Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a four-axis force measuring device for automotive air conditioning vents. Background Technology

[0002] Currently, almost all cars are equipped with an air conditioning system to cool, heat, and ventilate the air inside the car. The car has air conditioning vents to exchange air inside the car and to deliver cold or hot air into the car.

[0003] The force measurement of automotive air conditioning vent paddle shifters primarily relies on a six-axis robot controlling the paddles. Before testing, each axis collaboratively calibrates the equipment to ensure motion precision and the measurement accuracy of the onboard six-dimensional force sensor. Simultaneously, it positions the paddle shifter and adapts the appropriate end effector based on the paddle's shape and operating method, laying the foundation for subsequent testing. During testing, as the paddle shifter approaches, some axes adjust their positions while the remaining axes calibrate their end effector posture to achieve smooth contact with the paddle. During the shifting motion, each axis adjusts in real-time according to the paddle's trajectory and angle changes to detect the force value of the paddle.

[0004] Regarding the aforementioned technologies, six-axis robots occupy a large space and require a long debugging time. In actual testing, complex programming is required to complete the inspection task, which can easily lead to cumbersome operation procedures and low product inspection efficiency. As the automotive manufacturing industry continues to demand higher production efficiency, there is an urgent need for a more efficient and convenient inspection device to solve the above problems. Utility Model Content

[0005] To improve the convenience of device testing, this application provides a four-axis force measuring device for automotive air conditioning vents.

[0006] This application provides a four-axis force measuring device for automotive air conditioning vents, employing the following technical solution:

[0007] A four-axis force measuring device for an automotive air conditioning vent includes a testing platform. The upper end of the testing platform is provided with a mounting platform and a carrier for placing the air conditioning vent to be tested. The air conditioning vent has a paddle for adjusting the airflow angle. The mounting platform has a paddle holder and a four-axis structure. A motor is installed within the four-axis structure to drive the paddle holder to move along a triangular coordinate system. The paddle holder has a paddle for actuating the paddle, and the paddle holder drives the paddle to rotate laterally. A force sensor is provided between the paddle and the paddle holder to detect the magnitude of the thrust used when the paddle pushes the paddle. The carrier has an adjusting component for adjusting the initial position of the paddle and a positioning component for fixing the air conditioning vent.

[0008] By adopting the above technical solution, the operator places the air conditioner vent on the platform and adjusts the lever to a uniform position using the adjusting components. With the support of the testing platform, the platform supports and fixes the air conditioner vent through the positioning components, facilitating subsequent testing. The mounting platform supports and fixes the four-axis structure. Driven by the motor, the four-axis structure moves the lever seat along the triangular coordinate system. The lever seat causes the lever to rotate laterally, allowing the lever to approach and push the lever from multiple angles. The force sensor detects the magnitude of the thrust through the lever, thus completing the test. The four-axis structure is simple and convenient to operate, which helps improve the testing efficiency and convenience of the device.

[0009] Optionally, the four-axis structure includes a vertical wall, a horizontal arm one, a horizontal arm two, and a horizontal arm three. The vertical wall is vertically mounted on the mounting platform. The horizontal arm one is slidably connected to the vertical arm. The horizontal arm two is rotatably connected to the end of the horizontal arm one away from the vertical arm. The horizontal arm three is rotatably connected to the end of the horizontal arm two away from the horizontal arm one. The lever seat is rotatably connected to the side of the horizontal arm three away from the horizontal arm two.

[0010] By adopting the above technical solution, the mounting platform supports the vertical wall, and the vertical wall supports the first, second and third horizontal arms. The first horizontal arm drives the lever plate to move vertically through the second and third horizontal arms. The second and third horizontal arms drive the lever plate to move in any direction on the horizontal plane, which improves the convenience of device operation and expands the movement range of the lever plate, which is conducive to improving the detection efficiency of the device.

[0011] Optionally, the positioning element includes a positioning pin, which is arranged along the circumference of the platform.

[0012] By adopting the above technical solution, when the operator aligns the air conditioner vent with the positioning pin and places it on the platform, the platform positions and guides the air conditioner vent through the positioning pin, which helps to improve the convenience and accuracy of air conditioner vent installation.

[0013] Optionally, the positioning element may further include a locking block adapted to the side of the air conditioning vent, the locking block being arranged circumferentially along the platform.

[0014] By adopting the above technical solution, when the operator places the air conditioner vent on the platform, the locking block engages with the air conditioner vent, and the platform fixes and limits the air conditioner vent through the locking block, which helps to improve the installation stability of the air conditioner vent.

[0015] Optionally, the adjusting component includes a first moving rod and a second moving rod. The first moving rod is parallel to the length direction of the platform, and the second moving rod is parallel to the width direction of the platform. The lower ends of both the first and second moving rods are provided with sliders. The platform is provided with a slide rail along the circumference to accommodate sliders. The lower ends of both the first and second moving rods are provided with elastic elements between them and sliders. In their natural state, the elastic elements push the first and second moving rods away from sliders.

[0016] By adopting the above technical solution, the slide rail limits and guides the slider one, and supports and guides the sliding rod one and the sliding rod two through the slider one. The operator moves the lever to the preset position by sliding the sliding rod one and the sliding rod two. Under the pushing action of the elastic element one, the sliding rod one and the sliding rod two move away from the slider, providing space for the lever to move.

[0017] Optionally, the adjusting component includes push rod one and push rod two, push rod one and push rod two are arranged perpendicularly, and push rod one is set outside push rod two. Push rod one and push rod two are each provided with slider two below push rod one and push rod two. Slider two is located inside the slide rail and fits against the inner wall of the slide rail. Elastic element two is provided between push rod one, push rod two and slider two. In its natural state, elastic element two pushes push rod one and push rod two away from slider two.

[0018] By adopting the above technical solution, the slide rail limits and guides the second slider, and the second slider supports and guides the first and second push rods. The operator pushes the first and second push rods at the same time, and the first and second push rods cooperate to push the lever. The first push rod slides along the length of the second push rod so as to push the slider completely to the preset position, which helps to improve the ease of operation of the device.

[0019] Optionally, one end of the paddle back force sensor is provided with a positioning port for engaging with the paddle.

[0020] By adopting the above technical solution, when the lever moves, it engages with the paddle through the positioning port. The lever positions and pushes the paddle through the positioning port, which helps to improve the accuracy of the contact between the lever and the paddle.

[0021] Optionally, the dial plate is slidably connected to positioning blocks on both sides of the positioning port. Bolts are provided on the positioning blocks. The bolts pass through the positioning blocks and are threadedly connected to the dial plate. The dial plate has a through hole in the transverse direction. The bolts pass through the through hole and are threadedly connected to nuts.

[0022] By adopting the above technical solution, the width of the positioning opening is adjusted by adjusting the distance between the positioning blocks, and the positioning blocks are fixed by bolts and nuts, thereby fixing the width of the positioning opening to accommodate different shaped levers, which helps to improve the applicability of the device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The operator places the air conditioner vent on the platform and adjusts the lever to a uniform position using the adjustment mechanism. With the support of the testing platform, the platform supports and fixes the air conditioner vent through the positioning mechanism, facilitating subsequent testing. The mounting platform supports and fixes the four-axis structure. Driven by the motor, the four-axis structure moves the lever seat along the triangular coordinate system. The lever seat causes the lever to rotate laterally, allowing the lever to approach and push the lever from multiple angles. The force sensor detects the magnitude of the thrust through the lever, thus completing the test. The four-axis structure is simple and convenient to operate, which helps improve the testing efficiency and convenience of the device.

[0025] 2. The mounting platform supports the vertical wall, and the vertical wall supports the first horizontal arm, the second horizontal arm, and the third horizontal arm. The first horizontal arm drives the lever plate to move vertically through the second and third horizontal arms. The second and third horizontal arms drive the lever plate to move in any direction on the horizontal plane, which improves the convenience of device operation and expands the range of movement of the lever plate, which is conducive to improving the detection efficiency of the device.

[0026] 3. When the operator places the air conditioner vent on the platform, the locking block engages with the air conditioner vent. The platform uses the locking block to fix and limit the air conditioner vent, which helps to improve the installation stability of the air conditioner vent. Attached Figure Description

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses a four-axis force measuring device for automotive air conditioning vents.

[0035] Example 1

[0036] Reference Figure 1 A four-axis force measuring device for an automotive air conditioning vent includes a testing platform 1, on which a carrier platform 2 is provided for installing the air conditioning vent. The carrier platform 2 is provided with a positioning component 3, which includes a positioning pin 31. The positioning pin 31 is installed at both ends of the carrier platform 2 along its length. When the operator places the air conditioning vent on the carrier platform 2, the positioning pin 31 guides the air conditioning vent, so that the air conditioning vent is installed directly opposite the carrier platform 2, which helps to improve the convenience and accuracy of the air conditioning vent installation.

[0037] The positioning component 3 also includes a locking block 32, which is installed at both ends of the platform 2 along the width direction. When the air conditioner outlet is installed with the platform 2, the locking block 32 engages with the side of the air conditioner outlet. The platform 2 fixes the air conditioner outlet with the locking block 32, reducing the probability of the air conditioner outlet falling off the platform 2 during the testing process, which helps to improve the stability of the air conditioner outlet installation and operation.

[0038] The platform 2 is equipped with an adjusting component, which includes a first moving rod 23 and a second moving rod 24. The first moving rod 23 is parallel to the length direction of the platform 2, and the second moving rod 24 is parallel to the width direction of the platform 2. The lower ends of both the first moving rod 23 and the second moving rod 24 along the length direction are equipped with sliders 22. The platform 2 is equipped with a slide rail 21 along the circumference to accommodate the sliders 22. The slide rail 21 guides and limits the sliders 22, thereby supporting and guiding the first moving rod 23 and the second moving rod 24.

[0039] Each of the movable lever 23 and movable lever 24 is equipped with an elastic element 1 between itself and the slider 22. In its natural state, the elastic element 1 tends to push the movable lever 23 away from the slider. The operator presses down and pushes the movable levers 23 and 24, moving the paddle to the same preset position. Under the pushing action of the elastic element 1, the movable levers 23 and 24 are higher than the paddle, providing space for the paddle plate 47 to move.

[0040] The testing platform 1 is also equipped with a mounting platform 4, which has a four-axis structure. The four-axis structure contains a motor to drive the operation of the four-axis structure. The four-axis structure includes a vertical arm 41, a first horizontal arm 42, a second horizontal arm 43, and a third horizontal arm 44. The vertical arm 41 is vertically mounted on the mounting platform 4. The first horizontal arm 42 is slidably connected to the vertical arm 41. The second horizontal arm 43 is rotatably connected to the end of the first horizontal arm 42 away from the vertical arm 41. The third horizontal arm 44 is rotatably connected to the end of the second horizontal arm 43 away from the first horizontal arm 42. The mounting platform 4 supports the first horizontal arm 42, the second horizontal arm 43, and the third horizontal arm 44 through the vertical arm 41. The four-axis structure is small in size and simple to operate, which helps to improve the convenience of device operation.

[0041] A lever seat 45 is rotatably connected to the lower end of the horizontal arm 44. A lever 47 is provided below the lever seat 45. The lever seat 45 drives the lever 47 to rotate laterally, so that the lever 47 can always face the lever with a plane. A force sensor 46 is provided between the lever seat 45 and the lever 47. The operator adjusts the lever to the same position through the adjustment component, drags the horizontal arm 44 to move the lever 47 between the lever and the air conditioner outlet. The lever 47 moves the lever to one side of the air conditioner installation port along the length or width direction. At this time, the device records the position. Under the drive of the motor, the lever 47 moves the lever to the opposite side along the length or width direction. The force sensor 46 detects the magnitude of the force required to move the lever through the lever 47, thereby completing the detection.

[0042] Positioning blocks 472 are slidably connected to both sides of the lever 47, which is away from the force sensor 46. Bolts 473 are threaded onto the positioning blocks 472. The lever 47 has a through hole along its lateral direction to accommodate the bolts 473. The bolts 473 pass through the positioning blocks and are threaded onto the lever 47. After passing through the lever 47, the bolts 473 are threaded onto a nut 474. The two positioning blocks 472 form a positioning opening 471 for engaging with the lever. The operator can adjust the position of the bolts 473 to adjust the width of the positioning opening 471, thereby accommodating levers of different shapes and improving the applicability of the device.

[0043] The implementation principle of the four-axis force measuring device for an automotive air conditioning vent in this embodiment is as follows: Under the support of the testing platform 1, the operator places the air conditioning vent on the platform 2 for fixation. The operator then moves the lever to a preset position by adjusting the lever and drags the cross arm 44 to move the lever 47 to the lever position, so that the positioning port 471 is directly engaged with the lever. Driven by the motor, the lever 47 moves the lever to one side of the air conditioning vent along its length or width. After the device records the position, the motor drives the lever 47 again to move the lever to the opposite position. The force sensor 46 detects the force required to move the lever through the lever 47, thereby completing the detection. The four-axis linkage, while reducing the size, performs a complete detection of the lever, which is beneficial to improving the detection efficiency and convenience of the device.

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that push rod 26 and push rod 27 are slidably connected on the platform 2.

[0046] Push rod 1 26 and push rod 27 are set perpendicularly. Push rod 1 26 is sleeved on the outside of push rod 27 and slides along the length of push rod 27. Slider 25 is provided below both ends of push rod 1 26 and push rod 27 along the length direction. Slider 25 is located inside slide rail 21. Push rod 1 26 and push rod 27 move along slide rail 21 through slider 25. Slide rail 21 supports and guides push rod 1 26 and push rod 27 through slider 25.

[0047] Both push rod 26 and push rod 27 are equipped with an elastic element 2 between them and slider 25. The elastic element 2 can be a spring. In its natural state, the spring pushes push rod 26 and push rod 27 away from the slider. The operator can move the lever to the preset position by pressing and moving push rod 26 and push rod 27. At the same time, push rod 26 or push rod 27 can be pushed individually to move the lever to the preset position completely. Under the pushing action of the elastic element 2, push rod 1 and push rod 2 are higher than the lever, so that the lever 47 can move, which helps to improve the ease of operation of the device.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
