Description

Technical Field

[0001] The present invention relates to the technical field of ball joint sealing ring production and manufacturing, and in particular to a ball joint sealing ring detection device. Background Art

[0002] A ball joint seal is a component used to provide sealing in ball joints. Ball joints are commonly used in mechanical components that require multi-directional rotation or swinging, such as fixed ball joint bearings. Their construction includes a lower bearing concave plate, a spherical crown lining, an upper bearing slide, a polyester slide, a rubber seal, and a dust cover. The ball joint seal provides a seal, preventing leakage of media and the ingress of impurities such as dust, ensuring the proper operation of the ball joint structure.

[0003] The production of ball-joint seals involves multiple precision steps. First, the appropriate rubber material must be selected based on the joint's structural characteristics, followed by high-performance mixing to ensure uniformity. Subsequently, a precise mold must be designed to accommodate the joint's convex or concave spherical shape, ensuring a tight fit between the seal and the joint. Automated technologies, such as high-temperature injection molding or extrusion, are employed during the molding process to enhance production efficiency and precision.

[0004] By simulating the motion of a ball joint seal in an actual working environment and comparing it with a standard part, the wear resistance of the seal is evaluated. The test aims to identify potential failure modes of the seal during wear, such as cracks, deformation, and material spalling, thereby providing a basis for optimized product design.

[0005] Traditional ball-joint seal wear test devices often have a fixed simulation angle. Adjusting the angle requires disassembling and replacing the entire ball-joint fixture, which is extremely inconvenient. Because traditional test devices can only simulate a single, fixed motion angle and force state, they are unable to simulate the actual working conditions of the ball-joint seal under multi-axis coordinated loading. This leads to a deviation between the test results and the actual use of the ball-joint seal, making it impossible to accurately assess its wear resistance and service life in actual working environments. Therefore, to address the above issues, a ball-joint seal detection device was proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a ball joint sealing ring detection device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A ball joint sealing ring detection device includes a bottom plate frame, a top plate frame, and a transmission mechanism provided on the bottom plate frame. The top plate frame is equipped with multiple detection mechanisms. The detection mechanisms include an adjustment assembly and a test assembly. The test assembly includes a single-ear ball joint positioning plate. The single-ear ball joint positioning plate is equipped with a ball joint sleeve. A ball joint body is nested in the ball joint sleeve. A sealing ring body is mounted on the ball joint sleeve and sleeved on the outside of the ball joint body. The ball joint body can rotate about a vertical axis, and the angle of the ball joint body is adjustable. The rotation of the ball joint body is used to test the performance of the sealing ring body. The adjustment component includes a swing arm, which can move up and down. A connecting plate is slidably provided at the bottom of the swing arm. A rotating plate is connected between the connecting plate and the ball-joint body for mutual rotation. The swing arm and the connecting plate are used to adjust the angle of the ball-joint body.

[0008] The above technical solution further includes: The test assembly also includes a mounting shaft seat, which is installed on the top of the base frame.

[0009] The single-ear ball joint positioning plate is installed on the top of the base frame, the ball sleeve is engaged with the inner side of the single-ear ball joint positioning plate, and the angle of the ball sleeve is adjustable. A groove for installing the sealing ring body is opened on the ball sleeve.

[0010] A top sleeve is provided on the top of the sealing ring body, and the top sleeve is provided on the outside of the ball-jointed body. A gear plate is provided on the top of the sealing ring body, which slides relative to the ball-jointed body. A gear ring is provided on the top of the gear plate. An anti-loss pin for limiting the gear ring is inserted on the ball-jointed body, and a tightening bolt threadedly connected to the ball-jointed body is provided on the top of the gear ring.

[0011] The adjustment assembly also includes a mounting threaded column, the swing arm and the mounting threaded column slide relative to each other, and the mounting threaded column is threadedly connected with a distance adjusting bolt and a fastening bolt, and the distance adjusting bolt and the fastening bolt are respectively located on both sides of the swing arm.

[0012] A slide plate is slidingly provided on the inner side of the swing arm, a connecting shaft is fixedly connected to the slide plate, and an adjusting screw threadedly connected to the swing arm is rotatably connected to the side of the slide plate away from the mounting threaded column, and the connecting shaft is fixedly connected to the connecting plate.

[0013] The connecting plate and the rotating plate are connected to each other through a first pin for common rotation. The top of the ball-jointed body is fixedly connected to a connecting block. The connecting block and the rotating plate are connected to each other through a second pin for common rotation.

[0014] The transmission mechanism includes a reduction motor, which is installed on the top of the top plate frame. A driving sprocket is installed at the output end of the reduction motor. A first driven sprocket and a second driven sprocket are installed at one end of each of the multiple mounting threaded columns close to the driving sprocket.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 - Figure 9 As shown, a ball joint sealing ring detection device proposed by the present invention includes a bottom plate frame 4 and a top plate frame 5 and a transmission mechanism provided on the bottom plate frame 4. A plurality of detection mechanisms are installed on the top plate frame 5. The detection mechanisms include an adjustment component and a test component. The test component includes a single-ear ball joint positioning plate 63. A ball joint sleeve 6202 is installed on the single-ear ball joint positioning plate 63. A ball joint body 65 is nested in the ball joint sleeve 6202. A sealing ring body 64 is installed on the ball joint sleeve 6202 and sleeved on the outside of the ball joint body 65. The ball joint body 65 can rotate around a vertical axis, and the angle of the ball joint body 65 is adjustable. The rotation of the ball joint body 65 is used to test the performance of the sealing ring body 64. The adjustment assembly includes a swing arm 615 that can move up and down. A connecting plate 69 is slidably provided at the bottom of the swing arm 615. A rotating plate 67 is connected between the connecting plate 69 and the ball-jointed body 65 for joint rotation. The swing arm 615 and the connecting plate 69 are used to adjust the angle of the ball-jointed body 65. Furthermore, the sealing ring body 64 to be tested is installed on the ball sleeve 6202 so that it is placed outside the ball sleeve body 65, ensuring that it is firmly installed and positioned correctly, in preparation for subsequent testing; the initial position of the swing arm 615 is adjusted to a suitable height, and the position of the connecting plate 69 inside the swing arm 615 is adjusted so that the entire adjustment assembly is in the initial standby state; Furthermore, when adjusting the tilt angle of the ball-joint body 65, the swing arm 615 is moved up and down. When the swing arm 615 moves up and down, it will drive the connecting plate 69 to move synchronously. Then, by adjusting the horizontal position of the connecting plate 69, since the ball-joint body 65 is nested in the ball-joint sleeve 6202, it has a degree of freedom within the ball-joint sleeve 6202, that is, the end of the ball-joint body 65 will tilt under the action of gravity without any restriction. Therefore, when the connecting plate 69 is adjusted to a suitable height and horizontal position, the ball-joint body 65 and the connecting plate 69 are fixed by a detachable pin. When the position of the ball-joint body 65 needs to be adjusted, the pin is used to disconnect the connection between the ball-joint body 65 and the connecting plate 69, and then the adjustment is made.

[0023] Furthermore, after the angle of the ball-joint body 65 is adjusted to a suitable position, the transmission mechanism is activated to rotate the ball-joint body 65 about the vertical axis. Since the sealing ring body 64 is sleeved on the outside of the ball-joint body 65, when the ball-joint body 65 rotates, the sealing ring body 64 and the ball-joint body 65 will generate relative motion.

[0024] Furthermore, by setting the number of rotations of the ball-jointed body 65, during the rotation of the ball-jointed body 65, the rotating ball-jointed body 65 repeatedly applies force to the sealing ring body 64, so that the performance of the sealing ring body 64 under different angles, different rotation speeds and other conditions can be fully understood.

[0025] The test assembly also includes a mounting shaft seat 61, which is mounted on the top of the base frame 4. A threaded shaft 62 is rotatably connected to the mounting shaft seat 61. A first locking bolt 6200 and a second locking bolt 6201 are threadedly connected to the outer side of the threaded shaft 62. The first locking bolt 6200 and the second locking bolt 6201 are located on both sides of the mounting shaft seat 61. The threaded shaft 62 is fixedly connected to the ball sleeve 6202. The single-ear ball joint positioning plate 63 is installed on the top of the bottom frame 4. The ball sleeve 6202 is engaged with the inner side of the single-ear ball joint positioning plate 63. The angle of the ball sleeve 6202 is adjustable. The ball sleeve 6202 is provided with a groove for mounting the sealing ring body 64. Furthermore, the threaded shaft 62 is rotatably set in the mounting shaft seat 61, and the threaded shaft 62 is fixedly connected to the ball sleeve 6202. Since the ball sleeve 6202 is relatively rotatable on the inner side of the single-ear ball joint positioning plate 63, the angle between the ball sleeve 6202 and the vertical direction can be adjusted by rotating the threaded shaft 62. After the adjustment is completed, the threaded shaft 62 is firmly fixed by tightening the first locking bolt 6200 and the second locking bolt 6201 set on both sides. At this time, the angle of the ball sleeve 6202 is fixed.

[0026] A top sleeve 66 is provided on the top of the sealing ring body 64, and the top sleeve 66 is sleeved on the outside of the ball-jointed body 65. A stop plate 613 is provided on the top of the sealing ring body 64, which slides relative to the ball-jointed body 65. A stop ring 610 is provided on the top of the stop plate 613. An anti-lost pin 612 for limiting the stop ring 610 is inserted on the ball-jointed body 65. A tightening bolt 611 is provided on the top of the stop ring 610, which is threadedly connected to the ball-jointed body 65. Furthermore, the sealing ring body 64 is installed in the groove slotted at the top of the ball sleeve 6202. At the same time, the spherical end of the ball sleeve 65 is engaged with the inside of the ball sleeve 6202. When installing the sealing ring body 64, a top sleeve 66 is placed on the top of the sealing ring body 64, a gear plate 613 is placed on the top of the top sleeve 66, and a gear ring 610 is placed on the top of the gear plate 613. At the same time, an anti-loss pin 612 for limiting the gear ring 610 is inserted into the ball sleeve body 65, and finally, the tightening bolt 611 is tightened at the top thread of the ball sleeve body 65 to prevent the sealing ring body 64 from flying away during the test.

[0027] Furthermore, it is worth noting that the inner diameter of the clamping bolt 611 is much larger than the size of the connecting block 68 , so the clamping bolt 611 can be easily removed from the connecting block 68 .

[0028] The adjustment assembly also includes a mounting threaded column 60, between which the swing arm 615 slides relative to each other. The mounting threaded column 60 is threadedly connected to a distance adjustment bolt 6001 and a fastening bolt 6002. The distance adjustment bolt 6001 and the fastening bolt 6002 are respectively located on both sides of the swing arm 615. A slide plate 617 is slidably provided inside the swing arm 615, and a connecting shaft 616 is fixedly connected to the slide plate 617. The side of the slide plate 617 away from the mounting threaded column 60 is rotatably connected to an adjusting screw 614 threadedly connected to the swing arm 615, and the connecting shaft 616 is fixedly connected to the connecting plate 69; A first pin 618 is connected to the connecting plate 69 and the rotating plate 67 for mutual rotation. A connecting block 68 is fixedly connected to the top of the ball-jointed body 65. A second pin 619 is connected to the connecting block 68 and the rotating plate 67 for mutual rotation. Furthermore, when adjusting the angle of the ball-jointed body 65, the second pin 619 is first removed. At this time, the ball-jointed body 65 is in a free state. However, the bottom spherical body of the ball-jointed body 65 is still in a restricted state. Therefore, the ball-jointed body 65 can swing left and right on the vertical plane around the restricted fulcrum with the center point of the bottom spherical body as the restricted fulcrum. A coordinate system is established with the restricted fulcrum as the coordinate origin, so that the ball-jointed body 65 is located in the first quadrant. Further measurements show that the coordinates of the center axis when the second pin 619 is not removed are (X1, Y1). Based on experimental requirements, the angle between the ball-jointed body 65 and the X-axis in the initial state is set to A1. At this time, tanA1=a=X1 / Y1. When the angle between the ball-jointed body 65 and the vertical axis needs to be reduced, the angle between the ball-jointed body 65 and the X-axis is A2. At this time, the coordinates of the center axis of the second pin 619 are (X2, Y2). At this time, A2 is the exact value, which is the angle that the staff needs to adjust. At this time, tanA2=b=X2 / Y2, and only (X2, Y2) needs to be calculated. Furthermore, because the ball-jointed body 65 can use the center point of the bottom spherical body as the coordinate origin, the length of the ball-jointed body 65 is fixed, namely R. Therefore, during the process of the ball-jointed body 65 rotating around the origin, the coordinate point at the center axis of the second pin 619 satisfies X²+Y²=R². Combining the two equations of tanA²=b=X² / Y², we can calculate that (X², Y²), Y2-Y1=dy at this time. By tightening the distance-adjusting bolt 6001, the distance-adjusting bolt 6001 is adjusted upward to a certain distance dy. Then, the swing arm 615 is moved along the sliding groove provided on the outer side of the mounting threaded column 60 until it contacts the distance-adjusting bolt 6001. At this time, the fastening bolt 6002 is tightened to fix the swing arm 615 with the distance-adjusting bolt 6001 and the fastening bolt 6002. Furthermore, when it is necessary to adjust the angle between the ball hitch body 65 and the vertical axis, the slide 617 is moved toward the mounting threaded column 60 by rotating the adjusting screw 614. At this time, the specified movement X2-X1=dx. Therefore, the relationship between trigonometric functions and the functional relationship between the change in the tangent value of the front and rear angles and dy and dx can be used to obtain the values of dy and dx.

[0029] Furthermore, since the rotating plate 67 is rotatably arranged between the connecting plate 69 and the connecting block 68, when there are slight errors in the values of dy and dx, these errors can be offset by adjusting the angle of the rotating plate 67. Specifically, the rotating plate 67 can be rotated to change its angle so that the end of the rotating plate 67 can be reassembled with the connecting block 68.

[0030] The transmission mechanism includes a reduction motor 1, which is mounted on the top of the top plate frame 5. A driving sprocket 10 is mounted on the output end of the reduction motor 1. A first driven sprocket 12 and a second driven sprocket 13 are mounted on one end of a plurality of mounting threaded columns 60 close to the driving sprocket 10. A first chain 11 is sleeved and connected between the second driven sprocket 13 close to the reduction motor 1 and the driving sprocket 10. A second chain 14 is sleeved and connected between two adjacent first driven sprockets 12, and a third chain 17 is sleeved and connected between two adjacent second driven sprockets 13. The top frame 5 is mounted on the top of the bottom frame 4. A plurality of crankshaft bearing sleeves 15 are mounted on the top of the top frame 5. Bearings 16 are mounted in the crankshaft bearing sleeves 15. The bearings 16 are fixedly connected to the mounting threaded columns 60. A dust cover 2 is mounted on the top of the top frame 5. A counter 3 is mounted on the top of the dust cover 2. Furthermore, when the equipment begins operation, reduction motor 1 is powered on and started. Its function is to convert high-speed, low-torque power input into low-speed, high-torque power output to meet subsequent transmission and operating requirements. The output of reduction motor 1 rotates drive sprocket 10. Drive sprocket 10 serves as the starting point for power transmission, and its rotation transmits power to the subsequent sprocket and chain system.

[0031] Furthermore, the second driven sprocket 13 on the threaded mounting post 60 near the reduction motor 1 is connected to the driving sprocket 10 via a first chain 11. When the driving sprocket 10 rotates, the friction of the first chain 11 drives the second driven sprocket 13 to rotate. This process achieves the initial transfer of power from the reduction motor 1 to the first threaded mounting post 60.

[0032] Furthermore, the first driven sprockets 12 on two adjacent threaded mounting posts 60 are connected by a second chain 14. When the first driven sprocket 12 on one threaded mounting post 60 rotates, the second chain 14 drives the first driven sprocket 12 on the adjacent threaded mounting post 60, causing the adjacent threaded mounting post 60 to also rotate. In this way, power is transmitted sequentially to each threaded mounting post 60 via the second chain 14 and the third chain 17, achieving a linkage between multiple threaded mounting posts 60.

[0033] Furthermore, under the action of the chain drive, multiple mounting threaded columns 60 begin to rotate synchronously. During the rotation process, the mounting threaded column 60 first drives the swing arm 615 to rotate around the axis of the mounting threaded column 60, and then the swing arm 615 rotates to drive the connecting shaft 616 to move in a circle. The connecting shaft 616 drives the connecting block 68 to rotate through the connecting plate 69. Since the spherical end of the ball hitch body 65 is engaged in the ball hitch sleeve 6202, and according to the characteristics of the sphere, the ball hitch body 65 can rotate at this time.

[0034] The dust cover 2 installed on the top of the top frame 5 wraps the transmission mechanism and related components. Its main function is to prevent dust, debris, etc. from entering the transmission system, and avoid these impurities from causing wear or jamming to components such as chains, sprockets, and bearings, thereby ensuring the normal operation of the transmission mechanism and extending the service life of the equipment.

[0035] The counter 3 mounted on top of the dust cover 2 can be used to record relevant data such as the number of rotations of the mounting threaded stud 60. By recording the number of rotations, the operating status and operating time of the equipment can be easily understood. The number of rotations can also be used to determine the performance changes of the sealing ring after a specific number of rotations.

[0036] In this embodiment, the sealing ring body 64 to be tested is first installed into the groove of the ball sleeve 6202 and secured with a top sleeve 66, a stop plate 613, a stop ring 610, and a clamping bolt 611. A locking pin 612 prevents the components from falling out. The angle of the ball sleeve 6202 is adjusted by rotating the threaded shaft 62 and locked with the first and second locking bolts 6200 and 6201. A reduction motor 1 drives the driving sprocket 10 to rotate, which, through the first, second, and third chains 11, 14, and 17, drives the multiple threaded mounting posts 60 to rotate synchronously. The threaded mounting posts 60 drive the swing arm 615 to rotate. The swing arm 615, via the connecting shaft 616, connecting plate 69, and rotating plate 67, drives the ball sleeve body 65 to rotate within the ball sleeve 6202, simulating the working state of the sealing ring body 64. The position of the connecting plate 69 is adjusted by adjusting the screw 614. Combined with the distance adjustment bolt 6001 and the tightening bolt 6002, the angle of the ball sleeve body 65 can be varied, enabling multi-angle testing. The dust cover 2 prevents dust from entering, and the counter 3 records the number of rotations to evaluate the performance of the sealing ring.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the appended claims and their equivalents.
