Description

Technical Field

[0001] The present invention relates to the technical field of drive shaft detection, and in particular to a drive shaft assembly stability detection device. Background Art

[0002] The drive shaft assembly is an important component in the automobile transmission system. Its main function is to transmit the power generated by the engine to the drive wheels so that the car can move. The drive shaft assembly is usually installed between the differential or the final reduction gear and the wheel hub. It is assembled from universal joints, intermediate shafts, dust covers and other parts. Since the quality of the drive shaft assembly is related to the safety of the car, the drive shaft assembly needs to undergo a series of tests and inspections after assembly to ensure the quality of the drive shaft assembly, including stability testing of the drive shaft assembly.

[0003] Existing equipment generally fixes the drive shaft assembly and drives it through a driving device to detect whether the drive shaft assembly is stable during rotation. For example, the related technology (CN220084335U) discloses a drive shaft assembly vibration detection device, including a base, a drive mechanism and a load mechanism. The drive mechanism includes a drive motor and a drive box, and the drive box is provided with a drive spindle. The load mechanism includes a load motor and a load box, and the load box is provided with a load spindle; it also includes a drive connection component for connecting the movable end of the drive shaft assembly with the drive spindle, and a load connection component for connecting the fixed end of the drive shaft assembly with the load spindle. The drive connection component is equipped with a vibration detection component for detecting the vibration of the drive shaft assembly. The working conditions on the vehicle are simulated by the drive mechanism and the load mechanism, which solves the problem of off-vehicle detection of the vibration performance of the drive shaft assembly during the manufacturing stage or the later maintenance stage, improves the vibration performance detection accuracy of the drive shaft assembly, and avoids the drive shaft assembly with excessive vibration performance from being installed on the whole vehicle.

[0004] However, the existing inspection equipment cannot realize automatic loading and unloading. When performing stability inspection on the drive shaft assembly, manual assistance is required for deployment and placement, which is not suitable for large-scale drive shaft assembly inspection. Therefore, it is necessary to propose a drive shaft assembly implementation equipment that can realize automatic loading and unloading and inspection operations. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a drive shaft assembly stability detection device.

[0006] The present invention is implemented by the following technical scheme: a base frame, the base frame is provided with a guide groove for guiding the drive shaft assembly and a rotatable rotating wheel for transferring the drive shaft assembly, the rotating wheel is provided with a plurality of shaft frames for limiting the drive shaft assembly and capable of lifting and resetting, the rotating wheel is provided with a movable driving mechanism, and the driving mechanism is provided with a vibration detection mechanism; The driving mechanism includes two moving frames, each of which is provided with a sleeve frame, each of which is rotatably provided with a transmission cylinder matching the spline end of the drive shaft assembly, and the corresponding sleeve frame is provided with a third motor for driving the transmission cylinder to rotate, and a triangular stop block that can squeeze the shaft frame to descend is provided on the side where the two moving frames are close to each other.

[0007] As a further improvement of the above scheme, a bidirectional screw is rotatably installed on the rotating wheel, and a second motor for driving the bidirectional screw to rotate is arranged on the base frame. The two ends of the bidirectional screw respectively pass through the two moving frames and are threadedly connected with the two moving frames, thereby driving the two moving frames to move closer to or away from each other.

[0008] As a further improvement of the above solution, two pairs of sliding rods are arranged on the base frame, and the two pairs of sliding rods respectively penetrate the corresponding moving frames and are slidably connected thereto, thereby ensuring that the two moving frames can move smoothly and stably driven by the bidirectional screw rod.

[0009] As a further improvement of the above scheme, multiple pairs of T-shaped rods are arranged on the rotating wheel, and the multiple pairs of T-shaped rods respectively penetrate the corresponding shaft frames and are slidably connected thereto. The multiple pairs of T-shaped rods are all sleeved with a first spring, and the two ends of the first spring are respectively against the rotating wheel and the shaft frame.

[0010] As a further improvement of the above scheme, the sleeve frame is telescopically and slidably connected to the mobile frame, and a turntable connected to the third motor is rotatably installed on the corresponding mobile frame. A pull rod is rotatably installed on the turntable, and one end of the pull rod is hinged to the corresponding sleeve frame, so that the drive shaft assembly can adjust the angle by lifting one end when rotating, so that the stability detection is more comprehensive.

[0011] As a further improvement of the above scheme, a retractable driving rod is rotatably arranged on the corresponding movable frame, and the driving rod consists of a sleeve and a telescopic rod. The sleeve of the driving rod is connected to the output shaft of the third motor and is transmitted to the turntable through a bevel gear. The telescopic rod of the driving rod is rotatably connected to the corresponding sleeve and is transmitted to the corresponding transmission cylinder through a bevel gear, so that the third motor can not only drive the driving shaft assembly to rotate, but also realize the angle change when the driving shaft assembly rotates.

[0012] As a further improvement of the above scheme, the vibration detection mechanism includes a sleeve, in which a push rod, a vibration sensor and a second spring are slidably installed. The second spring is slidably sleeved outside the vibration sensor and its two ends are respectively abutted against the top of the push rod and the top inner wall of the sleeve. The push rod contacts the rotating drive shaft, so as to determine the stability of the drive shaft assembly by detecting the vibration amplitude of the drive shaft assembly when it rotates.

[0013] As a further improvement of the above solution, the tops of the two sleeves are hinged with a same telescopic frame, and the sleeve passes through the telescopic frame and is fixedly connected to the telescopic frame, so that the vibration detection mechanism can adapt to the lifting and lowering of the transmission cylinder and the angle change of the drive shaft assembly.

[0014] As a further improvement of the above scheme, a spherical roller is provided at the bottom of the push rod, which not only prevents the push rod from wearing the rotating drive shaft assembly, but also the spherical shape of the roller enables it to better adapt to the angle change when the drive shaft assembly rotates.

[0015] As a further improvement of the above solution, a first motor is arranged on the base frame, and circular gears are arranged on the output shaft of the first motor and the shaft rod of the rotating wheel, and the two circular gears are meshed with each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting a rotating wheel and a material guide trough, and setting a driving mechanism on the rotating wheel, a new drive shaft assembly stability detection device is formed. Compared with the traditional drive shaft assembly stability detection device, the drive shaft assembly can be automatically deployed and unloaded, making the stability detection of the drive shaft assembly more automated, eliminating the tedious manual deployment, and more suitable for large-scale drive shaft assembly stability detection; By arranging a shaft frame that can be lifted and reset on the rotating wheel, and arranging a triangular stop block that can press the shaft frame on the driving mechanism, the driving mechanism can separate the shaft frame from the driving shaft assembly when limiting the driving shaft assembly, so that the shaft frame can be used to limit and drive the driving shaft assembly to transfer, and at the same time will not affect the stability detection of the driving shaft assembly; By allowing the sleeve frame to be telescopically connected to the mobile frame, and by arranging a turntable and a pull rod on the mobile frame, the driving mechanism can simultaneously enable the driving shaft assembly to achieve angle change (angle change between the intermediate shaft and the universal joint) when driving the driving shaft assembly to rotate. Compared with a single rotation detection, this detection adds angle change, which can improve the detection effect of the driving shaft assembly; By arranging a telescopic frame on the vibration detection mechanism and hinge-connecting the telescopic frame with two sleeve frames, the vibration detection mechanism can better adapt to the angle change of the drive shaft assembly and the lifting and lowering of the drive mechanism.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please combine Figures 1 to 8 , a driving shaft assembly stability detection device, comprising: a base frame 1, a guide trough 2 for guiding the driving shaft assembly and a rotating wheel 3 rotatable and used to transfer the driving shaft assembly are arranged on the base frame 1, a first motor 7 is also arranged on the base frame 1, and circular gears are arranged on the output shaft of the first motor 7 and the shaft rod of the rotating wheel 3, and the two circular gears are meshed, and a plurality of shaft frames 4 for limiting the driving shaft assembly and capable of lifting and resetting are arranged on the rotating wheel 3, and a plurality of pairs of T-shaped rods 5 are arranged on the rotating wheel 3, and the plurality of pairs of T-shaped rods 5 respectively penetrate the corresponding shaft frames 4 and are slidably connected thereto, and a first spring 6 is sleeved on the plurality of pairs of T-shaped rods 5, and the two ends of the first spring 6 are respectively against the rotating wheel 3 and the shaft frame 4, and a movable driving mechanism is arranged on the rotating wheel 3; The driving mechanism includes two moving frames 10, on which sleeves 11 are slidably mounted, and on which transmission cylinders 12 matching the spline ends of the drive shaft assemblies are rotatably mounted. Transmission cylinders 12 are rotatably mounted on the two sleeves 11, and transmission teeth are arranged on the inner holes of the transmission cylinders 12 so as to mesh with the spline ends of the drive shaft assemblies on the universal joints. A third motor 13 is arranged on the corresponding sleeves 11, and a turntable 14 and a retractable drive rod are rotatably mounted on the corresponding moving frames 10, and a pull rod 15 is rotatably mounted on the turntable 14, and one end of the pull rod 15 is hinged to the corresponding sleeve 11, and the drive rod is composed of a sleeve and a telescopic rod. The sleeve of the driving rod is connected to the output shaft of the third motor 13 and is transmitted to the turntable 14 through a bevel gear. The telescopic rod of the driving rod is rotatably connected to the corresponding sleeve 11 and is transmitted to the corresponding transmission cylinder 12 through a bevel gear. In this way, the third motor 13 can not only drive the driving shaft assembly to rotate, but also realize the angle change when the driving shaft assembly rotates, so that the driving shaft assembly can adjust the angle by lifting one end when rotating, so as to make the stability detection more comprehensive. The side where the two moving frames 10 are close to each other is provided with a triangular block 21 that can squeeze the shaft frame 4 to descend.

[0021] Through the above technical scheme, a new drive shaft assembly stability detection device is formed. Compared with the traditional drive shaft assembly stability detection device, the drive shaft assembly can be automatically deployed and unloaded, making the stability detection of the drive shaft assembly more automated, eliminating the tediousness of manual deployment, and being more suitable for large-scale stability detection of drive shaft assemblies. At the same time, by arranging a shaft frame 4 that can be raised and lowered and reset on the rotating wheel 3, and arranging a triangular stop block 21 that can press the shaft frame 4 on the driving mechanism, the driving mechanism can separate the shaft frame 4 from the drive shaft assembly when limiting the drive shaft assembly, so that the shaft frame 4 can be used to limit and drive the transfer of the drive shaft assembly without affecting the stability detection of the drive shaft assembly, and when driving the drive shaft assembly to rotate, the angle change of the drive shaft assembly (the angle change between the intermediate shaft and the universal joint) can also be realized synchronously. Compared with a single rotation detection, this detection adds angle change, which can improve the detection effect of the drive shaft assembly.

[0022] A rotating hole is provided on the shaft of the rotating wheel 3, and a bidirectional screw rod 8 is rotatably installed in the rotating hole. A second motor 9 for driving the bidirectional screw rod 8 to rotate is provided on the base frame 1, and the output shaft of the second motor 9 is connected to one end of the bidirectional screw rod 8. The two ends of the bidirectional screw rod 8 respectively penetrate the two moving frames 10 and are threadedly connected with the two moving frames 10, thereby driving the two moving frames 10 to move closer to or away from each other. Two pairs of sliding rods are provided on the base frame 1, and the two pairs of sliding rods respectively penetrate the corresponding moving frames 10 and are slidably connected thereto, thereby ensuring that the two moving frames 10 can move smoothly and stably under the drive of the bidirectional screw rod 8.

[0023] The tops of the two sleeve frames 11 are hinged with the same telescopic frame 16, and a vibration detection mechanism is fixedly installed on the telescopic frame 16. The vibration detection mechanism includes a sleeve 17, and a push rod 18, a vibration sensor 20 and a second spring 19 are slidably installed in the sleeve 17. At the same time, an alarm can be set on the base frame 1, wherein the vibration sensor 20 can be connected to the alarm, and once the abnormal vibration amplitude of the drive shaft assembly is detected, an alarm can be issued. The second spring 19 is slidably sleeved outside the vibration sensor 20 and its two ends are respectively connected to the top of the push rod 18 and the top of the sleeve 17. The inner wall of the supporting rod 18 is abutted against the inner wall of the supporting rod 18, and the supporting rod 18 contacts the rotating driving shaft, so as to determine the stability of the driving shaft assembly by detecting the vibration amplitude of the driving shaft assembly during rotation. A spherical roller is provided at the bottom of the supporting rod 18, which not only can prevent the supporting rod 18 from causing wear to the rotating driving shaft assembly, but also the spherical shape of the roller can better adapt to the angle change of the driving shaft assembly during rotation. The vibration detection mechanism is connected to the two sleeve frames 11 through the telescopic frame 16, which can better adapt to the lifting and lowering of the transmission cylinder 12 and the angle change of the driving shaft assembly.

[0024] The implementation principle of a drive shaft assembly stability detection device in the embodiment of the present application is: This detection device can be placed at the end of the conveying equipment and used in conjunction with the sorting conveyor, or it can be used alone; When in use, the drive shaft assembly to be tested is sequentially placed into the guide trough 2, and then the first motor 7 drives the rotating wheel 3 to rotate. When the shaft frame 4 on the rotating wheel 3 is transferred to the discharge port of the guide trough 2, the drive shaft assembly to be tested will fall onto the shaft frame 4, and then the rotating wheel 3 drives the drive shaft assembly to the driving mechanism; The second motor 9 drives the bidirectional screw 8 to rotate, and the bidirectional screw 8 drives the two moving frames 10, the two sleeve frames 11 and the two transmission cylinders 12 to approach each other until the spline shafts at both ends of the drive shaft assembly are sleeved and meshed with them. At the same time, the two moving frames 10 will drive the two triangular blocks 21 to squeeze the current shaft frame 4 while moving. The shaft frame 4 is separated from the drive shaft assembly while squeezing the first spring 6 to avoid affecting the stability detection of the drive shaft assembly; The third motor 13 drives the turntable 14 and the corresponding transmission cylinder 12 to rotate through the driving rod. As the turntable 14 rotates, it drives the corresponding sleeve 11 and the transmission cylinder 12 to reciprocate and rise and fall through the pull rod 15. As the transmission cylinder 12 rotates, it also drives the drive shaft assembly to rotate, so that the universal joint of the drive shaft assembly and the intermediate shaft can continuously change the angle, so that the detection is more diverse. When the drive shaft assembly rotates at a changed angle, the abutment rod 18 and the spherical roller on the vibration detection mechanism will abut against the intermediate shaft of the drive shaft assembly under the push of the second spring 19, thereby detecting the vibration amplitude during rotation and determining the stability of the entire drive shaft assembly.
