Description

Technical Field

[0001] The present invention relates to the technical field of automotive half - shaft detection, and particularly to a flaw detection device for automotive half - shafts. Background Art

[0002] The automotive half - shaft is an important transmission component connecting the differential and the wheels. During vehicle operation, it bears huge torque and alternating stress. The main purpose of the half - shaft flaw detection equipment is to comprehensively inspect the half - shaft during the production process or vehicle maintenance and repair, timely detect potential defects, ensure the quality and safety of the half - shaft, and avoid vehicle driving instability, transmission failure or even safety accidents caused by half - shaft failures.

[0003] After the production of the half - shaft is completed, it is necessary to detect the material inhomogeneity of the half - shaft, which is mainly used to detect defects on the surface and near - surface of ferromagnetic materials. When the material has inhomogeneity, it may cause changes in the local magnetic field. However, such changes are generally weak and relatively dispersed. If the magnetic powder or magnetic suspension fluid aggregates to form clear, continuous and directional lines or patterns, it may be a magnetic leakage phenomenon caused by defects on the half - shaft surface.

[0004] When the existing flaw detection equipment is in use, generally, the half - shaft is magnetized by passing an electric current first, and then magnetic powder is applied to the surface of the half - shaft or the half - shaft is immersed in the magnetic suspension fluid. However, when the half - shaft is immersed in the magnetic suspension fluid, due to the complex shape of some half - shafts, local accumulation may occur at some positions on the half - shaft surface, resulting in inaccurate detection. Therefore, a flaw detection device for automotive half - shafts is proposed. Summary of the Invention

The swing plate is rotationally connected to the soaking bin through a pin shaft. A plurality of through holes are arranged on the surface of the swing plate. Two groups of swing plates are symmetrically arranged inside the soaking bin with respect to the axis of the transmission rod.

[0009] Preferably, a number of stirring plates are also fixedly connected to the surface of the transmission rod. Two groups of matching blocks are arranged on the left and right of the transmission rod. The concave and convex parts of the two groups of matching blocks are arranged in a spatial staggered manner. When moving, the two wiping plates move alternately up and down. A second sliding column is in sliding contact above the matching block. The upper part of the second sliding column is detachably connected to a driving plate. A wiping plate is fixedly connected above the driving plate. A brush is arranged on the inner side surface of the wiping plate.

[0010] Preferably, the second sliding column is in sliding connection with the soaking bin, and a return spring is arranged at the sliding position. A spring strip is also arranged between the two driving plates. Through holes are formed on the surfaces of the driving plate and the wiping plate.

The air spraying ports are also arranged at a certain angle. The hair dryer is detachably connected to the soaking bin.

[0012] Preferably, the liquid suction pipe below the circulating machine penetrates through the inside of the soaking bin. The ring cylinder is arranged around the outside of the soaking bin. The circulating machine is arranged outside the ring cylinder. The screw rod is rotationally connected to the housing. The two wiping cylinders are arranged on the front and back sides of the screw rod.

[0013] Preferably, both the soaking chamber and the annular cylinder are made of materials with high corrosion resistance and high strength. The multiple liquid absorption plates arranged on the surface of the wiping cylinder are detachably connected thereto. Two sets of the circulating machine and the filter are arranged on the front and rear sides of the soaking chamber, and the two active plates are arranged in a staggered manner up and down.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the first motor rotates to drive the rotating shaft to rotate. While the rotating shaft rotates, it drives two driving wheels to rotate. The driving wheels drive the driven wheels to rotate through meshing transmission. The rotation of the driven wheels can drive the screw rod to rotate. The rotation of the screw rod drives the slide plate to move downward inside the support rod through screw transmission until it moves into the magnetic suspension liquid placed inside the soaking chamber. At this time, the electric motor is started to drive the mounting sleeve and the half shaft part to rotate, so that the magnetic suspension liquid can be fully and evenly laid on the surface of the half shaft part. At this time, the half shaft part is magnetized, which is convenient for the staff to observe the surface and near surface of the half shaft part and facilitate the judgment of the defects existing on the surface of the half shaft part.

[0016] 2. In the present invention, the second motor rotates to drive the transmission rod to rotate. The transmission rod drives two staggered matching blocks to rotate. The rotation of one of the matching blocks can push the sliding block to move back and forth. The movement of the sliding block can push the first sliding rod to move up and down reciprocally. The first sliding rod will drive the swing plate to swing around the pin shaft through the hinge ball. The swing of the swing plate can make the magnetic suspension liquid inside the soaking chamber slap on the surface of the half shaft part, which can assist in cleaning the impurities on the surface of the half shaft part. At the same time, the rotation of the matching block can drive the second sliding column to move up and down reciprocally. The movement of the second sliding column can drive the wiping plates above the two active plates to move up and down alternately. The two wiping plates can drive the brush to wipe the surface of the rotating half shaft part, so as to achieve a better effect of cleaning impurities such as oil stains on its surface and avoid the phenomenon of inaccurate subsequent detection.

[0017] 3. In the present invention, the driving wheels drive the driven wheels to reverse through meshing transmission. At this time, the screw rod reverses to drive the slide plate to move upward. The movement of the slide plate can drive the half shaft part to move upward. Since there are two belt wheels and belts arranged on the surface of the rotating shaft, when the half shaft part moves to the liquid absorption plates arranged on the surfaces of the two wiping cylinders, the rotation of the wiping cylinders at this time can drive the liquid absorption plates to adsorb the residual moisture on the surface of the half shaft part, preventing excessive residual magnetic suspension liquid from damaging the half shaft part body. At the same time, the hair dryer is started to generate wind and spray it on the surface of the half shaft part through the air outlet, which can improve the cleaning efficiency of the residual liquid on its surface and has good protection.

Two groups of matching blocks 20 are arranged on the left and right of the surface of the transmission rod 19, and the concave and convex parts of the two groups of matching blocks 20 are arranged in a spatial staggered manner. When moving, the two wiping plates 28 move up and down alternately. A second sliding column 26 is in sliding contact with the upper part of the matching block 20. An active plate 27 is detachably connected above the second sliding column 26. A wiping plate 28 is fixedly connected above the active plate 27, and a brush is arranged on the inner side of the wiping plate 28.

[0032] Further, in order to facilitate the recycling of the magnetic suspension liquid and filter the impurities remaining after cleaning the oil stains on the surface of the half shaft member 17, improve the utilization rate of the magnetic suspension liquid and reduce the use cost, the second sliding column 26 is slidably connected to the soaking chamber 3, and a return spring is arranged at the sliding position. A spring strip is also arranged between the two active plates 27. Through holes are formed on the surfaces of the active plate 27 and the wiping plate 28. A circulating machine 4 is arranged outside the soaking chamber 3. A liquid suction pipe is fixedly connected below the circulating machine 4, and a filter 5 is connected to the inside of the liquid suction pipe. The filter 5 is detachably connected to the soaking chamber 3. A ring cylinder 6 is fixedly connected to one side of the circulating machine 4. A number of liquid spraying ports are arranged on one side of the ring cylinder 6, and the liquid spraying ports are fixedly connected to the soaking chamber 3 and are arranged at a certain angle.

[0033] Further, in order to further clean the magnetic suspension liquid remaining on the surface of the half shaft member 17, a hair dryer 24 is arranged above the soaking chamber 3. A number of air spraying ports are arranged on the side of the hair dryer 24 close to the half shaft member 17, and the air spraying ports are also arranged at a certain angle. The hair dryer 24 is detachably connected to the soaking chamber 3.

[0034] Further, in order to facilitate the half shaft member 17 to be gently and stably immersed in the magnetic suspension liquid and evenly cover the surface of the half shaft member 17, the liquid suction pipe below the circulating machine 4 penetrates through the inside of the soaking chamber 3. The ring cylinder 6 is arranged around the outside of the soaking chamber 3, and the circulating machine 4 is arranged outside the ring cylinder 6. The screw rod 11 is rotatably connected to the housing 1. Two groups of wiping cylinders 14 are arranged on the front and back sides of the screw rod 11.

[0035] Furthermore, in order to facilitate improving the service life of local parts in the device, both the soaking chamber 3 and the ring cylinder 6 are made of materials with high corrosion resistance and high strength. A number of liquid absorbing plates arranged on the surface of the wiping cylinder 14 are detachably connected to it. Two groups of the circulating machine 4 and the filter 5 are arranged on the front and back sides of the soaking chamber 3. The two active plates 27 are arranged in a vertical staggered manner.

[0036] Working principle: After the present invention is installed, first, an appropriate amount of magnetic suspension liquid is added into the soaking chamber 3, and then the half shaft part 17 to be inspected is installed into the two mounting sleeves 16. When it is necessary to inspect the installed half shaft part 17, at this time, start the first motor 7 to rotate, driving the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 can drive the driving wheel 9 and the driven wheel 10 to engage and rotate. The driving wheel 9 drives the driven wheel 10 to rotate through meshing transmission. The rotation of the driven wheel 10 can drive the screw 11 to rotate. The screw 11 rotates and drives the slide plate 25 to move between the two support rods 2 towards the position close to the soaking chamber 3 until the half shaft part 17 moves to the middle position between the two wiping plates 28, completing the preparation work;

[0037] After the preparation work is completed, at this time, start the electric motor 15 to drive the mounting sleeve 16 to rotate. The rotation of the mounting sleeve 16 can drive the half shaft part 17 to rotate inside the two wiping plates 28. Since a brush is provided on the surface of the wiping plate 28 close to the half shaft part 17, the rotation of the half shaft part 17 can contact the brush at this time, and can wipe and clean the oil stains and other impurities on its surface. At the same time, start the second motor 18 to rotate, driving the transmission rod 19 and the matching block 20 on its surface to rotate. When the matching block 20 rotates, it can push the sliding block 21 to move. The sliding block 21 can push the first sliding rod 22 to move up and down reciprocally through the convex block. When the first sliding rod 22 moves, it will drive the swing plate 23 to swing around the pin shaft through the hinge ball. At this time, the swing of the swing plate 23 can swing the magnetic suspension liquid inside the soaking chamber 3 to both sides of the wiping plate 28, and slap it from the through holes on both sides of the wiping plate 28 onto the surface of the half shaft part 17, which can improve the cleaning efficiency of the oil stains and other impurities on the surface of the half shaft part 17, and the cleaning quality is high;

[0038] When the matching block 20 rotates, it can also push the second sliding column 26 to rotate. Since the concave and convex parts of the two matching blocks 20 are arranged in a spatial staggered manner, the movement of the two matching blocks 20 can push the active plate 27 above the second sliding column 26 to move up and down reciprocally. At this time, the movement of the active plate 27 can drive the two wiping plates 28 and the brushes on their sides to move. At this time, through the self-rotation of the half shaft part 17 and the up and down reciprocating movement of the wiping plates 28, the impurities on the surface of the half shaft part 17 can be better cleaned;

[0039] When the half shaft part 17 is immersed in the soaking chamber 3, at this time, start the circulating machine 4 to circulate and use the magnetic suspension liquid inside the soaking chamber 3. The filter 5 provided below the circulating machine 4 can filter and clean the impurities generated when cleaning the surface of the half shaft part 17, which can effectively prevent the impurities from affecting the magnetization of the subsequent half shaft part 17, and can effectively improve the quality of the surface and near-surface inspection of the half shaft part 17;

[0040] After the impurities such as oil stains on the surface of the half shaft part 17 are cleaned, the electric motor 15 and the second motor 18 are turned off at this time, and the half shaft part 17 stops rotating. Then, the mounting sleeve 16 is electrified to magnetize the half shaft part 17, which is convenient for the staff to observe the surface and near-surface of the half shaft part 17 to judge what damages the half shaft part 17 has. After the detection is completed, the first motor 7 is started to reverse to make the half shaft part 17 move upward. When the half shaft part 17 moves to the middle position between the two wiping cylinders 14, since the rotation of the rotating shaft 8 can drive the belt pulley 12 to rotate, the belt pulley 12 drives the wiping cylinder 14 to rotate through the belt 13. The rotation of the two wiping cylinders 14 can drive the liquid suction plate to rotate, and the rotation of the liquid suction plate can adsorb the liquid remaining on the surface of the half shaft part 17 to prevent the liquid remaining on the surface of the half shaft part 17 from causing damage to it. At the same time, the blower 24 is started to move to generate wind to blow on the surface of the half shaft part 17, which can better clean the liquid remaining on the surface of the half shaft part 17.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the spirit and principle of the present invention. The scope of the present invention is defined by the claims and their equivalents.
