Description

Technical Field

[0001] This utility model relates to the field of automotive gas spring processing technology, and in particular to a device for detecting the number of extension and retraction cycles of an automotive gas spring. Background Technology

[0002] Automotive gas springs are springs that utilize the elasticity of air by filling a retractable, sealed container with compressed air. They are commonly known as airbags, airbag cylinders, or bellows cylinders. Automotive gas springs have ideal non-linear elastic characteristics; with the addition of a height adjustment device, the vehicle height does not change with the load, and the spring stiffness can be designed to be lower, resulting in good ride comfort.

[0003] Conventional automotive gas spring testing equipment typically tests one gas spring at a time. However, when the production volume of the same batch is large, the number of samples to be inspected will increase. Testing each one individually is time-consuming, and the cost of adding testing equipment will also increase accordingly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for detecting the number of extension and retraction cycles of an automotive gas spring, thereby solving the problems mentioned in the background section.

[0005] A device for detecting the number of extension and retraction cycles of an automotive gas spring includes a worktable, a drive disk driven by a motor is installed in the middle of the worktable, an adjusting arm that can be limited by a pin is slidably arranged in the middle of the drive disk, and a drive shaft is rotatably installed at one end of the adjusting arm.

[0006] Two opposing movable plates are installed between the two side plates of the workbench. The central opening of the movable plate is slidably connected to the drive shaft. Fixed plates are provided on both sides of the movable plate. A limiting part is installed on the fixed plate. A movable sleeve that is rotatably connected to the fixed plate is provided around the limiting part.

[0007] The workbench has screws that can be positioned by nuts passing through the middle of the two side plates. A slider is fixedly installed at one end of the screw. The slider slides along the guide rail fixed on the workbench. A limiting part two is also installed on the slider. A movable sleeve two that is rotatably connected to the slider is provided around the limiting part two.

[0008] By adopting the above technical solution, two samples from different batches of automotive gas springs can be tested simultaneously, improving the efficiency of random inspection.

[0009] Multiple through holes are evenly opened on the adjusting arm, and a threaded groove is opened at the sliding groove in the middle of the drive disk, so that the pin can be screwed into the threaded groove after passing through the adjusting arm.

[0010] By adopting the above technical solution, it is possible to make adjustments according to different specifications of automotive gas springs.

[0011] The outer ring of the drive shaft is recessed in the middle, and the opening in the middle of the moving plate is correspondingly located in the recessed part of the outer ring of the drive shaft.

[0012] By adopting the above technical solution, the drive shaft can stably drive the moving plate to reciprocate.

[0013] The fixed plates on both sides of the movable plate are offset from the center point of the movable plate.

[0014] By adopting the above technical solution, the mounting parts of the two automotive gas springs are prevented from coming into contact, thus avoiding interference with normal testing.

[0015] One set of movable sleeves on one side of the movable plate and its nearest set of movable sleeves are on a straight line parallel to the slide rod.

[0016] By adopting the above technical solution, the automotive gas spring can be placed parallel to the slide bar, which facilitates subsequent testing.

[0017] The beneficial effects of this utility model's automotive gas spring extension cycle count detection device are:

[0018] Based on the dimensions and length of the automotive gas spring to be tested, first adjust the position of the slider on the guide rail, then rotate the nut on the screw to restrict the screw's movement, and then adjust the position of the adjusting arm on the drive plate. A pin is then threaded through the through-hole on the adjusting arm and threaded into the threaded hole on the drive plate to limit the adjusting arm. The center distance between the drive shaft and the drive plate is then adjusted. The drive motor drives the drive plate to rotate, and the drive plate synchronously drives the adjusting arm to rotate. The adjusting arm then pushes the moving plate along the slide rod via the drive shaft. The moving plate reciprocates on the slide rod, thereby pushing the automotive gas springs on both sides to extend and retract, thus achieving the testing. Two automotive gas springs from different batches can be sampled and tested simultaneously, improving the efficiency of the sampling inspection. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-2 A device for detecting the number of extension and retraction cycles of an automotive gas spring includes a workbench 1, a drive disk 3 driven by a motor 2 installed in the middle of the workbench 1, an adjusting arm 4 slidably disposed in the middle of the drive disk 3 and limited by a pin 5, and a drive shaft 6 rotatably mounted on one end of the adjusting arm 4.

[0024] Two opposing movable plates 7 are installed between the two side plates of the workbench 1. The middle opening of the movable plate 7 is slidably connected to the drive shaft 6. Fixed plates 10 are provided on both sides of the movable plate 7. A limiting part 8 is installed on the fixed plate 10. A movable sleeve 9 that is rotatably connected to the fixed plate 10 is provided around the limiting part 8.

[0025] The middle of each of the two side plates of the workbench 1 is perforated by a screw 12, the position of which can be limited by a nut. A slider 14 is fixedly installed at one end of the screw 12. The slider 14 slides along the guide rail 13 fixed on the workbench 1. A limiting part 2 16 is also installed on the slider 14. A movable sleeve 2 15 that is rotatably connected to the slider 14 is provided around the limiting part 2 16.

[0026] Based on the measured length of the automotive gas spring, first adjust the position of the slider 14 on the guide rail 13. Then, rotate the nut on the screw 12 to restrict its movement (two nuts are set on the screw 12, located on the two sides of the side plate of the worktable 1). Multiple through holes are evenly opened on the adjusting arm 4. A threaded groove is opened at the sliding groove in the middle of the drive plate 3, so that the pin 5 can be screwed into the threaded groove after passing through the adjusting arm 4. Then, adjust the position of the adjusting arm 4 on the drive plate 3 (when installing the automotive gas spring later, ensure that one of the automotive gas spring piston rods is extended while the other automotive gas spring is in a telescopic state). The adjusting arm 4 is limited by threading the pin 5 through the through hole on the adjusting arm 4 and the threaded hole on the drive plate 3. At this time, the center distance between the drive shaft 6 and the drive plate 3 is adjusted.

[0027] The fixed plates 10 on both sides of the movable plate 7 are offset from the center point of the movable plate 7. A set of movable sleeve 1 9 on one side of the movable plate 7 and its nearest set of movable sleeve 2 15 are on a straight line parallel to the slide rod 11. The mounting parts at both ends of the car gas spring can be respectively fitted onto one set of movable sleeve 1 9 and the corresponding set of movable sleeve 2 15. Then, the nut of the limiting part 1 8 is screwed onto its stud, and the nut of the limiting part 2 16 is screwed onto the stud to restrict the mounting parts at both ends of the car gas spring from moving upward and slipping off the movable sleeve 1 9 and movable sleeve 2 15.

[0028] The outer ring of the drive shaft 6 is recessed in the middle, and the opening in the middle of the movable plate 7 is correspondingly set in the recessed part of the outer ring of the drive shaft 6. The highest point of the drive shaft 6 is lower than the lowest point of the movable sleeve 9. The circular block at the bottom of the movable sleeve 9 can support the mounting part of the car gas spring. Then the drive motor 2 can drive the drive disk 3 to rotate, and the drive disk 3 can simultaneously drive the adjusting arm 4 to rotate. At this time, the adjusting arm 4 pushes the movable plate 7 to slide along the slide rod 11 through the drive shaft 6. The movable plate 7 moves back and forth on the slide rod 11, thereby pushing the car gas springs on both sides to extend and retract to achieve detection.

[0029] The output shaft of motor 2 rotates at a constant speed, and the moving plate 7 moves back and forth along the slide bar 11 a constant number of times per minute. Thus, the number of extension and retraction cycles of the car spring rod can be detected by measuring the duration of the test.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
