Description

Technical Field

[0001] The invention relates to the technical field of mechanical automation, and in particular to an automatic ultrasonic gear flaw detection workstation and a working method thereof. Background Art

[0002] As the core component of the automobile transmission, the welding quality of the shift gear and the coupling gear directly affects the shifting performance of the transmission. Since the welding process itself has many defect risks, such as cracks, spatter, pores, offset, undercut, etc., it affects the welding quality, and then affects the performance of the product, and even causes automobile accidents. Therefore, the gears after welding are generally inspected. The most common method of gear welding inspection is ultrasonic inspection. Ultrasonic inspection is a method of inspecting gear defects by using the characteristics of ultrasonic energy penetrating deep into the metal material and reflecting at the edge of the interface when entering from one section to another.

[0003] At present, the main method used for detection is artificial ultrasonic non-destructive testing. The following disadvantages are encountered in the use of artificial ultrasonic non-destructive testing: additional personnel are required, which increases labor costs; online synchronous detection cannot be achieved, and a batch of parts are often tested uniformly after welding; there are many uncontrollable factors, which may lead to false detection and missed detection; the cycle is slow and the efficiency is low; there are safety risks for operators, as the parts may not be completely cooled and cause burns, and the operator's skin may be damaged by long-term contact with the testing fluid.

[0057] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] The present invention relates to an automatic ultrasonic gear flaw detection workstation and a working method thereof. Compared with the prior art, the automatic flaw detection workstation designed by the present invention has reasonable design, simple structure, easy production and high automation, and can communicate and interact with a robot to realize fully automatic production. At the same time, the present invention also reduces labor costs, reduces the probability of missed detection and false detection of parts, and improves product quality.

[0059] An automatic ultrasonic gear flaw detection workstation, specifically, Figure 1 , 2 , as shown in 4, including:

[0060] The gear flaw detection device 100 includes a first frame 1, a second frame 2, a gear grabbing mechanism 3 and a flaw detection mechanism 4. The first frame 1 and the second frame 2 are connected side by side to provide support for the gear flaw detection device 100; the gear grabbing mechanism 3 is connected to the first frame 1 and is used to automatically grab the gear to be flawed; the flaw detection mechanism 4 is connected to the second frame 2 and is used to flaw-detect the gear;

[0061] The gear conveying device 200 is located on the side of the second platform 2 and is used to convey gears to be inspected and gears that have been inspected.

[0062] In fact, the first stand 1 and the second stand 2 together constitute the stand body of the automatic ultrasonic gear flaw detection device, providing support for the gear grasping mechanism 3 and the flaw detection mechanism 4; in this embodiment, the height of the first stand 1 is greater than that of the second stand 2, so as to reserve sufficient space for the gear grasping mechanism 3 to move up and down when performing gear flaw detection operations; the length of the first stand 1 is also greater than that of the second stand 2, so as to reserve space for the placement of the gear conveying device 200, and at the same time, it is also convenient for the gear grasping mechanism 3 to move back and forth between the flaw detection mechanism 4 and the gear conveying device 200 to transport gears.

[0063] Furthermore, pulleys and foot supports are installed at the bottom of the first stand 1 and the second stand 2. When the automatic ultrasonic gear flaw detection device needs to be moved, it can slide through the pulleys at the bottom of the first stand 1 and the second stand 2. When the automatic ultrasonic gear flaw detection device needs to operate stationary, it can be fixedly supported on the ground by the foot supports at the bottom of the first stand 1 and the second stand 2.

[0064] In this embodiment, Figure 4 As shown, the flaw detection mechanism 4 includes a water tank 41 and an ultrasonic probe 42. The ultrasonic probe 42 is installed in the middle position of the bottom of the water tank 41. The water tank 41 and the ultrasonic probe 42 work together to perform underwater ultrasonic flaw detection on the gears. Next to the flaw detection mechanism 4, a waste basket 12 is also connected to the second stand 2, and the waste basket 12 is used to collect gears that fail the flaw detection.

[0065] In some embodiments, the gear grabbing mechanism 3 is optimized, such as Figure 3 , 4 As shown, in this embodiment, the gear grabbing mechanism 3 includes a motion module 31 and a clamping module 32. The motion module 31 is connected to the first stand 1 and is used to control the movement of the clamping module 32; the clamping module 32 is connected to the motion module 31 and is used to clamp the gear.

[0066] During actual operation, the motion module 31 can control the movement of the clamping module 32. When the clamping module 32 moves to the top of the gear to be inspected, the clamping module 32 reaches down and accurately clamps the gear. Then the motion module 31 controls the clamping module 32 to carry the gear to the flaw detection mechanism 4. Finally, the motion module 31 controls the clamping module 32 and the gear to rotate to complete the flaw detection work.

[0067] In some embodiments, the motion module 31 is optimized, such as Figure 3 , 4As shown, in this embodiment, the motion module 31 includes an X-axis control module 311, a Z-axis control module 312 and a rotation control module 313. The X-axis control module 311 is connected to the first platform 1, and is used to control the movement of the clamping module 32 in the horizontal direction; the Z-axis control module 312 is connected to the X-axis control module 311, and is used to control the movement of the clamping module 32 in the vertical direction; the rotation control module 313 is connected to the Z-axis control module 312, and is used to control the clamping module 32 to rotate along the axial direction of the clamping module 32.

[0068] During actual installation, the X-axis control module 311 is fixedly connected to the first platform 1, and the X-axis control module 311 is provided with a first slide rail along the horizontal direction; the Z-axis control module 312 is installed on the first slide rail of the X-axis control module 311, and the Z-axis control module 312 is provided with a second slide rail along the vertical direction; the rotation control module 313 is installed on the second slide rail of the Z-axis control module 312, and the lower end of the rotation control module 313 is connected to the clamping claw module 32.

[0069] In some embodiments, the above-mentioned clamping jaw module 32 is optimized, such as Figure 3 , 4 As shown, in this embodiment, the clamping module 32 includes a clamping chuck 321 and a positioning fixture 322. The clamping chuck 321 is connected below the rotation control module 313 and is used to grab the gears; the positioning fixture 322 is connected below the clamping chuck 321 and is used to position and fix gears of different specifications. The positioning fixture 322 and the gears are used in conjunction with each other.

[0070] During actual installation, the jaw chuck 321 is connected to the lower end of the rotation control module 313, and slides up and down on the second slide rail of the Z-axis control module 312 along with the rotation control module 313. At the same time, the rotation control module 313 controls the jaw chuck 321 to rotate axially along the jaw chuck 321; the positioning fixture 322 is connected to the bottom of the jaw chuck 321, and moves with the movement of the jaw chuck 321.

[0071] In some embodiments, the gear transmission device 200 is optimized, such as Figure 5As shown, the gear transmission device 200 in this embodiment includes a first conveyor belt 5, a conveyor tray 6, a first material blocking mechanism 71, a second material blocking mechanism 72, a first clamp 81 and a second clamp 82. The first conveyor belt 5 has an elliptical structure and is used to transmit gears. In this embodiment, the first conveyor belt 5 rotates counterclockwise; a plurality of conveyor trays 6 are connected to the first conveyor belt 5 for carrying gears; the first material blocking mechanism 71 is connected to the first conveyor belt 5 for limiting the movement of the conveyor tray 6; the second material blocking mechanism 72 is connected to the first conveyor belt 5 downstream of the first material blocking mechanism 71 for limiting the movement of the conveyor tray 6; the first clamp 81 is connected to the first conveyor belt 5 downstream of the second material blocking mechanism 72 for clamping the conveyor tray 6; the second clamp 82 is connected to the first conveyor belt 5 downstream of the first clamp 81 for clamping the conveyor tray 6.

[0072] In actual operation, a first sensor is installed on the first material blocking mechanism 71. When the first sensor senses that there is no gear on the conveying tray 6 moving to the first material blocking mechanism 71, the first material blocking mechanism 71 will extend a blocking arm to intercept the empty conveying tray 6; when the first sensor senses that there is a gear on the conveying tray 6, the first material blocking mechanism 71 will retract the blocking arm to release the conveying tray 6.

[0073] The second material blocking mechanism 72 is in a release state by default;

[0074] A second sensor is installed on the first clamping jaw 81. When the second sensor senses that there is a gear on the conveying tray 6 moving to the first clamping jaw 81, the first clamping jaw 81 will clamp the conveying tray 6, and the second blocking mechanism 72 will extend the blocking arm to intercept the conveying tray 6 behind; when the second sensor senses that there is no gear on the conveying tray 6, the first clamping jaw 81 will release the conveying tray 6, and the second blocking mechanism 72 will retract the blocking arm to release the conveying tray 6 behind;

[0075] A third sensor is installed on the second clamp 82. When the third sensor senses that there is no gear on the conveying tray 6 that moves to the second clamp 82, the second clamp 82 will clamp the conveying tray 6; when the third sensor senses that there is a gear on the conveying tray 6, the second clamp 82 will release the conveying tray 6.

[0076] In some embodiments, the gear transmission device 200 is optimized, such as Figure 5As shown, the gear conveying device 200 in this embodiment also includes an air drying system 9, which is connected to the downstream of the second clamping jaw 82 on the first conveyor belt 5. The air drying system 9 includes a protective cover 91 and a hot air blower 92. The protective cover 91 is connected to the downstream of the second clamping jaw 82 on the first conveyor belt 5, and is used to prevent the hot air blower 92 from blowing away moisture on the gears that have completed flaw detection and floating to other parts of the gear conveying device when working; the hot air blower 92 is connected to the first conveyor belt 5 in the protective cover 91, and is used to heat and blow away moisture on the gears that have completed flaw detection.

[0077] In actual operation, when the conveying tray 6 carries the gears that have completed the flaw detection into the protective cover 91, the hot air blower 92 starts and heats and blows the gears that have completed the flaw detection to heat and dry the moisture on the gears, so that the gears can enter the next processing link.

[0078] In some embodiments, the gear transmission device 200 is optimized, such as Figure 5 , 6 As shown, the gear conveying device 200 in this embodiment also includes an interception mechanism 10 connected upstream of the first material blocking mechanism 71 on the first conveyor belt 5. The interception mechanism 10 will release the empty conveying tray 6 and intercept the conveying tray 6 with gears to prevent secondary flaw detection of the gears.

[0079] In fact, the elevation of the interception mechanism 10 is a flat rectangle, and the distance between it and the first conveyor belt 5 is just enough to allow an empty conveyor tray 6 to pass through; when there are gears on the conveyor tray 6, they will be intercepted by the interception mechanism 10, avoiding secondary flaw detection of gears that have already completed flaw detection and wasting production time.

[0080] In some embodiments, the gear transmission device 200 is optimized, such as Figure 5 , 7 As shown, the gear conveying device 200 in this embodiment also includes an anti-error plate 11, which is connected to the upstream of the second material blocking mechanism 72 and the downstream of the first material blocking mechanism 71 on the first conveyor belt 5. The size of the anti-error plate 11 is designed according to the model of the gear to be inspected, and is used to intercept gears of different models in the same batch to prevent misjudgment of inspection.

[0081] In fact, a notch is provided below the facade of the anti-error plate 11, and the shape of the notch matches the model of the gear to be inspected; when the model of the gear carried on the conveying tray 6 is the same as the model of the gear to be inspected, the conveying tray 6 passes through the anti-error plate 11 perfectly; when the model of the gear carried on the conveying tray 6 is different from the model of the gear to be inspected, the conveying tray 6 will be intercepted by the anti-error plate 11, avoiding misjudgment of flaw detection and improving the accuracy of gear flaw detection.

[0082] In some embodiments, the above-mentioned automatic ultrasonic gear flaw detection workstation is optimized, such as Figure 1 , 8 As shown, the automatic ultrasonic gear flaw detection workstation in this embodiment also includes a control console 300 and a receiving device 400. The control console 300 is electrically connected to other devices and integrates a control program that controls the operation of other devices; the receiving device 400 includes a manipulator 401 and a second conveyor belt 402. The manipulator 401 is located between the gear conveying device 200 and the second conveyor belt 402, and is used to transfer the gears on the second conveyor belt 402 to the gear conveying device 200; the second conveyor belt 402 is used to receive gears from the welding feed channel.

[0083] The actual working process is as follows: the second conveyor belt 402 receives the gears from the welding feed channel; the robot 401 transfers the welded gears to the gear conveying device 200; then the gear conveying device 200 transports the gears to the bottom of the gear flaw detection device 100; the gear flaw detection device 100 grabs the gears and starts to perform flaw detection on the gears. Gears that pass the flaw detection will be put back to the gear conveying device 200 for air drying. After the air drying is completed, the gears can be transferred to the next processing flow; gears that fail the flaw detection will be placed in the waste basket 12.

[0084] In fact, a cooling system 403 and a sensor device 404 are installed on the second conveyor belt 402. The cooling system 403 is arranged along the second conveyor belt 402 and is used to cool the gears after welding to improve the accuracy of the ultrasonic flaw detection results; the sensor device 404 is connected to the conveying end of the second conveyor belt 402 and is used to monitor whether there are gears at the conveying end of the second conveyor belt 402 and transmit the signal to the manipulator 401.

[0085] During actual operation, the welded gears are unloaded from the welding feed channel to the second conveyor belt 402, and the conveying surface of the second conveyor belt 402 moves from top to bottom; when the welded gears move on the second conveyor belt 402, the cooling system 403 will cool the gears, and the gears will be transported to the conveying end of the second conveyor belt 402 after cooling; after the sensor device 404 detects the gears, it will transmit a signal to the robot 401, and after receiving the signal, the robot 401 will transfer the gears on the sensor device 404 at the conveying end of the second conveyor belt 402 to the gear conveying device 200.

[0086] Furthermore, an auxiliary cooling device 405 is installed above the second conveyor belt 402 . In the present embodiment, the auxiliary cooling device 405 is configured as a fan for auxiliary cooling of the welded gears and enhancing the cooling effect of the cooling system 403 .

[0087] An automatic ultrasonic gear flaw detection working method is applicable to any of the above-mentioned automatic ultrasonic gear flaw detection workstations, such as Fig. 9As shown, specifically including:

[0088] Receiving gears: The second conveyor belt 402 receives gears from the welding feed channel, and the second conveyor belt 402 drives the gears to the sensing device 404 at the end;

[0089] Transferring gear: After the sensor device 404 detects the gear, it will transmit a signal to the robot 401. After receiving the signal, the robot 401 transfers the gear on the sensor device 404 at the end of the second conveyor belt 402 to the empty conveyor tray 6 at the first material blocking mechanism 71; then the conveyor tray 6 carries the gear to the first clamp 81;

[0090] Gear flaw detection: The first clamp 81 clamps the conveying tray 6, and the clamp module 32 grabs the gear; the motion module 31 drives the clamp module 32 and the gear to move to the flaw detection mechanism 4; the motion module 31 drives the clamp module 32 and the gear to perform rotational flaw detection; for gears that pass the flaw detection, they will be returned to the gear conveying device 200 for air drying, and after the air drying is completed, the gear can be transferred to the next processing flow; for gears that fail the flaw detection, they will be placed in the waste basket 12.
