Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to a durability detection tool for a motorcycle fuel tank lock plate. Background Art

[0002] The motorcycle fuel tank lock disc durability test tool is a device used to perform durability tests on motorcycle fuel tank lock discs. It is mainly composed of mechanical structure, control and detection systems, etc. It can simulate various working conditions of motorcycle fuel tank lock discs in actual use and evaluate the performance and reliability of the lock disc. After the motorcycle fuel tank cap is opened and closed many times, the sealing performance decreases. Conventional motorcycle fuel tank lock disc sealing performance test has the problem of low detection efficiency.

[0003] In response to the above problems, the prior art has proposed some solutions. For example, the invention patent with patent application number CN202123374378.2 discloses a motorcycle fuel tank cap durability test device, which includes a fuel tank mounting base, on which the fuel tank is fixed. The fuel tank mounting base is also provided with a linear cylinder, and a rotary cylinder is provided at the end of the piston rod of the linear cylinder. The driving end of the rotary cylinder is connected to the fuel tank cap fixing plate, which passes through the fuel tank cap fixing plate through an open coupling and is connected to the fuel tank cap. The fuel tank cap is arranged in a position corresponding to the fuel tank, and the linear cylinder and the rotary cylinder are connected to the control system through an air circuit; the control system controls the rotary cylinder to drive the key inserted into the fuel tank cap through the open coupling to unlock / lock the fuel tank cap, controls the linear cylinder to drive the fuel tank cap to open / close, and reads the drive data; although the above solution solves the problem of low detection efficiency, when testing the sealing performance of the fuel tank lock disk, the detection pressure applied each time cannot be consistent, which easily leads to inaccurate detection data. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle fuel tank lock plate durability testing tool to solve the problem of low detection efficiency in the existing motorcycle fuel tank lock plate sealing performance test, and at the same time solve the problem of inaccurate detection data caused by inconsistent detection pressure in the detection test.

[0005] To achieve the above object, the present invention provides the following technical solutions: The lock plate is fixed to the detection box, and the fixed base is installed on the detection box, and the fixed base is coaxial with the detection oil port, and the lock plate body is rotatably connected to the fixed base, and the lock plate body comprises a lock body, a sealing ring, a sealing spring, a lock tongue and a locking spring, the sealing ring and the sealing spring are coaxially slidably sleeved on the lock body, the lock tongue is slidably connected to the lock body, the sliding direction of the lock tongue is perpendicular to the axis of the lock body, and the locking spring is installed between the lock tongue and the lock body, a pressure sensor is installed in the detection box, and a proximity switch is installed at the farthest end of the sliding distance of the lock tongue, a pressurizing assembly is provided on the detection box, and a piston rod is provided on the pressurizing assembly, and two ends of the piston rod are respectively connected to the lock plate body and the detection box, a motor is installed on the mounting frame, and the mounting frame is provided with a pressure sensor. The cam is then driven by a spring to push the cam back into position so that the cam is in contact with the oil port and the cam is in contact with the oil port, and the cam is then driven by a spring to push the cam back into position so that the cam is in contact with the oil port and the cam is in contact with the oil port.

[0006] Preferably, the pressurizing assembly includes a piston cylinder and a leather cup, the piston cylinder is mounted on a detection box, an air storage chamber is provided in the detection box, a pressurizing chamber is provided in the piston cylinder, the lower end of the pressurizing chamber is communicated with the air storage chamber, the piston rod is slidably connected in the piston cylinder, the leather cup is mounted on the lower end surface of the piston rod, the leather cup is frustum-shaped, and the large end of the leather cup faces downward; when the lock disk body swings toward the oil port, the leather cup moves downward accordingly, compressing the air in the pressurizing chamber and transferring it to the air storage chamber, so that the air pressure in the air storage chamber increases, and the high-pressure gas acts on the lock disk body (such as the sealing ring, the lock tongue and other components), simulating the actual use. In the pressure environment during use (such as air pressure fluctuations inside the fuel tank), the design of the leather cup with the big end facing downwards allows its outer periphery to fit tightly against the inner wall of the piston cylinder when under pressure, and uses the elastic deformation of the rubber material to fill the gap, thereby preventing gas from leaking from the contact surface between the piston cylinder and the piston rod. At the same time, the leather cup, as an elastic medium, can convert the rigid thrust of the piston rod into a uniform air pressure load, preventing the lock disc body from bearing local impact loads, reducing abnormal wear or damage during the test, and ensuring the reliability of the test data of the motorcycle fuel tank lock disc durability test tooling, as well as the test accuracy and durability of the motorcycle fuel tank lock disc durability test tooling.

[0007] Preferably, a detection chamber is further provided in the detection box, the detection chamber is communicated with the detection oil port, a trigger switch is installed between the detection chamber and the air storage chamber, a trigger slot is provided on the trigger switch, a trigger block is slidably connected in the trigger slot, a trigger spring is installed in the trigger slot, two ends of the trigger spring are respectively connected to the trigger block and the inner wall of the trigger slot, one end of the trigger block away from the trigger spring is in contact with the lock tongue, a trigger channel is provided on the trigger switch and the trigger block, when the lock tongue is ejected, the trigger channel on the trigger block is coaxial with the trigger channel on the trigger switch, and the two ends of the trigger channel are respectively communicated with the detection chamber and the air storage chamber; when the lock tongue is not ejected (the lock disk is in a locked state), the trigger block Under the action of the trigger spring, it remains in place, the trigger channel is misaligned, and the detection chamber is isolated from the air storage chamber. When the lock disk body swings to be flush with the fixed base, the lock tongue slides outward and embeds into the oil port. At the same time, the lock tongue pushes the trigger block and compresses the trigger spring. The trigger block slides to a position coaxial with the trigger channel. The detection chamber and the air storage chamber are connected through the trigger channel. At this time, the air pressure in the air storage chamber can be transmitted to the detection chamber through the trigger channel, which avoids the problem that when the sealing ring is not in close contact with the oil port, the gas in the air storage chamber enters the detection chamber in advance and flows out through the gap between the oil port and the sealing ring, resulting in a decrease in the pressure in the detection chamber during detection, thereby ensuring the detection accuracy and reliability of the motorcycle tank lock disk durability detection tooling.

[0008] Preferably, a sealing surface is provided on the side where the leather cup contacts the inner wall of the piston cylinder, and the angle between the sealing surface and the inner wall of the piston cylinder is in the range of 15° to 30°; when the piston rod moves downward to compress the gas, the air pressure is transmitted to the sealing surface through the leather cup, and a radial expansion force (F1) is generated under the action of the angle, so that the leather cup fits tightly against the inner wall of the piston cylinder, thereby enhancing the sealing effect. If the sealing surface angle is too large (such as >30°), the contact area between the edge of the leather cup and the cylinder wall increases, and the friction force increases, resulting in rapid wear of the rubber material during high-frequency reciprocating motion, and even tearing (especially when there are tiny protrusions on the cylinder wall). If the angle is too small (such as <15°), stress concentration may cause edge cracking, shortening the service life of the leather cup, thereby ensuring the sealing reliability and durability of the motorcycle tank lock plate durability test tooling.

[0009] Preferably, a support ring is coaxially provided on the sealing surface, and the outer wall of the support ring is slidably connected to the inner wall of the piston cylinder, and a spring coil is provided in the support ring; when the piston rod drives the leather cup to reciprocate, the support ring bears the radial load (such as gas pressure, friction), so as to avoid the leather cup from bearing shear force alone and reduce the deformation stress of the rubber material. The spring coil (such as a metal spring, a rubber elastic ring) is installed inside the support ring to provide a continuous radial preload, so as to avoid the problem that the leather cup sealing surface needs to bear gas pressure and friction independently when there is no support ring, which is easy to cause edge folding and tearing due to excessive deformation. The support ring reduces the radial stress of the leather cup by about 40% by sharing the load, avoids cracks in the rubber material due to fatigue, and ensures the sealing accuracy and reliability of the motorcycle tank lock plate durability test tooling.

[0010] Preferably, a valve body is installed between the pressurizing chamber and the air storage chamber, the central axis of the valve body is parallel to the central axis of the piston cylinder, the inner wall of the valve body is conical, and the large end of the cone faces upward, and a valve ball and a buffer spring are provided in the valve body, the valve ball contacts the inner wall of the valve body, and the two ends of the buffer spring are respectively connected to the upper end of the valve ball and the upper end of the valve body; traditional planar valves (such as ball valves and flat plate valves) are prone to gaps due to the embedding of impurities (such as metal debris, oil condensation) or wear of the valve ball due to the flat sealing surface, resulting in leakage in the pressure holding stage, and after the conical valve body and the buffer spring are matched, when the motorcycle fuel tank lock disk durability test tooling performs simulated vibration, the impact energy generated by the valve ball itself is absorbed, thereby avoiding the gas pressure in the air storage chamber from leaking toward the pressurizing chamber, which in turn causes the problem of reduced pressure in the test chamber during detection, thereby ensuring the detection accuracy and reliability of the motorcycle fuel tank lock disk durability test tooling.

[0011] Preferably, a cam is installed on the rotating shaft of the motor, and a slide is installed on the lower end surface of the push rod. The slide is arc-shaped, and the cam is rollingly connected to the lower end surface of the slide; the motor drives the cam to rotate, and the cam pushes the slide and then drives the push rod to move. After the lock disk body is closed, the motor continues to drive the cam to rotate. At this time, the cam will drive the motor to vibrate. The vibration of the cam simulates the pulse load that the lock disk bears when the motorcycle passes over bumpy roads, avoiding the problem of a single detection environment, resulting in inconsistent test results with data in actual usage scenarios, and ensuring the reliability of the test data of the motorcycle tank lock disk durability test tooling.

[0012] Preferably, a permanent magnet is installed on the upper end surface of the skateboard, and the mounting frame is made of magnetic material; when the push rod pushes the lock disk body to swing to a position flush with the fixed base, the permanent magnet drives the skateboard to move toward the mounting frame and fit on the mounting frame. At this time, the cam will be out of contact with the lower end surface of the skateboard, avoiding excessive friction between the cam and the skateboard when the motor drives the cam to rotate at high speed, resulting in wear of the skateboard and the cam, thereby ensuring the service life of the motorcycle tank lock disk durability test tooling.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a pressurizing assembly on the detection box, and a piston rod on the pressurizing assembly. The two ends of the piston rod are respectively connected to the lock disk body and the detection box. When the lock disk body swings toward the oil port, the piston rod uses the rotational force of the lock disk body to apply gas pressure to the detection box, and detects the gas pressure in the detection box through a pressure sensor. This avoids the problem of inaccurate test data caused by inconsistent test pressure in the motorcycle fuel tank lock disk sealing performance test, and ensures the reliability of the test data of the motorcycle fuel tank lock disk durability test tooling.

[0014] 2. The present invention installs a trigger switch between the detection chamber and the air storage chamber. When the lock disk body swings to be flush with the fixed base, the lock tongue pushes the trigger block and compresses the trigger spring. The trigger block slides to the coaxial position of the trigger channel, and the detection chamber and the air storage chamber are connected through the trigger channel. At this time, the air pressure in the air storage chamber can be transmitted to the detection chamber through the trigger channel, avoiding the problem that when the sealing ring is not in close contact with the oil port, the gas in the air storage chamber flows out through the gap between the oil port and the sealing ring, resulting in a decrease in the pressure in the detection chamber during detection, thereby ensuring the detection accuracy and reliability of the motorcycle tank lock disk durability detection tooling.

[0015] 3. The present invention has a cam installed on the rotating shaft of the motor and a slide installed on the lower end surface of the push rod; the motor drives the cam to rotate, and the cam pushes the slide and then drives the push rod to move. After the lock disk body is closed, the motor continues to drive the cam to rotate. At this time, the cam will drive the motor to vibrate. The vibration of the cam simulates the pulse load that the lock disk bears when the motorcycle passes over bumpy roads, avoiding the problem of a single detection environment causing the test results to be inconsistent with the data of the actual usage scenario, thereby ensuring the reliability of the test data of the motorcycle tank lock disk durability test tooling.

A valve ball 802 and a buffer spring 803 are provided in the valve body 801. The valve ball 802 contacts the inner wall of the valve body 801. The two ends of the buffer spring 803 are respectively connected to the upper end of the valve ball 802 and the upper end of the valve body 801. The piston rod 602 is slidably connected to the piston cylinder 601. Inside, a leather cup 603 is installed on the lower end surface of the piston rod 602. The leather cup 603 is in a truncated cone shape, and the large end of the leather cup 603 faces downward. A sealing surface 701 is provided on the side of the leather cup 603 that contacts the inner wall of the piston cylinder 601. The angle between the sealing surface 701 and the inner wall of the piston cylinder 601 is 20 degrees. A support ring 702 is coaxially provided on the sealing surface 701. The outer wall of the support ring 702 is slidably connected to the inner wall of the piston cylinder 601. A spring coil 703 is provided in the support ring 702. A detection chamber 204 is also provided in the detection box 201. The detection chamber 204 is connected to the detection oil port 202. A trigger switch 605 is installed between the detection chamber 204 and the air storage chamber 203. A trigger groove 606 is provided on the trigger switch 605.

A trigger channel 609 is provided on the trigger switch 605 and the trigger block 607. When the lock tongue is pushed out, the trigger channel 609 on the trigger block 607 is coaxial with the trigger channel 609 on the trigger switch 605. The two ends of the trigger channel 609 are respectively connected to the detection chamber 204 and the air storage chamber 203. The two ends of the piston rod 602 are respectively connected to the lock disk body 4 and the detection box 201. The motor 503 is installed on the mounting frame 1, and the push rod 504 is slidably connected to the mounting frame 1. The cam 505 is installed on the rotating shaft of the motor 503.A slide 506 is mounted on the lower end surface of the push rod 504. The slide 506 is arc-shaped, and the cam 505 is in rolling connection with the lower end surface of the slide 506. A permanent magnet 507 is mounted on the upper end surface of the slide 506, and the mounting bracket 1 is made of magnetic material. As the lock plate body 4 swings toward the oil port 202, the piston rod 602 uses the rotational force of the lock plate body 4 to apply gas pressure to the detection box 201. After the lock tongue pops out and moves to the farthest end, the proximity switch 502 is turned on. At this time, the pressure sensor 501 detects the gas pressure in the detection box 201, avoiding the problem of inconsistent detection pressure and resulting in inaccurate test data in the motorcycle tank lock plate sealing performance test, and ensuring the reliability of the test data of the motorcycle tank lock plate durability test tool.

[0019] While working, see Figures 1 to 5 After the motor 503 is started, the motor 503 drives the cam 505 to rotate. The cam 505 uses its own contour to push the lower end surface of the arc slide 506, so that the push rod 504 moves toward the lock disk body 4 and pushes the lock disk body 4. At this time, the lock disk body 4 is pressurized and rotates along the connection between the lock disk body 4 and the fixed base 3. During the rotation of the lock disk body 4, the piston rod 602 is pressurized to drive the leather cup 603 to slide downward in the piston cylinder 601. The leather cup 603 squeezes the gas in the pressurized chamber 604. At this time, the high-pressure gas in the pressurized chamber 604 pushes the valve ball 802 and compresses the buffer spring 803, so that the valve body 801 connects the pressurized chamber 604 with the gas storage chamber 203 and pushes the high-pressure gas into the gas storage chamber 203. During the swinging process of the lock disk body 4, the lock tongue receives the oil port The reaction force of the inner wall of 202 squeezes to overcome the resistance of the locking spring and contracts. When the lock disk body 4 swings to be flush with the fixed base 3, the lock tongue loses the restraint of the inner wall of the oil port 202, pushes out in the direction away from the lock body and embeds into the connection between the detection box 201 and the oil port 202.

The detection chamber 204 is connected to the air storage chamber 203 through the trigger channel 609. At this time, the air pressure in the air storage chamber 203 can be transmitted to the detection chamber 204 through the trigger channel 609. At the same time, when the lock tongue pops out and moves to the farthest end, the proximity switch 502 is turned on. At this time, the pressure sensor 501 detects the gas pressure in the detection box 201.

[0020] It is worth noting that when the push rod 504 pushes the lock disk body 4 to swing to a position flush with the fixed base 3, the permanent magnet 507 drives the slide plate 506 to move toward the mounting frame 1 and fits on the mounting frame 1, so that the cam 505 is out of contact with the lower end surface of the slide plate 506. Further, the motor 503 drives the cam 505 to rotate at a high speed to generate vibration. The vibration of the cam 505 simulates the pulse load that the lock disk is borne when the motorcycle passes over a bumpy road.
