Description

Technical Field

[0001] The present invention relates to flaw detection equipment, and more particularly to a flaw detection equipment for a cylindrical shell of a high-speed transmission shaft moving section. Background Art

[0002] In modern automotive drivetrains, high-speed driveshaft moving joints (ball-and-cage universal joints) play a crucial role. They allow the driveshaft to flexibly adjust its angle during vehicle operation, responding to changes in the steering and suspension systems, thereby ensuring smooth power transmission. During production, the moving joint's cylindrical housing (i.e., the outer planetary wheel of the ball-and-cage universal joint) undergoes multiple processing steps, including casting, heat treatment, and machining. These processes can cause defects such as cracks, wear, and rust on the inner and outer surfaces of the housing. Therefore, rigorous post-production inspection of the housing for internal and external flaws is crucial for ensuring product quality and reliability. This inspection utilizes electromagnetic flaw detection devices (which use the principle of electromagnetic induction to detect internal defects by emitting electromagnetic waves and receiving their reflected signals) and ultrasonic flaw detection devices (which exploit the propagation characteristics of ultrasonic waves within an object by emitting ultrasonic waves and receiving their reflected or transmitted signals).

[0003] The cylindrical shell of the existing movable joint is often covered with dirt and impurities on the inner and outer surfaces after production. However, the presence of dirt may bring a variety of adverse effects during the flaw detection process. For example, the flaw detector's sensor cannot accurately receive the reflected or transmitted signals from the product under the influence of dirt. Some dirt may absorb ultrasonic waves, causing the ultrasonic waves to be unable to penetrate the interior of the outer star wheel. In addition, dirt may also cover up tiny defects on the surface of the outer star wheel, thereby affecting the flaw detection results. At present, some flaw detection lines are combined with cleaning lines to solve the problem of dirt influence. However, it is still difficult to achieve a comprehensive and effective cleaning effect for the specific product of the cylindrical shell of the drive shaft movable joint, which affects the flaw detection results. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an internal and external flaw detection device for the cylindrical shell of a moving section of a high-speed transmission shaft, so as to solve the problem in the above-mentioned background technology that when flaw detection is performed on the cylindrical outer shell of the moving section, the surface dirt affects the detection results of the flaw detection equipment, resulting in insufficient detection accuracy of the cylindrical shell of the moving section by the existing flaw detection equipment.

DETAILED DESCRIPTION

[0033] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1-4 The present invention provides an internal and external flaw detection device for a cylindrical shell of a high-speed transmission shaft moving section, comprising a conveyor belt 1, a flaw detection mechanism 2 provided on the conveyor belt 1, a box shell 3 provided on the conveyor belt 1, a cleaning mechanism 4 provided inside the box shell 3, and a manipulator assembly 5 installed inside the box shell 3 at the top of the conveyor belt 1;

[0035] The cleaning mechanism 4 includes a plate 41, a hole is opened on the top of the plate 41, and a hollow platform 42 is fixedly connected to the inner wall of the hole, and a liquid collecting shell 44 is fixedly connected to the bottom of the hollow platform 42. A top cover shell 43 is provided on the top of the hollow platform 42, and a self-spinning inner nozzle 47 is provided inside the liquid collecting shell 44. An annular self-spinning nozzle 48 is provided inside the top cover shell 43. The side walls of the top cover shell 43 and the liquid collecting shell 44 are both installed with a gas-liquid supply mechanism 46 and a lifting assembly 49. The output ends of the two lifting assemblies 49 are respectively connected to the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48. The output ends of the two gas-liquid supply mechanisms 46 are respectively connected to the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48. A lifting arm assembly 45 is installed on the top of the plate 41, and the output end of the lifting arm assembly 45 is connected to the top of the top cover shell 43;

[0036] The two lifting assemblies 49 cooperate with the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48 to control the gas-liquid output switching of the two gas-liquid supply mechanisms 46.

[0037] The cylindrical shell of the product to be inspected is transported by the conveyor belt 1. First, the product enters the box shell 3 and is grabbed by the robot assembly 5 and sent to the cleaning mechanism 4 for cleaning. After cleaning, the product is grabbed by the robot assembly 5 and sent to the conveyor belt 1 and input into the flaw detection mechanism 2 for testing, thereby preventing impurities on the product surface from affecting the flaw detection.

[0038] During cleaning, the cylindrical shell is placed on top of the hollow stand 42, and the inner and outer surfaces of the cylindrical shell are cleaned simultaneously by the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48. During the cleaning process, the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48 rotate, and cooperate with the two lifting components 49 to control the lifting of the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48, so that the cleaning mechanism 4 can achieve a full-range cleaning effect for the inside and outside of the cylindrical shell, avoiding the existence of blind spots in cleaning. During the cleaning process, the cylindrical shell is cleaned in a closed state under the action of the top cover shell 43 and the liquid collecting shell 44 to prevent liquid leakage;

[0039] In addition, the two gas-liquid supply mechanisms 46 can enable the spinning inner nozzle 47 and the annular spinning nozzle 48 to switch between liquid spraying and air jetting, so that the cylindrical shell can achieve all-round cleaning while also achieving an all-round air drying effect, avoiding the influence of liquid adhering to the surface of the product after cleaning on subsequent inspections, and the air jet effect can also help blow out impurities and dirt in the gaps on the surface of the cylindrical shell, thereby enhancing the dirt treatment effect.

[0040] Reference Figure 4 A thimble 411 is fixedly connected to the top of the inner wall of the top cover shell 43, and the thimble 411 cooperates with the hollow stand 42 to clamp the cleaning workpiece.

[0041] When the cylindrical shell is cleaned by the self-spinning inner nozzle 47 and the annular self-spinning nozzle 48, the cylindrical shell is easily deflected by the impact force. The cylindrical shell is clamped by the ejector pin 411 in conjunction with the hollow stand 42 to improve stability.

[0042] Reference Figure 5 The annular self-spinning nozzle 48 includes an annular box 481, the inner wall of the annular box 481 is provided with an annular groove connected to the interior, a rotating wall 482 is rotatably sleeved in the annular groove, and a plurality of oblique nozzles 483 are provided on the side wall of the rotating wall 482, and the oblique nozzles 483 have an angle greater than 90° with the inner wall of the rotating wall 482.

[0043] When the gas and liquid are output through the gas-liquid supply mechanism 46, they enter the interior of the annular box 481 and are ejected through the oblique nozzle 483. Since the angle between the oblique nozzle 483 and the inner wall of the rotating wall 482 is greater than 90°, that is, the injection direction of the oblique nozzle 483 deviates from the center line of the rotating wall 482, the oblique nozzle 483 has a rotational driving force on the rotating wall 482 when spraying, thereby achieving the spinning effect of the annular spinning nozzle 48.

[0044] Reference Figure 6 The self-spinning internal nozzle 47 includes a connecting frame 471, a vertical pipe 472 is fixedly installed on the top of the connecting frame 471, a screw cap head 473 is rotatably sleeved on the top of the vertical pipe 472, and a plurality of oblique nozzles 474 are provided on the side wall of the screw cap head 473. The angle between the oblique nozzles 474 and the side wall of the screw cap head 473 is greater than 90 degrees. A top nozzle 475 is provided on the top of the screw cap head 473;

[0045] The lifting and lowering arm assembly 45 includes a vertical plate 451, an electric cylinder 452 is fixedly installed on the front of the vertical plate 451, the output end of the electric cylinder 452 is fixedly connected to the connecting arm 454, a telescopic rod 453 is installed on the back of the vertical plate 451, the output end of the telescopic rod 453 is fixedly connected to the bottom of the connecting arm 454, the bottom of the connecting arm 454 is fixedly connected to the connecting rod 455, and the bottom end of the connecting rod 455 is fixedly connected to the top of the top cover shell 43.

[0046] The gas and liquid outputted by the gas-liquid supply mechanism 46 enter the interior of the vertical pipe 472, and then enter the interior of the screw cap head 473 through the vertical pipe 472. Since the angle between the second oblique nozzle 474 and the side wall of the screw cap head 473 is greater than 90 degrees, that is, it is in an inclined state, the reverse driving force generated by the spraying of the second oblique nozzle 474 drives the screw cap head 473 to rotate, thereby achieving the self-spinning effect of the self-spinning inner nozzle 47;

[0047] The connecting arm 454 is driven to move up and down by outputting power through the electric cylinder 452. Under the connection effect of the connecting rod 455, the lifting arm assembly 45 controls the lifting of the top cover shell 43. By setting the telescopic rod 453, the stability of the connecting arm 454 during lifting can be improved.

[0048] Reference Figure 4 The lifting assembly 49 includes an electric cylinder 491, the output end of the electric cylinder 491 is connected to a transmission rod 493 through a connecting block 492, and the transmission rods 493 of the two lifting assemblies 49 respectively pass through the top cover shell 43, the top and bottom of the liquid collecting shell 44, and are connected to the annular spinning nozzle 48 and the spinning inner nozzle 47.

[0049] The power outputted by the second electric cylinder 491 is used to control the lifting of the transmission rod 493 under the connection of the connecting block 492, and the annular self-spinning nozzle 48 and the self-spinning inner nozzle 47 are driven to lift and lower through the transmission rod 493.

[0050] Reference Figure 8The gas-liquid supply mechanism 46 includes a liquid-connected telescopic cylinder valve 460 and an air-connected telescopic cylinder valve 461. The output ends of the liquid-connected telescopic cylinder valve 460 and the air-connected telescopic cylinder valve 461 of the two gas-liquid supply mechanisms 46 are respectively connected to the annular spin nozzle 48 and the annular spin nozzle 48. The top of the liquid-connected telescopic cylinder valve 460 is connected to the high-pressure liquid supply mechanism through a liquid hose 462, and the top of the air-connected telescopic cylinder valve 461 is connected to the high-pressure air supply mechanism through an air hose 463. The liquid-connected telescopic cylinder valve 460 and the air-connected telescopic cylinder valve 461 have the same structure. When the liquid-connected telescopic cylinder valve 460 is extended to the maximum length, the valve is closed, and when it is retracted to the shortest length, the valve is open. The valve state of the air-connected telescopic cylinder valve 461 is opposite to that of the liquid-connected telescopic cylinder valve 460.

[0051] Since the lifting component 49 drives the annular spinning nozzle 48 to rise and fall, the liquid-connected telescopic tube valve 460 and the gas-connected telescopic tube valve 461 are driven to extend and retract when the annular spinning nozzle 48 rises and falls. In the initial state, the liquid-connected telescopic tube valve 460 and the gas-connected telescopic tube valve 461 are at the shortest length. At this time, the valve of the liquid-connected telescopic tube valve 460 is open and the valve of the gas-connected telescopic tube valve 461 is closed, that is, the gas-liquid supply mechanism 46 outputs liquid to clean the cylindrical shell with water. After the lifting component 49 is running, the liquid-connected telescopic tube valve 460 and the gas-connected telescopic tube valve 461 gradually extend until they reach the maximum length, and then the valve states of the liquid-connected telescopic tube valve 460 and the gas-connected telescopic tube valve 461 are switched, that is, the gas-liquid supply mechanism 46 outputs gas to blow and dry the cylindrical shell.

[0052] Reference Figure 4 The self-spinning inner nozzle 47 is connected to the liquid-connected telescopic cylinder valve 460 and the gas-connected telescopic cylinder valve 461 of the gas-liquid supply mechanism 46 through the three-way pipe 410.

[0053] Since the gas-liquid supply mechanism 46 has two output ends, the liquid-connected telescopic cylinder valve 460 , the gas-connected telescopic cylinder valve 461 and the vertical pipe 472 of the self-spinning inner nozzle 47 can be connected by setting a three-way pipe 410 .

[0054] Reference Figure 9 The liquid-connected telescopic cylinder valve 460 includes an outer cylinder 464, and the top and bottom of the gas-connected telescopic cylinder valve 461 are provided with through holes. The inner moving cylinder 466 is slidably sleeved in the through hole at the bottom of the outer cylinder 464, and a rotary valve 465 is installed in the through hole at the top of the outer cylinder 464. A rotating frame 467 docking with the rotary valve 465 is provided inside the outer cylinder 464, and a linkage touch plate 468 for triggering the rotation and reset of the rotating frame 467 is installed on the top of the side wall of the inner moving cylinder 466. The bottom end of the rotary valve 465 is fixedly connected to the telescopic bellows 469, and the bottom end of the telescopic bellows 469 is rotatably sleeved on the top of the inner cavity of the rotating frame 467.

[0055] When the liquid-connected telescopic cylinder valve 460 is extended, the inner moving cylinder 466 slides down, driving the linkage touch plate 468 to move downward until the linkage touch plate 468 contacts the lower part of the rotating frame 467 to rotate the rotating frame 467. The rotation of the rotating frame 467 switches the linkage touch plate 468. After the liquid-connected telescopic cylinder valve 460 retracts, the linkage touch plate 468 contacts the upper part of the rotating frame 467 to drive the rotating frame 467 to reset. At this time, the rotation of the rotating frame 467 restores the rotary valve 465 to its initial state, thereby achieving the effect of telescoping and switching the valve state of the liquid-connected telescopic cylinder valve 460, and the sealing performance is ensured by providing the telescopic bellows 469.

[0056] Reference Figure 9 The rotating frame 467 includes a top rotating cylinder 4671 and a bottom rotating cylinder 4672. The top rotating cylinder 4671 and the bottom rotating cylinder 4672 are fixedly connected by a number of middle rods 4673. The bottom end of the top rotating cylinder 4671 is provided with a slope groove 1, and the top end of the bottom rotating cylinder 4672 is provided with a slope groove 2 in the opposite direction of the slope groove 1. The linkage touch plate 468 includes an end plate 4681. The top and bottom of the end plate 4681 are fixedly connected with a resistance protrusion 4682. The end plate 4681 is fixedly connected to the top of the side wall of the inner moving cylinder 466.

[0057] When the linkage touch plate 468 contacts the lower part of the rotating frame 467, that is, the interference protrusion 4682 at the bottom of the end plate 4681 contacts the slope of the slope groove 2 at the top of the bottom rotating cylinder 4672, the interference protrusion 4682 slides along the slope under the influence of pressure, causing the bottom rotating cylinder 4672 to rotate, and the rotating frame 467 can rotate as a whole under the connection effect of the middle rod 4673. Conversely, when the linkage touch plate 468 contacts the upper part of the top rotating cylinder 4671, the interference protrusion 4682 at the top of the end plate 4681 causes the top rotating cylinder 4671 to flip over, and the rotating frame 467 can be flipped and reset as a whole.

[0058] Reference Figure 10 The rotary valve 465 includes a fixed valve plate 4651 , a movable valve plate 4652 is attached to the bottom of the fixed valve plate 4651 , and a plurality of through holes are provided at eccentric positions on the tops of the fixed valve plate 4651 and the movable valve plate 4652 .

[0059] When the rotary valve 465 is triggered, the movable valve plate 4652 rotates while the fixed valve plate 4651 remains in position. At this time, several perforations on the fixed valve plate 4651 and the movable valve plate 4652 are misaligned, and the movable valve plate 4652 seals the perforations of the fixed valve plate 4651, switching the rotary valve 465 from an open state to a closed state.
