted by the laser emitter 66 jumps a large amplitude. The laser emitter 66 light source received and identified by the camera 67 jumps a large amplitude, and the indicator light on the camera 67 flashes. At this time, the staff judges that the surface roughness of this connecting rod does not meet the actual production requirements based on the flashing indicator light of the camera 67, and makes relevant marks on this connecting rod to complete the detection of the surface roughness of the connecting rod.

[0110] After the connecting rod is tested, the staff uses the controller to control the air pump to extract the gas from the second airbag 11. The second airbag 11 contracts and detaches from the connecting rod, and the connecting rod is no longer fixed by the fixing ring 681, making it easier to remove the connecting rod after the test is completed.

[0111] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
