Ball pin torque detection anti-slip mechanism

Abstract

This utility model discloses a ball pin torque detection anti-slip mechanism, relating to the field of ball pin torque detection technology. It includes a detection platform, a transmission disc, a detection plate, a placement plate, a transmission belt, and a detection sensor. A rotating rod is rotatably connected to the top of the detection platform. The transmission disc is fixed to the top of the rotating rod. The placement plate is fixed to the top of the transmission disc. By setting a gear-type detection plate driven by the transmission belt and linked to the ball pin, and using a detection sensor to non-contactly monitor its teeth to simulate pulse signals, this design can accurately determine in real time whether slippage occurs between the ball pin clamp and the ball pin. Once no pulse signal is detected, it indicates that the ball pin is not rotating synchronously with the motor, and the system can immediately issue an alarm to remind staff to intervene, effectively preventing the outflow of defective products and significantly improving the reliability of the detection results and the level of production quality control.

Description

Technical Field

[0001] This utility model relates to the field of ball pin torque detection technology, specifically to a ball pin torque detection anti-slip mechanism. Background Technology

[0002] Ball joint torque testing is a key quality control process in the automotive and machinery industries. It is mainly used to measure the rotational torque of ball joints in assemblies such as steering systems and suspension systems. This torque value is directly related to the operation feel, mechanical performance and safety reliability of the assembly. Therefore, the accuracy and stability of the test are extremely important, making it an indispensable inspection link in the production process.

[0003] Currently, the automated ball pin torque detection method places the ball head of the ball pin to be tested in a clamp consisting of grippers. The grippers are closed by a cylinder or hydraulic cylinder to clamp the ball head. Then, the drive motor drives the entire clamp and the clamped ball pin to rotate together through the transmission mechanism. The torque data during the rotation process is collected in real time by the sensor and compared with the preset tolerance range to determine whether the product is qualified.

[0004] However, the reliability of its detection results is highly dependent on the static friction between the gripper and the ball pin surface. In actual production, when the gripper wears down due to long-term use, the ball pin surface is covered with oil or grease, or the product itself has excessive torque deviation, slippage between the gripper and the ball pin is very likely to occur. Once slippage occurs, although the motor rotates normally, the ball pin is not effectively driven or completely stationary. The sensor detects only the slippage friction torque rather than the actual ball pin rotation torque. This will cause the system to mistakenly judge unqualified products as qualified products, resulting in defective products being released and posing a serious quality risk. Utility Model Content

[0005] The purpose of this utility model is to provide a ball pin torque detection anti-slip mechanism to solve the technical problem in the prior art that slippage between the gripper and the ball pin is very easy to occur when the gripper wears down due to long-term use, when oil or grease adheres to the ball pin head surface, or when the torque of the product itself is too large.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution: A ball pin torque detection anti-slip mechanism includes a detection platform, a transmission disc, a detection plate, a placement plate, a transmission belt, and a detection sensor. A first rotating rod is rotatably connected to the top of the detection platform. The transmission disc is fixed to the top of the first rotating rod. The placement plate is fixed to the top of the transmission disc. A second rotating rod is also rotatably connected to the top of the detection platform. The detection plate is fixed to the top of the second rotating rod. The transmission belt is rotatably connected between the transmission disc and the second rotating rod. The detection sensor is fixed to the top of the detection platform and is located on one side of the detection plate.

[0007] As a further embodiment of this utility model: a lifting cylinder is provided on the side of the testing platform; a motor is fixedly connected to the bottom of the lifting cylinder; a torque sensor is fixedly connected to the bottom of the motor; a ball pin clamp is fixedly connected to the bottom of the torque sensor, and the ball pin clamp is located above the transmission disc.

[0008] As a further embodiment of this utility model: an electric slide rail is provided on the side end of the transmission disc; a sliding plate is slidably connected to the side end of the electric slide rail; and a cleaning brush is fixedly connected to the bottom end of the sliding plate.

[0009] The beneficial effects of this invention are as follows: By setting up a gear-type detection disc driven by a transmission belt and linked to the ball pin, and using a detection sensor to perform non-contact monitoring of its teeth to simulate the generation of pulse signals, an independent slippage monitoring system is constructed. This design can determine in real time and accurately whether slippage occurs between the ball pin clamp and the ball pin. Once no pulse signal is detected, it indicates that the ball pin is not rotating synchronously with the motor, and the system can immediately issue an alarm to remind the staff to intervene. This fundamentally avoids false detection and misjudgment of torque data caused by slippage, effectively prevents the outflow of defective products, and greatly improves the reliability of detection results and the level of production quality control.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figures 1-3 As shown, a ball pin torque detection anti-slip mechanism includes a detection platform 1, a transmission disc 2, a detection plate 3, a placement plate 4, a transmission belt 5, and a detection sensor 6. A first rotating rod is rotatably connected to the top of the detection platform 1. The transmission disc 2 is fixedly connected to the top of the first rotating rod. The placement plate 4 is fixedly connected to the top of the transmission disc 2. A second rotating rod is also rotatably connected to the top of the detection platform 1. The detection plate 3 is fixedly connected to the top of the second rotating rod. The transmission belt 5 is rotatably connected between the transmission disc 2 and the second rotating rod. The detection sensor 6 is fixedly connected to the top of the detection platform 1 and is located on one side of the detection plate 3.

[0014] The bottom end of the ball pin will contact the placement plate 4. When the ball pin is driven by the motor 8, the rotation of the ball pin will cause the transmission disk 2 to rotate. The first rotating rod can limit the position of the transmission disk 2. The rotation of the transmission disk 2 will cause the transmission belt 5 to rotate. The rotation of the transmission belt 5 will cause the second rotating rod to rotate together. The second rotating rod will cause the detection disk 3 to rotate. The detection sensor 6 is located on one side of the detection disk 3 to detect the rotation data. The torque sensor 9 works in conjunction with the detection sensor 6. The detection sensor 6 performs non-contact monitoring of the teeth of the detection disk 3 to simulate the generation of pulse signals, thus constructing an independent slippage monitoring system. This design can determine in real time and accurately whether slippage occurs between the ball pin clamp 10 and the ball pin. Once no pulse signal is detected, it indicates that the ball pin is not rotating synchronously with the motor 8. The system can immediately issue an alarm to remind the staff to intervene. The side end of the testing platform 1 is provided with a lifting cylinder 7; the bottom end of the lifting cylinder 7 is fixedly connected to a motor 8; the bottom end of the motor 8 is fixedly connected to a torque sensor 9; the bottom end of the torque sensor 9 is fixedly connected to a ball pin gripper 10, which is located above the transmission disc 2.

[0015] During operation, the staff places the ball pin on the ball pin clamp 10 and clamps and fixes the ball pin. At this time, the lifting cylinder 7 moves the ball pin downward and the motor 8 rotates the ball pin clamp 10 and the ball pin together. The rotation of the ball pin will drive the placement plate 4 to rotate. The cooperation between the lifting cylinder 7 and the ball pin clamp 10 can automatically detect the ball pin. The transmission disc 2 is provided with an electric slide rail 11 on its side; a slide plate 12 is slidably connected to the side of the electric slide rail 11; and a cleaning brush 13 is fixedly connected to the bottom of the slide plate 12.

[0016] After a set of ball pins are tested, the slide plate 12 is slid by the electric slide rail 11. The sliding of the slide plate 12 causes the cleaning brush 13 to slide, cleaning the surface of the placement plate 4 and preventing dust, oil and other impurities from remaining on the surface of the placement plate 4, which would affect the ball pins from slipping on the placement plate 4. The working principle of this utility model is as follows: During operation, the operator places the ball pin on the ball pin clamp 10, which clamps and fixes the ball pin. At this time, the lifting cylinder 7 moves the ball pin downwards, and the motor 8 rotates the ball pin clamp 10 and the ball pin together. The rotation of the ball pin drives the placement plate 4 to rotate. The cooperation between the lifting cylinder 7 and the ball pin clamp 10 allows for automatic detection of the ball pin. The bottom end of the ball pin contacts the placement plate 4. When the ball pin is driven by the motor 8, its rotation causes the transmission disc 2 to rotate. The first rotating rod can limit the position of the transmission disc 2. The rotation of the transmission disc 2 then causes the transmission belt 5 to rotate, which in turn causes the second rotating rod to rotate. The second rotating rod then rotates the detection disc 3, and the detection sensor 6... Rotation data is detected on one side of the detection disk 3. Torque sensor 9 works in conjunction with detection sensor 6. Detection sensor 6 performs non-contact monitoring of the teeth of detection disk 3 to simulate the generation of pulse signals, thus constructing an independent slippage monitoring system. This design can determine in real time and accurately whether slippage occurs between the ball pin clamp 10 and the ball pin. Once no pulse signal is detected, it indicates that the ball pin is not rotating synchronously with the motor 8, and the system can immediately issue an alarm to remind the staff to intervene. After a set of ball pins is detected, the slide plate 12 is slid by the electric slide rail 11. The sliding of the slide plate 12 causes the cleaning brush 13 to slide, cleaning the surface of the placement plate 4 and preventing dust, oil, and other impurities from remaining on the surface of the placement plate 4, which could affect the slippage of the ball pin on the placement plate 4.
